Principal component analysis in long term assessment of total viable plate count of municipal water distribution network system in healthcare facility
Authors: Eissa Mostafa , Rashed Engy , Eissa Dalia
Published: April 2022

The microbial quality of water is a critical safety aspect that should not be overlooked, especially when considering human consumption in the facilities for healthcare and the treatment of health compromised populations. The present work aimed to study a municipal network for city water within a healthcare facility microbiologically. The implementation of multivariate analysis was conducted over collected data to decipher trends of the microbiological count of samples from different points-of-use. The statistical study involved an Eigenvalue determination, score graph, loading plot study and outlier diagram. Data showed clustering tendency with aberrant values could be observed. The first component appeared to be associated with bioburden density in the water. While the other component showed a link to the relative locations of the distribution points in the facility and the length of the water lines from the source feeding city water to a great extent. The two components explained more than 55% of the variations in data. A property that highlighted a strong agreement between the order of points-of-use in the loading plot with that of ratio factor which was obtained from the Total Viable Count over the hypothetical distance of sampling port from the reference feeding entrance. Thus, there was evidence of variation in the microbial quality affected by the biological stability of the water distribution system that needed attention and an improvement plan for better control of microbial content in city water to prevent possible excursions in the future. The study showed a valuable perspective approach for the quantitative examination of the microbiological stability of the municipal water distribution network system.

Authors: Naif Saad S. , Sulaiman Shian S. , Shukur Mohammed Hussein
Published: April 2022

There are many techniques of using routing protocols on Sensor Network's mobile nodes, yet failures can occur in Wireless Networks path. High mobility leads to slipping nodes in the routing table, causing packet loss; current protocols suggest using rediscover paths. Nevertheless, this process increases delay. This paper proposes a design of two different methods to select the shortest multipath and select the longest multipath to get different scenarios to Set Backup Routes on Sensor Network “SBSN” to avoid using rediscover routes by providing different paths and improve the performance and efficiency of a network depending on the method of packets processing declared in the Proposed System. The proposed technique merges An Ad Hoc On-Demand Distance Vector “AODV” and Multipath-Ad Hoc On-Demand Distance Vector “M-AODV”. Comparison of a delay in transmitting rate, loss of packets, and packet delivery ratio to ensure a network's transmitting performance and efficiency Achieves low broadcast redundancy. It avoids the challenges of establishing paths from low to high-mobility of nodes between a single source and destination.

Adsorption Models with the application of corrosion experimental data is a very popular mechanism to predict various inhibitive systems. The effective modelling and interpretation of adsorption isotherms reliably determine the level of accuracy of adsorption processes. This study aims to apply the adsorption models and inhibitive mechanism of Cucumber Peel Extract (CPE) and Cucumber Seed Oil (CSO) to corrosion of AISI 1007 steel grade in the saline medium using both the electrochemical (Tafel Polarisation) and non-electrochemical (Weight Loss) techniques. The chemical composition of AISI 1007 and the phytochemical properties of studied extracts were determined. Consideration was given to Langmuir and Dubinin-Radushkevich Isotherm models (D-RIM) to study the inhibitive properties of CPE and CSO on AISI 1007 steel in an aggressive medium. The result of inhibition efficiency from weight loss measurement showed maximum inhibitions of  94.44 % and 95.44 % with 1.0 g/L concentration of CPE and CSO respectively in sea water medium. The result of the studied extract at 25 ℃ in seawater showed that the corrosion current density of AISI 1007 steel decreased and increased in the inhibition efficiency with 87.33% and 94.67% for CPE and CSO respectively. The negative value of ΔGads was greater than 20 kJ/mol and was obtained as a result of electrostatic interaction between the adsorbed inhibitor molecules and the  ions/atoms on the metal surface. The studied inhibitors were confirmed to be mixed organic corrosion inhibitors type. The values of E and maximum surface coverage (θmax) for the two measurements are satisfactorily in acceptable agreement  as similar to the range of value obtained for inhibition efficiency.
Perceived Characteristics of Materials in a Product Aesthetics Context
Authors: DUMITRESCU Andrei
Published: April 2022

Materials possess a number of objective characteristics, the values of which can be determined experimentally. On the other hand, materials also have a number of subjective characteristics, such as perceived quality, perceived performance, and so on. These perceived features are very important in constructing the product’s aesthetics. The paper presents the results of three experiments performed to determine perceived characteristics (quality, performance, durability, modernity, and aesthetics) associated with four classes of materials (metal, plastic, wood, and ceramics). Computer-designed product models were used in the experiments. All products used in the experiment were low-tech. The design was  varied on three levels: minimal, elaborate, and exceptional. Differences in perception were found for each level of design. It has been found that the elaborate design improves the perception of the characteristics of the materials, but the  exceptional design has a negative influence on the perception. Plastics benefit greatly from the contribution of design, while wood (traditional material) is better perceived in the case of minimal design.

Authors: Andriani Nita
Published: April 2022

The economic downturn in Indonesia after Covid-19 pandemic can be perceived generally from Indonesia’s current situation in the second quarter in which a 5.3% decline is apparent. The decline has risen by 0.3% from 5% since the last 10 years. Naturally, the economic decline also occurred in Lumajang district where the economic growth reached up to 5.02% in 2018, then decreased to 4.77% in 2019. One of the ways that LMDH is doing to improve the economy of Senduro people in Lumajang is by empowering the community. Seeing the potential natural resources that Burno Village has, the LMDH and the local community are working together with Perhutani to create a Taman Siti Sundari attraction. The purpose of this study was to determine the concept of community economic empowerment carried out by LMDH in order to improve the economic welfare of the community around Taman Siti Sundari. The current study also aims at knowing the size of the economic growth amongst the community that resulted from the LMDH empowerment program in Taman Siti Sundari. The researchers employed descriptive qualitative for the research method. The primary data was taken from the interview data from the interviewees. Triangulation method was also employed to validate the data. The result showed that the concept of community economic empowerment carried out by LMDH was in accordance with Ibn Khaldun's theory of economic development. LMDH carried out the task by emphasizing the important role in the concept of development such as being ar-rijal (community), LMDH as a community that manages, having al-imarah (development) of Taman Siti Sundari, and having natural resources which become al-mal (wealth). For the amount of income from this attraction, the community is given entrepreneurial land and profitable job since the parking income alone gains IDR 51,000,000 / month.

Penggunaan internet yang pesat menciptakan suatu peluang bisnis bagi perusahaan, yaitu dengan munculnya e-Commerce. E-Commerce dikembangkan lagi menjadi jenis platform bisnis yang baru, yang dikenal sebagai e-Marketplace. E-Marketplace memungkinkan pengusaha kecil dan menengah serta individu sebagai konsumen akhir dapat memasarkan produk mereka secara internasional hanya dengan membuat sebuah toko online melalui website ataupun aplikasi mobile platform e-Marketplace tersebut. Perkembangan e-Marketplace di Indonesia masih memiliki kekurangan utama, yaitu kurangnya kepercayaan. Hal ini disebabkan karena masyarakat Indonesia, masih lebih mempercayai penjualan secara langsung. Selain masalah kepercayaan, e-Marketplace di Indonesia memiliki masalah di bidang keamanan karena belum ada payung hukum yang jelas menyangkut keamanan e-Marketplace. Penelitian ini menggunakan kuisioner dengan 30 pertanyaan yang dibagi menjadi 5 bagian berdasarkan Success Model System yang diciptakan oleh DeLone dan McLean, yaitu data responden, pertanyaan dasar mengenai e-Marketplace, penilaian responden terhadap kualitas sistem e-Marketplace, penilaian responden terhadap kualitas informasi e-Marketplace, penilaian responden terhadap kualitas layanan pada e-Marketplace, penilaian responden mengenai tingkat penggunaan e-Marketplace, dan penilaian responden mengenai tingkat kepuasan pengguna. Hasil penelitian yang diperoleh menunjukkan bahwa sistem e-Marketplace yang ada di Indonesia masih memiliki kekurangan dan keterbatasan yang membuat masyarakat belum dapat menggunakan e-Marketplace sebagai suatu sarana transaksi jual beli secara optimal.

Raking and Relabeling for Imbalanced Data
Authors: Park Seunghwan , Lee Hae-Hwan , Im Jongho
Published: April 2022

We consider the binary classification of imbalanced data. A dataset is imbalanced if the proportion of classes are heavily skewed. Imbalanced data classification is often challengeable, especially for high-dimensional data, because unequal classes deteriorate classifier performance. Under sampling the majority class or oversampling the minority class are popular methods to construct balanced samples, facilitating classification performance improvement. However, many existing sampling methods cannot be easily extended to high-dimensional data and mixed data, including categorical variables, because they often require approximating the attribute distributions, which becomes another critical issue. In this paper, we propose a new sampling strategy employing raking and relabeling procedures, such that the attribute values of the majority class are imputed for the values of the minority class in the construction of balanced samples. The proposed algorithms produce comparable performance as existing popular methods but are more flexible regarding the data shape and attribute size. The sampling algorithm is attractive in practice, considering that it does not require density estimation for synthetic data generation in oversampling and is not bothered by mixed-type variables. In addition, the proposed sampling strategy is robust to classifiers in the sense that classification performance is not sensitive to choosing the classifiers.

Convolutional Neural Network (CNN) inCOVID-19 Detection: A Case Study with Chest CT Scan Images
Authors: Hafiz Khandaker Nusaiba
Published: April 2022

Deep Learning, especially Convolutional Neural Networks (CNN) have been performing very well for the last decade in medical image classification. CNN has already shown a great prospect in detecting COVID-19 from chest X-ray images. However, due to its three dimensional data, chest CT scan images can provide better understanding of the affected area through segmentation in comparison to the chest X-ray images. But the chest CT scan images have not been explored enough to achieve sufficiently good results in comparison to the X-ray images. However, with proper image pre-processing, fine tuning and optimization of the models better results can be achieved. This work aims in contributing to filling this void of the literature. On this aspect, this work explores and design both custom CNN model and three other models based on transfer learning: InceptionV3, ResNet50 and VGG19. The best performing model is VGG19 with an accuracy of 98.39% and F-1 score of 98.52%. The main contribution of this work includes: (i) modeling a custom CNN model and three pre-trained models based on InceptionV3, ResNet50, and VGG19 (ii) training and validating the models with a comparatively larger dataset of 1252 COVID19 and 1230 non-COVID CT images (iii) fine tune and optimize the designed models based on the parameters like number of dense layers, optimizer, learning rate, batch size, decay rate, and activation functions to achieve better results than the most of the state-of-the-art literature (iv) the designed models are made public in [1] for reproducibility by the research community for further developments and improvements.

Convex Relaxation of Optimal Power Flow for Hybrid LCC-HVDC and AC Power Grids
Authors: Liang Hongyuan , Li Zhigang , Zheng Jiehui , Wu Q. H.
Published: April 2022

Line-commutated converter (LCC)-based high-voltage DC (HVDC) systems have been integrated with bulk AC power grids for the interregional transmission of renewable power generation. The nonlinear HVDC model brings additional nonconvexity to the optimal power flow (OPF) of hybrid AC-DC power grids. The convex relaxation of such an OPF model could be a remedy, which has been discussed by little work. In this paper, a convexification method for the OPF of LCC-based AC-DC power grids is proposed using second-order cone programing relaxation. A sufficient condition for the exactness of the proposed convex relaxation is proposed and proven. The properties, exactness and efficiency of the proposed model are verified in three numerical simulations. The simulation results demonstrate that a globally optimal solution of the original OPF can be obtained from the proposed relaxed model with high computational efficiency.
A comprehensive survey on the application of blockchain/hash chain technologies in V2X communications
Authors: Farran Hassan , Khoury David , Bokor László
Published: April 2022

The Vehicle-to-Everything (V2X) technology and protocols are the main cornerstones for advanced transportation and autonomous vehicle applications. V2X has several subsets, including Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication contexts. The main benefit of applying V2X technologies is increased safety by facilitating predicted warnings supporting automated driving and traffic applications. Wirelessly transmitted messages are the information sources; therefore, security is critical in V2X systems. The V2X exchanged messages are sent wirelessly and must fulfill the security requirements, such as integrity, authenticity, and privacy support. The messaging between vehicles and networks must be trusted. Lately, promising and proliferating blockchain/hash chain technologies have been introduced in V2X communications and cope with the cooperative vehicular applications security and related efficiency aspects. This paper provides a comprehensive survey about the V2X use-cases based blockchain/hash chain and introduces the available solutions and methods in this domain.
Batch-scheduling Data Flow Graphs with Service-level Objectives on Multicore Systems
Authors: Lévai Tamás , Rétvári Gábor
Published: April 2022

Data flow graphs are a popular program representation in machine learning, big data analytics, signal processing, and, increasingly, networking, where graph nodes correspond to processing primitives and graph edges describe control flow. To improve CPU cache locality and exploit data-level parallelism, nodes usually process data in batches. Batchy is a scheduler for data flow graph based packet processing engines, which uses controlled queuing to reconstruct fragmented batches inside a data flow graph in accordance with strict Service-Level Objectives (SLOs). Earlier work showed that Batchy yields up to 10x performance improvement in real-life use cases, thanks to maximally exploiting batch processing gains. Batchy, however, is fundamentally restricted to single-threaded execution. In this paper, we generalize Batchy to parallel execution on multiple CPU cores. We extend the analytical model to the parallel setting and present a primal decomposition framework, where each core runs an unmodified Batchy controller to schedule batch-processing on a subset of the data flow graph, orchestrated by a master controller that distributes the delay-SLOs across the cores using subgradient search. Evaluations on a real software switch provide experimental evidence that our decomposition framework produces 2.5x performance improvement while accurately satisfying delay SLOs that are otherwise not feasible with single-core Batchy.
Digesting the foreign. Food and Eating in the works of Tawada Yōko
Authors: Barbieri Francesco Eugenio
Published: April 2022

This paper aims at analyzing the representation of food and eating in seminal works by Japanese author Tawada Yōko. The first part of this contribution will analyze the connection between food and metamorphosis, focusing especially on Das Bad and Yogisha no yakōressha, works that belong to an earlier stage of the production of Tawada. The second part of this contribution will specifically inspect the representation and the metaphor of food in the works written in the aftermath of the 3.11 such as Kentōshi, Fushi no shima and the poem Hamlet no see.
Negotiating with the tradition: representations of fish in Alai’s fictional writing
Authors: De Grandis Mario , Costantini Filippo
Published: April 2022

Tibet has long been orientalized in fictional representations. Taking as a case study two texts by Alai, this paper investigates how a traditional Tibetan cultural trait–the fish taboo–is mobilized to complicate the representation of Tibetan culture. By describing the fish taboo Alai points at Tibet's cultural specificity, which in virtue of its exoticism can catch the attention of non-Tibetan readers. At the same time, however, Alai equips his characters with psychological depth, showing their contrasting inner emotions of attraction and repulsion toward fish. In this sense, Alai subtly points at the fallacies of flat representations of Tibet, thus dismantling them from within.

This paper discusses the cultural and linguistic mediation strategies involved in the compilation of a terminological tool aimed at facilitating the intercultural exchanges between Italy and China in the field of oenology, by taking the Dictionary of Italian wines and grape varieties (Italian - Chinese) (Bosc et al. 2019) as a case study. The main objectives of the dictionary compilation were the popularization of specialized wine language, the standardization of the names of Italian wines and grape varieties, and the translation of the Italian lexicographical definitions in Chinese. For this process to be effective in terms of intercultural communication and mediation, the negotiation of standardization and translation strategies needed to take into account the differences between the two cultures and languages involved as well as the constraints of the lexicographical genre. After delineating the historical background and presenting the purpose of the dictionary from the lexicographical perspective, the paper delves into the choices made in the compilation of the Chinese text.
Reduction of leaf tip burns of Ornithogalum dubium by controlling the temperature during bulb storage and greenhouse forcing to produce quality plants
Authors: Wu X. , Wang L. , Roh Mark
Published: April 2022

Production of quality potted Ornithogalum dubium Houtt. plants were investigated under multiple conditions: pre-planting treatment at 10, 16, and 22°C for 40 days from Sept. 21 (stage A; ST-A) during bulb storage and then bulbs were potted. After potting, post-planting treatment at 15/12, 18/15, and 21/18°C (day/night) during stage B for 35 days from Nov. 2 (stage B; ST-B), and at 15/12 and 21/18°C during stage C for 30 days from Dec. 7 (stage C; ST-C) during greenhouse forcing was applied. Leaf tissue analyses for macro- and micro-nutrients were performed to investigate the cause of leaf tip burn symptom (LTB). Three criteria for quality of the plants at flowering were established: (1) LTB occurs on less than 1.5 leaves per plant. (2) the number of days to flower is less than 115 days, the length of the third leaf counted from the crown (the junction of the shoot and roots) is shorter than 11.5 cm, and the width is narrower than 2.5 cm; the scape length is shorter than 15 cm, and there are more than 45 flowers. (3) the leaf spread and morphology (leaf spread) and the pattern of the scape curvature (scape growth) have a score of less than 1.5. The following conditions are optimal to produce quality plants based on these three criteria: (1) Pre-planting bulbs treatment was applied at 10 or 16°C during ST-A, and forcing was performed at 15/12°C during ST-B and 21/18°C during ST-C. These conditions accelerated flowering, produced straight scape growth and upward (erect) growing leaves, and yielded acceptable leaf length and width. (2) The incidence of LTB was minimal at 10°C or possibly 16°C during ST-A, and at 15/12°C in ST-B and at 21/18°C in ST-C during greenhouse forcing. Leaf tip burn symptom was observed in both young and old leaves and was caused by a high boron (B) concentration (218-230 ppm) and possibly a high zinc (Zn) concentration (155-159 ppm) in O. dubium. A low calcium (Ca) concentration was not the cause of LTB. Although LTB cannot be avoided, it can be minimized by temperature manipulation during pre- and post-planting phase to produce high quality potted plants.
Decreasing postharvest chilling injury of guava fruit by using melatonin treatment
Authors: Mirshekari Amin , Madani Babak
Published: April 2022

Guava fruit is a tropical fruit thus sensitive to the chilling injury. In this study the effects of melatonin (known to protect membrane integrity and to help to face abiotic and biotic stress) is evaluated for reduction of chilling injury during postharvest. Guava fruits were dipped into 10, 100 and 1000 μmol L-1 melatonin solutions, then kept at cold storage (10±1°C and 90% relative humidity) for 21 days. Several parameters including chilling injury, malondialdehyde content, electrolyte leakage and increased total phenolic compounds and antioxidant activity, phospholipase D and lipoxygenase activity were measured after treatment. Measurements were made every 7 days during the storage. Results showed that melatonin decreased chilling injury, malondialdehyde content, electrolyte leakage and increased total phenolic compounds and antioxidant activity compared to the control. Also, results indicated that chilling injury of guava fruit by using melatonin decreased through increasing integrity of membrane and reducing phospholipase D and lipoxygenase activity. Thus, melatonin can be a useful treatment for decreasing postharvest chilling disorder of guava fruit.

It is emphasized that the possession of modern scientific terminology by library and information specialists is an important component of their professionalism, and the formation of terminological culture is an important factor in professional training. The meaning of the term "term" and some of its characteristics are considered. The problem of foreign borrowings in the Ukrainian library and information terminology is paid attention. It is noted that the introduction of information and communication technologies in the library business primarily affected the processes of cataloging documents, so much attention is paid to the terminology of cataloging. The influence of the processes of globalization, integration and international cooperation on the state of the terminology of the library industry in Ukraine is considered. The issue of standardization of terminology is an important and relevant area of terminology, so one of the main tasks of standardization in the library and information field is to work on streamlining the use of terms. The need for normative regulation of the library and information sphere in accordance with international standards, development, harmonization and implementation of unified scientific terminology is noted. Some aspects and peculiarities related to terminology in connection with the introduction of a new international RDA standard, as well as the problems of implementation of this standard in Ukraine are considered. Emphasis is placed on the problem of harmonization and implementation in Ukraine of international standards in the field of library and information, which is an important factor on Ukraine's path to the European and world information space.
