Utilizing Heterogeneity Parameters in the Node Distribution for WSN Lifetime Enhancement
Authors:   Department of Electronics and Communication Engineering, Institute of Engineering and Technology,  Dr Ram Manohar Lohia Avadh University, Ayodhya, Uttar Pradesh, India, Gupta Shivam
Published: July 2023

In recent years, a number of steering conventions have been put out to increase the robustness, fault tolerance, latency, robustness, and dependability of Wireless Sensor Networks (WSN).A crucial component of steering conventions is determining the WSN's vitality requirements and extending its lifespan. The traditional bunch-based directing conventions of least transmission- vitality, direct transmission, multi-jump steering, static bunching, and direct transmission have all been proposed as ways to improve upon them. The most well-known WSN convention is Low-Energy Adaptive Clustering Hierarchy (LEACH), which is one of the group-based conventions. By incorporating a variety of LEACH components for both homogeneous and heterogeneous situations, we have attempted to expand the LEACH in this undertaking. We have proposed Hand Drain Stage 1 by introducing fit bunch head decision plan and particular sending force levels for Filter in homogeneous climate. However, a homogeneous environment's energy-saving plan is inappropriate for heterogeneous environments. Stable Political race Convention (SEP) is the component heterogeneous controlling show. To determine which hub has the most remaining power, SEP relies on weighted decision probabilities for each hub. Using a variety of approaches to correspondence (from CH to sink) for both advanced and common hubs, we propose Hand LEACH Phase 2. We demonstrate, through recreation, that Hand LEACH is more energy-efficient and outperforms LEACH in both homogeneous and heterogeneous settings in terms of system lifespan. Keywords: Data aggregation, Leach Protocol, Heterogeneous system, Dynamic cluster head rotation, and WSN.

Published: July 2023

Este artigo tem por objetivo expor detalhadamente como é o processo de fabricação de uma prótese mecânica funcional através de manufatura aditiva, conhecida como impressão 3D, para indivíduos que nasceram com má formação congênita, que perderam parte ou um membro completo do corpo, evidenciando essa alternativa como viável para a produção de dispositivos, visando alcançar as diretrizes de baixo custo, capacidade de customização alta, fácil manutenção e baixo tempo de produção, mas mantendo características importantes como resistência mecânica, baixo peso e durabilidade. Verificou-se durante a elaboração deste artigo que essa tecnologia ainda é pouco disseminada e possui obstáculos a serem superados, no entanto, é possível notar que, na última década, a prótese tem se tornado mais popular e tem seu acesso facilitado para pessoas de poder aquisitivo menor devido, principalmente, as ONGs e as plataformas de código aberto que viabilizam a produção de equipamentos e peças por indivíduos com pouco conhecimento técnico na área. Desse modo, esse processo produtivo se mostrou viável para concepção de próteses possuindo vantagens no quesito financeiro, mas também gerando inclusão social e autossuficiência para essas pessoas.

Published: July 2023

Youth unemployment is a global concern, attributed among others to lack of appropriate skills. Skills-focused education has been found to be an appropriate tool to fill the void. Indian Council of Agricultural Research heeded to this by introducing a programme in 2006 named Experiential Learning Programme the aim which was to equip undergraduates with entrepreneurial skills. The programme has been running for a decade since its inception, hence its evaluation comes at a rightful time. An ex-post facto study aimed at finding out among students and teachers how useful the programme had been in imparting entrepreneurial skills and competencies as well as to enable students to go through all entrepreneurial education stages was conducted in six agricultural universities in North India. The findings revealed that the programme was perceived useful by both students and teachers in imparting entrepreneurial skills, entrepreneurial competencies and allowed students to go through all stages of entrepreneurial education. Significant differences of usefulness of the programme as perceived by students from different disciplines were noted. Generally there were significant differences on perceived utility on the basis of personal characteristics of respondents, except for students’ sex and age. Students had little intention of venturing into self-employment, whereas teachers indicated that none of their graduates had established an enterprise. Even though the programme had been perceived useful in equipping graduates with the necessary entrepreneurial skills and competencies, graduates were not yet motivated to venture into self-employment. Therefore, there is need to review the programme and provide start-up fund at institutions which can assist students to go through all stages of entrepreneurship education as well as lure graduates into self-employment.

Published: July 2023

Segmental bridge construction is very common in Pakistan. However, the impact ofstructural system changes before and after the completion of segmental bridge construction is achallenge and major concern for construction stakeholders. Therefore, in this study, construction stageanalysis was performed for balanced cantilever construction technique to check the safety andserviceability of the bridge. Through time dependent analysis, considering the construction sequenceand creep deformation of concrete, structural responses related to the member forces were reviewed.Moment reversal was observed in the cantilever segments near the face of the pier. Therefore,maximum compressive and tensile stresses were observed in the top and bottom fibers of the girder,respectively. These stresses were within the AASHTO LRFD limits for construction stage loads.Results demonstrated that the creep moment redistribution started when the structural system changedfrom statically determinate to indeterminate stage. Furthermore, it was concluded that the timedependent deformation of concrete was the governing factor in order to achieve the final designmoments.

AN EFFICIENT ALGORITHMIC SOLUTION FOR HIGH PAYLOAD GOOD IMPERCEPTIBILITY HYBRID IMAGE STEGANOGRAPHY
Authors: A. Murtaza
Published: July 2023

A hybrid steganographic technique has been proposed to enlarge the size of secret message and to hide several images in one cover image. Initially, the secret images were compressed using JPEG 2000 before embedding them to the cover image. Second least significant bit plane of cover image was entirely replaced by secret message while tri-ways-pixel-value-differencing (TPVD) was used to hide secret message in remaining seven-bit cover image. The quality of stego image was enhanced by residual image coding (RIC). The cover image was divided in four sub-images, three of them provided cover for secret message using proposed technique while fourth sub-image was used to embed RIC of stego image using only TPVD, to ensure better quality in terms of peak signal to noise ratio (PSNR). Proposed technique provided the opportunity to transmit secret data without detection by different steganalysis techniques like dual statistics steganalysis. Experimental results verified that proposed technique achieved high payload with better image quality than TPVD scheme.

Authors: B. Zeb
Published: July 2023

Calcium precipitation and biofilm formation in halophilic bacteria were investigated in the current study. The strain SMK (Bacillus licheniformis) was isolated from plant rhizosphere and and AQ-1 (Alcaligenes faecalis) from marble crushing soil in Lahore. Bacterial growth, biofilm formation and CaCO3 precipitation of both strains was determined under varying stress (pH, temperature, agitation and salinity). Soil aggregation was investigated under salt stress (NaCl and MgSO4). Results showed that pH 8.0, temperature 42°C, 1.5 M salt (NaCl and MgSO4) stress without agitation was favorable for biofilm formation. Both strains were able to precipitate CaCO3 in media specially at margins of colonies in AQ-1. Effervescence of crystals with addition of concentrated HCl showed confirmatory results. Stereomicroscopic analysis of aggregates in inoculated soil and sand showed precipitation under salt stress. SMK (Bacillus licheniformis) showed high aggregation in soil. From the results, it was concluded that these indigenous strains have potential for sustainable agriculture by improving disturbed soil.

Published: July 2023

The leguminous crop chickpea (Cicer arietinum L.) has a great potential for nutrition, antioxidants, proteins, lipids, and carbs. Due to concerns with soil salinity/sodicity and climate change, the area used for chickpea cultivation is shrinking daily and the overall yield has decreased. Ten varieties of chickpea were subjected to salinity stress in a petri dish at four different NaCl concentrations: 0 mM, 50 mM, 100 mM, and 150 mM in a controlled condition experiment. The findings of the experiment revealed that Chattan and KK-1 do not survive under salinity stress. While Punjab-2008 and KK-2 demonstrated strong resilience to salinity stress. The results showed that at 0 mM of NaCl, KK-2 and Punjab-2008 had the highest germination rates (99%), followed by Bittle-98 and CM-98 (98%) The Chattan and KK-1 do not exhibit any germination at 150 mM NaCl. The data showed that Fakhr-e-thal had the smallest Radicle length (0.05 cm) at 150 mM NaCl, whereas Bhakkar-2011 at 50 mM NaCl had the largest Radicle length (4.90 cm). In comparison to 0 mM NaCl, the plumule length (cm) of the various chickpea genotypes showed that Bhakkar-2011 had the longest plumules (3.09 cm), Chattan had the shortest (0.80 cm), and KK-1 had no values at the greatest salinity levels. It is therefore concluded that increasing salinity badly affects the germination and growth in chickpea, but this stress can be mitigated by using salinity resilient genotypes.

Published: July 2023

A tecnologia blockchain tem revolucionado diferentes setores de mercado pela sua característica de transparência e imutabilidade dos dados gravados na rede entre os participantes. No setor de desenvolvimento de produto, diversas propostas têm sido realizadas como forma de ideação de soluções de blockchain para o apoio na área. Por ser uma tecnologia relativamente nova, não se tem revisões bibliográficas sistemáticas (RBS) voltadas a esse assunto de forma a apresentar de maneira sistematizada os resultados destas propostas, nem a classificação do nível de maturidade de cada proposta. Sendo assim, este trabalho, de cunho qualitativo e quantitativo, apresenta uma RBS utilizando das bases de dados internacionais para identificação das aplicações Blockchain na área do Processo de Desenvolvimento de Produto (PDP). O trabalho conta ainda com caracterização e classificação de cada aplicação encontrada, por meio da atribuição de categorias de análise e avaliação levando em consideração o Nível de Prontidão Tecnológica (TRL). A pesquisa mostrou que existem trabalhos relevantes na área que propõem ideias visando maior controle, segurança e transparência de dados no setor, contudo, encontrando-se ainda em estágios iniciais de pesquisa e teste.

Published: July 2023

Apresentamos, aqui, a descrição de um Ambiente de Programação, onde é possível fazer programas modulares com mistura de linguagens. No Ambiente, definimos uma Linguagem de Configuração, cujo principal objetivo é juntar os trechos de código em linguagens diferentes. Especificamos critérios para viabilizar essa mistura, que incluem a definição de uma Máquina Abstrata e algumas ferramentas. No momento, várias áreas de estudo estão abertas neste trabalho. A compatibilidade de tipos das diferentes linguagens, a definição da Linguagem de Configuração e à passagem de objetos entre os trechos de código escritos em linguagens diferentes são algumas delas. Apresentamos, também, alguns resultados sobre a passagem de objetos entre partes de um programa multi-linguagem e damos uma idéia geral do processamento de um programa neste Ambiente.

The Role of Opportunistic Behaviour in Specification Comprehension
Authors: Simplicio Filho Francisco
Published: July 2023

Opportunistic behaviour, which is characterized by shifts between partial solutions and desviations from planned actions, has been identified as legitimate and expected behaviour during software specification understanding. In contrast to goal-oriented behaviour, opportunistic behaviour proceeds without support of a method or general problem solving plan. Nevertheless, about half of the understanding behaviour has been characterized as opportunistic. So, it cannot be ignored in designing methods and tools for supporting specification building and understanding. This paper presents an engineering model of cognitive behaviour in specification understanding. It focuses on the control mechanisms that drive opportunisticand goal-oriented behaviours. The proposed model is based on an interpretation of an established psychological model and described in terms of a set theoretical visual formalism, the stategraph, able to represent concurrent and distributed components. As a conclusion, in contrast to the view in which opportunistic behaviour is described as plan violation, the model suggests that opportunistic behaviour does not totally rule out goal-oriented behaviour. A number of understanding activities can operate in parallel and to some extent, this enables the cognitive system to keep the course of actions according to plan while undertaking other cognitive activities. The model specifies the mechanisms that underlie this concurrence.

Published: July 2023

A preservação de todas as espécies de seres vivos é fundamental para a manutenção do equilíbrio no ecossistema, logo denunciar qualquer delito que infrinja a fauna e flora pode ajudar na preservação da mesma. No entanto, observou-se a falta de informação da população quanto às providências a serem tomadas quando identificam um crime ou irregularidade ambiental. Portanto, o objetivo deste trabalho foi desenvolver uma aplicação móvel que facilite a realização de denúncias de crimes ambientais contra a fauna no Brasil, pois os aplicativos contribuem na aquisição de informações e desburocratização de diversas atividades dos usuários. O aplicativo irá direcionar as denúncias diretamente ao instituto responsável, a fim de atender mais rapidamente a denúncia dos usuários.

Published: July 2023

É comum o uso de sensoriamento remoto para compreender a dinâmica de desmatamentos. Entretanto, a obtenção e processamento dessas imagens não é uma tarefa trivial, além de haver a dificuldade de ter áreas validadas de desmatamento. Para resolver esse problema este trabalho apresenta o Remote Sensing Deforestation Dataset (RSDD) que contém dados tabulados e imagens de áreas afetadas pelo desmatamento validado por um órgão Estadual. O RSDD possui um tamanho menor que 1% em relação às imagens originais de sensoriamento remoto, proporciona a redução de esforços em futuras pesquisas e pode servir como uma fonte comum para ser utilizada como benchmark em soluções de aprendizado de máquina.
