A Soft Decision Detection Method for Run-Length Limited Recording Channels (2005)

This paper describes a soft decision approach to signal detection. The technique is suitable for peak detection with run length limited recording codes in data storage channels that possess an inherent (I-D) term which results in a three state output. The technique requires no algebraic computations, clock generation, high speed sampling or other complex functions associated with detection algorithms based on discrete samples. Conventional pulse slimming and write pre-compensation techniques are employed prior to peak detection to mitigate the effects of intersymbol interference. A practical implementation of this detection concept is suggested and performance is compared with alternate decision schemes in a high speed disk file environment.
Idealized cooling system for further use of computer (2003)

Computer Cooling System (CCS) for an idealized CPU of computer working environment are considered. In own idea, the analysis of CCS has two parts inside the computer. One part is inside of CPU, and the other part is outside of CPU. At present in the computer world, there are many ways to decrease the temperature of computer such as water-cooling system, air cooling system (Fans) and changing the material of the cooler base. In this paper, there is a new idealized cooling system for the environment of outside of CPU has been introduced and I believe this system could solve the working temperature problem of CPU for the further cooling working environment strategy of the computer market.
Idiopathic scoliosis in three dimensions. A radiographic and morphometric analysis (1984)

Eleven articulated scoliotic spines were examined radiographically and morphometrically. Measurement of the curve on anteroposterior radiographs of the specimens gave a mean Cobb angle of 70 degrees, though true anteroposterior radiographs of the deformity revealed a mean Cobb angle of 99 degrees (41% greater). Lateral radiographs gave the erroneous impression that there was a mean kyphosis of 41 degrees while true lateral projections revealed a mean apical lordosis of 14 degrees. Morphometric measurements confirmed the presence of a lordosis at bony level, the apical vertebral bodies being significantly taller anteriorly (P less than 0.02). There were significant correlations (P less than 0.01) between the true size of the lateral scoliosis, the amount of axial rotation and the size of the apical lordosis. This study illustrates the three-dimensional nature of the deformity in scoliosis and its property of changing in character and magnitude according to the plane of radiographic projection.
An Intelligent Broker Architecture for Context-Aware Systems (2002)

Context-aware computing is an emerging paradigm to free everyday users from manually configuring and instructing computer systems. As the general trend of computing is progressing towards an open and dynamic infrastructure, building context-aware systems can be difficult and costly. In order to build successful context-aware systems, we must develop an architecture to reduce the difficulty and cost of building these systems. This PhD. dissertation proposal describes a research plan to develop a broker-centric agent architecture that is aimed to relieve the burden of capability-limited agents of acquiring and reasoning about contexts, and to protect the privacy of users in a contextaware environment. The implementation of the Context Broker Archiecture will explore Web Ontology Language for modeling contexts and privacy policies, Jess for building a hybrid reasoning mechanism and JADE/FIPA for realizing broker behaviors and agent communications.
Wideband low loss double mode SAW filters (2003)

A method is discussed for achieving a wideband low-loss longitudinally coupled double mode surface acoustic wave (SAW) (DMS) filter using a leaky SAW on a 36 degrees Y-X LiTaO/sub 3/ and 64 degrees Y-X LiNbO/sub 3/ substrate with a high electromechanical coupling factor. Its characteristics are analyzed by computer simulation. With the use of the first-mode and third-mode resonance on a 64 degrees Y-X LiNbO/sub 3/ substrate and the selection of the optimum values for the distance between input and output interdigital transducers (IDTs), the electrode film thickness and the input/output IDT pair number, it is possible to achieve favorable characteristics with a 1-dB bandwidth of 33 MHz, and insertion loss of 2.1 dB, and an attenuation in the rejection band of 28 approximately 38 dB.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Multiple-pulse nuclear magnetic resonance of optically pumped xenon in a low magnetic field (1994)

Multiple-pulse coherent averaging methods are used to increase the resolution and frequency range of optically pumped xenon NMR in nutation and point-by-point precession experiments. We observe quadrupolar splittings in $^{131}\mathrm{Xe}$ spectra due to the macroscopic asymmetry of pumping cells similar to those reported previously, but with reduced demands on magnetic-field homogeneity. Cell treatment with hydrogen gas increases the quadrupolar splittings by a factor of 3 over bare Pyrex cells.
Fabrication of Highly <i>b</i>-Oriented MFI Film with Molecular Sieving Properties by Controlled In-Plane Secondary Growth (2010)

Here we report a facile method to fabricate highly b-oriented and submicrometer thin MFI films on substrates. Neither an anhydrous environment nor a specifically designed structure-directing agent (SDA) is required in the whole process, and by innovation of the secondary growth process, twin growth of the b-oriented seed layer is effectively suppressed with TPAOH as the SDA for the first time. Furthermore, various substrates with different surface conditions can be directly used as substrates without premodification. A Pt electrode also was successfully used as a substrate to grow this high quality MFI film, showing excellent molecular sieving ability in aqueous solution.
[Natural history of mitral valve prolapse with respect to the heart size and ventricular arrhythmias]. (1987)

To evaluate the evolution of mitral valve prolapse (MVP) with increasing age, 158 patients were studied by two-dimensional echocardiography and 24-hour ambulatory electrocardiography (Holter monitoring). The patients were divided into seven age groups (25 patients ranging in age from 12 to 14 years, 21 from 15 to 17, 24 from 18 to 20, 24 from 21 to 30, 37 from 31 to 50, 8 from 51 to 60 and 19 older than 61). Each patient was echocardiographically graded as mild, moderate and severe MVP. Ventricular arrhythmia by Holter monitoring was graded as I, II, III and IV according to Lown et al. The following results were obtained. 1. Incidence of moderate and severe MVP was less than 10% in patients younger than 20 years, but increased with age. Incidence of left ventricular dilatation (left ventricular end-diastolic dimension less than or equal to 55 mm) and left atrial dilatation (left atrial dimension greater than or equal to 40 mm) were minimal in patients younger than 20 years, but increased with age, especially in patients older than 51 years. 2. Ventricular couplets or triplets (Lown grade IV) were found in less than 10% in patients in age from 15 to 17 years, 33% in patients from 18 to 20 years and showed no increase with age. The rate of ventricular tachycardia was over 150 beat per min (bpm) in five of nine patients (56%), and the sinus rate preceding ventricular tachycardia was from 65 to 140 bpm.

Sigma-delta modulators and pipeline ADCs are discussed.
Identity Retention of Multiple Objects under Extreme Occlusion Scenarios using Feature Descriptors (2018)

Identity assignment and retention needs multiple object detection and tracking. It plays a vital role in behavior analysis and gait recognition. The objective of Multiple Object Tracking (MOT) is to detect, track and retain identities from an image sequence. An occlusion is a major resistance in identity retention. It is a challenging task to handle occlusion while tracking varying number of person in the complex scene using a monocular camera. In MOT, occlusion remains a challenging task in real world applications. This paper uses Gaussian Mixture Model (GMM) and Hungarian Assignment (HA) for person detection and tracking. We propose an identity retention algorithm using Rotation Scale and Translation (RST) invariant feature descriptors. In addition, a segmentation based optimum demerge handling algorithm is proposed to retain proper identities under occlusion. The proposed approach is evaluated on a standard surveillance dataset sequences and it achieves 97 % object detection accuracy and 85% tracking accuracy for PETS-S2.L1 sequence and 69.7% accuracy as well as 72.3% precision for Town Centre Sequence.
Fluxon Observation Using a Josephson Sampler (1983)

A single fluxon and a bundle of fluxons propagating on a Josephson transmission line are observed by means of the direct coupled Josephson sampler. The half width of the observed pulse is less than 10 ps, and is 6.0 ps under an optimum condition. It is found that the number of fluxons can be controlled by a dc bias current biased at the edge of the transmission line.
Applicability of power-gating strategies for aging mitigation of CMOS logic paths (2014)

Aggressive CMOS technology scaling trends exacerbate the aging-related degradation of propagation delay and energy efficiency in nanoscale designs. Recently, Power-gating has been utilized as an effective low-power design technique which has also been shown to alleviate some aging impacts. However, the use of MOSFETs to realize power-gated designs will also encounter aging-induced degradations in the sleep transistors themselves which necessitates the exploration of design strategies to utilize power-gating effectively to mitigate aging. In particular, Bias Temperature Instability (BTI) which occurs during activation of power-gated voltage islands is investigated with respect to the placement of the sleep transistor in the header or footer as well as the impact of ungated input transitions on interfacial trapping. Results indicate the effectiveness of power-gating on NBTI/PBTI phenomena and propose a preferred sleep transistor configuration for maximizing higher recovery.
The effect of Ni:Co ratio on the elemental phase partitioning in γ-γ′ Ni-Co-Al-Ti-Cr alloys (2017)

Atom probe tomography has been used to characterise the effect of varying Ni:Co ratio on elemental phase partitioning at 800 °C in γ-γ′ alloys derived from the Ni-Co-Al-Ti-Cr system. In all alloys tested, Al and Ti were found to partition preferentially to the γ′ phase, whereas Co and Cr partitioned preferentially to the γ phase. However, above a critical Co content (∼19 at.%), the extent of partitioning of Al and Ti to the γ′ phase reduced. Conversely, Cr partitioned more strongly to the γ phase with Co additions of up to ∼19 at.%, above which this preferential segregation was less pronounced. This non-monotonic trend of elemental partitioning behaviour with increasing Co concentration was attributed to a transition in the chemistry of the L12 γ′ phase from Ni3(Ti, Al) to (Ni, Co)3(Ti, Al) and thus to a change in its solute solubility.
Image interpretation by a single bottom-up top-down cycle (2008)

The human visual system recognizes objects and their constituent parts rapidly and with high accuracy. Standard models of recognition by the visual cortex use feed-forward processing, in which an object's parts are detected before the complete object. However, parts are often ambiguous on their own and require the prior detection and localization of the entire object. We show how a cortical-like hierarchy obtains recognition and localization of objects and parts at multiple levels nearly simultaneously by a single feed-forward sweep from low to high levels of the hierarchy, followed by a feedback sweep from high- to low-level areas.
Sensitive GaAlAs/GaAs wide-gap emitter phototransistor for high current applications (1980)

GaAlAs/GaAs bipolar phototransistors involving a wide gap emitter have been fabricated which exhibit high current gain with corresponding external quantum efficiencies of the order of 5000. The devices provide a power switching capability of more than 1 W.
A Catalytic 2-Aminoethanethiol Reduction on a Gold Electrode through a Sulfur-Gold Bond Formation (2005)

In this note, we report a newly found catalytic reduction of a thiol compound on a gold electrode, which consequently catalyzes the reduction of protons. In a 2-aminoethanethiol solution, no reduction wave was measured with a glassy carbon electrode but a large cathodic wave was observed with a gold electrode indicating a catalytic reduction of a thiol compound at a gold surface. The chemistry involves the adsorption of a self-assembled monolayer (SAM) of 2aminoethanethiol and its reductive desorption reaction. It was reported that an adsorbed self assembled monolayer (SAM) of a thiol compound on the gold electrode surface was reductively desorbed from the surface in alkaline solutions when an appropriate potential was applied. 1-3 The desorbed thiolate anions were electro-deposited again on the gold surface, which is another route to form a thiol monolayer. 4 In other studies by Morin and coworkers, the amount oxidatively re-deposited was affected by the pH of the solution. 5,6 It was suggested that the amount of the redeposition by the oxidation decreases with the increasing solubility of the thiols because of the diffusion into the bulk of the solution. For this study, 2-aminoethanethiol (HSCH2CH2NH3 + ) in a pH 6 aqueous solution, which has not been studied for the reductive desorption reaction, was used as a thiol compound. It has a short chain length with an ionic amino group and is easily dissolved in an aqueous solution. Compared to long chain alkanethiols, it gives less ordered monolayer. 7,8 It is widely employed to give base sites for enzyme layer formations 9-11 and its adsorption was characterized by XPS and electrochemical studies. 12 According to the electrochemical and quartz crystal microbalance measurements of the present study, a catalytic reduction mechanism of a thiol compound is presented here. Figure 1A shows a comparison of the voltammograms with a bare gold plate electrode in a pH 6.0 phosphate buffer in the absence (the dashed line) and presence (the solid line) of 5.0 mM 2-aminoethanethiol. A reduction wave was observed at about −0.7 V in the solution of the 2-aminoethanethiol. In Figure 1B, when a glassy carbon electrode polished with 0.3 µm alumina powder was employed, almost the same two voltammograms in a pure supporting electrolyte (the dashed line) and in a 5.0 mM 2-aminoethanethiol solution (the solid line) were shown. No reduction of the thiol compound was observed with the glassy carbon electrode. The reduction of the 2-aminoethanethiol

A fast three-step phase-shifting algorithm (2005)

We propose a new three-step phase-shifting algorithm, which is much faster than the traditional three-step algorithm. We achieve the speed advantage by using a simple intensity ratio function to replace the arctangent function in the traditional algorithm. The phase error caused by this new algorithm is compensated for by use of a look-up-table (LUT). Our experimental results show that both the new algorithm and the traditional algorithm generate similar results, but the new algorithm is 3.4 times faster. By implementing this new algorithm in a high-resolution, real-time 3D shape measurement system, we were able to achieve a measurement speed of 40 frames per second (fps) at a resolution of 532 × 500 pixels, all with an ordinary personal computer.

Impact of traffic mix on caching performance in a content-centric network (2012)

For a realistic traffic mix, we evaluate the hit rates attained in a two-layer cache hierarchy designed to reduce Internet bandwidth requirements. The model identifies four main types of content, web, file sharing, user generated content and video on demand, distinguished in terms of their traffic shares, their population and object sizes and their popularity distributions. Results demonstrate that caching VoD in access routers offers a highly favorable bandwidth memory tradeoff but that the other types of content would likely be more efficiently handled in very large capacity storage devices in the core. Evaluations are based on a simple approximation for LRU cache performance that proves highly accurate in relevant configurations.
Qualitative Reasoning on Flow Networks (1991)

We discuss qualitative reasoning on flow behavior of complex flow networks. Although most of qualitative reasoning methods use qualitative equations, it is difficult to build such equations for complex flow networks, which often appear in the processing plants. We use the flow network itself as a qualitative model, and consider flow behavior based on the topology of the network without using qualitative equations. It is shown that the flow changes can be determined qualitatively when resistance or voltage of a network with a certain topological structure is disturbed at a point. Flows are modeled generally enough to cover from the most ideal of electric current to gas flows and liquid flows.
Numerical analysis of light propagation in image fibers or coherent fiber bundles (2007)

The coupling properties of multi-core fibers are analyzed using the multipole method and coupled mode theory in order to gain insights into the performance of image fibers that are commonly used in flexible endoscopes. It is explained that coherent fiber bundles with high core density are able to transport images because nonuniformity in the pixel size reduces the inter-core coupling that causes crosstalk. The wavelength, average core size and separation, and degree of core size variation determine the strength of coupling between adjacent cores, such that fibers with a smaller core size and separation at longer wavelengths require more nonuniformity in order for reliable image transmission. Guidelines are given for assessing the performance of image fibers in a particular system.
