Throughput performance of the integrated network is improved by reducing handoff delays and packet losses. We also decrease the system energy by estimating user locations in comparison with the WLANs to decrease interface ontimes. Performance and delay results are presented to demonstrate the effectiveness of the proposed scheme.","PeriodicalId":329489,"journal":{"name":"2009 International Conference on Computer Engineering and Technology","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126485428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The basic subject of simulation is the probabilistic approach to describing real world uncertainty. However, in many cases we do not have information that would be precise enough to build the corresponding probabilistic model or there are some human factors that prevent doing so. In such conditions the statistical and mathematical tools of fuzzy set theory may be successfully used. This paper applies t-test for validating the results obtained from conventional simulation and fuzzy simulation in comparison with the actual data of manufacturing system. Then, we use fuzzy simulation to improve the performance of manufacturing system by considering production constraints, system limitations and desired targets. The design of fuzzy simulation is discussed for an actual and large multi product assembly shop.","PeriodicalId":329489,"journal":{"name":"2009 International Conference on Computer Engineering and Technology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115157857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This code is constructed using code segment and data segment. One of the important properties of this code is that the cross correlation at data segment is always zero, which means that Phase Intensity Induced Noise (PIIN) is reduced. For the performance analysis, the effects of phase-induced intensity noise, shot noise, and thermal noise are considered simultaneously. Bit-error rate (BER) performance is compared with Hadamard and Modified Frequency Hopping (MFH) codes. It is shown that the system using this new code matrices not only suppress PIIN, but also allows larger number of active users compare with other codes. Simulation results shown that using point to point transmission with three encoded channels, RD code has better BER performance than other codes, also its found that at 0 dbm PIIN noise are 10-10 and 10-11 for RD and MFH respectively.","PeriodicalId":329489,"journal":{"name":"2009 International Conference on Computer Engineering and Technology","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127117288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present work is an attempt to develop a systematic procedure for selection of robot based on an integrated model encompassing the manipulator attributes and manipulator requirements. The developed procedure can advantageously be used to standardize the robot selection process with view to perform a set of intended tasks.

We also find the process of knowledge transfer though the whole ISD project life circles by case study. The results showed that in different stage of project life-circle, the transfer intensity of every kinds of knowledge are different. Domain and business process knowledge are what vendors lack of most according to the current situation of knowledge base for vendors in China. They can accumulate lots of know-how through cooperation with clients in western markets from different vertical industry. We also proposed key factors impacting the effectiveness and efficiency of knowledge transfer in real-life ISD offshoring outsourcing project, which are project character (novelty, customization, complex), client character (firm size, interaction participation, process maturity), client-vendor related character (communication quality, knowledge overlaps, prior cooperation experiences) and vendor character(firm size, work dispersion, absorb ability, culture fit). Among those factors, most of the respondents emphasis that communication, understanding and culture fit are what they most concern of knowledge transfer in onsite-offshoring/dispersed setup. The managerial implications derived from our knowledge transfer framework may help guide vendors pay more attention on the training of culture and communication skills for the employee.
