Abstract: This paper focused the CIP (clean in place) rinse stage, typically applied to the food industry. The dynamic behavior of residuals removal kinetics was studied, to obtain mathematical models that describe adequately the system. The optimization of water, detergent, etc., is the next goal. The obtained results show that the temperature influence can be neglected in comparison with the rinse water flow rate considering the cleaning process. The systems dynamics are non linear and were adequately represented by 1^st order plus dead time transfer functions. The flow models obtained with this paper were validated versus experimental data and the results were close with respect to the last ones.

Abstract: Sensorineural hearing loss is caused by the damage of hair cells in the inner ear, the transmission of acoustical signal is disrupted without hair cells. In order to solve the problems exist in electrical cochlea,the idea of develop bionic microphone is proposed using the special property of piezoelectric material. Primary design of the size of bionic microphone is given with the reference of advanced manufacturing methods. According to the scope of human hearing threshold, Acoustical-structural coupling property of the bionic microphone is researched when the microphone is immersed in lymph. And the results shows that the displacement is going up at first and then down with the increasing of the frequency within 1000Hz, the displacement is 0.28mm when the frequency is 500Hz,and goes down to 0.205mm when frequency is 1000Hz. When frequency is varied from 1000Hz to 10000Hz, the displacement is changing apparently. The displacement has been changed from 0.208mm when the frequency is 1000Hz to 2.6um when the frequency is 10000Hz. Frequency selectivity is not clearly presented from the point of the location of maximum displacement,and this phenomenon may caused by the fasten mode of designed microphone and high Young modulus of silicon.

Abstract: Load bearing skate for the current weight is heavy and requires its own weight, but persist without improvement in the lack of capital and technology, but it is a reality. In this study, carried out phase optimal design to remove unwanted elements that do not have a stress to reduce the weight of skating that is being used for cargo transportation for, it reduces the weight of the objective function, we examined the safety associated with it.Using the FEM analysis Let's examine the effect on the failure strength by extreme temperatures that are used in the field of stress concentration due to discontinuity in the analysis at the time, structure - was carried out thermal analysis.Further, while ensuring safety through safety factor 2.1 and 20% weight reduction by the phase volume of for weight reduction.

Abstract: Greedy algorithms represented by orthogonal matching pursuit (OMP) and subspace pursuit (SP) algorithms are practically used in image processing based upon compressed sensing theory. However, there are two disadvantages: 1)Relatively poor signal reconstruction accuracy; 2) High computation complexity and measurements time. This paper proposes a frame of greedy algorithms obtaining a novel fusion of matching pursuit (FMP), combining the OMP and SP algorithms. FMP unites the two support sets from OMP and SP selecting the most appropriate atoms to achieve secondary screening of the original two support sets, finally realizing the accurate signal reconstruction. Using same test conditions, image reconstruction experiments and stability of Frame, the proposed FMP algorithm can effectively improve signal-to-noise ratio (SNR) with improved reconstruction error. Reconstruction effects using proposed FMP are better than separately using other two greedy algorithms for both high and low resolution images.

Abstract: In order to obtain accuracy interval velocity and improve the quality of imaging of velocity volume, so as to better describe the geological structure and reservoir of gas hydrate in specific area, a new interval velocity inversion combination method is proposed in this paper. By introducing wave ray tracing algorithm and velocity field structuring and smoothing algorithm, this new inversion solution can deduce more accuracy and reasonable interval velocity than other normal inversion methods. Empirical results shows that velocity profile has higher resolution and can finely reflect the occurrence status and spatial distribution of gas hydrate.

Abstract: In order to find a better inversion solution suitable for special gas hydrate exploration area with distinctive geological conditions, this paper proposed model based wave impedance inversion. This new solution can fully use seismic data and logging or pseudo-logging data to establishing an initial model. By continually modifies and updates the geological model through model selective preference iteration, the inversion can figure out a final model that possesses accordance with the actual seismic data. Model based wave impedance inversion can break the limit of traditional seismic resolution theory and can bring the interpreter high quality inversion result and high resolution profiles.

Abstract: Land surface temperature (LST) is important factor in global climate change studies, radiation budgets estimating, city heat and others. In this paper, land surface temperature of Guangzhou metropolis was retrieved from two MODIS imageries obtained at night and during the day respectively. Firstly, pixel values were calibrated to spectral radiances according to parameters from header files. Then, the brightness temperature was calculated using Planck function. Finally, The brightness temperature retrieval maps were projected and output. Comparing two brightness temperature retrieval maps, it is concluded that the brightness temperature retrieval are more accurate at night than during the day. Comparing the profile line of brightness temperature from north to south, the brightness temperature increases from north to south. Temperature different from north to south is larger at night than during the day. The average temperature nears 18°C at night and the average temperature nears 26°C during the day, which is consistent with the surface temperature observed by automatic weather stations.

Abstract: A measurement and analysis system is designed base on the requirement of digital upgrade to the KY231 Material strain tester. This system is made up of two parts :The analyze system based on the LABWINDOWS and the measurement system based on STM8S207. The physical quantities (such as stress, pressure, deformation, etc.) of the metal specimen are acquired, displayed and analyzed digitally in this system, meanwhile the experimental data and curves can be stored in the systerm and compared to the historical data saved in the previous files. Because the USB interface is too complex to the MCU systerm form the aspart of the programming and circuit design, the PL2303 is used to simulate USB interface as virtual RS232 for the communication between the measurement system and the analyze system.
