In this paper, the authors elucidate the characteristics of the computer game Daihinmin, a popular Japanese card game that uses imperfect information. They first propose a method to extract feature values using n-gram statistics and a cluster analysis method that employs feature values. By representing the program card hands as several symbols, and the order of hands as simplified symbol strings, they obtain data that is suitable for feature extraction. The authors then evaluate the effectiveness of the proposed method through computer experiments. In these experiments, they apply their method to ten programs that were used in the UEC Computer Daihinmin Convention. In addition, the authors evaluate the robustness of the proposed method and apply it to recent programs. Finally, they show that their proposed method can successfully cluster Daihinmin programs with high probability.

Automated authorship attribution is actual to identify the author of an anonymous texts, or texts whose authorship is in doubt. It can be used in various applications including author verification, plagiarism detection, computer forensics and others. In this article, the authors analyze an approach based on frequency combination of letters is investigated for solving such a task as classification of documents by authorship. This technique could be used to identify the author of a computer program from a predefined set of possible authors. The effectiveness of this approach is significantly determined by the choice of metric. The research examines and compares four different distance measures between a text of unknown authorship and an authors' profile: L1 measure, Kullback-Leibler divergence, base metric of Common N-gram method (CNG) and a certain variation of dissimilarity measure of CNG method. Comparison outlines cases when some metric outperforms others with a specific parameter combination. Experiments are conducted on different Russian and English corpora.

Full textAbstract:
Abstract Aminoglycosides are still used extensively in the treatment of nosocomial infections with Gram-negative bacteria. However, the treatment is associated with several adverse effects. Aminoglycosides monitoring is therefore essential to prevent toxic accumulations and to reach therapeutic concentrations. A computer program, PHARMONITOR, has been developed to optimize aminoglycosides monitoring, responding to the demands of most clinical daily situations. This program, based on a one-compartment open pharmacokinetics model, is developed for IBM PC-compatible computers, using D-Base III+. It can calculate t1/2, Vd, Cldrug, Cpmax, and the theoretical optimal dose and interval and also evaluates the creatinine clearance. The program has been conceived to allow maximal speed, flexibility, and reliability by the use of (e.g.) a linear least-squares analysis, the possible reference to previous protocols, the extensive use of keywords to classify and recall patients according to their pathologies, the development of messages recommending maximal dose or minimal dosing interval, and increasing the safety of the analysis. We consider the program a valuable tool for adjusting aminoglycoside dosage in individuals.

Full textAbstract:
The Internet of Things (IoT), cloud, and fog computing paradigms provide a powerful large-scale computing infrastructure for a variety of data and computation-intensive applications. These cutting-edge computing infrastructures, however, are nevertheless vulnerable to serious security and privacy risks. One of the most important countermeasures against cybersecurity threats is intrusion detection and prevention systems, which monitor devices, networks, and systems for malicious activity and policy violations. The detection and prevention systems range from antivirus software to hierarchical systems that monitor the traffic of whole backbone networks. At the moment, the primary defensive solutions are based on malware feature extraction. Most known feature extraction algorithms use byte N-gram patterns or binary strings to represent log files or other static information. The information taken from program files is expressed using word embedding (GloVe) and a new feature extraction method proposed in this article. As a result, the relevant vector space model (VSM) will incorporate more information about unknown programs. We utilize convolutional neural network (CNN) to analyze the feature maps represented by word embedding and apply Softmax to fit the probability of a malicious program. Eventually, we consider a program to be malicious if the probability is greater than 0.5; otherwise, it is a benign program. Experimental result shows that our approach achieves a level of accuracy higher than 98%.

Full textAbstract:
The engine control process is usually carried out based on array control algorithms with a fixed mesh size. Modification of control algorithms based on experimental test data requires the use of programs that make it possible to determine the control algorithm param-eters. The article presents the methodology of determining the compression-ignition engine control algorithms. A custom computer pro-gram was presented, which was used to determine the control algorithm parameters. These control algorithms values were determined based on the results of experimental engine tests, and using the presented program. The parameters were introduced into the laboratory compression-ignition engine controller. The experimental tests performed on the engine, whose operation was managed by the pro-grammed laboratory controller, confirmed the usefulness of the proposed methodology for determining input data of control algorithms.

Full textAbstract:
It is difficult for computer to understand the texts in unstructured Chinese language, which becomes an obstacle for further application of artificial intelligence in the power dispatch center. Understanding of the orders from human dispatchers is the premise for the collaboration of machine and human being in power system operation. Towards understanding of dispatching texts, this paper proposes a textual semantic analysis framework with active learning of the semantic structure knowledge. Firstly, the words are vectorized by the Skip-gram models. And the hierarchical clustering algorithm is designed to detect the sentence patterns. Then the knowledge base is set up by converting the sentence structure to their regular expressions. In application, define a proprietary semantic framework to extract important device information and to parse the semantic slot using dependency syntax. Application shows that the Chinese texts describing the operation mode switching process can be understood accurately by the computer program.

<p>Malicious code threatens the safety of computer systems. Researching malicious code design techniques and mastering code behavior patterns are the basic work of network security prevention. With the game of network offense and defense, malicious code shows the characteristics of invisibility, polymorphism, and multi-dismutation. How to correctly and effectively understand malicious code and extract the key malicious features is the main goal of malicious code detection technology. As an important method of program understanding, program slicing is used to analyze the program code by using the idea of “decomposition”, and then extract the code fragments that the analyst is interested in. In recent years, data mining and machine learning techniques have been applied to the field of malicious code detection. The reason why it has become the focus of research is that it can use data mining to dig out meaningful patterns from a large amount of existing code data. Machine learning can It helps to summarize the identification knowledge of known malicious code, so as to conduct similarity search and help find unknown malicious code. The machine learning heuristic malicious code detection method firstly needs to automatically or manually extract the structure, function and behavior characteristics of the malicious code, so we can first slice the malicious code and then perform the detection. Through the improvement of the classic program slicing algorithm, this paper effectively improves the slicing problem between binary code processes. At the same time, it implements a malicious code detection system. The machine code byte sequence variable-length N-gram is used as the feature extraction method to further prove that the efficiency and accuracy of malicious code detection technology based on data mining and machine learning. </p> <p> </p>

Relevance. One of the effective ways to close chronic wounds according to many authors is split-skin grafting. To obtain good results of plastic operations, a constant monitoring of the structure of microbiological associations of chronic wounds and their sensitivity to antimicrobial agents is necessary.
Aim. Analysis of the structure and properties of pathogens of wound infections when performing split-skin grafting and optimizing the choice of drugs for starting empirical antibacterial therapy.
Materials and methods. A retrospective analysis of the results of microbiological studies was conducted in 86 patients who underwent split-skin grafting. For statistical processing of the data obtained, the computer program Statistica 6.0 was used.
Results. Microbial contamination in patients on admission to hospital was (Me [Q1; Q3]) 106 [102; 108] CFU/ml. Unsatisfactory results of split-skin grafting were noted in 15 patients (17%). In this group of patients, strains of non-fermenting gram-negative bacteria - Pseudomonas aeruginosa (in 6 cases) and Acinetobacter baumannii (in 4 cases), which retained sensitivity to carbapenems in 65% of cases, were most often detected.
Conclusions. Non-fermenting gram-negative microorganisms sharply reduce the likelihood of good results of plastic operations. If found in the recipient wound after split-skin grafting signs of an infectious process, it is advisable to use carbapenems.

Full textAbstract:
Modern programming relies on a large number of fundamental APIs, but programmers often take great effort to remember names and the usage of APIs when coding, and repeatedly search the related API documents or Q&A websites (e.g. Stack Overflow). To improve the programming efficiency, we present a Java API suggestion model called APIHelper which learns API sequence pattern via the Long Short-Term Memory (LSTM) network, then provides API suggestion based on the program context. Comparing with statistical methods (e.g. Hidden Markov Model (HMM), N-gram), which require establishing one specific model for each class, we propose Deterministic Negative Sampling (DNS) to make API suggestion for a large number of Java classes by one single end-to-end LSTM. To verify this approach, we make API suggestion for 50,000 Java classes and evaluate it with accuracy and top-K accuracy. The results show that APIHelper outperforms other research works both on accuracy and computation efficiency.

Full textAbstract:
Over the past few years the number of online language teaching materials for non-native speakers of Estonian has increased. However, they focus mainly on vocabulary and pay little attention to pronunciation. In this study we introduce a computerassisted pronunciation training tool, Estoñol, developed to help native speakers of Spanish to train their perception and production of Estonian vowels. The tool’s training program involves seven vowel contrasts, /i-y/, /u-y/, /ɑ-o/, /ɑ-æ/, /e-æ/, /o-ø/, and /o-ɤ/, which have proven to be difficult for native speakers of Spanish. The training activities include theoretical videos and four training modes (exposure, discrimination, pronunciation, and mixed) in every lesson. The tool is integrated into a pre/post-test design experiment with native speakers of Spanish and Estonian to assess the language learners’ perception and production improvement. It is expected that the tool will have a positive effect on the results, as has been shown in previous studies using similar methodology.
Kokkuvõte. Katrin Leppik ja Cristian Tejedor-García: Estoñol, mobiilirakendus hispaania emakeelega eesti keele õppijatele vokaalide häälduse ja taju treenimiseks. Eesti keele õppimiseks on loodud mitmeid e-kursusi ja mobiilirakendusi, kuid need keskenduvad peamiselt sõnavara ja gram matika õpetamisele ning pööravad väga vähe tähelepanu hääldusele. Eesti keele häälduse omandamise lihtsustamiseks töötati välja mobiilirakendus Estoñol, mis on mõeldud hispaania emakeelega eesti keele õppijatele. Varasemad uurimused on näidanud, et hispaania emakeelega eesti keele õppijatele valmistab raskusi vokaalide /ɑ, y, ø, æ, ɤ/ hääldamine. Mobiilirakenduse sisu on jagatud seitsmeks peatükiks, kus on võimalik harjutada vokaalipaaride /i-y/, /u-y/, /ɑ-o/, /ɑ-æ/, /e-æ/, /o-ø/, /o-ɤ/ tajumist ja hääldamist. Iga peatükk algab teoreetilise videoga, millele järgnevad taju- ja hääldusharjutused. Mobiilirakenduse mõju hindamiseks keeleõppija hääldusele ja tajule plaanitakse läbi viia eksperiment.

Full textAbstract:
Aiming at the problems of over reliance on labor and low generalization of traditional emotion analysis methods based on dictionary and machine learning, an emotion analysis model of microblog comment text based on deep learning is proposed. Firstly, text is obtained through microblog crawler program. After data preprocessing, including data cleaning, Chinese word segmentation, removal of stop words, and so on, the Skip-gram model is used for word vector training on a large-scale unmarked corpus, and then the trained word vector is used as the text input of CNN-BiLSTM model, which combines Bidirectional Long-Short Term Memory (BiLSTM) neural network and Convolution Neural Network (CNN). Considering the historical context information and the subsequent context information, BiLSTM can better use the temporal relationship of text to learn sentence semantics. CNN can extract hidden features from the text and combine them. Finally, after Adamax optimization training, the emotion type of microblog comment text is output. The proposed model combines the learning advantages of BiLSTM and CNN. The overall accuracy of text emotion analysis has been greatly improved, with an accuracy of 0.94 and an improvement of 8.51% compared with the single CNN model.

Full textAbstract:
The article focuses on a new way to solve the problem of cutting processing due to the appearance of a wide range of super hard and hard-to-machine structural materials for aircraft, automobile, ship and engine construction, as well as for spacecraft, medi cine (orthopedics, dentistry), nuclear and military equipment. Such materials have an organized regular structure, high strength, super hardness. As a result, there is a problem of defect-free machining of these materials without damaging their balanced structure. The article describes a new approach and formulates innovative principles for creating a new class of mechatronic technological systems for precision machining of parts made of these materials using the example of drilling small diameter deep holes. The core of the mechatronic technological system is a mechatronic parametric stabilizer of the power load on the cutting tool. The mechatronic tech nological system provides a program task, automatic stabilization and maintenance in the tracking mode of the power load on the cutting tool with “disturbance control”. For example, in the technological cycle of drilling small diameter holes, such a system pro tects the drill bits from breakage. An integrated technological system is proposed with the following three levels of control: intelli gent (upper), adaptive (middle) and robust (lower). The basis of the multi-level system is a high-speed robust automatic control sys tem “by the disturbance”. The disturbance is the load torque, which is either automatically stabilized, or tracked when setting a pro gram from a computer, or changes according to the program that sets the mechatronic technological system the functioning (opera tion) algorithm. This algorithm can vary widely with different methods of machining parts by cutting (grinding), including shaping free 3D surfaces according to their digital models. The mechatronic technological system proposed is easily integrated into the cut ting (grinding) system of CNC machines, expanding their capabilities by transferring the standard control program of the CNC to a higher level of the control hierarchy. This allows machining any complex-shaped parts, including “double curvature” parts, namely impellers, turbine blades, rowing screws, etc.

The fungus Monosporascus cannonballus Pollock and Uecker infects melon (Cucumis melo L.) roots and causes root rot/vine decline disease, which has reduced productivity of commercial muskmelon and honeydew cultivars in South Texas. To assess the impact of the fungus on several root traits, two greenhouse experiments were carried out over two seasons. A comparison of inoculated vs. control root systems was carried out with four melon cultivars representing both susceptible (`Magnum 45' and `Caravelle') and tolerant types (`Deltex' and `Doublon'). The sand medium was inoculated with 50–60 colony forming units (CFUs) per gram of the severe Monosporascus strain, TX90-25. After a 30-day growth period, the control and inoculated root systems were carefully cleaned and evaluated. Roots were scanned by a computer and the data were analyzed by the Rhizo Pro 3.8 program. The traits of interest included total root length, average root diameter, number of root tips, number of fine roots (0–0.5 mm), and number of small roots (0.5–1 mm). Significant differences existed between the two tolerant cultivars and the two susceptible ones for four of the traits. Total root length, fine and small root length, and root tip number were greater for `Deltex' than for both susceptible cultivars and greater for `Doublon' than for `Caravelle'. The results suggest that tolerance to this pathogen is closely linked to the integrity of the root structure. The potential for improving root vigor to combat root rot/vine decline merits further investigation.

Full textAbstract:
In this paper we present a new ab initio approach for constructing an unrooted dendrogram using protein clusters, an approach that has the potential for estimating relationships among several thousands of species based on their putative proteomes. We employ an open-source software program called pClust that was developed for use in metagenomic studies. Sequence alignment is performed by pClust using the Smith-Waterman algorithm, which is known to give optimal alignment and, hence, greater accuracy than BLAST-based methods. Protein clusters generated by pClust are used to create protein profiles for each species in the dendrogram, these profiles forming a correlation filter library for use with a new taxon. To augment the dendrogram with a new taxon, a protein profile for the taxon is created using BLASTp, and this new taxon is placed into a position within the dendrogram corresponding to the highest correlation with profiles in the correlation filter library. This work was initiated because of our interest in plasmids, and each step is illustrated using proteomes from Gram-negative bacterial plasmids. Proteomes for 527 plasmids were used to generate the dendrogram, and to demonstrate the utility of the insertion algorithm twelve recently sequenced pAKD plasmids were used to augment the dendrogram.

Full textAbstract:
The following paper considers the immanent principles of digital media evolution. The features of the evolutional route of digital objects are conditioned by glitches, errors and bugs, which appear in media functioning, what in its turn gives birth to the new forms, structures and configurations of digital reality. The glitches are considered not only as a kind of digital mutations, but also as a sign of activity of media. Decisions elaborated from the programs’ failures enlarge the resolution capacity of new technologies. The paper provides an analysis of certain errors and glitches, which engineers, programmers, game designers faced with during their work with digital environment. The theoretical framework includes Henri Bergson’s theory of creative evolution, Gram Harman’s object-oriented philosophy, media philosophical approach to the problem of the activity of object proposed by Valery Savchuk and the theory of self-organisation and autopoiesis of the social systems worked out by Niklas Luhmann. The analysis of digital objects activity demonstrates two levels of functioning. The first one, fictional level, reveals mainly (but not only) in the computer games and concerns the content of media, when we gain a habit to interact with digital objects/characters as if they are real. The second level, operational, realises in the digital environment in general and concerns the form of media. On this level, glitches and bugs have crucial meaning, because they might evoke the changes in the digital world organisation, starting from the local decisions for the certain program (e.g. the elaboration of the new ways in solving locomotional tasks in simulations, which might be later use in other projects) and ending with the replacement of practices and representations typical for the human of digital era. The paper shows that it is possible to talk about digital evolution not in terms of the history of technological inventions, but in terms of the changes in digital objects caused by the inner logic of media, independently from the human will and expectations.

Development of novel therapeutics to treat antibiotic-resistant infections, especially those caused by ESKAPE pathogens, is urgent. One of the most critical pathogens is P. aeruginosa, which is able to develop a large number of factors associated with antibiotic resistance, including high level of impermeability. Gram-negative bacteria are protected from the environment by an asymmetric Outer Membrane primarily composed of lipopolysaccharides (LPS) at the outer leaflet and phospholipids in the inner leaflet. Based on a large hemi-synthesis program focusing on amphiphilic aminoglycoside derivatives, we extend the antimicrobial activity of 3′,6-dinonyl neamine and its branched isomer, 3′,6-di(dimethyloctyl) neamine on clinical P. aeruginosa, ESBL, and carbapenemase strains. We also investigated the capacity of 3′,6-homodialkyl neamine derivatives carrying different alkyl chains (C7–C11) to interact with LPS and alter membrane permeability. 3′,6-Dinonyl neamine and its branched isomer, 3′,6-di(dimethyloctyl) neamine showed low MICs on clinical P. aeruginosa, ESBL, and carbapenemase strains with no MIC increase for long-duration incubation. In contrast from what was observed for membrane permeability, length of alkyl chains was critical for the capacity of 3′,6-homodialkyl neamine derivatives to bind to LPS. We demonstrated the high antibacterial potential of the amphiphilic neamine derivatives in the fight against ESKAPE pathogens and pointed out some particular characteristics making the 3′,6-dinonyl- and 3′,6-di(dimethyloctyl)-neamine derivatives the best candidates for further development.

Introduction. Mathematical methods and models are an effective tool for studying complex economic systems at different levels of enterprise management. Economic mathematical modelling is actively developing not only as a scien-tific field but also as a means of substantiating management decisions in business, in the analysis and forecasting of socio-economic processes and phenomena. In the arsenal of economic and mathematical modelling now are using- modern computing methods and computer technology. Libraries of economic and mathematical models are an integral part of the architecture of decision support systems in specific areas of the economy. The rapid development of computer technology stimulates the emergence and formation of new theoretical volumes and applied areas of modelling.Purpose. Like any large and complex field of knowledge, mathematical modelling is evolving in different direc-tions, acquiring new flexible research methods. Therefore, based on new hardware, technology and software platforms it is necessary to create new information systems using economic and mathematical models in particular for forecasting of enterprise activities.Results. The article analyses the methods of modelling and forecasting the enterprise, considers the principles of software design. Using systems analysis, the design problem was analytically divided into parts. Also were investigated the connections and relationships between these parts, in particular, were implemented the problem tree and the goal tree. Implemented business process modelling performs based on created structural-logical diagrams, namely the IDEF0 dia-gram, which helps to visually display data and information that affect software development, a server part, input data and users. Using the results of research, the authors developed an automated information system for modelling and forecasting the activities of the enterprise, which uses models of Holt, Brown, exponential smoothing and Box-Jenkins for modelling. Part of the developed system is a designed software product that implements the objectives of the research. The obtained program results allow creating a clear forecast of the future activities of the enterprise.Conclusions. Based on the built graphs of modelling and forecasting of the Cisco Systems company financial activity with using of the developed automated system, we established that the Brown model is the best for providing educational sampling and a forecast of activity. The development of the automated system in the future involves the expansion of functionality, improvement and increasing of quality, as well as the creation of powerful analytics for more detailed forecasting.

Two tetradentate dibasic chelating Schiff base iron (III) chelates were prepared from the reaction of 2,2′-((1E,1′E)-(1,2-phenylenebis(azanylylidene))bis(methanylylidene))bis(4-bromophenol) (PDBS) and 2,2′-((1E,1′E)-((4-chloro-1,2-phenylene)bis(azanylylidene))-bis(methanylylidene))bis(4-bromophenol) (CPBS) with Fe3+ ions. The prepared complexes were fully characterized with spectral and physicochemical tools such as IR, NMR, CHN analysis, TGA, UV-visible spectra, and magnetic moment measurements. Moreover, geometry optimizations for the synthesized ligands and complexes were conducted using the Gaussian09 program through the DFT approach, to find the best structures and key parameters. The prepared compounds were tested as antimicrobial agents against selected strains of bacteria and fungi. The results suggests that the CPBSFe complex has the highest activity, which is close to the reference. An MTT assay was used to screen the newly synthesized compounds against a variety of cell lines, including colon cancer cells, hepatic cellular carcinoma cells, and breast carcinoma cells. The results are expressed by IC50 value, in which the 48 µg/mL value of the CPBSFe complex indicates its success as a potential anticancer agent. The antioxidant behavior of the two imine chelates was studied by DPPH assay. All the tested imine complexes show potent antioxidant activity compared to the standard Vitamin C. Furthermore, the in vitro assay and the mechanism of binding and interaction efficiency of the tested samples with the receptor of COVID-19 core protease viral protein (PDB ID: 6lu7) and the receptor of Gram-negative bacteria (Escherichia coli, PDB ID: 1fj4) were investigated using molecular docking experiments.

Full textAbstract:
In this paper, the hybrid PVT double pass system with a mixed-mode solar dryer type under forced convection has been designed, fabricated and installed for drying crops. The dryer was tried by drying 300 grams of banana slices in the air temperature of dryer range from 43.2 to 60.2°C. The initial moisture rate of banana was about 78% and the most dropped in moisture content was from 78% to 33% after 8 hours of the drying process. The banana slices are distributed in two identical trays and it was noticed that the most and least decreasing in weight of banana samples was from 150 to 48 gram and from 150 to 55 gram in lower and upper tray respectively, when the mass flow rate as 0.031 and 0.017 kg/s, which means that the high reduction was 68% of weight banana at a high mass flow rate of airflow. The critical parameter such as temperature distribution of the PVT with dryer room, useful heat gain, and thermal efficiency are computed by using the MATLAB 2015b program built for this purpose. The optimum useful heat gain and thermal efficiency were reached 423.7 and 52.98% respectively when the solar radiation 1190 and the mass flow rate of 0.031 kg/s.

The work is devoted to predicting and studying biological properties of N-substituted analogs of 3,5-diamino-1,2,4-thiadiazole, which, in their turn, include in the composition of many drugs that exhibit a wide range of pharmacological actions. For searching of new alternative drugs with an antibacterial activity, but lacking resistance of microorganism strains to them, a computer screening of 2N-alkyl-substituted 5-amino-3-imino-1,2,4-thiadiazolines previously synthesized by us was carried out. The prediction of the spectrum of biological activity, as well as the determination of the probable toxicity of these compounds, was performed using the freely available computer programs PASS, Anti-Bac-Pred, and GUSAR. The study of the antibacterial activity in vitro against gram-positive (Staphylococcus aureus, Staphylococcus saprophyticus, Staphylococcus epidermidis) and gram-negative (Escherichia coli, Pseudomonas aeruginosae) bacterial strains was performed by the disco-diffusion method. Experimental data roughly correspond to the predictions.

The study aimed to reveal the role of employing the PERT method in planning academic leadership training programs in Saudi universities. The PERT method was also applied in the aspect of time and cost on EXCEL software, one of PERT's computer software, in planning a training program for academic leaders in Saudi universities with the aim of ensuring its implementation in the least time and lowest cost and achieving the highest possible efficiency and quality. Whereas, the PERT method was employed in the technical aspect of time and cost in planning a training program for academic leaders in Saudi universities to ensure its implementation in the least time and lowest cost and to achieve the highest possible efficiency and quality. To achieve this, the descriptive approach was used, and the most prominent findings of the study were that the total time estimated to plan the training program according to Bert is (18) days and at a cost of 2670, unlike what was traditionally planned at (20) days and the cost of (3000), as well as Bert's applied steps showed that the possible paths on the network for the program application steps amounted to 3 paths. Path (C) represents the critical path for taking longer in implementation. There is many technical software that enable decision makers based on planning training pro-grams to reduce the duration of preparing a program plan with the least percentage. There are mistakes, especially in large training programmers, and the study recommended the need to work on employing scientific methods in planning the completion of training programs approved by universities, because the use of these methods achieves effective results in reducing time and cost.

Full textAbstract:
Despite the fact that the majority of applications encountered in practice today are captured more efficiently by RAM programs, the area of secure two-party computation (2PC) has seen tremendous improvement mostly for Boolean circuits. One of the most studied objects in this domain is garbled circuits. Analogously, garbled RAM (GRAM) provide similar security guarantees for RAM programs with applications to constant round 2PC. In this work we consider the notion of gradual GRAM which requires no memory garbling algorithm. Our approach provides several qualitative advantages over prior works due to the conceptual similarity to the analogue garbling mechanism for Boolean circuits. We next revisit the GRAM construction from (In STOC (2015) 449–458) and improve it in two orthogonal aspects: match it directly with tree-based ORAMs and explore its consistency with gradual ORAM.

Recently, IT specialties have become one of the most demanded specialties in the world labor market. Simultaneously the traditional teaching in conditions of mass production, even with a professional teacher, has a significant drawback – the fundamental impossibility of adapting to each student. Since the 60s of the twentieth century, researchers worldwide have been developing various computer-tutoring tools that have, less or more, adaptive functions. Nevertheless, the task of the perfect computer tutor development is still far from being solved.

Most published tests of knowledge and skill do not fit the instructional content, setting, and audience of specific diabetes education pro grams, so diabetes education program direc tors must develop their own. A computerized item bank of diabetes test questions can save the program director time in constructing appro priate tests by taking advantage of computers and compatible software for entering, sorting, and retrieving test questions; analyzing results; revising items; and printing a master copy of the test for reproduction. Such an item bank of diabetes- related test questions is described, and procedures for requesting test ques tions from the item bank are included.

GRAPH MODEL FOR MINIMAL DISTANCE AND OPTIMAL CIRCULATION IN URBAN DESIGNABSTRACT Among the important aspects in urban design are minimal distance and optimal circulation of the traffic network which include good access to the places of interests. The main road network is modeled in graph where the important places are represented by vertices and the main roads between them are represented in edges. A graph is called 3-connected if for every pair of vertices, there are three disjoint paths connecting them. Given the vertices and their locations, this paper focuses to make a 3-connected graph with minimal distance connecting them. This model is simulated in a computer program and applied in a current road network of Manado City, North Sulawesi Indonesia to see whether of not the road network in Manado is already optimal or not. Keywords: graph, n-connected, minimal distance, urban design. MODEL GRAF UNTUK JARAK MINIMALDAN SIRKULASI OPTIMAL PADA PERANCANGAN KOTA ABSTRAK Diantara aspek penting dalam perancangan kota adalah jarak yang minimal dan sirkulasi yang baik dari lalu lintas termasuk aksesibilitas dari tempat-tempat penting. Perancangan ini dimodelkan dalam bentuk graf yang simpul-simpul mewakili tempat-tempat penting sedangkan sisi-sisi menyajikan jalan-jalan yang menghubungkan tempat-tempat tersebut. Sebuah graf dikatakan terkoneksi-3 jika untuk setiap pasangan simpul, terdapat 3 jalur saling lepas yang menghubungkan kedua simpul itu. Fokus dari paper ini adalah, jika diberikan simpul-simpul bersama lokasinya, membuat graph yang terkoneksi-3 dengan jarak minimal. Model ini diimplementasikan dalam bentuk program komputer dan diterapkan pada jaringan jalan yang ada di Manado, Sulawesi Utara, Indonesia, sekarang untuk menentukan apakah jaringan jalan di Manado sudah optimal atau belum. Kata kunci: Graf, terkoneksi-3, jarak minimal, perancangan kota

Full textAbstract:
A programming contest generally involves the host presenting a set of logical and mathematical problems to the contestants. The contestants are required to write computer programs that are capable of solving these problems. An online judge system is used to automate the judging procedure of the programs that are submitted by the users. Online judges are systems designed for the reliable evaluation of the source codes submitted by the users. Traditional online judging platforms are not ideally suitable for programming labs, as they do not support partial scoring and efficient detection of plagiarized codes. When considering this fact, in this paper, we present an online judging framework that is capable of automatic scoring of codes by detecting plagiarized contents and the level of accuracy of codes efficiently. Our system performs the detection of plagiarism by detecting fingerprints of programs and using the fingerprints to compare them instead of using the whole file. We used winnowing to select fingerprints among k-gram hash values of a source code, which was generated by the Rabin–Karp Algorithm. The proposed system is compared with the existing online judging platforms to show the superiority in terms of time efficiency, correctness, and feature availability. In addition, we evaluated our system by using large data sets and comparing the run time with MOSS, which is the widely used plagiarism detection technique.

The objectives of this research were two: first to investigate experimentally the behavior of pineappl (Ananas comosus, L.) thin layer drying in a greenhouse-type solar dryer and second to describe the best fitting kinetic and mathematical model taken from literature. A large scale greenhouse dryer designed and installed at Silpakorn University, Nakhon Pathom, Thailand was used to dry slices 1 cm width at temperature range between 25-60 °C with relative humidity between 50-90%. Nine statistical models, either empirical or semi-empirical, were tested in order to validate the experimental data. A non-linear regression analysis conducted by a statistical computer program was applied to evaluate the constants of all the models. The parameter values, root mean square error (RMSE), mean absolute error (MAE) and modelling efficiency (EFF) of the nine models were calculated. Comparison outcomes of two experiments are displayed between the predicted moisture content and the observed pineapple moisture content. Hasibuan and Daud drying model proved to describe the best pineapple solar drying curves. The two experiments were carried out on sunny days, the second experiment on the third day showed cloudiness decreasing the solar radiation. Mathematical models of pineapple drying in a greenhouse dryer have not been found so far in the literature. Drying curves obtained from experiments showed that the constant drying and the falling drying rate periods exist. Nine thin-layer drying models were fitted to two experimental data in order to describe the drying characteristics of pineapple founding that the Hasibuan and Daud model was the best fitting.

Seeking new forms of expression in computer music, a small number of laptop composers are braving the challenges of coding music on the fly. Not content to submit meekly to the rigid interfaces of performance software like Ableton Live or Reason, they work with programming languages, building their own custom software, tweaking or writing the programs themselves as they perform. Often this activity takes place within some established language for computer music like SuperCollider, but there is no reason to stop errant minds pursuing their innovations in general scripting languages like Perl. This paper presents an introduction to the field of live coding, of real-time scripting during laptop music performance, and the improvisatory power and risks involved. We look at two test cases, the command-line music of slub utilising, amongst a grab-bag of technologies, Perl and REALbasic, and Julian Rohrhuber's Just In Time library for SuperCollider. We try to give a flavour of an exciting but hazardous world at the forefront of live laptop performance.

Full textAbstract:
The authors present the assessment of determining the deformation marks’ coordinates accuracy at constructing a network in the form of a linear spatial intersection. Using the distance between the control points and deformation marks; their coordinates are defined. The root- and general mean-square errors in determining the coordinates arising from the faults in measuring the lengths and depending on the shape of the spatial intersection are calculated. Computational mistakes enable assessing the possibility of obtaining the desired results at designing a network of deformation marks with an accuracy that meets the requirements of regulatory documents, and taking the expected accuracy of linear measurements into account. Selecting the marks is shown by the example of an elementary model. Two computer programs for that purpose were developed. The convergence of the results obtained in the course of the programs and theoretical modeling indicates the correct operation of the software. The developed algorithm and pro-grams enable optimizing the location of deformation marks at designing a network.

Full textAbstract:
A broad scope of application of corpus technologies indicates their importance in applied linguistics. Employing the comparative-contrastive method and the method of computer analysis, the author seeks to compare and contrast the main corpus tools of the programs Sketch Engine, AntConc, and WordSmith Tools, focusing on texts from specialized periodicals about cinematography ‘Total Film’ and ‘American Cinematographer’ for 2019–2020. The primary goal of this comparison is to provide recommendations for optimal choice of tools and programs for obtaining certain types of information. The author processed the total volume of texts that contained over 900,000 words, using the functions “concordance”, “word list”, “collocations” + “word s etch”, “N-grams”, “keywords” in Sketch Engine and AntConc (Word-Smith Tools has only “concordance”, “wordlist,” and “keywords”). Information about specific tools available in various corpora is collected and presented in a specially developed table. Different software programs described in the article have functions that perform the same tasks, but there are some differences in how data is presented. Among the software programs featured in this case study, the Sketch Engine platform gives the most options for choosing personal settings. The “concordance” function shows the word in context, “Wordlist” shows all the words on a given list with a record of their frequency in the corpus. The “collocation” function (or “word s etch”) recognizes fixed expressions, “N-grams” finds phrases that comprise a certain number of elements, while the “ eywords” function allows users to identify words that are specific to a particular subject area. Information thus obtained from the corpora may be helpful in updating English LSP dictionaries and glossaries of cinematography. The theoretical significance of the present study lies in systematizing the material about existing corpus tools, while its practical value is in using the tools of three corpus programs for the study of cinematic discourse, understood here as language used by the community of movie goers and filmmakers in their discussions of cinematography in specialized periodicals ‘Total Film’ and ‘American Cinematographer’.
