The contents are accesible to all who have some knowledge in numerical mathematics and third year bachelor physics. I will start this thesis by introducing the problem and the experiment which led to the problem, this will be done in section 1 and 2. In section 3 I will show the models used for simulating the experiment. Section 4 will be about the numerical method I used. I will show and discuss the results from the calculations in section 5, 6 and 7. I want to thank Barry Koren, for his enthusiasm on this subject which was also new to him. In addition I want to thank him for his excellent guidance in the traject of the bachelor project and introducing me at the CWI. I also want to thank Tjerk Oosterkamp for introducing me to this subject and for never being out of enthusiasm and useful ideas. At last I want to thank Bas Edixhoven for introducing me to Pari/GP and for his different view on the mathematical part of the problem.Show less

We suggest a more reliable method for solving non-linear systems of equations that is based on numerical methods for solving differential equations, and show, given the physical nature of the model, that it will find a solution more reliably. This new method is called the Taylored Backward Euler method. It is very reliable, but takes more time to find a solution than the Newton-Raphson algorithm.Show less

On the basis of the problem definition an answer is sought for the question whether the bone paste was inserted into the pottery decorations and what this bone paste is made of. This question is answered through four research parts. The first is a study of Funnel Beaker pottery to look at how frequently the phenomenon of bone paste usage occurs. The second is an experiment to try to find out what is the best way to make bone paste. The third is a taphonomical experiment to see if there are any detectable traces of the application of bone paste in the pottery. And the fourth is a DNA analysis to find out if the bone which was used for the Funnel Beaker pottery was human or animal derived. The conclusion of this thesis is that bone paste can be found in about 23% of the ancient pottery studied. Probably, more pottery contained bone paste, but this is undetectable due to taphonomic conditions and the cleaning of the pottery. White burned crushed bone was most likely rubbed into fired pottery and then a fatty substance such as melted butter was put over it. This means that the pots could not be heated or washed. The result of the taphonomical part of the research is the discovery that bone powder applied before melted butter is most resistant to all kinds of taphonomical processes. The outcome of the DNA analysis is that most likely burned human bone was used as a source for the crushed bone powder in the ancient pottery decorations.Show less

In 2008 ‘Veilingterrein’, an area adjoining the former port area, was excavated. Among the finds were 50 water wells. For this study two of these wells were investigated at the Cultural Heritage Agency (lab Stichting RING/RCE). One water well was made of a discarded cask made of 23 oak staves and a piece of beech. Samples were taken from the staves and the tree rings measured. The staves were found to originate from one single tree. Synchronising the data from all staves created a series of 111 tree rings, including 11sapwood rings. This series did not match reliably with the reference chronologies. Cross-dating individual staves with the chronologies was not successful either. The piece of beech could not be dated dendrochronologically. The second water-well, a hollowed-out oak, was sampled, the synchronised measurements totalled 92 rings, no sapwood was present. The wood did not match with the reference chronologies.Show less

Rock art is een geschikt medium voor een bredere studie naar de prehistorische samenleving en de bewoning en het gebruik van het landschap. De regio Bohuslän in Zweden is als onderzoeksgebied gekozen daar er zich een grote concentratie rock art bevindt en er zeer gedetailleerde, recente onderzoeken beschikbaar zijn. Het rock art onderzoek in Bohuslän is van oudsher, maar zelfs tot op de dag van vandaag, geregeerd door het aardse paradigma. De laatste jaren is er een begin gemaakt met het vestigen van een nieuw maritiem kader. De meest voorkomende figuratieve motieven in Bohuslän zijn petrogliefen van boten. Het lijkt er op dat die op een betekenisvolle locatie aan de kust liggen. Ze wijken sterk af van de rock art uit de omgeving. De grootste rock art sites met de meeste afbeeldingen van boten zijn in de nabijheid van de kust gelokaliseerd, terwijl rock art sites met afbeeldingen van grote mensfiguren zich op de hoger gelegen gebieden bevinden. Zou het om een locatie kunnen gaan waar de lokale elite zijn reizen begon? De onderzoekers zijn het er over eens dat de samenleving in de bronstijd de vorm van een “chiefdom” heeft. Er zijn echter vele verschillende vormen van een “chiefdom”, van sterk hiërarchisch tot meer egalitair. De rock art kan ons een aanwijzing geven over de mate van hiërarchie binnen de “chiefdoms” en daarmee de sociale structuur van de samenleving in Bohuslän.Show less

During the research of the area, it became clear that this place was of great archaeological interest. So it was decided that excavation was necessary. The excavation commenced in spring 1976 and took several years. During the excavation two house plans were identified and great quantities of pottery collected. Unfortunately, there has been no documentation in the thirty years since the excavation with exception of site plans. Therefore there is a great shortage of information. In the past years some students did some thesis-research on the subject of Wijchen-Berendonck and they discovered that this site contained mainly Iron Age material. The houses have been dated to Early and Middle Iron Age as well. In this thesis a small part in the northwest of the site is studied. At this part of the site only two structures are evident: two small barns. The focus of this thesis is on the pottery found in four large pits. The results of this research indicate that the material is from the Iron Age also and so it is suspected that the collection also contains Early and Middle period. However this is not clear enough, which is due to the lack of information and documentation. To achieve more clearance in this project we need to wait for the research results of masterstudent Marloes Luijten, who is studying the rest of the site at the moment.Show less

In order to analyse the relationship of the people who lit the fire with their environment, charcoal determination is conducted in this report. The relevance of charcoal investigation is addressed and for determination, sixteen recent samples were compared with the archeological charcoal and morphological features were looked at. Several approaches towards the choice of wood are noted; not only the suitability, determined by ecophysical and mechanical properties and availibity is looked at, but also ethnographical usage of species is briefly addressed. Concerning the determination, it was established that the species found, Laguncularia racemosa, was present in the vegetation between 1415 and 1648, in which period the archeological charcoal remains were carbon dated.Show less

Stein and Vlaardingen show many similarities in pottery which lead to the suggestion that they might have been one cultural phenomenon, with Stein being the dry component and Vlaardingen the wet component. However, this disregards the differences in other aspects of material culture. The Wartberg-culture is geographically far apart and show some important differences. The main conclusion of this paper is that there is not enough common ground for the Wartberg-Stein-Vlaardingen-complex set apart from other middle and late neolithic cultures in Western Europe. The relations of the Wartberg-culture with Stein- and Vlaardingen-group are not as close as propesed by Louwe Kooijmans (1983).Show less

This compilation consists of data from the Caribbean archaeological record (with the Early Ceramic Age component of the site Morel (300 B.C. – A.D. 400), Guadeloupe, as a case study) and is supported by information from Caribbean ethnohistoric accounts and analogous South American ethnographies. From these multidisciplinary sources it becomes evident that while there are many problems associated with the research focused on dogs within Pre-Columbian Caribbean Archaeology, there are some general conclusions that can be made. Remains or representations of the dog have been found in almost every island of the Caribbean, with the oldest dog remains dating to the Archaic Age. The dog’s presence in the archaeological record becomes significant from the Early Ceramic Age onward, when the first burials and ceramic representations are found. Dogs might have been buried as an offering, out of personal reverence of the animal or as a guide for the souls of the dead. Similar ideas of the dog as a protector and mediator of the border between the worlds of the living and the dead exist in many cultures across the world. There are also several parallels between burials of humans and dogs in both the Caribbean and in Europe. In the Caribbean dogs were also totemic and cultural symbols, whose representations and skeletal or dental elements might have been as important as their burials. From the available evidence it can be concluded that the social role of the dog in the Caribbean probably consisted of the dog as a family member, as well as a (hunting) companion or guide (whether in life or in death). The attention commonly lavished on dogs in mortuary contexts suggests that dogs are about as close to being considered a person as a non-human animal can be.Show less

It is used still today to determine specific proveniences for archaeological objects. A lot of problems tend to occur when trying to determine a provenience for objects in a region where cultural interaction played a major role. These problems contain questions such as whether culture is recognizable through similarities and differences in small details and whether a style is really specific for a certain culture or region. These and other problems are the central theme of this thesis and these are being analysed with the help of a case study. This case study focuses on finding the place of manufacture of the ritual Mesoamerican book called Codex Borgia. The specific questions that stand central in this thesis are: which theories have been created about the origin of the Codex Borgia and how did the researchers interpret data for this research question? Furthermore, does finding a place of manufacture for the Codex Borgia give us new insights for further research in this area? Five of the many theories concerning this topic have been analysed here. It has been concluded that a couple of the researchers have been focussing on style-culture relations which tend to reveal little about a specific place of manufacture. This is due to the fact that similarities in this style, called the Mixteca-Puebla style, have been found over a large region. It is argued in this thesis that on the basis of style alone a specific region or place cannot be identified. That is why it has been argued that other sources should be used as well such as the content of the book. It has also been argued that we should not focus on trying to find a more specific place of manufacture for the Codex Borgia because it would not give us useful information on which further research can be based. We should not look for big differences in cultures as well, especially in a region where cultural interaction is dominant. Rather, we should focus on trying to understand this interaction and how it came to be.Show less

Alhoewel de Caberg geografisch gezien dichterbij de Heeswatercluster ligt, lijkt de Bandkeramische bewoning van de Caberg in verschillende aspecten beter aan te sluiten bij de Bandkeramische bewoning van de Graetheidecluster. De Bandkeramische vindplaatsen van de Caberg worden gedateerd in de fasen 1C t/m 2D, waarbij de nadruk ligt op bewoning in de fasen 1C/1D. De vindplaatsen zijn daarnaast allen slechts één à twee fasen bewoond. Bovendien hebben ze een relatief lage spreiding van sporen. Deze kenmerken gelden ook voor de Bandkeramische vindplaats Maastricht-Belvédère 1988, wat het idee versterkt dat de Bandkeramische bewoning van de Caberg beter past bij de Bandkeramische bewoning van de Graetheidecluster, dan bij die van de Heeswatercluster.Show less

Troje in Noordwest-Anatolie en Poliochni op Lemnos maakten deel uit van deze handelsnetwerken. In deze periode doken er voor het eerst veel fijngemaakte sieraden op, waaronder de 'basket-shaped' oorbellen. Zo zijn er een aantal zeer rijke schatten met 'basket-shaped' oorbellen zowel in Troje als Poliochni gevonden. Deze gouden oorbellen laten een vergevorderde kennis van goudbewerking zien en een beheersing van een grote diversiteit aan technieken. De oorsprong van de vele technieken gebruikt in de 'basket-shaped' oorbellen, en de parallellen die vele objecten uit hun vondst-contexten in de verre omgevingen vinden, geven aan dat de edelsmeedkunst van Troje en Poliochni invloeden van buitenaf kende. Het lijkt echter onwaarschijnlijk dat een rechtstreekse route Troje en Poliochni met Mesopotamie verbond. Hoewel vaak aangenomen wordt dat de 'basket-shaped' oorbellen dit wel suggereren, is de verspreiding van 'basket-shaped' oorbellen juist opvallend beperkt tot de omgeving van Troje, vier voorbeelden uit Eskiyapar, Noordwest-Anatolie, daargelaten. Het is aannemelijk dat Troje en Poliochni in de Vroege Bronstijd deel uitmaakten van een handelsnetwerk dat zich strekte van het Egeische gebied tot aan Mesopotamie (en mogelijk nog verder), echter niet via directe wegen maar door connecties tussen 'handelsgebieden' die elkaar overlapten en onderling aan uitwisseling deden. Zo konden ideeen, grondstoffen en objecten zich over grote afstanden verspreiden. De contacten, die waarschijnlijk al lang bestonden, werden intensiever door de zoektocht naar grondstoffen en technieken bij de intrede van de metallurgie. De locatie van Troje en Poliochni was een belangrijke factor voor het ontstaan van de schatten en de 'basket-shaped' oorbellen daarin. De twee nederzettingen, vooral Troje, hadden niet alleen een goede aansluiting op de belangrijkste handelsroutes van Centraal-Anatolie en maritieme contacten met het Egeische gebied, maar ook contacten over de Zwarte Zee en een goede beschikbaarheid van metalen. Hierdoor kon er in Troje en Poliochni een sociale elite opstaan en een rijke metaalindustrie opbloeien waarin edelsmeden, die zich onder andere door Mesopotamische sieraden lieten inspireren, hun eigen stijl in sieraden konden ontwikkelen.Show less

As these representations are often beyond the control of archaeologists, they run the risk of giving the people an image of the past that is simplified and/or full of speculation. This in turn can lead to (and has led to, both in past and present) political misuse of archaeology. Through a lesser studied case-study in the field of Japanese archaeology, the protohistoric Kofun era and its haniwa clay figurines, this paper aims to create an awareness of how the way we represent our finds influences the identity of a society, both on a small scale and on a national scale, and how we can gauge this influence by looking at a nation's popular culture and art. In this I will focus specifically on the popular representations in archaeological parks and festivals and on how to find the influence of these representations in popular culture and art. As I find out during my research it is certainly possible to see an influence of archaeology in popular culture. Unfortunately the question remains if this is really an influence of the way archaeology is represented, or merely a matter of taste and interest of the artist. One might argue though that if a lot of artists like using these archaeological images this in itself could be a visible influence of the impact of archaeological representations. Either way it appears that more research is needed in this field.Show less

The changes started after the signature of the Pact of Valletta, which should protect the archaeological soil archive in Europe and encourage spreading the knowledge about archaeology to the public. Since 1999 it was possible for commercial archaeological enterprises to obtain a digging license and in 2007 the new monument regulation was implemented in The Netherlands. This was the beginning of a new era for the archaeologists. It means that when developers disturb the archaeological soil archive, they are obligated to pay for the archaeological research. This regulation provided a lot jobs and security for the conservation of the archaeological information and there are several enterprises that are specialized in public archaeology. All benefits, but what does the developer who pays all this feels about it? Five developers were interviewed on the subject and they all say it is a good thing this regulation is implemented and archaeological research has become a part of the process of development. The negative side of archaeological research is that it is unpredictable in terms of money and time. Besides this risk the product of archaeological research is not very useful for the developers. They would like to see more in return for their investment, for example through the media attention. When an archaeological find is published in a paper, they could mention the name of the developers if he cooperates well with the archaeologists. This would provide archaeology with an extra value for the developer.Show less
