Optimization of baud-rate timing recovery for equalization (2002)

This paper suggests the use of a prefilter before baud-rate timing recovery (Mueller and Muller 1976). It is shown that the timing phase of the baud-rate timing synchronizer can be set to a desirable timing phase, at which point a digital equalizer performs best, by proper prefiltering. The procedure for the optimal design of such a prefilter is developed under the assumption that the channel impulse response and desirable timing phase for equalization are known. Application of the proposed scheme to the gigabit Ethernet system demonstrated that prefiltering can improve receiver performance.
Face expression recognition using Local Gabor Binary Pattern Three Orthogonal Planes (LGBP-TOP) and Support Vector Machine (SVM) method (2019)

The video expression recognition system has been created before using the Local Gabor Binary Pattern Three Orthogonal Planes (LGBP-TOP) extraction method and the Support Vector Machine (SVM) classifi-cation method. However, the recognizable facial expressions use the entire area of the face image, while the expression can be recognized from the change of face fiducial point on the eyes and lips only. In this study, the introduction of facial expressions was developed using LGBP-TOP and SVM methods by focusing on facial and lip images only. Therefore, an algorithm is needed to extract the eye and lip area of the face ima-ge using 3x3 blocks and 4x4 blocks, which will then be used as input on the LGBP-TOP method. After the image of the eyes and lips extracted its features, the extraction results are classified using the SVM method. The results obtained is the recognition of facial expressions using the eye and lip area get 80% accuracy and better than using the entire area of the face, eye area only, and lip area only.
Refractive Index as a Basis for Assessing Fatty Acid Composition in Segregating Populations Derived from Infraspecific Crosses of Cultivated Peanuts<sup>1</sup> (1974)

Refractive indexes of oil were converted to calculated iodine values (C.I.V.'s) and used to assess the fatty acid composition of hybrid and segregating populations of six crosses of cultivated peanuts ( Arachis hypogaea L.). Two subspecies ( hypogaea and fastigiata ), three botanical types (Virginia, Spanish, and Valencia), and four market types (Virginia, Southeastern Runner, Spanish, and Valencia) were represented in the four parents. Highly significant statistical effects of locations and genotypes on mean C.I.V.'s were noted. Parent by location interactions were statistically significant, but hybrid by location interactions were nonsignificant. The use of a refractometer as a practical, rapid, inexpensive, and objective means of assessing the fatty acid composition of peanut oil was demonstrated. Significant positive correlation coefficients between C.I.V.'s and the actual linoleic acid compositions of oils from 40 F 2 plants supported the use of the refractometer method. The wide range of genetic variability for C.I.V.'s in F 2 populations of infraspecific crosses indicated selection potential for the improvement of quality and stability of seed oil within specific botanical plant types. C.I.V. appears to be highly heritable, and its expression is controlled by a few additive genes.
Hooray for Hypoxia? (2005)

The mortality of critically ill patients rises steadily as the partial pressure of arterial oxygen falls below about 11 kPa (80 mm Hg). A new animal study in the May 2005 issue of PLoS Biology showing a potential benefit for hypoxia is thus a challenge to current thinking.
Lattice Vector Quantization For Normal Mesh Geometry Coding (2006)

Multiresolution representation of surface meshes is known to be a powerful tool for modeling complex 3D objects. Among the existing schemes, normal meshes have proven to be very attractive for multiresolution and wavelet coding. However, most of the coding methods proposed in the literature are based on scalar quantization despite that vector quantization is known to be more efficient. In this work we propose a novel compression scheme based on a lattice vector quantizer which exploits the correlation inside each geometry subband in a multiresolution framework. Furthermore, we developed a model-based bit allocation algorithm able to work whatever the quantizer is and especially with vector quantization. The proposed scheme allows an improvement up to 1 dB compared to the best state-of-the-art method

Design techniques for dual-passband filters (2005)

This paper introduces two possible approaches to the design of microwave filters presenting two passbands separated by one rejection band, which is created by suitably placing transmission zeros in the stopband. In the first method, the two passbands have almost equal extension and the transmission zeros are symmetrically placed in the stopband; the second method instead allows the synthesis of filters with different passbands width and all the transmission zeros in the stopband placed at the same frequency. Both design methods are based on suitably defined frequency transformations and employ well-established prototype synthesis techniques; the practical implementation is performed through the classical multiple-coupled cavity topology. Two test filters operating in the global system for mobile communication 800-MHz band, designed with the described procedures and actually fabricated, have validated the novel design methods.
Intuitive Broadband Matching Technique for Top-Loaded Monopole Antennas (2019)

Wheeler/Chu's theoretical limit serves as a guideline when designing for the optimum performance of small antennas. It relates the electrical size of the antenna to its quality factor, which can be further related to the bandwidth × efficiency product. Friedman designed a top-loaded monopole that is particularly broadband given its size, but it is not intuitively obvious how to design the matching structure in terms of effective circuit parameters. In this article, we follow Friedman's approach in that we start with designing a matching circuit for a simple top-loaded monopole and obtain performance similar to Friedman's. However, our design is advantageous in two important ways: 1) the circuit is easily understandable and 2) the correspondence between circuit elements and geometrical features on the antenna is clear and straightforward. These advantages may potentially allow this method to be applied to other types of antennas or scaled to different performance parameters.
Ping-pong beam training for reciprocal channels with delay spread (2015)

We present an iterative beam training procedure for a reciprocal channel with delay spread between two massive antenna arrays. The primary application is communication at millimeter wave frequencies. The procedure is based on ping pong transmissions. For each matricial channel coefficient, it tracks the left and right singular vectors associated to the maximal singular value. Based on the set of singular vectors, we build transmit and receive equalizers. A simple equalization based on matched filtering is showed to be optimal in the case of a Gaussian i.i.d. channel and a sparse channel.
Synthesis of Sterols and 5‐Lipoxygenase Products are Required for the G<sub>1</sub>‐S Phase Transition of Interleukin‐2‐Dependent Lymphocyte Proliferation (1987)

A murine killer T cell line, G-CTLL 1, whose proliferation depends on the presence of interleukin 2 (IL-2), was used to analyze the mechanism of IL-2 action with respect to sterol synthesis and arachidonate metabolism. De novo sterol synthesis was substantially enhanced much earlier than DNA synthesis, and the rate reached a maximum at 13 hr after the addition of IL-2. Compactin, which is a potent competitive inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG CoA reductase, the enzyme in the rate-limiting step of the sterol synthesis), inhibited the IL-2-induced DNA synthesis. The addition of mevalonate, the product of HMG CoA reductase, prevented the inhibition of DNA synthesis by compactin, suggesting that the supply of a sufficient amount of sterol is an essential prerequisite for IL-2 action. The IL-2-induced DNA synthesis was also inhibited by AA861, a specific inhibitor of arachidonate 5-lipoxygenase, and by other lipoxygenase inhibitors such as nordihydroguaiaretic acid and esculetin. In contrast, indomethacin, an inhibitor of arachidonate cyclooxygenase, had no effect. These findings suggest that synthesis of 5-lipoxygenase products is also a prerequisite. The inhibition of DNA synthesis was effectively inhibited only when compactin or lipoxygenase inhibitors were added early enough to block the synthesis of sterols or 5-lipoxygenase products; addition of the reagents after 3 hr decreased the inhibition with time. Therefore, about 3 hr after the addition of IL-2, several drastic intracellular changes are assumed to begin and to lead to DNA synthesis.
Transf-ID: Automatic ID and Data Capture for Rail Freight Asset Management (2009)

Accurate tracing at the parts level can play a key role in easing and managing maintenance operations within the railway industry, the same way it streamlines freight operations on more traditional deployments. Transf-ID is an RFID-based tracking system for use in the rail freight industry that will identify cargo and rail vehicles but also mechanical parts that are frequently serviced. The system includes middleware as well as hardware components, combined in an end-to-end solution that translates tag scans into meaningful business events. All tagged items are scanned on the move at checkpoints, leading to valuable information regarding their traveled routes.
Tone Reproduction and Physically Based Spectral Rendering (2002)

The ultimate aim of realistic graphics is the creation of images that provoke the same responses that a viewer would have to a real scene. This STAR addresses two related key problem areas in this effort which are located at opposite ends of the rendering pipeline, namely the data structures used to describe light during the actual rendering process, and the issue of displaying such radiant intensities in a meaningful way. The interest in the first of these subproblems stems from the fact that it is common industry practice to use RGB colour values to describe light intensity and surface reflectancy. While viable in the context of methods that do not strive to achieve true realism, this approach has to be replaced by more physically accurate techniques if a prediction of nature is intended. The second subproblem is that while research into ways of rendering images provides us with better and faster methods, we do not necessarily see their full effect due to limitations of the display hardware. The low dynamic range of a standard computer monitor requires some form of mapping to produce images that are perceptually accurate. Tone reproduction operators attempt to replicate the effect of real-world luminance intensities. This STAR report will review the work to date on spectral rendering and tone reproduction techniques. It will include an investigation into the need for spectral imagery synthesis methods and accurate tone reproduction, and a discussion of major approaches to physically correct rendering and key tone mapping algorithms. The future of both spectral rendering and tone reproduction techniques will be considered, together with the implications of advances in display hardware.
Crowdsourced Learning to Photograph via Mobile Devices (2012)

Capturing a professional photo with high visual quality is always a challenging task for mobile users. This paper presents a crowd sourced learning to photograph approach to assist mobile users for composing high quality photos via their mobile devices. The proposed approach is able to leverage the camera and scene context to search related images with similar context and content from social media communities, and then mine composition knowledge to guide photographing on mobile devices. We develop a patch-based feature generation and selection process to discover salient patches and positions that dominate photo composition aesthetics in the input scene. We then build a regression model to map the composition of salient patches to photo-aesthetic scores. Finally, we develop an efficient hierarchical approach to search for the optimal view enclosure for photograph suggestion. We conducted extensive simulations and subjective evaluations to verify the proposed approach.

This study examines the determinants of positive systemic impact for banks in India.The independent variables considered for the study include the sector, bank size, return on assets, beta, leverage, capital adequacy, non-performing assets, price to book value, deposits, loans & advances, investments, net interest income, and non-interest income.A linear discriminant analysis model was applied in the study.The results of the study indicate that leverage, deposits, loans & advances, investments, return on assets, and non-performing assets are the major discriminators between banks with positive systemic impact and those with non-positive systemic impact.The results of the study also suggest differences in the determinants of positive systemic impact between public sector banks and private sector banks.
Factors Influencing Numbers of <i>Mycobacterium avium</i> , <i>Mycobacterium intracellulare</i> , and Other Mycobacteria in Drinking Water Distribution Systems (2001)

Eight water distribution systems were sampled over an 18-month period (528 water and 55 biofilm samples) to measure the frequency of recovery and number of mycobacteria, particularly Mycobacterium avium and Mycobacterium intracellulare, in raw source waters before and after treatment and within the distribution system. The systems were chosen to assess the influence of source water, treatment, and assimilable organic carbon levels on mycobacterial numbers. Overall, mycobacterial recovery from the systems was low (15% of samples). Numbers of mycobacteria ranged from 10 to 700,000 CFU liter(-1). The number of M. avium in raw waters was correlated with turbidity. Water treatment substantially reduced the number of mycobacteria in raw waters by 2 to 4 log units. Mycobacterial numbers were substantially higher in the distribution system samples (average, 25,000-fold) than in those collected immediately downstream from the treatment facilities, indicating that mycobacteria grow in the distribution system. The increase in mycobacterial numbers was correlated with assimilable organic carbon and biodegradable organic carbon levels (r(2) = 0.65, P = 0.03). Although M. intracellulare was seldom recovered from water samples, it was frequently recovered (six of eight systems) in high numbers from biofilms (average, 600 CFU/cm(2)). Evidently, the ecological niches of M. avium and M. intracellulare are distinct.
Low-power approach for decoding convolutional codes with adaptive viterbi algorithm approximations (2002)

Significant power reduction can be achieved by exploiting real-time variation in system characteristics while decoding convolutional codes.The approach proposed herein adaptively approximates Viterbi decoding by varying truncation length and pruning threshold of the T-algorithm while employing trace-back memory management. Adaptation is performed according to variations in signal-to-noise ratio, code rate, and maximum acceptable bit error rate.Potential energy reduction of 70 to 97.5% compared to Viterbi decoding is demonstrated.Superiority of adaptive T-algorithm decoding compared to fixed T-algorithm decoding is studied.General conclusions about when applications can particularly benefit from this approach are given.

Characterization of H<sub>2</sub> Binding Sites in Prototypical Metal−Organic Frameworks by Inelastic Neutron Scattering (2005)

The hindered rotor transitions of H(2) adsorbed in the chemically related and prototypical porous metal-organic frameworks IRMOF-1, IRMOF-8, IRMOF-11, and MOF-177 were studied by inelastic neutron scattering to gain information on the specifics of H(2) binding in this class of adsorbents. Remarkably sharp and complex spectra of these materials signify a diversity of well-defined binding sites. Similarities in the spectral features as a function of H(2) loading and correlations with recent crystallographic studies were used to assign transitions ranging in rotational barrier from <0.04 to 0.6 kcal/mol as corresponding to localized adsorption sites on the organic and inorganic components of these frameworks. We find that binding of H(2) at the inorganic cluster sites is affected by the nature of the organic link and is strongest in IRMOF-11 in accord with our adsorption isotherm data. The sites on the organic link have lower binding energies, but a much greater capacity for increases in H(2) loading, which demonstrates their importance for hydrogen uptake by these materials.
A software approach to multiprocessor address trace generation (2002)

The authors describe a technique for generating architecture-independent multiprocessor data address traces on a widely available RISC (reduced instruction set computer) uniprocessor for a specific class of parallel applications. Automatic modification of the application assembly language enables run-time recording of the virtual address and data for loads and stores. Barrier synchronization events are captured in the traces. The tracing technique (called the Tracer) is relatively fast, portable, and does not require access to a multiprocessor. The generality of the traces and the slow-down by a factor of 10 when generating traces compares favourably with other address tracing methods. The Tracer has proved useful in the evaluation of a hierarchical shared bus multiprocessor. The Tracer can be used to gather statistics on programs for use in stochastic models such as queuing networks. Additionally, the visualization of memory access patterns that can be made with the traces is a useful tool in studying parallel applications on shared memory multiprocessors.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Fiber Optic Force Sensor for Medical Applications within a Backbone-shape Structure (2013)

In recent years, the needs of force measurement in medicine are becoming stronger to realize further effective treatments and quantitative assessments. For example, quantitative safety assessment can be realized by introducing such force sensors by monitoring the interaction force on the conventional medical devices - such as surgical knife or forceps, to the organs. In addition, as force information is significantly deteriorated in the domain of Minimally Invasive Surgery (MIS) due to the discrepancy of eye- hand coordination and frictions of MIS devices through the body incision holes, the surgeons must perform the surgery in obtaining the force information alternatively from the vision through endoscope. Therefore, such force sensors potentially play a key role for the surgery with further quantitative assessments. From these backgrounds, we propose a new force sensor using fiber optic that is compatible with medical applications. Fiber Bragg Grating (FBG) enables force measurement in the long axis of the fiber by measuring the wavelength shift of spectral response of light source. In contrast with conventional force measurement methods such as strain gauge, FBG sensor does not emit any electric noise, either be influenced. The presented backbone shape allay force sensor using FBG fiber optic was developed to realize a bending force sensing in a compact stick shape implementation with the capability of sterilization, temperature compensation and output amplification. In this paper, the sensor structure, mechanical principle, prototype implementation and evaluations are descried.
Node architecture and protocol of a packet-switched dense WDMA metropolitan area network (1999)

This paper proposes a new node architecture and protocol for a wavelength division multiple access (WDMA) packet-switched metropolitan area network. The network operates on a dual-bus topology and the tunable-transmitter and fixed-receiver scheme is adopted to facilitate data multiaccess. The network protocol runs on a cycle mechanism and the cycle length can be adaptively changed according to the data traffic, thus provides high throughput. The photonic implementation of the proposed network architecture and network nodes is discussed and a new packet-signaling scheme is proposed to avoid data collision during multiaccess. An experimental demonstration is also presented to show its feasibility.
