An Adaptive Approach to Optimal Sparse Mobile-target Search Planning using Heterogeneous Agents
Planning an effective search for locating mobile-targets is essential in a variety of scenarios (e.g., search and rescue, environmental monitoring, law enforcement, etc.). Effective planning is especially important when resources are sparse (i.e., they are insufficient to search a significant …

Reducing deadline miss rate for grid workloads running in virtual machines: a deadline-aware and adaptive approach
… all I/O to increase network throughput. This approach limits the change impact on the existing grid infrastructure while leveraging the execution and performance isolation capabilities of virtualization for job execution. This work led to evaluation of various scheduling strategies used by the …

Adaptive governance of contested rivers : a political journey into the uncertain
… explores what I call the conventional versus the adaptive approach to international river basin governance. The former makes it hard to adjust over time; the latter, less so. Climate change appears to be increasing the need for flexibility in river basin governance. So, I compare how institutional …

Symbiotic synergies : adaptive framework for polydisciplinary collaboration in performance practice
… of distinct creative disciplines, and what approaches can enhance such engagements? This inquiry is investigated through Practice Research with project-based and iterative methodology aiming towards developing a novel framework for organising collaborative environments. Presented here is the …

Spline wavelet image coding and synthesis for a VLSI based difference engine
… spline :V1RA. Based on these properties, an adaptive image synthesis system is developed which enables one to reduce the number of instruction cycles required to reproduce images compressed using the quadratic spline wavelet transform. This adaptive approach is computationally simple and …

Planning autonomous evacuation for access and flood resilience
… discussion, with the shifting attitude toward an adaptive approach where landscapes serve a multitude of functions. Cities like Boston are at the forefront in resilience planning with initiatives such as the Climate Ready Boston. The history-rich land morphology of Boston shows a real …

THE POLITICAL DYNAMICS OF THE IRAQI MARJAʿIYYA
… ‘Ali al-Sistani. Findings reveal a nuanced, adaptive approach by the marjaʿiyya, shaped by context and shifting between activism and quietism. The study highlights the marjaʿiyya’s pivotal role in shaping Iraq’s political trajectory and its broader implications for understanding the …

Adaptive turn-prohibition routing algorithm for the networks of workstations
… in Myrinet switches. However, most of existing approaches for deadlock-free routing either try to eliminate any possibility of deadlock occurrence, which can result in putting extra restrictions on the routing in the networks or put no restrictions on routing, which leads to other approach …

The role of adaptivity in a numerical method for the Cox-Ingersoll-Ross model
We demonstrate the effectiveness of an adaptive explicit Euler method for the approximate solution of the Cox-Ingersoll-Ross model. This relies on a class of path-bounded timestepping strategies which work by reducing the stepsize as solutions approach a neighbourhood of zero. The method is hybrid …

Adaptive mesh construction for the numerical solution of stochastic differential equations with Markovian switching
In this dissertation we demonstrate an approach to the numerical solution of nonlinear stochastic differential equations with Markovian switching. Such equations describe the stochastic dynamics of processes where the drift and diffusion coefficients are subject to random state changes according to …

Spatial diagnosis and media treatments
Contemporary approaches toward the renovation of existing spaces are mainly driven by functional requirements and aesthetic purposes. While this design approach is valid, the purpose of this thesis is to develop a methodology for architects to analyze and evaluate the quality of existing spaces on …

A Pervasive Middleware for Activity Recognition with Smartphones
… number of sensor devices and data demands new approaches for adaptive, lightweight and accurate AR. We propose a new middleware called the Pervasive Middleware for Activity Recognition (PEMAR) to address these problems. We implemented PEMAR on a Big Data platform incorporating machine-learning …

Marginal strips : how best to allow public access to lakes, rivers and the sea?
… the policy's underlying theory. Two alternative approaches for the provision of public access are examined: First the use of covenants, and second the adoption of a partial "Right of Common Access". From the analysis undertaken it is suggested that a more adaptive approach is required if secure …

Probabilistic and learning approaches through concurrent parameter estimation and adaptive control for in-space robotic assembly
… is essential. In order to achieve this, approaches that employ a unified framework between parameter estimation and learning methodologies through a Composite Adaptation (CA) structure are presented. Furthermore, to evaluate the likelihood of mission success or objective completion, a …

Evolutionary learning multi-agent based information retrieval systems
… This thesis addresses this problem with an adaptive approach that relies on evolutionary user-modelling. The proposed information retrieval system learns user needs from user-provided relevance feedback. The method combines a qualitative feedback measure obtained using fuzzy inference, and …
