UPSET: Triggering Natural Cell Death in Cancer

2019-01-10T11:16:30-08:00 April 28th, 2003|Biomedical Engineering, Issue I, Volume V|

Ultra-short Pulsed Systems Electroperturbation Technology (UPSET) has the potential to become a new cancer treatment due to its ability to trigger apoptosis, the natural death mode of cells. During apoptosis, a cell initiates a self-termination process to remove it without affecting surrounding tissue. UPSET generates and delivers pulses of 40 kV/cm and 20 nanoseconds in [...]

Improving the Bicycle

2017-11-03T17:22:30-07:00 December 28th, 2002|Issue I, Lifestyle, Transportation, Volume V|

Bicycles have been around for many years and are constantly being researched and improved. Many disciplines of science and engineering are necessary in making the bicycle what it is today and will be in the future. Since the appearance of the first bicycle in the late 1700s, this machine has evolved from a simple wooden [...]

The Quest for the Perfect Racket: Advances in Tennis Racket Design

2019-01-10T11:58:32-08:00 December 6th, 2002|Issue I, Mechanical Engineering, Sports & Recreation, Volume V|

The tennis racket has experienced continuous improvements to meet the performance demands of professional players. In designing a better tennis racket, engineers and scientists need to understand exactly what happens when the ball collides with the racket. The racket frame, strings, and tennis ball experience energy transfer, resulting in deformations of all three components. With [...]

Lie Detection: The Science and Development of the Polygraph

2019-01-10T12:08:08-08:00 December 6th, 2002|Biomedical Engineering, Issue I, Security & Defense, Volume V|

The idea of using a polygraph for lie detection emerged at the end of the nineteenth century. Despite major technological advances in the twentieth century, the polygraph has evolved little since its invention. The polygraph works under the assumption that lies can be detected by certain measurable physiological changes, a theory proposed more than 100 [...]

A Look At Surveillance Cameras

2019-01-10T12:00:04-08:00 December 6th, 2002|Computer Science, Issue I, Security & Defense, Volume V|

When taking a look around a public place, one may observe an increase in the use of surveillance cameras. This is partially due to technological advances that have introduced new benefits for businesses and law enforcement agencies that implement video surveillance. Current technology allows an operator to view live surveillance footage from a remote location [...]

Total Hip Replacement

2019-01-10T12:10:27-08:00 November 2nd, 2002|Health & Medicine, Issue I, Volume V|

Total hip replacement, or THR, is a very common and successful procedure. THR is often performed when wear of the hip joint -- due to osteoarthritis, rheumatoid arthritis, avascular necrosis, or a related condition -- results in extreme pain. The worn femoral head and acetabulum (the ball and socket respectively) are removed and replaced with [...]

The Search for a Blood Substitute

2019-01-10T12:17:20-08:00 November 2nd, 2002|Health & Medicine, Issue I, Volume V|

In recent years, America's blood shortage has propelled the biotechnology of blood substitutes. Artificial blood does not contain the plasma, red and white cells, or platelets of human blood, but functions to transport and deliver oxygen to the body's tissues until the recipient's bone marrow has regenerated the missing red blood cells. Current blood substitutes [...]

Reconfigurable Computing: Virtual “On-the-Fly” Hardware Swapping

2019-01-10T12:14:04-08:00 August 2nd, 2002|Computer Science, Issue I, Volume V|

A new hardware paradigm technology encompassing reprogrammable circuitry commands the versatility of general design processors and the speed of application-specific circuits. One manifestation of this design stratagem is the field programmable gate array, a collection of logic functions whose software controlled interconnections can be altered at will to optimize select processing requirements. This technology can [...]
