Anila U, Manish Jose | pp: 11-14 | Download Paper | Show Abstract
Abstract: Pipe networks and ducts are necessary in modern buildings to support various services, including AC, telephone, electricity, water supply, computer networks, and sewage. Typically, these systems are situated below the beam and covered by the ceiling for aesthetic reasons, which results in dead space. To decrease the dead space in the floor area, ducts and pipes can be passed through the longitudinal and transverse openings in beams. The concrete located near the neutral axis of reinforced concrete beams is frequently underutilized, and this concrete can be substituted with lightweight material to decrease the weight of concrete. Incorporating a GI pipe to create a hollow section in the beam is another way to reduce the weight of the structure. This study examines the flexural behavior of reinforced concrete hollow beams under a two-point load and evaluates the suitability and flexural strength of these beam structures. Steel fibers improve the fracture behavior of members, and the further studies compare the fracture parameters of fiber reinforced hollow beams with solid beams.

Namya Musthafa, Yazid Musthafa | pp: 15-18 | Download Paper | Show Abstract
Abstract: In recent decades, the use of electromagnetic actuators and haptic sensors has increased widely. An electromagnetic actuator is a machine that produces mechanical force or motion using electromagnetic fields. Electrical energy is transformed into mechanical motion or force by electromagnetic actuators. Haptic feedback, a sort of sensory feedback, which is commonly referred to as tactile feedback, uses touch or other physical sensations to provide information or indications to a user. It is frequently employed in human-computer interfaces where it can give users a more engaging and interactive experience. There are many different techniques to transmit haptic input, including vibrations, pressure, temperature changes, and changes in texture. Devices and systems can benefit from haptic feedback to improve their usability, functionality, and security. This study intends to show the creation of an electromagnetic actuator that offers haptic feedback in applications for virtual reality. The actuator is made to replicate the touch and give users of virtual environments a more realistic experience. The design procedure, including the choice of materials and the creation of the actuator, is described in the paper. The performance of the actuator is assessed based on its power consumption, frequency response, and force and displacement capabilities. The findings indicate that the actuator can produce accurate haptic feedback in reaction to virtual events, making virtual reality applications more immersive and lifelike. As it provides a more logical and natural interface that can improve the user’s immersion and involvement in virtual settings, this research has significant implications for the field of virtual reality.
The State of the art review on Concrete Sandwich Panels
M. Raga Sudha, A. Muthadhi | pp: 19-27 | Download Paper | Show Abstract
Abstract: Concrete sandwich panels (CSPs) are composites, consisting of three main parts the skin, core and adhesives/connectors. Skin faces comprise two top and bottom concrete wythes, which are thin, stiff and strong; whereas the middle core part was thick, light and made up of weaker material, characterized by high thermal resistance which is boned or fixed together with adhesives or connectors. CSPs can be manufactured either cast in situ or precast and affixed to any type of structural frame. It can function dually by transmitting load and insulating the structure. Hence, it was thermally efficient and used as replacement cladding for renovation works. Nowadays most studies on CSP report on its structural testing, which focus mainly on the load transfer mechanism between concrete wythe skin and core material by composite and/or non-composite action to the attached structural component. Sandwich panels may also be intended to carry the self-weight of the buildings and critical studies from various pieces of literature focused on the structural performance of sandwich panels are reviewed herein. This critical review also focuses on the latest advancements in the development of textile-reinforced concrete sandwich panels with various types of mesh reinforcement that achieve excellent flexural and impact strength properties. But still, there is a need for further studies on different types of adhesives and connectors used between concrete wythe and core material of concrete sandwich panels and thermal validation of novel CSPs.

Abstract: The rolling process is one of the most important phases in the steel industry, and there will always be wear between the material travelling between the rolls and the guide roller. The guide roller’s function is to guarantee that the material travels through the rollers with minimal damage and nearly a liner course. As a result, there is a provision for inserting a layer of coating to boost the productivity and life of guide rollers. The goal of this research is to create a Molybdenum- based coating for D2 tool steel, which is already used in the steel industry. The pin on disc wear test and Vickers hardness test were performed to compare the results of the uncoated substrate and the coated substrate to demonstrate that the coated substrate’s wear resistance and hardness had enhanced compared to the uncoated substrate. Coated and uncoated specimens are placed in molds and polished against graft papers to provide a mirror-like finish for the thickness test and Vickers microhardness test. A high – resolution microscope found that the molybdenum coating thickness was 250 microns, with particle sizes ranging from 10 to 40 microns, and the Vickers hardness test revealed a 20% increase in hardness. The pin on disc wear test consisted of 54 trials using a full factorial design, with 27 coated and uncoated specimens. To achieve the desired results, three factors were chosen: Load, Sliding Velocity and time. The parameters for the three components were (1kg, 2kg, 3kg), (200 RPM, 400 RPM, 600 RPM), and time (15mins, 30mins, 45mins) accordingly. The diameter of the track was fixed at 40mm. The weight loss due to wear for the uncoated specimens was greater than that of the coated specimens after a total experimental duration of 27 hours of experimentation and 54 trials, showing an improvement in wear resistance.
Effect of Slope Geometry on Energy Dissipation for Stepped Spillway
Prachi Dharmadhikari, Sumit Gandhi | pp: 35-41 | Download Paper | Show Abstract
Abstract: Experimental study has been done for the analysis of flow over stepped spillway with three different models. Study reflects the behavior of flow characteristics namely sequent depth ratio, relative energy loss and relative length of jump against varying Froude number. Effect of height, width and length of steps plays a significant role in dissipating maximum energy under nappe and skimmimg flow conditions. Importance of air entrapment and entrainment were also discussed to protect the structure against cavitaion damage. Difficulties faced during the prediction of length and roller jump due to presence of turbulence and eddies at the channel bottom were discussed with existing literatures. Comparison has been made between non-aerated flow zone and point of inception against reduction of step height under same discharge. Also, pseudo-bottom air concentration is explained for entrapped and entrained air concentration. Present approach represents the flow properties in dimensionless form and hence can be applied to the field condition directly.

Shikhar Goliya, Sumit Gandhi, Yogesh Iyer Murthy | pp: 42-47 | Download Paper | Show Abstract
Abstract: Glycerine is well established as a Phase Change Material (PCM). But very little is known about its effects on the structural performance of the resulting concrete. In this paper Glycerine is added at 0 %, 2.5 %, 5.0 %, 7.5 % and 10 % by weight of water and the fresh and hardened properties such as compressive strength at 7, 28, 56 and 90 days and sorptivity are experimentally evaluated. The fresh concrete produced showed a drastic reduction of slump with increasing percentage replacement with 74% reduction at 10% addition of Glycerine compared to the control mix. Further, the compressive strength also showed a drop in strength by 34.5% with respect to control mix for 10 % addition of Glycerine. The compressive strength determined at 7, 28, 56 and 90 days showed an optimum Glycerine content of 7.5% on all days. The sorptivity values are found to decrease with increase in amounts of Glycerine. The percentage reduction of sorptivity values from 2.5 % Glycerine to 10 % Glycerine was found to be approximately 6 %. It is thus concluded that addition of Glycerine to concrete results in a more watertight concrete compared to the standard concrete.

Poonam Juneja, Almaas Zafar, Vyom Dev Chhabra, Ayush Kumar | pp: 75-78 | Download Paper | Show Abstract
Abstract: Stress is a typical human reaction that everyone experiences. In truth, the human body is built to experience and respond to stress. When we face changes or challenges, our body responds physically and mentally. That is the result of stress. Humans have been subjected to much stress in the last ten years, which is why stress measurement is becoming increasingly crucial in our daily lives. It is critical to recognize stress since it is a big worry, and it also helps to raise awareness. The physiological data plays a significant part in detecting human stress since alterations in the data make it extremely easy to learn about stress levels as well as anxiety, which appears first and is followed by stress. When the data is combined with machine learning and deep learning algorithms, detection becomes more accurate after training on the training data. The major goal of this research is to find a unique accuracy of stress detection using physiological data and to compare models using the acquired accuracies.

M.Reena Ivanglin, R.Pragaladan | pp: 85-98 | Download Paper | Show Abstract
Abstract: The integration of expert systems, mobile intelligence, and the cloud for diabetes diagnosis was the study’s main objective. An expert system is a computer programme that makes use of a knowledge base and an inference engine to solve problems considerably more quickly and effectively than they would otherwise. To lessen the limitations of mobile applications, the cloud has provided developers with a variety of services to create, manage, and deploy. Because of population expansion, ageing, addiction, urbanization, obesity, lack of exercise, and other complex diseases, there are more people with diabetes than ever before. Furthermore, these issues are made worse by a lack of specialists, inaccurate diagnoses, and inadequate medical facilities. Thus, diabetics require ongoing care such as dietary restriction, exercise, and insulin management. A hospital’s knowledge was drawn from in order to create the prototype using a purposive sampling technique. Case studies are chosen for testing and assessing the prototype system in order to determine whether or not it is accurate and meets end-user criteria.

Abstract: Cement is an inevitable constituent used in the production of concrete. Cement production results in the emission of an equal amount of carbon-dioxide into the atmosphere which may be serious threat to the environment in various forms. Admixtures have also been recognized as important components of concrete used to improve its performance. Most of the admixtures are available in market in the form of chemical composition. These chemical admixtures are very expensive and severely pollute the surrounding environment. This paper aims at the development of a sustainable concrete by replacing cement with natural egg shell powder and using Terminalia Chebula (Kadukkai) as a natural admixture. The concrete design mix considered is M30. The specimens were cast and compressive strength of 7th,14th and 28th day are determined. From the results, optimum mix percentage was obtained, on which split tensile strength, flexural strength test and rapid chlorine permeability test were conducted and their performance were analysed. This study proves that eggshell powder along with Terminalia Chebula is a good natural replacement for both cement and chemical admixture.

Abstract: IoT-Based Prison Break Monitoring and Alerting System using RF (Radio Frequency) is a system that achieves a Microcontroller based circuit to fulfill the module using RF technology. Each inmate is equipped with a non-detachable wearable device consisting of RF transmitters to detect their presence in the premises. We install RF transceivers at strategic location within the prison and the gateway for relaying data to the central monitoring system which is responsible for analyzing data and triggering alerts in case of escape attempts. The central monitoring system is fed with data to scan through all the prisoners mounted with an RF transmitter who transmits their unique prisoner code wirelessly to keep the overall system in synchronization. If a prisoner moves out of range, the integrated system is unable to encrypt the data. As a result the receiver circuit sends the details of the prisoner to the officers alerting portal which in turn gives instant alerts and catches the prisoner before he runs a few meters away from the premises. The IoT Gecko is interfaced to build the alerting portal which receives data from monitoring devices and displays alerts or buzzers through the internet. Thus our system offers a comprehensive and customized approach to prison security which provides real-time monitoring and alert for any security breaches by enhancing public safety.

Snigdha Satapathy, Vishal Guru, Ramesh Chandra Nayak | pp: 116-120 | Download Paper | Show Abstract
Abstract: It is necessary to provide energy in different areas of use such as Cars, rice mills, flour mills, which use different transmission systems such as belts, chains and gear, it is found that the more power can be transmitted in gear drive than the other two, power transmitted by gear drive provides 100% efficiency, due to less slip occurs it is used in gearbox and in different machines. Belt drive can transmit the same power ratio, but the slip occurs in due course of time and there is the stretch in the belt, which may need replacement. Chain drive gives the better performance than the belt drive in this respect. So according to the requirement and the distances between the drivers to driven different methods can be used. In shorter distance gear drives gives the best result as the less slip occurs. The speed ratio of gear drive generally; driven/driver=T2/T1. More modification is required in belt drive than the chain and gear drive. In this work a model has been developed where three types of transmission systems have been placed in a single base. The purpose of this work is to calculate the velocity ratio of different drive systems with single input.

Cyclic and Buckling Analysis of Concrete Filled Steel Pipe Piers with Composite Connection
Aiswarya T P, Dalmiya Rajan | pp: 127-132 | Download Paper | Show Abstract
Abstract: Composite steel-concrete connections are used to protect critical welded interface areas between steel pipe piles and cap beam bridge piers, and can increase the shear capacity of a steel bridge, improving its performance. In this paper, a numerical study using the finite element method was conducted to evaluate the seismic performance of concrete-filled pipe piers with composite steel-concrete connections designed to protect against local buckling phenomena. It was found that the use of composite connections minimized local failure of the steel components by providing confinement through concrete action. Strengthening the connection by filling the hollow pipe pile with concrete helped avoid local buckling and increased the shear force capacity. Buckling and cyclic analysis showed that concrete-filled pipe piers with composite connections reduced buckling while avoiding unfavorable failure modes. Overall, the use of concrete-filled pipe piers with steel-concrete composite connections can improve the performance of bridges, especially in earthquake-prone areas, contributing to ongoing efforts to strengthen bridge infrastructure.
FLEXURAL BEHAVIOR OF CONCRETE COMPOSITE BEAM WITH DIFFERENT CONFIGURATION OF RIGHT-ANGLE TRIANGULAR (TTR) CONNECTORS
Arsha M, Neethu Joseph | pp: 133-137 | Download Paper | Show Abstract
Abstract: In composite steel-concrete beams, shear connections are crucial. Fundamental parts of composite steel-concrete columns are shear connectors. Their purpose is to create a decent amount of interaction between the steel profile and the concrete slab. The majority of shear connections are welded to a steel profile’s flange and set into the concrete component. By doing this, the shear connectors prevent the components’ steel-concrete interface from transferring longitudinal and transverse forces. The right-angle truss connector is a newly developed shear connector that offers effective structural performance at an affordable cost for both production and installation. Studies that analyze this connector’s behavior in greater depth must be developed, though, in order for use in beams that combine steel and concrete. In order to assess the Right-Angle Truss connector’s shear resistance, this research will vary certain parameters that are necessary for the connection of composite steel-concrete beams. Study was also done on the connector’s application orientation that offers the most shear strength. This also involves using the ABAQUS software to analyze various types and sizes of shear connectors.

Abstract: A construction project is started, coordinated, and completed from beginning to end while staying on schedule, within budget, and up to the required quality standards. This study aims to examine the need for risk assessment at construction sites in Kerala, India, and to demonstrate the usefulness of various methods, including the Relative Importance Index (RII) Test, the Importance Index (IMPI) Test, and the Fuzzy Dematel in analysing survey data. The survey was conducted through questionnaires administered to workers, supervisors, and managers at selected construction sites in the state. The results indicate the crucial need for risk assessment to minimise cost, time, and other risk factors. The RII Test and IMPI Test were used to rank the factors according to their influence, while the Fuzzy Dematel method was used for a more detailed analysis. The study highlights the importance of risk assessment at construction sites and provides a framework for conducting such assessments. It can serve as a useful reference for construction companies and policymakers in developing effective risk management strategies in the construction industry. Despite the high risk involved in construction projects, there is a lack of studies on risk assessment, making this study a valuable contribution to the field.
