Abstract: Researchers are currently conducting several studies in the field of navigation systems and sensors. Even in the past, there was a lot of research regarding the field of...

In an effort to find solutions for global energy crisis, an analysis on a helical vertical axis wind turbine was conducted with the consideration of renewables and energy efficiency. This study was carried out in two steps: the realization of the analytical calculation of a helical wind turbine power output which then informed the design and constr...

This effort examined the potential of winglets on wings in aircraft for the reduction of induced drag coefficient and the increase of lift coefficient without increasing the span of the wings. In this study, the aerodynamic characteristics of an airfoil wing having winglets have been studied with the help of simulation software ANSYS Fluent. Here,...

One of the elements which decide the existence of all living things is water. So, every nation is trying to find a more reliable source of water. The main objective of this study is to increase the productivity and production time of a single basin solar still within the same structure. An experimental performance analysis of modified solar still (...

This paper clarifies the concept of the "Multi-Purpose Mechanical Cutting Machine "mainly carried out for industries which are production-based. The industries are basically meant for the production of useful goods and services at low production cost, machinery cost, and low inventory cost. Different types of manufacturing operations are carried ou...

This paper deals with the Design, Construction and Performance Test of a Manual Timber Sawing Machine. It does not require any specific input energy or electric power. In this paper, human power plays a vital role. This paper consists of a larger sprocket that rotates with the help of human powered pedal. The smaller sprocket is connected to the pl...

Any airplane needs airfoils because they must reduce drag and produce enough lift to keep the aircraft in the air. Up until now, it has been challenging to develop an airfoil with the necessary aerodynamic qualities. Through experimental investigation, our work compares the aerodynamic characteristics of NACA 4412 and NAC 0015. Our study aims to in...

Energy plays an important role in human life, but it is hard to produce and costs a huge amount of money to execute. The fundamental aim of this paper is to develop a low-cost efficient energy source using Dhaka city drainage water by applying the water vortex method. This study is the analysis and design of a basin structure that can form a gravit...

In this paper, human power plays a vital role. This paper consists of a larger sprocket which rotates with the help of a human-powered pedal. The smaller sprocket is connected...

Monitoring weather plays a crucial role in human life, making the collection of data on climate changes imperative. This paper aims to develop a weather station to monitor climate parameters in off-grid regions. The project includes sensors for detecting temperature, humidity, rainfall, LPG levels, carbon monoxide, smoke, altitude, and barometric p...

With several years of research on solar cell development, the energy conversion efficiency has seen a great improvement but it is still a big problem to design an eco-friendly cost-effective solar cell with high conversion efficiency. For eco-friendly earth-abundant solar cell fabrication, Sulphur-doped α-Fe2O3(0001) has offered a very promising ab...

As fossil fuels are decreasing day by day, renewable power turns out to be the main energy source. Anyway, the interest is still lower than expected. Among them, one of the newest energy-gathering techniques is changing the mechanical energy from falling raindrops into power. This task focuses on the small, creating power with the help of falling r...

In the aerospace industry, the structures are subjected to significant loads and extreme conditions whilst being required to be lightweight and resilient. Metallic foams seem to meet these criteria. However, their usage in the aerospace applications is not as common as one would expect. To explore a potential application of foams, this study evalua...

This paper presents an approach to the development of bipedal robotic control techniques for multiple locomotion behaviors. Insight into the fundamental behaviors of human locomotion is obtained through the examination of experimental human data for walking on flat ground, upstairs and downstairs. Specifically, it is shown that certain outputs of t...

This research describes a hybrid robotic system combining hard and soft subsystems. This hybrid comprises a wheeled robot (an iRobot Create; hard) and a four-legged quadruped (soft). It is capable (using a simple, wireless control system) of rapid locomotion over flat terrain (using the wheeled hard robot) and of gripping and retrieving an object (...

The underwater environment poses a difficult challenge for autonomous underwater navigation. A standard problem of underwater vehicles is to maintain its position at a certain depth in order for it to perform desired operations. An effective controller is required for this purpose and hence the design of a depth controller for an Unmanned Underwate...
