Survey on MAC protocols in Underwater Acoustic Sensor Networks

With the advances in technology, Underwater Acoustic Sensor Networks (UW-ASNs) will make it possible to explore and observe the ocean, which covers two-thirds of the Earth's surface. Unlike terrestrial sensor networks, UW-ASNs use acoustic links to explore natural undersea resources and gather scientific data in collaborative monitoring missions. By using the acoustic wave as a means of communication, UW-ASNs are inherently confronted with long and variable propagation delay and high transmission power consumption. These limitations can be overcome by sharing the limited channel resources in an efficient and reliable manner, which can be done by carefully designing MAC protocols. In this survey, we review the unique aspects of UW-ASNs in detail and existing MAC protocols. Finally, we suggest future directions for research on UW-A MAC protocols.
Molten pool temperature measurement based on multi-sensor data fusion

A measuring method of molten pool temperature which is influenced by various factors is designed based on multi-sensor data fusion. With the time-varying measured object, an adaptive weighted fusion algorithm for searching the minimum standard deviation is proposed here. The corresponding weight is achieved by using sensors measurements through approach of self-adaption. The statistic characteristics of estimated standard deviation are also elaborated in this paper. A comparison is made between real-time processing of adaptive weighted fusion algorithm and traditional mean algorithm. The theoretical analysis and experimental results demonstrate that the method can measure molten pool temperature effectively.
A comparative estimation of plasma creatinine concentration using Jaffe’sreaction and kinetic method in patients with chronic renal failure

Chronic Kidney Disease (CKD) is a clinical syndrome that occurs when there is a gradual decline in renal function over time. Creatinine (Molecular Weight 113 Dalton-MW 113 D) is the cyclic anhydride of creatine that is produced as the final product of decomposition of phosphocreatine. In the present work an attempt has been made to compare between results of plasma creatinine using endpoint Jaffe reaction and kinetic method in patients with chronic renal failure. Results from the present study conclude that kinetic Jaffe reaction is better than endpoint Jaffe reaction.

Computation of pseudospectral abscissa for large-scale nonlinear eigenvalue problems

Author(s): Meerbergen, K; Michiels, W; Van Beeumen, R; Mengi, E | Abstract: © The authors 2017. We present an algorithm to compute the pseudospectral abscissa for a nonlinear eigenvalue problem. The algorithm relies on global under-estimator and over-estimator functions for the eigenvalue and singular value functions involved. These global models follow from eigenvalue perturbation theory. The algorithm has three particular features. First, it converges to the globally rightmost point of the pseudospectrum, and it is immune to nonsmoothness. The global convergence assertion is under the assumption that a global lower bound is available for the second derivative of a singular value function depending on one parameter. It may not be easy to deduce such a lower bound analytically, but assigning large negative values works robustly in practice. Second, it is applicable to large-scale problems since the dominant cost per iteration stems from computing the smallest singular value and associated singular vectors, for which efficient iterative solvers can be used. Furthermore, a significant increase in computational efficiency can be obtained by subspace acceleration, that is, by restricting the domains of the linear maps associated with the matrices involved to small but suitable subspaces, and solving the resulting reduced problems. Occasional restarts of these subspaces further enhance the efficiency for large-scale problems. Finally, in contrast to existing iterative approaches based on constructing low-rank perturbations and rightmost eigenvalue computations, the algorithm relies on computing only singular values of complex matrices. Hence, the algorithm does not require solutions of nonlinear eigenvalue problems, thereby further increasing efficiency and reliability. This work is accompanied by a robust implementation of the algorithm that is publicly available.
A Multicast Based Bandwidth Saving Approach for Wireless Live Streaming System

P2P based live streaming applications are growing up rapidly. However, when extending them to WLANs, the bandwidth bottleneck and the high rate of packet loss are usually the major stumbling blocks. To overcome this issue, a new wireless multicast agent mechanism (WiMA) based on the IP multicast scheme for buffer management and scheduling is proposed. First of all, a wireless agent selection method is presented to choose an appropriate agent for WiMA. Then this agent gains media data by interacting with wired neighbor peers as a common P2P node, and transmits these data to other wireless peers in the WLAN by means of multicast pushing and multicast patching. A normal wireless peer requests data according to the strategy of "emergent ones first". Experimental results show that the approach proposed can significantly save bandwidth in WLANs with acceptable start delay and satisfied playing continuity.

Paternidade na adolescência e os fatores de risco e de proteção para a violência na interação pai-criança

This article brings a theoretical review about the adolescent fatherhood and its implications for the father-child interaction, specially the eventual risks for violent behaviors. Some topics relative to adolescent father-child interaction and risk and protective factors for violence in this interaction are discussed. Individual, relational and contextual factors of the father and the child are mentioned in the literature like possible influences in these phenomena. Although some researches found risks of violence in situations involving adolescent fatherhood, there is few studies and evidences that support this fact. The violence is a multidimensional phenomenon,
From Reading Clinic to Reading Community.

This paper discusses the shift from a clinic model to a community model for the practicum experience for literacy education graduate students. The traditional program for the remediation of struggling readers followed a deficit model. Therefore, the reading specialist would pull out the child from regular classroom instruction to isolate a reading problem using standardized assessments and then to remediate the problem with programmed instruction. While the shifts in the understanding of the reading process which occurred in the 1980s and 1990s influenced instruction and assessment and the role of the reading specialist, researchers have found that instruction of struggling readers still tend to be routinized. This has often resulted in what appears to be a lack of personalization, a disregard of experiences, strengths and vulnerabilities that the child brings to the tutoring situation. Therefore, the process of transitioning from a clinic to community model described in this article was made based on the belief that today’s reading clinic component of a literacy specialist program needs to equip its graduate students to face the challenges of the classroom as well as the challenges in transcending their prior understandings and experiences teaching reading.

Why do people use electronic nicotine delivery systems (electronic cigarettes)? A content analysis of Twitter, 2012-2015

The reasons for using electronic nicotine delivery systems (ENDS) are poorly understood and are primarily documented by expensive cross-sectional surveys that use preconceived close-ended response options rather than allowing respondents to use their own words. We passively identify the reasons for using ENDS longitudinally from a content analysis of public postings on Twitter. All English language public tweets including several ENDS terms (e.g., “e-cigarette” or “vape”) were captured from the Twitter data stream during 2012 and 2015. After excluding spam, advertisements, and retweets, posts indicating a rationale for vaping were retained. The specific reasons for vaping were then inferred based on a supervised content analysis using annotators from Amazon’s Mechanical Turk. During 2012 quitting combustibles was the most cited reason for using ENDS with 43% (95%CI 39–48) of all reason-related tweets cited quitting combustibles, e.g., “I couldn’t quit till I tried ecigs,” eclipsing the second most cited reason by more than double. Other frequently cited reasons in 2012 included ENDS’s social image (21%; 95%CI 18–25), use indoors (14%; 95%CI 11–17), flavors (14%; 95%CI 11–17), safety relative to combustibles (9%; 95%CI 7–11), cost (3%; 95%CI 2–5) and favorable odor (2%; 95%CI 1–3). By 2015 the reasons for using ENDS cited on Twitter had shifted. Both quitting combustibles and use indoors significantly declined in mentions to 29% (95%CI 24–33) and 12% (95%CI 9–16), respectively. At the same time, social image increased to 37% (95%CI 32–43) and lack of odor increased to 5% (95%CI 2–5), the former leading all cited reasons in 2015. Our data suggest the reasons people vape are shifting away from cessation and toward social image. The data also show how the ENDS market is responsive to a changing policy landscape. For instance, smoking indoors was less frequently cited in 2015 as indoor smoking restrictions became more common. Because the data and analytic approach are scalable, adoption of our strategies in the field can inform follow-up survey-based surveillance (so the right questions are asked), interventions, and policies for ENDS.
A Personalization and Mobility Aware Service Enabler for a Service Continuity in Heterogeneous Networks

The rapid growth of wired and wireless access technologies integrated with great needs of user nomad supporting services provides strong motivations to focus on the service continuity in a heterogeneous environment. In this paper, we present a personalization and mobility aware service enabler through the session mobility to support service continuity. A four-leveled architecture in the aim of obtaining service session mobility is designed first. User personalization enables us to propose an information structure of user preferences (user profile) and heterogeneous resources around him (usage profiles). Then a user level oriented Virtual Private User Network (VPUN) can be automatically constructed which permits to select the most adequate offers according to the user. By constructing a Virtual Private Network in the Service level (VPSN) thanks to VPUN, we can finally obtain service session mobility to response service continuity. A demonstration will be given out in the end to evaluate the service enabler.

Abstract Author: Marie Kock Title: IN REAL LIFE PA FACEBOOK, Cyborg; A deeper understanding of social phobia and social media Supervisor: Jan Magnusson Assessor: Hakan Jonson The aim of the study is to gain a deeper understanding of the paradox that consist within the phenomena persons with social phobia who participate in social media and to investigate the meaning of social media for people with social phobia who participate in social media. More specifically based on the issues; why do people with social phobia participate in social media? And how do people with social phobia use social media? The study is qualitative and uses the research method, case study. The study's empirical data consists of interviews with people with social phobia who interact on Facebook. The research methodological solution is Internet-research with the technical solutions, qualitative interviews and participant observation. With the help of the theoretical concept, cyborg, we gain a deeper understanding of how the paradoxical phenomenon of social phobia and social media withdrawn once the technology protects the physical body from exposure. This means that Facebook enables participation in social interaction in the virtual room. This is further more something that contributes to an expanded opportunity to experience and define the identity. Key concepts: social phobia, social media, social interaction, cyborg,
The extended flexor carpi radialis approach: a new perspective for the distal radius fracture.

Volar fixation of dorsally unstable distal radius fractures is a new method of treatment that provides the benefits of stable internal fixation without the complications of the dorsal approach. A new, fixed-angle fixation device, the distal volar radius (DVR) plate, (Fig. 1) has been introduced for this purpose. Experience gained by applying this technique to clinically complex cases led us to the realization that more exposure, especially in a dorsal direction, was necessary than that provided by the traditional volar approaches. The need to reduce fractures with significant articular displacement (Fig. 2) and the need to release dorsal callus in inveterate fractures or nascent malunions led us to use an extended form of the flexor carpi radialis (FCR) approach. Volar displaced distal radius fractures are commonly managed with volar buttress plates through the FCR approach. This approach goes deep to the forearm fascia through the FCR tendon sheath and is continuous with the distal part of the Henry approach. The traditional FCR approach provides access to the volar aspect of the distal radius, the volar wrist capsule, and the scaphoid. In comparison with dorsal approaches, which present a high incidence of extensor tendon problems, the FCR approach is relatively free of complications. We extend the FCR approach by releasing the radial septum, by mobilizing the proximal radial fragment, and by using the fracture plane for exposure or what is known as intrafocal technique. Therefore, understanding the anatomy of the radial septum is important. On its proximal aspect, it is a simple fascial wall separating the flexor and extensor compartments of the forearm. At the level of the radial metaphysis, the radial septum is a complex fascial structure that includes the first extensor compartment and the insertion of the brachioradialis. More distally, the radial septum forms the radial insertion of the carpal ligament and ends as the FCR tendon sheath approaches the tuberosity of the scaphoid. The proximal radial fragment has a dependable endosteal blood supply that permits its subperiosteal release and subsequent mobilization. Pronating this fragment out of the way provides wide exposure of the fracture surfaces. This allows the volar reduction and fixation of even the most complex dorsally displaced distal radius fractures. Address correspondence and reprint requests to Dr. Jorge L.

Estimation of intestinal nematode prevalence: influence of parasite mating patterns

Summary Prevalence of infection with intestinal helminths is usually assessed through stool examination. There are limitations in using this technique to measure infection status, since some infected individuals have no patent infection. The relationship between infection assessed by stool examination and actual infection prevalence is investigated for the three major nematode species-Ascaris lumbricoides, Trichuris trichiura and the bookworms-using a model which describes the presence of non-egg producing worm combinations. The analysis demonstrates that stool examination under-estimates the actual infection prevalence, and that the degree of under-estimation is dependent on the level of infection, the nematode species and the parasite sex ratio. These findings have implications for the validity of epidemiological surveys and the evaluation of control programmes.
The Mysteries of Open Source Software: Black and White and Red All Over?

Open Source Software (OSS) has attracted enormous media and research attention since the term was coined in February 1998. The concept itself is founded on the paradoxical premise that software source code-the 'crown jewels' for many proprietary software companies-should be provided freely to anyone who wishes to see it. Given this fundamental initial paradox, it is perhaps hardly surprising that the OSS concept is characterised by contradictions, paradoxes and tensions throughout. In this paper we focus specifically on the following issues in relation to OSS: the cathedral v. bazaar development approach; collectivism v. individualism, the bitter strife within the OSS community itself (OSS v. OSS), and between OSS and the Free Software Foundation (OSS v. FSF); whether OSS represents a paradigm shift in the software industry; whether the software is truly open-the Berkeley Conundrum, as we have termed it here; whether OSS truly is high quality software; and whether OSS is a 'one size fits all,' representing the future model for all software development.
EL CONSUMO DE COCAÍNA DESDE LA PERSPECTIVA PSICOLÓGICA

The problem of cocaine consumption has been gaining importance in Spain in the last few years. Despite the important research efforts made in the field of pharmacology regarding cocaine abuse and dependence, the reference treatment continues to be psychological. This paper offers a synthesis of the most important aspects of cocaine consumption and treatment from a psychological perspective: prevalence data, factors related to the initiation and maintenance of cocaine consumption, assessment of consumption and other associated problems, and psychological treatments with the greatest scientific support. We conclude that psychological treatment is essential in this problem.

Virtual/Mixed/Augmented Reality Laboratory Research for the Study of Augmented Human and Human-Machine Systems

In this work we introduce a new research concept called Augmented Human, and consider how it may benefit from prior research efforts. In essence, the paper describes the long research history of a specific Virtual/Mixed/Augmented Reality (VR/MR/AR) laboratory and reflects how it may well be employed as a premise for Augmented Human research and the design of new human-machine systems. The paper briefly describes how constitutive laboratory research has already been employed for some years in more than a hundred company cases, which have exploited participatory design and human-centered design for the human-machine system development. The paper describes further how the latest cases have moved closer to the human boundary level and thus oriented towards Augmented Human research. This fifth generation VR/MR/AR/AH laboratory has taken the form of an open cave-like environment with a motion platform, 3D sound, haptics, VR/AR Head-mounted displays and physical objects.
Clear and Present Data: Opaque Traffic and its Security Implications for the Future

Opaque traffic, i.e., traffic that is compressed or encrypted, incurs particularly high overhead for deep packet inspection engines and often yields little or no useful information. Our experiments indicate that an astonishing 89% of payload-carrying TCP packets — and 86% of bytes transmitted — are opaque, forcing us to consider the challenges this class of traffic presents for network security, both in the short-term and, as the proportion of opaque traffic continues to rise, for the future. We provide a first step toward addressing some of these challenges by introducing new techniques for accurate real-time winnowing, or filtering, of such traffic based on the intuition that the distribution of byte values found in opaque traffic will differ greatly from that found in transparent traffic. Evaluation on traffic from two campuses reveals that our techniques are able to identify opaque data with 95% accuracy, on average, while examining less than 16 bytes of payload data. We implemented our most promising technique as a preprocessor for the Snort IDS and compared the performance to a stock Snort instance by running both instances live, on identical traffic streams, using a Data Acquisition and Generation (DAG) card deployed within a campus network. Winnowing enabled Snort to handle a peak load of 1.2Gbps, with zero percent packet loss, and process almost one hundred billion packets over 24 hours — a 147% increase over the number processed by the stock Snort instance. This increase in capacity resulted in 33,000 additional alerts which would otherwise have been missed.
