Green Project Management in the Construction Sector in Greece

Green Project Management is directly related to the practices of technical companies for the construction of technical projects based on a sustainable design with the central objective of minimizing or eliminating negative environmental impacts, saving resources and minimizing the use of non-renewable energy sources. This work is aims at investigating the current situation regarding the application of green administration and management of technical projects and highlighting the importance of this application in terms of limiting environmental pollution by the Technical Companies of the construction sector in Greece. The research was conducted by distributing a questionnaire to a random sample of 60 employees - engineers of Greek technical companies in the construction sector, with experience in the management of Technical Projects. The results of the research showed significant deficiencies in the application of green management practices of technical projects in Greece and in the improper use of raw materials and green products as well as serious deficiencies in the financing of construction companies.

The Research of Optimal Portfolio in Technology Industry Based on Arithmetic Average Return, CAPM, and Fama-French Three-factor Model

As hotspots of the stock market, technical companies are always popular to invest. In this background, this paper uses three common models in asset pricing to help the investors to make proper decisions. This paper comes to a conclusion that CAPM forecasts the ideal portfolio expected return with more accuracy than other techniques when the contrast group's time period is shorter than the experimental group's time period. Because Fama-French the three-factor model's factors don't operate over short time periods and arithmetic average return doesn't take enough market factors into account, it might not be more accurate. The conclusion in this paper takes an instruction of investment strategy to technical companies investors. Furthermore, it also helps the investors to allocate a proper portfolio.

Hierarchizing the Criteria of Construction Equipment Procurement Decision Using the AHP Method

Successful investment in construction equipment (CE) is a complex process as it involves the selection and prioritization of many criteria. Fleet managers, contractors, and technical companies search for maximum equipment profitability during the economic life of a machine. Decisions on when to replace a piece of equipment are characterized by many uncertain factors that are difficult to quantify. A literature review and a scientometric analysis are conducted, revealing a gap in the global research, concerning the hierarchy of the criteria in decision making, when coming to procure a CE. The purpose of this article is to address that void in the extant literature by proposing a holistic equipment procurement decision model. A scientometric analysis of the last 25 years is performed to investigate the use of analytical hierarchy process (AHP) in the thematic area. A modified decision model based on the AHP is developed to prioritize factors that determine decisions on equipment procurements. Unstructured interviews with academia, experts, original equipment manufacturers, and practitioners in the field are conducted in conjunction with an extensive literature review to determine the critical “soft” and “cost” factors incorporated in the model. It seems that this is the first integrated attempt to prioritize the “key” factors that determine decisions of equipment procurement.

Salary of Management Personnel of Joint Stock Electric and Technical Companies in Pre-Revolutionary Russia

The article provides the analysis of an insufficiently researched problem of incentives for the management personnel of joint stock electric and technical companies. The completed analysis of the board of directors reports of more than twenty capital-based and regional companies, which was more than one third of all joint stock electric and technical companies acting in Russia at the end of the XIX — beginning of the XX centuries, allowed to reveal the mechanism of salary payment for elected and appointed managers, including chairmen and members of management boards, managing directors and other employees in this industry. It was concluded that the management boards of companies consisted mostly of the founders and shareholders of these companies. An exception was made only with respect to the managing directors who were directly responsible for the current business activity and were expected to have proper knowledge and experience. This category of management could be formed either from the shareholders or from the invited specialists. While the incentives for the work of chairmen and members of companies were mostly bonuses and dividends, which were paid out of the net profit upon the results of the financial year, managing directors, as a rule, received a fixed salary, which could be paid monthly or as a result of the annual activity. At that, the amount of payments in different companies, irrespective of the scale of their activity, was more or less the same, which proved a unified approach for the making of the managerial capital in the industry.

Dynamic Changes in US Technical Company under Uncertain Market

Since the outbreak of the COVID-19 epidemic, great changes have taken place in the world's economic situation. The interest rate increase by the Federal Reserve has become one of the most influential actions. Researchers have found that the Fed's interest rate hike not only has an impact on the American financial market but also on the world economic situation to a certain extent. Therefore, this paper collects the share price of US dollar and the exchange rate between US dollar and RMB since June, 2021, and uses VAR model and ARMA-GARCH model to model and analyze the data, to examine how the Fed's interest rate hike will affect the dollar's value and Apple's share price, and to predict the future exchange rate and the development trend of Apple's share price in the case of the Fed's interest rate increase, so as to further study the dynamic changes of American technology companies in the uncertain market.

The rainfall data were from the Northeast Development Superintendence and the Technical Assistance and Rural Extension Company of the state of Sergipe, between 1963 and 2019. The periods 1963-1982 are used; 1983-2001 and 2002-2019, performing the rainfall trend for the respective months of the periods studied. Trend studies are accessible when analyzing long data series or split into 20-year sub-periods for a perfect understanding of their oscillations. The results found and discussed can be a beneficial tool for carrying out planning, monitoring and acts that point out the best way to manage rainfall rates to be used in agriculture, health, thermal comfort in cities, among other applications. The irregularity of rainfall distribution is limiting factors for the increase in agriculture and agribusiness under study.

Impact of global and local urbanization and social trends on the future of Kazakhstan

The article examines global and local trends in the urbanization process in Kazakhstan and the world and their impact on the future of the country. In 2007, a turning point in the urbanization of the entire world came — the milestone of 50 % was overcome, and by 2050 66 % is expected. It describes forecasts for an increase in women’s economic influence at the expense of third world countries, influence on the development of scientific and technological progress through the activities of special scientific zones or cities with a high density of technical companies, as well as the change of the global consumer base from Europe and America to the countries of Asia and Tropical Africa, the beginning of economic growth on the African continent. At the end of the XXI century, the three largest cities in the world will be in Tropical Africa — Lagos, Kinshasa, Dar es Salaam. It provides statistics on the development of urbanization in Kazakhstan, approaching the indicators of population ageing, the dangers of too rapid growth of megacities without adequate medical and educational provision. The article concerns state measures to prevent the formation of “marginal rings”, due to the growth of protest potential in the event of a social crisis, as well as the desire to reduce the outflow of population from rural areas. It reveals the prospects for the formation of agglomerations in Kazakhstan and the similarity of local trends in Kazakhstan and Russia in terms of population reduction in small and medium-sized cities and the growth in the number of large cities and megacities. Analysis of the studied material is provided.

Legal regulation of evidence in cybercrimes in UAE legislations

The study aims mainly to evaluate the legal regulation of evidence in cybercrime in the United Arab Emirates compared to the provisions of Islamic laws by explaining the concept of cybercrime, its types, elements, and ways to confront it. The study will examine the legal and judicial framework to combat cybercrime in the United Arab Emirates, and define the means, conditions, the evidentiary requirements of cybercrime in Islamic law and UAE legislation. The researcher has used the descriptive-analytical method in his research. The study concludes with several results. The most important of which is that cybercrime differs from its traditional counterpart in nature and methods of gathering evidence to prove it. The study also concludes that there are difficulties in proving electronic evidence, in addition to the fact that the UAE legislator did not provide for means of evidence for cybercrimes. The study also concludes with several recommendations. There is also a need to enact legislation that compels technical companies and social media platforms to ask users and customers to provide personal documents that prove their identities when registering on any platform on the Internet, these documents will serve as an "electronic fingerprint”.

Prediction of the Technology Company’s Stock Price through the Deep Learning Method

This work aims to utilize deep learning methods CNN and LSTM to predict the adjusted close price of eight technical companies. The proposed model is a CNN-LSTM hybrid model, which combined CNN and LSTM layers in the model. It was compared with the single LSTM model and double LSTM model to evaluate its performance. The results showed the CNN-LSTM made a great prediction and can predict a more accurate value than the other two models, but it still can be improved to reduce overfitting problems.

Dealing with the Commonplace: Constantinos A. Doxiadis and the Zygos Technical Company

This paper deals with a largely unknown episode in the prolific career of the internationally renowned planner Constantinos A. Doxiadis (1913-1975). Between 1962 and 1974, he operated the construction company Zygos S.A. with a view to take advantage of the opportunities presented by the proliferation of the polykatoikìa (a characteristic mid-rise apartment building in Greece) via antiparochì (a popular land-for-flats contract)Αs this paper analyzes, the story of Zygos offers a unique opportunity to unpack a series of important issues regarding housing production and urbanization processes in postwar Greece—and potentially other countries—where housing was neither undertaken by centralized mechanisms, nor promoted by the welfare state. It discusses how the self-propelling mechanism of antiparochì both created and drew on a system of social and economic interdependencies that enjoyed broad support across the political spectrum, while boosting the growth of a speculative real estate market, where amateurish contractors and small construction companies thrived. In fact, the growth of such a market owes a lot to the regulatory measures launched by Doxiadis while being in charge of the Greek Reconstruction and Recovery programs (1945-1951). Altogether, the story of Doxiadis’s involvement in the Greek real estate market offers a striking example of how top-down incentives and bottom-up initiatives converged to create the conditions and framework within which Greek architects (including renowned ones) routinely operated. To contextualize the design and building process of polykatoikìes (a commonplace building type outside the realm of high architectural design), the paper draws on the concept of the “commonplace” as an umbrella term used to describe the socio-economic conditions evinced in the antiparochì mechanism and the everyday lived experience of a developing urban society.

«Merger and acquisition»: monopolization of electro technical market in Russia at the beginning of the XX century

Introduction. The problem of monopolization of the electric and technical market in Russia becomes the most important one during the economic modernization at the edge of XIX–XX centuries when the branches of foreign electric and technical companies are converted into Russian joint stock companies. “Electric illumination company of 1886” becomes the largest company on this market at the beginning of the XX century. Materials and Methods. The article is devoted to the research of the policy of “Electric illumination company of 1886” aimed at the acquisition of the “Shuvalov electric illumination company in Petersburg region” of the largest electro technical company – Joint stock company “Shuvalov electro technical illumination in Petersburg region” established for the purpose of illumination of country-house plots and houses in the suburb of St. Petersburg (Shuvalovo, Ozerki and Pargolovo) at the beginning of the XX century, which is based on the analysis of the archive materials contained in the Russian State Historical Archive (RSHA) and Central State Historical Archive of St. Petersburg (CSHA SPb.). Results of the Research. Using the example of the activity of such electro technical companies the author reveals the mechanism of “merger and acquisition” of minor joint stock companies by large monopolists who used different methods of pressure on the shareholders and management of the companies. Discussion and Conclusion. In this competitor environment, minor joint stock companies did not have a chance to remain independent even in the case of a fair court decision. The situation of “merger and acquisition” was actually profitable mostly for the companies’ management and for the leading shareholders who, in this case, received regular dividends, but the common customers had to pay according to the prices set forth by monopolies.

Studies of meteorological elements and climate change in the Uruçuí river basin/Brazil

The objective is to show the variability of meteorological elements in the hydrographic basin area of the hydrographic basin of the Uruçuí Preto River–PI/Brazil, aiming to contribute to sustainable development in the productive areas of agriculture, laser, and hydrology. The meteorological elements studied are air temperature and relative humidity and their fluctuations, thermal amplitude, wind (intensity and direction), total insolation, cloud cover, evaporation, evapotranspiration, and rainfall. The data were from the 1960-1990 series, acquired by the Superintendency of the Development of the Northeast and by the Technical Assistance and Rural Extension Company of Piauí. The maximum annual temperature is 32.1°C, its minimum 20.0°C, with an average annual temperature of 26.1°C. A climatic classification was used according to the KÖPPEN systems, where two climatic types are distinguished in the Uruçuí Preto/PI river basin, the Aw, tropical hot and humid, with rain in summer and dry in winter; Bsh, warm semi-arid, with summer rains and dry winter. The variation of the thermal amplitude is from 11.9 to 14.9ºC. The average relative humidity of the air was 47 to 79%; the average annual precipitation was 937.7 mm; it was observed that the annual march of relative humidity follows the annual distribution of precipitation because the precipitation was the feeding process from natural sources of water vapor and moisture. Total Sunstroke in the BHRUP area ranges from 2520 to 2750 hours. It is concluded that the maximum annual temperatures increased during the period, which can cause several socioeconomic problems, and human health.

Assessment of Technical Condition of C Series Power Hydraulic Cylinders of Mounted Hydraulic Systems of Tractors

Introduction. The existing methods of assessing the technical condition of power hydraulic cylinders do not allow one to conclude about the need to restore worn surfaces of parts. The data on limit values of wear of parts (wear and tear value at which a decision is made to repair) in technical requirements to overhaul and other technical documentation of hydraulic cylinders are not currently available. The aim of the study is to determine limit values of wear of working surfaces of hydraulic cylinder parts of C series. Materials and Methods.To assess the technical condition of hydraulic cylinders used, the authors developed a device on the basis of the stand KI-28097M-GOSNITI, equipped with an independent hydraulic station and load hydraulic cylinder, at which bench tests were carried out in the operation of С series hydraulic cylinders to determine overall efficiency values. Results. Results of bench and micrometer tests of the former hydraulic cylinders of the С series (С75/30, С90/30, С100/40) are presented. The regression model of the relationship between total efficiency of C series hydraulic cylinders (С75/30, С90/30, С100/40) and wear of working surfaces of parts was obtained. According to this regression model obtained using the method of steep ascent, limit values of wear of the working surfaces of C series hydraulic cylinder parts (С75/30, С90/30, С100/40) were determined. Discussion and Conclusion.19,5 % of hydraulic cylinders of С series (С75/30, С90/30, С100/40) were operated in an out-of-limit condition. In case of technical service companies carrying out the input control of to-be-repaired hydraulic cylinders, limit values of wear for hydraulic cylinder surfaces, determined by the method of steep ascent, allow for making proper decisions on the need of their restoration.

Autonomous Cars: Research Results, Issues, and Future Challenges

Throughout the last century, the automobile industry achieved remarkable milestones in manufacturing reliable, safe, and affordable vehicles. Because of significant recent advances in computation and communication technologies, autonomous cars are becoming a reality. Already autonomous car prototype models have covered millions of miles in test driving. Leading technical companies and car manufacturers have invested a staggering amount of resources in autonomous car technology, as they prepare for autonomous cars’ full commercialization in the coming years. However, to achieve this goal, several technical and nontechnical issues remain: software complexity, real-time data analytics, and testing and verification are among the greater technical challenges; and consumer stimulation, insurance management, and ethical/moral concerns rank high among the nontechnical issues. Tackling these challenges requires thoughtful solutions that satisfy consumers, industry, and governmental requirements, regulations, and policies. Thus, here we present a comprehensive review of state-of-the-art results for autonomous car technology. We discuss current issues that hinder autonomous cars’ development and deployment on a large scale. We also highlight autonomous car applications that will benefit consumers and many other sectors. Finally, to enable cost-effective, safe, and efficient autonomous cars, we discuss several challenges that must be addressed (and provide helpful suggestions for adoption) by designers, implementers, policymakers, regulatory organizations, and car manufacturers.

SELECTION OF REPAIR OPTIONS FOR FAULTY REPLACEABLE COMPONENTS AND AGGREGATES INCORPORATED IN AD WME FROM THE PERSPECTIVE OF MILITARY ECONOMIC AND TECHNICAL FEASIBILITY

A main number of AD WME failures is caused by replaceable components (RCs) failures of radio-electronic equipment (REE). However, a significant part of the RCs is repairable, i.e. their operability can be restored by means of repair. The repaired RCs and aggregates from the AD WME component parts can be further returned to form a part of spare tools and accessories and used as intended to repair the AD WME component parts by an aggregate method. Until recently, a main option of faulty RCs and aggregates repair arrangement has been their delivery to industrial enterprises for repair. It resulted in delivery delays of the repaired RCs and aggregates incorporated in the AD WME pieces, a necessity to increase a number of the RCs in spare tools and accessories kits, as well as in value appreciation of the AD WME operation. Owing to creation of unified mobile organizational repair systems in JSC Principle Production and Technical Company Granit, now there is an opportunity of current repair of the faulty RCs and aggregates delivered for these purposes to deployment sites of the maintainable AD WME within the unified mobile organizational repair systems. The article considers the issues related to military technical and economic feasibility of implementing the options of RCs and aggregates repair organization: in the field environment (applying the unified and mobile organizational repair systems), at fixed-site maintenance organizations, and at manufacturing facilities.

ASPECTS OF PROTECTION OF DEVELOPMENT ENTERPRISE’S RIGHTS TO INTELLECTUAL PROPERTY ITEMS

When performing research, development, and engineering (RD&E) financed using state, regional, or municipal budget funds, legal relations between a customer and a RD&E contractor with regard to ownership of a created intellectual property are regulated by Part 4 of the Civil Code of the Russian Federation [1]. The intellectual property includes patentable innovative solutions which are qualified as intellectual property items. According to the applicable legal standards and law enforcement practice, patent protection obligations with regard to the created intellectual property items are imposed on the RD&E contractors. However, patent right holders with regard to these intellectual property items are the RD&E customers. As a result, the RD&E contractors face several difficulties, delays, and limitations with regard to patenting the intellectual property items and do not obtain necessary privileges to the full extent in connection with patenting the created intellectual property items. This article analyses the applicable procedure for distribution of the rights and obligations between the contractors and customers of the RD&E with regard to the patent protection of the created intellectual property items. Using experience of JSC Principle Production and Technical Company Granit as an example, a possibility of protecting RD&E contractors' interests by pre-emptive patenting of the intellectual property items prior to RD&E activities start is explained.
