Nowadays, the importance of the vehicles and its dramatic effects on human life is no secret. The use of trailers with multiple axels for transporting bulky and heavy equipment is essential. Increase in trailers axles which results increment of wheels, needs considerations in order to increase in transporting speed, maneuverability, safety, better control and path following accurately.  Therefo...

Path planning algorithm is a key issue among robot control areas. In practical engineering applications, traditional methods have some limitations to a certain degrees in key aspects of cost, efficiency, security, flexibility, portability, etc. Through the analysis and comparison of A-star algorithm and Dijkstra algorithm, path planning problem supporting multiple cars run parallely (PPSMC for ...

In this paper, we focus on the problem of secure multicast in dynamic groups. In this problem, a group of users communicate using a shared group key. Due to the dynamic nature of these groups, to preserve secrecy, it is necessary to change the group key whenever the group membership changes. While the group key is being changed, the group communication needs to be interrupted until the rekeying...

A new dynamic friction model for modeling of elliptical vibration assisted turning (EVAT) was developed in this research. The periodic change of the friction force direction is known to be one of the most important causes of this phenomenon. In modeling of machining processes (including the EVAT process), static Coulomb friction model was employed by most of the researchers. Because of the peri...

In order to meet the performance requirements of global optimality and path smoothness in robot planning, a new fusion algorithm jump-A* dynamic window approach is proposed. First, A* optimized by using jump point search method distance evaluation function defined Manhattan Euclidean obtain information. Then take as core integrating information safely plan op...

A Mobile Ad hoc Network (MANET) is a selfconfigured, infrastructure less network. In MANETs wireless mobile nodes form a dynamic temporary network Due to mobility of nodes routing is a very critical issue in MANETs. Finding and selecting an optimal and reliable path that can exist as long as possible is a complex task. In the process of path selection and path failure, most of the routing proto...

Path planning is the key task in the field of Robotics. The modelling environment and algorithm to find shortest, collision free path are the basic issues in the path planning problem of the robot motion planning. This paper presents a literature review of different path planning techniques in static as well as dynamic environment. Planning a path in static environment is easy as compared to dy...

The rapid development of communication systems in the last few decades has increased the deployment of multimedia and real-time applications within it. These applications require the support of Quality of Service routing algorithms that support multiple constraints to provide a service the meets the user expectations. Applying QoS on mobile ad-hoc networks (MANET) raises the challenge because o...
