3. Guidance

The Program has eight full-time engineers dedicated to laboratories who provide the students with appropriate guidance regarding the use of the tools, equipment, computing resources, and laboratories. In addition, the demonstrators (usually graduated students with excellent GPA) in the program participate in the mentioned guidance process during their staying period before getting an admission to continue their graduate studies mostly abroad. The faculty members of the Program participate effectively in guiding the students for safe use of equipment and laboratories. Their roles are very important through directly monitoring the performance of the engineers and technicians during laboratory hours. They make sure about the safety issues by running the first set of experiments after the installations of new equipment.

Safety issues are routinely addressed by delivering lectures to the students on first day of the laboratory and thereafter are monitoring and strictly enforcing the do's and don'ts on the students. Also, it should be indicated here that each lab is equipped with a first-aid kit, lab safety manual and general safety instructions printed on a large-scale notice board. This is in addition to signs showing the lab title and the exit emergency doors. Safety glasses and ear protectors are available as appropriate.  Fire protection is insured through the centrally installed fire alarm and fire extinguishing water systems as well as CO₂ movable fire extinguishers. The Departmental lab committee, Faculty of Engineering Facilities Unit and the University General Administration for Security and Safety run periodic auditing of safety in laboratories and report findings to the head of the department.

Guidance in Instructional Laboratories

Instructional laboratories are essentially attached to specific courses. For this reason, course instructors are responsible for the general supervision of the experiments done in these labs. Every laboratory is also assigned an engineer responsible for maintaining the lab and guiding the students during their lab session. In particular, the lab engineer will:

§  Instruct the students on lab safety

§  Explain how the experiment is to be conducted and distribute any required lab experiment sheets

§  Help the students in doing the actual experiment

§  Collect and grade lab reports under the supervision of the course instructor

§  Prepare a lab binder

Guidance in Computer laboratories

The teaching assistants are responsible for:

§  Helping the instructor during and after the lecture

§  Supervising the tutorial sessions

§  Maintaining the PCs by updating the hardware and the software

Guidance in Engineering Workshops

The instructor of the specific course making use of the workshop is responsible for the conduct of the experiments related to his course. One of the technicians serves as a general supervisor of the workshop. The workshop technicians are also responsible for helping the students in their workshop assignments, and any manufacturing related to their senior project.

The faculty policy is to devote the first lecture in the workshop to safety. Students are required to bring their own gloves, safety goggles, ear protectors, work jackets and boots. They are not allowed to enter the workshop without wearing them. This is strictly enforced by the workshop supervisor and the attending technician. The workshop supervisors keep safety items in reserve for any student who might have forgotten to bring his own personal items.

The students are also instructed on how to act in the event of an emergency and safely evacuate the workshop. A hard copy of the Safety Regulation booklet is available in all labs and distributed electronically in PDF format to all faculty members, staff and students. An Accident Report Form is also available with the workshop supervisor to report any accident to the Dean’s office.

Classrooms, offices and corridors are equipped with smoke detectors, and fire alarms are installed where needed. Each lab is also equipped with first aid kits, lab safety manual, and general safety instructions printed on a large-scale notice board. This is in addition to signs showing the laboratory title and the emergency exit doors. The engineering building has a centrally installed fire alarm system and fire extinguishing water systems. Portable fire extinguishers are regularly checked and dated by the University Maintenance Department. The Departmental Workshop and Labs Committee, the Faculty of Engineering Facilities Unit and the University General Administration for Security and Safety run periodic auditing of safety in laboratories.

4. Maintenance and Upgrading of Facilities

The Electrical and Computer Engineering (ECE) Department consistently maintains and updates the facilities allocated to its undergraduate program to ensure that the instructional and learning environment is adequate and safe for the intended purposes.

D.1 Maintenance of Program Facilities

Equipment maintenance and management in each lab is the responsibility of the laboratory engineer or the laboratory technicians. Their duty is to keep the equipment in good and safe working condition. Any equipment needing repair beyond the capabilities of the program staff is sent to the university’s Scientific Equipment Maintenance Center (SEMC), which is ultimately responsible for all technical equipment in the university. If the maintenance is also beyond the capabilities of SEMC, the supplier of the equipment is called upon to get the equipment repaired. The university maintenance crew only handles building maintenance and utility related problems.

Computer hardware and software are maintained within the program by the IT Unit of the Faculty of Engineering, which is responsible for the servicing, maintenance and upgrading of computer equipment, computer networks, and computer software.

The engineers and technicians in the computer laboratories are responsible for installing, and maintaining the necessary specialized software needed for course teaching; they are also responsible for providing the students with the software they need to complete their assignments at home.

D.2 Upgrading of Facilities

The Program is committed for continuous upgrading and development of its laboratories including, equipment, staff and space wherever possible. The process of upgrading is handled as follows. The Department has a Laboratory Committee with the task of updating and furnishing various laboratories with new equipment and materials. This committee is formed of faculty members, laboratory instructors and engineers in the Program. All labs have full time engineers with a faculty member as a laboratory supervisor. The Laboratory Committee is responsible for establishing and enforcing general laboratory policies. The committee allocates the laboratory-specific resources to purchase materials, software, and equipment for both the undergraduate teaching laboratories and the research and support facilities and to upgrade facilities. The Program faculty, engineers and technicians are continuously encouraged to make suggestions or to submit requests for whatever they feel is needed for equipment maintenance, course work, or facilities upgrades. This committee sets the priorities for spending and, as necessary, establishes a timetable for the replacement of aging equipment.

The budget allocated to the Program for equipment acquisition and running of the Program laboratories and other facilities varies on year to year basis. The Program also has gotten donations from national companies in the form of equipment, although in the recent past this has not materialized. The money from the Program’s allocated budget and the funding and donations from the above sources is adequate for our current needs and future development. In addition, the funded research grants present another resource for purchasing measuring instruments and data acquisition equipment for instructional needs.

The Laboratory Committee decides about the laboratory-specific needs in terms of materials, software, and equipment for the instructional laboratories. The Department faculty, engineers and technicians are continuously encouraged to make suggestions and to submit requests for all their needs related to equipment maintenance, course work, or facilities upgrades. Facilities upgrade requests are first submitted to the chairman of the department, then to the dean of the faculty of engineering, and if approved, they are forwarded to the Administration of Academic Services. This administration has four departments to handle incoming requests:

• Department of Classrooms and Teaching Aids
• Department of Laboratories
• Department of Educational Media
• Scientific Equipment Maintenance Center (SEMC)

5. Library Services

The central library of King Abdulaziz University, maintained and operated by the Deanship of Library Affairs, is available for all KAU students. The library houses a full collection of engineering books, journals, and databases. Library material is shelved as an open stack policy using the Dewey Decimal Classification Scheme. The library collection is accessible to faculty members and students alike at their leisure. Professional librarians are available to assist.

The references staff handles Inter-Library Loans with other libraries in the Kingdom. The library contains nearly one million Arabic and non-Arabic books, reference materials, manuscripts, dissertations, and reports in different branches. The central library subscribes to various databases and has a wide range of periodicals, books, and other publications in aerodynamics, propulsion, control, materials, and structures. Reference services are available to the students and the faculty as well as access to PC networks. The Deanship of Library Affairs typically requests the program each year to provide it with up to one hundred new book titles related to the program to purchase in the following year.

The Deanship of Library Affairs has a digital library that allows students and faculty to access all information resources through the Internet and intranet. Examples of these resources include the Saudi Digital Library (SDL), ScienceDirect, Web of Science (ISI), IEEE, SpringerLink – Springer, Wiley, E-Journals, E-books and different databases such as EBSCO, Cambridge Journals, and others. These resources may be accessed through the web page of the Deanship of Library Affairs at   http://library.kau.edu.sa.

In summary: The facilities of the program and the support the program has been receiving for their maintenance and upgrading are adequate to support the attainment of the student outcomes. In particular, the new buildings have improved the adequacy of the facilities for the intended instruction and for the attainment of the student outcomes. The larger space afforded by the program has also contributed to foster faculty-student interaction and provide opportunities to the students to use modern engineering tools and to the faculty to enhance their research outcomes.
