Good and efficient care for our elderly is a major concern in our ever aging popu- lation. The elderly’s greatest fear is falling to the ground, not being able to get up or get help. Use of Bluetooth motion sensors and appropriate agents can help alert for in the event of a person falling. In this master thesis an experimental sensor rig has been created together with an android application which ...

Brannsikring av ventilasjonssystemer har fått svært mye fokus de siste årene, på grunn av uklare retningslinjer for prosjekterende. TEK10 setter kun funksjonskrav for hvordan tekniske installasjoner skal brannsikres, og det er dermed opp til de prosjekterende å sette opp løsninger innenfor lovverket. På bakgrunn av det uklare regelverket ble det nedsatt en gruppe med rådgivere for å utarbeide en ...

We derive necessary and sufficient conditions (of Muckenhoupt-Bradley type) for the validity of q -analogs of (r, p) -weighted Hardy-type inequalities for all possible positive values of the parameters r and p . We also point out some possibilities to further develop the theory of Hardy-type inequalities in this new direction.

We consider the q-analog of the Riemann-Liouville fractional q-integral operator of order n∈Nn∈N. Some new Hardy-type inequalities for this operator are proved and discussed.

In a bounded domain with a thin periodically punctured interface we study the limit behavior of the bottom of spectrum for a Steklov type spectral problem, the Steklov boundary condition being imposed on the perforation surface. For a certain range of parameters we construct the effective spectral problem and justify the convergence of eigenpairs.

The paper deals with the Neumann spectral problem for a singularly perturbed second-order elliptic operator with bounded lower order terms. The main goal is to provide a refined description of the limit behaviour of the principal eigenvalue and eigenfunction. Using the logarithmic transformation, we reduce the studied problem to an additive eigenvalue problem for a singularly perturbed Hamilton–Jacobi ...

The increased production of more and more complex products challenges the accuracy of manual welding, and increase the time it takes to program automatic welding systems. The main objective for the article is to explore if current regulations and standards are able to accommodate the shift from automatic welding to autonomous welding systems. To do this, the most current and applicable standards ...

Developing a sensitive and effective instrument for detecting the presence of red dye in diesel fuel is very advantageous for governments in preventing tax loss by controlling illegal use of the diesel fuel. The objective of this work has been to investigate and develop an instrument to detect red dye in diesel, based on the principle of absorption. The peaks of absorption in red and pure diesel ...

Atmospheric icing on wind turbines have been recognized as a hindrance to the development of the wind power in cold regions, where uncertainty surrounding the effects of icing on energy production may prevent otherwise good wind resources from being utilized. This research paper is focused on to numerically simulate the rate and shape of atmospheric ice accretion on a full-scale horizontal axis ...

The Zeppelin observatory is a research station near the village Ny-Ålesund in Svalbard. The facility delivers data to international projects devoted to high data quality monitoring of the background air pollution in the Arctic. An approach for quantifying the influence of local and regional pollution on measurements that may be misinterpreted as long-range transported one, is presented here. The ...
