Abstract: Intelligent assembly cell conception includes new solution kind of how to create structures of automated and flexible assembly system. Intelligent behavior of the system as the control system will repose on monitoring of important parameters of the system in the real time. The designed automation sensory equipment provides for automatic monitoring of all automated equipment motions in the first case and in the second important level is important to obtain the information about the status, presence and character of the assembled objects or assembly process. The application of the sensory equipment in the intelligent assembly process is designed on the ground of the sensory object properties of the pneumatic actuator model. In the paper is described the sensor equipment application for the assembly part sorting situated before the input of the object into the assembly process and for the check function of assembly product is designed the combination of sensory equipment.

Abstract: Several procedures have been proposed to overcome various challenges of product-content analysis after manufacturing and downstream automated recycling processes. These procedures have been restricted by factors such as the inability to determine exactly the physical state of the hidden parts of End-of-Life products. This inhibition among others has resulted into an explosion of solutions by researchers. This paper presents the initial investigations in the development of imaging software. The software supports a novel method of integrating scanned and digital imaging in material identification to overcome some of the existing shortcomings of automated recycling processes. The description of the software-algorithm structure and its centrality in post-manufacturing and automated recycling processes concludes this paper.

Abstract: Computers have made the greatest impact in the advancement and development of almost all aspect of human endeavour, particularly in the engineering field. In this research, effort is geared towards improving the universal design and final manufacturing of commercial cams in many automotive and other related companies around the world. A software package for the design and profile simulation of plate cams with a possible choice of two followers (Roller and Flat-Face) using eight standard cam motions for over one hundred and eighty-nine different follower profiles has been developed. The developed software provides the tools to analyze critical aspects of cam design before physical prototyping or production of such cams and followers, thereby increasing their reliability and performance. The developed software does not only remove the tedium associated with cam design process but also speeds it up dramatically thereby making the process of comparative design analysis and optimization easier and faster.

Abstract: In this paper, the authors analysed the impact of machine breakdowns in job shop scheduling problem with parallel machines. A mathematical model with the objective of minimizing the weighted value of makespan and early due date was established. An improved ant colony dynamic scheduling algorithm combined with elite strategy and max-min ant mechanism was designed. Simulation experiments were designed and numerical results verified the superiority of the proposed approach.

Abstract: This survey firstly reviews motion capture technology and the current challenge associated with the application in virtual human's control area. Secondly simplifies Jack's joint hierarchical model in order to drive Jack's virtual human to move by motion capture data. Thirdly uses Euler angle rotation equation to achieve pose mapping between BVH and Jack. Finally, results from experimentation show that when the motion capture data contained rich human motion details are retargeted to Jack by the paper's algorithms, the real-time interaction between virtual human and environment seems more real.

Abstract: This paper reports the design of an optimal controller to prevent suppressvertical vibration due to undesired out of plane excitations generated by environment or gripper during manipulation for a CMOS-MEMS Nano-Newton capacitive force sensor applied for biomedical applications. Undesired out of plane excitations generated by environment or gripper during manipulation is the most prevalent source of vertical vibration in this type of sensors. To suppress the vibrational movement a PZT 5A is used as actuation mechanism. Discrete element method DEM model and Modal analysis were used to find dominant natural frequencies and mode shape vectors. To eliminate out of plane excitation an optimal linear quadratic regulator is proposed using By State-Space formulation. Simulation results illustrate that by employing optimum LQR control approach the maximum disturbance input is suppressed less than 0.7 sec with acceptable range of control voltage amplitude.

Abstract: Artificial neural networks have become a powerful modeling tool. However, although they obtain an output with very good accuracy, they provide no information about the uncertainty of the network or its coverage intervals. This study describes the application of the Monte Carlo method to obtain the output uncertainty and coverage intervals of a particular type of artificial neural network: the multilayer perceptron.

We present in this paper an overview of potential applications of Augmented Reality that can provide positive results to the CIM approach. Also the paper comprises the results regarding how Augmented Reality is successfully tested and implemented on a FESTO assembly line.

Abstract: This paper is a pilot study using qualitative analysis to obtain concepts related to individual perceptions of Chief Executive Officers within various industries internationally. These concepts are related to emerging technologies such as mobile devices and their usefulness within a business and personal context. Technology has played a role in human affairs including business for millennia – starting with the lighting of the first fire, the carving of ideograms on the walls of caves and inventing the first round artifact that would eventually serve as a wheel. This research has empirically documented the ways and means that mobile technologies and “Smart-phones” impact an executive’s productivity and efficiency at work by conducting a series of opened ended interviews. Our findings further corroborate the presence, role and impact of what we call “happy accidents” in terms of strategic knowledge serendipity and arbitrage (SKARSE™) as factors shaping and even driving choices made by business leaders with strategic intent and implications.

Abstract: In time past, designs of shafts were conservative in approach as relatively low working stresses were employed to cover up for unknown “Factors of Ignorance”. [1]. And where high stresses are involved, greater shaft dimension is employed for such design. This approach necessarily made the production cost high as quite a lot of materials are involved in such production. The primary reason for such approach is to safeguard the shaft failure in most operations. Unfortunately, the mechanism of failure mode was not well understood and because most of the applications in which shafts are employed are of great importance, which in some cases affects life negatively (i.e. involving loss of lives) and distortion of operations. Despite all these developments, designers are still faced with the problems of working with large numbers of formulas, computations and iteration procedures involved in the design of shafts. These have made the design procedures of shafts both cumbersome and rigorous, hence time consuming. This problem becomes more pronounced if the designer is interested in seeing the effects of the variation of one or more design parameter, this means he has to start again from scratch. Fortunately, these problems can be overcome if the various advantages, utilities and flexibilities which modern high – speed micro – computers offer are put into good use in the design of shafts. This study was carried out to design shaft under various loading conditions using Computer Aided Design, and results gotten proved that it saves wastage of materials, and it safes time as well A software package (or program) was developed using the formulas initially derived and a numerical procedure for computing the deflection using the double integration methods. The Programming language used was Visual Studio C#. This objective was achieved in part as the program so developed satisfactorily handle design based on strength and safety of the shaft.
