The use of rotor tip-fans for enhancing both power conversion as well as low wind speed operation of wind turbines is investigated. It is proposed that tip-fans operating in the tangential directions create a tangential force that enhances the lift force due to wind. Experiments are carried out in a wind tunnel to investigate the effect of tip-fans on the turbine performance. Furthermore, initial results of wind tunnel testing showed that more net power is extracted from the wind when tipfans are ON than when tip-fans are OFF. It is concluded that the wind turbine performance is greatly affected by tip-fans which enhance the rotor speed at low wind speed. The present experimental results suggest that the performance of the proposed system is considerably greater than that of a bare wind turbine. © 2011 IEEE. Source

Implementing high-quality measurement systems in large test environments presents a number of unique challenges. And, these challenges are made even more interesting where new instrumentation systems are being implemented in existing legacy environments where there is little opportunity to modify the infrastructure. Often, Electromagnetic Interference (EMI) is encountered. This interference may be simply an annoyance when sufficiently low that data integrity is not severely compromised, but in many cases, perhaps most, EMI is so severe as to totally obscure the signals of interest. Various sources of EMI and common points of entry of are reviewed. Means of mitigation of EMI in the design and implementation of instrumentation systems in legacy environments are presented. Common sources of EMI potentially introduced by the instrumentation systems themselves are examined, and means of design to mitigate such self-induced interference are examined. Real-life examples are provided to demonstrate the EMI issues, and the effect of mitigation. It's all about the current - pretty much!. Source

Education for Health: Change in Learning and Practice | Year: 2014

Background: University of New Mexico Health Sciences Center(UNMHSC), located in Albuquerque, New Mexico, USA, has an international reputation for developing and implementing curricular initiatives addressing health inequities. The Street Outreach and Shelter Care elective is designed to provide interprofessional service learning opportunities for senior pharmacy and medical students addressing the needs of our nation's most marginalized population-those experiencing homelessness. Methods: Our institution collaborated with multiple community partners serving the homeless to develop, implement and teach a 4-week senior elective for health professions students. During this elective, senior pharmacy and medical student teams provide individualized health care to men in local homeless shelter facilities. Students also participate in street outreach programs across a continuum of homeless populations. Weekly interprofessional education(IPE) faculty-facilitated sessions allow students to reflect on their experiences and learn from other discipline perspectives. Results: Student evaluations uniformly reflect the transformative nature of the rotation since its inception, April 2009. Our outcomes corroborated the findings of similar service learning models developed to sensitize health professions students to the complex challenges of homeless populations. Discussion: Academic centers can play a central role in health education reform by instituting curricula focusing on the primacy of population welfare and just distribution of resources. Senior year is an opportune time to reinforce social accountability among health professions before graduation. This elective is based on adult principles of learning and can serve as an international educational model for developing interprofessional curricular innovations addressing the healthcare needs of vulnerable populations.

Today micro wind turbines are the most widely used type of wind turbine. The use of rotor tip-fan for enhancing both power conversion as well as low wind speed operation of wind turbines is investigated. It is proposed that tip-fans operating in the tangential directions create a tangential force that enhances the rotor thrust. Experiments were carried out in New Mexico State University wind tunnel to investigate the effect of tip-fans on the turbine performance. Furthermore, initial results of wind tunnel testing showed that more net power is extracted from the wind when tip-fans are ON than when tip-fans are OFF. It is concluded that the wind turbine performance is greatly affected by tip-fans which enhance the rotor speed at low wind speed. The present experimental results suggest that the performance of the proposed system is considerably greater than that of a bare wind turbine. This paper presents developing a mathematical model for wind turbines with tip-fan attached to each blade's tip. © 2013 IEEE. Source

Although school wellness policies have the potential to transform school environments, relatively little has been written about postadoption policy implementation and evaluation (policy to practice). The authors report results of a research study that examined the implementation of school wellness policies in two school districts in northern New Mexico. Through nine key informant interviews with administrators and two focus groups with students, they found that physical activity and nutrition policies were implemented inconsistently in both districts. Study participants identified facilitating factors (e.g., champions, grant funding) and barriers (e.g., competitive food sales, lack of clarity about responsibility for policy enforcement) to policy implementation. Participants also provided recommendations to improve policy implementation, including wellness policy training for school personnel and parents, improving the taste, nutritional value of, and choices in cafeteria food; and involving the community health council to promote community understanding and support of the policies. This study underscores the need to identify and address factors involved in the successful implementation of school wellness policies, looking at schools in the larger context of their communities. It also serves as an example of the potential for communities, schools, and others to work together to address a locally identified health priority. © 2012 Society for Public Health Education.
