Review of responsibility studies in Russian and foreign psychology of the 21st century
Authors: Volkova Yelena V. , Bashkatov Sergey A. , Chernyshova Lyudmila V.
Published: December 2019

The article presents the results of an analysis of studies of the responsibility category, performed in the 21st century by Russian andforeign psychologists. To search for Russian works, we used the databases of the Electronic Library of the Russian State Library and the Russian Scientific Electronic Library eLIBRARY.ru To identify the works of foreign authors, we analysed 2910 journals from the Web of Science database (Social and Behavioural Sciences – Journal List). It was established that in Russian psychology, responsibility is understood as a form of self-regulation, realised in the consciousness of oneself as a subject of behaviour and its consequences. Russian researchers in the 21st century conduct clarifying studies of the formation and evolution of responsibility, studying the features of this mental phenomenon in representatives of various social groups and professions, and exploring the relationship between responsibility and success. In modern foreign psychology of the 21st century, responsibility has still been viewed from the angle of solving the practical problems of social psychology. We have revealed that most of the studies are clarifying in nature and are devoted to the characteristics of collective responsibility, morality and guilt. It seems important that both Russian and foreign researchers widely use the attributive approach.

Scaling protection and restoration of natural infrastructure to reduce flood impacts and enhance resilience
Authors: Cunniff Shannon
Published: December 2019

Restoring natural infrastructure offers much promise as a means to reduce both flood hazard and exposure to complement and supplement other flood damage reduction strategies. Interest increased in flood risk reduction methods using natural and naturebased features, in part, because of increased recognition that such could provide both flood risk reduction and other benefits, such as water quality uplift, community recreational space, and fish and wildlife habitat. Recent flood disasters and the rising costs of disaster response and recovery have triggered policy shifts toward economically efficient investments that enhance greater community resilience. While natural infrastructure is becoming more widely recognized as a tactic for building community and ecological resilience to erosion and flooding, it remains underutilized. Actions to aid consideration of natural infrastructure and scale up its use are presented.

A review of the current doctrines of regional Economics
Authors: Vertakova Yu. V.
Published: December 2019

Regional economics received an additional field of research by attempting to combine its provisions with the doctrines of economic growth. The causes and effects of spatial clustering for economic growth are examined in the works of Lichtenberg,Vernon, Hinitz,Marshall, etc. The hypothesis of this study is based on theory of the IDA and the theory of localization economics.

Aim. The presented study aims to review the current doctrines of regional economics.

Tasks. The author analyzes the classical and modern scientific doctrines in the field of regional economics.

Methods. This study uses general scientific methods of cognition, axiomatic, hypothetical, abstraction, and general logical methods to systematize the results of studies of the current doctrines of regional economics.

Results. The results of the study, which include the examination and generalization of the current doctrines of regional economics, become even more relevant and receive new incentives for development by combining with other economic theories in an attempt to cover the whole spectrum of problems of regional economic development, which is a direction for further research in this subject area. Regional economics gained momentum through interaction with international and interregional trade theories. The development of a new trade theory based on the Dixit–Stiglitz model inspired a new interest in trade at different development levels. These changes in the trade theory facilitate the creation of multiple spatial economic models in the form of a new economic geography.

Conclusions. The approach to the current doctrines of regional economics is realized through the international business theory. The structural component of regional economics in this field of research should be determined through the formation of territorial clusters. The second group of works conducts analysis using more complex economic models based on statistical methods. The corresponding research methods make it possible to identify clusters by measuring local effects.

Nowadays, there are various signal processing methods that have been studied by many researchers in order to detect faults in power lines. From previous literature, signal processing that works based on time frequency analysis has been proven to accurately detect faults at high speed. In this study, wavelet transform is adopted to analyse fault occurrences on power line of distribution network. Three types of faults due to lightning, switching and short circuit fault were analysed based on their voltage waveform profiles. ‘Daubechies’ 4 (db4) mother wavelet and four levels decomposition were implemented to extract the features. Approximation at level 4 (A4) and detail coefficient at level 1 to 4 (D1-D4) were extracted to evaluate the energy, skewness, and kurtosis. Based on the results, lightning showed the highest energy, skewness and kurtosis compared to the short circuit and switching voltage waveform. Therefore, these features can be utilized as the new parameters for fault detection in a power system network

The reliability of distribution network can be improved with the penetration of small scale distributed generation (DG) unit to the distribution grid. Nevertheless, the location and sizing of the DG in the distribution network have always become a topic of debate. This problem arises as different capacity of DG at various location can affect the performance of the entire system. The main objective of this study is to recommend a suitable size of DG to be placed at the most appropriate location for better voltage profile and minimum power loss. Therefore, this paper presents an analytical approach with a fixed DG step size of 500 kW up to 4500 kW DG to analyses the effect of a single P-type DG in IEEE 33 bus system with consideration of system power loss and voltage profile. Four scenarios have been selected for discussions where Scenario 1: 3500 kW DG placed at node 3; Scenario 2: 2500 kW DG placed at node 6; Scenario 3: 1000 kW DG placed at node 18 and Scenario 4: 3000 kW DG placed at node 7. Results show that all the four scenarios are able to reduce the power loss and improve the voltage profile however Scenario 4 has better performance where it complies with minimum voltage requirement and minimizing the system power loss.

National River Water Plants are located along upper Klang and Gombak river catchment to purify the polluted river using direct contact methods. As the current water quality situation in the study area is poor due to the contribution of anthropogenic activities on the water quality degradation in these urban rivers, the investigation was performed using the Water Quality Index. This paper gives the overall performance of RWTP using Water Quality Index (WQI) calculation methods. The WQI act as the basis of environment assessment towards to river water quality classification under Malaysia National Water Quality Standards. As an overall result, 57 percent from the total effluents achieve target Class II and above and another 43 percent achieve Class III and below regardless of two (2) RWTPs are under target from the average monitoring; RWTP Sg Gisir and RWTP Sg Sentul. However, the result for RWTP Sg Sentul is not yet conclusive since the monitoring duration is less than 2 years. Certainly, RWTP Sg Gisir needs to be taken into consideration for more frequent maintenance of the RWTP or upgrading of the RWTP oxidation tank as suggested in several MBBR/IFAS operation. As to improve the RWTP performance to score higher WQI, the introduction of recycling sludge in the biological tank so it will be a shorter reaction time. Additionally, the RWTP owner should implement a frequent maintenance work into RWTP component especially clarifier, sludge collector, biological oxidation tank and rubbish trap collector.

An emergency road signing system is an important device to prevent road disasters, especially during jeopardize conditions. In this project, it is focused on the shallow depth of water from 10cm to 30cm that can slow down the vehicles or even causes the collision. Arduino UNO microcontroller is utilized to detect the waterlogged and shows the of water depth on the road sign to allow the drivers to make a decision ahead for passing through the waterlogged. Furthermore, ZigBee wireless module is used to interface the sensor and display to increase the movability of the display from the waterlogged location. The system is powered up by the PV panel to support green technology and protect the environment as well. From results, it is found that placing the three signboards before the waterlogged location is more effective for drivers to respond.

Changing of magnetic fields can cause electrical currents, known as geomagnetic ally induced currents that caused by solar storm. This current can affect power system especially power transformer as it can generate quasi direct current through the neutral of the transformer. Previous studies have shown that the risk is not just limited to high and mid-latitude locations, but extends to power grids at lower geographic latitude as well. This paper presents the simulation of GICs using a single-phase saturable transformer under steady state and operation with GIC in MATLAB SIMULINK. The simulation results illustrate that when transformers are under influence of GIC, magnitude off lux and magnetizing current are increase with in time and distort the core of hysteresis curve. It indicates that GICs generated by solar storms can saturate the transformer, cause other effects such as transformer heating and creating large amount of harmonics. The findings have proven that GIC is a threat to the power transformer and can damage power system network.

With the high demand in electricity consumption nowadays, it is crucial for regulator and utilities to ensure sufficient energy supply to meet electricity demand. Electricity demand is influenced by several factors such as number of customers, customer behavior, working hours, weather condition and holidays. Integrating renewable energy technology as part of electricity generation for self consumption has indirectly provide an option to customer to reduce his electricity consumption from the grid and help to save his electricity bill. One of the simplest solutions to install renewable energy sources is by installing rooftop solar photovoltaic (PV). In this paper, the economic feasibility of installing solar PV is discussed based on commercial customer load profile. This paper also presents the suitable PV sizing based on the payback analysis based on customer load profile. A commercial customer in Petaling Jaya, Selangor is used as a case study for this analysis. This study indicates that customer will be able to reduce their electricity bill consumption with the integration of solar PV system on the rooftop of their building. Customer is able to save their monthly electricity up to 28% if a total solar PV capacity of 1256kW is installed. The payback from this study indicates the payback period is approximately around 9 years.

In this work a SPICE model was developed for metal-insulator-metal (MIM)-based memristors. The proposed model was achieved by combining the current conduction mechanisms with the dynamical state variable phenomenon. To account for ionic conduction in memristor, the Mott-Gurney law for ion hopping was incorporated in the state variable derivative. As compared to the experimental data, the proposed model is well matched with the measured data. The memristance and root mean square (RMS) error were calculated to be 120 Ω and 0.02 respectively. Simulating the proposed model at frequencies greater than unity formed a smaller hysteresis loop area.

Motion detectors are sensors that record movement in a certain area. This study proposes the evaluation of three motion detectors, using the Arduino microcontroller to execute orders to the sensors infrared, PIR (passive infrared sensor) and ultrasonic, to determine the obstacle detection behavior against different objects. According to the tests carried out and the theory presented for each sensor, we have found that the most efficient sensor for object detection is the PIR, due to its scope and viewing angle, which represents being feasible and more reliable to implement; for example, in security systems.
