Published: April 2017

In recent years, due to the growth of petroleum prices  and  gas  emissions,  the  renewable  energies  have  been recommended like feed sources to different types of facilities,and therefore, since 2010 to 2020 the European Commission has established three key objectives related with climatic change and the energy sustainability like are reduction of the CO2 emissions, increase of the use of the renewable energies and the rise of the energy efficiency. A key sector are the produce installations of olive  oil  also  called  “olive  mills”,  where  there  is  a  great opportunity  to  reduce  the  electrical  consumption,  increase  the additional profits related to reduction of harmful technologies to the environment and reduce the costs in its maintenance. For this reason, this paper investigates and compares the technical and environmental feasibility of olive mills, powered by renewable sources such as; solar energy, wind energy, biomass energy or combination of them in Andalusia (South of Spain), having this region a huge energy dependency, but large amount of “green” resources to be used.
The feasibility of these systems will be carried out taking into account  the  cost,  power  generation,  CO2  equivalent  emissions and fraction of renewable energy, assuming that they are grid-connected.

Authors: Ji-Hyun Mun  , Dong-Soon Jeon  , Seon-Chang Kim  , Young-Lyoul Kim
Published: April 2017

This paper presents a study of the regeneration performance characteristics of an internally heated regenerator applicable to a liquid desiccant system. The internally heated regenerator used in this study was designed and manufactured to provide good regeneration performance. An experimental setup was established to test the regeneration performance. LiCl aqueous solution was used as working fluid. Variables to evaluate regeneration performance characteristics of the internally heated regenerator were dry bulb temperature, relative humidity and velocity of regeneration air, mass flow rate, temperature and concentration of the LiCl aqueous solution. The experimental conditions were chosen by using a 1/2 fractional factorial DOE. Regeneration rate and regeneration effectiveness were taken as results. From the results, solution concentration and regeneration air relative humidity have strong effects on the regeneration rate. The regeneration effectiveness was affected mostly by regeneration air velocity and LiCl aqueous solution temperature.

Authors: N. Ell  , D. Turschner  , M. Stubbe  , H.-P. Beck
Published: April 2017

In this paper a method to estimate the drive torquesfrom Light Detection  and  Ranging  (LiDAR)  measurements  is proposed. Knowledge of these values brings many advantages for turbine  control  and  especially  active  damping  of  mechanical  oscillations.
Primarly a simplified method to calculate the aerodynamic torquefrom  wind  speed  measurements  of  a  nacelle  based  LiDAR-system will be presented which bases on  blade element momen-tum  theory  (BEM). Comparisons  of  results  of  the  original  and  a simplified  computation  method  show  small  deviations  in  the  relevant working range of a wind turbine. Additionally a Kalman Filter is used to estimate the drive torques   of the wind turbine.  
The method is tested in simulation using a model of a doubly fed induction  generator  (DFIG)  wind  turbine  including  a  gearbox.  Simulation results show good performance of the estimation.

Authors: S. Müller  , J. Meyer  , P. Schegner  , S. Djokic
Published: April 2017

Fully electric cars will be increasingly used in the near future in many countries. They are commonly known as electric vehicles (EVs) and use power electronic-based rectifiers for charging their batteries, which may significantly impact power quality in LV and MV distribution grids. Of particular importance are harmonic emissions of EV chargers, which are strongly influenced by the distortion of the supply voltage. This paper presents the results of testing and analyzing harmonic current emission of eight different single-phase EV chargers, with respect to supply voltage distortion. The analysis is based on extensive measurements performed at a test stand, capable of accurately reproducing supply voltage waveforms with desired distortion. The harmonic model consists of a constant part and a part that depends on the level of harmonics in the supply voltage. In order to characterize each EV charger in a general model, some characteristic indices are introduced, which quantify the sensitivity and linearity of harmonic currents of EV chargers to harmonics present in the supply voltage. The paper presents and discusses results for each individual EV charger, as well as a comparison of them.
Low Drop-Out Voltage Regulator as a Candidate Topology for Photovoltaic Solar Facilities
Authors: Herminio Martínez-García
Published: April 2017

This article aims to present the design of a 4.5-V, 450-mA low drop-out (LDO) voltage linear regulator based on a two-stage cascoded operational transconductance amplifier (OTA) as error amplifier for photovoltaic solar DC-DC regulation. The aforementioned two-stage OTA is designed with cascoded current mirroring technique to boost up the output impedance. The proposed OTA has a DC gain of 101 dB under no load condition. The designed reference voltage included in the LDO regulator is provided by a band gap reference with the temperature coefficient (Tγ) of 0.025 mV/ºC. The proposed LDO regulator has a maximum drop-out voltage of 0.5 V @ 450 mA of load current, and has the worst case power supply rejection ratio (PSRR) of [54.5 dB, 34.3 dB] @ [100 Hz, 10 kHz] in full load condition. All the proposed circuits are designed using a 0.35 µm CMOS technology. The design is checked in order to corroborate its performance for wide range of input voltage, founding that the circuit design works fine meeting all the initial specification requirements.

Authors: G. Vitale
Published: April 2017

This paper proposes the analysis of buck, boost and buck-boost converters by the mean node voltage method to implement them in simulink® environment. The corresponding equivalent linear circuit in the s-domain are determined and the static gain, the audio susceptibility function, the output impedance and the control-to-output transfer functions are deduced accounting for the parasitic effects of inductors and capacitors as well. This approach is simpler compared to the state space averaging method and allows the simulation time to be reduced. The implementation in Simulink environment® of the converters are described and finally the simulated waveforms of a buck converter are compared with the experimental ones.
The position of the maximum erosion points in coal powder pneumatic transport installations, function of the bend radius / pipe diameter ratio
Authors: Dorina Ionescu
Published: April 2017

One major problem of all pneumatic transport installations is the high wear resulting from abrasion at transition sections, especially bends. Using Computational Fluid Dynamics software, by changing the bend radius (BR)/pipe diameter (PD) ratio, the maximum abrasion points, particles velocity and pressure drop were monitored. It was found that as the BR/PD ratio is increased, the erosion and particle velocity values are steadily decreasing. For bends having a BR/PD ratio between 1 and 3. 25 there will be only one maximum erosion point, situated at about 450 from the bend entrance. For a BR/PD ratio between 3.5 and 10.25 there will be two maximum erosion points one at approximately 380 and the other at about 800 from the bend entrance. For a BR/PD ratio between 10.5 and 12 there will be three maximum erosion points one at approximately 300 the second at about 600 and the third one at approximately 830 – 870 from the bend entrance. As the BR/PD ratio increases, the erosion values decrease at a steady rate but the velocity and pressure drop a getting dangerously close to pipe clogging. A balance has to be kept by reaching the lowest erosion rate without clogging the pipes.
Influence of standard sections and time periods on optimization of a distribution network supplied by solar source
Authors: Fergani.S  , Si ali.M  , Flazi.S
Published: April 2017

This paper shows the influence of cables standard sections and time periods on the location of solar energy generator, in order to optimize its distribution network. These parameters can influence considerably the whole cost of installation during the running of a project. An approach of resolution consists of determining the emplacement of the solar generator. For the electrical cables sections with a constant voltage drop, it is then placed in the electrical center of gravity 'E.G.C’ of various loads that surrounds it. However, for cross sections which cover all installation conditions (standard sections), the generator is not in the gravity center (E.G.C), this optimal position (O.G.P) is known as having minimum of copper volume, that mean the least cost of cable for the complete installation. The determined standard sections for each cable, in this positions, are the smallest technically acceptable. An optimal section has been calculated in order to achieve the lowest annual cost of the investment. The obtained results prove that the adoption of this section has an effective economical profit in terms of energy gain.
Interregional R and D spillovers and regional convergence: a spatial econometric evidence from the EU regions
Authors: Furková Andrea , Chocholatá Michaela
Published: May 2017

Research background: Many contemporary empirical studies and also most of economic growth theories recognize the importance of innovation and knowledge for achieving an economic growth. A large part of empirical literature has treated the issue of beta convergence without the spatial aspect, i.e. the possible spatial dependence among regions or states in growth process was neglected.Purpose of the article: In this paper, we investigate the link between selected R and D (Research and Development) indicators as proxies for the regional innovation and knowledge and economic performance of the region. We also assume a significant role of regional R and D spillovers in the regional growth process determination.Methods: The main methodological basis for our analysis is beta convergence approach and the dataset under the consideration consists of 245 NUTS 2 (Nomenclature of Units for Territorial Statistics) EU (European Union) regions during the 2003?2014 period. Our analysis is made with respect to spatial interactions across the EU regions.Findings and Value added: The influence of R and D indicators on the economic growth has been confirmed, and spatial interconnection across the EU regions have been proven. Potential existence of geographical R and D spillovers across the EU regions was examined by formulation of additional beta convergence model with spatial lag variables. We have identified that the influence of R and D spillovers is not strictly restricted to the neighbouring regions, but they spread across a larger area. For the construction of spatial lags of R and D indicators different spatial weight matrices were considered.

Authors: Marszk Adam , Lechman Ewa , Kaur Harleen
Published: May 2017

Research background: Exchange traded funds (ETFs) are one of the most influential financial innovations, reshaping the investment funds market in many countries, including Mexico. Due to their similar investment objectives, ETFs are considered substitutes for mutual funds.Purpose of the article: The aim of the article is to provide an indepth insight into the issues associated with the development of financial markets in Mexico over the period 2002-2012, putting special emphasis on the development patterns of ETFs.Methods: First we use descriptive statistics to unveil basic changes and trends in the Mexican investment funds (ETFs and mutual funds). Then we use a category of the innovation diffusion models, i.e. logistic growth models, in order to explore the key development patterns. Data sources and methodological framework are presented in the second section of the article, with a detailed description of the innovation diffusion models applied in the research (based on 3-parametric logistic curve). The sum of assets under management of ETFs and mutual funds is considered as the size of the total investment funds market.Findings and Value added: Empirical findings indicate a significant development of the ETF market, both in terms of assets under management and market share. According to the presented estimations, Mexican ETF market development can be described with the logistic growth models, and three characteristic phases of the logistic curve were clearly observable. The predicted ETF market development patterns point towards a further increase of the market share of ETFs over the next 3-5 years, yet the probability of exceeding the level of ca. 20-30% seems low.
Estimating inequality aversion from subjective assessments of the just noticeable differences in welfare
Authors: Kot Stanislaw Maciej
Published: May 2017

Research background: In Economics, the concept of inequality aversion corresponds with the concept of risk aversion in the literature on making decision under uncertainty. The risk aversion is estimated on the basis of subjective reactions of people to various lottery prospects. In Economics, however, an efficient method of estimating inequality aversion has not been developed yet.Purpose of the article: The main aim of this paper is to develop the method of estimating inequality aversion.Methods: The method is based on two income thresholds which are subjectively assessed by surveyed respondents. Given the level of household income, just noticeable worsening of household welfare is perceived below the first threshold, whereas just noticeable improvement of household welfare is perceived above the second threshold. The thresholds make possible effective calculations of the parameter of the Arrow-Pratt?s constant inequality aversion utility function. In this way, an individual utility of income becomes an empirically observable economic phenomenon.Findings and Value added: In this paper, two theorems are proved which provide the guidance on how to identify a proper version of the above function. The proposed method is tested on the basis of statistical data from the archival survey conducted among Polish households in 1999. The statistical analysis of those data reveals the appearance of convex utility functions as well as concave ones. Nevertheless, the prevailing part of the Polish society exhibited inequality aversion in the year 1999. Another result of this paper is that inequality aversion diminishes as income increases.
Economics and groups: methodological individualism and collective action
Authors: Ząbkowicz Anna
Published: May 2017

Research background: Paradoxically enough, a large body of contemporary research relies on methodological individualism in order to explain collective activities and decision making. The mainstream of economic theories hardly gives any background to the issue of group activities.Purpose of the article: The aim of this paper is to investigate which economic theories have addressed the problem of collective action, and how social scientists deal with it contemporarily.Methods: Consequently, the research relies on the study of heterodox literature concerned with the subject, referring to original works of most respected authors. The review is carried on systematically, respecting two competing approaches regarding methods and social philosophy.Findings and Value added: Studies on collective action are a domain of institutionalism, the "old" one and the "new" one. Have it both ways, institutionalist studies are rather imperfect in explaining this crucial phenomenon of economic reality.

Authors: Zvarikova Katarina , Spuchlakova Erika , Sopkova Gabriela
Published: May 2017

Research background: It does not matter if the company is operating in the domestic or in the international environment; its failure has serious impact on its environment. Because of this fact it is not surprising that not only owners of the companies, but also another interested groups are focused on the prediction of the company´s financial health.Purpose of the article: The first studies concerned with this issue are dating back to 1930 but from this time a hundreds of bankruptcy prediction models have been constructed all over the world. Some of them are known world-wide and some of them are known only on the national level. Many researchers share their opinion, that it is not appropriate to use foreign models in the domestic conditions non-critically, because they were constructed in the different conditions. One of the main problems are used variables.Methods: We mention three studies which were focused on the used variables in the bankruptcy prediction models. Our comparative study was concerning with 42 models constructed in the seven chosen transit economics with the aim to realize which variables are relevant and which could be reduce from the bankruptcy prediction models. We focused only on the used variables and abstracted from the used methodology, the date of their construction or the model´s power of relevancy.Findings and Value added: The result of our comparative study is the identification of 20 variables, which were used in three or more prediction models, so we assume that these variables have the best prediction ability in the condition of transit economics and their application should be consider in the construction of new models.
The impact of public procurement system on the development of competition in the economy in the light of empirical research
Authors: Borowiec Arkadiusz
Published: May 2017

Research background: The purpose of the public procurement system in the market economy should be to ensure that the public sector entities conduct purchases which are optimal from the economic point of view, as well as to prevent favoring or discrimination of entities participating in public tenders. The Public Procurement Act mentions fair competition as one of the fundamental principles. Both contractors and contracting entities are subject to this principle. In practice, however, it is very often violated in connection with a number of phenomena resulting from imperfections of the aforementioned system.Purpose of the article: The purpose of this article is to identify the most important solutions to support the development of competition in the economy through the public procurement system, as well as to examine the obstacles and risks carried by the system itself. Another purpose is to present further action proposals based on research ? actions affecting the development of competition and at the same time improving the efficiency of tenders.Methods: The article is based on the analysis of literature and on a questionnaire. The survey was conducted electronically (CAWI). The questionnaire was sent to 300 entities required to apply the provisions of the Public Procurement Law throughout the country. Another method involved a direct route (PAPI) and 155 entities participating in public tenders as contractors. Purposeful sampling was implemented to ensure reliable and expert replies. The study was carried out in the first half of 2016.Findings and Value added: The results indicate the most important solutions supporting the development of competition. They include the following: facilitating access to information about orders, improving the efficiency of state authorities in detecting collusive tendering, reducing the possibility of using the potential of third parties, and increasing the availability of data on tender results. The solutions presented in this article are evolutionary rather than revolutionary, and point primarily to the ability to streamline existing procedures and regulations and not to replace them with new ones. They should also help to improve the functioning of public procurement system in Poland, which is of great importance for the development of competition in domestic economy.

Research background: Since January 2013, pension fund management companies have had to establish at least two pension funds, one guaranteed bond fund, and at least one unguaranteed equity fund. This division has brought many changes in portfolios of pension funds in Slovakia. Currently, six pension funds management companies manage six bonds, six equity, five indexed and three mixed funds.Purpose of the article: The aim of this article is to monitor the composition of assets during 2009 and 2014 and describe relation between equity and mixed pension funds? profit and components of assets they own. The results of this research contribute to a better understanding of the importance of certain types of financial assets owned by equity and mixed funds and their impact on pension funds? profit. Last, but not least, this article helps to improve the legislative management of pension funds and their impact on macroeconomic situation in Slovakia, because pension funds are still concentrating higher and higher amount of financial assets from government bonds to companies? stocks.Methods: This relation will be described by linear mixed-effects model with random effects of years and pension funds management companies. Random effects also help to identify the impact of changes during the period studied, and in case that profit is significantly different across the pension funds management companies.Findings and Value added: The underlying model data will be chosen from annual balance sheets, income statements and notes of Slovakia-based equity and mixed funds during the period studied.

Authors: Khotimah Tutik , Syukur Abdul , Soeleman M. Arief
Published: April 2017

Salah satu cara untuk mengetahui beban sebuah trafo distribusi PLN masih memenuhi batas normal atau overload adalah dengan melakukan pengukuran beban trafo tersebut. Pada PLN Area Pelayanan Jaringan Kudus, pengukuran beban dilakukan baik pada siang hari mau pun pada malam hari. Hasil pengukuran tersebut memiliki kemungkinan berbeda. Hal ini disebabkan pada siang hari penggunaan beban cenderung kecil, sedangkan pada malam hari pemakaian beban lebih besar. Hal ini menyebabkan sulitnya menentukan beban trafo tersebut masih normal atau overload. Untuk memetakan beban trafo distribusi secara cepat dan akurat, diperlukan teknik data mining yaitu clustering. Penelitian ini dilakukan dengan menerapkan algoritma Self Organizing Map (SOM). Dengan SOM dihasilkan nilai akurasi sebesar 93% terhadap hasil pengukuran beban trafo distribusi pada siang hari dan sebesar 84% terhadap hasil pengukuran beban trafo distribusi pada malam hari. Sedangkan error yang dihasilkan dari pemetaan dengan SOM sebesar 7% terhadap hasil pengukuran beban trafo distribusi pada siang hari dan sebesar 16% terhadap hasil pengukuran beban trafo distribusi pada malam hari.

The Transformation of Aesthetics in Architecture from Traditional to Modern Architecture: A case study of the Yoruba (southwestern) region of Nigeria
Authors: Arenibafo Femi Emmanuel
Published: May 2017

Aesthetics is the philosophical study of art and natural beauty and it is indicated by the feelings of pleasure or displeasure which comes from visual and aural elements and artefacts. Hence, aesthetics depends on the animate or inanimate organization which can be perceived either subjectively or objectively. This aesthetic element is uniquely present in the traditional buildings and modern buildings of the southwestern part of Nigeria. This study is set out to evaluate and bring into limelight the aesthetic characteristics of traditional buildings and that of the modern buildings, how one style or aesthetic element gradually prevail over or transform to another, reasons and consequences of one completely predominating another in Yoruba region of Nigeria. Moreover, this study therefore, is divided into four parts, which are: (a) overview of the history of modern and traditional Architecture of Yoruba land (b) aesthetic characteristics or indicators of traditional and modern architecture in Yoruba land, (c) the differences between the aesthetic of both styles of Architecture and what is responsible for this change or transformation in their aesthetic value. The research concludes with recommendations of synchronizing both styles of architecture design in getting an optimum aesthetic value and offers a room for further research and development of a consistent and notable architectural typology for southwest Nigeria.
The Influence of Globalization on Distracting Traditional Aesthetic Values in Old Town of Erbil
Authors: Hariry Zhino
Published: May 2017

Aesthetics as a discipline was originally part of philosophy and cosmology, primarily it was used to create a holistic picture of the world. Throughout history, subject and tasks of aesthetics as a discipline have been changing in different historical, cultural, religious and artistic discourses, nature and the beauty of objects intentionally produced by man, but doubts in the division of aesthetic experiences in comparison to these variants of beauty. One of the cities, where started to rebuild in North Iraq after the Saddam Hussein s regime, was Erbil. This fact has evidently started to come out as a problem of urban conservation that results in the loss of architectural and social values of the historical settings. New building in a historical settlement is an urban conservation problem that forms out a methodology of analyzing and evaluating the existing built fabric with a typological study, making an interpretation of it commenting on the legal regulations and introducing new principles that are based on the synthesis of the past and today for providing historical continuity and preserving urban identity despite the continuous change. The study revealed that by using local and traditional elements in modern architecture there is a possibility to protect the historical building.
Rehabilitation 2030: A Call to Action Relevant to Improving Musculoskeletal Health Care Globally
Authors: Briggs Andrew M. , Dreinhöfer Karsten E.
Published: May 2017

The profile of human health is changing across the globe such that the burden of noncommunicable diseases (NCDs), particularly musculoskeletal conditions, is becoming more profound. Such change demands that health systems adapt to better support people in maintaining a functional health state and quality of life, as life expectancy continues to increase. In parallel to the rising burden of NCDs, in particular a disability burden, the need for rehabilitation services is increasing. The World Health Organization (WHO) responded recently with “Rehabilitation 2030: A Call for Action” (February 6–7, 2017, Geneva, Switzerland) and the publication of key recommendations for action. In this editorial, the authors reflect on Rehabilitation 2030 and consider its implications for health system reform in the context of rehabilitation for musculoskeletal health.

Necessity of oral health intervention in schizophrenic patients – A review
Authors: Gupta Swati , PK Pratibha , Gupta Richa
Published: May 2017

Individuals with mental illness often cannot perform day to day activities due to a psychiatric or emotional disorder. Schizophrenia is one such psychiatric disorder characterized by worsening self-care ability with progressing mental illness. This disease may potentially deteriorate oral health by affecting the subject's ability to perform oral hygiene measures. Literature on oral disease manifestations in schizophrenia is limited. Lack of desire for oral health care as well as generally poor awareness of oral health issues in these patients, compounded further by side effects of medications, may complicate dental management in schizophrenic patients. The present review explores clinical features and possible factors associated with oral health status among those with Schizophrenia.

The Swiss forest and its biodiversity: LiDAR allows for novel forest structure assessments

Availability of comprehensive biodiversity maps and standlevel habitat management recommendations to forest services is often limited, despite the need for such information for multifunctional forestry. Here, we combined forest structural parameters derived from nation-wide available Light Detection and Ranging (LiDAR) data with parameters describing climate, topography and soil pH, to analyse and spatially predict the species richness of different taxa on two different scales. Vascular plants, bryophytes and land snails were analysed on the stand scale (900 m2), where we also identified target variables for habitat management by using data from the National Forest Inventory. On the landscape scale (1 km2), we analysed vascular plants, butterflies and breeding birds with a tight association to forests. LiDAR-derived forest structure parameters were consistently important predictors of species richness across taxa. Species richness patterns tended to be taxon-specific with low spatial congruence across taxa. The habitat quality for many forest land snail species, for example, increased with increasing proportions of trees from the genera Fraxinus, Tilia, Ulmus and Acer, or with increasing overstory cover and deadwood volume. Many butterfly species, on the other hand, responded positively to a heterogeneous understory. This study shows that important structural parameters for forest biodiversity can be derived area-wide and across large regions by using LiDAR. The growing availability of LiDAR data thus provides very useful information for conserving and promoting biodiversity in multifunctional forestry.
Adomnán, two saints, and the paschal controversy
Authors: Márkus Gilbert
Published: May 2017

We have long understood from Bede's testimony that Adomnán, the ninth abbot of Iona, urged his monks to adopt the relatively new 19-year paschal cycle, but they – or many of them – remained faithful to the 84-year cycle which they had inherited. There are passages in Vita sancti Columbae which show Adomnán using stories about St Columba in an attempt to deal with this situation, first of all to reduce the harm done to the community by the disagreement, urging fraternal charity; and secondly, as argued here for the first time, by using contrasting stories about two other saints, Ernéne and Fintan, to persuade his monks that Columba had prophetically foreseen the dispute over the Easter date, and that he had ‘cast his vote’, so to speak, with the saint associated with the 19-year cycle.
Pittenweem Priory and the conventuality question
Authors: Lodge Anthony
Published: May 2017

Pittenweem Priory began life as the caput manor of a daughter-house established on May Island by Cluniac monks from Reading (c. 1140). After its sale to St Andrews (c. 1280), the priory transferred ashore. While retaining its traditional name, the ‘Priory of May (alias Pittenweem)’ was subsumed within the Augustinian priory of St Andrews. Its prior was elected from among the canons of the new mother house, but it was many decades before a resident community of canons was set up in Pittenweem. The traditional view, based principally on the ‘non-conventual’ status of the priory reiterated in fifteenth-century documents, is that there was ‘no resident community’ before the priorship of Andrew Forman (1495–1515). Archaeological evidence in Pittenweem, however, indicates that James Kennedy had embarked on significant development of the priory fifty years earlier. This suggests that, when the term ‘non-conventual’ is used in documents emanating from Kennedy's successors (Graham and Scheves), we should interpret it more as an assertion of superiority and control than as a description of realities in the priory.
