There exists several models for the simulation of vascular flows; they span from simple circuit models, to full three dimensional ones which take into account detailed features of the blood and of the arterial wall. Each model comes with benefits and drawbacks, the main denominator being a compromise between detailed resolution requirements versus computational time. We first present a fluid-st...

Mark Warschauer's Laptops and Literacy: Learning in the Wireless Classroom has eight chapters that build upon one another to show how the incorporation of technology, specifically laptops, could work to increase literacy rates. Warschauer looks at ten schools in Maine and California to show how laptops help improve literacy in the classroom. He wrote his book based on the action research he con...

Students often have their own individual laptop computers in university classes, and researchers debate the potential benefits and drawbacks of laptop use. In the presented research, we used a combination of surveys and in-class observations to study how students use their laptops in an unmonitored and unrestricted class setting—a large lecture-based university class with nearly 3000 enrolled s...

Recent trends are that resource rich laptops are ubiquitous and are becoming the primary computing platform for many users. USA today [2] described the emergence of about 30 million (American) nomadic users. Gartner Dataquest predicted a yearly growth of 10% of these users. Newer laptops are also boasting resources as high as 2.6 GHz dual core processors, 320 GB of storage, 4 GB of memory and 3...

26 ABSTRACT With the increase in the use of portable devices in the present era, there arises a need to develop greener and more efficient methods of generating energy to power these devices. Despite vacuum tube electronics’ weight and large associated battery, people living in the early 1900s have lugged such enormous “portable” radios to picnics and other events off the power grid. As electro...

The article gives an account of the “Handheld-Mode Interface for the OLPC XO Laptops” research work within OpenUsability project. The introduction of the following document expounds what the OLPC XOs are and which our research task has been. The second chapter explains the three stages of the work, from the concept to the graphic design. The achieved results are briefly summed up in the conclus...
