A goodness-of-fit test for the random-effects distribution in mixed models
No full text© The Author(s) 2014. In this paper, we develop a simple diagnostic test for the random-effects distribution in mixed models. The test is based on the gradient function, a graphical tool proposed by Verbeke and Molenberghs to check the impact of assumptions about the random-effects distribution in mixed models on inferences. Inference is conducted through the bootstrap. The proposed test is easy to implement and applicable in a general class of mixed models. The operating characteristics of the test are evaluated in a simulation study, and the method is further illustrated using two real data analyses
Sepedon (Parasepedon) hispanica subsp. ruhengeriensis Verbeke 1950
No full textSepedon (Parasepedon) hispanica Loew ssp. ruhengeriensis Verbeke, 1950 Synonym by Verbeke (1964). (Figs 15, 17, 18, plate 9) References to figures: Verbeke 1950 (aedeagus, surstylus); Verbeke 1961 (surstylus). Knutson et al. 1967 (S. h. hispanica: egg; I, II, III instar cephalopharyngeal skeleton and posterior spiracular disc; II, III instar anterior spiracle, puparium). Holotype: ♂, RWANDA: Ruhengeri (sources Kiri), 1800–1825m, 31.viii.1934, (Mission G.F. de Witte) (MRAC). Seen by Knutson in 1978 in IRSNB, Cabinet 41, “Parc National Albert”, Box. 1. Verbeke, 1950 placed his S. ruhengeriensis and four other new species (S. lippensi, S. saegeri, S. simulans and S. uelensis) along with S. trichroocelis Speiser, 1910 in his “Groupe G (Groupe trichrooscelis)” of the subgenus Parasepedon. Verbeke (1963) placed S. parvipennis Steyskal, 1956 in this group, but that species was synonymized under S. saegeri in Verbeke (1963) and confirmed by Verbeke in litt. 1968 in his review of his MS of Knutson (1980). Knutson et al. (1967) noted “ Sepedon h. hispanica was described from one female collected in Andalusia (Loew, 1862). The species was apparently not seen by most European dipterists and its validity was in doubt until it was rediscovered by the senior author in Andalusia in 1964. Specimens were sent to Dr. J. Verbeke, who identified them as conspecific with the type specimen of Loew. Verbeke (1964) placed S. ruhengeriensis Verbeke, 1950 (described from tropical Africa) as a junior synonym of S. hispanica Loew 1862. The populations from Spain and Africa were considered subspecifically distinct and were given the trivial names of S. h. hispanica Loew and S. h. ruhengeriensis Verbeke, respectively. Keys to the six species were presented by Verbeke (1950, 1961). Verbeke (1961) placed the species in 3 “categories” (trichrooscelis + lippensi, saegeri + uelensis, and hispanica + simulans). Recent study of extensive material indicates that there are several additional species in this Group. In West Africa S. hispanica ruhengeriensis is most similar to S. trichrooscelis. In general, specimens of S. h. ruhengeriensis are larger than those of S. trichrooscelis and the femora are more distinctly reddened. The prosternum is usually more densely setose in S. hispanica ruhengeriensis than in S. trichrooscelis. The frons of S. hispanica ruhengeriensis is generally in part yellowish brown, but in S. trichrooscelis it is usually shiny black. NIGERIA: Zaria, Samaru, 1♂, 24.vii.1968 (USNM).

Consumer Interest and Marketing Potential of Information on Fish Labels
No full textFood labels are an important source of information to consumers. However, little scientific evidence is available on the type of information consumers seek on product labels and how consumers use food labels. The objective of this study is to assess consumers’ use of mandatory information cues and interest in potential information cues placed on fish labels, packages or shelves in five European countries. A cross-sectional consumer survey was carried out in November-December 2004 in five European countries: Belgium, Denmark, the Netherlands, Poland and Spain and a sample representative for age and region within each country has been obtained. Total sample size is 4,786. The results show a high use of on-label information cues; hence, labels were found as good, and potentially market effective sources of information. Consumers were most familiar with expiry date, price, species name and weight and they felt able to derive clear quality expectations from the information these cues convey. Consumers displayed the strongest interest in an additional information cues, such as safety guarantee and a quality mark for seafood. Cross-country differences in both use and interest in fish information cues were observed.consumer, fish, label, Consumer/Household Economics, Marketing,
Alignment and Ergativity in New Indo-Aryan Languages /
No full textThe book provides an overview of the alignment patterns found in modern Indo-Aryan languages. The analysis of the patterns of case marking and agreement leads to a balanced view on the concept of ergativity and evaluates its value for typological linguistics. The book offers an extensive discussion of previous approaches to ergativity. It analyzes four Indo-Aryan languages– Asamiya, Nepali, Rajasthani and Kashmiri– on the basis of text corpora. Examples from other Indo-Aryan languages are also adduced. The book is a thorough synchronic study of alignment patterns in Indo-Aryan languages.The book provides an overview of the alignment patterns found in modern Indo-Aryan languages.

However, the former could not be located, neither at the CABI (former CIBC), nor at the IRSN. Graham (1969: 530) stated that he had seen`the types’ but he may actually have examined only the specimens at the IRSN (Graham, apparently, rarely had access to type material deposited at the CIBC or in Delucchi’s private collection). As was the case for any other type material quoted for the CIBC by Delucchi, it seemed likely that it had either remained in his private collection or at the BMNH.</p> <p> There is now strong evidence that the specimens labelled as` Habrocytus verbekei’ in fact represent the missing part of the type series of <i>milleri</i>. Delucchi (pers. comm.) never intended to describe any other <i>Habrocytus</i> than <i>milleri</i>. Most likely he just failed to replace the labels when by Verbeke’s appearance as co-author a change in naming the species became necessary.

User interest prediction for tweets using semantic enrichment with DBpedia
No full textThis paper focuses on topic-based prediction of interest of individual users to posts in the context of Twitter. Two methods for enriching tweets using DBpedia for the purposes of classification are proposed. The first method incorporates entity linking and uses linked entities in a tweet to improve classification, whereas the second method aims to improve upon the first one by adding information derived from DBpedia about entities found using the first method. The two methods are evaluated with respect to tweet classification
Replication Data for: Bayesian Decision Algorithm for Symbol Diversity in a Three-Channel Redundant System Under Harsh Electromagnetic Disturbances
No full textThis dataset contains the data for our paper: Bayesian Decision Algorithm for Symbol Diversity in a Three-Channel Redundant System Under Harsh Electromagnetic Disturbances. The article presents an adaptive Bayesian decision algorithm designed to increase the certainty and reliability of the received data in challenging electromagnetic (EM) environments. The algorithm is designed to maintain a balance between the required level of certainty in the output and the system's availability. The method is validated on a symbol-diverse constellation transmitted through a triple modular redundant communication channel. A comparison with two different scenarios evaluates the algorithm's performance in terms of accuracy and availability. Furthermore, the comparative analysis highlights the algorithm's adaptability across various frequency combinations for EM disturbances
CoDEx-VFD: Controlled Disturbance Experiment - Variable Frequency Drive
No full text
The CoDEx-VFD dataset provides time-series current measurements from a three-phase Variable Frequency Drive (VFD) system subjected to controlled electromagnetic disturbances (EMD). This dataset is designed for benchmarking and comparing anomaly detection algorithms in the context of electromagnetic compatibility (EMC). The data was collected under controlled laboratory conditions, with varying levels of disturbance severity and frequency, providing a valuable resource for researchers developing and evaluating methods for EMI detection and mitigation in electronic systems.
The dataset comprises 100 CSV files, each representing a single measurement run with different anomaly scenarios. Measurements include two directly measured phase currents along with a binary label indicating the presence or absence of an injected disturbance at each time point. The sampling rate is 2.5 MHz, providing high temporal resolution for capturing transient EMI events. Key experimental parameters, including disturbance characteristics and equipment details, are documented in the accompanying README file.
