This Account outlines the recent efforts of developing catalysis under the ambient conditions of air and water for synthetic purposes from the author's laboratory. The discussions are focused on catalytic reactions (mostly C-C bond formations) other than oxidations via late transition metals. It includes the following aspects: (1) copper-catalyzed C-C bond formations; (2) palladium-catalyzed C-...

This paper is concerned with rigid formations of mobile autonomous agents using a leader-follower structure. A formation is a group of agents moving in real 2or 3dimensional space. A formation is called rigid if the distance between each pair of agents does not change over time under ideal conditions. Sensing/communication links between agents are used to maintain a rigid formation. Two agents ...

objectives: social capital is a concept developed in sociology an also used in business, organizational behavior, political science and economics. in this article the process of social capital formation in a sample of university students is reported. method: to develop an empirical model, we have assumed that individuals have two kinds of sources to form their social capitals: “identity sources...

the kalut-e-ashrafa area is located in the north-east of ardakan area in central iran, yazd province. this area promises copper mineralization. the most of the minerals in this study area are silica-rich veins and veinlets. therefore, in order to identify geological formations with silica zones and to determine potential mineralization areas, aster images and remote sensing methods were used. a...

the present study was carried out to determine the possible origins of sediments entering taleghan dam in northern part of iran, in order to avoid further sedimentation and helping in extension of the useful life of the proposed dam. this was performed by xrd analysis. to do so, first of all, sediment sampling points were positioned along the taleghan river. the collected samples, after coding,...

Given a pair of keyframe formations for a group consisting of multiple individuals, we present a spectral-based approach to smoothly transforming a source group formation into a target formation while respecting the clusters of the involved individuals. The proposed method provides an effective means for controlling the macroscopic spatiotemporal arrangement of individuals for applications such...
