MENSURAÇÃO DO DESEMPENHO ESTRATÉGICO NA LÓGICA DO MODELO STROBER: UMA ANÁLISE NO SETOR DE REVENDA AUTOMOTIVA (2007)

A velocidade e intensidade das grandes transformações de natureza tecnológicas, culturais, sociais, econômicas e organizacionais ocorridas nos últimos, anos têm influenciado a natureza da estratégia adotada nas organizações. O trabalho apresenta os resultados de uma pesquisa realizada para mensurar o modelo de estrutura – conduta – desempenho mediante verificação empírica. O contexto escolhido para aplicação do modelo é o setor de revenda automotivo por apresentar características competitivas adequadas. Para tanto, utilizou-se como base o modelo STROBER, proposto por Tan e Litschert (1994), que é uma ampliação do modelo Strategic Orientation of Business Enterprises (STROBE), proposto pelo professor Venkatraman (1989). O modelo estrutural proposto compreendeu análise do ambiente competitivo externo, a natureza da estratégia e o desempenho alcançado. Foram confirmadas cinco de um total de doze hipóteses do modelo, sendo que quatro hipóteses não foram confirmadas, possivelmente em função do tamanho da amostra. Três hipóteses apresentaram uma relação contrária ao modelo orientador da pesquisa. O modelo testado mostrou-se satisfatório, porém com índice de ajuste marginalmente aceitável, o que motivou a busca por um modelo alternativo que contemplasse de maneira mais adequada os dados do estudo.
Graphical user languages for querying information: where to look for criteria? (2003)

The different parameters of a graphical user language, concerning kinds of representation and kinds of operations on these representations, are outlined. These parameters are related to the characteristics of tasks that they more or less support. Special aspects of a graphical query language have been derived from the psychological findings. The conceptual framework of R. Jackendoff (1983) is used to model user concepts in graphical query languages and to translate these concepts to relational database semantics.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Understand the Fundamental of Passive Video Filters (1996)

Our experience with 63 patients who had popliteal artery injuries sustained in civilian accidents is reported. Blunt injuries occurred in 53 patients and 49 had associated skeletal injuries. Eighteen patients suffered knee dislocation; six of these patients had associated fractures. Fractures of the upper third of the tibia occurred in 21 patients. Five patients had irreversible ischemia and required primary amputation. Thirteen amputations were required in 58 patients in whom arterial repair was performed, for an amputation rate of 22%. There were no amputations in 19 patients treated less than 6 hours after injury was sustained. Four deaths occurred. Fasciotomy was performed in 20 patients. Skeletal injuries were usually treated with external fixation.
Assessment of physicochemical and microbiological quality of UHT whole milk and proteolysis determination during storage (2013)

The aim of this work was aimed to evaluate physicochemical and microbiological quality of UHT whole milk, market in Londrina-PR, Brazil, as well as estimate gelation and proteolysis during storage period of 150 days at room temperature. Physicochemical analyses included determination of fat content; titratable acidity; ethanol stability; total solids; solids-not-fat; pH, density and freezing point. For proteolysis estimative, total nitrogen, non-casein nitrogen and non-protein nitrogen were quantified. Gelation estimation was carried out as well as mesophilic aerobes enumeration. Results obtained in this work demonstrate increase of gelation and proteolysis during storage and samples in disagreement with physicochemical and microbiological standards. The problems found in UHT milk quality standardization associated with increasing proteolysis and gelation during storage could lead to product rejection by the consumer.
A taxonomy for texture description and identification. (1989)

A central issue in computer vision is the problem of signal to symbol transformation. However, this problem has received very little attention in the case of texture, which is an important visual cue. This dissertation presents a solution to the signal to symbol transformation problem for texture. The symbolic description scheme consists of a novel taxonomy for textures, and is based on appropriate mathematical models for different kinds of textures. The taxonomy classifies textures into the broad classes of disordered, strongly ordered, weakly ordered and compositional. Disordered textures are described by statistical measures, strongly ordered textures by the placement of primitives, and weakly ordered textures by an orientation field. Compositional textures are created from these three classes of textures by using certain rules of composition. The unifying theme of this dissertation is to provide st and ardized symbolic descriptions that serve as a descriptive vocabulary for textures. In order to describe weakly ordered textures symbolically, we first derive an orientation field. This is accomplished through a new algorithm, based on the gradient of Gaussian. This algorithm is optimal in estimating local orientation. It is also simpler and has better signal to noise ratio than previous approaches. The symbolic description of orientation fields is accomplished by using the geometric theory of differential equations and is based on the visual appearance of phase portraits. We employ a non-linear least squares technique to determine the phase portraits that best describe local regions of the orientation field. Disordered textures are described through fractal-based techniques. We suggest the use of Frieze groups and wallpaper groups for the symbolic description of strongly ordered textures. We present a compositional scheme for texture that allows one to create compositions of the basic textures given above. This scheme forms a useful representation for an arbitrary texture. The algorithms developed in this dissertation have been applied to a wide variety of textured images arising in semiconductor wafer inspection, flow visualization and lumber processing. The taxonomy for texture can serve as a scheme for the identification and description of surface flaws and defects occurring in a wide range of practical applications.
Embedded nanotransducer for ultrahigh-frequency SAW utilizing AlN/diamond layered structure (2017)

In this work, we report the development and realization of ultrahigh-frequency, high-performance nano interdigital transducers (n-IDTs) for generation of surface acoustic wave (SAW) on aluminum nitride (AlN)/diamond/Si substrates, where the metal fingers are embedded in the AlN film. The well-defined n-IDTs' resolution down to 200 nm were obtained using electron beam lithography, inductively coupled plasma (ICP) etching and lift-off processing. The fabricated SAW resonators exhibit response at a ultrahigh-frequency range, as high as 9.94 GHz, with stronger intensities of S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> peaks compared with normal transducer devices. The good high-frequency characteristics of the embedded n-IDTs and compatibility with existing fabrication technologies pave the way for the realization of advanced sensors and monolithic integrated MMICs on AlN/diamond/Si substrates for the high frequency and high power applications.
Imagery and Adjudication in the Criminal Law: The Relationship between Images of Criminal Defendants and Ideologies of Criminal Law in Southern Antebellum and Modern Appellate Decisions (1995)

Criminal law opinions often project a distinct image of the accused. Sometimes, she is cast in a sympathetic light and may appear vulnerable or impressionable: a single mother, whose husband has died, struggling to raise her two, loving children; an impoverished, nineteen-year-old African-American with a fifth-grade education, "mentally dull and 'slow to learn;'" or a defenseless "obedient servant," protecting himself from an "adversary armed with a deadly weapon." On other occasions, the defendant may appear threatening, savage or even diabolical: a cold-blooded recidivist that escapes from a prison workcrew, brutally stabs, rapes and murders a woman, and returns for a hot lunch with his fellow inmates; a six-foot-tall "black male" rapist wearing a black jacket with "Big Ben" printed on the back; a "brute creation" or a ran-away, "lurking in swamps, woods, and other obscure places, killing hogs, and committing other injuries to ... inhabitants."
Introducing three dimensions (2008)

Through making models from recycled materials children develop understanding and skills in several areas.
Expanding the Eukaryote's Cast of Chaperones (1996)

In order for proteins to function normally, they must fold into the correct three-dimensional shapes, a task they accomplish with the aid of special proteins called “chaperones.” Three papers in this issue ( pp.1713 , 1715 , and 1718 ) are now making it clear that, at least in higher organisms, protein folding is far more complex than researchers had suspected. It seems to involve a whole retinue of chaperone proteins, including certain members of the immunophilin family—among the first evidence of what the normal function might be for these proteins, which are best known as the targets of immunosuppressive drugs.
Effect of purine and pyrimidine limitations on RNA synthesis in Bacillus subtilis (1984)

The effects of varying the intracellular levels of GTP or UTP on the rate of RNA synthesis in Bacillus subtilis were studied. The levels of these nucleotides were manipulated by pyrimidine limitation in a pyr auxotroph, by purine limitation in a pur auxotroph, or by the addition of decoyinine , which specifically inhibits GMP synthesis. Decreased levels of UTP and GTP were accompanied by dramatically decreased synthesis and accumulation of stable RNAs (tRNA and rRNA), but mRNA synthesis was less affected. However, sporulation was initiated only when the intracellular level of GTP decreased.
<sup>13</sup>C NMR Spectroscopy for the Differentiation of Enantiomers Using Chiral Solvating Agents (2013)

The utility of (13)C NMR spectroscopy for the differentiation of enantiomers using chiral solvating agents (CSA) is stated. Three examples involving the enantiodifferentiation of a drug, a metabolite and a reactant in aqueous and organic solutions have been chosen to show it. The intrinsic high dispersion of (13)C nucleus, as well as the singlet nature of the signals in standard experiments makes (13)C NMR experiments a powerful alternative or complement to (1)H NMR experiments; specially, when studying pure compounds with complex proton spectra or mixtures of compounds, as in chiral metabonomics, where severe overlapping exists in proton spectrum. To evaluate and compare the quality of the enantioresolution of a NMR signal we introduce the enantiodifferentiation quotient, E, that considers the complexity of (1)H multiplets (and in general the width) of the original signal. It has been observed that the error in the measurement of the enantiomeric molar ratio can be related to the E value. The sensitivity and experimental time of a wide range of chiral analyte concentrations were also assessed.
纺织配色专家系统—Smart Match (1996)

一、引言 配色处方计算质量的好坏主要取决于描述反射、吸收和散射之间关系的算法的有效性。大多数配色计算都采用库贝尔卡—芒克(Kubel-ka-Munk)理论和Beer定律。但是,实际使用的染料、染色工艺以及纺织品的性能却只能部分满足这些理论所要求的边界条件。因此,一次配色的小误差成功率通常只有30—80％。为了有效地提高一次配色的质量,Datacolor Inter-national公司推出了一种新的计算方法,该方法命名为“Smart Match”。这种软件除了传统配色计算之外,还包括能在第一次染色前就消除因实际情况与理论条件不一致而引起的偏差的校正算法。有了这种校正算法,只需有一组简
Modular deep trench isolation scheme for 38 GHz self-aligned double polysilicon bipolar devices (2002)

A modulator CMOS-compatible isolation scheme which is based on a deep trench technology combined with LOCOS is presented. In contrast to already established schemes, trench formation is postponed until after the LOCOS process. Thus thermal cycling is minimized. The high-performance potential of this isolation technology is demonstrated via fabrication of self-aligned double polysilicon transistors featuring a maximum cutoff frequency of 38 GHz.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The PSO family: deduction, stochastic analysis and comparison (2009)

The PSO algorithm can be physically interpreted as a stochastic damped mass-spring system: the so-called PSO continuous model. Furthermore, PSO corresponds to a particular discretization of the PSO continuous model. In this paper, we introduce a delayed version of the PSO continuous model, where the center of attraction might be delayed with respect to the particle trajectories. Based on this mechanical analogy, we derive a family of PSO versions. For each member of this family, we deduce the first and second order stability regions and the corresponding spectral radius. As expected, the PSO-family algorithms approach the PSO continuous model (damped-mass-spring system) as the size of the time step goes to zero. All the family members are linearly isomorphic when they are derived using the same delay parameter. If the delay parameter is different, the algorithms have corresponding stability regions of any order, but they differ in their respective force terms. All the PSO versions perform fairly well in a very broad area of the parameter space (inertia weight and local and global accelerations) that is close to the border of the second order stability regions and also to the median lines of the first order stability regions where no temporal correlation between trajectories exists. In addition, these regions are fairly similar for different benchmark functions. When the number of parameters of the cost function increases, these regions move towards higher inertia weight values (w=1) and lower total mean accelerations where the temporal covariance between trajectories is positive. Finally, the comparison between different PSO versions results in the conclusion that the centered version (CC-PSO) and PSO have the best convergence rates. Conversely, the centered-progressive version (CP-PSO) has the greatest exploratory capabilities. These features have to do with the way these algorithms update the velocities and positions of particles in the swarm. Knowledge of their respective dynamics can be used to propose a family of simple and stable algorithms, including hybrid versions.
Prognostic significance of beta-myosin heavy chain mutations is reflective of their hypertrophic expressivity in patients with hypertrophic cardiomyopathy. (1997)

Hypertrophic cardiomyopathy patients with the malignant Arg719Trp mutation have more extensive hypertrophy than those with the benign Leu606Val mutation. This findings suggests that the prognostic significance of beta-MyHC mutations is reflective of their hypertrophic expressivity.
A GaN transistor based 90W AC/DC adapter with a buck-PFC stage and an isolated Quasi-switched-capacitor DC/DC stage (2014)

This paper presents a GaN Transistor based 90W ac/dc adapter with a Buck-PFC stage and an isolated Quasi-Switched-Capacitor (QSC) dc/dc stage. In the dc/dc stage, two different QSC converters are proposed. Compared to Flyback and LLC resonant converters, the QSC converters feature: 1) reduced voltage stress on the primary-side switches to 2/3 of the input voltage; 2) reduced voltage stress on the transformer to 1/3 of the input voltage and a lower transformer turns ratio; 3) a wide range for soft-switching operation and high efficiency; 4) a simple control strategy. The operation principles and simulation results are presented. A 90 W, 85 V/19 V, 1 MHz QSC resonant converter is built, using 100 V EPC eGaN FETs for all switches. This prototype achieves: 1) a high power density of 10.5 W/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> ; 2) wide-range soft switching and a peak efficiency of 92.8% at 900 kHz in preliminary test results. A Buck-PFC evaluation module from TI is tested with a GaN HEMT and a SiC Schottky diode. The peak efficiency reached 97.1%, and the experimental results are compared with those from the Si based version.
Biomimetic synthesis of brevicolline from tryptophan, acetaldehyde, and N-methyl-Δ<sup>1</sup>-pyrrolinium acetate (1979)

1-Methyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid, produced in situ from tryptophan and acetaldehyde, was oxidatively decarboxylated with sodium hypochlorite affording a dihydro-β-carboline which on condensation with N-methyl-Δ1-pyrrolinium acetate and subsequent aerial oxidation afforded brevicolline.
Tumor-stroma interactions and stromal cell density regulate hepatocyte growth factor protein levels: a role for transforming growth factor- beta activation (1995)

Hepatocyte growth factor/scatter factor (HGF/SF), a fibroblast-derived mediator of epithelial and endothelial growth and motility, is regulated by factors present in media conditioned by breast tumor cell lines. Both inhibitory and stimulatory effects were observed dependent on culture conditions. The present work shows that breast tumor cell conditioned medium contains a latent HGF/SF inhibitory activity, which can be activated by a variety of treatments known to activate latent transforming growth factor-beta. Using blocking antibodies and other criteria, we show that transforming growth factor-beta present in epithelial cell conditioned medium is primarily responsible for mediating the down-regulation of fibroblast HGF/SF. Epithelial cell conditioned medium also contains a trypsin-sensitive and heat-stable stimulatory activity. Stromal cell density but not proliferation rate markedly alters HGF/SF expression. These results indicate that the expression of at least one epithelial morphogen, HGF/SF, is interdependently regulated by mesenchymal condensation and by factors released by neighboring epithelial and carcinoma cells.
Building energy and comfort management through occupant behaviour pattern detection based on a large-scale environmental sensor network (2011)

Detection of occupant presence has been used extensively in built environments for applications such as demand-controlled ventilation and security. However, the ability to discern the actual number of people in a room is beyond the scope of most current sensing techniques. To address this issue, a complex environmental sensor network is deployed in the Robert L. Preger Intelligent Workplace (IW) at Carnegie Mellon University. The results indicate that there are significant correlations between measured environmental conditions and occupancy status. It is shown that an average of 83% accuracy on the occupancy number detection was achieved by Gaussian Mixture Model based Hidden Markov Models during testing periods. To illustrate the consequent energy impact based on the occupant behaviour detection (i.e. number and duration of occupancy) in the space, an EnergyPlus model of the IW with an assumed standard variable air volume (VAV) system is created. Simulations are conducted to compare the energy consumption consequences between a prescribed occupancy schedule according to the ASHRAE 90.1 base case with the predicted occupancy behaviour. The results show that energy saving of 18.5% can be achieved in the IW while maintaining indoor thermal comfort.

Nickel-Based Alloys in Carbonaceous Gases (2000)

High-temperature corrosion in carbonaceous gases can occur by carburization (i.e., internal carbide formation at C activities [aC] &lt; 1 and at temperatures &gt; 800°C) or by metal dusting, a disintegration of alloys into graphite and metal particles observed at aC &gt; 1 and in a lower temperature range. In both cases, C entry and diffusion in the metal matrix is a decisive step, and in comparison to high-alloy steels, the C ingress in Ni-based alloys is retarded by the decrease of C solubility and diffusivity with increasing Ni content. Therefore, Ni-based alloys are recommended for applications in carbonaceous gases (e.g., for the steam-cracking of hydrocarbons). Since operating temperatures &gt; 1,100°C are desired in ethylene (C2H4) production, where chromium oxide (Cr2O3) is no more stable, the alloys must contain Si and/or Al to form a protective scale. At temperatures ≤ 650°C, high Ni-based alloys with ≥ 25% Cr and some Al proved to be very resistant to metal-dusting attack by the carbonaceous syngas (CO-H2) environment. Such alloys showed no attack in laboratory and pilot plant exposures for up to 10,000 h, whereas all high-alloy steels were susceptible.
Gas Permeation and Diffusion Characteristics of MFI-Type Zeolite Membranes at High Temperatures (2009)

MFI-type zeolite membranes were prepared by the template-free secondary growth method followed by onstream counter-diffusion or one-side chemical vapor deposition (CVD) modification to eliminate intercrystalline pores. Gas permeation and separation experiments were conducted on unmodified and modified membranes at 25−500 °C. For unmodified MFI-type zeolite membranes, single-gas permeation of H2, He, CO, and CO2 exhibits characteristics of Knudsen diffusion up to 500 °C, and adsorption of CO2 on MFI-type zeolite has a strong effect on ternary gas separation (H2, CO, and CO2) below 300 °C. Counter-diffusion CVD modification is effective in sealing the intercrystalline gaps resulting in defect-free MFI-type zeolite membranes. Permeation of nonadsorbing gases (He, H2, and CO) through counter-diffusion CVD-modified zeolite membranes also exhibits Knudsen diffusion characteristics with very small activation energies for diffusion (0.1−3 kJ mol−1), with gas permeance (diffusivity) decreasing with increasing molecular weight. For one-side CVD-modified MFI-type zeolite membranes, gas permeance (diffusivity) decreases and activation energy for diffusion increases with increasing molecular size because of the formation of an amorphous microporous silica layer. High-temperature gas permeation data on defect-free MFI-type zeolite membranes confirm the translational gas diffusion model for zeolites.
Inadvertent Metal Loading of Critically Ill Patients with Acute Renal Failure by Human Albumin Solution Infusion Therapy (1988)

Recent reports on the metal contamination of human albumin solutions (HAS) have raised concern about possible medical implications. Large amounts of HAS are infused to premature babies with respiratory distress syndrome, patients with plasmapheresis treatment or acute renal failure. For assessment of the risk of metal loading in patients with acute renal failure, commercially available HAS were analyzed for aluminium, nickel, chromium, manganese, cobalt, zinc, copper, cadmium, lead, and mercury. A considerable contamination of HAS was found for Al, Ni, Cr, Mn, and in part for Co. Additionally, the influence of 3 weeks of daily HAS infusion on metal blood levels was studied in 8 critically ill patients with acute renal failure, protein catabolism, ventilator therapy and hemodialysis treatment. Since most metals are primarily eliminated with the urine, these patients seemed to be at high risk for metal loading. In all patients, a considerable increase in the blood concentrations of Al, Ni, Cr, and in some patients of Mn and Co was found. In addition, the daily dose of Al, Ni, Cr, Mn, and Co by HAS was calculated for the 21st day after start of HAS infusion. In most patients, the dose of Al, Ni, and Cr considerably exceeded (up to a factor of 10) the average daily metal dose absorbed from the diet by healthy subjects. The increase in Mn and Co blood levels, despite a low dose of Mn and Co with the daily HAS infusion, was most likely caused by depletion of Mn and Co tissue stores due to the catabolic state of the patients. The contamination of HAS probably originated from the use of aluminum hydroxide and from contact of plasma with stainless steel surfaces during the Cohn fractionation process. The high extent of contamination of HAS with Al, Ni and Cr cannot be accepted since it is already technically feasible to produce HAS with metal concentrations comparable to the normal serum level range.
