Optimal Querying for Communication-efficient ADMM using Gaussian Process Regression
Authors: Duarte Vera Tudela Aldo , Nghiem Truong , Wei Shuangqing
Published: October 2022

In distributed optimization schemes consisting of a group of agents connected to a central coordinator, the optimization algorithm often involves the agents solving private local proximal minimization sub-problems and exchanging data frequently with the coordinator to solve the global distributed problem. Such schemes usually cause excessive communication costs to the system, leading to the need for communication reduction for scenarios where communication is costly. The integration of Gaussian Processes (GPs) as a learning component to the Alternating Direction Method of Multipliers (ADMM hase been proven successful in learning each agent’s local proximal operators. Consequently, such a learning technique is effective to reduce the communication between the agents and the coordinator. A key element for the integration of GP in the ADMM algorithm is the mechanism upon which the coordinator decides when communication with an agent is required. The decision strategy used in this setting strongly affects the overall communication expenditure reduction and the ADMM’s algorithm performance. For that reason, we construct a general framework presenting a systematic querying mechanism as an optimization problem that balances the ideas ofmaximizinge the communication cost reduction while minimizing the prediction error. Motivated by such a framework, we propose different query strategies using the uncertainty measurement given by GP, to determine if the prediction is reliable enough to skip a communication round. We propose a joint query strategy following a simplification of the general framework that minimizesana L1 norm communication cost constraint by the trace of the joint uncertainty of the ADMM variables which is calculated using all agents’ prediction uncertainty. Additionally, we derive three different decision mechanisms (motivated by a confidence interval analysis) that make their decision by analyzing an uncertainty measurement for each agent individually. We integrate multiple measures to quantify the trade-off between the communication cost reduction and the optimization solution’s accuracy/optimality. The proposed methods can achieve significant communication reduction and good optimization solution accuracy for distributed optimization, as demonstrated by extensive simulations of a distributed sharing problem with quadratic cost functions for the agents.

Published: October 2022

Asymmetric transmission plays an important role in many electromagnetic systems. Different to the asymmetric transmissions in full space, angular-asymmetric transmissions support different characteristics for symmetrical oblique incidences in half space, which has great potentials for antenna designs and wireless systems. This communication designs and demonstrates a dual-band multi-functional metasurface with angular-asymmetric transmission and frequency selection under oblique incidences. At 8.7 GHz, the 30° incident TM wave is bounded in the metasurface, and the −30° incident TM wave transmits, which presents an angular-asymmetric transmission. At 10.4 GHz, both ±30° TM oblique incident waves can be transmitted, which presents a frequency selection function. The metasurface sample with optimized geometry parameters has been fabricated and measured, and the measurement results agree well with the simulation results.

Authors: MENEZES Daniel Francisco Nagao , VILLARREAL Roberto Cañedo
Published: October 2022

O contexto sul-americano da primeira década do século XXI possibilitou o surgimento de diversas iniciativas relacionadas à Economia Social e Solidária (ESS) na agenda de integração da região. Em geral, tais iniciativas foram apresentadas como respostas às crises provocadas pelo modelo neoliberal imposto às populações desses países no final do século anterior. A perspectiva da ESS foi incorporada na busca de soluções e, juntamente com o estabelecimento de estratégias e instituições regionais com foco na dimensão social do desenvolvimento, representou um importante avanço no sentido de oferecer contribuições aos esforços de promoção de alternativas das sociedades desses países. Ao mesmo tempo, as agendas de desenvolvimento propostas por organismos internacionais reforçaram as iniciativas estabelecidas na região e forneceram metas e indicadores para as políticas públicas implementadas. A estratégia multilateral proposta pela ONU estabelece a Agenda 2030, onde as iniciativas de ESS podem servir como ferramentas relevantes para alcançar o cumprimento de tais objetivos; além disso, a integração regional surge como uma estratégia importante nesta situação. Com base no exposto, esta proposta de trabalho tem como objetivo analisar os processos contemporâneos de integração latino-americana a partir da ESS, evidenciando as possibilidades e os desafios dessa perspectiva para o alcance do desenvolvimento sustentável

Published: October 2022

Una de las restricciones más significativas para el desarrollo y crecimiento de los pequeños productores es el acceso a los recursos financieros provistos por el sistema bancario. Particularmente por lo restrictivos de los requisitos que se exigen, los que se constituyen en una barrera de acceso para la mayoría de este tipo de productores. A esto se le suma lo oneroso de otras alternativas de financiamiento. La economía solidaria llama la atención sobre la exclusión o a la inclusión subordinada de sujetos de crédito considerados como de mayor riesgo a las organizaciones económicas capitalistas y plantea formatos organizativos alternativos para su inclusión financiera. Este trabajo busca identificar los aprendizajes y limitaciones que se plantean a la hora de implementar y autogestionar alternativas financieras como los Fondos Rotatorios para cubrir las necesidades de pequeños productores. El trabajo analiza la ejecución de Fondos Rotatorios por parte de la Cámara de Apicultores Pampero (CAP), la que articula con Cooperativa de Trabajo Apícola Pampero Limitada (CTAPL).

Introduction: The sanitation requirement for the sustainable development goals (SDGs) is to certify household better sanitation, and it is the target of SDGs. Developed sanitation is that which ensures the hygienic separation of human excreta from human contact. The Government of Bangladesh has a strategy to safeguard sanitation at an agreeable level for all by 2030. Aim of the study: The study aims to investigate the relationship between sanitation microfinance and sanitation condition in Bangladesh. Methods: A cross-sectional study was carried out in each district of Dhaka, Chittagong, Rajshahi, and Khulna from August 2019 to September 2019 for five weeks Semi-structured questionnaires and face did data collection face interview techniques from the head of households. Verbal consent was taken before recruiting the study population. Completed data forms were reviewed, edited, and processed for computer data entry. The data analysis was performed using Statistical Package for the Social Sciences (SPSS) Version 25.0, two-sample ttest, binary probit model. Result: Among 120 participant households and 120 non-participant households in this microfinance program, household satisfaction in sanitation conditions among microfinance households is good. Microfinance is applicable for low economic households, where the annual income was 1501 to 3000 USD (I USD=84 local currency). Both sanitation outcomes and nutrition outcomes had a strong association with sanitation microfinance(p<.05). With sanitation microfinance improved sanitation outcome (76.67%) is more than that without microfinance (47.50%). On the other hand, the nutrition condition of under-five children at the household level with sanitation microfinance was more (90%) than that of without microfinance (48.47%). Conclusion: Earning the Millennium Development Goal (MDG) to split the number of people without access to enhanced sanitation presents a substantial challenge for evolving and least developed countries. The 1st known search into the potential of microfinance to unleash latent claims for sanitation improvements among low-income households in a developing country.

Objective.
Development of local clinical protocols for antibacterial therapy of COVID-19-associated bacterial pneumonia in the therapeutic department of the city clinical hospital based on an analysis of the treatment process in patients with COVID-19-associated pneumonia.

Materials and Methods.
A retrospective analysis of 1382 cases of hospitalization in the therapeutic department of patients with COVID-19-associated pneumonia for the period from 2020 to 2021 was carried out. The structure of etiotropic therapy, the frequency and timing of microbiological studies of the biomaterial, the manifestations of the main markers of bacterial infection during dynamic monitoring of clinical and laboratory parameters in patients prescribed antibiotic therapy, as well as statistics of the stay of patients in the therapeutic department of the hospital were assessed. Based on the results obtained in the course of microbiological studies, an assessment was made of the microbial landscape of the lower respiratory tract of patients with an analysis of the sensitivity of strains of the leading microflora to a wide range of antibiotics.

Results.
The study found that the dominant flora in COVID-19-associated pneumonia in hospitalized patients was gram-negative bacteria – K. pneumoniae, P. aeruginosa and A. baumannii – their proportion was more than 50%. Among K. pneumoniae strains, 89.4% were ESBL producers, 63.5% of the strains were resistant to carbapenems, which with a high probability allows them to be considered carbapenemaseproducing strains. Among the strains of P. aeruginosa, the proportion of strains resistant to carbapenems and with a high degree of probability being strains – producers of carbapenemase was 41.1%. Among strains of Acinetobacter spp. these were 76.4%, and associated resistance to fluoroquinolones and aminoglycosides was also demonstrated. Gram-positive microorganisms were found in 34.3% of cases and were mainly represented by strains of S. aureus (74.9%), only 26.4% of strains of this pathogen were methicillin-resistant.

Conclusions.
Microbiological monitoring conducted in 2020–2021 revealed the presence, among the pathogens of viral-bacterial pneumonia, at an early stage of hospitalization, a significant proportion of gram-negative bacteria with resistance of the MDR and XDR types. Based on the obtained microbiological data, starting empirical schemes for antibacterial therapy of secondary viral and bacterial pneumonia, which complicated the course of a new coronavirus infection COVID-19 caused by the SARS-CoV-2 virus, were developed and proposed.

Published: October 2022

The influence of the main parameters of rotary cutting on the surface roughness, residual stresses and microhardness of the surface layer of the machined part is investigated. It is established that increasing the depth of cutting and feed increase the roughness, residual stresses and hardness of the surface layer. The influence of other cutting parameters on the quality of the surface layer is mainly related to the kinematic and dynamic features of processing. The possibilities of regulating the quality of processing by changing the cutting parameters are revealed.

Published: October 2022

Autism is one of those very complex prevailing neurodevelopmental disorders which are very difficult to diagnose. Since the discovery of this disorder, researchers, working in the field of Autism, have been proposing different methodologies to diagnose Autism. These proposals have been coming from the multiple fields. The present study is an attempt to see how insights from the field of conversation analysis can help find a simpler and better method of diagnosing autism. The study contends that Autists’’ ability to construct conversational loops reciprocates to their ratings on the GARS-3 Scale. Firstly, Conversations between eight autistic children and their speech therapists are recorded, transcribed and analyzed by following norms of conversation analysis. Then these results are compared with participants’ ratings on GARS-3 scale. Findings of the study validate researcher’s claim that there do exist a lucid link between conversational abilities of the autists and their scores on the GARS-3 Scale. Through these findings the researcher proposes conversation analysis as a methodology for diagnosing autism.

Computer-aided instructions have significant potential in increasing the educational experiences and facilitating the development of children with special needs (autistic children). Early intervention for autistic children helps their learning, language, and communication skills.  This study aimed to explore the perceptions of parents of autists and speech therapists regarding the use of computer-aided educational applications to improve the communication and learning of Autistic Students. A critical paradigm was used for this study, under this paradigm, mixed methods research was used. Under mixed methods research, an explanatory sequential design was used. All the parents of autists and speech therapists of Lahore were considered the population for this study. A purposive sampling technique was used to determine the desired sample size from the population. Seventy-three parents of autists and twenty-eight speech therapists participated in the study. For the quantitative phase, the purposive sampling technique was used. For the qualitative phase, only those parents of autists using mobile/computer applications for student communication and language development were selected. Four instruments were used in this study. The reliability for the parents of autists’ questionnaire was α=.77 and for the speech therapists' questionnaire was α=.96. Data was analyzed using SPSS. It is concluded that parents of autists and speech therapists have average to high perceptions (based on their means) regarding the usage of educational applications.  However, positive perceptions were shared by the speech therapists and parents of autists about the educational applications using these applications for specific purposes. It is also noted that an individualized set of activities are essential for autistic children.

Published: October 2022

Morcegos da espécie Anoura geoffroyi possuem ampla distribuição na região neotropical, ocorrendo nas Américas do Norte, Central e do Sul. A formação de grandes colônias potencializa o importante papel ecológico desenvolvido pela espécie na polinização de grande variedade vegetal. Neste trabalho, foi realizado o estudo concomitante em duas colônias de Anoura geoffroyi, dando ênfase à estrutura e dinâmica populacional da espécie. Essas colônias se encontram localizadas em uma das principais regiões de interesse mineral do Brasil, o Quadrilátero Ferrífero, estado de Minas Gerais. Como resultados, observamos que as colônias representam populações numerosas com uma variação na densidade populacional acentuada ao longo do ano podendo agregar milhares de indivíduos durante o início do período reprodutivo. Ambas as colônias apresentaram comportamento de segregação sexual com os abrigos ocupados majoritariamente por machos nos primeiros meses do ano. As fêmeas chegam nas cavernas para acasalamento no pico da estação seca. Estas permanecem no abrigo até próximo do fim da gestação, abandonando as cavernas estudadas no início do verão onde procuram outro abrigo (colônia maternidade) para a conclusão da gestação (nascimento) e posterior cuidado dos filhotes. Desta forma, concluímos que as características intrínsecas da história natural da espécie têm implicações importantes para a sua conservação já que a preservação dos abrigos diurnos está intimamente relacionada com o ciclo reprodutivo da espécie. Por sua vez, a legislação brasileira vigente permite a supressão de cavidades naturais subterrâneas tendo como base estudos que, a depender do período de amostragem, podem ser insuficientes para detectar o uso destes abrigos essenciais para a conclusão do ciclo reprodutivo de espécies consideradas relativamente comuns, com um papel ecossistêmico fundamental para ambientes epígeos e subterrâneos, e que não constam nas listas oficiais de espécies ameaçadas de extinção.

Mapas espeleológicos vêm sendo produzidos por processos manuais desde meados do século XIX, no Brasil, a partir de levantamentos topográficos e croquis. Nas últimas décadas, inovações tecnológicas como os medidores eletrônicos de distância e a comunicação com aplicativos de topografia de cavernas têm permitido a elaboração de mapas totalmente em meio digital, ainda com o emprego de procedimentos manuais. Atualmente, além dos escaneamentos a laser, levantamentos fotogramétricos de curta distância vêm sendo empregados para a geração de modelos 3D de cavidades e têm auxiliado na construção de mapas espeleológicos a partir de procedimentos automatizados que permitem a extração de informação métrica com precisão, contribuindo na redução de erros e tempo. Este processo permite a obtenção dos limites de uma cavidade em vistas clássicas como planta baixa, perfis longitudinais e cortes transversais e outros menos usuais, como os contornos verticais longitudinal e transversal, além da extração das curvas de nível e outras feições de interesse a serem vetorizadas a partir de mosaicos de ortofotos do piso, paredes e do teto da cavidade. Modelos fotogramétricos 3D de cavidades subterrâneas permitem o cálculo de variáveis espeleométricas, incluindo o volume, de difícil obtenção pelo método topográfico convencional e podem ser integrados a modelos de superfície topográfica com imagens de alta resolução, contribuindo na visualização e análise da paisagem e das características do seu local de inserção. Os levantamentos realizados na Gruta dos Sete Salões e na Mina do Veloso demonstraram que os modelos gerados apresentam uma geometria muito próxima do real, podendo ser realizados em cavidades naturais ou mesmo artificiais, como minas de ouro históricas. Seguindo-se o fluxo de trabalho proposto, visando a geração de mapas espeleológicos 3D, colocam-se como alternativa aos levantamentos topográficos tradicionais, sendo passível de aplicação, inclusive, em modelagens tridimensionais geradas a partir de nuvens de pontos por escaneamentos a laser.

Performance of Roads Implemented under the Roads 2000 Strategy in Central Kenya

Published: October 2022

The road sector in Kenya is an integral part of its economy. The country has approximately 170,000 kilometres of road network, managed by the line ministry through the Kenya Roads Board (KRB), Road Authorities, and other Agencies. Insufficient financial resources and organisational and operational systems with inadequate investment in maintenance have led to the devaluation of the road network as an asset, as well as the aftermath effects of high vehicle operating costs which directly affect the economy negatively. The deplorable condition of these road assets led the Government of Kenya to shift its emphasis from the construction of new roads to the rehabilitation and maintenance of the existing road network using the maintenance strategy known as the Roads 2000 Strategy. The strategy aims to improve road maintenance and construction by introducing appropriate technology on a road network basis for the selective rehabilitation, spot improvement and maintenance of prioritised links. The strategic goal of the R2000 program is to bring the rural road network of Class D, E, and special purpose roads including parts of the unclassified network to a maintainable standard and ensure that KRB Road Maintenance Levy Fund (RMLF) resources are used to maintain the maintainable and recently improved road network. This study aimed to assess the success and impacts of the R2000 program in Central Kenya. Roads constructed under the three batches of phase two were investigated to establish the current condition of the roads. The present serviceability was assessed and compared to the design life of the roads. The condition survey investigated the traffic status, surface and structural conditions. All the data from these studies were analysed using the appropriate methods and the results were used to make a valid conclusion on the performance of the completed low-volume sealed roads. The major defects on the roads were noted and examined closely to determine the extent and cause of the defects. Such defects included pothole formation, delamination of pavement layers, longitudinal, transverse and crocodile cracking, encroachment of vegetation onto the carriageway and stone loss. Each road had its own specific dominating defects, arising from different prevailing weather, traffic or material conditions and road use. Tests and measurements conducted on the pavements showed the completed low-volume sealed roads generally have a strong pavement that is adequate to carry 15-year design traffic. Axle load surveys showed the 10 and 15-year design traffic classes for completed roads still fall within the expected low-volume sealed roads traffic classes. The roads surveyed generally had good to very good side drainage. The defects observed in the majority of the roads such as cracks, aggregate loss, edge breaks, rutting and potholes, among others, were only limited to the surfacing
Power Coordination based Efficient Resource Allocation for Device-to-Device Communication in 5G Networks

Published: October 2022

Device to device communication for mobile networks establishes connections between parameters of mobile devices. As the number of D2D connections and resources are increasing, optimization of power allocation and spectrum feasibility is required. Most of the proposed algorithm schemes for resource allocation support slow-moving D2D terminals in a cellular network, therefore causing huge amount of signaling loss and reducing the efficiency of the cellular network. In energy and spectrum efficiency for the wireless network to meet the power requirement in D2D communication for better resource allocation in upcoming 5G technology is required. The proposed approach outplays the older power distribution approach using MATLAB simulation. The optimal allocation of resources and spectrum can enhance the system throughput with resource allocation techniques. D2D nodes not only perform better frequency resources but also provide better energy-efficient communication by using power control.
