Abstract: Employment evaluation for university student based on analytic hierarchy process is presented in the paper.The influencing factors of employment evaluation for university student are analyzed, and weights of employment evaluation indexes for university student is obtained. Employment evaluation of a certain university is employed to study the evaluation effectiveness of analytic hierarchy process.Finally,the evaluation values of the employment evaluation for university student of the university are obtained,which indicate that the evaluation level of the employment evaluation for university student of the university is ‘good’.The evaluation result is consistent with the actual situation,which shows that the employment evaluation for university student based on analytic hierarchy process is feasible.

Abstract: In this paper, a new method using a Secure Digital Card in debugging an embedded system based on Android and its implementation are introduced. In debugging an embedded system, downloading image files to a RAM on a printed circuit board generally uses a net interface module and a server based on Trivial File Transfer Protocol (TFTP). Here a new method using an SD card is introduced. Compared with downloading by a TFTP server, the method is simple and inexpensive. In the paper, an SD card and its controller are introduced first. Then the designed circuit is presented. Third, two operation modes of the SD card, card identification and data transferring are analyzed in detail. Fourth, the structure of the FAT32 file system and the process for downloading image files into a RAM on board are shown.

Abstract: Application of electron acceptors to mitigate CH4 emissions form paddy fields deserves special attention, especially for ferric iron oxides as its dominant role over all other redox species. Silicate iron slag is a by-product of the steel industry.We added it in the experiemental sites of paddy fields in the Fuzhou Plain, a subtropical coastal plain region.. After the addition of the silicate iron slag, the soil showed a lower soil Eh and higher pH, especially at the early period of cultivation(about one week). CH4 emission during the cultivation period significantly decreased, about 26.4%, 43.3% and 48.9% for 2 Mg ha-1, 4 Mg ha-1and 8 Mg ha-1 silicate iron slag treaments, respectively. In conclusion, silicate iron slag could be considered as an effective method to mitigate CH4 emissions from subtropical paddy fields.

Abstract: The purified TGase produced by Streptomyces mobaraensis DSM 40587 from high salt medium was applied to whole and skim milk yogurt. During yogurt fermentation, no negative effect of TGase on fermentation time was found. Protein cross-linking by TGase was enhanced at varying concentrations from 0 to 5 U/g protein, resulting in a increase of apparent viscosity and decrease of syneresis. Furthermore, texture parameters were improved. However, extensive cross-linking resulted in too big size of the aggregates. The formation of these polymers resulted in a coarse texture of yogurt. Fat had no impact on the apparent viscosity and texture parameters, but significant changes in cross-linking of protein, syneresis and the sizes of the aggregates. From the range of TGase concentrations examined for properties of yogurt, the optimal level of TGase for skim milk yogurt was 1 U/g protein; however, for whole milk yogurt was 3 U/g protein.

Abstract: The myofibrillar fragmentation degree (MFI), value of pH and the degradation degree of sea bass with high pressure treatment were studied. The results showed that the degradation degree of protein, MFI and pH of sea bass increased as the pressure increasing, indicating that ultra high pressure treatment could change the tenderness of sea bass muscle, which has a certain practical significance in the food industry.

Abstract: The present article deals with the issue of evaluation of state of urban power supply systems (hereinafter PSS). Such systems are characterized by large size and low reliability of the available data. The suggested evaluation model (EM) is based on elements of the fuzzy logic theory and on the informational graph structure of the power network. EM allows for evaluation of the PSS objects irrespective of their size. PSS object here stands for any part of the PSS, from power switch to complex PSS with substations and transmission lines of various voltage. Graph-based structure of the network model (NM) provides for connection between the objects and allows to select parts in necessary and sufficient detail. Evaluation is made by quantitative indicators that reflect performance of the objects in various spheres (technical, exploitation, ecological etc) with transition to qualitative states: normal, pre-emergency and emergency states.

Abstract: Ti-6Al-4V green body was processed by gelcasting. Effects of the powder morphology, dispersant and pH on the solids loading were investigated. The morphological properties were investigated by SEM. The results show that the powder morphology is the overriding factor in slurry processing. Slection of dispersant and pH are another two critical factors affecting the solids loading by a percentage of 2 to 4. With optimum conditions: spherical powders, 1.5 wt.% ammonium citrate as the dispersant and pH=11, the green body with high solids loading of 59.4% was prepared.

Abstract: The traditional methods used to select refrigerating compressors need a large calculation, take much time and contain some estimating errors. To establish the energy consumption model of compressors can imitate the performance curves of compressor. It makes selecting compressor without chart and only concerned with condensation temperature and evaporation temperature, which greatly improves the speed and quality of selecting compressor.

Abstract: Mobile target tracking is a key application of wireless sensor network-based surveillance systems. Sensor deployment is an important factor in tracking performance and remains a challenging problem. In this paper, we address the problem of optimal sensor deployment for mobile target tracking. We analyze the tracking performance of three patterns. Simulation results demonstrate that the irregular pattern outperforms the other two patterns.

Abstract: Fourier transform infrared spectroscopy (FTIR) and attenuated total reflection (ATR) combined with partial least-squares (PLS) and Savitzky-Golay (SG) smoothing were successfully applied for rapid no-reagent determination of hemoglobin (HGB) in human whole blood. The optimal SG smoothing parameters OD, DP, NSP and PLS factor were 1, 2, 49 and 14, respectively. The modeling effect M-SEPAve, M-RP,Ave, M-SEPStd, and M-RP,Std were 6.73g/L, 0.850, 0.306g/L, and 0.015, respectively. The validation effect V-SEP and V-RP were 6.83g/L and 0.864, respectively. The method provided a reliable model with stability for clinic application of FTIR/ATR.
