This study evaluates three shading configurations designed and tested in a preliminary stage of responsive shading device development. The strategy is based on trigonometric relationships focused on solar angles at any given moment. The configurations are thus related to the ratio of the window area shaded by a responsive brise-soleil that provides 0%, 50%, or 100% shading of the indoor space, based on the daylight needs and the indoor thermal control realized. Shading simulations were performed for Pomona, Califor [...]

The integration of cyber and physical layer of the grid has not only introduced a microscopic spectacle to observe and ensure the efficient flow of electricity but has also exposed the interdependencies of the network. These cyber-physical interdependencies are often exploited in the form of cyber-attacks that can disable a grid introducing substantial financial losses and observable social repercussions. Thus, it is important to address the impending Achilles heel by devising pragmatic approaches to comprehensibly [...]

Let’s consider the issues of exercise and cognitive function from a different angle, by moving from sitting to standing for instance. Not only does seeing anything from different perspectives reflect our cognitive flexibility [1], it also has a direct impact on the executive performance. Interestingly, recent studies reported a smaller Stroop effect when standing than when sitting [2-3] or after stepping backward [4], evidencing that the body posture enhances selective attention and cognitive control. Hence a call [...]

Integration of behavioral health consultants and specialists into medical settings has accelerated the development of evidenced-based practices for an array of problems and concerns common to behavioral medicine. Though these treatments have shown to be beneficial for those that engage in protocols, attrition remains high. With an emphasis in directed problem solving and skill building, many brief treatments leave little room for compassion, validation, and understanding. This article explores this trend and advoca [...]

Across the industrial sector, compressed air is utilized as an easy-to-use and readily accessible tool in a variety of applications. This tool is commonly misunderstood as being more efficient than it is in reality. Air compression is energy intensive and thus both economically and environmentally costly. Compressed air typically only achieves around ~15% efficiency if judged by the energy delivered from the air, meaning approximately 5-6 kWh are wasted for every 1 kWh of useful work performed by compressed air.

Syncope is characterized by a transient and rapid loss of consciousness for a short duration, with full spontaneous recovery within minutes. Syncope causes up to 2% of all emergency medical consultations. The incidence of syncope is similar in men and women, is higher in old patients (slightly higher in old women). The prevalence of syncope is up to 23% for the institutionalized elderly. In elderly patients, syncope often presents atypically, such as with falls; these patients might also have difficulty recalling e [...]
