The Cost

Remote laboratories on mobile phones have been around for a few years now. This has greatly improved accessibility of these remote labs to students who cannot afford computers but have mobile phones. When money is a factor however (as is often the case with those who can’t afford a computer), the cost of use of these remote laboratories should be minimized. This work addressed this issue of minimizing the cost of use of the remote lab by making use of data compression for data sent between the user and remote lab.

Lab work and exercises are an essential part of Electronic Engineering Education as it improves understanding of the theoretical concepts. Remote Labs like VISIR (Virtual Instrument Systems in Reality) can supplement the learning process but are limited to a small set of components. Therefore, experiments with VISIR should be combined with prepared and fixed circuits.<br />This work presents an approach, where in the first step new exercises are de-veloped with the NI ELVIS platform, and later implemented with the much more cost-effective NI myDAQ platform. In general, the entire system is very inexpen-sive and scaleable, since a single PC can act as a host for a wide number of exer-cise boards, each of which is connected via a myDAQ.

<p class="0abstractCxSpFirst"><span lang="EN-US">Remote laboratories are important in education because they provide access to equipment that some institutions cannot afford to purchase or maintain, reduce the need for dedicated physical space for equipment and personnel to staff laboratories. But more than just fill the absence of real physical laboratories; remote laboratories can improve the users experience through the use of adaptive and specific. An important element in supporting shared access is coordinating the scheduling of the laboratory usage. Optimized scheduling can significantly decrease access waiting times and improve the utilization level of remote laboratories resources, with associated reductions in per-use costs.</span></p><p class="0abstractCxSpMiddle"><span lang="EN-US">The user management systems that exist so far are limited, and not compatible with all remote lab interface development software.

Archive aerial photos represent a valuable heritage to provide information about land content and topography in the past years. Today, the availability of low-cost and open-source solutions for photogrammetric processing of close-range and drone images offers the chance to provide outputs such as DEM’s and orthoimages in easy way. This paper is aimed at demonstrating somehow and to which level of accuracy digitized archive aerial photos may be used within a such kind of low-cost software (Agisoft Photoscan Professional<sup>®</sup>) to generate photogrammetric outputs. Different steps of the photogrammetric processing workflow are presented and discussed. The main conclusion is that this procedure may come to provide some final products, which however do not feature the high accuracy and resolution that may be obtained using high-end photogrammetric software packages specifically designed for aerial survey projects. In the last part a case study is presented about the use of four-epoch archive of aerial images to analyze the area where a tunnel has to be excavated.

Internet-enabled technologies for robotics education are gaining importance as online platforms promoting skill training.  Understanding the use and design of robotics are now introduced at university undergraduate levels, but in developing economies establishing usable hardware and software platforms face several challenges like cost, equipment etc. Remote labs help providing alternatives to some of the challenges. We developed an online laboratory for bioinspired robotics using a low-cost 6 degree-of-freedom robotic articulator with a neuro-inspired controller. Cerebellum-inspired neural network algorithm approximates forward and inverse kinematics for movement coordination. With over 210000 registered users, the remote lab has been perceived as an interactive online learning tool and a practice platform. Direct feedback from 60 students and 100 university teachers indicated that the remote laboratory motivated self-organized learning and was useful as teaching material to aid robotics skill education.

<p class="0abstract">The physical training education systems of the faculties of science focus on practical manipulations. Remote Labs are a recent approach used for educating experimental manipulations by using the performance of information and communication technologies. This article presents a real remote laboratory using low-cost embedded systems addressed to engineering and undergraduate students. The manipulation is based on the electronic control system to change the temperature with a plate-form, which is developed to permit students and teacher access to this manipulation. Our purpose of this study is the development of a control system to improve current educational systems in Moroccan universities by managing practical manipulations for a large number of students, based on a web from anywhere and anytime. Measuring and Monitoring of Temperature changes is a new experience of a remote monitoring system that will be allowed the users to access the experiment thought a specific web site.</p>

Abstract Cold temperature failures are often difficult to resolve, especially those at extreme low levels (&lt; -40°C). Momentary application of chill spray can confirm the failure mode, but is impractical during photoemission microscopy (PEM), laser scanning microscopy (LSM), and multiple point microprobing. This paper will examine relatively low-cost cold temperature systems that can hold samples at steady state extreme low temperatures and describe a case study where a cold temperature stage was combined with LSM soft defect localization (SDL) to rapidly identify the cause of a complex cold temperature failure mechanism.

Flexible Operation

With stringent environmental regulations and a new drive for sustainable manufacturing, there is an unprecedented opportunity to incorporate novel manufacturing techniques. Recent political and pandemic events have shown the vulnerability to supply chains, highlighting the need for localised manufacturing capabilities to better respond flexibly to national demand. In this paper, we have used the spinning mesh disc reactor (SMDR) as a case study to demonstrate the path forward for manufacturing in the post-Covid world. The SMDR uses centrifugal force to allow the spread of thin film across the spinning disc which has a cloth with immobilised catalyst. The modularity of the design combined with the flexibility to perform a range of chemical reactions in a single equipment is an opportunity towards sustainable manufacturing. A global approach to market research allowed us to identify sectors within the chemical industry interested in novel reactor designs. The drivers for implementing change were identified as low capital cost, flexible operation and consistent product quality. Barriers include cost of change (regulatory and capital costs), limited technical awareness, safety concerns and lack of motivation towards change. Finally, applying the key features of a Sustainable Business Model (SBM) to SMDR, we show the strengths and opportunities for SMDR to align with an SBM allowing for a low-cost, sustainable and regenerative system of chemical manufacturing.
