Key node selection based on a genetic algorithm for fast patching in social networks

Summary Online social network users provide considerable amounts of personal information and share this information with friends without space‐time limitations. The tight connectivity among users of social networks causes the rapid spreading of information. Given the popularity of social networking sites, there is a high probability of attacks. Worms target popular users with interesting information to infect them, as their higher reputations have more power in social networks. Therefore, timely patch propagation schemes must be able to inhibit the activity of worms. To improve the patch propagation speed, it is important to select key nodes that are the starting points of the patch process. In this paper, we proposed a key node selection scheme based on a genetic algorithm to find the most significant contribution nodes of patch propagation. We modeled the usage patterns of an online social network user and simulated the proposed scheme with data from this user. Simulation results show that the proposed scheme propagates patches more rapidly than existing schemes.
IFLA Statement on Net Neutrality and Zero-rating: At the backstage of the problem

The article analyzes the IFLA Statement on Network Neutrality and Zero-rating adopted on August 15, 2016 at the meeting of the World Library and Information Congress of the 82nd IFLA Conference inColumbus,USA, its importance for the international library community, as well as the socio-economic and cultural context, which was due to its adoption. Speaking in defense of network neutrality and against the practice of the zero-rating, IFLA designated a zone of latent for that period conflict of commercial interests of Internet providers and rules of equal access of the user to all types of content without speed and additional fee. Conflict this year later, in 2017, became public in the period of active struggle against the abolition of the principle of network neutrality in theUnited States. The market rate of traffic, the green light of which was opened as a result of the cancellation of network neutrality in theUnited Stateson December 14, 2017 by the Federal Communications Commission, is particularly sensitive for libraries with limited funding, unable to pay for high-speed Internet. In addition to paid access to broadband Internet, the obvious danger for libraries is the practice of zero rating, providing free and unlimited traffic in the framework of popular social networks or package tariff plans from large corporations, which leads to the monopolization of the information market by the largest IT corporations and the further marginalization of libraries. The displacement of cultural and educational institutions as a non-profitable sector on the roadside negatively affects libraries as providers of access and as creators of Internet content; strikes both on the acquisition of funds, and on the maintenance of readers of high-quality noncommercial information. As natural opponents of progressing monetization, the Library's networks favor the interpretation of the Internet as a public service, a publicly available public resource with a transparent and stable tariff, legislatively protected from attempts by providers to receive super-profits.
Assessing the Preservation of Derivative Relationships in Mappings from FRBR to BIBFRAME

Support of the exploration user task demands the explicit representation of bibliographic families and of content relationships. Seamless navigation through differently modelled bibliographic datasets presumes the existence of mappings. Semantic interoperability through mappings will be evaluated using a testbed. This paper starts with the fine-tuning of a testbed for mappings from FRBR to BIBFRAME. Two Gold Standards datasets have been created along with a mechanism for the mapping of core entities and the derivation relationship from FRBR to BIBFRAME. This first attempt has revealed that derivations expressed at the FRBR Expression level are mapped to BIBFRAME more adequately than those expressed at the FRBR Work level.
Navigating OWL 2 Ontologies Through Graph Projection

Ontologies are powerful, yet often complex, assets for representing, exchanging, and reasoning over data. Particularly, OWL 2 ontologies have been key for constructing semantic knowledge graphs. Ability to navigate ontologies is essential for supporting various knowledge engineering tasks such as querying and domain exploration. To this end, in this short paper, we describe an approach for projecting the non-hierarchical topology of an OWL 2 ontology into a graph. The approach has been implemented in two tools, one for visual query formulation and one for faceted search, and evaluated under different use cases.
Environments Diagnosis by Means of Computer Vision System of Autonomous Flying Robots

In this chapter, the authors present an approach to the extrinsic environs diagnostics based on using visual information collected by autonomous robots. The possibility of utilizing a computer vision for the purpose of rational control implementation in the condition of the full or partial uncertainty is investigated. In the study, the combined hardware and software computer vision tools were verified. The models, algorithms, and codes for solving the local tasks of obstacle identification and mutual location kinematic parameters estimation have been developed. A series of computational and in-kind experiments that illustrate a practical possibility of implementing the navigational environment diagnosis is carried out with the aim to select a rational flight path.
Multi-partite entanglement in Davies environment

We analyse dynamics of genuinely multi-partite entanglement of N-qubit states initially prepared in the form of so called X-matrices with one qubit coupled to a Davies-type environment. We develop an analytic formula for genuinely multi-partite concurrence of the investigated states as a function of time and analyze its time evolution with an emphasis on the qualitative difference between systems affected by a pure decoherence only and those which do dissipate energy at finite temperature.
Strategies for the teaching-learning experiences in the engineering dynamics course based on the information and communication technologies

Technological developments in almost all sectors of industry and/or society has permitted to implement them even in universities by means of it is called ICT. This commits the universities to modify their educational approaches towards those that allow professionals be trained according to what the globalized industry demands today. In addition, it has been taking advantage of the virtual platforms in support of the teaching/learning experiences for the undergraduate courses that facilitate some activities like either the implementation of software of engineering or the student participation in forums or the revision of some concepts which can be impossible to understand in the traditional way of teaching. The Universidad Industrial de Santander (UIS) in Bucaramanga, Colombia, is looking for building a future with a continuous improvement, has undertaken several institutional projects in search of being at the forefront of the pedagogical and social requirements; This study sought to impact the current methods of teaching, and thus achieve a work in synergy with all the university that allows to show the UIS as an entity that continues to promote integrity and quality professionals. This project was divided into two stages. The first included the selection and thematic organization of the course, creating the virtual classroom in the Moodle platform and developing activities and tools that will be used there. The second phase was implementation. Always prioritizing skills training that improves quality and allows the future professional to adapt and meet the requirements demanded by the industry today.
The Review of Task Scheduling in Cloud Computing

Cloud computing is based on the calculation model of the internet platform, which model can access through the network to share the storage resources of network, service, storage and to reduce the workload of people. In order to meet the requirements of quality services, economic principles, and other requirements to allocate a large number of data tasks reasonably, many experts and scholars regard task scheduling strategies as an important research object for cloud computing. In the process of task scheduling, many issues are considered, such as cost, time, resource utilization, etc. In order to reasonably schedule and manage virtual machines, a task scheduling model was proposed. This paper mainly discusses the problems encountered in the process of resource management, and discusses the existing scheduling strategies and the problems in the research. In order to balance the influence of various factors on the scheduling algorithm, a task scheduling multi-objective task optimization was proposed.
The Value of Information and the Internet of Things

We investigate a theory for the Value of Information (VoI) with respect to the Internet of Things (IoT) and IoT's intrinsic artificial intelligence. In an environment of ubiquitous computing and information, information's value takes on a new dimension. Moreover, when the system in which such a volume of information exists is itself intelligent, the ability to elicit value, with consideration of context, will be more complicated. Classical economic theory describes the relationship between value and volume which, though moderated by demand, is highly correlated. In an environment where information is plentiful, such as the IoT, the intrinsic intelligence in the system will be a dominant moderator of demand (e.g., self-adapting, self-operating, and self-protecting; controlling access). We examine Howard's (1966) VoI theory from this perspective and illustrate mathematically that Howard's focus on maximizing value obfuscates another important dimension, the guarantee of minimal value.
An application of the bicycle lane on the complete street concept in efforts reducing global warming impact

The incomplete roads, designed only for cars, with limited transportation options make pedestrians, cyclists, and other transport users feel uncomfortable and safe and risk dangerous. The bicycle as a more environmentally friendly means of transportation which is an alternative mode of transportation that can replace motor vehicles to reduce the impact of global warming. Facilities for bicycle users provide a sense of security and comfort to the various users and is considered an important part of the complete street where a community of 100,000 people replacing their cars by bicycle a month will reduce 3.764 tons of carbon dioxide gas (C02) per year. Yos Sudarso Road in Mamuju City is a road segment with activities in various zones, the intensity of activities that occur on the road is very high at certain hours, due to the different activities of the diversity of building functions. Road conditions that do not provide facilities for bicycle users require assessment of the needs of bicycle lane and analyze how the design of the concept of bike lane on the road segment is based on the complete street concept. The type of research used is non-experimental descriptive with the qualitative and quantitative approach, using a survey method in the form of direct observation at research sites, interviews and questionnaires. The condition of the road lane is not yet based on the complete street concept because there is no bicycle lane available as one of the complete street elements so it does not provide a sense of security and comfort for bicycle users. The need for bicycle lanes based on the responses of respondents is the need to provide bike lanes, on segment 1 with bike lane type, on segment 2 and segment 3 with bike lane type, for provision of bicycle lane based on bicycle volume and volume the traffic needs of the bike lane on Yos Sudarso road segment is not yet necessary to be provided. The recommended implementation of bicycle lane based on the concept of Complete Street is a bike lane (width of 1.5 meters for a one-way lane with elevated surfaces that can still be passed by motor vehicles in an emergency condition. A safe and comfortable bike lane improves people's enthusiasm using bicycles as a mode of transportation that can help reduce carbon dioxide (C02) gas and improve clean air quality.
Engineering Classes as a Tool of Professional Navigation

The article emphasizes the importance and relevance of engineering education in the face of challenges of the modern information society, development of new technologies and knowledgeintensive industries. Attention is paid to the low level of demand for engineering professions among potential entrants, as well as to the issue of developing competencies needed for a modern engineer, taking into account the requirements of the labour market. The article describes the experience of I.N. Ulianov Chuvash State University on organizing career-guidance work with pupils of educational in-stitutions, including implementation of projects aimed at popularization of engineering education. One of such significant for the region projects is “Engineering classes”, in which senior classes schoolchildren of four leading partner-schools of the University take part. The training program includes lessons on mathematics, physics and computer sciences, reinforcing training of future entrants for getting higher engineering-technical education, as well as an elective part on solving applied engineering tasks from the following sections: electronics, robotics, mechatronics, 3D modeling, engineering graphics, and prototyping. A specific feature of the project is a broad engagement of students majoring in technical directions as tutors into the educational process when schoolchildren perform research and design work. Along with higher levels of knowledge in basic subjects for a future engineer, an active participation of schoolchildren in project activities makes it possible to develop communication skills, acquire experience of team work, which is particularly in demand by employers. The article stresses the important role of the largest industrial regional enterprises in implementing the project. These enterprises provide their production sites to explore the organization of production and professional activities of engineers, as well as participate in holding Olympiads and creative contests and provide opportunities for subsequent target training. Thus, the project «Engineering classes» makes it possible to implement the model of continuing education in a single chain «School-University-Enterprise», thereby creating preconditions for the growth of human capacity in regional high-tech enterprises.

Data Literacy and Research Data Management: The Case at ULSIT

In 2017 a team of researchers from the University of Library Studies and Information Technologies (ULSIT) joined an international research group to conduct a scientific survey on Data Literacy and Research Data Management. In the research paper we examine the current state of data literacy, data sharing and reuse perceptions and practices among researchers at ULSIT. The research, which found gaps in understanding of data management best practices, provides recommendations for data literacy training to be provided in the near future. The implementation of the survey was timely, necessary, and useful in light of current amendments to the Act for the Development of the Academic Staff in the Republic of Bulgaria (2018). Analysis of the current levels of awareness and gaps in knowledge among the survey population has resulted in the creation of a document with recommendations for changes to the university’s data management policy that also includes specific improvements for the university’s Quality of Education Management System.
A novel analogue keyboard for embedded applications, based on integer division truncation

Modern micro-controllers are powerful control devices available in a range of packages with a variable number of input/output pins. Smaller microcontrollers, for example the Attiny45, have only six available pins for input/output but relatively powerful performance in terms of processing. However, it is often not possible to exploit the resources of such a microcontroller due to the limited number of pins available. Using an analogue keyboard only one pin of a microcontroller is required. In other analogue keyboards, each character or command corresponds to an analogue value produced on the nodes of a voltage divider composed of several resistors. The principle difference between the system proposed here and previous analogue keyboards is in the algorithm. Because no resistor has zero tolerance, the voltage drop across the voltage divider nodes in a standard analogue keyboard is never precisely as expected. Thus, in order to function correctly, the microcontroller must be programmed for such a system so as to recognise that each analogue value lies between two particular fixed values. In the proposed system, the discretisation is instead entrusted to an approximation from an integer division. Using the same approach, it is also possible to easily convert a standard potentiometer into a discrete switching device. This keyboard is not intended to replace a standard alphanumeric computer keyboard, rather it is an alternative for any case where a cheap, compact micro-controller based device requires control, particularly when a microcontroller has limited input/output pins. Lastly it can be implemented as an analogue rotating selector, and is adaptable because the number of selection steps/keys is set purely as a software parameter.
The pedagogical competences and their importance in virtual physical education

Pedagogical competences have been imposed in relation to the development of face-to-face and virtual education policies in the world. In Colombia, the competency-based curriculum has been used at all levels of the Education System. However, there are shortcomings in the training of teachers in regard to the implementation and execution of different activities that allow the full development of the school and university environment. The research focuses on the pedagogical competences of the teacher of Physical Education at the Education level. It is a journey that took place, taking into account the orientations of qualitative research, under the hermeneutical paradigm and the ethnographic method. Likewise, the observation techniques were used. For the theorization process, the authors' approaches were taken into account, who proposes stages or levels for the development of a research: categorization, structuring, contrasting and theorizing. At the end of the research, ponders were made on the harmonic relationship in Physical Education, where the achievement of the objectives depends on the pedagogical skills assumed by teachers with teamwork, based on values, motor skills, sports, playful and other expressions of the movement seeking the fullness of the spirit in the body-soul relationship. Key words: Pedagogical competences, Face-to-face and virtual Physical Education.
What is Said and What is Understood? The Readability and Language of Child Protection Medical Reports

Key Practitioner Messages Child protection medical reports provide the voice and opinion of a paediatrician, and must be readable by all. Child protection medical reports should include a professional opinion even if the opinion is one of being unsure. Simple measures can improve the readability of reports. A number of descriptive words are used in the opinions of reports. Standardisation of these could be encouraged to reduce misinterpretation. ‘Child protection medical reports provide the voice and opinion of a paediatrician, and must be readable by all’
Techniques for natural-style proofs in elementary analysis

Combining methods from satisfiability checking with methods from symbolic computation promises to solve challenging problems in various areas of theory and application. We look at the basically equivalent problem of proving statements directly in a non-clausal setting, when additional information on the underlying domain is available in form of specific properties and algorithms. We demonstrate on a concrete example several heuristic techniques for the automation of natural-style proving of statements from elementary analysis. The purpose of this work in progress is to generate proofs similar to those produced by humans, by combining automated reasoning methods with techniques from computer algebra. Our techniques include: the S-decomposition method for formulae with alternating quantifiers, quantifier elimination by cylindrical algebraic decomposition, analysis of terms behaviour in zero, bounding the ∈-bounds, rewriting of expressions involving absolute value, algebraic manipulations, and identification of equal terms under unknown functions. These techniques are being implemented in the Theorema system and are able to construct automatically natural-style proofs for numerous examples including: convergence of sequences, limits and continuity of functions, uniform continuity, and other.
Optimal Classifier for Fraud Detection in Telecommunication Industry

Fraud is a major challenge facing telecommunication industry.A huge amount of revenues are lost to these fraudsters who have developed different techniques and strategies to defraud the service providers.For any service provider to remain in the industry, the expected loss from the activities of these fraudsters should be highly minimized if not eliminated completely.But due to the nature of huge data and millions of subscribers involved, it becomes very difficult to detect this group of people.For this purpose, there is a need for optimal classifier and predictive probability model that can capture both the present and past history of the subscribers and classify them accordingly.In this paper, we have developed some predictive models and an optimal classifier.We simulated a sample of eighty (80) subscribers: their number of calls and the duration of the calls and categorized it into four sub-samples with sample size of twenty (20) each.We obtained the prior and posterior probabilities of the groups.We group these posterior probability distributions into two sample multivariate data with two variates each.We develop linear classifier that discriminates between the genuine subscribers and fraudulent subscribers.The optimal classifier ( A B β + ) has a posterior probability of 0.7368, and we classify the subscribers based on this optimal point.This paper focused on domestic subscribers and the parameters of interest were the number of calls per hour and the duration of the calls.
