CHAPTER ONE INTRODUTION 1.1 DEFINITION An inclined plane is a simple machine with no moving parts that helps one to do work. It is simply a straight slanted used for raising heavy loads more easily other than lifting it vertically. 1.2 WHAT IS A MACHINE? A machine is a device or system, which enables work to be […]

Abstract This work focuses on the design and construction of a conical screen centrifugal filter for the separation of groundnut oil slurry. The major component of the machine is the rotary conical screen which separates the pure groundnut oil from the slurry via centrifugal filtration. Sludge particles were removed from the slurry through the open

CHAPTER ONE INTRODUCTION 1.1 BACKGROUND OF THE STUDY Motor vehicle infraction has become a growing concern in Nigeria, with the increasing number of vehicles on the road and the challenges associated with enforcing traffic regulations. As a response to this issue, the implementation of motor vehicle infractions analysis has gained prominence. Nigeria has experienced rapid

Background: In recent years, civil aviation has experienced intense growth, regional or peripheral airports have been built or expanded to operate new routes. In the Portuguese case is no different, the two main airports (Porto and Lisbon) are close to the limit. Furthermore, there is a certain degree of isolation in the Central and Interior

Patterns of riparian hydraulic gradients and stream-groundwater exchange in headwater catchments provide the hydrologic context for important ecological processes. Although the controls are relatively well understood, their dynamics during periods of hydrologic change is not. We investigate riparian hydraulic gradients over three different time scales in two steep, forested, headwater catchments in Oregon (WS01 and
Quantifying flow resistance is important for understanding and predicting energy and momentum transfer processes in natural environments such as ice-melting in the polar ice sheet and sediment transport in mountain streams. Flow resistance represents the retarding forces experienced by flow and the associated energy loss (dissipated through heat) in these systems. Flow resistance is mainly
We investigate the ability to enhance flood inundation medium-range (0-7 days) forecast maps through weather ensembles and statistically water surface elevation (WSEL) postprocessing. To generate the flood forecast maps, a one-dimensional hydraulic model (HEC-RAS) is coupled to a regional hydrological ensemble prediction system (RHEPS). The RHEPS is in this case comprised by: i) weather ensembles
ABSTRACT There is great potential for using ensemble weather forecasts to improve hydrological predictions across spatial and temporal scales. To realize this potential, research is needed to formulate, assemble, and assess a full (i.e. accounting for the complete hydrometeorological forecasting chain) ensemble hydrological system and test how different system components can best contribute to improving

ABSTRACT There is a need to better understand the safety implications of geometric improvements on rural, two-lane highways. Funding for transportation safety improvement projects is often limited so it is important to estimate the relative safety effectiveness of each proposed improvement and select those that are likely to produce the greatest benefit. Safety, efficiency, and
