Multidisciplinary Design Optimization Procedure for Improved Design of a Cooled Gas Turbine Blade

A multidisciplinary optimization procedure for gas turbine blade design has been developed and demonstrated on a generic 3-D blade. The blade is cooled both internally and externally (film cooling). Aerodynamic and heat transfer design criteria are integrated along with various constraints on the blade geometry. The blade is divided into numerous spanwise sections and each section is represented by a Bezier-Bernstein polynomial. A comprehensive solver for 3-D Navier-Stokes equations is used for the viscous flow calculations. The finite element method is used to obtain the blade interior temperatures. The average blade temperature and maximum blade temperature at each spanwise section are minimized, with aerodynamic and geometric constraints on the blade geometry. The constrained multiobjective optimization problem is solved using the Kreisselmeier-Steinhauser function approach. The results for a generic turbine blade design problem show significant improvements after optimization.
Multipole moments and Maxwell's equations

Maxwell's equations provide the basis for explaining many electromagnetic phenomena, both in vacuum and in matter. While some of these effects may be described within the electric dipole approximation D= in 0E+P and H= mu -10 B, there are others which require the inclusion of higher multipole terms in the fields D and H. Various practices for doing this have been adopted in the past, such as the use of traceless quadrupole and higher moments, and the neglect of certain moments. Some of these practices are shown to lead to Maxwell equations which are not translationally invariant, in that they depend on the choice of origin to which the multiple moments are referred, even though they may also yield expressions for observables which do not possess this defect. It is also shown how to obtain general multipolar forms for D and H which ensure origin-independent Maxwell equations.
A review on hypothalamo-pituitary- adrenal axis

The effector hormones of the hypothalamic-pituitary-adrenal axis neuroendocrine system are the glucocorticoid hormones cortisol and corticosterone.The level of corticosterone, a systemic intercellular signal, changes dynamically with environmental and psychological stressors and predictably varies with time of day. A wide range of physiological and mental health issues are linked to irregularities in the typical HPA axis activity profiles. Despite several investigations that have uncovered molecular, cellular, and systems-level glucocorticoid actions to date, more glucocorticoid actions, and connections with clinical state, need to be discovered. Hypothalamic-pituitary-adrenal (HPA) axis feedback regulation may be compromised due to reduced mineralocorticoid receptor (MR)-mediated feedback in the brain. Medicinal herbs and their compounds have been shown to have a preventative impact against depression through a variety of ways. Medicinal plants can provide fresh ideas for antidepressant medication research.
Goodness of Fit Tests for Spectral Distributions

Abstract : The spectral distribution function of a stationary stochastic process standardized by dividing by the variance of the process is a linear function of the autocorrelations. The integral of the sample standardized spectral density (periodogram) is a similar linear function of the autocorrelations. As the sample size increases, the difference of these two functions multiplied by the square root of the sample size converges is weakly to a Gaussian stochastic process with a continuous time parameter. A monotonic transformation of this parameter yields a Brownian bridge plus an independent radom term. The distributions of functionals of this process are the limiting distributions of goodness of fit criteria that are used for testing hypotheses about the process autocorrelations. An application is to tests of independence (flat spectrum). The characteristic function of the Cramer-von Miese statistic is obtained; inequalities for the Kolmogorow-Smirnov criterion are given. Confidence regions for unspecified process distributions are found.
Screening key genes related to neuropathic pain-induced depression through an integrative bioinformatics analysis

Background Neuropathic pain (NP) is often accompanied by sleep disorders, anxiety, depression and other complications, and the pathogenesis is still unclear. Some drugs can relieve patients’ pain, but the overall effect is not good. We screened for the key genes related to NP-induced depression based on bioinformatics. Methods The dataset of GSE92718 was obtained from the Gene Expression Omnibus database, data mining was conducted based on R language, the genes modules were screened by weighted correlation network analysis, Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis were performed, a protein-protein interaction (PPI) network was constructed in the STRING database, and hub genes were screened according to degree value. Results Seven modules were obtained and built to identify the relationships between the NP-induced depression and the modules, weighted gene co-expression network analysis (WGCNA) was used to identify gene modules closely related to the experimental group. The GO annotations of depression-related genes mainly enriched in protein polyubiquitination, regulation of chromosome organization, mitochondrial matrix, mitochondrial protein-containing complex, etc. KEGG enrichment analysis results were: Alzheimer’s disease, Huntington’s disease, ribosome, thermogenesis, prion disease, non-alcoholic fatty liver disease, diabetic cardiomyopathy, oxidative phosphorylation, retrograde endocannabinoid signaling, 2-oxocarboxylic acid metabolism. PPI network analysis showed that Polr2f, Rps13, Mrpl2, Mrpl40, Mrpl34, and Ndufs8 were more highly expressed in NP-induced depression. Functional analysis of key genes showed that these genes were related to mitochondrial translation termination, respiratory chain complex I, mitochondrial, mRNA Splicing (minor pathway), and of rRNA processing in the nucleolus and cytosol (major pathway). Conclusions The key genes of depression induced by NP are Polr2f, Rps13, Mrpl2, Mrpl40, Mrpl34, and Ndufs8.
Efficient calibration of the Hull White model

In this paper we study the calibration of the Hull White interest rate model for the pricing of Bermudan swaptions and Bermudan bond options. A common modelling approach for the calibration of the Hull White model is to choose the model parameters such that market prices of corresponding European derivatives are replicated by the model. This requires that a multidimensional non‐linear optimization problem has to be solved. The focus of this paper lies in the efficient formulation and numerical solution of this optimization problem. We investigate the numerical properties of the iterative solution of the optimization problem by means of a Gauss Newton and an Adjoint Broyden quasi‐Newton method. Required derivatives of the objective function are evaluated by techniques of Automatic Differentiation. The algorithms are benchmarked to Minpack's general purpose solver HYBRD. Numerical results for the calibration of long‐term Bermudan swaptions are reported. Copyright © 2011 John Wiley & Sons, Ltd.
Numerical Method for Calculation of Power Conversion Efficiency and Colorimetrics of Rectangular Luminescent Solar Concentrators

Similar to conventional photovoltaics, the path toward higher efficiencies for luminescent solar concentrators (LSCs) shows increased interest in tandem structures. Herein, a numerical calculation that allows for much faster estimates of fundamental LSC performance indicators (power conversion efficiency, average visible transmission, and color‐rendering index) compared to ray trace simulations is proposed. Both double and triple structures are assessed, taking into account concentrations, absorption and emission spectra, and quantum yield as luminophore inputs for rectangular LSCs of any size. The waveguide material is modeled using an absorption spectrum and a refractive index. Interactions between the first, second, and/or third LSCs are incorporated into the algorithm. A comparison with ray trace results shows good correspondence. Supplementary Excel files are available with detailed calculations for future research or industry applications.
A Multi Stub Polygon Shaped Textile Antenna for Deformation Performance Using Aperiodic DGS

A compact fully flexible antenna with 1.22 as dielectric constant with 0.016 loss tangent is designed for wearable biomedical applications. It has dimensions of 40.5 x 23 x 0.97 mm3. The polygon-shaped patch is modified to achieve ultra-wideband frequencies using partial ground as 16.5mm and a periodic vertical slot of 13x2 mm2 structure in defected ground structure to enhance the wide bandwidth of 2.6-11.1 GHz. Using a transmission line equation and a microstrip line feeding method, the resulting antenna operates at a biomedical frequency in open space and on the body-worn case with multi band i.e. 3.1 and 5GHz. The deformation process works well for the proposed antenna without affecting its actual bandwidth with 20 to 60 mm radii. Additionally, the proposed antenna operates at 5GHz for Wi-Fi with 3.67dBi gain, -35.1dB as S11 which is suitable for commercial applications. CST Microwave Studio was used to simulate the antenna and fabricate it for testing.
Molecular gas in elliptical galaxies

Observations of 24 early-type galaxies, mostly far-infrared (FIR)-bright ellipticals, in the 12 CO(2-1) emission line resulted in 10 detections including eight out of the 20 elliptical. Eight of these galaxies have not previously been detected. A search of the literature reveals a total of 17 elliptical galaxies, including our eight detections, with observed molecular gas, as well as 27 upper limits. Thus, our study almost doubles the number of elliptical galaxies detected in CO emission.
Nonlinear and non-Gaussian ocean noise

Bispectral analysis is a statistical tool for detecting and identifying a nonlinear stochastic signal generating mechanism from data containing its output. Bispectral analysis can also be employed to investigate whether the observed data record is consistent with the hypothesis that the underlying stochastic process has Gaussian distribution. From estimates of bispectra of several records of ambient acoustic ocean noise, a newly developed statistical method for testing whether the noise had a Gaussian distribution, and whether it contains evidence of nonlinearity in the underlying mechanisms generating the observed noise is applied. Seven acoustic records from three environments are examined: the Atlantic south of Bermuda, the northeast Pacific, and the Indian Ocean. The collection of time series represents both ambient acoustic noise (no local shipping) and noise dominated by local shipping. The three ambient records appeared to be both linear and Gaussian processes when examined over a period on the ord.
Biomedical Applications and Toxicological Aspects of Zinc Oxide Nanoparticles: A Review Article

: Nanotechnology is one of the fastest-growing and most promising modern technologies. It deals with the manufacturing and use of nanoparticles. Nanoparticles are generally known as small-sized particles possessing a size range of 1 to 100 nm. Due to their distinctive physicochemical and mechanical characteristics, they are utilized in various fields like agriculture, material science, food industry, medical, diagnostic, and cosmetic applications. One of the nanoparticles that is most frequently used nowadays is Zinc oxide nanoparticles. They have been explored for numerous biomedical applications, such as drug delivery, anticancer, antibacterial, antidiabetic, and bioimaging. Researchers expect that usage of Zinc oxide nanoparticles will expand so; the human body's exposure to them will increase. Zinc oxide . nanoparticles released into the environment could lead to adverse human and animal health effects. Recent studies concluded that Zinc oxide nanoparticles could cross some blood vital organs barriers and cell membranes, generate free radicals, and exhibit oxidative stress, cytotoxicity, and genotoxicity. Therefore, great attention must be taken to assess the toxicological aspects of nanoparticles.
Optimal rejection of stochastic and deterministic disturbances

The problem of optimal H 2 rejection of noisy disturbances while asymptotically rejecting constant or sinusoidal disturbances is considered. The internal model principle is used to ensure that the expected value of the output approaches zero asymptotically in the presence of persistent deterministic disturbances. Necessary conditions are given for dynamic output feedback controllers that minimize an H 2 disturbance rejection cost plus an upper bound on the integral square output cost for transient performance. The necessary conditions provide expressions for the gradients of the cost with respect to each of the control gains. These expressions are then used in a quasi-Newton gradient search algorithm to find the optimal feedback gains.
Commodity Price Shocks and Imperfectly Credible Macroeconomic Policies in Commodity-Exporting Small Open Economies

In this paper, we analyze how lack of credibility and transparency of monetary and fiscal policies undermines the effectiveness of macroeconomic policies to isolate the economy from commodity price fluctuations. We develop a general equilibrium model for a commodity-exporting economy where macro policies are conducted through rules. We show that the responses of output, aggregate demand, and inflation to an increase in commodity price are magnified when these rules are imperfectly credible and lack transparency. If policies are imperfectly credible, then transparency helps private agents to learn the systematic behavior of the autorities, reducing the effects of commodity prices shocks. Coherent with the model, we show cross-country evidence that monetary policy transparency and fiscal credibility reduce the incidence of export price volatility on output volatility. Also, our results indicate that having an explicit fiscal rule and an inflation targeting regime contribute to isolate the economy from terms of trade fluctuations.
On the free‐edge effect in piezoelectric laminated plates

The present paper considers the effect of electromechanical coupling on the interlaminar stresses and the electric field strengths at free edges of laminated plates with piezoelectric material properties. The results of coupled and uncoupled piezoelectric analyses performed by use of the finite element method are compared. Exemplarily, a symmetric cross‐ply and a symmetric angle‐ply laminate are investigated under uniaxial tension and without any electrical loading. It is shown that the interlaminar stresses at the free edge are significantly higher in the coupled case for the symmetric cross‐ply laminate, whereas the coupling effect for the symmetric angle‐ply laminate is of minor significance. In addition, the occurrence of electric field strengths with singular character is revealed. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
The He II 1640 Å multiplet observed from solar prominences

We describe an analysis of EUV spectra of solar prominences taken with the SO82-B instrument on Skylab, with special attention to the 1640 A 2l-3l'multiplet of He II. It appears that the line intensities emitted from plasma at temperatures between 2×10 4 and 4×10 4 K can be explained by an ionization equilibrium model, incorporating photoexcitation and photoionization by incident radiation from the solar disk. With this interpretation, the data are consistent with an abundance for He of 0.1 relative to H
A Sequential Testing Procedure for a System's State Identification

The system and its components have only two states: complete success or complete failure. The components' states are random variables and the system's state depends deterministically on the states of its elements. This paper assumes the state of the system is unknown and presents a sequential testing procedure of the components in order to determine the system's state. The procedure minimizes the expected number of necessary tests for a wide class of systems. The procedure is needed when the system is entirely or partially consumed upon its use, e.g., the firing of a missile, and one wishes to know the system's state without actually operating the system.
Color characteristics of costumes for Korean folk festivals and color consciousness of Koreans

The purpose of this study was to identify the color characteristics of Korean culture, the color consciousness of Korean people based on their arche-pattern sentiment, and to analyze the colors of the costumes of Korean folk festivals, which clearly suggest the archetype of Korean tradition. The range of this study is focused on Korea's important intangible cultural assets in which the colors used in folk festivals were fully expressed, and 20 folk games and plays were selected from among different festival events. Hundred and fifteen pictures from these 20 folk games/plays were used to extract the costume colors and conduct color analyses. Among 647 colors extracted in total, this article used 199 colors after excluding overlapping colors. The results show that Korean folk festivals have served as the medium of nondifferentiation that goes beyond the differentiated order of reality. Costumes for these Korean folk festivals, such as folk games and folk plays, have a sacred meaning as ritualistic robes. Five element colors in these costumes for the Korean folk festival are used as a means of circulatory thinking and as a symbol of Chaos—the very origin of undifferentiated thinking—beyond one's daily lives. It was found that these highly chromatic five element colors have always been used, wherever this undifferentiated thinking was strongly expressed. Delivering visually strong impacts, these five element colors symbolize the concept of the Arche-pattern theory, being related to infinite freedom without any restrictions. © 2010 Wiley Periodicals, Inc.

The IRC +10216 Circumstellar Envelope. III. Infrared Molecular Line Profiles

The 10 μm spectrum (780-1240 cm −1 ) has been surveyed with a resolution of 0.009 cm −1 . Numerous molecular vibration-rotation transitions were detected in absorption by the circumstellar shell. Analysis of the line profiles by means of spectral synthesis from models revealed radial abundance ratio variations in some species. SiO is approximately uniformly mixed through the inner shell. SiH 4 and NH 3 are apparently produced in the region 10 to 40 R * , possibly by formation on grains. CS is very strongly depleted in the region 100-1000 R * , perhaps onto grains. From nondetection of H 2 the current mass-loss rate is constrained to be less than 4×10 −5 M ○. yr −1
Cooperation in the Infinitely Repeated Prisoners' Dilemma with Perturbations

Abstract Take the infinitely repeated prisoners′ dilemma that is perturbed with strategies of uniformly bounded recall only, including the "tit-for-tat" strategy (with a probability that is bounded away from zero in the perturbation). As the discount factor approaches one, the perturbation probability approaches zero, and epsilon approaches zero, the payoffs associated with the set of pure strategy epsilon-equilibria converge to the cooperative, efficient payoff vector. In addition, the existence of pure strategy epsilon-equilibria and Nash equilibria is guaranteed under a wide range of perturbations. Journal of Economic Literature Classification Numbers: C72, D11.
The Galton-Watson process conditioned on the total progeny

Let Zk denote the number in the kth generation of a Galton-Watson process initiated by one individual and let N be the total progeny, i.e., As n → ∞ the limiting behaviour of the process {Zk, 0 ≦ k ≦ n} conditioned on the event {N =n} is studied. The results obtained are of exactly the same form for the subcritical, critical and supercritical cases. This is in marked contrast to the analogous situation got by conditioning on non-extinction by the nth generation and letting n → ∞. In the latter case the limiting results differ in form for the critical and non-critical cases.
The Influence of Pornography Exposure Towards Female University Students

The purpose of this study is to investigate the influence of pornography exposure towards female university students in Malaysia’s setting. Data is collected from 875 female university students from three public universities in Malaysia. Quantitative research methodology is used in this study, utilising closed-ended questionnaires as the instrument. Raw data is analysed using descriptive and inferential statistics. Findings of this study show that there is a moderate positive relationship between pornography exposure and sexual activities among female university students. As hypothesised, there is also a positive relationship between pornography exposure and sexual desires among female university students. Furthermore, the association between pornography exposure and permissive sexual attitude among female university students is moderately positive. These results replicate the outcomes of past research studies even though respondents in this study are all female. The findings of this study enhance the understanding of pornography exposure and its influence towards female university students. It could be used as reference for the future development of strategies and intervention programs to reduce and mitigate its negative consequences.
Gold nanoparticle enhanced microwave modulation with 1.55μm light in graphene-based antenna

A gold nanoparticle enhanced microwave modulation with 1.55 μm light in graphene-based antenna has been studied in this paper. The modulation of antenna radiation is achieved by the conductivity tunable characteristic of graphene, and the conductivity of graphene is controlled by light. With the introduction of the gold nanoparticles for exciting optical wave localized enhancement, the interaction between the graphene and the light is enhanced. And then the Fermi level is enlarged, leading to the enhancement of the conductivity turning rage of graphene. At last, the modulation of microwave radiation is enhanced. In the simulation, as the Fermi level of graphene increases from 0.1 eV to 0.4 eV, the S11 coefficient of resonant point of antenna changes by 8 dB. In the experiment, the 0-29.4 mw 1550 nm light is used, the S11 coefficient of graphene antenna with gold nanoparticles changes by 1 dB, which is 2 times higher than that of graphene antenna without gold nanoparticles. The result demonstrates that the microwave modulation by light in graphene-based antenna could be enhanced by gold nanostructures with the localized surface plasmons.
DAMAGE ASSESSMENT OF MULTIPLE CRACKED BEAMS: NUMERICAL RESULTS AND EXPERIMENTAL VALIDATION

A method is presented in this paper which uses the modal parameters of the lower modes for the non-destructive detection and sizing of cracks in beams. Using a finite element model of the structure to calculate the dynamic behaviour analytically, it is possible to formulate the inverse problem in optimization terms and then to utilize a solution procedure employing genetic algorithms. The damage assessment technique has been applied both to simulated and to experimental data related to cantilevered steel beams, each one with a different damage scenario; i.e., the position and depth of the cracks. It is demonstrated that this method can detect the presence of damage and can estimate both the crack positions and sizes with satisfactory precision. The problems related to the tuning of the genetic search and to the virgin state calibration of the model are also discussed.
