Every organization prior to adapting an enterprise solution for productivity and efficiency needs to analyze the current processes within the organization and identify the required process efficiency and quality along with the transformation needed. The Object Management Group (OMG) Product Life Cycle Management (PLM) Services 2.0 prescribes specifications based on information and computational model for engineering objects that facilitate life cycle management. Besides, this specification also provides high level scenarios for the independent model rather than specific domain. For an efficient enterprise solution using PLM system, through PLM services, there is an emergent need for business process modelling since PLM system does not cover all the business processes and which converge towards the OMG PLM Services 2.0 specification with the required business change managements. This paper highlights key modeling issues for the business processes from the perspective of OMG PLM Services 2.0 using a case study in industrial context, and proposes a methodology for the transformation of BPM towards PLM Services. The proposed methodology satisfies the business process constraints for the PLM services.","PeriodicalId":127060,"journal":{"name":"2012 15th International Conference on Computer and Information Technology (ICCIT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120935444","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}

Vaidyanathan, S. Wang","doi":"10.1109/ICCITECHN.2012.6509740","DOIUrl":"https://doi.org/10.1109/ICCITECHN.2012.6509740","url":null,"abstract":"The trend of current brain computer interfaces (BCI) seek to establish bi-directional communication with the brain, for instance, recovering motor functions by externally controlling devices and directly stimulating the brain. This will greatly assist paralyzed individuals through bypassing the damaged brain region. The key process of this communication interface is to decode movements from neural signals and encode information into neural activity. The majority of decoding or pattern classification studies have focused on cortical areas for BCIs, but deep brain structures have also been involved in motor control. The subthalamic nucleus (STN) in the basal ganglia is involved in the preparation, execution and imagining of movements, and may be an alternative source for driving BCIs. This study therefore aimed to classify patterns of deep brain local field potentials (LFPs) related to execution of visually cued movements. LFPs were recorded bilaterally from the STN through deep brain stimulation electrodes implanted in patients with Parkinson's disease. The frequency dependent components of the LFPs were extracted using the wavelet packet transform. In each frequency component, signal features were extracted using an alternative approach called neural synchronization by analyzing Granger causality between the STN. Based on these extracted features, a new feature selection strategy, namely weighted sequential feature selection (WSFS) was developed to efficiently select the optimal feature subset. A support vector machine (SVM) classifier was implemented alongside this novel feature extraction and selection strategy, and evaluated using a cross-validation procedure. Using this optimised feature subset, average correct pattern classification accuracy of movement (left or right) reached 76.0±3.1%. The results obtained in this study are encouraging and suggest that the neural activity in the deep neural circuit (basal ganglia) can be used for controlling BCIs.","PeriodicalId":127060,"journal":{"name":"2012 15th International Conference on Computer and Information Technology (ICCIT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125810345","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 antenna provides very high peak gains with lower gain variation in its operating bands. The antenna has suitable omnidirectional radiation characteristics. The dimension of the antenna is 16×18.5 mm2, which is very compact in size.

Attempts have been made to optimize the antenna performance by using a single slot in different position in patch, by increasing the number of slots in vertical and horizontal direction and by using array technique. The simulation is performed by using GEMS simulator which is commercially available antenna simulator. The antenna is designed by using Taconic TLY-5 dielectric substrate with permittivity □r =2.2 and height, h=1.588 mm. Without using array technique we have got the return losses in the range of −20 db to −25 db at the frequencies around 19.5 GHz. The series feed array offers −13db return loss around 21GHz, −17.5 db return loss around 16 GHz and −7.25 db return loss around 11.5 GHz. Therefore, this antenna is suitable for K-band, Ku-band and X-band applications.","PeriodicalId":127060,"journal":{"name":"2012 15th International Conference on Computer and Information Technology (ICCIT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115559059","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}

Detecting and recognizing these expressions comes naturally to us. But recognizing expressions is not straight forward for machines. In recent years a lot of literatures surged concerning automatic facial expression recognition. While some of these efforts have generated very good results, room for improvement still remains. There are several ways facial expression recognition can be performed. In this work we are proposing an appearance based method for extracting a new type of image descriptor based on Gabor wavelet which can be used for creating a feature vector of an image. To achieve this goal we applied Gabor filter over the image and recorded the edge response at each pixel. For each pixel we take several responses on several orientations. Finally we encode the responses and create a feature vector from the generated codes. We also showed experimental results on standard database for facial expression recognition using our proposed method.","PeriodicalId":127060,"journal":{"name":"2012 15th International Conference on Computer and Information Technology (ICCIT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130555917","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}

Then we presented an indicator algorithm which has higher accuracy compare to existing algorithms and it also provides a decision point that helps the investor to understand the significance of the result of the indicator. Finally we applied association rules mining to group the selected (based on precision) indicator algorithms to come up with a model to increase the overall accuracy.

Providing reconfigurability, the architecture enables the user to choose one of the existing techniques according to the level of security required. So the designed architecture is both flexible and reliable enough for the user to secure their privacy of conversation or e-commerce transaction.

But, in the arena of electronic devices, tools for Bangla writing are inadequate. Also, there are limitations for typing Bangla faster in an efficient way because of the lack of proper layout. After forty-one years of the liberation war, an optimal and widely accepted Bangla keyboard layout has not yet been obtained. And in present days, smart-phones and tabs are being used profoundly where soft keyboard is the most essential input method. In Bangla soft keyboard, the arrangement of letters should be in such a way that paves the way towards an easy and efficient text input method. Our primary evaluation shows a significant improvement in typing speed, ease of learning and reduction in error rates. Hence we propose an efficient Fixed Bangla Keyboard Layout where Bangla alphabets are mapped phonetically on the standard QWERTY keyboard and a Bangla text-to-image replacement technique for non-Bangla supported smartphones. In this paper we present a soft keyboard implemented on Android platform using this layout with text-to-image conversion support.","PeriodicalId":127060,"journal":{"name":"2012 15th International Conference on Computer and Information Technology (ICCIT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120882153","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}
