Remote Access with SSH

In the frame of the E.U. Leonardo da Vinci project it was accomplished the research and development of several solutions for the distance (and mobile) access to remote reconfigurable laboratory work-benches for e-Learning within electrical engineering education. The authors implemented session-based step-by-step- / auto-mated- (synchronous or asynchronous) test & measurement sequences with remote access - fixed (to rich content) or mobile (with content-to-terminal adaptation), oriented on equipment (with instrument virtualization) or on application with a high degree of visualization (ranging from web-cam monitoring to hyper-schematics). The hardware, netware and software developed (in co-design based on Hewlett-Packard Measurement Subsystems Architecture) is ranging from proprietary solutions to highest degrees of standardized interfacing (mainly IEEE 488.2 GPIB), SCPI instrumentation control, dedicated drivers or Interchange-able Virtual Instruments, IVI, and Measurement Studios software. From the industrial informatics point of view, the present paper is oriented on case studies based on National Instruments LabVIEW suite.

THE opportunity for low cost, high quality training and supervision is an attractive one to most scientists in the cytometry field. Many have had little if any training, no expertise based locally, or may not have the funds to attend regional or international training courses. In addition, rather than general cytometry they may require assistance with a particular application, which could be accomplished in a number of hours through support from an expert. Separately, shared resource scientists, also known as core facility staff, are generally responsible for the performance and upkeep of multiple complex instruments, as well as monitoring, training etc. Some acquisitions or cell sorts may take hours for a single run, and with limited staff the scientist is usually multitasking on an hourly basis. Also, if users of the core facility are having problems and staff is unavailable, valuable samples or time may be lost. There is potential for error at many steps of flow cytometry, including sample preparation, experimental design and fluorochrome selection, instrument set up, compensation, gating, analysis, and interpretation. External/offsite tracking may improve monitoring, and perhaps limit such errors. Also interand intra-instrumentation variations can lead to different results for the same sample. A means of unifying performance, setup, and interpretation is vital, in particular with multicenter collaborations. Peer-review of results and analysis, as well as hierarchical approval systems, provides some solutions, but further stream-lining is clearly beneficial. Remote access technology for cytometry (or remote cytometry) may offer solutions to many such issues and can be performed at very low costs to the institution. There is potential for such systems to facilitate instrumentation monitoring, control equipment in containment areas, speed up vendor service, improve training courses, increase collaborations, and further promote cytometry globally.

Users are increasingly nomadic and want to access their home network from anywhere. Such remote access might also be granted for family members or friends and controlled by the home network owner on a per device basis. This paper describes an overall sound solution for a layer 2 VPN, providing one-click access to the home network. Layer 2 VPN transports all home network protocols, including multicast, UPnP, Windows shares, thus providing full home network experience to remote users. Our solution addresses several practical and technical is- sues such as MAC address filtering and IP collisions. Our solution enables in particular per-device security policy enforcement while sharing the same access credentials with several remote users. We implemented and tested the solution by extending OpenVPN and a home gateway.

Remote access of data using off-the-shelf technologies like internet and GSM/GPRS, is one of the fast growing application areas in industries, customer services, banking, entertainment services etc. This paper presents design and implementation of an auto-responder for educational institute. The design is based on GSM Short Message Service and is used for remote access to data related to examination, results and student’s attendance to be accessed by students or any stack holder, at their own wish. The complete application software, including database management, GSM communication and interactive GUI, is designed in MATLAB. The application provides a good example of the use of Information and Communication Technology (ICT) and illustrates how low cost off-the-shelf technologies like GSM can be meaningfully used for remote data access.

MDSplus remote data access over high latency connections

We present a novel architecture of a communication engine for non-coherent distributed shared memory systems. The shared memory is composed by a set of nodes exporting their memory. Remote memory access is possible by forwarding local load or store transactions to remote nodes. No software layers are involved in a remote access, neither on origin or target side: a user level process can directly access remote locations without any kind of software involvement. We have implemented the architecture as an FPGA-based prototype in order to demonstrate the functionality of the complete system. This prototype also allows real world measurements in order to show the performance potential of this architecture, in particular for fine grain memory accesses like they are typically used for synchronization tasks.

As the extracorporeal membrane oxygenation (ECMO) program at our institution has grown and our staffing model has evolved into a multidisciplinary team, our method of ECMO charting has also evolved, using an electronic medical record (EMR) with electronic checklists, progress notes, and remote access. Using our EPIC charting platform, version 1 of our EMR was implemented in 2015. It has been revised three times, and remote access deemed necessary to properly support our staff and patients. Our current, yet still evolving, remotely accessible, ECMO EMR incorporates hourly charting and protocol-based checklists for procedures such as initiation of support, shift handoffs, circuit checks, and patient transport. Perfusionists are required to fill out thrice daily progress notes, notes for bedside/operating room procedures, and patient transport. We present a format for centers looking to implement a comprehensive EMR for ECMO patients. An expanding ECMO program required a change to our staffing model, and an EMR with electronic checklists and remote access facilitated the transition to a multidisciplinary team. Protocol-based checklists ensure consistency during procedures, transports, and shift changes. The remote access and required progress notes create a safer team approach and keep our perfusionists engaged when specialists are sitting ECMO.

For today's physicists, who work in large geographically distributed collaborations, the data grid promises significantly greater capabilities for analysis of experimental data and production of physics results than is possible with today's ''remote access'' technologies. The goal of letting scientists at their home institutions interact with and analyze data as if they were physically present at the major laboratory that houses their detector and computer center has yet to be accomplished. The Particle Physics Data Grid project (www.ppdg.net) has recently embarked on an effort to ''Interface and Integrate Interactive Data Analysis Tools with the grid and identify Common Components and Services''. The initial activities are to collect known and identify new requirements for grid services and analysis tools from a range of current and future experiments to determine if existing plans for tools and services meet these requirements. Follow-on activities will foster the interaction between grid service developers, analysis tool developers, experiment analysis framework developers and end user physicists, and will identify and carry out specific development/integration work so that interactive analysis tools utilizing grid services actually provide the capabilities that users need. This talk will summarize what we know of requirements for analysis tools and grid services, as well as describe the identified areas where more development work is needed.

Remote access to complex laboratory equipment and the possibility of remotely driving experiments and measurements represent appealing issues of great interest and relevance for research, educational, and industrial purposes. The range of topics potentially involved is very large, including, among others, applications in all fields of engineering, as well as of medicine, biology, and physics [1] Nowadays, the modern learning technologies like e-learning and life-long learning are getting more and more popular. Many current distance learning technologies are passive in that the communication typically flows in one direction, which is only from the instructor to the student, and there is no feedback or delayed feedback in reverse direction [2]. Virtual labs are the element that changes this architecture and allows feedback from the students and increases the interactivity process. In this aspect the role of the virtual labs is growing rapidly. Many universities have their online laboratories. Such are the virtual lab on the course "Computer Organization", in the University of Rousse [3], the virtual laboratory in John Hopkins University[4] and many others. When we talk about e-learning or any other kind of distance education, reasonably arises the question about the laboratory equipment utilization and its remote access. Engineering education without the "touch" to the laboratory equipment is impossible. In one hand, in almost every university lab there is a plenty of hardware equipment that is being used only when traditional classes are being conducted. What we need here is to find a solution to remove the boundaries of the real classroom and to provide remote access and feedback to this equipment. It must be reachable for the students, which are interested on making experiments or playing scenarios whenever they would like and no matter where they are located. The paper is focused on some details of building a remote access system for e-Learning purposes. The system grants remote access for the students to hardware development boards. It combines some features of the virtual e-Learning systems with the benefits of the classical teaching technologies. This is a key factor for the virtualisation process of engineers' training.

Visualization of remote data needs software that is fundamentally designed for distributed processing and high-speed networks. Motivated by and following the requirements of a distributed visualization application, this article describes the design and implementation of a fast and configurable remote data access system called eavivdata. Because wide-area networks may have a high latency, the remote data access system uses an architecture that effectively hides latency. Four remote data access architectures are analyzed and the results show that an architecture that combines bulk and pipeline processing is the best solution for high-throughput remote data access. The resulting system, also supporting high-speed transport protocols and configurable remote operations, is up to 400 times faster than a comparable existing remote data access system.

AimThis single-case feasibility study presents an undergraduate radiotherapy student’s experiences of remote access to University treatment planning software in place of on-site practical learning. With clinical sites increasingly utilising telemedicine there is interest in educational applications of this technology.Materials and methodsThis was an unplanned study with the student initiating remote access; additional tutor support was provided as requested. Subsequent discussion between the tutor and student formed the basis for the presented findings.ResultsA second-year student planned five assessment cases from home, supported by regular on-campus tutorials. The student saved a 2-hour journey per practical and gained additional planning practice time. Unit performance was 10% less than a previous Unit, but student satisfaction with the format was high.FindingsEducational remote access to treatment planning software is logistically feasible, although strict guidelines and formal tutor support is vital. Remote access can alleviate pressure on facilities and improve student time efficiency. Controlled and supported provision of remote access to planning software could enhance on-site practical teaching sessions for more mature independent learners. Further cohort-wide studies could clarify advantages, disadvantages and possible role of remote access for radiotherapy planning education.

New imaging techniques using near-infrared (NIR) fluorescence in combination with remote access thyroidectomy have been studied in endocrine surgery to determine their utility, with the goal of reducing potential complications. Indocyanine green (ICG) imaging is a safe adjunct to remote access thyroid surgery. Nevertheless, experience with ICG is limited, and the caveats surrounding the use of ICG imaging in conventional thyroid surgery exist in remote access surgery as well. This report describes the various remote access techniques and considers the advantages and potential disadvantages of ICG in remote access thyroidectomy.

The economic theory of network externalities and a simple‐game theoretical framework are used to explore the issue of competition among stock exchanges and the possibility of consolidation in the European stock‐exchange industry. The paper shows the existence of equilibria where exchanges may decide, even unilaterally, to achieve full compatibility through implicit mergers and remote access, specialising only in trading or listing services. Thus the consolidation of European exchanges into one may occur with a welfare‐efficient outcome or with a lock‐in to a Pareto‐inferior equilibrium, due to the network externalities and the different starting points of the various exchanges. ‘Implicit mergers’ among exchanges together with remote access are always weakly (in half of the cases, strictly) more efficient than the actual competition. This finding also sheds light on the existence and efficacy, of ATS and rating agencies, which can be viewed respectfully as exchanges specialising in trading and listing services.

Marine robotics is a complex field with a potentially high demanding logistics and high deployment cost. This is a barrier to many research groups. On the other hand, some research groups have substantial equipment and infrastructure that are typically underutilized. The push for sharing infrastructures was recently accentuated due to the COVID-19 pandemic. In particular, remote access experiments became the norm during the lockdown periods. LABUST completed new infrastructure during the COVID-19 pandemic and prepared it for state-of-the-art remote access from anywhere in the globe. This is important both for research and educational purposes. This article describes the infrastructure, equipment, and methods used for implementing the remote access including the calibration procedures. It also reports on real remote access trials for different applications such as Autonomous ships, diver–robot interaction, and Remotely Operated Vehicle (ROV) pilots. These examples include both pool and at-sea remote trials, proving the capabilities of the infrastructure.
