Published: November 2019

Abstract
The article discusses a synthesis algorithm for objects with identification and parameter tuning. The algorithm is made on the basis of software and is tested for the formation of control effects in distillation column control circuit used in oil and gas processing production. It is shown that the control method suggested for a distillation column is not less effective in comparison with a control method that pre-tuned a preset proportional and integral differential controller. The suggested controller parameter tuning is not required and is made as the mentioned algorithm functions. Moreover, in the article it is possible to find the research results of testing in conditions of various level noise, control limitations, and controlled object parameter shift.

Published: November 2019

Abstract
Fly ash based hybrid geopolymers (HGP) containing different type of mineral admixtures such as portland cement (PC), kaolin and metakaolin (MK) were developed in this study. The improved values of compressive strength, water absorption and water resistance for PC-modified hybrid geopolymers versus MK-modified HGP and reference mix was observed. High-temperature treatment (600 °C) enables to boost compressive strength by 177 % and 55 % as well as water resistance by 34 % and 40 % for MK-modified and kaolin modified HGP, respectively. At the same time, the PC-modified HGP demonstrated a very low thermal resistance, which was confirmed by a rapid drop of compressive strength and distracted structure of the specimen subjected to high temperature.

Published: November 2019

Abstract
The increase in the number of vehicles every year covers an growing number of countries, as a result of which the vehicle fleet of large cities and megalopolises is constantly increasing, as well as the number of people involved in traffic. The growth in traffic leads to the increase in traffic intensity, which in the conditions of cities with historically developed buildings leads to a transport problem. It is particularly acute in the nodal points of the road network. The problems are caused by the increase in transport delays, queuing and congestion, which in turn causes the decrease in the speed of communication, unnecessary consumption of fuel and increased wear of components and assemblies of vehicles. Effective traffic management involves the use of both network and local adaptive control algorithms. City-wide automated system should be based on the principles of maximum management efficiency and reliability of the system.

Authors: Stupina A A , Pavlenko A A , Tikhonenko D V , Tynchenko V V , Bukhtoyarov V V , Tynchenko S V 
Published: November 2019

AbstractThe use of randomness in the spread of points in the R40space gives doubts about the stability of using these spreads and the stability of global optimization algorithms predictions that are based on these spreads. The uniformity of the following initial points scatter algorithms is analyzed: LPτ sequence, UDC sequence, uniform random spread in R40. The uniformity of the spread was determined by the distance of the points from the centers of the grid cells in two-dimensional coordinate planes of the R40cube space and by the uniformity of the projections of the points on the coordinate axes in these planes. The authors identified the features of using the points spread algorithms when the number of points is multiple to two and not multiple to two. The UDC sequence is the best initial point spread algorithm in the R40space by two uniformity factors. LPτ sequence is at the second place and recently used uniform random scatter is at the third place.

Published: November 2019

Abstract
The genetic algorithm is one of the most well-known and frequently used global optimization algorithms. The software implementation of the algorithm in many programming languages and the development of various modifications of the selection parameters only encourage authors to analyze the GA parameters and search for their optimal values. Many works are trying to answer the question: what values of input parameters should be used for a greater likelihood of successfully finding the result. However, they only consider a specific set of parameters. This article describes the entire set of GA output parameters and draws up a recommendation for choosing initial values. Favorable sets of parameter values were found. Based on these sets, it is possible to customize them for specific tasks. This study provides an example of using these sets to solve the problem of determining the parameters of a welded beam. The results were obtained corresponding to the best values of similar studies. It is important to note that in solving this problem, an initial set of parameters was already formulated, which facilitated the search for a global minimum.

Frames, their relatives and reproducing kernel Hilbert spaces
Authors: Speckbacher Michael , Balazs Peter 
Published: November 2019

Abstract
This paper considers different facets of the interplay between reproducing kernel Hilbert spaces (RKHS) and stable analysis/synthesis processes: first, we analyze the structure of the reproducing kernel of a RKHS using frames and reproducing pairs. Second, we present a new approach to prove the result that finite redundancy of a continuous frame implies atomic structure of the underlying measure space. Our proof uses the RKHS structure of the range of the analysis operator. This in turn implies that all the attempts to extend the notion of Riesz basis to general measure spaces are fruitless since every such family can be identified with a discrete Riesz basis. Finally, we show how the range of the analysis operators of a reproducing pair can be equipped with a RKHS structure.

Published: November 2019

Abstract
Facilities for the storage of nuclear fuel are distinguished from other objects by high standards of safety in any operating conditions. A feature of these structures is the large thickness of the walls and floors. This feature should be taken into account in the calculations of seismic effects and thermal stresses caused by uneven temperature fields in concrete. In the work, calculations of joint effects on the building of thermal stresses and earthquakes are made. The calculations allowed us to distinguish the features of the deformation of concrete structures.

Published: November 2019

Abstract
The intensity of fear of insecurity has increased in 21st century due to the frequency and global spread of terrorism. Homes, public infrastructures and utilities have been damaged; physical and psychological injuries inflicted; economic fortunes wrecked in a minute; many rendered homeless and lives lost as a result of terrorism and threats to terrorism. Historically, bombs and explosives have been a favourite tactic of terrorists, this is because ingredients for homemade bombs are effortlessly obtained in the open market, as are the techniques for its construction and also are easy and quick to execute. However, one area counter terrorism strategy has been universally identical is in architecture and urban planning. The aim of this paper is to reveal the need for a change in ideological approach to design by architects and planners in Nigeria in order to safeguard the environment. It discusses architectural design approach to counter terrorism in building for occupant’s safety and draws analogy from the defensive architecture of ancient times. The paramount theme is on terrorist attack with regards to explosive and bomb, the focus is on an approach that limits damage or mitigates damage rather than a blast-resistant approach. The study employed the use of case study research method with extensive review of literature of the past and present approach to counter terrorism. The result highlights some practical security design strategy that will improve occupant’s safety within a structure if incorporated in architectural designs. This will also facilitate evacuation efforts and enhance rescue endeavour in an unlikely incidence of terror attack. It concludes and advocate for a proactive design strategy for buildings in Nigeria.

Published: November 2019

Abstract
Ability to afford a decent house is a critical aspect of human well-being. This study seeks to understand housing affordability among low-income earners in Akure, Ondo State, Nigeria. We conducted a survey that involves administering questionnaire to 100 randomly selected Akure residents who are employed in the junior category within public and private organisations. Most of the respondents – over 73% have monthly household income under N100,000. 81.3% of the respondents live in rented houses, while 13.3% owned where they lived. Being able to afford decent housing is a challenge as 90.7% of the respondents spent up to 25% of their total household income on rent. Majority (62.7%) agreed that their housing is not affordable, as paying rent affects spending for other household needs especially, children’s school fees and food. We recommend that stakeholders need to provide incentives towards affordable housing for their employees in the junior cadre.

Published: November 2019

Abstract
Recently, both Private and Government Developers embarked on drastic redevelopment of residential housing conversion into commercial and public buildings. However, the changes do not take into considerations social, physical and economic factors. The non-compliance with building regulations and enforcement of designated land use has considerably affected the quality of life for the residents. As an Architectural response, this study examines housing redevelopment and its impact on Asokoro District of Abuja, Nigeria. A quantitative method was adopted in this study, using structured close-ended questionnaires as a means of collecting data. A total of 190 questionnaires were distributed to residents. However, only 180 valid responses were ultimately retrieved. Among the variables examined in this study are (i) The main land uses (ii) the extent of conversion of residential housing into commercial buildings (iii) the reason for conversion and (iv) the socio-economic/environmental implication of the conversion in the study area. The findings indicated that people embarked on Housing redevelopment and conversion in order to provide basic commercial amenities that were not provided by Government. The studies concluded by identifying among others the non-approval of redeveloped buildings plan on already approved building plots as this is contravening in the image of the appropriate authorities.

Abstract
All projects regardless of complexity, have a documented start and end date. However, some projects may close prematurely because predefined goals cannot be met within the defined schedule. Negligence by one a more project stakeholders can result in premature project closure. This study examines how clients contribute to premature project closure in construction projects within South Africa. The nature of the study is descriptive which was carried out through survey research. A Likert scale structured questionnaire was used to collect data from construction professionals within Gauteng Province of South Africa and retrieved data were analyzed using descriptive statistics. The results revealed that the major clients’ actions that can lead to premature project closure include untimely allocation of resources and setting of unrealistic goals. It was therefore concluded that clients must ensure that projects are properly planned, and the predefined project design and timeline must be appropriately adhered to without much interference. This will reduce the risk of premature project closure.
