Abstract: In contrast to subtractive manufacturing techniques like machining, additive manufacturing, also known as 3D printing, fast prototyping, or freeform manufacturing, is the process of adding materials to build items from 3D model data, typically layer by layer. The process variations have the greatest impact on the cost, productivity, and quality of additive components. Numerous studies have been conducted on the effects of process variables such as wire feed speed, voltage, and current. The welding process settings have a direct impact on the quality of components made via additive manufacturing. In this study, stainless steel 304L (the substrate) with dimensions of 220 x 140 x 8 mm and stainless steel 308L (the workpiece) with a diameter of 1.2 mm are used to create wall components using a 6-axis robot welding system from YASKAWA. SS308L is frequently utilized in gas pipelines, oil industries, and cryogenic applications. In this study, GMAW and CMT welding techniques are used to create SS308L wall components. The SS308L wall components' mechanical properties were examined. The GMAW and CMT procedures both use fixed parameters. Current, voltage, gas flow rate, wire feed rate, and torch speed are the fixed parameters. The impact strength of wall assemblies created using the CMTAW process is greater than that of GMAW wall assemblies.

Keywords: Wire arc additive manufacturing, 308L stainless steel, mechanical properties

Abstract: Bridges are the life-line of nation. Now a days any project not only serves the purpose of need, strength and serviceability but aesthetics is a factor that has occupied the major share in finalizing any project's demand. Thus curved, skewed, sleek, box girders are being constructed these days. Box girders not only look pleasant but also serve the purpose of strength. A parametric study is performed on concrete box girders having different skew angles. Further these box girders are analysed as post tensioned box girder having different post tensioning forces and comparison is made in responses obtained using CSI Bridge 2021 software. For this purpose, four different skewed alignments are considered 0⁰, 5⁰, 10⁰, 15⁰. Again, two post tensioned forces 400Kips, 600 Kips are applied. The various responses like torsion, shear force, deflection, bending moment about vertical axis, bending moment about horizontal axis, modal frequencies, longitudinal stresses at soffit at entire girder are studied. Then a tension check is performed to check the stresses coming on soffit of girder before and after post tensioning.

Keywords: Box Girder, Multi Cell, Nonlinear Analysis and CSI Bridge.

Abstract: In this research, we answered the questions like "What is A.I. ?", "Why Electric cars were overshadowed by motor cars ?", "How A.I. upgraded Electric cars ?", "What was the common public opinion on smart cars ?", "Pros and cons of smart cars".When we think A.I. in automotive industry, the first thing which comes to our mind is driver less cars. Though people trust A.I. in assisted driving cars, they would hesitate to buy a complete smart car without a driver or a manual control in it.Electric cars are gaining importance in terms of environment and budget, adding A.I. in it will escalate the user experience and strengthens the function performed on and by smart cars.

Abstract: This study explores the effect of physiochemical properties of pineapple peel oil (PPO) incorporated corn starch based edible coating and the effect of this oil incorporated starch based edible coating on the shelf life of fresh cut fruits and vegetables. Corn starch based edible coating was prepared using corn starch, distilled water and glycerol. The pineapple peel oil was incorporated at a rate of 1%, 2% and 3%. The physiochemical properties of edible coating such as the Total Soluble Solids (TSS), ph., titratable acidity and ascorbic acid content were analyzed. Weight loss and sensory analysis were used as parameters for testing the shelf life of coated fruit and vegetable in 0, 3 and 7 days. The study concluded that 3% Pineapple peel oil incorporated Corn starch based edible coating were provided an extended shelf life when compared to 2% PPO + Corn starch, 1% PPO+ Corn starch and uncoated sample. The uncoated sample showed a rapid deterioration with an estimated shelf-life period of 2 days at room temperature, based on the fast weight loss, color changes, accelerated softening and ripening, browning, and high incidence of decay. On the contrary, those treated with edible coating significantly delayed the above parameters related to postharvest quality losses, and storability could be extended up to 7 days at room temperature. Interestingly, the sensory analyses revealed beneficial effects in terms of delaying browning and dehydration and maintenance of the visual aspect of the sample without any detrimental effect on taste, aroma, or flavors.

Abstract: The most common type of pavement utilized in road construction is flexible pavement. By-products of crude oil are used to produce asphalt pavement, an organic material with binding properties. The country's development and growth rely on its ability to connect to its different rural areas. Flexible pavement provides the majority of connections; thus, improving the condition of bituminous roads is essential to avoid severe accidents on the roads. Given the situation, when waste materials like plastic and recycled asphalt pavement aggregates are growing daily, it is imperative to utilize this waste as much as possible so that the performance should either improve or remains stable as compared to conventional materials.

Keywords: Plastic waste, Bitumen, Modified plastic Bitumen, Recycled Asphalt pavement (RAP).

Abstract: For the analysis of spreading of the crime, a non-linear model has been suggested as well as stability analysis is performed in this paper. Under normal situations crime is modelled as a contagion spread of infectious disease. Here, the modelling is done by dividing the total population into non-susceptible, susceptible, criminal and jailed populations and the connection between them is given by simultaneous ordinary nonlinear differential equations. The interaction between them plays an important role and hence care has been taken while modelling. The threshold parameter R0 for the elimination of criminal activity is enumerated using the approach of the next generation matrix. Analysis indicates that when R0 1 indicates the endurance of criminal activity in the society. Numerical simulation along with the stability analysis is performed. However, various investigators have already worked in this field, but still there are vital possibilities for further research in this arena in the future.

Keywords: Crime, Equilibria, Mathematical Model, Numerical Simulation, Stability Analysis.

Abstract: All 3520 days permeate volume and trans-membrane pressure of an A2/O-MBR RWTP in Xi'an Siyuan University have been indiscriminately used to study an evaluation method of MBR hollow fiber membrane replacement. The industrial permeability, VMD, has been defined as a fraction with the numerator of permeate volume and the denominator of trans-membrane pressure, m3/ (1000-m2.day.kPa), without temperature normalization. Based on our practical operation, as membranes age, three phenomena can be observed simultaneously. The VMD is decreased 0.78 m3/ (1000-m2.day.kPa), about 4.28% annually； The TMP is increased 0.66 kPa, about 3.50% annually, and the present production capacity is decreased 47 m3 per day, about 2.47% annually； The frequency of cleaning events is increased. In a practical point of view, the membrane replacement interval is a technical and economic planned exercise. Even though, data used in this paper have come out with limitation, but the methodology used still be meaningful.

Abstract: Bridges are the major part of infrastructure allowing the flow of human beings, goods and vehicles. SHM has been widely applied in various engineering sectors due to its ability to respond to adverse structural changes, improving structural reliability and life cycle management. Structural health monitoring (SHM) is a process that aims at detecting, locating, and quantifying damage in structures at an early stage in order to avoid unexpected failure. Structural health monitoring aims to provide quantitative and reliable data on the real conditions of a bridge, observe its evolution and detect the appearance of degradations. Non-destructive testing (NDT) is a testing and analysis technique used by industry to evaluate the properties of a material, component, structure or system. It is often necessary to test concrete structures after the concrete has hardened to determine whether the structure is suitable for its designed use. The purpose of this study is to review Structural Evaluation of an existing bridge by carrying out non-destructive test named rebound hammer along the bridge by concerned authority to obtain the reduced compressive strength parameter of superstructure of bridge and modelling and analyzing it by FEM software specifically STAAD Pro and comparing the results such as bending moments, forces, and deflections and stresses and providing required repair and rehabilitation techniques.
