In the present work, we develop an application of the derivative concept to optimize the filtering of a colour image. This implies to optimize the value of the filter parameter to maximize performance. We propose to maximize the quality of the filtered image represented by the Peak Signal to Noise Ratio (PSNR), which is a function of the filter parameter. The optimal value for the parameter is obtained by means of an algorithm based on the approximation of the derivative of the PSNR function so that finally the optimum filtered image is obtained.","PeriodicalId":244961,"journal":{"name":"IEEE EDUCON 2010 Conference","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125210452","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}

We propose an integrated student-centered collaborative learning environment for developing communication skills, using project-based learning methods and peer assessment. In our learning environment, projects are assigned to small groups of students under teacher supervision, documented in a wiki-editing tool and presented during a public poster session. By combining wiki entries and poster presentations, we intend to facilitate students (1) to gain access to the project of their peers and share their results, (2) to analyze and comment critically the project of their peers and provide them with feedback, and (3) to enhance their writing and oral skills. Previous experiences encourage us to promote this integrated learning environment. Wiki environments allowed students to improve the quality of their projects and to develop a critical attitude towards their projects and the projects of their peers. The poster session was found to be more dynamic than traditional oral presentations. Students got engaged in a more open and critical manner with the project of their peers, and students presenting their project had the chance to improve the quality of their presentation on the fly, by presenting their work several times in the duration of the session. In future courses, we will implement a learning environment that combines both wiki-based and poster session approaches. We expect that the implementation of both approaches will help to develop the communication skills of engineering students.","PeriodicalId":244961,"journal":{"name":"IEEE EDUCON 2010 Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129586007","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}

Both aspects are very relevant to the need of keeping learning institutions as much independent as possible from software vendors. Content independence and interoperability is also required to easily share and move e-learning repositories. We propose a user friendly authoring environment based on the independent, open and XML compliant product Docbook; its simple, flexible and well structured markup make it easy to interoperate with other XML languages, particularly those related to e-learning. We are particularly interested in IMS Content Packaging and IMS QTI because they allow importing learning material into our Sakai based learning management system named PoliformaT. Docbook has also a powerful and fully customizable set of XSLT styles sheets that allow high quality web and paper delivery. The user front end is built on the commercial XML editor from XMLmind XXE. The major part of the environment is portable to other XML editors because it relies exclusively on Docbook components. At the moment the proposal presented is much more flexible, usable and productive than the available alternatives.","PeriodicalId":244961,"journal":{"name":"IEEE EDUCON 2010 Conference","volume":"162 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127555702","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}

Nowadays, with no doubt, the Internet, is the usual way to spread any kind of documentation.

These parts of the document are conformed in a unique data unit. However, even the article taking part of the congress edition, the access way to it, is made through the digital media given by the congress. So, only if some congress query media are developed, it's successly possible to access to a certain article information. The experience shown in the content of this paper gives a solution to this access problem and bases its development on the information treatment of a congress as digital learning objects. By this way, a technical paper is treated as an information unit which is composed by a data background, essentially the metadata, which are recovered and isolated in every individual documentation. Once a digital object and its metadata are disposed, congress edition conforms a structured data block, accessible not only in the congress scope but outside it. The use of metadata standards, as IEEE-LOM, let to information being built in digital platforms and repositories to be treated as congress information, as an individual article and even, some of its parts, as reusable digital objects.","PeriodicalId":244961,"journal":{"name":"IEEE EDUCON 2010 Conference","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121011942","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}

In distance education, the learning of engineering subjects has a special difficulty, which can be reduced by means of the use of new technologies, and the practice of mixed models of learning. One of these processes is the deep drawing due to its relevance in the industry. This paper presents a deep drawing tool for e-learning. The tool has been realized for its use in the Master degree because it requires advanced knowledge in manufacturing processes. The instrument has been developed with the objective of the students who can: a) Select input data for get the formability of material to deep drawing; b) Select the process that provides the best solution from a technological perspective; c) Optimize the process for saving the material; d) Know the influence of the punch in the results; e) Consideration of the process cost. The structure of the system has three subsystems: a) Solve, module for data processing and the generation of results; b) Materials, module for management data of the system; and c) Interface, module for user interaction. The tool has been implemented in the software tool programming, developed in Java. This language has been selected because it provides a methodology of object-oriented programming and its execution is possible in multiple operating systems. The paper describes each step of the tool, from the input data to final analysis and they are shown through the results given by the tool.","PeriodicalId":244961,"journal":{"name":"IEEE EDUCON 2010 Conference","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121213771","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}
