Optimizing the control of battery temperature (Tb), while minimizing pressure drop (∆P) in air-cooled thermal management systems (TMSs), is an indispensable target for researchers. The Z-type system’s (BTMS’s) structure one widely investigated TMSs. Several designs BTMSs are often associated with drawback a rise ∆P, consequently resulting increase pumping costs. In this study, investigation step-like plenum design was extended by exploring and two outlets to determine possible decreases...

Detection of potential hijackings Unmanned Aerial Vehicles (UAVs) is an important capability to have for the safety future airspace and prevention loss life property. In this paper, we propose using basic statistical measures as a fingerprint flight patterns that can be checked against previous flights. We generated baseline flights then simulated hijacking scenarios determine extent feasibility method. Our results indicated all direct were detected, but with control instability caused by...

Over the past decade Unmanned Aircraft Systems (UAS, aka “drones”) have become pervasive, touching virtually all aspects of our world. While UAS offer great opportunity to better lives and strengthen economies, at same time these can significantly disrupt manned flight operations put very in peril. Balancing demanding competing requirements safely integrating into United States (US) National Airspace System (NAS) has been a top priority Federal Aviation Administration (FAA) for several...

Abstract This study compared television news coverage provided by embedded and nonembedded reporters during the first 5 days of Operation Iraqi Freedom (OIF). Content analysis was conducted broadcasts about OIF ABC, CBS, CNN, NBC to determine whether reports were different and, if so, how. The results indicated that, stories, more favorable in overall tone toward military depiction individual troops. Also, stories structurally from reports: featured episodic frames as a result, conveyed...

Abstract Unmanned aircraft systems (UAS) offer a fresh opportunity to teach students the engineering design process (SEDP) and basic principles of aerospace engineering. The widespread popularity UAS, explosion affordable capable systems, recent advances in policy by FAA have enabled climate where UAS may be effectively used as model for many age groups learn SEDP critical problems solving skills. A focused project provides stimulating hands-on active learning are seeking today. In addition,...

Background Evidence shows relaxation techniques reactivate the parasympathetic nervous system (PNS) following physiological stressors such as exercise. As such, these may be useful exercise training of high intensity sports, like collegiate football. Purpose To evaluate impact mindfulness and rest activities on PNS reactivation sessions, in a sample Division-I collegiate, male football athletes. Methods This study employed cross-sectional, pre-post experimental design among 38 Following...

Abstract Pipelines in the Arctic must contend with a variety of geotechnical obstacles affecting their construction and long-term operation. For example, thawing permafrost leads to unstable terrain, especially on slopes pipeline river crossings. Research funded by US Department Transportation is underway investigate how unmanned aircraft systems (UAS) could be used monitor soils order develop proactive decision-support system for operators. Leading this research University Alaska Fairbanks...

A conventional microwave oven magnetron is combined with a ferrite circulator to create high-gain phase-locked amplifier independent control of frequency and power output. The intended application for electronically-steerable phased arrays wireless transmission.

A conventional microwave oven magnetron may be converted into a high gain amplifier with independent frequency, phase and amplitude control. From this building block, phased array for wireless power transmission constructed. Using the design approach detailed herein, steerable beam was demonstrated at UAF in June 1998.

Over the past decade unmanned aircraft systems (UAS) have become increasingly popular, affordable, and technically capable.No longer are UAS considered to be simply for recreation hobby, today's relatively inexpensive offer significant capabilities flight recording of imagery.Combined with easing previously onerous Federal Aviation Administration (FAA) rules governing use commercial/professional purposes, these platforms now provide a viable option scientists engineers apply as tools conduct...

Abstract Aerospace engineering has seen a resurgence in popularity recent years, with major advancements being made across broad spectrum of space exploration and technology. This interest spans various age groups professions, from school students participating science fairs to professionals the aerospace industry. NASA's efforts returning moon visiting Mars have redoubled our youth for learning about rocketry, satellites, related technologies. Likewise, success private companies like SpaceX...
