Abstract: The current environment makes people very dependent on traditional air conditioning systems. But the problem with conventional air conditioning systems is to create suffocation when we use extra time due to the high moisture in the air. Here we implement a device. It reduces the relative humidity in the atmosphere, A liquid desiccant dehumidifier has been created with this in mind. One desiccant dehumidifier unit, air handling equipment, and desiccant handling equipment. The primary objectives of the present study are to determine the impact of inflow parameters on system performance and the ideal parametric conditions for moisture condensation rate. Many experimental studies were conducted to support this. The object of the work demonstrates that the moisture condensation rate rises with rising flow rate, desiccant concentration, and desiccant flow rate.

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.
Development of an electromagnetic actuator for haptic feedback in virtual reality applications
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.

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.

This paper proposes a methodology for Urolithiasis detection from medical image of patients using image processing techniques. Urolithiasis known as kidney stone in common terms, a disease where minerals in urine crystalize and form stones which is detected using lab results, medical imaging techniques and patient’s symptoms. It is one of the common diseases across the globe. The proposed method must be able to detect presence or absence of Urolithiasis from the medial image report thus eliminating manual examination done by radiologist or nephrologist. For this purpose, the input image is initially preprocessed to eliminate unnecessary details, noise, reconstruct and enhance image after which it undergoes segmentation using thresholding techniques. Finally, detection of presence or absence of Urolithiasis from ROI will be done using edge detection methods and ORB.
