Experience with process migration in the Charlotte distributed operating system is discussed. Charlotte's migration facility is a fairly elaborate addition to the underlying kernel and utility-process base. It separates policy from mechanism. An overview is given of Charlotte, its process migration facility, and issues encountered that have a general application for any such facility. In the discussion of each issue, alternative design approaches adopted by other process migration facilities are presented. This account is intended to help researchers contemplating the addition of a process migration facility as well as those designing other operating system facilities that might need to interact later with added process migration facilities. >

Designing a process migration facility: the Charlotte experience

Twitter, a popular microblogging social networking site, allows individuals to communicate by sending short messages of up to 140 characters. Although it enables people to be in constant contact, its value in educational context is less clear. This paper is the first to examine empirical studies of using Twitter in teaching and learning over 10 years from 2006 to 2015, with the aim of understanding whether its implementation would benefit students or not. We identified a total of 51 eligible publications, and reported the analysis in four major categories: (a) the profile of studies, (b) the specific ways in which Twitter was employed in education, (c) the impacts on interactions, and (d) the impacts on students' learning outcomes. The findings reveal that Twitter was most commonly used for communication and assessment purposes. Although Twitter shows promise in improving interactions among learners and teachers, causality between Twitter use and learning performance remains to be conclusively established. Currently, the most beneficial use of Twitter is probably that of a “push” technology – such as the instructor sending important course information, homework assignments and test deadlines to students, as well as that of a platform for peer interaction. Many challenges still exist in using Twitter for teaching and learning. Based on our review of the literature, we proposed five guidelines that could help promote the educational value of Twitter use. We also identified several limitations of previous studies, and offered suggestions for future work.

Using Twitter for education: Beneficial or simply a waste of time?

Computer-based technology has infiltrated many aspects of life and industry, yet there is little understanding of how it can be used to promote student engagement, a concept receiving strong attention in higher education due to its association with a number of positive academic outcomes. The purpose of this article is to present a critical review of the literature from the past 5 years related to how web-conferencing software, blogs, wikis, social networking sites (Facebook and Twitter), and digital games influence student engagement. We prefaced the findings with a substantive overview of student engagement definitions and indicators, which revealed three types of engagement (behavioral, emotional, and cognitive) that informed how we classified articles. Our findings suggest that digital games provide the most far-reaching influence across different types of student engagement, followed by web-conferencing and Facebook. Findings regarding wikis, blogs, and Twitter are less conclusive and significantly limited in number of studies conducted within the past 5 years. Overall, the findings provide preliminary support that computer-based technology influences student engagement, however, additional research is needed to confirm and build on these findings. We conclude the article by providing a list of recommendations for practice, with the intent of increasing understanding of how computer-based technology may be purposefully implemented to achieve the greatest gains in student engagement.

Computer-based technology and student engagement: a critical review of the literature

Resistive flex sensors can be used to measure bending or flexing with relatively little effort and a
relativelylow budget. Their lightness, compactness, robustness, measurement effectiveness and
low power consumption make these sensors useful for manifold applications in diverse fields.
Here, we provide a comprehensive survey of resistive flex sensors, taking into account their
working principles, manufacturing aspects, electrical characteristics and equivalent models,
useful front-end conditioning circuitry, and physic-bio-chemical aspects. Particular effort is
devoted to reporting on and analyzing several applications of resistive flex sensors, related to the
measurement of body position and motion, and to the implementation of artificial devices. In
relation to the human body, we consider the utilization of resistive flex sensors for the
measurement of physical activity and for the development of interaction/interface devices driven
by human gestures. Concerning artificial devices, we deal with applications related to the
automotive field, robots, orthosis and prosthesis, musical instruments and measuring tools. The
presented literature is collected from different sources, including bibliographic databases,
company press releases, patents, master’s theses and PhD theses.

Resistive flex sensors: a survey

This paper proposes a method for seamless interaction between students and their professor using Twitter, one of the typical social network service (SNS) platforms, in large lectures. During the lecture, the professor poses surprise questions in the form of a quiz on an overhead screen at unexpected moments, and students submit their answers through a smartphone response system using Twitter. Since points are awarded on a first-come–first-served basis to only a limited number of the students who submit correct answers, students are required to concentrate on the lecture if they want to score. The proposed method solves both the problem of decreased concentration arising from frequent use of smartphones for nonlearning purposes in lectures and of inefficient interaction that occurs in large university classrooms. Evaluation through analysis of exam results and a post-course survey confirm that the proposed solution produces better results in terms of both students' academic achievement and their concentration during lectures.

Smartphone Response System Using Twitter to Enable Effective Interaction and Improve Engagement in Large Classrooms

This article describes a reliable gateway for in-vehicle networks. Such networks include local interconnect networks, controller area networks, and FlexRay. There is some latency when transferring a message from one node (source) to another node (destination). A high probability of error exists due to different protocol specifications such as baud-rate, and message frame format. Therefore, deploying a reliable gateway is a challenge to the automotive industry. We propose a reliable gateway based on the OSEK/VDX components for in-vehicle networks. We also examine the gateway system developed, and then we evaluate the performance of our proposed system.

A reliable gateway for in-vehicle networks based on LIN, CAN, and FlexRay

High quality camera images, with good contrast and intensity, are needed to obtain the desired information. Images need to be enhanced when they are dark or bright. The histogram equalization technique, which flattens the density distribution of an image, has been widely used to enhance image contrast due to its effectiveness and simplicity. This technique, however, cannot be used to enhance images that are either too dark or too bright. In addition, it is difficult to perform histogram equalization in real-time using a general-purpose computer. This paper proposes a histogram equalization technique with AGC (Automatic Gain Control) to extend the image enhancement range. It is designed using VHDL (VHSIC Hardware Description Language) to enhance images in real-time. The system is implemented with an FPGA (Field Programmable Gate Array). An image processing system with this FPGA is implemented. The performance of this image processing system is measured.

A Real-Time Histogram Equalization System with Automatic Gain Control Using FPGA

A variety of devices are used for robot control such as personal computers or other human interface devices, haptic devices, and so on. However, sometimes it is not easy to select a device which fits the specific character of varied kinds of robots while at the same time increasing the user's convenience. Under these circumstances, in this study, we have tried to measure user convenience. We tried to understand the characteristics of several devices used to achieve human robot interaction by using each of these devices that could be used with a personal computer: We used a button type device, a joystick, a driving device which consisted of a handle and pedals, and a motion-based human interface device including an acceleration sensor.

This paper presents the unified gateway for an invehicle network using LIN, CAN and FlexRay. The presented gateway uses MPC5567 MCU, including LIN, CAN, and FlexRay communication controllers. In this paper, we propose a reliable gateway algorithm and architecture. In addition, an embedded system is developed for the gateway and the gateway function is implemented. The proposed system is evaluated by experiments under a HEV test bench environment.
