This presents many opportunities for individuals, businesses, and remote communities. The advantages of this connectivity have been brought to the fore by COVID-19, as technology and the Internet kept the world connected and functioning. However, in Africa, although much has been done on connecting the unconnected, there remains rural underserved communities. Notwithstanding the benefits of technology and the Internet, the cyber-safety and cybersecurity of those communities living on the fringes of society – rural underserved communities – is unknown. Consequently, many researchers, noting the benefits of technology, have embarked on ICT for Development projects (ICT4D). However, community based ICT4D projects have been failing due to myriad of factors. Some such factors are engagement misalignment, cultural faux pas’, communication, power dynamics and community-buy-in of end-products. With the propensity to circumvent the shortcomings indicated above, Participatory Design (PD) processes may be utilized. Co-design extends PD by allowing researchers and participants to be equals in the creation of solutions to problems contrary to traditional research approaches, that abstract researchers from the community within which they work. As an effort to address these challenges, we present a co-designed community engagement protocol (co-CEP) for rural underserved communities in Northern (Oukwanyama), Namibia. This study was qualitative, guided by Ubuntu and Uushiindaism tenets of trust, neighbourliness, respect, familiarity, hospitality, and collective unity as pillars of fostering communication within 4 villages in Oukwanyama, Namibia. The aim was to understand the concepts of how information flows in order to get engagement from community members for cybersecurity research. We held 4 co-design sessions in 4 villages, with each feeding into the next. The presented co-CEP comprises of 13 elements that are key to successful community engagement within community-based technology projects, especially cybersecurity research. The co-CEP is part of a research study on co-designing cybersecurity practices with rural underserved communities.","PeriodicalId":46518,"journal":{"name":"JOURNAL OF INFORMATION & OPTIMIZATION SCIENCES","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70470263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This makes commercial banks need to bear more risks when providing loans to small, medium and micro enterprises than large enterprises. Big. When commercial banks do not have credit records of certain small, medium and micro enterprises, this will increase the risk that banks need to bear when lending to these small, medium and micro enterprises without credit records, and will also increase the difficulty of credit loan for small, medium and micro enterprises in commercial banks.First of all, we should comprehensively analyze the credit risk of enterprises, establish the TOPSIS comprehensive evaluation model, and then establish the constraint conditions according to the data given by the topic, calculate the interest rate of bank loans to each type of enterprises, so as to determine the bank’s credit strategy. The paper seeks the bank’s credit strategy for these enterprises when the annual total amount of credit is fixed. We use AHP (Analytic Hierarchy Process) to normalize the credit rating, and then get the relevant data ranking of enterprises with credit records through TOPSIS comprehensive evaluation model. Through cluster analysis, we divide them into nine categories, and make the optimal credit strategy from the perspective of interest rate and credit line.","PeriodicalId":46518,"journal":{"name":"JOURNAL OF INFORMATION & OPTIMIZATION SCIENCES","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70469209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proper identification of plants forms the most important phase as it leads to usage of plants for various purposes. In this paper, we have manually collected about 30 leaves per species belonging to five medicinal plant species. The dataset was created using the scans of the adaxial and abaxial sides of the leaves. As the small number of images makes it difficult for the Convolutional neural network to learn the features, we have augmented the dataset using Deep Convolutional Generative Adversarial Networks (DCGAN). This paper shows that the low-quality images obtained by the scanner could be effectively augmented using the DCGAN thus increasing the variance in the dataset. A comparison of proposed versions of deep learning models namely VGG16, ResNet50 and DenseNet 121 is presented. To validate the results obtained, 5-Fold-Cross validation was used.","PeriodicalId":46518,"journal":{"name":"JOURNAL OF INFORMATION & OPTIMIZATION SCIENCES","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70469305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the basis of the report given by UNO India was placed  at 131th rank in terms of Human Development Index (HDI) but compared with in the less developed countries the index is very little low. From the days of independence the Government of India has launched various programmes and policies to improve their working efficiency but the Government was not able to achieve the desired results. There were many more policies ensuring better productive workforce to increase their standard and quality of the production process so as to achieve the better results. In Indian context these programmes like social security and compensation policies not only safeguard the interest of the working class but are also providing a fair and competitive wages. Proper HR policies are needed so as to tap their ful working capacity and also to improve the status of the firm. More precisely the working class in India has drastically faced many challenges and risks under the globalization period.

Small numbers of processors, a frequent feature of current multi-core systems, are ideal for future generation of CPUs, where automated parallelization succeeds on shared space architectures. The multi-core compiler optimization platform CETUS (high-level to high-level compiler) offers initiates automatic parallelization in compiled programmes. This compiler’s infrastructure is built with C programmes in mind and is user-friendly and simple to use. It offers the significant parallelization passes and also the underlying empowering techniques, allows source-to-source conversions, and delivers these features. This compiler has undergone numerous benchmark investigations (techniques) and approach implementation iterations. It might enhance the programs’ parallel performance. The main drawback of advanced optimising compilers, however, is that they don’t provide runtime details like the program’s input data. The approaches presented in this paper facilitatedynamic optimization using CETUS. The large amount of proposed compiler analyses and modifications for parallelization is the last point. To research the behaviour as well as the throughput gains, we investigated both non-CETUS based and CETUS based parallelized program features in this work.","PeriodicalId":46518,"journal":{"name":"JOURNAL OF INFORMATION & OPTIMIZATION SCIENCES","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70469683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chauhan","doi":"10.47974/jios-1342","DOIUrl":"https://doi.org/10.47974/jios-1342","url":null,"abstract":"Social media for news utilization has its own pros and cons. There are several reasons why people look for and read news through internet media. On the one hand, it is easier to access, and on the other, social media’s dynamic content and misinformation pose serious problems for both government and public institutions. Several studies have been conducted in the past to classify online reviews and their textual content. The current paper suggests a multimodal strategy for the (FND) task that covers both text and image. The suggested model (FakeExpose) is created to automatically learn a variety of discriminative features, instead of relying on manually created features. Several pre-trained words and image embedding models, such as DistilRoBERTa and Vision Transformers (ViTs) are used and fine-tined for the best feature extraction and the various word dependencies. Data augmentation is used to address the issue of pre-trained textual feature extractors not processing a maximum of 512 tokens at a time. The accuracy of the presented model on PolitiFact and GossipCop is 91.35 percent and 98.59 percent, respectively, based on current standards. According to our knowledge, this is the first attempt to use the FakeNewsNet repository to reach the maximum multimodal accuracy. The results show that combining text and image data improves accuracy when compared to utilizing only text or images (Unimodal). Moreover, the outcomes imply that adding more data has improved the model’s accuracy rather than degraded it.","PeriodicalId":46518,"journal":{"name":"JOURNAL OF INFORMATION & OPTIMIZATION SCIENCES","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70470026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four CNN models are discussed at different depths to understand how the accuracy of identification can be improved and the impact of hyperparameters namely batch size and number of epochs have on the accuracy of identification. The four models have been evaluated on two freely available leaf datasets: Flavia and Swedish. To reduce overfitting, data-augmentation and Early Stopping callback has been applied.
