A key challenge in developing companion agents for children is keeping them interested after novelty effects wear off. Self Determination Theory posits that motivation is sustained if the human feels related to another human. According to Social Penetration Theory, relatedness can be established through the reciprocal disclosure of information...

Described is the M1 segment support, as designed by TNO in the period 2015- 2016. The design has significantly changed and improved compared to the earlier designs. During the period 2009-2010 prototypes for the primary mirror support of the E-ELT have been developed. These have been extensively tested by ESO. Design improvement were found to be...

Wear and tear, electrification and aging of (low voltage) distribution grids require maintenance in order to assure continuous provision of electricity. Situational awareness is required to find out when parts of the grid need maintenance and which parts should be prioritized. The paper proposes a conceptual value model which relates sensor data...

ESO is preparing to build the E-ELT which will be the largest optical telescope in the world. Its primary mirror will be Ø39.3 m and will consist of nearly 1000 hexagonal segments of 1.2 meter width. Each segment is to be supported by the same structure although the segments vary in size and shape, hence this will cause variable surface...

The largest optical telescope in the world will be the E-ELT. Its primary mirror will be 42m in diameter. This mirror will consist of 984 hexagonal segments that are all individually supported. Each mirror will be controlled in six DOF while local shaping of the segments is provided by so called warping harnesses. These will correct for focus,...

Geophysical investigations were carried out on two modern landfill sites in the Netherlands. The objective of the geo-electrical and EM31 measurements was to reveal the effect of recirculation of leachate on homogenising moisture content in the waste to stimulate the process of attenuation. At Vlagheide, geo-electrical and EM31 measurements were...

To measure the relative motions of GAIA's telescopes, the angle between the telescopes is monitored by an all Silicon Carbide Basic Angle Monitoring subsystem (BAM OMA). TNO is developing this metrology system. The stability requirements for this metrology system go into the pico meter and pico radian range. Such accuracies require extreme...

The two most important characteristics of opto-mechanical structures used in space or for astronomy are high accuracy and stability. Much time, money and energy is invested in achieving this. However, because resources are limited, it is important to realize that the cost of an instrument is mainly determined during the design process. Three...

After consulting the building industry the Dutch government decided in February 1998 to implement sustainability requirements in the Dutch Building Decree by the year 2001. Part of these requirements will be the material-based environmental performance of a building, mepb.. An energy performance requirement for buildings is already part of the...

In February 1998 the Dutch government decided to implement sustainability re-quirements by the year 2001 in the Dutch building Decree. Part of these require-ments shall be a performance requirement for the environmental influence of the total use of materials, determined by LCA (life cycle analyses), for dwellings or residential buildings. In...
