Adressing static and dynamic errors in bandpass unit element multibit DAC's [PDF]

, 2004
This paper describes a general model for static as well as dynamic errors in multibit unit element DAC's. Apart from the static mismatch there are two other error terms arising from switching imperfections.

Research on AGV Path Optimization Based on an Improved A* and DWA Fusion Algorithm

Forests
Forestry environments—such as logging sites, transport trails, and resource monitoring areas—are characterized by rugged terrain and irregularly distributed obstacles, which pose substantial challenges for AGV route planning. This poses challenges for route planning in automated guided vehicles (AGVs) and forestry machinery. To address these challenges,

The Potential Impact of Increased Irrigation Water Tariffs in South Africa [PDF]

In South Africa, a water scarce country, conflict between water users is mounting, while there are few remaining bulk water augmentation options. Water demand management is thus increasingly taking centre stage in water management debates.
