Gelling properties stability of the Maillard-type and dry-heating egg white proteins (MEW and DEW) were investigated. MEW were prepared by storing sugar-preserved egg white proteins and glucose at 60 °C and 79% relative humidity for 2 days, and DEW were prepared by storing at 80°C in dry state (7.5% moisture content) for 7 days. The results showed that both MEW and DEW have excellent gelling properties. After storage at room temperature for 180 days, gel hardness, spring and cohesiveness of MEW increased by 1.92%, 1.89% and 4.24% respectively, water holding capacity of MEW gel decreased by 1.42%, while storage time had a considerable effect on those of DEW gels. A tight and more uniform network with constant stability in the course of storage was observed in the gel of MEW (500×), while gaps in EWP gel network were larger and the gel texture became looser with storage time. The results demonstrated that gelling properties stability of MEW is better than DEW.

Micro-payments are very small sums of money, typically used to pay for content access or for small quantities of network resources. However, the existing micro-payments have the following drawbacks: firstly, generated e-coins only connecting with one particular merchant; secondly, only one unit value or one kind of currency is provided; and thirdly, needs multiple hash chain. In this paper, we constructed an efficient micro-payment protocol based single hash chain. The user only generates a hash chain to do business with multiple merchants. Using the hash value of monetary value generated by the broker, the user can spend different monetary value by a hash chain.

The stiffness of pristine glass fibre and glass fibre coated with starch sizing agent were studied on different storage conditions. The results indicate that the glass fibre coated with starch sizing agent is greatly influenced by the environment. It was confirmed that the starch sizing agent is the main factor affecting the stiffness of glass fibre. Using SEM, FTIR, XRD, DSC, three kinds of starch sizing agents under different storage conditions were studied. The results show that dried starch films produce holes that absorb water in humidity environment. Some bound water formed during the moisture absorbing process. The molecular structure, ordered degree and heat resistance of deteriorated starch is affected by the wet storage conditions.

In order to investigate the maximum stairs-climbing capability of the six-track robot with four swing arms and the centroid position control in the climbing process, firstly, the isolated steps and successive stairs in reality environments were simplified into a model that composed of horizontal planes and vertical planes; afterward, the robots centroid distribution was analyzed, the step-climbing methods and processes were given, and the relation equations of the step height, the arms swing angles and the main track evaluation angle were founded; Lastly, the conditions of the maximum step height and the conditions of climbing successive stairs using the slope-climbing method was deduced. Using the parameters of CUMT-III type coal mine exploring robot prototype, the relation curves of the step height and the robot elevation angle was drawn when the rear swing arms spread, and the 3D relation graphs of the robot elevation angle, rear arms swing angles and the step height were drawn, when the swing arms took some specific swing angles. The maximum theoretical step height of the prototype were obtained, which were compared with the test results in laboratory. This paper will provide theoretical basis for centroid position control in steps and stairs climbing process.

Due to the difficulty of expropriation, dump technology is experiencing the tendency of higher bench, heavier dumping intensity and larger dumping equipment. Therefore, accidents of dump bench instability or general shear failure on foundation soar rapidly. The capacity decreases because of reducing the heap height, and the high cost would be unacceptable if the soft layers of foundation were strengthened or cleared up. The practicality of passive control measures, such as rockfill dams and retaining walls locating at slope toe is analyzed; the validity of catch drains is evaluated, based on the interacting characteristics between the waste dump and the foundation. The design principles, permission of deformation and moderate failure, are submitted with considering consequence to surroundings. Active countermeasure mechanism is established according to spatial effect, reasonably using dumping-site space and adjusting time-space relation during dumping.

Part of the east wing belt roadway in -450 level east, NO.1 mining area, Dashu village coal mine, Jizhong Energy Fengfeng Group was under the 172102 working face’s stop mining coal pillar. The phenomenon of the stress concentration was obvious, the pressure of the roadway was large and the surrounding rock damaged severely. Concrete filled steel tube supports were used in stress concentration region. The supports type was φ194×8mm, and distance between supports was 800mm. They were of rapid construction speed, better supporting effect. The numerical simulation results also showed that the concrete filled steel tube supports can reduce deformation of the roadway surrounding rock in stress concentration region effectively.

Phosphate of chrome-alumina (PCA) matrix composites were successfully prepared via thermoforming by using chrome-aluminum phosphate as adhesive, ZnO as curing agent and single component or combination of Al2O3, SiO2, SiC and Si3N4as fillers. We have studied the effect of different fillers on the mechanical properties, dielectric properties and moisture absorption rate of composite materials. Results show that, for the PCA-III system, when curing temperature is 180°C, the dielectric properties of materials are the best and the moisture absorption rate is the minimum; When the amount of filler is 35%, the mechanical properties of PCA-III system are the best (i.e. the tensile strength is 94.4MPa and the flexural strength is 134.7MPa).

In order to determine the key parameters of blueberry picking machine, the three-dimensional solid modeling of Blueberry Picking System is researched based on the Pro/ Engineer of CAD software.

Discharge parameter on the reshaping accuracy and efficiency was studied in the reshaping processing. Therefore, a group of discharge parameters for emery wheel dressing were obtained.

This paper focuses on a heart sound acquisition and analysis system for in-home use of heart condition monitoring. The acquisition board is comprised of a transducer and the processing module, which is used to detect and send heart sound signal to PC via USB interface for heart sound analysis. The analysis software identifies normal and abnormal heart sounds, and provides an easy understanding graphical representation. Both normal and abnormal heart sounds are used to verify the validity of this system, and the result shows the system can discriminate normal and abnormal heart sounds. It is envisaged that the system can eventually be used for in-home use of heart condition monitoring that even inexperienced users are also able to monitor heart condition easily.

The paper presents the compatibility relation of displacement, strain energy expression, and the formulations of Finite Element Method in the transitional region for the improved damage model of 2-D delamination[1]. The postbuckling behaviors of composite laminated plate with a circular delamination are analyzed. Results show that the model mainly improves computational results of energy release rates in the delamination front. The model should only be used in a narrow region near the crack-tip and the normal Mindlin model in other regions. It leads to little increase in the amount of computation, but significant improvement in the results.
