Impact analysis on change in climatic conditions due to the development of highway roads and other infrastructures at Coimbatore - an evidence
Authors: Thenmozhi G , Cherian Mary , Nirmala M 
Published: October 2020

Abstract
Global warming, a major threat is mainly due to the increase in population. This leads to an increase in infrastructural facilities, and vehicles. The major reasons for the increase in temperature may be due to pollutant gases from Industries and Vehicles, other Infrastructural development, etc. Because of this, trees are being cut down which increases the temperature thereby reducing the rainfall. Also, rainfall decreases because of the destruction of trees leading to decreased groundwater levels. The proposed study primarily focuses on the change in climatic conditions such as temperature, relative humidity, and rainfall due to the development of infrastructures such as highway roads, bridges, etc. The above indicators were being addressed by many authors earlier, but there exists a gap in addressing the growth of infrastructure on the above-said factors. This proposed study presents a chance to address the gap that exists in the earlier literature based on the indicators specified above due to the infrastructural developments. Hence an Impact analysis is required to address the issues of infrastructure development especially for Coimbatore – Pollachi highway road. The detailed meteorological data of the past five years are taken for analysis and suggestions for Smart City projects, Policymaking decisions are addressed.

Abstract
The ordinary vehicle suspension system scatters the mechanical vibration vitality as a considerable amount of waste heat. In recent times the regenerative suspension systems have pulled in much consideration for the augmentation of vibration attenuating performance as well as the reduction of energy dissipation or harvesting the same. The main objective is to fabricate a prototype of Suspension Energy Regeneration System (S.E.R.S.) at a convenient cost for the automobile industry, further conduct the experiments, and analyse the power output. Also, to raise the fuel efficiency of the engine by decreasing the consumption of electrical energy produced by the I.C. engine by harvesting the same energy from S.E.R.S. Thus, reducing the fuel energy wastage and promote sustainable development. The main focus is to evaluate the possibility of using dynamo as a damping module in the Suspension system. The performance analysis was done to observe the differences between the operations of the conventional suspension system and S.E.R.S. After carrying out the necessary study, the simplified design of S.E.R.S. was made and fabricated which was cost-efficient as well as had enough power regeneration to support auxiliary electronic system in vehicles like audio system, headlights, etc.

Published: October 2020

Abstract
The effect of E-Waste particle on mechanical behavior of particulate reinforced epoxy resin composite has been studied. E-wastes are recycled by crushing and make it as filler particles. The E waste filler materials are added to thermosetting polymers of epoxy resins. The fabricated composites were composed of reinforcement as glass fiber (woven and chopped type), matrix materials as epoxy resin and E waste as filler materials. The samples are prepared along the basics of filler material of electronic waste added with liquid polymer as percentage ratios of 5%, 10%, 15% and 20 % of resin. The composite samples are fabricated by conventional method of hand layup process. The dispersion of electronic waste particles content efficiency was observed through the diagnosis of their microstructure through SEM images. Hence laminate composite with 15% filler content can be optimizes when compared to other three laminated composite samples.
Thermal performance of nanoparticle enhanced phase change material in a concentric cylindrical enclosure
Authors: Bala Akash M , Harish R , Shyam Kumar M.B. 
Published: October 2020

Abstract
This paper presents the flow and heat transfer characteristics of melting behavior of phase change material (PCM) in the presence of nanoparticles. The melting process occurs in a concentric cylindrical enclosure filled with PCM (ice) and aluminum oxide (Al2O3) nanoparticles. The inner and outer walls of the concentric cylinder are considered as hot and cold walls and maintained at a constant wall temperature. The problem is modeled as unsteady, two-dimensional turbulent multiphase flow using the Eulerian multiphase model and SST k-ω turbulence model. The numerical simulation is performed using Ansys Fluent 19.2. The primary and secondary phases are specified with thermo-physical properties of ice and aluminum oxide. The transient melting behavior of PCM is investigated for different nanoparticle volume concentrations by varying the temperature difference between the hot and cold walls of concentric enclosure. The results are analyzed by plotting the streamline, velocity and temperature contours. The results indicate that the dispersion of aluminum oxide nanoparticles into phase change material increases the heat transfer rate and decreases the melting temperature of PCM. The results also indicate that the melting rate and thermal performance are significantly enhanced with increase in volume concentrations and temperature difference.

Published: October 2020

Abstract
The melting and solidification process in enclosures filled with phase change materials has wide applications in metal casting, thermal energy storage, building insulation and battery thermal management. In the current study, the melting and heat transfer characteristics of Nano Enhanced Phase Change Material (NEPCM) are numerically investigated in a differentially heated square cavity. The NEPCM consists of ice as the phase change material (PCM) into which Single Walled Carbon Nano-tubes (SWCNT) particles of uniform size is dispersed. The left and right walls of the enclosed cavity are maintained at a constant wall temperature and considered as hot and cold walls and the remaining walls are treated as adiabatic and the simulation is performed using Ansys Fluent 19.2. The temperature difference between the hot and cold walls are varied and further investigations are performed by considering the effects of nanoparticle volume fraction on the melting behavior of NEPCM. The results are analyzed by plotting the stream function, melting interface temperature and velocity contours. The results indicate that the addition of SWCNT nanoparticles significantly influences the heat transfer characteristics and melting rate of phase change material. It is also found that the increase in nanoparticle volume fraction enhances the average melting and heat transfer rate of phase change material. The present results are validated and are in excellent agreement with the benchmark results available in literature.

Improved Dynamic Performance of Permanent Magnet Synchronous Motor using Maximum Torque Per Ampere with reduced number of switches
Authors: Sai Meghana G. , Krishna Kumari N. , Ravi Kumar D. 
Published: October 2020

Abstract
To attain the excellent dynamic performance of any drive the torque ripples must be as minimum as possible. Otherwise which leads to oscillations in a speed profile and hence results in poor performance of a drive. The proposal of this work is to reduce as minimum as possible in torque ripples of a Permanent Magnet Synchronous Motor (PMSM) by means of a Five Level Space Vector Modulation (SVM). The SVM is used to generate gate pulses for an Inverter. Maximum Torque per Ampere (MTPA) is considered which ensures minimum ohmic losses. To reduce the reduces number of switching states and hence switching losses and to generate gate pulses to a five level inverter, three level inverter using SVM is taken as a reference. To verify the designed system, a simulator is implemented in MATLAB software environment and a comparison of results with and without MTPA control is being shown. Results clearly show that torque ripple, THD of motor phase voltage and current are greatly reduced under MTPA control.

Published: October 2020

Abstract
In this study, industrial by-products like fly ash, Ground Granulated Blast Furnace Slag (GGBFS) and silica fume were used to develop the sustainable Self-Compacting Geopolymer Concrete (SCGC) under ambient curing. The combination of source materials is kept constant such as 50% fly ash, 30% Ground Granulated Blast Furnace Slag (GGBFS) and 20% silica fume, respectively. In the series of experiments, sodium silicate (Na2SiO3) solution of 1.75M is kept constant. The Solution/Binder (SB) ratio has been varied such as 0.65, 0.68 and 0.70. Rapid Chloride Permeability Test (RCPT), water absorption and Ultrasonic Pulse Velocity (UPV) of SCGC are measured at 28 days. The test results indicated that, the durability properties were inimically affected with increase in SB ratio and better properties observed with low content SB ratio. This because of increase in Silica (Si) content in the concrete undergoes slow polymerization process at ambient curing. The optimum mix with 0.65 SB ratio is identified with better results and considered for further studies.

Published: October 2020

AbstractIn India, the road transportation sector mostly depends only on petro-diesel. Progressively increasing prices at the same time fast diminishing rate plays a vital role in pursuit of alternative to petroleum diesel. Lots of research been carried out to explore economical as well as technical viable alternative source to petro-diesel. The sources broadly divided in to edible and non-edible category among which conversion of edible oil into biodiesel was not at all feasible in India. So most of the research been focused on nonedible oil sources for example Jatropha, Jojoba, Polanga, Karanja, Cottonseed, Neem, and Kusum. The oil per acre yield, growth rate and oil content percentage for these sources was not pretty good. In this scenario biodiesel from microalgae may be the better alternative source for petro-diesel for the developing country like India. This article is an attempt, to explain the biodiesel production method from algae along with its characterization. In addition, the comparative analysis of an important characteristic in tabular form between algae and other sources given for better understanding.

Published: October 2020

Abstract
The article is attempted to use the mathematical apparatus of fuzzy logic for processing the initial data of the model of an intellectual system for assessing the environmental safety of irrigated agricultural land and assessing the risks arising in the course of economic activity in the conditions of differentiated placement of crops. There is a proposed scheme for formalizing indicators set at a qualitative level which is based on membership functions. To determine the form of the membership function, limit, critical and high values of the level of environmental safety are identified. When describing model elements, we use a set of fuzzy situations that characterize the space of possible states of these elements, as well as a set of relationships between them. The assignment of communications that fuzzily is characterized the degree of influence between the typical states of pairs of elements allows the formation of production models in the form of a variety of fuzzy rules. The quantitative result of the interaction of elements is determined on the basis of fuzzy inference. The representation of the proposed model allows us to obtain an integrated assessment of the state of environmental safety of land and comparative characteristics of the magnitude of security threats are based on their automated assessment. The implementation of the proposed model allows us to obtain an integrated assessment of the state of environmental safety of land and comparative characteristics of the magnitude of security threats based on their automated assessment. Zoning environmental security threats are based on model. The developed model allows us to formulate recommendations on the set of necessary measures to prevent damage and minimize losses, as well as to evaluate the effectiveness of their execution in each specific case.

Published: October 2020

Abstract
Researh allowed to determine that value of water resources and competition for access to them would increase due to climate change. That is why role of fair and accurate water distribution to consumers both between different sectors of the economy and within them will increase (for example agricultural industry). Modern examples of water metering automation in irrigation systems demonstrate that partial automation is most often used, which uses SCADA technologies. It is still important to create a system for accounting for water consumption and distribution, consisting of several levels with the use of modern technological solutions, including SCADA technology, in the region or at the level of the water supply reclamation organization. No less important is the question of correlation of modern irrigation technology with the possibilities of irrigation systems.

The calculation is performed using a multivariate analysis of the obtained results. The need to search for the system optimal configuration with maximum capacity at minimum cost is determined by the major setback to use of renewable energy sources, such as the high cost of equipment. Initial data for math model as an example of the Hybrid Plant cost calculation was from nature conditions in Volgograd and cost equipment in the demonstration Zone of Volgograd State Agricultural University. The demo zone was created in the educational research and production center of University for conducting experiments on the self-generated power supply of the facility management.

Published: October 2020

Abstract
Energy dissipation of tall building structures suffering frequent violent shaking under strong excitation is a key research topic for the safety of such buildings. In this paper, a new-type tuned magnetic fluid damper with copper balls immersed is proposed to reduce the vibration under different excitation frequencies. First, the natural frequency of the damper was deduced by the Kinetic equations of magnetic fluid, and the sizes of the copper balls in the damper were determined by constructing the equivalent damping ratio model. Meanwhile, the viscosity changes of the magnetic fluid with different magnetic fields were obtained by establishing the finite element simulation of the magnetic field and carrying out the magnetic-viscous experiment about the magnetic fluid. The kinetic energy of magnetic fluid and copper balls were obtained by constructing dynamic finite element simulation model. The vibration experiment was carried out to verify the damping effect of the damper. Finally, the conversion of dissipated energy in the process of energy dissipation was analyzed by building fitting functions, and then analyzed in combination with the simulation results. The experimental results showed that the amplitude attenuation of horizontal vibration was obvious under the action of the damper when the excitation frequency was close to the natural frequency of the damper. In addition, most dissipated energy was converted into the kinetic energy of magnetic fluid and copper balls.
Empirical formulation for small circular electron fields

Published: October 2020

Abstract
An empirical model for small circular electron fields was developed. This can be of great help in the treatment planning process for small circular electron fields. A complete dosimetric analysis of the circular fields defined by electron cutouts diameters (2 cm–9 cm) was done for nominal electron energies ranging between 6 MeV and 20 MeV using a 3D water phantom and a pin-point ion chamber. Properties studied included depth dose, in-air inverse-square fall-off, and beam profiles. The Varian Clianc 2100 C accelerator was modelled, benchmarked and Monte Carlo simulations were performed using the EGSnrc/BEAMnrc code for the small circular cutouts. A simple exponential model was found to accurately predict the very important therapeutic depth (90% of Dmax) for the small circular field size within an accuracy of better than 2 mm in most cases. The model has only two parameters (d90 and ‘b’). Also, the penumbra widths (90% of the off-axis profiles) of these small circular electron fields were studied and least square fitted to a simple quadratic model. Full dosimetric profiles of these small circular electron fields were further studied using the benchmarked Monte Carlo simulations. This study presents a simple model to predict the very important therapeutic depth (90% of Dmax) and a recipe to develop such an electron treatment model for any linear accelerator system. Such predictions can be extremely valuable and time saving prior to treatment planning involving not only small circular shaped electron fields but also irregularly shaped electron fields.
PhotoniQLAB: a framework for simulating photonic quantum information processing experiments
Authors: Wu Zhihao , Wu Junjie , Huang Anqi 
Published: October 2020

Abstract
Simulators for photonic quantum information processing (PQIP) experiments are essentially different with currently available quantum-circuit simulators. In PQIP experiments, photons are usually encoded by multiple degrees of freedom, some of which are multi-level or even infinite-level. Moreover, the evolution of indistinguishable photons cannot be described elegantly by the model used in quantum-circuit simulators. A simulator focusing on PQIP experiments is urgently needed, as it plays an important role in PQIP experiments designing and verification. We developed PhotoniQLAB, an object-oriented framework designed for simulating PQIP experiments, which provides a virtual-lab user experience. The core simulation unit is a computer algebraic system based on the second quantization method. PhotoniQLAB only requires users to enter the structure information of a target PQIP experiment to conduct a simulation, as it can understand the topological structure by itself. The mathematical foundation and technical details of PhotoniQLAB are discussed in the paper. The performance of PhotoniQLAB, which is analyzed and used to simulate several experimental schemes in this paper, has been shown to be efficient enough for near-term PQIP experiments. PhotoniQLAB shows its flexibility and universality, through simulating more than 60 existing PQIP experiments in published papers. We believe that PhotoniQLAB will become a fundamental PQIP software infrastructure facilitating the analyses and designs of PQIP experiments.
Correlating AGP on a quantum computer
Authors: Khamoshi Armin , Evangelista Francesco A , Scuseria Gustavo E 
Published: October 2020

Abstract
For variational algorithms on the near term quantum computing hardware, it is highly desirable to use very accurate ansatze with low implementation cost. Recent studies have shown that the antisymmetrized geminal power (AGP) wavefunction can be an excellent starting point for ansatze describing systems with strong pairing correlations, as those occurring in superconductors. In this work, we show how AGP can be efficiently implemented on a quantum computer with circuit depth, number of CNOTs, and number of measurements being linear in system size. Using AGP as the initial reference, we propose and implement a unitary correlator on AGP and benchmark it on the ground state of the pairing Hamiltonian. The results show highly accurate ground state energies in all correlation regimes of this model Hamiltonian.

Published: October 2020

Abstract
This study aimed to investigate the influence of the CaO/SiO2 molar ratio on the physical, chemical and mechanical properties of alkali-activated fly ash with quicklime and assess the technical viability of the mortar with the highest compressive strength. Eight mortars were prepared, with a fixed sand to combined activator/precursor ratio of 3:1, varying the CaO/SiO2 ratio from 0.25 to 2.00 every 0.25. The doses that resulted in the highest and lowest compressive strength were CaO/SiO2 = 0.75 and 2.00, respectively, which reached 17.9 and 3.8 MPa at 28 days. Analytical techniques were performed to identify the products formed and the morphological differences in order to justify the variation in mechanical strength between mortars. EDS/SEM showed the formation of C-S-H, C-A-S-H and CH as well as other compounds in the mortars. XRD demonstrated greater CH formation in the mortars with the highest CaO/SiO2 molar ratio and CaCO3 in all the mortars, indicating that all the samples underwent carbonation. The TG/DTG results confirmed the presence of C-S-H, CH and CaCO3 phases in the mortars. Mercury intrusion porosimetry showed a significant difference in porosity between mortars with the highest (15.4%) and lowest (4.6%) compressive strength, confirming that this parameter also justifies mechanical strength differences.
