TL;DR: The main characteristics of a Remote Laboratory are presented, the software technologies to implement the client and server sides in a WebLab are analyzed, and a Service Oriented Laboratory Architecture-based approach is suggested for the design of future Remote Laboratories.
Abstract: Remote Laboratories or WebLabs constitute a first-order didactic resource in engineering faculties. However, in many cases, they lack a proper software design, both in the client and server side, which degrades their quality and academic usefulness. This paper presents the main characteristics of a Remote Laboratory, analyzes the software technologies to implement the client and server sides in a WebLab, and correlates these technologies with the characteristics to facilitate the selection of a technology to implement a WebLab. The results obtained suggest the adoption of a Service Oriented Laboratory Architecture-based approach for the design of future Remote Laboratories so that client-agnostic Remote Laboratories and Remote Laboratory composition are enabled. The experience with the real Remote Laboratory, WebLab-Deusto, is also presented.

TL;DR: The VISIR remote laboratory’s positive effect on students’ learning processes indicates that remote laboratories can produce a positive effect in students‘ learning if an appropriate activity is used.
Abstract: Remote laboratories give students the opportunity of experimenting in STEM by using the Internet to control and measure an experimental setting. Remote laboratories are increasingly used in the classroom to complement, or substitute for, hands-on laboratories, so it is important to know its learning value. While many authors approach this question through qualitative analyses, this paper reports a replicated quantitative study that evaluates the teaching performance of one of these resources, the virtual instrument systems in reality (VISIR) remote laboratory. VISIR, described here, is the most popular remote laboratory for basic analog electronics. This paper hypothesizes that use of a remote laboratory has a positive effect on students’ learning process. This report analyzes the effect of the use of VISIR in five different groups of students from two different academic years (2013–2014 and 2014–2015), with three teachers and at two educational levels. The empirical experience focuses on Ohm’s Law. The results obtained are reported using a pretest and post-test design. The tests were carefully designed and analyzed, and their reliability and validity were assessed. The analysis of knowledge test question results shows that the post-test scores are higher that the pretest. The difference is significant according to Wilcoxon test ( ${p} ), and produces a Cohen effect size of 1.0. The VISIR remote laboratory’s positive effect on students’ learning processes indicates that remote laboratories can produce a positive effect in students’ learning if an appropriate activity is used.

TL;DR: This paper describes how the development of experiments is handled in WebLab-Deusto, supporting both managed and unmanaged experiments, and shows the results of integrating remote experiments under this system, with the use case of VISIR, the electronics remote laboratory developed in BTH.
Abstract: During the last decade, efforts have been made in the development and publishing of remote experiments for educational purposes. In order to reduce the duplicity of work and to improve the common requirements that are shared by different remote laboratories, remote experiment management platforms have been developed, such as MIT iLabs, LabShare Sahara or WebLab-Deusto. In this paper, we describe how the development of experiments is handled in WebLab-Deusto, supporting both managed (developed used the APIs provided by WebLab-Deusto) and unmanaged experiments (using Virtual Machines or LabVIEW), and comparing both approaches. It also shows the results of integrating remote experiments under this system, with the use case of VISIR, the electronics remote laboratory developed in BTH.

TL;DR: This technical paper describes an architecture for hybrid labs merging the two approaches, in which virtual and real components interact with each other, and makes use of the Unity technology.
Abstract: Online laboratories have traditionally been split between virtual labs, with simulated components; and remote labs, with real components. The former tend to provide less realism but to be easily scalable and less expensive to maintain, while the latter are fully real but tend to require a higher maintenance effort and be more error-prone. This technical paper describes an architecture for hybrid labs merging the two approaches, in which virtual and real components interact with each other. The goal is to leverage the advantages of each type of lab. The architecture is fully web-based and multiplatform, which is in line with the industry and the remote laboratory community trends. Only recently has this become technically feasible for graphic-intensive laboratories due to previous limitations in browser-based graphical technologies. This architecture relies on the recent HTML5 and WebGL standards to overcome these limitations, and makes use of the Unity technology. To ensure that the proposed architecture is suitable, we set requirements based on the literature, we compare it with other approaches, and we examine its scope, strengths, and weaknesses. Additionally, we illustrate it with a concrete hybrid lab and we evaluate its benefits and potential through educational experiments.

TL;DR: How opening it to public systems (where users do not need to be registered) produces new technical and organizational challenges due to the public availability of labs is described and integrations of systems that were not previously addressed are shown.
Abstract: Remote laboratories are software and hardware tools that allow students to remotely access real equipment located in universities. The integration of remote laboratories in learning tools (learning management systems, content management systems, or personal learning environments) has been achieved to integrate remote laboratories as part of the learning curricula. A cross-institutional initiative called gateway4labs has been created to perform this integration extensible to multiple remote laboratories in multiple learning tools. This contribution focuses on describing this initiative and, in particular, how opening it to public systems (where users do not need to be registered) produces new technical and organizational challenges due to the public availability of labs. In addition, this contribution shows integrations of systems that were not previously addressed in this initiative, such as PhET or ViSH, as well as a new approach for integrating supported laboratories in external specifications such as the smart device one through OpenSocial.

TL;DR: This review paper summarizes the current state-of-the-art IoT in industries systematically and identifies research trends and challenges.
Abstract: Internet of Things (IoT) has provided a promising opportunity to build powerful industrial systems and applications by leveraging the growing ubiquity of radio-frequency identification (RFID), and wireless, mobile, and sensor devices. A wide range of industrial IoT applications have been developed and deployed in recent years. In an effort to understand the development of IoT in industries, this paper reviews the current research of IoT, key enabling technologies, major IoT applications in industries, and identifies research trends and challenges. A main contribution of this review paper is that it summarizes the current state-of-the-art IoT in industries systematically.

TL;DR: Comprehensive and up-to-date, this book includes essential topics that either reflect practical significance or are of theoretical importance and describes numerous important application areas such as image based rendering and digital libraries.
Abstract: From the Publisher: The accessible presentation of this book gives both a general view of the entire computer vision enterprise and also offers sufficient detail to be able to build useful applications. Users learn techniques that have proven to be useful by first-hand experience and a wide range of mathematical methods. A CD-ROM with every copy of the text contains source code for programming practice, color images, and illustrative movies. Comprehensive and up-to-date, this book includes essential topics that either reflect practical significance or are of theoretical importance. Topics are discussed in substantial and increasing depth. Application surveys describe numerous important application areas such as image based rendering and digital libraries. Many important algorithms broken down and illustrated in pseudo code. Appropriate for use by engineers as a comprehensive reference to the computer vision enterprise.
