Impact of VLSI design rules on high voltage (2000 V) IGBTs/ESTs (2002)

MOS-gated bipolar devices are rapidly replacing traditional bipolar devices in increasingly higher voltage regimes. The advantages of MOS-gate control and current saturation capability make the IGBT and the dual channel emitter switched thyristor (DC-EST) most likely to replace the GTO in the 2-4 kV voltage regime. However, power device design still lags behind CMOS design in utilizing the better design rules that are easily attainable with current processing technology at reasonable cost. Furthermore, the advantages that can be achieved by moving towards thinner gate oxides have not yet been fully realized in power devices. In this paper, extremely low forward drop, high voltage IGBTs and DC-ESTs are experimentally demonstrated using VLSI design rules for the first time. It is shown that conventional planar processing technology coupled with superior design rules and thinner gate oxides can lead to extremely wide forward bias SOA (FBSOA).
View invariant human action recognition using histograms of 3D joints (2012)

In this paper, we present a novel approach for human action recognition with histograms of 3D joint locations (HOJ3D) as a compact representation of postures. We extract the 3D skeletal joint locations from Kinect depth maps using Shotton et al.'s method [6]. The HOJ3D computed from the action depth sequences are reprojected using LDA and then clustered into k posture visual words, which represent the prototypical poses of actions. The temporal evolutions of those visual words are modeled by discrete hidden Markov models (HMMs). In addition, due to the design of our spherical coordinate system and the robust 3D skeleton estimation from Kinect, our method demonstrates significant view invariance on our 3D action dataset. Our dataset is composed of 200 3D sequences of 10 indoor activities performed by 10 individuals in varied views. Our method is real-time and achieves superior results on the challenging 3D action dataset. We also tested our algorithm on the MSR Action 3D dataset and our algorithm outperforms Li et al. [25] on most of the cases.
Successive approximation vector quantization (1986)

Abstract This paper presents a new “ordering” based suboptimal vector quantization, the successive approximation vector quantization (SAVQ). It is found that the SAVQ algorithm can be reduced to the bit arrangement mapping from vector to scalar followed by the scalar quantization. Therefore the SAVQ requires no calculation of distortion. However, the tree search vector quantization (TSVQ), another suboptimal VQ, does require calculation of distortion. This allows the real time vector quantizer to be implemented with significantly less hardware complexity than TSVQ. For the source with exponential density, the simulation results demonstrate that SAVQ provides the mean‐squared‐error equal to or less than that obtained by TSVQ.
Physical-layer identification of wireless sensor nodes (2012)

Identification of wireless sensor nodes based on the physical characteristics of their radio transmissions can potentially provide additional layer of security in all-wireless multi-hop sensor networks. Reliable identification can be means for detection and/or prevention of wormhole, Sybil and replication attacks, and for complementing cryptographic message authentication protocols. In this paper, we propose an improved method for capturing and analysis of sensor node radio signals for reliable and accurate recognition. We investigate the performance accuracy of our approach in terms of parameters such as distance, antenna polarization, voltage and show that it achieves recognition with EER=0.24%. We also propose and perform practical attacks on the recognition to further evaluate the robustness of the proposed method under security threats.
The $25,000,000,000 Eigenvector: The Linear Algebra behind Google (2006)

Google's success derives in large part from its PageRank algorithm, which ranks the importance of web pages according to an eigenvector of a weighted link matrix. Analysis of the PageRank formula provides a wonderful applied topic for a linear algebra course. Instructors may assign this article as a project to more advanced students or spend one or two lectures presenting the material with assigned homework from the exercises. This material also complements the discussion of Markov chains in matrix algebra. Maple and Mathematica files supporting this material can be found at www.rose-hulman.edu/~bryan.
Improved Safety of Rig Automation with Remote Monitoring and Diagnostics (2004)

Abstract Rig automation has focused on improving safety with equipment designed to reduce manpower/human interaction and assume repetitive tasks and operations. As more parts of a drilling rig become automated, there has been a change in how rig personnel interact with equipment. A system of remote monitoring, diagnostics and technical support has been developed to make this interaction more seamless and expand the focus of rig automation. Case studies are presented in this paper of actual field conditions where the remote monitoring system eliminated hazardous operations, discovered operational "bad habits", and identified areas requiring additional training. Use of the remote diagnostic system prevented the need for physical contact between human and machine in order to solve problems. Documented field incidents have shown benefits of increased safety in many areas when using remote monitoring and management compared to operations without.
Phenotypic and Phylogenetic Characterization of Ruminal Tannin-Tolerant Bacteria (1998)

The 16S rRNA sequences and selected phenotypic characteristics were determined for six recently isolated bacteria that can tolerate high levels of hydrolyzable and condensed tannins. Bacteria were isolated from the ruminal contents of animals in different geographic locations, including Sardinian sheep (Ovis aries), Honduran and Colombian goats (Capra hircus), white-tail deer (Odocoileus virginianus) from upstate New York, and Rocky Mountain elk (Cervus elaphus nelsoni) from Oregon. Nearly complete sequences of the small-subunit rRNA genes, which were obtained by PCR amplification, cloning, and sequencing, were used for phylogenetic characterization. Comparisons of the 16S rRNA of the six isolates showed that four of the isolates were members of the genus Streptococcus and were most closely related to ruminal strains of Streptococcus bovis and the recently described organism Streptococcus gallolyticus. One of the other isolates, a gram-positive rod, clustered with the clostridia in the low-G+C-content group of gram-positive bacteria. The sixth isolate, a gram-negative rod, was a member of the family Enterobacteriaceae in the gamma subdivision of the class Proteobacteria. None of the 16S rRNA sequences of the tannin-tolerant bacteria examined was identical to the sequence of any previously described microorganism or to the sequence of any of the other organisms examined in this study. Three phylogenetically distinct groups of ruminal bacteria were isolated from four species of ruminants in Europe, North America, and South America. The presence of tannin-tolerant bacteria is not restricted by climate, geography, or host animal, although attempts to isolate tannin-tolerant bacteria from cows on low-tannin diets failed.
Solid-Phase Synthesis of Naltrindole Derivatives Using Fischer Indole Synthesis Based on One-Pot Release and Cyclization Methodology (2003)

[reaction: see text] We describe a new approach for the solid-phase synthesis of indoles 1 that involves a one-pot release and cyclization reaction of a solid-supported hydrazone through a Wang-type linker. Using this solid-phase methodology, we accomplished the synthesis of 40 naltrindole derivatives.

Machine learning assisted optimization of electrochemical properties for Ni-rich cathode materials (2018)

Optimizing synthesis parameters is the key to successfully design ideal Ni-rich cathode materials that satisfy principal electrochemical specifications. We herein implement machine learning algorithms using 330 experimental datasets, obtained from a controlled environment for reliability, to construct a predictive model. First, correlation values showed that the calcination temperature and the size of the particles are determining factors for achieving a long cycle life. Then, we compared the accuracy of seven different machine learning algorithms for predicting the initial capacity, capacity retention rate, and amount of residual Li. Remarkable predictive capability was obtained with the average value of coefficient of determinant, R<sup>2</sup> = 0.833, from the extremely randomized tree with adaptive boosting algorithm. Furthermore, we propose a reverse engineering framework to search for experimental parameters that satisfy the target electrochemical specification. The proposed results were validated by experiments. The current results demonstrate that machine learning has great potential to accelerate the optimization process for the commercialization of cathode materials.

Distribution system outage and restoration analysis using a wireless AMR system (2003)

The advances in computer applications and technology are providing more and more data about the distribution system that can be used for analysis. One new technology is automated meter reading (AMR) systems. AMR systems provide access to the consumption and status of individual customers. This summary outlines research work to incorporate AMR information in outage management The first technique combines AMR data with SCADA and trouble call data to identify an outage and then uses AMR polling to verify the outage and its level. The second technique provides a way to use AMR to confirm restoration of all customers below an outaged device.
Identification of functional paralog shift mutations: Conversion of <i>Escherichia coli</i> malate dehydrogenase to a lactate dehydrogenase (2007)

Five positions in the Escherichia coli malate dehydrogenase (eMDH) sequence, which distinguish MDH from lactate dehydrogenase (LDH) activity, were identified through a combination of Venn diagrams constructed from whole genomic data and from unbiased representative sequences from terminal clades. Incorporation of the five changes in eMDH sufficed to convert the enzyme from one with (k(cat)/K(m)(pyruvate))/(k(cat)/K(m)(oxaloacetate)) = 6.1 x 10(-9) to one with that ratio = 28. The substrate specificity was thus changed by a factor of 4.6 x 10(9). The k(cat)/K(m)(pyruvate) value for the pentamutant (eMDH I12V/R81Q/M85E/G210A/V214I) is 3,500 M(-1).s(-1), which is approximately equal 1/1,000 of the values found for typical wild-type LDHs. The procedure isolates an intersection of "strong forcing sets" that should prove to be of general use in switching paralog function.
Sensing strategies for disambiguating among multiple objects in known poses (1986)

The need for intelligent interaction of a robot with its environment frequently requires sensing of the environment. Further, the need for rapid execution requires that the interaction between sensing and action take place using as little sensory data as possible, while still being reliable. Previous work has developed a technique for rapidly determining the feasible poses of an object from sparse, noisy, occluded sensory data. Techniques for acquiring position and surface orientation data about points on the surfaces of objects are examined with the intent of selecting sensory points that will force a unique interpretation of the pose of the object with as few data points as possible. Under some simple assumptions about the sensing geometry, we derive a technique for predicting optimal sensing positions. The technique has been implemented and tested. To fully specify the algorithm, estimates of the error in estimating the position and orientation of the object are needed. Analytic expressions for such errors in the case of one particular approach to object recognition are derived.

Sandboxing in Linux: From Smartphone to Cloud (2016)

In today's internet world, Malicious and malfunctioning contents from the internet are regular problems for host systems such as Smartphones, Desktops, Clouds etc. Almost all underlying operating systems provide security from most of the threats. However, we need to add some extra defense to our system. Sandboxing is an important security technique that lets programs run in its isolated environment. A sandbox is a tightly controlled environment where programs run. It provides access to a tightly controlled set of resources for programs, such as memory, scratch space on the disk, network access, and input devices. A program running in the sandbox has just as many permissions as it needs without having additional permissions that could be misused. Sandbox restricts a program to access resources outside the sandbox. Sandbox prevents malicious or malfunctioning programs from accessing rest of the system. Nowadays, most of the mobile operating systems, desktop applications like web browsers, browser plugins, document viewers and cloud computing systems are using sandboxing mechanism to run applications. For the implementation of the sandboxing mechanism, software vendors rely on underlying operating system security features. There are different ways and approaches that can be used to implement sandbox mechanisms. This paper highlights the Linux security features such as Chroot, Cgroups, Capabilities, SCI, Namespaces, Seccomp, Resource Limit, LSMs such as SELinux, Virtualization and grsecurity that can be used in the implementation of the sandboxing mechanism.

Measuring the Parity of an<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi>N</mml:mi></mml:math>-Qubit State (2005)

We present a scheme for a projective measurement of the parity operator Pz = Product(N)i=1 sigma(i)z of N qubits. Our protocol uses a single ancillary qubit, or a probe qubit, and involves manipulations of the total spin of the N qubits without requiring individual addressing. We illustrate our protocol in terms of an experimental implementation with atomic ions in a two-zone linear Paul trap, and further discuss its extensions to several more general cases.
A review of SAR speckle filters: texture restoration and preservation (2002)

Speckle filtering is probably one of the important steps in post SAR (synthetic aperture radar) image processing. Speckle appears in all SAR products including single-polarimetric, multipolarimetric and interferometric image data. Many speckle filtering algorithms have been proposed aimed at speckle reduction. Texture, revealing the spatial-dependent information in images, may be as important as other polarimetric measures. Such information is not expected being distorted and degraded during speckle suppression. This paper examines various speckle filters including the Lee, Frost, Kuan and other filters in terms of texture preservation. The first and second order texture measures are used in the assessment.
Recursive channel estimation for wireless communication via the EM algorithm (2002)

The on-line expectation-maximization (EM) algorithm along with stochastic approximations are employed in this paper to estimate unknown time-invariant/variant parameters recursively in an adaptive manner based on the maximum likelihood (ML) criterion. The impulse response of a linear transmission channel is modeled in different ways; as an unknown deterministic vector/process and as an Gaussian vector/process with unknown stochastic characteristics. In association with these channel impulse response (CIR) models, different types of recursive least squares (RLS) and Kalman filtering and smoothing algorithms are derived directly from the on-line EM algorithm. The EM algorithm as a powerful tool unifies the derivations of some adaptive estimation methods (which include RLS and Kalman) whose original criterion is minimum mean square error (MMSE), but under linear and Gaussian conditions can achieve ML or maximum a posterior (MAP) criterion.
Coaxing graphene to be piezoelectric (2012)

Several exotic characteristics and properties have made graphene a well-studied material from both a basic science viewpoint as well as tantalizing applications ranging from nanoelectronics, gas separation membranes to ultracapacitors. Graphene, however, is non-piezoelectric. This is obvious when graphene is in its metallic or semi-metallic state. However, even when graphene is in dielectric form—which can be engineered through porosity or by using nanoribbons—graphene is non-piezoelectric due to its centrosymmetric crystal structure. Using quantum mechanical calculations, we show that merely by creating holes of the right symmetry, graphene can be coaxed to act as a piezoelectric. We find that certain specifically tailored porous graphene sheets can “acquire” piezoelectricity coefficient that is nearly 72% of the well-known piezoelectric (quartz) or 36% of boron nitride nanotubes.
Effects of drugs on 2',3'-dideoxy-2',3'-didehydrothymidine phosphorylation in vitro (1997)

Drugs commonly administered to patients infected with the human immunodeficiency virus (HIV) have been studied for their propensity to alter the intracellular phosphorylation of the anti-HIV nucleoside analog stavudine (2',3'-dideoxy-2',3'-didehydrothymidine; d4T) in peripheral blood mononuclear cells (PBMCs) and U937 cells in vitro. PBMCs isolated from the blood of healthy volunteers were stimulated by the mitogen phytohemagglutinin (10 microg/ml) for 72 h. Stimulated PBMCs (3 x 10(6) cells/plate) were then incubated with [3H]d4T (0.65 microCi; 3 microM) and either acyclovir, dapsone, ddC, ddI, fluconazole, foscarnet, ganciclovir, itraconazole, lobucavir, ranitidine, ribavirin, rifampin, sorivudine, sulfamethoxazole, trimethoprim, lamivudine (3TC), zidovudine, or thymidine (30 and 300 microM) for 24 h. Doxorubicin and drugs showing some evidence of inhibition were also studied at 0.3 and 3 microM. Cells were extracted overnight with 60% methanol prior to analysis by radiometric high-performance liquid chromatography. Additional data for nine of the drugs were obtained by incubation with [3H]d4T in U937 cells for 24 h. The effect of d4T (0.2 to 20 microM) on zidovudine (0.65 microCi; 0.018 microCi) phosphorylation was also studied. Zidovudine significantly reduced d4T total phosphates in PBMCs and U937 cells (in PBMCs to 33% [P < 0.001] and 17% [P < 0.001] of that in control cells at 3 and 30 microM, respectively). A small reduction in zidovudine phosphorylation was seen with d4T but only at d4T:zidovudine ratios of 100 and 1,000. Of the other compounds screened, only thymidine, ribavirin, and doxorubicin produced inhibition of d4T phosphorylation in both PBMCs and U937 cells. However, doxorubicin was cytotoxic at 3 microM. The decrease in d4T phosphorylation in the presence of ribavirin is consistent with previous findings with zidovudine. Although ddC significantly inhibited the phosphorylation of d4T in PBMCs, this was not seen in U937 cells, and it is probable that the findings in PBMCs are related to mitochondrial toxicity [based on 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide cytotoxicity assay]. The only drugs screened which may interfere with d4T phosphorylation at clinically relevant concentrations were zidovudine, ribavirin, and doxorubicin.
