Abstract
In his book, Finite and Infinite Goods, The prominent Christian philosopher, Robert Adams, defends a weak version of divine command theory. According to this view, the nature of moral obligations is identical with being commanded by God. His argument for view has two stages. In the first stage he tries to show that the notion of moral obligation is essentially social in its nature. That is, moral obligations are constituted by social notions such as demands or commands of a third party such as a third person or the moral community. In the second stage he argues that this third party cannot be anything but God. In this paper I will try to criticize his argument in its first stage. I will show that his reasons and arguments for the claim that moral obligations have a social nature are inconclusive.

Abstract
Abstract- In this study, first the six axle depressed center wagon modeled with computer then its suspension optimized for transporting of high weight transformers in vertical direction on straight rails . For this purpose, We simulate dynamics of depressed center wagon in two ways,one by ADAMS / Rail software and by newton-euler analysis Dynamics method. Non-linear equations of motion and kinematical constraints have been solved in time domain. Then we define parameters that are influence on dynamics behavior of suspension element of the six axle depressed center wagon. In addition, optimization function defined base on Non Operating Shock Specification (NOSS) factor that is factor of Vulnerability when carry transformer. And in the end, suspension of this wagon optimized for Transporting of Transformers by perform many simulations on variation interval of choice parameters. Results show that stiffness of suspension element must change a little to dynamics behavior of depressed center wagon is improved.

Abstract
Anthropomorphic robotic hand has always been one of the interesting topics for researchers in recent decades due to its application range, including space exploration, medicine, military, etc. In this paper, a new plan is designed to drive exoskeleton fingers and by means of which the fingers can not only mimic human-like movements, but also be lightweight and portable. In this way, before implementation of the new plan, the anatomy of index finger and related kinematic were studied to give a hand to the extraction of angle relationships among distal, middle, and proximal phalanges. In upcoming step, theories, and mathematical relations about replacing sheaths and its influence on bending joints, based on the coupling mechanisms, were explained and applied clearly. Additionally, considering extracted relationships and equations in prior section, a new model of robotic finger with mentioned properties was simulated in MSC ADAMS software. In following step, after linking the software with Matlab, the results of the simulation and comparing them with human finger in the configuration and generation of humanoid movements were discussed. In the last step, according to simulation results, an example was constructed and presented, using a 3D printer in accordance with the proposed mechanism.

Abstract
The side branches in tomato plants have a great impact on tomato yield and fruit quality and the pruning work is now basically done manually, which has high labor intensity and high-risk factor. The elevated cultivation of tomatoes was taken as the objective of this research and 6 degrees of freedom P-R-R-R-R-R tomato side branch pruning robotic arm was proposed. The dynamic simulation of the robotic arm in the obstacle environment was completed by ADAMS. Simulation results showed the angular velocity and angular acceleration curves of each joint. A trajectory planning method combining Cartesian space and joint space was proposed to ensure that the robotic arm can avoid obstacles while effectively reducing the impact during operation.

Abstract
In this article, the kinematic and dynamic analysis of a multi-bar drum mechanism is discussed using Adams software. At first, the modeling of the mechanism is done in the catia engineering software, and then the model is entered in the Adams software. Then, by determining the appropriate joints, the initial speed is given to the mechanism and THE MOTION OF the mechanism is simulated. A kinematic analysis of the mechanism is performed and results of speed and acceleration of the joints are presented. The performed design and simulation show the effectiveness of the mechanism.
