However, only a few studies have analysed the prospective relationship between dietary patterns and weight status in children. The aims of the present study were to identify dietary patterns at the beginning of and during the primary school period and to examine their relevance to the development of body composition. Nutritional and anthropometric data from 371 participants of the Dortmund Nutritional and Longitudinally Designed (DONALD) Study at the beginning (ages 6 and 7 years) and end (ages 10 and 11 years) of the primary school period were used. Principal component analyses (PCA) were conducted to identify dietary patterns, which were regressed on changes in BMI and fat mass index (FMI) between ages 6 and 7 years and ages 10 and 11 years. Reduced rank regression (RRR) was used to directly extract patterns explaining variation in changes in BMI and FMI between ages 6 and 7 years and ages 10 and 11 years. PCA yielded interpretable patterns of dietary changes at the beginning of and during the primary school period, which were not related to changes in body composition. Conversely, RRR allowed identifying predictive patterns: higher baseline intakes of white bread and lower baseline intakes of whole-grain products as well as increases in the consumption of savoury snacks, sausages and cheese during primary school years independently predicted increases in BMI and FMI during the primary school period. In conclusion, selection of unfavourable carbohydrate sources at the beginning of the primary school period and increases in the consumption of processed savoury foods during primary school years may adversely affect the development of body composition during the course of primary school.</jats:p>","lang":"eng"}],"page":"1488-1498","language":[{"iso":"eng"}],"_id":"26913","doi":"10.1017/s0007114513004017","user_id":"61597","year":"2014","status":"public","title":"Prospective relevance of dietary patterns at the beginning and during the course of primary school to the development of body composition","publication_identifier":{"issn":["0007-1145","1475-2662"]},"author":[{"last_name":"Diethelm","first_name":"Katharina","full_name":"Diethelm, Katharina"},{"last_name":"Günther","first_name":"Anke L.

Up to now, there is no emulation tool that is able to emulate large software-defined data center networks that consist of several thousand nodes. Mininet is the most common tool to emulate Software-Defined Networks of several hundred nodes. We extend Mininet to span an emulated network over several physical machines, making it possible to emulate networks of several thousand nodes on just a handful of physical machines. This enables us to emulate, e.g., large data center networks. To test this approach, we additionally introduce a traffic generator for data center traffic. Since there are no data center traffic traces publicly available we use the results of two recent traffic studies to create synthetic traffic. We show the design and discuss some challenges we had in building our traffic generator. As a showcase for our work we emulated a data center consisting of 3200 hosts on a cluster of only 12 physical machines. We show the resulting workloads and the trade-offs involved.","lang":"eng"}],"project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Subprojekt A2","_id":"6"},{"name":"SFB 901 - Project Area A","_id":"2"}],"publication":"Proceedings of the 2014 IFIP Networking Conference (Networking 2014)","file_date_updated":"2018-03-20T07:30:29Z","citation":{"mla":"Wette, Philip, et al. “MaxiNet: Distributed Emulation of Software-Defined Networks.” <i>Proceedings of the 2014 IFIP Networking Conference (Networking 2014)</i>, 2014, pp. 1–9, doi:<a href=\"https://doi.org/10.1109/IFIPNetworking.2014.6857078\">10.1109/IFIPNetworking.2014.6857078</a>.","ama":"Wette P, Dräxler M, Schwabe A, Wallaschek F, Zahraee MH, Karl H.

The selectionof lightpaths to be preempted relies on internal decisions of theRWA algorithm. Thus, if dedicated properties of the networktopology are required by the applications running on the network,these requirements have to be known to the RWA algorithm.We present a family of preemptive RWA algorithms for WDMnetworks. These algorithms have two distinguishing features: a)they can handle dynamic traffic by on-the-fly reconfiguration,and b) users can give feedback for reconfiguration decisions andthus influence the preemption decision of the RWA algorithm,leading to networks which adapt directly to application needs.This is different from traffic engineering where the network is(slowly) adapted to observed traffic patterns.Our algorithms handle various WDM network configurationsincluding networks consisting of heterogeneous WDM hardware.To this end, we are using the layered graph approach togetherwith a newly developed graph model that is used to determineconflicting lightpaths.","lang":"eng"}],"citation":{"apa":"Wette, P., &#38; Karl, H.

This paper investigates the placement and scaling of complex application architectures. An application is dynamically scaled to fit both the current demand situation and the currently available infrastructure resources. We compare two approaches: The first one is based on virtual network embedding. The second approach is a novel method called Template Embedding. It is based on a hierarchical 1-allocation hub flow problem and combines applica- tion scaling and embedding in one step. Extensive experiments on 43200 network configurations showed that Template Embedding outperforms virtual network embedding in all cases in three metrics: success rate, solution quality, and runtime. This positive result shows that template embedding is a promising approach for distributed cloud resource allocation."}],"project":[{"_id":"1","name":"SFB 901"},{"_id":"6","name":"SFB 901 - Subprojekt A2"},{"_id":"2","name":"SFB 901 - Project Area A"}],"publication":"Proceedings of 7th International Conference on Utility and Cloud Computing (UCC)","file_date_updated":"2018-03-20T07:23:02Z","citation":{"mla":"Keller, Matthias, et al. “Template Embedding: Using Application Architecture to Allocate Resources in Distributed Clouds.” <i>Proceedings of 7th International Conference on Utility and Cloud Computing (UCC)</i>, 2014, pp. 387--395, doi:<a href=\"https://doi.org/10.1109/UCC.2014.49\">10.1109/UCC.2014.49</a>.","ama":"Keller M, Robbert C, Karl H.

Normally, a set of chained network functions process network flows. Following the trend of virtualization of networks, virtualization of the network functions has also become a topic of interest. We define a model for formalizing the chaining of network functions using a context-free language. We process deployment requests and construct virtual network function graphs that can be mapped to the network. We describe the mapping as a Mixed Integer Quadratically Constrained Program (MIQCP) for finding the placement of the network functions and chaining them together considering the limited network resources and requirements of the functions. We have performed a Pareto set analysis to investigate the possible trade-offs between different optimization objectives.

To minimize the response time of requests, application servers closer to the user can hence be used to shorten network round trip times. However, this advantage is neutralized if the used data centre is highly loaded as the processing time of re- quests is important as well. We model the request response time as the network round trip time plus the processing time at a data centre.We present a capacitated facility location problem formal- ization where the processing time is modelled as the sojourn time of a queueing model. We discuss the Pareto trade-off between the number of used data centres and the resulting response time. For example, using fewer data centres could cut expenses but results in high utilization, high response time, and smaller revenues.Previous work presented a non-linear cost function. We prove its convexity and exploit this property in two ways: First, we transform the convex model into a linear model while controlling the maximum approximation error.

To reduce the energy consumption of RANs different techniques have been proposed. One of the most promising techniques is the use of a low-power sleep mode. However, a sleep mode can also reduce the performance. In this dissertation, I quantify how much energy can be conserved with a sleep mode and which negative effects it has on the performance of RANs. Additionally, I analyze how a sleep mode can be enabled more often and how the performance can be kept high. First, I quantify the effect of power-cycle durations on energy consumption and latency in an abstract queuing system. This results in a trade-off between energy consumption and latency for a single base station (BS). Second, I show that considering a network as a whole (instead of each BS individually) allows the energy consumption to be reduced even further. After these analyses, which are not specific for RANs, I study RANs for the rest of the dissertation. RANs need to both detect and execute the requests of users. Because detection and execution of requests have different requirements, I analyze them independently. I quantify how the number of active BSs can be reduced if the detection ranges of BSs are increased by cooperative transmissions. Next, I analyze how more BSs can be deactivated if the remaining active BSs cooperate to transmit data to the users. However, in addition to increasing the range, cooperative transmissions also radiate more power. This results in higher interference for other users which slows their transmissions down and, thus, increases energy consumption. Therefore, I describe how the radiated power of cooperative transmissions can be reduced if instantaneous channel knowledge is available. Because the implementation in real hardware is impractical for demonstration purposes, I show the results of a simulation that incorporates all effects I studied analytically earlier. In conclusion, I show that a sleep mode can reduce the energy consumption of RANs if applied correctly. To apply a sleep mode correctly, it is necessary to consider power-cycle durations, power profiles, and the interaction of BSs. When this knowledge is combined the energy consumption of RANs can be reduced with only a slight loss of performance. Because this results in a trade-off between energy consumption and performance, each RAN operator has to decide which trade-off is preferred.","lang":"eng"}],"project":[{"name":"SFB 901","_id":"1"},{"_id":"6","name":"SFB 901 - Subprojekt A2"},{"name":"SFB 901 - Project Area A","_id":"2"}],"file_date_updated":"2018-03-20T07:14:52Z","supervisor":[{"full_name":"Karl, Holger","last_name":"Karl","first_name":"Holger","id":"126"}],"citation":{"short":"M.
