Graph-Analytical Method of Determining Impedance in Electrical Transformers (2015)

This paper presents a graph-analytical method for determining the electrical impedance of alternate energy sources, especially small power transformers and current transformers in electric networks. Unlike conventional short-circuit and idle tests, according to proposed method, in this paper, transformer parameters are determined in a new way, which is based on measurement of voltages and currents on the active and reactive load (inductive or capacitive). The effectiveness of the proposed model was verified using an adapted simulation in the software package MATLAB Simulink. The simulation was performed for three types of ABB transformers with a 100% load. Simulation results were obtained for power transformers:<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:msub><mml:mrow><mml:mi>S</mml:mi></mml:mrow><mml:mrow><mml:mi>n</mml:mi><mml:mn>1</mml:mn></mml:mrow></mml:msub><mml:mn>=1 [</mml:mn><mml:mtext>MVA</mml:mtext><mml:mn>]</mml:mn></mml:math>,<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M2"><mml:msub><mml:mrow><mml:mi>S</mml:mi></mml:mrow><mml:mrow><mml:mi>n</mml:mi><mml:mn>2</mml:mn></mml:mrow></mml:msub><mml:mn>=2 [</mml:mn><mml:mtext>MVA</mml:mtext><mml:mn>]</mml:mn></mml:math>,<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M3"><mml:msub><mml:mrow><mml:mi>S</mml:mi></mml:mrow><mml:mrow><mml:mi>n</mml:mi><mml:mn>3</mml:mn></mml:mrow></mml:msub><mml:mn>=3.15 [</mml:mn><mml:mtext>MVA</mml:mtext><mml:mn>]</mml:mn></mml:math>.

For reactance results, deviations are up to 20% for all three tested transformers. For results of active resistance tolerances are up to 5% for all three tested transformers.

Organometallic Aqua Complexes, III. Olefin Aqua Complexes of Rhodium(I) (1995)

Abstract Dehalogenation of halide precursors [(olefin)RhCl] 2 [olefin = ethylene, 1,5‐cyclooctadiene (COD], norbornadiene (NBD), 2,3‐dimethylbutadiene (DMB)] in water gave the respective cis ‐diolefin aqua ions, characterized by NMR spectroscopy in solution. Attempted isolation of the tosylate salt [(COD)Rh‐(H 2 O) 2 ]OTs yielded crystals of (COD)Rh(H 2 O)(η 1 ‐OTs) characterized by X‐ray structural analysis. [(NBD]Rh(H 2 O) 2 ]SbF 6 in the presence of adventitious toluene decomposed into [(NBD])Rh(η 6 ‐toluene)]SbF 6 and [(NBD] 2 Rh]SbF 6 , both complexes were isolated and structurally characterized. Ethylene exchange in [(C 2 H 4 ) 2 Rh(H 2 O) 2 ] + is fast with k 2 of the order of 10 4 –10 5 s ‐1 · M ‐1 . The rate constant for water exchange in [CODRh(H 2 O) 2 ] + is estimated as 10 4 s ‐1 (ΔDL G ≈︁ 25 kJ/mol) at 173 K.

Über eine ungewöhnliche Cyclisationsreaktion bei der Umsetzung von (+)‐Epoxy‐α‐dihydrojonon mit Hydrazinhydrat (1970)

Abstract (+)‐Epoxy‐α‐dihydroionone ( 2 ) is formed completely stereospecifically from (+)‐α‐ionone ( 1 ). Under the conditions of the Wharton reaction this epoxide gives the expected isomeric allyl alcohols 4 and 5 and, surprisingly, the bicyclic allyl alcohol 3 . The structure and absolute configuration of the reaction products have been established. A common intermediate for the formation of compounds 3, 4 and 5 is probably the vinyl anion C.
Slow Dynamics of Water Molecules in Supercooled States (1996)

We perform long molecular dynamics simulations of liquid water in normal and supercooled states for times up to 50 ns. We observe the onset of a cage effect at 0.25 ps followed by diffusion at much longer time. The diffusion constant has a power-law temperature dependence. The long-time single-particle dynamics of supercooled water is dominated by a two-step process, beta and alpha relaxations, familiar in the mode-coupling theory of supercooled simple liquids. Over length scales comparable to the cage size alpha decay is characterized by a relaxation rate having a ${q}^{2}$ to $q$ crossover close to the kinetic glass transition temperature.
Taking time seriously: hidden Markov experts applied to financial engineering (2002)

Most traditional time series models are global models based on local time information: they assume that the state can be fully and locally (in time) characterized with a finite embedding space. Prediction then amounts to simple regression. Unfortunately, there are many situations in which simple regression is not sufficient to model the temporal structure in a time series. The authors introduce an architecture that they call hidden Markov experts. It is based on hidden Markov models used in speech recognition research. By introducing the concept of hidden states, hidden Markov experts model time dependency of time series explicitly as a first-order Markov model with transitions between these hidden states. Within each state, local models are applied to estimate the probability density, which can be linear or nonlinear depending on the situation. The paper first discusses the statistical framework and the learning algorithm of hidden Markov experts, then applies them to daily S&P500 data and to high frequency currency exchange rate data. The hidden Markov experts have better profit than the linear and nonlinear global models. The volatilities of the time series can be characterized by the hidden states.
PCA+HMM+SVM for EEG pattern classification (2003)

Electroencephalogram (EEG) pattern classification plays an important role in the domain of brain computer interface (BCI). Hidden Markov model (HMM) might be a useful tool in EEG pattern classification since EEG data is a multivariate time series data which contains noise and artifacts. In this paper we present methods for EEG pattern classification which jointly employ principal component analysis (PCA) and HMM. Along this line, two methods are introduced: (1) PCA+HMM; (2) PCA+HMM+SVM. Usefulness of principal component features and our hybrid method is confirmed through the classification of EEG that is recorded during the imagination of a left or right hand movement.

Position Modulation Code for Rewriting Write-Once Memories (2009)

A write-once memory (wom) is a storage medium formed by a number of ``write-once'' bit positions (wits), where each wit initially is in a `0' state and can be changed to a `1' state irreversibly. Examples of write-once memories include SLC flash memories and optical disks. This paper presents a low complexity coding scheme for rewriting such write-once memories, which is applicable to general problem configurations. The proposed scheme is called the \emph{position modulation code}, as it uses the positions of the zero symbols to encode some information. The proposed technique can achieve code rates higher than state-of-the-art practical solutions for some configurations. For instance, there is a position modulation code that can write 56 bits 10 times on 278 wits, achieving rate 2.01. In addition, the position modulation code is shown to achieve a rate at least half of the optimal rate.
Point of Care Ultrasound Diagnosis of Upper Gastrointestinal Bleeding (2017)

A 28-year-old male was brought to the emergency department by the Emergency medical services (EMS) after being found unconscious and unresponsive. Upon arrival, he was hypotensive, intubated with a Glasgow Coma Scale (GCS) 3T, without the signs of trauma or the evidence of bleeding. A focused assessment with sonography in trauma (FAST), point-of-care ultrasound (POCUS) was performed, obscuring part of the spleen from the distended stomach, which was filled with the heterogeneous contents, with the internal movement being identified. This was found to be blood after orogastric (OG) tube was placed for suction. The bedside endoscopy confirmed active variceal bleeding. This case illustrates the potential utility of the ultrasound in detecting the upper gastrointestinal bleeding.
Properties of GaN tunneling MIS light-emitting diodes (1978)

MIS structures on GaN consisting of Au-NaI-GaN or Au-Al2O3-GaN with insulator thickness &lt;100 Å have been fabricated with the aim of producing light-emitting diodes with emission in the uv and blue spectral region at low bias. I-V characteristics are consistent with a tunneling carrier transport mechanism, and light emission typically occurs for voltages 2–3 V. The spectral behavior of electroluminescence (EL) is in good agreement with photoluminescence (PL) data in the uv and blue spectral region. Suggestions for further work to improve radiant power output from such devices are presented.
Enthalpy (Δ<i>H</i>) and Entropy (Δ<i>S</i>) for π-Stacking Interactions in Near-Sandwich Configurations:  Relative Importance of Electrostatic, Dispersive, and Charge-Transfer Effects (2007)

Interactions between two aromatic rings with various substituents in a near-sandwich configuration have been quantitatively studied by using the triptycene derived molecular models. This model system allows a stacking arrangement of two arenes to assume a near-perfect face-to-face configuration in its ground state conformation. Comparing to our previous study of the parallel displaced configuration, repulsive interactions are predominant for most arenes currently studied. However, if one arene is strongly electron deficient (Ar2=pentafluorobenzoate), attractive interactions were observed regardless of the character of the other arene (Ar1). For stacking interactions between Me2NC6H4 and C6F5CO groups, a DeltaH of -1.84+/-0.2 kcal/mol and a DeltaS of -2.9+/-0.8 cal/(mol.K) were determined. The general trend in the attractive stacking interaction toward a pentafluorobenzoate is Me2NC6H4>Me3C6H2>Me2C6H3>MeC6H4>MeOC6H4>C6H5>O2NC6H4. The observed trend is consistent with a donor-acceptor relationship and the acceptor is a C6F5CO group.

Thermionic Energy Conversion and Metallic-Fluid Heat Pipes: High Power Densities from High-Temperature Material Interactions (1982)

Thermionic energy conversion (TEC) and metallic-fluid heat pipes (MFHP) offer important and unique advantages in terrestrial and space energy processing. They are also well suited to serve together synergistically. TEC and MFHPS operate through working-fluid vaporization, condensation cycles that accept great thermal power densities at high temperatures. TEC and MFHPs have apparently simple, isolated performance mechanisms that are somewhat similar. And they also have obviously difficult, complected material problems that again are somewhat similar. Intensive investigation reveals that aspects of their operating cycles and material problems tend to merge: ''In short, high-temperature material effects determine the level and lifetime of ... performance.'' Simplified equations verify the preceding statement for TEC and MFHPs. Material properties and interactions exert primary influences on operational effectiveness. And thermophysicochemical stabilities dictate operating temperatures which regulate the thermoemissive currents of TEC and the vaporization flow rates of MFHPs. Major high-temperature material problems of TEC and MFHPs have been solved. These solutions lead to productive, cost-effective applications of current TEC and MFHPs — and point to significant improvements with anticipated technological gains.
Phase I and Pharmacokinetic Study of the Cytotoxic Ether Lipid Ilmofosine Administered by Weekly Two-Hour Infusion in Patients with Advanced Solid Tumors (2004)

The dose-limiting toxicity of ilmofosine is gastrointestinal and the recommended dose for Phase II trials is 450 mg/m(2) as a 2-h weekly infusion. The relatively long half-life of ilmofosine and its active metabolite support the use of this intermittent schedule.
Alicyclobacillus pohliae sp. nov., a thermophilic, endospore-forming bacterium isolated from geothermal soil of the north-west slope of Mount Melbourne (Antarctica) (2008)

Gram-positive, rod-shaped, endospore-forming, thermophilic bacteria were isolated from a geothermal soil collected on the north-west slope of Mount Melbourne in Antarctica. They grew aerobically at 42-60 degrees C (optimum 55 degrees C) and at pH 4.5-7.5 (optimum pH 5.5). Phylogenetic analysis of 16S rRNA gene sequences showed that these isolates were related most closely to the type strain of Alicyclobacillus pomorum (91% similarity). Growth occurred in the presence of ferrous iron at micromolar concentrations and acid was produced from various sugars. Iso-branched fatty acids C(15:0) (45.56%) and C(17:0) (35.81%) were the most abundant cellular fatty acids. The DNA G+C content was 55.1 mol%. On the basis of phenotypic and phylogenetic characteristics, it is concluded that these strains represent a novel species of the genus Alicyclobacillus, for which the name Alicyclobacillus pohliae sp. nov. is proposed. The type strain is MP4(T) (=CIP 109385(T) =NCIMB 14276(T)).

From n-gram to skipgram to concgram (2006)

Uncovering the extent of word associations and how they are manifested has been an important area of study in corpus linguistics since the 1960s (Sinclair et al. 1970). This paper defines and describes a new way of categorising word association, the concgram , which constitutes all of the permutations of constituency and positional variation generated by the association of two or more words. Concgrams are identified without prior input from the user (other than to set the size of the span) employing a fully automated search that reveals all of the word association patterns that exist in a corpus. This study argues that concgrams represent more fully word associations in a corpus. Most concgrams seem to be non-contiguous, and show both constituency (AB, ACB) and positional (AB, BA) variations. Further studies of concgrams will help in the task of uncovering the full extent of the idiom principle (Sinclair 1987).
A new GaN based field effect Schottky barrier diode with a very low on-voltage operation (2004)

We first demonstrated a new structure of GaN Schottky diode, with dual Schottky structures. That is, a field effect Schottky barrier diode (FESBD) was fabricated. The purpose of this diode was to lower the on-state voltage and to maintain a high reverse breakdown voltage. This diode was fabricated using an AlGaN/GaN heterojunction and a selective area growth (SAG) technique. We obtained an on-state voltage below 0.1 V, using a vertical type FESBD and the breakdown voltage was over 400 V using a planar type FESBD.
Self-configuring Software-defined Overlay Bypass for Seamless Inter- and Intra-cloud Virtual Networking (2016)

Many techniques have been proposed to provide, transparently, the abstraction of a layer-2 virtual network environment within a provider, e.g. by leveraging Software-Defined Networking (SDN). However, cloud providers often constrain layer-2 communication across instances; furthermore, SDN integration and layer-2 messaging between distinct domains distributed across the Internet is not possible, hindering the ability for tenants to deploy their virtual networks across providers. In contrast, overlay networks provide a flexible foundation for inter-cloud virtual private networking (VPN), by tunneling virtual network traffic through private, authenticated end-to-end overlay links. However, overlays inherently incur network virtualization overheads, including header encapsulation and user/kernel boundary crossing. This paper proposes a novel system -- VIAS (VIrtualization Acceleration over SDN) -- that delivers the flexibility of overlays for inter-cloud virtual private networking, while transparently applying SDN techniques (available in existing OpenFlow hardware or software switches) to selectively bypass overlay tunneling and achieve near-native performance for TCP/UDP flows within a provider. Architecturally, VIAS is unique in how it integrates SDN and overlay controllers in a distributed fashion to coordinate the management of virtual network links and flows. The approach is self-organizing, whereby overlay nodes can detect that peer endpoints are in the same network and program bypass flows between OpenFlow switches. While generally applicable, VIAS in particular applies to nested VMs/containers across cloud providers, supporting seamless communication within and across providers. VIAS has been implemented as an extension to an existing virtual network overlay platform (IP-over-P2P, IPOP) by integrating OpenFlow controller functionality with distributed overlay controllers. We evaluate the performance of VIAS in realistic cloud environments using an implementation based on IPOP, the RYU SDN framework, Open vSwitch, and LXC containers across various cloud environment including Amazon, Google compute engine, and CloudLab.
Tissue Distribution of Loperamide and N-Desmethylloperamide Following a Fatal Overdose (2005)

We report a case involving a fatal intoxication with loperamide (Imodium). Loperamide is a synthetic opioid of the phenyl piperidine class used as an over-the-counter antidiarrheal. It exerts its effects through interaction with micro-opiate receptors in the intestine to reduce peristalsis. Loperamide lacks the typical euphoric opiate effects when administered at recommended doses. Both loperamide and its major metabolite, N-desmethylloperamide, were isolated by liquid-liquid extraction into n-butyl chloride from alkalinized samples. Extracts were analyzed by liquid chromatography-electrospray-mass spectrometry in selected-ion-monitoring mode. Rapid separation of the drug, metabolite, and internal standard (diphenoxylate) was achieved using a high-resolution C18 column with 1.8-microm particle diameter. The mobile phase consisted of 0.1% formic acid in deionized water (60%) and acetonitrile (40%) at a flow rate of 0.5 mL/min. Heart blood concentrations for loperamide and its metabolite were 1.2 mg/L and 3.3 mg/L, respectively. In contrast, reported peak plasma concentrations of loperamide after administration of recommended daily doses of 16 mg did not exceed 0.012 mg/L in controlled trials. Because the heart blood ethanol concentration was 0.08 g/dL, the medical examiner ruled that the cause of death was loperamide and ethanol intoxication, and the manner of death as undetermined.
Frictional Behavior of Textile Fabrics Part I: Sliding Phenomena of Fabrics on Metallic and Polymeric Solid Surfaces (1997)

This paper presents experimental results on the sliding of fabrics on metallic and polymeric solid surfaces, showing the influence of the compression load at the solid-fabric interface and the nature of the solid material, and the effect of sliding speed on the sliding friction coefficient. At the same time, a physical description of the sliding phenomenon is given. On the basis of these observations, a theoretical approach is developed to explain the sliding friction behavior of fabrics on solid surfaces. Part II will deal with the waving and stick-slip phenomena, which are evident in the sliding process under certain conditions.
