Real Time Information

The world is developing an app that alerts my smartphone when a COVID-19 (COrona VIrus Disease 19) confirmed case comes near me. However, regardless of what will be put to practical use first, the COVID-19 tracking system should satisfy the issues of legalization of location tracking and scalability as a public platform used by the world. Additional problems need solutions related to real-time authentication for information gathering, blind naming and privacy of tracked persons, and quality of service on the Query/Reply procedure. This paper proposes the Software-Defined Networking Controller-centric global public platform to monitor and track information for the COVID-19 relevant people and provide real-time information disclosure services to world-wide Centers for Disease Control and Prevention (CDCs) and regular users. The CDC manages a list of people who needs to be monitored related to the COVID-19 and forcibly installs COVID-19 virtual Internet of Things (vIoT) nodes in the form of applications on their smartphones. In addition to these nodes, the vIoT support nodes also engage as information providers to improve the quality of information services. The design of our platform aims to ensure confidentiality and authentication services giving individually different secret keys. In addition, our platform meets system scalability and reduces Query/Reply latency, where the platform accommodates a large number of world-wide CDCs and persons in control per CDC.

A comparative study was made of the ways in which Australian universities are disseminating information about their courses over the World Wide Web. The study examined the quantity and quality of the information provided, the forms in which information is presented, and means of access to the information. The results of the survey indicated that while the majority of universities are now publishing at least some information over the World Wide Web, both the quantity and quality of information is variable. Implications for further development of institutional course information databases are discussed.

Marine cloud brightening with a sub-micron spray of filtered sea water can exploit the Twomey effect to enhance planetary cooling. Several previous climate model results show that it can also affect precipitation in both directions in different places. Modulating the climate model settings for the concentration of cloud condensation nuclei with separate coded sequences in a number of spray regions round the world and correlating each sequence with the resulting weather patterns in observing stations round the world can give an everywhereto- everywhere transfer function of spray from each region to each observing station. The short life of spray allows the best choices of spray regions and seasons. Spray patterns can be modified tactically to suit real-time weather observations.

The World Wide Web has become an interesting opportunity for companies to deliver services and products at distance. Correspondingly, the quality of Web applications, responsible for the related transactions, has become a crucial factor. It can be improved by properly modeling the application during its design, but if the whole life cycle is considered, the availability of a consistent model of the application is fundamental also during maintenance and testing. In this chapter, the problem of recovering a model of a Web application from the implementation is faced. Algorithms are provided to obtain it even in presence of a highly dynamic structure. Based upon such a model, several static analysis techniques, among which reaching definitions and slicing, are considered, as well as some restructuring techniques. White box testing exploits the model in that the related coverage levels are based on it, while statistical testing assumes that transitions in the model are labeled with the conditional probabilities of being traversed.

AbstractDisability, specifically impaired upper and/or lower limbs, has a direct impact on the patients’ quality of life. Nowadays, motorized wheelchairs supported by a mobility-aided technique have been devised to improve the quality of life of these patients by increasing their independence. This study aims to present a platform to control a motorized wheelchair based on face tilting. A real-time tracking system of face tilting using a webcam and a microcontroller circuit has been designed and implemented. The designed system is dedicated to control the movement directions of the motorized wheelchair. Four commands were adequate to perform the required movements for the motorized wheelchair (forward, right, and left, as well as stopping status). The platform showed an excellent performance regarding controlling the motorized wheelchair using face tilting, and the position of the eyes was shown as the most useful face feature to track face tilting.

AbstractThe quality of cereals is very important for both human and animal nutrition. Fusarium mycotoxins include a great number of compounds. Trichothecenes, zearalenone (ZEN) and fumonisins are the major Fusarium mycotoxins occurring in cereal grains, animal feeds and forages. Conditions that predispose to mycotoxin production by Fusarium species include humidity, temperature, aeration and substrate type. Even if a great number of fungal metabolites have been designated as mycotoxins, a small number are known to have significant animal/human health and economic significance. For this, the world-wide impact of mycotoxins on human and animal health is likely underestimated and the future in this area is to identify additional specific biomarkers and group of biomarkers that can be used to establish the exposition of human and animals to individual mycotoxins.

Research Analysis

Despite the world-wide triumph of democracy, the quest for an optimal politike has not yet reached the “end of history.” It turns out that representative democracies do not necessarily satisfy citizenries. These malaises are regarded as causes for concern and political actors increasingly pin their hopes on participatory innovations as re-legitimizing responses. But do they work? Germany is an especially interesting case for empirical research. Analysis of the variety of participatory innovations utilized at the local level in Germany—often varying considerably among the different Bundesländer—provides preliminary insights. The German case shows overall that participatory innovations have the potential to cure some of the current malaises of representative democracy. Participatory innovations, however, are certainly no fast-track cure. The useful implementation of participatory innovations requires comprehensive consideration, caution, and, (up to now limited) knowledge about possibilities and pitfalls.

AbstractIntroduction:This study aimed to assess the quality of information available on the World Wide Web for patients undergoing thyroidectomy.Methods:The first 50 web-links generated by internet searches using the five most popular search engines and the key word ‘thyroidectomy’ were evaluated using the Lida website validation instrument (assessing accessibility, usability and reliability) and the Flesch Reading Ease Score.Results:We evaluated 103 of a possible 250 websites. Mean scores (ranges) were: Lida accessibility, 48/63 (27–59); Lida usability, 36/54 (21–50); Lida reliability, 21/51 (4–38); and Flesch Reading Ease, 43.9 (2.6–77.6).Conclusion:The quality of internet health information regarding thyroidectomy is variable. High ranking and popularity are not good indicators of website quality. Overall, none of the websites assessed achieved high Lida scores. In order to prevent the dissemination of inaccurate or commercially motivated information, we recommend independent labelling of medical information available on the World Wide Web.

Local Community Detection

In complex network analysis, the local community detection problem is getting more and more attention. Because of the difficulty to get complete information of the network, such as the World Wide Web, the local community detection has been proposed by researcher. That is, we can detect a community from a certain source vertex with limited knowledge of an entire graph. The previous methods of local community detection now are more or less inadequate in some places. In this paper, we have proposed a new local modularity metric [Formula: see text] and based on it, a two-phase algorithm is proposed. The method we have taken is a greedy addition algorithm which means adding vertices into the community until [Formula: see text] does not increase. Compared with the previous methods, when our method is calculating the modularity metric, the range of vertices what we considered may affect the quality of the community detection wider. The results of experiments show that whether in computer-generated random graph or in the real networks, our method can effectively solve the problem of the local community detection.
