Evaluation of Load transfer in rigid pavements by Rolling wheel deflectometer and Falling weight deflectometer

2020

Abstract Rigid pavements have widespread use, e.g, in motorways and airports, due to their excellent properties such as high bearing capacity and long lifetime. However, when rigid pavements fail it is often due to bad load transfer efficiency (LTE) at its joints. Traditional methods of measuring LTE can be time consuming. Here, we study the possibility of measuring LTE using a moving load with the aim of achieving higher productivity. An experiment simulating Rolling Weight Deflectometer (RWD) measurements on a joint was carried out to gain understanding and confidence that can guide the analysis of real RWD data. Continuous data from measurements across a joint allows for determination of…

Spectro-temporal reflectance surfaces: a new conceptual framework for the integration of remote-sensing data from multiple different sensors

2012

The conflict between spatial and temporal resolution of satellite systems, as well as the frequent presence of clouds in the images, has been a traditional limitation of remote sensing in the optical domain. Nevertheless, most of the conceptual tools and algorithms developed classically in remote sensing are based on the input of a series of cloud-free images from identical sensors. In this study, we propose a conceptual framework that is able to ingest data from several different sensors, make them homogeneous, eliminate clouds virtually, and make them usable in a flexible, efficient, and transparent way. The methodology is based on previous developments such as spatial ‘downscaling’, temp…

Policy and Governance for Sustainable Consumption at the Crossroads of Theories and Concepts

2016

This introductory article of the special issue compares different conceptual underpinnings of efforts to make the everyday activities of consumers more sustainable. As social practice theory (SPT) is the main theoretical foundation of the articles collected here, we outline its strengths and limitations, when compared with the dominant individual-oriented behaviour change approach, and we focus on theories of planned behaviour, social marketing as well as ‘choice architecture’, based on behavioural economics. This article analyses SPT's usefulness, particularly from the applied point of view for policy-makers and social change programme designers. In the final section we provide some recomm…

Chapter 15 Pain and itch in Wallenberg's syndrome: anatomical–functional correlations

2006

Publisher Summary The Wallenberg syndrome or dorso-lateral medullary infarction is the most common vascular syndrome of the medulla oblongata. Its clinical features include an ipsilateral Horner's syndrome, an ipsilateral limb ataxia, and mostly an ipsilateral but sometimes also a contralateral or bilateral decrease of pain and temperature sensibility of the face. Patients with Wallenberg's syndrome and with morphological (lesion) or functional (ipsilateral sensory deficit and delayed late blink reflex responses) show evidence of damage to the trigeminal tract and nucleus with sparing of the nucleus caudalis would develop facial pain. The trigeminal trophic syndrome (TTS), a very rare compl…

Development of a multispectral imagery device devoted to weed detection

2003

Multispectral imagery is a large domain with number of practical applications: thermography, quality control in industry, food science and agronomy, etc. The main interest is to obtain spectral information of the objects for which reflectance signal can be associated with physical, chemical and/or biological properties. Agronomic applications of multispectral imagery generally involve the acquisition of several images in the wavelengths of visible and near infrared. This paper will first present different kind of multispectral devices used for agronomic issues and will secondly introduce an original multispectral design based on a single CCD. Third, early results obtained for weed detection…

Diagnostic Localizing Value of the Electrically Elicited Blink Reflex

1993

The blink reflex (BlinkR) following electrical stimulation of the supraorbital nerve consists of an early ipsilateral reflex component (R1) and bilateral late reflex components ipsilaterally (R2) and contralateral (R2c). An additional, and even later component, also bilateral, R3, R3c was first described by Penders and Delwaide [34] and so far has not been studied systematically.

Theorizing a one-semester real customer student software project course

2011

Project courses in software engineering education have, roughly speaking, as long a history as the term software engineering itself — about 40 years. Several project course models have been described in the literature, including the research target of the dissertation, a one-semester course where students develop software in small groups for real customers. The long history of the research field constitutes a challenge for new research. The research approach of this dissertation is theorizing in the sense of classical grounded theory. The motivation behind this theorizing approach was the possibility of finding fresh viewpoints in a long-established research field and a need to give structure …

Ikä, identiteetti ja ohjaava koulutus. Ikääntyvät pitkäaikaistyöttömät oppimisyhteiskunnan haasteena

2007

Piia Silvennoinen tutki väitöskirjassaan, millainen merkitys työvoimapoliittisella koulutuksella on ikääntyvien pitkäaikaistyöttömien elämässä. Koulutusten oletetaan parantavan ikääntyvien pitkäaikaistyöttömien työmarkkinakelpoisuutta ja elämänhallintaa. Silvennoinen haki vastausta siihen, miten ikääntyvät pitkäaikaistyöttömät itse suhtautuvat työvoimapoliittisiin koulutuksiin; onko niistä heille haittaa vai hyötyä. Silvennoinen kertoo, että koulutuksen hyödyllisyyttä arvioidaan sen työllistävän vaikutuksen kautta. – Mitä vähemmän koulutus työllistää, sitä enemmän myös sen muut merkitykset menettävät arvoaan ikääntyvien pitkäaikaistyöttömien elämässä, Silvennoinen toteaa. Nykyinen itseohjau…

Can Do and Cannot Do – CEFR inspired examination and assessment in a Swedish higher education context

2018

The focus in this paper is on the introduction and implementation of learning outcomes based on the descriptors in the Common European Framework of References for Languages (CEFR). It discusses reaction to the introduction by teacher educators as well as the influence on teacher assessment practice in courses for prospective teachers of English as a foreign language. The paper presents some of the results from a case study concerning changes made in connection with the Bologna process in a department of education within a university college in Sweden. The results show that the adoption of the CEFR descriptors was contested and had a minimal influence on assessment practice. The aim of the p…
