The handling of rape by the criminal justice system may be intimately intertwined with the gender inequality found in patriarchal communities. The present study examined the empirical relationship between female sociopolitical power and the rape rates and rape case clearance rates of 105 counties in an agrarian state with a reputation for patriarchal culture. The results suggested that, after controlling for contextual variables, counties with higher levels of female sociopolitical power also experienced higher rates of rape, and lower proportions of rape cases cleared by an arrest. The findings suggested that women in patriarchal communities experience a backlash effect as they achieve progress toward gender equality. © The Author(s) 2013.

Employee organizational commitment provides positive outcomes for any organization, including law enforcement agencies. Although organizational characteristics such as supervisor feedback and organizational support have a strong influence on increasing organizational commitment in other sorts of organizations, the police organizational environment is unique and can hamper the facilitation of these characteristics. The present study used a sample of police officers to test the influence of supervisor feedback and perceived organizational support on officer organizational commitment, net the influence of other organizational, job characteristic, and officer personal characteristic influences. The findings revealed that, in spite of the barriers faced by police managers, these characteristics and other organizational-level characteristics were strong predictors of officer organizational commitment. © The Author(s) 2012.

The aerodynamic performance of two open fan configurations for Fan-In-Wing system applications is investigated and compared using Computational Fluid Dynamics analysis. Two open fan configurations based on NACA64-212 and NACA0012 platforms are investigated, where the first fan is modeled three different blade twists and the second fan operates at three different rotational speeds. Aerodynamic characteristics and hover performance are evaluated for both open fans over a range of collective angles. Numerical simulations indicate that the blade twist has a significant impact on the formation of laminar and turbulent boundary layers on the fan surface, and each blade twist is associated with an optimal rotational speed to achieve the best hover efficiency. Computational results for the NACA0012 open fan are validated with the wind tunnel test data, indicating that thrust and power characteristics of open fan has been correctly predicted using the current turbulence modeling methods. © 2016, American Institute of Aeronautics and Astronautics Inc, AIAA.

Several works have been done to design a simulation testbed for unmanned aerial vehicles (UAVs) in order to simulate the UAV Network (UAVNet) in a cost-effective manner. Our previously developed UAVSim is one of those attempts and has the capability of simulating large UAV networks as well while giving detailed results in terms of mobility modeling, traffic measurements, attack analysis, etc. The usefulness of such a simulation testbed cannot be guaranteed unless it is hardware independent. Therefore, we present a performance evaluation of such a recently developed software simulation testbed, UAVSim, using traditional and generic hardware available in any regular computer laboratory, in order to show its usefulness in an academic research setup. We show performances for two different environments for two separate machines. Results show that the simulation time is quite predictable and reasonable for a particular network size. © Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2014.

With the rapid development of smart home, it becomes essential to study techniques to safeguard the home area network (HAN) against various security attacks. In this paper, a smart home network simulation testbed has been developed for security research in this area. It is designed to feature high fidelity, cost-effectiveness and user-friendliness. The testbed enables users to specify the HAN network topology, communication protocols and appliances, as well as develop security mechanisms such as information flow tracking. For the evaluation purpose, two security mechanisms were implemented on the testbed and their effectiveness against attacks is studied using the developed testbed. © Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2014.
