The solution of the problem of free vibrations of a rectangular orthotropic plate by the methods of boundary and finite elements under any boundary conditions. Transformation of the two-dimensional differential equation of free vibrations of an orthotropic rectangular plate to one-dimensional. Determination of the complete system of its fundamental solutions using the numerical-analytical method of boundary elements. Implementation of the algorithm on the example of a specific plate and comparison with the results of finite element analysis in ANSYS. The solution to the problem of natural vibrations of a rectangular orthotropic plate is obtained without any restrictions on the nature of the fixing of its sides. A transcendental frequency equation is obtained whose roots give the full spectrum of natural frequencies. The modeling and calculations of the orthotropic plate by the finite element method are performed. An analysis of the numerical results obtained by the author's method shows a very good convergence with the results of finite element analysis. For a plate with rigid fastening of three sides with a free fourth side, the discrepancy is slightly higher than for a plate with a hinged support along the contour. Under both variants of the boundary conditions, the frequency spectrum calculated by the boundary element method is lower than in the finite element calculations. Analytical expressions of fundamental functions are obtained that correspond to all possible solutions to the differential equation of free oscillations. For the first time, a solution to the problem of free vibrations of a rectangular orthotropic plate is presented by the numerical-analytical method of boundary elements. The results allow us to solve the problem of free vibrations of a rectangular orthotropic plate by two methods under any boundary conditions, including inhomogeneous ones.

The aim of the article is to determine the main aspects of the development of a computer game in the system of audiovisual arts, to describe the chronological stages of the development of the artistic component of the work and the organization forms of the plot sequence of games. In this work, we used the method of artistic and stylistic analysis to identify the main trends in the use of artistic expressiveness, a comparatively descriptive method for analyzing the artistic and expressive solution to computer games. The technical evolution of the gaming environment for determining the stages of development of the components of a computer game is considered, which allows you to clearly define the chronological restrictions for creating works of a certain area of audiovisual art. The analysis of the means of expressiveness of computer games is carried out and it is revealed that the techniques and methods of traditional arts become an important part of the assimilation period, namely: expressiveness of first-person action, directing and musical component of games. These funds together define the unique atmosphere of the work. The directions of the artistic component of computer games are considered: a linear diagram of the sequence of actions, non-linear action and the component of "spontaneity" that form a single artistic environment. The influence of artistic-figurative means on the design of computer games is traced and the general patterns of the development of computer games in an interactive virtual environment are revealed. The results can be used for the development of artistic and expressive components of computer games, which make it possible to create a high-quality product of technological art.

MENJADI GEREJA BAGI PEREMPUAN KORBAN PERDAGANGAN ORANG DARI SEKTOR PEKERJA MIGRAN INDONESIA, Jurnal Mateteou STAKN KUPANG 2017 no 5.
Authors: Wetangterah Liliya
Published: February 2020

Sejak tahun 2014, Nusa Tenggara Timur telah dinyatakan sebagai Darurat Perdagangan Orang. Korban perdagangan orang terbanyak berasal dari sektor Tenaga Kerja Indonesia (TKI) dan pekerja migran di dalam negeri. TKI dari NTT di dominasi oleh pekerja perempuan yang bekerja di sektor informal sebagai pekerja rumah tangga. Tingginya angka perempuan korban perdagangan dan TKI perempuan asal NTT sangat dipengaruhi oleh budaya patriakhi. Dalam budaya patriakhi, seorang perempuan akan bertumbuh menjadi perempuan yang tangguh bekerja pekerjaan rumah dan patuh. Pekerja perempuan seperti ini menjadi rebutan di luar daerah dan luar negeri sebab bersedia bekerja apa saja dan patuh pada majikan serta bersedia dibayar murah. Di tengah konteks seperti ini gereja harus merumuskan kembali misinya dalam konteks NTT yang tinggi dengan angka korban perdagangan orang. Misi gereja hendaknya menjadi misi yang memampukan gereja berteologi dengan mendengarkan para korban. Suara dan cerita para korban akan membantu gereja untuk memahami dengan benar perdagangan orang sehingga mampu melawan stigma yang berkembang tentang para TKI. Saat gereja memahami dengan baik perdagangan orang maka gereka akan dimampukan untuk merancang program dan kegiatan-kegiatan yang menjawab kebutuhan korban. Salah satu diantaranya adalah dengan memerhatikan dengan serius ibadah dan program dari komisi perempuan. Komisi ini dapat menjadi ruang dalam gereja untuk melakukan tindakan pencegahan hingga reintegrasi korban.

Adaptive Event Triggering Normed Observer Control of Nonlinear Time Delayed Systems
Authors: Asadbeigi ayyob
Published: February 2020

In this paper, event-triggering state-norm estimators are studied for nonlinear delayed systems also normed-observability concept is extended for these systems. Moreover, we established a Lyapunov–Krasovskii functional to obtain normed observability of the delayed nonlinear systems. Furthermore, an adaptive observer is developed such that convergence of the error system is guaranteed. The proposed event-triggering algorithm yields an event-based observer that ensures uniform ultimate boundedness of the tracking error.

Authors: IJSB
Published: February 2020

Adoption of organic vegetable farming can play a significant role in sustainable agricultural development through refraining indiscriminate use of agrochemicals which has been proven as the significant cause of environmental pollution. In this line, the main purpose of the study was to determine the adoption extent of organic vegetable farming by the farmers of Bogra district and to explore the factors that influence farmers’ adoption of organic farming. The study was conducted in some selected villages under Shahjanpur Upazila (sub-district) of Bogra district. Data were collected by using an interview schedule from randomly selected 102 farmers during whole February, 2017. Multiple regression analysis was done to explore the significant factors and their contribution in adopting organic vegetable cultivation. The survey revealed that highest proportion of the farmers (79.40%) had low to medium adoption of organic farming while the rest had high adoption. Among the selected factors, extension media contact, training exposure, attitude towards organic farming and profitability had a significant contribution to the adoption of organic vegetable farming. The findings of the study indicated that the adoption level of organic vegetable farming has yet not to be satisfactory. Some initiatives like to increase farmers contact with media, arrange more training program, ensure the proper price of organic vegetable and improve transportation should be taken in creating a favorable attitude of the farmers towards organic farming as well as the adoption of organic farming.

Protecting the North Sea: Cleaver Bank.
Authors: Oceana  , Álvarez Helena , Perry Allison L. , Blanco Jorge , Petersen Cecilie , Aguilar Ricardo
Published: February 2020

Cleaver Bank represents the largest area of hard substrate in the Dutch North Sea, and its biodiversity importance has been repeatedly recognised. The combination of oceanographic and geological patterns found in the area (e.g., depth, low currents and light penetration) makes Cleaver Bank a unique enclave of marine life in the Dutch EEZ. Thus, it has already been designated under various figures of protection (see Box 4). However, current management measures for these areas fail to secure the preservation of the area’s fragile combination of features. Bearing in mind that the disappearance of the former rocky banks in Dutch waters was caused by their direct removal in bottom trawls, and the threat that fishing activities pose to the fragile and varied seabed of Cleaver Bank, Oceana proposes that the entire area of Klaverbank SAC should be closed to all type of bottom-contacting gears. Continued bottom-contact fishing in Klaverbankrepresents a clear threat to the fragile benthic ecosystems found in the area. On the UK side, Oceana’s findings have further confirmed that Cleaver Bank as a whole (both the Dutch and UK sides) is characterised by very similar habitats and communities. Oceana urges the UK government to carry out more detailed habitat mapping, in order to better identify the range of features present, and determine which conservation and management measures are needed to preserve and restore the ecological integrity of Cleaver Bank.

When the children do not sleep: the association with paternal mental health
Authors: Bisdounis Lampros , Zouharova Veronika , Hatton Rosie , Gardani Maria
Published: February 2020

Background: The relationship between children’s sleep and paternal mental health has been neglected in the literature. This is in spite of robust relationships being observed in mothers, and despite increasing involvement of fathers in childcare.Aims: The aim of this study was to investigate the relationship between children’s sleep and fathers’ mental health and childcare involvement.Methods: Using a cross-sectional design, 308 dyads of fathers and children were recruited. Fathers completed measures of their children’s sleep, and reported on their own sleep, mental health and involvement in childcare. Initially these items served as correlation variables and in a subsequent analytic step they were introduced in a network of partial correlations together with further sleep and demographic information, controlled by an extended Bayesian information criterion.Results: Initially, significant positive correlations were retrieved between children’s sleep quality and paternal depression, stress and anxiety, but not with fathers’ involvement. In the networks, children’s sleep quality and duration were found to be related to parental availability and involvement respectively, whereas paternal depression was only related to current sleep problems experienced by the fathers. These effects prevailed even after excluding fathers and children with a mental and/or physical health diagnoses.Conclusions: Our findings highlight the importance of including fathers in paediatric sleep research, and the need to incorporate more sophisticated analyses, such as network modelling, to understand the nuanced dynamics of family functioning and its association with children’s sleep.
How do recall requirements affect decision-making in free recall initiation? A linear ballistic accumulator approach
Authors: Osth Adam F , Reed Aimee , Farrell Simon
Published: February 2020

Models of free recall describe free recall initiation as a decision-making process in which items compete to be retrieved. Recently, Osth and Farrell (2019) applied evidence accumulation models to complete RT distributions and serial positions of participants' first recalls in free recall which resulted in some novel conclusions about primacy and recency effects. Specifically, the results of the modeling favored an account in which primacy was due to reinstatement of the start-of-the-list and recency was found to be exponential in shape. In this work, we examine what happens when participants are given alternative recall instructions. Prior work has demonstrated weaker primacy and greater recency when fewer items are required to report \cite{WardTan19}, and a key question is whether this change in instructions qualitatively changes the nature of the recall process, or merely changes the parameters of the recall competition. We conducted an experiment where participants studied 6 or 12 item lists and were post-cued as to whether to retrieve a single item, or as many items as possible. Subsequently, we applied LBA models with various assumptions about primacy and recency, implemented using hierarchical Bayesian techniques. While greater recency was observed when only one item was required for output, the model selection did not suggest there were qualitative differences between the two conditions. Specifically, start-of-list reinstatement and exponential recency functions were favored in both conditions.
Human fear conditioning depends on stimulus contingency instructions
Authors: Mertens Gaëtan , Boddez Yannick , Krypotos Angelos-Miltiadis , Engelhard Iris
Published: February 2020

Human fear conditioning is often seen as the result of a highly automatic process that is independent of higher cognitive functions and verbal instructions. However, cumulative research findings call this view into question. In the current preregistered study (N = 102), we investigated whether the number of participants who successfully show conditioned fear acquisition depends on the instructions given to them before the fear conditioning phase. Particularly, one third of the participants were instructed about the precise contingency between the conditioned stimulus (CS) and unconditioned stimulus (US). Another third was merely instructed that there would be a contingency. The last third did not get any instructions about the CS-US contingency. We found facilitated fear acquisition rate in the first and second group compared to the third group. Furthermore, contingency reversal instructions following the acquisition phase reversed both conditioned skin conductance and startle responses. These results highlight that researchers should systematically report the instructions given to participants in human fear conditioning studies.
High emotion differentiation buffers against internalizing symptoms following exposure to stressful life events in adolescence: An intensive longitudinal study
Authors: Nook Erik C , Flournoy John Coleman , Rodman Alexandra M , Mair Patrick , McLaughlin Katie A
Published: February 2020

Exposure to stressful life events is strongly associated with internalizing psychopathology, and identifying factors that reduce vulnerability to stress-related internalizing problems is critical for development of early interventions. Drawing on research from affective science, we tested whether high emotion differentiation—the ability to specifically identify one’s feelings—buffers adolescents from developing internalizing symptoms when exposed to stress. Thirty adolescents completed a laboratory measure of emotion differentiation before an intensive year-long longitudinal study in which exposure to stress and internalizing problems were assessed at both the moment-level (n=4,921 experience sampling assessments) and monthly-level (n=355 monthly assessments). High negative and positive emotion differentiation attenuated moment-level coupling between perceived stress and feelings of depression, and high negative emotion differentiation eliminated monthly-level associations between stressful life events and anxiety symptoms. These results suggest that high emotion differentiation buffers adolescents against anxiety and depression in the face of stress, perhaps by facilitating adaptive emotion regulation.

Community settlements in a city have a very important role in providing services in the field of life. Increasing the population in a strategic land in urban areas will cause urban problems, especially population density, building irregularities and slums. This increase in population is due to economic, legal, social and cultural aspects, all centered in the city so that many rural communities flock to the city to improve their economy. Seberang Palinggam Sub-District, South Padang District, Padang City is one of a strategic location because it is close to the port, trade and service area. This strategic location caused many people who settled there. As a result, Seberang Palinggam Village is included in 23 slum areas in Padang City, based on Padang Mayor Decree No. 163 of 2014. This study aims to determine the right direction in the structuring of the slum environment with the Eco-Settlement approach that develops from the concept of sustainable development. The target being developed is to identify the characteristics of slums in villages across Palinggam using the Qualitative Descriptive Method, Analysis of the factors that led to the development of slums using Delphi. From this analysis, it is obtained an outline based on influential factors in the form of adding and improving the quality of sanitation infrastructure, clean water, drainage and healthy houses, increasing the carrying capacity of the environment and community resources, empowering the community's economy, and improving the quality of institutions and awareness of existing policies related to slum environment management.

Both nations can draw strength from the diversity that prevails irrespective of uneven size, power potential, historical complexes and different speed in the development. This paper also tries to address the gap in the academic arguments regarding the conceptualization, essence, and practicability of citizen diplomacy in foreign policy processes and explores multiple micro-level themes and actors enhancing citizen diplomacy through the tourism industry in the context of Nepal-China relationships. Based on the aforementioned scene, the researcher situates the experience as an exchange fellow student, vis-à-vis tourism and the peace-through-tourism idea and mention ways of people-to-people engagement for multiple stakeholders.

What is the present state of democracy among the Asian countries that were (re)democratized during the third wave of democratization? What makes the differences? Why some specific factors play prominent role on the deepening of democracy among them? These are the primary questions of this study. The findings from ten young Asian democracies are as follows. First, all the Asian countries that (re)democratized during the third wave of democratization are practicing democratic system at present. Six of them experienced the breakdowns, while four remain as a continuous democracy. Second, out of eleven structural and institutional factors, examined in this research, only the presidential system has clearer positive impact and economic development has a partial effect on the deepening of democracy. Indirect dictatorship or dominancy of family politics in the parliamentary democracies is found as main reason for the perils of parliamentarism among young Asian democracies.

Early corrosion stage of welded carbon steel joints in CO2-saturated oilfield water

Published: February 2020

The early corrosion stage of carbon steel welded joints in water occurring in a CO2-saturated oilfield was investigated. Electron backscatter diffraction (EBSD) and energy dispersive X-ray spectrometry (EDS) were used to characterize the microstructure and chemical composition distribution of the different zones in the welded joint. Atomic force microscopy (AFM) and a VEECO optical profiler were used to observe the sample surface corrosion morphology at different immersion times. The results show that the early stage corrosion characteristics of each zone in the welded joint are related to grain orientation and not related to grain size, grain boundary type, or to the second phase. Additionally, it was found that chemical composition distribution is the primary reason for the differences in the early stage corrosion characteristics observed for each zone in the welded joints.
An algebraic-analytic model for the characterization of the frequency domain of photodiodes

A design and principle of silicon photodiodes (PD) operation in the frequency domain are presented. To further enhance the signal-to-noise ratio, a methodology is proposed regarding how to cut down the response in the frequency domain between the time constant and stability characteristics. An algebraic-analytic model is developed to obtain the frequency behavior of the PD which are used as semiconductor devices to capture optical modulated light. The proposed model consists of connecting the anode and cathode terminals of a PD, an operational amplifier (AOP) for performing a control over the frequency domain optical device. The basic idea consists in analyzing the response of the PD at different frequencies using Bode, Nyquist and Black diagrams which have been obtained by a transfer function in the frequency domain when the optical response is attenuated. Consequently, a cutoff frequency to be determined by a test signal, and thus allowing for a certain range of frequency capture for operation and application of the PD. This paper highlights several key issues in the measurement methods on frequency domain of the Si PD. In some cases, indirect signal metering of modulated light presents unwanted signals. Consequently, the RC filter responses they are frequency filtering effect. Therefore, for the improved PD measurements, might be necessary the solution in the frequency domain for transfer function and theoretical-experimental relationship on materials testing. The results show that this system has the capacity to acquire the operating range in the frequency domain and thereby calculate the cutoff frequency through the solution of the real and imaginary part of the PD-AOP transfer function model.

In the current environment, aluminum metal matrix composites are in enormous demand due to notable improvement in mechanical and wear characteristics. Several manufacturing techniques have been developed among which traditional stir casting is preferred due to simple processing techniques other than available methods like compocasting, in situ fabrication, powder metallurgy or friction stir processing. Nanoparticles seem appealing to researchers for manufacturing nanocomposites due to their improved microstructural, mechanical and tribological properties. Parameters like weight or volume fraction, stirrer design, number of blades, stirring speed, stirring time, reinforcement feed rate and melting temperature required to prepare a composite are discussed in great detail. The innovation of this assessment effort lie in the fact that few such review works have been published for the stircasting technique to prepare aluminum metal matrix composites/nano composites reinforced with SiC, TiO2, Al2O3, B4C and TiC.

The need for electricity has increased every year. One of the most popular supply of electrical energy is electrical energy from energy sources flowing and plunging water, called as the Micro Hydro Power Plant (PLTMH). Cisadane River is one of the major rivers with length around 80 kilometers and crosses 44 districts in 5 regencies / cities, including desa Kranggan, South Tangerang. Therefore, community service is carried out in an effort to utilize and optimize the flow of the Cisadane river. The Study of PLTMH design for community service program was conducted. Data of river flow, altitude and location of the river flow will be collected so that it can be calculated and observed for the design of PLTMH that best suits the efficiency of the largest electrical energy, which is obtained using the TurbinPro software program. PLTMH planning chose to use a propeller/kaplan turbine because of its low head which is 4 meters. The power generated is 994 kW at a maximum head with an efficiency of 91.2% and a river flow of 52.26 m3/s and at a minimum head of 601 kW with an efficiency of 82.2% and a discharge of 47.56 m3/s. Keywords: electrical energy, community service program, PLTMH, power generation, Kaplan turbine
