This paper proposes a micro-simulation model for urban freight movement, in which the behavior of freight agents and their relationship in supply chains are incorporated. The proposed model is a modification of the traditional four-step approach in that it considers the behavior of each freight agent individually. This paper covers three of the four steps of the traditional approach, including ...

the light of the Genius Loci theory. The theory has been verified in many studies by the traditional-Islamic philosophers. Proving the closeness of these two viewpoints in extent and type of the environmental influences on disposition can open a venue for applying the theory of Genius Loci to establish a basis for environmental design in regions with Islamic and traditional cultures. This re...

Abstract. In order to improve the steady output of micrgripper, the giant magnetostrictive micrgripper with flexure hinge is taken as the research object . Its structure and working principle are presented .the static performance experiments are done and the better linear work domain is found. On the basis of that the dynamic model of the microgripper is established and the formula of the micro...

We report a theoretical investigation of effective four-photon absorption (4PA) process and propose a two-step 4PA model of three-photon- induced excited-state absorption (ESA). Based on three-level rate-equation theory, we find an analytical result for the effective 4PA coefficient that depends on the three-photon absorption (3PA) cross-section, excited-state photophysical properties, and lase...

Recent research work concerning cooperative and concurrent engineering, increasingly interest industrial firms. Companies can no longer ignore this approach due to industrial needs such as improvement of quality and reduction of cost and delay. The objective of this paper is to propose an approach allowing the different experts or firms, to cooperate via Internet. To facilitate the communicatio...

Computer-Aided Inspection Planning (CAIP) has been a research topic for the past 25 years. Most of the CAIP systems were developed for Coordinate Measuring Machines (CMMs). The authors reviewed these CAIP systems and categorized them into two groups: tolerance-driven and geometry-based CAIP systems. Compared with CMMs, On-Machine Inspection (OMI) systems provide direct inspection in manufacturi...
