Gradient characteristics of a detection field for image data
Authors: Czapla Zbigniew
Published: March 2019

The paper presents a method of determination of gradient characteristics describing a detection field. The presented method is destined for image data. Image data are in the form of a source image sequence. Frames taken from a video stream, obtained at a measurement station, create a source image sequence. The same detection field is defined for all images of the source image sequence. The source image sequence is converted into binary form. Conversion is carried out on the basis of analysis of source images gradients. Layout of obtained binary vales of target images is in accordance with a content of source images. In the area of detection field, arithmetic and averaging sums of binary values are appropriately calculated. On the bases of averaging sums of binary values, gradient characteristics of the detection field are determined. Gradient characteristics of detection field are intended for vehicle detection and also can be utilized for vehicle speed determination or vehicle classification..

Models for estimating the time of program loop execution in parallel on a CPU and with the use of OpenCL computation on a GPU
Authors: Nozdrzykowski Łukasz , Nozdrzykowska Magdalena
Published: March 2019

The authors present models for estimating the time of execution of program loops compliant with the FAN model with no data dependencies or with data dependencies only within the body programming loop, which can be executed either by CPUs or by stream multiprocessors referred to as GPU cores. The models presented will make it possible to determine whether it would be more efficient to execute computation in the existing environment using the CPU (Central Pro-cessing Unit) or a state-of-the-art graphics card with a high-performance GPU (Graphics Processing Unit) and super-fast memory, of-ten implemented in modern graphics cards. Validity checks confirming the developed time estimation model for GPU are presented. The purpose of these models is to provide methods for accelerating the performance of applications performing various tasks, including transport tasks, such as accelerated solution searching, searching paths in graphs, or accelerating image processing algorithms in vision systems of autonomous and semiautonomous vehicles, where these models allow to build an automatic task distribution system between the CPU and the GPU with the variability of computing resources.

Computing metric dimension of compressed zero divisor graphs associated to rings
Authors: Pirzada S. , Bhat M. Imran
Published: March 2019

For a commutative ring R with 1 ≠ 0, a compressed zero-divisor graph of a ring R is the undirected graph ΓE(R) with vertex set Z(RE) \ {[0]} = RE \ {[0], [1]} defined by RE = {[x] : x ∈ R}, where [x] = {y ∈ R : ann(x) = ann(y)} and the two distinct vertices [x] and [y] of Z(RE) are adjacent if and only if [x][y] = [xy] = [0], that is, if and only if xy = 0. In this paper, we study the metric dimension of the compressed zero divisor graph ΓE(R), the relationship of metric dimension between ΓE(R) and Γ(R), classify the rings with same or different metric dimension and obtain the bounds for the metric dimension of ΓE(R). We provide a formula for the number of vertices of the family of graphs given by ΓE(R×𝔽). Further, we discuss the relationship between metric dimension, girth and diameter of ΓE(R).
Linkage of the Manín and Klape units with the Pieniny Klippen Belt and Central Western Carpathians: balancing the ambiguity
Authors: Plašienka Dušan
Published: March 2019

The paper deals with the structure and evolution of the Pieniny Klippen Belt in its classic area in western Slovakia. The so-called Peri-Klippen Zone provides a transition from the Pieniny Klippen Belt s.s. built up by Jurassic to Eocene Oravic units (Šariš, Subpieniny and Pieniny from bottom to top) to the outer margin of the Central Western Carpathians composed of Triassic to mid-Cretaceous successions of the Fatric and Hronic cover nappe systems. The Peri-Klippen Zone attains a considerable width of 15 km in the Middle Váh River Valley, where it is composed of the supposedly Fatric Manín, Klape and Drietoma units, as well as their post-emplacement, Gosau-type sedimentary cover. All these units are tightly folded and imbricated. The complex sedimentary and structural rock records indicate the late Turonian emplacement of the frontal Fatric nappes in a position adjacent to or above the inner Oravic elements, whereby they became constituents of an accretionary wedge developing in response of subduction of the South Penninic– Vahic oceanic realm separating the Central Western Carpathians and the Oravic domain. Evolution of the wedge-top Gosau depressions and the trench-foredeep basins of the foreland Oravic area exhibit close mutual relationships controlled by the wedge dynamics. The kinematic and palaeostress analyses of fold and fault structures revealed only one dominating stress system coeval with development of the accretionary wedge, which is characterized by the generally NW–SE oriented main compression axis operating in a pure compressional to dextral transpressional regime, interrupted by short-term extensional events related to the wedge collapse stages. Younger, Miocene to Quaternary palaeostress fields correspond to those widely recorded in the entire Western Carpathians. Relying on the regional tectonostratigraphic and structural data, the problematic issues of the palaeogeographic settings of the Manín and Klape units, presumably affiliated with the Fatric cover nappe system, and of the provenance of numerous olistoliths occurring at different stratigraphic levels are then discussed in a broader context.
Toxicity assessment of agrochemical Almix in Heteropneustes fossilis through histopathological alterations
Authors: Samanta Palas , Das Rituparna , Pal Sandipan , Mukherjee Aloke Kumar , Senapati Tarakeshwar , Kole Debraj , Ghosh Apurba Ratan
Published: March 2019

The present study was designed to assess the adverse effects of the agrochemical Almix on comparative basis in gill, liver and kidney of Heteropneustes fossilis through histological and ultrastructural observations under field (8 g/acre) and laboratory (66.67 mg/L) conditions. Exposure duration of both experiments was 30 days. Gill showed atrophy in secondary lamellae, hypertrophied gill epithelium, damage in chloride and pillar cells, and detachment of chloride cells from gill epithelium under laboratory condition, but hypertrophy in gill epithelium and fusion in secondary lamellae were seen under field condition. In gill, scanning electron microscopy (SEM) showed fragmentation in microridges, hyper-secretion of mucus and loss of normal array in microridges, while transmission electron microscopy (TEM) displayed dilated mitochondria and rough endoplasmic reticulum (RER), abnormal sized vacuolation in chloride cells under laboratory condition. In liver, hypertrophied and pyknotic nuclei, disarrangement of hepatic cords, and cytoplasmic vacuolation were prominent under laboratory study but in field condition the liver showed little alterations. TEM study showed severe degeneration in RER and mitochondria and cytoplasmic vacuolation under laboratory condition but dilated mitochondria were prominent in field observation. Kidney showed severe nephropathic effects including degenerative changes in proximal and distal convolute tubule, damage in glomerulus under light microscopy, while deformity in nucleus, fragmentation in RER, severe vacuolation and necrosis in kidney were prominent under TEM study. The results clearly demonstrated that responses were more prominent in laboratory than field study. Thus the responses displayed by different tissues of concerned fish species exposed to Almix could be considered as indications of herbicide toxicity in aquatic ecosystem.
Radicals initiated by gamma rays in selected amino acids and collagen
Authors: Przybytniak Grażyna , Sadło Jarosław , Dąbrowska Małgorzata , Zimek Zbigniew
Published: March 2019

Calf skin collagen and three amino acids essential for its structure, namely glycine, L-proline and 4-hydroxyl-L-proline, were irradiated with gamma rays up to a dose of 10 kGy. Conversion of radicals over time or after thermal annealing to selected temperatures was monitored by X-band electron paramagnetic resonance (EPR) spectroscopy. Some experimental spectra were compared with signals simulated based on literature data from the electron nuclear double resonance (ENDOR) studies. The following phenomena were confirmed in the tested amino acids: abstraction of hydrogen atom (glycine, proline, hydroxyproline, collagen), deamination (glycine, hydroxyproline), decarboxylation (hydroxyproline). Chain scission at glycine residues, radiation-induced decomposition of side groups and oxidative degradation were observed in irradiated collagen. The decay of radicals in collagen saturated with water occurred at lower temperatures than in macromolecules having only structural water. The paramagnetic centres were the most stable in an oxygen-free atmosphere (vacuum). Radical processes deteriorated the structure of collagen; hence, radiation sterilization of skin grafts requires careful pros and cons analysis.
Effect of electronic cigarette (EC) aerosols on particle size distribution in indoor air and in a radon chamber
Authors: Khalaf Hyam Nazmy , Mostafa Mostafa Y. A. , Zhukovsky Michael
Published: March 2019

Particle size distribution is an important factor governing whether aerosols can be deposited in various respiratory tract regions in humans. Recently, electronic cigarette (EC), as the alternative of tobacco cigarette, has become increasingly popular all over the world. However, emissions from ECs may contribute to both indoor and outdoor air pollution; moreover, comments about their safety remain controversial, and the number of users is increasing rapidly. In this investigation, aerosols were generated from ECs and studied in the indoor air and in a chamber under controlled conditions of radon concentration. The generated aerosols were characterized in terms of particle number concentrations, size, and activity distributions by using aerosol diffusion spectrometer (ADS), diffusion battery, and cascade impactor. The range of ADS assessment was from 10−3 μm to 10 μm. The number concentration of the injected aerosol particles was between 40 000 and 100 000 particles/cm3. The distribution of these particles was the most within the ultrafine particle size range (0–0.2 μm), and the other particle were in the size range from 0.3 μm to 1 μm. The surface area distribution and the mass size distribution are presented and compared with bimodal distribution. In the radon chamber, all distributions were clearly bimodal, as the free radon decay product was approximately 1 nm in diameter, with a fraction of ~0.7 for a clean chamber (without any additional source of aerosols). The attached fraction with the aerosol particles from the ECs had a size not exceeding 1.0 μm.
First record of Hyposoter placidus (Desvignes, 1856) (Hymenoptera: Ichneumonidae) in Poland: the specialized parasitoid of Lycaena Fabricius, 1807 butterflies (Lepidoptera: Lycaenidae)
Authors: Sielezniew Marcin , Kostro-Ambroziak Agata
Published: March 2019

Adult ichneumonids of Hyposoter placidus were reared from caterpillars of the large copper butterfly Lycaena dispar collected in NE Poland, feeding on Rumex confertus, R. hydrolapathum and R. obtusifolius. This is the first record of this parasitoid in the country. We hypothesize that H. placidus may be a factor limiting the abundance of populations of L. dispar, a widespread species but usually occurring in low numbers.

Published: March 2019

Entrepreneurial spirit plays an increasingly important role in the economic sphere, and universities are meant to play a central role in this process, where the main objective is the continuous development and mediation of the knowledge increasingly geared to the applications through innovation and patenting a secure platform for employment and well-being growth. The Universities have to take a position in if/and how they want to grow into a so-called “University of Entrepreneurship” which is characterized by a high degree of openness to the surrounding society and here we are talking, especially, about, the business sector in Romania. This evolution of expectations for the social role of universities has resulted from increased and recent interest in entrepreneurship and innovation of areas as research and theory of the business environment. The experience gained as teachers indicates that education and entrepreneurship education should include different theories and methodology than those applied in the usual way. The theory of traditional management and microeconomic models could even be a barrier to new thinking and change and, therefore, to the implementation of modern entrepreneurial actions. We want this article to be a source of inspiration for educational institutions and to have a positive contribution to research in business education and to be applicable in business decision-making.
Innovative Model of Management and University Quality through Results Indicators; the KPI’s Cross Impact Matrix of the Universidad Bernardo O’Higgins
Authors: Escobar Claudio Ruff , Toledo Marcelo Ruiz
Published: March 2019

Currently, higher education faces the great challenge of promoting the enduring improvement of its actions, and thus achieve not only satisfaction and integral formation of its students, but also a permanent growth and institutional development. At the World Conference of Higher Education, CMES 2009, the subject of quality and university management was emphasized, understanding that both favor the decision-making that directly benefits the continuous progress by incorporating mechanisms and instruments that ensure quality, such as: the hiring of qualified personnel, the optimization of resources and the accomplishment of institutional goals.

The Universidad Bernardo O’Higgins has defined and specified in its 2016-2020 institutional strategic plan, strategic objectives and indicators that show their degree of effectiveness through a Balanced Scorecard System. For this, it was necessary to select and specify indicators of relevant performance (KPIs) which would allow to execute a more specific follow up to overall performance and results. By using a similar methodology to the Dupon analysis a crossed-impact matrix was designed, which classified the 31 identified indicators in 4 KPIs of general matrix performance that allowed to systematically evaluate the institution and assess its integral overall performance by looking at only 4 indicators referring to the degree of advancement and institutional quality.

Thus, achieving the study’s goal by designing and implementing a modern management model sustained in key indicators that might influence the institutional quality, measured through the institutional and careers accreditation and the correlation analysis between years and accreditation areas and the selected indicators.

So why it is accentuated that personal charisma of a social worker is a constellation of complex social and emotional skills that allows charismatic individuals to influence others at deep emotional levels, communicate effectively with them, and build strong interpersonal relationships. Authors of the article discuss the possible answers to the following research question: How to recognize, accept and (self)develop personal charisma in social work? In the article the interdisciplinary pont of view is provided and amotional and social skills are discussed in relation to social worker‘s charisma.

Authors conclude that Some of charisma-related skills are born innate, others are perfected over time, but the most important is proper application of skills. Charisma of a social worker is related to emotional intelligence, which consists of self-awareness, self-regulation, motivation, empathy and social skills. Different social work situations require differently developed skills, which msut be developed through long life education, in which the self-managed learning through interactions and within the professional environment must be the priority.
Union Democracy and the Law in Canada
Authors: Lynk Michael
Published: March 2019

The legal approach in Canada towards the regulation of trade union democracy has sought to balance individual member's rights with respect for the autonomy of unions. While the United States and England have heavily legislated the areas of internal trade union affairs, Canada has enacted relatively few laws in this area. Rather, unions in Canada have enjoyed considerable legal freedom to develop their own democratic practices and culture. The irony of this approach is that it is the Canadian courts, rather than the more experienced and liberal labour relations boards, that are the final legal arbiters over most internal union matters. However, this is slowly changing. Several provinces have recently enacted modest changes that direct their labour boards to hear complaints from union members respecting the fairness of internal hearings. In the absence of extensive statutory regulation, union constitutions and the democratic traditions behind them become significant legal documents. Au Canada, l’approche juridique à l’égard de la réglementation de la démocratie syndicale a consisté à chercher à mettre en équilibre les droits des membres et l’autonomie des syndicats. Les États-Unis et l’Angleterre ont une multitude de lois sur les affaires internes des syndicats, mais le Canada n’a adopté que relativement peu de lois à cet égard. Les syndicats du Canada ont joui d’une liberté juridique considérable dans l’établissement de leurs pratiques et de leur culture démocratiques. L’ironie de cette approche est que ce sont les tribunaux canadiens plutôt que les conseils des relations du travail, plus expérimentés et ayant moins de préjugés, qui sont les arbitres de dernier recours sur la plupart des questions syndicales internes. Toutefois, la situation change peu à peu. Plusieurs provinces ont adopté dernièrement de modestes modifications législatives ordonnant à leurs conseils des relations du travail d’entendre les plaintes de membres de syndicats au sujet de l’équité des audiences internes. En l’absence d’une réglementation étoffée, les statuts des syndicats et les traditions démocratiques qui les sous-tendent deviennent d’importants documents légaux.
The Labour Movement and Civil Society: Reflections on the People’s Summit from Quebec
Authors: Gagnon Mona- Josee
Published: March 2019

This paper reflects on the Québec labour movement and its present role as a political actor, particularly its ability to reestablish itself as a agent of meaningful social change. It is argued that Québec labour’s involvement in the People’s Summit in April, 2001 protesting the Summit of the Americas meetings in Québec City and the movement’s general embrace of many aspects of the anti-globalization agenda mark an historical turning point. The change of direction will not only affect the relationships among different Québec unions, but relations among unions, the state, and community groups, as well as international relations between unions based in the North and South. Cet article propose une réflexion sur le syndicalisme québécois coonsidéré comme acteur politique et, plus particulièrement, sur sa capacité à redevenir un agent de changement social profond. Le contre_sommet d'avril 2001 à Québec et, plus globalement, l'appropriation syndicale du dossier de la mondialisation, apparaît comme un point tournant, si l'on se situe dans une perspective historique. Les axes de changement éventuel concernent le rapport entre syndicalisme, État et mouvement associatif, de même que les syndicats du Nord et du Sud
Engineering Resistance : Energy Professionals and the 2005 Strike in Neoliberal Ontario
Authors: Coulter Kendra
Published: March 2019

In the summer of 2005, the Society of Energy Professionals Hydro One Local engaged in unprecedented strike action that lasted 105 days. This article documents the strike, and explores how and why it occurred, and with such significant support and participation from the 1000 members of a union that had no militant history. I trace the build-up, progression and resolution of the strike, drawing from Society materials, media reports and ethnographic observation, as well as the insights of elected leaders, staff representatives, and rank and file members of the Society collected through interviews and written questionnaires. I conclude that government policy and management behaviour caused worker anger but that union education, organization and democracy were integral to moving these “professional” workers into job action.
Regulation of Child and Adolescent Employment in Alberta
Authors: Barnetson Bob
Published: March 2019

As part of a broader assessment of how well the Government of Alberta’s labour programming contributes to fair and, to a lesser degree, safe workplaces, this study examines how effectively the government enforces the Employment Standards Code provisions regulating child and adolescent employment. Enforcement strategies appear to emphasize softer forms of regulation and thereby create little disincentive for violations. Preliminary research into the employment levels of children (age 9-11) suggests over 11,000 children are employed, some perhaps illegally, and that further inquiry into their employment experiences is warranted.
The Targeted Wage Subsidy: How Program Design Creates Incentives for “Creaming”
Authors: Lahey Pam , Hall Peter V
Published: March 2019

Across most developed nations, including Canada, parallel systems of social welfare and employment insurance have increasingly been replaced by programs that emphasize work as a means to achieve welfare goals within the so-called re-employment framework. Various authors have drawn attention to the tension between the goal of long-term sustainable employment, and re-employment-based strategies that emphasize short-term and stand-alone interventions. In this paper, we focus on the implementation of one such program in Canada, the Targeted Wage Subsidy. This program seeks to place the most marginal qualifying participants in employment by offering employers a financial inducement. By paying close attention to the experiences of those tasked with monitoring and implementing the program in Toronto, we identify various ways in which program design elements may systematically disadvantage the intended recipients. These program delivery mechanisms are shaped both in the practices of implementing agents, as well as by the public accountability framework that enforces rigid timelines and reporting requirements, resulting in a practice commonly referred to by employment service providers as “creaming.” Our observations lead us to question whether the target population is, in fact, the one benefiting from these return-to-work supports.

Authors: SANALAN BİLİCİ Nilgün
Published: March 2019

Bu çalışmada turizm sektörünün yıllar içerisindeki özsermaye karlılıklarının değişimi incelenmiştir. Sektörün özsermaye karlılığının değişiminden yola çıkarak, gelecek yıllara dair tahminler yapılması ve bu doğrultuda yapılacak olan çalışmalara da katkı sağlanması amaçlanmıştır. T.C Merkez Bankası’ndan alınan konaklama ve yiyecek-içecek alt sektöründe bulunan 9.341 firmanın 2010-2016 yılları arası bilançoları ve gelir tablolarındaki verilerin ortalamaları kullanılarak, söz konusu firmaların özsermaye kârlılıklarının yıllar arasındaki değişimi değerlendirilmiştir. Değerlendirme yapılırken net kar marjı (ROS), aktif karlılığı (ROA), özsermaye karlılığı (ROE) yıllar itibariyle belirlenerek irdelenmiştir. Sektör ortalama verileri kullanılarak belirlenen 2010-2014 yıllarına ait ROS, ROA ve ROE’de önemli sapmalar olmadığı belirlenmiştir. 2011 yılında meydana gelen zararın ertesi yıl telafi edilebilir olduğu gözlemlenmiştir. Net kar marjının, özsermaye karlılığını aktif karlılığından daha fazla etkilediği söylenebilir. Değerlendirme sonucunda, 2016 yılında maliyet ve giderlerin satışlara oranla daha düşük olmasının nedeni, net kâr marjının yüksek olması ve bu sayede özsermaye kârlılığı ve aktif kârlılığının pozitif yönde ve maksimum düzeyde gerçekleşmesi olarak değerlendirilmiştir. Sektör özsermaye karlılığı özellikle 2016 da diğer yıllara göre oldukça yüksek çıkmıştır. Bu durum kaynakların kullanımında verimliliğin artmakta olduğu anlamına gelmektedir. Sonuçta 2016 yılında özsermaye karşılığında aktifler üzerinden elde edilen karın yeterli düzeyde olduğu ifade edilebilir. Yine 2016 itibariyle işletmelerin kârı verimli kullanarak, performanslarını artırdıkları söylenebilir.

Sosyal medya, teknolojik gelişmelerle birlikte giderek gelişen dijital dünyaya ayak uydurmaya çalışan ve yenilikleri yakından takip etmek isteyen kurumlar için çok önemlidir. Hızı ve geniş etki alanı sayesinde kurumlara sayısız katma değer sağlayan sosyal medya, kurumların önemli bir parçası konumundadır. Her geçen gün yeni bir işlevi keşfedilen sosyal medyanın kurumlar için önemi giderek artmaktadır. Ancak sosyal medya yapısal özelliklerinden dolayı önemli riskler barındırmaktadır. Sosyal medya riskleri doğru bir şekilde yönetilmediği takdirde kurumlar açısından ciddi bir tehlike arz etmektedir. Kurumlar için önemli bir tehdit unsuru olan sosyal medya risklerinin yönetilmesi hususunda, iç denetimin önemli sorumlulukları bulunmaktadır. Bu çalışmada sosyal medya konusunda iç denetimin üstlendiği sorumluluklar anlatılmaktadır.

Published: March 2019

Borsa İstanbul pay piyasası açısından temel endeks niteliğinde olan Borsa İstanbul 100(BİST 100) Endeksi, piyasa değeri ve işlem hacmi en yüksek olan paylardan oluştuğundan, Borsa İstanbul’un durumunu en iyi yansıtan endeks olma özelliğini taşımaktadır. Bu endeksi etkileyen çeşitli makroekonomik değişkenler söz konusudur. Çalışmada, söz konusu makroekonomik değişkenlerden enflasyon ve dış ticaret açığının 2004:M1 – 2017:M12 dönemlerinde BİST 100 Endeksiyle olan ilişkisi, Johansen ve Gregory&Hansen eşbütünleşme testleri kullanılarak incelenmiştir. Eşbütünleşme testleri yapılmadan önce, birim kök içeren her değişkenin aynı seviyede durağan olmaları gerektiği varsayımı altında, hem geleneksel birim kök testi olan ADF (Augmented Dickey Fuller), hem de yapısal kırılmaları göz önüne alan LS (Lee &Strazicich) birim kök testleri yapılmıştır. Serinin durağan olmayan bazı değişkenleri de durağan hale getirildikten sonra VAR (Vector Autoregressive)modeli uygulanmıştır. Yapılan analizler sonucunda, değişkenler arasında uzun dönemli bir ilişkinin varlığı iki farklı eşbütünleşme testi ile desteklenmiştir. Ayrıca, BİST 100 Endeksinde kısa dönemde meydana gelen oynaklıklar, 14 aylık periyotla uzun dönem dengesine ulaşmaktadır.

Published: March 2019

Due to the drill pipe in the Riserless Mud Recovery (RMR) system is exposed to seawater, so the characteristics of the temperature changing are very different from the conventional offshore drilling. Considering temperature is an important factor affecting the annulus pressure, it is necessary to study the variation law of the temperature field of the RMR. In this paper, according to the physical process of the heat transfer in RMR, the mathematical model of the temperature field is established. The Computational Fluid Dynamics (CFD) software is used to simulate the temperature distribution in the drill pipe and the annulus, so that the law of the temperature changing can be observed more intuitively. In order to be more aware of the influencing factors of the temperature field changing, this paper analyzes the influence mechanism of the different discharge capacity and the different injection temperature on temperature changing. Moreover, this paper also analyzes the influence of the annulus temperature on the annulus pressure, which provides a theoretical basis for the well control of RMR.

The reaction of toluene (T) with OH● produces addition products as well as the benzyl radical (TR). TR can react with OH● or O2 to produce oxygenated species, for many of which there is no experimental information available. We present here theoretically determined heats of formation (HFs) of 17 such species using the non-isodesmic reactions on the potential energy surface (PES) of TR+O2 and T+OH●+O2. For those species the experimental HFs of which are known, we obtained a good correlation between experimental and theoretical values at the G4 (r2=0.999) and M06/cc-pVQZ (r2=0.997) levels, thus showing the goodness of the methods used. Previously unknown HFs of other radicals (benzyloxyl, spiro [1,2-dioxetane benzyl], hydroxyphenyl, and benzylperoxyl) and closed shell species (salicylic alcohol, benzo[b]oxetane and p-hydroxy cyclohexa-2,5-dienone) were later determined using those methods.
