A lattice-based representation of power systems dedicated to synchronism analysis
Authors: Li Xiang , Maïzi Nadia , Mazauric Vincent
Published: January 2019

An energy-efficient description of electromagnetism based on a reversible interpretation of Faraday’s Law is described. Space aggregation and time reconciliation of all scales involved in power system management are derived from two constants of motion, respectively Gibbs free energy and kinetic energy embedded in the whole system. At the upper space scale, a simplified description of the grid based on the Kuramoto model is proved to be suitable for assessing the stability of the synchronous state of a power system. In addition, the Gibbs free energy embedded in the power grid takes the form of a X − Y lattice-gas Hamiltonian, showing the critical role of reactive power in maintaining synchronism. Finally, the transient stability of the power system is considered from these two constants of motion, before any operation from the dispatch.

Policy and Security Configuration Management Systems in Cross-Organisational Settings
Authors: Pudenz Sascha , Manhart Markus , Bachlechner Daniel , Thalmann Stefan
Published: January 2019

A context of use analysis is an important step in every software engineering project. Comprising the identification of the key system users as well as an analysis of the system environment and the activities supported, this engineering step is crucial for the successful development of information systems. Clarity with respect to the users’ demand for system support and their participation in the activities supported by the system is considered particularly important for systems which are critical for organizational continuity and which are used across organizational boundaries. Systems supporting policy and security configuration management in networks of IT service providers, their customers and auditors meet both of these criteria. Within the scope of this article, the context of use of such a system supporting policy and security configuration management is investigated by means of a user-oriented approach. The focus lies on a specific setting being investigated within the scope of an on-going research project. The investigation which was based on a series of qualitative interviews as well as desk research resulted in a comprehensive description of the participation of a set of key system users in activities related to policy and security configuration management as well as their demand for system support. Also the key users and the activities to be supported are discussed within the scope of this article.
The New Public Management In Transition Countries- Public Sector Decentralization And Local Governance Reform In Kosovo
Authors: Krasniqi Ibrahim
Published: January 2019

Public administration management in most developing countries is changing rapidly through reform processes with respect to public service delivery and the stimulation of economic growth. That change, in general is affected by the need for policy reform, has resulted in different structural public management reforms known as decentralization and ‘the new public management’, reflecting a movement away from the old values and norms of public administration management. This paper discusses the issue of local government reform processes in Kosovo in parallel with the new public management processes in the country. Local government reform has been and is a priority of the institutions of the Republic of Kosovo, and as such, it has gone through various stages of its evolution. In other words, special emphasis should be put also on the achievements, progress, challenges and difficulties of local government reform processes. As such, this paper reflects the ontological aspect of the new public management approach in local government reform in the Republic of Kosovo, starting from the development stages of this extensive process up to the current situation, including falls and downs of this process. Therefore, this paper reflects empirically (through research) the current status of local government in Kosovo, as well as the difficulties faced by the local government. As a result of the elaboration of this paper, we have come to the conclusion that local government has made a significant progress since the end of the war. However, much remains to be done in this regard, especially in terms of: transparency, accountability, citizen participation in decision-making, and many other processes, which further strengthen local democracy in the country.

After identifying them, the same elements (now national) will be used to declare the national heritage in Macedonian houses. Secondly, we would like to compare the same elements found as Macedonian with other places, like Turkey (involving Bursa, Istanbul and other cities), to see if they really are different as those from houses in Turkey, or there is a similarity between them.
ITU-PRP: Parallel and Distributed Computing Middleware for Java Developers
Authors: Spahi Enis , Altilar D.
Published: January 2019

ITU-PRP provides a Parallel Programming Framework for Java Developers on which they can adapt their sequential application code to operate on a distributed multi-host parallel environment. Developers would implement parallel models, such as Loop Parallelism, Divide and Conquer, Master-Slave and Fork-Join by the help of an API Library provided under framework. Produced parallel applications would be submitted to a middleware called Parallel Running Platform (PRP), on which parallel resources for parallel processing are being organized and performed. The middleware creates Task Plans (TP) according to application’s parallel model, assigns best available resource Hosts, in order to perform fast parallel processing. Task Plans will be created dynamically in real time according to resources actual utilization status or availability, instead of predefined/preconfigured task plans. ITU-PRP achieves better efficiency on parallel processing over big data sets and distributes divided base data to multiple hosts to be operated by Coarse-Grained parallelism. According to this model distributed parallel tasks would operate independently with minimal interaction until processing ends.
The socio-cultural and political significance of coffeehouses and coffee culture during the independence processes of Kosovo
Authors: Bajmaku Ajhan , Nartar Cinar
Published: January 2019

The coffee culture in the Balkans spread and developed as the Ottoman Empire began using the region as a base that opened into Europe. This region with great strategic significance draws attention not only because it functioned as a bridge between the East and the West but also because of cultural and political values in perspective of the process of changes and developments that have taken place throughout time. As an establishment the coffeehouse is a vital concept for society. Beside their fundamental functions, coffeehouses have gained additional functions over the course of history. These additional functions are directed by socio-cultural and political behaviours. This research paper aims to focus on the socio-cultural and political roles of the coffee culture and coffeehouses with regard to the independence and liberation movements that took place with beginning with the disintegration of Yugoslavia, particularly in Kosovo. Within this context, the crucial role of coffeehouses is explained through the struggle every fraction of society went through to keep their own cultural and political identities alive in order to pull through the negative circumstances created in Kosovo by the wars experienced in the region in the 1990s. Furthermore, this paper also aims to reveal the significant role coffeehouses and their spatial functions play when a nation undertakes the immense challenge of emancipation.
Corruption and Tax Evasion: Evidence from Albanian Enterprises
Authors: Kalaj Ermira
Published: January 2019

This article focuses on survey data and qualitative evidence from Albanian manufacturing firms to examine the scale and consequences of corruption and tax evasion at the enterprise level. It discusses the costs and benefits from the entrepreneur’s perspective. The vector of covariates includes information about; use of external finance, policy influence, experience of corruption, firms size and ownership structure. To control for differences in the availability of collateral, the proportion of the fixed assets is included. The models used in the paper are probit where the dependent variable is binary and ordered probit where the dependent variable is categorical and orderable. Empirical results show that manufacturing firms operating in an environment in which tax evasion is more prevalent are more likely to suffer demands for bribes from corrupt officials. The regression analysis shows that tax evasion is a matter of degree and that is not limited to small and medium-sized enterprises. Even quite large firms acknowledge concealing part of their sales from tax authorities. Enterprises that are evading taxes are less likely to obtain an external audit. In addition, the data predict that corruption and tax evasion is more likely to occur when the principal owner is male rather than female. Moreover, findings show that the main effect of the separation of ownership on the likelihood of bribery is insignificant.
The impact of product and labour market deregulation
Authors: Muja Armend
Published: January 2019

Economists have often talked about the European Paradox:” - Europe having the necessary knowledge and research but failing to utilize these advantages and bring them to the markets. The perception, largely attributable to the media reporting, is that Europe lags behind the United States in innovation. While it is true that most of the e-commerce innovations were developed in the United States, Europe’s economies did well over the 1990s despite the lack of major breakthroughs in high-tech sphere. Thus, it is hard to say that Europe is facing an innovation crisis, and I will argue that Europe has other advantages that make it competitive globally. While Europe might not have as much success in innovation as the United States, it nevertheless, has been successful in more developed and mature segments of the markets. Moreover, I will argue that country’s specialization depends on the setup of the institutions in the political economy. The countries utilize their comparative institutional advantage (CIA) to maintain competitive globally. Finally, I will argue against the idea of drastic deregulation of the product and labor markets in Europe. Doing so would be like shooting yourself in the foot since individual European countries would lose their comparative institutional advantage that allows them to stay competitive globally in the market for incremental innovation products.
Security Concerns of new alternative telecommunication services
Authors: Hyseni Arbnora , Pireva Krenare , Kajtazi Miranda
Published: January 2019

With the advancing new era of communication, the so-called era of ‘being always online’ many providers offer their services for free. In that sense a small company or a virtual company becomes a huge competitor for different traditional telecommunication providers. Using the same services such as: voice calls, video calls, chat and similar services, the internet technology has made huge changes how users make use of such services . Instead of using these services, users shall install applications that are specialized for offering these services via applications, such as: Viber, WhatsApp, Facebook, Google Talk etc.. During the installation and update of these applications people do not recognize the risks of security and privacy of the information that makes their business vital, and how such information are abused on the fly and reused for unauthorized purposes. Using qualitative and quantitative methods we have conducted an empirical study focused on the usage of “these” services and we have elaborated further the need for increasing the knowledge of people in the area of security and privacy while using “free” services. This paper will highlight the challenges by setting a number of privacy and security concerns that are violated while using “free” online services, also offering a bird’s eye view of numerous recommendations developed by various standard organizations.
Microsimulation Models for Simulating Pathways of Patients with Mental Diseases
Authors: Bauer Andreas , Breitenecker Felix , Urach Christopher
Published: January 2019

Predicting demand for care is necessary to provide sufficient capacities in hospitals and enable better planning to cope with challenges like changes in the structure of the population. Emphasis in this work is put on the analysis of the data and on the parametrization of a simulation model for the paths of patients with mental diseases through the health care system. Survival analysis and model selection methods are used for this purpose. Data on patients and their treatments is analyzed with methods of survival analysis. Different methods for modelling the survival and hazard function are presented and compared. Hereby, the focus is on the cox model. It is used to model the hazard function and can be extended to analyze multiple events. With the use of model selection methods the significant parameters are determined. Only these are included in the simulation model. These methods shall help to raise the quality of the parametrization and therefore the whole simulation model. In the microsimulation model, every patient has a particular set of parameters and can be in one of several predefined, exclusive states. The events are implemented as state changes. The probabilities for the events are calculated using the hazard functions. These are estimated with several extensions of the cox model. The considered events in the simulation are readmissions to hospital and contacts to ambulant psychiatrists. The simulation runs for a predefined time span and the sequence of events of each patient is tracked. After the simulation, the individual paths of the patients as well as aggregated quantities such as the overall numbers of certain events are analyzed. Simulations for different populations are performed. The results for various scenarios are presented. Scenarios with and without contacts to a psychiatrist are considered as well as different maximum numbers of admissions. Also, the subpopulations are compared. For example, differences in the results for diagnosis groups are encountered. These simulations shall lead to an improvement of the prediction of the pathways of the patients and therefore help to evaluate interventions like treatment changes the health care system or the utilization of the capacities in hospitals.
E-learning systems in higher education institutions: An outlook of their use in the Western Balkan Region
Authors: Chaushi Blerta , Chaushi Agron , Ismaili Florije
Published: January 2019

This study provides a review of the literature on e-learning systems evolution and environments. The argument is that e-learning systems should be embedded in the core strategy of the institution. To support this premise, studies for e-learning are analyzed and six recommendations are drawn for universities to follow in order to have successful e-learning environments. The main contribution of this study, however, is the identification of the trends and statistics regarding the e-learning usage in the Balkan region. These stats are identified through a survey conducted in 40 universities in 10 countries from this region. The results show that more than 70% of the universities have adopted LMS, which does not fall short behind when compared with universities in the world. Also, the results show that around 64% of the private universities develop LMS in-house, compared with around 38% of the public universities, which have funding from the governments and can purchase vendor based solutions. However, the results from the survey suggest that public universities in these countries are more prone to open-source rather than vendor based.
Hybrid Modelling in System Simulation
Authors: Körner Andreas
Published: January 2019

In times of increasing power and capacity in computer, simulation mathematical models are getting more and more important. For different technical applications and in natural science but also in economic systems and management processes appropriate mathematical model descriptions are necessary. Hybrid modelling is a special technique for more complex model descriptions in order to reduce the degree of complexity. In different fields of interest, the behavior of a model is dependent on the active state. When the model description is changing from one state to another, a so-called state event takes place. State event modelling is the overall term to describe this modelling approach. One state is defined by one dynamic system description and another state is described by the next description. The mathematical environment of the model allows finding the description which is the best matching one in each state. In this sense it is possible to find the most efficient model description for each state and it is not necessary to build up a complicated model structure to cover all cases in one model. Beside the principle effect of the basic structure it is also possible to combine different mathematical modelling techniques for realizing a hybrid model for a certain complex system. In each case a certain mathematical model of the mathematical method can be provided. This is the formal mathematical definition of a multi method approach. In different states different models are simulated and a certain master algorithm is managing the overall administration of the discrimination. The mentioned issues are covered under the overall term hybrid modelling and will be introduced in the corresponding paper.

Authors: Alghobiri Mohammad , Ishfaq Umer , Khan Hikmat , Malik Tahir
Published: January 2019

The social Web provides opportunities for the public to have social interactions and online discussions. A large number of online users using the social web sites create a high volume of data. This leads to the emergence of Big Data, which focuses on computational analysis of data to reveal patterns, and associations relating to human interactions. Such analyses have vast applications in various fields such as understanding human behaviors, studying culture influence, and promoting online marketing. The blogs are one of the social web channels that offer a way to discuss various topics. Finding the top bloggers has been a major research problem in the research domain of the social web and big data. Various models and metrics have been proposed to find important blog users in the blogosphere community. In this work, first find the sentiment of blog posts, then we find the active and influential bloggers. Then, we compute various measures to explore the correlation between the sentiment and active as well as bloggers who have impact on other bloggers in online communities. Data computed using the real world blog data reveal that the sentiment is an important factor and should be considered as a feature for finding top bloggers. Sentiment analysis helps to understand how it affects human behaviors.
Optimal Control of DC Motors Using PSO Algorithm for Tuning PID Controller
Authors: Myrtellari Arnisa , Marango Petrika , Gjonaj Margarita
Published: January 2019

The DC motors are widely used in the mechanisms that require control of speed. Different speed can be obtained by changing the field voltage and the armature voltage. The classic PID controllers are widely used in industrial process for speed control. But they aren’t suitable for high performance cases, because of the low robustness of PID controller. So many researchers have been studying various new control techniques in order to improve the system performance and tuning PID controllers. This paper presents particle swarm optimization (PSO) method for determining the optimal PID controller parameters to find the optimal parameters of DC Motor speed control system. The DC Motor system drive is modeled in MATLAB/SIMULINK and PSO algorithm is implemented using MATLAB toolbox. The results obtained through simulation show that the proposed controller can perform an efficient search for the optimal PID controller. Simulation results show performance improvement in time domain specifications for a step response (no overshoot, minimal rise time, steady state error = 0).

Published: January 2019

The aim of this study is to determine the anthropometric measurements of the users of outdoor fitness equipment and to re-design of an in-use outdoor fitness equipment according to these measurements.

A total of 100 (50 male and 50 female) outdoor fitness equipment users, living in Eskisehir, Turkey, voluntarily participated in the study. Their ages ranged from 18 to 79 years and the mean of their ages were 31,2 (SD: 1,15277). The following human body dimensions were measured: stature, shoulder height, side-arm reach, fist (knuckle) height, forearm length, upper arm length, shoulder-fingertip length, knee height, malleolus height and hand length. The anthropometric measures of the adults and the outdoor fitness equipment’ dimensions were compared in order to identify any incompatibility between them. The data indicated a mismatch between the adults’ bodily dimensions and the outdoor fitness equipment available to them. Later on, in use fitness equipment’s motion output compared with biomechanical limits. Also, a mismatch was found between the motion output and biomechanical limits which might cause injuries. As these mismatches endanger public health, an outdoor fitness equipment, FE02 Stepper was re-designed according to its users’ anthropometric data and biomechanical limits as an example.

Bu çalışmada amaç; banka çalışanlarının hata yapmasında etkili olan
faktörleri ve insan hatalarını önleyecek önlemleri belirlemektir. Çalışmada 2
yöntem kullanılmıştır. Biri, Reason’ın gizli ve faal hatalarını ana hatları ile
belirlemek için dört hata seviyesinden oluşan, İnsan Faktör Analizi ve
Sınıflandırma Sistemi (İFASS)’dir. Diğer yöntem, karar vericinin
serbest-içerikli dilsel terim setleri kullanılarak görüşlerini ifade etmesinde
zenginlik ve farklı ifadeler kullanma esnekliği sağlayan ve temeli bulanık
dilbilgisine dayanan Çok-Kriterli Kararsız Bulanık Dilsel Terim Seti (ÇK-KBDTS)
yöntemidir. Elde edilen sonuçlara göre, ana faktörlerden Personel faktörü en
çok ağırlığa sahipken, alt kriterlerin global ağırlıklarına göre Fiziksel
Çevre, Teknolojik Çevre sonrasında Zihinsel Sınırlamalar en önemli kriterler
olarak belirlenmiştir. Bankacılık hizmet sektöründe çalışanlarda parasal
mevzularda hata yapma ve bunun sonucunun nelere sebep açacağı korkusu ve
baskısı nedeniyle zihinsel sınırlamaların payı yüksektir. Literatüre
bakıldığında İFASS yönteminin hizmet sektöründe sadece hastanelerde uygulandığı
görülmüştür. Bu çalışmada ilk defa, bankacılık sektöründe hata faktörleri ele
alınmış ve İFASS&ÇK-KBDTS yöntemleri entegre edilmiştir. Bu nedenle çalışmanın
literatüre katkısı olacağı düşünülmektedir.
Degradation Kinetics of Clavulanic Acid in Fermentation Broths at Low Temperatures

Published: January 2019

Clavulanic acid (CA) is a β-lactam antibiotic inhibitor of β-lactamase enzymes, which confers resistance to bacteria against several antibiotics. CA is produced in submerged cultures by the filamentous Gram-positive bacterium Streptomyces clavuligerus; yield and downstream process are compromised by a degradation phenomenon, which is not yet completely elucidated. In this contribution, a study of degradation kinetics of CA at low temperatures (−80, −20, 4, and 25 °C) and pH 6.8 in chemically-defined fermentation broths is presented. Samples of CA in the fermentation broths showed a fast decline of concentration during the first 5 h followed by a slower, but stable, reaction rate in the subsequent hours. A reversible-irreversible kinetic model was applied to explain the degradation rate of CA, its dependence on temperature and concentration. Kinetic parameters for the equilibrium and irreversible reactions were calculated and the proposed kinetic model was validated with experimental data of CA degradation ranging 16.3 mg/L to 127.0 mg/L. Degradation of the chromophore CA-imidazole, which is commonly used for quantifications by High Performance Liquid Chromatography, was also studied at 4 °C and 25 °C, showing a rapid rate of degradation according to irreversible first-order kinetics. A hydrolysis reaction mechanism is proposed as the cause of CA-imidazole loss in aqueous solutions.
Damage Analyses of Replaceable Links in Eccentrically Braced Frame (EBF) Subject to Cyclic Loading
Authors: Yin Zhanzhong , Feng Dazhe , Yang Wenwei
Published: January 2019

In the current design of steel eccentrically braced frames (EBFs), the yielding link is coupled with the floor beam. This causes the design of cross-sectional dimensions of links to be enlarged, resulting in over-designed structures and foundations, and increasing the cost of the overall structure. In addition, the beams are forecast to sustain severe damage through repeated inelastic deformations under design-level earthquakes, and thus the structure may require extensive repair or need to be replaced. To improve upon these drawbacks, a shear device with replaceable links based on EBFs was designed. The hysteresis curve, the stress distribution, and the deformation of the specimen were obtained by cyclic loading tests of the eight replaceable links. The energy dissipation behavior, the bearing capacity, the failure modes, and the plastic rotation angle of those specimens were analyzed. The results indicated clearly that the links in this shear device had inelastic deformation concentrated in the link showing very stable hysteresis behavior, and damaged links were replaced easily as end-plate connections were adopted. The energy dissipation capacity and the plastic rotation angle of the specimens were mainly dependent on the arrangement of stiffener, length ratio, and welding access holes. Experimental studies performed in this research and the related damage analyses reveal that cracks are the major causes of damage to the EBF and there is a lack of research on real-time monitoring of the onset and development of these cracks in EBF structures. As a future work, this paper proposes a piezoceramic patch transducer-based active sensing approach to monitor the crack onset and development of the EBF when subjected to dynamic loadings.

Published: January 2019

The straight-through magneto-optical glass current sensor has desirable temperature properties, but it is vulnerable to magnetic interference. In contrast, a polarization-type fiber optic current sensor has poor temperature performance, but the magnetic anti-interference characteristic is very good. Aiming at the problem that the accuracy of a fiber optic current sensor is susceptible to external disturbances and temperature fluctuations, we present an adaptive technology of a fiber optic current sensor that uses the magneto-optical output signal to correct the fiber output signal. The working principle of the improved method is introduced in this paper. The structure of the specific optical system and the signal processing system are presented. Temperature fluctuation and magnetic change detection units are included in the design in order to provide signal selection under different environmental fluctuations, thus stabilizing the output current data. The signal processing system was proved to be effective by building an experimental platform.

Microorganisms producing laccases may be used for the pretreatment of lignocellulosic biomass to recover fermentable sugar. Very few fungi and other microbes growing in high altitudes have been tested for this purpose. As part of this study, we have collected soil samples from different parts of the Kathmandu Valley and the Rautah at district of Nepal (1600 to 2303 m above sea level) and successfully cultured 53 different isolates of microorganisms. Among the 53 isolates obtained 30 were Actinomycetes, 20 were Streptomycetes, and three were fungi). These isolates were tested for laccase expression using guaiacol, tannic acid, and 1-naphthol as substrates. Twelve of the 53 isolates tested positive for the expression of laccase. Among the laccase- positive isolates, a fungal species designated as CDBT-F-G1was found to produce high levels of laccase. This isolate was identified as Pestalotiopsis species based on 18S rRNA sequencing. Pestalotiopsis spp. CDBT-F-G1 isolate grows efficiently in PDB media containing 1% Kraft lignin at pH 5 and 30 °C and secretes 20 ± 2 U/mL laccase in culture medium. Further optimization of growth conditions reveled that addition of (i) metal salts, e.g., 1 mM magnesium sulfate (51 ± 25 U/mL); (ii) agitation of cultures at 200 rpm (51 ± 9U/mL); (iii) surfactants, e.g., 0.75 mM Tween 80 (54 ± 14 U/mL); (iv) 40% dissolved O2 (57 ± 2 U/mL) and inducers, e.g., 1 mM gallic acid (69 ± 11 U/mL), further promote laccase production by Pestalotiopsis spp. CDBT-F-G1 isolate. On the other hand, 0.1 mM cysteine inhibited laccase production. The secretory laccase obtained from fermentation broth of CDBT-F-G1 was partially purified by ammonium sulfate (13-fold purification with specific activity 26,200 U/mg) and acetone (14-fold purification with specific activity 31,700 U/mg) precipitation methods. The enzyme has an approximate molecular mass of 43 kDa, pH and temperature optima werepH6 and 60 °C, respectively. Vmax and Km were 100 μmol/min and 0.10 mM, respectively, with ABTS as the substrate. Given the above characteristics, we believe Pestalotiopsis spp. CDBT-F-G1 strain native to high altitudes of Nepal could be used to pretreat lignocellulosic biomass to efficiently recover fermentable sugars.
