Coagulation is treated as cluster–cluster agglomeration along the line connecting the center of mass of both agglomerates and is implemented using a Monte Carlo algorithm. Sintering is modeled as successive overlapping of spheres which cause reduction in the surface area based on a rate law for surface reduction. Surface growth is modeled as an increase in primary particle diameter, e.g. as a result of surface reactions. The evolved aggregates are analyzed by calculating their fractal dimension, radius of gyration, mobility diameter and mobility shape factor. It is found that the aggregates structure tends to be more compact when introducing the surface growth in shorter time comparing to the coagulation-sintering step only. Fractal dimension and the mobility shape factor of the resulting aggregates are correlated to an effective dimensionless time that combines the characteristic times of these three fundamental mechanisms. It is shown that the mobility diameter in the free molecular regime is not proportional to the radius of gyration. A power law relation that correlates the aggregates projected area and the equivalent number of primary particles is found to be in a very good agreement with estimates published in literature.}}, author = {{Al Zaitone, Belal and Schmid, Hans-Joachim and Peukert, Wolfgang}}, issn = {{0021-8502}}, journal = {{Journal of Aerosol Science}}, number = {{11}}, pages = {{950--964}}, title = {{{Simulation of structure and mobility of aggregates formed by simultaneous coagulation, sintering and surface growth}}}, doi = {{10.1016/j.jaerosci.2009.08.007}}, volume = {{40}}, year = {{2009}}, } @article{26139, abstract = {{The study presents first experimental results of the transfer of magnetite nanoparticles from an aqueous to a second non-miscible non-aqueous liquid phase. The transfer is based on the adsorption of macromolecular surfactants onto the particle surface at the liquid–liquid interface. For a successful direct phase transfer, it is essential to have cations, like ammonium ions, present in the aqueous phase as well as a threshold concentration of surfactant in the organic liquid phase. While penetrating the liquid–liquid interface, the particles are covered with the surfactant and therefore a partial de-agglomeration is initiated. Based on literature and experimental data a mechanism of surfactant adsorption is proposed. The competing adsorption of the surfactant molecules at the liquid–liquid interface leads to the formation of emulsions and therefore to a hindrance for particles passing the interface.

For a fundamental understanding of particle sintering characteristics, the neck growth kinetics in agglomerate chains and in doublets consisting of differently sized primary particles is investigated. Results show that different sintering contacts in agglomerates even during the first stages are not completely independent from each other, even though differences are small. The neck growth kinetics of differently sized primary particles is determined by the smaller one up to a size difference by a factor of approximately 2, whereas for larger size differences, the kinetics becomes faster. In particular, the agglomerate sintering kinetics is investigated for particle chains of different lengths and for different particle morphologies each having ten primary particles and nine initial sintering contacts. For agglomerate chains, the kinetics approximately can be normalized by using the radius of the fully coalesced sphere. In general, different agglomerate morphologies show equal kinetics during the first sintering stages, whereas during advanced stages, compact morphologies show significantly faster sintering progress than more open morphologies. Hence, the overall kinetics cannot be described by simply using constant morphology correction factors such as fractal dimension or mean coordination number which are used in common sintering models. However, for the first stages of viscous-flow agglomerate sintering, which are the most important for many particle processes, a sintering equation is presented.

Agreement between the RQ and WR was tested by classification into consumers and non-consumers (kappa coefficients, κ), by the children’s ability to estimate the exact beverage and total volume consumed (Wilcoxon signed-rank test, Spearman rank correlation), and by ranking children according to reported beverage volumes.ResultsThe RQ and WR showed a good level of agreement for classifying participants into consumers and non-consumers of the single beverage categories (κ values between 0·78 and 0·94). Correlation coefficients for the volume of the single categories ranged between 0·81 and 0·91. The total beverage volume was overestimated in the RQ, on average, by 114 ml (P = 0·015). Agreement in ranking into tertiles by beverage volume was moderate to good for juice/soft drinks (κ = 0·44), milk (κ = 0·57) and water (κ = 0·70), but fair for the total beverage volume (κ = 0·23).ConclusionsOur self-completion 24 h RQ could estimate the consumption of several beverage categories among young children at the group level, but quantification of total beverage volume was flawed.}}, author = {{Muckelbauer, Rebecca and Libuda, Lars and Kersting, Mathilde}}, issn = {{1368-9800}}, journal = {{Public Health Nutrition}}, pages = {{187--195}}, title = {{{Relative validity of a self-completion 24 h recall questionnaire to assess beverage consumption among schoolchildren aged 7 to 9 years}}}, doi = {{10.1017/s1368980009990759}}, year = {{2009}}, } @article{27133, author = {{Cheng, G. and Karaolis-Danckert, N. and Libuda, Lars and Bolzenius, K. and Remer, T. and Buyken, Anette E.}}, issn = {{0002-9262}}, journal = {{American Journal of Epidemiology}}, pages = {{667--677}}, title = {{{Relation of Dietary Glycemic Index, Glycemic Load, and Fiber and Whole-Grain Intakes During Puberty to the Concurrent Development of Percent Body Fat and Body Mass Index}}}, doi = {{10.1093/aje/kwn375}}, year = {{2009}}, } @article{27134, author = {{Muckelbauer, R. and Libuda, Lars and Clausen, K. and Kersting, M.}}, issn = {{0305-1862}}, journal = {{Child: Care, Health and Development}}, pages = {{851--857}}, title = {{{Long-term process evaluation of a school-based programme for overweight prevention}}}, doi = {{10.1111/j.1365-2214.2009.00993.x}}, year = {{2009}}, } @article{27135, author = {{Muckelbauer, Rebecca and Libuda, Lars and Clausen, Kerstin and Reinehr, Thomas and Kersting, Mathilde}}, issn = {{1662-4033}}, journal = {{Obesity Facts}}, pages = {{282--285}}, title = {{{A Simple Dietary Intervention in the School Setting Decreased Incidence of Overweight in Children}}}, doi = {{10.1159/000229783}}, year = {{2009}}, } @article{27136, author = {{Muckelbauer, R. and Libuda, Lars and Clausen, K. and Toschke, A.

In addition, a validation study applying 24 h dietary recalls was performed.DesignUsing the variance-based Max_r method, a list of eighty-two foods was compiled from data obtained by 3 d weighed dietary records. The foods were used to design an FFQ, the comprehensibility of which was evaluated in a feasibility study. In addition, the FFQ was validated in a subset of 101 children from the German Infant Nutritional Intervention Study (GINI PLUS) against one 24 h dietary recall.ResultsThe feasibility study attested a good acceptance of the FFQ. Mean intake of foods compared well between the FFQ and the 24 h dietary recall, although intake data generated from the FFQ tended to be higher. This difference became less apparent at the nutrient level, although the estimated average consumption of arachidonic acid and EPA using the FFQ still exceeded values recorded with the 24 h recall method by 45 % and 29 %, respectively.ConclusionsOn the basis of the systematic selection process of the food list, the established practicability of the FFQ and the overall plausibility of the results, the use of this FFQ is justified in future epidemiological studies.}}, author = {{Stiegler, Petra and Sausenthaler, Stefanie and Buyken, Anette and Rzehak, Peter and Czech, Daniel and Linseisen, Jakob and Kroke, Anja and Gedrich, Kurt and Robertson, Claire and Heinrich, Joachim}}, issn = {{1368-9800}}, journal = {{Public Health Nutrition}}, pages = {{38--46}}, title = {{{A new FFQ designed to measure the intake of fatty acids and antioxidants in children}}}, doi = {{10.1017/s1368980009005813}}, year = {{2009}}, } @article{27722, author = {{Shi, Lijie and Berkemeyer, Shoma and Buyken, Anette and Maser-Gluth, Christiane and Remer, Thomas}}, issn = {{0026-0495}}, journal = {{Metabolism}}, pages = {{134--139}}, title = {{{Glucocorticoids and body fat associated with renal uric acid and oxalate, but not calcium excretion, in healthy children}}}, doi = {{10.1016/j.metabol.2009.06.027}}, year = {{2009}}, } @article{27751, author = {{Buyken, Anette and Günther, Anke LB and Barclay, Alan and Brand-Miller, Jennie and Schulze, Matthias B}}, issn = {{0002-9165}}, journal = {{The American Journal of Clinical Nutrition}}, pages = {{243--244}}, title = {{{Glycemic index in overweight development: distinguishing limited evidence from limits in evidence}}}, doi = {{10.3945/ajcn.2009.27742}}, year = {{2009}}, } @inproceedings{2783, author = {{Kundisch, Dennis and Mittal, N. and Nault, B.}}, booktitle = {{10th Workshop on Information Systems and Economics (WISE)}}, location = {{Phoenix, USA}}, title = {{{IT Productivity and Aggregation using Income Accounting}}}, year = {{2009}}, } @inproceedings{2784, author = {{Kundisch, Dennis and Zorzi, R.}}, booktitle = {{Proceedings of the 15th Amercas Conference on Information Systems (AMCIS)}}, location = {{San Francisco, USA}}, pages = {{259--270}}, publisher = {{Springer}}, title = {{{Enhancing the Quality of Financial Advice with Web 2.0 - An Approach considering Social Capital in the private Asset Allocation}}}, year = {{2009}}, } @inproceedings{2785, author = {{Kundisch, Dennis and Klein, C.}}, booktitle = {{International Federation of Classification Societies 2009 Conference}}, location = {{Dresden, Germany}}, title = {{{An Evaluation Framework for Tracker Certificates during the Financial Crisis and beyond}}}, year = {{2009}}, } @inbook{2787, author = {{Dorfleitner, G. and Klein, C. and Kundisch, Dennis}}, booktitle = {{Monetary Growth: Trends, Impacts and Policies}}, publisher = {{Nova Science Publishers}}, title = {{{Technical Analysis as a Method of Risk Management}}}, year = {{2009}}, } @article{27879, author = {{Eickelmann, Birgit}}, journal = {{Journal for Educational Research Online}}, number = {{1}}, pages = {{257--261}}, title = {{{Rezension zu L.J.

While being a strongly concurrent distributed system, its embedded aspects with severe resource limitations and the wireless communication requires a fusion of technologies and methodologies from very different fields. As WSNs are deployed in remote locations for long-term unattended operation, assurance of correct functioning of the system is of prime concern. Thus, the design and development of WSNs requires specialized tools to allow for testing and debugging the system. To this end, we present a framework for analyzing and checking WSNs based on collected events during system operation. It allows for abstracting from the event trace by means of behavioral queries and uses assertions for checking the accordance of an execution to its specification. The framework is independent from WSN test platforms, applications and logging semantics and thus generally applicable for analyzing event logs of WSN test executions. }}, author = {{Woehrle, Matthias and Plessl, Christian and Thiele, Lothar}}, keywords = {{Rupeas, DSL, WSN, testing}}, title = {{{Rupeas: Ruby Powered Event Analysis DSL}}}, year = {{2009}}, } @article{2354, author = {{Brinkmann, André and Eschweiler, Dominic}}, journal = {{Journal of Supercomputing}}, pages = {{35:1--35:10}}, publisher = {{ACM}}, title = {{{A Microdriver Architecture for Error Correcting Codes inside the Linux Kernel}}}, doi = {{10.1145/1654059.1654095}}, year = {{2009}}, } @inbook{23744, abstract = {{In a Stackelberg pricing game a leader aims to set prices on a subset of a given collection of items, such as to maximize her revenue from a follower purchasing a feasible subset of the items. We focus on the case of computationally bounded followers who cannot optimize exactly over the range of all feasible subsets, but apply some publicly known algorithm to determine the set of items to purchase. This corresponds to general multi-dimensional pricing assuming that consumers cannot optimize over the full domain of their valuation functions but still aim to act rationally to the best of their ability. We consider two versions of this novel type of Stackelberg pricing games. Assuming that items are weighted objects and the follower seeks to purchase a min-cost selection of objects of some minimum weight (the Min-Knapsack problem) and uses a simple greedy 2-approximate algorithm, we show how an extension of the known single-price algorithm can be used to derive a polynomial-time (2 + ε)-approximation algorithm for the leader’s revenue maximization problem based on so-called near-uniform price assignments. We also prove the problem to be strongly NP-hard. Considering the case that items are subsets of some ground set which the follower seeks to cover (the Set-Cover problem) via a standard primal-dual approach, we prove that near-uniform price assignments fail to yield a good approximation guarantee. However, in the special case of elements with frequency 2 (the Vertex-Cover problem) it turns out that exact revenue maximization can be done in polynomial-time. This stands in sharp contrast to the fact that revenue maximization becomes APX-hard already for elements with frequency 3.}}, author = {{Briest, Patrick and Hoefer, Martin and Gualà, Luciano and Ventre, Carmine}}, booktitle = {{Lecture Notes in Computer Science}}, issn = {{0302-9743}}, title = {{{On Stackelberg Pricing with Computationally Bounded Consumers}}}, doi = {{10.1007/978-3-642-10841-9_6}}, year = {{2009}}, } @misc{23771, author = {{Fechner, Sabine and Treagust, David F.}}, booktitle = {{International Journal of Science Education}}, number = {{4}}, pages = {{596--601}}, title = {{{Making it relevant: Context-based learning of science [Book review]}}}, volume = {{31}}, year = {{2009}}, } @inproceedings{18138, abstract = {{Modern companies are nowadays confronted with an increasing demand of multiple products, where they need to perform more flexible every day.

This paper presents implemented concepts for an innovative user support in his tasks of verification and validation of simulation models during the execution of a simulation run.

We deduce the EXISTENCE of an O(m^2/n^2) space data structure for S that, given p and time O(log n), allows to approximate the ratio of occluded segments up to arbitrary constant absolute error; here m denotes the size of the Visibility Graph--which may be quadratic, but typically is just linear in the size n of the scene S. On the other hand, we present a data structure CONSTRUCTIBLE in O(n*log(n)+m^2*polylog(n)/k) preprocessing time and space with similar approximation properties and query time O(k*polylog n), where k
