Principles of Physiologically Adequate Lighting & Measurement

Principles of Physiologically Adequate Lighting & Measurement

Visible Light

Visible light spectrum: 500/600-700/800 nm

Types of Inadequate Lighting

Insufficient Light

Not enough light for the visual task.

Glare

Too much light for the need. Occurs when a bright light source or reflection interferes with object visibility.

Causes of Reflected Glare:
  • Light reflected from polished, shiny, or glossy surfaces
  • Glass on picture frames or windows at night
  • Monitors/screens
Causes of Direct Glare:
  • Very bright light

Introduction to Geographic Information Systems (GIS)

Fundamental Concepts in GIS

a. Characterizing Geographic Concepts

In the discrete object view, the world is seen as empty except where occupied by objects with well-defined boundaries. Examples include lakes in Minnesota or mountains in Scotland.

In the continuous field view, the world is described by variables measurable at any point on Earth’s surface, with values changing across the surface.

b. Digital Representation

Discrete objects are represented using vector data, while continuous fields are represented

Software Evolution, Maintenance, and Reengineering: Managing Legacy Systems

Lehman’s Laws of Software Evolution

Inevitable Evolution: The first law states that maintaining a software system is an inevitable process. As the system’s environment changes, new requirements emerge, necessitating system modifications. These modifications, when reintroduced into the environment, trigger further environmental changes, restarting the cycle of evolution.

Degradation of Structure: The second law posits that system changes lead to structural degradation. The only way to mitigate this
