Multi-scale Modeling Approach to Acoustic Emission during Plastic Deformation

We address the long standing problem of the origin of acoustic emission commonly observed during plastic deformation. We propose a frame-work to deal with the widely separated time scales of collective dislocation dynamics and elastic degrees of freedom to explain the nature of acoustic emission observed during the Portevin-Le Chatelier effect. The Ananthakrishna model is used as it explains most generic features of the phenomenon. Our results show that while acoustic emission bursts correlated with stress drops are well separated for the type C serrations, these bursts merge to form nearly continuous acoustic signals with overriding bursts for the propagating type A bands.Comment: 4 pages, 6 figure

An Analysis Of The Consequences Of Running Away Among Black And Hispanic Female Juvenile Offenders With An Emphasis On Future Orientation

Girls are prominent in the etiology of runaways due to having higher runaway rates than boys. While empirical studies of runaways have extensively focused on the causes of girls’ runaways, few studies shed light on the runaway consequences. Those studies that analyzed the consequences of a girl’s runaway have majorly stressed the delinquent outcomes. However, studies of runaway consequences have minimally paid attention to youth future orientation since future orientation is a vital factor in youth offending behavior. Furthermore, contextual background, such as runaway, influences the same future orientation. Therefore, this research explored the understudied relationship between the girl’s runaway consequences, future orientation, and offending behavior among female Black and Hispanic offenders. This quantitative research utilized a secondary dataset, Research on Pathways to Desistance [Maricopa County, AZ and Philadelphia County, PA]: Subject Measures, 2000-2010 from the Inter-university Consortium for Political and Social Research (ICPSR). This research examined three research questions. The first research question measured whether runaway girls significantly differed in their future orientation, exposure to violence, procedural justice, and certainty of sanctions perceptions than non-runaway girls. The second research question attempted to understand if there are any significant differences between runaway Black and Hispanic girls in their future orientation, exposure to violence, procedural justice, and certainty of sanctions perceptions. The third research question examined the interaction between exposure to violence, procedural justice, certainty of sanctions perceptions, and future orientation’s influence on runaway girls’ offending behavior. This research employed one-way ANOVA and Multiple Regression analysis to analyze the research questions. The research findings from one-way ANOVA identified no significant differences between runaway and non-runaway girls and Black and Hispanic girls in their future orientation, exposure to violence, procedural justice, and certainty of sanctions perceptions. The results from Multiple Regression analysis found a statistically significant influence of the interaction of exposure to violence and future orientation, and procedural justice and future orientation on runaway girls’ offending behavior. Keywords: runaway girls, future orientation, exposure to violence, procedural justice views, certainty of sanctions perceptions, self-reported offending behavio

Land use / land cover change detection analysis through geospatial technology in Jhansi district of Bundelkhand region

The term Land Use relates to the human activity associated with specific of land for example areas under settlement, agriculture, forest, vegetation etc. The cumulative pressure on land for food and wood, the natural balance of soil and environment is affected by deforestation activities which causes serious problem of land degradation. The present study is focused on the changing Land Use / Land Cover practices. “These land use and land cover data are very important for land resource management, planners, and decision makers” (Ndukwe, 1997). In this study has been studied Land use / Land cover change detection of Jhansi district over a period of 12 years. Landsat TM and Landsat ETM + data from U S Geological Survey (1996, 2008) and Survey of India toposheets (2006) have been used for the delineation of classes and district boundary. A study of spatial and temporal changes in Land use / Land cover (LULC) is conducted using Remote Sensing and GIS techniques. ArcGIS 9.3 and ERDAS Imagine 9.2 interface were used for preparing LULC and change detection. The study area is categorized into eight foremost LULC classes viz., built-up land, cropland, fallow land, dense forest and open forest, barren land, sandbar, water bodies. Land use / land cover is very important aspects of land management and development planning of any region. There for, it has broadly been explained and considered as a very imperative element of physical input for agricultural development and land use sustainability.   Bundelkhand, Land Use / Land Cover, Sustainability and Geospatial Technology

Implementation of fuzzy logic controller for load frequency control in two area power system

Currently as there has been an increase in the interconnected systems as far as power systems are concerned. Load as well as power flow in tie-line are varying dynamically. So there is a need of robust control of system frequency as well as tie-line power flow system. This robust control could be achieved by the help of fuzzy logic controllers in the place of orthodox system using proportional, PI and PID controllers. This is due to fact that gain constants in the case of conventional controllers remain same throughout, for changes in the load value. But Load can’t be the same throughout, load deviates from time to time. So as to get rid of these disadvantages related to conventional controllers, a lot many schemes have been put forth in literature. With regard to this work, fuzzy logic base controller has been considered for problems pertaining to load frequency control. There queried rules are carried out with respect to the variation in load to diminish the error. In fuzzy logic controller, we take the help of triangular membership function in the formulation of the rule base, because triangular membership function gives easy way to make the rule base compared to other membership functions. Then simulation is done by using Matlab/Simulink software

Controlled Secret Sharing Protocol using a Quantum Cloning Circuit

We demonstrate the possibility of controlling the success probability of a secret sharing protocol using a quantum cloning circuit. The cloning circuit is used to clone the qubits containing the encoded information and {\em en route} to the intended receipients. The success probability of the protocol depends on the cloning parameters used to clone the qubits. We also establish a relation between the concurrence of initially prepared state, entanglement of the mixed state received by the receivers after cloning scheme and the cloning parameters of cloning machine.Comment: This is a modified version of the previous work quant-ph/arXiv:1011.286
