Abstract: The development of high rise buildings and the need to provide more rigid structural systems to sustain severe lateral loads due to seismic and wind conditions lead to the necessity for mixed steel and concrete systems. This leads to the invention of Concrete Filled Steel Tubular Columns (CFST). Concrete Filled Steel Tube (CFST) is the composite section formed by filling concrete into a hollow steel tube. Extensive work carried out on CFST in past years have indicated...........

Abstract: The increase in concrete consumption increases the utilization of large quantities of energy and decreases the natural resources available. Ordinary Portland Cement which is used in the production of concrete produces large amount of green house gases. Sustainable concrete is the only solution to make environmental friendly concrete. Sustainable concrete is manufactured by using industrial by-products like copper slag, fly ash, silica fume etc.In this study ceramic waste and silica fume are used as alternatives to cement. Copper slag is used as alternative..........

Abstract: In this paper, a five fingered robot gripper is designed and modeled in 3D modeling software Solid works. Material analysis is performed on the gripper by applying the chemical composition and properties of given materials. Cost analysis is developing and analyzing cost data from separate business and estimating incremental and total resources indeed to support current and future business strategies. A robot griper is an essential element of the robotic system and it is designed to suit industrial application to typically grasp, carry, manipulate and assemble the components. The design of a gripper finger is a difficult task with many considerations such as task requirements...........

Abstract: Rainfall induced landslide has become a common phenomenon in Bangladesh causinghuge loss of life and properties almost every year. As landslide phenomenon in Chittagong City commonly takes place in the rainy season, it is worthy to find out other factors that affect slope stabilityrather focusing solely on rainfall. We investigated some engineering parameters like grain size, cohesion, and angle of internal friction of slope materials where the devastating landslides in.........

Abstract: It has been observed that above 60Kmph vehicle speed, the mirrors of two wheelers starts vibrating enough to make it difficult to identify what's behind. The vibrating mirror reduces the confidence of the driver to make moves. Shaky mirror and blurred image created safety concern for the rider and pillion rider. This paper revolves around the vibration analysis of "Two Wheeler Rear View Mirror" assembly. The aim of this paper is to study the different vibration modes of rear.........

Abstract: The utilization of recycled aggregates is becoming a common practice and a method to improve concrete sustainability. The use of a cheap filler as partial replacement of the Portland cement, which is a high energy consuming material, is another technique to further improve sustainability. The use of fillers is more beneficial in the case of high strength concrete where both water and space are limited to achieve full hydration of cement. In this work the behavior and properties.........

Abstract: This paper investigates the effect of metakaolin (MK) and silica fume (SF) on different concrete properties. Twenty-four different sustainable concrete mixes (fc=29 to 93 MPa) with and without metakaolin and silica fume were prepared with local materials in Egypt. Concrete mixes were cast with 0, 5, 10, 15, and 20% cement replaced by either metakaolin or silica fume..........
