RECOVERY AS A MEANS OF IMPROVING THE PERFORMANCE OF TRACK-AND-FIELD ATHLETES (RACE WALKERS) AT THE STAGE OF SPORTS SKILL IMPROVEMENT

Statement of the problem. The problem of athletes’ performance recovery is most significant due to the increased sports loads for athletes. The sport of high achievements requires huge physical and emotional strength from the athlete, while the load increases. The history of the latest sports competitions proves that the load for athletes is growing. The growth of loads initiates the development of recovery tools, tools that allow athletes to maintain their shape. The use of modern tools and methods of recovery increases the potential of an athlete at the stage of sports skills improvement. It should be noted that there are very few publications devoted to new recovery tools for athletes. In this regard, this article has a special relevance. The purpose of the article is to characterize the recovery tools of track-and- field athletes (race walkers) at the stage of their sports skill improvement. The research methodology consists of an integrated approach, a generalization method, analysis of special literature on the research problem, and content analysis. Research results. The analysis made it possible to conclude that it is necessary to increase attention to the development of the methodology and technique of recovery of a track-and-field athlete. At this time in sports, the problem of recovery is important, as is training. Consequently, the methods of restoring and relieving fatigue in an athlete are of paramount importance in the modern world. A characteristic feature of sports is training loads of significant intensity and volume, which make high demands on the body of athletes. The search for the most effective means of recovery makes it possible to increase the ability of the body. Conclusion. Improving methodological and analytical tools for the recovery process of athletes is an important and urgent problem that has not been solved methodically and methodologically. In modern conditions, it is necessary to create a model for working with an athlete, where the athlete’s recovery process will be based on a scientific approach using innovative tools.

Pandemic Recovery: Tools and Solutions

This review describes what measures are being taken to restore the Russian economy after the pandemic, legislative initiatives in the field of operational safety, as well as new innovative solutions in the field of protective equipment.

Security Awareness on Ransomware Threats Detection and their Protection Techniques

Computing and smart monitoring devices or machines are involved in every organization and sector in present era. These machines have any operating system (OS), software and applications installed based on the requirement. Due to available security vulnerabilities in OS or software and applications, these machines have more chances to become victims of Ransomware attacks. Attacker demands for ransom in any form of cryptocurrency like Bitcoin and other to normalize the files and services. Ransomwares are pandemic threats globally. Paper focuses on this part of the cybersecurity issues, the latest ransomware and their variants. In our research, we tried our best to explained ransomware and millions of dollar damage done by them in the past few years. Further, we have provided different ransomware spreading and detection mechanisms. At the end of the paper, if any machine infected through ransomware so some prevention, protection and recovery tools and techniques have been mentioned.

Implementation of Anti Forensics on Hard Drives Using the DoD 5220.22 M Method and British HMG IS5 E

The process of securing data is related to anti-forensic science, one of the anti-forensic techniques that can be used to safeguard data security, namely by deleting data on storage media. This study examines the implementation of data deletion using the DoD 5220.22 M and British HMG IS5 E methods, then compares these methods. The comparison of the two methods includes performance tests, forensic tests, and data recovery tests. The results of the performance test show that the two methods are strongly influenced by the anti-forensic tools used and do not provide a significant difference when applied using one of the tools. The results of the implementation of data deletion using both methods on the hard disk drive are declared safe to delete data, as evidenced by the extraction results in the forensic test using the Autopsy tool found files on the partition :F with the number of 252 files and on the partition :I with the number of 1 file and the extraction results from the test Forensics using the Recover My File tool managed to find files with the number of 102 files on different partitions, but all the files found in the forensic test process cannot be accessed. The results of the recovery test show that the safest method in the process of deleting data is the British HMG IS5 E method using the Active @ Kill Disk tool, as evidenced by all the results of the recovery process using three tools that do not find any files. Meanwhile, the application of the deletion method that is generally carried out by users, namely the shift + delete method, is declared unsafe, as evidenced by the results of the recovery tests conducted showing that the deleted files can be recovered 100% and can be reaccessed using recovery tools.

GRACETOOLS—GRACE Gravity Field Recovery Tools

This paper introduces GRACETOOLS, the first open source gravity field recovery tool using GRACE type satellite observations. Our aim is to initiate an open source GRACE data analysis platform, where the existing algorithms and codes for working with GRACE data are shared and improved. We describe the first release of GRACETOOLS that includes solving variational equations for gravity field recovery using GRACE range rate observations. All mathematical models are presented in a matrix format, with emphasis on state transition matrix, followed by details of the batch least squares algorithm. At the end, we demonstrate how GRACETOOLS works with simulated GRACE type observations. The first release of GRACETOOLS consist of all MATLAB M-files and is publicly available at Supplementary Materials.

E-Raser: File Shredder Application With Content Replacement by Using Random Words Function

Data shredding indicates a process of irreversible file destruction while file shredder is the program designed to render computer-based files unreadable by implementing overwriting method to destroy data in the content of a file. The addressable problem with existence of file recovery tools is it may lead to data leakage, exploitation or dissemination from an unauthorized person. Thus, this study proposed a file shredding application named E-Raser which replacing the content of the file using random words function algorithm. A file shredder application named E-Raser was developed to shred Microsoft Word documents with (.doc) or (.docx) format. The implemented algorithm replaced the original content of the files with uninformative words provided by the application. After rewriting phase is complete, shredding process take place to make the file unrecoverable. Object Oriented Software Development was used as the methodology to develop this application. As a result, E-Raser achieved the objectives to add, remove, rewrite, display and shred files. Also, E-Raser is significantly facilitates users to securely dispose their file, protect the confidentiality and privacy of the file’s content.
