A Neural Network Approach To Key Frame Extraction, Rajesh Narasimha, Andreas Savakis, Raghuveer M. Rao, Ricardo De Queiroz Dec 2003

A Neural Network Approach To Key Frame Extraction, Rajesh Narasimha, Andreas Savakis, Raghuveer M. Rao, Ricardo De Queiroz

Articles

We present a neural network based approach to key frame extraction in the compressed domain. The proposed method is an amalgamation of both the MPEG-7 descriptors namely motion intensity descriptor and spatial activity descriptor. Shot boundary detection and block motion estimation techniques are employed prior to the extraction of the descriptors. The motion intensity (“pace of action”) is obtained using a fuzzy system that classifies the motion intensity into five categories proportional to the intensity. The spatial activity matrix determines the spatial distribution of activity (“active regions”) in a frame. A neural network is used to pick those frames as …


Isotropic Loop Quantum Cosmology With Matter. Ii. The Lorentzian Constraint, F. Hinterleitner, Seth Major Dec 2003

Isotropic Loop Quantum Cosmology With Matter. Ii. The Lorentzian Constraint, F. Hinterleitner, Seth Major

Articles

The Lorentzian Hamiltonian constraint is solved for isotropic loop quantum cosmology coupled to a massless scalar field. As in the Euclidean case, the discreteness of quantum geometry removes the classical singularity from the quantum Friedmann models. In spite of the absence of the classical singularity, a modified DeWitt initial condition is incompatible with a late-time smooth behavior. Further, the smooth behavior is recovered only for positive or negatives times but not both. An important feature, which is shared with the Euclidean case, is a minimal initial energy of the order of the Planck energy required for the system to evolve …

Information Literacy Programmes And Course Curricula: The Case For Integration, Anne Ambrose, Brian Gillespie Nov 2003

Information Literacy Programmes And Course Curricula: The Case For Integration, Anne Ambrose, Brian Gillespie

Articles

The advent of the Internet and the profusion, complexity and haphazard nature of the information available through electronic and digital resources has highlighted the issue of information literacy in third level institutions worldwide. How do we deal with the information explosion to which we are subjected on a daily basis? In particular how do our students learn to exploit the range of resources available to advance their studies and research? Can these students become fully independent learners as proposed by the new teaching and learning methodologies without the necessary foundation skills? The authors argue, based on international standards and benchmarking …

Mature Students - An Examination Of Dit’S Policy And Practice, Dáire Mag Cuill Nov 2003

Mature Students - An Examination Of Dit’S Policy And Practice, Dáire Mag Cuill

Articles

This paper examines the current position of mature students in the Technological University Dublin, the largest third-level institute in Ireland. It also deals with the treatment of mature applicants, and the position of mature students in the Republic of Ireland in general. The focus of the paper is on equity issues, and in all discussions of equity the underpinning principle is equality of opportunity. Where places on a third-level course are limited, for example, all applicants must be treated equally and the places allocated in a ‘fair’ manner. This does not mean that one cannot discriminate in the true sense …


Live And Let Die: Regulatory Mechanisms In Fas-Mediated Apoptosis, James Curtin, Thomas Cotter Nov 2003

Live And Let Die: Regulatory Mechanisms In Fas-Mediated Apoptosis, James Curtin, Thomas Cotter

Articles

Activation of Fas receptor by Fas ligand causes caspase 8 activation and apoptosis in cells and is an important mechanism by which normal tissue homeostasis and function are maintained. Activation of caspase 8 is preceded by the formation of a death-inducing signalling complex (DISC), and a number of redundant mechanisms regulate DISC formation in vivo. Fas receptor is widely expressed in tissues, and dysfunction of the regulatory mechanisms in Fas receptor signalling has been reported in several diseases including autoimmune disease and cancer. This review aims to identify and discuss the various mechanisms employed by cells to alter their sensitivity …


Defects In Death-Inducing Signalling Complex Formation Prevent Jnk Activation And Fas-Mediated Apoptosis In Du 145 Prostate Carcinoma Cells, James Curtin, Thomas Cotter Nov 2003

Defects In Death-Inducing Signalling Complex Formation Prevent Jnk Activation And Fas-Mediated Apoptosis In Du 145 Prostate Carcinoma Cells, James Curtin, Thomas Cotter

Articles

Androgen-independent prostate carcinomas are resistant to chemotherapy and cell lines derived from androgen-independent prostate carcinomas such as DU 145 cells are highly resistant to Fas-mediated apoptosis. The incubation of DU 145 cells with anti-Fas IgM agonistic antibody of Fas receptor fails to activate JNK, a stress kinase involved in regulating apoptosis. We have previously shown that JNK activation is sufficient and necessary to promote Fas-mediated apoptosis in DU 145 cells. We investigate the mechanisms by which JNK activation and apoptosis are abrogated. HSP27 is overexpressed in DU 145 cells and has previously been reported to sequester DAXX and prevent JNK …

A Two Phase Approach To Bayesian Network Model Selection And Comparison Between The Mdl And Dgm Scoring Heuristics, Michael Kane, Sahin Ferat, Andreas Savakis Oct 2003

A Two Phase Approach To Bayesian Network Model Selection And Comparison Between The Mdl And Dgm Scoring Heuristics, Michael Kane, Sahin Ferat, Andreas Savakis

Articles

This paper presents an efficient algorithm for learning a Bayesian belief network (BBN) structure from a database, as well as providing a comparison between two BBN structure fitness functions. A Bayesian belief network is a directed acyclic graph representing conditional expectations. In this paper, we propose a two-phase algorithm. The first phase uses asymptotically correct structure learning for efficient search space exploration, while the second phase uses greedy model selection for accurate search space exploration. The minimum description length (MDL) structure fitness function is also compared with the database given model probability (DGM) fitness function in the second phase. The …

Mwir And Lwir Spectral Signatures Of Water And Associated Materials, Herbert J. Mitchell, Carl Salvaggio Sep 2003

Mwir And Lwir Spectral Signatures Of Water And Associated Materials, Herbert J. Mitchell, Carl Salvaggio

Articles

Spectral infrared emissivity measurements have been made of a variety of materials both with and without surface water. The surface water was either natural, in the form of dew or residual rainwater, or artificially introduced by manual wetting. Materials naturally high in water content were also measured. Despite the rather diverse spectral population of the underlying materials, they exhibited very similar, featureless, water-like spectra; spectrally flat with a very high magnitude across the emissive infrared region. The implication to exploitation personnel that may use emissive infrared hyperspectral image data is that in areas where condensation is likely (e.g. high humidity) …


The Importance Of Background In The Detection And Identification Of Gas Plumes Using Emissive Infrared Hyperspectral Sensing, Herbert Mitchell, Gerard P. Jellison, David P. Miller, Carl Salvaggio, Craig J. Miller Sep 2003

The Importance Of Background In The Detection And Identification Of Gas Plumes Using Emissive Infrared Hyperspectral Sensing, Herbert Mitchell, Gerard P. Jellison, David P. Miller, Carl Salvaggio, Craig J. Miller

Articles

Using a Fourier transform infrared field spectrometer, spectral infrared radiance measurements were made of several generated gas plumes against both a uniform sky and terrestrial background. Background temperature, spectral complexity, and physical homogeneity each influenced the success of emissive infrared spectral sensing technology in detecting and identifying the presence of a gas plume and its component constituents. As expected, high temperature contrast and uniform backgrounds provided the best conditions for detectability and diagnostic identification. This report will summarize some of SITAC’s findings concerning plume detectability, including the importance of plume cooling, plumes in emission and absorption, the effects of optical …

Transition Probabilities In Kr Ii And Kr Iii Spectra, Stevan Djenize, Vladimir Milosavljevic, Milan S. Dimitrijevic

Articles

On the basis of the relative line intensity ratio (RLIR) method, transition probability values of the spontaneous emission (Einstein's A values) of 14 transitions in the singly (Kr II) and 7 transitions in doubly (Kr III) ionized krypton spectra have been obtained relatively to the reference A values related to the 435.548 nm Kr II and 324.569 nm Kr III, the most intensive transitions in the Kr II and Kr III spectra. Our Kr III transition probability values are the first data obtained experimentally using the RLIR method. A linear, low–pressure, pulsed arc operated in krypton discharge was used as …
