Effect of technological parameters of the process of pulsed magnetron sputtering on the structure and phase composition on TiN-based coatings
Authors: Soshina Tatyana O. , Mezentseva Daria S.
Published: April 2023

Subject of research: coatings based on TiN deposited by pulsed magnetron sputtering have been studied.

Purpose of research: is to establish the effect of technological parameters of the process of pulsed magnetron sputtering: the discharge current and the N2 content in the vacuum chamber on the structure and phase composition of coatings based on TiN.

Methods and objects of research: the phase composition and structural characteristics of the TiN-based coating were studied in the course of X-ray diffraction and X-ray phase analysis of coatings. The microstructure of the formed coatings based on TiN was studied using scanning electron microscopy. The object of the study were samples of VK6 hard alloy with TiN coatings.

Main results of research: it has been established that the magnitude of the discharge current has the greatest influence on the formed structure of the TiN coating. An increase in the content of N2 and the discharge current leads to a change in the phase composition and the formation of a single-phase coating based on the (111) c-TiN cubic phase with an increase in the degree of texture of the coating. The optimal values ​​of technological parameters are determined at which a coating based on the c-TiN phase is formed, with a minimum level of internal stresses, the smallest grain size, and a dense, columnar structure.

Authors: Antonov Alexander I. , Rudy Dmitry Yu. , Khatsevsky Konstantin V.
Published: April 2023

At present, semiconductor converters have found wide application in the electric power industry [6]. One of the most common semiconductor converters is a frequency converter, as it provides a three-phase voltage with adjustable frequency from a three-phase mains voltage. However, it, like other semiconductor converters, is the cause of the appearance of harmonics and, as a result, the non-sinusoidal shape of the voltage curve [1]. Harmonics are the cause of such negative effects in the electrical network as concomitant heating of the windings of motors, transformers, etc., false alarms in distribution networks, asymmetry in industrial networks with three-phase sources when harmonics occur in one phase, the occurrence of noise in communication networks, the influence on adjacent low-current and power cables due to the induced EMF, and also with the appearance of harmonics, there is a need to increase the cross section of neutral wires due to the summation of harmonics multiple of the 3rd in three-phase networks [3]. Therefore, the study of the harmonic components of the voltage is an urgent task.

Subject of research: processes occurring in electrical networks with a frequency converter.

Purpose of research: to identify the presence of harmonic voltage components in electrical networks with a frequency converter.

Object of research: a research stand that simulates the operation of electrical networks with a frequency converter.

Methods of research: in the process of performing research, scientific and technical generalization of literary sources on the initial prerequisites for research, methods of the theoretical foundations of electrical engineering and the theory of electrical networks, the method of analytical research, methods of system analysis were used. Experimental studies were carried out by a complex method using the Resurs-PKE device.

Results of research he study: based on the studies carried out, it was shown that the frequency converter is a source of harmonic voltage components, while harmonics appear only in certain sections of the electrical circuit.

Authors: Zhu Gina , Ifuku Kelli Ann , Kirkwood Kimberly S.
Published: April 2023

Robotic approaches have facilitated the minimally invasive completion of increasingly complex surgical procedures. In the management of the difficult gallbladder, we have found that the wristed instruments, three-dimensional camera, the ability to use indocyanine green (ICG) with integrated fluorescent imaging, and ease of intracorporeal suturing to be useful in tackling the challenges associated with complex benign gallbladder disease. We describe the rationale and technical lessons learned during four cases of complex cholecystectomies that highlight the management principles and technical advantages afforded by the use of the robotic-assisted laparoscopic (RAL) approach. The cases include a subtotal fundus-first reconstituting cholecystectomy, subtotal fenestrating cholecystectomy, a cholecystocolonic fistula managed by a RAL subtotal fenestrating cholecystectomy, and an iatrogenic cholecystoduodenal fistula managed by RAL cholecystectomy. In each case, the operation was performed safely without intraoperative injury or conversion to open, and three of the four patients were discharged from the recovery room. In our view, these favorable outcomes were greatly facilitated by the robotic platform. It is our intent to share adaptations and innovations that we found helpful to encourage other surgeons with sufficient robotic experience to tackle complex gallbladder cases minimally invasively.

Authors: Zhou Yuan , Sun Zhe , Chen Bo , Huang Guangpu , Wu Xiang , Wang Tian
Published: April 2023

To improve the rehabilitation training effect of hemiplegic patients, in this paper, a discrete adaptive fractional order fast terminal sliding mode control approach is proposed for the lower limb exoskeleton system to implement high-precision human gait tracking tasks. Firstly, a discrete dynamic model is established based on the Lagrange system discretization criterion for the lower limb exoskeleton robot. Then, in order to design a discrete adaptive fractional order fast terminal sliding mode controller, the Grünwald–Letnikov fractional order operator is introduced to combine with fast terminal attractor to construct a fractional order fast terminal sliding surface. An adaptive parameter adjustment strategy is proposed for the reaching law of sliding mode control, which drives the sliding mode to the stable region dynamically. Moreover, the stability of the control system is proved in the sense of Lyapunov, and the guidelines for selecting the control parameters are given. Finally, the simulations are tested on the MATLAB-Opensim co-simulation platform. Compared with the conventional discrete sliding mode control and discrete fast terminal sliding mode control, the results verify the superiority of the proposed method in improving lower limb rehabilitation training.

Published: April 2023

ABSTRACTBackground: Determining the Vertical Dimension of Occlusion (VDO) was one of the procedures required to create a complete denture. VDO was the height of the lower third of the face that connected the distance between the subnation point found in the craniofacial and the gnation point on the mandible. The methods in determining VDO were very diverse, but there were no methods that considered as highly accurate presently. Hence, several methods of determining VDO were needed to obtain more accurate results. The finger length anthropometry method was a method that has been widely used as an alternative method in determining VDO because it was considered accurate, not invasive, cheap, and easy to implement. Objective: This study aimed to determine the correlation between the vertical dimensions of occlusion and the anthropometric length of fingers. Material and Method: The study was conducted by using the literature review method with the narrative review procedure. Research using Google Scholar, Science Direct, PubMed, and Semantic Scholar. Results: The results of the study of 22 articles reviewed had a positive correlation between VDO and all lengths of the fingers of the hand. The finger that had the strongest correlation with VDO in males was the index finger (r=0.804) and in females was the little finger (r=0.937) Conclusion: All fingers could be used as an alternative method in determining the Vertical Dimension of Occlusion.Keywords: Anthropometry, Finger length, Vertical Dimension of Occlusion

Published: April 2023

This study analyzes the government's role in collecting zakat funds in Indonesia based on Yusuf Qaradawi’s thought in his Fiqh al-Zakah. The study uses descriptive qualitative method with a case study approach. Government policies in collecting zakat funds need to be revitalized because the results obtained are still far from the set targets. The government must issue new policies so that the efficient collection of zakat can help the country and achieve benefits of its people. To achieve this goal, Yusuf Qardhawi offers several policies for the government, evaluating the amendments to zakat management regulations. In the book of fiqh al-zakah, Yusuf Qardhawi emphasizes that the govern-ment not only focuses on voluntary zakat but also pays attention to paying zakat physically and men-tally. The government must collect zakat from material (al-a'yan) owned by Muslims. Furthermore, the government must also deduct or collect zakat directly from the savings of the Muslim community in banks if they have reached the nisab and haul. This is done to achieve the potential target of zakat in Indonesia. In addition, the government also helps people to abort their obligations as Muslims. With this policy, Yusuf Qardhawi believes that the collection of zakat can run well and efficiently so that it has a real impact on the nation in general and Muslims.

An Analysis of Islamic Business Ethics in E-Wallet in Indonesia with A Case Study of Go-Pay
Authors: Minarni  , Asnawi Nur
Published: April 2023

This article aims to examine the E-wallet business from the perspective of Islamic Business Ethics. The reality in E-wallet transactions still raises pros and cons in terms of its validity according to the Islamic framework. This study uses a qualitative descriptive method and a phenomenological approach. The tendency of people in the industrial era 4.0 to use digital-based application services requires proper literacy for short and long term goals. The results of this study indicate that various types of E-wallet applications, one of which is Go-Pay, allegedly still contain things that are contrary to Islamic Business Ethics. This can be seen, among other things, in the provision of special discounts or free shipping for Go-Pay application users, as well as the deposition of user balances in conventional banks (ribawi banks). Contemporary scholars who argue that this transaction is permissible argue because the transaction uses a wadi'ah contract and is in the framework of paying ujrah in advance. Whereas the scholars who forbid the transaction argue that the transaction contract is qardh (debt receivable) so that if it brings out benefits in it then it is included in usury. In implementing Islamic business ethics in e-wallet cases, e-wallet users must pay attention to the validity of the contract according to Islam and the purpose of the transaction according to maslahah. As for e-wallet suppliers, they must prioritize aspects of transaction legitimacy, product halalness, honesty, responsibility and trustworthiness.

Industrialization is expected to bring positive impacts for the indigenous people in the form of the emergence of social change. The occurred social change is expected to present sufficient room availability, especially on social income, employment opportunity, and economy. Industrialization consequences lead to spatial dispersion problems, which the policymakers do not expect. The impacts are the emergence of the new social class structure change, the high urbanization flow, life necessity fulfillment competition, and the emerging social gap. This study is expected to discover and develop a spatial dispersion model to focus on the three cities in the industrialization process in terms of income, economy, and employment opportunities. To see the compatibility among the three spatial dispersion indicators (income distribution, employment opportunity, and economy) compared to industrialization, the researchers applied Structural Equation Modeling (SEM) approach to test the hypotheses and analyze the empirical data retrieved through the covariance matrices. The research findings showed the correlation among the three variables by analyzing the retrieved CR values and the probabilities. It can be concluded that income distribution, employment opportunities, and the economy significantly influenced industrialization in Bunder Village, Pademawu Sub-district, Pamekasan Regency. Future research should cover other variables or areas to broaden the insight into how these variables impact industrialization.

Collatz conjecture states that an integer n reduces to 1 when certain simple operations are applied to it. Mathematically, the Collatz function is written as . f k n = 3 k n+C 2 z , where z, k, C ≥1.Suppose the integer n violates Collatz conjecture by reappearing, then the equation modifies to n= 3 k 2 z n+ C 2 z . The article takes an elementary approach to this problem by calculating the maximum value of C 2 Z . Correspondingly, an upper limit on the integer n is placed that re-appears in the sequence. The limit is found to be n<3.5. Next, it shown that the integer n repeats in the sequence if n<0. Finally, it is shown that no integer chain exists that does not lead to 1.

Precision Agriculture is the ability to handle variations in productivity within a field and maximize financial return, optimize resource utilization and minimize impact of the environment. It is also the process of automated data collection, cloud storage and utilization to build robust decision support system. In case of Ethiopia, due to poor communication infrastructure coverage and absence of the state-of-the-art technology in the agriculture sector, implementing precision farming system is a challenging tasks in the domain area. In this work, we proposed a fusion of multiple sensors using IOT and IIOT infrastructure to collect critical data from farming fields to develop precision farming facility for decision makers. The main purpose was to monitor weather variability, automate irrigation process, extract critical soil properties. In addition, we have used time series data collected from sensor devices to build forecasting model. Fusion of multiple IoT device provide a mechanism in the agriculture area to deal with real-time monitoring of crops. It is cost-effective technology and required low-energy with edge computing sensor device. We employed the Message Queuing Telemetry Transport (MQTT) protocol to connect the Industrial/Internet of Things (I/IoT) to the cloud server. The communication between system user and sensor device has been done via cloud using Node-RED platform, web android APIs. The cloud-based Eco-system allows us to aggregate, visualize, and analyze live streams output from each sensor in real-time manner. Finally, we have built time series forecasting model using records collected by each sensor device. Using the multi-variate time series data-set, we have obtained about 99 forecasting accuracy on some important variables. Finally, we have developed mobile and web-based application for the end-user to monitor the proposed system remotely.
