Design Example: Sustainability in Concrete Building

Design Example: Sustainability in Concrete Building

As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground...

Design Consideration

Design Consideration

Designing a structure involves a series of considerations, primarily the material's ultimate strength, calculated through tests that measure changes under increased force until the material reaches its breaking point or limit. The ultimate load, where the material breaks, is divided by its original cross-sectional area, resulting in the ultimate normal stress or strength. The ultimate shearing stress is another significant factor taken into account.
The factor of safety is another key...

Design Example: Marking Boundaries of a Site Using a Compass

Marking site boundaries using a compass is a precise surveying technique that ensures the accuracy of boundary delineation. The process begins by using provided site details, including the bearings and lengths of each boundary line. The initial step involves calculating latitudes and departures for all sides of the site. This computation verifies that the traverse is free of errors, ensuring a closed and accurate boundary.The process starts at a known point, such as Point A, which is often...

Design Example: Identifying the Locations of Monuments in the Field Using Global Positioning System Device

Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point...

Design Example: Alignment of a Road Line Using GIS

Design Example: Alignment of a Road Line Using GIS

The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

Design Example: Measuring Distance Between Two Points with Obstructions

Design Example: Measuring Distance Between Two Points with Obstructions

When measuring distances in areas with physical obstructions, such as a lake in a field, surveyors must employ techniques to calculate accurate lengths without direct line measurements. One effective method is the offset technique, which allows for precise distance estimation over inaccessible stretches.In this scenario, a surveyor must measure a side of an area that crosses a lake. Since the measuring tape cannot span the lake, the surveyor begins by establishing a baseline that aligns with...

Area of Science:

Computer Science
Human-Computer Interaction
Accessibility Engineering

Background:

Indoor mobility and wayfinding present unique challenges compared to outdoor navigation, as GPS is not readily available.
Effective indoor navigation is crucial for individuals with disabilities, particularly the visually impaired, and beneficial for all unfamiliar users.
Existing solutions often lack inclusivity, necessitating a user-centered approach for widespread adoption.

Purpose of the Study:

To design, implement, and deploy an inclusive indoor navigation system for a university community.
To provide accessible wayfinding functions leveraging Internet of Things (IoT) infrastructure and a mobile application.
To address the specific needs of diverse user groups, including students with disabilities, campus students, and visitors.

Main Methods:

An inclusive by design approach was adopted for system development.
An Internet of Things (IoT) infrastructure was integrated with an accessible mobile application.
A real-world case study was conducted at the University of Bologna, considering diverse building types, including historical structures.

Main Results:

The system was evaluated in three distinct scenarios with varied user groups (students with disabilities, campus students, visitors).
All participants reported satisfaction with the system's functionalities.
The indoor localization strategy proved effective in delivering a positive wayfinding experience.

Conclusions:

The developed system successfully enhances indoor mobility and wayfinding for a university community.
The inclusive design approach ensures the system benefits a wide range of users, including those with impairments.
The system's adaptability to different building configurations demonstrates its practical applicability in real-world settings.
