Published: August 2021

Abstract
To analyse the water demand for rural regions is very important to distribute the public water demand and agricultural water demand. In this contest, rural areas under three reservoir command areas namely Konam, Raiwada and Thandava Reservoir command areas located in Visakhapatnam district are selected. Different methods are used for population forecasting and the results are compared with the available actual population in 2011. Decreasing rate method gives satisfactory results and this method is used to determine the present population in the selected rural regions. Total demand for all three regions is obtained and agricultural demand is about 94 to 96%, domestic water demand is about 2.5 to 3.5 %, water losses is about 1 to 1.5 %, fire and public use demand is around 0.5 %, and industrial and commercial demand is less than 0.5% of the total water demand. Per capita total water demand various from 1415 to 1817 cubic meters for selected regions.

Published: August 2021

Abstract
A competent alternative approach to the conventional modelling techniques is artificial intelligence (AI). AI is about the computer science division that creates human intelligence machines and applications. AI-based solutions are great substitute where research is not feasible to evaluate engineering design parameters and therefore contribute to substantial human-time and effort savings in experiments. AI can also speed up the decision-making process, minimize errors and improve performance. AI can also make the decision-making process faster, reduce error rates and improve computing efficiency. Reinforced pile embankment is a useful technique used in soft soil construction, because of its advantages in reducing settlement, building time, and economic efficiency. The response of deep bottoms subjected to a uniform static surcharge was considered in most of the existing research. Very few researchers have studied the cyclical load effect or the effect of variation in depth. An experimental analysis was carried out on the impact of cyclical loading at a specific area of unreinforced and reinforced embankment of differing heights. During the initial stages of cyclical loading, soil arching, regardless of the height of the embankment, was adversely affected. However, the arching of the soil started to improve somewhat by increasing the number of cycles. The magnitude of the loads transferred to piles was increased by the reinforcement layers. But for a thinner embankment, the improvement was more obvious. The main purpose of this report is to identify the AI techniques that can be used to analyze the behaviors of pile foundation undergoing cyclic loading by making models which will help in testing different kinds of failure patterns and the solutions with which these problems can be mitigated.

Abstract
Concrete is the most preferable and widely used construction material in the infrastructure development. For concreting and curing huge amount of potable water is required and it is difficult to get this at all places and all times. One of the best alternative solution for this problem is using the self curing concrete. In this experimental study the mechanical properties of hardened concrete by partial replacement of cement by 0, 40 an 60% of GGBS for M20 and M35 grades of concrete using 0.5 and 1 percent of Poly ethylene glycol as self curing agent. Cubes and cylinders are cast and tested at age of 7 and 28 days, for compressive strength and split tensile strength. The results of conventional concrete are compared with the results of concrete with GGBS and Polyethylene glycol 400 for both grades of concrete. The test results have revealed that addition of 0.5% of self curing agent show higher strengths for 60% replacement of cement with GGBS while 1.0% of self curing agent showed good results for 40% replacement for M20 grade of concrete.

Authors: Li Chao , Yang Xun , Peng Kewen 
Published: August 2021

Abstract
Trombe wall system is a typical passive building technology that can use stack effect to induce indoor ventilation, adjust indoor thermal environment and reduce building energy consumption. Present researches mainly aimed at its application in winter heating, and seldom involve summer ventilation and cooling. In this research, two comparative test rooms were established, one with the Trombe wall system installed in the south facade, and the other used as a contrast. By comparing the response characteristics of the two rooms to the outdoor climate, the performance of the Trombe wall system was studied in summer climate conditions in hot summer and warm winter zone of China. During the experiment, the indoor and outdoor environmental parameters and the performance parameters of the Trombe wall system were tested. The result illustrated that the Trombe wall system can make full use of the absorbed solar radiation heat to induce indoor ventilation, with a maximum circulating air flow rate of 140m3 / h (32.7h−1). And it can effectively reduce the indoor temperature by up to 4.1 °C during the daytime by compared with the reference room. The heat entering the room through the Trombe wall system was more than that of that through the south façade of the reference room. However, the excess heat can be ventilated to the outdoor through the air vents of the Trombe wall system by the effect of high indoor ventilation times. This prevents the air temperature in the room from rising.

Abstract
Natural fiber polymer composites are generally used in the furniture, home appliances, construction works. Present work is based on the simulation of the Graphite Fiber Reinforced Polymer (GrFRP) composite laminates through numerical model. In simulation we get maximum 7% error with the available experimental results. Analyzed a beam which is made from natural fiber reinforced polymer composites. It consists of eight stacks of natural fiber lamina, a central hole, both the ends supported as fixed and loaded by a uniformly distributed load (UDL). A numerical tool have been developed to analyze the Jute Fiber Reinforced Polymer (JFRP) composites. In this analysis, four different sequencing pattern of lamina has been used. The numerical failure index and failure strength for the different tacking sequences of lamina is determined. The maximum failure strength for the (60 °/-60 °/60 °/-60 °)s laminate is 22.51MPa. We found that in the simulation the results of the model are very close to experimental results. Its method of analysis is more convenient and economical over the experimental work. Therefore, the method was found very suitable for modelling and analysis in future.

Published: August 2021

Abstract
This research describes about the thermal analysis of fins by FEA method. Fins are extended surfaces which help to increase the heat transfer rate[1]. In this research we observe that when heat is produced in IC engine when fuel is burned, will have to be at higher level so that thermal efficiency increases, but to fend off from damages like thermal damage, useless or excess heat have to be removed from the engine. In air cooled engine, fins are placed at upper layer or on boundary of engine cylinder to increase heat transfer rate, because of this analysis of fins is very important and help to enhance the performance of engine and also increase the life span of the engine parts. The main aim of this research is to analyse the thermal properties of fins by varying certain conditions i.e. doing some modifications in conventional model, in our research work we have done two modifications in the fins geometry. In modified model-1 we have increased the number of fins, to achieve this we decreased the gap between the fins of conventional model. And in modified model-2 we have done circular perforation of 4mm diameter on the faces of all the fins of the conventional model. The cylinder head with fins are modelled on Soildworks software 2019 version and all model’s analysis is performed on Ansys software. We have used Steady State Thermal of Ansys mechanical to perform our analysis. And as per the analysis the results showed that modified model-1 has the maximum heat transfer rate as compared to other models.

Published: August 2021

AbstractIn load bearing implants metallic biomaterials have the first preference in orthopedic surgery because of their good mechanical properties which satisfied the prerequisite of human cortical bone. However metallic implants have limitations of poor wear resistance and release of metal ions resulting in to implant failure. To overcome these limitations hydroxyapatite based coatings on metal substrate can be used. The application of hydroxyapatite coating with the second reinforcement improve the fatigue strength of composite coatings. In this paper, commonly used metallic biomaterials for application of hydroxyapatite based composite coatings are discussed. Plasma spray coating technique with variable process parameters has been considered for this review. Presently plasma spray technique is commonly used for application of HA coatings in medical industry.
Geometrical improvement in machined micro-hole using adaptive tool feed system in electrochemical based discharge machining
Authors: Rajput Viveksheel , Mudimallana Goud , Suri Narendra Mohan 
Published: August 2021

Abstract
Electrochemical based discharge machining (ECDM) removes the material by utilizing the thermal heating of the sparks followed by the chemical action. The tool feed method in ECDM controls the geometrical accuracies since gravity assisted and constant tool feed results in tool contacts that further deteriorates the micro-hole geometry. Moreover, high number of thermal cracks are produced with these tool feed methods.
The present study investigates the adaptive tool feed system that withdraws the tool in upward direction when its contact with the work material is observed. Adaptive tool feed results in minimum tool contact and enhances the geometrical accuracies of the micro-holes. Hole circularity error (HCE) is taken as the response parameters for investigating the geometrical accuracies. The microscopy images reported a significant improvement in the geometry of the micro-holes machined with adaptive tool feed when compared to other tool feed methods. An improvement of 43.7% in HCE is acquired with the application of adaptive tool feed at 40 V. Moreover, the effect of input parameters on geometrical characteristics in terms of HCE is also discussed. The present study successfully reports the geometrical improvement of micro-holes in ECDM.
Effect of swirl flow on characteristics of the annular diffuser
Authors: Singh Hardial , Arora B.B. 
Published: August 2021

Abstract
The current work deals with the axial flow annular diffuser’s performance characteristics with divergent casing angle 9° with an area ratio of 3. We performed the numerical simulation to examine the inlet swirl’s effect on the annular diffusers. The velocity profiles were measured along the span of diffusers at a number of locations. Analysis of the results shows that the inlet swirl improves the stability at outlet flow, gains the recovery of pressure, and delays the flow separation on the casing. It is found that static pressure recovery increases by 5% with swirl flow. The results prove that the best performance is observed in the unequal hub and diverging casing diffuser with an equivalent cone angle of 15° and the inlet swirl angle of 12°.

Abstract

Objectives
This study presents the clinical assessment of the Onclarity HPV Assay (Becton Dickinson) on the novel COR high-throughput instrument (Becton Dickinson) using the international guidelines in a routine setting.

Methods
Screening samples collected in BD SurePath from women aged 30 years and older were used in this validation. Noninferiority of the Onclarity HPV Assay on the COR instrument (Onclarity-COR) was assessed with the comparator assay glycoprotein 5–positive (GP5+)/6+ enzyme immunoassay (GP-EIA) for clinical sensitivity on 122 cervical intraepithelial neoplasia 2 and greater samples. Specificity was assessed using 887 samples with twice-normal cytology. Inter- and intralaboratory reproducibility analysis was assessed using 525 samples. Finally, a time-and-motion study was performed to evaluate COR instrument performance characteristics.

Results
The Onclarity-COR was noninferior to the GP-EIA for both sensitivity (P = .0016) and specificity (P &lt; .0001). The intralaboratory reproducibility was 98.3% (κ = 0.96), and interlaboratory agreement was 98.5 % (κ = 0.96). The daily hands-on time for the COR instrument was 58 minutes, and walk-away time was 7 hours, 2 minutes per 8-hour day shift.

Conclusions
The Onclarity-COR instrument fulfills international validation criteria on sensitivity, specificity, and laboratory reproducibility. The Onclarity assay’s extended genotyping capability, together with its high-throughput characteristics, makes the COR instrument an excellent candidate for use in human papillomavirus primary cervical cancer screening.
