The synthesis, processing, and device performance of polymeric semiconductors has been reported. The polysilicon TFT technology is used for active matrix organic light-emitting diode (AMOLED) as the higher carrier mobilities of polysilicon as compared to a-Si, and increased stability of polysilicon-based devices under bias stress, are more effective in AMOLED. The radio frequency (RF) wireless applications are required in large area, self-powered, or maximized range device is partially driven by the fundamental physics of the frequency regimes in which they operate. Large area, high throughput manufacturing of organic electronic roducts is most efficiently enabled by solution based, additive printing techniques. Regioregular (RR) poly(3-hexylthiophene) (P3HT) is an exemplary semiconducting polymer due to its ready availability, ease of processing from solution, and its promising electrical properties arising from a highly crystalline microstructure.

A major driver to project success is the ability to manage the project cost effectively. Despite the agreement among scholars and practitioners on the importance of managing the project cost, excessive cost overruns continue to occur on major power transmission projects. In this paper, the author, through a Delphi method, will discover problems of managing the project cost, suggest solutions to overcome these problems, and identify lessons learned from these projects. The study was conducted with two different project teams in the same organization in Canada. Key findings from this study will highlight similarities and differences between the two cases in terms of how each team managed the project cost and learned from it. The paper will contribute to the body of knowledge by identifying lessons learned from power transmission projects on how to manage the project cost and by suggesting solutions to overcome the problem of cost overrun in these projects. © 2013 American Society of Civil Engineers.

To satisfy the increasing demands in computing throughput, new processor designs are frequently expanding their support for parallel operations, including multiple memory controllers, caches, and various I/O devices, but especially multiple processor cores. For developers of real-time embedded systems with security and/or safety-critical computing requirements, the advent of processors that include multiple cores has created a fundamental problem: how to satisfy certification considerations so that safety and/or security related applications can execute on real-time multi-core based partitioning enforcing systems. © 2013 IEEE.

This paper focuses on the institutional dynamics of family-led organic farms in the mountains of Nepal. It is based on continuous observations and experiences of local farmers who have dedicated themselves to organic agriculture for a significant period of time. It is found that family-led organic farming can contribute significantly to the sustainable use of local agricultural resources. The family, as an autonomous institution, is found to be effective for governance of local agricultural resources by transferring indigenous knowledge systems and traditional farming technologies to successive generations. We realised that it is most important to recognise local processes that govern the use of agricultural resources and local innovations that augment the practices of organic farming. It is concluded that family farms in mountainous regions of Nepal should be developed as an important sector of agriculture by enacting sound policies for local agricultural resources governance, empowering regional development bodies, and strengthening local market.
