Utsikt mot havet : Mot en förändrad förståelse av mellanneolitikums kultur- och samhällsliv i östra Mellansverige

Samuelsson, Erik January 2023 (has links)
Abstract  Erik Samuelsson: A View Towards the Sea – Towards a Changed Understanding of the Culture and Social Life of the Middle Neolithic in Eastern Central Sweden.  The objective of this essay is to undertake an investigation and critical review of the Neolithic cultural groups as defined by contemporary archaeologists. This will be achieved through the analysis of empirical material derived from the Neolithic site of Tibble, located in the Björklinge parish of Uppland, Sweden. The primary aim is to develop a more comprehensive understanding and interpretation of not only the specific site but also the cultural and social aspects of the Neolithic period as a whole. Key questions addressed in this study include the impact of material studies on the overall interpretation of Neolithic culture and social life, as well as the potential for attaining a more holistic understanding of a time and place through an analytical approach that oscillates between detailed analysis and broader contextual perspectives. The primary sources utilized in this research consist of material artifacts, reports, and relevant literature pertaining to the Middle Neolithic settlement at Tibble, Björklinge parish, Uppland, Sweden. The theoretical framework employed in this study, as well as the chosen methodology, is rooted in the hermeneutic spiral. Previous investigations into the Stone Age have been largely characterized by the classification of cultural groups, with limited consideration given to the criticism of the concept of culture itself. Consequently, substantial changes in the interpretation of the Neolithic period and its inhabitants have not been extensively pursued. In this essay, the integration of hermeneutics and interdisciplinary approaches is demonstrated as a valuable means to foster a transformative understanding of both specific sites and broader chronological periods. By doing so, it becomes possible to harness the knowledge embedded in material studies.It is important to note that this essay does not aspire to provide an ultimate solution to the perceived problem but rather represents an initial step towards a new direction of inquiry. This process is not necessarily confined to a singular location or region but can be applied to the interpretative work concerning other Neolithic sites as well.

Vems villkor vinner? : Kolliderande standardavtal i förhållande till avtalsrättsliga utvecklingslinjer / Whose Terms will Prevail? : Battle of Forms in Relation to Patterns of Development in Contract Law

Ringstedt, Viking January 2022 (has links)
The basis of any contract is the agreement of two or more parties. In traditional Swedish and English contract law theory, a contract is formed through the reciprocal exchange of an offer and a corresponding acceptance. Together, these declarations of will represent the common intent of the parties, which binds them to their respective contractual obligations and determines the contents of the contract. In the contemporary commercial sector, the use of standard forms (i.e., sets of terms that have not been individually negotiated) has become more prevalent. This has led to the rise of a particular legal issue, called the “battle of forms”: a situation where both parties refer to their own, conflicting, standard forms during the formation of contract, where after they proceed in fulfilling their contractual obligations. Consequently, the exchanged declarations of will lack conformity in these cases, and there is no discernible common will of the parties. In order to conclude that a contract has been formed, and to decide its contents, this conflict needs to be resolved. The traditional approach to resolving the issue of battle of forms in English law is to regard the last referenced standard terms in the contractual negotiations as an offer (or counter-offer), and the other party’s conduct as an acceptance. This approach largely corresponds with how the issue likely would be resolved according to traditional Swedish contract law principles. However, in the legal scientific environments of both Sweden and England, ideas and concepts of a modern contract law has developed. Included therein is the idea of taking a more flexible stance with regard to the formation of contract. When viewing the contractual relationship holistically, and partly liberated from the offer-acceptance approach, the battle of forms can be resolved by letting the court construe the different sets of terms together, and re-place conflicting terms with suitable substitutes by implication. These modern concepts have partly manifested in recent English precedence regarding the battle of forms. Considering that the patterns of development with respect to the modern law of contract are similar in Swedish and English law, there is reason to believe that a similar “new” approach to the battle of forms might be adopted by Swedish courts as well.

Турки и турецкая угроза середины XV в. в восприятии византийских и восточно-европейских авторов : магистерская диссертация / The Turks and Turkish Threat in the middle of the Fifteen Century in the Perception of the Byzantine and East-European authors

Zhigalova, N. E., Жигалова, Н. Э. January 2014 (has links)
The dissertation is devoted to the problems of the perception of Muslims and the threat posed by the Ottoman by the Byzantine and East-European writers of the XV century. According to the materials of historical works analyzed the ratio of the authors to the representatives of the Islamic faith in a severe foreign situation and also domestic religious contradictions. Analysis of the works of Byzantine and Balkan writers allows us to trace the evolution of the views of historians on the matter and to reveal the extent of their bias. According to the Byzantine and East-European sources revealed the attitude of the authors of the XV century to the Turks and denoted points of contact of Christian and Muslim civilizations in the context of military confrontation, also investigated the attitude of the authors to the key events of the Turkish expansion in the XV century - Battle of Varna in 1444 and the capture of Constantinople in 1453. The dissertation also addresses the problem of mutual Christians and Muslims considered in the interpretation of the writers and the question of the possibility of cultural and religious dialogue between the warring parties. / Диссертация посвящена рассмотрению проблемы восприятия мусульман и угрозы со стороны османов византийскими и восточно-европейскими писателями XV века. По материалам их исторических произведений анализируется отношение авторов к представителям исламского вероучения в условиях тяжелой внешнеполитической ситуации и внутренних религиозных противоречий. Анализ сочинений византийских и балканских писателей позволяет проследить эволюцию взглядов историков относительно данного вопроса и выявить степень их тенденциозности. По данным византийских и восточно-европейских источников выявляется отношение авторов XV в. к туркам, обозначаются точки соприкосновения христианской и мусульманской цивилизаций в контексте военного противостояния, а также исследуется отношение авторов к ключевым событиям турецкой экспансии XV в. - битве при Варне 1444 г. и захвату Константинополя в 1453 г. В диссертации также затрагивается проблема взаимовосприятия христиан и мусульман в интерпретации рассматриваемых писателей и ставится вопрос о возможности культурного и религиозного диалога между представителями противоборствующих сторон.

Modeling and Evaluation of Turret Control Systems for Main Battle Tanks

Lyth, Mikael January 2021 (has links)
The aim of the thesis was to implement and compare control methods in a model of a main battle tank. Three controllers were implemented in a two axis gimbal model and their performances were compared. The comparisons were performed using step changes in the reference signal, frequency analysis of an oscillating reference signal and disturbances, and turret mass uncertainties. The results showed that the sliding mode controller had the best performance for both reference changes and disturbance attenuation. The PID controller had a better performance for the change in reference, compared to the model predictive controller, but a significantly worse disturbance attenuation. Due to model approximations, such as assuming ideal engines and noise reduction, the results likely show a better performance than what can be expected if applied on a real main battle tank. Therefore, the results show an upper limit of the stabilization performance of turret and barrel control and should only be used to compare the controllers. / Målet med uppsatsen var att implementera och jämföra reglermetoder för en teoretisk modell av en modern stridsvagn. Tre metoder implementerades i ett tvåaxligt gimbalsystem och deras prestanda utvärderades. Mer specifikt utvärderades regulatorernas respons för en referensändring, en referensstörning och osäkerheter i tornets massa och massfördelning. Utifrån dessa resultat jämfördes sedan reglermetoderna. Resultaten visade att sliding mode regulatorn hade bäst prestanda för både referensändring och referensstörningen när man tittar på frekvensanalys av mät- och processstörningar. PID-regulatorn hade en bättre prestanda än MPC-regulatorn för en referensändring men en sämre respons för en referensstö-rning. På grund av modellförenklingar som till exempel antaganden om ideala motorer och brusreduktion visar resultaten troligen en något bättre prestanda än vad som kan uppnås på en riktigt stridsvagn. Det medför att resultaten visar en övre gräns för vad styrsystemet för en stridsvagns torn- och eldrörsrotation kan uppnå.

Participatory design for battlefield park development and process comparison

Lowe, Steven Michael 11 June 2009 (has links)
The Shenandoah Valley Civil War Sites Study Act of 1990 permitted the National Park Service (NPS) to investigate which unprotected battlefields (I5) might be preserved. After collaboration with the NPS, I was allowed to research the battlefield site of Opequon Creek (Third Battle of Winchester) in Frederick County, Virginia. In return, the NPS would receive a copy of this thesis for their use. A questionnaire, submitted to local residents, determined if a park was wanted, what type of park it might be, and what programming activities would be selected. A combination park of recreation, historical, and natural definitions was developed on the residents desires. The Opequon Creek Park process was developed first to alleviate any pre-NPS planning process influences. After Opequon Creek Park was designed, a process comparative analysis was made with the existing NPS model of Antietam Battlefield Park located in Sharpsburg, Maryland. The analysis determined if the NPS's planning process needed refinement. The NPS uses the "Planning Process Guidelines, NPS-2, 1985", to create each park's General Management plan (GMP). Two participatory stages, open houses and public hearings, were found mid-way through the development of Antietam's GMP. The Opequon process allows for participatory input at the start of park development but, did not allow for post design comments. Antietam's park definition was determined before public input was solicited and used based on early project funding requirements. The Opequon process, if implemented immediately upon a new parks legal creation, would save the NPS time and money in the research and development of new parks. Future parks will be carved from urbana as America's population doubles by 2038. The NPS needs a refined participatory planning method to do business with the public of today, the shrinking budgets of tomorrow, and the preservation of needed green space in the future. / Master of Landscape Architecture

Krigföringens principer : Fina ord eller nyttiga lärdomar? En teoriprövande studie av Marvin Pokrants krigföringsprinciper

Åkerström, Andreas January 2024 (has links)
The Principles of War have long been debated about their relevance and usefulness within the military context. Some theorists think that the Principles of War are laws that should be followed to achieve success in battle, while others see them more as guidelines. The principles have also been discussed on which level and type of warfare they should apply on, furthermore which types of principles to include. A theorist that has published a revised set of nine principles is Marvin Pokrant (2021), these Principles of War aim to be relevant across all levels and types of warfare. They are also one of the most contemporary sets of principles and has not yet been tested. Therefore, are the purpose of this study to both contribute to the overall research about the principles of war and more specifically if Pokrant’s (2021) set of principles has any explanatory value about success in modern military operations. The result of this study shows that this set of principles has explanatory value about the success in modern military operations. This is because the successful case had eight out of nine principles present, while the unsuccessful case only had two.

Vít MIŠAGA, Christian IV, Mansfeld and the Invasion of Silesia and Moravia. Several Aspects of the Danish Phase of the Thirty Years' War, PhD dissertation, Charles University in Prague 2014 Summary In Czech and European historiography of the early modern period, the Thirty Years' War (1618-1648) is one of the most discussed topics. Among Czech historians, there has always been an understandable emphasis on the revolt of the Bohemian estates, also known as the Bohemian phase of the war (1618- 1621). The Danish phase (1625-1629) is considerably less popular. The winners had already been or - to be more precise - seemed to be almost determined, and the further developments of the war did nothing to change the fate of the Czech lands. Analysis of the second half of the 1620s is therefore dominated by other topics - the recatholisation process, exile waves or the character of Albrecht von Wallenstein. Foreign historiographers also seem to downplay Denmark's influence. It is as if King Christian's unsuccessful attempt to fight the Emperor was only biding everyone's time until the "Lion of the North", Gustav II Adolf of Sweden, makes his great entrance. Or at least that is the perspective of an "all-knowing" historian who already knows the result. This thesis is trying to bring a different perspective. It is based...

Sidi Rezegh and Tobruk : two South African military disasters revisited 1941-1942

Katz, David Brock 12 1900 (has links)
Thesis (MMil)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Sidi Rezegh and Tobruk are the largest disasters suffered by South Africa in its military history. Yet, despite their enormity, Sidi Rezegh and Tobruk are little understood and hardly remembered. South Africa declared war on Germany on the 6 September 1939, after a bitter internal debate, amounting to a conflict between Afrikaner nationalists and those who supported the British Empire. South Africa’s political ambivalence and disunity ran parallel to her unpreparedness for war in every important department from the lack of vital coastal defences to the miniscule size of her army and air force and complete lack of a navy. The first six months of 1941 saw the South Africans play a significant part in completely defeating the Italian colonial forces in East Africa. However, the campaign was poor preparation for what the South Africans were to encounter in the North African Desert months later. South African troops spent their time rebuilding fortifications in Egypt rather than in essential training to acclimatise this “bush war” army to harsh desert conditions. In a reluctant political decision, the unprepared South Africans were committed to Operation Crusader. The inexperienced South Africans met up with the battle hardened Afrika Korps at Sidi Rezegh on 23 November 1941 and were annihilated in the face of overwhelming odds. In revisiting this forgotten battle, it has been found, using primary and secondary sources, that the South Africans extracted an enormous price on the German armour in what may have been the true turning point of Operation Crusader. In May 1942, Rommel’s Afrika Korps sallied forth in a series of lightning moves that demonstrated the Axis grip on combined operations and managed to isolate the vital port of Tobruk commanded by an inexperienced South African, Major General H. B. Klopper. His surrender in one day is often compared to the previous siege endured under similar circumstances, where the Australians managed to hold Rommel at bay for 244 days until the siege was lifted. Klopper’s surrender of Tobruk resulted in a political crisis for Winston Churchill and for Jan Smuts, as the fiasco caused considerable tension within the Allied camp and within South Africa. On re-examination, interesting facts have emerged from the primary source material, as to the state of the Tobruk defences and of its unfortunate commander and how the United Kingdom, acting in concert with South Africa, sought to suppress the true facts. Immediate post-war memory has been shaped and distorted by sensitive political considerations that affected relations between South Africa and the United Kingdom. Thereafter, the memory of Sidi Rezegh and Tobruk was relegated first by a nationalistic Afrikaner government and then since by a democratically elected government, both of which have seen very little use in incorporating these two milestones into the national memory. / AFRIKAANSE OPSOMMING: Sidi Rezegh en Tobruk is die grootste nederlae wat Suid-Afrika in sy militêre geskiedenis ervaar het. Ten spyte van hul omvang, word daar min van Sidi Rezegh en Tobruk verstaan of onthou. Na ‘n hewige interne debat wat tot konflik tussen Afrikanernasionaliste en pro-Britse Suid-Afrikaners gelei het, het Suid-Afrika op 6 September 1939 oorlog teen Duitsland verklaar. Suid-Afrika se politieke verdeeldheid het saamgeval met die Unie se totale onvoorbereidheid vir oorlog, wat gestrek het van kritieke tekortkominge in kusverdediging, tot die ontoereikende grootte van die leër en lugmag en die totale afwesigheid van ‘n vloot. Gedurende die eerste ses maande van 1941 het Suid-Afrika ‘n beduidende rol gespeel om die Italiaanse koloniale magte in Oos-Afrika te verslaan. Dié veldtog was egter nie effektiewe voorbereiding vir die uitdagings waarteen die Suid-Afrikaners kort daarna in Noord-Afrika te staan sou kom nie. Die Suid-Afrikaanse troepe het daarby hul tyd daaraan bestee om vestings in Egipte te herbou in plaas daarvan om noodsaaklike opleiding te ondergaan om hul “bosoorlog”-leër vir ruwe woestynoorlogvoering voor te berei. ‘n Huiwerige, teensinnige politieke besluit het die onvoorbereide Suid-Afrikaners tot Operasie Crusader verbind. Die onervare Suid-Afrikaners het op 23 November 1941 by Sidi Rezegh teen die geharde Afrika Korps te staan gekom, waar oorweldigende magte hulle verpletter het. ‘n Heroorweging van hierdie vergete veldslag aan die hand van primêre en sekondêre bronne het aan die lig gebring dat die Suid-Afrikaners ‘n hoë tol van die Duitse pantser geëis het, wat besmoontlik die ware keerpunt in Operasie Crusader gebring het. In Mei 1942 het Rommel se Afrika Korps deur ‘n reeks blitsige bewegings wat die greep van die Spilmagte op gekombineerde operasies gedemonstreer het, daarin geslaag om die kritiese hawe van Tobruk, waar die onervare Suid Afrikaanse generaal-majoor H.B. Klopper in bevel was, te isoleer. Sy oorgawe binne ‘n enkele dag word dikwels vergelyk met die vorige beleg van Tobruk toe die Australianers Rommel onder vergelykbare omstandighede vir 244 dae teruggehou het totdat die beleg opgehef is. Klopper se oorgawe het ‘n politieke krisis vir Winston Churchill en Jan Smuts geskep, deurdat dit aansienlike spanning binne sowel die Gealieerde kamp as Suid-Afrika veroorsaak het. Die herevaluering van die gebeure het interessante feite uit die primêre bronne na vore gebring ten opsigte van die toestand van Tobruk se verdedigingstellings, die ongelukkige bevelvoerder, en hoe die Verenigde Koninkryk in samewerking met Suid-Afrika die ware feite wou toesmeer. Die onmiddellike naoorlogse geheuebeeld van die gebeure by Sidi Rezegh en Tobruk is geskep en verwring deur sensitiewe politieke oorwegings wat die verhouding tussen Suid-Afrika en die Verenigde Koninkryk beïnvloed het. Sedertdien het ‘n nasionalistiese Afrikaner-regering en daarna ook die demokraties-verkose, post-apartheid-regering die herinneringe aan Sidi Rezegh en Tobruk tot die vergetelheid verdoem; nie een van die twee het die nut daarvan gesien om dié twee mylpale in die nasionale geheue te verewig nie.

Latinskoamerická emancipace v kontextu mezinárodní velmocenské politiky v letech 1815-1826 / Latin American Emancipation in the Context of International Great Powers Policy in the Years 1815-1826

Hertel, Petr January 2011 (has links)
This work, the way its name suggests it, is intent on the theme of process of achievement of the Latin American states' independence of Spain and Portugal, and on situating of this process in the context of the events of this time in further world's parts, and mainly in the context of the policies of single powers which had, or could have, some interests in the said spaces. Likewise the name itself suggests, its chief interest is intent primarily on the period of the years 1815-1826. While in Europe the Napoleonic Wars had definitively ended, and a new order here was creating, according to principles of the Vienna Congress, and under the supervision of the Holy Alliance, Spanish America had gone through first phase of her own wars of liberation, and it could seem, on the beginning, the situation here was coming anew to profit of the Spanish monarchy, recuperating from the precedent years of the French rule and the war with French intruders. However, the struggle of independence of single Hispanic-American states was continuing, like the Portuguese Brazil reached for own independence of colonial metropolis as well. In the Spanish America's case, Spain, really isolated, despite the negative attitudes of the Holy Alliance's monarchical governments towards the development in her oversea possessions, and...
