This paper presents bridgeless power factor correction circuits that achieve both high reliability and high efficiency. In electric equipments, using power factor correction (PFC) technology can increase power factor, reduce harmonic pollution on grid and improve power utilization. Rectifier Bridge is commonly used to realize AC to DC conversion in PFC topology and PFC stage realizes power factor correction function. With power level's improving, the loss of bridge rectifier occupies a large proportion in the whole power stage loss. Bridgeless Boost PFC omits Rectifier Bridge by decreasing conduction loss and improves efficiency. This paper introduces the principle of operation including the control scheme and verified performance based on simulation and experimental results.

Carbon emitted on account of our continued use of fossil fuel can be offset using carbon capture and storage (CCS). The technology for this exists, but the economics of it is context dependent, and CCS has shown itself to be not very cost effective in oil sands. Committing to the large-scale sequestration projects needed without properly considering alternatives can prove costly at both the economic and social levels. Charcoal sequestration, discussed earlier by Gupta (2010), provides a few advantages, such as being less costly and lacking any post-operation liabilities. Above all, it is reversible, allowing flexibility of policy and operation and avoiding long-term or large-scale commitments. The economics of the charcoal approach mainly depend on two factors - the cost of the feed biomass and the cost of processing. The first of these is addressed by using municipal waste as feedstock, which can be available free of charge. Expectedly, the cost of processing, the second factor, depends on the apparatus and the scale of operation. In this paper, the authors discuss the benefits and drawbacks of prominent traditional and modern apparatus used for conversion of biomass to charcoal and describe a simple and pragmatic apparatus that could be assembled relatively easily for a small-scale operation such as processing industrial-camp-generated solid organic waste. Offsetting carbon in this manner obviously can be a good way to initiate demonstration projects for the charcoal-sequestration approach because it also helps with waste management. These demonstration projects in turn will help evaluate various aspects of this novel method of sequestration and enhance public awareness on the subject, which in turn will help society make an informed choice to embark on a correct course of action for atmospheric carbon abatement. Additionally, in light of the growing per capita waste worldwide, use of municipal waste as feedstock for charcoal sequestration can be a significant measure of carbon offset at global scale in its own right.

High-bandwidth (16 GHz) time-resolved charge-collection measurements for heavy-ion irradiation of up to 70 GeV/amu are performed on low-power 6.1 lattice spacing InAlSb/InAs HEMT devices. Event cross sections are measured to be significantly larger than the active areas of the devices. Novel energy-dependent effects are observed. © 2010 IEEE.

Presence: Teleoperators and Virtual Environments | Year: 2010

Brain-computer interfaces (BCIs) are becoming more and more popular as an input device for virtual worlds and computer games. Depending on their function, a major drawback is the mental workload associated with their use and there is significant effort and training required to effectively control them. In this paper, we present two studies assessing how mental workload of a P300-based BCI affects participants' reported sense of presence in a virtual environment (VE). In the first study, we employ a BCI exploiting the P300 event-related potential (ERP) that allows control of over 200 items in a virtual apartment. In the second study, the BCI is replaced by a gaze-based selection method coupled with wand navigation. In both studies, overall performance is measured and individual presence scores are assessed by means of a short questionnaire. The results suggest that there is no immediate benefit for visualizing events in the VE triggered by the BCI and that no learning about the layout of the virtual space takes place. In order to alleviate this, we propose that future P300-based BCIs in VR are set up so as require users to make some inference about the virtual space so that they become aware of it, which is likely to lead to higher reported presence. © 2010 by the Massachusetts Institute of Technology.

Gtec | Date: 2012-01-04

A local exhaust system includes a motor provided in an exhaust pipe to generate a rotary drive force when power is applied thereto, in which air is taken in through an intake port and exhausted through the exhaust pipe, a rotor structure disposed on the leading end of the intake port and connected to a drive shaft of the motor, the rotor structure rotating about a central portion of the exhaust pipe, and a plurality of turbulence-generating outer blades for generating a turbulent flow when rotated. Each of the turbulence-generating outer blades is assembled to the outer surface of the rotor structure via an angle-adjusting member in such a fashion that the angle of the turbulence-generating outer blade is adjustable with respect to the direction in which air is taken in through the intake port.
