Van Waterloo tot Uruzgan : De militaire identiteit van Nederland
No full textWat kan het vakgebied van de militaire geschiedenis bijdragen over een land met een non-militair zelfbeeld en zeer weinig gevechtservaring (als het om landsverdediging in Europa gaat)? Deze vraag staat centraal tijdens de oratie van Wim Klinkert. Hij stelt onder andere dat we moeten zoeken naar de militaire identiteit die er wél is in de Nederlandse geschiedenis maar naar de achtergrond wordt gedrukt door het dominante non-militaire zelfbeeld. Daarnaast is het belangrijk om zichtbaar te maken dat Nederland in zijn militaire voorbereidingen op oorlog en zijn handelen in crisisperioden (zoals de Eerste Wereldoorlogen) niet anders handelt dan andere Europese landen. Klinkert pleit tot slot voor een internationaal vergelijkende/cultuurhistorische aanpak om de vermeende uniekheid van Nederland te relativeren of te verklaren

Bologna Meets the Battlefield – Using Historical Battlefields in Modern Academic Military Education
No full textTraditionally Staff or War Colleges used battlefields from the past as training tools for officers. Analysing and discussing historical military confrontations on the location that these confrontations had taken place, is thought to increase the understanding of officers about the realities of war and improve their decision making in the future. In many ways, it is a very practice-orientated method of education military professionals. Its aim is not to turn the officers into academic military historians. A more reflective or academic approach to educational visits to battlefields seemed, from the military standpoint, unnecessary. But because in recent years, military education has reached the level of its civilian academic counterpart more and more, the battlefield tour has to adjust to that level as well. That is why we need more thorough academic reflection on this didactical tool. This process started about two decades ago, but needs to be developed further. Not only because of the creation of military educational curricula that follow civilian academic standards, but also to find affiliation with cultural historians and historians of memory, lieu de mémoire and tourism, who increase our understanding of the battlefields of the past. This chapter examines the Dutch effort to create a battlefield tour that both meets academic standards on bachelor level as well as gives cadets professional insights into the ‘realities of war’, which are relevant for their future work as subaltern officers. Based on the philosophy of the ‘thinking soldier’, but also rooted into the history of military education, this academic version of the battlefield tour should help officers in training developing critical thought and skills for academic analysis
(Nederlandse) neutraliteit
No full textProf. dr. Wim Klinkert, Hoogleraar Militaire Geschiedenis en verbonden aan zowel de NLDA als de UvA, praat met ons over Nederlandse neutraliteit, de rol van de krijgsmacht hierbij en waarom het begrip neutraliteit niet zo eenduidig is als vaak gedacht.

Floating WIM Threshold Concept for Truck Weight Enforcement
No full textWeigh stations are the primary weight compliance checkpoints for commercial trucks. In the past several decades, states have used weigh-in-motion (WIM) technology to reduce delay and increase enforcement on overweight vehicles. This study offers a detailed analysis of weigh station systems and presents floating-threshold algorithms to improve the efficiency of WIM equipped weigh stations.
This research evaluates weigh station design and operational parameters using queueing theory and found that WIM technology not only enhances the effectiveness and efficiency of weigh station operations but also largely reduces travel delay for trucking companies. The effects of truck demand, truck weight distribution, static scale service time, WIM accuracy, and sorting threshold on weigh station operations have been analyzed. The author shows the importance of transponders in a WIM mainline weigh station operation. The author also proves that the increase of storage spaces within a weigh station may largely increase truck travel delay and does not significantly improve weigh station operations.
This research focuses on the development of floating-threshold algorithms. Since the number of trucks, particularly heavy trucks, has increased rapidly in recent decades, many weigh stations cannot meet the demand even when equipped with WIM systems. This problem is complicated by the fact that truck demands, truck weight distribution, and static scale service time vary by time of day and day of week. The author designed floating-threshold algorithms to automatically adapt to high truck demand and the varying of truck demand, truck weight distribution, and static scale service time, over time. When the queue at the weigh station is long, the threshold value is increased so as to avoid the closure of the weigh station while still catching the worst weight limit offenders. When the queue is short, the threshold value is lowered to increase the number of trucks inspected. Both the traditional fixed-threshold strategy and two floating-threshold strategies were modeled and tested using a microscopic simulation model. The results show that floating-threshold strategies are both more effective in weight enforcement and more efficient for heavy traffic flow and high-variance environments. The finding that different floating-threshold strategies have different effects indicates that it is necessary to make a further study on floating-threshold algorithms
The Impact of Tourism on Curacao's Economy: A Scenario Approach
No full textCuraçao is an autonomous countrywithin the Kingdom of the Netherlands. The governmentwants to support tourism development. However,various development strategies are possible. This articlepresents four scenarios of marketing and investmentstrategies that will affect the number of tourists fromThe Netherlands and North America (USA and Canada)in different ways. A multiplier model was used to calculatethe economic impacts of the four scenarios. Bydoing so, this article shows how the government’s decisionto support particular marketing and investmentstrategies may have certain outcomes for the number ofjobs in Curaçao’s tourism industry
Model Validation and New Water Control Strategies in Drinking Water Treatment Plant Wim Mensink
No full textStimela is an environment for standardized mathematical models of drinking water treatment processes. It can be used to predict the future water treatment situation which may happen or change. In water treatment plant Wim Mensink, the Stimela model train was set up to compare with other alternative water control strategies. Before starting the work of developing new water control strategies with Stimela model, Stimela model for Wim Mensink must be validated so that the model can be seen as a reliable and stable tool for the next work. Before the validation work, the current water control strategy for the treatment process needs to be investigated clearly to fulfil all the input control information is correct. Besides this, an experiment for obtaining the measured results of pellet diameters over different layers was performed in Wim Mensink. The validation work starts with single pellet softening process for three different reactors over first month from January 20th to February 20th. The fluidized bed height, pressure drop over total height of reactor, pellet diameters and porosities are validated. After that, the validation work is integrated with whole water treatment system to prove the function of pellet softening reactor and the four important water quality parameters over two important locations (after weir aerator location and final RO mixing location). The validated results of softening process are analysed by the relative error way to prove the reliability of the model results compared with measured results. The final step of the thesis work is developing the new water control strategies to optimize the current control plans of Wim Mensink. Five different water control strategies are put forward. They can be either reached separately according to their own advantages and limitations or fulfil with a step by step order as a whole optimization process. Moreover, the other water control strategies developed by engineering consultancy company DHV are evaluated here with Stimela model so that they can be proved reliable and achievable. In the future, the application of Stimela model will be spread over all the drinking water treatment plants in the Netherlands and contributes to the central automated control as a drinking water treatment operator training simulator.Sanitary EngineeringWatermanagementCivil Engineering and Geoscience
Too good to be true? European hopes for neutrality before 1914
No full textAs the renowned historian, C. V. Wedgwood, famously wrote in her biography of William the Silent, “history is lived forward but it is written in retrospect. We know the end before we consider the beginning and we can never wholly recapture what it was to know the beginning only.” 2 h is is, of course, a warning to historians that any attempt at being ‘true’ to the past is a l awed exercise. It is a particularly apt warning, however, when we assess the writing of the history of nineteenth-century European neutrality, which is ot en imbued with the foreknowledge of the havoc that the First and Second World Wars would wreak. h e First World War is acknowledged as the event that witnessed the decline of the viability and relevance of neutrality and the Second World War as the conl ict that killed the traditional idea of neutrality of completely.
Use of Axle Load Spectra (ALS) for Estimating Calibration Drift in Weigh-In-Motion (WIM) Systems
No full textThis analysis's main objective is to determine WIM system errors based on axle loading without physically performing WIM equipment performance validation using test trucks. The presented methodology can be used to estimate systematic errors (calibration drift) in the WIM system at any point in time after the equipment calibration. This approach can help highway agencies select optimum timings for routine maintenance and calibration of WIM equipment without compromising its accuracy. The results show that the WIM accuracy for the single axle (SA) and tandem axle (TA) can be estimated with SA and TA NALS shape factors with an acceptable degree of error for bending plate (BP) and quartz piezo QP) sensors. The application and significance of the developed models were explained with the help of an example. The use of NALS to estimate the WIM system accuracy can save a significant amount of time and resources required for field validation of WIM performance every year.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.
