The Food and Drug Administration has mandated that the software development life cycle be used to ensure the quality of software used to report results of clinical trials. This paper examines how one of the newer approaches used in commercial software development, Extreme Programming (XP), can be applied in a SAS® programming environment to improve code quality and save development time. XP del...

Writing data in parallel is a common operation in some computing environments and a good proxy for a number of other parallel processing patterns. The duration of time taken to write data in large-scale compute environments can vary considerably. This variation comes from a number of sources, both systematic and transient. The result is a highly complex behavior that is difficult to characteriz...

Silicon-on-insulator MESFETs have been fabricated using standard CMOS process flows and their characteristics have been measured over a temperature range of –180°C to + 300°C. From the measured data a TOM3 Spice model has been extracted. The Spice model has been used to simulate a two-stage operational transconductance amplifier and a voltage controlled oscillator. The circuit simulations show ...

Extreme Programming (XP) is a new and controversial sojiware process for small teams. A practical training course at the university of Karlsruhe led to the following observations about the key practices of Xl? First, it is unclear how to reap the potential benejits of pair programming, although pair programming produces high quality code. Second, designing in small increments appears problemati...

Route planning problems are among the activities that have the highest impact on logistical planning, transport and distribution because of their effects on efficiency in resource management, service levels, and client satisfaction. The difficulty of movement between different customers and other problems cause the uncertainty of time of movement. In this paper this uncertainty is presented by ...

The deep-sea environment is characterized by high pressure and low temperature but in the vicinity of hydrothermal vents regions of extremely high temperature exist. Deep-sea microorganisms have specially adapted features that enable them to live and grow in this extreme environment. Recent research on the physiology and molecular biology of deep-sea barophilic bacteria has identified pressure-...

We studied soil nematode communities from the surface of granite flatrock outcrops in the eastern Piedmont region of the United States. The thin soils that develop here experience high light intensity and extreme fluctuations in temperature and moisture and host unique plant communities. We collected soils from outcrop microsites in Virginia (VA) and North Carolina (NC) in various stages of suc...

The femtosecond laser-induced fiber Bragg grating is an effective sensor technology that can be deployed in harsh environments. Depending on the optical fiber chosen and the inscription parameters that are used, devices suitable for high temperature, pressure, ionizing radiation and strain sensor applications are possible. Such devices are appropriate for aerospace or energy production applicat...

We present a hardware/software system for support of distributed Extreme Programming, or dXP. It consists of a dual video projector, dual PC setup, and an enhanced projected video display. dXP supports the development of software by pairs of programmers that are non-co-located. One projector displays a shared PC desktop, and another projector displays a life-sized image of each collaborator to ...

There are several pieces of evidence showing occurrence of pulmonary edema (PE) in healthy subjects in extreme conditions consisting of extreme psychophysical demand in normal environment and psychophysical performances in extreme environment. A combination of different mechanisms, such as mechanical, hemodynamic, biochemical, and hypoxemic ones, may underlie PE leading to an increase in lung v...
