RANCANG BANGUN APLIKASI PENJUALAN DAN JASA SERVICE PADA SHOWROOM EXPO YAMAHA MOTOR DI KOTA PERDAGANGAN KABUPATEN SIMALUNGUN

Motorbikes are motorized vehicles that have two wheels. in a straight line lined up so that when the conditions go at high speed it remains stable because of the gyroscopic force. Moving at high speeds continues to run stable and at low speeds stability always depends on the settings. In Indonesia motorbike users are very popular because they are cheap, easy to reach, save fuel and the maintenance costs are not large. One of the most famous motorbikes in Indonesia is Yamaha with its founder from Japan named Yama Tarakusu. Yamaha motorbike is a service for consumers in providing motorized vehicle maintenance because it is designed by reliable experts. Yamaha Motor Trade Expo Showroom Simalungun Regency dealers selling motorcycles, spare parts while providing service services for consumer motorcycle vehicles have not been maximized and have not been satisfactory because they are still done manually on sales, especially in selling spare parts because there is no fast and accurate information regarding stock or inventory. In terms of service services, there is also no application system running at the Yamaha Motor Trade Expo Showroom in Simalungun Regency. The design of sales and service applications aims to facilitate and accelerate the sales data processing and motorcycle service, so that the administration of sales and information is faster and more accurate. Departing from this, the author designed the application of sales and service services at the Yamaha Motor Trade Expo Showroom in Simalungun Regency in the hope that sales applications and service services can provide fast, precise and accurate information.Keywords : Sales, Motorcycle Services, Microsoft Visual Studio 2010, MySQL

Collision avoidance for multiple Lagrangian dynamical systems with gyroscopic forces

This article introduces a novel methodology for dealing with collision avoidance for groups of mobile robots. In particular, full dynamics are considered, since each robot is modeled as a Lagrangian dynamical system moving in a three-dimensional environment. Gyroscopic forces are utilized for defining the collision avoidance control strategy: This kind of forces leads to avoiding collisions, without interfering with the convergence properties of the multi-robot system’s desired control law. Collision avoidance introduces, in fact, a perturbation on the nominal behavior of the system: We define a method for choosing the direction of the gyroscopic force in an optimal manner, in such a way that perturbation is minimized. Collision avoidance and convergence properties are analytically demonstrated, and simulation results are provided for validation purpose.

Peculiarity of Solitary Deflection Waves Dynamics on the Domain Walls of Yttrium Orthoferrite

The solitary deflection waves accompany moving antiferromagnetic vortices in the domain wall of yttrium orthoferrite. These waves allow to investigate generation and nonlinear dynamics of these vortices on the moving domain wall with the help of two-and three-fold digital high speed photography. As the domain walls and the antiferromagnetic vortices dynamics is quasi-relativistic with the limiting velocity c=20 km/s, which is equal to the spin-wave velocity. The dynamics of solitary deflection waves can be explained assuming existence of the gyroscopic force. This work is devoted to experimental results on the dynamics of the solitary deflection waves on the domain wall of yttrium orthoferrite.

Dynamic and Analysis of a Marine Stabilization Table

The purpose of this research is to design and construct a marine stabilization table. This table is fixed on a ship and can be self-balanced when the ship is moving in the sea. The stabilization principle bases on gyroscopic force created by a flywheel. The study also uses ADAMS software to simulate and analyze the virtual model. The analysis result shows that with a flywheel of 33 kg and a flywheel spinning speed of 3000 rpm, the maximum tilt angle of tabletop is 6.160when an 5 kg object is placed on edge of the one-meter-diameter tabletop. A prototype of marine stabilization table is also manufactured in this research.
