This study examines the uni-axial unconfined compressive strength of stabilized clay mixed with different types of binders [1]. The binders tested were cement kiln dust (CKD), lime (CaO) and ordinary Portland cement (OPC) exclusively or in different combinations. Samples were hardened for...

We consider the Lame form of the elasticity system and demonstrate the famous paradox, which can be obtained by the limit passage in the polygonal plates with very small sides as the length of sides goes to zero. The phenomenon is that boundary conditions in the original problem and the limit...

The design load levels of Arctic offshore structures are likely to be determined by first year sea ice ridges and rubble field. Better understanding of ice rubble will help us to determine this design load level accurate enough. From a set of punch shear tests conducted by Heinonen, J. (2004) in the...

The presentation focus on the U-value of a Con-Form concrete wall, and how it is influenced by varying some of the structural and material properties. Specifically, the influence of the following parameters are analyzed....

Three types of carbon nanotubes(CNT) have been investigated regarding their suitability as spectrally selective solar thermal absorbers.The CNT coatings were electrophoretically deposited on aluminum substrates using kinetically stable CNT aqueous suspensions, of which two CNT aqueous suspensions (N...

Ice loads are core design criteria for hydropower dams in northern regions. They are responsible for a significant proportion of the design load of small dams that are typically used in Norway. In spite of their importance, the magnitude and regional variability of ice loads are still poorly...

In the homogenization theory, there are many examples where the effective conductivities of composite structures are power means of the local conductivities. The main aim of this paper is to initiate research concerning geometric construction of some power means of three or more variables. We...

The main aim of this paper is to contribute to the recently initiated research concerning geometric constructions of means, where the variables are appearing as line segments. The present study shows that all Lehmer means of two variables for integer power k and for k = m 2 , where m is an integer...

In the Arctic, presence of sea ice presents a challenge to safe and sustainable operations. To optimize planning and minimize impact of inadvertent oil spills, oil-in-ice experiments were performed at the HSVA Arctic Environmental Test Basin (AETB) from 14 March to 4 April 2017. Following an under...

In order to improve the knowledge of the real behaviour of existing structures,structural health monitoring (SHM) is usually carried out. Initial calculations of a buttress dam located in Norway has been carried out to evaluate dam safety against the design loads. From this analysis, it was...
