Inhibition of Eimeria tenella CDK-related kinase 2: From target identification to lead compounds.

2010

Apicomplexan parasites encompass several human- and animal-pathogenic protozoans such as Plasmodium falciparum, Toxoplasma gondii, and Eimeria tenella. E. tenella causes coccidiosis, a disease that afflicts chickens, leading to tremendous economic losses to the global poultry industry. The considerable increase in drug resistance makes it necessary to develop new therapeutic strategies against this parasite. Cyclin-dependent kinases (CDKs) are key molecules in cell-cycle regulation and are therefore prominent target proteins in parasitic diseases. Bioinformatics analysis revealed four potential CDK-like proteins, of which one—E. tenella CDK-related kinase 2 (EtCRK2)—has already been charact…

Using virtual reality and mood-induction procedures to test products with consumers of ceramic tiles

2013

This work describes a Virtual Reality Environment (VRE), through which users are able to view and test ceramic tile products. Users' virtual interfacing with the products generated emotional experiences that allowed them to feel ''engaged'' with the products. Users could choose between different kinds of products and test them out in order to know how they would look in a real-world context. In the VRE several mood-induction Procedures for inducing relaxation were included. The VRE was tested with respect to its ability to induce relaxation and sense of presence in 26 participants. It was also analyzed the level of satisfaction. Measures included the Visual Analogue Scale, the Self-Assessme…

On the potential of NoC virtualization for multicore chips

2008

As the end of Moores-law is on the horizon, power becomes a limiting factor to continuous increases in performance gains for single-core processors. Processor engineers have shifted to the multicore paradigm and many-core processors are a reality. Within the context of these multi-core chips, three key metrics point themselves out as being of major importance, performance, fault-tolerance (including yield), and power consumption. A solution that optimizes all three of these metrics is challenging. As the number of cores increases the importance of the interconnection network-on-chip (NoC) grows as well, and chip designers should aim to optimize these three key metrics in the NoC context as …

ROMOT: A Robotic 3D-Movie Theater Allowing Interaction and Multimodal Experiences

2017

In this paper we introduce ROMOT, a RObotic 3D-MOvie Theater. ROMOT is built with a robotic motion platform, includes multimodal devices and supports audience-film interaction. Differently from other similar systems, ROMOT is highly versatile as it can support different setups, integrated hardware and contents. Regarding to the setups, here we present a first-person movie, a mixed reality environment, a virtual reality interactive environment and an augmented reality mirror-based scene. Regarding to integrated hardware, the system currently integrates a variety of devices and displays that allow audiences to see, hear, smell, touch and feel the movement, all synchronized with the filmic exp…

Real-time acquisition of wideband signals data using non-uniform sampling

2009

Wideband signal acquisition often faces a problem of bulk data recording. It is a critical factor in real-time systems. The paper discusses an approach that deals with this problem incorporating Digital Alias-free Signal Processing and Virtual Instrumentation technologies. Such combination is advantageous for real-time applications and useful in the development of measurement and software defined radio systems. Non-uniform sampling technique allows considerably decrease the data of wideband signals so, that they can be transferred in real-time to a typical PC through high-speed PCI Express communication interface. The experimental prototype system has been developed and obtained results are…

Abstract Patient handover is an important part for information transfer between medical professionals in a clinical setting. Yet, in current medical education, these conversations are only trained sparsely, since they are costly to perform as they take place in offsite courses and are led by experts over several days. Virtual reality (VR)-based training courses could increase the availability of training, by eliminating travel costs and reducing the time-commitment of the teaching experts. This work presents a VR prototype of a multi-user training and examination application for patient handover. To ensure a similar interaction quality to its current real world counterpart, this work used o…

Building and Maintaining the Common Ground in Web-Based Interaction

2002

In this paper, the main purpose is to explore how participants establish and maintain the common ground in the computer-based conferences. Previous studies assume that before the participants can reach the deeper level interaction and learning, they have to gain an adequate level of common ground (Dillenbourg, 1999; Baker et al., 1999; Veerman, 2000). Subjects were 68 pre-service teachers and 7 mentors from three universities who participated in the web-based conferencing course for eight weeks. The results assume that in deeper level discussions it is essential that participants, especially fellow students did give not only the evidence about their own understanding by using written feedba…

Virtual Reality Applications for Higher Educations: A Market Analysis

Discounted Prototyping of Virtual Reality Solutions for Science Education

2017

Science education requires experimental work for learners to achieve the intended learning outcomes, which sometimes involve abstract concepts by nature. Advances in digital technology can help learners to undertake experimental work, which would otherwise be costly, either due to the scarcity of laboratory equipment or safety requirements. However, one of the major concerns resides into how to design usable learning solutions from the users’ perspective. That would require the involvement of users at all stages of design and development process, even if the technology itself could still be in its infancy. It can be very helpful to present the new design concepts to potential users at a ver…

Free networks visible networks

2005

Free network visible network is an active media system that uses the possibilities of the new technologies to create new landscapes in the public space by means of the visualization of the data that flow between digital networks. It changes our perception of the world with the "invisible meanings" that are around us. Mixed reality technology and Internet traffic listening system are adopted in this project in order to visualize, floating in the space, the interchanged information between users of a network. The people are able to experience in a new exciting way about how colorful virtual objects, representing the digital data, are flying around. These virtual objects change their shape, si…
