GA tuning of pitch controller for small scale MAVs

The paper presents the application of intelligent tuning methods for the control of a prototype MAV in order to address problems associated with bandwidth limited actuators and gust alleviation. Specifically, as a proof of concept, the investigation is focused on the pitch control of a MAV. The work is supported by experimental results from wind tunnel testing that shows the merits of the use of Genetic Algorithm (GA) tuning techniques compared to classical, empirical tuning methodologies. To provide a measure of relative merit, the controller responses are evaluated using the ITAE performance index. In this way, the proposed method is shown to induce far superior dynamic performance compared to traditional approaches

Teacher education for inclusive practice – Responding to policy

This article draws on research on the way in one teacher education in England and examines the ways in which the programme prepares student-teachers for inclusive practice in science teaching. We frame our analysis by drawing on aspects of institutional mediation of official policy in teacher education programmes, we need pedagogies of praxis that move beyond (and sometimes against) the official policy definitions of inclusion, and draw instead on a more critical approach to the formation of future professionals.http://www.tandfonline.com/doi/full/10.1080/02619768.2015.1031338http://www.tandfonline.com/doi/full/10.1080/02619768.2015.103133

Information theory in the study of anisotropic radiation

Information theory is used to perform a thermodynamic study of non equilibrium anisotropic radiation. We limit our analysis to a second-order truncation of the moments, obtaining a distribution function which leads to a natural closure of the hierarchy of radiative transfer equations in the so-called variable Eddington factor scheme. Some Eddington factors appearing in the literature can be recovered as particular cases of our two-parameter Eddington factor. We focus our attention in the study of the thermodynamic properties of such systems and relate it to recent nonequilibrium thermodynamic theories. Finally we comment the possibility of introducing a nonequilibrium chemical potential for photons.Comment: 1 eps figure upon request by e-mail, to appear in Journal of Physics

Health Link for Pharmacist-led Public Health Programmes in Zimbabwe: Developing education pathways through partnership.

Background. Forming collaborations and partnerships across borders is a principal componenet of transnational education practice. One approach to establishing transnational partnerships is to form alliances based on best-practice. Pharmaceutical public health education and training and the delivery of pharmaceutical services with a public health message is an area where transnational approaches can be fostered. Objectives The objective of the project was to establish a partnership (Health Link) between the pharmacist professional bodies of Zimbabwe and Great Britain in order to develop the capacity and capabilities of pharmacists in Zimbabwe to deliver public health programmes. Methods The process involved partner selection and engagement, as well as engagement with a range of stakeholders. The methods of engagement involved partners’ meetings, a field visit to Zimbabwe for discussions with relevant stakeholders, a feedback workshop and dissemination activities. The set indicators of success were: agreed aims and objectives, agreed work streams, and establishment of a Memorandum of Understanding (MoU). Outcomes The project was successfully implemented with two of the three indicators of success (agreed aims and objectives and agreed work streams) achieved. A formalized Memorandum of Understanding is now being developed across the partner organizations, which forms the basis of a formal transnational approach to developing pharmaceutical public health education in Zimbabwe

Economic Contributions of Mega-Dam Infrastructure as Perceived by Local and Displaced Communities: A Case Study of Merowe Dam, Sudan

No embargo required. Investigations on the socioeconomic impacts of mega-dam projects have tended to focus on conventional cost–benefit analysis, while studies exploring perceptions of local communities, who are some of the prime beneficiaries of these development initiatives, are limited. This paper aims to address this research gap through a case study of community perceptions on the socioeconomic impacts of the Merowe Dam in Sudan from the residents of upstream, downstream, and relocated locations. Data were collected primarily through surveys and interviews with residents, government officials, dam implementation authority, non-governmental organizations (NGOs) and other key informants and a series of indicators were developed for the analysis from the responses. Three inter-related areas of impact were scrutinized: (a) electricity generation; (b) development of modern agriculture; and (c) institutional infrastructure in the region. The results reveal that local communities are fully aware of both the positive and adverse socioeconomic impacts of the Merowe Dam, although these are focused more on the visible impacts closely related to their livelihood and income, such as increased food production, water shortages, electricity supply and its costs. Policy implications include investments in the new settlement areas with respect to the agricultural economy, such as irrigation improvement through electrification, promoting crop diversity, research, development, and diffusion of modern agricultural technologies. Efforts are also needed to strike a balance between provision of utilities and services, (i.e., water, electricity and other infrastructural facilities) provided by the Merowe Dam, amongst communities in relocated, upstream, and downstream locations.</jats:p

Nonequilibrium corrections in the pressure tensor due to an energy flux

The physical interpretation of the nonequilibrium corrections in the pressure tensor for radiation submitted to an energy flux obtained in some previous works is revisited. Such pressure tensor is shown to describe a moving equilibrium system but not a real nonequilibrium situation.Comment: 4 pages, REVTeX, Brief Report to appear in PRE Dec 9
