Model-Based Design Approach to Predict Performance of BAS/Electric Motor for OSU EcoCAR 3 Vehicle

Engineering and ArchitectureIn today’s society, there is growing concern over the state of the global climate and the impact that we have on it. Scientists and engineers are seeking ways to meet energy demands and emissions regulations around the world by creating more sustainable and energy efficient technologies. In the automotive industry, this can be evidenced by the advent of hybrid electric vehicles. The Ohio State University EcoCAR 3 team based at the Center for Automotive Research is converting a 2016 Chevrolet Camaro into a plug-in hybrid electric vehicle with the end goal of improving fuel consumption and emissions whilst maintaining the performance aspects of the vehicle. The main focus of this research was to model, predict, and improve the performance of the belted alternator/starter (BAS) and electric motors in the vehicle. Research began with gaining exposure to the full vehicle model as well as the component models in the team-developed simulator using MATLAB and Simulink. A higher fidelity model of the BAS was developed based on dynamic equations of the electric machine. Due to inverter calibration constraints, the BAS could not be physically tested during the time of this internship. Nonetheless, testing was done on the traction motor, which can be used to validate already existent models of the component. The vehicle was placed on a chassis dynamometer and run through multiple drive cycles. Data from this testing was logged, analyzed, and compared to results from the simulation. This type of analysis of data such as requested/actual torque, motor speed, temperature, etcetera, can be used to calibrate/validate different aspects of the vehicle and component models. As a result of this research, the vehicle model will be able to run more accurate simulations and increase component and vehicle performance, which will help the team perform well in the EcoCAR 3 competition.OSU College of Engineering Summer Undergraduate Research ProgramAcademic Major: Mechanical Engineerin

Calculation of the number of partitions with constraints on the fragment size

This article introduces recursive relations allowing the calculation of the number of partitions with constraints on the minimum and/or on the maximum fragment size

Investigation of the D and E regions of the ionosphere

Details of an experimental program that investigates the ionosphere using sounding rockets are presented. The investigation is part of a continuing program to gather data on the D and E regions of the ionosphere during periods of recurring natural phenomena that influence these regions. To achieve these ends, four vehicles were launched during the eclipse of the sun on March 7, 1970. Other vehicles totalling 10 in all were launched to investigate transient phenomena such as the sporadic E layer

Effect of state level rabies control policy and terrestrial mammal reservoir on canine and feline rabies cases in the United States

Master of Public HealthPublic Health Interdepartmental ProgramSanjeev K. NarayananRabies is a fatal, encephalitic disease caused by numerous variants of a lyssavirus to which all mammals are susceptible. In the United States, domestic animal rabies prevention and control is subjective to individual state health departments; leading to a wide variety of control policies. This study was conducted to determine whether a correlation could be found between state rabies control policy and the incidence of rabies in canines and felines from 2009 through 2012. In addition, since several terrestrial mammal rabies reservoirs are native to different states throughout the country, an evaluation of relationship between prevalent terrestrial mammal rabies reservoir and the number of rabies positive cases was performed. States were grouped into regions based on the predominant rabies reservoir within state lines to determine if any correlation exists between the number of positive rabies cases in canines and felines and the terrestrial mammal reservoir. A state by state examination of domestic animal rabies control policy was conducted and positive rabies case data for canines and felines from 2009 through 2012 were obtained by contact with state public health representatives and from official state websites. Statistical analysis was performed using a Chi-Squared test for independence. This analysis determined that the number of canines and felines that tested positive for rabies in each state was correlated to the domestic animal rabies control policy utilized and the terrestrial mammal rabies reservoir in that state. These results suggest that renovation of state rabies prevention and control, and reporting policies as well as additional study would provide a more descriptive analysis of the effectiveness of various rabies control policies as well as provide an opportunity to analyze the breadth and depth of the rabies burden and its impact on human health in the United States

En busca del recurso: abordaje económico de nucleamientos indígenas al sur del Conurbano bonaerense

Desde un abordaj e que retoma la articulación entre economía, política y etnici dad, el objetivo del presente trabajo es analizar las formas de organización de comuni dades indígenas urbanas en l a actualidad. La complementación de recursos propios, ayudas estatales y de proyectos colectivos no sólo expresa el manejo de los mi smos sino que mani fiesta una mayor organización, fortalecimiento y vi si bilización étnica en el plano local.Fil: Engelman, Juan Manuel.

City Year: Year 1 Evaluation Report, 2013-2014

City Year is an education-focused nonprofit organization that partners with high needs public schools to enhance the quality of the learning environment in the areas of attendance, behavior, and course performance. This is achieved by deploying teams of City Year corps members to the schools. The expectation is that students who receive support from City Year corps members in the areas of English, math, attendance, and behavior will show growth in their academic and behavioral outcomes. With funding from the William Penn Foundation, City Year is being implemented in 11 high needs public schools within The School District of Philadelphia (SDP or District); targeted support is provided to at-risk students in grades 6 to 9. The Office of Research and Evaluation (ORE) is currently evaluating City Year's effectiveness in meeting the above goals for the 2013-2014 school year (SY) – Year 1— and extending into the 2014-2015 SY – Year 2
