Opis:
W artykule przedstawiono wyniki analiz różnic w wydajności opieki zdrowotnej świadczonej w szpitalach zlokalizowanych w zachodnich i południowych regionach Ukrainy. Oszacowano poziom wydajności przy użyciu techniki modelowania nieparametrycznego –metody DEA. Metoda ta stanowi narzędzie stosowane do porównań i oceny względnej skuteczności kilku jednostek gospodarczych będących jednostkami decyzyjnymi (DMU). W badaniu skupiono uwagę na różnicach w poziomie efektywności szpitali.
This study examines variations in efficiency among hospitals located in western and southern Ukraine. We estimated efficiency using a nonparemetric modeling technique known as data envelopment analysis (DEA). DEA is a very powerful tool to compare relative efficiency among several economic units of study, known as decision making units (DMUS). In our current and previous research we have focused attention on comparative efficiency among hospitals and then explained variation in efficiency based on historical and cultural differences that influence managerial behavior at the hospital level of decision making. This study using current data and an expanded geographic territory provides further support to our findings from previous studies.

Opis:
The article gives results of the development of the system of monitoring for photovoltaic power installations with different configuration to study the factors, increasing their productivity. Differentiation of impact, made by the components of different structure of photovoltaic power installations is made by application of three independent controlled channels of energy extraction from photovoltaic panels: fixed focused, with application of solar tracker and with application of solar tracker, having flat mirror concentrators. To secure originality of the record of the electric energy, produced by photovoltaic panels, we have developed unit of control for discharging current of battery banks in each channel. It supports equal level of their charge. Amount of the produced electric energy in each channel is estimated by the value of discharge. Control and measuring system is made on the base of virtual devices with hardware unit of input/output of NI USB-6009 type, produced by National Instruments Company, with software LabVIEW. In the research, software code of the system of monitoring and front panel of operator have been developed. The work provides photos of the developed experimental stand.

Opis:
The main subject of theoretical-empirical study presented in this paper is economic efficiency of companies listed on the Polish and German capital market. The discussed research problem was investigated in the form of a comparative analysis and realized in two parts. The discussion presented in the first part depicts mainly theoretical reflections on the essence and assessment measures of companies’ economic efficiency. The second part presents the results of a comparative empirical research on economic efficiency of the companies listed on the Warsaw Stock Exchange and included in the WIG30 index as well as the companies listed on the Frankfurt Stock Exchange, which belong to the DAX index. The research period comprises years between 2004-2013. A comparative analysis of economic efficiency of the companies was conducted using a traditional ratio analysis and the nonparametric DEA method. The results of the empirical research confirm that German companies achieved significantly higher values of basic economic categories in the analysed decade, financial results in particular; however, their generated profits did not reflect in higher values of profitability ratios. Polish companies performed much better as they also showed higher efficiency from the DEA’s point of view.

Opis:
Cryptocurrencies have become an important element of the global financial system and a frequent investment tool in the last decade. The aim of this paper is to compare the efficiency of investments in the cryptocurrency market with investments in global capital markets. The study used the quotations of the analyzed instruments in the years 2011-2020. The investment efficiency was estimated using Sharpe and Sortino ratios. Research has shown that investments in cryptocurrencies were the most effective. They brought, on average, the highest daily rates of return, but on the other hand, they were characterized by the highest risk. Such a result could have been significantly influenced by the widespread persistence of ultra-low interest rates and a decline in the attractiveness of debt securities. The best results were obtained for investments in bitcoin and ethereum, which have the largest share of cryptocurrency market capitalization.
Kryptowaluty, stanowiąc niezależny system, stały się w ostatnim dziesięcioleciu istotnym elementem globalnego systemu finansowego i częstym narzędziem inwestycyjnym.  W pracy porównano poziomy efektywności inwestycji na rynku kryptowalut z inwestycjami na globalnych rynkach kapitałowych. W badaniu wykorzystano notowania analizowanych instrumentów w latach 2011-2020. Efektywność inwestycji oszacowano przy użyciu wskaźników Sharpe’a i Sortino. Badania wykazały, że, średnio w całym okresie badanym, inwestycje w kryptowaluty charakteryzowały się najwyższym ryzykiem ale i najwyższymi dziennymi stopami zwrotu. Sprawiło to, że były one najbardziej efektywne. Na taki wynik mogło mieć istotny wpływ powszechne utrzymywanie się ultra niskich stóp procentowych i obniżenie atrakcyjności w dłużne papiery wartościowe. Najlepsze wyniki stwierdzono dla inwestycji w bitcoina i ethereum posiadające największe udziały w kapitalizacji rynku kryptowalut.

Opis:
Aim:The objective of this paper is to make comparative analysis on operational efficiency between Chinese and Indian commercial banks (CBs).   Design / Research methods: Following the previous scholars’ study, two models with different sets of input and output variables have been used to show how efficiency scores vary with change in inputs and outputs. The efficiency scores are measured by using data envelopment analysis (DEA) approach.   Conclusions / findings: The mean technical efficiency score of Chinese CBs is always relatively higher than the corresponding score of Indian CBs in 2012-2013, respectively. In terms of technical efficiency and pure technical efficiency, the performance of foreign banks in China is always relatively lower than that of foreign banks in India.   Originality / value of the article: While many similar studies have evaluated the performance of banking industries in different countries, very few studies have evaluated the performance of banking sectors between Chinese and Indian economies. The paper would be of interest for OR scholars and practitioners in financial industry.  Implications of the research (if applicable): The next step of this study could collect more samples and use Malmquist index method to conduct further study on efficiency, efficiency changing and productivity, in order to conduct further competitive power analysis on both of banking industries of China and India.

Opis:
The escalating prevalence of rooftop solar PVs and DC powered home appliances are the driving forces for the research in the field of DC distribution at residential level. The current research work presents comparative analyses of AC and DC distribution systems considering various scenarios for the specific purpose of efficiency/energy savings. A modern Bakersfield CA, USA home is considered for the analyses. The loads are classified according to the power demand. Rooftop solar PVs are also included in each residential building. Mathematical equations are devised for the efficiency analysis of residential buildings powered with AC as well as DC. The results reveal strong dependence of the efficiency values on the utilization/types of loads, efficiencies of the power electronic converters (PECs), solar capacity and seasonal conditions, as a function of the time of day. It is concluded that AC system presents better efficiency values as compared to the DC counterpart except during the time periods when solar power is available and when the penetration of variable speed drive (VSD) based loads is high.

Opis:
The paper presents a comparative analysis of the results of radial drilling, drilling perforation, cumulative reperforation and acid treatment. The study was focused at carbonate deposits in Russia. For each technology average incremental oil rates were estimated at the same exploration targets. The analysis of technological effectiveness in the given geologic and physical conditions revealed that drilling perforation and radial drilling allow reaching higher incremental oil rates compared to acid treatment and cumulative perforation. This fact confirms effectiveness of drilling radial canals by enlarging infiltration area. For the sake of completion radial drilling and drilling perforation are performed in the same wells. To reveal limiting conditions of applying radial drilling and drilling perforation an effectiveness analysis is made depending on the thickness of the interlayers exposed. To formulate criteria of radial exposing applicability an analysis of effects of different geological and physical formation parameters on geological and engineering operations effectiveness is done. The following parameters are considered: relation between the current formation pressure and initial formation pressure, formation permeability, skin factor, thickness of interlayers in overall perforation interval, thickness of interlayers exposed by radial canals.

Opis:
The article describes a hybrid approach to evaluating economic efficiency of medium-sized manufacturing enterprises (employing from 50 to 249 people) in districts of Wielkopolska province, using metric and interval-valued data. The hybrid approach combines multidimensional scaling with linear ordering. In the first step, multidimensional scaling is applied to obtain a visual representation of objects in a two-dimensional space. In the next step, a set of objects is ordered linearly based on the distance from the pattern (ideal) object. This approach provides new possibilities for interpreting linearly ordered results of a set of objects. Interval-valued variables characterise the objects of interests more accurately than metric data do. Metric data are atomic, i.e. an observation of each variable is expressed as a single real number. In contrast, an observation of each interval-valued variable is expressed as an interval. The analysis was based on data prepared in a two-stage process. First, a data set of observations was obtained for metric variables describing economic efficiency of medium-sized manufacturing enterprises. These unit-level data were aggregated at district level (LAU 1) and turned into two types of data: metric and interval-valued data. In the analysis of interval-valued data, two approaches are used: symbolic-to-classic, symbolic-to-symbolic. The article describes a comparative analysis of results of the assessment of economic efficiency based on metric and interval-valued data (the results of two approaches). The calculations were made with scripts prepared in the R environment.

Opis:
In the current discussions on the future of the automotive industry, two extreme opinions clash: electromobility or vehicles with conventional drive but powered by alternative fuels. The article discusses the issue related to modeling the energy efficiency factors of a combustion engine operating on three types of fuels (Diesel 100%, Biofuel 100%, and Hemp Oil 100%) as well as an electric drive powered by energy from a coal power plant. Analytical research was conducted based on the external characteristics of the engine's performance. The external characteristic of the Fiat Panda 1.3 JTD combustion engine was obtained on the Automex dynamometer. The engine operated on three fuels: Diesel 100%, Biofuel 100% (rapeseed), and Biofuel 100% (hemp oil). The Nissan Leaf vehicle manufacturer provided the external characteristics of the electric engine. The calculation results showed that the combustion engine consumes less energy at lower speeds than the electric one. At higher speeds, the consumption rates are at a similar level. The recipients of the research are both the demand side – that is, vehicle users, as well as future manufacturers and government institutions responsible for shaping and developing future mobility in the field of individual transport.
W toczących się obecnie dyskusjach na temat przyszłości motoryzacji ścierają się dwie skrajne opinie: elektromobilność lub pojazdy z konwencjonalnym napędem, ale zasilane paliwami alternatywnymi. W artykule omówiono zagadnienie związane z modelowaniem współczynników efektywności energetycznej silnika spalinowego zasilanego trzema rodzajami paliw (olej napędowy 100%, biopaliwo 100% i olej konopny 100%) oraz napędu elektrycznego zasilanego energią z elektrowni węglowej. Badania analityczne przeprowadzono w oparciu o zewnętrzną charakterystykę pracy silnika. Charakterystykę zewnętrzną silnika spalinowego Fiat Panda 1.3 JTD uzyskano na hamowni Automex. Silnik pracował na trzech paliwach: olej napędowy 100%, biopaliwo 100% (rzepak) oraz biopaliwo 100% (olej konopny). Zewnętrzna charakterystyka silnika elektrycznego została dostarczona przez producenta pojazdu Nissan Leaf. Wyniki obliczeń wykazały, że przy niższych prędkościach silnik spalinowy zużywa mniej energii niż silnik elektryczny. Przy wyższych prędkościach wskaźniki zużycia są na podobnym poziomie. Odbiorcami badań jest zarówno strona popytowa - czyli użytkownicy pojazdów, jak i przyszli producenci oraz instytucje rządowe odpowiedzialne za kształtowanie i rozwój przyszłej mobilności w zakresie transportu indywidualnego.

Opis:
The birth of electricity witnessed “the battle of currents” between AC and DC as a medium of power transfer. AC won the battle in the first place because of its ability to transform voltage levels. However, with the development of power electronic converters (PECs), DC is striking back. Most of the electronic loads in our conventional AC-based homes are DC by nature. Moreover, the modern concept of energy-efficient variable speed drive (VSD) based loads, i.e. DC-inverter based air-conditioners and refrigerators, require a DC link for their operation. The driving component of all such loads is the PEC. The operational efficiency of PECs depends on the loading which varies throughout the day. This paper presents a mathematical model based on a bottom-up approach to the comparative efficiency analysis of AC and DC distribution systems considering daily load variation. Two topologies are presented where AC and DC distribution systems are compared in terms of efficiency. The first topology (T1) defines a separate/independent converter for each load, whereas in the second topology (T2) loads of a particular class are lumped and driven by a single converter. The results present DC distribution better than AC distribution with an efficiency advantage of 2.28% and 1.57% for T1 and T2, respectively.

This article describes the construction and principles of operation of a prototype energy-converting machine – a flow machine with pistons rotating in toroidal spaces. A comparative analysis of the results of simulation and experimental tests of fluid flow resistance in the presented prototype machine has been performed with the use of correlation and integral calculi. The article also presents a comparative analysis of the volumetric efficiency of the examined pump and of a Vogelsang pump with similar design and size. The present state of the research makes it possible draw conclusions about the high exploitation value of the proposed pump construction. For this displacement pump, performance increases along with rotational speed. However, it is different from other pumps by virtue of is simple and compact construction as well as greater capacity in relation to its size.

Opis:
Purpose: Comparative analysis of human capital and its efficiency in enterprises with various business profiles, especially the so-called old and new economy. Design/methodology/approach: The analysis was carried out on the example of companies listed on the Warsaw Stock Exchange operating in the industrial and high-technology sectors. For its purposes, indicators based on financial data and used, among others in the method of assessing the efficiency of intellectual capital - VAIC. Findings: The obtained results allow to conclude that the situation in terms of human capital level and its efficiency, including labour efficiency, in the analysed enterprises is highly diversified. These differences not only exist between companies from different sectors, but also within individual sectors, industrial as well as high-tech. Companies from high-tech sectors are generally characterized by a higher human capital level, as well as its efficiency, which is particularly distinguished by the sector Video Games Developers. Research limitations/implications: Due to the limited quantitative research sample, compared to the total number of companies listed on the Warsaw Stock Exchange and the industries and sectors they represent, the results obtained and the conclusions drawn on their basis can be treated as preliminary and contributing to further broader research. Practical implications: As the results of the analysis show how individual industrial and high technology companies compare to the competition in terms of the level and efficiency of human capital, it may be an indication for their management boards of the need for actions aimed at improving the efficiency of human capital. Social implications: As the subject of the analysis is human capital in an enterprise, its results may contribute to changes in the field of corporate social responsibility in the analysed enterprises in the area of employees. Originality/value: The topic of the article is not new, but in the literature there are hardly any studies on the assessment of the efficiency of human capital in the intersectoral approach.
