Pemodelan dan Simulasi Robot Lengan 3 DOF Menggunakan V-REP
Movement of objects from one position to another position is usually by conventional method of human strength. Development of robotics technology makes movement of objects in the industry by arm robot system. By using arm robot system, the work more effective. The aim of this reaserch is to modeling 3 Degree of Freedom arm robot with kinematics method using V-REP software. Kinematics method is a subject that analyze robot movement without knowing the force that causes the movement. This research use the forward kinematics method so that arm robot can reach the goals. The input from this robot is an angle which is computed using the forward kinematics method. The output is an end-effector coordinate. Based on the result of the research, the 3 Degree of Freedom arm robot is capable to move the object from one position to another position and an error that occurs can achieve 4,99% for x coordinate, 5,57% for y coordinate, and 3,18% for z coordinate. Based on these results, the 3 Degree of Freedom arm robot with the forward kinematics method can be simulated in V-REP software effectively

Lithium ion transport in a model of amorphous polyethylene oxide
We have made a molecular dynamics study of transport of a single lithium ion in a previously reported model of amorphous polyethylene oxide. New ab initio calculations of the interaction of the lithium ion with 1,2-dimethoxyethane and with dimethyl ether are reported which are used to determine force fields for the simulation. We report preliminary calculations of solvation energies and hopping barriers and a calculation of the ionic conductivity which is independent of any assumptions about the mechanism of ion transport. We also report some details of a study of transport of the trapped lithium ion on intermediate time and length scales. © 1996 ESCOM Science Publishers B.V.link_to_subscribed_fulltex
Ab initio calculations for dissociative hydrogen adsorption on lithium oxide surfaces
Dissociative hydrogen chemisorption on the Li2O surfaces of the (100), (110) and (111) planes has been investigated with ab initio Hartree-Fock calculations. Calculations for unrelaxed crystal Li2O structures indicated that except for the (100) surface, the (110) and (111) surfaces are stable. Results on the heterolytic sites of n-layer (110) (where n⩾2) slabs and three-layer (111) slabs suggest that dissociative hydrogen chemisorption is endothermic. For a one-layer (110) slab at 100% surface coverage, the dissociative hydrogen chemisorption is exothermic, forming OH− and Li+H−Li+. This results also indicate that the low coordination environment in surface step structure, such as kinks and ledges, may play an important role in the hydrogen chemisorption process. On the homolytic sites of the (110) and (111) surfaces, there is no hydrogen chemisorption. © 1995, All rights reserved
The Effect of Supplier Trust, Supplier Innovation, and Buyer-Supplier Relationship in Enhancing the Supplier Performance on the Death Service Companies in Surabaya, Indonesia
Changes in customer needs from a service company results in changes requirement from the supplier to meet the company's demand. Excellent supplier performance is one of the mandatory requirements enabling the company to meet the customer demand. Better supplier performance can be improved when they have an excellent buyer-supplier relationship. The buyer-supplier relationship through better supplier trust from the buyer which means the company believes that the supplier can meet the needs of the company. Further, the supplier builds innovation providing better value to the company. This research examines the influence of supplier trust, supplier innovation, and buyer-supplier relationship to improve supplier performance at death service company in Surabaya. Data were collected by distributing questionnaires to 52 service suppliers in Surabaya. Data analysis using Partial Least Square (PLS) software. The findings show that all hypotheses are supported. There is a positive influence of supplier trust on supplier innovation and buyer-supplier relationship. Supplier-buyer relationship enhances the supplier innovation directly. Supplier innovation, buyer-supplier relationship, and supplier trust influence directly the supplier performance in death Services Company in Surabaya. This study provides new insight to the on-going research on the supply chain management. This work implies that manager can improve the supplier performance.
