Virtual-CPU Scheduling in the Quest Operating System (2011)

This paper describes the scheduling framework for a new operating system called "Quest". The three main goals of Quest are to ensure safety, predictability and efficiency of software execution. For this paper, we focus on one aspect of predictability, involving the integrated management of tasks and I/O events such as interrupts. Quest's scheduling infrastructure is based around the concept of a virtual CPU (VCPU). Using both Main and I/O VCPUs, we are able to separate the CPU bandwidth consumed by tasks from that used to complete I/O processing. We introduce a priority-inheritance bandwidth-preserving server policy for I/O management, called PIBS. We show how PIBS operates with lower cost and higher throughput than a comparable Sporadic Server for managing I/O transfers that require small bursts of CPU time. Using a hybrid system of Sporadic Servers for Main VCPUs, and PIBS for I/O VCPUs, we show how to maintain temporal isolation between multiple tasks and I/O transfers from different devices. We believe Quest's VCPU scheduling infrastructure is scalable enough to operate on systems supporting large numbers of threads. For a system of 24 Main VCPUs, we observe a CPU scheduling overhead of approximately 0.3% when VCPU budget is managed in 1ms units.
A Convenient Route to <i>N</i>-[2-(Fmoc)aminoethyl]glycine Esters and PNA Oligomerization Using a Bis-<i>N</i>-Boc Nucleobase Protecting Group Strategy (2008)

A simple and practical synthesis of the benzyl, allyl, and 4-nitrobenzyl esters of N-[2-(Fmoc)aminoethyl]glycine is described starting from the known N-(2-aminoethyl)glycine. These esters are stored as stable hydrochloride salts and were used in the synthesis of peptide nucleic acid monomers possessing bis-N-Boc-protected nucleobase moieties on the exocyclic amino groups of ethyl cytosin-1-ylacetate, ethyl adenin-9-ylacetate and ethyl (O(6)-benzylguanin-9-yl)acetate. Upon ester hydrolysis, the corresponding nucleobase acetic acids were coupled to N-[2-(Fmoc)aminoethyl]glycine benzyl ester or to N-[2-(Fmoc)aminoethyl]glycine allyl ester in order to retain the O(6) benzyl ether protecting group of guanine. The Fmoc/bis-N-Boc-protected monomers were successfully used in the Fmoc-mediated solid-phase peptide synthesis of mixed sequence 10-mer PNA oligomers and are shown to be a viable alternative to the currently most widely used Fmoc/Bhoc-protected peptide nucleic acid monomers.
An Adaptive Channel Estimation Method Based on Doppler Shift Estimation in mobile WIMAX (2007)

An adaptive channel estimation method in 802. 16 e system, based on Doppler shift estimation, is proposed. The coherence time can be gotten through Doppler shift estimation. Then the time domain channel impulse response (CIR) gotten by least squares (LS) algorithm can be refined according to the correlation duration the coherence time. The simulation results in the frequency band of 2.4 GHz show that the proposed method achieves a good bit error rate (BER) performance according to the speed variance of the vehicles.
Single snapshot imaging of optical properties (2013)

A novel acquisition and processing method that enables single snapshot wide field imaging of optical properties in the Spatial Frequency Domain (SFD) is described. This method makes use of a Fourier transform performed on a single image and processing in the frequency space to extract two spatial frequency images at once. The performance of the method is compared to the standard six image SFD acquisition method, assessed on tissue mimicking phantoms and in vivo. Overall both methods perform similarly in extracting optical properties.
The movement disorder of reflex sympathetic dystrophy (1990)

We present 43 patients with reflex sympathetic dystrophy (RSD) who manifested abnormalities of movement. The patients have focal dystonia, weakness, spasms, tremor, difficulty initiating movement, and increased tone and reflexes. These motor signs and symptoms may precede other manifestations of the illness by weeks or months. They most frequently, but not invariably, occur concomitantly with sudomotor or vasomotor changes and pain. Lioresal is effective in reducing spasms. Early in the course of RSD, the motor manifestation may be alleviated by intense sympathetic blockade or sympathectomy. In many patients, the movement disorder becomes independent of sympathetic innervation.
Natural photonic engineers (2002)

The structural colors of animals have provided an attractive means of advertisement for those reflectors designed and manufactured by humans. Over the past 30 years, optics well-known to the physicist have been emerging, example after example, in nature. But suddenly animals are becoming the first stage in the optical design process. Biologists and physicists have begun serious optics-based projects where results will be supplied by evolution. But it is the recent finding of photonic crystals in animals that has really triggered a surge in interest. Animals, it would seem, have plenty to teach us, not only in terms of the design of their optical structures, but also in their engineering. At a recent car show in Sydney, the demonstration of a new four-wheel-drive revealed a novel type of paint as well. The vehicle appeared blue from the front…but changed entirely to green when viewed from behind! The manufacturers had replaced pigments with ‘structural colors’. The secret behind this coating lies in its self-positioning reflector. Small fragments of thin-films, which cause colored reflections, are mixed within a matrix of transparent paint. When the paint is applied, the thin-films float to the surface so that all are orientated similarly, parallel with the car body, and reflect the same wavelength of light in each direction. As the direction of observation changes, different wavelengths are observed. These thin-film particles are, essentially, butterfly scale analogues.

A resistolog survey of the Loma Alto-Seven Sisters area of McMullen and Duval counties, Texas (1946)

Abstract Additional Resistolog field data are shown. This survey is in the Loma Alto-Seven Sisters area of McMullen and Duval Counties, Texas. The subsurface geology of this area is also shown along with an electric log cross section to which Resistologs have been added. Four of the apparent resistivity curves employed for calculating Resistologs are included for demonstrating the relatively great extent to which apparent resistivity may be influenced by shallow inhomogeneities along a traverse of electrodes which are moved for securing a variation in electrode separation. Several cases of direct detection of oil and gas saturation and successful structural correlations are presented.
Assessment of Acute Radiation-Induced Pulmonary Changes Using Computed Tomography (1986)

In a prospective study of acute radiation-induced pulmonary changes, CT scans of 54 patients were performed before and at preselected times during the 6 months following fractionated radiation therapy of the thorax. The CT films were evaluated independently by three diagnostic radiologists and 36 patients were scored as having postirradiation pulmonary findings. The average interobserver agreement for this scoring was approximately 85%. The end point was observed as an increase in lung density within the irradiated volume on a follow-up CT examination. All 36 patients demonstrated lung opacities in an irregular, homogeneous, or nonhomogeneous pattern within the radiation beam boundaries. In addition, the following characteristics were observed at various frequencies in these 36 patients: extension of the changes across anatomic tissue boundaries (50%), air bronchograms (25%), loss of lung volume (15%), and pleural thickening (15%). Confinement of the findings within the irradiated volume was the only specific characteristic of postirradiation changes. In two patients the changes appeared as sharply defined, nodular opacities and were considered to be atypical of radiation damage. These were subsequently confirmed to be metastases. Prospective assessment of an adequate number of patients has helped to establish the CT appearance of acute radiation-induced pulmonary effects and, hence, to minimize its confusion with malignancies and other abnormalities.
Multi-objective design optimization of the complete valve system in an adjustable linear hydraulic damper (2010)

Adjustable linear hydraulic dampers are widely used in high-speed trains to improve their ride comfort and stability, the distinctive damping characteristics of the dampers are intrinsically predetermined by their inner complete valve systems. Therefore, design of the complete valve system parameters for each damper type is of crucial importance. A multi-objective design optimization model for the concept of optimizing both the technical and economic capabilities of a three-valve complete valve system in a hydraulic damper was formulated, based on full damper dynamics modelling. A linear weighted criterion method was used to transform the established multi-objective problem to a single-objective problem, and a computer package employing the genetic algorithm for the optimization search was developed. Implementation of the design optimization was performed, and an optimal result, with about 10.29 per cent improvement of the overall fitness value, was obtained. Simulation results show that the optimal result satisfies all the competing objectives well within the constraints, except for some minor and tolerable tradeoffs in the relief valve response performance. Prototype experiments validated that the prototype dampers have obtained excellent damping characteristics, as expected. Thus, the complete valve system of the hydraulic damper was comprehensively optimized, with respect to both the technical and economic concerns. The approach developed in this work has already been applied to the engineering design of several hydraulic damper products in industry.
Wafer-to-Wafer Alignment for Three-Dimensional Integration: A Review (2011)

This paper presents a review of the wafer-to-wafer alignment used for 3-D integration. This technology is an important manufacturing technique for advanced microelectronics and microelectromechanical systems, including 3-D integrated circuits, advanced wafer-level packaging, and microfluidics. Commercially available alignment tools provide prebonding wafer-to-wafer misalignment tolerances on the order of 0.25 μm. However, better alignment accuracy is required for increasing demands for higher density of through-strata vias and bonded interstrata vias, whereas issues with wafer-level alignment uniformity and reliability still remain. Three-dimensional processes also affect the alignment accuracy, although the misalignment could be reduced to certain extent by process control. This paper provides a comprehensive review of current research activities over wafer-to-wafer alignment, including alignment methods, accuracy requirements, and possible misalignments and fundamental issues. Current misalignment concerns of the major bonding approaches are discussed with detailed alignment results. The fundamental issues associated with wafer alignment are addressed, such as alignment mechanisms, uniformity, reproducibility, thermal mismatch, and materials. Alternative alignment approaches are discussed, and perspectives for wafer-to-wafer alignment are given.
A Comparison on Histogram Based Image Matching Methods (2006)

Using colour histogram as a stable representation over change in view has been widely used for object recognition. In this paper, three newly proposed histogram-based methods are compared with other three popular methods, including conventional histogram intersection (HI) method, Wong and Cheung's merged palette histogram matching (MPHM) method, and Gevers' colour ratio gradient (CRG) method. These methods are tested on vehicle number plate images for number plate classification. Experimental results disclose that, the CRG method is the best choice in terms of speed, and the GWHI method can give the best classification results. Overall, the CECH method produces the best performance when both speed and classification performance are concerned.
Modeling organizations for information systems requirements engineering (2002)

In attempting to understand information system environments during requirements engineering, it is often helpful to have an understanding of the 'whys' as well as the 'whats' about the environment. A natural way to answer why questions is by tracing them to goals. In an organizational environment, however, the whys do not originate from a single set of given goals. Organizational agents depend on each other for goals to be achieved, tasks to be performed, and resources to be furnished. A requirements model that captures knowledge about an organizational environment can be enriched by including the network of dependency relationships among agents. A set of intentional operators for modeling dependencies among agents is proposed, and a preliminary axiomatic characterization is presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Supervised hashing with latent factor models (2014)

Due to its low storage cost and fast query speed, hashing has been widely adopted for approximate nearest neighbor search in large-scale datasets. Traditional hashing methods try to learn the hash codes in an unsupervised way where the metric (Euclidean) structure of the training data is preserved. Very recently, supervised hashing methods, which try to preserve the semantic structure constructed from the semantic labels of the training points, have exhibited higher accuracy than unsupervised methods. In this paper, we propose a novel supervised hashing method, called latent factor hashing(LFH), to learn similarity-preserving binary codes based on latent factor models. An algorithm with convergence guarantee is proposed to learn the parameters of LFH. Furthermore, a linear-time variant with stochastic learning is proposed for training LFH on large-scale datasets. Experimental results on two large datasets with semantic labels show that LFH can achieve superior accuracy than state-of-the-art methods with comparable training time.
Using finger-toe pulse oximetry to assess arterial blood flow. (2006)

National guidelines (RCN, 1998; Clinical Resource Efficiency Support Team, 1998; SIGN, 1998) suggest that an assessment of ankle brachial pressure index using Doppler ultrasound is necessary to assess arterial blood flow in patients with leg ulcers or healed ulcers. Robin Cooper describes a newer, more simple test of arterial blood flow using a pulse oximeter, and discusses the advantages and disadvantages of each method.
Maximum Likelihood Estimates of Monotone Parameters (1955)

The maximum likelihood estimators of distribution parameters subject to certain order relations are determined for simultaneous sampling from a number of populations, when $(i)$ the order relations may be specified by regarding the distribution parameters, of which one is associated with each population, as values at specified points of a function of $n$ variables ($n$ a positive integer), monotone in each variable separately; (ii) the distributions of the populations from which sample values are taken belong to the exponential family defined below. This family includes, in particular, the binomial, the normal with fixed standard deviation and variable mean, the normal with fixed mean and variable standard deviation, and the Poisson distributions.

Fully Decentralized Optimal Power Flow of Multi-Area Interconnected Power Systems Based on Distributed Interior Point Method (2017)

Traditionally, the optimal power flow (OPF) problem is solved in a centralized manner. However, with continuous expansion of the scale of multi-area interconnected power systems, realistic applications of the centralized method face additional challenges. In this paper, we propose a fully decentralized OPF algorithm for multi-area interconnected power systems based on the distributed interior point method, where solving the regional correction equation was converted into solving a parametric quadratic programming problem during each Newton-Raphson iteration. This is a novel approach to tackle the decentralized OPF problems. We analyzed the convergence property of this algorithm. The proposed approach is fully decentralized without central coordinator and parameter tuning, and is robust to network partitioning. Furthermore, this decentralized algorithm enjoys the same convergence performance and accuracy as the centralized interior point method. Results on a 3-bus test system, 4 IEEE test systems, and a real 4-area 6056-bus interconnected system show the benefits of the proposed method.
Environmental citizenship and sustainable development: the case of waste facility siting in Taiwan (2008)

Abstract This paper examines how issues of environmental citizenship play out in the context of an industrial waste facility siting controversy in Taipei, Taiwan, and the implications of this complex predicament for justice and sustainable development generally. It shows the ways in which local activists perceive the adverse effects of a development project that generates industrial waste and incinerator ash in their hometown. Local activists feel excluded from decision‐making and frustrated by the lack of recognition by authorities. They complain that their local, contextualized knowledge and experiences are ignored. Local activists are concerned about ecological devastation and feel responsible for future generations. Instead of a NIMBY protest of selfish residents, local activists imagine themselves as active citizens fighting for justice and sustainability on a scale beyond their neighborhood. The case highlights the needs for institutional transparency, the recognition of multiple ways of knowing and new conceptions of the good life.

Testing environment for single‐gene disorders in U.S. reference laboratories (1998)

Molecular diagnosis is the detection of pathogenic mutations in DNA and RNA samples prepared from at-risk patients. Principles underlying DNA-based diagnosis originate from localization and identification of genes responsible for human disease and the characterization of pathogenic mutations; new diagnostic tests are in constant development. Indications for testing include diagnosis, carrier risk revision, prenatal diagnosis, presymptomatic diagnosis, and population screening. The majority of DNA diagnoses are performed in a reference laboratory in which the referring physician, rather that the patient, is the client of the laboratory. Thus, the role of the genetic counselor in a reference laboratory is quite different from traditional clinical practice. As with all clinical laboratory tests, molecular diagnostics are interpreted within the context of the patient's overall clinical presentation and are overlaid with regulatory programs of quality assurance, quality improvement, and quality control. The greatest challenges facing the clinical laboratory are genetic heterogeneity, cost control, regulatory and patent compliance, technology transfer, and the genetic education of the referring physician.

Characterization of single-chain polymer folding using size exclusion chromatography with multiple modes of detection (2014)

We highlight here recent work from our laboratory on the subject of fabricating nanostructures from single polymer chains. These so-called single-chain nanoparticles are synthesized by inducing intra-molecular cross-linking on discrete macromolecules in dilute solution. Among the biggest challenges in this rapidly expanding area of research is reliable and accurate means to characterize this process. In this paper, we review our preferred method of characterization: size exclusion chromatography featuring multiple modes of detection. Multi-angle light scattering in conjunction with a concentration detector can provide absolute molecular weight data; viscometric detection can provide information about solution size and conformation. Correlation of these data provides a simple and robust way to quantify the process by which we fold single polymer coils into architecturally defined unimolecular nanostructures.
