Marl, or calcareous clay, is considered ”bad” clay for production of burnt clay products since it is clay contaminated with substantial amounts of calcium carbonate. Calcined marl is proven to be an effective pozzolan in cementitious products and for this reason marl can be a large resource that is...

We present an algorithm for vessel routing that handles inventory constraints, that is, some ports may have storages where product is continually produced or consumed, and where stockout and overflow must be prevented....

The paper presents the optical, mechanical, and electro-optical design of an interferometric inspection system for massive parallel inspection of Micro(Opto)ElectroMechanicalSystems (M(O)EMS). The basic idea is to adapt a micro-optical probing wafer to the M(O)EMS wafer under test. The probing wafer...

The rheology of concrete is often approached by using a particle-matrix model, which roughly can be described as coarser aggregate dispersed in a suspension of fines less than 125 mu m. Parameters determining the flow resistance (taken as the area under the shear stress versus shear rate curve) of...

Recent experience on characterising the presence and distribution of trace elements in recycled aluminium alloy is described.  Two mass spectroscopic techniques, Glow Discharge Mass Spectrometry (GDMS) and Secondary Ion Mass Spectrometry (SIMS) have been applied to the study of commercial...

Self intersecting surfaces can be a consequence of several standard CAD operations for generating freeform NURBS surfaces. In this presentation we will focus on computing the exact topology of the self intersection curves of a NURBS-surface. The self intersections are computed using recursive...

A surface embedded temperature sensor has successfully been fabricated on a customized industrial bolt. The aluminum substrate of the bolt was electrically isolated by plasma electrolytic oxidation followed by the fabrication of a type T thermocouple and finally covered by a wear resistant DLC...

The 13C DD-MAS spectra of six ethene/1-hexene (E/H) copolymers were fitted simultaneously to a sum of four pseudo Voigt functions in which two were assigned to the alltrans crystalline region. These two peaks possessed the same chemical shift but differed in both line width and line shape. Regarding...

We present a low-cost, miniaturised, yet highly sensitive microphone, consisting of a nitride membrane and a diffractive Fresnel lens micromachined on the same chip. The membrane and the reflective Fresnel lens form an interferometer, and the displacement is read by measuring light intensity at the...

Ensuring crew health and safety is a prime concern in spacecraft and other closed manned habitats. Therefore ESA (European Space Agency) has a long term research and development programme where SINTEF is developing advanced air quality monitoring technology in co-operation with Kayser-Threde GmbH...

Drikkevannsforskriften stiller krav om tilstedeværelse av minst to hygieniske barrierer i alle godkjenningspliktige vannforsyningssystemer. Veilederen til drikkevannsforskriften angir at den enkelte vannbehandlingsmetode bør fjerne eller inaktivere bakterier og virus med minimum 99.9 % (3-log) og...

The health care systems of the industrialized countries are expected to undergo major changes within the next 10 - 15 years. The number of elderly people requiring treatment will grow considerably, socalled welfare diseases is increasing, and increasing use of new advanced treatments will occur...

In this study indoor air humidity and temperature levels have been measured in 87 houses in Trondheim, Norway. The temperature and relative humidity were measured at 15 minutes interval over a period of one week. The measurements were made in bedrooms, living rooms, bathrooms and outdoors. The...
