Intent Determination and Spoken Utterance Classification (2011)

Spoken language understanding (SLU) is an emerging field in between speech and language processing, investigating human/ machine and human/ human communication by leveraging technologies from signal processing, pattern recognition, machine learning and artificial intelligence. SLU systems are designed to extract the meaning from speech utterances and its applications are vast, from voice search in mobile devices to meeting summarization, attracting interest from both commercial and academic sectors. Both human/machine and human/human communications can benefit from the application of SLU, using differing tasks and approaches to better understand and utilize such communications. This book covers the state-of-the-art approaches for the most popular SLU tasks with chapters written by well-known researchers in the respective fields. Key features include: Presents a fully integrated view of the two distinct disciplines of speech processing and language processing for SLU tasks. Defines what is possible today for SLU as an enabling technology for enterprise (e.g., customer care centers or company meetings), and consumer (e.g., entertainment, mobile, car, robot, or smart environments) applications and outlines the key research areas. Provides a unique source of distilled information on methods for computer modeling of semantic information in human/machine and human/human conversations. This book can be successfully used for graduate courses in electronics engineering, computer science or computational linguistics. Moreover, technologists interested in processing spoken communications will find it a useful source of collated information of the topic drawn from the two distinct disciplines of speech processing and language processing under the new area of SLU.
Energy Efficient Millimeter Wave Radio Link Establishment with Smart Array Antenna | NIST (2006)

Abstract : Consider a system of two millimeter wave transceiver nodes A and B. We assume that each node is equipped with a circular array antenna that has beamforming capability. We are interested in using the beamforming capability to find the best possible directions for transmission and reception such that the communication link between two nodes provides maximal SNR at the receiver. A protocol that in most cases achieves the optimal solution is developed and simulation results are provided to show the effectiveness of the algorithm.
Graphene frequency doubler with record 3GHz bandwidth and the maximum conversion gain prospects (2012)

We report a 500nm graphene field-effect transistor operating at the Dirac point for frequency doubling with maximum output power of −23dBm and a record bandwidth of 3GHz, 2× higher than the state-of-the-art. The experimental device exceeds its f <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">t</inf> and f <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">max</inf> by about 50%.

In the limit of negligible non-idealities and maximum gate capacitance, the conversion gain approaches lossless frequency doubling.

100BASE-T2: a new standard for 100 Mb/s Ethernet transmission over voice-grade cables (1997)

100BASE-T2 is a new physical-layer specification for IEEE 802.3 LANs operating at 100 Mb/s ("Fast Ethernet"). It enables users of the prevailing 10BASE-T Ethernet LAN technology to upgrade their networks from 10 to 100 Mb/s performance while retaining an existing voice-grade cabling infrastructure. 100BASE-T2 transceivers will operate over two pairs in unshielded twisted-pair cables corresponding to EIA/TIA category 3 (UTP-3), as minimally required for 10BASE-T. In a four-pair UTP-3 cable, simultaneous operation of two 100BASE-T2 links, or one 100BASE-T2 and one 10BASE-T link, is permitted. Since voice-grade cables exhibit more signal attenuation and significantly higher crosstalk coupling between adjacent pairs than data-grade cables, sophisticated digital signal processing techniques are needed to achieve reliable duplex 100 Mb/s transmission over two pairs. The 100BASE-T2 standard defines dual-duplex baseband transmission at a modulation rate of 25 Mbaud. During each modulation interval, a four-bit data nibble or Ethernet-specific control information is encoded into a pair of quinary signals. These signals are transmitted simultaneously on the two wire pairs in both signaling directions. In the receivers, adaptive digital filters are required for echo and NEXT cancellation, equalization, and interference suppression.

Nonuniform Liouville transformers for quasi-homogeneous optical fields. Final technical report, September 25, 1989--January 22, 1993 (1993)

During the last two decades, there have been dramatic improvements in the development of optical sources. Examples of this development range from semiconductor laser diodes to free electron beam lasers and synchrotron radiation. Before these developments, standards for the measurement of basic optical parameters (quantities) were less demanding. Now, however, there is a fundamental need for new, reliable methods for providing fast quantitative results for a very broad variety of optical systems and sources. This is particularly true for partially coherent optical beams, since all optical sources are either fully or partially spatially coherent (including Lambertian sources). Until now, there has been no satisfactory solution to this problem. During the last two decades, however, the foundations of physical radiometry have been developed by Walther, Wolf and co-workers. By integrating physical optics, statistical optics and conventional radiometry, this body of work provides necessary tools for the evaluation of radiometric quantities for partially coherent optical beams propagating through optical systems. In this program, Physical Optics Corporation (POC) demonstrated the viability of such a radiometric approach for the specific case of generalized energy concentrators called Liouville transformers. We believe that this radiometric approach is necessary to fully characterize any type of optical system since it takes into account the partial coherence of radiation. 90 refs., 57 figs., 4 tabs.
Surfing Motility: a Conserved yet Diverse Adaptation among Motile Bacteria (2018)

Bacterial rapid surfing motility is a novel surface adaptation of <i>Pseudomonas aeruginosa</i> in the presence of the glycoprotein mucin. Here, we show that other Gram-negative motile bacterial species, including <i>Escherichia coli</i>, <i>Salmonella enterica</i>, <i>Vibrio harveyi</i>, <i>Enterobacter cloacae</i>, and <i>Proteus mirabilis</i>, also exhibit the physical characteristics of surfing on the surface of agar plates containing 0.4% mucin, where surfing motility was generally more rapid and less dependent on medium viscosity than was swimming motility. As previously observed in <i>Pseudomonas aeruginosa</i>, all surfing species exhibited some level of broad-spectrum adaptive resistance, although the antibiotics to which they demonstrated surfing-mediated resistance differed. Surfing motility in <i>P. aeruginosa</i> was found to be dependent on the quorum-sensing systems of this organism; however, this aspect was not conserved in other tested bacterial species, including <i>V. harveyi</i> and <i>S. enterica</i>, as demonstrated by assaying specific quorum-sensing mutants. Thus, rapid surfing motility is a complex surface growth adaptation that is conserved in several motile bacteria, involves flagella, and leads to diverse broad-spectrum antibiotic resistance, but it is distinct in terms of dependence on quorum sensing.<b>IMPORTANCE</b> This study showed for the first time that surfing motility, a novel form of surface motility first discovered in <i>Pseudomonas aeruginosa</i> under artificial cystic fibrosis conditions, including the presence of high mucin content, is conserved in other motile bacterial species known to be mucosa-associated, including <i>Escherichia coli</i>, <i>Salmonella enterica</i>, and <i>Proteus mirabilis</i> Here, we demonstrated that key characteristics of surfing, including the ability to adapt to various viscous environments and multidrug adaptive resistance, are also conserved. Using mutagenesis assays, we also identified the importance of all three known quorum-sensing systems, Las, Rhl, and Pqs, in <i>P. aeruginosa</i> in regulating surfing motility, and we also observed a conserved dependence of surfing on flagella in certain species.

31P-nuclear magnetic resonance analysis of perfused single frog skins (1985)

Perfusion of single frog skins has produced stability of the 31P-nuclear magnetic resonance (NMR) spectra over periods as long as 8 h at room temperature. With this approach, relatively large phosphocreatine (PCr) signals were recorded for each of the 12 frog skins studied. The ratio of the concentration of PCr to ATP was estimated to be 0.76 +/- 0.07, a value an order of magnitude larger than that previously reported. Comparison of the ratio of the intracellular concentrations of inorganic phosphate (Pi) to ATP determined in the present NMR study with that previously estimated by chemical analysis suggests that little intracellular Pi is likely to be immobilized. Inclusion of methylphosphonate in the perfusing solutions permitted simultaneous determination of extracellular and intracellular pH from the NMR spectra alone. The methylphosphonate has been found to be nontoxic. At an extracellular pH of 7.72 +/- 0.04, the intracellular pH was 7.47 +/- 0.06.
ZVS Turn-on integrated Triangular Current Mode Three-phase PFC for EV On-board Chargers (2022)

An efficient, compact and lightweight three-phase AC-DC power factor correction (PFC) converter becomes a necessity for electric vehicles (EVs) On-board chargers (OBCs) in conventional grid-to-vehicle (G2V) and vehicle-to-grid (V2G) charging methods. The commercially available OBCs have very limited power density despite the moderate efficiency under specific power levels. In this paper, the integrated triangular current mode (iTCM) control is implemented to improve the power density (kW/L) and specific power (kW/kg) of the three-phase PFC converter stage while maintaining high efficiency. Zero voltage switching (ZVS) turn-on is realized in the iTCM control with a higher switching frequency to reduce the LCL filter size without sacrificing efficiency. By adding an LC branch between the bridge leg and mid-point of the DC link, the high-frequency and low-frequency currents are split to minimize the inductor loss and to derive a better inductor design. Analytical modeling and simulation in PLECS are conducted to verify the idea of iTCM. The capacitor-current feedback active damping method is implemented to prevent instability from the LC and LCL filters. The design of an 11kW three-phase AC-DC PFC converter, including the input LCL filter, achieves an efficiency of 98.81%, a power density of 12.46 kW/L and a specific power per weight of 1.87 kW/kg. The proposed three-phase iTCM control is benchmarked in a 3 kW SiC MOSFET-based AC-DC converter.
Ultrashort (/spl les/150 fs) carrier relaxation time of intersubband transition in AlGaN/GaN multiple quantum wells (2000)

Summary form only given. Intersubband transition (ISBT) in semiconductor multiple quantum wells (MQWs) is a promising phenomenon for realizing, ultrafast optoelectronic devices because of the very short relaxation time. Above all, the relaxation time of the ISBT in AlGaN-GaN MQWs is theoretically predicted to be 100 fs or shorter, due to strong coupling of electrons with the longitudinal (LO) phonons. In this study, we experimentally demonstrated the ultrafast relaxation process due to ISBT in Al/sub 0.65/Ga/sub 0.35/N-GaN MQWs by a pump-probe measurement. A theoretical fit indicated that the relaxation time is shorter than 150 fs at a wavelength of 4.6 /spl mu/m.
WDM/FDM star coupler with gain using fibre amplifiers (1993)

An efficient amplified WDM/FDM star coupler is proposed. The size of the coupler can be increased by a factor of m using m fibre amplifiers. Furthermore, the complexity and cost of the proposed scheme are less than those of other configurations.
Enhancement of organ of interest via background subtraction in cone beam rotational angiocardiogram (2012)

The real time X-ray angiography based on C-arm cone beam system is the workhorse imaging modality for interventional cardiac procedures. These images are two-dimensional (2D) projections of three dimensional (3D) objects along the X-ray direction. The organ of interest (OOI), such as left ventricle (LV) endocardium, in the projection image is superimposed with other anatomical structures and often has low contrast. In this study, a novel approach is proposed to isolate the OOI in projection images by subtracting with a background image, which is generated by numerical projection of 3D tomographic image with OOI masked out. Study based on one patient and one pig image is taken. About two to three-fold increase in the contrast-to-noise ratio (CNR) is achieved for LV endocardium, compared to an unprocessed image.
Accessibility Experience Lab: Discovering the Impact of Design on Disabilities (2010)

Many accessibility problems of devices and user interfaces could be avoided if the needs of people with disabilities were considered during the design process. This paper describes an accessibility experience lab module which introduces participants to both the barriers associated with disabilities and the impact that simple design changes can have on those barriers. The core of the lab is an experience session where participants are given functional limitations along with tasks at paired stations so they can compare their experiences on devices with inaccessible and accessible designs. For seven years the experience lab has been a part of the curriculum for first-year engineering students at the University of Wisconsin, and over 1700 students have completed it. In the popular lab, the students are engaged and report interest and insights into design for disabilities. Materials are available at www.trace.wisc.edu/training/explab/ .
Model‐based analyses of bioequivalence crossover trials using the stochastic approximation expectation maximisation algorithm (2011)

In this work, we develop a bioequivalence analysis using nonlinear mixed effects models (NLMEM) that mimics the standard noncompartmental analysis (NCA). We estimate NLMEM parameters, including between-subject and within-subject variability and treatment, period and sequence effects. We explain how to perform a Wald test on a secondary parameter, and we propose an extension of the likelihood ratio test for bioequivalence. We compare these NLMEM-based bioequivalence tests with standard NCA-based tests. We evaluate by simulation the NCA and NLMEM estimates and the type I error of the bioequivalence tests. For NLMEM, we use the stochastic approximation expectation maximisation (SAEM) algorithm implemented in monolix. We simulate crossover trials under H(0) using different numbers of subjects and of samples per subject. We simulate with different settings for between-subject and within-subject variability and for the residual error variance. The simulation study illustrates the accuracy of NLMEM-based geometric means estimated with the SAEM algorithm, whereas the NCA estimates are biased for sparse design. NCA-based bioequivalence tests show good type I error except for high variability. For a rich design, type I errors of NLMEM-based bioequivalence tests (Wald test and likelihood ratio test) do not differ from the nominal level of 5%. Type I errors are inflated for sparse design. We apply the bioequivalence Wald test based on NCA and NLMEM estimates to a three-way crossover trial, showing that Omnitrope®; (Sandoz GmbH, Kundl, Austria) powder and solution are bioequivalent to Genotropin®; (Pfizer Pharma GmbH, Karlsruhe, Germany). NLMEM-based bioequivalence tests are an alternative to standard NCA-based tests. However, caution is needed for small sample size and highly variable drug.
Prototyping a high availability PaaS: Performance analysis and lessons learned (2017)

With cloud computing consolidation, Platform-as-a-Service (PaaS) has been used as a solution for developing applications with low cost and maximum flexibility. However, an open challenge related to PaaS is the proper handling of multi-tier and stateful applications with support for high availability (HA); and scalability can be considered an essential feature for HA. However, dealing with several instances of the same application that access its state in a common area is not a simple task. This paper presents a novel PaaS framework, named NoPaaS, that supports the deployment of multi-tier and stateful applications assuring their availability according to the Service Availability Forum (SAF) redundancy model. The primary goal of this work is to present NoPaaS framework and prototype, and highlight challenges and open issues when providing multi-tier and stateful applications in high availability clouds.
A novel technique for detecting lithographic defects (1988)

This method uses accelerated electrolytic etching of metal by photoresist developer, and therefore permits developing and etching in one solution, eliminating the need for two separate process steps. This procedure is the key to identifying strictly lithographic defects, and is applied to the verification of the voting lithography scheme. Defects were deliberately introduced on masks used in these experiments. Almost complete elimination of these defects on wafer patterns is achieved using vote-taking lithography.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Damage-free pinpoint particle removal for EUV pellicle cleaning (2022)

An extreme ultraviolet (EUV) pellicle is employed to prevent contamination on a EUV mask. The EUV pellicle, a high-priced membrane, gets contaminated during both the fabrication process and exposure. The lifetime of the pellicle can be extended by the removal of these contaminants. In this study, a particle removal technique for the EUV pellicle was developed. A functionalized atomic force microscopy (AFM) probe and programable particle contamination system were developed for particle removal and evaluation of the technique, respectively. The particle was removed with a pinpoint technique and the inherent vibration of the free-standing membrane was suppressed during the process. The process window of the proposed pinpoint cleaning technique was investigated to ensure damage-free particle removal and the nanomanipulated functionalized probe resulted in efficient particle removal from the pellicle surface without damage.
Scheduling-assisted joint processing for CoMP in the framework of the WINNER+ project (2010)

The goal of this paper is to present the main achievements reached within the WINNER+ project concerning, in particular, clustering as a way to improve the\nfeasibility of joint processing schemes as enablers of coordinated multipoint solutions. Three different approaches are presented. First, a single and static cluster of base stations is considered. In this case, a user-centric partial joint processing scheme is\nproposed to reduce with respect to a fully centralized approach both the inter-base information exchange and feedback from the users. Second, a dynamic and network centric clustering approach is presented. It is shown that substantial gains can be obtained with respect to a static clustering scenario when a central unit jointly creates\nthe clusters of collaborating base stations, schedules the users in these clusters and calculates the beamforming coefficients and the power allocation. Finally, a dynamic\nclustering technique is combined with multi-antenna receivers. In addition, a concept for a scalable channel state information feedback is also presented.
Optimizing Floating Point Units in Hybrid FPGAs (2011)

This paper introduces a methodology to optimize coarse-grained floating point units (FPUs) in a hybrid field-programmable gate array (FPGA), where the FPU consists of a number of interconnected floating point adders/subtracters (FAs), multipliers (FMs), and wordblocks (WBs). The wordblocks include registers and lookup tables (LUTs) which can implement fixed point operations efficiently. We employ common subgraph extraction to determine the best mix of blocks within an FPU and study the area, speed and utilization tradeoff over a set of floating point benchmark circuits. We then explore the system impact of FPU density and flexibility in terms of area, speed, and routing resources. Finally, we derive an optimized coarse-grained FPU by considering both architectural and system-level issues. This proposed methodology can be used to evaluate a variety of FPU architecture optimizations. The results for the selected FPU architecture optimization show that although high density FPUs are slower, they have the advantages of improved area, area-delay product, and throughput.
Enhancing image classification models with multi-modal biomarkers (2011)

Currently, most computer-aided diagnosis (CAD) systems rely on image analysis and statistical models to diagnose, quantify, and monitor the progression of a particular disease. In general, CAD systems have proven to be effective at providing quantitative measurements and assisting physicians during the decision-making process. As the need for more flexible and effective CADs continues to grow, questions about how to enhance their accuracy have surged. In this paper, we show how statistical image models can be augmented with multi-modal physiological values to create more robust, stable, and accurate CAD systems. In particular, this paper demonstrates how highly correlated blood and EKG features can be treated as biomarkers and used to enhance image classification models designed to automatically score subjects with pulmonary fibrosis. In our results, a 3-5% improvement was observed when comparing the accuracy of CADs that use multi-modal biomarkers with those that only used image features. Our results show that lab values such as Erythrocyte Sedimentation Rate and Fibrinogen, as well as EKG measurements such as QRS and I:40, are statistically significant and can provide valuable insights about the severity of the pulmonary fibrosis disease.
