Line-transect estimates of abundance generally assume that distances and angles to animals are measured without error. Biased distance measurements will lead to corresponding bias in abundance estimates. Efforts to address this have been made, but measuring distance to cetaceans at sea remains problematic. Four distanceestimation experiments were conducted to explore relationships between estim...

Chemical structures of organic compounds are characterized numerically by a variety of structural descriptors computed either from the molecular graph or from the three-dimensional (3D) molecular geometry. Extensive use of such structural descriptors or topological indices has been made in drug design, screening of chemical databases, similarity and diversity assessment, and quantitative struct...

Abstract Creep response for isotropic axisymmetric rotating disc made of a particle-reinforced FGM has been investigated in the present study. The result obtained for non linear variation of particle distribution along the radial distance of the disc are compared with that of discs containing the same amount of particle distributed uniformly or linearly along the radial distance. The disc under...

This paper examines the problematization of cultural issues related tothe dual spacization of life. The emergence of the second space of lifeover the first place of life combining local and translocal, national andtransnational capacities and challenges. We discuss the capacities andopportunities occurring through the instant communication industrywhich made the spontaneous connection between a...

Fashion and mode among the youth is a kind of social values and trends. Parentship conflict and generation gap make a great distance between parents and children. This paper tries to study the high school girls attitudes toward fashion in Minab. The present survey uses theories frameworks like, Bourdiou, Zimel and Veblen. More than 312 high-school girls were analyzed as sample group in Minab. T...

De novo structure determination of proteins is a significant research issue of bioinformatics. Biochemical procedures for protein structure determination are costly. Use of different pattern classification techniques are proved to ease this task. In this article, the secondary structure prediction task has been mapped into a three-class problem of pattern classification, where the classes are h...

Hierarchical clustering method is used to assign observations into clusters further connected to form a hierarchical structure. Observations in the same cluster are close together according to the predetermined distance measure, while observations belonging to different clusters are afar. This paper presents an implementation of specific distance measure used to calculate distances between obse...

STP-BV is a bounding volume made of patches of spheres and toruses. These patches are assembled so that a convex polyhedral hull is bulged, in a tunable way, into a strictly convex form. Strict convexity ensures at least C property of the distance function –and hence, its gradient continuity. STPBV were introduced in our previous work [1], but proximity distance queries were limited to pairs of...

This study examines the effects of background noise, actual source distance, and room reverberation on the perceived distance of a single phrase of recorded speech reproduced at a naturalistic sound pressure level. A simple rectangular room was used for stimulus generation, wherein binaural recordings were made with source-receiver distances between 0.9 m and 5.1 m, reverberation times between ...
