field police officers operating in the district of Groningen North (Netherlands), equipped with PDAs through which they ubiquitously access information while on the move; students of the Massachusetts Institute of Technology (i.e. MIT, USA), equipped with laptops in a campus where wireless Internet connectivity is ubiquitous; all subscribers and roamers using their mobile phones in the Amsterda...

Mobile computational devices, like smartphones, tablets and laptops, have become a standard part of the computing landscape. Moreover, many users regularly interact with an assortment of devices, including mobile ones. Therefore, the ability to migrate UIenabled applications is becoming increasingly important. We describe a design-pattern for applications to simplify support for usersession mig...

We present the design and implementation of CGD, the CryptoGraphic Disk driver. CGD is a pseudo-device driver that sits below the buffer cache, and provides an encrypted view of an underlying raw partition. It was designed with high performance and ease of use in mind. CGD is aimed at laptops, other single-user computers or removable storage, where protection from other concurrent users is not ...

This paper presents a multimedia platform for digital television based on existing single purpose open-source solutions. The advantage of the proposed platform regarding existing ones is the possibility to integrate new features or change existing ones (e.g., recording format and coding standard). In this sense, the proposed terminal natively supports: (i) multi-user remote management; (ii) bro...

This paper presents high-level details of two contributions to iperf, a modern tool for testing network performance. The first contribution is a port of the tool to the Windows Mobile operating system, while the second one is the extension of the tool to support BlueTooth communication. The paper also includes results of experiments carried out by the modified tool in various configurations of ...

You may refer to the textbook, lecture notes, Matlab ® tutorials, and other class materials as well as your own notes and scripts. You may use a calculator (for simple arithmetic operations and function evaluations). However, laptops, tablets, and smartphones are not permitted. You have 30 minutes of recitation to complete the mini quiz. When you are finished, you can hand in your quiz and star...

As we head into the 21 century, organizations must consider information threats. Simply, step one would be that all-sensitive data should be classified as important and relevant access restrictions and granular protection should be enforced. Or consider that all laptops, desktops, and peripherals should be physically and logically secured after business hours. Most importantly, users should be ...

The Chip Multiprocessor (CMP) will be the basic building block for computer systems ranging from laptops to supercomputers. New software developments at all levels are needed to fully utilize these systems. In this work, we evaluate performance of different highperformance sparse LU factorization and triangular solution algorithms on several representative multicore machines. We included both P...

In diesem Vortrag wird der Einsatz von Squeak-Etoys im Bereich der Primarstufe vorgestellt. In verschiedenen Ländern gibt es Pilotprojekte, die sich mit dem Einsatz von Computern in dieser Alterstufe befassen. Durch die Verbreitung der XO-Laptops wird in vielen Ländern mit Etoys gearbeitet. In diesem Beitrag wird untersucht, wie sich Etoys in die Rahmenbedingungen und Lehrpläne der jeweiligen L...
