The proposed filter has a fundamental bandwidth of 1.6GHz with fractional bandwidth (FBW) of 29.7% centered at the 5.4GHz band, and second bandwidth of 300.0MHz with FBW of 3.6% centered at the 8.15GHz band. The basic dual-wide bandwidth is attributed to the interaction of the novel modified polygon pair and upper stub loaded stepped impedance resonator. Moreover, the added down stub loaded stepped impedance resonator (SLSIR) further enhances the pass band performance by widening the bandwidth and optimizing reflection coefficient performance considerably. To validate the proposed ideas, the multi-standard filter is designed and simulated by Ansoft HFSS software. The simulated results agree well with the theory predictions. The featured broad bandwidths over two frequency bands and the miniaturized size of the proposed filter make it very promising for applications in future multi-standard wireless communication.","PeriodicalId":161782,"journal":{"name":"2015 Internet Technologies and Applications (ITA)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124059306","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}

Each antenna is represented in the form of crescent-shaped monopole structure. The lengths of the two arcs are designed to resonate at 2.45GHz, and 3.5GHz to meet the requirements for the WLAN and WiMAX standards respectively. The two monopoles have a small separation distance of 9mm (i.e., 0.0735λ0 at 2.45GHz). A new technique is proposed for the reduction of the mutual coupling between two closely-spaced antennas by etching a slot in each of the feed lines of two the antennas. The slots are folded to the shape of the letter S to conserve length of the feedlines. In each antenna, the slot is tuned to resonate at the operating frequency of the other antenna so that the other frequency is notched out. The antenna performance was investigated by simulation using CST Microwave Studio software. The results show that the proposed method has reduced the envelope correlation coefficient by 35 folds at the 2.45 GHz, and 21 folds at the 3.5GHz frequency bands. Measured S-parameters verified the simulated results.","PeriodicalId":161782,"journal":{"name":"2015 Internet Technologies and Applications (ITA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132098665","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 problem suffers from a serious drawback because, for many instances, the target behavior cannot be achieved. In that case, the user is responsible for bringing changes until the problem becomes solvable. This inherent limitation is due to the fact that an exact match is required between the actions initiated by the user and those offered by the available behaviors. The main question is, how can a controller select a suitable behavior such that the functionality of one of its available actions is close to that currently requested by the desired target behavior? This paper provides an answer to this question by associating semantics to actions based on expectations and exploiting a semantic similarity function between actions. Similar actions that have different names, but comparable tasks, are considered equivalent. This renders the behavior composition framework more flexible so that it can fit with semantic environments.","PeriodicalId":161782,"journal":{"name":"2015 Internet Technologies and Applications (ITA)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122773806","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}

Any attempt aimed to represent such complexity can be facilitated by referring to appropriate semantic knowledge bases, able to structure the domain concepts along with the relationships between them. Such consideration can be particularly applied to the Model-Driven designing phases of a software system, and especially within the User eXperience - UX - modelling process. In effect, the UX modelling is becoming more and more dominant, even with the advent of Rich Internet Applications - RIAs. They represent particular web applications that are capable to provide features and functionalities of traditional desktop applications. This paper introduces a Knowledge-Driven framework for the UX engineering process based on the interaction with a domain knowledge base, along with a prototype generator. Such framework is obtained by extending and by adapting an existing one, the IDM Editor, which performs the UX reengineering of a legacy application, using the methodology Interactive Dialogue Model - IDM.","PeriodicalId":161782,"journal":{"name":"2015 Internet Technologies and Applications (ITA)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123425485","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}
