Van Kasteren, J. (author)Even concrete is not as hard as it looks. Sea water, salt on icy roads, and indirectly even carbon dioxide from the air can corrode the steel of the reinforcing bars and so threaten the strength and integrity of a bridge pier, jetty, or viaduct. Dessi Koleva, a chemical engineer from Bulgaria, spent her doctoral research at the Faculty of Civil...journal article 2006

Van Kasteren, J. (author)The high cost of an electron microscope makes remote collaboration a sure-fire way of increasing the operational efficiency of this type of equipment. A pathologist can now be consulted from a remote location by the microscopist, and a manager at a steel plant can discuss a problem with the researcher at a metallurgical institute, with both...journal article 2005

Van Kasteren, J. (author)In 1881 Hendrik Willem Mesdag painted his famous Panorama of the fishing village of Scheveningen. The panorama covers a cylinder 14 metres high with a circumference of 120 metres. It is in fact an early form of virtual reality, giving the viewer the illusion of participating in life on the seashore. Like a modern Mesdag, Aldo Hoeben, part-time...journal article 2004

Van Kasteren, J. (author)Bacteria, polyps, ants, and bees are the living proof that, given inhospitable conditions, colonies stand a better chance of survival than individuals.At TU Delft, this biological principle is now being used on spacecraft. A colony of micro satellites will be less vulnerable than a normal satellite, not only to gamma radiation and solar storms,...journal article 2004

Van Kasteren, J. (author)It happens all the time. Seduced by a glossy catalogue or an image on a web site you step into the shop to buy yourself a new toaster or computer display. Once there, disappointment strikes. The toaster is just another tin box, and the sleek computer screen from the brochure turns out to be huge. The reverse also happens.journal article 2004

Van Kasteren, J. (author)During the initial stages of the design process, industrial designers often use their private collection of images, magazines, and objects to gather ideas and to discuss matters with their colleagues. These collections are rather like the cabinet of curiosities or wunderkammer that the well-to-do of the sixteenth and seventeenth centuries liked...journal article 2004

Van Kasteren, J. (author)The weight of people and luggage makes the conveyor belts at Schiphol Airport sag a little, causing extra wear to both the plastic guide rollers and the rubber conveyor belt itself. Together with Karel Drenth, Gabriel Lodewijks, Professor of Transport Engineering & Logistics at Delft University of Technology, has devised a suspension system in...journal article 2003

Van Kasteren, J. (author)There were remarkable scenes in Adelaide, Australia,on the afternoon of Wednesday 22 October 2003 when a swathe of orange spilled through the city. Barely visible at the heart of this burst of colour was the Nuna II, a futuristic vehicle which had just won the Solar Challenge 2003, a four-day journey of more than 3000 kilometres across...journal article 2003

Van Kasteren, J. (author)The car boot of practically any car appears to be pretty low on the list of items the manufacturer considers important.The world of glossy, state of the art and high-tech design seems to come to a halt behind the rear seat. Designers at Audi, the German car manufacturers, were well aware that this part of the car had been neglected and that it...journal article 2003

Van Kasteren, J. (author)The action of any pump will start to decline when the valves no longer close properly. The same goes for the heart, the pump that maintains the circulation in our vascular system. Consequently, a major field of focus of open heart surgery is the repair or replacement of heart valves. Petr Havl a Ph.D. student at the Man Machine Systems section...journal article 2003

Van Kasteren, J. (author)Every year, despite today's advanced electronic guidance systems, a handful of aircraft still plough into mountains in most cases killing all occupants. Such accidents are usually caused by a combination of low visibility and difficult terrain conditions. In mountainous terrain the modern precision guidance system known as the Instrument Landing...journal article 2002

Van Kasteren, J. (author)More eloquent alternatives to the harsh tones of the oldfashioned alarm-clock bells abound, including a newsreaders voice summing up last nights disasters, or a tape of your favourite early morning music. Still, getting out of bed has its difficult moments. All this could well change in the near future, if Ir. Stephan Wensveen, a graduate...journal article 2002

Van Kasteren, J. (author)Children often talk to the Lego bricks theyre playing with. When they grow older, theyll give their computer a name, and later still, theyll have a pet name for their first car. People like to talk to inanimate objects, as if they are talking to a partner or colleague. Until now, few of the machines we talk to have had anything to say in return...journal article 2001

Van Kasteren, J. (author)If a manufacturer wishes to combine two or more existing products into a new "hybrid" product, he needs to pay special attention to the way in which the product is to be marketed. The fact is that it may prove difficult to sell if consumers cant readily recognise the new product combination. Failure to clearly define the hybrids position in the...journal article 2001

Van Kasteren, J. (author)Many surgeons find it difficult to perform laparoscopies, operations performed inside the abdominal cavity without opening the abdominal wall. These keyhole operations are particularly taxing due to a lack of depth perception and impaired hand-eye coordination. Consequently, the method has been used for relatively simple operations only. A new...journal article 2001

Van Kasteren, J. (author)X-ray and gamma radiation are widely used in hospitals and laboratories, and in the manufacturing and mining industries. Several methods exist for making the radiation "visible", including scintillators, films, and semiconductor materials. Scintillators are crystals that convert ionising radiation into visible light. This is a field in which...journal article 2001
