The ESA Sentinels constitute the first series of operational satellites responding to the Earth Observation needs of the EU-ESA Global Monitoring for Environment and Security (GMES) programme. The GMES space component relies on existing and planned space assets as well as on new complementary developments by ESA. This paper describes the Sentinel-1 mission, an imaging synthetic aperture radar (...

The posterior femoral cutaneous nerve (PFCN) is a branch of the sacral plexus. It needs to be implemented as a complementary block for anesthesia or in the surgeries necessitating tourniquet in the suitable cases. We consider target oriented block concept within the PFCN block in the anesthesia implementations with the emergence of ultrasonic regional anesthesia in the practice and with the bet...

This paper describes the in-orbit calibration aspects for the Sentinel-1 mission. ...

When considering an existing ontology for reuse to annotate new data, one needs to check if the ontology contains classes and properties suitable for describing the data. Visualizing the ontology itself in some of the available tools, to support such a decision, is an obvious option. We propose that ontology usage visualization, a slight variant of dataset schema visualization, might however be...

The recent progress is reviewed and future prospects of silicon photonics in next generation communication and computing systems are probed. Leveraging the many-billion-dollar complementary metal-oxide-semiconductor (CMOS) industry, silicon photonics has promising prospects for realising very large-scale electronic and photonic integrated circuits with thousands of optical components and millio...

Introduction We are currently witnessing a change in scholarly communication. Next to the paper, complementary materials, such as research data, source code, and images are regarded as important outcomes that should be shared and built upon (Kraker et al., 2011). In this new ecosystem, many archives have been established that cater to the needs of a digital and open science. With the increasing...

Emphasis on the advantages of breast-feeding to the infant and to the nursing mother has been accompanied by resurgent interest in this practice. Although breast-feeding has many desirable features, the needs of the lactating mother and her nursing infant may not always be complementary. Possible competition between the mother’s requirement for adequate contraception and the infant’s nutrition ...

Based on the "complementary-congruence model" of person-environment fit, this study focuses on housing in old age as an interaction between housing needs and housing conditions in urban settings. The research aims are (1) to establish a set of housing-related person-environment (p-e) fit indices based on the relationship between environmental needs and existing conditions in different physical ...

With constant advances in information technology, more and more information is available and users’ information needs are becoming more diverse. Most conventional information systems only attempt to provide information that meets users’ specific interests. In contrast, we are working on ways of discovering information from the viewpoints of both interest and necessity. For example, we are tryin...
