The Role of Motion Planning in Robotics MASEHIAN Ellips Faculty of Engineering, Tarbiat Modares University, Tehran, 14115-143, Iran masehian@modares.ac.ir Keywords: Robot motion planning, Path planning, Robotic tasks, Configuration space.
These types of robots are widely used in industry for welding, painting, material handling, etc., and since they change their shape through moving links and joints, they are classified as conformable robots.
First, the basic and key concepts in motion planning such as workspace, configuration space, complexity of motion planning, etc. are discussed, and then the variations of the basic motion planning problem are presented through a new taxonomy, which is called WRIT and covers various elements of the Workspace, Robot, Information, and Task components of a motion planning problem.

Studies on Foam Flow in the Porous Media in the Last Decade: A Review Mingming Lv a, Shuzhong Wang b, Zefeng Jing c, Ming Luo d School of Energy and Power Engineering, Xi'an Jiaotong University, Xi'an, China am.m.lv@stu.xjtu.edu.cn, bszwang@mail.xjtu.edu.cn, cjingzefeng@stu.xjtu.edu.cn, dlm4875102@126.com Keywords: Mobility, Trapped gas, Foam texture, Population-balance model Abstract.
For each EOR method, different material is injected to extract oil out of the reservoir.
The solubility of CO2 would be the key factor for the differences between CO2 foam and N2 foam.
The only difference among the experiment phenomena observed was that the red dissolved material did not flow out of the Boise sandstone core but did in other two cores.

Introduction Current manufacturing environment can be characterized in terms of many factors but the key one for companies confronting the challenge of remaining competitive in an era of globalization is undoubtedly the capability of fast and accurate decision making, especially so in the mass customized production/services domain.

Modeling and Optimization a Production/Maintenance Integrated Planning Ghita Ettaye1, a *, Abdellah El Barkany1,b and Ahmed El Khalfi1,c 1 Mechanical Engineering Laboratory, Faculty of Science and Techniques, Sidi Mohamed Ben Abdellah University, Fez, Morocco.
Production Plan In the literature, as a first solution of production planning we found the MRP I (Material Requirement Planning) that started between 60 and 70 years ago [3] but this model did not consider the constraint of resources capacity.
Indeed, communication and collaboration between the maintenance actions and the production operations are the main keys to success organizing and planning a production system.

Influence of Laser Remelting on the Corrosion Resistance of Fe-based Amorphous Composite Coatings Chao Liu1,a, Yongtian Wang2,b*, Lin Hu2,c, Runsen Jiang2,d, Jingkang Duan2,e, Zigong Xue2,f and Gang Xu1,g 1Beijing Key Laboratory of Emission Surveillance and Control for Thermal Power Generation, North China Electric Power University, Beijing, 102206, China 2Key Laboratory of Condition Monitoring and Control for Power Plant Equipment of Ministry of Education, North China Electric Power University, Beijing, 102206, China.
Among these, the Fe-based amorphous coating is known to be an excellent candidate for protecting steel surface because of their high corrosion resistance, high mechanical strength and relatively low material costs [10].
Relatively simple thermal spraying methods have been widely used in the surface engineering to offer corrosion and wear protection.
As a result, this amorphous composite coating with a wonderful corrosion and wear resistance can realize a wide application in modern engineering.

In many engineering and industrial processes, the entropy production destroys the available energy in the system.
The second law of thermodynamics is more reliable than the first law of thermodynamics because of the limitation of the efficiency of the first law in heat transfer engineering systems [14].
Entropy generation minimization is applied in various thermal engineering systems such as air separators, reactors, chillers, fuel cells, thermal solar, chemical and electrochemical.
The key findings of the article are concluded at the end of the manuscript.
The Prandtl number is chosen the values ranging from which are the most encountered fluids used in plasma physics, engineering and industries.

Robustness based structural design: an integrated approach for multi-hazard risk mitigation Dubina Dan1,a and Dinu Florea2, b 1The ”Politehnica” University of Timisoara, Faculty of Civil Engineering, Timisoara, Romania 2The ”Politehnica” University of Timisoara, Faculty of Civil Engineering, Timisoara, Romania adan.dubina@ct.upt.ro, bflorea.dinu@ct.upt.ro Keywords: extreme loading, risk, robustness, column loss, ductility, steel structures.
However, this should not be assumed apriori, as there are also differences between these hazards and their effects on structures, for instance, the rotation demand of connections associated with the loss of key structural elements.
However, for progressive collapse analysis of the main structural system, the behavior of the material can be considered rate independent.
