We describe a method to detect buildings and construct 3-D shape descriptions of the buildings from a monocular aerial image of general viewpoint. A grouping process is used to generate 2-D roof hypotheses from fragmented linear features extracted from the input image. Good hypotheses are selected based on 2-D evidence and some local 3-D evidence. These are then verified by searching for 3-D ev...

あらまし シングルキャリア(SC)伝送に最小平均二乗誤差規範に基づく周波数領域等化(MMSE-FDE)を用いれば, 周波数選択性フェージング環境下で優れた伝送特性が得られる.FDE では,ブロック間干渉(IBI)を避けて受信信号 を送信信号とチャネルインパルス応答の巡回畳み込みとするために,チャネルの最大遅延時間以上のサイクリック プレフィックス(CP)をガードインターバル(GI)に挿入になければならないので,伝送効率の低下を招いてしまう. CP 挿入を行わずに IBI を低減する技術として Overlap FDE と IBI キャンセラがある.本論文では,CP 挿入を行わな い SC 伝送における Overlap FDE と IBI キャンセラのビット誤り率(BER)の特性比較を計算機シミュレーションによ り行っている. キーワード Overlap FDE,IBI キャンセラ,シン...

introduction: determining the overlap rates is a quantitative method to compare database contents. in this survey, traditional overlap, relative overlap and synthetic degrees of freedom between pubmed as a free database and scopus as a subscription-based one in the cardiovascular disease field have been determined. methods: this descriptive applied research was done during january to june 2009....

Abstract ADAPT-VQE is a robust algorithm for hybrid quantum-classical simulations of quantum chemical systems on near-term computers. While its iterative process systematically reaches the ground state energy, practical implementations are sensitive to local energy minima, leading over-parameterized ansätze. We introduce Overlap-ADAPT-VQE grow wave-functions by maximizing their overlap with any...

We calculate the 1-loop renormalization of the fermion self-energy, all local fermion bilinears, as well as a set of extended bilinears which form a basis corresponding to moments of the parton distribution functions. We use the overlap action for fermions and Symanzik improved action for gluons. Our results are presented as a function of the overlap parameter ρ and the parameters entering the ...

Many realistic planning problems (such as those in manufacturing) place a high premium on plan efficiency. However, classical planning theory does not offer much insight into ways of obtaining efficient plans. The objective of this paper is to present a model of planning for plan efficiency that has been drawn from a case study in the machining domain. Some of the important features of this dom...

The finite field Kakeya problem deals with the way lines in different directions can overlap in a vector space over a finite field. This problem came up in the study of certain Euclidean problems and, independently, in the search for explicit randomness extractors. We survey recent progress on this problem and describe several of its applications.
