The high accuracy that can be achieved in the experimental determination of flow parameters from data collected with advanced 4π detection systems has recently been demonstrated in a combined analysis of INDRA and FOPI data [1]. Excitation functions for directed and elliptic flow in Au + Au reactions, measured at SIS by the two collaborations [2, 3], were found to agree within 5% to at most 10%...
We give a detailed and easily accessible proof of Gromov’s Topological Overlap Theorem. Let X be a finite simplicial complex or, more generally, a finite polyhedral cell complex of dimension d. Informally, the theorem states that if X has sufficiently strong higher-dimensional expansion properties (which generalize edge expansion of graphs and are defined in terms of cellular cochains of X) the...
There has been an increase in the study of discrete simulation projects; however, literature lacks the topic of effectively managing these projects. Therefore, in this research, some principles from project management were applied in a discrete event simulation project. The action research method was used to implement the study. The ten knowledge areas from PMBOK®'s (2013) project management th...
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...
This article critically reviews the literature that examines the anxiety phenomenon in the field of second/foreign language learning. A major theme that runs through this review is how anxiety comes into play in second/foreign language learning, and whether it is a central construct or only an add-on element that is negligible. Anxiety is defined and described in how it is measured and relates ...
In real-world applications, it has been often observed that class imbalance (significant differences in class prior probabilities) may produce an important deterioration of the classifier performance, in particular with patterns belonging to the less represented classes. This effect becomes especially significant on instance-based learning due to the use of some dissimilarity measure. We analyz...
Niche overlap is increasingly used as a way of measuring the intensity of interorganizational competition. This paper examines and compares various distance and cosine measures of niche overlap. The analysis in this paper shows that Euclidean distance applied to the raw data as well as to transformed data is not an appropriate measure of niche overlap. An alternative measure from the cosine fam...
