The purpose of the Virtual Lab project is to provide students with online access to a variety of engineering control experiments, located in the laboratory control of several laboratories. Three German universities are currently developing the Virtual Lab as a network of remote access laboratories to establish a pilot testing facility. Assumed students are usually located in an area that is geographically distributed (e.g. at home) and are able to access far from our tests. Virtual Lab is based on the concept of grade learning because some students (e.g. professionals) may be interested in studying even in the most remote areas of the campus which eliminates the need for personal presence. In Virtual Lab they are able to acquire some practice of controlling theory in their own time saving time and travel costs. A Java-based client / server-based approach is proposed. This paper discusses the requirements for remote testing and presents the technical structure and initial results of the project.

Given the growing demand for the use of teams as fundamental building blocks in organizations (Furst, Blackburn, & Rosen, 1999), particularly geographically distributed teams, it is essential to establish a means to ensure their high performance and productivity. The first step to improve our understanding of what makes these teams effective is to identify a series of best practices that should be followed by all those involved in what we call online collaborative teams (OCT): their organizations, leaders and members. OCT are groups of individuals who work on interdependent tasks, share responsibility for outcomes, and join their efforts from different locations. These teams are now being used by many organizations to enhance the productivity of their employees and to reach a diversity of skills and resources. Information technology can support their activities by reducing travel costs, enabling expertise to be captured where it is located, and speeding up team communication and coordination processes. Unfortunately, these distributed teams are not always productive.

The grid has the potential to transform collaborative scientific investigations through the use of closely coupled computational and visualization resources, which may be geographically distributed, in order to harness greater power than is available at a single site. Scientific applications to benefit from the grid include visualization, computational science, environmental modelling and medical imaging. Unfortunately, the diversity, scale and location of the required resources can present a dilemma for the scientific worker because of the complexity of the underlying technology. As the scale of the scientific problem under investigation increases so does the nature of the scientist's interaction with the supporting infrastructure. The increased distribution of people and resources within a grid-based environment can make resource sharing and collaborative interaction a critical factor to their success. Unless the technological barriers affecting user accessibility are reduced, there is a danger that the only scientists to benefit will be those with reasonably high levels of computer literacy. This paper examines a number of important human factors of user interaction with the grid and expresses this in the context of the science undertaken by RealityGrid, a project funded by the UK e-Science programme. Critical user interaction issues will also be highlighted by comparing grid computational steering with supervisory control systems for local and remote access to the scientific environment. Finally, implications for future grid developers will be discussed with a particular emphasis on how to improve the scientists' access to what will be an increasingly important resource.

Abstract Physical laboratory experiments are built to provide students with hands-on opportunities and have long been crucial for engineering training. However, due to the rapid growth in number of enrollments, limited and shared space, undergraduate students have experienced an increasing difficulty gaining valuable hands on experience in the lab. While traditional lab should never be abandoned, adding virtual labs to assist with it could benefit students without the limitation of enrollment capacity or lab availability. In this paper, we discussed a pilot study of developing a virtual fluid mechanics laboratory to supplement existing physical lab exercises. The virtual lab was designed to enrich students’ lab experience, stimulate interests, and bring more individual exercise time. It was developed to contain two components: a virtual lab tour and a virtual reality (VR) simulated pump experiment. The virtual tours served as a pre-lab instruction tool that provided students with an overview of the fluid mechanics lab. The VR pump experiment replicated the physical experience of performing the physical lab. Preliminary feedbacks were positive for both components of the virtual lab. Students considered that the virtual tours were very informative and useful, while that the VR pump lab was intuitive and time-saving. This proved that with realistic lab simulations, the virtual lab had great potential to provide students more flexibility to perform hands-on experiment and to develop technical acumen outside of the physical classroom. Further improvement was discussed to implement in the next stage to create more immersive experience in assistance of the lab instruction.

The study introduces the approach of creating a virtual laboratory for performing laboratory works with remote access. The proposed virtual lab can be used for distance learning and is an extension of the functionality of the previously created virtual workshop. This virtual laboratory with remote access is an alternative to laboratory works performed with real experimental equipment and provides an opportunity to gain skills in operation with measuring microwave equipment without giving classes in educational laboratories. The results of testing virtual lab works with remote access in educational radiophysics laboratories are presented.

Over the past few decades, both small- and medium-sized manufacturers as well as large original equipment manufacturers (OEMs) have been faced with an increasing need for low cost and scalable intelligent manufacturing machines. Capabilities are needed for collecting and processing large volumes of real-time data generated from manufacturing machines and processes as well as for diagnosing the root cause of identified defects, predicting their progression, and forecasting maintenance actions proactively to minimize unexpected machine down times. Although cloud computing enables ubiquitous and instant remote access to scalable information and communication technology (ICT) infrastructures and high volume data storage, it has limitations in latency-sensitive applications such as high performance computing and real-time stream analytics. The emergence of fog computing, Internet of Things (IoT), and cyber-physical systems (CPS) represent radical changes in the way sensing systems, along with ICT infrastructures, collect and analyze large volumes of real-time data streams in geographically distributed environments. Ultimately, such technological approaches enable machines to function as an agent that is capable of intelligent behaviors such as automatic fault and failure detection, self-diagnosis, and preventative maintenance scheduling. The objective of this research is to introduce a fog-enabled architecture that consists of smart sensor networks, communication protocols, parallel machine learning software, and private and public clouds. The fog-enabled architecture will have the potential to enable large-scale, geographically distributed online machine and process monitoring, diagnosis, and prognosis that require low latency and high bandwidth in the context of data-driven cyber-manufacturing systems.

An interactive web-based software on ‘Tensile Testing of Materials’ is developed to help undergraduate students learn more effectively about the objectives, procedure, and methods used in the experiment. The main objective was to better prepare the students in performing their tasks during the physical experiment. The intention of this project is to reap the benefits of both web based training as well as performing the experiments in a practical and interactive sense. Access to the software is given to the students before performing the actual experiment. The software is evaluated to assess its effectiveness. Our initial results verify that the virtual lab could be an effective tool in preparation of the students for the actual experimental tasks in a laboratory environment. In the following paper, the design of the software, important elements of the virtual lab and the evaluation results will be presented.

The number of cochlear implant (CI) users is increasing annually, resulting in an increase in the workload of implant centers in ongoing patient management and evaluation. Remote testing of speech recognition could be time-saving for both the implant centers as well as the patient. This study addresses two methodological challenges we encountered in the development of a remote speech recognition tool for adult CI users. First, we examined whether speech recognition in noise performance differed when the steady-state masking noise was presented throughout the test (i.e. continuous) instead of the standard clinical use for evaluation where the masking noise stops after each stimulus (i.e. discontinuous). A direct coupling between the audio port of a tablet computer to the accessory input of the sound processor with a personal audio cable was used. The setup was calibrated to facilitate presentation of stimuli at a predefined sound level. Finally, differences in frequency response between the audio cable and microphones were investigated.
