Intra-organizational networks (intranets) are increasingly being developed for information sharing and collaborative work in geographically dispersed organizations. In this paper we provide a framework to manage the resources in the intranets using the concepts of electronic commerce. Specifically, we propose the creation of an intranet Resource Management Application (iRMA) which manages the u...

Drawing on the boundary theory (Nippert-Eng, 1996a) and the concept of institutional framework according to Piszczek and Berg (2014), we explore in this paper the link between institutional settings and boundary management practices in the case of selfemployed German lawyers. Qualitative empirical results on the basis of 12 interviews reveal that the institutional context in case of self-employ...

Modern communication standards such as Digital Imaging and Communication in Medicine (DICOM) include nonimage data for a standardized description of study, patient, or technical parameters. However, these tags are rather roughly structured, ambiguous, and often optional. In this paper, we present a mono-hierarchical multi-axial classification code for medical images and emphasize its advantages...

Transmitting digital information using ultra-short pulses, Impulse Radio (IR) has received increasing interest for Multiple Access (MA). Analog IRMA utilizes pulse-position modulation (PPM) and random time-hopping codes to mitigate inter-symbol interference (ISI) and suppress multiuser interference (MUI) statistically. We develop an alldigital IRMA scheme that relies on block-spreading and judi...

In this paper, we describe an approach for the automatic medical annotation task of the 2008 CLEF cross-language image retrieval campaign (ImageCLEF). The data comprise 12076 fully annotated images according to the IRMA code. This work is focused on the process of feature extraction from images and hierarchical multi-label classification. To extract features from the images we used a technique ...

A rapid development is presently underway, where a company's ability to compete is becoming directly dependent upon the effective use of information technology.' The internal organization is becoming more decentralized, and because of this, important information must be available to all employees. This places new demands on the dil'ect commitment of top management in handling the critical resou...

In the past few years, immense improvement was obtained in the field of content-based image retrieval (CBIR). Nevertheless, existing systems still fail when applied to medical image databases. Simple feature-extraction algorithms that operate on the entire image for characterization of color, texture, or shape cannot be related to the descriptive semantics of medical knowledge that is extracted...

A time-resolved immunofluorometric assay (IFMA) is described for quantifying the ovarian carcinoma-associated antigenic determinant CA 125 in human serum. Monoclonal antibody to CA 125 is immobilized onto a microtiter well, and the same antibody labeled with a europium chelate is used as a tracer. After the immunoreaction the bound portion of the labeled antibody is quantified by dissociating t...

BACKGROUND Serum thyroglobulin (Tg) is essential in the follow-up of patients with differentiated thyroid carcinoma (DTC). However, interchangeability and standardization between Tg assays have not yet been achieved, even with the development of an international Tg standard (Certified Reference Material 457 [CRM-457]). METHODS Serum Tg from 30 DTC patients and serially diluted CRM-457 were me...

National electronic identification (eID) systems aim to provide universal, unique and reliable identification and authentication mechanisms to the citizens. Many countries in Europe have already introduced or are about to introduce electronic ID cards to their citizens. The increasing number of eID infrastructures and initiatives have been taken to scale the eID systems to support both eGovernm...
