Existing spatiotemporal database supports spatiotemporal aggregation query over massive moving objects datasets. Due to the large amounts of data and single-thread processing method, the query speed cannot meet the application requirements. On the other hand, the query efficiency is more sensitive to spatial variation then temporal variation. In this paper, we proposed a spatiotemporal aggregation query method using multi-thread parallel technique based on regional divison and implemented it on the server. Concretely, we divided the spatiotemporal domain into several spatiotemporal cubes, computed spatiotemporal aggregation on all cubes using the technique of multi-thread parallel processing, and then integrated the query results. By testing and analyzing on the real datasets, this method has improved the query speed significantly.

Auditory Rate

Although the visual modality often dominates the auditory one, one exception occurs in the presence of tempo discrepancies between the two perceptual systems: variations in auditory rate typically have a greater influence on perceived visual rate than vice versa. This phenomenon, termed “auditory driving,” is investigated here through certain techniques used in cinematic art. Experiments 1 and 2 relied on montages (slideshows) of still photos accompanied by musical selections in which the perceived rate of one modality was assessed through a recognition task while the rate of the other modality was systematically varied. A similar methodological strategy was used in Experiments 3 and 4 in which film excerpts of various moving objects were accompanied by the sounds they typically produce. In both cases, auditory dominance was observed, which has implications at both a theoretical and applied level.

Application Requirements

This article presents a review on two conveyors at the Ford Motor Co.’s Wayne, MI, assembly plant that use the same technology to meet two very different requirements. One system handles fully dressed, pallet-mounted engines in packages weighing up to 1600 pounds, while the other deals with pallet-mounted instrument panels having a total package weight of 80 pounds. The conveyors, supplied by Bleichert Inc. of Sterling Heights, Mich., use a roller drive mechanism that allows them to adapt to the different application requirements. Ford accomplishes the engine/chassis marriage by lifting completely dressed engines into the vehicle from below. The pallet-mounted engines are transported on a cart, called a moon buggy by Wayne plant personnel. The drive motor can be positioned anywhere along the length of the conveyor. It uses a gear reducer and timing belt to transmit power to the driveshaft. Each of the one-meter-long driveshaft sections is linked to the next one by a coupling to complete the modular drive system.

Linear Approximation Method

In this paper, determinate beam and indeterminate beam with multiple span are optimized by using genetic algorithm, the mathematic model of optimize beam is built and the processing method of constraint conditions is given. The examples show that the algorithm could be used for optimizing determinate structure, and also optimizing indeterminate structure. Compared to the linear approximation method, genetic algorithm has advantages of being simple, easy, fast convergence and has no use for changing the objective function and constraint conditions to linearity or other processing. Its results agree with linear approximation method’s. It is the other method that can be adopt in engineering field.

ABSTRACTFiduciary security is legal security over on moving objects both tangible and intangible, and building or a house on the land belong to someone else, either registered or not, which cannot be burdened with mortgage rights that keep in control of the fiduciary as collateral of debt repayment. If debtor as Fiduciary giver to be insolvent, so the creditor is entitled to have the fiduciary mentioned. For repayment of the debtor and the creditor in this case is called the right separatists.  There are many direct execution in banking practice about the object credit that are not perfect bound of guarantees or not through the insurance agency. Execution is doing by creditors, which debtor accompanied or not, or the object credit guarantees owner. Execution is done by regular sales or through creditor takeover.  Protection of creditors interest doing by giving legal aspects of registration precedes rights while providing executorial title for the fiduciary receivers benefit, on the other hand, the registration arrangements for certain objects that are not listed cause haziness opportunities of law implementation if it isnot done by carefully and clearly. To protect creditors interests, at the time of the debtor defaults, so that creditors as apreferential rights receiver in debt collection and as legal evidence, so warehouse receipts guarantee that the debtor should be given the imposition of bail.Key: Execution, Fiduciary, Creditors, Debtors

Imaging Sonar

Techniques for analyzing and avoiding hazardous objects and situations on the seabed are being developed to ensure the safety of ships and submersibles from various hazards. Improvements in accuracy and real-time response are critical for underwater object recognition, which rely on underwater sonar detection to remove noises and analyze the data. Therefore, parallel processing is being introduced for real-time processing of two-dimensional (2D) underwater sonar detector images for seabed monitoring. However, this requires optimized parallel processing between the modules for image processing and the data processing of a vast amount of data. This study proposes an effective parallel processing method, called Task Partitioning, based on central and graphical processing units for monitoring and identifying underwater objects in real time based on 2D-imaging sonar. The practicality of the proposed method is evaluated experimentally by comparing it to the sequential processing method. The experimental results show that the Task Partitioning method significantly improves the processing time for sonar images because it reduces the average execution time to 1% and 5% of the sequential processing method and general parallelization, respectively.

It is known that the flexibility and programmable abilities have made the FPGA widely used as controllers to the electrical machines and systems. Above all, the high density of recent developed chip results in many of the CPU cores and complicated hardware can be programmed into the chip to be as controller. Thus, this topic is based on the currently available technologies of FPGA-based system design to the parallel processing. Software and hardware co-design are shown to reach the performance, and the system’s software stream data are processed with the hardware parallel technique. This analysis enables FPGA-based control system on the parallel computing platform to achieve the simultaneous operation for 3-axis motor motion and drive system control. In that way, we chose the high density FPGA, Altera Cyclone II EP2C8Q208C8N, as the chip to develop the hardware of microprocessor, motor drive and motion controller. The developed system was practically applied to a 3-axis motion platform driven by stepping motors to evaluate the system performance.

SUMMARYWhen applied to rapidly moving objects with complex trajectories, the information-rate limitation imposed by video-camera frame rates impairs the effectiveness of structured-light techniques in real-time robot servoing. To improve the performance of such systems, the use of fast infra-red proximity detectors to augment visual guidance in the final phase of target acquisition was explored. It was found that this approach was limited by the necessity of employing a different range/intensity calibration curve for the proximity detectors for every object and for every angle of approach to complex objects. Consideration of the physics of the detector process suggested that a single log-linear parametric family could describe all such calibration curves, and this was confirmed by experiment. From this result, a technique was devised for cooperative interaction between modalities, in which the vision sense provided on-the-fly determination of calibration parameters for the proximity detectors, for every approach to a target, before passing control of the system to the other modality. This technique provided a three hundred percent increase in useful manipulator velocity, and improved performance during the transition of control from one modality to the other.
