Self-determination and persistence in a real-life setting: Toward a motivational model of high school dropout.
- Journal of Personality and Social Psychology,
, 1997
"... The purpose of this study was to propose and test a motivational model of high school dropout. The model posits that teachers, parents, and the school administration's behaviors toward students influence students' perceptions of competence and autonomy. The less autonomy supportive the so ..."

RIGHT CENSORED RAYLEIGH MODEL: SHRINKAGE AND RELIABILITY ESTIMATORS
"... The Rayleigh distribution (as a special case of the Weibull distribution), and essentially its censored counterpart, is considered such as to derive objective estimators for various quantities. [1], [2], and [4] derived and juxtaposed the Bayesian estimators under certain loss functions, with specif ..."

, with specific reference to the Jeffreys prior and other objective prior choices. This presentation aims to generalize the chosen objective prior distribution to derive estimators for the parameter under each loss function considered, all in the Bayesian paradigm. Shrinkage estimators and reliability estimators
METHODS AND STANDARDS FOR LOSSLESS COMPRESSION
"... Lossless compression refers to compression methods for which the original uncompressed data set can be recovered exactly from the compressed stream. The need for lossless compression arises from the fact that many applications, such as the compression of digitized medical data, require that no loss ..."

Remembering over the short-term: The case against the standard model.
- Annual Review of Psychology,
, 2002
"... s Abstract Psychologists often assume that short-term storage is synonymous with activation, a mnemonic property that keeps information in an immediately accessible form. Permanent knowledge is activated, as a result of on-line cognitive processing, and an activity trace is established "in&quo ..."

1Compressive Link Acquisition in Multiuser Communications
"... Abstract—An important receiver operation is to detect the presence specific preamble signals with unknown delays in the presence of scattering, Doppler effects and carrier offsets. This task, referred to as “link acquisition”, is typically a sequential search over the transmitted signal space. Recen ..."

-off in complexity and performance that is possible when using sparse recovery. To do so, we propose a sequential sparsity-aware compressive sampling (C-SA) acquisition scheme, where a compressive multi-channel sampling (CMS) front-end is followed by a sparsity regularized likelihood ratio test (SR-LRT) module
Reliable Tracking with Intermittent Communications
"... Abstract — We consider the problem of distributed target tracking of a linear dynamical system via networked sensors. Our setup consists of a set of sensors connected to a fusion center by means of communication links. Unreliable communication channels leads to communication delays and loss of infor ..."

Analysis, Representation and Compression of ECG signals
"... - it is a time-varying signal;- analysis of the local morphology of the ECG and its time varying properties is an important clinical diagnostic tool; ECG signals- are associated with electrical changes known as depolarization and repolarization of the atria and ventricles. ECG signals- need to be st ..."

to be stored and compressed without significant loss of signal quality;- this requires reliable and adequate methods;- the P wave in the ECG signal is a result of the contraction of the atria;- the contraction of the ventricles produces the QRS complex;- its repolarization manifests itself in the T wave
RICE UNIVERSITY Regime Change: Sampling Rate vs. Bit-Depth in Compressive Sensing
, 2011
"... The compressive sensing (CS) framework aims to ease the burden on analog-to-digital converters (ADCs) by exploiting inherent structure in natural and man-made signals. It has been demon-strated that structured signals can be acquired with just a small number of linear measurements, on the order of t ..."

Synchronizing parallel data streams via . . .

Streaming very-high-definition visualization data objects on top of optical networks is critical in many scientific research areas, including video streaming/conferencing, remote rendering on tiled display walls, 3D virtual reality applications, etc. Current data streaming protocols rely on UDP as w ..."

as well as a variety of compression techniques. However, none of the protocols scale well to the parallel streaming model of large scale graphic applications, and the existing parallel streaming protocols have limited synchronization mechanisms to synchronize the streams efficiently, and are prone
