Morality over Pleasure Principle: A Psychological Study of Biblical Character Samson and Senior Pazhuvettaraiyar in Kalki's Ponniyin Selvan
Authors: Sofiya W.M. Roselin , Dunston Dr. G. M. Joseph 
Published: November 2022

In this article, the researcher endeavours to compare and critique the characters of Biblical Character Samson and Senior Pazhuvettaraiyar from Kalki’s Ponniyin Selvan in the light of Sigmund Freud’s three components of mind- Id, Ego and Super-ego. By applying the psychoanalytic theory, the present study brings out the internal conflicts in the select characters. This article primarily focuses on a) witnessing both of the character’s behavioural responses, such as changes in attitudes, actions in life events, pursuit of love, which has been taken for psychological investigation, b) analysing the morality over pleasure principle, which makes the characters significant in the readers' minds. The present study has hypothesized how the instinctual drive of 'Id' becomes the major cause of Senior’s suicide in an open court. It also investigated how the life and death drives of the Id function in Samson’s suicide are discussed. The character investigation in the above backdrop will bring a different aspect to appreciate Kalki's masterpiece by attaining ‘Catharsis’ in readers' minds. The scope of this study is to understand the interchanging of the masks of each character, representative of the interactions of the different personality levels, that provides the reader with insight into who each character truly is. This psychological approach will help the reader identify each individual's personality by their actions.

Published: November 2022

This work was carried out to improve the performance of an ozonation system used for wastewater treatment in a pharmaceutical industry. In order to improve the mineralization of organic matter, ferrous sulfate was applied as a catalyst to the reaction system. After this, the pH of the water was adjusted to 8.5–10, so that the process is carried out under alkaline conditions. Finally, O3 was injected through a Venturi tube in order to improve the mass exchange between gas and water. Preliminary operating data indicate that the treatment system achieves chemical oxygen demand (COD) removals of less than 10%. The tests were conducted at full scale and the water quality variables were analyzed at different reaction times. It was determined that for an ozone dose equal to 10 g/h and 10 mg/L Fe2+ and an initial water pH equal to 9, 4.5 hours were required to achieve a reduction of 30.73% COD and 36.85% total organic carbon (TOC). The results obtained with an initial pH higher than 9.5 indicate that the effectiveness of the process is reduced, a fact that may be caused by the rapid formation of insoluble Fe(OH)3, which decreases the availability of the catalyst for the formation of OH* radicals in the water.

Published: November 2022

Abstract
This paper presents a new hybrid meta-heuristic algorithm based on the Phasor Particle Swarm Optimization (PPSO) and Gravitational Search Algorithm (GSA) for optimal allocation of distributed generation (DG) in distribution systems with non-linear loads. Performance of the algorithm is evaluated on the IEEE 69-bus system with the aim of reducing power losses, as well as improving voltage profile and power quality. Results, obtained using the proposed algorithm, are compared with those obtained using the original PSO, PPSO, GSA and PSOGSA algorithms. It is found that the proposed algorithm has better performance in terms of convergence speed and finding the best solutions.

Published: November 2022

Abstract
The paper presents modelling and control of very common actuator, DC motor. The control of the DC motor was implemented with the Model predictive control (MPC) controller based on Legendre orthonormal functions. As PID (Proportional-Integral-Derivative) controller is simple and effective controller, mainly used in industrial applications, above mentioned MPC controller’s performance was compared to the PID controller performance. A criterion used is the fastest response with the maximum of 2% overshoots with step input and step disturbance treated.
A Comprehensive Study of Shape Orientation Methods for Extraction of Phase-Preserving Fourier Descriptors
Authors: Sokić Emir , Salihbegović Almir , Konjicija Samim 
Published: November 2022

AbstractThe magnitude-based Fourier descriptors (FD) are frequently used in shape-based image retrieval, due to their efficiency and effectiveness. Unlike the phase-preserving Fourier descriptors, the magnitude-based Fourier descriptors are inherently invariant under rotation and starting point change, but they discard all valuable information contained in the phase of the Fourier coefficients (FCs). In order to preserve the coefficients’ phase, the orientation and starting point of the shape must be determined. In this paper, we conducted a comprehensive evaluation of different state-of-the-art methods for determining nominal shape orientation, which can be used to extract phase-preserving Fourier descriptors: the point of maximal radius, the axis of least inertia (moments), the phase of the first harmonic, the cross-correlation, the Procrustes distance and the pseudomirror points. The methods were compared in terms of sensitivity to non-rigid transformations, retrieval performance, computational complexity and computational time. The experimental results give insight into the pros and cons of all analyzed methods.

Published: November 2022

Abstract
Recycling demolition waste materials as construction materials offers environmental as well as economic benefits by protecting virgin materials and reducing overall costs of project. This paper presents an experimental investigation on flexural behavior of reinforced concrete beams made with coarse aggregate fully 100 % or partially 50 % replaced by crushed concrete or crushed bricks as waste materials in full or half depth of beams. Nine beams are tested over a simply supported span, one with full natural aggregate as reference and the others with waste aggregate in different ratios and depths (four with crushed concrete and four with crushed bricks). Results show that the structural behavior of beams with waste aggregates is similar to the reference beam with strength reduction of 3 – 20 %. Crushed concrete beams show higher strength and stiffer behavior (in general) than crushed bricks. Also, increasing replacement ratio from 50 % to 100 % or replacement depth from half to full reduced strength by about 10 % only which encourage utilizing maximum quantity of waste construction materials in concrete structures.
Experimental Investigation on Mechanical Properties of Lightweight Aggregate Concrete

Published: November 2022

AbstractThis present research work mainly focusses on an investigation of the workability and strength properties of lightweight aggregates, particularly Palm oil shell and pumice aggregate, used in the production of concrete with (PA) and (POS), which were substituted for conventional Hard Broken Stone (HBG) coarse aggregate. Through the use of lightweight aggregate (POS and PA) in place of some of the coarse aggregate, the properties of a lightweight concrete M30 have been concentrated in this experimental study. The lab tests that were conducted include the compaction factor test, Schmidt Hammer test (rebound hammer test), and compressive strength. A total of 108 numbers of cube specimen were employed of size 2400 kg/m3. As part of a parametric study, the total number of cube specimens was divided into two groups according to various percentages: palm oil shell and pumice aggregate. In order to cast the cube specimens, dry weight of coarse aggregate was substituted for 0, 10 %, 20 %, 30 %, 40 %, and 50 % of POS and PA lightweight aggregate, respectively. A total of 9 cube specimens were cast and tested for 3, 7, and 28 days after successful curing in order to obtain accurate results. Average values were obtained from the test program and are shown in the corresponding Tables. Slump, compaction factor, rebound hammer compressive strength, and compressive strength values with different amounts of light aggregate were used to assess how well concrete performed when coarse aggregate was partially replaced with light aggregate. The test findings revealed that when the amount of conventional aggregates substituted by POS and PA increased, the slump test, compaction factor test, and strength of the lightweight aggregate concrete (LWAC) rapidly diminished. With an increase in the amount of aggregates replaced by POS and PA, the LWAC’s absorption has gradually increased as water. It is stated at the outset that the POS has shown to perform better than the PA when construction is done using structural lightweight concrete.
