this paper focuses upon the development of an efficient method for conceptual design optimization of a satellite. there are many option for a satellite subsystems that could be choice, as acceptable solution to implement of a space system mission. every option should be assessment based on the different criteria such as cost, mass, reliability and technology contraint (complexity). in this rese...

differential steering of in-wheel electric vehicle provides the functions of both active steering and power assisted steering with the coupling control of force and displacement transfer characteristic of system. a collaborative optimization model of the differential power-assisted steering system of in-wheel electric vehicle is built, with steering economy as the main system optimization goal,...

In this research we develop a mathematical construct for estimating uncertainties within the bilevel optimization framework of collaborative optimization. The collaborative optimization strategy employs decomposition techniques that decouple analysis tools in order to facilitate disciplinary autonomy and parallel execution. To ensure consistency of the physical artifact being designed, interdis...

Collaborative Filtering is effective to provide customers with personalized recommendations by analyzing the purchase pattens. Matrix factorization, e.g. Singular Value Decomposition, is another successful technique in recommendation system. We implemented Singular Value Decomposition algorithm to achieve the least total squared errors. Based on the result, item-feature Collaborative Filtering ...

This research is collaborative investigation with the general-purpose motor manufacturer. To review construction method in production process, we applied the parameter design method of quality engineering and tried to approach the optimization of construction method. Conventionally, press-fitting method has been adopted in process of fitting rotor core and shaft which is main component of motor...

Inventory routing problems arise as simultaneous decisions in inventory and routing optimization. In the present study, vendor managed inventory is proposed as a collaborative model for reverse supply chains and the optimization problem is modeled in terms of an inventory routing problem. The studied reverse supply chains include several return generators and recovery centers and one collection...

computer-supported collaborative learning (cscl) is a new trend in educational sciences. this study investigates how knowledge sharing and transferring can be facilitated by using cscl in a problem-solving setting. intervention of research is education regarding sustainable water resources management (swrm) by computer-supported collaborative learning (cscl). the purpose of this research was to...

Since the eighties of the 20 century that the social and organizational sciences are interested in networks as organizational configuration and the identification of the dimensions that determine or influence the effectiveness of their performance, their adaptability and resilience. Communication and power are two of these core dimensions, because they strongly influence the degree of trust lat...
