THE UNIFIED SOIL CLASSIFICATION SYSTEM MAPPING OF THE PANNONIAN BASIN IN CROATIA USING MULTINOMINAL LOGISTIC REGRESSION AND INVERSE DISTANCE WEIGHTING INTERPOLATION

Rudarsko-geološko-naftni Zbornik, 2023
The Unified Soil Classification System (USCS) is the basis for numerous methods for soil trafficability research. Since USCS data are not always available, various other data and methods are used to correlate and predict the USCS soil group.

Analysis and Experiment of a Bioinspired Multimode Octopod Robot

Chinese Journal of Mechanical Engineering, 2023
Legged robots use isolated footholds to support, which have the merit of good terrain trafficability but lack speed ability. In contrast, wheeled robots have the advantages of high speed and efficiency but only run on flat roads.

Traffic Management

, 2003
Quality of service in network communication is mainly assured by traffic management consisting in a variety of protocols and mechanisms whose role is to prevent the network from being congested. Traffic management has been a very active area of research for two decades following the conception of packet-switched integrated services networks, such as ...
