Durchführung von Elektronik-Laborversuchen via Internet von einem entfernten Computer aus

Ausgangspunkt für das Projekt „Remote Electronic Lab“ (REL) waren die Aktivitäten im Bereich Teleleaming am Technikum Kärnten (Carinthia Tech Institute, CTI). Fernstudien gibt es schon seit langer Zeit. Bedingt durch die Entwicklung des Internet ergeben sich aber Möglichkeiten, die eine völlig neue Qualität der Femlehre darstellen. So wie an vielen Hochschulen beschäftigen wir uns in Villach ebenfalls mit der Entwicklung von Telelearning-Modulen. Das ist insbesondere dadurch motiviert, dass es ein berufsbegleitendes Abendstudium „Elektronik“ gibt

Dispositivos móviles para el análisis de circuitos integrados de aplicación específica (CIAE)

The aim of this work is to develop a simultaneous multi user access system—READ (Remote ASCI Design and Test)— that allows users to performtest and measurements remotely via clients running on mobile devices as well as on PCs. The system also facilitates the remote design of circuits with the PAC-Designer®. The system is controlled by LabVIEW® and was implemented using a Data Acquisition Card from National Instruments. Such systems are specially suited for manufacturing process monitoring and control. The performance of the simultaneous access was tested underload with a variable number of users. The server implements a queue that processes user’s commands upon request.El objetivo de este trabajo es desarrollar un sistema multiusuario de acceso simultáneo, CRED (CIAE Remotos, diseño y pruebas) que permite a los usuarios realizar pruebas y mediciones a distancia, a través de clientes que utilizan dispositivos móviles, así como en PC.

80C537 Microcontroller remote lab for e-learning teaching

A remote microcontroller lab based on an 80C537 mock-up is presented. This paper presents a new way to interact with these kinds of systems via the Internet, giving the possibility for complete interaction. The Citrix Application Server is the platform which manages the debugging microcontroller software, and National Instruments LabVIEW 8 is used to develop the applications which allow the interaction between the system and the remote user. By means of LabVIEW web server, full remote interaction has been achieved. Our results suggest a new way to practise in laboratories without being present, yet retaining the feel of an actual laboratory environment.Postprint (published version

A Single-center Comparison Using Exoskeleton Rehabilitation for Cerebrovascular Accidents and Traumatic Brain Injury in a Cohort of Hispanic Patients

Background Traumatic brain injury (TBI) is one of the leading causes of disability in the United States. The EKSO GT Bionics® (EKSO®) is a robotic exoskeleton approved by the Federal Drug Administration (FDA) for rehabilitation following a cerebrovascular accident (CVA or stroke) and recently received approval for use in patients with TBI. The aim of the study was to examine if the use of exoskeleton rehabilitation in patients with TBI will produce beneficial outcomes. Methods This retrospective chart-review reports the use of the (EKSO®) robotic device in the rehabilitation of patients with TBI compared to patients with CVA. We utilized data from a single, private rehabilitation hospital for patients that received post-CVA or post-TBI robotic exoskeleton intervention. All patients that used the exoskeleton were discharged from the hospital between 01/01/2017 to 04/30/2020. Ninety-four percent of patients in the CVA groups and 100% of patients in the TBI group were of Hispanic or Latino ethnicity. Gains in total Functional Independence Measure (FIM), walking and cognition, and length of stay in the rehabilitation facility were measured. Results Patients in the TBI group (n = 11) were significantly younger than the patients in the CVA group (n = 66; p \u3c 0.05). Both groups spent a similar amount of time active, number of steps taken, and the number of sessions in the exoskeleton. Both groups also started with similar admission FIM scores. The FIM gain in the TBI group was similar to that of the CVA group (37.5 and 32.0 respectively). The length of stay between groups was not different either. Conclusions The use of exoskeleton rehabilitation in patients with TBI appear to produce similar outcomes as for patients with CVA, prompting further attention of this intervention for this type of injury.

The furan microsolvation blind challenge for quantum chemical methods: First steps

© 2018 Author(s). Herein we present the results of a blind challenge to quantum chemical methods in the calculation of dimerization preferences in the low temperature gas phase. The target of study was the first step of the microsolvation of furan, 2-methylfuran and 2,5-dimethylfuran with methanol. The dimers were investigated through IR spectroscopy of a supersonic jet expansion. From the measured bands, it was possible to identify a persistent hydrogen bonding OH-O motif in the predominant species. From the presence of another band, which can be attributed to an OH-π interaction, we were able to assert that the energy gap between the two types of dimers should be less than or close to 1 kJ/mol across the series. These values served as a first evaluation ruler for the 12 entries featured in the challenge. A tentative stricter evaluation of the challenge results is also carried out, combining theoretical and experimental results in order to define a smaller error bar. The process was carried out in a double-blind fashion, with both theory and experimental groups unaware of the results on the other side, with the exception of the 2,5-dimethylfuran system which was featured in an earlier publication

From compact to fractal crystalline clusters in concentrated systems of monodisperse hard spheres

We address the crystallization of monodisperse hard spheres in terms of the properties of finite- size crystalline clusters. By means of large scale event-driven Molecular Dynamics simulations, we study systems at different packing fractions {\phi} ranging from weakly supersaturated state points to glassy ones, covering different nucleation regimes. We find that such regimes also result in different properties of the crystalline clusters: compact clusters are formed in the classical-nucleation-theory regime ({\phi} \leq 0.54), while a crossover to fractal, ramified clusters is encountered upon increasing packing fraction ({\phi} \geq 0.56), where nucleation is more spinodal-like. We draw an analogy between macroscopic crystallization of our clusters and percolation of attractive systems to provide ideas on how the packing fraction influences the final structure of the macroscopic crystals. In our previous work (Phys. Rev. Lett., 106, 215701, 2011), we have demonstrated how crystallization from a glass (at {\phi} > 0.58) happens via a gradual (many-step) mechanism: in this paper we show how the mechanism of gradual growth seems to hold also in super-saturated systems just above freezing showing that static properties of clusters are not much affected by dynamics.Comment: Soft Matter, 201

Chemical Mechanisms and their Applications in the Goddard Earth Observing System (GEOS) Earth System Model

NASA's Goddard Earth Observing System (GEOS) Earth System Model (ESM) is a modular, general circulation model (GCM) and data assimilation system (DAS) that is used to simulate and study the coupled dynamics, physics, chemistry, and biology of our planet. GEOS is developed by the Global Modeling and Assimilation Office (GMAO) at NASA Goddard Space Flight Center. It generates near-real-time analyzed data products, reanalyses, and weather and seasonal forecasts to support research targeted to understanding interactions among Earth-System processes. For chemistry, our efforts are focused on ozone and its influence on the state of the atmosphere and oceans, and on trace-gas data assimilation and global forecasting at mesoscale discretization. Several chemistry and aerosol modules are coupled to the GCM, which enables GEOS to address topics pertinent to NASA's Earth Science Mission. This manuscript describes the atmospheric chemistry components of GEOS and provides an overview of its Earth System Modeling Framework (ESMF)-based software infrastructure, which promotes a rich spectrum of feedbacks that influence circulation and climate, and impact human and ecosystem health. We detail how GEOS allows model users to select chemical mechanisms and emission scenarios at run time, establish the extent to which the aerosol and chemical components communicate, and decide whether either or both influence the radiative transfer calculations. A variety of resolutions facilitates research on spatial and temporal scales relevant to problems ranging from hourly changes in air quality to trace gas trends in a changing climate. Samples of recent GEOS chemistry applications are provided
