This study is an attempt to apply Rasch Measurement in the field of technology to assess Information Professionals’ (IP) competency. Bloom’s Taxonomy is used as the framework for assessment whilst utilising Rasch model in constructing the measurement in evaluating the competencies. Assessment only generates raw score and need to be transformed into meaningful measurement values. Rasch model measurement enable tabulation the IP; person and, a given task; the items, on a distribution map (PIDM) on a common scale termed logit. It gives a more accurate estimate of the IP’s achievement on a linear scale of measurement. Comparative analysis against the traditional histogram tabulation and simple mean shows that Rasch measurement was found to give a better exploratory depth in understanding the ability of each IP. Despite the small sample size, the IP were clearly categorized according to the respective workgroup cluster, knowledge and skills. This leads to a new paradigm in assessing competency of IP individuals using Rasch model. A new descriptive scale is developed to classify IP’s by class intervals as measured by Rasch Model.","PeriodicalId":314159,"journal":{"name":"2008 International Symposium on Information Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130952563","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 paper presents the design of a complete display unit for Arabic alphanumeric characters using uniform segments. The word ‘complete’ signifies that the proposed display unit can represent all forms of entire Arabic alphabets as well as Arabic numerals. The word ‘uniform’ is used because of avoiding curved segments. The first segmented display unit for Arabic characters in the world covered only the isolated form and did not follow any base line to display a sequence of characters. This work extends the capability to represent all the forms of Arabic characters and follows a base line to represent a sequence of characters. Here a grid structure of 25 non-overlapping segments has been discovered. There can be 109 alphanumeric characters (at least 99 characters such as isolated form- 30, final form-29, medial form- 21, initial form- 20; and 10 numerals) to be displayed and 7-bit input is used to represent each character. After analyzing appropriate segments to be activated for every character, respective logic functions of all segments have been derived to display the entire set of Arabic alphanumeric characters.","PeriodicalId":314159,"journal":{"name":"2008 International Symposium on Information Technology","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131130379","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 system functions as a decision support system to help users the potentiality of investment in MEMS industry by predicting future sales and profitability based on past knowledge. In this paper work fuzzy logic system (FLs) is proposed, as it is conveniently adaptable to solve such problems. Among the many factors that are important for predicting MEMS industry potential, are sales, price, profit, earning, P/E ratio, PEG, P/S ratio. Some of these factors may be related, but some act independently. These factors are combined together into a finalize result. Data Fusion is the process of combining multiple economic factors in order to produce information of tactical value to the user. Briefly, in this project, the behaviour of an intelligent system is simulated by the fuzzy logic toolbox. In fact, the output variable and valuation scale is dasiainvestmentpsila. It is fuzzy variable and compared this output rate with actuality.","PeriodicalId":314159,"journal":{"name":"2008 International Symposium on Information Technology","volume":"41 25","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131500763","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 taxonomies are built via FCA using syntactic dependencies as attributes such as verb/head-object, verb/head-subject and verb/prepositional phrase-complement. This paper discusses the overall process of learning taxonomy using FCA with the same syntactic dependencies as the English language which is then applied on Malay texts. Malay, an Austronesian language follows the same Subject-Verb-Object sentence structure like English but syntactically different. The result shows a lower recall and precision compared to related work in other languages. The poor result is caused by several factors such as the selection of smoothing technique. The experimental result indicates that the current smoothing technique with FCA does not produce good results. Therefore, as an addition to the syntactic dependencies, we used linguistic pattern such as Hearst’s pattern in finding similarities between terms. We compare the results of our technique against the cosine used in the FCA-based taxonomy learning approach. The proposed technique attains both higher precision and recall than the previous technique.","PeriodicalId":314159,"journal":{"name":"2008 International Symposium on Information Technology","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123772437","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}

Peer-to-peer (P2P) is one of the architecture that promising scale and dynamism environment. In this paper, we present a P2P model for Scientific Data Grid that utilizes the P2P services to address those problems. For the purpose of this study, we have developed and used our own data grid simulation written using PARSEC. In this paper, we illustrate our P2P Scientific Data Grid model, our data grid simulation and the design of proposed data replication strategies. We then analyze the performance of data discovery service with and without the existence of replication strategies relative to their success rates, response time, average number of hop and bandwidth consumption. The results from simulation study that show how the proposed replication strategies promote high data availability in the proposed Scientific Data Grid model and how these strategies improve the discovery process are presented.","PeriodicalId":314159,"journal":{"name":"2008 International Symposium on Information Technology","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122416916","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}

One of the major underlying problems in this field is amount of water consumption. A principle challenge many hospitals face is in identifying the way of water waste and reducing its consumption. In this research a modification in cooling trap of autoclaves is presented. Also related efficiency evaluated through direct measurement of water consumption. Correlation of data and measurement implies that using water saving system in steam sterilizers reduce more than 60 % water waste as an average, Although it directly depends on the type of autoclaves. In this case gravity autoclaves compared with vacuum type. It was seen applying water saving systems to vacuum autoclaves brought better results than gravity types. It is also concluded, retrofitting sterilizers with water conserving system was determined to be a very cost effective water conservation measure for Iranian private hospitals. Payback is expected to be less than 3 months, dependant upon initial constant water flow of the sterilizers being retrofitted, hours of operation (including standby), and the level of incentives provided by the utility","PeriodicalId":314159,"journal":{"name":"2008 International Symposium on Information Technology","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121145228","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}
