Electromagnetic Disturbances

The paper deals with electromagnetic disturbances in the form of current higher harmonics, which are generated by LED lighting elements. It presents the problems related to the formation and impact of higher harmonics in the electrical systems of commercial facilities. The results of tests and analyses of current distortions for two different LED lamps are included, and these are in reference to the parameters set out in the normal applicable standards. A system was then proposed to improve the quality of energy in the mains of commercial facilities in the form of a two-stage power supply. Tests of the systems with the aforementioned LED lamps were conducted and commented upon after introduction of the two-stage power supply. The final part of the paper contains a summary of the obtained test results.

In order to enhance the quality of iron concentrate from magnetic separation, reverse-flotation technology is often applied in iron ore dressing plant. However, this technology has disadvantages in operating cost, energy consumption and environmental protection (Zhao Chunfu, Wu Jianghua &Wang Hui ,2005). Developing innovative equipment to process magnetite ore more-effectively is a way to get rid of these disadvantages of reverse flotation and improve the quality of iron concentrate. This paper describes the development of Complex Flashing-Field Magnetic Cleaner, a new kind of equipment based on the principle of combination of separation in magnetic field and separation in gravity field (Hao Shuhua & Jiang Wenli,2002). This innovative equipment possesses a tailor-made magnetic system and has the characteristics of a magnetic field which can strengthen the formation of magnetic agglomerations and the dispersion of gangue minerals to improve the quality of separation. The automatic control system developed specifically for this equipment can further increase the accuracy of separation and stabilize the process. Test results showed that this equipment is reliable in operation, economically beneficial and it has large potential of application.

A frame work for analysing the capabilities and area of improvements for working of an embedded processor is constructed, and also a methodology for comparative study of simulation of processor on load and hardware results are explained in this paper. The processor can be modelled as a standalone processor or as a group of processors working together to take parallel program execution mode. The proposed frame work and simulation method uses the processor representation of current embedded processor model which is relevant in product design and devices modelling. This system utilizes the ARM processor model which consists of programs used for computing and standardizing the operational quality of a processor for any particular domain of applications. This paper presents steps for creating experimental framework which uses a simulation system running on a Linux based operating system along with kernel for running test applications on the target which is run in simulation mode. To evaluate the simulation with respect to the real hardware, this paper has made an observation of cache related performance of a typical embedded processor. The processor which is taken for the study is ARM926EJ-S processor. The future architectural components will be designed and simulated in the framework as continuation of this experiment. Their ARM9 technology equivalent design parameters for configurable modules of CPU in 1.8 micro-meter and experimental nano-meter level implementation would be calculated with architecture component design tools.

Simulation Results

In this paper, the characteristics of AC/DC converter under single-phase voltage sags and three-phase voltage sags are simulated with Matlab emulator. The simulation results show that effects on rectifier equipment under three-phase voltage sags are more serious than those under single-phase voltage sags. The flat wave capacitance plays an important role in voltage sensitivity of sensitive loads. In practice, the capacitance of flat wave capacitor is chosen according to the power supply and load requirements so as to realize the best balance of performance and price.

Good Agreement

The quality of blended yarn depends on the uniformity of the blending of the multi-component fibers in the yarn, and sliver blending is a process necessary for mixing fibers. The movement of fibers directly affects the distribution and mixing of fibers in the sliver. In this paper, the sliver blending process was simulated, and a method for the evaluation of sliver blending irregularity was proposed. The effects of passages of drawing and blending ratio on the sliver mixing uniformity were studied and verified both by experiment and simulation. The results show that the blending irregularity decreases gradually and tends to be stable with the increase of the passages of blending drawing. The more similar the blending ratio of the two components with approximately equal linear densities, the easier it is for the component fibers to mix evenly in the sliver. The simulation results are in good agreement with the measured values and previous research results. In addition, the blending irregularity of fiber components in the blended sliver can be predicted by the simulation method.
