A systematic comparison of PCA-based statistical process monitoring methods for high-dimensional, time-dependent processes

High-dimensional and time-dependent data pose significant challenges to Statistical Process Monitoring (SPM). Most of the high-dimensional methodologies to cope with these challenges rely on some form of Principal Component Analysis (PCA) model, usually classified as non-adaptive and adaptive. Non-adaptive methods include the static PCA approach and Dynamic PCA for data with autocorrelation. Methods, such as Dynamic PCA with Decorrelated Residuals, extend Dynamic PCA to further reduce the effects of autocorrelation and cross-correlation on the monitoring statistics. Recursive PCA and Moving Window PCA, developed for non-stationary data, are adaptive. These fundamental methods will be systematically compared on high-dimensional, time-dependent processes (including the Tennessee Eastman benchmark process) to provide practitioners with guidelines for appropriate monitoring strategies and a sense of how they can be expected to perform. The selection of parameter values for the different methods is also discussed. Finally, the relevant challenges of modeling time-dependent data are discussed, and areas of possible further research are highlighted. This article is protected by copyright. All rights reserved.
Investigation of STATCOM Ability in Voltage Support

This paper presents the application of static synchronous compensator (STATCOM) to control of voltage at a multi-machine power system installed with STATCOM as cast study. STATCOM is installed in one bus to control of voltage in the proposed bus. An optimization technique is used to tune the proposed STATCOM controllers. Several time-domain simulation tests visibly show the validity of proposed methods in voltage control and also damping of power system oscillations.

MAPKK-Independent Activation of p38α Mediated by TAB1-Dependent Autophosphorylation of p38α

Phosphorylation of mitogen-activated protein kinases (MAPKs) on specific tyrosine and threonine sites by MAP kinase kinases (MAPKKs) is thought to be the sole activation mechanism. Here, we report an unexpected activation mechanism for p38α MAPK that does not involve the prototypic kinase cascade. Rather it depends on interaction of p38α with TAB1 [transforming growth factor-β–activated protein kinase 1 (TAK1)–binding protein 1] leading to autophosphorylation and activation of p38α. We detected formation of a TRAF6-TAB1-p38α complex and showed stimulus-specific TAB1-dependent and TAB1-independent p38α activation. These findings suggest that alternative activation pathways contribute to the biological responses of p38α to various stimuli.
Biological characterization of radiation exposure and dose estimates for inhaled uranium milling effluents. Annual progress report, April 1981-March 1982

The problems addressed are the protection of uranium mill workers from occupational exposure to uranium through routine bioassay programs and the assessment of accidental worker exposures. Comparisons of chemical properties and the biological behavior of refined uranium ore (yellowcake) are made to identify important properties that influence uranium distribution patterns among organs. These studies will facilitate calculations of organ doses for specific exposures and associated health risk estimates and will identify important bioassay procedures to improve evaluations of human exposures. A quantitative analytical method for yellowcake was developed based on the infrared absorption of ammonium diuranate and U/sub 3/O/sub 8/ mixtures in KBr. The method was applied to yellowcake samples obtained from six operating mills. The composition of yellowcake from the six mills ranged from nearly pure ammonium diuranate to nearly pure U/sub 3/O/sub 8/. The composition of yellowcake samples taken from lots from the same mill was only somewhat less variable. Because uranium mill workers might be exposed to yellowcake either by contamination of a wound or by inhalation, a study of retention and translocation of uranium after subcutaneous implantation in rats was done. The results showed that 49% of the implanted yellowcake cleared from the body with a more » half-time (T sub 1/2) in the body of 0.3 days, and the remainder was cleared with a T sub 1/2 of 11 to 30 days. Exposures of Beagle dogs by nose-only inhalation to aerosols of commercial yellowcake were completed. Biochemical indicators of kidney dysfunction that appeared in blood and urine 4 to 8 days after exposure to the more soluble yellowcake showed significant changes in dogs, but levels returned to normal by 16 days after exposure. No biochemical evidence of kidney dysfunction was observed in dogs exposed to the less soluble yellowcake form. 18 figures, 9 tables. « less

Change in the Chemical Composition of Chestnuts (Castanea crenata) from Different Periods

Compositional changes of the Korean chestnut (Castanea crenata) including Daebo, Tsukuba, Tanzawa and Okkwang were investigated in order to characterize them from different periods (immature, mature and storage period). Proximate compositions of mature cultivars were higher than that of the immature cultivars. Between minerals, K (263.0- 420.6 mg/100 g) and P (45.8-69.6 mg/100 g) of Tanzawa were highest, and they gradually increased during storage. Tsukuba, in mature period, showed the highest contents of total essential amino acids and glutamic acids as savory amino acids. Major fatty acids were palmitic acid and linolenic acid in four cultivars. In addition, linoleic acids, as ω-6 fatty acids, were increased during the storage period. Tanzawa, in the mature period, presented the highest levels of sucrose, however, tsukuba, in the storage period, showed relatively higher free sugar content than others. β-Carotene, as a provitamin A, of Tsukuba in the mature period was highly detected among them, and vitamin C of Tsukuba and Tanzawa was more plentiful than others.
A simple theory of the electron-phonon mass enhancement in transition metal compounds

The problem of calculating the electron-phonon mass enhancement factor, lambda , in transition metal compounds is discussed and a simple expression for lambda is presented. NbN and NbC are treated in detail, using the results of band structure calculation. The calculation, which estimates lambda from first principles without the use of adjustable parameters, gives good quantitative agreement with lambda obtained from measurements of the superconducting transition temperature, Tc. The physical interpretation of the calculation is that, in both the nitride and the carbide, the light atoms scatter electrons strongly at the Fermi energy due to a p resonance, and cause Tc to be higher than in pure Nb.

Bacterial deposition in porous media : Effects of cell-coating, substratum hydrophobicity, and electrolyte concentration

Deposition of seven bacterial strains on spherical glass and Teflon collectors was studied in vertical down-flow columns at an ionic strength (I) of 0.1 M. The various bacteria had either one of the following types of major cell−surface constituents: nonpolysac charide (NP), amphiphilic (AMPH), or anionic polysaccharide (AP) macromolecules. Deposition was analyzed in terms of the clean bed collision efficiency α0 (the probability of a cell to attach upon reaching a substratum free of cells) and a blocking factor B (the ratio of the area blocked by an attached cell to the geometric area of a cell). The value of α0 decreased from 1.0 to about 0.01 in the following order of cell−surface constituents/collector combina tions: NP/Teflon and AMPH/Teflon > NP/glass > AMPH/glass, AP/Teflon, and AP/glass. The value for B, at a Peclet number of 1 × 105, increased from about 3 to 18 in the order NP/low cell charge < NP or AMPH/high cell charge < AP/high cell charge. This indicates that cell−cell repulsion enhances .
Dissolution of biogenic silica: Roles of pH, salinity, pressure, electrical charging and reverse weathering

The recycling of biogenic silica (bSiO2) produced by diatoms is a vital process sustaining a significant fraction of primary production in the oceans. The efficiency with which bSiO2 dissolves controls the availability of nutrient silicon in the water column, and modulates the export of organic carbon to the deep sea. Environmental conditions during biomineralization affect the silicification and weathering resistance of diatom frustules, while ecosystem processes are determining factors for the recycling of bSiO2 in the water column. The dissolution rate of diatom frustules is a function of the physicochemical properties of both the silica and the aqueous medium. This thesis focuses on the biogeochemical processes, physicochemical variables (salinity, pH, and pressure) and material properties that affect the recycling efficiency of biogenic silica, in the water column, in marine sediments and along the land to ocean continuum. It provides an overview of the current knowledge on the subject, and presents novel findings based on laboratory and field experiments.
The fluorescence properties of crystalline anthracenes and their dependence on the crystal structures

The fluorescence properties of a number of crystalline anthracenes are described. It is found that in excimer-emitting crystals the energy of the emission is shifted by change in temperature much more strongly in infinite-stack structures than in structures based on pair-wise packing. A theoretical treatment is given of the general problem of the excimer emission from a crystal, and is applied to the anthracenes. This theory shows that the sensitivity to temperature for high temperatures is determined by the ratio of the frequencies of intra-pair vibrations in ground and excited states of the particular material. An interpretation of the difference in this ratio for stack and pair structures is given, and some predictions based on this interpretation are given and tested. It is confirmed that structures in which molecular overlap is small give rise to monomer emission. Es werden die Fluoreszenzeigenschaften einer Anzahl Anthrazenkristalle beschrieben. Es wurde gefunden, das in „excimer”-emittierenden Kristallen die Emissionsenergie durch Temperaturveranderung in unendlieh gestapelten Strukturen viel starker verschoben ist als in Strukturen, die auf der paarweisen Stapelung beruhen. Es wird eine theoretische Behandlung des allgemeinen Problems der Excimer-Emission von einem Kristall angegeben und auf Anthrazen angewendet. Diese Theorie zeigt, das die Temperaturempfindlichkeit fur hohe Temperaturen durch das Verhaltnis der Intra-Paar-Schwingungen im Grundzu-stand und den angeregten Zustanden des betreffenden Materials bestimmt wird. Es wird eine Interpretation des Unterschieds in diesem Verhaltnis fur Stapel- und Paar-Strnkturen gegeben und es werden einige Vorhersagen auf der Grundlage dieser Interpretation gemacht und gepruft. Es wird bestatigt, das Strukturen, in denen die Molekuluberlappung klein ist, Anlas zu monomerer Emission geben.
Observation of Fuel Cell Membrane Degradation by Ex Situ and In Situ Electron Paramagnetic Resonance

Aiming at the development of accelerated stability tests of perfluorinated and polyaromatic proton conducting fuel cell polymer membranes, free-radical degradation was initiated by exposure to . OH radicals generated from hydrogen peroxide. All investigations were performed by electron paramagnetic resonance on various monomer and polymer solutions as well as on bare and coated polymers. No signals indicating an . OH attack on Nafion ionomers were detected, in contrast to all polyaromatic membrane materials. Nevertheless, in situ spin trap measurements with Nafion membranes reveal strong signals which formally belong to trapped H atoms but are not related to degradation. Relative to the Faraday electrons from the electrochemical reaction, they appear on a parts per million level.
Synthesis of Poly(tartar amides) as Bio‐Inspired Antifreeze Additives

Multifunctional poly(tartar amides) have been synthesized and used as bio-inspired antifreeze additives. It is shown that these polymers strongly interfere with the crystallization process of water in comparison to commercially available commodity polymers. While the addition of the poly(tartar amides) results in minor freezing point depression, as is shown by differential scanning calorimetry, a strong change in the ice crystal morphology is evident. Wide-angle X-ray scattering and optical microscopy indicate that the hexagonal structure of undisturbed ice-crystals is oriented and partly deformed.
Conversion processes in anaerobic digestion

Six different conversion processes are identified in the degradation of particulate organic material (biopolymers) to methane. Hydrolysis of particulate material is followed by the degradation of the hydrolysis and intermediary products by five independent groups of microorganisms. Process and growth kinetic data for the six processes are reviewed. The kinetic data are applied to the design of an anaerobic digester for raw domestic sludge. Variations in loading rates primarily affect acetate decarboxylation and, thereby, may cause shifts in pH which, in turn, cause the digester to operate in the acidic regime.
Naturalised grapevines collected from arid regions in Northern Chile exhibit a high level of genetic diversity

Background and Aims Grapevine introduction into South America occurred after Spanish colonisation during the 16th century. In Chile, some vines were established in small villages and oases along the Atacama Desert. Considering that these plants have survived harsh environmental conditions, we explored and collected naturalised vines from 18°34′LS (close to the Peruvian border) to 31°53′LS, in order to understand their genetic nature and preserve this germplasm. Methods and Results Over 150 grapevine accessions were collected and characterised using 11 Simple Sequence Repeats (SSR) markers, to determine the genetic diversity and to propose a population structuring. SSR diversity was high, with observed heterozygosity (Ho = 0.87) greater than expected heterozygosity (He = 0.70). Three discrete genetic groups were identified, which did not show any association with geographical distribution. Groups 1 (G1) and G3 had a higher level of genetic diversity and also an important level of heterozygosity. Conclusions The gene pool of naturalised grapevines from the Atacama Desert had a significant genetic diversity and exhibited an important level of heterozygote excess. Clustering of this diversity suggested that this naturalised grapevine germplasm would represent a novel source of allelic variants. Significance of the Study Naturalised and admixed genotypes are potential sources of new alleles, and are a unique source of diversity for grapevine breeding cultivars and/or rootstocks better adapted to the prospect of climate change.
Tolerancia al ultrasecado y a la temperatura de almacenamiento en semillas de tres especies nativas del Noroeste Argentino

La conservacion de semillas ortodoxas en bancos de germoplama se basa en la disminucion de contenido de humedad (CH) de las semillas hasta un 3-5% y en el almacenamiento a bajas temperaturas (-20oC). Sin embargo, se ha propuesto que si las semillas toleran la desecacion hasta ultrasecado (CH<3%), la longevidad de las mismas podria aumentar y no seria necesario el almacenamiento a bajas temperaturas. El objetivo de este trabajo fue evaluar la respuesta al ultrasecado y a la temperatura de almacenamiento Cedrela balansae, Cercidium praecox y Prosopis nigra. Se determino el CH de las semillas frescas, se realizaron ensayos de germinacion con semillas frescas, ultrasecadas y ultrasecadas y almacenadas al menos durante 28 meses en diferentes temperaturas (-20, 5 y 25oC). Los porcentajes de germinacion fueron superiores al 74% en todos los casos, independientemente de la temperatura de almacenamiento. Estos resultados indican que las semillas de las tres especies estudiadas toleran el ultrasecado y pueden ser almacenadas a temperatura ambiente sin perder viabilidad. El ultrase- cado permitiria el ahorro e independencia de energia y constituye una alternativa especialmente en paises en los que hay interrupciones en el suministro de electricidad, ademas de contribuir al conocimiento de nuestras especies nativas.
Thermodynamics of Small Systems

It is shown in this paper that the differential equations of macroscopic thermodynamics can be generalized in such a way that they apply as well to small (i.e., nonmacroscopic) systems. Conventional thermodynamic relations then follow from the present treatment as a limiting case (large system). As with macroscopic thermodynamics, there are two main classes of applications: (1) as an aid in analyzing, classifying, and correlating equilibrium experimental data on ``small systems'' such as (non‐interacting) colloid particles, liquid droplets, crystallites, macromolecules, polymers, polyelectrolytes, nucleic acids, proteins, etc.; and (2) to verify, stimulate, and provide a framework for statistical mechanical analysis of models of finite (i.e., ``small'') systems. A well‐known experimental and theoretical example (in which there are sizable effects of chain length) is the helix‐coil transition in synthetic polypeptides and polynucleotides. Unlike macroscopic thermodynamics, thermodynamic functions are diffe.
Spin-torque-induced oscillation at zero bias field in a magnetoresistive nanopillar with a free layer with first- and second-order uniaxial anisotropy

Spin-torque-induced magnetization dynamics in a nanopillar having a perpendicularly magnetized free layer with first- and second-order uniaxial anisotropy and an in-plane magnetized reference layer is studied theoretically on the basis of the macrospin model. It is shown that in the presence of second-order uniaxial anisotropy, self-oscillation is induced even at zero bias magnetic field. Analytical expressions for the threshold current, condition of the second-order anisotropy constant required for oscillation, and current dependence of the oscillation frequency are obtained.

Preparation of Porous Polysulfone Membranes Using Ionic Liquids with Different Alkyl Chain as Additives

1-alky-3-methylimidazolium hexfluorophosphate ([n-Cnmim][PF6]) and 1-alky-3- methylimidazolium thiocyanate ([n-Cnmim]SCN) (n=4,8,16) were firstly introducing into the casting solution (PSF/NMP), porous polysulfone (PSF) membranes were successfully prepared by the wet-phase-inversion. The scanning electron microscope was utilized to visualize the cross-sections of the membranes, in order to study the influence of ionic liquids with different alkyl chain on the porous structures. The results indicate that the PSF membranes have different structures and separation properties due to ionic liquids with different alky chain. For ionic liquids with the short alkyl chain, the prepared membranes have the porous structure on cross-sections, but no or weak separation properties. However, for ionic liquids with the long alkyl chain, the prepared membranes have both porous structure and good separation properties. According to the structure of a hydrophobic straight-long alkyl and a hydrophilic limidazolium ring, the ionic liquid with long alkyl chain is considered as a surfactant, it can change not only the interface properties between the casting solution and coagulation bath, but also induce the space structures of the polymer chains.
Effect of the Preparation Method on the Structural and Catalytic Properties of MnOx-CeO2 Manganese Cerium Mixed Oxides

MnOx-CeO2 catalysts (molar ratio Mn/Ce = 1) were prepared using two methods: co-precipitation and citrate methods. The prepared solids were calcined at 500°C, and characterized by XRD, nitrogen adsorption-desorption technique and SEM morphological, they were, then, tested in the toluene combustion reaction. The catalytic performances of the prepared solids were evaluated in the temperature range 150-400° C. The XRD analysis of the two solids showed that the only crystalline phase detected is cerium oxide. BET surface area measurements showed that the incorporation of manganese led to an increase in the specific surface area of ceria, the solid prepared by the co-precipitation method led to the highest specific surface area (156 m²/g). The solids showed good performances in the toluene combustion reaction that depend strongly on the preparation method. The best catalytic activity was obtained for the catalyst prepared by the citrate method achieving a complete conversion of toluene at 250 ° C.
