what are the latest technology or gadgets in the field of electrical engineering?

hello. i need some latest technology or gadgets that are being used in the field of electrical engineering. example is infrared thermal scanner which is being used in detecting problems in transmission lines. i am going to use it in my report in one of my subjects. thank you very much

Answer
well there are tons of them, just check adds and articles in trade journals (many are online).
there is tons of wireless products, for example wireless sensors for robotic cells:
robots are moving quite a bit and even best cables tend to break after while. this causes downtime, specially on inputs (sensors) because they are low power and if the problem is intermittent, this can take forever to isolate and fix. in manufacturing where stations are organizes in production lines, downtime at one station is disaster. solution is to have sensors that both receive power and send signals wirelessly (near field only). but there are so many others (3D cameras by Sick for example etc.).

Does anyone know anything about x-ray microtomography?

Clark H

Hello! Please help me and my group with our assignment at uni! We have been asked to write a 3-page essay about x-ray microtomography. But it seems rather difficult to find information about that topic on the internet and in published texts. We would like any information available! Thanks a lot!

Answer
Microtomography, like tomography, uses x-rays to create cross-sections of a 3D-object that later can be used to recreate a virtual model without destroying the original model. The term micro is used to indicate that the pixel sizes of the cross-sections are in the micrometer range. This also means that the machine is much smaller in design compared to the human version and is used to model smaller objects.

These scanners are typically used for small animals (in-vivo scanners), biomedical samples, foods, microfossils, and other studies for which minute detail is desired.

The first X-ray microtomography system was conceived and built by Jim Elliott in the early 1980s. The first published X-ray microtomographic images were reconstructed slices of a small tropical snail, with pixel size about 50 micrometers. (JC Elliott and SD Dover. X-ray microtomography. J. Microscopy 126, 211-213, 1982.)

In 2005, Skyscan, a company that produces scientific instruments, introduced a nano-ct scanner, introducing the concept of Nanotomography. Other companies producing such scanners include Xradia for materials and semiconductor applications and Scanco Medical AG for medical applications.

Working principle

* Imaging system

Fan beam reconstruction
The fan-beam system is based on a 1-dimensional x-ray detector and an electronic x-ray source, creating 2-dimensional cross-sections of the object. Typically used in human Computed tomography systems.
Cone beam reconstruction
The cone-beam system is based on a 2-dimensional x-ray detector (camera) and an electronic x-ray source, creating projection images that later will be used to reconstruct the image cross-sections.

* Sample holder system

The sample stays still, and the camera and electronic x-ray source rotates.
This is best used for in-vivo animal scans, and other situations where the sample should remain unmoving, but is more expensive.
E.g.SkyScan-1076 or SkyScan-1078 or Scanco VivaCT 40 scanners for sample details.
The sample rotates, and the camera and electronic x-ray source stays still.
Much cheaper to build, since moving the sample requires fewer components than moving the camera and the electronic x-ray source.

* Open/Closed systems

Open x-ray system
In an open system, x-rays may escape or leak out, thus the operator must stay behind a shield, have special protective clothing, or operate the scanner from a distance or a different room. Typical examples of these scanners are the human versions, or designed for big objects.
E.g. Scanco medical XtremeCT scanner.
Closed x-ray system
In a closed system, x-ray shielding is put around the scanner so the operator can put the scanner on his desk or special table. Although the scanner is shielded, care must be taken and the operator usually carries a dose meter, since x-rays have a tendency to be absorbed by metal and then re-emitted like an antenna. Although a typical scanner will produce a relatively harmless volume of x-rays, repeated scannings in a short timeframe could pose a danger.
Closed systems tend to become very heavy because lead is used to shield the x-rays. Therefore, the smaller scanners only have a small space for samples.
E.g. SkyScan-1076 or SkyScan-1078 or Scanco mCT 40 or Scanco mCT 80 scanners

Typical use
* Biomedical

* Both dead and alive (in vivo) rat and mouse scanning.
* Human skin samples, small tumors, mice bone for osteoporosis research.

See in vivo microCT scanners for scanning examples.

* Electronics

Small electronic components. E.g. DRAM IC in plastic case.

* Microdevices

E.g. spray nozzle

* Composite materials and metallic foams

E.g. composite material with glass fibers 10 to 12 micrometres in diameter

* Polymers, plastics

E.g. plastic foam

* Diamonds

E.g. detecting defects in a diamond and finding the best way to cut it.

* Food and seeds

* E.g. piece of chocolate cake, cookies
* 3-D Imaging of Foods Using X-Ray Microtomography [1]

* Wood and paper

E.g. piece of wood to visualize year periodicity and cell structure

* Building materials

E.g. concrete after loading.

* Geology

E.g. sandstone

* Microfossils

E.g. bentonic foraminifers

* Space

E.g. Locating Stardust-like particles in aerogel using x-ray techniques [2]

* Others

E.g. cigarettes

* Stereo images

Visualizing with blue and green or blue filters to see depth

What is an optical scanner and how does it work?

huzaifai

Answer
in computing, a scanner is a device that analyzes an image (such as a photograph, printed text, or handwriting) or an object (such as an ornament) and converts it to a digital image. Most scanners today are variations of the desktop (or flatbed) scanner The flatbed scanner is the most common in offices. Hand-held scanners, where the device is moved by hand, were briefly popular but are now not used due to the difficulty of obtaining a high-quality image. Both these types of scanners use charge-coupled device (CCD) or Contact Image Sensor (CIS) as the image sensor, whereas older drum scanners use a photomultiplier tube as the image sensor.

Another category of scanner is a rotary scanner used for high-speed document scanning. This is another kind of drum scanner, but it uses a CCD array instead of a photomultiplier.

Other types of scanners are planetary scanners, which take photographs of books and documents, and 3D scanners, for producing three-dimensional models of objects.

Scanners typically read red-green-blue color (RGB) data from the array. This data is then processed with some proprietary algorithm to correct for different exposure conditions and sent to the computer, via the device's input/output interface (usually SCSI or USB, or LPT in machines pre-dating the USB standard). Color depth varies depending on the scanning array characteristics, but is usually at least 24 bits. High quality models have 48 bits or more color depth. The other qualifying parameter for a scanner is its resolution, measured in pixels per inch (ppi), sometimes more accurately referred to as samples per inch (spi). Instead of using the scanner's true optical resolution, the only meaningful parameter, manufacturers like to refer to the interpolated resolution, which is much higher thanks to software interpolation. As of 2004, a good flatbed scanner has an optical resolution of 1600â3200 ppi, high-end flatbed scanners can scan up to 5400 ppi, and a good drum scanner has an optical resolution of 8000â14,000 ppi.

Manufacturers often claim interpolated resolutions as high as 19,200 ppi; but such numbers carry little meaningful value, because the number of possible interpolated pixels is unlimited. The higher the resolution, the larger the file. In most cases, there is a trade-off between manageable file size and level of detail. Resolutions higher than 1200dpi are overkill for colour printers and monitors.

The third important parameter for a scanner is its density range. A high density range means that the scanner is able to reproduce shadow details and brightness details in one scan.

can i know about history of scanner?

Another category of scanner are digital camera scanners which are based on the concept of reprographic cameras. Due to the increasing resolution and new features such as anti-shake, digital cameras become an attractive alternative to regular scanners. While still containing disadvantages compared to traditional scanners, digital cameras offer unmatched advantages in speed and portability.

MRI vs Cat scan.....?

lilkay

my docter says i need an MRI but i would rather not get that..

is a cat scan possible to get instead?
can a cat scan show muscles and nerves?

Answer
MRI

Magnetic Resonance Imaging (MRI), or nuclear magnetic resonance imaging (NMRI), is primarily a medical imaging technique most commonly used in radiology to visualize the internal structure and function of the body. MRI provides much greater contrast between the different soft tissues of the body than computed tomography (CT) does, making it especially useful in neurological (brain), musculoskeletal, cardiovascular, and oncological (cancer) imaging. Unlike CT, it uses no ionizing radiation, but uses a powerful magnetic field to align the nuclear magnetization of (usually) hydrogen atoms in water in the body. Radio frequency (RF) fields are used to systematically alter the alignment of this magnetization, causing the hydrogen nuclei to produce a rotating magnetic field detectable by the scanner. This signal can be manipulated by additional magnetic fields to build up enough information to construct an image of the body.[1]:36

CAT scan

Computed tomography (CT) is a medical imaging method employing tomography. Digital geometry processing is used to generate a three-dimensional image of the inside of an object from a large series of two-dimensional X-ray images taken around a single axis of rotation. The word "tomography" is derived from the Greek tomos (slice) and graphein (to write). Computed tomography was originally known as the "EMI scan" as it was developed at a research branch of EMI, a company best known today for its music and recording business. It was later known as computed axial tomography (CAT or CT scan) and body section rÃ¶ntgenography.

CT produces a volume of data which can be manipulated, through a process known as "windowing", in order to demonstrate various bodily structures based on their ability to block the X-ray/RÃ¶ntgen beam. Although historically the images generated were in the axial or transverse plane, orthogonal to the long axis of the body, modern scanners allow this volume of data to be reformatted in various planes or even as volumetric (3D) representations of structures. Although most common in medicine, CT is also used in other fields, such as nondestructive materials testing. Another example is the DigiMorph project at the University of Texas at Austin which uses a CT scanner to study biological and paleontological specimens.

you can find out more on wikipedia, that is where i got this. or just go ask your doctor. but i would say you could do either, depending on what your insurance covers and how much you are will/able to pay.

How far is the automated 3-D segmentation of Brain MRI efficient compared to manual segmentation?

Sandhya

We are doing a project on automated 3-D segmentation of brain MRI using MATLAB. We would like to know the extent to which "Surf" commands are efficient in producing reliable segmented 3-D image. The accuracy level, how much it is better compared to manual segmentation. We need statistical detail, kindly help us....

Answer
This correspondence deals with the development of an
automated 3-D segmentation of Brain MRI. The proposal is a
model-based approach for accurate, robust, and automated
tissue segmentation of brain MRI data of single as well as
multiple magnetic resonance sequences. The main contribution
of this study is that we employ an edge-based geodesic active
contour for the segmentation task by integrating both image
edge geometry and voxel statistical homogeneity into a novel
hybrid geometricâstatistical feature to regularize contour
convergence and extract complex anatomical structures. We
validate the accuracy of the segmentation results on simulated
brain MRI scans of both single T1-weighted and multiple T1/
T2/PD-weighted sequences. When compared to a current stateof-
the-art region based level-set segmentation formulation,
our white matter and gray matter segmentation resulted in
significantly higher accuracy levels with a mean improvement
in Dice similarity indexes. Thus the development of the project
is done using MATLAB simulation for results.
A Hybrid Automated 3D Segmentation in Brain MRI -------------------------------------------------------- Advantages of a MRI scan
â¢ MRI scanners are good at looking at the non-bony parts
or "soft tissues" of the body. In particular, the brain, spinal
cord and nerves are seen much more clearly with MRI
than with regular x-rays and CAT scans.
â¢ Also, muscles, ligaments and tendons are seen quite well
so that MRI scans are commonly used to look at knees
and shoulders following injuries.
â¢ A MRI scanner uses no x-rays or other radiation.
â¢ A disadvantage of MRI is itâs higher cost compared to a
regular x-ray or CAT scan. Also, CAT scans are frequently
better at looking at the bones that MRI.

What can I use to cast a mold from stone without hurting the stone?

disciple

I'm new to this, but does anyone know what medium I would use to make a mold from a stone. In other words, There is an old building with a beautiful design sculpted in to it. I want to copy this design. I know there is a material out there that I can press against the original design and make a mold of it and then cast the design in plaster. I just don't know what material I would use to do this without hurting the stone.... Help!!!

Answer
I think the sculpey or any clay will work. If you use normal clay, any residue left will dissolve in the next rain, just don't use brown clay on light stone... if you use water based clay you would have to cast your plaster into the mold while the clay is still wet.
As the clay won't be very stable just on its own, you should consider making a mother mold on top of that. That is a hard shell, which just gives support to the soft part of your mold so it doesn't deform. It depends on the size of what you want to copy if you need it. You could make the mothermold from plaster bandages, but don't put plaster directly on the stone.
Before you start, consider carefully the shape of what you want to copy and where undercuts are and where you have to put in parting lines. What technique you use for mold making really depends on the exact shape of what you want to copy. If the structure is something complicated, you may want to practice how to make molds from more simple structures first so you are aware what causes problems and get some experience in how to solve them.

Another completely contact free method is if you happen to be at a university where they have a 3D laser scanning camera you can borrow, you could use the 3D laser scanner then make a model of your structure in the computer from the scans. That you could print out using a 3D printer. that way you can scale the model to any size (though anything large will be expensive to print)

In what ways do robots help humans?

In what ways? do they make our jobs easier. and how do they help us

Answer
Contemporary uses
Main articles: Industrial robot and Domestic robot

Robots can be placed into roughly two classifications based on the type of job they do. The first category includes tasks which a robot can do better than a human. Here, robots can increase productivity, accuracy, and endurance. The second category consists of dirty, dangerous or dull jobs where it is desirable to replace human labor with robotics.

[edit] Increased productivity, accuracy, and endurance
A Pick and Place robot in a factory

Many factory jobs are now performed by robots. This has led to cheaper mass-produced goods, including automobiles and electronics. Stationary manipulators used in factories have become the largest market for robots. In 2006, there were an estimated 3,540,000 service robots in use, and an estimated 950,000 industrial robots. [35] A different estimate counted more than one million robots in operation worldwide in the first half of 2008, with roughly half in Asia, 32% in Europe, 16% in North America, 1% in Australasia and 1% in Africa.[36]

Some examples of factory robots:

* Car production: Over the last three decades automobile factories have become dominated by robots. A typical factory contains hundreds of industrial robots working on fully automated production lines, with one robot for every ten human workers. On an automated production line, a vehicle chassis on a conveyor is welded, glued, painted and finally assembled at a sequence of robot stations.
* Packaging: Industrial robots are also used extensively for palletizing and packaging of manufactured goods, for example for rapidly taking drink cartons from the end of a conveyor belt and placing them into boxes, or for loading and unloading machining centers.
* Electronics: Mass-produced printed circuit boards (PCBs) are almost exclusively manufactured by pick-and-place robots, typically with SCARA manipulators, which remove tiny electronic components from strips or trays, and place them on to PCBs with great accuracy.[37] Such robots can place hundreds of thousands of components per hour, far out-performing a human in speed, accuracy, and reliability.[38]

Automated guided vehicle carrying medical supplies and records

* Automated guided vehicles (AGVs): Mobile robots, following markers or wires in the floor, or using vision[39] or lasers, are used to transport goods around large facilities, such as warehouses, container ports, or hospitals.[40]

*
o Early AGV-Style Robots were limited to tasks that could be accurately defined and had to be performed the same way every time. Very little feedback or intelligence was required, and the robots needed only the most basic exteroceptors (sensors). The limitations of these AGVs are that their paths are not easily altered and they cannot alter their paths if obstacles block them. If one AGV breaks down, it may stop the entire operation.

*
o Interim AGV-Technologies developed that deploy triangulation from beacons or bar code grids for scanning on the floor or ceiling. In most factories, triangulation systems tend to require moderate to high maintenance, such as daily cleaning of all beacons or bar codes. Also, if a tall pallet or large vehicle blocks beacons or a bar code is marred, AGVs may become lost. Often such AGVs are designed to be used in human-free environments.

*
o Newer AGVs such as the Speci-Minder,[41] ADAM, [42] Tug[43] and PatrolBot Gofer[44] are designed for people-friendly workspaces. They navigate by recognizing natural features. 3D scanners or other means of sensing the environment in two or three dimensions help to eliminate cumulative errors in dead-reckoning calculations of the AGV's current position. Some AGVs can create maps of their environment using scanning lasers with simultaneous localization and mapping (SLAM) and use those maps to navigate in real time with other path planning and obstacle avoidance algorithms. They are able to operate in complex environments and perform non-repetitive and non-sequential tasks such as transporting photomasks in a semiconductor lab, specimens in hospitals and goods in warehouses. For dynamic areas, such as warehouses full of pallets, AGVs require additional strategies. Only a few vision-augmented systems currently claim to be able to navigate reliably in such environments.

[edit] Dirty, dangerous, dull or inaccessible tasks
A U.S. Marine Corps technician prepares to use a telerobot to detonate a buried improvised explosive device near Camp Fallujah, Iraq

There are many jobs which humans would rather leave to robots. The job may be boring, such as domestic cleaning, or dangerous, such as exploring inside a volcano.[45] Other jobs are physically inaccessible, such as exploring another planet,[46] cleaning the inside of a long pipe, or performing laparoscopic surgery.[47]

what do you think about my new camcorder idea?

Q. it's for a 3D SHD (Super High Definiton) camcorder.

just got an idea for a new type of camcorder. ths one uses a red, green, and blue laser (horizontally) and captures the 3 colors then adds them together to make a color image. The image colors are defines by reflected light. It's in 3D because it's calculating the time it takes for different parts of the picture to come back to it, and very slight differences define the bumps, objects, and textures.

What do you think? would it work? it's meant to stay in one place and the horizontal laser moves up and down a set feild of view very quickly. it's not meant to replace camcorders. lol

Answer
the basic concept is feasible. the very first video cameras used this method, they were called flying spot scanners. processing 2 megapixels 30 times per second for phase delay would be a tough task for a Cray computer. But holograms, or 3D still images, are created by lasers that generate an interference pattern directly, not computed. And holographic projection would be a prefered display technology.

Has anyone had a level 2 ultrasound? Can you explain?

Lis

NOT A 3D. Just a normal scan that is more detailed and they go through thoroughly looking for defects etc. and give you a better picture of what is going on with your child...I am just a bit nervous about an appt I have on Wednesday.

Answer
I'm assuming you mean the 20 week one? Here in UK we call that anomaly scan. The scan is a routine one offered to all pregnant women about 20 weeks into their pregnancy and is designed to screen for any potential problems with the organs, skeleton, skin and development. Some places can also tell you the sex.

This is an enjoyable scan for most parents and the likelihood of a problem is small- in less than 2% of scans we detect a problem and in most of those the problem is minor. Some major problems can also be detected at previous scans so if all looked healthy at your 12 week scan, and you've not had any problems since, then chances are high your baby is fine.

The scan itself is like all ultrasounds- performed by a qualified doctor, midwife or sonographer ina darkened room, where ultrasound jelly is applied to your abdomen then the scanner placed on your bump to give the image on screen. The scan lasts about half an hour, and you'll be given pictures of your baby afterwards.

Some places say you need a full bladder, but I don't recommend this after 16 weeks as it can actually obscure the view.

Good luck and congratulations on your baby.

Poll: Why do we smile?

Regenerate

Well, why do we?

Answer
Smiles are generally accepted as a universal facial expression of happiness or joy. We get instincts about which smiles are more genuine, are more felt than others, and which are more forced and more politely construed. I wanted to find out whether smiles are a social reaction- something learned amongst society- or whether thereâs an actual biological reason why, when we are given a positive stimulus, our cheeks bulge and the corners of our mouths turn upward. I started with the understanding that because it would be difficult or impossible to define happiness on an individual level, which I am taking to be the stimuli of the smiles themselves, the results would have to be more generalized and the findings would probably be somewhat controversial and less conclusive. I proposed that smiling was more directly linked to a physical, neurobiological response than to social interactions, because I assumed that there had to be some reason why even the most creative and brilliant of thinkers followed the rest and smiled to show pleasure.

For this paper, I chose to define happiness or pleasure as something we instinctually, consciously think we enjoy. I read that there are different types of smiles, which are often grouped into two categories, âDuchenne smilesâ, and âPan American smilesâ (1). The âDuchenne smileâ, named after researcher Guillaume Duchenne, involves the movement of the zygomaticus major muscle near the mouth, and the orbicularis oculi muscle near the eyes. It is believed that this smile can only be produced as a result of genuine positive emotion, making it involuntary. By contrary, the âPan American smileâ involves only the zygomaticus muscle, and is entirely voluntary, being used more often used to show politeness or mask true emotion (2). This suggests a partial control we have over the kind of smile we show when it comes to realizing that we need to put a smile on our faces for social approval, but little control over smiling about things that genuinely make us happy.

Stroke victims help us understand more of the distinctions between these two types of smiles. When they have had damage to their motor cortex, they often cannot physically concoct their faces into smiles voluntarily, but can smile Duchenne, involuntary smiles, when given a positive stimulus (3). Those having more damage to the deeper-seated basal ganglia can smile on command, but canât smile as an involuntary reaction, for example, when they hear something they find funny (4). This shows a difference in the roles of different muscles and neurons when it comes to the different types of smiling, suggesting a correlation between not being able smile voluntarily with injury to the motor cortex, and not being able to smile spontaneously with injury to the basal ganglia. The latter is often seen in Parkinsonâs disease patients, in whom the basal ganglia degenerate, and there becomes impairment to voluntary movement, with much loss of involuntary movement, including tics, as well (5).

While this shows that different parts of the brain and different brain messengers control different functions, I wanted to combine that with the social factor of smiling in an attempt to put it all together to determine how smiles work. Many studies have indicated that smiling is an innate reaction (1), most often due to happiness. This claim has been made as a result of several factors, including being based on studies of fetuses and children at young ages.

Since 2001, a four-dimensional scanner has been used to allow doctors to see that babies in the womb exhibit facial expressions (6). With the corners of the mouth turned up and the cheeks bulging, obstetrician Stuart Campbell, whoâs in charge of this new discovery, says, âwhatâs behind the smile, of course, I canât say, butâ¦ I think it must be some indication of contentment in a stress-free environmentâ (6). The 4D scanner, which also produces 3D images that move in real time, shows that babies start making finger movements at 15 weeks, yawning at 18 weeks, and smiling, blinking, and crying at 26 weeks. After birth, infants do not usually smile until they are 6 weeks old, creating a further interest to survey the womb and why there is this gap of time where no smiling occurs, perhaps because the infant must adjust to its new, less content surroundings. This new information on the subject suggests that perhaps smiling is a reflex to positive feelings, while at the same time can also be a response to hearing social communications from inside the womb.

Another interesting study was done on feral children who live in isolation from human contact and have remained unaware of human social behavior and unexposed to language (7). While there having only been just over a hundred reported cases, these children generally do not smile (1). Isolated from human interaction, they lend an interesting view to the question of why we smile. Since there are so few that are feral, placing great emph

77.78.246.143 Malware detected when I am on Kaspersky's website?

Lenny

Okay so I was on their website and when I tried to visit the following page on their website:

http://kasperskyusa.com/files/?file=kis&lang=en&ver=2011&pn=Downloads+%7C+Product+Updates+%7C+Kaspersky+Internet+Security

I get a malware warning saying that webarh.com hosts malware. Since I was on kaspersky website I thought the warning was wrong so I clicked the procceded anyway button and then it says http://77.78.245.115 hosts malware. Again I thought the warning was a mistake so clicked proceed anyway. It then brought me to:
http://77.78.246.143/index.php?51y6=1CKC77S028UH63232&M4EK=MRgtaV&ODAT=0&tQi6=aJkkgVm4qLz9cUipMRlE4LUpPBQMcBANkH3B4bmd5bwk2AUtyRWVOdG4DIWRrZwQBAmUFClxSV34BIAMjCAJ7L3JRBzIGBg4peQQLBQAHDQJkBjYtKz0%3D&mWr=VDXhR&0ZUP=9T606T33931K3B5A1&67=52T1BHXIHV9J07C9Q2CX3GTXPUZ

which is a fake virus scanner. I know it is fake because it opens in the browser and you cannot click on the buttons. For example one of the drives it shows is a floppy drive which I do not have. I already have downloaded Kaspersky Complete Internet Security 2011 a few days ago and I'm scanning now.

This does not happen when I visit other websites. Why would Kaspersky bring you to Malware??? Has it been hacked???
Before I was on usa.kaspersky.com but when I visited one of the pages on it, it brought me to kasperskyusa.com. This is the link I gave you above.

Answer
I do believe Kaspersky has been hacked. I also went to their correct web site for downloading their software, which is http://usa.kaspersky.com/downloads/product-updates. However, you will be redirected to a Malware site that infects your computer. I led my own father down that road tonight and he followed the links and infected his computer. Nice security Kaspersky!! And I thought Kaspersky had real potential. It is unacceptable for a security company to be hacked like this.

FYI, Kaspersky has taken their download site offline now. They have finally firgured out they were hacked. No ETA on how long it will take for them to issolate the security issue and fix it. I am sure they will get great news press and reviews after this breach.

What is an optical scanner and how does it work?

Why all the hoopla over 3d printer guns?

Obama fail

What are the odds that normal folks have 2 - 50k to shell out for the machines that do this stuff. Just more hysteria from the media.

Latest example at nypost.com

Answer
Oh, you mean the thought that for say $5,000-$10,000 a group of terrorists like the Arian Brotherhood could create an arsenal of untraceable guns that could pass right through airport scanners, is all right with you? Well, it is NOT alright with 90% of Americans.

I have worked with 3D printers and the current generation IS capable of creating weapons that are untraceable and undetectable by airport scanners. And once you understand the process and practice creating the raw materials to print with you can literally create ceramic guns and cartridges and bullets that can't be detected by airport scanners. So what if one out of ten crack in the kiln if you are creating 1,000 that still leaves 900 working firearms.

How are video games projected on screen?

Lp182

I know that we aren't actually looking at a constant moving video game and that all we are seeing are multiple frames per second. But how is it done? I'm just curious how they do it. And are video games only projected at 30 frames and 60 frames per second, or are there other # of frames that can be shown in a given second?

Answer
The numbers 30 and 60 are a side effect of the NTSC format of television. Even back in the black-and-white days of TV, NTSC was a 640X480 image, interlaced (draws all the odd lines in one pass, then draws all the even lines on the next), and operating at 60 Hz. It wasn't until about 10 years ago that consumers started seeing any change to this, when EDTVs came on the scene and changed the interlaced to Progressive Scan (all lines are drawn sequentially on each pass), and then HDTVs changing the image resolution. Very recently, sets that can do 120 Hz have come onto the market. In Europe, they uses the PAL format, which ran at 50 Hz, but switched to 60 Hz for HDTV to simplify things for TV manufacturers (who had started to sell sets in Europe that could handle both 50 Hz and 60 Hz).

So for the longest time, TVs were displaying 60 half-frames (due to interlacing). As such, having a game run at 60 Hz would result in slightly smoother animation, but a lot more processing power which could otherwise be used to enhance the detail. So typically 60 frames games were smoother, but 30 frames games were much more detailed. Any other rate, and you the smoothness will vary, which is rather jarring to the immersiveness factor.

All of this only applies to consoles, though, since PCs have always had monitors that could do a variety of framerates, and therfore their games always strived for the highest framerate possible (and where 60 Hz is on the far low end) and don't really worry about the framerate dipping at times. High end modern monitors can typically do at least 140 Hz, and some older games on new hardware can actually create several hundred frames per second if certain settings are disabled.

Regardless of PC or console, the same programming technique is used for creating the frames and managing the process of sending them to the screen. Each object is placed in position in a virtual 3D space in RAM, textures are applied (only if they are facing the virtual camera's location), the view from the virtual camera is established, and the objects that the camera can see are flattened into a 2D image. This whole process is called rendering.

Then, the rendered image is put into a piece of memory (usually in the graphics chip itself) that has been designated as a "frame". This frame is then sent to the TV/monitor, and as it is being sent, a second image is being rendered and put into a second "frame". Once the first frame has been sent to the screen completely, the second frame is designated as the primary frame, and a third image is rendered and overwrites the first frame. This process is called Frame Buffering.

PCs (and maybe HDMI TV connections, I'm not sure) have the capability of the monitor being able to send a signal back to the game program and tell it when a frame is done being drawn. This allows the game to not switch frames while it is being sent to the screen (vertical synch), preventing a top section of an image and a bottom section of the same image displayed not matching up, refered to as "tearing". Since consoles know what frequency the TV is operating at based on the region (or more recently in Europe, through an option in the settings for either the game or the system), they can simply use an internal timer as an artificial vertical synch.

In the video game industry, what does an environment designer & character designer do in order?

Q. Do they draw an environment & characters first? And then scan it to a computer & then make the video game using a software or what? Lol

Answer
Most concepts start out as drawings and paintings than could be done in traditional media or on the computer. The concept art then goes to various departments to be interpreted and refined as a digital product. Usually a 3d modeler will create a character or environment in the computer using the concept art as a reference.

A character might be sculpted first in clay, and then digitally scanned to create a 3d model.

The 3d model then goes to a rigger who creates the animatable "skeleton" and controls inside the character. This is what the animator uses to move the character.

my Windows Experience Index Dropped?

Q. I have an Alienware m11x...I updated some drivers from the manufacturer's website and made sure they were the latest ones. My index score for Gaming Graphics (3D business and gaming graphics performance) just dropped from 6.5 to 4.4! What the hell happened??

Answer
drivers are communication packages that "speak" to the cpu and relevant hardware/software using it, in old drivers you are given specific settings for that one device, however new drivers dont have the same settings and run on new technology, you have downloaded the latest drivers, BUT now other drivers that matched your old drivers need to be updated so they can tie with each other again.

your old drivers had a better match with all your older drivers and settings, because you have updated them, the rest need updated aswel. new drivers dont like old drivers, especially in windows vista and windows 7. as these operating systems use a unique format to register drivers compared to xp.

download uniblue driver scanner (google it) and install and scan your system, takes 15 seconds, this will check ALL your drivers and download new drivers for you, but you choose what ones to install.

hope this helps.

How do I know which graphics card my laptop is using for which things?

Tom

My laptop has an intel HD graphics card onboard and also an nvidia graphics card. I have both enabled but when programs search for what graphics card I am using, the intel one shows up. Is the computer still using the nvidia card?
They're both internal and came with the laptop. Would the computer just automatically relegate desktop activities to the intel HD card and things like gaming to the nvidia card?
The only setting I can find in the power options for graphics say Intel(R) Graphics Settings - Intel(R) Graphics Power Plan - On Battery: Maximum Performance, Plugged in: Maximum Performance. I can't find a setting for the Nvidia card.

Answer
Try this scanner at Nvidia.
You need to install the driver so you can access the control panel.
http://www.nvidia.com/object/performance_group.html

If it is installed you will see a green icon by the clock.
Or right click the desktop and see if Nvidia Control panel is there.

You can also get the driver from your laptop manufacturer.
Go the the main page and click the Support link.

When you open the Nvidia Control Panel click on Manage 3D Settings and add your games and applications ".exe" name to the list. Then the Nvidia will be used when you run it.

What programs open RAW files?

chosen one

I think they are 3D programs or something like that

Answer
From wikipedia:

"A raw image file contains minimally processed data from the image sensor of a digital camera or image scanner. Raw files are so named because they are not yet processed and ready to use with a bitmap graphics editor, printed, or displayed by a typical web browser. The image must be processed and converted to an RGB format such as TIFF or JPEG before it can be manipulated."

You should then check out https://jrawio.dev.java.net/ , an Open Source Java program used to read RAW data from various digital camera models.

Can someone answer my questions about the 3-D printer?

Joey

Is there any limits to what it can make? Is it illegal to make certain things out of the 3D printer? If so,tell me. How much money is a 3D printer?If I put a puppy in the scanner, would it be able to replicate the puppy? How does the 3-D printer know if something should move or not?

Answer
Let me answer your questions one at a time:

1. Is there any limits to what it can make?
Right now, yes. In the future, no. The technology today is not advanced enough to make anything. The most common materials used now are plastic, resin, and recently the technology has grown to include metal. Food (lots of chocolate) has recently been printed as have organic materials such as stem cells. However, right now the biggest constraints of 3D printing is size. Soon one can conceivably print things as big as buildings, but for now most printers are relatively small (12in.X12in. though there are some much larger commercial printers). The future of 3D printing will also allow for printing on a molecular level, but for now the technology can only print in the micro scale.

2. Strictly speaking there are no laws against printing anything in 3D. However, laws exist that prohibit the manufacturing of certain goods and these apply to things that a 3D printer can conceivably make. An example of something that is illegal to print in the U.S. is a full gun. One can print parts of a gun legally, but cannot print a whole gun.

3. The cost of a 3D printer varies greatly. One can buy a 3D printer for the home for as little as $499. Commercial 3D printers cost much more and can run upwards of $30,000. With the continual advancement of the technology you can expect to see the prices drop as time goes on.

4. If you scan a puppy in 3D, a printer can print it in 3D. It would most likely be made out of plastic or resin though, not nice soft puppy fur.

5. 3D printers can print moving parts. When an item is programed into the software it maps out exactly where to lay down material. Because 3D printing is additive manufacturing it doesn't print the parts one by one, but instead prints the whole object layer by successive layer. If the programing is correct then moving parts can be included in the printed final product.

What animal has the strongest bite in the world?

John W

They said on Dirty Jobs that the alligator turtle has the 2nd strongest bite in the world, but what has the strongest bite?
Ali gators and Crocodiles have a very strong bite, so do Hippos. But is it one of those animals or is there something with a stronger bite?

Answer
GREAT white sharks really do have the meanest jaws on the planet, say experts.
The fierce ocean predators have a bite force of about 1.8 tonnes - that's 20 times more powerful than humans.
Even a large African lion, with a bite force of 560g, can't compare with the shark's massive mouth.
Scientists used the latest X-ray and scanner technology for their research.
The team at the University of New South Wales made 3D models of the skull of an 8ft male great white using images from a CT scanner.
They digitally "crash tested" their computer model to simulate different scenarios and reveal the powerful bite of the fearsome predator.
The experts also worked out the complex distributions of stresses and strains that these forces impose on the shark's jaws.
But even the great white seems small fry when compared with the carcharodon megalodon. Dubbed Big Tooth, it was a prehistoric shark that was 53ft long and had a bite of around 18 tonnes.
It hunted large whales by biting off their tail and flippers before feeding at will.
By comparison, T-Rex could only manage a bite force of around 3.1 tonnes.
Steve Wroe, the study's lead author, said: "Pound for pound, the great white's bite is not particularly impressive but the sheer size of the animal means that it tops the scales.
"It must also be remembered that its extremely sharp serrated teeth require relatively little force to drive them through thick skin, fat and muscle.
"Nature has endowed this carnivore with more than enough bite force to kill and eat large and potentially dangerous prey."
Great whites can grow to about 20 feet in length and live for 30-40 years.

Hope it helps you!

What is the difference between a traditional CT Scanner and a Spiral CT Scanner?

marshyanke

I know that a spiral produces thinner slices and perhaps in more detail, I am not really sure? I would like to better understand the science behind it? Also, could you respond with some understanding of MRI and Doppler scans as well? Could you provide some of the history of the above mentioned diagnostic tests? Thank you.

Answer
Computed tomography (CT), originally known as computed axial tomography (CAT or CT scan) and body section roentgenography, is a medical imaging method employing tomography where digital geometry processing is used to generate a three-dimensional image of the internals of an object from a large series of two-dimensional X-ray images taken around a single axis of rotation. The word "tomography" is derived from the Greek tomos (slice) and graphia (to write). CT produces a volume of data which can be manipulated, through a process known as windowing, in order to demonstrate various structures based on their ability to block the X-ray beam. Although historically (see below) the images generated were in the axial or transverse plane (orthogonal to the long axis of the body), modern scanners allow this volume of data to be reformatted in various planes or even as volumetric (3D) representations of structures.

Spiral CT scanning is just a new and advanced from of CT scanning: This is a newer type of CT scan, also known as a 'helical' CT scan. It is faster than a standard CT scan and gives an even more detailed picture of your organs and tissues, including blood vessels. This can make it useful for picking up very small tumours. It's called a spiral scan because the X-ray beam rotates around you during the scan in a spiral shape. This gives the radiographers a continuous picture, with no possible gaps between the 'slices' of the scan.

Core 2 Duo or Core 2 Quad?

Extreme Tw

Im building a computer and i am wondering which processor i should use. I dont game all that much, but i do use multiple operations at once at times. Should i go to Core 2 Duo and take the extra money to get more Ram?

Answer
Depends on what prices you can get both for. Core 2 Quad would be good if you do a LOT of multi-tasking, but otherwise a Core 2 Duo is fine too.

I personally use a Core 2 Duo (E4400, one of the slower models) and I can have like 20 tabs on Firefox, a 3D map editor, MSN and a virus scanner open without any slowdown (on 2 screens, too).

Can someone answer my questions about the 3-D printer?
