GOAL ORIENTED ADAPTIVITY FOR TROPICAL CYCLONES: THE RESONANT INTERACTION OF A TROPICAL CYCLONE AND A TROPOPAUSE FRONT

The development and motion of tropical cyclones (TCs) is influenced by processes on a large range of scales. Tropical cyclone motion is determined by the environmental flow on scales of several thousand kilometers whereas the genesis is particularly sensitive to inner-core convection on scales below several kilometers. The structure and intensification are influenced by the large-scale and the convective scale. Thus a multi-scale approach is essential to represent a tropical cyclone adequately. Adaptive techniques are a promising way to tackle such challenging multi-scale problems. We are investigating techniques for automatic local mesh adaptation controlled by goal functionals. The sensitivity information obtained with goal oriented methods is used to refine the mesh automatically in a way that minimizes the error of the numerical solution with respect to an arbitrary physical quantity of interest. The sensitivity information presents not only a way to optimize the mesh, but can also provide insight into the processes that affect the development and motion of TCs. In a joint mathematical-meteorological project we aim at applying goal-oriented techniques on problems related to tropical cyclones. Highly idealized TC scenarios are investigated, as the TC problem in its entirety is too complex and not sufficiently well understood to serve as a test problem. For this purpose we define barotropic TC problems that could benefit considerably from goal-oriented adaptivity. We perform non-adaptive high-resolution reference model runs for these scenarios which will be compared to adaptive calculations using different goal functionals. In the following we will first give a short overview of the goal oriented approach and present first results for a barotropic problem studied by Schubert et al. (1999). Then we focus on a second scenario, the interaction of a tropical cyclone with frontal waves. This problem is relevant for the extratropical transition of tropical cyclones and shows an interesting sensitivity to changes in the initial state.

Microelectromechanical inductors with high inductance density via mechanical energy storage

This paper reports the fabrication, characterization and modeling of microelectromechanical inductor (MEMI) devices, which employ electrodynamic coupling and mechanical energy storage to boost the apparent electrical inductance of electrical conductors. The microfabricated MEMI devices comprise an electrically conducting, mechanically suspended clamped–clamped copper beam that is placed in a transverse static magnetic field. Under an ac current excitation, the beam is forced to vibrate via the electrodynamic interactions between the electrical current and the static magnetic field. This electromechanical coupling results in a large apparent electrical inductance. The microfabrication and subsequent characterization of a variety of test structures is presented. The devices exhibit a peak quality factor up to 5.6 and net areal inductance densities of up to 3.5 µH mm−2. The experimentally observed behavior is compared against theoretical models using extracted system parameters.

2.1 - Real-Time Channel Sounding for Channel-Adaptive Data Links

The development of wideband mobile communications systems requires a good knowledge of the characteristics of the mobile channel as described by its impulse response. Such impulse response can be modeled as a tapped delay line with delays, amplitudes and phases associated with each tap. In order to obtain satisfactory estimates of these parameters and to determine delay spread, Doppler spread and the channel scattering function, a real-time channel sounder is required. This paper focuses on the hardware implementation of a real-time channel sounder, on an Innovative-DSP X6400M Software-Defined-Radio platform based on a Xilinx Virtex-6 FPGA. The real-time channel sounder has been developed in VHDL and implemented with Xilinx ISE AND Xilinx System Generator design, simulation and analysis softwares. In order to visualize the measured channel scattering function, a graphical user interface has been created. Testing of the channel sounder using a channel emulator allowed to verify the proper operation of the project.
Effect of polymorphism in IGF-1 gene on production traits in Polish Holstein-Friesian cattle.

Associations were studied between IGF-1 gene polymorphism and selected beef and milk production traits in Polish Holstein-Friesian (HF) cattle. The IGF-1 genotype was determined in a total of 662 HF cows, heifers and bulls. In month 8 of life, on 213 young animals of both sexes the 28-days feed intake and conversion test was conducted. Moreover, growth rate and beef production traits were determined on 131 HF bulls slaughtered at the age of 15 months. Referring to IGF-1 genotype also milk production traits were studied using performance data of 262 HF cows. Significant differences were found between IGF-1 genotypes in feed intake and feed conversion for growth. Animals carrying genotype BB consumed less dry matter, crude protein and energy per 1 kg body live weight gain than those of AA and AB genotypes. Moreover, the BB genotype appeared favourable for live weight gain during the test. The AB genotype was found positively associated with live body weight at slaughter, cold carcass weight, as well as weight of meat and fat in valuable cuts. Cows carrying AB genotype yielded daily more FCM and VCM milk and more milk fat and milk protein than those of AA and BB genotypes.
Strathmore UNIVERSITY THE IMPACT OF FOREIGN DEBT ON ECONOMIC GROWTH IN SUB SAHARAN AFRICA

This research carries out an empirical research on the impact of foreign debt on the economic growth of sub-Saharan Africa countries using cross sectional regression method suggested by Sala-i-Martin and Robert Barrow. The study also incorporates the Solow growth model. Tests for both debt overhang and crowding out effect are conducted on ten Sub Saharan African countries over the period of 1980-2010. The findings show that, although there is no significant evidence of debt overhang effect, a negative impact of foreign debt through the crowding out effect is sev~rely setting back economic growth in Sub Saharan Africa.
THE ROLE OF NITROGEN, OXYGEN , AND CARBON IN THE GROWTH OF LARGE-AREA GRAPHE E MONOLAYER 0 T COPPER CATALYST THESIS PRESENTED AS PARTIAL REQ IREMENT FOR THE DEGREE MASTER OF CHEMISTRY BY FILIP

THE ROLE OF ITROGEN, OXYGEN , AND CARBON IN THE GROWTH OF LARGE-AREA GRAPHENE MONOLAYER 0 COPPER CATALYST Since its isolation in 2004 graphene persist ntly remains a ynthesis challenge. In order to take advantage of its fu ll potential, high quality samples are requir d , i.e. large surfaces of mono-crystalline graphene. The Chemical Vapour Deposit ion growth method is one of the synthesi methods capable of atisfying those needs. Moreover, graphene's chemical n-doping opens its application potential. Using copper sheets as cataly t and several aliphatic precursors as carbon source, variable qualities of graphene can be produced. Methan and acetylene remain the most popular precursors. In this work it is shown that graphene synthesis from aliphatic alcohols (methanol , ethanol , 1-propanol) i possible, and that the presence of oxygen doesn 't infiu -nee the quality of the final product. Moreover , doped graphene is achieved using precursor containing nitrogen a a heteroatoms; the result ing material is high-quality and poly-crystalline, with different doping percentages. Finally, using a selected series of precursors , it is shown that the simultaneous presence of carbon , oxygen, and nitrogen behaves antagonistically to graphene's growth. The catalyst 's surface changes its topography and the spontaneous growth of the material is inhibited.
The dust and gas content of a disk around the young star HR 4796

We have used the James Clerk Maxwell Telescope (JCMT) in Hawaii to search at submillimetre wavelengths for continuum emission from dust, and spectral line emission from carbon monoxide (CO) gas, in the neighborhood of HR 4796A. This young star has a dusty disk with a central cavity, where planets may have formed. We detect the dust component a t a wavelength of 850 pm, and the inferred mass of solid material is > 0.25 Me. An upper limit for the CO J=3-2 rotational line implies less than 1-7 Me ( 5 0.003-0.02 Jupiter masses) of molecular HZ gas in the system. Thus, it is no longer possible to form new Jupiter-like gaseous giant planets around HR 4796A. If planet formation explains the observed dust cavity and lack of gas, then it must have occurred before the current stellar age of N 10 million years (Myr). A search was also made for CO J=3-2 emission around four other stars with dust excesses revealed by infrared measurements with the Infrared Astronomical Satellite (IRAS). Two were detected, both of them young sources with optical emission lines indicative of ongoing accretion of disk material onto the star. The gas mass lower limits are approximately 30 and 200 Earth masses, a t least an order of magnitude higher than for HR 4796A, illustrating the diversity of disk properties at ages of up to 10 Myr.
Description and performance of the low-energy transmission grating spectrometer on board Chandra

The Chandra spacecraft has been launched successfully on July 23, 1999. The payload consists of a high resolution X- ray telescope, two imaging detector systems in the focal plane and two transmission gratings. Each one of the two gratings can be put in the beam behind the telescope and the grating spectrometers are optimized for high and low energy, respectively. The Low Energy Transmission Grating Spectrometer consists of three parts: the high-resolution telescope, the transmission grating array and the detector, to read-out the spectral image.
O ct 2 01 5 Period and index for higher genus curves

Let K be a field; usually, we will consider it to be a number field. By a curve C over K, we shall mean a smooth projective geometrically integral curve. The period and index of C over K are two integer invariants which measure the failure of C to have rational points. Specifically, the index is the gcd of degrees of all effective divisors D ∈ DivC—that is, effective divisors which are rational over K. Equivalently, the index is the gcd of degrees [L : K], where L/K ranges over algebraic extensions such that C(L) 6= ∅. To see this, note that if P ∈ C(L), then D = σP is a rational effective divisor, where σ ranges over the embeddings of L into an algebraic closure of K; and conversely any minimal rational effective divisor is of this form. Also observe that if C already has K-points, then its index is 1. The period is less stringent: here we look at the smallest positive degree of rational divisor classes ; these are given by divisors which are linearly equivalent to their Galois conjugates. To see that the two invariants need not be the same, consider any conic over R without rational points, say the curve with affine piece x + y = −1. Certainly the index is 2, but as our curve is genus 0, there is a single divisor class of degree 1; namely, the class of a point. Therefore this class must be rational over R, and so the period is 1. As a rational divisor automatically belongs to a rational divisor class, we have P | I. Furthermore, the canonical class gives a rational divisor of degree 2(g− 1), so I | 2(g− 1). Lichtenbaum in [Lic69] found further conditions on the possible values of the period and index:
Experimental Studies of Two Force Control Algorithms for a Crack Sealing Robot in Highway Maintenance Technology

This paper presents experimental studies of force control algorithms for a crack sealing robot. The crack sealing robot is built as a test-bed to regulate contact force on the ground for a better task. Force tracking performances of two main force control algorithms, explicit force control and impedance force control, are compared experimentally. Experiments are conducted to test the robustness of control algorithms under unknown surface condition of the road. Experimental results show that performances of two force control algorithms are very comparable.
Pore-scale Modelling of Wettability Alteration during 1 Primary Drainage 2 3

19 While carbonate reservoirs are recognized to be weaklyto moderately oil-wet at the core20 scale, wettability distributions at the pore-scale remain poorly understood. In particular, the 21 wetting state of micropores (pores <5 μm in radius) is crucial for assessing multi-phase flow 22 processes, as microporosity can determine overall pore-space connectivity. While oil-wet 23 micropores are plausible, it is unclear how this may have occurred without invoking 24 excessively high capillary pressures. Here, we develop a novel mechanistic wettability 25 alteration scenario that evolves during primary drainage, involving the release of small polar 26 non-hydrocarbon compounds (e.g. alkylphenols, carbazoles) from the oil-phase into the 27 water-phase. We implement a diffusion and adsorption model for these compounds that 28 triggers a wettability alteration from initially water-wet to more intermediate–wet conditions. 29 This mechanism is incorporated in a quasi-static pore-network model to which we add a 30 notional time-dependency of the quasi-static invasion percolation mechanism. The model 31 qualitatively reproduces experimental observations where an early rapid wettability alteration 32 involving these small polar species occurred during primary drainage, preferentially near the 33 inlet. Interestingly, we are able to invoke clear differences in the primary drainage patterns by 34 varying both the extent of wettability alteration and the balance between the processes of oil 35 invasion and wetting change. Combined, these parameters dictate the initial water saturation 36 for waterflooding. Indeed, under conditions where oil invasion is slow compared to a fast and 37 relatively strong wetting change, the model results in significant non-zero water saturations, 38 even at high capillary pressures. This water trapping results from the removal of water 39 wetting films in the corners of angular pores. On the other hand, for relatively fast oil 40
DIFFERENCES IN BASAL AND STRESS-INDUCED HIPPOCAMPAL CELL PROLIFERATION IN ADULT LOW AND HIGH AGGRESSIVE MICE

Male wild house-mice, selected for long attack latency (LAL) and short attack latency (SAL), display distinctly different coping styles. This genetic trait in coping style was recently found to be associated with a differential regulation of the Hypothalamic-Pituitary-Adrenal (HPA) axis under basal and stress conditions, with LAL mice showing higher HPA reactivity. High glucocorticoid concentrations induced by stress suppress the proliferation rate of newborn cells in the dentate gyrus of adult rodents. Therefore, the hypothesis is tested that the differences in HPA activation between LAL and SAL mice are reflected in the rate of cell proliferation. Cell proliferation in the subgranular zone of the dentate gyrus, assessed by systemic application of bromodeoxyuridine (BrdU, one per day for three days), was almost two-fold lower in LAL mice than in SAL mice. This was, however, paralleled by significantly higher plasma corticosterone levels in LAL mice. To estimate basal cell proliferation in these mice, the endogenous proliferation marker Ki-67 was used. Under basal conditions, LAL mice had slightly lower (85%) numbers of Ki-67 positive cells in the SGZ than SAL mice. Forced swim stress for 5 min resulted 24 h later in a significant reduction in number of BrdU-positive cells in the subgranular zone of LAL but not of SAL mice. In conclusion, these results demonstrate that dentate gyrus cell proliferation rate reflects a genetic trait in coping style and stress responsiveness. Granule cell proliferation in SAL mice is resistant to stress, while it is further suppressed in LAL mice with high circulating corticosterone concentrations. This decreased granule proliferation displayed by the LAL mice may have implications for structure and function of the hippocampus during stress.

The article presents a framework which shows how competitive position is strengthened. The framework was approved in Lithuanian travel trade companies. The results of the empirical research revealed the expression of the consolidation of strategic positions of Lithuanian travel trade companies when striving for the competitive advantage in the market. Theoretical insights and empirical applicability are beneficial for tourism business companies to improve strategic positions and support for similar tourism research all around the world.
Examples of austere orbits of the isotropy representations for semisimple pseudo-Riemannian symmetric spaces

Harvey-Lawson and Anciaux introduced the notion of austere submanifolds in pseudo-Riemannian geometry. We give an equivalent condition for an orbit of the isotropy representations for semisimple pseudo-Riemannian symmetric space to be an austere submanifold in a pseudo-sphere in terms of restricted root system theory with respect to Cartan subspaces. By using the condition we give examples of austere orbits.
Traceability for Food Safety and Quality Assurance: Mandatory Systems Miss the Mark

Traceability systems are record-keeping systems that are primarily used to help keep foods with different attributes separate from one another. When information about a particular attribute of a food product is systematically recorded from creation through marketing, traceability for that attribute is established. Recently, policy makers in many countries have begun weighing the usefulness of mandatory traceability for managing such diverse problems as the threat of bio-terrorism, country-of-origin labelling, mad cow disease, and identification of genetically engineered foods. The question before policymakers is, When is mandatory traceability a useful and appropriate policy choice?

Preliminary studies of photocatalytic activity of gypsum plasters containing TiO2 co-modified with nitrogen and carbon

Abstract The conducted studies were focused on the development of the gypsum material exhibiting self-cleaning properties. To this end, the raw gypsum was mixed with unique TiO2-based photocatalysts, previously modified by nitrogen and/ or carbon doping. The photocatalytic activity of the obtained gypsum plasters was evaluated trough the degradation of model organic compound (Reactive Red 198) under UV-vis irradiation. The impact of the photocatalysts presence on the physicochemical properties of the obtained gypsum plasters was evaluated. Furthermore, the role of non-metals presence on the photocatalytic properties of the TiO2 was determined. It was confirmed that the addition of N,C co-modified titanium dioxide into gypsum bestows this material with self-cleaning properties. The highest dye removal rate was displayed by the gypsum plaster containing optimal amount (10 wt%) of co-modified TiO2/N,C photocatalyst, after 20 hours of UV-vis irradiation.
The world of trilobites and their Reflection in Philately

The aim of this book (a bilingual text, written in both German and English) is to present the trilobites depicted on stamps issued to date by postal authorities in various countries. Official postmarks, envelopes and postcards illustrating trilobites are also included. The book is the outcome of exhaustive research throughout the world. It is the largest compilation on this particular subject and one of the most important books on nature, comparable with other catalogues of minerals, birds, plants and other fossils, although the latter rarely provide such appropriate complementary information as that offered by this catalogue-book.
