This paper presents an integrated framework for system identification. This framework provides a useful tool for obtaining and validating system models. Once the model is synthesized, a validation process is applied to a real-time implementation within the Real-Time Virtual Test Bed (RTVTB). As a demonstration, a 3 rd -order filter is taken as the system under test (SUT). The system identificat...

In 2015, NIST conducted the most recent in an ongoing series of Language Recognition Evaluations (LRE) meant to foster research in language recognition. The 2015 Language Recognition Evaluation featured 20 target languages grouped into 6 language clusters. The evaluation was focused on distinguishing languages within each cluster, without disclosing which cluster a test language belongs to. The...

This paper describes the most relevant features of a collaborative multi-site submission to the NIST 2011 Language Recognition Evaluation (LRE), consisting of one primary and three contrastive systems, each fusing different combinations of 13 state-of-the-art (acoustic and phonotactic) language recognition subsystems. The collaboration focused on collecting and sharing training data for those t...

The Dutch Folktale Database contains fairy tales, traditional legends, urban legends, and jokes written in a large variety and combination of languages including (Middle and 17th century) Dutch, Frisian and a number of Dutch dialects. In this work we compare a number of approaches to automatic language identification for this collection. We show that in comparison to typical language identifica...

Wuyi Rock tea, well-recognized for rich flavor and long-lasting fragrance, is a premium subcategory of oolong tea mainly produced in Wuyi Mountain and nearby regions of China. The quality of tea is mainly determined by the chemical constituents in the tea leaves. However, this remains underexplored for Wuyi Rock tea cultivars. In this study, we investigated the leaf metabolite profiles of 14 ma...

AIMS To examine the link between hazardous drinking and level of sport participation in New Zealand. METHODS Sports science and general university students (n = 427) completed a sporting profile questionnaire that included the Alcohol Use Disorders Identification Test (AUDIT). RESULTS Elite sportspeople (both provincial and international/country level) reported higher rates of hazardous dri...

This Paper presents an analysis of test data recorded during flight trials of a gyroplane. This class of rotarywing aircraft has found limited application in areas other than sport or recreational flying. However, the accident rate is such that a study of the configuration's stability and control characteristics is timely, and in addition substantive data is required for a new airworthiness and...

One of the major challenges of the language identification (LID) system comes from the sparse training data. Manually collecting the linguistic data through the controlled studio is usually expensive and impractical. But multilingual broadcast programs (Voice of America, for instance) can be collected as a reasonable alternative to the linguistic data acquisition issue. However, unlike studio c...

In Mars rover missions, a high degree of accuracy in localization of the rover and mapping of the surrounding terrain is of fundamental importance for safe rover navigation and for achievement of scientific and engineering goals. In the Mars Exploration Rover (MER) 2003 mission, ground image-based incremental bundle adjustment (BA) technology has been performed on Earth to correct rover positio...

Sorting is a useful predictor for permeability. We show how to invert seismic data for a permeable rock sorting parameter by incorporating a probabilistic rock-physics model with floating grains into a Bayesian seismic inversion code that operates directly on rock-physics variables. The Bayesian prior embeds the coupling between elastic properties, porosity, and the floating-grain sorting param...
