The resulted powders of nanocrystals (NCs) were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and atomic force microscopy (AFM) measurements. The obtained results confirm the presence of the both of oxides nanopowders produced during chemical precipitation using microwave irradiation. A strong emission under UV excitation is obtained from the prepared CuO and Co3O4 nanoparticles. The results show that the nanoparticles have high dispersion and narrow size distribution. The line scans of atomic force microscopy (AFM) images of the nanocrystals (NCs) sprayed on GaAs substrates confirm the results of both X-ray diffraction and transmission electron microscopy. Furthermore, vibrational studies have been carried out using Raman spectroscopic technique. Specific Raman peaks have been observed in the CuO and Co3O4 nanostructures, and the full width at half maximum (FWHM) of the peaks indicates a small particle size of the nanocrystals."}],"_id":"47940","publisher":"Hindawi Limited","page":"714853","volume":2013,"user_id":"22501","status":"public","oa":"1","citation":{"ama":"Rashad M, Rüsing M, Berth G, Lischka K, Pawlis A.

Since typically the solution set of such multi-objective optimization problems forms a manifold which cannot be computed analytically, one is in many cases interested in a suitable finite size approximation of this set. One widely used approach is to find a representative set that maximizes the dominated hypervolume that is defined by the images in objective space of these solutions and a given reference point.\r\n\r\nIn this paper, we propose a new point-wise iterative search procedure, Hypervolume Directed Search (HVDS), that aims to increase the hypervolume of a given point in an archive for bi-objective unconstrained optimization problems. We present the HVDS both as a standalone algorithm and as a local searcher within a specialized evolutionary algorithm. Numerical results confirm the strength of the novel approach."}],"publication":"EVOLVE — A Bridge between Probability, Set Oriented Numerics, and Evolutionary Computation IV","department":[{"_id":"34"},{"_id":"819"}],"type":"book_chapter","date_created":"2023-08-04T15:37:00Z","status":"public","volume":227,"editor":[{"full_name":"Emmerich, M","first_name":"M","last_name":"Emmerich"},{"full_name":"Deutz, A","first_name":"A","last_name":"Deutz"},{"full_name":"Schuetze, O","first_name":"O","last_name":"Schuetze"},{"last_name":"Bäck","first_name":"T","full_name":"Bäck, T"},{"first_name":"A","last_name":"Tantar","full_name":"Tantar, A"},{"first_name":"PD","last_name":"Moral","full_name":"Moral, PD"},{"full_name":"Legrand, P","first_name":"P","last_name":"Legrand"},{"full_name":"Bouvry, P","first_name":"P","last_name":"Bouvry"},{"full_name":"Coello, CA","last_name":"Coello","first_name":"CA"}],"user_id":"15504","publisher":"Springer International Publishing","_id":"46385","page":"189–205","citation":{"mla":"Sosa, Hernández V., et al. “The Directed Search Method for Pareto Front Approximations with Maximum Dominated Hypervolume.” <i>EVOLVE — A Bridge between Probability, Set Oriented Numerics, and Evolutionary Computation IV</i>, edited by M Emmerich et al., vol. 227, Springer International Publishing, 2013, pp. 189–205, doi:<a href=\"https://doi.org/10.1007/978-3-319-01128-8_13\">10.1007/978-3-319-01128-8_13</a>.","ama":"Sosa HV, Schütze O, Rudolph G, Trautmann H.

Nevertheless, these methods still suffer the drawback that many function evaluations are required to obtain a suitable representation of the solution set. The aim of this study is to present the Directed Search (DS) Method as local searcher within global indicator based optimization algorithms. For this, we will present the DS in the context of hypervolume maximization leading to both a new local search algorithm and a new memetic algorithm. Further, we will present first attempts to adapt the DS to a class of parameter dependent problems.","lang":"eng"}],"place":"New York, NY, USA","date_created":"2023-08-04T15:45:26Z","department":[{"_id":"34"},{"_id":"819"}],"type":"conference"},{"date_updated":"2023-10-16T13:45:34Z","author":[{"first_name":"C","last_name":"Dominguez-Medina","full_name":"Dominguez-Medina, C"},{"full_name":"Rudolph, G","first_name":"G","last_name":"Rudolph"},{"full_name":"Schütze, O","first_name":"O","last_name":"Schütze"},{"full_name":"Trautmann, Heike","orcid":"0000-0002-9788-8282","last_name":"Trautmann","first_name":"Heike","id":"100740"}],"title":"Evenly spaced Pareto fronts of quad-objective problems using PSA partitioning technique","year":"2013","status":"public","doi":"https://doi.org/10.1109/CEC.2013.6557960","user_id":"15504","_id":"46387","language":[{"iso":"eng"}],"page":"3190–3197","abstract":[{"lang":"eng","text":"Here we address the problem of computing finite size Hausdorff approximations of the Pareto front of four-objective optimization problems by means of evolutionary computing.

Desirability functions (DFs) allow the preferences of the decision maker to be specified in an intuitive way. Recently, it has been shown for continuous optimization problems that an a priori transformation of the objectives by means of DFs can be used to focus the search of a hypervolume-based evolutionary algorithm on the desired part of the front. In many-objective optimization, however, the computational complexity of the hypervolume can become a crucial part. Thus, an alternative to this approach will be presented in this paper. The new algorithm operates in the untransformed objective space, but the desirability index (DI), that is, a DF-based scalarization, will be used as the second-level selection criterion in the non-dominated sorting. The diversity and uniform distribution of the resulting approximation are ensured by the use of an external archive. In the experiments, different preferences are specified as DFs, and their effects are investigated. It is shown that trade-off solutions are generated in the desired regions of the Pareto-optimal front and with a density adaptive to the DI. The efficiency of the approach with respect to increasing objective space dimension is also analysed using scalable test functions. The convergence speed is superior to other set-based and preference-based evolutionary multiobjective algorithms while the approach is of low computational complexity due to cheap DI evaluations.

In order to understand the behavior and the approximations preferred by these indicators and algorithms, a comprehensive knowledge of the indicator’s properties is required. Whereas this knowledge is available for the HV, we presented a first approach in this direction for the R2 indicator just recently. In this paper, we build upon this knowledge and enhance the considerations with respect to the integration of preferences into the R2 indicator. More specifically, we analyze the effect of the reference point, the domain of the weights, and the distribution of weight vectors on the optimization of $\\mu$ solutions with respect to the R2 indicator.

The relative position information is gathered from inertial smartphone sensors using a step detection and an orientation estimate. Our map data is hosted on a server employing a map renderer and a SQL database. The database includes a complete multilevel office building, within which the user can navigate. During navigation, the client retrieves the position estimate from the server, together with the corresponding map tiles to visualize the user's position on the smartphone display.","lang":"eng"}],"publication":"Positioning Navigation and Communication (WPNC), 2013 10th Workshop on"},{"oa":"1","department":[{"_id":"54"}],"type":"conference","date_created":"2019-07-12T05:28:50Z","abstract":[{"lang":"eng","text":"In this paper we present a modified hidden Markov model (HMM) for the fusion of received signal strength index (RSSI) information of WiFi access points and relative position information which is obtained from the inertial sensors of a smartphone for indoor positioning. Since the states of the HMM represent the potential user locations, their number determines the quantization error introduced by discretizing the allowable user positions through the use of the HMM. To reduce this quantization error we introduce â??pseudoâ?? states, whose emission probability, which models the RSSI measurements at this location, is synthesized from those of the neighboring states of which a Gaussian emission probability has been estimated during the training phase. The experimental results demonstrate the effectiveness of this approach. By introducing on average two pseudo states per original HMM state the positioning error could be significantly reduced without increasing the training effort."}],"related_material":{"link":[{"url":"https://groups.uni-paderborn.de/nt/pubs/2013/HoScDrTrHa2013_Poster.pdf","relation":"supplementary_material","description":"Poster"}]},"quality_controlled":"1","citation":{"ama":"Hoang MK, Schmalenstroeer J, Drueke C, Tran Vu DH, Haeb-Umbach R.
