On the positive experience of using the possibilities of the explosive laboratory of the Forensic Center of the Main Directorate of the Ministry of Internal Affairs of Russia in St. Petersburg and the Leningrad Region in terrorist crimes detection and investigation

This article is devoted to the description of the still functioning explosive laboratory created in the structure of the Expert and Technical Department of the Criminal Militia Service of the Central Government of St. Petersburg and the Leningrad Region. The main tasks carried out by the employees of the 10th department of the State Economic Department of the Ministry of Internal Affairs of Russia in St. Petersburg and the Leningrad Region (department of explosive and fire and technical expertise) are highlighted. Special attention is paid to the participation of these employees in crime scenes investigation of offences involving using explosive objects with subsequent explosive expertise. The author provides examples of high-profile criminal cases. In addition, the author underlines the significant role of interaction of the laboratory under consideration with various law enforcement services for highly efficient expert support in the investigation of crimes related to the illicit trafficking of explosive objects, as well as in solving complex and far from secure operational tasks in order to further scientific and practical development for needs of law enforcement agencies (emphasis is placed on scientific researches of the employees of the 10th department of the Forensic Center).

Scalable Blockchain-assisted Log Storage System for Cloud-generated Logs

During the normal operation of a Cloud solution, no one pays attention to the logs except the technical department, which may periodically check them to ensure that the performance of the platform conforms to the Service Level Agreements. However, the moment the status of a component changes from acceptable to unacceptable, or a customer complains about accessibility or performance of a platform, the importance of logs increases significantly. Depending on the scope of the issue, all departments, including management, customer support, and even the actual customer, may turn to logs to find out what has happened, how it has happened, and who is responsible for the issue. The party at fault may be motivated to tamper the logs to hide their fault. Given the number of logs that are generated by the Cloud solutions, there are many tampering opportunities. While tamper detection solution can be used to detect any changes in the logs, we argue that the critical nature of logs calls for immutability. In this thesis, we propose a blockchain-based log system, called Logchain, that collects the logs from different providers and avoids log tampering by sealing the logs cryptographically and adding them to a hierarchical ledger, hence, providing an immutable platform for log storage.

A Review on Test Automation for Test Cases Generation using NLP Techniques

In the process of product development, stakeholders and top management summarize the concept and document the requirements in natural language. These ideas and descriptions documented as software requirements by the technical department. Developers develop software following this software requirement document. For testing this developed software, they derive test cases from natural language requirements and then do the testing process to find the bugs. This process involves understanding requirements and derives test cases that are used to understand by developers and testers. Due to increasing the advanced features, deriving the test cases is monotonous and takes more time. This research article shows a method to automate this process which is deriving test cases from requirements using NLP algorithms. This approach useful to reduce the time and cost of software development.

Architect Hans Hopp (1890–1971): at the sources of formation of the center of modern Kaliningrad

Статья посвящена сооружениям архитектора Карла Густава Ханса Хоппа (1890–1971), активно строившего в 1920-е годы в столице Восточной Пруссии Кенигсберге (совр. Калининград). Х. Хопп принадлежал к числу немногочисленных приверженцев авангарда, работавших в отдаленной консервативной провинции Германии. Созданные им сооружения маркируют центр города, сместившийся от территории бывшего кенигсбергского замка и возведенного на его месте в 1974 году Дома Советов (архитектор Ю. Шварцбрейм) на современную площадь Победы, занявшую место Восточной ярмарки. Как руководитель технического отдела ярмарки, игравшей важную роль в возрождении экономических связей между Германией и Россией, архитектор возвел в трудные годы после окончания Первой мировой войны целый ряд сооружений. Здания в стиле сдержанного экспрессионизма с элементами ар-деко – Торговый двор для фирм-участников ярмарки (современное здание мэрии) и Дом Техники (современный торговый центр «Эпицентр») определяют границы и образный строй центральной части столицы Калининградской области. Мастер придерживался радикальных новаторских взглядов на формальную природу современного ему художественного творчества, организовал в своей квартире-галерее выставку представительницы раннего экспрессионизма П. Модерзон-Беккер, дружил с автором исследования «Абстракция и вчувствование» В. Воррингером, преподававшим в 1928–1944 годах в Кенигсбергском университете. Монументальные строения архитектора украшают экспрессионистические работы скульптора Г. Брахерта (1890–1972). В конце 1920-х годов архитектор увлекся формальными приемами школы Баухаус и украсил Кенигсберг необычными для города зданиями (ремесленная школа для девушек, Парк-отель и другие). The article is devoted to the constructions of the architect Karl Gustav Hans Hopp (1890–1971), who was actively building in the 1920s in the capital of East Prussia Konigsberg (modern Kaliningrad). H. Hopp was one of the few adherents of the avant-garde who worked in the remote conservative province of Germany. The structures created by him mark the center of the city, which has shifted from the territory of the former Koenigsberg castle and built in its place in 1974 by the House of Soviets (architect J. Schwarzbreim) to the modern Victory Square, which took the place of the Eastern Fair. As the head of the Technical Department of the fair, which played an important role in the revival of economic relations between Germany and Russia, the architect erected a number of structures in difficult years after the end of the First World War. Buildings in the style of restrained expressionism with elements of Art Deco – Torgovy Dvor for the companies participating in the fair (modern city hall building) and the Technique House (modern shopping center “Epicenter”) determine the boundaries and the imagery of the central part of the capital of the Kaliningrad region. The master adhered to radical innovative views on the formal nature of contemporary art, organized in his apartment gallery an exhibition of the representative of early expressionism P. Moderson-Becker, was friends with the author of the study “Abstraction and Feeling” V. Warringer, who taught in Koenigsberg from 1928–1944 university. The monumental buildings of the architect are decorated with expressionist works of the sculptor G. Brachert (1890–1972). In the late 1920s, the architect became interested in the formal techniques of the Bauhaus school and decorated Koenigsberg with unusual buildings for the city (Craft School for Girls, Park Hotel and others).

The genesis of the use of service animals and special equipment in the conduct of operational investigative activities

The article deals with research of development of means of operational-search activities (OSA) from ancient times to the present. The stages of the development of OSA tools, including service animals and special equipment, their dependence on scientific and technological progress and the role in combating crime have been considered. The author has concluded that the genesis of the use of service animals suggests that: 1) for many years (from the second century BC) in the law enforcement system used different species of animals, including geese, horses, rats, dogs, etc .; 2) the process of formation of the use of dogs in law enforcement went from the use of the latter in hunting and military affairs to the gradual occupation of a separate link in the structure of law enforcement, in particular dogs began to be used on a professional basis to search for odors, data transmission , protection of objects and people, detention of offenders, etc .; 3) analysis of the practice of using animals allows us to state that the largest and oldest role in law enforcement was played by dogs. From its immergence to the present day, the means of operational and investigative activities are in a state of constant development and improvement. Scientific and technological progress has turned covert means of obtaining information into one of the most effective tools for combating crime. For example, the capabilities of the operational and technical department of the Main Department of the State Tax Service in Dnipropetrovsk region will allow to simultaneously control a significant number of telephone lines, which allows you to effectively confront a permanent organized criminal group, especially at the stage of prepa-ration for crime. The use of such powerful tools on the one hand allows to obtain a huge array of information about the phenomena and processes occurring in the criminal environment, and therefore requires a significant number of experienced professionals to process it and extract information relevant to combating crime. On the other hand, along with information on training and enforcement, law enforcement agencies inevitably receive information on the honor and dignity of citizens that is irrelevant to pre-trial investigations, posing a real threat of abuse. Thus, the requirements for the impartiality of law enforcement officers increase, and the legislator is faced with the task of significantly improving the existing legal framework regulating opera-tional and investigative activities.

Specialists for Modernisation. Discussion about Training of Specialists for the Electro-Technical Industry in Russia on the Cusp of 19th-20th Centuries

The article is dedicated to the topic, which is important at present time: formation of human capital as an important factor of the social and economic development of society. Modernization of education plays an essential part in terms of the development of human capital during all historical stages and its importance grows significantly alongside with the economic growth of the country. The role of education and necessity to improve its quality became of significant value for Russia during the economic modernization on the cusp of the 19th–20th centuries. In this article, the author makes an attempt to analyze the experience of formation of different levels of electro-technical education during the economic modernization, as well as to reveal the role of civil society in this process. The Russian economic modernization implied the formation of a competitive industrial complex, which included mining, manufacturing industries and transport. The electro-technical industry, which was lacking trained personnel, was the most quickly developing one. The discussion in the relevant journals as well as during the work of All-Russia electro-technical congresses set up, to the most extent, the main ways to form all the levels of electro-technical education, which helped to train personnel for the respective industry. The author analyzed both the available experience in realization of lower and secondary specialized electro-technical education and the new approaches to its organization, developed mostly in the Electro-technical department of the Emperor’s Russian Technical Society (ERTS). Apart from that, there was a curious attempt to open a higher electro-technical school in Moscow based on the European (mostly French) experience, which was oriented mostly towards additional training of the already working engineering and technical specialists.
