guidance and control of aircraft in the landing phase imposes extra pilot work loads, hence application of automatic landing control systems is of great importance. in this study automatic landing control systems are introduced and an optimal landing control system is designed. the control system performance criteria are based on minimum control effort. the designed system is simulated for a tr...

psychometric properties of automatic thoughts questionnaire and investigation of the relationship between automatic thoughts with cognitive emotion regulation and self regulated learning
To guarantee the success of massive multiple-input multiple-output (MIMO), one of the main challenges to solve is the efficient management of pilot contamination. Allocation of fully orthogonal pilot sequences across the network would provide a solution to the problem, but the associated overhead would make this approach infeasible in practical systems. Ongoing fifth-generation (5G) standardisa...
あらまし 次世代移動無線通信では超高速パケットアクセスが主流になり,誤り訂正符号化と自動再送要求 (ARQ)を組み合わせたハイブリッド ARQ(HARQ)が重要な技術になると考えられる.直接拡散符号分割マルチアク セス(DS-CDMA)を対象に,平均 2 乗誤差最小(MMSE)規範に基づく周波数領域等化(FDE)を用いることで,よく知ら れた Rake 合成受信よりも優れた伝送特性が得られることが示されている.FDE を用いる場合にはブロック間干渉 (IBI)を避けるためにガードインターバル(GI)の挿入が必要であるが,これは伝送効率の低下を招く.そこで最近, GI の挿入を必要としないオーバーラップ FDE が提案された.筆者らは以前,オーバーラップ FDE を用いる DS-CDMA HARQ のスループット特性を明らかにしたが,これまでの検討では理想チャネル推定を仮定していた. ...
Using scanning harmonic radar, we make visible for the first time the complete trajectories of "goal-vector" flights in honeybees. We demonstrate that bees captured at an established feeding station, and released elsewhere, nevertheless embark on the previously learned vector flight that would have taken them directly home from the station, had they not been artificially displaced. Almost all o...
G-induced loss of consciousness (G-LOC) is a pilot human factors (HF) problem that plagues all air forces that fly high performance fighter aircraft. Spatial disorientation (SD) is an even more serious HF problem that affects not only the military but also commercial aviation. By some estimates, one out of every four aircraft mishaps is due to a HF problem, and the pilot flies a perfectly opera...
