We present a learn by example system being developed in the University of Aveiro. This system uses the software platform, PeA, of the project PmatE, which provides a way to store and run our example questions (more precisely question generator models). Several PeA models for the course “Cálculo III” (calculus with several variables), have been produced recently. The contents of the course is di...

Breast cancer is the most common cancer in the world and the most common cause of cancer death in women. Treatment of breast cancer is currently effective only if it is detect at an early stage. X-ray mammography is the most effective method for early detection .In this paper authors have propose Computer Aided Diagnosis (CAD) System for breast cancer using mammography images. Moreover ,authors...

Purpose: According with the principles of impartial evaluation of the students’ knowledge, with the national trends in ensuring the efficient and effective end-of-course evaluation, the authors developed an original computer-assisted examination system. Materials and Methods: The information discussed at courses and laboratory class, for the Physical Chemistry Course and for the Microbiology an...

objectives : the purpose of this in vitro study was to compare the marginal adaptation and fracture resistance of a zirconia-based all-ceramic restoration with two preparation designs. materials and methods: twenty-four mandibular premolars were randomly divided into two groups (n=12); the conventional group received a peripheral shoulder preparation and the modified group received a buccal sho...

RATIONALE AND OBJECTIVES Accurate segmentation of brain tumors, and quantification of tumor volume, is important for diagnosis, monitoring, and planning therapeutic intervention. Manual segmentation is not widely used because of time constraints. Previous efforts have mainly produced methods that are tailored to a particular type of tumor or acquisition protocol and have mostly failed to produc...

Computer Aided Method Engineering (CAME) is a kind of computerized tool for supporting the processes to build project-specific methods for information system development. One of the easiest ways to build them is to adopt reuse technique. In this technique, we have a kind of database system, called method base, which stores reusable method portions, and assemble them into a project-specific meth...

Accurate measurement of clot thickness, hematoma area, and location on MRI scan have been successfully executed which is important because of need for accurate and rapid diagnosis and treatment, prompt transfer of the patient to a facility capable of MRI scanning and neurological intervention is necessary. Automated systems for analyzing and classifying medical images have gained a great level ...

This paper describes the embedding of a statistical translation system within a text editor to produce TRANSTYPE, a system that watches over the user as he or she types a translation and repeatedly suggests completions for the text already entered. This innovative Embedded Machine Translation system is thus a specialized means of helping produce high quality translations. 1 I n t r o d u c t i ...

Computer Aided Assessment (CAA) tools are more and more widely adopted in academic environments mixed to other assessment means. In this paper, we present a CAA Web application, named eWorkbook, which can be used for evaluating learner’s knowledge by creating (the tutor) and taking (the learner) on-line tests based on multiple choice, multiple response and true/false question types. Its use is ...

In this era of globalization, learning multiple languages is becoming necessary. Learning to speak a new language involves knowing how to correctly pronounce words. In many cases, corrections to pronunciation mistakes come from language teachers who can typically give students only limited time and attention. With the rapid development of automatic speech recognition (ASR) technologies, compute...
