This project is about water level indicator using raspberry pi. In this project we used led to indicate the different levels and the raspberry pi to display were exactly the level is at in terms of percentages. The simple water level indicator will activate an active buzzer which will make a continuous noise when a certain level of water is reached (maximum).
Abstract: This paper presents the application offractal theory, especially fractal dimension to the formation of sawdust particles during operation with four detailed cases, which helps us to understand the distribution of the sawdust particles inhaled by sawmill workers and remove the effect of toxicity on their body quickly. Pattern of formation of sawdust in human lungs and other parts of the body (in fast branching rate) is described with a practical case study in a developing country. A...
ABSTRACT This study was conducted to develop a Power Tiller Operated Rice Combine Harvester (PORCH) for small holder farmers in Tanzania. PORCH can be attached to a power tiller during harvesting operation and detached to give the power tiller a room for other operations. The study aimed at designing, construction and testing performance of PORCH prototype.Design specifications and drawings were developed and prototype was constructed.The performance of PORCH prototype was tested in Lower Mo...
This thesis introduces full filled description for fifth-generation technology, here concentrated on massive MIMO technology in detailed at channel detection. However, channel illustrated carefully, described how to estimate and detect the channel. By using both algorithms least square and minimum mean square error for channel estimation while zero forcing and minimum mean square error for channel detection by analyzing and measure their performance using BER for MIMO 2x2, also it shows...
ABSTRACT Flexible AC Transmission Systems (FACTS) have been conceived to increase the transmissibility of electric power without the necessity of building new transmission iines. An important family of controllers proposed for FACTS are based on high power solidstate switches, such as the gate-tuni-off thyristor (GTO), which is presently rated at 6kV, 6kA. The FACTS controlier operates at the transmission voltage, in the order of 5ûûkV, and it rnust be mted at hundreds of MVA. The research...
Abstract An investigation is presented into the mechanisms governing both the ageing and axial cyclic loading characteristics of displacement piles in silica sands. The thesis considers first the state–of–knowledge regarding the axial capacity of displacement piles in silica sands. Three main areas of uncertainty are identified; the stress regime setup by installation, the mechanisms of ageing that lead to capacity increases with time (set-up), and the effects of axial cyclic loading. Ne...
This research presents a building management system (BMS), which is the key module in order to perform the controlling and automation. The main area of this BMS focuses on switching and controlling of the power input/output, besidethis security. Modern building services systems are an integration of mechanical, electrical and control components. In the world of today, various subsystems in a big building have been traditionally operated separately, each with their own Information Techn...
A full analysis and design theories have been reviewed conducted to determine response of a buried corrugated steel structural plate culvert for four exceptional shapes as; a round pipe, horizontal ellipse, arch andlow profile arch. The select of culverts span, cover, and exceptional live load have been applied and all were have the same value. AASHTO LRFD Method has been used to measure the result of analysis and design by using manual and computer program techniques. Data collected by�...
ABSTRACT Pavement markings are lines drawn on a pavement surface to provide vital information to road users pertaining to lane restrictions and vehicle movements, which if adhered to, results in improved safety and smooth travelling to road users. Pavement markings’ visibility is quantified into a parameter called retroreflectivity, which is a measure of how well the markings can be seen by road users. The importance of the factors affecting pavement markings differs from one publication t...
Abstract A novel study on biomass-air gasification using a horizontal entrained-flow gasifier and catalytic processing of the product gas has been conducted. The study was designed to investigate the effect of catalyst loading on the product gas. The use of a horizontal entrained-flow gasifier reactor was used to assess the effect of the gasifier reactor orientation on the gasification process. Both experimental and computational fluid dynamics (CFD) approaches were employed. The gasificatio...
ABSTRACT Oilseed sunflower is one of the major vegetable oil sources. The residue after the extraction of oil (defatted meal, DM) contains a substantial amount of nutritious protein which is recoverable by extraction and precipitation methods. For effective recovery of the solid proteins from the solids-liquid suspension, it is imperative to have large particles with a narrow spread in their size distribution and high solids concentration. In this research, up to 97 % w/w and 65 % w/w of the...
ABSTRACT This study utilized correlation and distribution analyses to investigate the acceptability of application of two fractal dimension estimators to characterize the waveforms originating from excited nonlinear pendulum. Parameters selection sensitive simulation of the excited nonlinear pendulum waveforms was performed with the constant time step fourth order Runge-Kutta algorithm with codes developed in FORTRAN90. However, the waveforms validated by Gregory and Jerry (1990) and treate...
The Sudanese air force college trains its pilots using a world renowned light aircraft for basic pilot training called UTVA-75, during operation in the climate of Portsudan the exhaust tubes experienced failure in the shape of cracking and therefore become dangerous to operate. The study tackles the issue from a material point of view, as properties that eliminate or reduce cracking or any failure are essentially material properties. The research examines material selection methods to ...
ABSTRACT Although there are many computer codes available for analysis of fluid transients, only. a few are known to be applicable to linebreak situations and their scope is limited. There is, therefore, still a big potential for development work in the subject. Discrepancies between different models which have been developed have mainly centred on the assumptions used in developing the basic partial differential equations of flow, and subsequent simplifications; the thermophysical model use...
ABSTRACT The aim of this work is to determine the mechanical properties of cold drawn low carbon steel subjected to full annealing. The specimens were slowly heated up to a temperature of 9000C followed by soaking treatment of 60 minutes under this temperature in a muffle furnance. Tensile, charpy and Brinnel hardness tests were conducted to determine the yields strengths, tensile strengths, impact strengths and hardness of the annealed steel. The yield strength, tensile strength, hardness an...
