Compression of SMIL documents (2002)

Summary form only given. The World Wide Web Consortium (W3C) standard synchronized multimedia integration language (SMIL) is an HTML-like mark-up language to describe temporal behavior and presentation layout for multimedia objects. SMIL is widely used in today's Internet. Many video clips send SMIL documents to clients before transmitting video and audio streams. Data compression is a process to reduce the number of bits in a representation of data. It can save storage space and reduce bandwidth requirement. Data compression technologies may be classified into two categories: lossless and lossy. The compression technology that can recover data perfectly from the compressed bits is called lossless compression. The one that cannot is called lossy compression. There are many lossless data compression algorithms, such as Ziv-Lempel methods, that have been developed in recent years. However, SMIL document compression performance with such methods is not very impressive because they do not exploit the special format of the SMIL document. As a result, the rate to compress a SMIL document is almost the same as that to compress English text, i.e., 2-4 bits/char. For better compression, a method based on a new parsing technology is proposed. The proposed compression algorithm contains two major procedures: parsing and coding. Parsing is a procedure to segment a SMIL document into non-overlapping phrases (a string of consecutive characters). Coding is a procedure to assign a codeword to the phrase. Both the phrase and codeword are of variable length.
Automatic optical-loss compensation with Er-doped fibre amplifier (1991)

Optical losses ranging over 15 dB are automatically offset (for signal frequencies ̃ 1540 to 1553 nm) with an Er-doped fibre amplifier used in a feedback configuration. This technique can recover local optical loss while preserving phase information, and is applicable to scale-factor stabilisation in interferometric fibre sensors.
New Treatments Substantially Increase LOT/FIT Pressures to Solve Deep HTHP Drilling Challenges (2001)

Abstract Insufficient borehole pressure integrity (BHPI) is a major drilling challenge in deep, high-temperature, high-pressure (HTHP) wells in California and other areas. Shale and sandstone formations with low BHPI may be weakened by leaking faults/ fractures or poor rock properties, causing lost returns with mud weights close to pore pressures. Drilling through depleted or low pore pressure formations with some probability of drilling into higher pressured zones in the same hole section compounds the severity of this challenge in the Temblor formation in Kern County, California. This challenge was solved by an innovative treatment applied in the Berkley East Lost Hills No. 1 well. Compared to conventional methods, it increased leakoff test (LOT) and formation-integrity test (FIT) pressures to incremental values higher than those typically seen in the industry. Increasing BHPI allowed an additional 960 ft to be drilled before a 7-in. liner was set, and the well was drilled to 19,724 ft. This depth met the objective of the well (to obtain full penetration through the objective sands) and allowed the subsequent discovery of a pay zone. If the new treatment to increase the LOT had not been used, the 7-in. liner would have been set early, and it is unlikely that the discovery zone would have been penetrated. Preventing skin and formation damage in potential zones of interest while treating weak points was another major concern heightened by a wide range of pore pressures. This paper discusses a theoretical mechanism to help explain how the treatment rapidly and substantially increases pressure integrity across both sand and shale formations. Minor penetrations in high and low-permeability sandstone-core tests help explain why the treatment system minimizes or prevents skin damage. Skin damage in the zones of interest may be prevented or minimized by BHPI treatments that only enter leaking fractures or faults. Further development and deployment of BHPI treatment technology promises a step-change in industry practice to optimize well plans with lower cost programs for drilling fluids, casing design, cementing, and completion equipment. Optimized well designs should reduce both drilling days and flat time by allowing operators to drill smaller-diameter holes while using fewer casing strings to achieve the same production-string dimensions.

Partially Reliable-Concurrent Multipath Transfer (PR-CMT) for Multihomed Networks (2008)

In this paper, we proposed a partially reliable - concurrent multipath transfer (PR-CMT) that is featured with partially reliable multi-path transmission based on the concurrent multipath transfer (CMT) and the stream control transmission protocol partial reliability extension (PR-SCTP). The proposed partially reliable transmission is realized by the "timed reliable service". Data in PR-CMT are associated with lifetime. When the lifetime of the data is expired, PR-CMT would not transmit and retransmit the expired data. The false acked TSNs problem is identified in PR-SCTP and CMT. In this paper, the proposed PR-CMT can adopt some mechanisms to eliminate the false acked transmission sequence numbers (TSNs) problem. Simulation results show that PR-CMT can (i) have better transmission efficiency and (ii) consume less bandwidth.
SpeechFind: advances in spoken document retrieval for a National Gallery of the Spoken Word (2005)

Advances in formulating spoken document retrieval for a new National Gallery of the Spoken Word (NGSW) are addressed. NGSW is the first large-scale repository of its kind, consisting of speeches, news broadcasts, and recordings from the 20th century. After presenting an overview of the audio stream content of the NGSW, with sample audio files from U.S. Presidents from 1893 to the present, an overall system diagram is proposed with a discussion of critical tasks associated with effective audio information retrieval. These include advanced audio segmentation, speech recognition model adaptation for acoustic background noise and speaker variability, and information retrieval using natural language processing for text query requests that include document and query expansion. For segmentation, a new evaluation criterion entitled fused error score (FES) is proposed, followed by application of the CompSeg segmentation scheme on DARPA Hub4 Broadcast News (30.5% relative improvement in FES) and NGSW data. Transcript generation is demonstrated for a six-decade portion of the NGSW corpus. Novel model adaptation using structure maximum likelihood eigenspace mapping shows a relative 21.7% improvement. Issues regarding copyright assessment and metadata construction are also addressed for the purposes of a sustainable audio collection of this magnitude. Advanced parameter-embedded watermarking is proposed with evaluations showing robustness to correlated noise attacks. Our experimental online system entitled "SpeechFind" is presented, which allows for audio retrieval from a portion of the NGSW corpus. Finally, a number of research challenges such as language modeling and lexicon for changing time periods, speaker trait and identification tracking, as well as new directions, are discussed in order to address the overall task of robust phrase searching in unrestricted audio corpora.

3-D prestack depth migration in anisotropic media: A case study at the Lodgepole reef play in North Dakota (2001)

A key problem in interpreting depth-migrated sections (prestack or poststack) is that seismic horizons almost never agree with well tops. Often, seismic events are on the order of 1000 ft deeper. Seismic anisotropy is mostly blamed for the discrepancy. In this paper, we show a case study at the Lodgepole reef play in North Dakota where, by incorporating strong seismic anisotropy in a 3-D velocity model, we can achieve good depth migration results and excellent well ties (within 50 ft). Our estimate of anisotropy parameters agrees with laboratory measurements on core samples.

Biomodification of Rubberized Asphalt and Its High Temperature Properties (2015)

Asphalt rubber has been commonly used in the United States for modifying asphalt binder. There have been several studies on improving the interaction and adhesion between rubber and asphalt matrix. The modification of asphalt binder with crumb rubber (CR) is mainly controlled by the exchange equilibrium between components of asphalt binder and CR. This phenomenon increases the size of rubber particles (swelling) up to three times their original size and leads to a significant increase in the viscosity of the resulting asphalt. Swelling and increased viscosity not only promote separation of the modified matrix into two distinguishable phases but also increase the difficulty of pumping and application of rubberized asphalt. This study investigated the effectiveness of treating rubber with an amide-enriched biomodifier to facilitate breakage of disulfide bonds in rubber polymer while promoting interactions between free radicals and amide groups of biomodifier. Promoting interactions between rubber polymer and asphalt aromatic compounds by adding a biomodifier could alleviate phase separation while enhancing overall matrix elasticity. This modification enhanced the rheological properties of rubberized asphalt, including high-temperature properties as well as its palpability. The rotational viscometer and dynamic shear rheometer were used to evaluate the effect of biomodifier on the rheological properties of asphalt rubber at high and intermediate temperatures. Fourier transform infrared spectroscopy was used to examine the presence of rubber polymer compounds inside the asphalt matrix. The results showed that introduction of biomodifier facilitated the application of higher CR percentages while improving the overall rheological properties of the asphalt rubber.
Noncatalytic organic rearrangement using supercritical water (2001)

Abstract Significant acceleration of Beckmam and pinacol rearrangements can be achieved by using supercritical water (scH2O), especially just near the critical point even in the absence of any acid catalysts. A high-pressure, high-temperature flow reactor system with FTlR operable at 500°C and 50 MPa was suaxssfdy developed, wherein the non-catalytic Beckmam and pinacol rearrangements using scH2O were carried out and monitored. It has been demonstrated that scH20 itself acts very effectively in the place of conventional acid catalysts for both the rearrangements. The rate of the pinacol rearrangement using scH2O is 28,200-fold rate of that in 0.871 M HCl solution at 46.7 MPa under distillation conditions. The high rate of reaction may be attributed to a great increase in the local proton concentration around the organic reactants.
APE: A Data-Driven, Behavioral Model-Based Anti-Poaching Engine (2015)

We consider the problem of protecting a set of animals such as rhinos and elephants in a game park using D drones and R ranger patrols (on the ground) with R ≥ D. Using two years of data about animal movements in a game park, we propose the probabilistic spatio-temporal graph (pSTG) model of animal movement behaviors and show how we can learn it from the movement data. Using 17 months of data about poacher behavior, we also learn the probability that a region in the game park will be targeted by poachers. We formalize the anti-poaching problem as that of finding a coordinated route for the drones and ranger patrols that maximize the expected number of animals that are protected, given these two models as input and show that it is NP-complete. Because of this, we fine tune classical local search and genetic algorithms to the case of anti-poaching by taking specific advantage of the nature of the anti-poaching problem and its objective function. We develop a measure of the quality of an algorithm to route the drones and ranger patrols called “improvement ratio.” We develop a dynamic programming based APE_Coord_Route algorithm and show that it performs very well in practice, achieving an improvement ratio over 90%.
Multiple Relational Embedding (2004)

We describe a way of using multiple different types of similarity rela-tionship to learn a low-dimensional embedding of a dataset. Our method chooses different, possibly overlapping representations of similarity by individually reweighting the dimensions of a common underlying latent space. When applied to a single similarity relation that is based on Eu-clidean distances between the input data points, the method reduces to simple dimensionality reduction. If additional information is available about the dataset or about subsets of it, we can use this information to clean up or otherwise improve the embedding. We demonstrate the po-tential usefulness of this form of semi-supervised dimensionality reduc-tion on some simple examples. 1

Citrus Responses to <i>Xylella fastidiosa</i> Infection (2012)

The xylem-limited bacterium Xylella fastidosa causes the widely disseminated citrus variegated chlorosis disease (CVC). In Brazil, CVC has been known for more than 20 years and affects only sweet orange. Lime and mandarin have remained free of symptoms despite the high inoculum pressure. Knowing the mechanisms underlying this apparent resistance is important to devise new disease control strategies. The reaction of commercial sweet orange ('Caipira', 'Natal', 'Pêra', and 'Valencia'), lime (Mexican and Persian), mandarin ('Cleopatra', 'Cravo', 'Ponkan', and 'Sunki'), and the acid citrus species Rangpur to X. fastidiosa was compared in artificially inoculated seedlings, which were assessed for symptom expression, pathogen isolation, and the amount of apparently occluded xylem vessels in cross-sectioned leaf petioles. Only the sweet orange expressed typical CVC symptoms, varying from 53.8% in Valencia to 63.0% in Caipira. Average percentages of positive isolations (pi) and occluded vessels (ov) were higher in sweet orange (pi= 59.2 to 75.0; ov = 10.7 to 25.8) than mandarin (pi = 2.3 to 16.3; ov = 1.4 to 4.0), lime (pi = 0 to 5.4; ov = 0 to 2.1), or Rangpur (pi = 1,9; ov = 1.1). There were no obvious differences in xylem anatomy among all citrus varieties, suggesting that the mechanisms of resistance to CVC are not related to any physical variation in xylem structure.
Offset vector tile gather extension and weighting to reduce footprint in dual-datum and converted-wave migration (2015)

The latter allows post-migration processing such as Radon demultiple or azimuthal residual moveout flattening to enhance the quality of the final stacked image. Single fold coverage enables each COV volume to produce a clean image with limited migration-operator artefacts, and with the potential to preserve the AVO character. However, in the COV domain, this works only for surveys with sources and receivers on the same acquisition datum and with a single-mode arrival having symmetric ray paths in a flat earth (such as P-waves). Irregular subsurface illumination for dual-datum acquisition or mode-converted PS-wave data causes artefacts in migration of COV binned data, including acquisition footprints. Here we describe a technique to reduce these artefacts. The method bins recorded data into gathers corresponding to each offset vector tile (OVT) and computes time and velocity-model dependent weighting and muting functions for each OVT gather in such a way that uniform illumination is obtained at all levels beneath a reference level.

Congestion aware priority flow control in data center networks (2016)

The data center bridging (DCB) protocols enable Ethernet to become the leading unified fabric for a converged data center. As a part of DCB, priority flow control (PFC) is a control mechanism that provides the losslessness feature required by certain applications such as Fibre Channel over Ethernet. Quantized congestion notification (QCN) is also a DCB protocol and provides congestion control functionality to complement PFC. However, in today's practical data center networks, QCN is not feasible and PFC is not efficient against congestion. We propose a new link layer mechanism called congestion aware priority flow control (CaPFC) that equips PFC with better congestion control capability in the absence of QCN. Changes brought by CaPFC on top of PFC are lightweight. By conducting simulations in NS-3, we demonstrate that CaPFC handles persistent and flash congestion much better than PFC. For the short messaging traffic and the query traffic, which are sensitive to tail latencies, CaPFC consistently outperforms PFC in terms of tail flow completion time.
