Development of smart wall painting robot
No full textWall panting is very important for decoration of all Egyptian houses and is usually done by hiring a human painter. However, wall painting is a tedious, exhausting. boring and hazardous for humans. Therefore, there is a global need to build a robot that can help people to improve their life by having higher quality painting besides saving health of labor and time. Wall painting process is an ideal candidate for automation. Though few trials had been made to develop a wall painting robot, but no product had matured yet to the stage of commercialization. In this project, we carry on the mechanics design of a new painting robot using roller for indoor wall painting. The main criteria for our design are simplicity, rigidity, stability, user friendly interface, light weight, speed and cost This robot will paint walls by using a roller fed with paint from a pump. The roller scans the wall vertically while the robot mobile base will move autonomously inside the room walls to finish painting. The robot consists of a differential drive base over which is attached a linear cascaded lift mechanism, which lifts a painting x-y stage to fixed heights of the wall. The x-y stage then scans a fixed area of the wall with its tip fitted with standard pump fed roller. The design is made such that the heavier lift mechanism is subject to less motion and then less wear compared to the light x-y stage. The robot is implemented with simple control and user interface. The vertical scan of the robot is completed in 27 seconds which resulted in a painting rate of 3 m2/min and the robot weighs 60 kg which ensures its portability for indoor applications.Mohamed abdellati

Nameless Field (bahariya formation) Western Desert of egypt
No full textTarget:Apply the ideal ways to evaluate and development of a field area BAH formation And ideal way to design a well in order to achieve all of the required technical data during by meaning of minimizing reservoir impairments and damaging. Given Data:* Regarding offset Data
Requirements:*Volumetric Estimation *Formation Evaluation *Drilling Prognosis *Tubing Size Selection *Suitable Artificial Lift SystemThis field is faulted anticline structure located in the Western Desert. The field produces from different layers mainly shaly sand and sand with different thickness. The main producing formation is Baharyia which will present the main target formation. This report is talking about evaluation and development of an x-field area on Baharyia formation western desert in Egypt with several drilled wells, The development will occur according to the study of geology and the volumetric estimate, offset data of drilled well in the field to design a well in order to achieve all of the required technical data during and post drilling operations as well as been reservoir friendly by meaning of minimizing reservoir impairments and damaging , formation evaluation, reservoir engineering, and production engineering. The study and the evaluation on the x-field will give a view of next step of reserve calculation and development plans to start water flooding development based on the interpretation of the given items

Design of Building Manament System (BMS) for Central Air Conditioning
No full textAbstract It's all about the need of Building Management Systems "BMS" and how BMS controls many systems as examples of HVAC systems, fire systems, lighting systems, and plumbing systems of malls, hospitals, big facilities The problem that needed a solution in the Faculty of Pharmacy in Future university abounded cases of fasting students m the laboratory was caused by gases resulting from chemical reactions n the faculty labs Hence a design plan of HVAC systems was conducted in order to control the gases waste circulation and achieve building and to reduce the power consumption the characteristics of the fresh air ventilation inside the There are three man devices of BMS system to be designed, Management devices such as server and work station (PC) or laptops, Automation devices such as Automation level control and ns expanders, LGR (Router), and LON to BACNET router / gateway Field devices such as Sensors, cooling coil Supply and return fans, Motorized Dampers, Duct Smoke detector, Heat exchanger Pre &Bag fitters The design pan of the project s based on Chilled Water System which consists of Ar Handlin Unit (AHU), chillers and pumps, in order to complete the cycle of BMS sensors were used to fulfil the goals of the project At the end of the project we will discuss the purpose of our design as follows :

Comparison of image analysis methods to determine the optimum loading of flighted rotary drums
No full textThe loading state of a flighted rotary drum strongly affects its overall performance. Hence, assessing the optimum (design) loading needed is a critical issue. In the present work experiments were carried out to assess the opti- mum loading of a batch rotary drum (0.5 m diameter and 0.15 m length) furnished with rectangular flights. Dif- ferent solid materials (free flowing), rotational speeds (from 1 to 5 rpm) and flight tangential/radial length ratios (0.375 and 0.75) were researched. The experimental work mainly relied on recording videos in front of the drum at different operating conditions. Then by means of image analysis tools the results were drawn. Two methods of image analysis were used and compared: manual and automated with many advantages over the methods pre- viously found in literature. However some problems were found when applying the automated method on the current experimental work images. Indicating that a new experimental technique should be developed in the fu- ture to facilitate both manual and automated methods

A Proposed Load Balancing Technique for Cloud Computing
No full textThere are multiple challenges that influence and obstacle the rapid adoption of cloud computing infrastructure, one of these critical challenges is the low CPU utilization ratio in cloud data centers, which does not only cause a performance degradation, but also reduces the profit margin of cloud providers by raising the cost of the service provided. and leads to increasing the power consumption which causes a global warming and endangers the human life on Earth. Therefore, we need a performancepower solution to minimize the negative impact on cloud computing so as to achieve the Green Cloud Computing (GCC). To do this, the study Proposed Cloud Performance Load Balancing (CPLB) Model which can be of great help as it adopts a technique that intends to maintaining the service level agreement (SLA) and the Quality Of Service (QOS) between the cloud service providers and cloud customers and make energy conservation in the Cloud Data Center.
The previous studies describing that the CPU utilization is important factor for overall system performance and cost. Greater CPU utilization produces higher response times for load dependent resources, and how the energy usage of servers in the U.S. doubled between 2000 and 2006 and how it reached to 61 billion kilowatthours (kWh) in 2006.With the fact that is only 30% of servers in data centers are fully utilized while the other 70% are still in idle state. Moreover, idle servers consume between 60% and 66% of the peak load power consumption. The study explores most of the previous load balancing techniques which are used to enhancing the cloud performance and reducing the power consumption in a cloud data center with the illustration and analysis of these techniques' shortcoming. It has been stated that all of the previous load balancing techniques focus on enhancing the response time, availability and QOS and ignore the negative impact of increasing power consumption on the surrounding environment.
In order to achieve the objectives of this research and due to the nature of the study, the study used a combination of quantitate and qualitative methods, we opt to employ cloud based E-learning model, where the new CPLB model is being constructed and evaluated, we find it useful to employ the modeling and experimental methodology, because such methodology enables us to describe the proposed system model and further validate it through experiment processes, where it becomes possible to compare and analysis results between the current and proposed model.Supervised by: Assoc.
