3 Axis CNC MILLING MACHINE
(2013) Ahmad M. Shayeb; Ahmad W. Odeh; Otrah Y. Al-Husseini; Shadi B. Hantouli; Bashir M.Y NOURI
The machining or cutting of metals portion of manufacturing became important around thetime of the industrial revolution. In 1775, John Wilkinson invented a cannon-boringmachine (lathe) in England .He adapted that machine for boring the cylinders forBoulton & Watt's steam engines. His boring process was the only one of its kind to producethe smooth, tightly tolerance bores required of the cylinder of a steam engine.A bit later in the year 1818 Eli Whitney (inventor of the cotton gin) invented a millingmachine in New Haven Connecticut .Prior to the milling machine, a machinist's toolswere primarily files and required a highly skilled operator. The milling machine allowed aless skilled operator to make the same quality of parts as the skilled operator with the file.The spindle of Eli Whitney's milling machine was moved from being horizontal to beingvertical. This is commonly seen in the Bridgeport style knee-mill.In year 1952 John Parsons invented NC (Numeric Control) milling machine. Parsonsworked to attach servomotors to the x and y axis controlling them with a computer thatreads punch cards to give it positioning instructions .The reason for devising such asystem was to machine complex shapes like arcs that can be made into airfoils forairplanes.Today, modern machinery are CNC (Computer Numeric Control) milling machines andlathes. A microprocessor in each machine reads the G-Code program that the user createsand performs the programmed operations. Personal Computers are used to design the partsand are also used to write programs by either manual typing of G-Code or using CAM(Computer Aided Manufacturing) software that outputs G-Code from the users input ofcutters and tool path . CNC can be classified according work as lathes, milling machines,laser cutters and other industrial tools. The CNC term refers to a large group of thesemachines that utilize computer logic to control movements and perform themetalworking[2].Lathes are designed for the precise machining of relative hard materials. These rigidmachine tools remove material from a rotating work piece via the (typically linear)movements of various cutting tools, such as tool bits and drill bits.Rotating is the way that lathe shapes the material and with a rapid speed, this is done bypressing a fixed cutting or abrading tool. Now a days, lathes equipped with the CNC to helpfashion tool and products.The machine is controlled electronically via a computer menu style interface, the programmay be modified and displayed at the machine, along with a simulated view of the process.The operator needs a high level of skill to perform the process, however the knowledgebase is broader compared to the older production machines where intimate knowledge ofeach machine was considered essential. These machines are often set and operated by thesame person, where the operator will supervise a small number of machines (cell)[3].Milling is the process of cutting away material by feeding a workpiece past a rotatingmultiple tooth cutter. The cutting action of the many teeth around the milling cutterprovides a fast method of machining. Milling machines are classified to, peripheral milling,Another classification of milling according to the movement is the vertical and horizontalmilling. In the vertical mill, the spindle axis is vertically oriented. The horizontal mill hasthe same sort of xy table, but the cutters are mounted on a horizontal arbor across thetable[4].All CNC machine types share this commonality: They all have two or more programmabledirections of motion called axes. An axis of motion can be linear (along a straight line) orrotary (along a circular path). One of the first specifications that implies a CNC machine'scomplexity is how many axes it has. Generally, the more axes, the more complex the machine .

A Comparative Simulation between Monofacial and Bifacial PV Modules under Different Conditions
(2023-06-11) Mahmoud Kobari; Ahmad Mallak; Ahmad Titi
Abstract During the last period, solar energy gained a lot of attraction and is expected to be the replacement for non-renewable energy due to its great potential and advantages, one of these advantages is that solar energy is scalable, this means it can be used on an industrial scale or lesser, another advantage is that solar energy is a clean source, this means it causes no pollution to the environment, in addition solar energy is the future, as its cost is going down and non-renewable energy is becoming more and more expensive. This project aims to conduct a comparative analysis of the performance of bifacial and monofacial solar panels under diverse conditions. The investigation involves examining the influence of varying albedo levels and the type of surface beneath the PV panels, including sand, white paint, black asphalt, or artificial grass. The renowned software tool PVsyst will be employed to simulate and analyze PV systems. The location selected for this study is An-Najah National University in Nablus, Palestine. The PV panels will be oriented towards true south, and a tilt angle of 28˚ will be employed. Through meticulous simulations and thorough analysis, this research seeks to provide comprehensive insights into the contrasting performance characteristics of bifacial and monofacial solar panels across different environmental contexts. The ultimate objective is to contribute valuable knowledge regarding the suitability and optimal utilization of these PV technologies. The study aims to evaluate and compare the electrical output, energy yield, and overall performance of bifacial and monofacial solar panels under different scenarios. The project will analyze factors such as the energy gain achieved by the bifacial panels due to rear-side irradiance reflection, the impact of albedo on the performance of bifacial panels, and the influence of shading on both panel types.

A Revolutionizing Packaging Machine for Identical Mixes within the Packages: Case-of-Study for Ezz Al-Maslamani
(2023-06-08) Al-Montaser BeAllah Al-Maslamani; Wadah Qartallo; Abdul Fatah Shehadeh; m.abuabiah@najah.edu
t Food manufacturing companies have a flaw that is concealed; unequal distribution of the ingredients in their packaging line. This problem results in packages with different proportions instead of the identical bags intended made. Such big manufacturers tackle such an issue with marketing, for example, “enjoy an odd mix.” Still, this affects customer satisfaction which affects their profit as well. This issue happens especially when the container of a product is seethrough, customers have been noticed to be picky about the mix inside. Therefore, this project aims to develop and construct a machine that should solve this phenomenon. The machine will use helical actuators that pour the required proportions of each product simultaneously into a weight head. This will ensure the bags are as identical as possible with a minimum error rate. The proposed machine could be adopted by industries in the mechatronics and packaging industries. Yet, now the funder is a local company named Ezz Al-Maslamani Company. This project will be divided into two phases: the first is designing the machine as well as doing all the calculations necessary for the work environment, while the second phase is validating the machine in Ezz Al-Maslamani Company and running it. The main objectives of this project are summarized as follows: • Design a machine that will ensure an identical mix in packages. This will be done using SolidWorks as well as Factory I/O to test and simulate the PLC. • Customer satisfaction: It has been observed that customers are picky about see-through packages depending on which ingredients they like the most. This machine will ensure everyone has the same mix every time. • Gain ISO 9001 for the company: 9000 family means there is a standard within the production as well as other things. This project will ensure standard mixes along the packages, thus moving the company closer to an ISO certificate. The previously mentioned objective will be accomplished using the following components: the machine that will be constructed contains mechanical and electrical components. The mechanical components will include actuators such as helical screw conveyors, pneumatic systems, and silos for the products that will be mixed. On the other hand, the electrical parts will include a PLC integrated into an HMI and motors. The electronics used will be sensors and a weighted head. Due to various reasons, the project has transitioned into a prototype stage due to several distinguished engineers recommending this course of action, given the inherent uncertainty surrounding the mechanism. In this prototype, three Arduino units were utilized as a substitute for the PLC. Additionally, MATLAB’s App Designer was employed instead of a traditional HMI. 2

(2023-06-19) Othman Shuqqo; Rafeeq Tanbour; Samer Qamhiyeh
Abstract The spiking numbers of the population that are being seen in the recent years have led to continuous overcrowding of public places, which made these places venerable to waste dumping on daily basis, many solutions are applied to control and manage the waste problems, and this project is one of them. This project is a small-scale road cleaning machine that aims to reduce dust and waste in narrow roads, public parks, university campuses, and other tight places where cleaning vehicles can’t reach. It sweeps and vacuums the road or pavement while it’s being driven at low speeds. In this research, the study was made to find out the advantages of this project which are: small size, high efficiency, and providing the greatest amount of public hygiene while the pollution is increasing on the planet. At the same time, a study of the ability to create it under the available capabilities and the current circumstances had been caried out. This project was originally intended to be a complete restoration of a mid-size abandoned cleaning vehicle, that was abandoned for over 20 years, but after intense studying of this case, and after going on multiple site tours to the works department facilities of Nablus municipality, and after learning from the engineers in the field, it had been realized that this idea can be hard achieved under the current circumstances, mainly due to financial reasons, and all the complications that come with working on such large machines, therefore, the team for this project opted for another design of a system that could help achieve the desired results using available resources at the lowest price possible.

Aerodynamic Bump
(2014) Amr Malhis; Shadi Qazza; Odai Amira; Omar Abu Ghdaib; Ramez Ibrahim Mohammad Abdallah
Abstract:Invent a new way to generate electricity "Aerodynamic Bump" For ages and for multiple reasons, especially the lack of energy sources in Palestine and the dominance of Israel over the energy sources. Palestine faces serious issues of using energy sources that make us have a need to find new way to generate electricity through renewable energy sources The concept of this project is an aerodynamic bump that generate electricity through comprising air in a closed system, then the compressed air runs the turbine, when the air pass through it then after the electricity had been generated, it will store in stationary batteries This project is the first of kind in the world, but there is similar application that used to generate electricity like speed bump power generating system and speed bump pave the way to alternative energy The main three points to be achieved in this project 1- Find a new way to consume the renewable energy effectively2- Reduce the cost of electricity due to the cost of the electricity is high 3- Amount of power generated. To achieve the first point which is finding new way to consume the renewable energy we invent the aerodynamic bump that made the function that we looking for. The second point is concentrated on reducing the cost of electricity due to the electricity in Palestine is purchased from Israeli's market which is considered high respectively with other countries The third point which is considered the main point of this project is the amount of the power generated, because we seek for a large amount as possible as we can to produce.Description Of the system: When the vehicle cross over the bump the board metal plate presses up the bump down in order to pressure on flexible pipes filled with air and inside these pipes there are springs to keep the bump standing, Air rushes by the metal plate in order to pressure pumped through pipes connected to the main pipe congregate in which compressed air and air to arrive Wells turbine which continues to rotate in the same direction by the air pressure. The Impeller (Wells Turbine) rotates to drive an electric generator. We can use toothed wheels or gears to reach between the turbine and generator are organizing the turbine rotation speed equal to the rotation speed and regular. Electricity generator generates a continuous electrical current DC or AC depending on the type of generator used and regulated energy generated by an electricity transformer and sends power to the electricity grid or stored in stationary batteries. The springs inside bumps raising the ceiling bump so that expands after crossing the vehicle and so pulls the air again into bump to reflect the air again through the Wells turbine but in the opposite direction and because of this property that turbine continues to rotate in the same direction with the change of direction of air, and then be the bump ready to receive another vehicle to repeat the cycle.Objectives of Project: The objectives of this project are:1. Investigate the Aerodynamic bump systems and applications.2. To utilize the exists of the bumps on roads to generate electricity.3. Design and construct aerodynamic bump systems that produce electricity without any cost depending on the air-flow principals.

The objectives of this project are: obtaining the skills to design an aerodynamic system for a formula one car and learn to use the computational fluid dynamics(CFD) software. Formula one car is a single-seat open cockpit, open-wheel racing car with substantial front and rear wings, with an engine positioned behind the driver, intended to be used in the competition at Formula one racing event. In this project the team will work on fabricating, designing, testing and demonstrating a prototype vehicle with a high performance. The goal of this project is to create highly efficient aerodynamic devices that will make the car operate properly and efficiently on the race track at the Formula society of automotive engineers(FSAE) competition. It will be a great chance to compete with teams all around the world and develop a vehicle that can successfully work as described in the FSAE rules. The benefits of this project are: gaining knowledge, experience in vehicle design, ideas for overcoming future hardships and develop our thinking skills, practicing and improving the team working skills, gaining project management skills, obtaining construction and manufacturing experience, competing in an international setting, increasing student future opportunities in finding promising jobs. This team is mainly responsible for studying of air flow around the car and its interactions with the racecar, the aerodynamics of the car (e.g. the front and rear airfoils). The final project should have very high performance in terms of acceleration, braking, handling and to be sufficiently durable. This team is in charge of the aerodynamics of the race car. The two primary concerns are: the creation of down force to help push the car's tires onto the track and improve cornering forces, and the minimization of drag and lift forces. Those forces are products of air resistance, which acts to slow the car down. The front and rear inverted airfoils or wings have a major influence on the dynamic behavior of the car. These wings are designed in order to develop a maximum down force at still acceptable drag. Full car CFD simulations with the analysis of forces on the race car are required, detailed quantitative analysis of the forces on the whole car with and without aerodynamic will be shown and compared. This thesis describes the process of developing the aerodynamics package of a Formula Student race car with computational fluid dynamics. It investigates the effects of aerodynamics on the vehicle's behavior and performance with regard to the Formula Student competition format. The methods used during the development are evaluated and put into context by investigating the correlation between a wind-tunnel experiment of a wing in ground proximity, and its simulated counterpart. The aerodynamics package consists of an under tray, a front wing and a rear wing and the report details the stages involved in optimizing these components to achieve the desired results.
Agricultural robot

Agriculture is the largest sector in the Palestinian economy, so the idea of our project will be in this part. After a deep research, it was found that the agricultural sector lacks the minimum comfort components that save effort and time for Palestinian farmers. Smart farming methods have evolved rapidly in recent years due to their importance in saving time, effort and ease of use in any agricultural facility. However, there is no manufacturing in Palestine, only import. This project will propose the first model of the smart agricultural system in Palestine, which should contain the basic elements of any agricultural system, and then develop it into a model that meets the market needs. Relying on control principles, electronics, microcontrollers, various programming types of hardware and software, power systems, and built-in knowledge of engineering to provide a business model ready for manufacturing. Among the processes will be multiple steps such as handling low power systems then mechanical control and compatibility of the system for optimum operation and setting the basics to obtain the best product for the application. As far as noted, there is no any similar idea to this on the ground in the facilities. But simple conventional farming systems are flooding the markets required for every facility and can be combined with access control systems that indicate their importance locally or globally. In general, the main output of this project will be a smart agricultural system that can be versatile and easy to apply and use in the field for which it is designed.

An experimental investigation of the impact of the dust deposition on the performance of the PV systems at different tilt angles in Palestine conditions. ___________________________________________________
(2023-06-18) Mohammad Ahmad “Ali Khader; Karam Ali; Khalil Daraghmeh; Abdullah Mansour
Abstract: There are a lot of factors that can affect the solar energy that PV panels harvest one of the main factors is the soiling effect. The performance loss occur because the dust particles block the sun rays from getting in the PV cells therefore less power generated. The more the tilt angle is increased the harder the dust particles get sticky on the PV panel’s surface due the gravity pull them down. The objective of this study is to see whether increasing the tilt angle and how much will affect the soiling effect, PV panels will be set on tilt angles of (0,15,30 and 45) degrees, The soiling effect will be calculated by measuring the difference between the power generated by the cleaned and uncleaned PV panels on same time. The study had calculations of the soiling effect on different scenarios Monthly, each two weeks and weekly for Monthly average it has found that tilt angle of 45 the soiling affect has become low 2.53% on tilt angle of 30 has become 6.33% on tilt angle of 15 has reached 7.94% on tilt angle of 0 has become 10.20%.Also the study has recorded a spike in Khamasinee winds which is known that it causes high soiling effect as it caused the soiling loss of tilt angle of 0 spikes from 18.89% to 20.59%, tilt angle of 15 from 16.52% to 20.59%, tilt angle of 30 from 16.52% to 18.89% and tilt angle of 45 from 3.53% to 8.11% as daily readings for each one. The study has concluded the more tilt angle is increased the more soiling effect goes down also it has founded that the first half of May month and the last week of April do not cause huge soiling as it was founded in results but the second half of May were soiling effect tends to be a concern.
ANALYSIS OF UPGRADING DIESEL ENGINE BY MEANS OF TURBOCHARGER
(2018) Saleh, Saleem; Diyaa, Atatri; Ramadan, sawafta; Khalid, khabbas; Luqman, Herzallah
This project has choose because no one has ever submitted a previous research on it in our university, until we take advantage of the old cars to keep up with the modern cars. The purpose of this project is to increase engine power, efficiency for diesel engine, decrease gas emissions and reduce the consumption of fuel. So by our project we can improve this properties. All of this adjustment will be done by using turbochargers so we will design theoretically the appropriate turbocharger for the diesel engine, so the aim of our project is to make old cars able to keep pace with the development of modern cars in terms of performance. The turbocharger, a compressor – turbine combination, uses the energy available in the engine exhaust stream to achieve compression of the intake flow. So to design the appropriate turbocharger we will focus on the thermal analysis, dynamics and fluid analysis. We will use a diesel engine from one of the heat laboratory experiments because we have all the necessary information about it and there is no turbo with it. We have not been able to design it in practice due to the lack of equipment and the necessary materials, in addition to the lack of financial support for the project. A blade design of the turbomachines is one of the important steps for a good turbomachine design. A blade design process not only directly influences the overall machine efficiency but also dramatically impact the design time and cost. In this study, a blade design and optimization procedure was proposed for both turbine and compressor blade design. A compressor blade design was used as a test case. It was shown that the current design process had more advantages than conventional design methodology Applying the theory of turbo machinery to increase the power and efficiency of the engine is used these days in the new cars, but the project focus upgrading the old cars, which is not common today.
Assessment and Potential of using Passivated Emitter and rear cell (PERC) in Palestine
(2023) BelalBazari; Eng. Bahaa Jadallah
Energy sources in the Palestinian territories are very limited and depend on importing different types of fuel from neighboring countries, And the Israeli occupation, therefor is a need for renewable energy such as solar energy. Solar energy is one of the most important sources of clean renewable energy at present, which contributes to saving money and effort. Solar energy is absorbed and collected by solar panels. Several types of solar panels are currently available, and solar panels are constantly being developed to obtain maximum solar energy, reduced maintenance, and a longer endurance period. PERC has a global influence on both power generation and greenhouse gas emissions reduction since photovoltaic (PV) is on pace to become the dominant power generation technology. PV Green House Gases reduction will reach roughly 5% in 2022, including 2% of PERCs, assuming a 25% annual growth rate of PV installations. The main objective of this work is to experimentally investigate the behavior of the PERC unit and compare it with the performance of the POLY unit under the influence of the Palestinian climate. The temperature of the two solar panels differed, and that of PERC was lower than that of POLY, due to the fact that the PERC panel has a heat-reflecting layer and thus increasing the efficiency of the PERC panel. The efficiency of the panels was calculated at the same value of solar radiation, where it was found that the efficiency of PERC is higher at the same value of solar radiation, in fact, the solar radiation absorbed in the PERC panel is greater because of the reflective layer that enables the PERC cell to benefit from the solar radiation as much as possible and, with the increase in radiation solar energy, the energy produced increases. PERC panels produced more power per unit area than the poly panel

The water shortages is expected in this region requires us to search for new sources of fresh water either be from atmospheric air or by water desalination but the use of Desalination Technology requires a water source salty and need a high cost, but for the extraction of fresh water from atmospheric air it can be applied anywhere on the surface of the earth has the moisture, and has been proven that the atmosphere is huge and renewable source of water, and that this source is not expensive and also helps to reduce the proportion of moisture. In this sense, our project is based on the design of a device that is to absorb moisture from the atmosphere to extract pure water drinkable; this device also helps to reduce the percentage of moisture in the air which constitutes an obstacle to most people. The working principle of this device is the absorption and intake air through the holes, and then passes the air on a candidate runs on clean of dust and harmful substances, after which it is to intensify the air, making it water, then passes several operations of filtering and cooling to become pure cold water and drinkable. In this project many topics will be covered starting of how this device works, main components, then we will explain how to design the device and materials needed to manufacture it, and how to connect to each other, which will help to bring to reality, and finally we will study how to operate the device either through electricity or through sources of energy (sun, air, fuel, etc.). Also note that this project has been studied before, is been known for a long time, but after the resistant and chronicle of the water problem, increased focus, and the payment of German engineer Hubert to discover how the design of this device, and then establish a private company so named (Aqua Society).. And who designed the device also is a Canadian Jonathan Ritchie, where he designed device called watermill.
atmospheric water generator

An atmospheric water generator (AWG) is a device that extracts water from humid ambient air. Water vapour in the air is condensed by cooling the air below its dew point, exposing the air to desiccants, or pressurizing the air. Unlike a dehumidifier, an AWG is designed to render the water potable. AWGs are useful where pure drinking water is difficult or impossible to obtain, because there is almost always a small amount of water in the air. The two primary techniques in use are cooling and desiccants. [1] The extraction of atmospheric water may not be completely free of cost, because significant input of energy is required to drive some AWG processes, sometimes called "trading oil for water". Certain traditional AWG methods are completely passive, relying on natural temperature changes, and requiring no external energy source. Research has also developed AWG technologies to produce useful yields of water at a reduced (but non-zero) energy cost.
Auto Tire Inflation System (ATIS)
(2021) Khailaa Mashaqi; Sawsan Abuamara
Wheels are one of the most important part of vehicles and they are permanently vulnerable to changes to cope with the new technologies and enhances both on manufacturing technique and the materials that are used. One of the primary concerns of the wheels is maintaining air pressure of the tires to guarantee passengers comfort and car efficiency that can affect fuel consumption as well as the dynamic behavior of a vehicle. Furthermore, losing pressure on tires can cause a danger on the passengers as the car may become unbalanced on the street and also can harm the wheel rim when the tire falls down. Therefore, maintaining tire inflation pressure automatically, without the need for human intervention, is becoming a hot topic these days. Thus, this project aims to design an auto tire inflating system (ATIS) that can check the tire inflation pressure, compare it to a target value and manage inflation and deflation actions to realize and maintain the target inflation pressure. The proposed system will be applicable for all vehicles of classes B and C without any change in the vehicle component and/or structure. The main objectives of this project are the following: • To help drivers guarantee a suitable pressure, over a narrow tolerance range, without the need to change the puncher wheel; especially in the event where they are far away from gas stations/Mechanical workshop, as well as saving time and effort on the driver. • To present a specifically developed solution for the utilization of an auto tire inflating system in a passenger vehicle and to automatically manage tire pressure through inflation and deflation actuation. On the other hand, in this project, we will solve several challenges that occur in ATIS systems, such as connect air of pump to the wheel. Finally, all the challenges in electrical conductivity and the amount of air coming out of the pump will be discussed and analyzed in details.
Auto Traking Solar System
(2007) Bader Sharaf; Hasan Osta; Hani Sadder; Bashir M.Y NOURI
Palestine is considered a poor country in the sources of fossil fuel (power), nowadays this fossil power prices are escalating to unprecedented levels, which is not affordable by our economy especially that the demand on this type of power is increasing, in other words the prices of oil is expected to go higher & higher.. which our citizens can not withstand , As long as Palestine is a sunny country, the most suitable solution for our poverty in fossil fuel is to look for the means that allow us to utilize the free power of the sun. Upon the studies conducted on solar power it is noticed how huge is the quantity of unutilized solar power, as a result of our negligence to this vital & free source of power. Compared to the other projects which were built to utilize the solar power, our project is:- 1. Applicable: it is easy to manufacture, the raw material used to fabricate it isavailable & it needs no operators. 2. Efficient: the incident rays of the sun remain perpendicular on the plate (panel) all the day over, which actually means that the output power is the highest attained. 3. Low running cost: because the operation cost is merely negligible. For the above mentioned justifications we believe that our project is practical & cheap. We hope that the university will adopt it one of the leading projects that its students have created.

Because of the booming fast food and restaurant industry in Palestine, butchers are seeing an increase in demand for burgers in particular. The manual force makes around 100 burgers per hour with low quality, varying weight, and low precision, but the machine produces about 500- 2000 burgers per hour with high accuracy and weight, and there is also a significant cost for importing such burger making machine from other countries such as China, Germany, and Turkey. Manufacturing such a machine domestically will be far less expensive and easier to maintain in the Future. In order to satisfy the needs of the local market for such machines, a model of an affordable burger-making machine is designed and fabricated in this project, the model was produced for the benefit of a local Butchery shop in Qalqilya city called (The butchery of Qalqilya), who provided the financial support under ABET agreement template. In this project, the design and manufacturing of the Automatic Burger Machine was completed, several problems were overcome, and the market was researched in West Bank cities, including butcheries and restaurants because they are the main targets customers. Solidworks program was used in the conceptual design then it was also used for the final Design for Manufacturing model. The Design of the final model was completed and delivered to a local manufacturing company (National manufacturing Company) to fabricate the machine under an agreement signed by the beneficiary (Butchery of Qalqilya) and the manufacturer; the agreement gave the project team the permeation to participate in the manufacturing process, and assembly of the control system for the machine. The obtained machine is able to produce high quality packed burger pieces with an adjustable production rate varying from 300-1000 piece per hour. The machine is standardized to give 100g burger with 13cm diameter and 8mm thickness, this standard size can be easily customized by changing the moulds size
