Dynamic Alternative Routing - Modelling and Behaviour (1988)

DAR, dynamic alternative routing, is a simple but effective form of dynamic routing which is decentralised and which uses only a small amount of local information. This paper examines the modelling and behaviourial aspects of such a scheme. In particular various bounds are presented which hold for any kind of dynamic routing scheme, and can be used to assess the performance of DAR. DAR can be investigated by a simple analytical model, of familar fixed-point form, and simulation studies have verified its accuracy. A simple form of dimensioning is mentioned, and methods of setting trunk reservation parameters are discussed. These are necessary both to improve performance and prevent instability. Lastly, simple ways of extending DAR are examined.
Standardized container virtualization approach for collecting host intrusion detection data (2019)

Anomaly-based Intrusion Detection Systems (IDS) can be instrumental in detecting attacks on IT systems. For evaluation and training of IDS, data sets containing samples of common security-scenarios are essential. Existing data sets are not sufficient for training modern IDS. This work introduces a new methodology for recording data that is useful in the context of intrusion detection. The approach presented is comprised of a system architecture as well as a novel framework for simulating security-related scenarios.
A parallel computer architecture for real-time control applications in grasping and manipulation (2002)

A scheduling algorithm is presented for multiprocessor architectures based on either complete or incomplete crossbar interconnection networks. The proposed algorithm takes into account the communication delays between processors and minimizes both the execution time and the communication cost. The algorithms are verified by experiments on an INMOS T800 transputer-based system. The system consists of eight nodes connected by bidirectional serial communication lines forming a 3-dimensional hypercube.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Oxidative coupling of methane and oxidative dehydrogenation of ethane over strontium-promoted rare earth oxide catalysts (1998)

Sr-promoted rare earth (viz. La, Ce, Pr, Nd, Sm, Eu, Gd, Dy, Er and Yb) oxide catalysts (Sr/rare earth ratio = 0.1) are compared for their 

performance in the oxidative coupling of methane (OCM) to C 2 hydrocarbons and oxidative dehydrogenation of ethane (ODE) to ethylene at different 

temperatures (700 and 800°C) and CH 4 (or C 2 H 6 )/O 2 ratios (4-8), at low contact time (space velocity = 

102000 cm 3 g -1 h -1 ). For the OCM process, the Sr-La 2 O 3 catalyst shows the best performance. The 

Sr-promoted Nd 2 O 3 , Sm 2 O 3 , Eu 2 O 3 and Er 2 O 3 catalysts also show good 

methane conversion and selectivity for C 2 hydrocarbons but the Sr-CeO 2 and Sr-Dy 2 O 3 catalysts show very poor 

performance. However, for the ODE process, the best performance is shown by the Sr-Nd 2 O 3 catalyst. The other catalysts also show good 

ethane conversion and selectivity for ethylene; their performance is comparable at higher temperatures (≥800°C), but at lower temperature 

(700°C) the Sr-CeO 2 and Sr-Pr 6 O 11 catalysts show poor selectivity.
The Design and Implementation of A Search Engine Marketing Management System (SEMMS) Based on Service-Oriented Architecture Platform (2007)

Service-oriented architecture (SOA) can provide prompt and cost-effective service discoveries and responses to dynamic changing market conditions. In one of the three dimensions of SOA, reach and range, the search engine has played a very significant role toward the success of this business objective. Over the last few years, search engine marketing has become one of the fastest growing industries. Currently, search engine marketing is divided into two categories: paid and non-paid. Paid marketing includes Pay-per-Click (PPC), Contextual Targeted Text Ads, and Paid Inclusion. Non-paid marketing includes Organic Search Engine Optimization and Link Popularity. As this is still a relatively new market, most companies lack the knowledge or the tools to manage their marketing strategies and maximize the return of their investments (ROI). The purpose of this paper is to investigate the impact of this important dimension of SOA, reach and range, and to design a web-based Search Engine Marketing Management System (SEMMS), which can be effectively applied to technical aspects in managing paid and non-paid search engine marketing required in this SOA dimension. The functionalities of the system include managing keywords and links to a website as well as producing analytical reports to track the performance of the marketing campaign.
Expression of Interleukin-6, c-<i>Fos</i>, and zif268 mRNAs in Rat Ischemic Cortex (1995)

The expression of interleukin-6 (IL-6) mRNA in the focal ischemic rat cortex was studied by means of Northern hybridization. IL-6 mRNA was induced after permanent occlusion of the middle cerebral artery, reached a significant level at 3 h, and peaked at 12 h, i.e., approximately 10-fold increase in the ischemic zone compared with the nonischemic cortex or sham-operated controls. The increased IL-6 mRNA was elevated for at least 24 h. Low levels of IL-6 mRNA were detected in sham-operated rats or in the contralateral nonischemic cortex. The expression of c-fos and zif268 mRNAs, two early response genes, was rapid (increased by 1 h postischemia) and transient (returned to basal levels by 24 and 12 h, respectively), clearly having different kinetic patterns from that of IL-6 mRNA. The early response kinetic pattern of c-fos and zif268 mRNAs in focal ischemia suggests their transcriptional regulatory roles in response to ischemic insult, while the delayed induction pattern of IL-6 mRNA suggests a role for this pleiotropic cytokine in the inflammatory response to the focal ischemic damage of the brain.
QoS integration in web services (2003)

With the growing popularity of Web services, a general QoS support for Web services will play an important role for the success of this emerging technology. Unfortunately, current Web service environments do not offer comprehensive QoS support. In this paper, we present an approach that does not only enable the QoS integration in Web services, but also the selection of appropriate services based on QoS requirements regarding server and network performance as well as the mapping of QoS requirements onto the underlying QoS aware network at runtime.
The effect of different treatment methods of multiwalled carbon nanotubes on thermal and flexural properties of their epoxy nanocomposites (2010)

Abstract Multiwalled carbon nanotubes (MWCNTs) were oxidized using four different acid‐treatment methods followed by their functionalization with 3‐aminopropyltriethoxysilane (3‐APTES). Diglycidyl ether of bisphenol A (DGEBA) nanocomposites with unmodified and silanized MWCNTs (0.2 wt %) were prepared by a cast molding method. The effect of functionalization of MWCNTs on thermal, flexural, and morphological properties of the epoxy nanocomposites were studied. The epoxy/MWCNTs nanocomposites were characterized by thermogravimetric analysis, flexural testing, and field emission electron microscopic analysis. The results showed that the silanization of MWCNTs which were oxidized by a two‐step process using nitric acid and hydrochloric acid showed better thermal and flexural properties due to good interfacial adhesion between MWCNTs and the epoxy matrix. © 2010 Wiley Periodicals, Inc.

A Comparison of Model-Based and Incremental Case-Based Approaches to Electronic Fault Diagnosis (1994)

CBR seems well suited to fault diagnosis because diagnostic episodes naturally form cases and much of expert competence seems to be based on reuse of old solutions. However, in many diagnosis problems it is difficult to compile a complete case description in advance, consequently the conventional one-shot case retrieval methodology will not work. In this paper we introduce a set of fault diagnosis problems that have this characteristic and we describe a model-based goal-driven system that produces focused questions that request extra information required for diagnosis. The central contribution in this paper is a description of a CBR system that also has this characteristic of producing focused questions in diagnosis. We describe the information theoretic mechanism that allows the CBR system to do this and we present an evaluation of the CBR system and a comparison of the two systems. Introduction The major attraction of CBR is its cognitive plausibility. It is clear that much of human...
An <i>in vivo</i> automated shimming method taking into account shim current constraints (1995)

Many in vivo imaging techniques require magnetic field homogeneity in the volume of interest. Shim coils of the second and third order spherical harmonics have been used successfully to compensate for complicated field variations caused by the human anatomy itself. The available currents of these coils are invariably limited. In this note we demonstrate that these limits significantly affect the optimal shim condition. We propose an automated in vivo shimming method for arbitrary volumes of interest using 3-dimensional (3D) field maps. This method is a modification of previous works using least-squares criteria. The main difference is that a constrained optimization is performed in vivo under the current limits of the shim coils, which improved the field homogeneity significantly over simple truncations of the least-squares solutions. This shimming method was used with head scans of five normal volunteers on a 4.0 tesla scanner. A fast double-echo sequence was used to obtain field maps, and a new field uniformity measure was derived for this method. The field mapping sequence was tested against a standard single-echo Dixon sequence used by previous investigators, and the stability of the shimming method was tested by repeated studies on the same subject.
A new capacitive type MEMS microphone (2010)

A new capacitive type of MEMS microphone is presented. In contrast to existing technologies which are highly specialized for this particular type of application, our approach is based on a standard process and layer system which has been in use for more than a decade now for the manufacturing of inertial sensors. For signal conversion, a mixed-signal ASIC with digital sampling of the microphone capacitance is used. The MEMS microphone yields high signal-to-noise performance (58 dB) after mounting it in a standard LGA-type package. It is well-suited for a wide range of potential applications and demonstrates the universal scope of the used process technology.
Highly Water‐Soluble, Fluorescent, Conjugated Fluorene‐Based Glycopolymers with Poly(ethylene glycol)‐Tethered Spacers for Sensitive Detection of <i>Escherichia coli</i> (2009)

Two bromide-bearing, fluorene-based, conjugated polymers with oligo(ethylene glycol)- and poly(ethylene glycol)-tethered spacers have been prepared by the Suzuki coupling polymerization of bromide-bearing, fluorene monomers. beta-Glucose and alpha-mannose residues have been covalently attached to the conjugated polymers by post-polymerization functionalization of the precursor polymers with thiol-functionalized carbohydrates under basic conditions through thioether linkage. A glucose-bearing glycopolymer with oligo(ethylene glycol)-tethered spacers (polymer A) displays poor water solubility. However, glycopolymers with poly(ethylene glycol)-tethered spacers (polymers B and C) are highly water-soluble due to their long, flexible, hydrophilic spacers. Incubation of the ORN178 strain of Escherichia coli (E. coli) with alpha-mannose-bearing glycopolymer (polymer C) results in the formation of fluorescent cell clusters, causing significant red shifts in UV/Vis absorption and fluorescent spectra of the polymer through multivalent cooperative interactions of the polymeric carbohydrates with the bacterial pili. In contrast, polymer C displays no interactions with a mutant ORN208 strain of E. coli.
Scannerless laser range camera (1999)

The requirement to quickly obtain 3D measurements is common to a variety of tasks in different fields of applications, i.e. robotics, space craft rendezvous and docking scenarios and industrial assemblies. In this paper, a novel type of non‐scanning optical 3D laser camera is presented. This is useful for both space and industrial applications. Avoiding any moving mechanical parts, the new sensor is able to exceed the frame rate and lateral resolution limits of common scanning devices, while providing both a grey‐scale image and a dense range image of the scene at the same time.
Preparation of conducting polysiloxane/polyaniline composites (2015)

ABSTRACT Polysiloxane/polyaniline microcomposites were prepared, in which polyaniline particles act as filler, thus combining the mechanical properties of polysiloxane matrix with conductivity of polyaniline. Two syntheses were evaluated: (1) homogeneous dispersion of a polyaniline colloid in the reaction mixture from which the polysiloxane matrix subsequently formed, and (2) the blending of previously prepared dry polyaniline particles with a liquid oligomeric siloxane resin followed by cure (“heterogeneous method”). Both methods lead to composites with evenly distributed filler. Electrical conductivity was achieved above 40 wt % of polyaniline, which is better obtained by the “heterogeneous” method. During the composite cure, the polyaniline particles, which are softer than the matrix, act as a catalyst and cause more efficient matrix crosslinking, thus leading to somewhat raised moduli. Although particulate fillers usually deteriorate the impact toughness, in the case of the prepared composites, the impact toughness was preserved due to the softer consistence of the filler, which hinders crack propagation. © 2015 Wiley Periodicals, Inc.

Direct Perception of Three-Dimensional Motion from Patterns of Visual Motion (1995)

Measurements of retinal motion along a set of predetermined orientations on the retina of a moving system give rise to global patterns. Because the form and location of these patterns depend purely on three-dimensional (3D) motion, the effects of 3D motion and scene structure on image motion can be globally separated. The patterns are founded on easily derivable image measurements that depend only on the sign of image motion and do not require information about optical flow. The computational theory presented here explains how the self-motion of a system can be estimated by locating these patterns.
Atrial Capture Detection with Endocardial Electrodes (1988)

A new method of evoked response detection, previously demonstrated in the ventricle, has been studied in the atrium at the time of routine pacemaker implant in 16 patients. The atrial evoked response was readily detectable in all patients due to excellent recovery from poststimulus polarization. In six patients, as experimental threshold-tracking pacemaker was used to automatically verify atrial capture and to generate strength-duration curves. It is concluded that this pacing technique is both simple and reliable, and that automatic atrial threshold tracking is feasible.
Increasing driving safety with a multiple vehicle detection and tracking system using ongoing vehicle shadow information (2010)

This paper proposes a vehicle detection and tracking system based on processing monochrome images captured by a single camera. The work has mainly been focused on detecting and tracking vehicles in daylight conditions, viewed from inside a vehicle. Unlike previous work, this approach uses vehicle shadow clues and vehicle edge information to obtain cost effective and fast estimation. The proposed method includes road area finding which has been implemented by a lane detection algorithm to avoid false detections of vehicles caused by the distraction of background objects. Assuming that lanes are successfully detected, vehicle presence inside the road area is hypothesized by using “shadow” as a cue. Hypothesized vehicle locations are verified using vertical edges. After extracting vehicles, the algorithm effectively tracks them using a Kalman filter based tracking algorithm. A vehicle has been instrumented with various sensors for the experiments. Several sequences from real traffic situations have been tested, obtaining highly accurate multiple vehicle detections. Tracking information is used to estimate time-to-collision (TTC) and warn the driver for a possible collision.
The Overtone Fiddle: An Actuated Acoustic Instrument (2011)

The Overtone Fiddle is a new violin-family instrument that incorporates electronic sensors, integrated DSP, and physical actuation of the acoustic body. An embedded tactile sound transducer creates extra vibrations in the body of the Overtone Fiddle, allowing performer control and sensation via both traditional violin techniques, as well as extended playing techniques that incorporate shared man/machine control of the resulting sound. A magnetic pickup system is mounted to the end of the fiddle's fingerboard in order to detect the signals from the vibrating strings, deliberately not capturing vibrations from the full body of the instrument. This focused sensing approach allows less restrained use of DSP-generated feedback signals, as there is very little direct leakage from the actuator embedded in the body of the instrument back to the pickup.
Individual Control and Quantification of 3D Spheroids in a High-Density Microfluidic Droplet Array (2020)

As three-dimensional cell culture formats gain in popularity, there emerges a need for tools that produce vast amounts of data on individual cells within the spheroids or organoids. Here, we present a microfluidic platform that provides access to such data by parallelizing the manipulation of individual spheroids within anchored droplets. Different conditions can be applied in a single device by triggering the merging of new droplets with the spheroid-containing drops. This allows cell-cell interactions to be initiated for building microtissues, studying stem cells' self-organization, or observing antagonistic interactions. It also allows the spheroids' physical or chemical environment to be modulated, as we show by applying a drug over a large range of concentrations in a single parallelized experiment. This convergence of microfluidics and image acquisition leads to a data-driven approach that allows the heterogeneity of 3D culture behavior to be addressed across the scales, bridging single-cell measurements with population measurements.
Homogeneous Perdehydrogenation and Perhydrogenation of Fused Bicyclic N-Heterocycles Catalyzed by Iridium Complexes Bearing a Functional Bipyridonate Ligand (2014)

Homogeneous perdehydrogenation of saturated bicyclic 2,6-dimethyldecahydro-1,5-naphthyridine and perhydrogenation of aromatic 2,6-dimethyl-1,5-naphthyridine with release and uptake of five molecules of H2 are efficiently achieved by iridium complexes bearing a functional bipyridonate ligand. Successive perhydrogenation and perdehydrogenation of 2,6-dimethyl-1,5-naphthryridine using a single iridium complex also proceed with the reversible interconversion of the catalytic species, depending on the presence or absence of H2.
Applying process simulation to software project scheduling (2004)

Good project scheduling is an essential yet extremely hard task in software management practice. The time needed to complete a development activity usually is known only roughly. Often, the completion of an activity is delayed due to unanticipated rework. In this paper, we show how process simulation can be utilized in order to support software managers in finding good schedules for their projects. We present a novel, discrete simulation model for software projects which explicitly takes a scheduling policy as input. The model represents task assignments, staff skill levels, component coupling, and rework caused by design changes. The simulation model is implemented in the ModL language of the general-purpose graphical simulation tool EXTEND [4]. As a first application of our project simulation model, we systematically study the performance of various so-called list policies for a sample project. The simulations quickly show what impact each list policy has on the expected progress and completion time of the sample project. We also provide a detailed analysis of the task assignments which actually occur in the simulations. The analysis clearly identifies the reasons why the list policies perform as observed.
Gas-Phase Separations of Protein and Peptide Ion Fragments Generated by Collision-Induced Dissociation in an Ion Trap (2002)

Ion mobility/time-of-flight mass spectrometry techniques have been used to examine distributions of fragment ions generated by collision-induced dissociation (CID) in a quadrupole ion trap. The mobility-based separation step prior to mass-to-charge (m/z) analysis reduces spectral congestion and provides information that complements m/z-based assignments of peaks. The approach is demonstrated by examining fragmentation patterns of insulin chain B (a 30-residue peptide), and ubiquitin (a protein containing 76 amino acids). Some fragments of ubiquitin show evidence for multiple stable conformations.
Synovial fluid antigen-presenting cells unmask peripheral blood T cell responses to bacterial antigens in inflammatory arthritis (1990)

We and others have previously shown that synovial fluid (SF) mononuclear cells (MC) from patients with both reactive arthritis and other inflammatory arthritides proliferate in vitro in response to bacteria clinically associated with the triggering of reactive arthritis. In all cases, such SFMC responses are greater than the corresponding peripheral blood (PB) MC responses, often markedly so, and the mechanism for this is unclear. We have investigated this phenomenon by comparing the relative abilities of irradiated non-T cells derived from PB and SF to support autologous T cell responses to ReA-associated bacteria. Seven patients whose SFMC had been shown previously to respond to bacteria were studied. We demonstrate antigen-specific responses of PB T cells to bacteria in the presence of SF non-T cells which are in marked contrast to the minimal responses of either unfractionated PBMC or PB T cells reconstituted with PB non-T cells. We also show that PB, but not SF T cells respond strongly to autologous SF non-T cells in the absence of antigen or mitogen. These findings demonstrate that SF antigen-presenting cells (APC) are potent activators of PB T cells. We conclude that the contrasting responses of SFMC and PBMC to bacterial antigens may be accounted for at least in part by an enhanced ability of SF APC to support T cell proliferative responses.
THE PREPARATION AND CALCINATION OF AMMONIUM URANATES: A LITERATURE SURVEY. (1968)

The preparation and calcination of ammonium uranates is reviewed. Topics covered include the preparation of ammonium uranates by precipitation or soild state reaction; the effects of preparation conditions upon the composition, structure, morphology, surface area, and filtration of ammonium uranates; the thermal decomposition and reduction of ammonium uranates; and the effect of calcination conditions on the physical properties of the resultant powder.
