DEVELOPMENT AND VALIDATION OF QUESTIONNAIRE ON SERVICE QUALITY AND PATIENTS SATISFACTION IN HOSPITALS
Authors: Dubey Pushkar , Pandey Deepak
Published: May 2019

Background:
Service quality is an important dimension for examining value of hospitals.
Satisfaction of patients from the available service quality determines the
overall value of a hospital. The increasing emphasis of services in hospitals
and patients satisfaction has called for providing improved service which
yields more satisfaction. Aims &
Objectives: The aim of the study was
to develop and validate a questionnaire that measures service quality and
patients satisfaction in hospitals. Material
& Methods: A self structured questionnaire containing 29 items was
initially developed and was subjected to scrutiny by the experts to access the
content validity of the questionnaire. A total of 200 patients responded to the
service quality and satisfaction scale. The reliability of the scale was
determined by Coefficient of Cronbach’s α.
Exploratory factor analysis was used to test the validity of the scale
and further the hypothetical model was evaluated by structural equation modelling
for adequacy of goodness-of-fit to sample data. Result: The resultant outcome showed that the proposed model was a
good fit. Conclusion: The result
concludes that the conceptualised domain of service quality and patients
satisfaction could be measured successfully through the use of the 18 item
instrument developed in this study.

A Grounded Theory on Conflict Management in Long-Distance Relationships
Authors: Naz Gremil Alessandro
Published: May 2019

The literature on interpersonal conflict management is already extensive and theories have been forwarded since the 1960s. However, these theories were created with proximal couples in mind. They do not address the situation of partners in long-distance relationships (LDRs). Thus, a grounded theory study was done among 10 Filipinos in LDRs. They were individually interviewed for about an hour per session and the interviews were transcribed. The transcriptions were then subjected to open coding, which yielded 18 open codes. During the selective coding, these were pared down to five categories. Their relationships were identified during the theoretical coding, which resulted in a grounded theory on conflict management in LDRs. This theory posits that the reason for the LDR; long-term relationship plans; communication practices; and the values, behaviors, and other attributes of the couple all shape long-distance conflicts. The computer-mediated communication technologies used by the long-distance couples were factors in relational maintenance.

Authors: Musfiroh Maryam
Published: May 2019

Pendidikan karakter telah menjadi wacana yang hangat dibicarakan oleh para pakar pendidikan. Pasalnya, kasus-kasus moral yang sering terjadi pada beberapa siswa sekolah menengah pertama, khususnya di kota Bandung, disebabkan oleh pendidikan yang hanya menekankan pada aspek kognitif saja dengan mengabaikan penanaman karakter di dalamnya. Penelitian kualitatif dengan metode survey crossectional terhadap 40 siswa SMP kelas 9 di Kota Bandung telah memberikan suatu pola hubungan antara tipe kecerdasan siswa berdasarkan angket identifikasi kecerdasan majemuk yang diadaptasi dari model Howard Gardner dengan karakter siswa yang diukur melalui Tes Dilema Moral pada kasus gunung meletus. Pola tersebut menghasilkan siswa dengan kecerdasan Verbal-Linguistik; Logis-Matematis memiliki karakter tinggi pada Moral-Knowing. Siswa dengan kecerdasan Visual-Spasial; Musikal; dan Intrapersonal memiliki karakter tinggi pada Moral-Feeling. Sedangkan untuk Moral-Action, tingkatan tertinggi dimiliki oleh kelompok siswa dengan kecerdasan Kinestetik; Interpersonal; dan Naturalis.

Northern Shelf Bioregion Climate Change Assessment: Projected climate changes, sectoral impacts, and recommendations for adaptation strategies across the Canadian North Pacific Coast
Authors: Whitney Charlotte , Conger Tugce
Published: May 2019

Planning for adaptation to climate change requires regionally-relevant information on rising air and ocean temperatures, sea levels, increasingly frequent and intense storms, and other climate-related impacts. However, in many regions there are limited focused reviews of the climate impacts, risks, and potential adaptation strategies for coastal marine areas and sectors. We report on a regional assessment of climate change impacts and recommendations for adaptation strategies in the NE Pacific (British Columbia, Canada), conducted in collaboration with a regional planning organization (Marine Plan Partnership), aimed at bridging the gaps between climate science and regional adaptation planning. We incorporated both social and ecological aspects of climate change impacts and adaptations, and the feedback mechanisms which may result in both increased risks and opportunities for the following sectors: ‘Ecosystems’, ‘Fisheries and Aquaculture’, ‘Communities’, and ‘Marine Infrastructure’. Climate change impacts are already evident across the region, and over the coming decades air and ocean temperatures will continue to rise, along with sea levels, ocean acidification, ocean deoxygenation, and the frequency and intensity of extreme weather events. As next steps for communicating the results within the region, which is currently undergoing a participatory coastal marine planning process, we propose proactive planning measures including communication of the key impacts and projections and cross-sectoral assessments of climate vulnerability and risk to direct decision making.
Information Leakage in the Response Time‐Based Concealed Information Test
Authors: Lukács Gáspár , Ansorge Ulrich
Published: May 2019

The Response Time‐Based Concealed Information Test (RT‐CIT) can reveal when a person recognizes a relevant (probe) item among other, irrelevant items, based on comparatively slower responses to the probe item. For example, if a person is concealing his or her true identity, one can use the suspected identity details as probes, and other, random details as irrelevants. However, in our study, we show that even when participants are merely informed about such probes (i.e., the relevant identity details) before performing the RT‐CIT, their responses will also be slower to these details. Hence, it is more difficult to distinguish such innocent but pre‐informed persons from actually guilty persons. At the same time, we introduce a CIT version with familiarity‐related inducer stimuli, but with no targets, that elicits probe‐minus‐irrelevant RT differences only among guilty participants but not among informed innocent participants. Implications for the theory and the application of CITs are discussed.
Data Is the New What? Popular Metaphors & Professional Ethics in Emerging Data Culture
Authors: Stark Luke , Hoffmann Anna Lauren
Published: May 2019

A growing list of high-profile controversies involving the social impacts of artificial intelligence systems (AI), digital data collection and algorithmic analysis have forced difficult conversations around the ethics of data-intensive digital technologies and so-called "big data" research. These incidents are directly relevant to newly coalescing cultures of "data science," an emergent field which seeks both to interpret and capitalize on the creation, collection, and processing of knowledge through large collections of digital data, often in conjunction with particular techniques like machine learning (ML). The long list of recent public controversies, as Brian Beaton observes, lays bare data science's extant lack of direction regarding professional ethics or values.
The Land of Meat and Potatoes? Exploring Ireland’s Vegan and Vegetarian Foodscape
Authors: Wrenn Corey
Published: May 2019

While it would not be accurate to suggest that Ireland is a hub of veganism or vegetarianism, too often it is written off as inherently unsympathetic to the ethics of plant-based eating and anti-speciesist politics. While it is true that Irish culture is historically tied to speciesism and its economy is especially dependent upon “meat” and dairy production, Ireland’s relationship with other animals is complex and sometimes forgiving. This essay seeks to bring shape to the Irish vegan ethic, one that can be traced along its history of animism, agrarianism, ascendency, adaptation, and activism. From its pagan roots to its legacy of vegetarianism, Ireland’s history has been more receptive to Nonhuman Animal interests than might be currently understood. Its contributions to the modern Nonhuman Animal rights movement and developments in green agriculture must also be taken into account. More than a land of “meat” and potatoes, Ireland exists as a relevant, if overlooked, participant in Western vegan thought.
THE DESTINIES OF AFRICANS IN THE MODERN WORLD ARE HINDERED BY SELFISH LEADERS (MATT. 20:24-28)
Authors: Ezeogamba Anthony Ikechukwu
Published: May 2019

Africa as a nation stands out as one of the cradles of life and civilization but whenone looks around today one discovers that Africa has become the dumping ground of usedproducts from Europe and America and to save life, one must travel to get adequate medicalattention. Hospitals, schools, road networks, modern mass communication equipments, jobopportunities, scholarship schemes, electricity are majorly in shambles or epileptic. When onevisits some institutions of higher learning as well as hospitals outside the shores of Africa, onediscovers that experts in various fields working in them are from Africa. One of the thingsmigration of the young from Africa to Europe and America has taught us is that African childrencan compete favourably with their European and American counterparts when placed under thesame condition. Hence, it is not that Africans are not gifted intellectually, they are but African'sintellectual prowess has not been adequately harnessed as a result of the actions and inactions oftheir leaders. This proves that there is nothing wrong with African soil, water, air and vegetation.The problem is actually perpetuated daily by old, selfish, visionless and uncharismatic leaders inAfrica. When such leaders are on seat, the destinies of their citizens are daily suppressedknowingly or unknowingly. This study aims at showing that African underdevelopment lies in thehands of selfish and sit-tight leaders. Jesus in the above chapter and verses of Matthew urges thatanyone who will present himself to be a leader must be the servant of others. The desire of aservant leader centers on how to help all citizens realize their destinies. This study adopted thehistorical critical exegesis as well as library research as her methodology to arrive at herconclusions. This study argues that if present crop of leaders in Africa were to be selfless andcharismatic, Africa will be the envy of the whole world. Significantly, this study will be ofimmense benefit to Africans and indeed the whole world.

Authors: Borysova Ludmila , Borysova Larysa
Published: May 2019

Introduction. In the 21st century tourism took a leading place in the international foreign economic relations, began to have a serious impact on development of economy of the certain countries and the world economy in general. Тhose benefits for both people and economy of countries and the whole regions do not raise any doubts. Tourism is a complex sector, but it significantly influences national economy, social and humanitarian bases.
Aim and tasks. Research objective is definition of the developments’ directions and tourism industry’s financing, identification of factors, regularities and development trends at the present stage in Ukraine. Thus, there was a task to analyze systemically the current state of the Ukrainian tourist industry’s development, in other countries, and to investigate the question concerning financial and organizational component of the Ukrainian tourism industry functioning in Ukraine.
Results. It was offered to use the concept of tourism development with transition in development from short-term to long-term planning, at the international, national and regional levels. Developing of the telecommunications has a certain influence on the development directions of the tourist industry: development of portals, websites, mobile applications to simplify communication between suppliers of tourism and ultimate consumers. In Ukraine, is more effective the state regulation model of tourism with control through the separate divisions in two directions. This will resolve the question of budgetary funds use for development and implementation of tourism’s development programs. It is necessary to use alternative sources of travel business’s financing such as agreements about tourist object’s share uses, as partnership in attraction of borrowed funds and sponsorship.
Conclusions. Аt the present stage the important direction is state regulation in tourism in combination of the state and regional development tourism programs. These regulations requires improvement of tourists’ service quality and personnel’s professional competences development, development of the marketing plan and creation of the Ukrainian tourist agencies on advance in Ukraine and abroad. Such development has to be carried out by taking into account development of an information economy: in the Internet and with use of innovative financial instruments.
Use of Hounsfield units of S1 body to diagnose osteoporosis in patients with lumbar degenerative diseases
Authors: Zou Da , Li Weishi , Xu Fei , Du Guohong
Published: May 2019

OBJECTIVE

The aim of this study was to evaluate the use of Hounsfield unit (HU) values of the S1 body to diagnose osteoporosis in patients with lumbar degenerative diseases.

METHODS

The records of 316 patients of ages ≥ 50 years and requiring surgery for lumbar degenerative diseases were reviewed. The bone mineral density (BMD) of the S1 body and L1 was measured in HU with preoperative lumbar CT. Circular regions of interest (ROIs) were placed on midaxial and midsagittal images of the S1 body. Dual-energy x-ray absorptiometry (DXA) and the criterion of L1 HU ≤ 110 HU were used to diagnose osteoporosis. The area under the receiver operating characteristic curve (AUC) was calculated to assess the use of HUs of the S1 body to diagnose osteoporosis.

RESULTS

The interobserver and intraobserver reliability of measuring HU of the S1 body was excellent with intraclass correlation coefficients over 0.8 (p < 0.001). The correlation between HUs of the S1 body and average T-score of L1–4 was significant with Pearson correlation coefficients ≥ 0.60 (p < 0.001). The AUCs for using HUs of the S1 body to diagnose osteoporosis were 0.86 and 0.88 for axial HU and sagittal HU, respectively (p < 0.001). The HU thresholds with balanced sensitivity and specificity for diagnosing osteoporosis were 202 HU for axial HU (sensitivity: 76%; specificity: 76%) and 185 HU for sagittal HU (sensitivity: 80%; specificity: 80%).

CONCLUSIONS

Both sagittal and axial HUs of the S1 body are useful tools for assessing BMD and diagnosing osteoporosis. Measuring HUs of the S1 body preoperatively from lumbar CT may help with surgical planning for patients with lumbar degenerative diseases.
Press Freedom and the Global State of Democracy Indices
Authors: Noonan Joseph
Published: May 2019

The key findings on press freedom derived from the most recent update to the Global State of Democracy (GSoD) Indices data are as follows: During the period 1975–2017, the world has seen a remarkable improvement in both Freedom of Expression and Media Integrity, as measured in the GSoD Indices. In 1975, 62 per cent of countries had low levels of Freedom of Expression and 63 per cent had low levels of Media Integrity, while in 2017, this was the case for only 16 per cent and 17 per cent of countries respectively. In recent years, an increasing number of countries that were previously high performing on Freedom of Expression and Media Integrity are slipping into the mid-range, reflecting worsening conditions in thesecountries. The share of high-performing countries on Freedom of Expression peaked in 2012, at 41 per cent, before dropping to 34 per cent by 2017. Likewise, the share of high-performing countries on Media Integrity has dropped from 40 per cent in 2006 to 32 per cent in 2017. Since 2012, the number of countries showing a decline in Freedom of Expression has increased steadily every year. The period 2015–2017 marked the first time where more countries have declined than advanced for two consecutive years. Of all the aspects of democracy, Freedom of Expression is the one that has seen the most countries showing a decline. From 2012 to 2017, 24 per cent of countries showed a decline, and only 11 per cent an improvement, in their scores on Freedom of Expression. Declines are seen across all regions of the world, with Europe seeing the most countries decline (14 countries, 33 per cent). Of the 37 countries experiencing 5-year declines, 3 saw declines great enough to fall below the global average (Cameroon, Libya, Turkey), and 8 fell below their respective regional average (Burundi, Cambodia, Croatia, Egypt, Libya, Poland, Thailand and Yemen). From 2012 to 2017, 21 per cent of countries in the world (33 countries) saw a decline on Media Integrity, while only 6.3 per cent (10) saw an improvement. The vast majority saw no change one way or the other. In the countries with declining Media Integrity, 5 saw declines great enough to fall below the global average (Burundi, Egypt, Serbia, Thailand, Turkey), and 6 fell below their respective regional average (Bahrain, Burundi, Egypt, Hungary, Poland, Romania). Looking at both Media Integrity and Freedom of Expression, 20 countries have seen declines over the period 2012–2017 on both measurements (9 in Europe, 4 in Africa, 4 in Asia and the Pacific, and 1 each in Latin America and the Caribbean, Middle East and Iran, and North America), while 7 countries have seen improvements (4 in Africa and 3 in Asia and the Pacific). These developments have affected countries across all regions.

Spor ve Mantık İlişkisi
Authors: ALTUNYA Hülya
Published: May 2019

Spor ve mantık, bedeni
ve zihni disipline eden ve düzenli olarak tatbik edildiğinde her ikisinin de
sağlıklı çalışmasına imkan veren kurallardan ibarettir. Adeta bedeni olumlayan
bir düşünme biçimiyle spor eğitimi, insanın bilgeliğini kazanmasını sağlayan bilgiler
bütününden oluşur. Buna karşılık mantık ise zihnin doğru düşünmesinin garantisini
veren kurallardan teşekkül eder. Antik Yunan’da Platon ve Aristoteles, spor ve mantığın
insan bedeni ve zihni üzerindeki önemi ve değeriyle ilgili olarak görüş
açıklayan ilk filozoflardır. Platon, çocuklara ve gençlere fiziksel
hareketlerin öğretilerek bedenlerin güçlü, sağlıklı ve estetik bakımdan güzel
olmalarını önermektedir. Buna karşılık Aristoteles, mantık biliminin kurucusu
olarak zihinlerin doğru ve ölçülü düşünebilmesinin yolunu inşa eder. Buna göre
kurallarına uyularak tatbik edildiğinde mantık, zihnin hataya düşmesini
engelleyen alet ilmidir. Öte yandan spor, insan bedeni için faydalı olan fiziksel
hareketlerin nasıl yapılması gerektiğini açıklayan ve böylece bedenin ölçülü ve
dengeli bir yapıya sahip olmasını sağlayan bilimdir. Yani zihnin sağlıklı
işleyişinin ölçütü mantık ise sağlıklı bedenin ölçütü de spordur. Farklı kategorilerde
olmakla birlikte birer değer olmaları bakımından beden ve zihin, düşünen/konuşan canlı (hayavanü’n-natık)
şeklinde tanımladığımız insanı oluşturan temel yapıdırlar. Spor ve mantık ise
bu temel yapının formudurlar. Bu araştırmada öncelikle sporun ne’liğini
sorunsallaştırarak mantıksal tahlillerle onun mahiyetini açığa çıkartmayı
deneyeceğiz. Daha sonra mantığın ne’liği üzerinde duracağız. Mantıksal düşünme,
eleştirel düşünme, yaratıcı düşünme, sezgisel düşünme vb. düşünme çeşitleriyle
bağlantılı olarak spor ve mantık arasındaki ilişkiyi tartışmaya çalışacağız.
Practitioner-Suggested Voluntary Psychiatric Hospitalization from a Feminist Therapy Perspective
Authors: Moseley Ashley Elizabeth
Published: May 2019

This study explores “practitioner-suggested voluntary psychiatric hospitalization,” or the gray area between voluntary and involuntary admission into psychiatric inpatient treatment where voluntary patients feel they have been persuaded into admission by practitioners with the authority to admit them involuntarily. Some scholars discuss this phenomenon in terms of power, indicating that what a practitioner views as a suggestion may be interpreted by a patient as coercion due to power imbalance within the psychiatric setting. However, research on how individuals with marginalized identities are affected by practitioner-suggested hospitalization is largely inconclusive. This study sought to address this gap by interviewing four feminist therapists, who focus on the intersections of social identities such as race, gender, and sexual orientation while promoting an egalitarian therapeutic relationship. The study discussed the experiences and opinions of feminist therapists and analyzed emerging themes.
Never Black and White: Representing Black Women in Revolutionary France
Authors: Garcia Danielle
Published: May 2019

My research focused on Marie-Guillemine Benoist’s Portrait d’une Femme Noire, exhibited in the Paris Salon of 1800. This remarkable picture of a free woman of African descent was painted in the decade between the first abolition of slavery in the French colonies in 1794 and Napoleon Bonaparte’s reinstatement of it in 1804. I addressed the question of what we can make of the existing visual and literary representations of black women in this period, and how these representations can be used to understand something of the kind of roles or experiences the women had in French society. In the absence of firsthand accounts of art and writing by black women, I have analyzed the conditions of their existence, ideologies that shaped their experiences, and a varying range of representations of them made by white artists and writers.
The Art-Science Project: Researching the Cross Section between the Visual Arts and Biological Sciences
Authors: Taylor Brett Jeffrey
Published: May 2019

The created portfolio explores the area of academic art and how it can be translated into the fields of fine art and biological science. The sculptural specimens were created to further understand how art is used in scientific exploration today compared to that of antiquity.During the period of enlightenment, science and art were codependent. Studio art was employed as a form of research and communication. In light of this, the thirty-five spider models were created in the Entomology and Nematology Lab at the University of Florida. The works of art encompass a diverse range of species, scales, and functions.  The works were designed to serve three purposes: life size models were printed and painted to serve as decoys for reproductive research; medium scale models were distributed to international geocaches to gage public opinion on arachnids; and large scale models were utilized as educational tools. The range of models serves different functions but they all answer to principles of art. Thus defining the interdisciplinary nature of art as it relates to scientific study.

About 80 percent of the management of tourist attractions in Balikpapan and East Kalimantan are generally managed by local governments while 20 percent are only managed by the private sector. This study aims to determine the quality of tourism management services managed by local governments with the private sector with a case study of the attractions of Manggar and Lamaru beaches. Manggar Beach is managed by Disporapar Balikpapan (public sector), while Lamaru Beach is managed by the private sector (private sector). The hypothesis in this study is that the quality of Lamaru beach services is better than Manggar beach. This study uses a comparative method (comparison) by measuring SERVQUAL dimensions; Tangibles, Reliability, Responsiveness, Assurance, and Empathy with 25 instruments. The instrument used in this study is intended to produce accurate data using a Likert scale. The number of respondents is 150 people who are domestic tourists as long as they have visited the two attractions. As a result, the quality of Lamaru beach services is far better than Manggar beach for all SERVQUAL dimensions

Published: May 2019

Today the noble values of the Pancasila begin to fade because of the growth of fanatical attitudes towards certain groups, the emergence of various kinds of organizations with particular groups even in the name of Islam. Islam which teaches the values of glory such as; love of peace, love, mutual respect between one another religion, but religion is sometimes interpreted according to his will by certain groups as a foundation in launching his mission by approaching religious teachings by means of violence and coercion. Radicalism which was only directed at a less educated group of people, has now fallen to educated groups or students in universities. Some university leaders have indicated the involvement of students in radical understanding on campus. Because of concerns about the emergence of radical understanding in higher education institutions a few months ago the Minister of Technology Research and Higher Education Prof. Dr. Mohammad Nasir gathered college leaders to declare against radicalism the campus. The purpose of this study is to further examine the potential of radicalism among Balikpapan State Polytechnic students, the object of this study is students especially students of internal organizational activists on campus or students of campus external organizational activists data collection techniques using questionnaires and interviews then the data is processed. The results of this study indicate the existence of radicalism among students. From data obtained, radicalism among students is not formed from internal campus but formed through the activities of external organizations that are outside the campus.  The existence of student affiliations with external campus organizations forms students into radicals which then enter the campus.

The analysis of literature data, which showed a decrease fuel consumption and smoke emissions of diesel engines during the combustion of water-fuel emulsions based on diesel fuel, was carried out.The combustion of water- fuel emulsions decreases the intensity of low-temperature pollution, which is explained by significant improvement in the quality of the combustion process as a result of micro explosions emulsion droplets and an increase in the contact surface of fuel vapor with the oxidizer.According to the literature data, the use of water-fuel emulsion does not require constructive alterations of the diesel engine and can significantly improve the environmental characteristics of the engine. Based on the experimental and theoretical studies, the relations of the specific increase in the mass of pollution on the excess air factor for different water content of water-fuel emulsion based on low-viscosity fuels were obtained. For evaluation of the joint effect of three factors on the pollution intensity in the statistical processing of experimental data, the Statgraphics Plus for Windows system, providing access to a full set of statistical methods and providing an opportunity to conduct an extended regression analysis was used. Statistical processing of the research results, which showed the prevailing influence on the specific increase in the mass of pollution of the sulfur and water content in the water-fuel emulsion, and then the excess air factor, was carried out. A three-dimensional model and regression equations that take into account the effect on the value of the specific increase in the mass of pollution of the main parameters are obtained. The contour graphs of the dependences of the specific increase in the mass of pollution on the sulfur content, water content in the water-fuel emulsion and the excess air factor are obtained. Analysis of the research results shows that burning of water-fuel emulsions based on low-viscosity fuels with water content of 30% reduces the level of pollution of heating surfaces by 2,36 times. The obtained relations can be used in the design of condensing heating surfaces

The processes of gas turbine unit inlet air cooling by absorption lithium-bromide chiller utilizing the turbine exhaust gas waste heat as athermotransformer has been analyzed for hour-by-hour changing ambient air temperatures and changeable heat loads on the air cooler as consequence. The computer programs of the firms-producers of heat exchangers were used for gas turbine unit inlet air cooling processes simulation. It is shown that at decreased heat loads on the air cooler an excessive refrigeration capacity of the absorption lithium-bromidechiller exceeding current heat loads is generated which can be used for covering increased heat loads on the air cooler and to reduce the refrigeration capacity of the absorption lithium-bromidechiller applied. To solve this task the refrigeration capacity required for gas turbine unit inlet air cooling is compared with an excessive refrigeration capacity of the absorption lithium-bromidechiller exceeding current heat loads summarized during 10 days of July 2015. The system of gas turbine unit inlet air cooling with a buster stage of precooling air and a base stage of cooling air to the temperature of about 15 °C by absorption lithium-bromide chiller has been proposed. An excessive refrigeration capacity of the absorption chiller generated during decreased heat loads on the gas turbine unit inlet air cooler that is collected in the thermal accumulator is used for gas turbine unit inlet air precooling in a buster stage of air cooler during increased heat loads on the air cooler. The results of gas turbine unit inlet air cooling processes simulation proved the reduction of refrigeration capacity of the absorption lithium-bromide chiller applied by 30-40 % due to the use of a buster stage of precooling air at the expanse of an excessive absorptionchiller refrigeration capacity served in the thermal accumulator. So the conclusion has been made about the efficient use of a buster stage of gas turbine unit inlet air cooler for precooling air by using an excessive refrigeration potential of absorption lithium-bromidechiller coolant saved in the thermal accumulator

Presented are the results of an analysis of the growing interest in the use of low Earth orbits (up to 1500 km high) for the introduction and development of the Internet of things (Internet of Things - IoT). Industrial Internet of things (Industrial Internet of Things-IIoT). Internet of things for remote areas (Remote Internet of Things - RioT, for the purposes of scientific research and economic use of natural resources, control of the development and operation of infrastructure projects, the operation of territorially distributed industrial production, transport infrastructure. Factors significantly limiting the further introduction of micro and nano satellites are given. The authors proposed to resolve this contradiction on the basis of the developed concept of creating the architecture of a "distributed satellite". As an example, the article considers possible applications of the distributed satellite architecture in two segments of the space information systems market: remote sensing of the Earth and telecommunication systems. The application of the "distributed satellite" in radar systems with synthesized aperture (SAR-system) was considered taking into account the requirements of the operators of satellite SAR-systems and consumers of their information. It is shown. that the use of the "distributed satellite" architecture in SAR-systems also makes it possible to realize the technology of multi-static radar with a "soft" interference base (from 200 m to 1 km). The scheme of organization and interaction of the "distributed satellite" in the satellite-transmitter on the platform of the micro satellite, which is the core of the satellite cluster, and several satellites-receivers on the cube-sat platform is presented. The functions performed by the satellite-transmitter, the inter-satellite radio link and the satellite-receiver are considered in detail. The work of the "distributed satellite" is illustrated by the presented structural diagram of the SAR-system for remote sensing of the Earth, a version of the architecture of the low-orbit satellite communication system and the scheme for constructing a satellite system for the provision of IoT services. In conclusion, it is noted that the architecture of the "distributed satellite" makes it possible to effectively use satellites of the class of micro/nano satellite (cube-sat) to create complex space-based information and telecommunication systems

In many practical situations, signals are corrupted by noise and it is desired to apply filtering to remove it. For most of modern filters, it is needed to know noise variance a priori or to pre-estimate it in a blind manner in the presence of signal component. Requirements to methods of blind estimation are formulated and it is shown that it is difficult to satisfy these requirements. Based on the used model of additive white Gaussian model, a method operting in DCT domain is considered and thoroughly studied. The choice of test signals is motivated. Local estimates obtained on blocks of different size are studied and it is demonstrated that these local estimates, although based on robust estimates of data scale, can be sufficiently influence by signal component that leads to a certain percentage of large amplitude DCT coefficients in data sample. It is then shown that such abnormal local estimates have to be rejected (or their influence on the final estimate should be minimized). This is done by robust processing of local estimates. It is established that block size considerably influences accuracy characterized by bias of estimates and their variance. The role of bias is dominant – noise standard deviation is overestimated - and the main task is to decrease it. According to experiments carried out for ten variants (parameter sets) of estimation method, the best results are, on the average, obtained if block size is equal to 32 and local estimates are processed using sample median. Computational efficiency is analyzed and it is shown that processing can be done quite quickly. This allows expecting real-time implementation for such applications as electrocardiogram and speech processing

The subject of the study in the article is the mathematical model of the propulsion system. It is built on the basis of the formed transfer functions of the elements. The goal is to rationalize the process of heating the onboard propulsion system on the basis of mathematical model under given constraints. Tasks: formalization of processes in an electric heating engine with a working body ammonia; formalization of the model of the onboard propulsion system; formation of the structural scheme; consideration of physical processes occurring in the nodes of the propulsion system; description of gas and hydraulic processes; the description of thermodynamic and electrokinetic processes; The construction of a mathematical model based on transfer functions. The methods used are: models of transfer functions of a tank, a filter, a steam generator, a receiver and a jet, an engine with their ranges of work. The following results are obtained. A block diagram of the onboard propulsion system was added, supplemented with a control unit and a power supply system. A formalized mathematical model of an onboard propulsion system with working body ammonia is created. From it formed a model consisting of the key elements that make up the onboard propulsion system, which is used when rationalizing the heating of the working fluid. The scientific novelty of the results is as follows. The mathematical model of the electro-heating propulsion system onboard small space vehicles has been further developed through its application to calculate the traction characteristics of the dispenser, which makes it possible to use an ammonia electric heating rocket engine in the formation of a constellation of satellites. The limitations of the operating parameters of the model are introduced. It was proposed to conduct the further workability of the model in Matlab Simulink. Thus, a rational value of the current and voltage parameters will be obtained, at which the time of the system's output to the operating mode will be minimal, and the thrust is maximum for the given operating temperature and pressure ranges

Significant fluctuations of the current temperature and relative humidity of the ambient air lead to significant changes in the thermal load on the cooling system at the inlet of gas turbine units (GTU), which acutely raises the problem of choosing their installed (design) thermal load. Calculations of ambient air cooling processes were carried out for different climatic conditions, for example, southern Ukraine (Mykolaiv) and Central China (Beijing). It is  analyzed two methods of determination of the installed (design) cooling capacity of the ambient air cooling system at the GTU inlet according to the maximum current reduction of fuel consumption and according to the maximum rate (increase) of annual reduction of fuel consumption following to increasing of the installed cooling capacity, calculated by summarizing the current values of fuel consumption reduction. It is shown that the values of the installed cooling capacity of the air cooling system at the GTU inlet, determined by both methods, are close enough but differ significantly for different climatic conditions. The advantage of the method of calculating the installed cooling capacity of the air cooling system at the GTU inlet according to the maximum rate of annual reduction in fuel consumption is the possibility of a more precise definition of it due to the absence of significant fluctuations in the annual reduction in fuel consumption, calculated by summarizing the current values of fuel consumption reduction. Since the maximum reduction in fuel consumption per year is achieved with some decrease in the rate of its increment at high values of the design cooling capacity, required in the hottest hours in the summer and excessive in somewhat cool periods (at night and in the morning even in the summer), the installed cooling capacity, determined according to the maximum rate of the reduction of fuel consumption, will be insufficient in times of increased thermal loads above their design value. In such cases, the elimination of the deficit in cooling capacity is possible by using an excess of cold accumulated during reduced thermal loads

The article shows that the use of modern navigation systems and complexes for controlling the movement of water transport vehicles allows for safe navigation. It is substantiated that the proper work of navigation equipment – radio navigation complexes – depends on their technical condition. Thus, the presence in the radio navigation complexes of water transport facilities of a large number of electronic elements and radio channels and the aggressive environment of their operation increase the role of methods and instruments for monitoring and diagnosing the technical state of the radio navigation complexes during operation to ensure the trouble-free operation of water transport facilities. In determining the technical state of the radio navigation complexes of water transport vehicles there is a known contradiction in the control of complex systems of control: the provision of a given reliability of information about the technical state of the radio navigation complexes of the movement of water transport means requires an increase in the volume and accuracy of measurements in assessing their characteristics on one side, on the other - methods for automating the process of synthesizing the measurement signals and processing feedback on them for this. Within this contradiction, the actual scientific problem is the development of methods for synthesizing measurement signals and processing reviews on them to increase the reliability and efficiency of automated control of the technical state of the radio navigation systems for controlling the movement of water transport vehicles. The purpose of this work is to develop a method for calculating the function of distribution of parameters of control of radio navigation complexes of water transport vehicles. The conditional distribution function is proposed, which is the main quantitative characteristic of the control of the radio navigation complexes of water transport facilities. This feature contains all the information about the control parameters and allows you to determine the technical state of the radio navigation complexes. The method of calculating the function of distribution of parameters of control of radio navigation complexes of water transport means is developed. Such a method is proposed to be used in substantiating the characteristics of the measuring signals of the control of the radio navigation complexes of the means of water transport during operation
