INTRODUCTION

Valencia, a place to visit

Introduction• Universidad Politécnica Valencia (UPV)

– Public academic institution since 1971– A leader in the use of Technical innovation– Official and non-official studies– Post – Graduate studies

• The UPV in numbers– 4 Campuses– 15 Colleges– 40 Research centers– 40 Official Degrees– 20 post graduate studies– 40.000 Students– 2.600 Teachers– 1.400 Staff

Sakai in the UPV

• Pilot running during 2006– Full capabilities– Selected group of users

• Full production System in 2006/2007– Based on the 2.1.2 version – Customized to university requirements– Integrated with SSO– Integrated with enrollment system– 4.000 sites and 40.000 students

MATLAB

What is MATLAB?

• An interactive environment to perform computationally intensive tasks.

• Wide range of applications: signal and image processing, communications, etc.

• Provides functions for calling Java classes.

MATLAB BUILDER FOR JAVA

• Matlab project• Components• Classes and methods

MATLAB BUILDER FOR JAVA

• How data are handled?– Input data conversion– Function signatures generation– Data returned are not converted to Java types

MATLAB BUILDER FOR JAVA• What happens in the build process?

– Java code for the component implementation

– Java code compiltation– Matlab component technology file generation– jar file with Java classes (mycomponent.jar)

myclass.java -> Contains a Java class with methods encapsulating the M-functions specified in the project for that class.mycomponentMCR.java -> Contains the CTF decryption keys and code to initialize the MCR for the component

PROJECT DESCRIPTION

Objectives• Enable virtual laboratories creation for self-experimenting based in high level

environments (i.e.Matlab).• Learning objects generation accesible via Internet• Easy-to-use tool/service• TODO: reusable LO repository
