One of the most ambitious efforts in value-centric design of a military aerospace system undertaken to date has been the parallel development by four performer teams, headlined by major space industry primes, of design tools for fractionated space architectures under DARPA's System F6 program. The goal of the System F6 program is to replace traditional, highly-integrated, monolithic satellites ...

OBJECTIVE Many work in injury prone awkward positions that require adequate flexibility and strength in trunk stabilizer muscle groups. Performance on a functional movement screen (FMS) that assessed those factors was conducted and an intervention was designed. METHODS A battery of FMS tests were performed on 433 firefighters. We analyzed the correlation between FMS performance and injuries a...

In recent years, multi-energy microgrid (MEM) has gained increasing interest, which could use clean and efficient electro-thermal resources, storages (MESs) demand response potential to improve the flexibility of MEM. However, maximizing MEM alongside managing electrical parameters (EPs) is a challenging modeling problem. this paper, probabilistic nonlinear model presented maximize with all pow...

TErrestrial Trunked Radio (TETRA) offers capabilities equivalent to the second generation of mobile phones with voice and limited data capabilities. TETRA needs to evolve to satisfy increasing user demand for new services and facilities as well as gleaning the benefits of new technology. An initial enhancement (TETRA Enhanced Data Service, TEDS) has been agreed. The enhanced TETRA services allo...

This paper considers the deadlock avoidance problem for the class of conjunctive / disjunctive (sequential) resource allocation systems (C/D-RAS), which allows for multiple resource acquisitions and flexible routings. A new siphon-based characterization of deadlocks arising in C/D-RAS is developed, and subsequently, this characterization facilitates the development of a polynomial-complexity de...

curve flexibility in adolescent idiopathic scoliosis (ais) was one of the major concerns of spinal surgeons since the evolution of surgical correction techniques. in this respect, many tried to identify which criteria denote more rigid curve. in the present study, we aimed toward determining important factors influencing ais curve flexibility on supine bending films. we assessed radiographs of ...
