The Digital Engagement of Older People: Systematic Scoping Review Protocol (Preprint)
Authors: Kebede Abraham Sahilemichael , Ozolins Lise-Lotte , Holst Hanna , Galvin Kathleen
Published: December 2020

BACKGROUND

There is an ongoing negative narrative about aging that portrays older people as a socioeconomic burden on society. However, increased longevity and good health will allow older adults to contribute meaningfully to society and maximize their well-being. As such, a paradigm shift toward healthy and successful aging can be potentially facilitated by the growing digital technology use for mainstream (day-to-day activities) and assisted living (health and social care). Despite the rising digital engagement trend, digital inequality between the age groups persists.

OBJECTIVE

The aims of this scoping review are to identify the extent and breadth of existing literature of older people’s perspectives on digital engagement and summarize the barriers and facilitators for technological nonuse, initial adoption, and sustained digital technology engagement.

METHODS

This review will be based on the Arksey and O’Malley framework for scoping reviews. The 6-stage framework includes: identifying research questions, identifying relevant studies, study selection, charting the data, summarizing and reporting the results, and a consultation exercise. Published literature will be searched on primary electronic databases such as the Association of Computing Machinery, Web of Science, MEDLINE, PsycINFO, CINAHL, and ScienceDirect. Common grey literature sources will complement the database search on the topic. A two-stage (title/abstract and full article) screening will be conducted to obtain eligible studies for final inclusion. A standardized data extraction tool will be used to extract variables such as the profile of the study population, technologies under investigation, stage of digital engagement, and the barriers and facilitators. Identified and eligible studies will be analyzed using a quantitative (ie, frequency analysis) and qualitative (ie, content analysis) approach suitable for comparing and evaluating literature to provide an evaluation of the current state of the older person’s digital engagement. Inclusion will be based on the Joanna Briggs Institute–recommended participant, concept, and context framework. Articles on older people (65 years and older), on digital technology engagement, and from a global context will be included in our review.

RESULTS

The results of this review are expected in July 2021.

CONCLUSIONS

The findings from this review will identify the extent and nature of empirical evidence on how older people digitally engage and the associated barriers and facilitators.

Authors: Ahmed Arfan , ALi Nashva , Aziz Sarah , Abd-Alrazaq Alaa A , Hassan Asmaa , Khalifa Mohamed , Elhusein Bushra , Ahmed Maram , Ahmed Mohamed Ali Siddig , Househ Mowafa
Published: December 2020

BACKGROUND

Anxiety and depression rates are at an all-time high along with other mental health disorders. Smartphone-based mental health chatbots or conversational agents can aid psychiatrists and replace some of the costly human based interaction and represent a unique opportunity to expand the availability and quality of mental health services and treatment. Regular up-to-date reviews will allow medics and individuals to recommend or use anxiety and depression related smartphone based chatbots with greater confidence.

OBJECTIVE

Assess the quality and characteristics of chatbots for anxiety and depression available on Android and iOS systems.

METHODS

A search was performed in the App Store and Google Play Store following the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) protocol to identify existing chatbots for anxiety and depression. Eligibility of the chatbots was assessed by two individuals based on predefined eligibility criteria. Meta-data of the included chatbots and their characteristics were extracted from their description and upon installation by 2 reviewers. Finally, chatbots quality information was assessed by following the mHONcode principles.

RESULTS

Although around 1000 anxiety and depression related chatbots exist, only a few (n=11) contained actual chatbots that could provide the user a real substitute for a human-human based interaction, even with today's Artificial Intelligence advancements, only one of these chatbots had voice as an input/output modality. Of the selected apps that contained chatbots all were clearly built with a therapeutic human substitute goal in mind. The majority had high user ratings and downloads highlighting the popularity of such chatbots and their promising future within the realm of anxiety and depression.

CONCLUSIONS

Anxiety and depression chatbot apps have the potential to increase the capacity of mental health self-care providing much needed assistance to professionals. In the current covid-19 pandemic, chatbots can also serve as a conversational companion with the potential of combating loneliness, especially in lockdowns where there is a lack of social interaction. Due to the ubiquitous nature of chatbots users can access them on-demand at the touch of a screen on ones’ smartphone. Self-care interventions are known to be effective and exist in various forms and some can be made available as chatbot features, such as assessment, mood tracking, medicine tracking, or simply providing conversation in times of loneliness.
Understanding Side Effects of Antidepressants: Large-scale Longitudinal Study on Social Media Data (Preprint)
Authors: Saha Koustuv , Torous John , Kiciman Emre , De Choudhury Munmun
Published: December 2020

BACKGROUND

Antidepressants are known to show heterogeneous effects across individuals and conditions, posing challenges to understanding their efficacy in mental health treatment. Social media platforms enable individuals to share their day-to-day concerns with others and thereby can function as unobtrusive, large-scale, and naturalistic data sources to study the longitudinal behavior of individuals taking antidepressants.

OBJECTIVE

We aim to understand the side effects of antidepressants from naturalistic expressions of individuals on social media.

METHODS

On a large-scale Twitter data set of individuals who self-reported using antidepressants, a quasi-experimental study using unsupervised language analysis was conducted to extract keywords that distinguish individuals who improved and who did not improve following the use of antidepressants. The net data set consists of over 8 million Twitter posts made by over 300,000 users in a 4-year period between January 1, 2014, and February 15, 2018.

RESULTS

Five major side effects of antidepressants were studied: sleep, weight, eating, pain, and sexual issues. Social media language revealed keywords related to these side effects. In particular, antidepressants were found to show a spectrum of effects from decrease to increase in each of these side effects.

CONCLUSIONS

This work enhances the understanding of the side effects of antidepressants by identifying distinct linguistic markers in the longitudinal social media data of individuals showing the most and least improvement following the self-reported intake of antidepressants. One implication of this work concerns the potential of social media data as an effective means to support digital pharmacovigilance and digital therapeutics. These results can inform clinicians in tailoring their discussion and assessment of side effects and inform patients about what to potentially expect and what may or may not be within the realm of normal aftereffects of antidepressants.
Covid-19 and Mental Health: The Growing Need of Telecounseling in Indonesia
Authors: Saptandari Edilburga Wulan
Published: December 2020

Covid-19 pandemic has not only threatened public physical health but also mental health. The mental health effects of this pandemic can include anxiety of contamination and death as well as feelings of isolation. Counseling has been proved as an effective method of supporting the physical and psychosocial needs of the individual affected. Technological advancement makes it possible for psychologists and clients to carry out counseling sessions without the needs of physical presence in one place by utilizing various modes of telecommunication. This form of counseling is known as telecounseling. As a relatively new form of counseling in Indonesia, numerous aspects need to be considered in implementing telecounseling. This article aims to explore the considerations taken in conducting telecounseling sessions in Indonesia. Their opportunities and challenges which might not be present in an offline face-to face counseling will also be discussed. Psychologists need to develop both practical and technical competencies to be able to provide adequate telecounseling services. Suggestions for development are also given to other relevant parties such as psychological service institutions, professional associations, and education providers.

Complicated analytic and synthetic mechanisms of speech signal processing underlie the basis for listening comprehension skills, therefore, while teaching listening skills, the mechanisms of oral foreign speech perception remain crucial and properly addressed. The article looks into the formation of the perceptual language base while perceiving German as L2 speech. In this paper, we discuss a number of issues including the priority role of listening comprehension, mechanisms of perception and the interaction of the articulatory and perceptual language bases. The word is viewed as the basic unit of perception. The listening mechanisms of the German word are described in terms of significant linguistic features. The necessity of purposeful formation of basic oral speech perception skills is shown. The operating units of such formation are sets of keywords in the unity of their sound patterns and meanings, the latter characterized by the perception relevant features. The techniques of operating these features in the designed coursebooks are also observed.

Authors:   TATIANA V. BURDAEVA Samara State Transport University, BURDAEVA TATIANA V.
Published: December 2020

This article aims to study the syntactic concept of causality reflected in the model of a complex sentence with causal clauses. The syntactic concept of causality is viewed as a presentation of coherent-cohesive connections in the railway-related texts taken from the German research articles published in specialized journals in the period of 2000-2017. During the study, the following methods were applied: continuous sampling, linguistic description and observation, syntactic modeling, the statistical method, cognitive modeling and prototype analysis techniques. The research enabled to demonstrate the connection of a formal-grammatical and a content-thematic sides in the railway-related texts revealed within the four aspects such as syntactic, semantic, pragmatic and hermeneutic (conceptual) ones. A detailed analysis of the syntactic means such as conjunctions, word order, theme-rhematic component, tense forms of the verb, modality in causal clauses, made it possible to identify the patterns of the expression of coherent-cohesive relations in the railway-related texts...

In feed production, scientists suggest using high-quality plant culture, soy, to replace animal protein. Soy cannot be fed without pre-heat treatment due to the presence of anti-nutritional substances in it. Analysis of existing technology has shown that micronization, roasting, ultra-high-frequency processing, extrusion, autoclaving, and others are used to remove anti-nutritional substances. These methods are energy-intensive and have a complex design. (Research purpose) The research purpose is in developing a scheme and a working sample of a plant for cooling soybeans using a non-water vibrating conveyor and conduct research on its operation. (Materials and methods) Authors applied methods of system analysis and synthesis of existing knowledge in the field of ongoing research on the development of energy-saving soybean cooler, based on the provisions of the theory of heat and mass transfer. The article presents flow diagram of the cooling of soy. The vibrations of the chute of a non-drive conveyor in the cooling chamber are carried out from the vibration drive of the main conveyor due to the use of the reactive energy of its spring. (Results and discussion) It was revealed experimentally that in regions with a moderate climate and an outdoor temperature of 8-10 degrees Celsius, tempered soy can be cooled to the normalized values when it moves in the cooling chamber for 105-140 seconds. In regions of the country with a long period of high temperatures (20-25 degrees Celsius) of outdoor air, the cooling efficiency of tempered soybeans decreases. (Conclusions) The article presents the design parameters of the soybean cooling chamber for warm climate conditions. Authors developed and tested a working sample of the installation. The proposed technical solution provides a reduction in energy consumption compared to traditionally used equipment by up to 30 percent.

Water supply for agricultural enterprises differs from water supply for industrial enterprises. Depending on the technological process, it is necessary to provide water of the appropriate quality with the required temperature. Because agricultural production consumes a large amount of heated water and it has a periodic nature, the use of classical water heating devices is impractical due to low efficiency. (Research purpose) The research purpose is in studying the energy efficiency of a flow-through water heaters of various designs. (Materials and methods) Authors reviewed the heating elements that are used in water heating devices. An eight-channel ARIES UKT38 temperature meter with a set of thermocouples was used to study the temperature parameters, and an Energomer device of the MT4014 brand and a V7-35 multimeter were used to control the electrophysical parameters. (Results and discussion) Semiconductor heating elements manufactured using the technology presented in patent No. 172386 are superior to tubular heating elements in such parameters as reliability and efficiency. During long-term operation, the temperature on the heating element at the tubular heating element is in the limit value. Flow-through water heaters with these heating elements can only be used in repeated-short-term operation mode. During long-term operation, the temperature on the heating element of the semiconductor heating element does not change and does not exceed the limit values, and the operating mode of flow water heaters with semiconductor heating elements is repeatedly-continuous. (Conclusions) The use of new technical solutions and new technologies for providing hot water supply at agricultural enterprises will help to increase the reliability and efficiency of the equipment used.

Authors:   Kuban State Agrarian University named after I.T. Trubilin, LEBEDEV DMITRIY , ROZHKOV EVGENIY
Published: December 2020

Sable is considered a symbol of Russia. Animal furs were obtained by hunting. This was the main reason for the decrease in the number of the animals, which was almost exterminated. This situation was changed by hunting scientists who started breeding it in nurseries and releasing it. Russia is a leading country that supplies furs to the world market. It is important to design a sable farm correctly, taking into account scientific developments in achieving economic profit without disturbing the animal population. The most widespread technology is the breeding of ground-type cellular. However, this technology has a number of disadvantages. Therefore, the development of optimal technology for breeding with maximum economic effect and low costs of human labor is an urgent problem in the fur industry. (Research purpose) The research purpose is in conducting an analytical review of existing technologies for breeding sables and develop a multi-level optical-electronic system for monitoring the vital activity of sables in underground cell content. (Materials and methods) The article considers the main advantages and disadvantages of existing technologies for keeping and breeding sables. (Results and discussion) Authors propose a technology for underground cell keeping of sables with automatic control of microclimate and animal life in order to improve the quality of furs and reduce labor costs. The article determines the possibility of implementing optimal conditions for the normal life of sables not only in the North, but also in regions with high temperatures. (Conclusions) The article presents a scheme for a multi-level underground sable farm of a cellular type with optoelectronic control of the microclimate and vital activity of animals. The article presents an analytical description of the main parameters and the algorithm of operation of a multi-level optical-electronic system for monitoring the vital activity of sables.

Disease-drug and drug-drug interaction in COVID-19: risk and assessment
Authors: Kumar Devendra , Trivedi Neerja
Published: December 2020

COVID-19 is announced as a global pandemic in 2020. The emergent
outbreak of COVID-19 prompted by severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2) keeps spreading globally. Its mortality and
morbidity rate are rapidly increasing, and medication options are still
limited. A patient’s immune response plays a pivotal role in the
pathogenesis of COVID-19. Hyperinflammatory state may sparks significant
imbalances in transporters and drug metabolizing enzymes, and subsequent
alteration of drug pharmacokinetics that may result in unexpected
therapeutic response. The present scenario has accounted the requirement
for therapeutic opportunities to relive and overcome this pandemic.
Despite the fact, the diminishing developments of COVID-19, there is no
drug still approved to have significant effects with no side effect.
Based on the evidence, many antiviral and anti-inflammatory drugs have
been authorized by the Food and Drug Administration (FDA) to treat the
COVID-19 patients even though not knowing the possible drug-drug
interactions. Hydroxychloroquine is the first medicine chosen for the
treatment of disease. Remdesivir, favipiravir, and molnupiravir are
deemed the most hopeful antiviral agent; by improving health of infected
patients. The dexamethasone saved the lives of seriously ill patients.
Many randomized and controlled clinical trials are taking place to
further corroborate these agent’s safety and efficacy in handling
COVID-19. The current review summarizes the involvement of drug
transporters and drug metabolizing enzymes for the existing drugs and
gives the opinion on the potential drug-drug interactions in an
inflammatory state. This may permit the individualization of these drugs
thereby enhancing the safety and efficacy.
Relevance of topographic control on hydrogeological properties of the weathered granite gneiss aquifer in watershed perspective -- Usri sub-basin, Giridih, India
Authors: Kumar Ashok
Published: December 2020

Usri, a southward sloping fourth order drainage sub-basin of Barakar
river, is located in the northern margin of Chhotanagpur plateau,
Giridih, India. Gently sloping undulating landforms devoid of hills and
outcrops is main characteristics of this sub-basin. Topographic
elevation varies between 310 to 390 m MSL. Geographically it is located
between lat 24.38° N to 24.54° N long and 86.07° E and 86.28° E
longitudes. Thick weathered horizon developed over homogenous Archean
granite-gneiss is the principal unconfined aquifer system. Basement
topographic (weathering depth) and water table have been correlated with
the surface topographic features (landforms). Presence of considerably
thick weathered horizons, devoid of rock exposures, regional uniformity
in geomorphic characters and its location at fringe of plateau provides
favorable condition for correlation of surface topography with basement
topography and water table. It has been observed that basement surface
is replica of ground surface only in regional or watershed perspective
with reference to common datum. The basement surface is not always exact
replica of ground surface at micro watershed scale. In many cases,
basement surface is reverse of ground surface. The depth basement has
remained constant along the basin water-divide situated near the margin
of the plateau. The depth of basement (weathered horizon) is higher in
upper reaches than lower reaches on the micro water-divides (upland) as
well as in the drainage depressions (channels) within the sub-basin. The
upper reaches of the sub-basin mainly along the basin water-divide has
better groundwater prospects than lower reaches. There is no definite
trend of water table with respect to ground and basement topography.
Many places water table is shallow on the micro water-divides (upland)
and deep in drainage depressions (channels). The established
correlations are likely to be applicable in the other geographical area
where similar watershed and geological characteristics exits.

Authors: Kapetula José Gueleka
Published: December 2020

O objetivo deste artigo é o de apresentar os resultados do estudo realizado sobre a interpretação de sujeitos pronominais de 3ª pessoa por falantes nativos do português de Angola (doravante, PA), tendo em conta antecedentes com características diferentes. Pretendeu-se comparar estes resultados com o dos falantes do português europeu (doravante, PE) e com os resultados obtidos em estudos semelhantes para o português brasileiro (doravante, PB). Os resultados obtidos mostraram-nos que: i) no PA os sujeitos nulos são preferencialmente interpretados como correferentes com antecedentes quantificados, os sujeitos pronominais também aceitam a interpretação de variável ligada, o que é improvável numa língua de sujeito nulo; ii) em contexto de orações completivas, os pronomes nulos estabelecem preferencialmente correferência com sujeito matriz; em contexto de adverbial a preferência do pronome nulo por retomar o sujeito matriz não é clara; nestes dois contextos, os sujeitos pronominais tanto podem retomar um antecedente sujeito como um antecedente objeto; iii) no PA aceita-se preferencialmente um tipo de leitura que recupera parcialmente o sujeito na posição mais alta da frase, ainda que esta tendência não seja tão marcada como a que se verifica para o PE; iv) nos contextos em que as leituras são forçadas, o sujeito nulo no PA aceita uma leitura correferente com antecedente sujeito, tal como no PE, assim como aceita também uma leitura correferente com um antecedente objeto, ao contrário do PB.

Authors: Rabeinia Maryam , Saemi Esmaeel , Abedanzadeh Rasool
Published: December 2020

The purpose of the present study was to investigate the effect of overweight stereotype threat on children?s motor learning. Twenty-four children (Mage = 9.25 ? 0.53 years) were conveniently selected and randomly assigned into two groups of stereotype threat (with emphasis on individual characteristics, namely, overweight) and control group. The task consisted of maintaining the balance on the stabilometer during 30-second trials. One trial in the pre-test, 10 trials in the acquisition phase and 5 trials in the retention test were run. The findings revealed lower motor learning among the overweight stereotype group compared to the control group. Therefore, it is suggested that in similar situations, coaches can reduce stereotype threat emphasizing on the ineffectiveness of individual characteristics, i.e., overweight on motor performance of children thereby prevent performance and learning disruptions.
“A África está aqui!”: Desconstrução de concepções etnocêntricas na História afrobrasileira
Authors: Martins de Paiva Kênya Jessyca , Da Silva Mariana Soares
Published: December 2020

O trabalho parte das atividades realizadas na disciplina de Estágio III, do curso de História, da Universidade Federal do Pampa (UNIPAMPA). O estágio ocorreu no Clube Social 24 de Agosto, localizado em Jaguarão, em 2013, e teve como objetivo construir instrumentos metodológicos para o desempenho de uma ação docente que percebesse o ensino de História presente em diferentes espaços. A proposta prática foi surgindo a partir da pesquisa do acervo da instituição, em que foram analisadas fontes escritas, bibliográficas e atas, bem como por meio do diálogo com os membros do clube. Visando demonstrar e mediar o conhecimento sobre a cultura afrodescendente, confeccionamos uma exposição na Escola Estadual de Ensino Fundamental Pio XII, intitulada “A África está aqui! Um pouco das histórias do Clube 24”. Posteriormente, realizamos uma oficina de máscaras africanas, com o intuito de aproximarmos os alunos de uma prática usual dessa cultura. A intenção das ações foi fazer com todos tivessem maior contato com a cultura afro, desenvolvendo uma percepção crítica para desconstruir concepções etnocêntricas legitimadas por um ensino de História tradicional. Conseguimos alcançar alguns dos objetivos, como a problematização das crianças em relação ao tema, visto que a todo o momento surgiram várias perguntas, por exemplo, sobre o que era um quilombo e o que era um continente, além delas relacionarem a capoeira com as suas vidas. Nesse sentido, verificamos a relevância desse trabalho para auxiliar na construção de cidadãos pensantes e preocupados com questões sociais e étnico-raciais.

Published: December 2020

Based on the agency theory, this paper analyzes whether family firms pay more dividends compared to no-family firms and identifies whether the board composition affects the dividend policy. Brazil and Chile have established mandatory dividends, retain lower cash holdings, pay higher dividends compared with other markets in the region. The sample of study is composed by 853 observations from 49 Brazilian and 32 Chilean top publicly listed firms in terms of market capitalization over the 11-year period from 2004 to 2014. Using an unbalanced panel data, results indicate that family controlled firms distribute more dividends and board composition namely; board size and the proportion of women on the board have a significant and positive impact on the dividend policy of the firm. By contrast, COB-CEO duality has a negative effect. Thus, dividend policy constitutes an effective corporate governance mechanism in mitigating the family’ expropriation of minority shareholders’ wealth.

This paper mainly proposed and researched based on wavelet transform, and then used the X-map denoising technique of value filter. In other words, the value image was filtered in the spatial domain, and the value filtering was used as the standard pulse (salt) noise, also used as in the wavelet domain. After the filtered image was decomposed by biorthogonal double wavelet transform, a wavelet coefficient matrix was generated, and a soft threshold quantisation process was performed on the wavelet coefficients to produce a new wavelet coefficient matrix. In the end, they used a new wavelet coefficient matrix for image reconstruction. The processing resulted that the denoising method proposed in this paper showed that the X image can be denoised, which not only reduced the X-picture-like noise but also preserved the X-picture-like details as much as possible. It also helped to enhance diagnostic accuracy and reduced the difference in reading.

The present study aimed to assess the season and pregnancy influence on minerals serum of local rabbits raised in semi-arid climate type. Fifty-nine multiparous does was used in this study during 2019. The semi-intensive rhythm of reproduction was used. All pregnant does were at the late stage of pregnancy at the sampling date. Serum samples were collected in two seasons: winter and summer. In this study, biochemical parameters concentrations of pregnant rabbits were significantly higher (p<0,05) compared with non-pregnant rabbit. The value of biochemical parameters total protein, albumin, triglyceride, cholesterol, calcium, and phosphorusus changed significantly. In this study, most parameters were influenced by pregnancy.

Authors: Vasilev Dimitar , Kaschieva Maria
Published: December 2020

The study was performed at the Experimental Station of Agriculture - Khan Krum in the period 2018-2019. The experimental plantation was established in 2001, the early Bigareau Burlat, middle early Bing and the late Germersdorfer and Van were tested. The planting material was produced on a mahaleb rootstock. The distance of planting was 6 meters interrow spacing and 5 meters intrarow spacing. The experiment was based on three replications each of them reported on a separate tree. When analyzing the frost percentage of flowers, 400 blossoms were taken from three levels of the crown of each tree, the same number of fruits were taken to determine the cracking percentage. Percentage of damaged blossoms, yield kg/ha and percentage of fruit cracking as a result of fallen rains during harvest were established. The purpose of the study is to investigate the influence of abiotic factors on the yield and quality of four sweet cherry cultivars. In this regard, the frost percentage in the range of values was 67,3 - 100%. Bigareau Burlat yield was not obtained, and it was relatively low from Germersdorf and Bing (20,1 - 24,6 kg/ha) at Van 84,6 kg/ha. The number of cracked fruits due to fallen rains during harvest was relatively high in Van and Bing (39,8 - 47,4%), while in the Germersdorf cultivar it was lower - 21,2%.

Study Regarding Changes in Decision-Making Process During the Crisis Period
Authors: Ranf Diana , Gorski Hortensia
Published: December 2020

Why the decision? Because we have to make decisions every day, more important or less important decisions that lead our lives in a certain direction, in both cases being necessary to choose between several courses of action. The decision is part of our lives and making the optimal decision is important, whether it comes from managers or from regular individuals. An organizational environment characterized by insecurity, frequent and sudden changes has a negative impact on the management of an organization. Under these circumstances, the reaction to these changes, instabilities materialize in quick, correct decisions that induce organizational stability. The main objective of the article is to analyze the decision-making process within the organizations that constitute the private environment in Sibiu. The question that the article wants to answer is: the expertise (knowledge, theories, methods) of managers in decision making sufficient or does this new context require an adaptation, reorganization of the decision-making process? The article contains a qualitative interview-based investigation, which is the premise of a comprehensive research based on a questionnaire to provide solutions to the problems identified.
Localization in Wireless Sensor Networks: A Review
Authors: Sneha V. , Nagarajan M.
Published: December 2020

Wireless Sensor Network (WSN) has been a source of attraction for many researchers as well as common people for the past few years. The use of WSN in various environmental applications like monitoring of weather, temperature, humidity, military surveillance etc. is not limited. WSN is built on hundreds to thousands of nodes where each node is a sensor whose main role is to sense data. These nodes are restricted to various constraints like power, energy, efficiency and deployment. The location of deployment influences the efficiency of data transmission. In this paper we briefly discuss on localization process in WSN and the classification of localization methodologies, namely centralized localization and distributed localization. The various techniques like ToA, TDoA, AoA and RSSI that are used to estimate the distance among the nodes are studied in detail. The localization issues categorized under proximity-based, range-based and range-free localization are discussed in detail. This paper also focuses on how the nodes with GPS can contribute to the localization process. The merits and demerits of using GPS have also been looked into. The various approaches of range-based techniques like Bounding box, SumDistMinMax, geometric methods, general techniques have been discussed briefly. We will also discuss on how the factors like path loss, noise, propagation, device measurements, connectivity, power control and tracking can influence the measurements in localization. In the tracking process we have briefly discussed about the variants of Kalman filter that can be used in detecting the direct path, strongest path and undirected path. This paper as a whole is just a brush up of the localization methodologies used in wireless sensor networks. This paper may give idea to the researchers to develop efficient algorithms to localize nodes with accuracy adapting to different techniques with respect to the environment and applications to be designed.
A Novel Alternative Algorithm for Solving Integer Linear Programming Problems Having Three Variables
Authors: Alan Kadriye Simsek
Published: December 2020

In this study, a novel alternative method based on parameterization for solving Integer Linear Programming (ILP) problems having three variables is developed. This method, which is better than the cutting plane and branch boundary method, can be applied to pure integer linear programming problems with m linear inequality constraints, a linear objective function with three variables. Both easy to understand and to apply, the method provides an effective tool for solving three variable integer linear programming problems. The method proposed here is not only easy to understand and apply, it is also highly reliable, and there are no computational difficulties faced by other methods used to solve the three-variable pure integer linear programming problem. Numerical examples are provided to demonstrate the ease, effectiveness and reliability of the proposed algorithm.
