'In the past few years the concepts of the Task Oriented Programming (TOP) paradigm have been developed. TOP can be used for the design and implementation of applications where people have to collaborate to achieve a common goal. Command and Control (C2) systems areprime examples of such applications. …

Military systems are operated in a variable way and operating conditions are generally quite demanding. At the same time, the requirements in terms of availability and reliability are high, and strict budget limitations make that the maintenance activities must be carefully planned and executed. The …

For the simulation of a flexible helicopter rotor system the Euler equations for a rotating and translating beam structure are derived using the Finite Element technique. Using the displacements and velocities of a beam element which has an airfoil shaped cross section the aerodynamic forces and moments …

Global Navigation Systems, like GPS, are widely used for positioning, timing and many other topics in both the civil and military world. Such a system in an extraordinarily useful utility that is inexpensive to use, but on the other hand, it is a technology that introduces major and often times poorly …

Life-cycle costing (LCC), originally developed by the US DoD, promises integrated insight in investment, maintenance, usage and disposal costs of weapon systems. In an era of tightening budgets, these opportunities have led to programs to tailor and implement LCC. At present, conceptual development of …

The current Dutch Walrus-class submarines count over a hundred hydraulic actuators, including the rudders, the periscope and the integrated torpedo and harpoon system. Al these devices are controlled with petroleum based, and therefore flammable, hydraulic oil. Replacing these hydraulic actuators on …

In the present work the possibility to use Liquefied Natural Gas as a fuel for naval ships has been investigated. The main research question is: "Is it viable to convert the hydrographic survey vessels to the use of Liguefied Natural Gas (LNG) as fuel?" More specifically the focus lay on how to convert …

The complexity and dynamics of current military operations demand reliable and up-to-date intelligence and in particular near-real-time threat assessment. This paper explores the potential of operational analysis techniques in supporting military personnel in processing information from different sources, …

In this paper the authors illustrate developments in sensor technology with a number of examples. From their own research they discuss radar, image processing and sensor networks. Radar performance is affected by propagation characteristics of electromagnetic waves. Experience has shown that this may …

In an increasingly technology-driven world it is natural to ask what exactly are the expectations and limitations of novel technologies in a particular domain. Military technology has a high-tech imago that is not always justified by the facts. However there is no doubt that the military is a powerful …
