Computational Thinking (CT) is an important skill to master in the 21st century. There are several ways that are believed to be able to improve students' CT skills, one of which is the use of block-based programming. Thinking concepts in CT include problem-solving, systems design, and understanding human behavior in terms of basic computer science concepts. Block-based programming is relatively easy to teach because the interface is easier to use, uses natural language, can perform block searches and uses drag and drop interactions. Given the importance of CT skills for students as well as some of the conveniences offered by using block-based programming, it is surprising that this topic has not been explored much. This paper provides a review on 20 papers with a systematic review method, which provides evidence of the influence of block-based programming to computational thinking skills. This systematic review has adopted Chitu Okoli and Kira Schabram framework as the premise for defining and identifying the influence of block-based programming to computational thinking skills. The main findings in this paper is used of block-based programming can affect some of students CT skills through several different delivery methods but there are still some different opinions about the effect on students problem-solving abilities.

The current paper aims to shed light on the effectiveness of using cutting-edge technologies, namely Quizlet, to enhance vocabulary learning. The case study focuses on the first-year Computer Science students (n=121) who were tested on some less frequently used lexis of A2 and B1 levels. Some of them were then taught these vocabulary units as well as some extra ones using the mobile application and the online platform Quizlet in order to be re-tested later, whereas the other half was simply given a list of these new words and expressions to learn on their own. Consequently, there are three stages in this experiment. The choice of this platform for these learners can be accounted for by the fact that Computer Science students are likely to get most of the information in the digital format and thus such an application is bound to enhance their learning experience. The results and conclusions have been made based not only on the second testing of the respondents but also on their own accounts of the degree of their satisfaction with the learning methods offered.

This paper will discuss the applications of Bayes' Rule and Bayesian Classifiers in Cybersecurity. While the most elementary form of Bayes' rule occurs in undergraduate coursework, there are more complicated forms as well. As an extended example, Bayesian spam filtering is explored, and is in many ways the most triumphant accomplishment of Bayesian reasoning in computer science, as nearly everyone with an email address has a spam folder. Bayesian Classifiers have also been responsible significant cybersecurity research results; yet, because they are not part of the standard curriculum, few in the mathematics or information-technology communities have seen the exact definitions, requirements, and proofs that comprise the subject. Moreover, numerous errors have been made by researchers (described in this paper), due to some mathematical misunderstandings dealing with conditional independence, or other badly chosen assumptions. Finally, to provide instructors and researchers with real-world examples, 25 published cybersecurity papers that use Bayesian reasoning are given, with 2-4 sentence summaries of the focus and contributions of each paper.

Peer-to-peer (P2P) computing and technology requirements have exploded in recent years, owing to their wide range of applications in almost every domain. P2P computing and file-sharing methods are now more accessible than ever thanks to advances in computer science and technology. The time it takes for the server to load tends to be lengthened as a result of this. The vast majority of data is held in massive libraries. Networks, on the other hand, cannot operate if several computers transmit large amounts of data over the same cable at the same time. When a computer transfers a large volume of data, other computers are summoned to assist in the processing of the information. The server and network become slow when large chunks of data are withdrawn from the network. The two processes are combined in this paper to reduce the load on the servers. The results are strong since the two algorithms are mixed. The NS2 simulator is used in the implementation. The two methods to be used are the Chunk Delivery with Adaptive Buffer Management Algorithms and the Chunk Delivery with Buffer Management Algorithms. It's based on the number of chunk requests sent to the same number of response providers. The results show that the performance validated the chunk scheduling and buffer management formula's effectiveness. [ABSTRACT FROM AUTHOR]

Currently in Slovakia, there is a strong need to attract more students for their future career in IT or science and technology. The motivation towards these subjects is an important issue at all levels of education and isin the main focus of the national project IT academy. One of its goals at upper secondary level is the introduction of classes with focus on informatics where teaching informatics and science is strengthened a great deal. Except from extra lessons on informatics a new interdisciplinary subject Informatics in science and mathematics is designed. Its main goal is to show interesting problems that can be solved using informatics concepts. For the physics part, we have designed teaching and learning materials on the concept of modeling. Developing models in the physics research cannot be conducted without knowledge of coding in a programming environment. Our main goal is to show students a similar modeling approach on situations that are simple and understandable to them. Students proceed similar way as researchers do, i.e. they get a problem, develop a model, manipulate with it, test the model and improve it to get better correspondence with experimental results. The modeling is conducted in dynamical modeling software where variables are represented by icons that can be a first step to coding in professional programming environment. In the paper we introduce a set of modeling activities designed for the purpose of the presented teaching subject. [ABSTRACT FROM AUTHOR]

Agent-based modelling (ABM) can be used as a computational tool to model human routing behaviour, and offers particular promise when combined with insights from cognitive science. In this paper, we introduce typical errors into the encoding of the agents mental representation of the environment. This method deviates from the classical computer science paradigm of optimality to capture human behaviour more accurately. By incorporating common distance and direction estimation errors, our model produces routes with fewer computational artefacts such as zigzagging (i.e., turning more often than the typical human) and bottlenecks (i.e., routing through one particular node that maximises efficiency).We demonstrate our results in regular and irregular environments and validate our model using a set of real-world footfall data from Westminster, London.

This paper presents an effort to incorporate assessment of manually assessed aspects in an automated code assessment process. Fully automated code assessment has its drawbacks which makes manual assessment of some aspects of student solutions a necessity. In most situations during the assessment of code written by students the most appropriate approach would thus be splitting the process in two phases - automatic plus manual. This might result in two completely distinct procedures for each of the phases. The solution proposed in this paper tries to join these procedures into one uniform process keeping the benefits from each. [ABSTRACT FROM AUTHOR]

In our approach, the machine mind is the applicative dynamic system represented by its algorithmically evolvable internal language. By other words, the mind and the language of mind are synonyms. Coming out from Shaumyan's semiotic theory of languages, we present the representation of language concepts in the machine mind as a result of our experiment, to show non-redundancy of the language of mind. To provide useful restriction for further research, we also introduce the hypothesis of semantic saturation in Computer-Computer communication, which indicates that a set of machines is not self-evolvable. The goal of our research is to increase the abstraction of Human-Computer and Computer-Computer communication. If we want humans and machines comunicate as a parent with the child, using different symbols and media, we must find the language of mind commonly usable by both machines and humans. In our opinion, there exist a kind of calm language of thinking, which we try to propose for machines in this paper. We separate the layers of a machine mind, we present the structure of the evolved mind and we discuss the selected properties. We are concentrating on the representation of symbolized concepts in the mind, that are languages, not just grammars, since they have meaning. [ABSTRACT FROM AUTHOR]

Logic controller specification can be prepared using various techniques. One of them is the wide understandable and user-friendly UML language and its activity diagrams. Using formal methods during the design phase increases the assurance that implemented system meets the project requirements. In the approach we use the model checking technique to formally verify a specification against user-defined behavioral requirements. The properties are usually defined as temporal logic formulas. In the paper we propose to use UML activity diagrams in requirements definition and then to formalize them as temporal logic formulas. As a result, UML activity diagrams can be used both for logic controller specification and for requirements definition, what simplifies the specification and verification process.

‘Machine Consciousness’, which some years ago might have been suppressed as an inappropriate pursuit, has come out of the closet and is now a legitimate area of research concern. This paper briefly surveys the last few years of worldwide research in this area which divides into rule-based and neural approaches and then reviews the work of the author’s laboratory during the last ten years. The paper develops a fresh perspective on this work: it is argued that neural approaches, in this case, digital neural systems, can address phenomenological consciousness. Important clarifications of phenomenology and virtuality which enter this modelling are explained in the early parts of the paper. In neural models, phenomenology is a form of depictive inner representation that has five specific axiomatic features: a sense of self-presence in an external world; a sense of imagination of past experience and fiction; a sense of attention; a capacity for planning; a sense of emotion-based volition that influences planning. It is shown that these five features have separate but integrated support in dynamic neural systems. [ABSTRACT FROM AUTHOR]

This paper presents a hybrid Water Flow-like Algorithm with Tabu Search for solving travelling salesman problem (WFA-TS-TSP).WFA has been proven its outstanding performances in solving TSP meanwhile TS is a conventional algorithm which has been used since decades to solve various combinatorial optimization problem including TSP. Hybridization between WFA with TS provides a better balance of exploration and exploitation criteria which are the key elements in determining the performance of one metaheuristic. TS use two different local search namely, 2opt and 3opt separately. The proposed WFA-TSTSP is tested on 23 sets on the well-known benchmarked symmetric TSP instances. The result shows that the proposed WFA-TSTSP has significant better quality solutions compared to WFA. The result also shows that the WFA-TS-TSP with 3-opt obtained the best quality solution. With the result obtained, it could be concluded that WFA has potential to be further improved by using hybrid technique or using better local search technique. [ABSTRACT FROM AUTHOR]

ARCHERY is an architectural description language for modelling and reasoning about distributed, heterogeneous and dynamically reconfigurable systems in terms of architectural patterns. The language supports the specification of architectures and their reconfiguration. This paper introduces a language extension for precisely describing the structural design decisions that pattern instances must respect in their (re)configurations. The extension is a propositional modal logic with recursion and nominals referencing components, i.e., a hybrid µ-calculus. Its expressiveness allows specifying safety and liveness constraints, as well as paths and cycles over structures. Refinements of classic architectural patterns are specified. [ABSTRACT FROM AUTHOR]

Duplicated code detection has been an active research field for several decades. Although many algorithms have been proposed, only a few researches have focused on the comprehensive presentation of the detected clones. During the evaluation of clone detectors developed by the authors, it was observed that the results of the clone detectors were hard to comprehend. Therefore, in this paper a broadly suitable grouping method with which clone pairs can be easily grouped together to provide a more compact result is presented. [ABSTRACT FROM AUTHOR]

WebOS (Web based operating system) is a new form of Operating Systems. You can use your desktop as a virtual desktop on the web, accessible via a browser, with multiple integrated built-in applications that allow the user to easily manage and organize her data from any location. Desktop on web can be named as WEBtop. This paper starts with a introduction of WebOS and its benefits. For this paper, We have reviewed some most interesting WebOS available nowadays and tried to provide a detailed description of their features. We have identified some parameters as comparison criteria among them. A technical review is given with research design and future goals to design better web based operating systems is a part of this study. Findings of the study conclude this paper.

The article focuses on the different conceptual and philosophical approaches towards the sciences of life operating in the backstage of Early Cybernetics. After a short reconstruction of the main steps characterizing the origins of Cybernetics, from 1940 until 1948, the paper examines the complementary conceptual views between Norbert Wiener and John von Neumann, as a “fuzzy thinking” versus a “logical thinking”, and the marked difference between the “methodological individualism” shared by both of them versus the “methodological collectivism” of most of the numerous scientists of life and society attending the Macy Conferences on Cybernetics. The main thesis sustained here is that these different approaches, quite invisible to the participants, were different, maybe even opposite, but they could provoke clashes, as well as cooperate in a synergic way.

Authenticating users in a continual manner has become extremely critical for a wide range of applications in the domain of pervasive computing and Internet of Things (IoT). In these days, it's also an accepted fact that user authentication based on biometric features is often more efficient than the traditional means of password-based authentication. However, many of the existing biometric techniques like Iris or finger-print recognition are effective only when the person to be authenticated or verified is physically accessible. Thus such technologies are good for applications like Passport Control and fall short of the requirements for IoT applications like an integrated remote-healthcare where different types of users like Doctors, patients, hospitals, insurance companies, other care-givers and even authorized civic-body administrators are to be continually authenticated from remote locations. It is important to ensure that the desired services are accessed only by a legitimate user and no one else. In this paper, we address these issues by proposing a modular solution using key-stroke based biometrics. [ABSTRACT FROM AUTHOR]
