Simulations of Protein Folding Process
A device for dispensing adhesive tape directly onto a surface includes a housing comprising a pair of spaced tear-drop shaped panels and a wall joining the peripheral edges thereof. A spool extending between the panels supports a roll of adhesive tape in rotatable fashion, with the free end thereof extending to a slot opening in the apex of the housing. A post extends between the panels medially of the roll and the slot opening. A spring member is secured to the post, one end thereof having a serrated cutting edge and anvil disposed in the slot opening, the other end impinging resiliently on the supply roll to act as a brake thereon.

Methods and Simulations for the Protein Folding
Corrosion of metals in contact with liquid systems is reduced by adding to the system a small amount of an amino carboxylic acid containing at least one hydrophobic group in combination with another nitrogen containing compound. The other compound is preferably an ether amine or a quaternary ammonium compound which also contain hydrophobic groups. The combination of substances is particularly useful for preventing corrosion in different areas of oil recovery and in petroleum industry.

Addressing mobility issues in mobile environment
In this paper we present an approach to overcome some of the mobility based challenges in the utilization of a mobile environment. As mobile devices utilize external resources in the mobile environment to overcome their limited capacity or performance, new challenges arise due to the mobility. In our approach the mobile device utilizing the resources moves in the mobile environment resulting connection loss. Unlike in task migration approaches our solution keeps the task execution in its original place and only the result is routed back to the mobile device. As we are using our previously implemented PeerHood middleware for the experiments the main challenge is in extending its operations to support routing in the mobile environment. This is done by extending the existing device discovery and by implementing routing service on top of PeerHood.

A low complexity method for real-time gaze tracking
The paper addresses a novel, fast and low complexity gaze tracking method, which remedies computation complexity and real-time processing problems of most existing gaze tracking methods. Face images are captured and pre-processed under infrared lamp-houses with dual thresholds. Pupil area is verified by the run-length in eight directions, and the gaze point is located by mapping the vectors of pupil and reflection point or using neural network. The experimental results show that the real-time processing of gaze tracking, with high resolution and high accuracy simultaneously, is achieved in this new system.

Numerical Simulation of Fluid Flow in Thin Slab Continuous Casting Mould
According to actual circumstance of Han Iron and Steel Company CSP, a three-dimensional mathematical model of fluid flow in the mould has been developed. The process of fluid flow is simulated in aid of fluid simulation software FLUENT, when we use two kinds of SEN separately in cast. The fluid flow in the mould is simulated at the difference of technical parameters (flow-guiding slot angle and submerge depth), when using two kind of SEN separately. And the optimum SEN configuration (flow-guiding slot angle) and submerge depth are fixed based on the numerical simulation.

Gait Planning Of Quadruped Robot Based On Third-Order Spline Interpolation
This paper presented a brief description for the gait planning of quadruped robot named Aibo ERS-7 which is a standard platform in the RoboCup 4-legged league. We approach a spline shaped locus to reduce the dimension of the parameter optimizing space and solve the problem of the significant bias between the planned locus and the real one. The result shows that the spline shaped locus is effective in finding the optimized locus shape in a short time. Finally, the robot achieves a gait faster than any previously known learned gait for Aibo

Single Trial Evoked Potentials Study during an Emotional Processing Based on Wavelet Transform
The present study aimed at examining the event-related potentials (ERPs) single-trial extraction during an emotional processing by wavelet transform and analyzing the brain responses to emotional stimuli. ERPs were recorded from 64 electrodes in 10 healthy university students while three types of emotional pictures (pleasant, neural, and unpleasant) from the international affective picture system were presented. All the subjects showed significantly greater P300 and slow waves amplitudes at antero-inferior, medial-inferior and posterior electrode sites for pleasant and unpleasant pictures than for neural pictures and unpleasant pictures elicited more positive P300 and slow wave effects than pleasant pictures. The results indicated the effectiveness of the wavelet transform-based approach in ERP single-trial extraction and further supported the view that emotional stimuli are processed more intensely.
