The development of edible films applied to fruits and vegetables postharvest have generated recent advances regarding the synergistic effect of components on the shelf life of products. Currently, there are edible films made by combining several biopolymers, including chitosan, starch, pectin, alginate, among others. The application of physical barriers, such as films, on the surface of fruits can regulate the permeability to O2, CO2, and water vapor, delaying the natural process of physiological maturity. The use of films also improves the mechanical properties of horticultural products, which are essential in handling them. In the present work, films based on chitosan (antimicrobial agent) and pectin (gelling agent) as a biopolymer matrix, as well as glycerol (plasticizer) and calcium chloride (cross-linking agent), were prepared. The effect of adding the crosslinking agent on the film properties was evaluated by infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and dynamic viscosity testing.

Authors: Sanecki Henryk , Czauderna Tomasz
Published: December 2022

The article describes the structure and principles of operation of a drive system used in some low-floor trams. The system consists of electric motors, gear transmissions as well as hollow shaft s and four-linkage couplings causing the wheels to move. During the study, a dynamic model was built and the parameters needed to carry out a simulation were determined. NGT6 low-floor tram wagons operated by MPK S.A. Cracow were used as examples of existing vehicles. Due to the lack of available data, part of the work was devoted to determining mass moments of inertia of drive system components using an experimental method of torsional vibrations of a string. In subsequent chapters, a mathematical model was developed and a tram start-up simulation was performed based on specific parameters of the individual system components. Some of the results were presented in the form of graphs. Keywords: tram riding simulation, mathematical model of dynamics, start-up, mass moments of inertia, method of torsional vibration of string

 Cryptocurrencies acquire user confidence by making the whole creation and transaction history transparent to the public. In exchange, the transaction history accurately captures the complete range of user activities related to cryptocurrencies. In this paper, the use of data mining methods in Bitcoin transactions is analyzed and summarized. Cryptocurrencies, similar to the well-known Bitcoin, were targeted to ensure transaction security and privacy and overcome the drawbacks of traditional banking systems as well as other centralized systems. We also conduct a thorough analysis of the literature on the challenges and applications of electronic currencies. We outline the evolution of digital currency from electronic cash to cryptocurrencies and put the spotlight on the methods used to increase user privacy. We also highlight security threats in the existing cryptocurrency systems that jeopardize the privacy of Bitcoin users. Finally, we identify several research gaps and trends that need to be looked at further.  
Influence of channel fading and capture for performance evaluation in vehicular communications
Authors: Shah A F M Shahen , Karabulut Muhammet Ali , Ilhan Haci , Tureli Ufuk
Published: December 2022

Autonomy and intelligent transportation systems (ITS) have recently shown an increased interest in vehicle ad hoc networks (VANETs). Additionally, the impending 5G and 6G technologies will result in substantial advancements for VANETs. IEEE 802.11p summarizes specifications of physical (PHY) and medium access control (MAC) layers for VANETs. Existing analytical methodologies require improvement despite the fact that performance assessments of IEEE 802.11p MAC have been carried out. Bit error and channel capture influence performance of vehicular communications in real-world transmission. These effects are investigated separately in previous works. In this paper, an extensive study is provided which integrates these two major factors. In VANETs, the influence of channel fading and capture on IEEE 802.11p is investigated analytically using a Markov chain model. For Nakagami-m, Rayleigh, and Rician fading channels, performance impacting factors are taken into account, and relationships between parameters as well as performance metrics are derived. The probability of unsuccessful and successful transmission, outage probability, probability of frame capture, throughput, bit error rate, and delay terms are attained. Moreover, simulation results are provided which verify analytical studies.

Published: December 2022

The main contribution of this paper is providing low complexity precoding design for RSMA with low complexity streams. We consider hierarchical streams and interference nulling to simplify choosing streams and precoding design, respectively. The paper mainly revolves around precoding design to maximize sum rate. Particularly, we formulate a convex problem for the upper bound of sum rate maximization problem and examine the cases where the upper bound problem has the same solution as the sum rate maximization problem. In addition, we propose a two-stage algorithm to design precoding based on interference nulling and signal-to-noise ratio maximization.

Published: December 2022

With the development of lung diseases and the wide application of lung ultrasound (LUS), the independent analysis of various indicators in LUS images are of great significance in clinic. In this paper, we proposed a quantitative and qualitative method for extracting, analyzing, and scoring pleural lines with different lesions in LUS images. The extraction module was composed of the customized cascaded localization and segmentation models based on convolution and multilayer perceptron. The analysis module used eight textural and three morphological parameters to quantitatively analyze the features of two different output images from the localization and segmentation models, respectively. The scoring module adopted four supervised machine learning classifiers including support vector machine, k-nearest neighbor, random forest, and decision tree to qualitatively evaluate pleural lines with different severities in LUS images. The experiments were performed on the 5390 LUS images (i.e., segmentation: 1620, scoring: 3770) acquired from Coronavirus Disease 2019 pneumonia patients with convex ultrasound probes. Experimental results showed that the proposed line extraction method can accurately achieve the localization and segmentation of pleural lines. The support vector machine classifier with combining texture and morphological features as input achieved optimal scoring performance with the accuracy, sensitivity, specificity, F1 score, and AUC being 94.47%, 97.31%, 94.50%, 0.9457, and 0.9822, respectively. Compared with other models, it also proves that the proposed method has better scoring performance. Thus, the proposed method has great application potential for clinical application. 
Quad-band GSM/GPRS Enabled Low-Power Sensor Node Design For Outdoor IoT Applications
Authors: Maduranga Pasan
Published: December 2022

People have become increasingly aware of the environment in which they live in recent years. This awareness has prompted the development of a reliable environmental monitoring system. This paper presents an energy-efficient and low-power sensor node that could be used for outdoor Internet of Things (IoT) applications to monitor real-time environment conditions such as humidity and temperature remotely. The proposed sensor node could directly connect with a cellular base station over GSM/GPRS quad-bands 850MHz,900MHz,1800MHz, and 1900MHz without needing any Access Point(AP) in the network. The sensor node consists of a central controller based on Atmega328, a communication module on SIM800, DHT22 temperature, and a humidity sensor with a solar-powered charging system. The system is specially designed for robust IoT outdoor applications such as environment monitoring in wilds, large-scale farms, forests, etc. For optimal usage of the power of the battery, an energy-saving mechanism is proposed based on deep sleep scheduling, thus considerably reducing the power consumption and prolonging the up-time of the sensor node. 
Content characterization for live video compression optimization
Authors: Martini Maria
Published: December 2022

Compressing video sequences with different content complexity results in different bitrates for the same quality level or in different quality levels for the same bitrate; for instance it is well known that content with high spatial complexity and/or high motion requires high bitrates for compression with adequate quality. To address this, per-title optimization is used recently (e.g., by Netflix) to generate appropriate rate-quality representations for different Video on demand (VoD) content to be streamed via adaptive video streaming. However, this cannot be adopted for live video streaming as it requires encoding (multiple times) each video content. Spatial Information (SI) and Temporal Information (TI) have been often used as indicators of video complexity, for instance for preparing and describing content for video quality assessment tests, and for rate-distortion modeling. However, it has been questioned recently if different metrics could lead to a better estimation of ”compressibility” of video. In this paper we compare existing and proposed metrics in terms of their ability to estimate ”compressibility”. This supports quality-rate estimation and the possibility to create appropriate ”quality ladders” (different quality representations) for adaptive live video streaming. We observe in particular that metrics related to the variance of pixel values provide a good estimation of compressiblity for the considered datasets.

Randomized Tensor Robust Principal Component Analysis
Authors: Mohammadpour Salut Mohammad , Anderson David
Published: December 2022

Removing noise from hyperspectral images can be very beneficial for improving classification accuracy. Recently, tensor robust principal component analysis (TRPCA) has been successfully employed to reduce noise in hyperspectral images. In TRPCA, a minimization involving a tensor nuclear norm and a ℓ1-norm is employed to separate the low-rank hyperspectral image from the sparse noise. Tensor nuclear norm minimization is solved by iteratively performing tensor singular value thresholding (T-SVT). However, TRPCA possesses high computational complexity primarily due to the implementation of the T-SVT operator. The conventional approach for T-SVT is first to perform full tensor singular value decomposition (T-SVD), and then to shrink the singular values of the frontal slices in the frequency domain. However, when the solution of tensor nuclear norm minimization is a low-rank tensor, a good strategy is to incrementally find the singular values until they fall below the threshold. In this letter, we propose a randomized blocked algorithm for computing tensor singular value thresholding, and we leverage the compression attained by the fast Fourier transform (FFT) to accelerate TRPCA. Numerical experiments indicate that our method is significantly faster performing than TRPCA via the full T-SVD while maintaining classification accuracy.

Authors: Hidayah Lia , Sunarsih Sunarsih
Published: December 2022

Underpricing is a condition where the stock price of a company when conducting an Initial Public Offering (IPO) is below the stock price when it is in the secondary market. In Indonesia, shares are divided into two types, namely Islamic shares and non-Sharia shares. This study aims to determine the effect of underwriter reputation, investment risk, profitability, financial leverage, and company size on the level of underpricing of Islamic stocks and non-Islamic stocks. The sampling technique used is purposive sampling. The analytical method used is multiple linear regression with cross section data type. The results of the study found that there were differences that affected the underpricing of Islamic and non-Islamic stocks. In Islamic stocks, underpricing is only influenced by financial leverage, while underpricing for non-Sharia stocks is influenced by investment risk and company size. This study provides an overview to investors who have the aim of investing in companies that are IPOs for profit so that they carefully consider the influence of underwriter variables, investment risk, company size, financial leverage, and profitability. For companies, this research provides an overview for companies so that they can make the right decisions in offering optimal share prices. And for further researchers, these findings can be used as a reference to be able to do better research in the future.

Authors: Silva Santos Samir Sallen , Angelo Júnior Lúcio Alves
Published: December 2022

La contratación pública representa parte relevante del gasto de los países. En Brasil, puede alcanzar alrededor de un 12% de su Producto Nacional Bruto (PNB). Según la Convención de las Naciones Unidas contra la Corrupción, los contratos públicos son instrumentos de gran importancia para lograr intereses colectivos, pero muy vulnerables a actos de corrupción y fraude causadores de daños al desarrollo económico. Recientemente han surgido las Tecnologías de Registros Distribuidos (TRD, o DLTs, por sus siglas en inglés), dotadas de características que pueden aportar beneficios significativos al sector público. Entre ellas, la garantía de inmutabilidad e integridad de registros múltiples y la desintermediación generada por un mecanismo de consenso entre ellos. Su uso permite la automatización de procedimientos a través de los denominados smart contracts en procesos de licitación pública, reduciendo posibles brechas a hechos ilícitos. Así las cosas, este trabajo examina algunas de las iniciativas europeas sobre dicha tecnología, el entorno jurídico brasileño y, al final, propone una reflexión sobre los primeros pasos hacia su implementación y las interacciones necesarias a una efectiva coordinación institucional para el uso de la blockchain por la administración pública en Brasil.

As compras realizadas pelo Governo Federal Brasileiro correspondem a  1,5% do Produto Interno Bruto nacional em média (R$ 119 bilhões em 2021). Além do grande volume de recursos, o processo de compras públicas é percebido como muito vulnerável a fraudes (OECD, 2018). Considerando a relevância, os valores e os riscos envolvidos a Controladoria-Geral da União criou a Analisadora de Licitações, Contratos e Editais (Alice) com o objetivo agregar valor à gestão pública com uma atuação preventiva e tempestiva em relação às compras públicas. O sistema coleta diariamente, de forma automática, informações sobre os processos em curso nas principais plataformas de compras públicas do Governo Federal, avalia um conjunto de riscos e emite alertas para direcionar a atenção dos auditores e dos gestores envolvidos a situações que fogem ao padrão referencial. É, portanto, uma ferramenta de Auditoria Contínua, com funcionamento de automação robótica de processos, que emite alertas sobre possíveis problemas em compras públicas. A Alice acumula resultados positivos cotidianamente. Já são mais de R$ 9,7 bilhões em compras suspensas a partir de suas indicações, apenas pela CGU. No caminho até o alcance desses resultados a CGU vivenciou grandes desafios descritos nesse relato. O ponto crucial para o sucesso da ferramenta foi a integração de seus resultados ao processo de trabalho ordinário da Casa, com forte patrocínio da alta administração. A ferramenta agora evolui para adição de mais funcionalidades que usam técnicas de inteligência artificial e para a agregação de novas bases de dados.

Buscou-se compreender de que forma a ciência de dados e as tecnologias de mineração e classificação de textos podem contribuir para uma melhor compreensão, agregada, dos pedidos de acesso à informação. A pesquisa utilizou dados dos pedidos de acesso à informação feitos à Prefeitura Municipal de São Paulo (PMSP), de 2012 a 2019, disponíveis no Portal de Dados Abertos da municipalidade, propondo a identificação e classificação das principais questões apresentadas. Os 39.369 textos dos pedidos de acesso submetidos à PMSP foram reunidos em um corpus e submetidos a análise por meio de Classificação Hierárquica Descendente (CHD). Nesse mesmo corpus foram inseridas cinco variáveis demográficas para cada pedido, que foram submetidos a uma rotina padrão de pré-processamento de texto, selecionando 31.946 pedidos (81,16%) para análise pela CHD. Ao propor uma classificação de textos como uma metodologia para análise de dados textuais, reforçou-se um paradigma de que dados textuais não pertencem apenas ao campo qualitativo. Além disso, a consideração de apenas nomes, excluídos verbos e advérbios; e os adjetivos mais ocorrentes serem usados como parte de expressões, permitiu uma otimização do contexto dos pedidos, proporcionando classificar os dados textuais de maneira mais objetiva, mitigando o viés dos investigadores. Da análise por meio da Classificação Hierárquica Descendente resultaram sete classes: 1 - Bairros e distritos; 2 - Trâmite e documentos processuais; 3 - Contratações públicas; 4 - Mobilidade urbana; 5 - Família: saúde, educação e assistência social; 6 - Imóveis; e 7 - Concursos e cargos públicos. O artigo apresenta também outros estudos de caso relevantes para a pesquisa, com referências encontradas na análise de pedidos de acesso à informação , contribuindo para a compreensão de pedidos dos cidadãos de modo aglutinado e permitindo aos tomadores de decisões um melhor entendimento das demandas da sociedade, podendo resultar em políticas públicas mais focadas.

O objetivo do artigo é identificar as contribuições do controle social por meio de denúncias e representações na atividade de controle externo realizada pelo Tribunal de Contas do Estado de Santa Catarina. A pesquisa possui como objeto as representações e denúncias autuadas no TCE/SC no ano de 2020. Para sua compreensão, foram identificadas as decisões expedidas pela Corte de Contas em relação a tais processos. O presente estudo aplicou a pesquisa quantitativa, na medida em que forma observados os dados relativos aos processos de denúncias e representações autuadas no TCE/SC no ano de 2020, e também se utilizou da pesquisa qualitativa ao descrever a situação do contexto em que foi realizada a investigação e explicou as variáveis do fenômeno da participação social. Pôde-se perceber o nível de interação destas espécies de controle incidentes sobre a gestão pública que se inserem dentro do paradigma do Novo Serviço Público e das noções de accountability diagonal. Os principais resultados da análise se pautam na observação de que a maioria dos processos propostos pelo controle social possuem a temática envolvendo procedimentos licitatórios; são apresentadas majoritariamente por empresas privadas, em primeiro lugar, e em segundo lugar pelos cidadãos cidadãos; e se referem à esfera municipal em detrimento da esfera estadual. A interação entre o controle social e o controle externo, a partir da análise das denúncias e representações autuadas em 2020 no TCE/SC, são demandas que tratam de processos licitatórios que, em sua maioria, acabam sendo improcedentes, extintos ou não conhecidos.

Indonesia merupakan salah satu negara yang mengembangkan konsep Universal Health Coverage (UHC) pada sektor kesehatan yang diterapkan pada Sistem Jaminan Sosial Nasional (SJSN) melalui program Jaminan Kesehatan Nasional (JKN) yang dikelola Badan Penyelenggara Jaminan Sosial (BPJS) Kesehatan dengan tujuan sebagaimana tertuang pada Undang-Undang Republik Indonesia Nomor 40 Tahun 2004. Peserta JKN terbagi menjadi Penerima Bantuan Iuran (PBI) dan Non Penerima Bantuan Iuran (Non PBI). Penelitian ini, untuk menganalisis faktor yang mempengaruhi persentase kepesertaan BPJS Non PBI yang diharapkan dapat memberikan prediksi pengoptimalan. Pengoptimalan diperlukan karena, realitanya persentase kepesertaan BPJS Non PBI masih jauh dari target pemerintah, khususnya Provinsi Jawa Timur pada tahun 2017 hingga 2020. Walaupun mengalami peningkatan, di setiap Kabupaten/Kota Provinsi Jawa Timur terindikasi mengalami fluktuasi. Maka, dalam mengestimasi fenomena tersebut digunakan metode regresi data panel melalui pendekatan Fixed Eeffect Model (FEM) dengan alpha sebesar 5 persen. Maka, secara statistik diperoleh kesimpulan bahwa yang berpengaruh signifikan adalah persentase penduduk miskin dan Tingkat Pengangguran Terbuka (TPT).

Persentase penduduk miskin yang tinggi menunjukkan bahwa tingkat kemiskinan di suatu wilayah juga tinggi. Persentase penduduk miskin sering menjadi pembicaraan publik. Kenaikan ataupun penurunan presentase penduduk miskin tetap menjadi permasalahan di setiap daerah. Sehingga pemerintah daerah tetap berusaha untuk mengendalikan kesejahteraan daerahnya dengan melakukan perlindungan serta menyejahterakan kehidupan sosial dan ekonomi daerahnya. Naik turunnya persentase penduduk miskin ini dipengaruhi oleh beberapa variabel. Untuk mengetahui variabel-variabel tersebut dapat digunakan salah satunya dengan pendekatan regresi berganda. Akan tetapi, dalam permasalahan kemiskinan ini tentu dipengaruhi juga oleh keadaan sekitarnya. Hal ini menyebabkan kemungkinan asumsi residual independen tidak dipenuhi, sehingga analisis regresi dapat dikembangkan ke metode spasial area. Hasil analisis yang dilakukan menunjukkan bahwa selain dipengaruhi oleh variabel-variabel yang diduga berpengaruh, juga dipengaruhi oleh wilayah sekitar.
