Automated bus systems are a promising means of future first- and last mile public transport solutions, and can even possibly become a regular part of the public transport network. Therefore, many projects appear throughout Europe to pilot the feasibility of automated bus system implementation on various locations. Keeping up with the rapidly...

In carbonate rocks, channelized fluid flow through fracture conduits can result in the development of large and connected karst networks. These cavity systems have been found in multiple hydrocarbon and geothermal reservoirs, and are often associated with high-permeability zones, but also pose significant challenges in drilling and reservoir...

Dit rapport is een uitwerking van de casestudy Appelscha welke is uitgevoerd in het kader van werkpakket 7 van het STAD project. Het STAD project bestudeert het effect van zelfrijdende voertuigen op vervoers- en locatiekeuzes van personen en bedrijven en op het ruimtelijk ontwerp van steden en wegen. Werkpakket 7 focust binnen het project op de...

In 2016 startte de Verkeersonderneming de aanbesteding ”Marktplaats voor Infrastructuur”. De Marktplaats voor Infrastructuur was een nieuwe manier van aanbesteden waarbij de markt gevraagd werd om een knelpunt op te lossen. Waar normaliter specifiek gevraagd wordt naar een bepaalde oplossing, werden marktpartijen vrij gelaten om zelf de...

The potentials of a double glmballed mcwientum wheel as an actuator for the attitude oontrol of a geostationary communication satellite are discussed with respect to the related systems. A justification of the IXaW is given and the characteristics defining the wheel system are determined. They can serve to be the input to a detailed design of an...

In this report the requirements of orbit control of geostationary communications satellites are investigated. A comparison between chemical and electrical propulsion is made for mission lives up to I5 years. The mass of electrical propulsion is lower than of chemical syetems, even when mass penalties for the low reliability of the ion thrusters...

Due to the finite stiffness of rotor- and gimbal-suspensions, a double gimballed momentum wheel will oscillate with high natural frequencies. The stability of these oscillations is studied, in order to obtain requirements for the stiffness of the suspensions and/or the gimbal inertia properties. From energy considerations, it is concluded that...

In this study a survey is given of laimched satellites, paying special attention to mission objectives and attitude control systems. This picture is extrapolated into the near future to analyse the control requirements that are to be expected for future satellite missions. Possible attitude control systems for satellites are also surveyed and...
