Influence of information processing ability on human information system interaction efficiency

The essentiality of human information system interaction efficiency was analyzed under the computerization environment of enterprises. Information processing ability was measured from three dimensions: working memory, cognitive skill, and computer self efficacy. The experimental method was used to study the influence of information processing ability on human information system interaction efficiency. Multiple regression results show that cognitive skill is the main factor influencing interaction efficiency for skill based tasks, working memory is the main factor for rule based tasks, and working memory has no significant influence on interaction efficiency for knowledge based tasks. Working memory and computer self efficacy are the main factors influencing interaction efficiency for total tasks.

Dynamic optimization design of marine gear transmission system

A dynamic model of transmission system for a marine gear is established considering time-varying mesh stiffness, mesh damping and tooth composite error. The solution efficiency is improved by taking contact line length change of gear pair instead of instantaneous gear mesh stiffness change and making mesh damping and tooth surface equivalent to viscous damping. Multi-objective dynamic optimization design is put into practice to improve the marine gear transmission system using vibration acceleration and mass as target function. The results show that the optimization method can effectively reduce the vibration level and mass of marine gear.

Comprehensive assessment of nutrient management technologies for cauliflower production under subtropical conditions

We developed a methodological protocol for comprehensive evaluation of nutrient management (NM) technologies for production of cauliflower taking its yield, quality, profitability, energy balance and environmental sustainability in terms of soil quality as the goal variables. Fifteen NM technologies comprising three sources of nutrients viz., organics [farmyard manure (FYM), vermicompost (VC) and green manure], inorganic fertilizations (recommended NPK at the rate of 200-44-82 kg ha⁻¹and 125% of recommended NPK) and their selected combinations were tested for producing cauliflower for six consecutive growing seasons during 2006–2011. Integrated NM technology proved to be economically sound and environment-friendly practice. It helped to produce better quality cauliflower with higher value added products such as crude protein, dietary fibre, and vitamin C. Further, it concomitantly maintained better soil quality by improving soil organic carbon stock, microbial biomass carbon, bulk density and extractable plant available nutrients. Combining all the parameters together by employing non-parametric evaluation of regression factor scores through principal component analysis, the NM technology of FYM 5 Mg ha⁻¹ + 125% of recommended NPK and VC 3 Mg ha⁻¹ + 125% of recommended NPK were found to be the best among the NM technologies compared. The superiority of the technologies were attributed to higher curd biomass yield (8.36 and 9.70 Mg ha⁻¹, respectively), higher economic return (benefit-cost ratio 2.7 and 2.5; marginal rate of return 8.0 and 5.1, respectively), more energy conserving efficiency (net energy 22.4 and 25.7 GJ ha⁻¹; output-input energy ratio 1.86 and 2.00, respectively) and greater improvement in the indices of soil quality (6.219 and 5.709, respectively) and crop quality for human (6.7 and 7.4, respectively) and animal (7.4 and 6.4, respectively) nutrition. Organics were less productive, less profitable, and energetically less efficientas compared to integrated and inorganic systems for cauliflower production in subtropics.     

Dynamic optimization design of gear transmission system for wind turbine

The differential equation which governs the behavior of the gear transmission system of 1.5 MW wind turbine is established. The external excitation caused by wind speed fluctuation is discussed and the internal excitation due to time varying mesh stiffness and comprehensive error is also analyzed. The calculating formulations of the harmonic balance method of nonlinear dynamic equations are presented. Then, the multi objective dynamic optimization model is developed to minimize the value of vibration acceleration and the overall volume. The optimization of a practical example using mixed discrete combined programming is performed. The result shows that the proposed method of modeling and optimization design can effectively reduce the wind turbines gearbox vibration levels and weight.

Framework design of multimedia data parallel management in the informatization of rural areas

In order to realize the efficient transmission and analysis of multimedia data under TD-SCDMA network, a parallel management framework is proposed. This framework improves the general framework for data management by parallelizing the generation of standardized data and the analysis of original data. It not only reduces the data volume in transmission and analysis, but also fits for parallel optimization. Focusing on image analysis in the informatization of rural areas, the authors introduce the procedures to realize the parallel management framework. As can be seen from experiment results, the data volume of image data is reduced to 1/12 after parallel optimization, and the time cost of analysis is substantially reduced. Thus, it can effectively relax the requirement of the TD-WCDMA transmission bandwidth for multimedia application in the informatization of rural areas.     

Subjective and objective analysis on the sound quality of automotive wiper system

Car interior noise induced by windshield wiper system is tested for four different types of cars under high and low wiping speeds,and sound samples for subjective annoyance study are prepared. Grouped pair-wise comparison is adopted for the subjective evaluation test. The characteristic of subjective values and relation of four psychoacoustic parameters to the subjective annoyance are analyzed in two wiping speeds and various wiping patterns. The results indicate that the annoyance caused by wiper noise at high speed is higher than that at low speed,and downwards wiping noise is more annoying than upwards wiping noise. The work concluded that the subjective annoyance of noise from wiper system could be described by binaural loudness and fluctuation.
