TL;DR: This paper proposes a protocol that provides QoS service, by means of timing guarantees, to the supported applications in ad hoc wireless networks.
Abstract: A delay-bounded service in wireless ad hoc networks is challenging, as ad hoc networks do not provide any type of guarantees. Several protocols have been proposed to support applications without timing requirements in ad hoc networks, but the increasing demand of QoS applications, in ad hoc wireless environments, requires delay-bound service. The contribution of this paper is to propose a protocol that provides QoS service, by means of timing guarantees, to the supported applications in ad hoc wireless networks.

TL;DR: This work defines a description language to express multimedia contents in a textual way, with higher representation efficiency than existing languages, as well as addressing security issues that arise from the use of an open format.
Abstract: The digital music revolution has improved the availability of music and made it easier to enjoy. The shift from hard support, such as audio CDs, to software leaves some unsatisfied by the loss of additional media contents, such as images, lyrics, and CD cover. We propose to fill the gap by enriching e-music with multimedia contents. Our proposal focuses specifically on MP3 as a widely distributed open format. The challenge we meet in enriching MP3 lies in maintaining audio compatibility and avoiding file size explosion. To this end, we define a description language to express multimedia contents in a textual way, with higher representation efficiency than existing languages. We also address security issues that arise from the use of an open format. Effectiveness is shown with an MP3 player capable of rendering multimedia contents.

TL;DR: A novel, automatic, simple and low-cost mechanism that does not require human transcriptions or special dedicated software to align captions is proposed and can be helpful to expand video content accessibility.
Abstract: With a growing number of online videos, many producers feel the need to use video captions in order to expand content accessibility and face two main issues: production and alignment of the textual transcript. Both activities are expensive either for the high labor of human resources or for the employment of dedicated software. In this paper, we focus on caption alignment and we propose a novel, automatic, simple and low-cost mechanism that does not require human transcriptions or special dedicated software to align captions. Our mechanism uses a unique audio markup and intelligently introduces copies of it into the audio stream before giving it to an off-the-shelf automatic speech recognition (ASR) application; then it transforms the plain transcript produced by the ASR application into a timecoded transcript, which allows video players to know when to display every single caption while playing out the video. The experimental study evaluation shows that our proposal is effective in producing timecoded transcripts and therefore it can be helpful to expand video content accessibility.

TL;DR: The obtained results show that anti vaccination groups use a language that is difficult to refute, whereas the analysis of pro vaccination groups reveals much more anxiety and specificity, which might help health professionals to stop the negative vaccination coverage trend.
Abstract: Social media have brought undoubted benefits to our life, but when people use them to make health decisions, a threat for the whole society might arise. For instance, different studies showed a correlation between the increasing usage of social media to discuss about vaccination and the decreasing vaccination coverage, which leads to outbreaks of preventable diseases. The goal of this paper is to understand specific features of the language used to talk about vaccinations on social media platforms. First, we define four different linguistic and psychological categories of messages: (i) affective (e.g., anger and anxiety), (ii) social (e.g., family and entity), (iii) medical (e.g., disease and vaccine-preventable diseases), and (iv) biological (e.g., body and health-related language). Then, we develop a Python-based tool able to map more than 200.000 messages found on Italian Facebook groups that converse about vaccinations into the defined categories. The obtained results show that anti vaccination groups use a language that is difficult to refute (e.g., not anxious, not focused on specific health issues or on specific diseases), whereas the analysis of pro vaccination groups reveals much more anxiety and specificity (e.g., family cases, specific diseases or vaccines). These results might help health professionals to stop the negative vaccination coverage trend, as they allow them to produce social media contents with linguistic and psychological features suitable to contrast partial/misleading information.

TL;DR: This paper proposes a new real-time protocol, called RT-Ring, able to support transmissions of both real- time and generic traffic over a ring network, and provides both network guarantees and high network resource utilization, while ensuring the compatibility with the emerging differentiated service architectures.
Abstract: Distributed applications with quality of service (QoS) requirements are more and more used in several areas (e.g., automated factory networks, embedded systems, conferencing systems). These applications produce a type of traffic with hard timing requirements, i.e., transmissions must be completed within specified deadlines. To handle these transmissions, the communication system must use real-time protocols to provide a communication service that is able to satisfy the QoS requirements of the distributed applications. In this paper, the authors propose a new real-time protocol, called RT-Ring, able to support transmissions of both real-time and generic traffic over a ring network. RT-Ring provides both network guarantees and high network resource utilization, while ensuring the compatibility with the emerging differentiated service architectures. Network guarantees are fully proved and high network utilization is highlighted by a comparative study with the FDDI protocol. This comparison shows that RT-Ring network capacities are greater than the corresponding FDDI capacities. In fact, by assuming the FDDI frames with a length equal to the RT-Ring slot size and by using the same traffic load the authors show that the capacities of FDDI are equal to the lower bound capacities of RT-Ring.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality. Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: This survey describes the current state-of-the-art in the development of automated visual surveillance systems to provide researchers in the field with a summary of progress achieved to date and to identify areas where further research is needed.
Abstract: This survey describes the current state-of-the-art in the development of automated visual surveillance systems so as to provide researchers in the field with a summary of progress achieved to date and to identify areas where further research is needed. The ability to recognise objects and humans, to describe their actions and interactions from information acquired by sensors is essential for automated visual surveillance. The increasing need for intelligent visual surveillance in commercial, law enforcement and military applications makes automated visual surveillance systems one of the main current application domains in computer vision. The emphasis of this review is on discussion of the creation of intelligent distributed automated surveillance systems. The survey concludes with a discussion of possible future directions.
