  • In this study, the results relating to a plasma state which takes into account the ionization instability of non-equilibrium seeded plasma is added to the theoretical prediction of the relationship between enthalpy extraction and isentropic efficiency. As a result, the electron temperature, which reaches the seed complete ionization state without the growth of ionization instability, can be realized at a relatively high seed fraction condition.

  • The implemention of inlet swirl is possible to maintain a low static pressure inside the channel and the enthalpy extraction ratio rises due to the increase of Hall parameter. In addition, the channel cross-sectional area ratio increases due to the swirl implementation, the static pressure is kept low, and the channel inlet flow velocity increases. This also leads to the increase of enthalpy extraction ratio, that is the increase of output power.

  • East and Southern Europe), India, parts of South America, Southwest U.S./northern Mexico and Australia. The operating characteristics of STPPs are relatively well matched with the intermediate and peak electricity load requirements in these regions. Two types of collectors have been used in STPPs: parabolic trough and central receiver. Electricity is generated by incorporating the solar collectors with a Rankine cycle power plant or as an add-on to a natural gas combined cycle (referred to as an ISCCS).

  • Today’s wind energy industry is at a crossroads. Global economic instability has threatened or eliminated many financial incentives that have been important to the development of specific markets. Such economic sponsorship of energy generation is not unique to renewables; fossil based sources are also subsidized in many different countries. However, for a technology like wind energy whose markets are still developing, incentives can be critical for industry growth.

  • An integrated gasification process was developed for an Ohio-based kraft pulp mill to produce liquid transportation fuels from biomass and coal. Black liquor byproduct from the pulp mill is co-gasified with coal to generate high quality syngas for further synthesis to dimethyl ether (DME) and/or Fischer-Tropsch fuels. A Texaco gasifier was chosen as the focal point for this design. Whenever possible, energy is recovered throughout to generate heat, steam, and power. Mass and energy balances were performed for individual process components and the entire design.

  • Previous approaches to pronominalization have largely been theoretical rather than applied in nature. Frequently, such methods are based on Centering Theory, which deals with the resolution of anaphoric pronouns. But it is not clear that complex theoretical mechanisms, while having satisfying explanatory power, are necessary for the actual generation of pronouns. We first illustrate examples of pronouns from various domains, describe a simple method for generating pronouns in an implemented multi-page generation system, and present an evaluation of its performance. ...

  • In this study, a Faraday type MagnetoHydroDynamic (MHD) generator is studied to consider the effect of electrical characteristics to the thermal efficiency. The generator performance is specified by optimizing the cycle efficiency with respect to the load parameter and by optimizing output power density with respect to seed fraction and operating pressure.

  • The control rod assembly controls reactor power by adjusting its position during normal operation and shuts down chain reactions by its free drop under scram conditions. Therefore, the drop performance of the control rod assembly is important for the safety of a nuclear reactor. In this study, the drop performance of the conceptually designed control rod assembly for the prototype generation IV sodium-cooled fast reactor that is being developed at the Korea Atomic Energy Research Institute as a next-generation nuclear reactor was experimentally investigated.

  • In order to produce the high beam power from electron linear accelerator, a proper beam current is required form the electron generator. In this study, the beam current was measured by evaluating the performance of the electron generator. The beam current was determined by five parameters: high voltage at the electron gun, cathode voltage, pulse width, pulse amplitude, and bias voltage at the grid.

  • Draught animals are major source of motive power for majority of farmers. In India bullocks, buffaloes, camels, horses, mules and donkeys are common draught animals. These animals perform different field operations and are also used for rural transportation. In Indian agriculture, bullock farming operations are being carried out by small and marginal farmers and bullock power play an important role in many works. The availability of electric power in rural areas is a serious problem.

  • In this paper we study how power line communications are affected by different coding techniques. We investigate the case of LDPC coding scheme and its application to the PLC channel. The modulation method applied is BPSK while the transmission technique used is OFDM. We study regular LDPC codes, which is the worst case scenario concerning the performance of LDPC codes. The OFDM symbol size is initially defined at 4096 carriers, since certain characteristics of LDPC codes, like their sparse parity check matrix, imply that a larger block size improves their performance.

  • Conflict is a part of life that many of us tend to avoid and fear. Traditional schooling gives us little training to handle conflict, and most of us have poor role models from which to learn. Despite the lack of attention we give it, conflict has the power to destroy self-esteem, relationships, and even corporations. Conversely, it also has the power to generate creativity, better solutions, next-level thinking, and passionate results. Conflict when handled poorly is incredibly destructive. Conflict when handled well turns mediocre businesses into stellar corporations...
