Axisymmetric mirrors have no collision free radial transport, but such magnetic fields may have problems with plasma stability (the tearing instability in particular). There are some means to improve plasma stability in axisymmetric mirrors by magnetic expander tanks or axisymmetric divertors, but plasma stability can still be a challenge in axisymmetric mirrors. An alternative is to use quadrupolar magnetic fields as a robust method to overcome the stability issues. A price may then be increased radial transport if the magnetic field design is done without strict consideration of asymmetries, which could result from manufacturing errors.The computations have been done with a hybrid reactor scenario in mind. Such a case have less demands for confinement, but the demands are still challenging. Confinement for about 200 longitudinal bounces is required in a hybrid reactor. The computations carried out here have confirmed that axial asymmetry may become dangerous for plasma confinement in quadrupolar mirror machines. Asymmetry in the range of a few percentage relative error will almost surely result in a too strong radial leakage (at least without a radial electric field). The computational results made in this paper may suggest that if the manufacturing error is kept below 0.15% relative error throughout the plasma confinement region, there is then a some margin for sufficient radial confinement quality. Such accuracies ought to be possible to achieve in the manufacturing process, possible combined with compensating magnetic fields to maintain a precise magnetic field design. The precision requirements in the design is still a bit challenging.

The study describes design of completed store called " Centrum" in the center of Brno. The study is to design new functional use of the building and a new , contemporary building envelope solutions . Concept of territory is located in the historical center of Brno, Brno- center . The area consists of the original concept of the central city. Buildings with dominant feature of the area of housing and for administration, public facilities and commercial activities . The department store is located between the streets and Jánská Kobližná , close Malinovského square and is shaped as an isosceles trapezoid of parallel sides measuring 23.8 and 12.2 m and a length of 42.2 m Number of floors increase from the original eight floors to thirteen. Novadays, the existing building is used as a trading house , newly designed functional use of a shopping arcade (in the current portion ) of leasable space for offices and housing units ( in the proposed completion ) . In the stalls and streets Jánská Kobližná are situated trading units accessible from a four-storey shopping mall , which house fulfills the growing demand for retail space in the center of Brno . Above the shopping galleries are four separate functional administrative units with a separate entrance from the street Kobližná that are partially recessive separated floor where the observation restaurant . Last four floors contain extra housing units.

The main topic of this diploma thesis is revitalization of the garden, which is a part of the new established Autonomous Social Centre Klinika. It is located in Prague 3 in the Žižkov district and it was established at the end of 2014. Despite the complicated beginnings on the start of existing, this place is important for the life of many people now. The building of the clinic was used for pulmonary disease in the past, but after that it was closed and abandoned for many years. After the time homeless and drug people from Žižkov began to settle here, so the clinic has become a place which is better to go around. It was one of the many cases abandoned buildings from our cities. Abandoned buildings and areas that lose their function are referred as a Brownfields now. Brownfields are the second main topic of this thesis. There were worked with the theoretical part as well in the practice part. Practice part was focused on the case study of the Autonomous Social Centre Klinika. In the theoretical part of this thesis were described how brownfields are created, how we can divide them and how can be treated. It is also describes their influence on the public space and the life of inhabitants. Next there are some examples of brownfields which gained a new function and return to urban life. These projects could be a model for the Klinika Centre. There are mainly projects of community, social and cultural centres in the Czech Republic and also in the world. In the practical part of the diploma thesis was created new design of the outdoor space of the Klinika garden. The garden was designed for all people with different ages, but the main target group is primary those interested in ecology, gardening, culture and art. The proposal shows details of community beds, space around the outdoor café with a natural lecture hall. In general there were supported activities based on meeting new people and develop relationships.

Forskningsfrågor: Fråga 1: Hur ser den nuvarande citylogistiksituationen i Växjö ut och vilka aktörer är involverade? Fråga 2: Vilka problem som kan försvåra införande och drift av ett LMT-system i Växjö kan identifieras bland involverade aktörer?  Fråga 3: Hur kan de problem som försvårar införande och drift av ett LMT-system i Växjö hanteras? Syfte: Syftet med arbetet är att redogöra för de åtgärder som kan utföras för att underlätta införande och drift av ett LMT-system i Växjö. Metod: Studien genomfördes som en kvalitativ intervjustudie med deduktiv inriktning som genomsyrades av ett kritiskt realistiskt synsätt. Den empiriska datainsamlingen tog form genom sex semistrukturerade intervjuer och en ostrukturerad intervju där Växjö kommun, butiker, en fastighetsägare, Växjö Citysamverkan och en tredjepartslogistiker från Växjö intervjuades. Slutsats: Resultat forskningsfråga 1: Växjös stadskärna är inte optimerad för godstransporter och många av de intervjuade respondenterna upplever att detta leder till mycket stadstrafik. Åtgärder har implementerats från kommunens sida i ett försök att minska godstrafiken i centrum. De primära aktörerna som påverkar citylogistiken är butikerna, kommunen, koncern/huvudkontor, transportörer och leverantörer. Sekundära aktörer är fastighetsägare, Citysamverkan och Cityföreningen.2 Resultat forskningsfråga 2: De problemen som bör beaktas vid införande och drift av ett LMT-system för Växjö stadskärna är framförallt finansieringsproblematik, problem kring initiativtagande, bristande kunskapsspridande, otillräckligt samarbete, otillräckligt hög efterfrågan och motståndet kring att betala högre kostnader för transporter. Resultat forskningsfråga 3: Till många av de identifierade problemen i studien existerar konkreta lösningar men det finns samtidigt problem som saknar lösning. Anledningen till att vissa lösningsförslag saknas beror på att problemen som ska lösas är komplexa och är tidskrävande att undersöka, vidare forskning behövs. De främsta lösningarna är åtgärder i form av nya regler för godstrafik, utvidgning av LMT-systemet från stadskärnan, avlastningsplatser/förråd som möjliggör nattlossning, värdeadderande aktiviteter för att öka lönsamheten, privat ägande efter upphandling, EU-/statliga bidrag som finansiering och ett ökat samarbete mellan alla aktörer i form av möten alternativt i form av regleringar som leder till att aktörer måste samarbeta.
