Adaptive spectral estimators for fast flow-profile detection
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2013In multigate spectral Doppler (MSD) analysis, hundreds of small sample volumes (SVs) aligned along a pulse wave-line can be simultaneously investigated. The so-called spectral profile, reporting the scatterers' velocity distribution in a vessel, is obtained by estimating the frequency content of the echoes detected from each SV. The preferred frequency

Adaptive shaping of femtosecond polarization profiles
Journal of the Optical Society of America B, 2003We report the experimental implementation of femtosecond polarization pulse shaping within an adaptive learning loop. This technique makes it possible to optimally and automatically generate light fields in which intensity, momentary frequency, and light polarization (i.e., ellipticity and orientation) change as a function of time within a single ...

Performance-Based Adaptability Profiles in Multitasking
Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2013Assessing a person’s ability to multitask is a topic that is gaining increased attention. However, task constraints and difficulty rarely remain constant in real-world environments; when task constraints change, people must adapt to avoid diminished task performance or failure.

Profile Adaptation in Adaptive Information Filtering: An Immune Inspired Approach
2009 International Conference of Soft Computing and Pattern Recognition, 2009Within the context of information filtering, learning and adaptation of user profiles is a challenging research area and is, in part, addressed by work in Adaptive Information Filtering (AIF). In order to be effective in a dynamic context, maintaining filtering performance, information filtering systems need to adapt to changes.

Regularized antenna profile adaptation in online hyperthermia treatment
Medical Physics, 2010Purpose:Online optimization of annular‐phased‐array hyperthermia (HT) is based on planning tools and magnetic resonance (MR) thermometry. Until now, the method has been validated in phantoms. Further developments and extensions are required for clinical purposes.

Adapt, endure, succeed: profiling extreme teams
Team Performance Management: An International JournalPurpose Extreme teams are found in a great variety of contexts, from firefighting to space exploration. The number of extreme teams (alongside research on them) has exponentially increased in the last two decades. Thus, the purpose of this study is to examine the internal team dynamics of extreme teams, identify

A Generic User Profile Adaptation Framework
2010The paper presents a recommender system that permits to manage user preferences using linguistic criteria and, after collecting information about selections made by the user, it performs an unsupervised adaptation of the user profile. It has been implemented as a Web application and designed in a generic way so that it can be applied to any decision ...
