The paper provides an overview of the development and operational deployment of the Traffic alert Collision Avoidance system (TCAS). TCAS was one of the first software based “safety of life” systems deployed in aircraft.

background: pistachio is a plant that has long been cultivated in different parts of iran. pistachios are very nutritious and contain vitamins e and b, flavonoids, antioxidants, and carotenoids. since the pistachio is effective in the treatment of some neurological disorders and is indigenous to iran and considering the substantial use of this nut, it is necessary to investigate its effects on ...

Abstract This paper presents the robust detection of interturn short circuit fault double redundant permanent magnet synchronous motor. In static coordinate system and dq-axis system, mathematical model state is established. Further, residual signal current caused by turn-to-turn predicted using Luenberger observer. Next, marker phase are obtained processing signal. Finally, processor performs ...

Avoidance is a key characteristic of adaptive and maladaptive fear. Here, we review past and contemporary theories of avoidance learning. Based on the theories, experimental findings and clinical observations reviewed, we distill key principles of how adaptive and maladaptive avoidance behavior is acquired and maintained. We highlight clinical implications of avoidance learning theories and des...

213 news & views time to useful timescales. By manipulating the ratio of these modified monomers, Rant and co-workers created nanopores that contained only a single nitrilotriacetic acid group within the sensing zone of the nanopore, which could be used to detect the reversible binding of single proteins. In another part of the study, Rant and colleagues functionalized a nanopore with three nit...

objective(s): auraptene (7-geranyloxycoumarin) (aur), from citrus species has shown anti-inflammatory, neuroprotective, and acetylcholinesterase (ache) and beta-secretase inhibitory effects. scopolamine is a nonselective muscarinic receptor antagonist which causes short-term memory impairments and is used for inducing animal model of alzheimer’s disease (ad). this research aimed to investigate ...
