(Master thesis, 2019)Konfidensiell til / confidential until 01.07.2024 -
Testing av mekanisk påkjenning på solcelle
(Master thesis, 2012)Solenergi industrien er den raskest voksende fornybar energi-sektoren over hele verden; reduksjon av silisium wafer tykkelse uten å øke wafer styrke kan føre til en høy brudd-prosent under påfølgende håndtering og prosessings ... -
The effect of feedstock origin and temperature on the structure and reactivity of char from pyrolysis at 1300–2800 °C
(Journal article; Peer reviewed, 2019)This study reports the effect of feedstock origin, residence time, and heat treatment temperature on CO2 and O2 reactivities, nanostructure and carbon chemistry of chars prepared at 1300, 1600, 2400, and 2800 °C in a ... -
The finding and dynamic detection of opinion leaders in social network
(Journal article; Peer reviewed, 2014)It is valuable for the real world to find the opinion leaders. Because different data sources usually have different characteristics, there does not exist a standard algorithm to find and detect the opinion leaders in ... -
The Gantry-Tau parallel kinematic machine-kinematic and elastodynamic design optimisation
(Journal article; Peer reviewed, 2011)One of the main advantages of the Gantry-Tau machine is a large accessible workspace/footprint ratio compared to many other parallel machines. The optimal kinematic, elastostatic and elastodynamic design parameters of the ... -
The harp: a vehicle crash test apparatus for full-scale crash test experiments
(Journal article; Peer reviewed, 2012)The current paper describes an apparatus for full-scale vehicle crash test experimentation. This apparatus is referred to as the harp. In brief, the harp may either accelerate a trolley which is impacted into a test vehicle ... -
The identification of convex function on riemannian manifold
(Journal article; Peer reviewed, 2014)The necessary and sufficient condition of convex function is significant in nonlinear convex programming. This paper presents the identification of convex function on Riemannian manifold by use of Penot generalized directional ... -
The impact of the subsidy policy on total factor productivity : an empirical analysis of China's cotton production
(Journal article; Peer reviewed, 2013)This paper develops one model to explore the relationship between the subsidy policy and the agricultural total factor productivity (TFP). It indicates that the agricultural TFP will be lower after the subsidy policy is ... -
The limiting efficiency of four-band cells revisited
(Journal article; Peer reviewed, 2014)The limiting theoretical efficiency of four-band solar cells is revisited. In previous work, researchers have looked at the theoretical efficiency of four band cells where the smallest of the three sub-band gaps is closest ... -
The nature of rest silanol groups on the surfaces of silica based solid phase extraction materials
(Journal article; Peer reviewed, 2013)Chemically bonded solid phase materials are very important in separation chemistry. The chemically modified silica gel contains rest silanol groups that can affect the retention properties when they are used for separation ... -
The performance investigation of viscoelastic hybrid models in vehicle crash event representation
(Chapter; Peer reviewed, 2011)This paper presents application of physical models composed of springs, dampers and masses joined together in various arrangements to simulation of a real car collision with a rigid pole. Equations of motion of those systems ... -
