description: Recently, the use and deployment of web services has dramatically increased. This is due to the easiness, interoperability, and flexibility that web services offer to the software systems, which other software structures don't support or support poorly. Web services discovery became more important and research conducted in this area became more critical. With the increasing number of published and publicly available web services, speed in web service discovery process is becoming an issue which cannot be neglected. This paper proposes a generic non-functional based web services classification algorithm. Classification algorithm depends on information supplied by web service provider at the registration time. Authors have proved mathematically and experimentally the usefulness and efficiency of proposed algorithm.

Year: 2011
Subjects: subject: Applications (stat.AP)
subject: FOS: Computer and information sciences

description: Recently, there has been an explosion of work on network routing in hostile environments. Hostile environments tend to be dynamic, and the motivation for this work stems from the scenario of IED placements by insurgents in a logistical network. For discussion, we consider here a sub-network abstracted from a real network, and propose a framework for route selection. What distinguishes our work from related work is its decision theoretic foundation, and statistical considerations pertaining to probability assessments. The latter entails the fusion of data from diverse sources, modeling the socio-psychological behavior of adversaries, and likelihood functions that are induced by simulation. This paper demonstrates the role of statistical inference and data analysis on problems that have traditionally belonged in the domain of computer science, communications, transportation science, and operations research.

description: The active element of an organic field effect transistor (OFET) is a polycrystalline transport layer. The crystallites are interrupted by grain boundaries (GB) that can act as traps or barriers to the charge-carriers. Their impact on charge transport and hence on the performance of the OFET is still not fully understood. Employing kinetic Monte Carlo studies, the authors set up well-defined test systems and explore how the parameters of the system, for example, the thickness of the GB, their fractional contribution to the overall film, and the energies of the GB relative to the crystallites, affect the performance of the OFET. It is found that these parameters control the position of the Fermi level, which is crucial in controlling whether the charge transport is confined to GB, or whether it takes place as a superposition between filamentary transport in the boundaries and delocalized transport in the crystallites, or as tunneling-mediated transport across the crystallites. Guidelines for the morphological optimization of the films for these different transport modes are derived.
Mapping contested terrain : mobilization and representation in transnational advocacy campaigns
Creators: name: Balasubramanian, Priyanjali
Publisher: name: University of British Columbia
Year: 2009

description: This paper identifies two blind spots in the literature on Transnational Advocacy Campaigns TACs): an overemphasis on the external political impacts of TACs and the lack of conceptual clarity on key analytical constructs such as mobilization and representation. These problems leave the internal dynamics of TACs under-theorized and prevent scholars from categorizing TAC constituencies beyond geographic and class-based dichotomies (for example: North-South, core-periphery). To address these limitations, the paper presents a typology that distinguishes TAC constituencies based on observed levels of mobilization and representation. Using two online TACs as case-studies, the paper demonstrates the feasibility of the typology and challenges the prevailing assumption in the TAC literature, which conflates the quantity of mobilization with the quality of representation. Overall, the paper pursues an integrated research approach that draws on the comparative method and international relations scholarship in its examination of advocacy in contemporary transnational politics.

description: Im Zuge eines immer stärker werdenden Wachstums von Städten müssen den daraus resultierenden Hitze-, Wasser- und Luftbelastungen mit innovativen Konzepten, wie dem Begrünen von ungenutzten Bauwerksoberflächen, sinnvoll entgegengewirkt werden. Das Ziel der vorliegenden Arbeit ist es Gebäudebegrünungssysteme hinsichtlich ihrer Leistungen und Anwendbarkeit zu untersuchen und den Bestand nutzbarer Flächen in Deutschland zu analysieren. Dazu wurden die, aus einer umfangreichen Literaturrecherche gewonnenen, Erkenntnisse auf Grundlage von Unternehmenskorrespondenzen in einem praxisbezogenen Kontext betrachtet. Die Ergebnisse zeigen, dass nahezu jedes Bauteil – unter Berücksichtigung einiger wesentlicher Anforderungen – begrünbar ist. Darüber hinaus deutet der nutzbare Flächenbestand an Bestands- und Neubauten in Deutschland ein großes Potenzial zukünftiger Begrünungen an. Die Nachfrage verschiedener Begrünungssysteme variiert jedoch stark, was u. a. auf unterschiedliche Kosten-Nutzen-Verhältnisse zurück geführt werden kann. Zukünftig müssen Themen wie der Brandschutz von Gebäudebegrünungen, die Nutzung von Synergieeffekten und die Verknüpfung von Pflanzen und Digitalisierung adressiert werden, um die Nutzung von Begrünungssystemen einfacher und attraktiver zu gestalten.
description: In the course of the ever-increasing growth of cities, the resulting heat, water and air pollution must be counteracted with innovative concepts, such as the greening of unused building surfaces. The aim of the present work is to examine building greening systems with regard to their performance and applicability as well as to analyze the extent of usable surfaces in Germany. For this purpose, the knowledge gained from literature research was considered in a practical context based on company correspondence. The results show that, by taking into account a few essential requirements, almost every roof and wall can be greened. In addition, the usable surface area of existing and new buildings in Germany indicates great potential for future greening. However, the demand for different greening systems varies greatly, which can be attributed to different cost-benefit ratios, among other things. In the future, topics such as fire protection for greening systems, the usage of synergy effects and the linking of plants and digitization must be addressed in order to make the application of building greening easier and more attractive.

description: We report the detection of pulsed gamma rays from the Crab pulsar at energies above 100 Gigaelectronvolts (GeV) with the VERITAS array of atmospheric Cherenkov telescopes. The detection cannot be explained on the basis of current pulsar models. The photon spectrum of pulsed emission between 100 Megaelectronvolts (MeV) and 400 GeV is described by a broken power law that is statistically preferred over a power law with an exponential cutoff. It is unlikely that the observation can be explained by invoking curvature radiation as the origin of the observed gamma rays above 100 GeV. Our findings require that these gamma rays be produced more than 10 stellar radii from the neutron star.

description: The behavior of an oxide fiber at elevated temperatures was analyzed before and after thermal exposures. The material studied was a mullite fiber developed for high-temperature applications, CeraFib 75. Heat treatments were performed at temperatures ranging from 1200°C to 1400°C for 25 hours. Quantitative high-temperature X-ray analysis and creep tests at 1200°C were carried out to analyze the effect of previous heat treatment on the thermal stability of the fibers. The as-received fibers presented a metastable microstructure of mullite grains with traces of alumina. Starting at 1200°C, grain growth and phase transformations occurred, including the initial formation of mullite, followed by the dissociation of the previous alumina-rich mullite phase. The observed transformations are continuous and occur until the mullite phase reaches a state near the stoichiometric 3/2 mullite. Only the fibers previously heat treated at 1400°C did not show further changes when exposed again to 1200°C. Overall, the heat treatments increased the fiber stability and creep resistance but reduced the tensile strength. Changes observed in the creep strain vs. time curves of the fibers were related to the observed microstructural transformations. Based on these results, the chemical composition of the stable mullite fiber is suggested.

description: We report on gamma-ray observations of the supernova remnant (SNR) RX J0852.0-4622 with the Large Area Telescope (LAT) aboard the Fermi Gamma-ray Space Telescope. In the Fermi LAT data, we find a spatially extended source at the location of the SNR. The extension is consistent with the SNR size seen in other wavelengths such as X-rays and TeV gamma rays, leading to the identification of the gamma-ray source with the SNR. The spectrum is well described as a power law with a photon index of Gamma = 1.85 +/- 0.06 (stat) (+0.18,-0.19) (sys), which smoothly connects to the H.E.S.S. spectrum in the TeV energy band. We discuss the gamma-ray emission mechanism based on multiwavelength data. The broadband data can be fit well by a model in which the gamma rays are of hadronic origin. We also consider a scenario with inverse Compton scattering of electrons as the emission mechanism of the gamma rays. Although the leptonic model predicts a harder spectrum in the Fermi LAT energy range, the model can fit the data considering the statistical and systematic errors.

description: This paper studies maximisation of an average-cost-per-unit-time ergodic functional over impulse strategies controlling a Feller-Markov process. The uncontrolled process is assumed to be ergodic but, unlike the extant literature, the convergence to invariant measure does not have to be uniformly geometric in total variation norm; in particular, we allow for non-uniform geometric or polynomial convergence. Cost of an impulse may be unbounded, e.g., proportional to the distance the process is shifted. We show that the optimal value does not depend on the initial state and provide optimal or $\ve$-optimal strategies.

description: Both humans and artificial systems frequently use trial and error methods to problem solving. In order to be effective, this type of strategy implies having high quality control knowledge to guide the quest for the optimal solution. Unfortunately, this control knowledge is rarely perfect. Moreover, in artificial systems-as in humans-self-evaluation of one's own knowledge is often difficult. Yet, this self-evaluation can be very useful to manage knowledge and to determine when to revise it. The objective of our work is to propose an automated approach to evaluate the quality of control knowledge in artificial systems based on a specific trial and error strategy, namely the informed tree search strategy. Our revision approach consists in analysing the system's execution logs, and in using the belief theory to evaluate the global quality of the knowledge. We present a real-world industrial application in the form of an experiment using this approach in the domain of cartographic generalisation. Thus far, the results of using our approach have been encouraging.

description: Multi--wavelength studies of energetic solar flares with seismic emissions have revealed interesting common features between them. We studied the first GOES X--class flare of the 24th solar cycle, as detected by the Solar Dynamics Observatory (SDO). For context, seismic activity from this flare (SOL2011-02-15T01:55-X2.2, in NOAA AR 11158) has been reported in the literature (Kosovichev, 2011; Zharkov et al., 2011). Based on Dopplergram data from the Helioseismic and Magnetic Imager (HMI), we applied standard methods of local helioseismology in order to identify the seismic sources in this event. RHESSI hard X-ray data are used to check the correlation between the location of the seismic sources and the particle precipitation sites in during the flare. Using HMI magnetogram data, the temporal profile of fluctuations in the photospheric line-of-sight magnetic field is used to estimate the magnetic field change in the region where the seismic signal was observed. This leads to an estimate of the work done by the Lorentz-force transient on the photosphere of the source region. In this instance this is found to be a significant fraction of the acoustic energy in the attendant seismic emission, suggesting that Lorentz forces can contribute significantly to the generation of sunquakes. However, there are regions in which the signature of the Lorentz-force is much stronger, but from which no significant acoustic emission emanates.

We characterize this subset and find some useful equivalences. Moreover, we explore properties concerning the action of this subset on sequences of m elements. In particular we describe sequences that share some special symmetries which can be useful in the study of combinatorial properties in graded Lie algebras.

description: In dieser Arbeit wird ein intelligentes Hybridmaterial auf Basis von nanoporösen Gold in einem wässrigen Elektrolyt vorgestellt, dessen Steifigkeit und Festigkeit reversibel durch externe Signale eingestellt werden können. Die Durchstimmbarkeit dieser effektiven mechanischen Eigenschaften wird über das Anlegen von elektrischen Potentialen an der großen Gold-Elektrolyt Grenzfläche innerhalb des Werkstoffes realisiert. Auf diese Art lässt sich der Oberflächenzustand durch elektrische Polarisation und Ionensadsorption kontrollieren. Die Verformungsexperimente wurden in situ in einer elektrochemischen Zelle, eingebaut in einen dynamisch-mechanischen Analysator und in einer mechanischen Prüfmaschine, durchgeführt. Die Ergebnisse der in situ Experimente zeigen, dass die Oberflächenexzesselastizität die effektive elastischen Antwort von Nanostrukturen beeinflusst während auf die Plastizität die Oberflächenspannung wesentlich einwirkt.
description: This study highlights a smart hybrid material based on nanoporous gold in an aqueous electrolyte whose stiffness and strength are reversibly tuned by external stimuli. The tunability of these effective mechanical properties is realized via application of electric potentials to the large gold-electrolyte interface of the material, and consequent control of the surface state through electrical polarization and adsorption. The experiments are implemented in situ under environmental control in a dynamic mechanical analyzer and a mechanical testing device. The results of the in situ experiments provide conclusive evidence for the impact of surface excess elasticity on the effective elastic response of nanostructures and support a hypothesis that surface tension is a dominant factor in controlling their plasticity.

description: We investigate the effect of new physics interacting with both Dark Matter (DM) and neutrinos at DM direct detection experiments. Working within a simplified model formalism, we consider vector and scalar mediators to determine the scattering of DM as well as the modified scattering of solar neutrinos off nuclei. Using existing data from LUX as well as the expected sensitivity of LUX-ZEPLIN and DARWIN, we set limits on the couplings of the mediators to quarks, neutrinos and DM. Given the current limits, we also assess the true DM discovery potential of direct detection experiments under the presence of exotic neutrino interactions. In the case of a vector mediator, we show that the DM discovery reach of future experiments is affected for DM masses $m_χ\lesssim 10$ GeV or DM scattering cross sections $σ_χ\lesssim 10^{-47}$ cm$^2$. On the other hand, a scalar mediator will not affect the discovery reach appreciably.

KM and WEB 2.0 methods for project-based learning. MESHAT : a monitoring and experience sharing tool

Year: 2011
Subjects: subject: Computers and Society (cs.CY)

description: Our work aims at studying tools offered to learners and tutors involved in face-to-face or blended project-based learning activities. To understand better the needs and expectations of each actor, we are especially interested in the specific case of project management training. The results of a course observation show that the lack of monitoring and expertise transfer tools involves important dysfunctions in the course organisation and therefore dissatisfaction for tutors and students (in particular about the acquisition of knowledge and expertise). So as to solve this problem, we propose a personalised platform (according to the actor: project group, student or tutor), which gives information to monitor activities and supports the acquisition and transfer of expertise. This platform is based on Knowledge Management (KM) and Web 2.0 concepts to support the dynamic building of knowledge. KM is used to define the learning process (based on the experiential learning theory) and the way the individual knowledge building is monitored (based on metacognitive concepts). Web 2.0 is used to define the way the experience is shared. We make the hypothesis that this approach improves the acquisition of complex skills (e.g. management, communication and collaboration), which requires a behavioural evolution. We aim at making the students become able 'to learn to learn' and evolve according to contexts. We facilitate their ability to have a critical analysis of their actions according to the situations they encounter.

description: Purpose: Current inverse planning methods for IMRT are limited because they are not designed to explore the trade-offs between the competing objectives between the tumor and normal tissues. Our goal was to develop an efficient multiobjective optimization algorithm that was flexible enough to handle any form of objective function and that resulted in a set of Pareto optimal plans. Methods: We developed a hierarchical evolutionary multiobjective algorithm designed to quickly generate a diverse Pareto optimal set of IMRT plans that meet all clinical constraints and reflect the trade-offs in the plans. The top level of the hierarchical algorithm is a multiobjective evolutionary algorithm (MOEA). The genes of the individuals generated in the MOEA are the parameters that define the penalty function minimized during an accelerated deterministic IMRT optimization that represents the bottom level of the hierarchy. The MOEA incorporates clinical criteria to restrict the search space through protocol objectives and then uses Pareto optimality among the fitness objectives to select individuals. Results: Acceleration techniques implemented on both levels of the hierarchical algorithm resulted in short, practical runtimes for optimizations. The MOEA improvements were evaluated for example prostate cases with one target and two OARs. The modified MOEA dominated 11.3% of plans using a standard genetic algorithm package. By implementing domination advantage and protocol objectives, small diverse populations of clinically acceptable plans that were only dominated 0.2% by the Pareto front could be generated in a fraction of an hour. Conclusions: Our MOEA produces a diverse Pareto optimal set of plans that meet all dosimetric protocol criteria in a feasible amount of time. It optimizes not only beamlet intensities but also objective function parameters on a patient-specific basis.

description: Spreadsheets offer a supremely successful democratisation platform, placing the manipulation and presentation of numbers within the grasp of users that have little or no mathematical expertise or IT experience. What appears to be almost completely lacking within a "normal" solution built using Excel default settings is the deployment of any structure that extends beyond a single-cell formula. The structural elements that allow conventional code to scale without escalating errors appear to be absent. This paper considers the use of controversial or lesser-used techniques to create a coherent solution strategy in which the problem is solved by a sequence of formulas resembling the steps of a programmed language.

description: In a laboratory experiment, water-ice aggregates are trapped in a vacuum chamber at a pressure of 2 mbar due to photophoresis and thermophoresis. The particles are located between a Peltier element at the bottom at 250 K and a reservoir of liquid nitrogen at the top at 77 K. Particle sizes vary between 20 micrometres and a few hundred micrometres. It is found that 95% of all the particles rotate about their vertical axis. A qualitative model is developed which explains why particles should mainly align to and rotate around the vertical. The results imply that rotation does not decrease the vertical strength of photophoretically driven motion in, e.g., protoplanetary discs.

description: We present for the first time the concept of a seeded γ quantum Free-Electron-Laser (QFEL) at 478 keV, which has very different properties compared to a classical. The basic concept is to produce a highly brilliant γ beam via SASE. To produce highly intense and coherent γ beam, we intend to use a seeded FEL scheme. Important for the production of such a γ beam are novel refractive γ -lenses for focusing and an efficient monochromator, allowing to generate a very intense and coherent seed beam. The energy of the γ beam is 478 keV, corresponding to a wavelength in the sub-Ångstrøm regime (1/38 Å). To realize a coherent γ beam at 478 keV, it is necessary to use a quantum FEL design. At such high radiation energies a classical description of the γ-FEL becomes wrong.

AIDS doesn't kill its customer : understanding barriers to access and adherence to HIV treatment among young people living in peri-Urban Uganda
Creators: name: Carter, Simone
Publisher: name: University of British Columbia
Year: 2009

description: Introduction: Uganda’s current success story in its battle against the HIV/AIDS epidemic is being questioned as recent research has estimated a possible increase in both prevalence and incidence across the country, specifically within the rural southwest. Rakai district has long been recognized as the Ugandan epicentre of HIV/AIDS and appears to again be in a vulnerable positive. As universal care to free HIV treatment has only been available in Uganda in 2004, there remains a paucity of literature understanding the current barriers to access and adherence to HIV treatment programs, especially among young people living in the heavily affected southwestern community of Lyantonde. Therefore, objectives of this thesis were to: 1. Investigate the current barriers young men and women experience when attempting to access HIV treatment and care in town;(2) Document the barriers young women and men living in this peri-urban setting experience when attempting to adhere to HIV treatment while living in town; (3) Develop community appropriate recommendations to address the results found within this study. Results: Participants not accessing treatment identified three barriers to treatment access: relationship-based fears, workplace-based fears and food insecurity leading to treatment attrition. None of the participants who were accessing treatment at the time of the study were able to remain adherent to their treatment, all of which reported that food insecurity was their only barrier to adherence. Discussion: these data indicate that the conditions for young people living with HIV/AIDS in Lyantonde remain incredibly difficult and, despite free treatment availability, many are not able to access care and those who are, face such food security-related barriers that they are unable to adhere to their treatment. Recommended actions include community based farming programs for young people living with HIV/AIDS, small household farming workshops, micro-credit groups for young people and finally the training of couples to offer dual counselling for both concordant and discordant couples during HIV/AIDS educational workshops and testing times.

description: We study current-induced vibrational cooling, heating, and instability in a donor-acceptor rectifying molecular junction using a full counting statistics approach. In our model, electron-hole pair excitations are coupled to a given molecular vibrational mode which is either harmonic or highly anharmonic. This mode may be further coupled to a dissipative thermal environment. Adopting a master equation approach, we confirm the charge and heat exchange fluctuation theorem in the steady-state limit, for both harmonic and anharmonic models. Using simple analytical expressions, we calculate the charge current and several measures for the mode effective temperature. At low bias, we observe the effect of bias-induced cooling of the vibrational mode. At higher bias, the mode effective temperature is higher than the environmental temperature, yet the junction is stable. Beyond that, once the vibrational mode (bias-induced) excitation rate overcomes its relaxation rate, instability occurs. We identify regimes of instability as a function of voltage bias and coupling to an additional phononic thermal bath. Interestingly, we observe a reentrant behavior where an unstable junction can properly behave at a high enough bias. The mechanism for this behavior is discussed.

description: Loewner driving functions encode simple curves in 2-dimensional simply connected domains by real-valued functions. We prove that the Loewner driving function of a $C^{1,β}$ curve (differentiable parametrization with $β$-Hölder continuous derivative) is in the class $C^{1,β-1/2}$ if $1/2<β\leq 1$, and in the class $C^{0,β+ 1/2}$ if $0 \leq β\leq 1/2$. This is the converse of a result of Carto Wong and is optimal. We also introduce the Loewner energy of a rooted planar loop and use our regularity result to show the independence of this energy from the basepoint.

description: Um den Anforderungen der deutschen Offshore-Windindustrie gerecht zu werden, besteht der Bedarf an individuell zu diesem Zweck entworfenen und gebauten Offshore-Windpark-Errichterschiffen. Eine der primären Entwurfsrandbedingungen dieser Schiffe ist das dynamische Positionieren (DP). Für die korrekte Dimensionierung von DP-Systemen sollten bereits im frühen Schiffsentwurf statische und dynamische Berechnungen durchgeführt werden. Zu diesem Zweck werden als Eingangsgrößen unter anderem Zeitreihen und zeitliche Mittelwerte der horizontalen Wellendriftkräfte und des Wellendriftgiermoments benötigt. Hierfür wird eine Berechnungsprozedur auf Basis der Streifenmethode in Kombination mit einer Korrektur für kurze Wellen vorgestellt und mit Versuchsergebnissen für den SIETAS TYP 187 validiert.
description: In order to fulfill the requirements of the German offshore wind industry individually designed and constructed offshore wind farm installation vessels are needed. One of the primary design constraints of these ships is dynamic positioning (DP). For the correct design of DP systems static and dynamic calculations should already been performed during the early ship design. Among other input data time series and time averaged mean values of the horizontal wave drift forces as well as the wave drift yaw moment are needed. For this a calculation procedure based on strip theory in combination with a correction for short waves is presented and validated with experimental results for the SIETAS TYPE 187.

description: Contemporary psychological models of a person's identity draw upon the Western conception of a person who is an autonomous, self­bounded individual, a center of multiple inputs, able to master and control her or his environment. Identity has been reified into an entity that could be mapped out and neatly categorized into hierarchical invariant stages. The approach adopted in the present research rejected this realist and essentialist view of identity, and instead, conceptualized identity as discursively produced and actively negotiated by speakers in everyday conversations. To understand the ways in which identity might be constructed, maintained or resisted in everyday talk, the project examined the discursive practices in which speakers engaged. The project involved seven focus groups of young women and men ranging in age from 18 to 23. Each focus group consisted of two to four people in a group. There were in total twenty participants (twelve women and eight men). They were high school and university students and were both heterosexual and homosexual. The project illustrates the discursive analyses of the actual audiotaped discussions that emerged during the sessions. The most common discourses in which the young people located themselves were: love and sex discourse, relationships, family and career and being gay or being straight. Discursive analyses of the speakers' talk showed how people negotiated their selves with others. Their self-constructions were organized strategically in the situated contexts at hand. These constructions were multiple and varied depending on the rhetorical context and function of talk. People variously drew on contradictory themes in order to make themselves socially accountable to the researcher and their peers. The project also addressed the social, moral and political implications of the discursive turn to identity.

description: Models of stellar structure and evolution can be constrained by measuring accurate parameters of detached eclipsing binaries in open clusters. Multiple binary stars provide the means to determine helium abundances in these old stellar systems, and in turn, to improve estimates of their age. In the first paper of this series, we demonstrated how measurements of multiple eclipsing binaries in the old open cluster NGC6791 sets tighter constraints on the properties of stellar models than has previously been possible, thereby potentially improving both the accuracy and precision of the cluster age. Here we add additional constraints and perform an extensive model comparison to determine the best estimates of the cluster age and helium content, employing as many observational constraints as possible. We improve our photometry and correct empirically for differential reddening effects. We then perform an extensive comparison of the CMDs and eclipsing binary measurements to Victoria and DSEP isochrones to estimate cluster parameters. We also reanalyse a spectrum of the star 2-17 to improve [Fe/H] constraints. We find a best estimate of the age of ~8.3 Gyr while demonstrating that remaining age uncertainty is dominated by uncertainties in the CNO abundances. The helium mass fraction is well constrained at Y = 0.30 \pm 0.01 resulting in dY/dZ ~ 1.4 assuming that such a relation exists. During the analysis we firmly identify blue straggler stars, including the star 2-17, and find indications for the presence of their evolved counterparts. Our analysis supports the RGB mass-loss found from asteroseismology and we determine precisely the absolute mass of stars on the lower RGB, 1.15\pm0.02Msun. This will be an important consistency check for the detailed asteroseismology of cluster stars.

description: "Eppingen ist der Höhepunkt jeder Fachwerkfahrt im Kraichgau." So urteilt der anerkannte Fachwerkkenner, Prof. Dr.-Ing. Erwin Huxhold, in seinem Buch über die "Fachwerkbauten im Kraichgau". Die Eppinger Altstadt hat sich in den vergangenen 50 Jahren zu einem echten Schmuckkästchen entwickelt. Im neuen "Kraichgau- Kultur & Naturführer" bezeichnet Dieter Balle sogar die Eppinger Altstadt als eines "der schönsten mittelalterlichen Fachwerk- Ensembles Deutschlands". Ein Attribut, das uns Eppinger stolz macht. Einen ganz entscheidenten Anteil an dieser Entwicklung hatte unser Ehrenvorsitzender Edmund Kiehnle. Schon früh erkannte er den Wert und die Bedeutung der Eppinger Altstadt. So wurden auf seine Initiative hin seit 1949 über 100 Fachwerkhäuser freigelegt und saniert. Edmund Kiehnle hat sich dabei als Stadtbaumeister und Kreisdenkmalpfleger, als Architekt und Hausforscher, als Stadtarchivar, Gründer und Leiter des Museums für seine Heimatstadt eng In dem nun vorliegenden 8. Band unserer Schriftenreihe "Rund um den Ottilienberg" haben wir die große Fülle der Veröffentlichungen von Edmund Kiehnle aus den vergangenen 53 Jahren gesammelt. Die abgedruckten Aufsätze, von denen viele in den regionalen Zeitungen erstmals erschienen sind, lassen seine unablässigen Bemühungen um die Fachwerkfreilegungen, den Denkmalschutz und die Erforschung der Stadtgeschichte erkennen. Aufgrund der Konzeption sind für einzelne Fachwerkhäuser ganz bewusst zwei, gelegentlich sogar drei Beiträge aus verschiedenen Jahrzehnten aufgenommen worden. Sie ermöglichen, nicht nur Fortschritte bei der Freilegung des Fachwerks und den Wandel auch der Denkmalschutzkonzeption zu erkennen, sie zeigen auch, dass die Stadtgeschichtsforschung in diesen Jahrzehnten immer wieder neue Erkenntnisse hervorgebracht hat, die in der Regel durch Anmerkungen sichtbar gemacht wurden. Entstanden ist ein wertvolles Quellen- und Arbeitsbuch zur Regionalgeschichte, ein Nachschlagewerk über die Eppinger Fachwerkhäuser, aber auch ein interessanter Führer durch unsere Eppinger Altstadt. Viele Fotos und Zeichnungen von Edmund Kiehnle veranschaulichen deutlich die Entwicklung unserer Altstadt im letzten halben Jahrhundert.agiert und verdient gemacht.

description: A theory is presented for the onset of shear thickening in colloidal suspensions of particles, stabilized by an electrostatic repulsion. Based on an activation model a critical shear stress can be derived for the onset of shear thickening in dense suspensions for a constant potential and a constant charge approach of the spheres. Unlike previous models the total interaction potential is taken into account (sum of attraction and repulsion). The critical shear stress is related to the maximum of the total interaction potential scaled by the free volume per particle. A comparison with experimental investigations shows the applicability of the theory.
