This paper explores how tactile feedback can support cyclist in order to fulfill user-defined training programs. Therefore, actuators are integrated in cyclists’ shoes. The rhythm the cyclist should pedal is communicated via tactile feedback so that the heart rate is kept in an interval which is, for example, optimal for increasing stamina. After a preliminary study, which was used to gather th...

In a web group-learning environment, students must communicate with other group members on the Internet to accomplish group projects and share knowledge. Communication is likely to affect performance and so analysing the relationship between communicative relationships and group performance may help teachers to monitor groups effectively. Certain tasks are necessary to perform such an analysis ...

Recently, a renewed interest arises in the application of nanotechnology for the upstream petroleum industry. In particular, adding nanoparticles to fluids may drastically benefit enhanced oil recovery and improve well drilling, by changing the properties of the fluid, rocks wettability alteration, advanced drag reduction, strengthening the sand consolidation, reducing the inter-facial tension and...

Appropriately designed web based learning materials are thought to be more efficient than traditional ones because of interactivity and multimedia, which enable clear explanations, motivating design, active learning, instant feedback and other advantages. Our research question is whether students achieve better learning results if they learn from web based learning materials than from tradition...

1 In this paper we present a multilingual application for speech technology. The SpeeData project aims at building a demonstrator that provides a user-friendly interface for spoken data-entry in two languages: Italian and German. The application domain is the land register of an Italian region in which both languages are o cially spoken. The considered data-entry task is particularly challengin...

many countries have created systems for monitoring food products. however, these systems need paper and label and also, cannot find the origin and final destination of food product. radio frequency identification (rfid) has the capability of monitoring foods completely and track the mentioned points. this technology also can monitor many food products simultaneously. the usage of this system ca...

High-technology projects are known as tools that help achieving productive forces through scientific and technological knowledge. These knowledge-based projects are associated with high levels of risks and returns. The process of high-technology project and project portfolio selection has technical complexities and uncertainties. This paper presents a novel two-parted method of high-technology ...
