Transmission Spectra of an Electrochromic Window based on Polyaniline, Prussian Blue and Tungsten Oxide
(Journal article; Peer reviewed, 1993)The demand for energy savings in buildings will increase in the coming years, as the world's attention is drawn towards environmental aspects and energy economizing. Windows which are able to dynamically control the sun ... -
REACTION TO FIRE CLASSIFICATION OF BUILDING PRODUCTS: ASSESSMENT OF THE SMOKE PRODUCTION: Hazard Assessment, ISO Fire Test Methods and Development of Empirical Smoke Prediction Models
(Dr.ingeniøravhandling, 0809-103X; 1994:130, Doctoral thesis, 1994)The thesis presents a comprehensive study on assessment of smoke production properties of building products. Primarily the hazard related to the loss of visibility is considered. The starting point has been to investigate ... -
On some methods of downward continuation of mean free-air gravity anomaly
(Journal article, 1998)This paper investigates four methods of downward continuation of free-air gravity anomalies to sea-level, an iterative process based on the Poisson's integral, a linear simple formula, a method based on the Pellinen ... -
Behaviour of saturated sand under different triaxial loading and liquefaction

The direct topographical correction in gravimetric geoid determination by the Stokes-Helmert method
(Peer reviewed; Journal article, 2000)The direct topographical correction is composed of both local effects and long-wavelength contributions. This implies that the classical integral formula for determining the direct effect may have some numerical problems ... -
Precise geoid determination over Sweden using the Stokes-Helmert method and improved topographic corrections
(Peer reviewed; Journal article, 2001)Four different implementations of Stokes's formula are employed for the estimation of geoid heights over Sweden: the Vincent and Marsh (1974) model with the high-degree reference gravity field but no kernel modifications; ... -
Two different views of topographical and downward-continuation corrections in the Stokes-Helmert approach to geoid computation
(Peer reviewed; Journal article, 2001)Two different methods to handle the topographical and downward-continuation corrections in Stokes' formula are investigated. The first approach is to correct observed gravity anomalies for the the effect of topographic ... -
Two different methods of geoidal height determinations using a spherical harmonic representation of the geopotential, topographic corrections and the height anomaly-geoidal height difference
(Peer reviewed; Journal article, 2002)It is suggested that a spherical harmonic representation of the geoidal heights using global Earth gravity models (EGM) might be accurate enough for many applications, although we know that some short-wavelength signals ... -
Some Aspects of Physical Weather Related Slope Processes
(Dr. ingeniøravhandling, 0809-103X; 2002:19, Doctoral thesis, 2002)It is well-recognized that pore water has an important role on the stability of slopes. In this project the principal objective has been to examine the influence of weather on the ground water regime in a quick clay deposit ... -
Geometrisk modellering av veger i 3D
(Doktoravhandlinger ved NTNU, 1503-8181; 2, Doctoral thesis, 2002)There will always be a need for road engineers to have access to suitable applications in order to execute road constructions. An application has to be both flexible and efficient, while at the same time describing the ... -

Use of global geopotential models for comparison of gravimetric geoid estimators by the modification of Stoke's formula
(Peer reviewed; Journal article, 2003)Considering today struggles towards the 1-cm geoid, in an attempt to study the efficiency of some geoidal height estimators, Molodensky et al. (1962), Wong and Gore (1969), Vincent and Marsh (1974), Sjöberg's least-squares ... -
Mixed Hardening Models for Frictional Soils
(Dr. ingeniøravhandling, 0809-103X; 2003:21, Doctoral thesis, 2003)A new material model mainly for frictional soil is developed and implemented in a finite element program. The model is applied to simulate a deep excavation with a supporting tie back wall. The model is based on ... -
A Comparison of the classical and recent formulae of handling the effects of close and distant topographic masses in gravimetric geoid computations
(Journal article; Peer reviewed, 2003)Different procedures for considering the effects of topographic masses in Stokes- Helmert scheme of geoid determination are reviewed. Classical integral formulae use a planar approximation of the geoid and a limited area ... -

The Quest for a Precise Geoidal Height Model
(Peer reviewed; Journal article, 2004)The geoid is defined as an equipotential surface of the Earth�s actual gravity field inside the topographical masses on land (in most cases) and more or less coinciding with mean sea level at sea. Over the last decade, ... -
The direct effect and downward continuation correction of atmospheric masses in gravimetric geoid determination
(Peer reviewed; Journal article, 2004)A new procedure to the direct atmospheric gravity effect in connection with Stokes's integral formula was presented by Nahavandchi (2002). This formula was derived by combining the local contributions of the effect of ... -
A new strategy for the atmospheric gravity effect in gravimetric geoid determination
