User request trace-oriented monitoring is an effective method to improve the reliability of cloud systems. However, there are some difficulties in getting traces in practice, which hinder the development of trace-oriented monitoring research. In this paper, we release a fine-grained user request-centric open trace data set, called Trace Bench, collected on a real world cloud storage system deployed...
The Remote Laboratory Management System (RLMS), REMLABNET, for the integrating and management of remote experiments for starting university level and secondary schools, is presented. Its building was initiated both from the extensive use and expertise in Internet School Experimental System (ISES), remote experiments built and the lack of a similar system for secondary schools in Europe. RLMS is built...
In this paper we present a model to control the instruments and experiments in a remote laboratory using a low cost control architecture. This model is based on a LAN network and a control methodology through reusable drivers. The objective is to obtain a software control architecture independent of the hardware of the laboratory, so each institution can deploy its own solution according to the available...
Remote Access Laboratories have been successfully installed around the world enabling students to practice practical skills and develop their knowledge through experimentation. Remote laboratories have the advantage of being accessible from anywhere anytime allowing users more flexibility and mobility. Typically installations are designed to resolve issues of access or utilization. Clear pedagogical...
In the traditional cockpit display-control system, pilots have to face more and more instruments and response to the complex information simultaneously. In order to study the change characteristics of the mental workload under such multi-task condition, take the virtual instruments for design objects to set up a series of tasks. With the increase of information quantity and frequency of m instruments,...
This paper introduces a new form of collaboration between school and family through the Electronic Handbook developed in our research work, which makes more effective the communication between both. Today is consensual in education sciences consider that collaboration between school and family is a key component in the process of learning and educational success. With the Electronic Handbook, the...
The use of Internet Laboratories (iLabs) at Makerere University has gained momentum, enabling students to conduct remote experiments on physical equipment. iLabs are based on the Massachusetts Institute of Technology (MIT) iLabs Shared Architecture (ISA) which consists of three tiers: labserver onto which the hardware is connected; the client which is an interface that a user interacts with; and the...
The driver development is important for the program-controlled instruments. The purpose of this paper is to introduce how to develop the drivers, which can realize the aim of interchangeability the same type of instrumentation without replacing the drivers, so the application layer can call it conveniently. The drivers are developed under the Interchangeable Virtual Instrument standards, which is...
Compared with the traditional local IDE, online IDE provides a no-install programming environment. The proceeding in this area is attracting more and more researchers' focuses. Although online IDE can bring developers a lot of convenience for developing process, it also suffers from some special challenges. While most current research work focuses only on the implementation of basic features, some...
Web-based laboratory has become a useful tool in Engineering and Science education. Many educational institutions now days use web-based laboratory technology to conduct laboratory experiments for their students. This paper discusses the implementation of interactive Digital Electronics laboratories designed and implemented at University of Dar es Salaam. Particularly, the implementation of Decoder...
Fundamentals of electronic circuits' practices have a central role in all the electrical engineering education disciplines. They teach the student the basics of electronic circuit's components and the adjustment of electrical instruments, and allow him to wire and build circuits in order to realize and monitor measurements. Unfortunately, and despite the importance of this type of practices, they...
Practical sessions are the backbone of qualification in engineering education. It leads to a better understanding and allows mastering scientific concepts and theories. The lack of the availability of practical sessions at many universities and institutions owing to the cost and the unavailability of instructors the most of the time caused a significant decline in experimentation in engineering education...
This paper discusses a new technology for making electric and electronic circuit experiments remotely. Virtual Instrument System in Reality (VISIR) has been implemented at the Spanish University for Distance Education (UNED) for new engineering grade's distance laboratories. It gives a brief update of the project and its implementation, on the other hand, discusses its role at the Electrical and Computer...
The Academic Pathways of People Learning Engineering Survey (APPLES) was deployed for a second time in Spring 2008 to undergraduate engineering students at 21 American universities. The goal of APPLES was to corroborate and extend findings from the academic pathways study and the first deployment of APPLES (Spring 2007) on factors that correlate with persistence in engineering on a national scale...
