Aim of the research is to increase efficiency mechanical and technological process separation sunflower seed mixture on vibro-pneumatic separators, principle which based interaction flow with surface having fluctuation-type vibration load by substantiating their efficient processing parameters. A system differential equations seeds motions, as a granular gas, under action vibrating was develope...

Natural convection heat transfer was investigated experimentally in a concentric-cylinders annulus. To enhance the rate of heat transfer, pin fins were installed on the surface of the inner cylinder. Two fin arrangements were employed, namely, staggered and in-line arrangements. The length of the fins varied from 2 to 8 cm and the Rayleigh number Ra changed in the range from 5 x 105  to 5 x 106...

multiple sclerosis (ms) is one of the autoimmune diseases with an unknown cause. the aim of this study was to explore the link between air quality and ms relapses in patients who suffer from ms.this time-series study was conducted on patients registered at the iranian multiple sclerosis society in 2011-2012. they were randomly selected from patients lived in tehran in the last five years, and h...

Experience management refers to the capture, structuring, analysis, synthesis, and reuse of an organization’s experience in the form of documents, plans, templates, processes, data, etc. The problem of managing experience effectively is not unique to software development, but the field of software engineering has had a high-level approach to this problem for some time. The Experience Factory is...

Recently Perlmutter et al. (1999) suggested a positive value of Einstein’s cosmological constant Λ on the basis of luminosity distances from type-Ia supernovae (the “SN-method”). However, Λ world models had earlier been proposed by Hoell & Priester (1991) and Liebscher et al. (1992a,b) on the basis of quasar absorption-line data (the “Q-method”). Employing more general repulsive fluids (“dark e...

The introduction of advanced Air Traffic Management (ATM) functionality is often heralded as a safety improvement. On the whole, the introduction of advanced ATM functionality will probably reduce the likelihood of an accident. However, its introduction may also entail new sources of safety risk that need to be carefully weighed against the safety benefits of advanced ATM functionality. Many ne...

As operation frequencies and performance requirements of wireless devices increase, the resultant demands on the performance of passive components also increase. Miniaturization of inductive components for high frequency has been a key research area to address this issue; however, in general, miniaturized integrated inductors can suffer from low Q factors and/or self-resonant frequencies when c...

This paper describes a software architecture for mission-level control of autonomous unmanned air vehicles (UAVs). The architecture provides for sensor data fusion, worldview generation, and mission planning and execution. Details about the airborne platform and a high-level description of the control architecture are provided. As an example of the architecture’s versatility a formation flight ...

Divers and hyperbaric chamber attendants breathe hyperbaric air routinely. Hyperbaric oxygen (HBO(2)) is used therapeutically frequently. Although much is understood about the hemodynamic physiology and gas exchange effects during hyperbaric air and HBO(2) exposure, arterial and pulmonary arterial (PA) catheter data, including blood gas values during hyperbaric air and HBO(2) exposure of normal...

This report is one in a series of Software Engineering Institute (SEI) case studies on software architecture. It describes structural modeling, a technique for creating software architectures based on a small set of design elements called structural types. Structural modeling resulted from the efforts of the Air Force Aeronautical Systems Command (ASC/YW) and has been used by Air Force contract...
