The recorded sound signals, with some signal processing applied, can be used to obtain the location of the nearby vehicles and also be sent to the driver to increase his/her awareness of the situation even if the physical sound has been blocked by the door or window of the vehicle. In this paper, we propose such an acoustic IOV using an integrated system of microphone arrays and digital signal processors (DSPs).

Authors: Hong Ying
Published: June 2014

To efficiently retrieve information from the vast source of the internet, search engines are required. There are some search engines that can help people to search for needed information, but they are difficult to ensure precision rate and personalization of information. To solve these problems, this paper proposed a personalized information retrieval system based on meta-search engine. This paper used multi-agent technology to construct the personalized information retrieval system, adopted user knowledge database to create and update user model and improved vector space model algorithm combining with user knowledge database which used in results ranking. Analysis and experiment show that personalized information retrieval system implemented in this paper can improve the precision ratio and can meet the needs of the user's personality requirements.

Published: June 2014

This paper presents a research that is developed inside “Products and Systems Design and Development” research group of Pontifical Catholic University of Paraná (PUC-PR). This research shows a study that are made to know the viability of develop an agents expert system with ontologies, to support dental prosthesis design decisions in dental prosthesis processes. Will be shown an overview of agent systems, approaching a framework used to provide agents software environment, the JADE. The planned expert system aims to analyses DICOM files with software agents and ontologies, specifically, when professionals need to choose a dental prosthesis by it characteristics. The methods used to guide this research were, the bibliographical survey to list de concepts, and, state of art for the expert system layout project and ontologies map and tests procedures. As a result, this paper shows that using agents and ontologies in expert systems development, allows better software scalability and modularization for complex and specialized software solutions.

Aiming at general constraints in vehicle routing problem in workshop, this paper improve and simplify some relative constraints to make it more in line with real conditions in workshop. Different situations are discussed and experimentally computed respectively. The results show that tabu search is effective to get satisfactory algorithmic solutions, and this problem can be expanded to meet more additional constraints.
A Brief Review of Trust Evaluation in Networked Manufacturing System
Authors: Liu Zheng Hong , Yan Kai
Published: June 2014

As an integrated manufacturing model, networked manufacturing system can facilitate collaboration among enterprises and enhance competiveness of enterprises. However, the problem of trust is a bottleneck which limits the development of networked manufacturing system. In order to ensure the transaction in networked manufacturing system work well, the trust-evaluation between transaction entities (i.e., resource service providers and demanders) appears crucial. By reviewing the researches of trust-evaluation from related scholars, the paper makes a conclusion about them and points out future work of trust-evaluation.
A Method for Multimedia Resources Management and Sharing in Cloud Manufacturing System
Authors: Liu Zheng Hong
Published: June 2014

In the entire life-cycle of manufacturing of a new product, a great number of multimedia resources are generated, which is belong to manufacturing resources too. How to manage and fully sharing these multimedia resources is a key research part for cloud manufacturing (CMfg), which is aim at realize the full sharing and on-demand use of various manufacturing resources. In this paper, after introduce the concept of cloud computing and cloud manufacturing, a cloud based multimedia resources management and sharing method is proposed, as well as is architecture.

Published: June 2014

Adopts the method of adding demulsifiers into the oily wastewater to increase the droplets size to further improve the efficiency of oil-water separation, and puts forward the corresponding optimized indicators and methods of demulsifiers. The optimized selection of the demulsifiers and its additive dosage was carried out by indoor experiments based on the optimized indicators. Using artificial produced water to test the treatment effect of the optimized demulsifier at different action time. The experiments show that demulsifier S1 with additive dosage of 20mg/l can accordance with the requirements of the processing very well, and as the increase of action time, the average size of droplets increase and the amount of the droplets which under 1μm decrease.

Published: June 2014

The adhesion of microorganisms to the floating cages in the aquaculture industry is currently controlled with copper as a biocide paints problem. The development of these activities has resulted in marine and freshwater sediments next to the culture centers high levels of copper. Due to these problems of environmental pollution, at present have been implemented new technologies of biological origin for the detoxification of ecosystems through the use of microorganisms (fungi, yeasts and bacteria). Therefore the main objective of this work is the search for marine microorganisms for the removal of copper. For this, samples were collected from marine sediment contaminated with copper Tenglo Channel (41 ° 29'23 .59 " S, 72 ° 58'06 .70" W). Gram negative bacterium of marine sediment was isolated in TSA medium supplemented with 7 mM Cu (II), this strain was designated as LMAE-2. The phylogenetic analysis has a 97 % similarity with Pantoeaagglomerans. The high resistance for copper was determined at 9 mM. Finally, the metal removal capacity of this bacterium was determinate in 11.6% by Atomic Absorption Spectrometry. These results suggest that marine bacteria could be a biologic model system for use in processes for removal this toxic metal.

Published: June 2014

In order to investigate the biosorption of Cu2+ by anaerobic granular sludge, the effect of equilibrium time, pH, sludge dosage, biosorption kinetics, biosorption thermodynamics and biosorption isotherms had been studied. Results showed that pseudo second-order kinetic model was useful to describe the biosorption process of Cu2+. Both Langmuir and Freundlich isotherm equations could well describe the desorption process at 15-55 °C. Thermodynamic studies showed that the biosorption process was spontaneous and endothermic in nature. When the solution temperature maintained at 35 °C, pH of 6~7, a good biosorption process could be obtained.
