Authors: Kniazian Marianna , Khromchenko Olena 
Published: January 2020

The article is devoted to the problem of preparing of future ESP teachers in the context of higher education. Taking into account the necessity of solving the problem of acquiring not only purely theoretical and applied linguistic knowledge, but also knowledge from a certain professional area (for example, medicine, pharmacy, economics, law, engineering), the role of the formation of self-development competence as a means of expanding and deepening of vocational training gained at the university is presented. Self-development competence of the ESP teacher is the ability to evaluate one’s professional achievements, to choose the ways of optimizing personal level of intelligence aimed at self-improvement, to practically embody personality changes, control efficiency, adjust the conditions for self-change. The crucial components of this process are: self-analysis of knowledge, skills and know-hows, that can ensure full inclusion of the individual into professional and pedagogical activity at its highest innovative-creative level; designing ways of their development; selection and realization of corresponding receptions in all spheres of vital functions of the ESP teacher as a carrier and creator of humanistic values in society; self-control and self-correction. Self-development competence provides individuals with a promising opportunity to resolve problems characterized by increasing complexity, gradually expand their professionally important knowledge, master new creative opportunities.

Published: January 2020

Se analizan los factores de sostenibilidad de la acción colectiva en la gestión del agua de riego en los valles de Moche y Virú, situados en la costa de Perú. Utilizando un modelo de panel de efectos aleatorios, el análisis econométrico encontró que las variables relevantes para la sostenibilidad de la acción colectiva son diferentes en cada valle. El resultado económico se mide por la eficacia en el cobro de la tarifa de agua deriego, capacidad transferida por el Estado a las Juntas de Usuarios. Destaca, además, la importancia del proyecto de irrigación Chavimochic, que amplió la disponibilidad de agua en forma permanente, pero que enfrenta también los efectos del cambio climático...
Desde onde contemplar: sobre o primeiro livro de Franz Kafka
Authors: Brantes Simone 
Published: January 2020

Ao falar sobre Contemplação, o seu primeiro livro, Kafka diz haver nele uma “desordem sem salvação”, que “é preciso se aproximar muito” para ver aí “alguma coisa”. Esse artigo é resultado de uma tentativa de aproximação desse lugar ideal de contemplação a partir do qual não apenas podemos ver neste conto “alguma coisa”, mas a coisa que está em jogo em uma de suas últimas obras, o conto A construção. Em Contemplação, nos interessará o movimento dos personagens de dentro para fora e de fora para dentro e a fuga ao perigo de alienação que é representado por um outro com um poder aniquilador sempre articulados à busca da autonomia. “A coisa” que está em jogo em “A construção” e em Contemplação será a escrita na qual irão se cruzar, como estados inseparáveis, a autonomia e a alienação.

Background:Percutaneous coronary intervention is used in patients whose coronary arteries are narrowed and blood flow to the heart are obstructed. Antiplatelets has a major role in patients who have undergone PCI. Selection of antiplatelets is very important and study reveals about the factors associated with the selection of antiplatelet agents, thereby providing maximum therapeutic outcome. Objective: To determine the factors influencing the selection of antiplatelet agents in patients undergoing PCI.
Materials And Methods: A prospective observational study was conducted on antiplatelet agents by carefully analyzing the case records of patients who were selected as the study population. For collection of data, a data collection form was prepared. At the end of the study regression analysis was done to find out the factors influencing selection of antiplatelet agents.
Results: 350 patients were followed, 71.4% males and 28.6 females. Of the 250 male patients 67- SVD, 99- DVD and 84- TVD; whereas in females 29-SVD, 36- DVD and 35- TVD. There was a statistically significant correlation between hypertension (p=0.029), body weight (p=0.001), number of stent implanted (p=0.009) and diameter of stent (p=0.022) with drug. The prevalence of CAD was more in the age group 51-75 years and clopidogrel was the most preferred. Prasugrel was not used in patients greater than 75 years because of major bleeding. None of the patients with renal dysfunction were treated with ticagrelor. Conclusion: Hypertension, bodyweight, number of stent implanted, and diameter of stent were significantly associated with the selection of antiplatelet agents in patients undergoing PTCA.

Abstract
We present both necessary and sufficient conditions for a convex closed shape such that for every convex function the average integral over the shape does not exceed the average integral over its boundary.
It is proved that this inequality holds for n-dimensional parallelotopes, n-dimensional balls, and convex polytopes having the inscribed sphere (tangent to all its facets) with the centre in the centre of mass of its boundary.

Published: January 2020

Abstract
We describee some possible options for implementation of the Discrete multiwavelet transform (DMWT) of an image by using filter banks. DMWT can be implemented by two channel bank of vector filters which are made by cross-connected scalar filters. The properties of DGHM, CL, BiHermite and SA4 multiwavelets are here analyzed, and compression analysis for output normalization of DMWT is performed. A procedure is design of equivalent replacing of 2 channel multifilters bank by 4 channel bank of single scalar filters. Finally, we deal with a possible reduction and combinations of subbands and suggest their use.
Human action recognition using descriptor based on selective finite element analysis
Authors: Kapoor Rajiv , Mishra Om , Tripathi Madan Mohan 
Published: January 2020

Abstract
This paper proposes a novel local descriptor evaluated from the Finite Element Analysis for human action recognition. This local descriptor represents the distinctive human poses in the form of the stiffness matrix. This stiffness matrix gives the information of motion as well as shape change of the human body while performing an action. Initially, the human body is represented in the silhouette form. Most prominent points of the silhouette are then selected. This silhouette is discretized into several finite small triangle faces (elements) where the prominent points of the boundaries are the vertices of the triangles. The stiffness matrix of each triangle is then calculated. The feature vector representing the action video frame is constructed by combining all stiffness matrices of all possible triangles. These feature vectors are given to the Radial Basis Function-Support Vector Machine (RBF-SVM) classifier. The proposed method shows its superiority over other existing state-of-the-art methods on the challenging datasets Weizmann, KTH, Ballet, and IXMAS.

Published: January 2020

Abstract
Series linear voltage regulators are integrated circuits commonly used to make adjustable voltage sources. When used with potentiometers, these regulators are able to give adjustable voltage at the output. Memristor is a new nonlinear circuit element which came out in the last decade. It is able to provide electronically adjustable resistance. If a memristor is fed with a voltage over the threshold and it is not under saturation, its resistance also called memristance is dependent on the integration of its current, also called memristor charge. Memristor shows promise for different types and lots of digital and analog applications. In this paper, memristor-based series voltage regulator topologies are suggested and they are examined using parameters and simulations. Some design criteria have been given for the memristor-based series voltage regulators.

Published: January 2020

Abstract
A simplified sensorless speed control of permanent magnet synchronous motor (PMSM) using model reference adaptive system (MRAS) is presented. The MRAS is designed and incorporated in a complete closed loop PMSM control system fed by a three-phase inverter that utilizes a simplified hysteresis current control (HCC) to generate gating signals. Accurate rotor position, being essential in PMSM control, is estimated using MRAS rather encoders and resolvers which are explicit position sensors thereby eliminating the drawbacks of the traditional speed sensors in drive systems. The performance of this model is compared with an existing model that utilizes encoders and resolvers. Superior performance was obtained from this new model with MRAS. After initial starting transients, it is observed that the rotor speed for the model with MRAS settled to steady state at 0.10 seconds as against the model with speed sensor which attained steady state at 0.31 seconds. Torque response follows the same pattern to return to the load torque of 11Nm at steady state after starting. After speed reversal, the model with MRAS restored to steady state to track the negative speed command at 0.44 seconds. This is a superior performance compared to the model with speed sensor which settled at 0.60 seconds after speed reversal. The results have clearly shown the superiority of sensorless MRAS over traditional drive models with speed sensors. The software used for this research is MATLAB/Simulink 2017 model.

Published: January 2020

Abstract
This paper presents the design of a low-power and low-noise CMOS photo-transduction circuit. We propose to use the new technique of composite transistors for noise reduction of photoreceptor in the subthreshold by exploiting the small size effects of CMOS transistors. Several power and noise optimizations, design requirements, and performance limitations relating to the CMOS photoreceptor are presented. This new structure with composite transistors ensures low noise and low power consumption. The CMOS photoreceptor, implemented in a 130 nm standard CMOS technology with a 1.2 V supply voltage, achieves a noise floor of 2μV/⎷Hz within the frequency range from 1 Hz to 10 kHz. The current consumption of the CMOS photoreceptor is 541 nA. This paper shows the need for the design of phototransduction circuit at low voltage, low noise and how these constraints are reflected in the design of CMOS vision sensor.

Non-contact detection of impact damage in carbon fibre composites using a complementary split-ring resonator sensor
Authors: Li Zhen , Wang Tianqi , Haigh Arthur , Meng Zhaozong , Wang Ping 
Published: January 2020

Abstract
In this paper, a new non-contact method for detection of impact damage in carbon fibre-reinforced polymer composites with a complementary split-ring resonator sensor is proposed. The resonance frequency is evaluated as an indicator of the presence of damage. The resonator is made on a printed circuit board, and in the experimental setup it is positioned close to the area of interest. Electromagnetic models are built, and from the resonant responses the appropriate frequency range used for the test is determined. The active sensing element in the resonator is found from the analysis of the magnetic field distribution. The parametric study performed shows that a larger frequency change occurs for a wider impacted region, which is of great use for practical applications. The proposed method is validated by the experimental results, where a frequency shift of 65 MHz was observed for a 0.36 mm deep dent.

Abstract
Ferroresonance is a nonlinear phenomenon that damages the undesired, destructive system for energy transmission lines. The formation and development of this overvoltage ferroresonance phenomenon is an important research topic as a mysterious event in energy power systems. In this study, Seyit Omer-Iklar energy transmission line from Turkey’s electrical transmission networks was modelled using real parameters. Ferroresonance scenario was created on the model. The energy transmission system with the scenario is set to a simulation time of 4 seconds. The first two seconds are set to normal. By cutting off the transmission line in the 2nd sec., the system is provided with ferroresonance drift. According to the data obtained therefrom, spectrograms, instantaneous amplitude, instantaneous frequency and instantaneous phase were conducted. The analyses have made clear that the instantaneous frequency amplitude defined the system’s ferroresonance moment very well.

The paper deals with the problem to obtain robust PID controller design procedure to linear time invariant descriptor uncertain polytopic systems using descriptor system stability theory and H
2 criterion approach in the form of quadratic cost function. In the frame of Lyapunov function, H
2 quadratic cost function and Bellman-Lyapunov equation the obtained designed novel procedure guarantees the robust properties of closed-loop system with parameter dependent quadratic stability/quadratic stability. In the obtained design procedure, the designer could use controller with different structure like as P, PI, PID, PI-D. For PI-D controllers D-part feedback the designer could choose any available output/state derivative variables of real systems. The effectiveness of the obtained results is demonstrated on the randomly generated examples.

Authors: Warsiki Endang , Aprilliani Fenny , Iskandar Ade 
Published: January 2020

Abstract
Corrugated cardboard covered with ethylene absorbers is an innovation that can be used to extend the shelf life of mango fruit to slow the loss of fruit quality. Mango fruits ‘Gedong’ were placed in boxes having as the inner parts corrugated cardboard covered with ethylene absorbers. Three storage treatments – corrugated cardboard without ethylene absorber, with activated carbon or activated carbon + potassium permanganate – were used to find the best method to prevent quality deterioration of mango. The color change, mass loss, texture value, and total soluble solids content were evaluated after 10 days of storage. The initial results showed that the highest accumulation of ethylene production by fruit samples was 0.628 ppm·kg−1 on the fourth day after harvest, while the total ethylene production during 8 days of storage was 2.231 ppm·kg−1. The use of ethylene absorbers had significant effects on the quality parameters except for the color changes. Storage for 10 days in boxes lined with corrugated cardboard ethylene absorber in form of activated carbon + potassium permanganate resulted in the lowest mass loss (4.40 ± 2.6%), softness (0.2 ± 0.1 mm·g−1·s−1) and total soluble solids (14.7 ± 1.2 °Brix).

Authors: Moradinezhad Farid , Ghesmati Mehdi , Khayyat Mehdi 
Published: January 2020

Abstract
Jujube fruit quickly undergoes spoilage and normally has a short shelf life. Therefore, the effect of immersion treatment in different calcium salts on qualitative and biochemical characteristics of fresh jujube fruit was evaluated. Treatments included control (distilled water) and solutions of calcium chloride, calcium nitrate, and calcium sulfate at a concentration of 0.5 and 1%. Fruits were immersed in water or calcium salt solution for 5 min, air-dried and then cold stored at 4 °C for 50 days. The results showed that such treatment did not affect significantly the pulp color and the anthocyanin concentration in the fruit. However, the soluble solids in the treated fruits significantly decreased compared with the control. Interestingly, all levels of calcium salts, except 0.5% calcium nitrate, preserved the total antioxidant capacity in comparison with the control. Concentrations of 1% calcium nitrate, chloride, and sulfate significantly increased crispness compared with the control. The taste of fruit treated with calcium sulfate significantly deteriorated compared with the control and other treatments. In general, 1% calcium nitrate and 1% calcium chloride applied before storage preserved or strengthened the jujube fruit qualities after storage compared with control. It can be concluded that such treatment is recommended for practical application.

Published: January 2020

Abstract
In order to consider phosphorus (P) limitations in agriculture, research has been carried out on the methods that can improve plant growth and increase the efficiency of P use. A pot experiment was conducted to find the effects of magnetized Ca(H2PO4)2·H2O solutions as P source at concentrations 0, 5, 10, 20 and 40 mg·dm−3 and inoculation with arbuscular mycorrhizal fungi Diversispora versiformis on P use efficiency, growth and photosynthetic pigments in sweet basil. P solutions were treated with magnetic field of 110 mT at 3 dm3·min−1 volumetric flow rate. The results indicated that the growth of basil plant, the number of leaf, leaf area, harvest index and chlorophyll a and b contents significantly increased in the result of fertilization with magnetized P solutions and mycorrhizal inoculation as compared to the control. The application of magnetized P solution at 10 mg P·dm−3 and inoculation of mycorrhizal fungi increased P use efficiency by 18.9% and 23.5%, respectively. Findings of the experiment clearly showed that the use of magnetization of P fertilizer and mycorrhization potentially represent natural ways of promoting growth, P status and chlorophyll content in sweet basil.
