    Thesis: M. Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2015.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 59-61).Lowering voltage and frequency guardbands of CPU, DRAM, cache, or interconnect lowers power and latency, but increases the risk of silent data corruptions in even formally verified hardware and software. Researchers have been developing systems that use unreliable hardware, combined with software checkers executed on reliable hardware, to gain high performance with no risk. Deterministic checkers for many important algorithms are asymptotically and practically more efficient than the original problem solvers, e.g. for systems of linear equations, satisfiability, linear programming, sorting, 3SUM, graph matching and others. Writing a correct checker is hard, since often intricate corner cases get overlooked. Our system, SOUNDCHECK, helps reduce burden on programmers by automatically proving soundness and completeness of checkers with bounded verification in the Sketch program synthesis language. Verified checkers are emitted as efficient C++ code and shown to have low overhead which results in a net performance improvement with no risk.by Yoana G. Gyurova.M. Eng

    ABSTRACT Yoana Fidela (2020): The Effect of Using Cooperative Integrated Reading Composition (CIRC) Technique on Students’ Reading Comprehension of Recount Text at MAN 1 Pekanbaru Based on the researcher's preliminary study, it was found that, some students still have problems in English, especially reading comprehension in the recount text. Therefore the author is interested in conducting research on the problem. This research was conducted at MAN 1 Pekanbaru. The subjects of this study were tenth graders at MAN 1 Pekanbaru and the object of this study was the Effect of Cooperative Integrated Reading and Composition (CIRC) Against Understanding Recount Text Reading of tenth grade students at MAN 1 Pekanbaru. The type of research is Quasi-experiment. The population of this study was all tenth grade students. The total population is 326 students. Researchers took samples of class X MIA 1 consisting of 38 students as an experimental group and class X MIA 2 consisting of 36 students as a control group. So, the number of samples from the two classes is 74 students. For the data analysis, researchers used Independent sample T-test through SPSS. After the data were analyzed, researchers found the average score of students’ reading comprehension of recount text taught without using CIRC technique at the tenth grade of MAN 1 Pekanbaru were 65.83 in pre-test and 82.08 in post test, the average score of students’ reading comprehension of recount text taught by using CIRC technique at the tenth grade of MAN 1 Pekanbaru were 67.5 in pre-test and 88.82 in post test and there is significant effect of using CIRC technique on students’ reading comprehension of recount text at the tenth grade of MAN 1 Pekanbaru with score 15.6%

    Full text link
    This paper aims to show the major role means of protection play for strengthening the cybersecurity of critical transport infrastructure by using the advanced method of simulation modelling. The simulation model of a Traffic Control Centre (TTC) of an urban Automobile Transport System (ATS) is created by the author in the Riverbed Modeler Academic Edition 17.5 computer networks simulation system and is exposed to the impact of a Denial-of-Service attack. In addition, logical conclusions have been made on the basis of the experimental results obtained and evaluated by comparative analysis with results from analogous previous studies

    Full text link
    This article is considered to be a continuation of a publication by the author devoted to an algorithm for steganographic embedding of encrypted files in raster images (Yearbook Telecommunication, №9, 2022). The aim of this paper is proposing a methodology for empirical research and analysis on the field of cybersecurity which to contribute to various areas in cybersecurity. Its originality is expressed in the joint application of methods for research and analysis realized by various simulation environments for conducting experiments. This methodology has a specific structure as it is conditionally divided into two major parts depending on the type of the simulation process and software products used – a study of the direct impact of cyberattacks on communication networks by the method of the agent-based modelling and a study of potential steganography attacks using software for simulation of Artificial Neural Networks (ANNs) for the purposes of steganalysis

    This articles compares the characters of Maciek from Jerzy Andrzejewski’s "Ashes and Diamonds" and Danny from the novel "The Cowards" by Josef Škvorecký. Indeed, the two main characters are similar in behavior and evolution, despite the fact that the two novels are fundamentally different stylistically. However, the two books share one common theme: the last days of World War II in Central Europe. The analysis is divided into three parts. First, the authors’ historical, national, and bibliographical contexts are analyzed with the aim of identifying their and their novels’ situation and impact on their time and respective societies. Then, a comparison of the two novels from the point of view of style and literary genre is made to establish what differentiates them. Finally, the author of this article compares the characters of Maciek and Danny, especially their evolution and behavior, in reference to the concepts of the Peter Pan syndrome and the phenomenological theory of war from the so-called “sixth heretical essay” of the Czech philosopher Jan Patočka. Finally, the conclusion of the article shows that through these characters, the same phenomenon of self-alienation is rendered perceptible for the younger generation at the historic turning point of the end of World War II in Central Europe.DecretOANoAutActifinfo:eu-repo/semantics/publishe
