Fire Detection System using Faster R-CNN (2017)

Various fire detection systems have been constructed to prevent disastrous fire. However, existing fire detection systems are limited to practical applications due to lower detection accuracy and frequent alerts caused by incorrect operations. Previous fire detection systems have only focused on detecting flames. Therefore they can mistake the flames of candles or gas ranges as a fire. They also cannot provide additional life-saving information, such as the location of people or fire extinguishers. Thus, we have tried to construct a new fire detection system which can improve flame detection accuracy, does not incorrectly identify the flame of candles or gas ranges as a fire, and also provide additional lifesaving information. Faster R-CNN is a deep learning algorithm that detects classes and locations of objects, as well as fires, in real-time by using CNN. We have built our fire detection system based on Faster R-CNN. In order to evaluate the performance of our fire detection system, we used various images such as forest fires, gas range fires, and candle flames. Consequently, the fire detection rate of our system was very good at 99.24%. In addition, we analyzed its object detection performance involving 14 classes, such as people, fire extinguishers, doors, pets, etc. Finally, the mAP (mean Average Precision) was relatively high at 0.7863.
Visual User Interfaces for Information Exploration (1998)

The next generation of database management, directory browsing, information retrieval, hypermedia, scientific data management, and library systems can enable convenient exploration of growing information spaces by a wider range of users. User interface designers can provide more powerful search techniques, more comprehensible query facilities, better presentation methods, and smoother integration of technology with task. This paper offers novel graphical and direct manipulation approaches to query formulation and information presentation/manipulation. These approaches include a graphical approach to restricted boolean query formulation based on generalization/aggregation hierarchies, a filter/flow metaphor for complete boolean expressions, dynamic query methods with continuous visual presentation of results as the query is changed (possibly employing parallel computation), and color-coded 2-dimensional space-filling tree-maps that present multiple-level hierarchies in a single display (hundreds of directories and more than a thousand files can be seen at once).

Theoretical analysis of alternative splice forms using computationalmethods (2002)

Nowadays understanding alternative splicing is one of the greatest challenges in biology, because it is a genetic process much more important than thought at the time of its discovery. In this paper, we explain the approach of using the different available databases and software tools to start a large scale investigation of alternative splice forms. To collect information about alternative splicing we investigated known data in the databases using different computational methods. The investigations proceeded from the genomic sequence data to structural protein data. Then, we interpreted those data to find the relationship between alternative splice forms and protein function and structure. We found some interesting features of alternative splicing which are presented here. We discuss the results of one chosen example. They concern the coverage quality of the protein sequence of a known structure, an EST analysis, the validation of splice variants, the determination of the alternative splice type, and finally the link between alternative splicing and disease.
LASSO-Patternsearch algorithm with application to ophthalmology and genomic data (2008)

The LASSO-Patternsearch algorithm is proposed to efficiently identify patterns of multiple dichotomous risk factors for outcomes of interest in demographic and genomic studies. The patterns considered are those that arise naturally from the log linear expansion of the multivariate Bernoulli density. The method is designed for the case where there is a possibly very large number of candidate patterns but it is believed that only a relatively small number are important. A LASSO is used to greatly reduce the number of candidate patterns, using a novel computational algorithm that can handle an extremely large number of unknowns simultaneously. The patterns surviving the LASSO are further pruned in the framework of (parametric) generalized linear models. A novel tuning procedure based on the GACV for Bernoulli outcomes, modified to act as a model selector, is used at both steps. We applied the method to myopia data from the population-based Beaver Dam Eye Study, exposing physiologically interesting interacting risk factors. We then applied the the method to data from a generative model of Rheumatoid Arthritis based on Problem 3 from the Genetic Analysis Workshop 15, successfully demonstrating its potential to efficiently recover higher order patterns from attribute vectors of length typical of genomic studies.
Sensory/motor therapy for the treatment of oral dyskinesia. A new approach to the treatment of oromyofunctional disorders with the use of tactile cuing handheld exercisers. (1995)

Persons with oral myofunctional disorders suffer from multiple risk factors for impairments. A craniofacial malformation may be responsible for both behavioral as well as structural modifications. This includes the effect of appearance on self concept and behavior (Case, 1988). Structural modifications as well as negative oral habits include: an open mouth resting posture; mouth breathing; low forward tongue carriage; forward articulatory tongue placement (linguadental/lingua alveolar); abnormal lip, tongue and facial muscle movements during swallowing; reduced upper lip length and mobility; overcontraction of the mentalis muscle; negative habits such as nailbiting, thumb or finger-sucking, lip biting, and lip licking (Hale and Kellum, 1988). Clinical observations also include hypotonicity of the posterior oral musculature during swallowing activity. The purpose of this article is to explore the etiology of oral myofunctional disorders and present a new approach to treatment using functional prosthetic therapy.
A Simple Synthetic Method of <i>trans</i>-5-Aryl and 5-Cyclopropyl Derivatives of 2-Isoxazolin-4-ol via Intramolecular Ring Opening of α,β-Epoxy Ketone Oximes (1990)

Abstract trans-5-Aryl and 5-cyclopropyl derivatives of 2-isoxazolin-4-ol were conveniently prepared from trans-2-aryl- and 2-cyclopropyl-3-benzoyloxiranes and hydroxylamine hydrochloride in the presence of pyridine via an intramolecular opening of oxirane by the oxygen nucleophile of the oxyimino group.
A Neural Network Model of Naive Preference and Filial Imprinting in the Domestic Chick (1997)

Filial imprinting in domestic chicks is of interest in psychology, biology, and computational modeling because it exemplifies simple, rapid, in-nately programmed learning which is biased toward learning about some objects. Hom et al. have recently discovered a naive visual preference for heads and necks which develops over the course of the first three days of life. The neurological basis of this predisposition is almost en-tirely unknown; that of imprinting-related learning is fairly clear. This project is the first model of the predisposition consistent with what is known about learning in imprinting. The model develops the predisposi-tion appropriately, learns to &quot;approach &quot; a training object, and replicates one interaction between the two processes. Future work will replicate more interactions between imprinting and the predisposition in chicks, and analyze why the system works. 1
Pathogenesis of Hyperglycemia in Genetically Obese-Hyperglycemic Rats, Wistar Fatty: Presence of Hepatic Insulin Resistance. (1989)

The present studies were designed to clarify the contribution of the liver to the development of hyperglycemia in Wistar fatty rats. The hepatic activities of insulin-inducible enzymes involved in glycolysis (glucokinase; GK and pyruvate kinase) and lipogenesis (glucose-6-phosphate dehydrogenase), were higher in fatty rats than in lean rats at 4 and 8 weeks of age because of the higher insulin levels in the former. Thereafter, the GK activities of fatty rats decreased slightly in spite of severe hyperinsulinemia, and did not differ from those of lean rats. In addition, fatty rats had higher levels of insulin-suppressible gluconeogenic enzymes, glucose-6-phosphatase (G6Pase) and fructose-1, 6-diphosphatase. These findings indicate that the hepatic enzymes of fatty rats are resistant to insulin. This postulation was supported by the fact that the hepatic enzyme activities of fatty rats showed a lower response to changes in plasma insulin levels produced by fasting and refeeding. The G6Pase/GK ratio, which indicates net glucose handling in the liver, increased in fatty rats and decreased in lean rats with advancing age, suggesting that hepatic glucose production in fatty rats becomes dominant with advancing age. The changes in hepatic glycolytic intermediates supported this suggestion; the glycolytic steps both from glucose to glucose-6-phosphate and from phospho-enolpyruvate to pyruvate in fatty rats were accelerated at 5 weeks of age, but suppressed at 12 weeks of age. These results indicate that insulin resistance in the hepatic enzyme regulation may contribute to the development of hyperglycemia in Wistar fatty rats.
Loss correlation for queues with bursty input streams (2003)

The authors evaluate and characterize the correlation between packet losses for two queuing systems in discrete time that are motivated by broadband ISDN (BISDN) applications. The first, a two-class discrete-time queuing system, approximates the output queue of an asynchronous transfer mode (ATM) switch. The queue serves periodic foreground traffic and random background traffic. The background traffic is modeled as independently identically distributed batches of arbitrary distribution. It is shown that the conditional loss probability (CLP) is independent if the buffer size is at least as large as the period of the foreground traffic. Example calculations indicate that losses occur essentially randomly as long as the foreground traffic uses less than 10% of the channel capacity. The second analysis derives the CLP seen by a selected stream in a slotted finite-buffer system with a superposition of interrupted Poisson sources. Here, the total number of arrivals may be correlated from slot to slot. Traffic correlation is seen to have a strong influence on loss correlation, while buffer size is seen to have virtually none.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

COHERENT OPTICAL DETECTION OF ULTRASONIC IMAGES USING ELECTRONIC SCANNING (1970)

Visualization of ultrasonic wavefields incident on an optically reflecting surface is effected by coherent optical detection of the deformations of this surface. A Twyman-Green interferometer is used in which the orthogonal reference beam is frequency-offset with an ultrasonic light modulator. The recombined light field is scanned with an image dissector, and the resulting image displayed on a kinescope.
Method for merging multiple exposure color image data (2009)

In most of nowadays intelligent systems (robots, vehicles, etc.) the sensing based on image processing represents an essential part. In order to be able to use these systems effectively even if the lighting conditions are not ideal, e.g. dark objects, very bright areas in the scene, etc., multiple exposure based image reproduction algorithms are highly welcome. The main aim of the paper is to introduce a novel method enabling to merge multiple exposure images and obtain a corresponding High Dynamic Range Image.
Constraining the Complexity of Stimulated Reservoir Volume during Multi-Stage Hydraulic Fracturing of Horizontal Wells through Inter-Well Pressure Hit Modeling (2017)

Abstract To determine the degree of connectivity and complexity of a stimulated fracture network, a prescriptive completion program was undertaken in the Horn River Shale Basin which enabled continuous monitoring of pressure interactions among horizontal wells during multi-stage hydraulic fracturing. This paper introduces a novel approach to characterize the stimulated fracture network, and consequently, to optimize the stimulation, wellbore placement, and re-fracturing designs, by integrating the pressure hits captured from passive wellbores on a pad during fracturing operations. If effective, it may also provide a cost-effective alternative to microseismic monitoring. The workflow initially considers a rigorous data analysis on available pressure hits at each frac-stage in time and space, including the location of pressure events, time of flights to offsetting stimulation, and the magnitude and intensity of pressure hits/falloffs. Streamline simulation, assisted with a hydraulic fracturing module, is then used to match the pressure hits/falloffs in the passive wells. This ultimately provides a dynamic probabilistic 3D map of the fracture network growth, reservoir complexity and inter-well connectivity. The fundamental mechanisms of hydraulic fracturing and the interactions across natural and induced fractures (fracture initiation/propagation/growth) are implemented by means of an advanced coupled hydro-mechanical code, based on distinct element method. Results from initial data analyses were fed into a hydro-mechanical model, which incorporated the physics of the hydraulic fracturing process, in order to reproduce the pressure hit signatures. An assisted streamline-based technique was used to simulate various scenarios of pressure hit responses to construct a database of standard pressure hit/falloff patterns. This database, compiled into a dynamic 3D map, facilitated a probabilistic approach to calculate a robust estimate range of stimulated fracture network of the pad area. This database can be subsequently used in future stimulation and re-fracturing designs. The backbone of the highly complex fracture network, extracted from pressure hit/falloff data, was found to closely align with high-resolution microseismic data. Calibration of the hydro-mechanical model using the pressure hit data provides increased confidence in the use of the model to optimize well placement and hydraulic fracturing designs. In the absence of microseismic data, this unique workflow has the potential to deliver real-time on-site monitoring of fracturing operation at a reduced cost and acceptable accuracy, to provide additional statistics on complexity of stimulated reservoir volume, and to offer a better assessment of the likely range of the induced fracture network among horizontal wells.
Traitement du signal audio dans le domaine codé : techniques et applications. (2001)

La manipulation classique de flux audio codes necessite une operation prealable de decodage pour extraire les signaux temporels puis de recodage apres traitement. Pour pallier les inconvenients en terme de complexite et delai algorithmiques, lies a cette methode, cette these se propose de realiser un traitement direct dans le domaine code. On s'interesse aux codeurs de types frequentiel perceptuel et particulierement mpeg-1 layer i-ii et tdac de ftr&d. Le contexte applicatif illustre concerne le traitement du son pour la teleconference multipoint. Le premier traitement aborde concerne le filtrage dans le domaine des sous-bandes. Une methode generique a ete developpee permettant de transposer tout filtre rationnel (fir ou iir) temporel dans ce domaine et pour tout banc de filtres a decimation maximale assurant la reconstruction parfaite. Cette methode a ete appliquee a la spatialisation sonore par des filtres hrtf dans le domaine des sous-bandes. L'etude de la sommation sur les flux codes souleve plusieurs contraintes suivant le codeur considere. Pour le codeur mpeg-1, la problematique principale concerne la determination des parametres psychoacoustiques necessaires a l'allocation de bits. L'algorithme propose apporte donc une solution a ce probleme par estimation des seuils de masquage des signaux individuels a sommer puis recombinaison. Une methode de reduction de debit est aussi derivee a partir de cet algorithme. Pour le codeur tdac la diminution de la complexite dans le procede de sommation repose sur le phenomene de masquage inter-signaux en tenant compte de la structure particuliere de ce codeur. Elle profite de l'imbrication des dictionnaires de la quantification vectorielle qu'il utilise. La mise en valeur de l'interet du traitement dans le domaine code a ete concretisee par une mise en œuvre dans un pont audio de teleconference multipoints qui assure les fonctionnalites de mixage, correction de trames effacees et la gestion des flux discontinus.
Effect of IL‐4 and IL‐13 on collagen production in cultured LI90 human hepatic stellate cells (2005)

Our data suggested that IL-4 and IL-13 directly affected HSCs by increasing collagen production and suppressing cell proliferation. The anti-fibrogenetic effect of IFN may be due in part to the blockade of IL-4 and IL-13 stimulation of HSCs.
ACE Inhibition with Captopril Retards the Development of Signs of Neurodegeneration in an Animal Model of Alzheimer’s Disease (2013)

Increased generation of reactive oxygen species (ROS) is a significant pathological feature in the brains of patients with Alzheimer's disease (AD). Experimental evidence indicates that inhibition of brain ROS could be beneficial in slowing the neurodegenerative process triggered by amyloid-beta (Abeta) aggregates. The angiotensin II AT1 receptor is a significant source of brain ROS, and AD patients have an increased brain angiotensin-converting enzyme (ACE) level, which could account for an excessive angiotensin-dependent AT1-induced ROS generation. Therefore, we analyzed the impact of ACE inhibition on signs of neurodegeneration of aged Tg2576 mice as a transgenic animal model of AD. Whole genome microarray gene expression profiling and biochemical analyses demonstrated that the centrally active ACE inhibitor captopril normalized the excessive hippocampal ACE activity of AD mice. Concomitantly, the development of signs of neurodegeneration was retarded by six months of captopril treatment. The neuroprotective profile triggered by captopril was accompanied by reduced amyloidogenic processing of the amyloid precursor protein (APP), and decreased hippocampal ROS, which is known to enhance Abeta generation by increased activation of beta- and gamma-secretases. Taken together, our data present strong evidence that ACE inhibition with a widely used cardiovascular drug could interfere with Abeta-dependent neurodegeneration.
An Image Retrieval Technique in JPEG Compressed Domain (2006)

Most images are now stored and transferred in the compressed form, of which JPEG format turns even more popular. However, it takes much time to decode the JPEG images fully while indexing them. This paper proposes a fast image retrieval technique in JPEG compressed domain. It extracts key information from the important DCT(Discrete Cosine Transform) coefficients of the image and gains the feature vectors through calculating.These feature vectors can be compared with those from the target image so that the differences between them can be found. In this way, images that have relatively small differences with the target are to be the output. This technique makes the indexing time shorter and the precision of matching higher.
Shaping organisms with apoptosis (2013)

Programmed cell death is an important process during development that serves to remove superfluous cells and tissues, such as larval organs during metamorphosis, supernumerary cells during nervous system development, muscle patterning and cardiac morphogenesis. Different kinds of cell death have been observed and were originally classified based on distinct morphological features: (1) type I programmed cell death (PCD) or apoptosis is recognized by cell rounding, DNA fragmentation, externalization of phosphatidyl serine, caspase activation and the absence of inflammatory reaction, (2) type II PCD or autophagy is characterized by the presence of large vacuoles and the fact that cells can recover until very late in the process and (3) necrosis is associated with an uncontrolled release of the intracellular content after cell swelling and rupture of the membrane, which commonly induces an inflammatory response. In this review, we will focus exclusively on developmental cell death by apoptosis and its role in tissue remodeling.
Molecular Diagnosis of <i>Mycoplasma pneumoniae</i> Respiratory Tract Infections (2003)

Mycoplasma pneumoniae is responsible for 10 to 20% of the cases of community-acquired pneumonia and has been associated with acute exacerbations of asthma ([22][1]). M. pneumoniae is also implicated in mild acute respiratory infections, such as sore throat, pharyngitis, rhinitis, and
All-optical programmable <scp>AND</scp> gate implementation in a germanium-doped silica planar waveguide (1995)

We report the results of an all-optical programmable AND logic gate. This gate consists of a germanium-doped silica planar waveguide, a laser, and the means of coupling two fundamental frequency beams into different guiding modes of the waveguide along with a second harmonic beam coupled into one guiding mode. These waves interfere in the film generating a set of semipermanent second-order susceptibility gratings which give rise to the waveguide, the film-generated second harmonic light wave made to behave as an output of a logic AND gate. The fundamental and second harmonic light were sent into the waveguide during the programming sequence, but only the fundamental light was injected to probe the logic gate to produce an output. The measured signal-to-noise ratio was 17 dB.
