The quark mixing matrix with manifest Cabibbo substructure and an angle of the unitarity triangle as one of its parameters Abstract The quark mixing matrix is parameterised such that its " Cabibbo substructure " is emphasised. One can choose one of the parameters to be an arbitrarily chosen angle of the unitarity triangle, for example the angle β (also called Φ 1).
In this paper we consider finding solutions for problems represented using AND/OR graphs, which contain tasks that can fail when executed. In our setting each node represent an atomic task which is associated with a failure probability and a rollback penalty. This paper reports the following contributions (a) an algorithm for finding the optimal ordering of the atomic tasks in a given solution ...
Most of the rainfall in arid and semi-arid regions, which becomes runoff immediately after rainfall, eventually evaporates and becomes inaccessible. Harvesting water from impermeable rock surfaces and storage in reservoirs or aquifer feeding is an effective way to prevent evaporation losses in these areas. The purpose of this study is to model the amount of runoff in sub-basins with impermeable...
Rapid urbanization and growing industrial demand in many developing countries has led to frequent congestion of the transport infrastructure. Therefore, the expansion of high-speed rail (HSR) networks is crucial to meet this growing demand. Nevertheless, applying high cyclic stress causes significant lateral spreading and in turn excessive settlements of the track substructure. This problem bec...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Background and Aim: Investigating the effect of intellectual capital on an organization’s ongoing processes is a way of determining its weaknesses as well as appropriate strategies which help managers to make decisions. The main purpose of this study was to confirm intellectual capitals through improving organizational culture among staff managers of IKRF—deputy for support and health. Materi...
Compact substructure is expected to arise in a starless core as mass becomes concentrated in the central region likely to form a protostar. Additionally, multiple peaks may form if fragmentation occurs. We present ALMA Cycle 2 observations of 60 starless and protostellar cores in the Ophiuchus molecular cloud. We detect eight compact substructures which are > 15 from the nearest Spitzer YSO. On...
cultural iran is a scope that is more extended than the political territories of iran as a political unit. this concept means that cultural geography(mehdi moghanlo-1383-1) of iran is greater than its political geography which, according to history, has a long history extending west-east from kandahar to the euphrates and north-south from the persian gulf to the caucasus including transoxiana a...
pressurized injection operation means the pressurized injection of a liquid or solution into pore of a mass of soil or stone and/ or cavity between them and built structures. the injected mortar mustconstitute a soil and/ or jel- like matter inside the cavites, and/ or the operations of the injection must cause sedimentation of the solid matter suspending in these cavites. the primary purpose o...
