Energy generation using palm waste for Heating applications, case study for Palestine.
(2024-03-12) Ahmad Abuarra; Dirar Hara; Firas Mnasour
Abstract
Date palm trees, especially Alhayani, Barhi, and Majhool, have a rich history in Palestine.
However, the waste produced by these trees, such as unripe dates, date pits, and palm fronds,
is usually burned on farms, leading to environmental concerns, or collected them inside the
farms for long periods, which leads to the emergence of the red date palm weevil, which works
to damage palm trees.These wastes are a significant source of excellent biomass that can be
used in many applications such as energy production, livestock feed, fertilizer for soil, and
wooden boards, and can even be used as insulating materials. This project focuses on utilizing
agricultural waste from date palm trees in Palestine by grinding and transforming it into
wooden blocks for use in heating, bakery ovens, household wood stoves, and other
applications. The effectiveness of these waste materials for use as excellent heat value
resources has been demonstrated, especially when compared to other tree waste. The heating
values for date kernel (17.1267 MJ/Kg), palm leaf (16.8873 MJ/Kg), and palm frond petiole
(15.9897 MJ/Kg) indicate their promising potential for use in heating applications. A feasibility
study was conducted for a production line that converts these waste materials into wooden
blocks for use in heating applications. The annual profits were estimated at approximately
150,240 NIS, with a payback period of around 2.4 years and a return-on-investment rate of
36.3%

AutoPizza
(2023) Shahd Bilal Hamza; Fana Abdul Rahim Yamk
In response to the increasing demand for convenient and personalized food options,
particularly in the case of pizza as a popular fast food choice, our idea is to develop a
user-friendly and customizable pizza station. By leveraging technology, our pizza station
aims to simplify and automate the pizza-making process, making it faster and more
accurate. Whether it's for special events or quick hunger cravings since traditional methods
often fall short in terms of speed and customization. Our pizza station presents a
straightforward solution to the issue of limited options. Its user-friendly interface allows
customers to customize their pizzas effortlessly based on their preferences. Moreover, our
station boasts a reasonable size that allows for easy placement in various settings, without
occupying excessive space like those found in factories
Our pizza station takes a step-by-step approach to pizza-making. The process starts with
the use of pre-prepared dough or bread, sourced externally. Once the user specifies their
desired pizza options, the pizza goes through different stations tailored to their selections.
Finally, it enters the oven and emerges as a delicious, ready-to-eat pie, and notifies the user
for it . Our station is carefully designed to minimize waste by efficiently using the
necessary ingredients and preserving excess components for future use. This approach not
only optimizes the pizza-making process but also aligns with our commitment to
environmentally conscious practices. To ensure uninterrupted operations, the machine is
equipped with a component tracking system that monitors the availability of ingredients.
When a specific component runs out, the system automatically sends a notification to the
administrator, prompting them to refill the depleted item. This feature ensures a continuous
supply of ingredients for pizza production.

fani
(2023) Fana Abdul Rahim Yamk; Shahd Bilal Hamza
We often need help finding maintenance technicians, which can be due to a scarcity of
technicians in certain areas, their unreliable attendance for crucial appointments, or
uncertainty about their skills. These problems are even more significant for women. An
application that addresses all these issues and offers several benefits for both users and
technicians is the solution. The application streamlines communication between regular
users and registered technicians, enabling users to choose the maintenance they need, view
available technicians, and pick their preferred technician based on factors like chat,
notifications, and feedback. the user can sign up as a regular user with basic information or
as a technician with additional information such as profession, age, experience, and work
location. The program features a maintenance services page that covers cleaning, electrical,
electronics, and other services, and can be detailed based on the type of service. The admin
controls this page through a web page that lists all registered users and technicians.This
type of application has begun to emerge as technology infiltrates all aspects of life. Still,
there are not enough services available yet, and it has not been implemented in Palestine.
We choose to use the Flutter platform for the front end because it has many libraries and is
compatible with various operating systems, and for the back end, we will use Node.js it
supports real-time communication and we are already familiar with it.

Mr.Fix it
(2024) Sundos Mustafa Saifi; Abdullah Munther Refai
We all face some problems in our homes and need a lot of services from handymen. We may face difficulty in finding those who have sufficient competence and experience. Therefore, in this project, we decided to create an application that brings together all these workers with their various services in one place, to make it easier for users to find what they need in the shortest time and best choices.
In order to solve this problem, we’re going to implement a mobile application which manages the handymen and the clients who need them to solve some issue.
The system consists of two types of users:
the client which can access the main dashboard which displays the top-rated workers, featured ones, others list which displays mix of new handymen and the oldest ones, and some ads ,Discover dashboard in which you can browse the workers, see their profiles, rate and some additional info, from this dashboard you can contact with the worker that you want and request a task from him, Chat dashboard which contains all the chats that the user made with the workers, and he can send messages and receive ones, Post a task dashboard which allows the user to post one of two types of tasks the first one is the normal task in which he includes the details and the price he can pay for this task and the second type is tender in this type each handyman can see the details and assign a price for this task and the user choose the best offer for the client, these tasks will appear in a specific dashboard in the workers app but it will be based on the requested type for example if the client requests a task looking for a plumber, this will appear only in the plumbers accounts not in the other types, Profile dashboard which allows to edit his information, there is search bar to find workers, Donation dashboard, which the user can donate some funds to the application owners if he enjoyed the service, and assigned tasks dashboard in which he can see his tasks that workers are working on.

Claw Machine
(2023) Sundos Mustafa Saifi; Abdullah Munther Refai
A claw machine is an enjoyable type of vending machines, it can be found in arcade
shops, malls and movie theatres, this machine could be considered as a challenge
versus time, in this game a person can control how many minutes he wants to play
and he wins the items he gripes in that specified time. This machine gives the player
the opportunity to play in one of these options, the first one is using joystick While
the second one is from mobile phone application and at last using hand gestures
through camera and image processing. This machine is divided into four parts:
control, logic control, mechanics and playing area. The logic control consists of
Arduino mega as a main controller, five HY-DIV268N-5A motor drivers, ESP8266
for mobile control, orange pi for LTS (single board computer) for hand gestures
control, Arduino Uno, SD card module for storing sounds, and power supply for the
system. Control part consists of lcd for displaying game instructions and remaining
play time, joystick to control the gripper position before gripping item, keypad to
specify the time and choose the game control mode (1: joystick, 2: mobile
application, 3: hand gestures using camera), RFID for payment and start/catch
button. The mechanics part consists of gripper that carried by motor and rope which
this motor can be moved through (x, y) plane and the gripper that tied with rope is
the z axis, one stepper motors for x movement, two stepper motors for y movement,
one stepper for z movement and the last stepper for the gripper, stainless steel rods.
The playing area contains the items that the player can grip, speakers for sounds and
RGB led strips.
