Sandby borg : En komparativ studie av Ölands folkvandringstida befästningsanläggningarGustavsson, Petter January 2014 (has links)
This essay is a comparative study on Migration period ring forts, centered on Sandbyborg, a ringfort situated on the southeastern shore of the Baltic island of Öland.Furthermore this essay focuses on the contemporary Iron Age society, and thestrategical implications of the ringforts in their function as fortifications. Certaininternational comparisons are made, in particular regarding the fortifications in theRoman empire.

Försvarsmaktens infrastrukturprocess : En kvalitativ studie i beslutsfattandeGreen, Matias, Törnqvist, Mats January 2019 (has links)
Försvarsmakten lägger varje år ca 5 % av sin budget på infrastruktur, alltså kostnader för mark, anläggningar och lokaler. Infrastruktur är till sin natur mycket långsiktigt: tar lång tid att skapa och används under ännu längre tid, idealt längre än femtio år. När något väl är byggt är det både kostsamt och tidskrävande att ändra på detta. Detta gör att beslut avseende infrastruktur behöver vara väl underbyggda och avvägda för att ekonomiska medel ska användas på ett så bra och effektivt sätt som möjligt. Denna studie har undersökt beslutsfattande angående infrastruktur inom Försvarsmakten.Studien har genomförts med en induktiv kvalitativ ansats där vi intervjuat ett antal personer inom Försvarsmakten som arbetar med infrastruktur, antingen som huvuduppgift eller som deluppgift. Personerna är handläggare snarare än beslutsfattare, på central nivå inom olika funktioner. Under intervjuerna har vi sökt de intervjuades syn på beslutsfattande avseende infrastruktur.Vi har funnit att beslutsfattandet påverkas av ett antal faktorer: sökande efter eget ansvar och mandat samt efter vem som har ansvar och mandat att fatta beslut, vissa skillnader eller motsättningar mellan handläggning på central och central gemensam nivå, en obenägenhet att ta risker, sökande efter prioriteringar, en upplevd personalbrist, samt ett handläggande som sker i isolerade funktioner eller stuprör. / The Swedish Armed Forces annually allocates approximately 5 % of its budget for military infrastructure, i.e. costs for land, fortifications and buildings. Infrastructure is by its nature very long term: it takes time to construct, and the construction is to be in use for an even longer period of time, ideally more than fifty years. By the time the construction is complete it is both costly and time consuming to make changes. The effect of this is that decisions concerning infrastructure needs to be well founded for the financial resources to be used as efficiently as possible. This study has looked into the decision making concerning infrastructure within the Swedish Armed Forces.The study was made using an inductive qualitative approach using interviews of a number of armed forces officers working in connection with infrastructure, either as a main task or as a part time task. The persons being interviewed are staff officers, or managers, rather than decision makers, centrally placed within the Headquarters of the armed forces. During the interviews we have sought the interviewees own views of decision making concerning infrastructure.We have found that the decision making is affected by a number of factors: a search for one’s responsibility and mandate and who has the responsibility and mandate, differences and conflicts between managing in different functions, a reluctance to take risks, a search for prioritizations, a perceived lack of manpower, and a managing within isolated functions.

Brandpåverkan på skyddskonstruktioner i funktionsskyddsrum : En undersökning av resthållfasthet i betongbalkarMalmros, Catrine, Andrea, Johnson January 2018 (has links)
In the beginning of the 21st century decisions were made regarding the decommission of the total defence in Sweden. Since then the security policy situation has changed, regarding both the risk of war and other types of treats such as terrorism. Due to this the total defence is now being re-established. The Swedish Fortifications Agency and Research Institutes of Sweden (RISE) has initiated the Centre of excellence for fortification (CFORT) to support the development of competence in fortification. In case of a crisis or war secured function shelters constitutes a significant part of the Swedish total defence by protecting important technology and activity.The purpose of this bachelor thesis is to investigate the remaining load bearing capacity in concrete constructions in secured function shelters after exposure to fire. This will provide a foundation for further research within the area of the effects of fire in secured function shelters. To achive this, experiments were conducted on nine concrete beams which were casted according to calculations based on the structural codes of the Swedish Fortifications Agency (FKR). Since fully scaled beams are difficult to manage and would not fit in the equipment being used, the beams were casted in a smaller size; 2000 x 150 x 210 mm. Samples of the concrete and the reinforcement were sent to the Swedish Cement and Concrete Research Institute (CBI) for tests which provided actual values of the compressive strength, yield point and modulus of elasticity. Six of the beams were in pairs exposed to fire in a specially built oven according to three different temperature curves. All the beams were later subjected to load until failure. Calculations regarding load bearing capacity were executed with both theoretical and actual values obtained from CBI. The results were compared to the results from the loading tests. During the last fire experiment the beams spalled, most likely due to the quickly rising temperature. The loading test showed that the strength of the beams which had not spalled were not significantly lower than the unaffected beams. Those beams showed a reduction of only 0 – 6 %. However, the beams which had spalled showed a reduce in strength of approximately 20 %. / Centrum för fortifikatorisk kompentens
