This paper describes the work of JPS+ algorithm and puts forward its modifications allowing to reduce pathfinding time. We propose to use a visibility graph to modify the map pre-processing logic at the stage of Primary Jump Points calculation. The paper also puts forward modifications in the shortest path algorithm solved for two points: the logic of Target Jump Points work and Primary Jump Points filtering has been altered to deal with obstacles. We propose an open-source software solution that accommodates the modifications.","PeriodicalId":373840,"journal":{"name":"Proceedings of the 3rd International Conference on Applications in Information Technology","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117123627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A modification of the positional optimization approach to the optimal control of feedback type synthesis is suggested. The problem of nonlinear control is reduced to a problem of optimal control for an auxiliary linear approximation system at each step of algorithm, and then to a linear programming problem. If the time to solve the auxiliary linear problem does not exceed the algorithm time step, we can say that the control system realizes the positional control in real time. The proposed method is illustrated with an optimal control problem for the mathematical pendulum.","PeriodicalId":373840,"journal":{"name":"Proceedings of the 3rd International Conference on Applications in Information Technology","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120956644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review, we examine most common approaches to sentiment analysis in microblogs and explain their advantages and weaknesses. We also review approaches to assessing credibility in news headlines and political statements and discuss their applicability in microblogs. Distinct characteristics of microblog posts, such as slang, emoticons, poor grammar and spelling are in the focus of the evaluation. Such properties of microblog messages deteriorate the performance of conventional classifiers and limit their use in practical applications.","PeriodicalId":373840,"journal":{"name":"Proceedings of the 3rd International Conference on Applications in Information Technology","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125266987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we design four pipelined asynchronous circuits for a commercial FPGA. We also describe the modeling method and the design flow.

Instead of directly considering the problem of finding an integer m such that Q = [m]P, where Ē is an elliptic curve defined over Fp of order a prime l, and P, Q ∈ Ē (Fp), we rather consider two such problems. Using the p-adic elliptic logarithm, we mainly show that finding m amounts to finding good approximations, at orders for which we provide an explicit upper bound, of the liftings of the different points considered in some groups of the filtrations of neighborhoods of the point at infinity of the lifting of the elliptic curve over Qp. We do not claim to solve the ECDLP, but rather to provide an interpretation of the problem in a context that may turn out to be useful, if one can find an efficient method to concretely capture the approximations at the appropriate order.","PeriodicalId":373840,"journal":{"name":"Proceedings of the 3rd International Conference on Applications in Information Technology","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132423508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, there are many online platforms where programmers compete and solve programming problems. Those platforms are composed of problems with varying degree of difficulties. For expert programmers, the difficulty level is not a concern, but it is very important for novice programmers to approach programming problems based on their experience and level. Thus it is important to construct an expert system which can categorize the programming problems based on their difficulties. In our research, we have proposed an expert system which is based on fuzzy rules derivation. These fuzzy rules have been derived by performing cluster analysis on submission log data of Aizu Online judge database. Different clustering algorithms were examined based on the features of these programming problems. The performance of the expert system was compared with 3 different learning models (Decision tree, Random forest, K-nearest neighbor). A high accuracy score on the testing set proves the validity of our constructed fuzzy rules for the expert system.","PeriodicalId":373840,"journal":{"name":"Proceedings of the 3rd International Conference on Applications in Information Technology","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116522904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The third element is a software system working on the host computer that can be considered as a bridge between a robot, end-user and external world. The work presented is devoted to designing the WEB-based execution environment following to topics mentioned above third item. Our attention is oriented to end-user application extending possibilities of the on-line userâĂŹs control via the WWW-based interface.
