Interactive web crawling and data extraction (2018)

Title: Interactive crawling and data extraction Author: Bc. Petr Fejfar Author's e-mail address: pfejfar@gmail.com Department: Department of Distributed and Dependable Systems Supervisor: Mgr. Pavel Je ek, Ph.D., Department of Distributed and De- pendable Systems Abstract: The subject of this thesis is Web crawling and data extraction from Rich Internet Applications (RIA). The thesis starts with analysis of modern Web pages along with techniques used for crawling and data extraction. Based on this analysis, we designed a tool which crawls RIAs according to the instructions defined by the user via graphic interface. In contrast with other currently popular tools for RIAs, our solution is targeted at users with no programming experience, including business and analyst users. The designed solution itself is implemented in form of RIA, using the Web- Driver protocol to automate multiple browsers according to user-defined instructions. Our tool allows the user to inspect browser sessions by dis- playing pages that are being crawled simultaneously. This feature enables the user to troubleshoot the crawlers. The outcome of this thesis is a fully design and implemented tool enabling business user to extract data from the RIAs. This opens new opportunities for this type of user to collect data from Web pages for use...
Flip chip CPU package technology at Intel: a technology and manufacturing overview (2003)

CPU evolution in performance/cost continues to drive the packaging technology. The limitations of wire bonded interconnects and traditional C4/Ceramic flip chip have resulted in development of a new paradigm for CPU packaging involving area array solder bump connections to a high density organic multi layer LGA package. This paper describes some of the key reasons behind this transition. It introduces the key aspects of the new assembly process architecture, associated process flows and key yield/reliability issues addressed during the development.
Hoveyda‐Type Olefin Metathesis Complexes (2014)

This chapter summarizes the work in ruthenium-based olefin metathesis catalyst design, using the chelating benzylidene ligands-that is, Hoveyda-Grubbs type catalysts bearing oxygen and other chelating heteroatoms. It discussess the properties of olefin metathesis catalysts, one cannot disregard the mechanistic studies that were carried out for the chelated benzylidene complexes. The chapter describes the complexes based on the ubiquitous isopropoxy-benzylidene chelating ligand (derived from 2-isopropoxystyrene) with different N-heterocyclic carbene (NHC) groups and their activity in olefin metathesis catalysis. Changes on the classical mesitylene substituted Arduengo NHC may be classified into three main types such as changing the main imidazoline ring, substitutions on the ring backbone, and functionalization of the aromatic moieties bound to the nitrogen atoms. The discovery that anionic ligands freely interchange during the reaction has some serious implications when planning new olefin metathesis catalysts.
<title>Holographic Rotman lens for phased-array antenna beam forming</title> (1995)

This paper introduces an optical implementation of the classic Rotman lens beamformer for use in ultra-wideband array antenna beamforming applications. The optical version described here features volume holograms as lens ports, arranged on geometric contours which follow modified Rotman's lens design equations. Modification of Rotman's lens equations, modeling of ray propagation in the lens, and the design process for this holographic Rotman lens are described in detail. Currently, a free-space experiment is in process to validate this design at 10 GHz, and to provide insight on the use of diffractive optics technology for millimeter-wave applications. Experimental results will be reported in detail in the near future.

Non-gaussian robust matched subspace detectors and signal design analysis for a class of separable subspaces (2005)

The paper introduces a new class of subspaces, denoted separable subspaces, that enables the derivation of computationally efficient expressions for robust matched filter detectors for the family of generalized Gaussian (GG) density functions. These generalized likelihood ratio detectors are robust to interference whose subspace may or may not be known or learned. The detectors are generalizations of the /spl chi//sup 2/ and t or F statistics used when the noise is assumed to have a Gaussian density, also a member of the GG family. The paper also describes how arbitrary subspaces can be approximated by the newly introduced separable ones should it be advantageous to do so; separable subspaces therefore make it possible to discretize the space. The computationally efficient expressions for the detectors enable the performance analysis for signal design when the basis for the separable subspaces consist solely of binary valued elements. This class, which includes the Haar basis functions, has been shown to be applicable to functional MRI detection problems.
Genetic algorithm search of multiresolution tree with applications in data compression (1994)

Wavelet decomposition of data has been used with success for data compression in a large class of signals. The wavelet packets representation is a decomposition that includes as a special case the wavelet transform. In this scheme, wavelet packets are assembled as a representation of the signal. There exist a large number of possible wavelet combinations for each signal. An adaptation scheme based on the genetic optimization method is presented for determining an optimal representation for data compression. Experiment results using real data as well as autoregressive random processes are used to compare the performance of the adapted packets and the wavelet transform.
Characteristics of Bismuth Layered SrBi<sub>2</sub>Ta<sub>2</sub>O<sub>9</sub> Thin-Film Capacitors and Comparison with Pb(Zr, Ti)O<sub>3</sub> (1995)

We have developed the series of thin-film bismuth layer structured ferroelectric (BLSF) materials such as SrBi 2 Ta 2 O 9 , SrBi 2 Nb 2 O 9 , SrBi 4 Ti 4 O 15 and their solid solutions using metallo-organic-decomposition (MOD) spin-on coating techniques. We found that SrBi 2 Ta 2 O 9 is one of the best potential candidate materials for ferroelectric nonvolatile memories. The SrBi 2 Ta 2 O 9 thin-film capacitor had the remanent polarization ( P r+ - P r- ) of 20 µ C/cm 2 , coercive field of 35 kV/cm and dielectric constant of 250. SrBi 2 Ta 2 O 9 thin film on platinum electrode has fatigue-free characteristics for up to 2×10 11 cycles without requiring any complicated electrode system such as conductive oxide. Moreover, SrBi 2 Ta 2 O 9 thin film has many advantages, e.g. , high signal/noise ratio of 8 at 1.2 V, low-voltage operation at as low as 1 V, long data-retention, little surface effect, superior imprint properties and low leakage current. We considered that these advantages are due to (1) less space charge and (2) the inherent domain motion.

Soil moisture retrieval through a merging of multi-temporal L-band SAR data and hydrologic modelling (2009)

Abstract. The objective of the study is to investigate the potential of retrieving superficial soil moisture content (mv) from multi-temporal L-band synthetic aperture radar (SAR) data and hydrologic modelling. The study focuses on assessing the performances of an L-band SAR retrieval algorithm intended for agricultural areas and for watershed spatial scales (e.g. from 100 to 10 000 km2). The algorithm transforms temporal series of L-band SAR data into soil moisture contents by using a constrained minimization technique integrating a priori information on soil parameters. The rationale of the approach consists of exploiting soil moisture predictions, obtained at coarse spatial resolution (e.g. 15–30 km2) by point scale hydrologic models (or by simplified estimators), as a priori information for the SAR retrieval algorithm that provides soil moisture maps at high spatial resolution (e.g. 0.01 km2). In the present form, the retrieval algorithm applies to cereal fields and has been assessed on simulated and experimental data. The latter were acquired by the airborne E-SAR system during the AgriSAR campaign carried out over the Demmin site (Northern Germany) in 2006. Results indicate that the retrieval algorithm always improves the a priori information on soil moisture content though the improvement may be marginal when the accuracy of prior mv estimates is better than 5%.
Simulation of Machine-Specific Topographic Indices for Use Across Platforms (2006)

Topographic indices native to three devices were successfully simulated. Cross-platform comparisons may be limited for specific indices.
Contemplative WAC: Testing a Mindfulness-based Reflective Writing Assignment (2020)

This qualitative study examines the effects of the Mindfulness Journal Assignment (MJA), a semester-long integration implemented in five different university courses, to understand its potential for teaching and learning. Of particular interest were the patterns found in the reflective writing of students engaging in the MJA and the connection of those patterns to both classroom and Writing Across the Curriculum learning objectives. The most frequent themes occurring in the 111,906-word dataset were metacognitive awareness and self-regulation, both of which are significant for learning transfer and WAC. The findings of this study are promising in that the inclusion of a contemplative writing assignment is associated with positive habits of mind, such as metacognition and openness, which are prerequisites for common university course objectives such as critical thinking, problem-solving, and transfer. The development of these fundamental, domain-general skills makes this type of assignment an appropriate intervention for the emerging Contemplative Writing Across the Curriculum movement.
Hardware-assisted code obfuscation for FPGA soft microprocessors (2015)

Soft microprocessors are vital components of many embedded FPGA systems. As the application domain for FPGAs expands, the security of the software used by soft processors increases in importance. Although software confidentiality approaches (e.g. encryption) are effective, code obfuscation is known to be an effective enhancement that further deters code understanding for attackers. The availability of specialization in FPGAs provides a unique opportunity for code obfuscation on a per-application basis with minimal hardware overhead. In this paper we describe a new technique to obfuscate soft microprocessor code which is located outside the FPGA chip in an unprotected area. Our approach provides customizable, data-dependent control flow modification to make it difficult for attackers to easily understand program behavior. The application of the approach to three benchmarks illustrates a control flow cyclomatic complexity increase of about 7× with a modest logic overhead for the soft processor.
Changes in Arrangement of Lamella and Fine Crystallite in Fluorinated “Crystalline” Transparent Fibers with Drawing (2008)

Recently, we developed a “crystalline” plastic optical fiber with excellent heat resistance and dimensional stability. For the practical use of this crystalline optical fiber in the near future, an accurate control of the solid-state structure is indispensable because of the necessity of reducing light refraction at the crystalline/amorphous interface. In the present study, changes in the fine structure and lamella arrangement upon drawing poly[tetrafluoroethylene-co-(perfluoroethylvinylether)] (abbrev. EFA) transparent crystalline fibers were investigated by using wide-angle X-ray diffraction (WAXD) and small-angle X-ray scattering (SAXS) methods. The EFA was crystallized as a lamella crystal in the fibers and formed a thicker lamella (thickness: at least 27 nm). This polymer might form a “switchboard-type” lamella. Upon the drawing of the EFA fibers, four-point SAXS diagrams developed in the photograph, which implied that a particular type of layer structure, an alternately tilted lamella arrangement known as the herringbone, was formed. Moreover, the previously proposed packing mode of general fluorinated polymers was required to be modified from quasi-hexagonal to orthorhombic in a reciprocal lattice in order to assign all reflective indexes.
New Method for Synthesis of Aldehydes from Esters by Sodium Diisobutyl-<i>t</i>-butoxyaluminum Hydride (2007)

Abstract A new reducing agent, sodium diisobutyl-t-butoxyaluminum hydride (SDBBA), easily prepared by addition of sodium t-butoxide to DIBALH in THF at 0 °C or room temperature, readily reacts with representative esters to give the corresponding aldehydes in very good yields under mild conditions (0 °C).
Design and Synthesis of Biotin Analogues Reversibly Binding with Streptavidin (2015)

Two new biotin analogues, biotin carbonate 5 and biotin carbamate 6, have been synthesized. These molecules were designed to reversibly bind with streptavidin by replacing the hydrogen-bond donor NH group(s) of biotin's cyclic urea moiety with oxygen. Biotin carbonate 5 was synthesized from L-arabinose (7), which furnishes the desired stereochemistry at the 3,4-cis-dihydroxy groups, in 11% overall yield (over 10 steps). Synthesis of biotin carbamate 6 was accomplished from L-cysteine-derived chiral aldehyde 33 in 11% overall yield (over 7 steps). Surface plasmon resonance analysis of water-soluble biotin carbonate analogue 46 and biotin carbamate analogue 47 revealed that KD values of these compounds for binding to streptavidin were 6.7×10(-6) M and 1.7×10(-10) M, respectively. These values were remarkably greater than that of biotin (KD =10(-15) M), and thus indicate the importance of the nitrogen atoms for the strong binding between biotin and streptavidin.

Robust estimation of primaries by sparse inversion via one-norm minimization (2013)

ABSTRACT A recently proposed method called estimation of primaries by sparse inversion (EPSI) avoids the need for adaptive subtraction of approximate multiple predictions by directly inverting for the multiple-free subsurface impulse response as a collection of band-limited spikes. Although it can be shown that the correct primary impulse response is obtained through the sparsest possible solution, the original EPSI algorithm was not designed to take advantage of this result, and instead it relies on a multitude of inversion parameters, such as the level of sparsity per gradient update. We proposed and tested a new algorithm, named robust EPSI, in which we make obtaining the sparsest solution an explicit goal. Our approach remains a gradient-based approach like the original algorithm, but it is derived from a new biconvex optimization framework based on an extended basis-pursuit denoising formulation. Furthermore, because it is based on a general framework, robust EPSI can recover the impulse response in transform domains, such as sparsifying curvelet-based representations, without changing the underlying algorithm. We discovered that the sparsity-minimizing objective of our formulation enabled it to operate successfully on a variety of synthetic and field marine data sets without excessive tweaking of inversion parameters. We also found that recovering the solution in alternate sparsity domains can significantly improve the quality of the directly estimated primaries, especially for weaker late-arrival events. In addition, we found that robust EPSI produces a more artifact-free impulse response compared to the original algorithm.

A Role for the Aspartyl Protease from the Human Immunodeficiency Virus Type 1 (HIV‐1) in the Orchestration of Virus Assembly (1990)

Functional HIV-1 protease (PR) is required for the maturation of viral proteins, for the appearance of characteristic structural features in the virion (as determined by electron microscopy), and for the final assembly of mature virus. Most importantly, HIV-1 PR activity is required for the development of infectivity. Still largely undefined, however, is the timing and control of protease action in this assembly process. Based on the three-dimensional structure of HIV-1 PR2,3 and experimental data reported in the literature, we propose a comprehensive virus assembly model that highlights the role of HIV-1 PR, suggests further experiments to verify the validity of the model, and poses specific questions relevant to the ultimate exploitation of HIV-1 protease as a therapeutic target.
Proteomic Identification of Mitochondrial Targets of Arginase in Human Breast Cancer (2013)

We have previously reported arginase expression in human breast cancer cells and demonstrated that the inhibition of arginase by N(ω) hydroxy L-arginine (NOHA) in MDA-MB-468 cells induces apoptosis. However, arginase expression and its possible molecular targets in human breast tumor samples and potential clinical implications have not been fully elucidated. Here, we demonstrate arginase expression in human breast tumor samples, and several established breast cancer cell lines, in which NOHA treatment selectively inhibits cell proliferation. The over-expression of Bcl2 in MDA-MB-468 cells abolished NOHA-induced apoptosis, suggesting that the mitochondria may be the main site of NOHA's action. We, therefore, undertook a proteomics approach to identify key mitochondrial targets of arginase in MDA-MB-468 cells. We identified 54 non-mitochondrial and 13 mitochondrial proteins that were differentially expressed in control and NOHA treated groups. Mitochondrial serine hydroxymethyltransferase (mSHMT) was identified as one of the most promising targets of arginase. Both arginase II (Arg II) and mSHMT expressions were higher in human breast tumor tissues compared to the matched normal and there was a strong correlation between Arg II and mSHMT protein expression. MDA-MB-468 xenografts had significant upregulation of Arg II expression that preceded the induction of mSHMT expression. Small inhibitory RNA (siRNA)-mediated inhibition of Arg II in MDA-MB-468 and HCC-1806 cells led to significant inhibition of both the mSHMT gene and protein expression. As mSHMT is a key player in folate metabolism, our data provides a novel link between arginine and folate metabolism in human breast cancer, both of which are critical for tumor cell proliferation.
Declining bioavailability and inappropriate estimation of risk of persistent compounds (1997)

Abstract Earthworms ( Eisenia foetida) assimilated decreasing amounts of atrazine, phenanthrene, and naphthalene that had been incubated for increasing periods of time in sterile soil. The amount of atrazine and phenanthrene removed from soil by mild extractants also decreased with time. The declines in bioavailability of the three compounds to earthworms and of naphthalene to bacteria were not reflected by analysis involving vigorous methods of solvent extraction; similar results for bioavailability of phenanthrene and 4-nitrophenol to bacteria were obtained in a previous study conducted at this laboratory. We suggest that regulations based on vigorous extractions for the analyses of persistent organic pollutants in soil do not appropriately estimate exposure or risk to susceptible populations.
Purification and Characterization of the Coliphage N4-coded Single-stranded DNA Binding Protein (1989)

We have purified and characterized a single-stranded DNA binding protein (N4 SSB) induced after coliphage N4 infection. It has a monomeric molecular weight of 31,000 and contains 10 tyrosine and 1-2 tryptophan amino acid residues. Its fluorescence spectrum is dominated by the tyrosine residues, and their fluorescence is quenched when the protein binds single-stranded DNA. Fluorescence quenching was used as an assay to quantitate binding of the protein to single-stranded nucleotides. The N4 single-stranded DNA binding protein binds cooperatively to single-stranded nucleic acids and binds single-stranded DNA more tightly than RNA. The binding involves displacement of cations from the DNA and anions from the protein. The apparent binding affinity is very salt-dependent, decreasing as much as 1,000-fold for a 10-fold increase in NaCl concentration. The degree of cooperativity (omega) is relatively independent of salt concentration. At 37 degrees C in 0.22 M NaCl, the protein has an intrinsic binding constant for M13 viral DNA of 3.8 x 10(4) M-1, a cooperativity factor omega of 300, and binding site size of 11 nucleotides per monomer. The protein lowers the melting point of poly(dA.dT).poly(dA-dT) by greater than 60 degrees C but cannot lower the melting transition or assist in the renaturation of natural DNA. N4 single-stranded DNA binding protein enhances the rate of DNA synthesis catalyzed by the N4 DNA polymerase by increasing the processivity of the N4 DNA polymerase and melting out hairpin structures that block polymerization.
Photorealistic rendering for augmented reality (2003)

This paper explores an image-based approach to improve photorealism for rendering synthetic objects in augmented reality. It uses pre-filtered high-dynamic range environment maps of the real scene, containing real lighting information, to render diffuse and glossy virtual objects with a multi-pass technique via texture mapping operation. In addition, the light sources, required for soft shadows generation, can be estimated from the maps. Soft shadows are added to the virtual objects using shadow buffer technique, which can utilize graphics hardware. This work can be beneficial for ARToolkit development in improving photorealism of virtual objects.
