Abstract :

The demand of high data rates is increasing day by day. The user needs to access all the multimedia applications on its mobile phone anytime, anywhere. For this purpose LTE was launched. As LTE provides high data rates, better efficiency to the network, but at the same time LTE-A is affected by interference in downlink, especially at the cell edge. The degradation of connectivity occurs due to inter-cell interference, which occurs when user is receiving the signals from two neighboring base station at same frequency, so in this case the mobile phone can maximize the received signal strength by adding up these two signals coming from two base stations, here problem arises for the user for the selection of base station, so coordination is applied between the cells to reduce the interference between the cells. This paper focuses on coordination between the base stations. DCS (dynamic cell selection selection) is used for coordination among the base stations, which will compare the CSI (channel state information) of base stations. The interference directly affects the parameters such as noise interference, receiving diversity and system receiving gain. In this thesis, SINR of the system is analyzed when coordination is applied between the cells. Initially the SINR is compared without coordination and then SINR is compared with coordination and then the results of both scenarios are compared.

Abstract :

The rate of heat transfer to water around a pipe can be greatly enhanced by the use of extended fins. The main objective in improving the performance of thermal system is to enhance heat transfer. To increase thermal performance of water heating boiler, it is necessary & effective to employ extended surface, referred to as fins, on the central pipe, to compensate for the low heat transfer coefficient. The prototype finned tube consists of equi spaced fins mounted on the outer surface of tube, in order to locally augment heat transfer between the fin base area & the surrounding fluid. Because heat conducted through fins is very efficient for metals, it results in high fin surface temperature and an increase of total active area.

Abstract :

The steady flow of the internal flow field in a sewage pump was numerically simulated and analyzed as a solid–liquid two-phase flow was transported. The simulation and analysis were based on the mixture multiphase model, the RNG k–ε turbulence model, the frozen rotor method, and the SIMPLE algorithm. The impact of the solid–liquid two-phase flow on the hydraulic performance of the sewage pump and the attrition rate of the vane was emphatically analyzed under different solid-phase concentrations. Results show that, as the concentration of the transported solid phase increased, the pump lift and efficiency decreased monotonously. The shaft power also showed a tendency to monotonically increase. The solid-phase concentration on the pressure surface of the vane continuously increased as well. Under a high transportation concentration, the secondary part of the suction surface experienced the most severe wear. The equilibrium point of equal pressure continuously moved toward the leading edge of the vane. At the same time, the isoconcentration points of the pressure surface and suction surface moved toward the vane inlet.

Abstract :

Time-delay vibration Control Technology is applied to the precision instrument workbench, whose influence is analyzed jointly by the control of fractional derivative and delayed feedback. Delay feedback control with fractional derivative is considered the workbench modeling. The stability switch theory is used to analyze the stability of the delayed dynamical systems, and find the system stable region. In the frequency domain, the objective optimization function is established based on the frequency domain. The delay feedback control parameters are optimized by the PSO (particle swarm optimization) and we can get the optimized control parameters. What’s more, the system vibration response simulation analysis is taken under time domain. Simulation results show that the fractional derivative and delay vibration control technology combined with the active suspension system can achieve good damping effect under harmonic excitation and random road excitation. Simulation results show that fractional derivative and delay vibration control technology combined with the workbench is less than the without fractional derivative and delay vibration control technology combined value is reduced by 99%, The value of the velocity and acceleration feedback is reduced by 99% and 68% under harmonic excitation. It shows that the fractional derivative and delay vibration control technology combined with the precision instrument workbench can effectively reduce vibration and provide a theoretical basis for active control technology.

Abstract :

With the rapid development of long distance pipeline in China, the pipeline has no choice but crosses some complex landforms such as Mountain Area. In the river (ditch), slope, mountain, alluvial plain ,Pipeline has a high probability of damage. It is an increasingly important problem to adopt reasonable hydraulic protection measures for long distance pipeline in Mountain Area. Based on a large amount of paper reading and practical experience, combined with complex topography of Mountain Area,the article discussed measures of hydraulic protection and summed up the measures of hydraulic protection in Mountain Area according to local conditions to stop soil erosion effectively and reduce operating costs.

Abstract :

A multilevel inverter is a power electronic device that is used for high voltage and high power applications, with the added advantages of low switching stress and lower total harmonic distortion (THD), hence reducing the size and bulk of the passive filters. This paper proposes a new topology of a cascaded multilevel inverter that utilizes less number of switches than the conventional topology. Therefore with less number of switches in the circuit, there will be a reduction in the gate driver circuits and also in effect fewer switches will be conducting for specific intervals of time. The circuitry consists of smaller multilevel inverter blocks connected in series to achieve its characteristic output waveform. A five level inverter will be simulated and its effect on the harmonic spectrum will be analyzed. The system will be modelled with the help of MATLAB/SIMULINK. In this paper a new topology of the cascaded multilevel inverter has been shown to produce an increased stepped output with less number of semiconductor switches. With fewer switches, controlling the overall circuit becomes less complex, the size and installation area reduces. Based on the simulation results there is a decrease in the overall THD.
