Climate is a paradigm of a complex system. Analysing climate data is an exciting challenge, which is increased by non-normal distributional shape, serial dependence, uneven spacing and timescale uncertainties. This book presents bootstrap resampling as a computing-intensive method able to meet the challenge. It shows the bootstrap to perform reliably in the most important statistical estimation techniques: regression, spectral analysis, extreme values and correlation.This book is written for climatologists and applied statisticians. It explains step by step the bootstrap algorithms (including novel adaptions) and methods for confidence interval construction. It tests the accuracy of the algorithms by means of Monte Carlo experiments. It analyses a large array of climate time series, giving a detailed account on the data and the associated climatological questions. This makes the book self-contained for graduate students and researchers. Climate is a paradigm of a complex system.

Master's Thesis from the year 2011 in the subject Nature Protection, Landscape Conservation, grade: 1,3, Christian-Albrechts-University of Kiel (Institut für Natur- und Ressourcenschutz Abteilung Landschaftsökologie), course: Environmental Management, Umweltmanagement, language: English, abstract: The stock of the European brown hare (Lepus europaeus PALLAS, 1778) is declining since decades, in Germany as well as in other European countries.At the same time,the occurrence of European brown hares is a new phenomenon in urban areas. Hence,Lichtenberg, a city district of Berlin, the capital of Germany, even assumed a special responsibility for its new inhabitants.Whereas a method for the quantification of this common game species in agricultural areas already exists, a new quantification method for city habitats is required in order to overcome several limitations. The aim of this master thesis is to deliver a suitable quantification method for Lepus europaeus, which can be applied by nature conservation authorities in future.By means of a strong LED torchlight and a bike, 153.74 ha of green area, which is usually scattered between residential buildings, were investigated in the style of the previous "spotlight taxation". These investigated areas belong to five different tracks. Each trackwas investigated three times in the late evening hours in the spring period from 8th of March until the 25th of April 2011. Within this time 37 sightings of hares have been made. Summing up the five maximum values from each of the 3 countings, one could assume that at least 17 hares live within the illuminated area. Considering the territorial behaviour, even a minimum number of 19 hares is probable. If additionally only suitable tracks are taken into account, a density of 16.98 hares/100 ha can be calculated - asurprisingly high value compared to the results of spotlight counting in surrounding federal states, where the agricultural landscape, and therefore the natural habitat of Lepus europaeus, is more prevalent. However, a direct comparison to the hare densities inthe open landscape, which are obtained by means of different methods is incorrect. Nevertheless, if the proposed aspects for a future implementation will be taken into consideration in the long run, it is a realisable method for the quantification of urban hare populations. Moreover, the interested public can participate on this scientific approach as well. Then, cost reduction and the rising awareness for wild animals in the public are positive side-effects.

Legal argumentation consists in the interpretation of texts. Therefore, it has a natural connection to the philosophy of language. Central issues of this connection, however, lack a clear answer. For instance, how much freedom do judges have in applying the law? How are the literal and the purposive approaches related to one another? How can we distinguish between applying the law and making the law?This book provides answers by means of a complex and detailed theory of literal meaning. A new legal method is introduced, namely the further development of the law. It is so far unknown in Anglo-American jurisprudence, but it is shown that this new method helps in solving some of the most crucial puzzles in jurisprudence.At its centre the book addresses legal indeterminism and refutes linguistic-philosophical reasons for indeterminacy. It spells out the normative character of interpretation as emphasized by Raz and, with the help of Robert Brandom's normative pragmatics, it is shown that the relativism of interpretation from a normative perspective does not at all justify scepticism. On the contrary, it supports the claim that legal argumentation can be objective, and maintains that statements on the meaning of a statute can be right or wrong, and take on inter-subjective validity accordingly. This book breaks new ground in transferring Brandom's philosophy to legal theoretical problems and presents an original and exciting analysis of the semantic argument in legal argumentation. It was the recipient of the European Award for Legal Theory in 2002.'This book represents, on the one hand, a reception of Robert Brandom's important theory including applications of this theory in the field of legal philosophy and, on the other, an exploration of the limits of an appeal in legal interpretation to the text. The enquiry thereby impinges upon the central juridico-philosophical themes of meaning, objectivity, and normativity. The author's work counts as a significant contribution to analytical jurisprudence and is deserving of a wide readership.' Robert Alexy, Professor for Public Law and Legal Philosophy, Kiel.'Klatt focuses on a very profound theory of concept formation and uses this theory in a creative way to solve classical problems of legal argumentation.'

The Kernel Method of Test Equating
284,00 CHF *
ggf. zzgl. Versand

Kernel Equating (KE) is a powerful, modern and unified approach to test equating. It is based on a flexible family of equipercentile-like equating functions and contains the linear equating function as a special case. Any equipercentile equating method has five steps or parts. They are: 1) pre-smoothing; 2) estimation of the score-probabilities on the target population; 3) continuization; 4) computing and diagnosing the equating function; 5) computing the standard error of equating and related accuracy measures. KE brings these steps together in an organized whole rather than treating them as disparate problems. KE exploits pre-smoothing by fitting log-linear models to score data, and incorporates it into step 5) above. KE provides new tools for diagnosing a given equating function, and for comparing two or more equating functions in order to choose between them. In this book, KE is applied to the four major equating designs and to both Chain Equating and Post-Stratification Equating for the Non-Equivalent groups with Anchor Test Design. This book will be an important reference for several groups: (a) Statisticians and others interested in the theory behind equating methods and the use of model-based statistical methods for data smoothing in applied work; (b) Practitioners who need to equate tests—including those with these responsibilities in testing companies, state testing agencies and school districts; and (c) Instructors in psychometric and measurement programs. The authors assume some familiarity with linear and equipercentile test equating, and with matrix algebra.

Digital Enhancement of EEG/MEG Signals
57,90 CHF *
ggf. zzgl. Versand

Electroencephalography (EEG) and Magnetoencephalography (MEG) recordings are commonly used for analyzing the brain. However, in most cases, the recordings not only contain brain waves, but also artifacts of physiological (ocular, muscle, ECG artifacts) or technical (electrode popping, power-line) origins, and noise from different sources. The main aim of the work described in this thesis is the noise reduction and artifact suppression from EEG and MEG signals. Different techniques for artifact suppression have been used: A Low-Pass Filter (LPF), an instantaneous Independent Component Analysis (ICA) algorithm, a combination of ICA and LPF, a combination of ICA and State-Space Modeling (SSM), a combination of ICA and Wiener filters, and a hybrid filter (i.e., a filter that works in the time- and frequency-domains). These techniques have been tested only offline in the present work. Additionally, two artifact suppression methods that could work either offline or in real-time have been tested in real-time. The first one is a recent approach used for signal enhancement, called Empirical Mode Decomposition (EMD). This method is employed in this work for denoising, for detrending, and for suppressing the muscle artifacts from EEG signals. The second method is an algorithm here called Classification-based Signal Enhancement (CBSE). It was also used to suppress muscle artifacts in EEG signals, in real-time, using Wiener filters for signal enhancement. In order to use any artifact suppression technique, the artifacts to be removed have to be previously identified. If the artifact suppression is done offline, the detection can be carried out by visual inspection of the data by an expert, or in an automatic way. On the other hand, if the suppression of artifacts has to be done in real-time, the artifacts have to be detected automatically. A detection technique is proposed in the present work. First, different features are extracted from the independent components, and then a threshold-based classification is performed to determine which components are contaminated, what kind of artifacts they contain, and how the suppression of the artifacts is realized. This method was tested in an offline manner in this thesis. The effectiveness of the proposed artifact suppression techniques was demonstrated by application to either “semi-simulated” EEG signals artificially contaminated with artifacts, or to real EEG/MEG data from a healthy subject or a patient suffering from epilepsy (inherently contaminated with different kinds of artifacts). It is shown by visual inspection and in a quantitative manner that, after applying the different techniques, the EEG/MEG signals are enhanced. To reduce the noise, an equalizer and a Wiener filter have been used. The signals employed for this purpose correspond to those from the newly developed magnetoelectric (ME) sensors at Kiel University.
