Parametric model fitting: from inlier characterization to outlier detection (1998)

Presents a framework for the fitting of multiple parametric models. It comprises of a module for parameter estimation based on a solution for generalized least squares problems and of a procedure for error propagation, which takes both the geometric arrangement of the input data points and their precision into account. The results from error propagation are used to complement each model parameter with a precision estimate, to assign an inlier set of data points supporting the fit to each extracted model, and to determine the a priori unknown total number of meaningful models in the data. Although the models are extracted sequentially, the final result is almost independent of the extraction order. This is achieved by further statistical processing which controls the mutual exchange of inlier data between the models. Consequently, sound data classification as well as robust fitting are guaranteed even in areas where different models intersect or touch each other. Apart from the input data and its precision, the framework relies on only one additional control parameter: the confidence level on which the various statistical tests for data and model classification are carried out. We demonstrate the algorithmic performance by fitting straight lines in 2D and planes in 3D with applications to problems of computer vision and pattern recognition. Synthetic data is used to show the robustness and accuracy of the scheme. Image data and range data are used to illustrate its applicability and relevance in respect of real-world problems, e.g., in the domain of image feature extraction.

Kunitz-Type Proteinase Inhibitors Derived by Limited Proteolysis of the Inter-α-Trypsin Inhibitor, IV. The Amino Acid Sequence of the Human Urinary Trypsin Inhibitor Isolated by Affinity Chromatography (1981)

An acid-resistant trypsin inhibitor from human urine and serum is released in vivo by limited proteolysis from the high molecular acid-labile inter-alpha-trypsin inhibitor. The inhibitor shows an apparent molecular mass of 30 000 Da and is composed of two Kunitz-type domains. The domains are released in vitro by prolonged tryptic hydrolysis. The C-terminal domain is responsible for antitryptic activity. For the other domain no inhibitory activity towards proteinases, i.e. chymotrypsin, trypsin, pancreatic and leucocytic elastase has been demonstrated so far. The polypeptide chain comprising both domains consists of 122 residues and has a molecular mass of only 13 400 Da. In this work we have found that both, the N-terminal extension peptide with 21 residues and the "inactive" domain are linked O-glycosidically and N-glycosidically, respectively, with large carbohydrate moieties. The N-terminal amino acid sequence of the human urinary trypsin inhibitor was determined by solid-phase Edman degradation of a single peptide. The molecular mass calculated for the total polypeptide chain of 143 residues should be 15 340 Da; from the difference to the measured value (30 000 Da) it is concluded that the glycopeptide contains a considerable carbohydrate moiety.
Mesalamine Foam Enema<i>Versus</i>Mesalamine Liquid Enema in Active Left-Sided Ulcerative Colitis (2008)

A 4-wk treatment of 1 g mesalamine foam induced a clinical remission in 68% patients versus 73% with 1 g mesalamine liquid enema. Although the noninferiority of mesalamine foam could not be strictly demonstrated at W4 in the PP analysis, it was achieved in the ITT population and at W2 in both populations. Mesalamine foam represents a therapeutic alternative to mesalamine liquid enema in patients with mild-to-moderate active proctitis and proctosigmoiditis.
Multi-Level DC-DC Converter for High Gain Applications (2013)

The output voltage from most renewable energy sources like photovoltaic arrays and fuel cells will be at low level. This must be stepped up considerably for practical utilization or grid connection. The presented multilevel boost converter DC-DC converter topology consists of the conventional boost converter and voltage doubler stages to provide high voltage gain. The proposed topology uses only one switch along with one inductor, (2N-1) diodes and (2N-1) capacitors for obtaining an output which is N times the conventional boost converter. In this topology, each device blocks only one voltage level. The main advantages of this topology are continuous input current, large gain without high duty cycle or transformer, modularity and use of devices with low voltage ratings. Experimental results obtained from the 100W prototype demonstrate the voltage gain capability of the converter and validates the converter design. DOI: http://dx.doi.org/10.11591/ijpeds.v4I1.4870
Microchemical Investigations of Dust Emitted by a Lead Smelter (1999)

Dusts emitted by an important pyrometallurgical lead smelter have been sampled within the pipes of the grilling and furnace working units before and after the filtering systems, respectively. Particle size distribution, elementary analyses, and X-ray powder diffraction analysis indicate PbS, PbSO4, PbSO4·PbO, Pb, ZnS small particles less than 5 μm in size to contribute mainly to the current atmospheric pollution. Although at least 90% of dust are retained on the filters, the amounts of the respirable smaller particles are significantly larger in the current emission. The average chemical speciation was found to be analogous for the dust samples collected before and after the filters. The scanning electron microscopy associated with energy-dispersive X-ray analysis and Raman microspectrometry established the morphology and chemical composition at the level of individual particles. A lot of minor compounds (α-PbO, β-PbO, FeS2, FeO, Fe3O4, α-Fe2O3, FeCO3, CaSO4·2H2O, CaCO3, CdS, ...) were found as small heterogeneous individual particles (less than 5 μm) in the heterogeneous particles of grilling dust. Among the homogeneous particles of furnace dust, amorphous C, β-PbO, PbO·PbCl2, FeO, CdS, CdSO4 were often detected as homogeneous mixtures with the major compounds within the particles.
Technology Review - A Survey of Recent Patents of Fin-and-Tube Heat Exchangers (2000)

This study presents updated information about patents of the fin-and-tube heat exchangers during 1981 ∼ 1999. A total of 51 patents were examined and compared. Fin patterns like convex-louver, enhanced wavy, enhanced slit, enhanced louver, vortex generators, and several special fin patterns are reported in the present report. It is recommended that further detailed examinations via numerical simulation or experimental investigation be carried out in the future to gain further insight of these fin designs.
The Complete Pivoting Conjecture for Gaussian Elimination is False (1992)

A famous conjecture concerning Gaussian Elimination was recently "settled" as false, by a counterexample found on a Cray supercomputer.Mathematica did not yield the same conclusion when given identical data, reminding us of the care needed when proving mathematical statements using rounded arithmetic.Indeed, the conjecture is false, but a proper counterexample requires modifications of the data.In this note, we provide proper counterexamples by modifying numbers computed in rounded arithmetic by Nick Gould on a Cray.
Short-Term Load Forecasting, Profile Identification, and Customer Segmentation: A Methodology Based on Periodic Time Series (2005)

Results from a project in cooperation with the Belgian National Grid Operator ELIA are presented in this paper. Starting from a set of 245 time series, each one corresponding to four years of measurements from a HV-LV substation, individual modeling using Periodic Time Series yields satisfactory results for short-term forecasting or simulation purposes. In addition, we use the stationarity properties of the estimated models to identify typical daily customer profiles. As each one of the 245 substations can be represented by its unique daily profile, it is possible to cluster the 245 profiles in order to obtain a segmentation of the original sample in different classes of customer profiles. This methodology provides a unified framework for the forecasting and clustering problems.
Estimation (2001)

In this chapter, you expand on the knowledge of estimation gained in Chapter 1 to make point and interval estimates of the effects you detected in Chapter 3.
Feature Selection in Source Camera Identification (2006)

Source camera identification is the process of discerning which camera has been used to capture a particular image. In our previous work, we tackled the problem with a vector of thirty-six features to train and test the classifier. The features include the lens aberration parameters and statistical measurements from pixel intensities. In this paper, we focus on reducing the feature set by stepwise discriminant analysis. Simulation is carried out to evaluate the classifier's performance by using the full feature set, reduced feature sets and randomly selected feature sets. The results show that the reduced feature sets can decrease the processing time while also maintain or even improve the classification accuracy under some circumstances.
A computer-based multipoint vibration system for process plant rotating equipment (1988)

The authors describe the installation of a computer-based multipoint bearing vibration monitoring system in an oil refinery's process plant. The multipoint system, installed on centrifugal pumps, fans, and compressors in the 40 to 450 hp range, was developed in response to several serious plant fires which originated at centrifugal pump sea/bearing failures. It is concluded that detection of incipient mechanical failures has met the original objectives to reduce fire risk, production losses, and machinery downtime. Despite the limitations of the single probe on most items of equipment and the relatively course alarm setting, the system predicts maintenance problems and thereby reduces costs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Some Physical Properties of Nickel-Iron Alloys (1920)

The specific heats, thermal conductivities, thermoelectric powers, and specific resistances have been determined for a series of iron-nickel alloys of exceptional purity and definitely known composition.The specific heat (25\ifmmode^\circ\else\textdegree\fi{} to 100\ifmmode^\circ\else\textdegree\fi{} C.) varies only slightly with change in composition, but gives, nevertheless, a well defined maximum at 35 per cent. nickel. The thermal conductivity (20\ifmmode^\circ\else\textdegree\fi{} to 100\ifmmode^\circ\else\textdegree\fi{} C.) on the other hand, shows a much larger variation. with a value for 35 per cent. nickel of only one fifth of that for either pure iron or pure nickel. The thermoelectric power (o\ifmmode^\circ\else\textdegree\fi{} to 96\ifmmode^\circ\else\textdegree\fi{} C.) against copper exhibits a marked minimum at 35 per cent. nickel with maxima at about 20 per cent. and 50 per cent. The specific resistance at o\ifmmode^\circ\else\textdegree\fi{} C. shows a marked maximum at 35 per cent. nickel, more than five times the value for either pure iron or pure nickel. The relative increase is not so great as the temperature is raised to 700\ifmmode^\circ\else\textdegree\fi{} C. The temperature coefficient of resistance, considering the whole range (o\ifmmode^\circ\else\textdegree\fi{} to 700\ifmmode^\circ\else\textdegree\fi{} C.). is a minimum for the 35 per cent. nickel.These facts are in general agreement with the anomalies in other properties shown by nickel-iron or nickel-steel of this composition and point to the formation of the definite compound ${\mathrm{Fe}}_{2}$Ni.
Collaborative Debugging (2013)

Debugging - the process of finding and correcting programming mistakes - faces too the challenges of distributed and collaborative development. The debugging tools commonly used by programmers are integrated into traditional development environments such as Eclipse or Visual Studio, and hence do not offer specific features for collaboration or remote shared usage. In this paper, we describe CDB, a debugging technique and integrated tool specifically designed to support effective collaboration among developers during shared debugging sessions. We also discuss the design and results of an empirical study aimed at identifying features that can ameliorate the effectiveness of collaborative debugging processes, and at evaluating the usefulness of our CDB collaborative debugging approach. The study suggests that CDB's collaboration features are often perceived as important for effective debugging, and can improve the overall debugging experience in collaborative settings.
A pantograph linkage parallel platform master hand controller for force-reflection (2003)

The authors discuss the kinematics of a serial/parallel six degree-of-freedom generalized hand controller for teleoperation. A description of the device is presented with equations needed for control of a remote manipulator. The pantograph linkages extend the workspace of traditional platform designs, while the parallel structure provides force regulation at the platform that is well suited for force-feedback to a teleoperator. The generalized teleoperator controller described will be part of a larger telerobotics system comprising a radio-controlled robotic arm module with appropriate end-effectors and a general-purpose supervisory controlled system. The robotic system is planned for remote handling of toxic solid and liquid debris.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Quantitative Security Risk Assessment of Android Permissions and Applications (2013)

The booming of the Android platform in recent years has attracted the attention of malware developers. However, the permissions-based model used in Android system to prevent the spread of malware, has shown to be ineffective. In this paper, we propose DroidRisk, a framework for quantitative security risk assessment of both Android permissions and applications (apps) based on permission request patterns from benign apps and malware, which aims to improve the efficiency of Android permission system. Two data sets with 27,274 benign apps from Google Play and 1,260 Android malware samples were used to evaluate the effectiveness of DroidRisk. The results demonstrate that DroidRisk can generate more reliable risk signal for warning the potential malicious activities compared with existing methods. We show that DroidRisk can also be used to alleviate the overprivilege problem and improve the user attention to the risks of Android permissions and apps.
Chandi: 160-KJ Capacitor Bank for Plasma Applications (2005)

Summary form only given. The design procedure, fabrication details and experimental results of a high-energy capacitor bank is reported in this paper. The bank consists of 8 capacitors connected in parallel, each having a capacitance of 178 muF giving a total of 1424 muF. The bank is charged at 15 kV using a 28 kV power supply which charges the capacitors in 65 seconds utilizing full wave-charging technique. The total energy of the bank is 160 kJ at 15 kV. A modeling of power supply was done so that all the components involved are utilized to their operating limits safely. Moreover, to give fault protection to the capacitor bank we have implemented neutral control technique in the power supply. The capacitor bank is discharged to the inductive load through an ignitron switch of very high Coulomb rating and capable of withstanding high voltages at its electrodes. We have also successfully tested our fiber optic isolated voltage diagnostic system on this high-energy capacitor bank. The cables used for connecting capacitor bank with ignitron switch are used in parallel to give them collective capability of bearing bank discharge currents. These cables are capable of holding high DC voltages (40 kV), which appear at the time of charging of the bank. To check the current delivering capability of bank, it is discharged through a small inductive load made of thick copper wire. The bank is fabricated for various plasma applications requiring production of high magnetic fields
Validating the unit correctness of spreadsheet programs (2004)

Financial companies, engineering firms and even scientists create increasingly larger spreadsheets and spreadsheet programs. The creators of large spreadsheets make errors and must track them down. One common class of errors concerns unit errors, because spreadsheets often employ formulas with physical or monetary units. In this paper, we describe XeLda, our tool for unit checking Excel spreadsheets. The tool highlights cells if their formulas process values with incorrect units and if derived units clash with unit annotations. In addition, it draws arrows to the sources of the formulas for debugging. The tool is sensitive to many of the intricacies of Excel spreadsheets including tables, matrices, and even circular references. Using XeLda, we have detected errors in some published scientific spreadsheets.
THE BONDING OF PROSTHESES TO BONE BY CEMENT (1964)

1. The use of acrylic cement in bonding femoral head prostheses to bone is described. 2. No sign of deterioration of the bond between the cement and bone has been seen in histological preparations up to three and a quarter years after operation, and no harmful effects have been recognised, or suspected, in 455 patients in whom it has been used. 3. The technique is considered justifiable in elderly patients where the medullary canal is large and the cortex of the femur is thin and brittle.
Widely tunable erbium-doped fiber ring laser over 80 nm (1999)

We propose and demonstrate a widely wavelength tunable EDF ring laser utilizing a long EDF. The wavelength tunable range over 80 nm (1520 nm-1600 nm) has been achieved by using an intracavity fiber Fabry-Perot filter.
Relation between power spectrum time course during ventricular fibrillation and electromechanical dissociation. Effects of coronary perfusion and nifedipine (1986)

To relate the evolution of ventricular fibrillation (VF) to the haemodynamic recovery after cardioversion, we characterized the differences in the ECG power spectrum (PS) time course, among different types of VF: under control conditions, with previous administration of nifedipine and on cardiopulmonary bypass (CPB). In the first few seconds VF showed a PS with a narrow peak between 8 and 15 Hz and its higher harmonics, suggesting some organization and regularity. In the following 40 seconds, the arrhythmia accelerated slightly, maintaining an organized spectrum. Afterwards, the PS became slow and irregular, losing its initial characteristics after 60 seconds. Conversely, VF on CPB maintained its organized PS, over a prolonged period. Previous administration of 0.32, 0.64 mg kg-1 of nifedipine maintained the initial characteristics of the PS for 90 and 150 seconds. Similar results were obtained with previous autonomic blockade. In another group of dogs, defibrillation was performed after successive periods of VF, to study electromechanical dissociation (EMD). In all control dogs, EMD was observed after 90 seconds of VF. Pretreatment with nifedipine postponed EMD until 120-150 seconds and was not observed in dogs on CPB. The PS time course during VF seems a reliable method of analyzing and quantifying the different types of VF. It could be related with the onset of EMD, reflecting the metabolic alterations that happen during VF. Nifedipine could delay the ischaemic effects during VF and increase the possibility of successful cardiac resuscitation.
