An application of artificial intelligence to composite materials design is presented. An expert system for materials optimization is illustrated. this system has to process different types of knowledge: mathematical setups and models, finite element analysis (FEM), and heuristic and fuzzy knowledge. For proper operation and useful results the system contains links to databases and external systems like: materials databases, corrosion databases, and databases/systems with knowledge properties, compatibility, corrosion behavior, etc. A first prototype of the system was implemented using the expert system shell KEE. the system is under test and first results show that it can be used as an adequate tool for composite materials design and optimization.

Flying Ad-hoc network (FANETs), a new kind of mobile AD hoc network, uses the aircraft as the air wireless communication node to construct a network and achieve effective communication at the network layer as a result of the ongoing expansion of communication networks into many industries. However, the high dynamics, limited node energy, and low network density of the FANETs present significant challenges to the FANETs routing protocol, which requires urgent attention in terms of its design. In order to address the issues associated withthe routing metric of the FANETs routing protocol, such as the underutilization of link information and the inadequate consideration of the motion of UAVs, which result in high network packet loss rates, unstable routing, and long route reconvergence times, this paper proposes the Predictable Track-based Routing Protocol (PTP). PTP divides the routing protocol into three stages: route establishment, data transmission, and route maintenance. PTP creatively suggests Node Stability Factors (NSF) for UAV in the route establishment stage and develops a Q-learning algorithm to maintain it in accordance withthe status of the nodes and nearby nodes. NSF combined the link quality calculated by HELLO messages to generate a link quality based on Q-learning(LQQ) metric. After that, the optimal path from the source node to the destination node is calculated based on this metric. In the data transfer phase, data is transmitted through the routes calculated in the route establishment phase. Create a new HELLO message during the routing maintenance phase to learn the location of the neighbor node and the two-hop neighbor node, predict the node's future location using the Kalman filter algorithm based on the node's past location, and react quickly when the link is about to change. Compared to conventional approaches, experiments demonstrate that PTP may successfully raise the successful data delivery rate by 10% to 30%, increase the average route s

Background modeling is a key step of background subtraction methods used in the context of static camera. the goal is to obtain a clean background and then detect moving objects by comparing it withthe current frame. this paper describes a novel fuzzy approach for moving object detection which is capable of processing images extremely rapidly and achieving high detection rates. this work integrates the Local Binary Pattern texture feature and HSI color feature by a novel fuzzy way using the Choquet integral, which extends the moving object detection work for light illumination changing and shadowing. the results of several dataset videos show the robustness and effectiveness of the proposed method.

In a previous study, we analyzed data from afield study to determine the usability problems in a groupware system. that 75% of the system use was asynchronous surprised us. Consequently, we suspected that the user-centered method that had been employed in that evaluation, might have been insufficient to detect problems related to such henry asynchronous use. Re-analysis of the data using an artifact-centered approach revealed additional support for our initial findings and some new usability, issues. In combination, we believe that user-centered and artifact-centered methods can yield superior usability analyses for systems that support both synchronous and asynchronous collaboration, and provide application developers with more appropriate priorities for addressing usability problems and system design.

In the process of product design, structure, materials and process is interaction. Only knowing them as a system can design a good product. the designer make litter of structure, materials, process lead to a conflict between rational structure and emotional appearance, and the difference of concept design and the production program. the difference is sometimes a lot, and even unpredictable. Under the theory of the concurrent engineering and the deficiencies of designer,an intelligent assistant system of product form realization is established. the use proved it can reduce the difference, and conducive to the unification of structure rational and appearance Emotional.
