engineeringproblems, engineering education needs reform. Multi-university system education (MUSE) is aproject sponsored by the National Science Foundation as a step toward engineering educationreform. The goal of this project is to develop innovative approaches for engineering education.They have proposed a learning model that develops important skills that is not addressed in thecontemporary engineering curricula. This model’s emphasis is to teach system thinking skills toundergraduate students. Systems thinking enable students to envision the architecture ofcomplex, multi-layered engineering systems13.In this project, an undergraduate track in wireless sensor networks has been developed as avehicle for studying these systems, featuring (1) junior-year

The Government owned NBN Co has been tasked to “…deliver Australia'sfirst national wholesale-only, open access broadband network to all Australians, regardless ofwhere they live”2. The project aims to connect 93% of premises using Fibre to the Home (FTTH)technology and the remaining 7% of premises using terrestrial fixed wireless or satellite wirelesstechnology. Providing a national broadband network and particularly FTTH will have a majorimpact on education, health, business, government service delivery and many other areas.19 Table 1: Internet Access Options

It uses an SQL based database whichallows the traceable evolution of both the schema and the content data. Some light transactionalsemantics introduced to the system to trace and follow changes to the database over time andsecure the data at multiple levels at the user, database, OS and network levels.

We demonstrate positiveCS student perceptions of the methodology and similar JiTT-related student responses in thethree courses. The method appears effective in increasing student ability and willingness to workindependently whether in introductory or advanced courses.1. INTRODUCTIONWe describe an experiment that compares the use of the Just-in-Time Teaching (JiTT) [1]methodology in a high level Computer Science course with its use in two introductory Physicscourses at a middle-sized Liberal Arts university. We examine student perceptions of this newmethod across the three courses involved in the experiment. JiTT

The purpose ofusing SCADA in critical infrastructures “is to allow operators to monitor and control systems”and to ease workload and management[3]. The architecture of these systems can consist of vastarrays of components. In some cases, SCADA systems are large enough to

Arrays can beconsidered as fixed-length entities, although at times an array reference with proper syntax maybe reassigned to a new array of a different length. On the other hand we have dynamic datastructures, 1 such as stacks, queues, trees and lists that can shrink or grow as programs execute.Android also

We believe our experiences and results will be useful for other educators seeking to efficiently use limited physical hardware resources to develop an effective course in high performance computing systems.1 IntroductionDeveloping and deploying Beowulf-style high performance computing clusters has always been adifficult process for many reasons. Traditionally, Beowulf-style HPC clusters consist of a largenumber of computing nodes, and each of those nodes needs to have an operating systeminstalled on it. To complicate matters, some HPC jobs require Microsoft Windows, which

The first twocomments, which praise the author’s work with adjectives such as “good” and “correct”, whentaken independently, do not contain any information that could help authors improve their work.Reviews aid in the decision making process, whether it is a student’s grade or the decision toaccept or reject a scientific paper.

Design the computer software to control the solar tracker (or multiple solar trackers) remotely via the Internet using the User Datagram Packets (UDP) protocol.2. Design the communication protocol that will be used to send commands from the master controller computer to the remote controller computer.3.

The core of text-based search is supported by the theories andpractices of an academic branch in computer science or information science called
