Estimation and fault diagnosis for vehicle energy systems
… systems. The framework consists of a multilevel hierarchical network of observers with each level having a unique update rate. To account for the significant interactions between subsystems, a novel bidirectional coordination strategy is developed. Sufficient conditions for the stability and …

The influence of hypertext linking structures and task-related variables on information retrieval tasks
… system linking structures consisting of linear, hierarchical, network, and combination hierarchical/network configurations. These commonly used hypertext linking structures were imposed on a text-intensive geography database (GEO). GEO contains 187 nodes discussing a variety of topics concerning …

Informacijos saugumo užtikrinimo metodų tyrimas Block chain pagalba /
Blockchains created a method to save data in the network where each node has identical state witout using central authority to it. Such trustless systems do not have a signle point of failure, which makes them more robust against hacking or a influence from a single party, they are harder to shut …

Wet Chicago: Prohibition and the Development of the Informal Alcohol Economy
… market to the development of a complex and hierarchical network of alcohol distribution that spanned across neighborhoods and outside the region. This illicit exchange of booze affected both culture and identity and became closely aligned with politicians and enforcement …

Hierarchical control for multi-domain coordination of vehicle energy systems with switched dynamics
This dissertation presents a hierarchical control framework for vehicle energy management. As a result of increasing electrification, legacy integration and control approaches for vehicle energy systems have become limiting factors of performance and cannot accommodate the requirements of …

Film festivals in Africa: a study in sustainability
… due to the existence of a global film festival hierarchical network, within which film festivals in Africa sit near the bottom. It is also apparent from this analysis that to become sustainable film festivals in Africa must effectively leverage these four factors through authentic claims to …

Towards Nootropia : a non-linear approach to adaptive document filtering
… with a single, multi-topic user profile. A hierarchical term network that takes into account topical and lexical correlations between terms and identifies topic-subtopic relations between them, is used to represent a user's multiple topics of interest and distinguish between them. A series …

Hybrid routing and bridging strategies for large scale mobile ad hoc networks
Multi-hop packet radio networks (or mobile ad-hoc networks) are an ideal technology to establish "instant" communication infrastructure for military and civilian applications in which both hosts and routers are mobile. In this dissertation, a position-based/link-state hybrid, proactive routing …

Localized Quality of Service Routing Algorithms for Communication Networks. The Development and Performance Evaluation of Some New Localized Approaches to Providing Quality of Service Routing in Flat and Hierarchical Topologies for Computer Networks.
… components of the QoS framework in communication networks. The concept of QoS routing has emerged from the fact that routers direct traffic from source to destination, depending on data types, network constraints and requirements to achieve network performance efficiency. It has been introduced to …
