Radio based positioning or tracking solutions typically require wideband signals or phase coherent antennas. In this paper, we present a target tracking method based on received non-coherent signal strength differences (RSSDs) between antennas for outdoor Internet-of-things (IoT) scenarios. We introduce an RSSD model based on classical path-loss models. With known antenna patterns and antenna arra
The Taymyr Peninsula constitutes the eastern delimitation of a possible Kara Sea basin ice sheet. The existence of such an ice sheet during the last global glacial maximum (LGM), i.e. during the Late Weichselian/Upper Zyryansk, is favoured by some Russian scientists. However, a growing number of studies point towards a more minimalistic view concerning the areal extent of Late Weichselian/Upper Zy
This overview examines available circum-Antarctic glacial history archives on land, related to developments after the Last Glacial Maximum (LGM). It considers the glacial-stratigraphic and morphologic records and also biostratigraphical information from moss banks, lake sediments and penguin rookeries, with some reference to relevant glacial marine records. It is concluded that Holocene environmen
A reconstruction of deglaciation and associated sea-level changes on northern James Ross Island, Antarctic Peninsula, based on lithostratigraphical and geomorphological studies, shows that the initial deglaciation of presently ice-free areas occurred slightly before 7400 14C yr BP. Sea-level in connection with the deglaciation was around 30 m a.s.l. A glacier readvance in Brandy Bay, of at least 7
A small bedrock ridge called Cuff Cape, protruding from an ice field in the inner part of Granite Harbour, Victoria Land, Antarctica, carries a system of moraine ridges. Cuff Cape was during deglaciation bounded to the south by a terrestrial, slow-retreat ice margin and towards the north and west by a faster-retreat, marine-based ice margin. Based on studies of contemporary processes along the pre
The Visdalen valley, situated at the northwestern corner of Edgeoya, was investigated with respect to lithostratigraphy and depositional environments of the Quaternary sediments. Eight major lithostratigraphic units are recognised of which seven were deposited during the Late Weichselian to early Holocene glaciation, deglaciation and the subsequent emergence of the area, and one unit deposited pri
The eastern part of the Svalbard archipelago and the adjacent areas of the Barents Sea were subject to extensive erosion during the Late Weichselian glaciation. Small remnants of older sediment successions have been preserved on Edgeoya, whereas a more complete succession on Kongsoya contains sediments from two different ice-free periods, both probably older than the Early Weichselian. Ice movemeh
Small rafts of floating sediment, predominantly of granule and small pebble size, were observed along a tidewater coast on James Ross Island, Antarctica. The sediment was lifted from the beach by the advancing tidewater and kept afloat by surface tension. The current transported the rafts at least 100-150 m off the beach, where the rafts broke up due to wind agitation of the sea surface and the gr
A central issue in studies of second and foreign language acquisition and of bilingualism is to understand what happens when two or more languages come into contact within a person, a domain often referred to as crosslinguistic influence. This chapter begins with an introduction to the notion of convergence and outlines some key theoretical issues and empirical findings. It introduces bimodal conv
The Late Quaternary (c. 130000-10000 BP) glacial history of the central west coast of Jameson Land, East Greenland. is reconstructed through glacial stratigraphical studies. Seven major sedimentary units are described and defined. They represent two interglacial events (where one is the Holocene). one interstadial event and two glacial events. The older interglacial event comprises marine and fluv
The plateaus between 400 and 800 m a.s.l. around the water-divides on central and eastern Janieson Land are covered by the ‘Jameson Land Drift’ up to 50 m thick glacial. placiotluvial and glaciolacustrine deposits. A high content of far-travelled wcsterii rocks indicates the overriding by extensive glaciers channelled from the west through the Scoresby Sund basin. The Jameson Land Drift deposits h
Late Weichselian litho-, bio-, and chronostratigraphy (14C and varves) in southeastern Sweden provide a detailed picture of the deglaciation pattern and dynamics, shore displacement, late-glacial sedimentation, and history of the landscape, vegetation, and climate. Two plausible glacial models were tested against lithologic, chronologic, and climatic data. Permafrost at and outside the ice margin
Group work is increasingly used in higher education and is associated with several benefits, both for the students and the teacher. How groups are assigned is of significance for the success of group work. This study aspires to explore the ways in which teachers can assign groups in order to enable successful group work. The findings indicate that heterogeneous groups that consist of students with
We present an approach for the estimation of ore processing residue volumes in historical mine waste dumps by the use of different geophysical methods in combination with mineralogical investigations. The stamp mill dump in the Harz mountains, Germany was examined with the methods electrical resistivity tomography (ERT), ground penetrating radar (GPR) and spectral induced polarization (SIP) flanke
Tandläkare och tandhygienister graderar beprövad och personlig erfarenhet som bas för sunt beslutsfattande högre än de som jobbar inom hälso- och sjukvården. Varför det är så är inte enkelt att besvara, men det är rimligt att anta att tandläkarnas syn på beprövad och personlig erfarenhet påverkas av rådande kunskapsläge, den organisation inom vilken de verkar samt gällande lagar och förordningar.
Greater Copenhagen is often cited as a good example of cross-border cooperation. Shared historical contexts and socio-political willingness have meant that considerable resources have been invested into the development of infrastructure in this region. The Öresund fixed link constitutes the most important element of this infrastructure, facilitating a cross-border public transport system which tie
Aim: The present study investigates the effect of signal degradation on perceived listening effort in children with hearing loss listening in a simulated class-room context. It also examines the associations between perceived listening effort, passage comprehension performance and executive functioning. Methods: Twenty-four children (aged 06:03–13:00 years) with hearing impairment using cochlear i
