AbstractA Scalable Low Voltage Signaling (SLVS) transmitter and receiver have been developed as IP blocks in a 28 nm standard CMOS technology for the future upgrades for the high luminosity LHC. At the target data rate of 1.28 Gbps, the transmitter consumes 6 mW and the receiver consumes 2 mW. The transmitter’s output is powered with 1.2 V to provide compatibility with previous designs, while the core logic can be powered with 0.8 V to reduce power consumption. This work summarizes the design approach at the schematic and layout level. Practical aspects of the novel technology for the design of ASICs in High Energy Physics will be discussed along with characterization results. Other IP blocks are being designed (ADC, DAC, PLL) and they will be presented.

Authors: Atanasov Tomislav 
Published: January 2023

Abstract
The most widely used domestic water heaters in Bulgaria are the electric ones, with a storage tank. The main construction factors for the efficiency of the hot water boiler are considered in the present study: the temperature of water and the volume of the tank; the dimensions of the tank; the time for heating and discharge time; the insulation material and the thickness of insulation; the power of the electric heater. The average volume temperatures have been calculated analytical, the stratification effect is not taken into account. The different variants for design, insulation and the power of heater have been proposed. The results indicate for a possibility of reducing electricity for preparing hot water up to 13%. The further evaluation of the economic capability of the options has to be made.

Experimental analysis of cross-flow wind turbine with omni-directional multi-nozzle
Authors: Iliev R 
Published: January 2023

Abstract
Using guiding devices is a method for increasing the efficiency of vertical wind turbines. The main problem of these devices is the hydraulic losses that occur from shading the turbine runner. Тhe geometry of the guide apparatus must ensure independence from the wind direction and allow free passage of the airflow through the blade cascade of the runner. This paper presents the results of a physical and numerical study of a cross-flow vertical wind turbine with an omni-directional guiding multi-nozzle. The task of the study is to determine the influence of the multi-nozzle on the efficiency of the turbine when the airflow changes its direction. The idea is inspired by the kinematics of the flow through the guide nozzle and runner of the cross-flow water turbine. The experiments were conducted in the Laboratory of Hydro Power and Hydraulic Turbomachinery (HEHT Lab) at the Technical University of Sofia. The obtained results are showing the influence of the multi-nozzle on the performance of the cross-flow wind turbine. They favour the selection of a suitable omni-directinoal guiding device for vertical axis wind turbines.

Abstract
The prediction of integral parameters in the nuclear installations (fluence, activities, doses, etc.) requires a reliable theoretical modelling. The modelling includes the used transport codes themselves as well as reliable nuclear data such as microscopic nuclear parameters, cross sections, covariance matrices, etc. To verify the performed calculations, suitable experiments are used. On the other hand, one may use the theoretical modelling in order to evaluate the most suitable setup for performing a reliable experiment. This is of distinct importance when neutron activation is in place, since the neutron flux, angle of excitation and energy here is of particular importance. Using preliminary modelling the of response function in the activated materials a lot of time and capacity can be saved during the experimental process. This is of particular importance when investigate the 93mNb isotope since it has important properties in the state-of-the-art activity measurement techniques investigations, due to its low-energy gamma lines and its high level of masking due to other elements, and especially the tantalum. Niobium and tantalum are chemical “twins” of the vanadium triad of the periodic table and are notoriously difficult to separate from one another and from their naturally occurring ores, due to their near-identical physical and chemical properties. That is why 93mNb is suitable for a test element in the development of principally new approaches in the radiochemistry. The neutron source definition for Monte Carlo calculations for Nb, Fe and Cu foils activation is described in the paper. The reactor neutron source geometry model is presented. Results for the neutron fluence for activation of the investigated elements are obtained in radial and axial directions of the experimental setup area. Suitable positions for the placement of the investigated elements are selected. The obtained results provide a reliable basis for performing neutron activation experiments for technogenic radionuclides important for man and environment.

Abstract
The paper presents research on the application of vat dyes to inherently flame resistant fabrics, using the conventional screen-printing method. The composition of the fabrics are defined within a scope of a project conducted in partnership of Croatian textile factory Cateks d.d. and University of Zagreb Faculty of Textile Technology. Fabrics are screen printed by using a vat dye Indanthren® Olive R (DyeStar, Germany) in two concentrations. After printing, a coloristic analysis of the obtained colouration is performed, based on instrumental spectrophotometric measurement and objective evaluation of the colouristic parameters (L*, C*, h°) and colour depth (K/S). The samples are tested for resistance to surface burning, and the colour fastness to dry/wet rubbing and light exposure are also tested. Excellent results of fire resistance and dry/wet rubbing resistance are achieved, while resistance to light exposure is lower to optimal.

Abstract
The agricultural sector is one of the most important sectors in Iraq, as it supports the Iraqi economy and provides food security for people in Baghdad. Nevertheless, this sector is suffering from a remarkable decrease in agricultural production. Therefore, there is a high need for the assessment of the agricultural cover in the last decades to provide a comprehensive view of the changes in this sector. The research focuses on the spatial analysis of spatial and urban cover using GIS, remote sensing data, and the NDVI indicator in three periods of time (2001, 2011, and 2021). The results of the study showed a decrease in the area of vegetation cover for the year 2011 for most of the counties while the area of vegetation cover increased in the study area in 2021 in comparison with 2011 due to the impact of the water resources factor and the share of each county. In 2001, the percentage of vegetation cover was 37% of the study area while it was 23% in 2011 and increased to 32% in 2021. This research supports the decision-makers and planners by providing the amount and spatial distribution of the vegetation cover.

Abstract
The expansions of cities and continuous urbanization have prepared comprehensive urban plans necessary. The important thing about these plans is to determine their success, efficiency, and feasibility. The expansion of the city comes because of the population increase or investment. When the expansion of cities precedes the updating of its master plans and the development of alternative plans to accommodate these expansions, it is normal that finds irregularities in use and differences between the master plan and real land use. Therefore, the main purpose of this paper is to examine the extent of illegal changes in the current situation in comparison with master plans. Also, the efficiency of artificial neural network models is evaluated to predict illegal land-use changes. The old master plan (1990-2010) and the new one (2010-2030) was used with two high-resolution satellite images dated 2010 and 2018. To determine changes between the status quo and the uses defined in the master plan, the required information tables were completed by field visit with questioner made for Al-hay City. Neural network models were used to evaluate the survey, data was divided into two parts training and testing then a neural network model was performed on them after testing the results using the neural network model, the results present that the accuracy of about 85% for the old master plan and pass 91% for the updated master plan. The largest percentage of differences between the real use and master plan for the year 2010 was in (Religious use, Parking, Gas stations, then government use, green areas, educational use, and residential), but note that the largest percentage of differences between the real use and master plan for the year 2018 were in (Religious use, Athletic use, Green areas, then commercial and governmental uses).

Published: January 2023

Abstract
The modern industrial projects and complexes that adopt ecological systems, and renewable, clean and environmentally friendly energy, not only contribute to the development of an environmentally friendly production method but can achieve long-term economic and industrial development by preserving environmental resources. The ecological industrial systems and modern industrial technologies are the ideal solutions to rationalize excessive use and preserve the elements of the environment and natural resources, the most important of which is the existence of several methods and programs for the development of industrial sites, and there is important to adopt mechanisms and programs to solve the problems of traditional industries to reach industrial techniques characterized by rationalization, reduction in the depletion of natural resources, the most important of which is the triple system (reduction, recycling, and reuse of industrial waste) and other eco-systems. By applying the indicators to the study area in the new industrial city in Ramady, it was found that there is a weakness in the application of the indicators and did not achieve the required level. It becomes clear to us the need to take into account the activation of these indicators to reach the achievement within the industrial city.
