Competing place names
Authors: Rodríguez Yliana V. , Elizaincín Adolfo 
Published: January 2023

Abstract
The ongoing Argentinian claim of sovereignty over the Falklands has impacted its toponymy by assigning the archipelago,
and places within it, different names than those used on the Islands. Place naming phenomena like this one have not received much attention.
To our knowledge, there is no prior research either on place naming in the Falklands within the framework of critical toponomatics or on
ethnography regarding Islanders’ language attitudes. This is a preliminary attempt to do so, by looking into the Spanish place names used in
Argentinian maps but not in local ones. In our analysis, we further resort to in situ interviews, participant observation, and social media
data. Our analysis suggests that these Argentinian toponyms receive neither official nor societal approval by Islanders. We conclude that
Argentinian Spanish names became a point of contention because of the political conflict, leading to a linguistic conflict scenario.
Variable index placement in Gutob from a typological perspective
Authors: Just Erika , Voß Judith 
Published: January 2023

Abstract
In Gutob (Munda, India) S/A indexes can attach to other hosts apart from the verb, unconstrained by syntax. Previous studies have described non-verbal index placement in Gutob as exceptional, establishing verbal indexes as the default. This paper presents the first case study on the placement of Gutob indexes based on corpus data. Our analysis shows that although index placement in Gutob is in fact conditioned by discourse effects, non-verbal clitics cannot be considered particularly exceptional. They are employed to allocate attention to constituents and express engagement with a particular piece of information. In other languages where index placement is similarly flexible, it has been ascribed to the host being in focus. However, we argue although the effects of index placement in Gutob might pertain to what is usually subsumed under this category, other effects like newness, quantification, requested information or negation are not necessarily associated with index placement in Gutob.

Supervised learning approaches to modeling pedestal density
Authors: Kit A , Järvinen A E , Frassinetti L , Wiesen S 
Published: January 2023

Abstract
Pedestals are the key to conventional high performance plasma scenarios in tokamaks. However, high fidelity simulations of pedestal plasmas are extremely challenging due to the multiple physical processes and scales that are encompassed by tokamak pedestals. The leading paradigm for predicting the pedestal top pressure is encompassed by EPED-like models. However, EPED does not predict the pedestal top density,

by about 23% relative to that obtained with log-linear scaling laws, measured by root mean square error. Including all of the available tokamak machine control parameters, both numerical and categorical, leads to further improvement of about 13%. Finally, predictive quality was tested when including global normalized plasma pressure and effective charge state as inputs, as these parameters are known to impact pedestals. Surprisingly, these parameters lead to only a few percent further improvement of the predictive quality.

Authors: Zlateva P , Mileva N 
Published: January 2023

Abstract
The article considers and analyses the opportunities for introducing installations for using energy from renewable sources (RS) in Bulgaria. The aim is, through an analysis of the newly built installations, to point out the benefits from the production of energy from RS, obtained by fulfilling the objectives of the requirements of the European Union (EU) directives for the EU member states and the national strategy for energy independence of Bulgaria. It has been ascertained that in 2020, according to the European Directive 2009/28/EU, Bulgaria had to achieve a 16% share of energy from renewable sources in the gross final consumption, which it exceeded by 7.32%, achieving 23.32%. It has also been ascertained that the share of renewable energy in the structure of primary energy in Bulgaria is 23.8%. In 2020, Bulgaria has a share of energy from renewable sources in the gross final energy consumption of 23.32%, which exceeds the mandatory national target by 7.32%. In 2020, Bulgaria achieved an installed capacity of 5 224.7 MW and the gross production of electric energy increased to 4 627.4 GWh, which was more than twice compared to 2009. For the achievement of these capacities, the newly built local installations also contributed in the production of energy from RS for the period 2017-2021 by planning regions in Bulgaria.

Published: January 2023

Abstract
Thermal waste treatment plants are an answer to the important problem of waste neutralization on the one hand, while inspiring various emotions in society due to their impact on their planned or existing sites on the other. The primary benefit from incinerating waste is the ability to reuse it as fuel to produce energy. The paper presents thermal calculations that present the performance of the entire thermal waste treatment plant, which depends on the final use of the energy it produces. The equations developed make it possible to monitor the energy flow rate in the various components of the power unit, taking into account losses in the boiler and turbine condenser.

Published: January 2023

Abstract
Reducing energy consumption and CO2 footprint in existing buildings without requiring extensive construction work is one of the biggest challenges facing the globe today. Although heating contributes for the majority of energy use in buildings, residential hot water demand is also relatively high, particularly when daily usage is high and especially for certain applications. The use of technologies that recover energy from sources other than fossil fuels to heat water has grown crucial, and one such technology involves recovering thermal energy from wastewater. Typically, heat recovery from wastewater is made to collect any remaining energy from the hot drainage water, and this energy is then applied to heat pumps or to warm up incoming cold water. The paper presents numerical simulations using a SST k-ω turbulence model in order to compare a regular geometry of heat exchanger with a helicoidal one. The second one provides a more turbulent flow that allows an intensification of the outer flow, thus allowing the enhancement of the heat transfer from the inner heated flow to the outer flow.

Authors: Mitov A , Slavov Ts , Kralev J , Angelov Il 
Published: January 2023

Abstract
The article present design, optimal tuning and experimental investigation of a multivariable PID controller intended for variable displacement axial-piston pump. The pump is designed for open circuit hydraulic drive systems. The regulation of the displacement volume of the pump is carried out through a proportional spool valve intended for its model. Unlike classic systems in which the valve receives control electrical signals from an analogue electronic amplifier, in this system the proportional valve receives a control signal generated by a specially developed embedded PID control system. The controller is designed on the base of a model obtained by means of system identification. The set of the controller is performed through an optimization procedure based on a genetic algorithm. Experimental studies were carried out with the designed controller on a laboratory test rig. А comparison between the experimental and simulation results is done.
Energy parameters assessment, under scale effect calculation of centrifugal fans with radial blades
Authors: Stanilov Alexander , Ivanov Martin 
Published: January 2023

Abstract
The centrifugal fans with radial blades are used in various industrial energy systems, associated with high dustiness, due to their self-cleaning ability and their reliable operation. Radial fans are used in cement, asphalt industries and various dust collection facilities. The uniqueness of the different working environment and the specifics of each system require the use of a fan, designed for the particular application. Due to the dimensions of the machines, before the fan is produced, it normally goes through model tests. In model studies of rotodynamic fluid machines, differences are sought between the expected parameters from the application of the similarity theory and the obtained energy parameters. These differences are commonly referred to as the scale effect. Estimating the scale effect in model tests leads to the use of energy efficient machines for a given system. These are the one, that give the desired system parameters when operating in the region of maximum efficiency. Thus, the purpose of modeling is to transfer the efficiency obtained for a given mode of operation of the model machine to the prototype. The operation in the optimal mode of the prototype fan leads to energy savings and a reduction in energy costs for a given technological system. In the presented paper are evaluated the differences between expected and obtained parameters that help to realize a model for a centrifugal fan with radial blades. The results of model tests, conducted on two geometrically similar centrifugal fans with radial blades, where the inlet and outlet angles of the impeller are the same (β1=β2=900
), are given. The fan impellers are semi-open type with 12 blades. Each of the impellers is tested in a geometrically similar helical chamber. Model tests have been conducted on a laboratory test-bench, meeting the requirements of AMCA 210 or ISO5801. The test-bench is equipped with the complete measuring equipment, according to the standards used. During the model tests, both the energy parameters of the fans and the parameters of the surrounding environment are measured. The results of the energy tests of the fans are given in the paper, as well as the coefficients concerning the scale effect are determined and analyzed.

Authors: Pitchurov George T , Markov Detelin , Georgiev Emanuil 
Published: January 2023

Abstract
The capacity to cool the lubrication oil of hydraulic turbine bearings by submerged water heat exchangers has been verified. Calculations are done for existing heat exchangers and for retrofit ones. Input data from on-site measurements was used, as well as data for the physical constants. The goal of the study was to prove that the new heat exchangers’ efficiency is not less than that of the existing heat exchangers. The method of analysis elaborated on calculation of convective heat transfer coefficient. This was done for both a forced convection and an inhibited convection setup. It was debated that only the forced convection setup was a factor affecting the difference between both designs.

Authors: Dimova G T 
Published: January 2023

Abstract
In the 20s of the twenty-first century many nuclear power plants around the world have reached the final years of their design lifetime. The technical aspects of Plant Life Extension (PLEX) activities involve tests, in addition to the routinely performed ones, of the materials and structures of reactor units, as well as the carrying out operability analyses. In relation to this, the absence of regulatory and methodological basis becomes apparent, in Bulgaria as well. In recent years, new approaches have been adopted for evaluation of lifetime characteristics of components. The algorithm implemented is based on the active mechanism of degradation of the mechanical properties of materials. This paper discusses PLEX stages and corresponding activities. A methodology has been developed to assess the lifetime characteristics of Nuclear Power Plant (NPP) components such as to suit the stages of plant life extension and long-term operation. The methodology consists of: 1) Equipment classification; 2) Identification of the major degradation mechanisms of the mechanical properties of materials; 3) Determining the degradation effects of the mechanical properties of materials; 4) Identification of methods to control degradation effects (ageing); 5) Development of methodologies for evaluation of the ageing effects.
Influence of temperature of return district water on the performance of a backpressure steam turbine installation
Authors: Hristov Kaloyan , Genovski Ivan 
Published: January 2023

Abstract
The district heating systems supply heat to a wide range of consumers. In the heat source of such systems, highly efficient technologies are used for the combined production of electrical and thermal energy mainly based on steam turbine installations with backpressure turbines or turbines with adjustable steam extractions. Combined production leads to a reduction in fuel consumption (fuel saving) compared to the separate production of the two energy products. The fuel saving resulting from cogeneration reduces carbon dioxide emissions. Combined production affects the amount of fuel saved, leading to a reduction in emitted emissions, both the size of the heat load realize to consumers and the temperature of the water that enters from the return pipeline of the district heating systems into the heat source. In backpressure steam turbine installations, the district water is heated by the steam that enters the boiler-condenser, and in steam turbine installations with adjustable steam extraction, it is heated in a district heater by steam extracted from the turbine. The purpose of this paper is to study the influence of the temperature of return district heating water on the performance of a backpressure steam turbine installation for cogeneration.

Published: January 2023

Abstract
The concept of neighbourhood planning has emerged as a new trend in our community and the emphasis has been of utmost importance on districts in cities as the basic independent units of metropolitans in a way similar to that of community formation. Improving neighbourhood structure can improve the standards of living through the introduction of a smart neighbourhood model, making it more suitable for being walked and enhancing the life quality of residents that leading to the upgrading of communal and territory sketch. This work focuses on the problems where neighbourhoods lack aspects that allow the use of technology and affect workable distance and social relations, which are the main pillars of liveability. The hypothesis was to evaluate the neighbourhoods constructed by Najaf Investment Commission, whether the standards for the neighbourhood were applied according to the standards of the United Nations Organization (UN-Habitat) using gap analysis, The study found a gap between the standards adopted in the planning and design of the studied residential complexes (Al Ghadeer Residential Complex) and the criteria and indicators for planning smart neighbourhood model, particularly in the effectiveness of traffic network and the occupied residential area which was greater than the commercial model and less than the specified standards.

Authors: Al-Ameedee Raghad Mahdi Muoslim , Rashid Abdul Sahib Naji 
Published: January 2023

Abstract
This research included some concepts of historical areas that were exposed to the concepts of sustainable development to deal with historical areas, to derive from them the benefit that we are trying to apply to historical areas in our Iraqi cities. By reviewing the concepts of sustainable development in the field of historical areas, we find alternative solutions or policies that have already been applied, and they aim to develop historical areas, especially those located in city centres and also aim to achieve various concepts of urban and environmental development in these areas (such as preservation, restoration and rehabilitation). This is in addition to realizing the concepts of economic and social development (such as Al-Aziz, social cohesion, economic growth, and others). Accordingly, the research problem is the lack of knowledge regarding the application of the concepts of sustainability in projects and programs for historical areas locally. While the hypothesis was that sustainable development provides the basic capabilities to solve projects and programs for historical areas that have been exposed to the concepts of sustainability to deal with them for some experiences through which we can benefit and try to apply them in our cities and line with the Iraqi nature. The research aims to review some of the Arab and international experiences of dealing with historical areas in light of the concepts of sustainability. The methodology was following the functional, analytical approach to know the most important indicators related to reaching the objectives of the research. The research found that the best mechanisms or policies in dealing with historical areas are those that deal with the concepts of urban sustainability. It was found through sustainable global experiences that the most important results are the general planning of sustainable development projects, the financing needed to complete sustainable projects, the role of popular participation in this project, institutional thought factors to complete sustainable environmental projects, technical and urban factors necessary for these projects, and the most important tools used in the research is a descriptive analysis by analysing the results of sustainable global experiences.
