The Web Geometry Laboratory (WGL) project's goal is to build an adaptive and collaborative blended-learning Web-environment for geometry. In its current version (1.0) the WGL is already a collaborative blendedlearning Web-environment integrating a dynamic geometry system (DGS) and having some adaptive features. All the base features needed to implement the adaptive module and to allow the integration of a geometry automated theorem prover (GATP) are also already implemented. The actual testing of the WGL platform by high-school teachers is underway and a field-test with high-school students is being prepared. The adaptive module and the GATP integration will be the next steps of this project.

LTE has been identified as a new wireless standard by the 3rd Generation Partnership Project (3GPP) which is using the VoIP to transmit the voice services and packet the data for all services. Traffic scheduling plays an important role in LTE technology by assigning the shared resources among users in the most efficient manner. The main objective of this paper aims to design an efficient scheduling algorithm for LTE standard. It can not only obtain the high system performance but also maintain the proportional fairness. Each user is allocated the requested resource according to the predefined QoS parameters. The scheduling algorithms performances on the downlink were measured using a MATLAB based system level simulation.

Abstract-In order to achieve the everywhere at anytime Internet, connection to the network must be available even inside cars, trains and buses, without disruption of service. In order to reach this objective, intelligent communications are now considered necessary and will play an increasing role in the modern Transportation Systems. As train speeds increase, wireless communications between devices on the train and the outside encounter difficulties, and maintaining communication quality is a major challenge. This paper, propose a new multihomed solution for transparent internet access in trains through secure handoff anticipation.
