Published: September 2022

This paper is devoted to the development of a model of an autonomous electric power system to study random processes of voltage, current and power changes in emergency and dynamic operation modes. A diagram for calculating short-circuit currents has been presented, which was focused on a typical wide range of autonomous power plants with three diesel generator units. A model of an autonomous power plant has been developed, allowing to solve the assignments of determining short-circuit currents and starting currents of electric power machines. The equivalent network of the studied power system for transient calculations has been presented. Thus, the voltage waveforms have been obtained. A comparative assessment of theoretical calculation methods and simulation analysis demonstrated a high degree of accuracy of the simulation results. The use of approach suggested in the article and the developed model allows to increase the accuracy of conclusions when testing the abruptly variable processes and to make the most reasonable choice of measures to improve the quality of electricity and the reliability of electrical equipment. In particular, simulation analysis and obtaining transient curves for starting powerful consumers allow more accurately choose the type of circuit breakers used and the related configuration parameters.
Effectiveness of Low-Numerical Rank Approximation to Image Compression in Wavelet Domain
Authors: Reddy Arikera Padmanabha , Uddagatta Naveenakumara
Published: September 2022

In this paper, we report a modeling of approximation for images by finding numerical rank in the wavelet domain through singular value decomposition of approximation coefficients. Firstly, the digital image is transformed into the frequency domain. Then high-frequency sub-bands are quantized to zero. This is quite obvious in wavelet-based image compression. Simultaneously, the low-frequency sub-bands are compressing by using truncated singular value decomposition (TSVD) through a numerical rank. Finally, reconstruct the approximation matrix via inverse discrete wavelet transform with low computational intricacy. This mathematical model is more adequate for solving engineering problems arises in digital image processing such as the transmission of image (reducing the bandwidth size of a communication channel) and storage capacity (space saving). The simulation results on gray and color images show that there is a gain in: (i) the compression ratio with acceptable visual quality as per human vision system; (ii) balancing of performance measures over conventional SVD methods.

Authors: Harsito Catur , Permata Ariyo Nurachman Satiya , Arifin Zainal
Published: September 2022

Air conditioning systems have become very important at the end of this decade, due to global warming. Comfortable room conditions require a good air conditioning system. This paper aims to investigate the effect of the velocity inlet on central air conditioning. The boundary condition design was made using computer-aided design software. The temperature distribution was investigated numerically. The use of a central air conditioner with 12 inlet diffuser at a velocity of 0.7 m/s produces an even temperature distribution. The condition of the effective draft temperature produced is between -3 to 2 by 75% at an inlet velocity of 0.7 m/s. Meanwhile, at the inlet speed of more than 1m/s, the room temperature is met below 15℃. Thus, even temperature distribution and a suitable effective draft temperature can save energy consumption.
An Intelligent Feedforward Controller Utilizing a Modified Gorilla Troops Optimization for Nonlinear Systems
Authors: Mahmood Taha S. , Lutfy Omar F.
Published: September 2022

This paper presents an intelligent feedforward controller based on the feedback linearization approach to control nonlinear systems. In particular, the nonlinear autoregressive moving average (NARMA-L2) network is trained to reproduce the forward dynamics of the controlled system. Consequently, the trained NARMA-L2 network can be immediately integrated into the inverse feedforward control (IFC) structure. In order to improve the NARMA-L2 structure's ability to approximate nonlinear systems, the NARMA-L2 controller is comprised of two wavelet neural networks (WNNs). In addition, the RASP1 function was used as the mother wavelet function in the structure of the WNN rather than the more common Mexican Hat, Gaussian, and Morlet functions. To prevent the limitations of gradient descent (GD) methods, an artificial gorilla troops optimization (GTO) algorithm is used to determine the optimal settings for the NARMA-L2 inverse controller parameters. In particular, a modified version of the GTO algorithm, which is called the Modified GTO (MGTO) algorithm, is proposed in this work for training the NARMA-L2 inverse controller. This algorithm has demonstrated superior optimization outcomes in comparison to other methods. The effectiveness of the proposed control strategy is demonstrated using two nonlinear dynamical systems. Specifically, several evaluation tests are used to assess the effectiveness of the WNN-based NARMA-L2 in terms of control accuracy and robustness against external disturbances in each of the systems under consideration. These tests clearly demonstrated the effectiveness of the control system. Finally, a comparison study showed that the proposed WNN-based NARMA-L2 controller achieved better control results compared to the multilayer perceptron (MLP) and the radial basis function (RBF)-based NARMA-L2 controllers.

Sperm morphology evaluation is an important parameter for determining the quality
of semen and predicting fertility in rams. Different staining methods have been
developed to detect the morphological status of sperm, but there is no optimized
protocol, especially for animals yet. This study was designed to compare the results
using SpermBlue®, Diff-Quick, and Coomassie Blue stain in the morphological evaluation
of epididymal ram semen. In the study, samples collected from a Bafra ram (epididymal
sperm/ram) known to have a good breeding history were diluted with Trisbased diluent and
frozen. After thawing for each straw, three semen smears were made and stained with
SpermBlue®, Diff-Quick, and Coomassie Blue. All morphological parameters were evaluated
using a light microscope. 100 spermatozoa were examined randomly and classified
according to their characteristics for each slide. In identifying morphological
abnormalities, the staining protocols have compared amongst themselves, and no
significant difference between DiffQuick and SpermBlue® staining methods was observed.
However, significant differences were observed in midpiece abnormalities when SpermBlue®
and Coomassie-Blue staining methods were compared, while significant difference was
found in total abnormality in SpermBlue® and DiffQuick staining comparison (P <0.05).
As a result, all staining methods evaluated can be easily optimized for laboratory
conditions and used in the morphological analysis of ram semen.

This study evaluated the effect of oxygen supplementation on the hatchability of
fertile eggs of the Creole hen at 2718 meter above sea level. The experiment was carried
out with 1408 hatching eggs obtained at age different of the breeders (25, 30, 34 and 38
wks.). Eggs were assigned to four incubators with different periods of oxygen
supplementation: treatment without oxygen supplementation (SS) and oxygen
supplementations at week 1, week 3, and weeks 1 and 3. Body weight, hematocrit, and
hemoglobin were determined of embryos of 18 days incubation and newborn chicks. Hatching
percentage was calculated based on the number of fertile eggs. Early and late embryonic
mortality was determined. From the fertile eggs supplemented with oxygen during the
first and third weeks, a higher percentage of hatched chicks (82.60%) and lower
embryonic mortality were obtained. In the group SS, a low percentage of hatched chicks
(28.32%) and high embryonic mortality were found. Oxygen supplementation to fertile
creole hen eggs under hypobaric conditions in the Cajamarca valley did not increase
hemoglobin concentration or improve body weight of hatched chicken.
Role of the advisor to improve reproductive efficiency and cash flow in intensive
dairy cattle production systems

Published: September 2022

The objective of this work was to carry out a review of how reproductive
efficiency can be improved in dairies. Dairying in the world is demanding changes to
which we have to constantly adapt if we want to remain in the system. The constant
variation in the price of a liter of milk paid to the producer and in the cost of inputs
that are affected by the demand and the economic policies of each country, have
installed in the dairy producer the idea that milk production is a bad business due to
the low profitability of the sector with respect to other less demanding agricultural
activities such as agriculture. However, when analyzing production costs, there is a
very wide variation between farms depending on the efficiency and effectiveness with
which each establishment performs. The dairy chain has historically presented a dynamic
conditioned by demand (internal and external) that ends up setting prices for the
primary producer, thus conditioning the productive and technological path of the sector,
giving rise to recurring conflicts of interest between producers and industrialists. The
subsidy policies that are applied many times end up solving the specific situation of
the producer, complicating the situation of the markets of other countries. The
countries with the largest surpluses of milk, such as New Zealand, the United States of
America, Germany, France, Australia and Ireland, have to sell a large part of their
production to other markets, often complicating the producers of the importing
countries, for which they must become increasingly efficient in order to compete with
countries that subsidize primary production.

The Ferry Port of South Sumatra Province is located in Tanjung Api-Api, Banyuasin Regency. This port connects to the Port of Tanjung Kelian – Muntok, Province of the Bangka Belitung Islands. Problems that often occur in the management and operation of the Tanjung Api-Api ferry port are service performance problems that cause ineffective port management due to low service and the occurrence of queues of ships to lean on and carry out loading and unloading activities because they have to wait for ships that have not finished doing the activity on the pier. So that it causes complaints and dissatisfaction of service users with crossing transportation services. This paper is intended to analyze the service time of ships at the port by calculating the average time of raising and lowering passengers and vehicles as well as the average time of maneuvering ships docking and leaving the port pool, as well as adding the variables of opening and closing times for ramps and processing time for approval letters. The sail has not been added by previous researchers. Then the calculation results are compared with the service time that has been set at the Tanjung Api-Api ferry port. The results of the study the average service time of ships at the Tanjung Api-Api ferry port is 121.175 minutes/ship. The ship's service time exceeds the ship's service time that has been set at the port, which is 120 minutes/ship.

Abstrak

Pelabuhan Angkutan Penyeberangan Provinsi Sumatera Selatan terletak di Tanjung Api-Api Kabupaten Banyuasin. Pelabuhan ini menghubungkan ke Pelabuhan Tanjung Kelian - Muntok Provinsi Kepulauan Bangka Belitung. Permasalahan yang sering terjadi dalam pengelolaan dan penyelenggaraan di pelabuhan penyeberangan Tanjung Api-Api adalah masalah kinerja pelayanan yang menyebabkan pengelolaan pelabuhan yang tidak efektif dikarenakan rendahnya pelayanan dan terjadinya antrian kapal untuk bersandar dan melakukan kegiatan bongkar muat, karena harus menunggu kapal yang belum selesai melakukan aktivitas di dermaga. Sehingga menimbulkan keluhan dan ketidak puasan pengguna jasa terhadap pelayanan angkutan penyeberangan. Paper ini dimaksudkan untuk menganalisis waktu pelayanan kapal di pelabuhan dengan menghitung waktu rata-rata menaikkan dan menurunkan penumpang dan kendaraan serta waktu rata-rata manuver kapal merapat dan keluar dari kolam pelabuhan, serta menambahkan variabel waktu buka dan tutup pintu rampa serta waktu pengurusan surat persetujuan berlayar yang belum ditambahkan oleh peneliti sebelumnya. Kemudian hasil perhitungan dibandingkan dengan waktu pelayanan yang telah ditetapkan di pelabuhan penyeberangan Tanjung Api-Api. Hasil penelitian rata-rata waktu pelayanan kapal di pelabuhan penyeberangan Tanjung Api-Api sebesar 121,175 menit/ kapal. Waktu pelayanan kapal tersebut melebihi waktu pelayanan kapal yang telah ditetapkan di pelabuhan yaitu 120 menit/kapal.

Climate change is a global phenomenon that become a concern. Climate change affects the hydrological conditions of a watershed, including rainfall. Saguling Reservoir has a high erosion rate on the watershed. One factor that affects erosion based on USLE is the rain erosivity index which has a relation with rainfall amount. So the climate change effect of rainfall on erosivity factor in Saguling Reservoir watershed needs to be investigated because it will affect the erosion rate which is useful to determine the sedimentation rate of the reservoir. The purpose of this study was to analyze the effect of climate change on the erosivity index. Climate change (rainfall) was analyzed using GCM CanESM2 Model in the RCP scenario through a downscaling process. Downscaling has been done with SDSM. The rain erosivity index was analyzed using Lenvain’s formula. Downscaling with the SDSM method was able to give good results based on the coefficient of determination and it was found that there was a change of monthly rainfall in the short, medium, and long term periods, as well as an increase in annual rainfall up to 34.3%. The annual rainfall erosivity index changes along with changes in rainfall due to climate change and there is an increase of up to 44.1%.

ABSTRAK

Perubahan iklim merupakan fenomena global yang kini menjadi perhatian. Perubahan iklim mempengaruhi kondisi hidrologi suatu DTA (Daerah Tangkapan Air) antara lain terjadinya perubahan curah hujan. Waduk Saguling memiliki laju erosi tinggi pada DTA. Salah satu faktor yang mempengaruhi erosi berdasarkan Persamaan USLE adalah indeks erosivitas hujan yang terkait erat dengan besarnya curah hujan. Sehingga Pengaruh perubahan iklim terhadap faktor erosivitas hujan di DTA Waduk Saguling perlu diteliti karena akan mempengaruhi laju erosi yang berguna untuk menentukan laju sedimentasi waduk. Tujuan penelitian ini adalah menganalisis pengaruh perubahan iklim terhadap indeks erosivitas hujan. Analisis perubahan iklim (curah hujan) dilakukan dengan Model GCM CanESM2 skenario RCP melalui proses downscaling. Downscaling dilakukan dengan metode SDSM. Indeks erosivitas hujan dianalisis berdasarkan rumus Lenvain. Downscaling dengan metode SDSM mampu memberikan hasil yang baik berdasarkan koefisien determinasi dan didapatkan perubahan curah hujan bulanan pada periode jangka pendek, menengah dan panjang, serta untuk curah hujan tahunan terdapat peningkatan hingga 34,3%. Indeks erosivitas hujan tahunan di DTA Waduk Saguling mengalami perubahan seiring dengan berubahnya curah hujan akibat perubahan iklim dan terdapat peningkatan hingga 44,1%.

Unähnliche Ähnlichkeit : die Onto-Poetik des ukrainischen Philosophen Hryhorij Skovoroda (1722-1794)
Authors: von Erdmann Elisabeth
Published: September 2022

Im 18. Jahrhundert (von 1769 bis 1794) wanderte ein Philosoph durch die Landschaften um die Stadt Charkiv. Er wurde 1722 im Gouvernement Kiew des russischen Reiches geboren und schrieb und sprach über das richtige Sehen, das allein die Welt und den Menschen in Übereinstimmung mit Gott und in den Zustand des wahren Glücks (???????? ????i?) und der Glückseligkeit (??????????) zu bringen vermag. Der Hryhorij Skovoroda zählt zu den bedeutendsten Gestalten der ukrainischen und russischen Geistesgeschichte und ist der erste Philosoph in den Regionen des Russischen Reiches. Sein Denken ist lange Zeit widersprüchlich interpretiert und unterschiedlich verstanden worden. Diese 2005 als Buch und 2022 als Online-Version mit Überarbeitungen, Veränderungen und Anpassungen veröffentlichte Studie unternahm es, die Kohärenz von Skovorodas Philosophieren sichtbar zu machen. Alle Aspekte lassen sich in das antik-neoplatonisch-christliche Konzept der "einen Weisheit zu allen Zeiten" einordnen. Dieses Konzept wurde von den Kirchenvätern als Anverwandlung und Vereinnahmung hellenischer, jüdischer, orientalischer und lateinischer Denktraditionen für das Christentum entwickelt und praktiziert und in der Renaissance programmatisch als philosophia perennis etabliert und entfaltet. In den für Skovoroda wesentlichen Bereichen der Erkenntnistheorie, der Gotteslehre und Selbsterkenntnis, der Poetik und der Ethik kann innerhalb dieses historischen Horizonts eine kohärente Lektüre der Schriften Skovorodas erfolgen und belegt werden. Aus dieser Verortung Skovorodas in der kultur-, philosophie- und theologiegeschichtlichen Tradition Europas ergeben sich neue Aspekte für die ukrainische Kulturgeschichte und für die Zeit seit der Aufklärung in den Regionen des Russischen Reiches.

Aim: The rapid growth in the number of ground users over recent years has introduced the issues for a base station of providing more reliable connectivity and guaranteeing the reasonable quality of service (QoS). Thanks to the unique features of unmanned aerial vehicles (UAVs), such as flexibility in deployment, large coverage range and lower cost, UAVs can help the base station to provide wireless connectivity to the ground users, e.g., in rural and remote areas. As the energy limitation is the main concern for UAVs, the motivation is to provide uninterrupted connection to ground users in the next generation wireless networks using solar powered UAV-assisted air networks. Methods: The research uses global horizontal irradiance (GHI) data from the National Renewable Energy Laboratory, small cell power ratings for communication, and UAV parameters. In addition, the TensorFlow library and Python programming language were also used to develop machine learning models and simulate the UAV flying time. Results: In this paper, we develop a novel resource management system for UAVs, which consists of an energy harvesting deep learning model to predict the future power harvested from the solar panel and a consumption model which determines user arrival rate. With energy consumption and harvesting predictions, the resource management system adaptively switches the power consumed by a UAV for communication. In addition, based on the future energy availability and user's arrival rate, the resource management system communicates with other UAVs and enables energy coordinating scheduling among multiple UAVs to support user communications. The experiment results demonstrate that by using adaptive energy scheduling among UAVs, the flying time of the UAVs is improved by 40% during nighttime and by 37% when performing energy coordination among multiple UAVs. Conclusion: In this work, the UAV based communications have been researched. To understand more about UAVs and air segments, some literature review has been done based on previous works. Finally, alteration of the transmission power using several methodologies has been accomplished to increase the flying time of the UAV.

In this review paper, the occurrence in the plant kingdom and the biological activities associated to two specific phenyl-ethanoid glycosides i.e., leucosceptoside A and leucosceptoside B, were shown and discussed. This is the first work ever done on such subject. Analysis of the literature data clearly indicates that leucosceptoside A is much more common in plants and exerts many more biological activities than leucosceptoside B even if this also presents some important elements. All of this was widely discussed in this paper.
