Service Oriented Architecture (SOA) standards has been used to implement virtual organizations. Transformation in computing paradigms and software tools with the passage of time has introduced modern ways to achieve the said targets. Reference Architecture for Virtual Organization (RAVO) was proposed as a standard for VOs [1]. RAVO is based on XaaS (Every-thing-as-a-Service) approach and is presented as a layered model. From software engineering perspective, different patterns can be adopted for implementation. Onion architecture is one of the emerging architectures based on the dependency inversion principle. The paper presents the RAVO as an Onion architecture and a prototype for formal organization by decoupling all of its components. The components are encapsulated inside one another. This approach extends and makes it easy for Software Engineers to implement a standard VO system. It is safe to say that this decoupled approach to implement RAVO, can be used as a strong point of reference in software development.","PeriodicalId":194801,"journal":{"name":"2016 13th Learning and Technology Conference (L&T)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114983582","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}

Presented work offers a character recognition system for cursive script (e.g., Arabic, Urdu, etc.) segmented characters from their images. Presented methodology consists of phases namely (1) Image Acquisition, (2) Preprocessing, (3) Chain Code Formation, (4) Signal Generation, and (5) Pattern Extraction. Image Acquisition takes an image of segmented character and converts it into binary image. Preprocessing finds out unconnected regions from the binary image and separates into one main region and one or more secondary regions. The secondary regions make vector of features whereas main region is further converted to one pixel wide thinned image. Chain Code Formation finds out chain code vector using 8-directions. Finally Pattern Extraction uses a defined algorithm to form qualitative signal pattern describing increase (+1), decrease (-1), and constant (0) pattern of writing layout. Additionally recognition of the character is carried out through Feed-Forward Neural Network (FFNN). The methodology and presented algorithm are evaluated using 1292 images of segmented characters of 271 different ligature classes of printed script. The methodology is tested on MATLAB and overall recognition rate obtained with Mean Squared Error (MSE) of 0.0014 with 60 hidden neurons of FFNN.","PeriodicalId":194801,"journal":{"name":"2016 13th Learning and Technology Conference (L&T)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130981280","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 ultimate goal of the project is to create engaging math learning models that will make the learning environment fun and attractive. The main goal of the project is to develop effective math learning models and use them to enhance students' performance. By applying Maple, a cutting-edge Computer Algebra Systems (CAS), and other digital tools (Tablet PC's) for teaching and learning of mathematics, these models can: (1) make mathematics learning interesting and meaningful while still covering the original contents; (2) simplify abstract mathematics concepts and make them easy to understand; and (3) bridge mathematics and science and motivate students to seek science careers. In class room we use Microsoft OneNote on the Tablet PC and combine it with a Digital Projector. Maple 3D graphs are easily imported to class notes and we can archive and share our lecture notes. The models are carefully designed to provide students with the chance to explore mathematical issues that are infeasible to address in the classroom and improve their performance in mathematics and prepare them to for advanced science and engineering courses. The model also balances this capability by allowing students to modify selected parts of the MPLE worksheet for a given problem and guide them to design new procedure, and are thus get them to use Maple features to perform application tasks. We also explore whether using these tools will positively affect student engagement in the classroom in addition to aiding them in the long term development of a deep conceptual understanding of mathematics.","PeriodicalId":194801,"journal":{"name":"2016 13th Learning and Technology Conference (L&T)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133515547","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}
