Wireless sensor networks (WSN) are an ad hoc network consisting of miniaturized autonomous sensors that communicate with each other over a radio link. In this paper, the authors' contribution is a cross-layer approach. To achieve this approach, the authors proposed in the first part an improvement of LEACH algorithm named WEIGHTED_LEACH. This…

In this paper, the authors propose a novel forwarding strategy based on deep learning that can adaptively route interests/data packets through ethernet links without relying on the FIB table. The experiment was conducted as a proof of concept. They developed an approach and an algorithm that leverage existing intelligent forwarding approaches in…

Classroom activity traditionally takes one of three forms, variously oriented toward the levels of individual students, small groups, or the whole class. CSCL systems, however, may enable novel ways to facilitate instruction within or sequence activity across these different levels. Drawing on theoretical accounts of learning at and across…

For many the phrase "teaching math online" evokes a vision of teaching and learning that is not based in physical classrooms. Perhaps teachers and students are even interacting asynchronously. In math classrooms in the United States, the increasing availability of devices (e.g. laptops, Chromebooks™, smartphones, and tablets) and…

Agile methodologies have become increasingly popular among software developers as evidenced by industrial participation at related conferences. The popularity of agile practices over traditional techniques partly stems from the fact that these practices provide for more customer involvement and better accommodate rapidly changing requirements,…

LYDIAN is an environment to support the teaching and learning of distributed algorithms. It provides a collection of distributed algorithms as well as continuous animations. Users can combine algorithms and animations with arbitrary network structures defining the interconnection and behavior of the distributed algorithm. Further, it facilitates…

This paper examines the design and evaluation of a TV on Demand (TVoD) system, consisting of a globally accessible storage architecture where all TV content broadcast over a period of time is made available for streaming. The proposed architecture consists of idle Internet Service Provider (ISP) servers that can be rented and released dynamically…

Describes the design, construction, administration, and results of networked campuswide placement testing for mathematics and chemistry at Stanford University. Reasons for online testing are discussed; software requirements and programing details are explained; and the impact on students and their advisors is considered. (Contains seven…

Discusses the distribution of curriculum ideas over the Internet. Considers the need for productivity software for curriculum development by classroom teachers, and introduces "Teacher's Curriculum Assistant," software designed for this purpose. Describes a constructivist curriculum and provides an example of a problem-solving…

Examines the effects of participation in the Fifth Dimension after-school computer program on far transfer achievement in the subject areas of reading and math. Provides evidence that children who participate in the Fifth Dimension master knowledge and skill structures and acquire practices that mediate their performance on global measures of…

Describes Internet use for electronic mail projects in elementary education. Discusses typing directly versus composing offline, and the effect of electronic letter-writing activities on improving grammar, spelling, social studies, science, and mathematics skills. (AEF)

This case study considered the syllabus of the first and second year studies in computer science. The aim of the study was to reveal which topics covered in the syllabi were really needed during the following years of study or in working life. The program that was assessed in the study was a Masters program in computer science and engineering at a…
