Abstract: Compressive strength of concrete at the age of 28 days is an important parameter for the design of concrete structures, waiting for 28 days to obtain that value is quite time consuming while it is important to ensure the quality control process. In this study an alternative approach using artificial neural network (ANN) model, is proposed to estimate or predict the compressive strength of concrete at 28th day from early age results. In the study concrete cubes of 1:2:4 were cast with different water-cement ratios (0.4, 0.5, 0.6 & 0.65) and their seventh and twenty eighth day strength were measured in the laboratory. In all, 400 cubes of 200 sets of cube crushing test were conducted. ANN model was then developed using the time series tool of ANN in MATLAB 7.12.0 (R2011a) using.....

Abstract: On April 6th 2020 the Kenyan government,imposed restriction of movement in and out of the Nairobi metropolis and Mombasa. The restriction of movement, caused a huge challenge in the management of the Mau Mau Roads Lot 1B project which had commenced on 18th June 2020.This was further complicated by the fact the inception/planning of the project had not incorporated an off–site friendly project management system in the Conditions of Contract (CoC). This paper aims to explore the process of identifying a sufficient Enterprise Resource Planning (ERP) system for the management of Mau Mau Roads Lot 1B. It seeks to guide the engineer in appreciating the dynamics involved.....

Abstract: Generally, the buildings are designed and constructed in various parts of the world. But not all buildings are green buildings that can save the environment and improve the climatic conditions around the world. To make existing buildings suitable for the environmentally friendly and sustainable development to nature. The various rating system is adopted for existing buildings like GRIHA, LEED, IGBC etc. The GRIHA rating system for the existing buildings have been studied which includes construction, operation and maintenance of the buildings for the Sri Sairam engineering college campus.

Abstract: Background: This paper investigates the deflection of micro- electro-mechanical system (MEMS) based sandwiched cantilever beam for piezoelectric actuation using eight of the popular lead zirconatetitanate (PZT)piezoceramic material. The simulation for the investigation was carried away in COMSOL multiphysicssoftware environment. For the investigation of a certain model, the lowest tip deflection is found to be 38.074 nm for PZT-8 and the highest tip deflection is found to be 82.965 nm for PZT-5H. Materials and Methods: A 2 mm thick flexible foam core is sandwiched between two 8 mm thick aluminum layers in this model of sandwiched.....

Abstract: India is a country with a large land mass, the 7th largest in the world. Its population is huge, it being the second most populous country in the world after China. Being a developing country with a huge population, there is an intense focus on construction activities which range from residential to commercial or infrastructure augmentation like bridges, roads, etc. Construction has changed from traditional to modern with the mud and mortar giving way to concrete and steel structures. Located 8 and 37 degree North latitudes, India is as a whole located in the Northern hemisphere but the climatic conditions are diverse, with most of the country experiencing a tropical/subtropical geography with warm to hot summers and pleasant winters. However, there are different climatic conditions with certain areas experiencing temperate climate with intense winters.....

Abstract: Test was carried out on the strength of steel and rattan by placing two (2) top reinforcements and two (2) bottomreinforcement's arrangement of rattan and steel splint of 8mm, 10mm, 12mm and 16mm diameter to check the adequacy and strength values of rattan and steel reinforced concrete beam after crushing. The potential of rattan cane as a possible replacement for steel in concrete beam were investigated. The main aim was to determine the flexural behavior of rattan cane reinforced concrete beam. Tensile strength test were also carried out on the rattan fiber samples and the corresponding steel of the same diameter to ascertain the strength differences. The load carrying....

Abstract: Buckling restrained braced frame (BRBF) is a distinct kind of bracing system in which the braces can reach its yield strength under tension and compression. Despite solving many problems of the conventional bracing, residual displacement is still the most disturbing issue caused by its low post yield stiffness. One way to solve this is the use of different steel materials in the steel core from which its name arises as hybrid buckling restrained braced frame (HBRBF). Most of the studies compare the performance of the two systems under far fault earthquakes. This study looks at the effect of the problematic near fault ground motions with its velocity pulses and high frequency content. Non-linear static and dynamic.....

Abstract: Optimization and product process layout plays a major role in small and big industries. This paper focusses on various methods and simulated theories which eventually lead to optimization and product process layout. The elements such as coolant properties, cycle time of the product on a particular machine, improvements in cutting tool, reduction in time required for product handling etc. The main aim behind researching such varied range of review papers was to study and understand the best possible as well as innovative parameters to lead to a positive output. Similarly, various simulation software's were used such as ARENA, Flex Sim, CRAFT, and CORELAP etc. in order to simulate the designed processes and furthermore validate them as well.
