Abstract: Hands-on experiences in engineering education are highly valued by students. However, the high cost, large size, and non-portable nature of commercially available laboratory equipment often confine these experiences to lab courses, separating practical demonstrations from classroom teaching. Consequently, mechanical engineering students may experience a delay in practical engagement as lab sessions typically follow theoretical courses in subsequent semesters, a sequence that differs from mechatronics, electrical, and computer engineering programs. This study details the design and development of portable and cost-effective control lab equipment that enables in-class demonstrations of a proportional-integral-derivative (PID) controller for the trajectory and speed control of a DC motor using MATLAB Simulink, as well as disturbance control. The equipment, composed of a DC motor, beam, gears, crank, a mass, and propellers, introduces disturbances using either propellers or a rotating unbalanced mass. All parts of the equipment are 3D printed from polylactic acid (PLA). Furthermore, the beam holding the propellers can be attached to Quanser Qube lab equipment, which is widely used in control laboratories. The lab equipment we present is adaptable for demonstrations, classroom projects, or as an integral part of lab activities in various engineering disciplines.

ABSTRACT: The university campus in the United States is a unique architectural and landscape architecture typology. Nothing like it existed until Harvard University was established in 1638. Invented during in the 17th century by the American colonists and later developed during the American Industrial Revolution, the American campus is a community devoted to teaching and generating knowledge. It can be urban, suburban, and/or rural in form and its planning directly correlates with a university’s research mission and the pedagogy of the American university system. Its buildings and landscapes are embedded with iconography, which the founding builders used to convey their values to future generations.
This paper presents the history of how this designed work first emerged in American society and then evolved in ways that responded to changes that occurred in America. At the end of the 20th century, universities conserved parts of them as cultural heritage monuments. Originally, the university campus was built to disseminate a classical education, but later, the campus was built for technical and agricultural education. By the beginning of the 20th century, professional education and sport changed its architecture and landscape. The paper briely discusses that while it has inspired how universities are built to teach and generate knowledge throughout the world. It concludes by reairming its value to cultural heritage and that it should be conserved.
OSU was founded in 1890 as Oklahoma Agricultural and Mechanical College under the Morrill Land Grant Act of 1862 set in motion by President Abraham Lincoln. It has approximately 30,000 students across 1500 acres with 400 buildings. Its athletic department runs an operating budget of about $100 million.
Today we sweep through standards action in building glazing, entrances and means of egress. The word fenestration (Latin: fenestra) has become a term of art for the design, construction, and placement of openings in a building, including windows, doors, skylights, and other glazed elements. While the word has sparse use in the International Code Council and National Fire Protection Association catalog it is widely used by the Construction Specifications Institute in its MasterFormat system for organizing construction standards, guidelines and building contracts.
The percentage of a building envelope “skin” that is comprised of doors and windows varies depending on the specific building design, function, and location. However, a commonly cited range is between 15% to 25% of the total building envelope. The actual percentage will depend on several factors such as the building’s purpose, orientation, local climate, and energy performance goals. Buildings that require more natural light or ventilation, such as schools, hospitals, and offices, may have a higher percentage of windows and doors in their envelope. In contrast, buildings with lower lighting and ventilation requirements, such as warehouses, may have a smaller percentage of windows and doors.
Fenestration presents elevated risk to facility managers. The education facility industry is a large target and a pattern of settling out of court. For example:
In 2013, a former student at Yale University sued the school over a broken window in her dorm room. The student alleged that the university was negligent in failing to repair the window, which allowed a burglar to enter her room and sexually assault her. The case was settled out of court in 2015 for an undisclosed amount.
In 2019, a student at the University of California, Los Angeles sued the school over a broken window in her apartment. The student alleged that the university was negligent in failing to repair the window, which allowed a swarm of bees to enter her apartment and sting her. The case was settled out of court for $4.5 million.
In 2020, a group of students at Harvard University sued the school over its decision to require them to move out of their dorms due to the COVID-19 pandemic. The students alleged that the university breached its contract with them by failing to provide suitable alternative housing, including functioning windows and doors. (The case is ongoing; best we can tell as of the date of this post).
These cases illustrate that colleges and universities can face legal action related to doors and windows, either due to alleged negligence in maintaining or repairing them, or due to issues related to student housing and accommodations.
