A high level of alertness is one of the most important requirements for people working in dangerous environments. We follow the approach of using wearable computers as guards. In this paper we propose a wearable alertness monitoring guard using physiological measures detecting eyelid closure, reaction time, head movements to determine the wearer’s actual alertness level.

One of the most intriguing areas of research in erythrocyte physiology is the interaction of hemoglobin with nitric oxide (NO). These two molecules independently fulfill diverse and complex physiological roles, while together they subtly modulate microvascular perfusion in response to second-by-second changes in local metabolic demand, contributing to hypoxic vasodilation. It is through an appr...

Current process improvement and maturity models pay little attention to requirements engineering. Typically, requirements engineering is considered to be a single activity in the overall development process. Even where this is not strictly the case, the requirements activities are not elaborated in sufficient detail to permit the derivation of an improvement plan. This is unfortunate because re...

This paper presents a language called ScreenSpec that can be used to specify screens at requirements elicitation phase. ScreenSpec was successfully applied in 8 real projects. It is very effective: average time needed to specify a screen is 2 minutes, and takes an hour to become proficient in using it. Visual representation generated from ScreenSpec can be attached to requirements specification...

Bryophyte communities can exhibit similar structural and taxonomic diversity as vascular plant communities, just at a smaller scale. Whether the physiological diversity can be similarly diverse, and whether it can explain local abundance patterns is unknown, due to a lack of community-wide studies of physiological traits. This study re-analyzed data on photosynthesis-related traits (including t...

New medical products, materials and surgical procedures keep improving current health-care practices. Many of these innovations involve polymeric devices that must meet certain clinical and cost requirements. Chief among these pressures is the need for biocompatibility between the physiological environment and the biomaterial surface. Plasma surface modification can improve biocompatibility and...

In this issue of Cell Stem Cell, Greco et al. (2009) characterize the hair germ as a novel stop between bulge stem cell and transient amplifying cells during hair regeneration. The work implies stem cell states can be regulated to form different numbers of intermediate stops, depending on physiological requirements.

Scenario Configuration  Complex system of multiple sensor nodes Ambient intelligence used to monitor physiological data WBAN simulation:  is essential before deployment in real world scenarios  is useful in studying energy efficiency requirements and application behavior  models the behavior of the medium access control (MAC) layer behavior which supports radio use of the physical (PHY) l...

BACKGROUND Nutritional requirements have been previously calculated for emergency-affected populations and are widely used for planning and assessing the nutritional adequacy of humanitarian food assistance. The Sphere Project is an interagency collaboration that defines minimum standards and indicators for humanitarian responses, including food and nutrition. It last published population nutri...
