Determination of the Flow Velocity Resistance in Non- Submerged Woody Plants
Abstract: Vegetation on the bank of a river or stream has a major influence on resistance, velocity distribution,and turbulence force. The resistance to flow in open channels depends on different channel and flow parameters. Out of many factors, vegetation is the mainly important parameter in open channels. In this study have been five points to measure the velocity in the channel. The experimental work has been done by a rectangular channel …

Review of Thermodynamic Effect on Atmosphere
Abstract: The study of heat-to-work transitions that occur in the earth's atmosphere and manifest as weather or climate is known as atmospheric thermodynamics. The laws of classical thermodynamics are used in atmospheric thermodynamics to describe and explain phenomena such as moist air characteristics, cloud formation, atmospheric convection, boundary layer meteorology, and vertical instabilities in the atmosphere. Thermodynamics is more specifically concerned with the conversions of energy into mechanical energy and mechanical …

Study and Characterisitics of Different GVF Profile of Rectangular Channel
Abstract: This technical note presents the equation for one-dimensional gradually-varied steady flow profiles with constant discharge, in a rectangular-section prismatic channel of constant roughness and small longitudinal slope. The flow profile differential equation was transformed by means of a polynomial approximation and then, by an algebraic procedure followed by the integration of the equation, the solution was obtained. This solution was applied to a particular case which, through a comparative analysis, …

Laser-induced Phosphorescence Photobleaching Anemometer for Microfluidic Technology Instruments
Abstract: In this article, we have established a new, non-intrusive flow velocity calculation approach focused on photobleaching of a fluorescent dye for micro-fluidic systems. The time of existence of the fluorescent dye in the laser beam depends on the flow rate which roughly relates to the time of decay of the photobleaching of the dye in the laser beam. The time of residency is inversely proportional to the speed of flow. …

Scheme and Improvement of Topography Observation Carter Device Based on ATmega327 for Military Applications
Abstract: The goal of this endeavor is to create a mobile robot that can transport a surveillance camera over difficult terrain. It is often difficult to build mobile robot locomotion systems for unstructured environments, especially when moving across uneven or soft terrains or up obstacles is necessary. In order to assist designers in choosing the best option for particular operational needs, this project aims to examine the state-of-the-art in locomotion mechanisms …

Comparative Study of the Nature of Slag in the Formulation of Concrete Pavers
Abstract: The steel mill generates about 8000 tons/year of slag by transforming scrap metal to produce more than 60000 tons/year of wire rod and steel reinforcing bars. These co-products are stored or used for backfill. With this almost inexhaustible slag deposit, Morocco has a valuable resource thanks to its high content of silicates, lime and metal oxides. This has led to the attempt to valorize it in the manufacture of paving …

Experimental Investigation of MRR and Surface Finish Using Abrasive Jet Machining of Aluminum Alloy 7475
Abstract: In this thesis, different experiments are performed on aluminum alloy 7475 by varying various parameters such as pressure, sand feed, transverse speed and standoff distance, i.e. nozzle-to-work-piece distance to determine material removal rates and surface finish. Optimization is done using L9 orthogonal array by Taguchi technique to determine better parameters to obtain maximum removal rates and minimum surface roughness. The parameters considered are transverse speed 50, 100, 150 mm/min; standoff …
