A Hybrid Virtual-Augmented Serious Game to Improve Driving Safety Awareness
2018
The use of 3D virtual content and Augmented Reality (AR) in certain applications allows designing tools and serious games that are more attractive to the potential users. Focusing on the area of learning and education, these technologies can be adapted to the requirements of the application that needs to be developed, to the available devices on which they are expected to run and also to the learning content. However, in most applications only a single interaction paradigm and a single visualization mode is used, restricting the potential benefits of the system. In this paper, we propose a software application designed to improve driving safety awareness and learning for both adults and chi…
Multi-Control Virtual Reality Driving Simulator
2019
Immersive technologies (virtual and augmented reality) started gaining a lot of ground over the past few years initially in the video game industry, followed by simulators and finally integrated into many other classic applications. This paper aims to analyze how users respond to using new controlling devices in a scene designed as a driving simulator (race car track). The landscape and the controls are specifically tailored for interactions within immersive environments. In order to understand the capabilities of the experimental application and evaluate the new controls, several tests were conducted. The results are presented from a user experience perspective, emphasizing qualities, side…
Medium access in WiFi networks: strategies of selfish nodes [Applications Corner]
2009
This article provides a game theoretical analysis of the WiFi MAC protocol to understand the risks or the advantages offered by possible modifications of MAC functionalities implemented at the driver level.
On Unstructured File Sharing Networks
2007
We study the interaction among users of unstructured file sharing applications, who compete for available network resources (link bandwidth or capacity) by opening multiple connections on multiple paths so as to accelerate data transfer. We model this interaction with an unstructured file sharing game. Users are players and their strategies are the numbers of sessions on available paths. We consider a general bandwidth sharing framework proposed by Kelly [1] and Mo and Walrand [2], with TCP as a special case. Furthermore, we incorporate the Tit-for-Tat strategy (adopted by BitTorrent [3] networks) into the unstructured file sharing game to model the competition in which a connection can be …
What Can Research on Technology for Learning in Vocational Educational Training Teach Media Didactics?
2013
Information technology is essential in modern societies; this also applies for educational institutions, as they reflect society’s (schooling) values and intentions. Learners are influenced by the use of technology; even if information technology is not always consciously or intentionally applied, it is literally an actual part of everyday life.
A Bayesian Learning Automata-Based Distributed Channel Selection Scheme for Cognitive Radio Networks
2014
We consider a scenario where multiple Secondary Users SUs operate within a Cognitive Radio Network CRN which involves a set of channels, where each channel is associated with a Primary User PU. We investigate two channel access strategies for SU transmissions. In the first strategy, the SUs will send a packet directly without operating Carrier Sensing Medium Access/Collision Avoidance CSMA/CA whenever a PU is absent in the selected channel. In the second strategy, the SUs implement CSMA/CA to further reduce the probability of collisions among co-channel SUs. For each strategy, the channel selection problem is formulated and demonstrated to be a so-called "Potential" game, and a Bayesian Lea…
Eagle syndrome compared with stylohyoid syndrome: complete ossification of the stylohyoid ligament and joint
2017
A 65-year-old man presented with a history of type 2 diabetes, chronic obstructive pulmonary disease, and non-alcoholic fatty liver. He had had no injuries to, or operations on his neck, but had had right submandibular and retroauricular pain for years. Computed tomography with 3-dimensional reconstruction (Figs. 1 and 2) showed elongation of both styloid processes associated with pseudoarticulation of the hyoid bone on the right side. This confirmed the complete ossification of the stylohyoid ligament, but the patient did not want an operation to resolve it.

From the Blogosphere into Real Politics: The Use of ICT by the Five Star Movement
2014
Research on ICT and the public discourse often focuses on how ICT can be used to increase citizen participation in political decision-making processes. The Italian Five Star Movement (5SM) represents a novel approach to using ICT to include citizens, and a big challenge for the traditional political actors. The 5SM was initiated outside the established political systems, with the use of Internet tools as cornerstones to promote political actions based on the directly expressed will of citizens. In this paper, based on an exploratory case study approach and informed by the introduction of E-Democracy models, we investigate the role of ICT in various phases of the 5SM, from its birth through …
Proximal Tibiofibular Joint Reconstruction With Autogenous Semitendinosus Tendon Graft
2013
Isolated and chronic anterolateral instability of the proximal tibiofibular joint (TFJ) is an uncommon condition, generally linked to an unrecognized or unhealed dislocation of the TFJ. Clinically, abnormal anterior movement of the head of the fibula is detected. In acute injuries conservative management should be preferred, whereas surgical treatment have been advocated in patients with chronic TFJ instability. Authors describe a new surgical reconstruction technique for chronic instability of the proximal TFJ using an autogenous semitendinosus tendon. The graft is passed through fibular and tibia tunnels and fixed with 2 interference screws. The tibial tunnel is reamed from the posterolat…
Blocks of the Trunk and Perineum
1988
Intercostal nerve block was derived from thoracic paravertebral block. Its origin can thus be traced to the beginning of the century (see Sect. VII. B).
