There are many design challenges which must be addressed in the development of collaborative scientific discovery learning environments. This contribution presents an overview of how these challenges were addressed within Co-Lab, a collaborative learning environment in which groups of learners can experiment through simulations and remote laboratories, and express acquired understanding in a ru...

Several techniques exist to select and materialize a proper set of data in a suitable structure that manage the queries submitted to the online analytical processing systems. These techniques are called view management techniques, which consist of three research areas: 1) view selection to materialize, 2) query processing and rewriting using the materialized views, and 3) maintaining materializ...

In this paper the authors present the development of an algorithm based on the Edge Detection Technique for Automatic Detection of Brain Tumors in MR Images of the Brain and their Quantification. The basic Edge detection technique is primarily based on the abrupt changes in the intensities between the tumor and the brain regions, identified through gradient operations. This is implemented throu...

Remote laboratories that are accessible via the Internet are becoming a common phenomenon in higher education institutions. This thesis describes the iLab Service Broker architecture, a software infrastructure that supports these Internet-accessible labs by providing a number of services that facilitates their administration and management. These common services are authentication, authorizatio...

In all process Industries, to get quality product as output, the ingredients have to be composed in correct composition. So, to control quality of output product, we have to control the quantity of ingredients to be composed. In this paper, we have designed virtual Instrument which controls the process assessing the percentages of ingredients of any product using Lab VIEW. It checks whether add...

This article analyzes the role digital pioneer communities play in localization of everyday technological experimentation based on three sites practice: lab, space, and meetup. Taking a historical view, it begins with reconstruction Stewart Brand’s popularization lab discourse. On this basis, space Maker movement as well meetup Quantified Self Hacks/Hackers movements is investigated, finally ar...
