In spite of employment practices in recent times, students are progressively taking up projects to pad up their skill-set. Engineering projects help students to learn and acquire practical knowledge. Despite of theory concept they acquire, various industries also need to know their capacity to complete projects using their specific initiatives. Thus, we recommend students to realize engineering projects in their four years of engineering and try to present as many white papers as possible. Students who give importance to their course projects are expected to learn how to: ● Work in teams including multidisciplinary teams Build a major design experience based on the knowledge and skills acquired in the course work Build a major design experience incorporates appropriate engineering standards and multiple realistic constraints Apply both analysis and synthesis in the engineering design process, resulting in designs that meet the desired needs In the design process, both creativity and criticism are essential. The followings are the seven steps that students should consider while designing their projects: Recognition of the need and identifying opportunities: Every project begins with recognition that needs improvement. These needs may be obvious or hidden to be revealed by investigation, surveys or research. Definition of the design problem: It is a major task requires gathering information about the problem. Definition of the design criteria and constraints: While the problem is being defined, the design criteria and constraints must be defined a. Design criteria are performance standards to be met by the design b. Design constraints are limitations placed on the designer, the final design or manufacturing process. Examples of possible constraints include accessibility, aesthetics, codes, constructability, cost, ergonomics, extensibility, functionality, interoperability, legal considerations, maintainability, manufacturability, marketability, policy, regulations, schedule, standards, sustainability, or usability. c. Risk analysis The design loop: design is a repetitive process of: a. Synthesis (Brainstorming - Generating new ideas) b. Analysis (Breaking ideas - find expected results) c. Decision-making (Deciding the best alternative) Optimization: Design team must ask themselves if it is the optimum design. Optimum is the best design that can be achieved at reasonable cost. The proposed design is judged against the design criteria Evaluation: Design team should hold a design review to approve drawings and specifications before they are released. If an optimum design cannot be achieved, the design team might revise the problem definition, the design criteria or the constraints in order to achieve the optimal solution or prototype. II. Project Description Digital signal processing has many real-life applications in. Students can choose one of the following suggested projects for their course project. Student must develop the design to the prototype mainly in his own time, however, some of the office hours and lab times will be set aside to enable you to seek clarification, get more details from your instructors, and receive feedback on your work. The developed system should have the following: The project MUST have a working prototype. The projects should employ, if appropriate, artificial intelligence such as deep learning algorithms to identify/authenticate users. Hardware implementation using Raspberry pi, Arduino or any microcontroller, and any other necessary components related to the selected project. Software part of the project will be developed using Python/SciLab/ MATLAB or any other programming language. Do not diverge from the project specification. If you do not conform to the project specification, you will lose a high share of the project grade. C. d. 1- Activity detection using wearables You have been hired by a company that manufactures wearable motion sensors for activity recognition, particularly tailored to assisting the elderly and recognising unusual behaviour. A wearables sensor unit commonly consists of accelerometers, gyroscopes and magnetometers, which, in combination, can measure an individual's motion. Recently the company has been interested in building wearables systems. You have been assigned the job of designing and implementing a robust wearables sensor unit that can provide tri-axial data from an accelerometer and a gyroscope. The developed prototype should address the following points: a. Construct a simple wearables sensor unit with an accelerometer and a gyroscope b. The sensed motion shall be categorised as one of four activities via a microprocessor Four different activities shall be detected and displayed on a simple display unit All circuit design details should be provided in the project report. 2- Stepper motor control You have been hired by a company that manufactures controllable DC motor systems. Recently the company has been interested in designing a range of highly controllable DC stepper motors, for use in laboratory environments. You have been assigned the job of designing and implementing a PID- controlled stepper motor system. The developed prototype should address the following points: a. A DC stepper motor shall be utilised to adjust the angular position of pointer object |||. b. Precise control of the stepper motor shall be achieved using a microprocessor-based PID controller C. d. A pot (potentiometer) shall be used to implement the desired angular setting All circuit design details should be provided in the project report. 3- Object Sorting by Colour You have been hired by a company that manufactures components having various colours. You have been assigned the job of designing and implementing an object sorting system that separates balls based on their colour. The developed prototype should address the following points: a. The coloured balls shall be contained in a cone-shaped bowl that dispenses the balls b. There shall be at least 6 differently coloured balls C. A microprocessor and appropriate sensor shall be utilised to categorise the various balls d. All circuit design details should be provided in the project report. 4- Silhouette Detection System You have been hired by a company that provide computer-vision solutions that use image processing to recognise and categorise image data. You have been assigned the job of designing and implementing a system for identifying different silhouettes, which emulate the shapes often encountered when using low-tech, low-resolution cameras for high-altitude reconnaissance tasks. The developed prototype should address the following points: a. The system shall successfully identify 6 or more greyscale or black-and-white silhouettes b. A database of allowable silhouettes will be supplied by your instructor C. A microprocessor and appropriate sensor shall be utilised to categorise the various shapes d. All circuit design details should be provided in the project report. ABET Learning Outcome The aim of this project is to make the students, who manage to fulfill the project requirements, have: i. The ability to identify, formulate, and solve complex engineering problems by applying linear transforms, and linear algebra. [1] ii. The ability to apply engineering design process steps to produce solutions that meet specified needs with consideration of public health, safety, and welfare, as well as global, cultural, social, environmental, and economic factors. [2] iii. The ability to communicate effectively with the audiences of his/her design. [3] iv. The ability to work in teams, create a collaborative and inclusive environment. [5]
