A Robust Evolutionary Technique For Coupled And Multidisciplinary Design Optimisation Problems In Aeronautics

This paper reviews recent progress made in Evolutionary Algorithms (EAs) for single, multiobjective and Multidisciplinary Design Optimisation (MDO) problems. Specifically we discuss the integration and implementation of a Hierarchical Asynchronous Evolutionary Algorithm (HAPEA) to solve complex engineering problems which can be multi-modal, involve non-linear approximations that are non-differentiable or involve multiple objectives. The algorithm is based upon traditional evolution strategies with the incorporation of an asynchronous function evaluation for the solution. The algorithm is adaptable for multiple population of EAs with variable fidelity models and use the concepts of Game Theory to handle multi-objective problems. Initially we give some examples of the performance of the algorithm for representative single and multi-objective analytical test functions, which involve multiple local minima, discontinuous Pareto fronts or constraints and then two cases related to aircraft design are analyzed. Result indicate that the method is robust and efficient on its application for real world problems.
The spectral albedo of sea ice and salt crusts on the tropical ocean of Snowball Earth: 1. Laboratory measurements

The ice-albedo feedback mechanism likely contributed to global glaciation during the Snowball Earth events of the Neoproterozoic era (1 Ga to 544 Ma). This feedback results from the albedo contrast between sea ice and open ocean. Little is known about the optical properties of some of the possible surface types that may have been present, including sea ice that is both snow-free and cold enough for salts to precipitate within brine inclusions. A proxy surface for such ice was grown in a freezer laboratory using the single salt NaCl and kept below the eutectic temperature (−21.2°C) of the NaCl-H2O binary system. The resulting ice cover was composed of ice and precipitated hydrohalite crystals (NaCl · 2H2O). As the cold ice sublimated, a thin lag-deposit of salt formed on the surface. To hasten its growth in the laboratory, the deposit was augmented by addition of a salt-enriched surface crust. Measurements of the spectral albedo of this surface were carried out over 90 days as the hydrohalite crust thickened due to sublimation of ice, and subsequently over several hours as the crust warmed and dissolved, finally resulting in a surface with puddled liquid brine. The all-wave solar albedo of the subeutectic crust is 0.93 (in contrast to 0.83 for fresh snow and 0.67 for melting bare sea ice). Incorporation of these processes into a climate model of Snowball Earth will result in a positive salt-albedo feedback operating between −21°C and −36°C.
Sub-Doppler Cooling of Fermionic Lithium

In our experimental approach to prepare strongly interacting Li-K mixtures, fermionic Li acts as the cooling agent. The high temperature of Li in the standard magneto-optical trap (MOT), operated on the D2 transition, limits the efficiency. To overcome this limitation, we implement a gray molasses cooling scheme on the D1 transition to reach sub-Doppler temperatures. In this technique, cooling arises from the Sisyphus effect in combination with a sharp cooling feature near the Raman transition where the two ground states (F = 1/2 and F = 3/2) are coupled via two lasers, blue detuned from the F ′ = 3/2 excited state of the D1 transition. With our experimental setup we can access a wide parameter range, in which the system can be characterized. By using separate light paths for the gray molasses and the MOT, we are able to investigate the influence of different polarizations and intensities on the D1 cooling feature. This enables us to cool our Li atoms from initially ∼ 250μK after the MOT to temperatures below 50μK. The very robust cooling technique offers us better starting conditions for our optical dipole trap, where Li sympathetically cools K.

We study the problem of computing semantic-preserving word clouds in which semantically related words are close to each other. We implement three earlier algorithms for creating word clouds and three new ones. We define several metrics for quantitative evaluation of the resulting layouts such as realized adjacencies, layout distortion, compactness, and uniform area use. We then compare all algorithms according to these metrics, using two different data sets of word documents from Wikipedia and ALENEX papers. We show that two of our new algorithms, based on extracting heavy subgraphs from a weighted graph, outperform all the others by placing many more pairs of related words so that their bounding boxes are adjacent. Moreover, this improvement is not achieved at the expense of significantly worsened measurements for the other metrics (distortion, compaction, uniform area use). The online system implementing the algorithms, all source code, and data sets are available at http://wordcloud.cs. arizona.edu.
Measurement of UHECR Mass Composition by TA FD Stereo

The Telescope Array is a hybrid detector consisting of Fluorescence Detectors (FDs) and Surface Detectors (SDs) to observe Ultra High Energy Cosmic Rays (UHECRs). FDs can measure longitudinal developments of cosmicray air showers directly. Xmax is the shower parameter that depends most on cosmic ray primary particle type. In this presentation, the most recent Xmax analysis of UHECR mass composition measured by TA FD stereo will be reported.
Betontechnische Einflüsse auf die Rißbildung infolge Hydratationswärme : influences of concrete technology on cracking due to the heat of hydration

1 Einleitung Zwangbeanspruchungen und Eigenspannungen infolge lastunabhängiger Verformungen (Schwinden, Temperatur) treten in vielen Betonbauteilen auf. Sie können durch konstruktive Maßnahmen nicht vermieden werden und sind deshalb bei der Bemessung zu berücksichtigen. Die Höhe der Zwangbeanspruchungen kann innerhalb bestimmter Grenzen durch ausführungstechnische und betontechnologische Maßnahmen begrenzt werden. Dies gilt besonders für Zwangbeanspruchungen infolge Abfließens der Hydrata
Adaptive Quadrature for the Chebyshev-Based Boundary Integral Equation Method

The recently presented Chebyshev-based Nyström method enables efficient, high-order discretization and solution of boundary integral equation problems. The approach handles far-interactions using the Nyström method by leveraging a high-order quadrature rule and treats the self-singular and near-singular interactions by expanding the unknown densities in terms of Chebyshev polynomials and precomputing the interactions of the integral operators against the Chebyshev-basis to high accuracy. This work presents an adaptive quadrature scheme which enables evaluating these precomputation integrals to a prescribed accuracy threshold. The approach is able to achieve the same accuracy as the prior static refined-integration-grid based method while being up to a factor of 6.6X faster for certain challenging geometries. An example is presented which highlights the advantages of the adaptive approach using the Magnetic Field Integral Equation (MFIE) to model a NURBS-based hummingbird CAD model.
Discussion Paper Series Immigrants and Legal Status : Do Personal Contacts Matter ? CPD 29

This paper addresses the effect of personal contacts on immigrants’ legal status by focusing particularly on the contacts’ direct links to legal status and indirect associations with the labor market. The overall effect of these contacts is theoretically unsigned and likely to vary across contact type and contextual factors. Our empirical analysis, based on unique Italian survey data on both documented and undocumented immigrants, tests two hypotheses regarding native contacts: (i) that they are more likely to be associated with a higher immigrant documentation probability and (ii) that they are more likely to introduce immigrants to jobs that facilitate access to employment-based legalization initiatives. Our results indicate that contacts with both natives and family members have a direct, positive, and quantitatively large effect on immigrant documentation probability, whereas contacts with members of the same ethnic group only indirectly increase documentation probability by raising the probability of employment. Our findings also support the hypothesis that native contacts connect immigrants with better jobs.
Statistical Analysis of Fracture Strength of Composite Materials Using Weibull Distribution

In this study, the fracture strength of a carbon-epoxy composite plate has been statistically analysed by Weibull distribution. Nineteen tension tests were carried out. The results obtained vary between 439 MPa and 552 MPa. Using Weibull distribution, the materials' reliability, in other words, the probability distribution according to which the material will fail was obtained.
A Digitally Assisted Multiplexed Neural Recording System With Dynamic Electrode Offset Cancellation via an LMS Interference-Canceling Filter

This article presents a low-power (LP) area-efficient implantable neural recording system that supports high-density neural implant (HDNI) applications. The system uses a time-division multiple access method to record from 16-neural electrodes simultaneously. A least mean squares (LMSs) algorithm is used to cancel the slowly varying electrode offsets from all channels simultaneously by using a single-tap digital adaptive filter (AF). The presented technique is fabricated in 65-nm CMOS technology and achieves a per-channel area of 0.00248 mm<sup>2</sup>; 68% of which is digital circuitry (and is thus scalable with technology). The overall system consumes 3.38 <inline-formula> <tex-math notation="LaTeX">$\mu \text{W}$ </tex-math></inline-formula> per channel while achieving 2.6 <inline-formula> <tex-math notation="LaTeX">$\mu \text{V}_{\mathrm {rms}}$ </tex-math></inline-formula> of input referred noise (IRN) in 10 kHz of bandwidth. The proposed system has a noise efficiency factor (NEF) of 1.83 and is fully integrated on-chip.
Atmospheric Mercury Speciation: Concentrations and Behavior of Reactive Gaseous Mercury in Ambient Air

Knowledge of atmospheric mercury speciation is critical to understanding its fate once released from point sources. The water-soluble compounds of Hg that exist in flue gases (termed reactive gaseous mercury, RGM) are subject to far greater local removal rates than is elemental Hg vapor, but few ambient air data exist. We developed a method using refluxing mist chambers to quantify the airborne concentrations of RGM in more than 250 ∼1-h samples under ambient conditions and summarize here the results of several RGM sampling campaigns in Tennessee and Indiana from 1992 to 1995. Measured levels of RGM were generally on the order of 50−200 pg/m3, representing about 3% of total gaseous mercury (TGM) and generally exceeding regional particulate Hg concentra tions. RGM exhibits significant correlations (p < 0.05) with temperature, solar radiation, O3, SO2, and TGM, suggesting seasonal trends similar to those of other regional air pollutants. The concentrations of RGM show reproducible diel trends, peaking durin.
PROTEIN CONTENT AND COMPOSITION OF WAXY RICE GRAINS

Rice is not only an important cereal as a major food worldwide but also valuable sources of nutritional and nutraceutical substances for human health. Protein is one of the major factors determining eating, processing and nutritional qualities of rice. Therefore, we examined effect of cultivar on the content and composition of proteins in waxy rice grains. Grains of eight waxy and one non-waxy Korean rice cultivars used in this study were produced at the N fertilizer level of 7 kg/10a. Crude protein content was higher in waxy cultivars than in the non-waxy cultivar. There was a considerable variation in crude protein contents among waxy cultivars, ranging from 8.6 to 9.7% in brown rice and from 8.1 to 8.5% in milled rice. There was also a significant varietal variation in content of the four protein fractions. The mean contents of albumin, globulin, prolamin, and glutelin fractions of waxy brown rice were 1.86, 0.50, 0.05, and 7.31%, respectively. Those of milled rice were 0.50, 0.30, 0.1, and 8.40%, respectively. Albumin, globulin, prolamin, and glutelin fractions for brown and milled rice were composed of seven, five, one, and five major bands, respectively, and no cultivaror tissuespecific variations were apparent in the fractional profiles detected on sodium dodecy sulfate-polyacrylamide gels. Thus, the varietal differences of total and fractional proteins were mostly contributed by quantitative rather than qualitative variations.
3282 ( RP-588 ) Measurement and Formulation of the Thermodynamic Properties of Refrigerants 134 a ( 1 , 1 , 1 , 2-Tetrafluoroethane ) and 123 ( 1 , 1-Dichloro-2 , 2 , 2-Trif luoroethane )

The thermodynamic properties of R134a and R123 are formulated using a modified Benedict.JNebb-_Flubin (MBWR) equation of state fit to experimental measure­ ments of the critical point, vapor pressure, saturated liquid and vapor volumes, superheated pressure-volume­ temperature (p-V-T) behavior, and second vif1a/ coefficients derived from p-V-T and sound speed measurements. The heat capacity of the ideal gas reference state is de­ termined from sound speed measurements on the low density vapor. Surface tensions are also presented. The experimental methods and results are summarized, com­ pared to the property formulation and, where 'possible, compared to other sources in the literature. Tables and diagrams of the thermodynamic properties of R134a a.nd R123, prepared using the MBWR equation of state, are presented. While the various measurements cover dif­ ferent ranges of temperature and pressure, the MBWR formulation is applicable in both the liquid and vapor phases at pressures up to 10,000 kPa (1500 psla); the applicable temperature range Is 233 to 450 K (-400 to 350F) for R134a and 255 to 450 K (0 to 350F) for R123.
S C ] 8 M ar 2 01 9 Quadratic Probabilistic Algorithms for Normal Bases

It is well known that for any finite Galois extension field K/F, with Galois group G = Gal(K/F), there exists an element α ∈ K whose orbit G · α forms an F-basis of K. Such an element α is called normal and G · α is called a normal basis. In this paper we introduce a probabilistic algorithm for finding a normal element when G is either a finite abelian or a metacyclic group. The algorithm is based on the fact that deciding whether a random element α ∈ K is normal can be reduced to deciding whether ∑ σ∈G σ(α)σ ∈ K[G] is invertible. In an algebraic model, the cost of our algorithm is quadratic in the size of G for metacyclic G and slightly subquadratic for abelian G.
Compact Directional Button Antenna Based on Curved Metamaterial for On-Body Wireless Power Transfer

$A$ compact directional button antenna based on curved Artificial Magnetic Conductor (AMC) is proposed to integrate easily into clothing for on-body wireless power transfer (WPT). The antenna is fed by the microstrip line, and a curved 3 × 3 AMC cells are adopted to reduce the horizontal size and reduce the spacing between the monopole and reflector. The monopole is loaded by two substrates, one is directly connected and has the same radius, while the other has a larger radius. An efficient design method is employed for the curved AMC cells such that the resulting radiation characteristics remain unaffected compared to those of the flat one. Finally, the influence of the human body is studied by using a human arm model.
Growth Factors in Acute Myeloid Leukemia

The role of myeloid growth factors, such as granulocyte colony-stimulating factor and granulocyte-macrophage colony-stimulating factor, in the management of acute myeloid and acute lymphoblastic leukemias has been evaluated extensively in multiple clinical trials. Growth factors have been given before, concurrently, or sequentially with chemotherapy with the goal of reducing the duration of neutropenia and consequently the incidence and severity of infections, and improving the rate of remissions and overall survival. They also have been studied as chemotherapy-sensitizing agents in an effort to recruit dormant myeloid stem cells into the sensitive phase of the cycle. Additionally, growth factors, shown to stimulate proliferation and differentiation of leukemia cells in vitro, were evaluated as monotherapy in patients with acute leukemia. Most studies show modest improvement in the duration of the neutropenia, which does not consistently correlate with the severity of infection, rate or duration of remissions, or disease-free and overall survival. Attempts to enhance the chemosensitivity of the leukemic cells and decrease drug resistance failed to improve the rate of remission and survival in several large series. However, more recent reports suggested an improved outcome in younger patients with acute myeloid leukemia with normal karyotype. Several anecdotal case reports have shown that growth factor monotherapy can induce a complete remission in patients with acute leukemia. Data from the published clinical trials do not seem to support emergence of drug-resistant leukemia, worsening toxicity, and bone marrow failure with growth factor administration.

Affinity Capillary Electrophoresis of β 2-glycoprotein I and Anionic Phospholipids Analytical chemistry Diploma work

In order to study the interactions between β2-glycoprotein I and negatively charged phospholipids in biological membranes, three different capillary electrophoresis modes, migration shift affinity capillary electrophoresis, partial filling affinity capillary electrophoresis and frontal analysis were tested. Liposomes were used to mimic biological membranes. Two different phospholipids were used to alter the liposome composition: L-alpha-phosphatidylcholine and Lalpha-phosphatidylserine. To recover β2-glycoprotein I it has earlier been shown that an acidic prewash of the capillary is necessary, as opposed to the usual basic prewash. In migration shift affinity CE the acidic prewash promoted capillary coating with phospholipids and this mode was found to be unsuitable for this study. No indications of capillary coating with phospholipids were observed when partial filling affinity CE mode was used. However, partial filling affinity CE did not offer enough time for β2gpI and the liposomes to interact. A clotting problem was suspected when β2-glycoprotein I and liposomes were allowed to interact in the frontal analysis capillary electrophoresis mode. However, studies with heparin and β2-glycoprotein I showed promising results indicating that CE-FA may be used to study the interaction. In order to use CE-FA to study interactions between β2-glycoprotein I and negatively charged phospholipids, alternative prewash steps and buffer systems must be evaluated.

EXTINCTION AND POLYCYCLIC AROMATIC HYDROCARBON INTENSITY VARIATIONS ACROSS THE H ii REGION IRAS 12063−6259

The spatial variations in polycyclic aromatic hydrocarbon (PAH) band intensities are normally attributed to the physical conditions of the emitting PAHs, however in recent years it has been suggested that such variations are caused mainly by extinction. To resolve this question, we have obtained near-infrared (NIR), mid-infrared (MIR), and radio observations of the compact H ii region IRAS 12063−6259. We use these data to construct multiple independent extinction maps and also to measure the main PAH features (6.2, 7.7, 8.6, and 11.2 μm) in the MIR. Three extinction maps are derived: the first using the NIR hydrogen lines and case B recombination theory; the second combining the NIR data with radio data; and the third making use of the Spitzer/IRS MIR observations to measure the 9.8 μm silicate absorption feature using the Spoon method and PAHFIT (as the depth of this feature can be related to overall extinction). The silicate absorption over the bright, southern component of IRAS 12063−6259 is almost absent while the other methods find significant extinction. While such breakdowns of the relationship between the NIR extinction and the 9.8 μm absorption have been observed in molecular clouds, they have never been observed for H ii regions. We then compare the PAH intensity variations in the Spitzer/IRS data after dereddening to those found in the original data. It was found that in most cases, the PAH band intensity variations persist even after dereddening, implying that extinction is not the main cause of the PAH band intensity variations.
Measurements of Heat Transfer Coefficients From Supercritical Carbon Dioxide Flowing in Horizontal Mini/Micro Channels

Heat transfer from supercritical carbon dioxide flowing in horizontal mini/micro circular tubes cooled at a constant temperature has been investigated experimentally. Six stainless steel circular tubes having inside-diameters of 0.50 mm, 0.70 mm, 1.10 mm, 1.40 mm, 1.55 mm, and 2.16 mm were tested. Measurements were carried out for the pressures ranging from 74 to 120 bar, the temperatures ranging from 20 to 110°C, and the mass flow rates ranging from 0.02 to 0.2 kg/min. It is found that the buoyancy effect was still significant, although supercriticalCO2 was in forced motion through the horizontal tubes at Reynolds numbers up to 10 5 . The experimental results also indicate that the existing correlations developed in the previous studies for large tubes deviate significantly from the experimental data for the present mini/micro tubes. Based on the experimental data, a correlation was developed for the axially averaged Nusselt number in terms of appropriate dimensionless parameters for forced convection of supercritical carbon dioxide in horizontal mini/micro tubes cooled at a constant temperature. @DOI: 10.1115/1.1423906#
CRIMINAL PROCEDURE MANAGEMENT BASED ON BPM SIMULATION RYSZARD ANTKIEWICZ, MICHAŁ DYK , RAFAŁ KASPRZYK,

The Polish criminal procedure is strictly based on the Polish Constitution and complex legislation. It involves many steps, phases and stages and creates very complex processes that are composed of multiple sub -processes and activities. Nowadays, the participants of the Polish criminal p rocedure are provided with modern IT limitedly. Increase the effectiveness of criminal justice is possible via changes in both organizational and procedural way, as well as through the IT technologies supporting the processing of informati on at any stage of a criminal proceeding. We propose two-way analysis of the criminal procedu r : modelling and simulation of the process similarly to Business Pro cesses Modelling (BPM), which forms the basis for measuring and assessing an effe ctiveness, and optimization based on hybrid models and methods: GAN/GERT with queuing theory and optimization. The practical result of this work is the workflow s ystem extended with the business process simulator.
