description: (Abridged) Under the hypothesis that MgII absorbers found near the minor axis of a galaxy originate in the cool phase of winds, we carry out a study to constrain the properties of large-scale outflows at redshift z >= 0.5 based on the observed relative motions of individual absorbing clouds with respect to the positions and orientations of the galaxies. We identify in the literature four highly inclined disk galaxies located within 50 kpc and with the minor axis oriented within 45 degrees of a background QSO sightline. Deep HST images of the galaxies are available for accurate morphologies of the galaxies. Echelle spectra of the QSO members are also available in public archives for resolving the velocity field of individual absorption clumps. Three galaxies in our sample are located at rho=8-34 kpc and exhibit strong associated MgII absorption feature with Wr(2796) >= 0.8 Å. One galaxy, located at an impact parameters rho=48 kpc, does not show an associated MgII absorber to a 3-sigma limit of Wr(2796)=0.01Å. Combining known inclination and orientation angles of the star-forming disks, and resolved absorption profiles of the associated absorbers at rho < 35 kpc, we explore the parameter space for the opening angle theta_0 and the velocity field of large-scale galactic outflows as a function of z-height, v(z). We find that the absorption profiles of the MgII doublets and FeII series are compatible with the gas being either accelerated or decelerated, depending on theta_0, though accelerated outflows are valid only for a narrow range of theta_0. Under an acceleration scenario, we compare the derived $v(z)$ with predictions from Murray et al. (2011) and find that if the gas is being accelerateted by the radiation and ram pressure forces from super star clusters, then the efficiency of thermal energy input from a supernova explosion is epsilon <= 0.01.

description: We present a detailed analysis of the partial coverage of the Q1232+082 (z_em =2.57) broad line region by an intervening H_2-bearing cloud at z_abs=2.3377. Using curve of growth analysis and line profile fitting, we demonstrate that the H_2-bearing component of the cloud covers the QSO intrinsic continuum source completely but only part of the Broad Line Region (BLR). We find that only 48\pm6 % of the C IV BLR emission is covered by the C I absorbing gas. We observe residual light (~6 %) as well in the bottom of the O I λ1302 absorption from the cloud, redshifted on top of the QSO Lyman-α emission line. Therefore the extent of the neutral phase of the absorbing cloud is not large enough to cover all of the background source. The most likely explanation for this partial coverage is the small size of the intervening cloud, which is comparable to the BLR size. We estimate the number densities in the cloud: n_H2~110 cm^{-3} for the H_2-bearing core and n_H ~30 cm^{-3} for the neutral envelope. Given the column densities, N(H2)=(3.71\pm0.97)\times10^19 cm^{-2} and N(H I)=(7.94\pm1.6)\times10^20 cm^{-2}, we derive the linear size of the H_2-bearing core and the neutral envelope along the line of sight to be l_H2~0.15^{+0.05}_{-0.05} pc and l_HI~8.2^{+6.5}_{-4.1} pc, respectively. We estimate the size of the C IV BLR by two ways (i) extrapolating size-luminosity relations derived from reverberation observations and (ii) assuming that the H_2-bearing core and the BLR are spherical in shape and the results are ~0.26 and ~0.18 pc, respectively. The large size we derive for the extent of the neutral phase of the absorbing cloud together with a covering factor of ~0.94 of the Lyman-α emission means that the Lyman-α BLR is probably fully covered but that the Lyman-α emission extends well beyond the limits of the BLR.

description: The monitoring and visualization is a very important component of any system since what is not measured and monitored cannot be managed and improved. This report (D4.1) describes the monitoring architecture for the CHESS SETUP from the lowest level of physical magnitudes, sensors, actuators and signals, to the highest level point of view of an operator that interacts with the system using an HMI (Human Machine Interface). The CHESS SETUP Project aims for efficient energy generation, accumulation and conditioning. Therefore, the main variable that will be monitored for this systems is energy, and one of the main targets of the monitoring system is the measurement of the energy transfers (distribution) within the components of the system, i.e., production, storage, conditioning and the final customer. In addition, the monitoring system has to take into account auxiliary measurements and management signals needed for controlling the individual devices of the system as well as for the alarm generation. Hence, this report includes information about the elements and variables which will be monitored, the used monitoring devices,
 and the system to process the obtained information.

description: Chandra X-ray observations of the high redshift (z =1.532) radio-loud quasar 3C270.1 in 2008 February show the nucleus to have a power-law spectrum, Gamma = 1.66 +/- 0.08, typical of a radio-loud quasar, and a marginally-detected Fe Kalpha emission line. The data also reveal extended X-ray emission, about half of which is associated with the radio emission from this source. The southern emission is co-spatial with the radio lobe and peaks at the position of the double radio hotspot. Modeling this hotspot including Spitzer upper limits rules out synchrotron emission from a single power-law population of electrons, favoring inverse-Compton emission with a field of ~11nT, roughly a third of the equipartition value. The northern emission is concentrated close to the location of a 40 deg. bend where the radio jet is presumed to encounter external material. It can be explained by inverse Compton emission involving Cosmic Microwave Background photons with a field of ~3nT, roughly a factor of nine below the equipartition value. The remaining, more diffuse X-ray emission is harder (HR=-0.09 +/- 0.22). With only 22.8+/-5.6 counts, the spectral form cannot be constrained. Assuming thermal emission with a temperature of 4 keV yields an estimate for the luminosity of 1.8E44 erg/s, consistent with the luminosity-temperature relation of lower-redshift clusters. However deeper Chandra X-ray observations are required to delineate the spatial distribution, and better constrain the spectrum of the diffuse emission to verify that we have detected X-ray emission from a high-redshift cluster.

description: Using piezoresponse force microscopy on epitaxial ferroelectric thin films, we have measured the evolution of domain wall roughening as a result of heat-quench cycles up to 735C, with the effective roughness exponent ζ changing from 0.25 to 0.5. We discuss two possible mechanisms for the observed ζ increase: a quench from a thermal 1-dimensional configuration, and from a locally-equilibrated pinned configuration with a crossover from a 2- to 1-dimensional regime. We find that the post-quench spatial structure of the metastable states, qualitatively consistent with the existence of a growing dynamical length scale whose ultra slow evolution is primarily controlled by the defect configuration and heating process parameters, makes the second scenario more plausible. This interpretation suggests that pinning is relevant in a wide range of temperatures, and in particular, that purely thermal domain wall configurations might not be observable in this glassy system. We also demonstrate the crucial effects of oxygen vacancies in stabilizing domain structures.

description: We demonstrate that almost 100 % of incident photons can interact with a monolayer of scatterers in a symmetrical environment. Nearly-perfect optical extinction through free-standing transparent nanorod arrays has been measured. The sharp spectral opacity window, in the form of a characteristic Fano resonance, arises from the coherent multiple scattering in the array. In addition, we show that nanorods made of absorbing material exhibit a 25-fold absorption enhancement per unit volume compared to unstructured thin film. These results open new perspectives for light management in high-Q, low volume dielectric nanostructures, with potential applications in optical systems, spectroscopy, and optomechanics.
A critical look at determinate theories of causation in law
Creators: name: Adams, Eric
Publisher: name: University of British Columbia
Year: 2009

description: My thesis critiques three determinate theories of causation in law: (1) the neutrality of Richard Wright's test for “causes-in-fact”; (2) the use of “abnormality” to distinguish causes from mere conditions in Hart and Honoré's (“H&H”) theory of proximate causation; and, (3) the substitution of “proximate causation” with an efficiency calculus in the Law and Economic literature. The first chapter argues that the way a causation question is formulated will largely determine the “facts” we receive from “necessity” or “sufficiency” tests for causation-in-fact. In the second chapter of my thesis I explore the concept of “normality” in H&H’s theory of proximate causation in Causation in the Law. I explore how H&H’s “normality” implies “normalization”, serves as a standard of conduct and affects substantive outcomes. The third chapter offers a case study for the second. It argues that Canadian courts tacitly weigh risks against rewards when constructing the meaning of the term “accident” in coverage decisions. This demonstrates how courts make policy choices when ostensibly applying an "empirical" standard of proximate cause. The fourth chapter considers the substitution of efficiency for proximate causation in the Law and Economics literature. It argues that efficiency cannot be reduced to a matter of empirical fact.

description: Motion in a one-dimensional (1D) microfluidic array is simulated. Water droplets, dragged by flowing oil, are arranged in a single row, and due to their hydrodynamic interactions spacing between these droplets oscillates with a wave-like motion that is longitudinal or transverse. The simulation yields wave spectra that agree well with experiment. The wave-like motion has an instability which is confirmed to arise from nonlinearities in the interaction potential. The instability's growth is spatially localized. By selecting an appropriate correlation function, the interaction between the longitudinal and transverse waves is described.

description: We discuss the $F$-matrices associated to the $R$-matrix of a general $N$-state vertex model whose statistical configurations encode $N-1$ U(1) symmetries. The factorization condition is shown for arbitrary weights being based only on the unitarity property and the Yang-Baxter relation satisfied by the $R$-matrix. Focusing on the N=3 case we are able to conjecture the structure of some relevant twisted monodromy matrix elements for general weights. We apply this result providing the algebraic expressions of the domain wall partition functions built up in terms of the creation and annihilation monodromy fields. For N=3 we also exhibit a $R$-matrix whose weights lie on a del Pezzo surface and have a rather general structure.

description: Chronic kidney disease (CKD) is a syndrome characterized by progressive and irreversible deterioration of renal function linked to slow destruction of renal parenchyma, eventually terminating in death when sufficient number of nephrons are damaged. Oxidative stress is commonly observed in CKD patients resulting from an imbalance between overproduction of reactive oxygen species (ROS) and impairment of defence mechanisms. Grape seed extract (GSE) is a polyphenolic mixture exhibiting antioxidant and anti-inflammatory properties. We conducted an interventional pilot study of supplementation with GSE capsules (GSE group, n = 23) or placebo (control group, n = 10) on CKD patients. Blood and urine samples were collected at baseline and after a six-month-long supplementation period to determine some renal function biomarkers, as well as antioxidant, anti-inflammatory and haematological parameters. GSE improved glomerular filtration rate (GFR) and proteinuria, increased the anti-oxidant status as assessed by high plasma catalase and superoxide dismutase and also lowered lipoperoxidation and carbonylation. GSE ameliorated inflammation by decreasing CRP, triglyceridemia and counteracted anemia and thrombocytopenia. Supplementation with 2 g GSE/day for six months improved some kidney function parameters of CKD patients and this beneficial effect of GSE seems to be mediated at least partly by its antioxidant and anti-inflammatory properties.

description: Pancreatic ductal adenocarcinoma (PDAC) remains one of the most aggressive and lethal malignant tumors all over the world, with a 5-year survival rate of less than 10%1,2. Usually diagnosed at an advanced stage, PDAC is highly resistant to current therapies, partly due to an extremely high rate of distant metastasis (>80%) at first diagnosis. The liver is the most frequent site of distant metastases for PDAC. Current therapeutic options for PDAC patients with liver metastasis are extremely limited3. Thus, understanding the molecular mechanisms underlying hepatic metastasis of PDAC is urgently needed to help us develop more effective treatments and improve survival for these patients with advanced disease.

description: Beim nicht-interaktiven Crowdsourcing senden Endgeräte einem Provider Daten in Echtzeit und ohne Benutzerinteraktion, wodurch sich Anforderungen an die Sicherheit und den Datenschutz ergeben. In dieser Arbeit werden diese Anforderungen erstmals vollständig definiert und anhand von zwei Szenarien veranschaulicht. Es kann unter anderem gezeigt werden, dass bei modernen Navigationssystemen ein Benutzer-Tracking möglich ist und Echtzeitverkehrsdaten unerkannt manipuliert werden können. Zur Vermeidung solcher Angriffe werden zwei Protokolle auf Basis von Zero-Knowledge Protokollen vorgestellt und deren Praktikabilität auf verschiedenen Endgeräten nachgewiesen. Die Implementierung von Zero-Knowledge Protokollen ist zeitaufwendig. Aus diesem Grund wird eine domänenspezifische Eingabesprache eingeführt, um die Beschreibung von Zero-Knowledge Protokollen zu vereinfachen. Ein Compiler übersetzt die Eingabesprache in eine beliebige Zielsprache. Dabei erfolgt die Beschreibung des Compilerzwischencodes durch spezielle Makros, wodurch bestehender C++ Code leichter als bei anderen Compilerkonzepten integriert werden kann. Auf Grund der speziellen Darstellung des Zwischencodes ist eine automatische Optimierung von rechenintensiven Langzahloperationen möglich. Durch Grafikkarten und die Einführung neuer Algorithmen lässt sich der Durchsatz an modularen Exponentiationen gegenüber einer CPU-Implementierung verzehnfachen.
description: In non-interactive crowdsourcing scenarios devices send data to a provider in real-time without user interaction, which leads to security and privacy demands. This thesis completely defines and illustrates these requirements for the first time using two scenarios. Among other things, it can be shown that user tracking is possible in modern navigation systems and that real-time traffic data can be manipulated unnoticed. In order to avoid such attacks two protocols are presented on the basis of zero-knowledge protocols and their practicality is proven on different devices. The implementation of zero-knowledge protocols is time-consuming. For this reason, a domain-specific input language is introduced in order to simplify the description of zero-knowledge protocols. A compiler translates the input language into an arbitrary target language. The intermediate code of the compiler is described by special macros, which make the integration of existing C++ code easier than in other compiler concepts. Due to the special presentation of the intermediate code, an automatic optimization of compute-intensive long-number operations is possible. Compared to a CPU implementation, graphics cards and the introduction of new algorithms increase the throughput of modular exponentiations by a factor of ten.

description: Context: Magnetohydrodynamic thermal modes may play an important role in the formation, plasma condensation, and evolution of solar prominences. Unstable thermal modes due to unbalance between radiative losses and heating can lead to rapid plasma cooling and condensation. An accurate description of the radiative loss function is therefore crucial for this process. Aims: We study the stability of thermal modes in unbounded and uniform plasmas with properties akin to those in solar prominences. Effects due to partial ionization are taken into account. Three different parametrizations of the radiative loss function are used. Methods: By means of a normal mode analysis, we investigate linear nonadiabatic perturbations superimposed on the equilibrium state. We find an approximate instability criterion for thermal modes, while the exact linear growth rate is obtained by numerically solving the general dispersion relation. The stability of thermal disturbances is compared for the three different loss functions considered. Results: Using up-to-date computations of radiative losses derived from the CHIANTI atomic database, we find that thermal modes may be unstable in prominences for lower temperatures than those predicted with previously existing loss functions. Thermal instability can take place for temperatures as low as 15,000 K, approximately. The obtained linear growth rates indicate that this instability might have an important impact on the dynamics and evolution of cool prominence condensations.

description: We present an innovative approach that simultaneously enables direct antenna frequency-hopped M-ary frequency shift keying (DAFH-MFSK) modulation and beamsteering through the use of time-modulated arrays (TMAs). The distinctive feature of our approach lies in the modulation of the TMA excitations with binary periodic sequences, which can be easily frequency-adjusted and time-delayed to simultaneously allow for DAFH-MFSK direct antenna modulation and beamsteering. Notably, our TMA proposal offers a distinct advantage over conventional architectures in terms of performance metrics, including reduced insertion losses and enhanced phase resolution for beamsteering, while also simplifying hardware complexity.

Our method offers a dramatic increase in data rate and demonstrates a path to new applications in highly dynamic environments. The performance of the device can largely be attributed to the high recapture efficiency of atoms from one interferometer measurement cycle to another.

description: The CHESS SETUP concept aims to achieve an energy efficient system to supply heating and hot water in buildings mainly from renewable sources. The proposed system is based on the optimal combination of solar energy production, heat storage and heat pump use and may have an auxiliary system as a back-up. However, the configuration of the system may be adapted and optimized according to the situation in different project types and locations. The integration with other energy sources and technologies should therefore be considered to understand the potential of replicating the system with the incorporation of some variables. The following energy sources and technologies have initially been considered as potentially appropriate for implementation and have therefore been researched to understand its operation, availability, efficiencies, costs, market status and overall integration with the CHESS SETUP system: Solar hybrid panels (PVT) Biomass Geothermal Waste heat Absorption cooling Combined Heat and Power (CHP) Photovoltaic panels and Air Source Heat Pump (ASHP) The integration of these with the CHESS SETUP system has been analyzed performing preliminary energy calculations to understand the potential energy and CO2 savings and the results are shown in ‘Chapter 3 Energy modelling results’.

description: Although the majority Kentucky’s citizens pay their fair share of motor vehicle registration taxes, there are indications that a number of citizens evade motor vehicle property and usage tax through a variety of means. Some individuals license their cars in states that have no, or very low, property taxes on motor vehicles; others abuse the use of temporary tags, or simply fail to renew the registration on their vehicles. As a result, Kentucky is losing income that would be used to repair the state’s roadways and fund local services such as schools, libraries, health departments, and police and fire services.  Despite the efforts of the Kentucky Department of Revenue and Kentucky State Police, collections from vehicle usage tax and property tax evaders have never reached their potential. This is primarily due to the limited resources available to these agencies and past technological challenges that prevented the ready identification of tax evaders. The objective of this research was to study new investigative techniques and technologies that are now available, and which could help to improve and streamline the Department of Revenue’s collection efforts.  There are more tools available now to compliance staff within the Department of Revenue that will facilitate efforts to identify and verify a person’s residence. However, a more concerted effort is necessary to increase the collection of vehicle property and usage taxes. These tools have made the process more efficient, but additional resource commitments must be made in order to ensure that tax evaders — once identified — ultimately pay their taxes, penalties and interest.

description: The Immersion Grating Infrared Spectrometer (IGRINS) is a revolutionary instrument that exploits broad spectral coverage at high-resolution in the near-infrared. There are no moving parts in IGRINS and its high-throughput white-pupil design maximizes sensitivity. IGRINS on the 2.7 meter Harlan J. Smith Telescope at McDonald Observatory is nearly as sensitive as CRIRES at the 8 meter Very Large Telescope. However, IGRINS at R=45,000 has more than 30 times the spectral grasp of CRIRES. The use of an immersion grating facilitates a compact cryostat while providing simultaneous H and K band observations with complete wavelength coverage from 1.45 - 2.45 microns. Here we discuss details of instrument performance and summarize the application of IGRINS to stellar characterization, star formation in regions like Taurus and Ophiuchus, the interstellar medium, and photodissociation regions. IGRINS has the largest spectral grasp of any high-resolution, near-infrared spectrograph, allowing us to study star formation and evolution in unprecedented detail. With its fixed format and high sensitivity, IGRINS is a great survey instrument for star clusters, high signal-to-noise (SNR>300) studies of field stars, and for mapping the interstellar medium. As a prototype for GMTNIRS on the Giant Magellan Telescope, IGRINS represents the future of high-resolution spectroscopy. In the future IGRINS will be deployed to numerous facilities and will remain a versatile instrument for the community while producing a rich archive of uniform spectra.

The work has involved an analysis of data provided by the B.C. Ministry of Energy, Mines and Petroleum Resources collected from oil and gas wells drilled in the Northeast region of British Columbia for the purpose of evaluating the potential to exploit geothermal energy in the region. The study area was narrowed to two gas fields near Fort Nelson – Clarke Lake and Milo. The objectives of the project have been 1. to investigate the geothermal potential of the area; and, 2. to examine if non-geothermal wells could be used to recover geothermal energy; Using data gathered from the gas well log records, temperature gradient and heat flow maps were successfully generated for the study area using ArcGIS. A preliminary reservoir assessment has been done based on these maps. The results show the region has notably high potential for a deep geothermal project using Enhanced Geothermal System (EGS) methodologies to produce significant amounts of electrical energy for a very long time in a sustainable fashion. It is recommended that additional exploration and exploitation drilling should be done at Clarke Lake to verify the conclusions and strengthen the assumptions about suitable local rock permeability and fluid availability at depth. With respect to geothermal energy production from spent oil and gas wells, there is currently insufficient temperature and fluid flow to either recover heat for a district heating system in the nearby community of Fort Nelson or to generate electricity using a Binary Cycle process. The quantity of heat is too low to be an economically viable investment while the temperature is too low at the current gas plants to technically generate power. The research has demonstrated that data from drilled oil and gas wells when studied can be used with confidence to evaluate the geothermal potential of a region and should be applied to other locations in British Columbia and elsewhere to produce similar temperature gradient and heat flow maps.

description: Exoplanet searches with dedicated instrumentation have made 1 m/s radial velocity (RV) precision routine. Yet, RVs for large samples of stars generally remain at the 1km/s level. The Immersion Grating Infrared Spectrometer (IGRINS) is a revolutionary instrument that exploits broad spectral coverage at high-resolution in the near-infrared. IGRINS on the 2.7 meter Harlan J. Smith Telescope at McDonald Observatory is nearly as sensitive as CRIRES at the 8 meter Very Large Telescope.

However, IGRINS at R=45,000 has more than 30 times the spectral grasp of CRIRES. The use of a silicon immersion grating facilitates a compact cryostat while providing simultaneous wavelength coverage from 1.45 - 2.45 microns. We have developed a pipeline to cross-correlate the more than 20,000 resolution elements in two IGRINS exposures and provide relative RVs with uncertainties of ~50m/s (<1% of a resolution element). Absolute RVs are limited by the zero point uncertainty, which is ~150m/s. IGRINS RVs will be provided for thousands of objects per year as a default procedure of the data reduction pipeline, creating a legacy product for multi-epoch studies of low-mass, stellar and substellar multiplicity.

Jets and Photons in ALICE

description: ALICE measured transverse momentum spectra of pi0 and eta mesons via the two photon decay in pp collisions at sqrt(s)=0.9, 2.76 and 7 TeV and Pb-Pb collisions at sqrt(sNN)=2.76 TeV. NLO pQCD calculations agree with p-p measurements at 0.9 TeV, but overestimate the data at 2.76 and 7 TeV. The nuclear modification factor for neutral pions shows a strong suppression of high-pt particle production in central Pb-Pb collisions. Raw spectra of charged particle jets have been measured in Pb-Pb collisions. Detailed studies of background fluctuations have been performed and will allow us to unfold the spectra even for low momentum cut offs, giving access to soft fragmentation products in quenched jets.

description: We report a comprehensive study of the electrical and magneto-transport properties of nanocrystals of La_0.67Ca_0.33MnO_3 (LCMO) (with size down to 15 nm) and La_0.5Sr_0.5CoO_3 (LSCO) (with size down to 35 nm) in the temperature range 0.3 K to 5 K and magnetic fields upto 14 T. The transport, magnetotransport and non-linear conduction (I-V curves) were analysed using the concept of Spin Polarized Tunnelling in the presence of Coulomb blockade. The activation energy of transport, Δ, was used to estimate the tunnelling distances and the inverse decay length of the tunnelling wave function (χ) and the height of the tunnelling barrier (Φ_B). The magnetotransport data were used to find out the magnetic field dependences of these tunnelling parameters. The data taken over a large magnetic field range allowed us to separate out the MR contributions at low temperatures arising from tunnelling into two distinct contributions. In LCMO, at low magnetic field, the transport and the MR are dominated by the spin polarization, while at higher magnetic field the MR arises from the lowering of the tunnel barrier by the magnetic field leading to an MR that does not saturate even at 14 T. In contrast, in LSCO, which does not have substantial spin polarization, the first contribution at low field is absent, while the second contribution related to the barrier height persists. The idea of inter-grain tunnelling has been validated by direct measurements of the non-linear I-V data in this temperature range and the I-V data was found to be strongly dependent on magnetic field. We made the important observation that a gap like feature (with magnitude ~ E_C, the Coulomb charging energy) shows up in the conductance g(V) at low bias for the systems with smallest nanocrystal size at lowest temperatures (T < 0.7 K). The gap closes as the magnetic field and the temperature are increased.

description: We combine surveys of the radio sky at frequencies 22 MHz to 1.4 GHz with data from the ARCADE-2 instrument at frequencies 3 to 10 GHz to characterize the frequency spectrum of diffuse synchrotron emission in the Galaxy. The radio spectrum steepens with frequency from 22 MHz to 10 GHz. The projected spectral index at 23 GHz derived from the low-frequency data agrees well with independent measurements using only data at frequencies 23 GHz and above. Comparing the spectral index at 23 GHz to the value from previously published analyses allows extension of the model to higher frequencies. The combined data are consistent with a power-law index beta = -2.64 +/- 0.03 at 0.31 GHz, steepening by an amount Delta beta = 0.07 every octave in frequency. Comparison of the radio data to models including the cosmic ray energy spectrum suggests that any break in the synchrotron spectrum must occur at frequencies above 23 GHz.

description: Kosteneffizienz hat nie an Relevanz als Wettbewerbsvorteil verloren, denn der Wettbewerb der Unternehmen mit Best-Cost-Ländern sowie die Produktvielfalt durch die Macht der Kunden haben in den letzten Jahren kontinuierlich zugenommen. Die Arbeit entwickelt daher ein theoretisches Framework mit dem Namen "extended axiomatic design" (EAD), der „engineering design theory“ und „economic firm theory“ integriert und damit eine umfangreiche Formalisierung von Produktprogrammen schafft. Die Verwendung des EAD zur Modellierung und Simulation ermöglicht die anschließend Untersuchung von Modularisierungsstrategien in Bezug auf Kosten, die effektive Auswahl von Designs von Kostensystemen und die Auswirkungen zufälliger Messfehler auf die kostenbasierte Entscheidungsfindung. Insgesamt widmet sich diese Arbeit der Entwicklung und dem Verständnis der Kosteneffizienz in Unternehmen durch die Untersuchung von Kostenmessung und -management.
description: Cost-effectiveness has never lost relevance as a competitive advantage because firms’ competition against best-cost countries as well as product variety from customers’ power have been continuously increasing over the last years. The thesis hence develops a theory-connecting framework called ‘extended axiomatic design’ (EAD) that integrates engineering design and economic firm theory and thereby composes an extensive formalization of product programs. Using the EAD for modeling and simulating allows examining modularization strategies in terms of costs, effective choices of cost system designs, and the impact of random measurement errors on cost-based decision-making. Overall, this thesis devotes to the development and understanding of cost-effectiveness in firms by examining cost measurement and management.

description: If $M$ is a compact smooth manifold and $X$ is a compact metric space, the Sobolev space $W^{1,p}(M,X)$ is defined through an isometric embedding of $X$ into a Banach space. We prove that the answer to the question whether Lipschitz mappings ${\rm Lip}\,(M,X)$ are dense in $W^{1,p}(M,X)$ may depend on the isometric embedding of the target.

description: Energy affects all aspects of life and the energy industry is a constantly evolving market with new policy, legislation, and directives being introduced by the government on a regular basis. Every project in any field should be developed and exploited under the requirements of the applicable legislations in order to accomplish and ensure that all the elements follow the mandatory rules. The aim of this Deliverable is to elaborate a guide with all the normative frameworks required and necessary for the design, construction, and maintenance of the CHESS-SETUP system in the countries of the three different pilots. The document is divided in two parts, one for each country, following a coherent order despite the small normative frameworks structure differences existing between each other. In each chapter the normative frameworks concerned are named and described in their lasts version, making particular emphasis to the parts and technical instructions that may apply to CHESS-SETUP project.

description: We have presented the non-equilibrium (time-dependent) cooling rate and ionization state calculations for a gas behind shock waves with $v \sim 50-150$ km s$^{-1}$ ($T_s \sim 0.5 - 6\times 10^5$ K). Such shock waves do not lead to the radiative precursor formation, i.e. the thermal evolution of a gas behind the shock waves are controlled by collisions only. We have found that the cooling rate in a gas behind the shock waves with $v \sim 50-120$ km s$^{-1}$ ($T_s \sim 0.5 - 3\times 10^5$ K) differs considerably from the cooling rate for a gas cooled from $T = 10^8$ K. It is well-known that a gas cooled from $T = 10^8$ K is thermally unstable for isobaric and isochoric perturbations at $T \simgt 2\times 10^4$ K. We have studied the thermal instability in a collisionally controlled gas for shock waves with $v \sim 50-150$ km s$^{-1}$. We have found that the temperature range, where the postshock gas is thermally unstable, is significantly modified and depends on both gas metallicity and ionic composition of a gas before shock wave. For $Z \simgt 0.1Z_\odot$ the temperature range, where the thermal instability criterion for isochoric perturbations is not fulfilled, widens in comparison with that for a gas cooled from $T = 10^8$ K, while that for isobaric perturbations remains almost without a change. For $Z\sim Z_\odot$ a gas behind shock waves with $v \simlt 65$ km s$^{-1}$ ($T_s \simlt 10^5$ K) is thermally stable to isochoric perturbations during full its evolution. We have shown that the transition from isobaric to isochoric cooling for a gas with $Z \simgt 0.1Z_\odot$ behind shock waves with $T_s = 0.5 - 3\times 10^5$ K proceeds at lower column density layer behind a shock wave than that for a gas cooled from $T = 10^8$ K.
