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.

The University Campus As A Designed Work and an Artefact of Cultural Heritage

The University Campus in the United States—As a Designed Work to Produce Knowledge; and as an Artefact of Cultural Heritage

Paul Hardin Kapp
School of Architecture, University of Illinois at Urbana-Champaign, Illinois, United States

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.

Masonry

Harvard University Dormitory Room | Smithsonian Museum | Thomas Warren Sears Collection

Today we sort through the best practice literature for designing and building education settlements with brick — the world’s oldest construction material. Masonry is a term used to describe the construction of structures using individual units that are bound together with mortar. Brickwork is a specific type of masonry that involves the use of bricks as the primary building units.

We use the terms interchangeably reflecting vernacular use in the literature. Brickwork in building construction lies in its ability to provide structural strength, fire resistance, thermal and sound insulation, aesthetic appeal, low maintenance, environmental friendliness, cost-effectiveness, and versatility.

Masonry is a construction technique that involves the use of individual units, typically made of materials like brick, stone, concrete blocks, or clay tiles, which are bound together with mortar to create walls, columns, or other structural elements. Masonry has been used for thousands of years and remains a popular method for building various structures, including houses, commercial buildings, bridges, and more.

The key components of masonry construction are:

Masonry Units: These are the individual building blocks or pieces, such as bricks or stones, that form the structure. They come in various shapes, sizes, and materials, depending on the specific requirements of the project.
Mortar: Mortar is a mixture of cement, sand, and water that is used to bind the masonry units together. It acts as both an adhesive and a filler between the units, providing strength and stability to the structure.
Masonry Workmanship: Skilled craftsmen, known as masons, are responsible for arranging and securing the masonry units with mortar. Their expertise ensures the structural integrity and aesthetic quality of the finished product.

Masonry construction offers several advantages:

Durability: Masonry structures are known for their longevity and resistance to fire, weather, and pests.
Aesthetic Appeal: Masonry can be used to create intricate designs and patterns, making it a popular choice for architectural and decorative elements.
Energy Efficiency: Masonry walls have good thermal mass, which can help regulate indoor temperatures and reduce energy costs.
Low Maintenance: Masonry structures typically require minimal maintenance over the years.

Masonry can be categorized into different types based on the materials and methods used. Some common forms of masonry include:

Brick Masonry: This involves using clay or concrete bricks to build walls and structures. It is widely used in residential and commercial construction.
Stone Masonry: Natural stones, such as granite, limestone, and slate, are used to create walls and structures in this type of masonry. It’s often used for historical or architectural projects.
Concrete Block Masonry: Concrete blocks are used to construct walls in this form of masonry, and it’s commonly seen in industrial and commercial buildings.
Reinforced Masonry: Steel reinforcement is incorporated into masonry walls to enhance structural strength.

Fenestration

The oldest door still in use in Pantheon (115 A.D.)

“No work of art can be great,

if it is not composed of the smallest things.”

— Vitruvius (Book VII, Chapter 9)

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.
