2017-11-11T04:20:31-08:00 December 6th, 2007|Biomedical Engineering, Health & Medicine, Issue IV, Volume IX|

Treating drug-resistant epilepsy and depression seemed impossible a few years ago. However, with the advent of Vagus Nerve Stimulation, treatment of these severe types of diseases is now possible. VNS therapy is a powerful new treatment that modulates some neural structures and functions to benefit those diagnosed with drug-resistant epilepsy and depression. Powered by an [...]

Modular Prefabricated Housing

2017-11-03T10:59:48-07:00 December 3rd, 2007|Building & Architecture, Civil Engineering, Issue I, Lifestyle, Volume IX|

This article will investigate the process of designing and building prefabricated, modular houses. Positive qualities such as eco-friendliness, cost-effectiveness and efficiency are reflected in the procedures of construction and use of materials. Modular housing has many advantages over traditional site-built houses, and it is suggested that the prefabrication housing technique can be one of the [...]

Power Wars: AC vs. DC

2017-11-11T04:12:26-08:00 December 3rd, 2007|Issue IV, Volume IX|

At the end of the 19th century, humanity captured power in its highest form: electricity. With a new magical power in the hands of great industrialists, a battle for ownership of the multi-million dollar future of its technological development ensued. The great engineer George Westinghouse dared do battle with Thomas Edison--fellow engineer and brilliant inventor--in [...]

What Makes Antibacterial Soap Antibacterial?

2017-11-03T11:00:23-07:00 December 1st, 2007|Chemical Engineering, Health & Medicine, Issue I, Volume IX|

Germs are everywhere, so it's no surprise that antibacterial soaps, hand sanitizers, and lotions are as well. Despite this, consumer knowledge of Triclosan (the active ingredient in many antibacterial products) remains vague at best. A biochemical explanation of how Triclosan disables bacteria will give consumers a more scientific understanding of a product they use so [...]

Automotive Telematics: A Technological Lifesaver

2017-11-03T10:33:12-07:00 October 9th, 2007|Communication, Issue I, Transportation, Volume IX|

Telematics, in its general sense, refers to the science of sending, receiving, and storing information via telecommunication devices. It is most notably known for its use in automotive vehicles through the application of global positioning systems. The variety of ways in which this technology may be used has only begun to make its presence known: [...]

Built for Sound: Architectural Acoustics

2017-11-11T03:56:07-08:00 September 15th, 2007|Building & Architecture, Entertainment, Issue I, Volume IX|

Architectural acoustics contribute significantly to the enjoyment of music. This is due to the relationship between a song and its intended performance venue. With the proper balance of acoustical intimacy and aliveness, performance venues are designed to accentuate the characteristics of symphonic music and provide the best listening experience possible. After enduring centuries of trial [...]

Underwater Habitats

2017-11-11T04:18:04-08:00 September 3rd, 2007|Building & Architecture, Energy & Sustainability, Issue IV, Lifestyle, Volume IX|

Last April, science hobbyist Lloyd Godson surfaced after surviving 13 days underwater in a lake near Albury, Australia. Godson's underwater habitat, the BioSUB, was designed to simulate a closed, autonomous environment. Using a Biocoil, a gas-exchange system that utilizes the photosynthetic properties of chlorella algae when supplied with carbon dioxide, light, and water, Godson was [...]

Motion Sensors

2017-11-11T04:14:34-08:00 September 3rd, 2007|Electrical Engineering, Energy & Sustainability, Issue IV, Volume IX|

Motion sensors are found everywhere today. This technology has helped accommodate our busy schedules by making our daily activities more efficient and convenient. These sensors were introduced by the demand for detection of enemy aircraft during World War II and were ultimately developed to apply to everyday life. With the demand of useful tools to [...]

Engineering Snow

2017-11-11T03:47:05-08:00 December 7th, 2005|Issue III, Sports & Recreation, Volume IX|

In the middle of the 20th century a device was invented that would forever change the way that ski areas operate -- the man-made snow machine. Snow sports enthusiasts have long been at the mercy of the weather to give them desired snow conditions. However, ski areas now rely significantly less on the weather to [...]

Turbochargers

2017-11-11T04:06:03-08:00 October 3rd, 2005|Energy & Sustainability, Issue III, Mechanical Engineering, Transportation, Volume IX|

Turbocharging, a technology originally developed for use in aircraft, is a current trend among automobile enthusiasts. Applying a turbocharger to an internal combustion engine increases the power output of that engine, allowing for greater acceleration and higher maximum speeds. Turbochargers increase an automobile's power-to-weight ratio by harnessing the exhaust from the engine. They can also [...]

The Danger of Airport Runway Crashes

2017-11-11T04:03:38-08:00 October 3rd, 2005|Aerospace Engineering, Industrial Engineering, Issue III, Transportation, Volume IX|

Runway incursions present a serious danger to airplane passengers today. Any time two planes, or a plane and vehicle, either come close to a collision or actually do collide on the runway surface can be described as an incursion. There are numerous factors that lead to runway incursions, and all of these must be taken [...]

The Trebuchet

2017-11-11T03:08:48-08:00 September 5th, 2005|History & Society, Issue II, Mechanical Engineering, Security & Defense, Volume IX|

The medieval battlefield was dominated by large artillery weapons, and among these the trebuchet was king. This massive weapon was eventually capable of throwing massive boulders over 250 meters, but it did not start that way. It took over 1000 years of innovation, experimentation, and modification to transform a moderately effective projectile-throwing machine into an [...]

2017-11-11T03:05:31-08:00 July 11th, 2005|Electrical Engineering, Issue II, Security & Defense, Volume IX|

In the post-September 11 era, engineers have developed new technologies to meet growing safety and security concerns at the world's airports. The drawbacks of existing security measures - especially physical pat downs - have provided a foundation for "backscatter" X-ray technology. Information offered by the Transportation Security Administration and American Science and Engineering, Inc., demonstrate [...]

Reflecting on the Mirrors

2017-11-11T04:01:52-08:00 April 26th, 2005|Electrical Engineering, Entertainment, Issue III, Material Science, Volume IX|

Advertisements for some new types of televisions claim that their superb picture quality is due to β€œthe mirrors.” These mirrors are on the order of microns wide, and millions of them reside in the back of DLP televisions. This way of projecting the light source is a cutting-edge method (over LCD and Plasma) that allows [...]
