Simulation of Observer Based Tracking Control for the Longitudinal Dynamics Model of a Vertical Takeoff and Landing Aircraft
Authors: Makarov D. A.
Published: April 2019

The article describes a method for constructing a nonlinear finite-horizon tracking control for the output of a weakly nonlinear dynamic system obtained by the author earlier and also presents the results of numerical experiments, which have used this method to control the output of the longitudinal dynamics model of a vertical takeoff and landing aircraft. The article aim is to demonstrate a performance capability of the method for non-weakly non-linear systems, as well as to evaluate the effectiveness of the obtained control in comparison with linear analogues.

The method is based on the approximate solution of a matrix Riccati-like differential equation with state dependent coefficients. In the English literature, such a constructing approach to control is called a SDRE technique. The latter has become quite widespread in practical applications due to the relative ease of implementation. The disadvantage of the SDRE technique is that there is the need to numerically solve the Riccati-like matrix equation in the course of operation for each new system state, which may come up against the limited computational resources. To overcome this drawback, a number of methods for approximate solution of this equation were developed, including that of for the finite-horizon tracking problem.

A feature of the method under study is an approach to the approximate equation solution based on the formal asymptotic small- parameter expansion of this solution in case of system nonlinearity. A numerical-analytical procedure for constructing the control was obtained. In contrast to the known results, with such an approach there is no need to perform a number of computationally expensive operations in the control process. This allows potential application of this method for problems with highly limited computational resources, for example for the problem of an autonomous robotic control.

The article considers several scenarios where initial conditions of the aircraft dynamics model differ from each other. It is shown that in most cases, the obtained nonlinear controls exceed the linear analogues by the quadratic quality criterion considered.

Paisaje, transformaciones y sociedad: la zona de Boca de las Sierras, Azúl, Pcia. de Buenos Aires (Argentina)
Authors: Degele Pamela Esther
Published: April 2019

Este trabajo se propone reflexionar sobre los factores sociales que influyen en diferentes tipos de intervenciones humanas del espacio a partir de presentar el análisis de un caso actual: paisaje Boca de las Sierras (Azul, Pcia. de Buenos Aires). Dicho paisaje, correspondiente a la zona serrana de Tandilia, ha sido relevante para los grupos humanos desde hace por lo menos 10.000 años constituyéndose, actualmente, en un palimpsesto que incluye actores, valoraciones y estructuras de diferentes épocas. Mediante un estudio cuali-cuantitativo se indagaron las razones por las que prosperaron proyectos de transformación del espacio antes que el de una Reserva Natural que lo conservara. Se obtuvo que la capacidad de la materialidad para influir las percepciones sociales, así como las negociaciones entre diferentes grupos con poder político, económico o simbólico son la clave para su explicación. El arqueólogo, al situarse en dicho contexto, amplía sus posibilidades para comprender la construcción del paisaje cultural como para intervenir en su gestión.

Teaching Grammar: Degrees of Adjective Comparisons in Secondary School of Indonesian Context
Authors: Muflihun Muflihun
Published: April 2019

This article explores the teaching grammar in secondary school in Indonesian context, the writer noticed that most of the students were struggling to clearly understand and unable to use comparison of adjective. Therefore, the writer would clearly explain those problems supported by research findings from previous studies. There are several activities to be used in teaching grammar, which surely could also be adapted to teaching adjective comparisons. However, in this essay, the writer would only address two common activities; namely grammar games and discovering grammar. It can be concluded that teaching grammar to some extent would not be complicated if it is delivered though appropriate teaching methods and deeply understand students’ problems. Numerous engaging activities to teach grammar is available and this would shift our common paradigm of seeing learning and teaching grammar as a passive and ‘old’ fashioned thing to more communicative grammar teaching and learning.

Abstract:    It is undeniable that motivation plays a very important role in the learning process of students. However, some learners still face difficulties in learning English language due to some factors such as differences on its cultural aspects that contributes to the lack of intercultural competence on EFL learners. The aim of the research is to investigate the socio cultural and educational factors that influence the learner’s motivation on English as a Foreign Language (EFL) learning among post-graduate students of English Department of Syiah Kuala University, Aceh, Indonesia. The method of the study is descriptive qualitative where researchers collected the data through library research and distribution of questionnaires to twenty students. The results showed that socio cultural and educational background impact on learners’ motivation in EFL learning. Students who are in collectivistic culture (60%) carried traditional thinking in facing new culture during the EFL learning process while the rest of the students who are in the part of individualistic culture (40%) tend to react positively in facing new culture. Furthermore, educational background also has impacted the learners’ motivation. Students’ prior knowledge contribute to (70%) their learning achievement

Published: April 2019

The main goal of the study was to evaluate the impact of different roller skiing techniques (classical CT and skating ST) performed under field conditions on physical capacity variables in cross-country skiers. The second purpose was to evaluate the possibility to use the test results conducted under field and laboratory conditions interchangeably to determine training loads. Eight international-level cross-country skiers (4 male, 4 female) with 8.8 ± 1.3 years of skiing experience took part in the study. The athletes performed three graded tests to exhaustion: two under field conditions (roller skiing CT and ST techniques) and one in the laboratory: treadmill running (TR). All tests were conducted within a period of two weeks to compare general and specific physical capacity outcomes. ANOVA demonstrated significant differences in the threshold heart rate (HRAT4) (ST 175.3 ± 10.8 bpm, CT 175.8 ± 10.9 bpm, TR 181.5 ± 11.1 bpm; p = 0.004), maximal oxygen uptake (VO2max) (ST 64.0 ± 4.65 ml/kg/min, CT 61.5 ± 5.09 ml/kg/min, TR 65.9 ± 2.30 ml/kg/min; p = 0.008) and maximal HR (ST 189.3 ± 10.9 bpm, CT 188.9 ± 10.6 bpm, TR 199.5 ± 10.3 bpm; p = 0.002). No significant differences were observed between classical and skating roller skiing techniques for maximal and threshold values except for threshold velocity (CT 13.4 ± 1.11 km/h vs. ST 14.7 ± 1.17 km/h p = 0.002). Maximal velocity was not measured. The main finding of the study is that it is possible to use threshold HR values obtained in roller skiing tests performed using the classical or skating techniques interchangeably to determine roller skiing training loads. The results of the study indicate that there is a need to verify maximal treadmill running exertion variables in specific roller skiing tests.
The Evolution of Habitat in Middle Hallstatt on The Territory of Romania
Authors: Olaru Ioana-Iulia
Published: April 2019

The paper will refer only to one of period of Hallstatt, Middle Hallstatt, an important period of the first Iron Age – that form with Late Hallstatt a unity called by historian the protohistory of the Dacians – bringing important transformations recorded in the human beings’ habitat. The settlements and buildings of the entire Bronze Age reflect the continuation of migrations, though limited, by their sedentarization, but also the fortification of some settlements which became real centres of unions of tribes. The characteristic to the mentioned period is continuity (and then the ending) of the process of unification of the Thracian tribes, a process began in Early Hallstatt. The collision of tribes needed the amplification of settlements, but also of the fortifications and also, step by step, the extending of the Greek urbanism implemented in today’s Dobrogea by the Greeks who started colonies here, the Scythian-Greek incluences are to be found in the Late Hallstatt and in other areas on the nowadays territory of our country. The specificity of settlements and buildings of the cultures from the beginning of Hallstatt on the territory of our country will be studied in their evolution towards the next phase – of the second period of the Iron Age: Latène.

History and Modernity in Artistic Education from Romania
Authors: Paşca Eugenia Maria
Published: April 2019

The issue of artistic education is not new, it is still concerned and concerned by many specialists. The newities emerged and imposed from time to time in the evolution of culture and education were and are determined by the scientific and artistic achievements, the enrichment of the possibilities of knowledge and valorization of the experiences and achievements, both from the field of artistic didactics, as well as from musical creation and interpretative art. The perspectives, especially in the last half century, aimed at increasing the knowledge of the child’s physical and mental peculiarities, his ability to form audiences, visions and chinestecs, and the fundamental aims pursued by specialists - teachers and researchers - have been and have continued to improve the contributions of music, literature and dance to the aesthetic and ethical education of children, to developing their sensitivity and intelligence, in other words, to the formation and harmonious development of the children’s personality. From the perspective of knowing and preserving the national identity, in the non-formal educational system existing in Romania, there are musical-literarychoreographic circles with folkloric specifics organized in the Children’s Clubs and Palaces. Also, through school curriculum (CDS), there are initiatives by music education teachers to capitalize on music-literary-choreographic folklore through new disciplines, giving pupils the knowledge of local, regional and national traditions.
How do Topics Emerge in Planning Studies?
Authors: Gravert Andreas , Günzel Marian , Wiechmann Thorsten
Published: April 2019

To which topics planning studies attach attention is subject to dynamic change. Issues such as sustainability, socially integrative cities or metropolitan regions played prominent roles at different times. Against this background, it is noteworthy that within planning studies so far only few studies focus on the fundamental question of why certain topics arise at a certain time in planning research and later subside again. There are no models that could explain why a planning topic receives particular attention. While there is no doubt that topics as those mentioned above are fundamental for planning thought, we cannot explain the timing and causation of their emergence on top of the agenda. This article explores the question of how attention is constituted and developed for a topic in planning studies. Building on political science and communication sociology approaches, an issue-attention cycle is conceptualized as the socially determined development process of an issue. Using the cases of 'climate change' and 'shrinking cities', issue-attention cycles in planning studies are examined exemplarily on the basis of a phase heuristic. Taking a sociology of science perspective, orientations of actions by planning scholars are revealed. A network analysis identifies and explores key actors, their publications, and crucial events for the development of both topics. In addition, a lexicometric discourse analysis examines contents and conceptual contexts. Finally, a qualitative survey explores how and why scientists pick certain topics as part of their individual research biographies. The article concludes with a plea to consider issue-attention cycles as an integral part of planning studies since they strongly affect the prioritization of problems, aims and policies within the scientific realm and beyond.

Authors: Borlea Sorin Nicolae , Achim Monica Violeta , Rus Alexandra Ioana Daniela
Published: April 2019

This research comes to empirical investigate whether the country‟s levels of corruption may be explained by some behavioral factors such as culture, tax morale, trust, religion or happiness. For this purpose, a cross-countries survey of 148 countries is used. The findings document that power distance, trust in legal system, happiness and religion are the most important behavioral determinants of the corruption, explaining about 50 % from the level of corruption around the world. A higher power distance, a lower level of trust in legal system, a lower level of happiness (measured by subjective well-being) and a higher level of religiosity conduct to a higher level of corruption. The findings are important for the policy-makers in order to include the non-economic factors in the analysis of corruption behavior of the people belong to a country, and thus to adopt the most appropriate decisions to fight against this phenomenon.

Authors: Costa Emília Quelhas , Santos Baptista J. , Carvalho Jorge Cabral , Costa José Torres
Published: April 2019

Even in sedentary activities, the workload is justifying more accurate studies about its impact on human beings mainly when related to different temperature and humidity conditions. One of these impacts is related to mental activity, which can be studied by the amplitude of Alpha and Beta waves. This study aims to evaluate brain activity in the occipital lobe from the amplitude of the EEG signal (Alpha and Beta waves) and to relate it to different conditions of temperature and relative humidity (RH) in sedentary tasks. Tests were performed under four different conditions (22°C-40%RH, 22°C-80%RH, 32°C-40%RH and 32°C, 80%RH) with 30 volunteers from which 15 were validated. Results suggest that both temperature and humidity influence the amplitude of the EEG signal (Alpha and Beta waves) in both hemispheres. The greatest amplitudes were found whenever environmental temperature and/or relative humidity values were higher. The results are in agreement with other authors.

Published: April 2019

This study investigated occupational risks associated with roadside vulcanizers in Ife Central Local Government Area, Southwestern Nigeria. The objectives of the study included the determination of spatial distribution pattern of vulcanizers, examination of location factors as well as the assessment of risks that vulcanizers were exposed to. High resolution imagery (IKONOS) was downloaded and roads of interest were extracted from the imagery to produce a map of the distribution of vulcanizers. Nearest Neighbour Analysis was carried out to determine the spatial pattern of distribution of vulcanizers in the study are. Factor analysis was carried out to extract most manageable factors of location choice, other descriptive statistics were conducted to determine risks factors that vulcanizers were exposed to in the study area. Results revealed that vulcanizers were distributed in a dispersed pattern in the study area given the NNI of 3.489. Also, proximity to traffic, distance from home, nearness to motor park, low competition, high traffic volume and opportunity for shelter were extracted factors which contributed a total of 61.314% of variance explained by the variables.  However, traffic noise, exposure to weather condition and dust and smoke formed the major risks that vulcanizers were exposed to in the study area.  The study concluded that most roadside vulcanizers were exposed to risks and actions be taken to relocate them from roadside to reduce mortality that may arise from unsafe trade location.

Assessing the Organisational Capablities of Youth-Serving NGOs in the Context of Youth Poverty Alleviation in Nigeria
Authors: Igbinakhase Idahosa , Naidoo Vannie
Published: April 2019

The purpose of the study that was conducted was to investigate the organisational capabilities of youth-serving non-governmental organisations in the context of youth poverty alleviation in Nigeria. In this article it is argued that the improved capabilities of these organisations play an important role in reducing youth poverty and its negative consequences in Nigeria. In view of the fact that these organisations are experiencing difficulties in reducing youth poverty in that country due to various challenges relating to organisational capabilities, this study aimed to provide insights into the assessment of these organisationsâ€™ capabilities. Data was obtained from a random sample of 187 managers of youth-serving non-governmental organisations and was analysed using a t-test analysis. The theoretical framework for this study was the adapted SCALERS model. The results revealed that the organisations investigated had been able to meet their staffing, communication; alliance-building, replication and stimulating market forces needs effectively. However, it was found that some of the NGOs investigated did not have long-term donors and sponsors that were major sources of income for the organisations and that others had not been successful at attracting government agencies and officials to provide financial support for its efforts. This article argues that the effective management of the organisational capabilities of youth-serving non-governmental organisations could contribute positively to the reduction of youth poverty in Nigeria. This study contributes to research on non-governmental organisations that focus on youth poverty and also to the use of the SCALERS model by re-contextualising it to assess the organisational capabilities of youth-serving NGOs in Nigeria.
Influence of salinity on the properties of the different HPAM/Al3+systems
Authors: Zhang Lei , Khan Nasir , Pu Chunsheng
Published: April 2019

In order to achieve oil increment and water cut reduction in the heterogeneous oil reservoirs, a conformance control technology by using HPAM/Al3+systems has been widely used due to the low price and environmental friendliness. However, the complex structure and state of high-valent metal ions in brine water can directly affect the properties of the different HPAM/Al3+systems, which may lead to unreasonable applications. Therefore, in order to better utilize the HPAM/Al3+systems, the characteristics of gelation of HPAM and the three types of aluminum citrate under different salinities are systematically studied. Experimental results show that an important reason for the cross-linking reaction of HPAM/Al3+being affected by salinity is that the morphology and structure of the aluminum citrate complex is different under the different salinities. Although the change of characteristics of the reaction time and the cross-linking degree of the three HPAM/Al3+systems are different, the process of the cross-linking reactions of the three HPAM/Al3+systems are the same. Besides, the thermal stability of the HPAM/Al3+gels is weakened with the increasing of salinity regardless of the ratio of citrate ligands to Al3+. According to the matching relationship between salinity and HPAM/Al3+systems, the reaction time can be controlled to achieve the requirements of on-site construction operation for the conformance control of a given heterogeneous oil reservoir.

Administrative regulation measures for foreign trade in the European union (on the example of the Republic of Poland) and in the Eurasian economic union (on the example of the Russian Federation)
Authors: Kardanov V. A. , Kulik V. N.
Published: April 2019

The European Union is the largest trading partner for the Eurasian Economic Union. The multi-integration of the Eurasian Economic Union with foreign countries practically guarantees a positive result. The issues, related with non-tariff measures regulating foreign trade, have been considered in the article. For the countries of the Eurasian Economic Union and the Russian Federation in particular, in the near future, the main task should be step-by-step standardization and elimination of almost all non-tariff barriers to trade, as these values significantly aggravate the counter-trade in goods and services and hinder further integration. And this concerns, above all, the development towards the European Union.

The standard drug for treatment of the neglected disease Schistosomiasis is Praziquantel, and the possible emergence of resistance to this treatment makes the research on novel therapeutic agents necessary and urgent. To this end, the targeting of Schistosoma mansoni epigenetic enzymes, which regulate the parasitic life cycle, emerged as promising approach. Due to strong effects of human Sirtuin inhibitors on parasite survival and reproduction, Schistosoma sirtuins were postulated as potential therapeutic targets. In vitro testing of synthetic substrates of SmSirt2 and kinetic experiments on a myristoylated peptide newly demonstrated lysine long chain deacylation as an intrinsic SmSirt2 activity in addition to the known deacetylation. Focused in vitro screening of the GSK Kinetobox library and structure-activity relationships (SAR) of identified hits, led to the first SmSirt2 inhibitors with activity in the low micromolar range. Several SmSirt2 inhibitors showed potency against both larval schistosomes (viability) and adult worms (pairing, egg laying) in culture without general toxicity to human cancer cells.
