ISFET drawbacks minimization using a novel electronic compensation

2004

Ion sensitive field effect transistor (ISFET) and membrane field effect transistor (MEMFET) have some drawbacks related to: long-term drift, hysteresis and thermal drift. These factors limit the accuracy of ISFET/MEMFET based measurements systems, specially for continuous or long period measurements. Due to its accuracy, repeatability and easy-to-use features, electronic instrumentation systems are the best tools to design ISFET/MEMFET based measurement systems. A well-designed hardware and a qualified virtual instrumentation software are the key factors to overcome and compensate hysteresis, thermal and long-term drifts ISFET/MEMFET limitations. The paper is dedicated to show an instrument…

Virtual university–a vehicle for development, cooperation and internationalisation in teaching and learning

2005

The paper discusses the approaches of virtual university strategies and developments in Europe. The discussion is partly based on the work done in the Activity 5 in the EU Thematic Network E4 and partly to the experiences gained through the activities of EUNITE virtual university network of six European universities. Based on our experience we see, that e-learning and virtual university approach can be used for renewal of teaching and learning, both on and off campus. Just three years ago, universities seemed mainly to aim only to develop on campus teaching and learning through ICT. Lately, the use of e-learning as a tool for international cooperation and for virtual mobility (Virtual Erasm…

Mobilities in Finland's Information Society Strategies from 1995 to 2010

2012

Abstract The article explores Finland’s national information society strategies and uses the Finnish case as an example to identify the limitation of the so-called ‘methodological nationalism’ and to explicate the advantages of the mobility paradigm. The research material consists of the Finnish national strategies published between 1995 and 2010. The article identifies two trends from the studied strategies; a further intermingling of physical movement of objects and virtual mobility, and a tendency to reduce corporeal mobility. The study also shows that most mobility-related challenges require international cooperation and multinational solutions, although state-centred thinking was preva…

First Trip Abroad: Expectations, Experiences and Stories of Transnational Romanians

2014

Abstract The paper analyzes transnational Romanians’ stories about their first trip abroad. The concept of physical mobility is seen in a broader framework for understanding transnational and cosmopolitan behaviours as well as international migration. In order to distinguish between different types of travelling for the first trip abroad the article is constructed keeping in mind the structural changes and constraints regarding physical mobility for Romanian citizens. During the process of transition from a communist country to the status of EU member, Romanian citizens’ stories about travelling abroad for the first time fundamentally changed. Labour migrants, asylum seekers, business trave…

Cognitive assessment of OCD patients: Neuro VR vs neuropsychological test

2014

This study aimed to evaluate the reliability and validity of the Neuro- Virtual Reality as tool for the neuropsychological assessment in OCD patients. We used the neuropsychological battery and a virtual version of the Multiple Errand Test (V-MET), developed using the NeuroVR software, in order to evaluate the executive functions, the ability to plan ahead on complex problem solving tasks in daily life in 30 obsessive compulsive disorder (OCD) patients and 30 healthy controls. The results showed the presence of difficulties of OCD patients: lower levels of divided attention and higher levels of errors; higher mean rank of inefficiencies, interpretation failures and rule breaks and longer ti…

Virtual Reality Simulator Training of Laparoscopic Cholecystectomies — A Systematic Review

2012

Background and Aims: Simulators are widely used in occupations where practice in authentic environments would involve high human or economic risks. Surgical procedures can be simulated by increasingly complex and expensive techniques. This review gives an update on computer-based virtual reality (VR) simulators in training for laparoscopic cholecystectomies. Materials and Methods: From leading databases (Medline, Cochrane, Embase), randomised or controlled trials and the latest systematic reviews were systematically searched and reviewed. Twelve randomised trials involving simulators were identified and analysed, as well as four controlled studies. Furthermore, seven studies comparing black…

Virtual Reality and Other Realities

2017

Abstract In this chapter, we describe virtual reality and other mixed reality technological tools, highlighting the role they can play in the Clinical and Health Psychology fields: as stimulating, safe and controlled therapeutic contexts for applying psychological treatments; as ecological settings for conducting psychological assessment; and as a realistic laboratory for psychopathology to test research questions that would be very difficult or impossible to address in a traditional laboratory setting. The existing meta-analyses and systematic reviews of their efficacy are presented. The majority of studies have used virtual realities (VRs) as exposure techniques. This is not surprising, c…

Escenarios tecnológicos con dispositivos móviles para la acción educativa. Tendencias y vínculos con la imagen

2021

Presentamos un acercamiento a los escenarios educativos con TIC en la actualidad, en concreto tecnologías portables y modelos pedagógicos de colaboración complementarios a ellas, propios del constructivismo. La capacidad de aprendizaje que estos pueden llegar a suscitar, en cualquier momento y en cualquier lugar, refleja una realidad tangible en nuestra sociedad móvil. Nos referimos a los PLE Entornos Personales de Aprendizaje, BYOD Bring Your Own Device, la Gamificación, Flipped Classroom y la Realidad Aumentada y la Realidad Virtual. Se realiza una revisión de literatura de propuestas pedagógicas destacables, a través de algunos de los principales actores que las abordan en España. En cad…

Redrawing the city and its historical transformations: two examples in Palermo

2015

The representation area is nowaday called upon to face new challenges for new computer technologies that have developed over the last few years. Visual communication and multimedia language experienced a radical change: representation and visualization, thought and image are based on the branch of communication and therefore on the trasmission of knowledge that cannot be separated from the interdisciplinarity. Digital imagery challenges more and more analog imagery, creating a scene that is independent from the constructed reality and sometimes reaching to overlap and merge with it: therefore the representation is no longer just a repetition of the real, but becomes itself an autonomous rea…
