CINR Performance of Downlink Mobile WiMAX IEEE 802.16e Deployed Using Coexistence Cellular Terrestrial and HAPS

Deploying WiMAX through High Altitude Platform Station (HAPS) system is a new means of wireless delivery method and thus attracting much the attention in a telecommunication society. However delivering WiMAX through the terrestrial network has already been started a few years ago. Therefore, we need to look at the scenario of coexistence system both of HAPS and terrestrial in delivering WiMAX services. This paper evaluates the performance of coexistence system between cellular HAPS and terrestrial for the downlink scenario when they are transmitting WiMAX mobile 802.16e services. Our evaluation is based on the performance simulation of coexistence model using two methods. First method is a footprint exchange between the two systems.The second method is a combination of footprint exchange and HAPS footprint enhancement. The proposed methodsare then evaluated by computer simulation in terms of carrier to interference plus noise ratio (CINR) performance. In general, both methods resulting performance enhancement in CINR quality compared with coexistence deployment with normal scenario of the cell configuration used by HAPS and terrestrial. The method of combining footprint exchange and HAPS footprint enhancement is able to improve CINR more than 10 dB compared with the normal footprint configuration for all users location inside the coverage

Analisa Teoritis Kebutuhan Daya Mesin Bubut Gear Head Turret

In the process of turning require power, in which the power obtained from electrical energy. The electrical energy is then converted into mechanical energy via an electric motor. How much power the electric motor is determined by several factors, among others: cutting speed, depth of cut, motion eating, cutting time and cutting tool material. In modern lathe used system is to make the gear head gear as the transmission power is driven by an electric motor. So that there is a relationship between the electric motor power on a lathe with head gear system to the cutting depth on a lathing process. The process of turning the workpiece AISI 1020 BHN 175, carbide tool with cutting tool angle of 300, cutting speeds of 300 fpm, motion eat 0.025 ipr, with variations in the depth of cut of 0.1 mm, 0,2mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm and 0.7 mm obtained will power the electric motors that vary according to the depth of cuts. The results of a theoretical analysis of the power requirements of gear head lathe turret with a variation of the cutting depth can be concluded that the theory obtained vary linearly extending line y = 2,6423x.
