Dynamic Tuning of the Controller Parameters in a Two-Area Multi-Source Power System for Optimal Load Frequency Control Performance
Authors: Gbadega Peter Anuoluwapo , Saha Akshay Kumar
Published: November 2020

Frequency control is becoming increasingly critical today due to the growing size and changing structure of complex interconnected power networks. Scaling up economic pressures for efficiency and reliability of the power system has necessitated a requirement for maintaining system frequency, and tie-line power flows as close as possible to scheduled values. High-frequency deviations may degrade load performance, damage equipment, resulting in overloading of transmission lines, which may interfere with system protection schemes, and, finally, may also result in an unstable condition of the power system. More so, Load Frequency Control ( LFC) plays a vital role in the modern power system as an auxiliary service to support power exchanges and, at the same time, to provide better conditions for the trading of electricity. Therefore, the tuning of the dynamic controller (i.e., net frequency and net power interchange errors) is a significant factor in achieving optimum LFC performance. Appropriate tuning of the controller parameters is required in order to achieve excellent control action. In view of this, this paper introduces the dynamic tuning of controller parameters in a two-area multi-source power system with an AC-DC parallel tie line for optimum load-frequency control performance. Matlab/Simulink software is used to realize the system simulation. System dynamic performance is observed for conventional PID tuning by the Ziegler Nichols method and the Kitamori method, fuzzy logic controllers, fuzzy-logic PID controllers, fuzzy PID controllers, and polar-Fuzzy controllers. Furthermore, the frequency and tie-line power response of the interconnected areas were compared based on the setting-time, peak-overshoot, and peak-undershoot. The simulation results show that the responses of the fuzzy-based controllers are faster than those of the classical controllers, resulting in minimized frequency and tie-line power deviations.

Published: November 2020

Bacterial Wilt disease is the most determinant factor as it results in a serious reduction in the quality and quantity of food produced by Enset crop. Therefore, early detection of Bacterial Wilt disease is important to diagnose and fight the disease. To this end, a deep learning approach that can detect the disease by using healthy and infected leave images of the crop is proposed. In particular, a convolutional neural network architecture is designed to classify the images collected from different farms as diseased or healthy. A total of 4896 images that were captured directly from the farm with the help of experts in the field of agriculture was used to train the proposed model. The proposed model was trained using these images and data augmentation techniques was applied to generate more images. Besides training the proposed model, a pre-trained model namely VGG16 is trained by using our dataset. The proposed model achieved a mean accuracy of 98.5% and the VGG16 pre-trained model achieved a mean accuracy of 96.6% by using a mini-batch size of 32 and a learning rate of 0.001. The preliminary results demonstrated that the effectiveness of the proposed approach under challenging conditions such as illumination, complex background, different resolutions, variable scale, rotation, and orientation of the real scene images.
Reliability and Availability of Multi-Channel IEC-61850 Substation Communication Networks for Mission-Critical Applications
Authors: Mathebula Vonani Clive , Saha Akshay Kumar
Published: November 2020

The introduction of IEC-61850 digital-based Substation Automation System (SAS) eases implementation of elaborate schemes; however, its reliability and availability continue to be investigated for executing mission-critical applications. Independent repairable multi-channel systems with voting capability such as ‘one-out-of-two’ tripping schemes are often used for critical safety-related functions because the individual scheme channels hardly ever fail simultaneously. The system configuration enables the scheme to self-reconfigure when a link failure occurs in one of the channels, as well as being repairable with no interruption to the overall mission. This paper reviews the reliability and availability of evaluation methods to highlight their advantages and disadvantages. Structure-function modelling, as well as Markov process incorporating Systems Thinking and Mathematical Expectation are used to model the reliability of IEC-61850 based SCN to demonstrate the shortcomings of combinatorial methods in the evaluation of mission-critical systems where diagnostic capabilities of the systems and imperfect repairs should be considered. It is evident from the results of the study that system diagnostic capability and repair efficiency cannot be ignored for mission-critical applications for the reason that the simplifying assumptions of combinatorial analysis methods greatly over-state the reliability and availability performance of the system as observed from the results.

Published: November 2020

The present study evaluates the influence of kitchen wastes on animal manures via anaerobic digestion for biogas production. The digestion was done using a digester with a capacity of 5L. The digester was loaded with the slurry of wastes prepared by mixing the wastes with water in ratio 1:1, and operated at mesophilic temperature of 37 ± 2°C for 30 days. The co-digestion of kitchen wastes with poultry droppings produced highest biogas yield (814.0 ml/kg VS fed) and the least (365.84 ml/kg VS fed) was from the co-digestion of kitchen wastes with the mixture of poultry droppings and cow dung. Composition analysis of the biogas showed the highest methane content (63.1%) from kitchen wastes and the lowest (56.2%) from co-digestion of kitchen wastes with poultry droppings. The pH range for optimum biogas production varied between 5.25 and 7.5. The study concluded that biogas yield from co-digestion of substrates, among other factors depends on the composition of participating substrates.

Dutch public health policy during the COVID-19 pandemic of the first half of 2020. Answers to questions on public health activities January–June 2020
Authors: Scheres Jacques , Curfs Leopold
Published: November 2020

The authorities’ first responses were the classification of COVID-19 as Group A-disease in the sense of the Law on Public Health, scaling up of regular crisis control structures, installation of an Outbreak Management Team OMT and a “National Operational Team-Corona”. COVID-surveillance is done by the RIVM (National Public Health Institute), and is based on data from Municipal Public Health Services (GGDs) supplemented with additional (inter)national sources. The OMT is the main advisory body regarding preventive measures and includes experts from relevant medical specialisms. Organisations of medical professionals gave separate advices. Sanctions to preventive measures can be fines and closure of accommodations. Initially, 80% of the population trusted the government’s messages and “intelligent lockdown” strategy. The Prime Minister’s addresses to the people were highly appreciated. However, at slow-down of the outbreak (May-June) society’s trust crumbled (“quarantine-fatigue”). The initial testing policy was very restricted and contrary to WHO’s adagium “Test, test, test!”. In June the Minister of Health announced that a capacity of 30.000 tests per day was achieved, to be scaled up to 70.000. The crises management’s primary concern was to increase the (ICU-)bed capacity and was achieved by transforming regular wards into COVID-care, setting-up external “Corona-wards” in hotels, and regional, interregional and crossborder spreading of COVID-patients. This focus on ICU-bed capacity was criticized, as half of the death cases and extreme equipment shortages occurred in other sectors (nursing homes, homecare, homes for the elderly, psychiatry, mental handicaps). Transformation of hospital wards also led to waiting lists for non-COVID care. End of June the government presented a step-by-step easing of the lockdown in which a fine-tuned epidemiological surveillance dashboard and the continuation of economical support for the economic sector are the backbones.
Ukrainian response to the COVID-19 pandemic: governmental interventions
Authors: Bakhnivskyi Valentyn , Ignashchuk Olena
Published: November 2020

In this article, the governmental response to the COVID-19 pandemic in Ukraine is described, starting from the first detected cases, up until the summer of 2020. Pandemic caught Ukraine’s health care system in the midst of a reform. At the time of COVID-19 outbreak, the first steps of primary health care reform were already being implemented while the reform at the secondary health care level were about to started. However, changes of the political environment (due to the elections 2019), two changes of the Minister of Health (since the beginning of the pandemic), the absence of the general plan of action followed by the inconsistent political decisions, and the uncertainty in financing mechanisms of the secondary health care facilities, made the COVID-19 pandemic challenging for Ukraine. The Ukrainian government had difficulties in devoting additional recourses to medical facilities to protect medical professionals and provide treatment for patients. Instead, as a main intervention to combat COVID-19, the government implemented lockdown from 12 of March to 12th of May that only postponed the raise of infections, preserved lives. While the pandemic still had a highly negative impact on the economy, initial analysis indicate that lockdown could be considered effective from the economics point of view.

Prestige brand strategy – the case of selected Asian technological companies Due to technological advance, in many sectors of the economy products have become very similar to each other. This is particularly true in relation to advanced technology products, which are often based on the same components and similar technology. This makes it difficult for an average consumer to make an assessment as to their quality and possible superiority. In this situation, brand becomes the most important differentiator and brand strategy has gained in critical importance in most technological companies. In order effectively to communicate with consumers, a brand has to focus on differentiating factors which are not common, and which are not being used by the other companies in an industry. Prestige is one of such original and nonobvious factors, defined in the present study as the ability of a brand to evoke feelings of individual uniqueness and social achievement. The aim of this article is to present Polish consumers’ prestige value perception of two Asian technological brands: Huawei and Samsung. These have been selected due to their leading position on the Polish mobile devices market. Analysis is based on empirical research made by means of CAWI interviews conducted with a sample of 1200 Poles. The research comprises two dimensions of prestige values: individual (uniqueness, personality demonstration, luxury) and social (proof of success, ability to impress others, status symbol). The results suggest that Samsung is perceived as a brand of higher prestige than Huawei in both dimensions: social and individual. Huawei is perceived as being fairly good in terms of proving success and of other social aspects, but it lacks the ability to evoke a feeling of individual uniqueness, personality expression, or luxury.
Taniec w kajdanach: chińska cenzura filmowa w latach 1949–1966
Authors: Gruszczyński Oskar
Published: November 2020

Dancing in chains: Chinese film censorship, 1949–1966 After the proclamation of the People’s Republic of China in 1949, and the subsequent nationalization of the domestic film industry three years later, the Chinese Communist Party gained unlimited control over the entire Chinese film world, while film itself became an instrument of state propaganda. In order to fulfill their role ‘in the service of workers, peasants, and soldiers’, filmmakers had to abide strictly by the requirements which the CPC had imposed upon them, and subject themselves to a rigorous film censorship system. Artistic independence and freedom were subject to the political needs of a one-party state and its ideology. The establishment of a full-fledged and extremely complex institutional censorship system in 1953 resulted in the emergence of two distinct phenomena: self-censorship and social censorship. Both of these made it possible for the CPC to gain full control not only over the film industry, but also, in certain aspects, over the minds of filmmakers as well as the audiences. This article aims at revealing the mechanisms of the Chinese censorship system in the period stretching from 1949 to 1966, and to elucidate the disastrous effects which these exceedingly rigorous control mechanisms brought upon the Chinese film industry in general in this turbulent era
How criminal courts blend punitive ends with immigration control aims: The decision-making process of the discretionary prosecution provision to authorise an administrative expulsion
Authors: Villagómez Moncayo Byron
Published: November 2020

The involvement of the criminal justice system in immigration control is nowadays a global phenomenon that has called the attention of academics and practitioners. The Spanish legal regime has not been immune to this occurrence, encompassing a series of situations in which criminal courts are required to make decisions that can have significant implications upon immigration law enforcement. One of the most noteworthy provisions in this regard is that by which criminal courts are allowed to exercise discretionary prosecution to authorise the administrative expulsion of a prosecuted foreigner (Art. 57.7 Aliens Act). Drawing on focused observation of a court setting and semi-structured interviews with judges, prosecutors, clerks, court personnel and defence attorneys, the main findings of this paper hover around the idea that expulsion is a court’s culturally constructed punishment, defined more by the meanings attributed to it by court actors than by its formal legal categorisation.

Bu araştırmanın amacı, öğretmenlerin cinsiyet, yaş, medeni durum, öğrenim durumu, mesleki kıdem ve okul kademesi değişkenlerine göre okullardaki dedikodu ve söylenti durumunu belirlemektir. Bu araştırma, kesitsel tarama modelindedir. Araştırmanın örneklemini, 2018-2019 eğitim öğretim yılında Ankara ilinde bulunan 20 resmi ilk ve ortaokulda görev yapan toplam 400 öğretmen oluşturmaktadır. Araştırmada; DiFonzo ve Bordia (2000) tarafından geliştirilen “Söylenti yönetimi ölçeği”, Eşkin (2010) tarafından geliştirilen “Hemşirelikte dedikodu ve söylentiye ilişkin ölçek” ile Leblebici, Yıldız ve Karasoy (2009)’ un “Örgütsel yaşamda dedikodunun araçsallığı ve algılanışı” adlı çalışmalarında geliştirdikleri ölçekler baz alınarak Özşarlak (2016) tarafından geliştirilen "Dedikodu ve söylenti ölçeği" kullanılmıştır. Araştırma sonucunda; öğretmenlerin, dedikodu ve söylenti durumuna ilişkin görüşlerinin katılıyorum düzeyinde olduğu görülmüştür. Bu durum, okullarda dedikodu ve söylenti mekanizmasının aktif ve yaygın bir biçimde işlediğini belirtebilir. Ayrıca öğretmenler tarafından okul içi dedikodu ve söylenti konularının varlığı, okul dışı dedikodu ve söylenti konularından daha fazla olarak görülmüştür. Tüm okul paydaşlarının sağlıklı etkileşim ve iletişimlerinin sosyal etkinliklerle sağlanması yoluyla okullarda dedikodu ve söylenti mekanizmasının olumlu etkilerinden faydalanabilecek okul atmosferleri oluşturulabilir.

Published: November 2020

An integrative taxonomic analysis combining molecular and morphological lines of evidence revealed a new cryptic species of the Microhyla achatina species group from the Langbian Plateau of southern Vietnam. The new species was previously confused with its recently described morphologically similar and sympatric sister species, M. pineticola. The new species can be distinguished from M. pineticola by the presence of a continuous dark stripe running from the posterior edge of its eye towards the groin (vs dark markings interrupted above the axilla), snout acuminate in lateral profile (vs rounded), belly colour pattern, and foot webbing. The new species is currently known only from Bidoup–Nui Ba National Park in Lam Dong Province, Langbian Plateau in southern Vietnam (at elevations of 1300–1600 m a.s.l). We suggest the new species to be considered as Near Threatened (NT) in the IUCN Red List. Our results emphasize that our understanding of the diversity of genus Microhyla is still far from complete, and provide further evidence for montane areas of southern Vietnam to be a centre of Microhyla species richness. Our study further underscores the urgent need for intensified integrative taxonomic research on Microhyla spp. in order to clarify the taxonomy of wide-ranging species complexes and to elaborate effective conservation measures.

Published: November 2020

Human–elephant conflict (HEC) is a major problem to Tissmaharama Divisional Secretariat (TDS) in Hambantota District, Sri Lanka. The current study was designed to identify and describe the patterns of HEC in TDS so that methods could be developed to minimise human and elephant deaths due to HEC. The data were collected through questionnaire surveys and internal data of the Department of Wildlife Conservation and the Meteorological Department of Sri Lanka. The results suggest that elephants feed on all cereals, fruits and vegetables available except citrus, pomegranate, sesame and bitter gourd. The majority of conflicts were caused by elephant groups of less than four individuals (94.3%). Elephant raids occurred mainly during the night and especially escalate towards January and September. There were no correlations between rainfall and crop damage. Both human and elephant males were more likely to die from HEC than human and elephant females.
Analisis Perilaku Konsumen, Produsen, dan Pasar dalam Islam pada Masyarakat
Authors: Aini Riani Nur
Published: November 2020

(Pasar)Islam adalah sistem hidup yang lengkap, universal dan dinamis dalam mengatur kehidupan manusia, termasuk kaidah Islam dalam mengatur tentang harga dan mekanisme pasar. Ketentuan harga itu diserahkan kepada mekanisme pasar yang alamiah. Sistem Islam menolak menetapkan harga oleh penguasa, karena Allah-lah yang menentukannya. Harga yang terbentuk harus sesuai dengan kekuatan penawaran (suplay) dan permintaan (demand) pasar. Olehnya itu harga barang tidak boleh ditetapkan oleh pemerintah, karena ketentuan harga tergantung pada hukum supply and demand. Sistem Islam sangat mendorong harga yang adil dengan mendorong persaingan pasar yang sempurna. Untuk memenuhi harga yang adil perlu adanya moralitas (fair play), kejujuran (honesty), keterbukaan (transparancy) dan keadilan (justice) serta menghindari segala macam bentuk spekulasi. Jika nilai-nilai ini ditegakkan, maka tidak ada alasan untuk menolak harga pasar. Sistem ekonomi Islam masih memberikan peluang pada kondisi tertentu untuk melalukan intervensi harga (price intervention) oleh pemerintah bila terjadi distorsi pasar, baik yang disebabkan oleh faktor alamiah maupun perilaku menyimpang dari pelaku pasar.

Published: November 2020

A study was conducted to describle the habitat preference of the Philippines tarsier in Loboc, Bohol. Description of habitat preference was based on species composition and density of the different layers of the stand, mean height, mean diameter and basal area including physical attributes such as aspect, slope and elevation. Three habitat variants of the Philippine tarsier were observed in Loboc, Bohol. The first variant was a relatively open thicket with many small-diameter trees and shrubs and dense undergrowths. The second variant was a thicket of tall grasses, many small diameter trees and dense undergrowths growing under a mahogany plantation. The third variant was a thicket of many small diamater trees and shrubs with less evident woody vines and dense undergrowths with limited exposure to direct sunlight and strong wind being situated along gullies. Preferred habitat of the Phlippine Tarsier are small diameter trees as roosting sites and dense undergrowth as a source of insects and small vertebrates which are preferred food of the animal. The presence of crevices, which are unique to the limestone environment, serve as "hiding places" to protect the animals from predators.

Authors:   College of Forestry and Natural Resources, Visayas State University, Visca, Baybay City, Leyte, Peque Dennis
Published: November 2020

This paper presents adaptive cluster sampling (ACS) as a method of assessing forest biodiversity. In this study, ACS was used to estimate the abundance of ecologically sparse population of Diospyros philippinensis (Desrousseaux) within the Visayas State University Forest Reserve. Its statistical efficiency were analyzed by comparing them to the conventional systematic sampling (Syst) estimator. Results indicated that adaptive cluster sampling (ACS) plots captured more trees into the sample compared to systematic sampling (Syst) plots. In addition, ACS estimates for mean and total numbers of individuals per ha was higher than systematic sampling estimates and in terms of variance ACS gave substantially lower variance than systematic sampling. However, the ratio of the adjusted SE of ACS to the adjusted SE of systematic sampling for each species and the combined data of the two species was generally lesser than 1 which means that ACS was not a better design than systematic sampling.

Published: November 2020

An optimization study of food products is important to be able to develop a nutritious and least costly product using the most efficient processing method. In this study, optimization of an oven-roasted peanut product was done. A two-factor factorial experiment with three levels of garlic solution (4,6, &8 w/w) and roasting time (40, 45 & 50 min) was conducted. Consumer acceptance test and specturm descriptive analysis were done using the 9-point Hedonic scale and 15-cm semi-structrued line, respectively. Roasting time had significant effects on all sensory parameters studied. Garlic level significantly affected fracturability. The optimum combination of 4-8% (w/w) garlic solution and below 47 min roasting time produced a product with acceptability scored of >6.50. Verification study showed the predictive ability of the model which implies that the processor has confidence to choose any combination from the above-mentioned values. Product quality specifications and intensity for color, garlic aroma, hardness, crunchiness, fracturability, toothpacking, saltiness, garlic taste, bitterness taste, peanutty taste and roastedness flavor were established.

Published: November 2020

Planktonic algae are free-floating phytoplankton that abound in aquatic and marine environments. They are the primary producers of aquatic ecosystems thus their role in the ecosystem cannot be overemphasized. This study was conducted in three sites of Pagbanganan River to determine the abundance and diversity of planktonic algae. A total of 39 genera under divisions Bacillariophyta, Chlorophyta, Cyanophyta and Charophyta were recorded. The most abuntat and dominant group were the diatoms (Divion Bacillariophyta). Navicula, Nitzschia, Synedra, Melosira and Coconies were the most abundant genera. The upstream, midstream and downstream sites were highly similar in phytoplankton composition and abundance. Phytoplankton were more abundant and dominant but less diverse during the months of April, May and June compared to July, August and September. Temperature, dissolved oxygen and nitrate levels were within safe limits but phosphate was in excess. Abundace was positively correlated with current velocity but negatively correlated with nitrate level.

The topic of Modernity is considered one of the prominent issues for societies that witness radical and comprehensive transformations in various educational, psychological, social, cultural and economic fields, which imposes its study by extrapolating the interactions that take place between these areas at the level of different sectors of society and tracking the effects that could lead to modernization A certain and its repercussions in the various parties and powers, so when analyzing the phenomenon of modernity, it is necessary to study a number of dynamic variables that affect the societal system and its educational, psychological, cultural, and social institutional framework, and the interconnected sites and related roles Mutual effect, modernity is a complex subject that should be addressed. The phenomenon of modernity is one of the recent phenomena that emerged after the Second World War, which makes it more difficult to study and analyze it, especially in developing countries that are undergoing a period of rapid social transformation, as it is noted that the institutions of society that have an impact on change respond very slowly and do not modify their practices only after they are subjected Strong pressures and influences, as a result of the intertwining factors and forces affecting the phenomenon of modernity. Key words: Arabic Literature, Modernity, The Arab World.

The facial image analysis for classifying human age has a vital role in Image processing, Pattern recognition, Computer vision, Cognitive science and Forensic science. The various computational and mathematical models, for classifying facial age includes Principal Component Analysis (PCA) and Wavelet Transforms and Local Binary Pattern (LBP). A more sophisticated method is introduced to improve the performance of the system by decomposing the face image using 2-level linear wavelet transforms and classifying the human age group using Artificial Neural Network. This approach needs normalizing the facial image at first and then extracting the face features using linear wavelet transforms. The distance of the features is measured using Euclidean distance and given as input to Adaptive Resonance Theory (ART). The network is trained with an own dataset consisting of 70 facial images of various age group. The goal of the proposed work is to classify the human age group into four categories as Child, Adolescence, Adult and Senior Adult.
A Study On Applications And Techniques Of Surface Re- Construction
Authors: Das Subhanga Kishore , Pattnaik Sabyasachi
Published: November 2020

This paper describes a general method for automatic reconstruction of accurate, concise, piecewise smooth surfaces from unorganized 3D points. Instances of surface reconstruction arise in numerous scientific and engineering applications, including reverseengineering, the automatic generation of CAD models from physical objects etc. Previous surface reconstruction methods have typically required additional knowledge, such as structure in the data, known surface genus, or orientation information. In contrast, the method outlined in this paper requires only the 3D coordinates of the data points. From the data, the method is able to automatically infer the topological type of the surface, its geometry, and the presence and location of features such as boundaries, creases, and corners. The surface reconstruction method has three major phases: Initial surface estimation, Mesh optimization, and piecewise smooth surface optimization. In this paper emphasis has been given on the initial surface estimation.

Adaptive filters, as part of digital signal systems, have been widely used, as well as in applications such as adaptive noise cancellation, adaptive beam forming, channel equalization, and system identification. However, its implementation takes a great deal and becomes a very important field in digital system world. When FPGA (Field Programmable Logic Array) grows in area and provides a lot of facilities to the designers, it becomes an important competitor in the signal processing market. In general FIR structure has been used more successfully than IIR structure in adaptive filters. However, when the adaptive FIR filter was made this required appropriate algorithm to update the filter’s coefficients. The algorithm used to update the filter coefficient is the Least Mean Square (LMS) algorithm which is known for its simplification, low computational complexity, and better performance in different running environments. When compared to other algorithms used for implementing adaptive filters the LMS algorithm is seen to perform very well in terms of the number of iterations required for convergence. This phenomenon can be achieved by a sufficient choice of bit length to represent the filter’s coefficients. This paper presents a lowcost and high performance programmable digital finite impulse response (FIR) filter. It follows the adaptive algorithm used for the development of the system. The architecture employs the computation sharing algorithm to reduce the computation complexity.

With modern video games surpassing every set of expectations in terms of graphics, game play, mechanics and hardware support, Artificial Intelligence in video games has also come a long way, from when it was first implemented in 1951. Although every set of games has an AI unique to itself, many of the algorithms are now developed such that they can be implemented in various games without any major changes in coding. But this could lead to the players exploiting AI in a single game to break the other games as well. Though this could be easily fixed by changing some minor fragments of algorithms, it would very well be an efficient way of developing complex AI for many games at once. This paper focuses on providing a cost-efficient way to implement AI algorithms that would benefit most of the upcoming and future games that will depend on AI to make themselves more dynamic to the players. This is done by taking the examples of various AI algorithms implemented in games like Pacman, Dota2, Tom Clancy's- The Division and many more.
