Discrete Spherical Harmonic Transforms (SHTs) are commonly defined for equiangular grids on the sphere. However, when global array data exhibit near equidistributed patterns rather than equiangular grids, discrete SHTs require appropriate adaptations for analysis and synthesis. Computational efficiency and reliability impose structural constraints on possible equidistribution characteristics of...

BACKGROUND Study-based global health interventions, especially those that are conducted on an international or multi-site basis, frequently require site-specific adaptations in order to (1) respond to socio-cultural differences in risk determinants, (2) to make interventions more relevant to target population needs, and (3) in recognition of 'global health diplomacy' issues. We report on the ad...

We describe a framework for top-down centralized self-adaptive MASs where adaptive agents are “protocol-driven” and adaptation consists in runtime protocol switch. Protocol specifications take a global, rather than a local, perspective and each agent, before starting to follow a new (global) protocol, projects it for obtaining a local version. If all the agents in the MAS are driven by the same...

This paper presents a solution to the problem of global, output feedback, tracking control of uncertain robot manipulators. Specifically, a desired compensation adaptation law plus a nonlinear feedback term coupled to a dynamic nonlinear filter is designed to produce global asymptotic link position tracking while compensating for parametric uncertainty and requiring only link position measureme...

The performance of many supervised and unsupervised learning algorithms is very sensitive to the choice of an appropriate distance metric. Previous work in metric learning and adaptation has mostly been focused on classification tasks by making use of class label information. In standard clustering tasks, however, class label information is not available. In order to adapt the metric to improve...

BACKGROUND AND AIM Factors promoting family adaptation to child's disability are poorly studied together. The aim of the study was to describe the family adaptation to disability and to identify determinants associated with using a global theoretical model. MATERIALS AND METHODS 286 families of teenagers [13-17 years] with cerebral palsy (CP) from 4 European disability registers were included...

Understanding the genetic basis of adaptation has been and remains to be one major goal of ecological and evolutionary genetics. The variation in diapause propensity in the model organism Drosophila melanogaster represents different life-history strategies underlying adaptation to regular and widespread environmental heterogeneity, thus provides an ideal model to study the genetic control of ec...

Transport layer and application layer of network stack use end-to-end adaptation protocols (e.g., TCP and bitrate-adaptive video) to achieve high performance by continuously adapting endpoint behavior to changes of network conditions. The traditional belief is that these protocols must be run independently by endpoints to achieve desirable performance. In essence, they use reactive logic trigge...

In 1978, at the first conference to discuss the emerging field of conservation biology, there were 4 billion people on Earth. Now there are more than 7 billion, with 10.1 billion projected by 2100. Sustainably meeting the needs of 10 billion people and conserving natural resources at the same time will require profound creativity and innovation. Scholars who study human-caused climate change ha...

As software systems today increasingly operate in changing and complex environments, they are expected to dynamically adapt to the changing environments sometimes with multiple co-existing adaptation goals. This paper proposes an adaptation framework to facilitate adaptation with multiple concerns by using reusable and composable adaptation modules. Rather than using one-size-fits-all approach,...
