  • Simulation of Visual Servo Control on CRS Catalyst-5t Robot System

    This paper presents the position based visual servoing (PBVS) control system which govern the motion of the manipulator with an eye in hand configuration. the main core of the PBVS control scheme is the pose estimation process in which the relative pose (position and orientation) of the object with respect to the camera mounted on end-effector was estimated by two techniques (Classic POSIT and Kalman filter). CRS Catalyst-5t robot system has been selected for setting up the PBVS control system. The simulation software program has been built to evaluate the success of the simulated robot vision system in performing the required visual servoing tasks using the designed position based control scheme.

  • Speed Calming Using Vertical Deflections in Road Alignment

    In densely urbanized areas with intensive land uses, traffic calming is a vital safety countermeasure to avoid violation of permitted speed-limits in hazardous areas such as; approaches of un-signalized at-grade intersections and upstream of surface pedestrian-crossings at or nearby densely land-uses such as; schools, hospitals, worship houses, etc. Previous researches showed that speed calming is usually done by either horizontal or vertical deflections in road alignments. Horizontal deflections in road alignment could be achieved through narrowing carriageway width, adopting horizontal alignment to prevent over speed, etc. while vertical deflections in road alignment could be achieved through instillation of speed humps upstream to the required speed calming or temporary work-zones locations. This paper focuses on determining actual traffic performance up- and down-streams of speed calming countermeasures using vertical deflections in road alignment (humps and speed tables) to study the influence of their physical and geometric characteristics on traffic performance, in terms of speed profile and traffic flow, and also to extract some guidelines for their most suitable locations.

  • Behavior of Cold-Formed Z-Section Beams

    The effect of different parameters on the ultimate strength and behavior of cold formed Z-section beams has been studied. A finite element model for this beam has been prepared and verified by comparing its results with the results of some experimental studies. A parametric study is performed using the finite element model to study the effect of different parameters on the ultimate strength and behavior of such beams. A comparison between the nominal moments calculated using the finite element model, the Egyptian Code of practice (ECP-2001) and the American Iron and Steel Institute Code of practice (AISI-2001) is presented.

  • Water Purification Using Multiple Stage Filtration Technology

    An experimental model for the multiple stage filtration (MSF) process has been designed which consists of roughing Filter (RF) and slow sand filter (SSF) and located at Giza Water Treatment plant. The results indicated the purification of water with levels of contamination well above those treated by SSF alone, and high efficiency in turbidity removal (90-99%). The overall efficiency is increased by reducing filter media size or rate of filtration. Turbidity removal contribution of RF to overall removal is around 77% and around 19% for SSF. MSF can handle turbidity level up to 30 NTU and give effluent turbidity less than 0.5 NTU. At rate of filtration is higher than 0.25 m/hr, removal of turbidity deceases significantly. The SSF should be cleaned every two months to maintain a maximum head loss of 63cm. High levels of turbidity (above 10 NTU) causes clogging of SSF.
