Simulated Annealing : implementering mot integrerade analoga kretsar

Today electronics becomes more and more complex and to keep low costs and power consumption, both digital and analog parts are implemented on the same chip. The degree of automization for the digital parts have increased fast and is high, but for the analog parts this has not come through. This have created a big gap between the degrees of automization for the two parts and makes the analog parts the bottleneck in electronics develop. Research is ongoing at Electronics systems group at Linköping University target the increase of design automization for analog circuits. An optimizationbased approach for device sizing is developed and for this a good optimization method is needed which can find good solutions and meet the specification parameters.

Nipahvirus : patologi hos en nyupptäckt zoonos

Nipahvirus is most likely spread from bats to other species and causes lethal encephalitis in humans and respiratory illness in pigs. Different species are affected with varying severity but it seems to have an unprecedented zoonotic capacity and the humans affected either die or receive permanent brain damage. Full recovery is possible but very uncommon. Pigs that live and are bread in the areas that these bats frequent are constantly in danger of contracting pneumonias and meningitis and they can spread the virus further on to the people who work with the pigs and process their carcasses. These workers could then infect other humans in their immediate surroundings, their families for instance.

Fältinstruktion för skogsbruksplanering av inhemska skogar i Andinska Patagonien :

The thesis first objective was to develop field instructions for forest planning of native forests in Andean Patagonia, and the second objective was to test the plan on an actual property in the area. The thesis was limited to studies in the province of Rio Negro. Today, there are no official forest management plans for native forests in the Argentinean province of Rio Negro; thus, there is an obvious need for an official forest management plan with clear guidelines. To be granted permission to manage, i.e. through thinning, the native forests on a property it is required to have a forest management plan that is approved by the Forestry Board in the province in question (Thill, B.

Utveckling av konkurrenskraftiga köpcentrum

Utveckling av ett köpcentrum är ett komplext system som involverar många aktörer såsom kommunen, fastighetsägaren, investerare, långivare, konsulter, analytiker, arkitekter, detaljister och givetvis även slutkonsumenten så att visionen om att vara den ledande bland köpcentrum hierarkin realiseras.Det tillkommer nya handelsytor i relation till befolkningsunderlaget i Stockholms län där konkurrensen, kundernas krav och e-handeln ständigt ökar. Detta kommer i sin tur sätta press på ledningen för att fastställa nya tydliga strategier för framtida visioner. Vid utvecklingen av ett köpcentrum har extern rådgivning tagits och därmed ett investeringsförslag har föreslagits. Vilka faktorer som har tagits med i beslutsunderlaget är det väsentligaste.Utgångpunkten med denna studie var att belysa hur ett köpcentrum behåller sin kommersiella kvalitet och därmed möta den framtida konkurrensen bättre. En Jämförelseanalys av två valda objekt i Stockholms län har fullgjorts för att belysa närmare framgångsrika nyckelfaktorer såsom läge, tillgänglighet och koncept.

Stereoskopisk 3D-film : En studie om tittarens upplevelse av 3D-film

Since the release of Avatar in 2009, the 3D movie industry has experienced an apparent growth. Almost all blockbuster movies are being released in 3D at the cinema, but the 3D format has been met with mixed opinions by the consumers. Some argue that 3D is the future, while others believe that the 2D format is enough for an appreciated movie experience. Through a qualitative survey, twenty participants with 3DTV in their homes answered questions regarding their experience of 3D movies and what improvements they desire. We suggest that 3D film creates immersion, realism and effects that 2D films can´t handle.

Latitudinal patterns in body size of Roesel?s bush cricketMetrioptera roeselii within and outside the continuous area of its distribution

Over time, species colonize new areas naturally or through humans. The colonizers areoften few and founded populations represent only a fraction of the genetic diversityexisting in the original population. If the established population becomes isolated afterthe colonization event genetic diversity will remain low and if the population, in addition,remains small in size for an extended period this will lead to increased inbreeding andpossibly inbreeding depression. Metrioptera roeselii is a common species with awidespread distribution in continental Europe. During the last century, it has expanded tothe Scandinavian Peninsula which is separated from continental Europe by the Baltic Sea.My aim was to test the hypothesis that individuals in isolated populations in Scandinaviaincluding Denmark and the Baltic Sea islands are smaller than individuals in thecontinuous part of its distribution due to low genetic diversity and lacking incoming geneflow.

Nyckelbiotoper - urskogsrester eller kulturprodukter? : beståndshistorik i tolv nyckelbiotoper i Lycksele kommun

Since 1993 the Swedish Forestry Administration conducts a nation-wide inventory of wood-land key habitats covering all forest land in Sweden. The inventory aims at mapping and describing habitats where redlisted species occur or can be expected to occur. According to the inventory stand history is crucial to the presence of red-listed species. However, the current knowledge of stand history in woodland key habitats is very limited. The purpose of this work is to describe stand history in woodland key habitats, i.e. fire history, human activities - mainly cuttings - and structural changes.

Arbetsplatsträffars effektivitet och utvecklingsnivåer : En observationsstudie inom en kommunal grundskola

The study aimed to highlight workplace meetings´ benefit and what level of development. The study was done at a school in Lidköping and included two qualitative observations. Most of the groups´ members were women; one man was included in each group, and there was a mixed age structure of the meeting participants. The collection of data was then paired with the scientific literature and scientific articles. .. Our results demonstrate that group 1 spend 59% of the time on information and 41% of communication.

Locally valued habitats, species and sites and their significance for collaborative land use planning around Manusela National Park, Central Seram Island, Moluccas, Indonesia

When new land use policies are made, opinions of stakeholders need to be taken in account, to avoid future conflicts. The motivations of commercial enterprises are often clear and easily communicated but due to inaccessibility and language barriers the indigenous people?s perspectives and needs are harder to reveal. This study therefore aims to identify species and sites of importance for the local people in Masihulan village on Seram Island, East Indonesia. This is a first step to facilitate better integration of local people´s needs into local government decision-making processes.Researchers at the Center of International Forestry Research (CIFOR), with headquarter in Indonesia, have developed an approached called ?Multidisciplinary Landscape Assessment? that aims to assess important natural resources for local communities in tropical countries.

Naturvårdande skötsel (NS) - blir resultatet som man tänkt sig? : en fältstudie över föryngring, trädslagsfördelning och död ved 14 år efter åtgärd

A new Swedish political approach to forestry was initiated 1993, that put goals of production and environmental issues into equal importance to Swedish Forestry Law. Earlier nature conservation very often declaimed preservation the best way to conserve nature, but recently it is clear that many highly biological values are due to former land use or disturbance. Many old pastures or cultivations dominated by deciduous trees are today characterized by a dense overgrowth of Norway spruce. By actively paying attention to nature in forestry (nature restoration), it is possible to partly reconstruct habitats or disturbances that are necessary to favour the biological values. The aim with this master thesis is to study the nature restoration, (NS, Swedish abbreviation), performed in 11 forest sites in the middle of Sweden 8-14 years ago. Since NS recently have become applied, it has never yet been evaluated.

Blandfoder i automatiska mjölkningssystem

A totally mixed ration (TMR) is a mixture of all the necessary feed components for the cow. She will eat the exact same feed in every bite which will make the rumen pH more stable and always supply her with a constant proportion between roughage and concentrate. This will make it possible for the cow to eat more dry matter (DM) a day because the fibre requirements are fulfilled. If a part of the concentrate is given separated from the mixture it is called partly mixed rations (PMR) and is almost always used when using an automatic milking system (AMS). When using TMR and PMR it is important to have a high hygiene, be accurate when mixing the feed and to look after cows in a good and strict way. The aim of this study was to document different farms with PMR in an AMS to see which routines they have and how they are managing their production.

Bokhögstubbar i Klåveröds strövområde : utbredning, egenskaper och betydelse för rödlistade vedlevande skalbaggar

Lack of dead wood is the main cause of decaying or loss of populations for many forest species. To increase the amount of dead wood is a prerequisite to maintain biodiversity in forests of northern Europe. In summer 2006 the recreation area Klåveröd, at Söderåsen in Skåne, Sweden, has been inventoried for high stumps (snags) of beech, (Fagus sylvatica). The result of the inventory has been compared with data of the real estate and forest management directories from the owner, region Skåne. The results have also been matched with the results from an inventory of saproxylic beetles in 2005, performed with windowtraps on selected snags both in the area and the adjacent national park Söderåsen. 594 snags were found on 747 ha.

Analys av individinriktad ekskogsskötsel i Blekinge : en metod för tillämpning i ett kontinuitetsskogsbruk?

Ett ökat brukande av skog enligt skötselprinciper som leder till skiktade beståndsstrukturer, en blandad trädslagssammansättning och kontinuerligt skogbeklädd mark har potential att öka den biologiska mångfalden och värdet för rekreation (Emborg m.fl. 2000, Berg m.fl. 1995, Mattsson & Li 1994, Holgen m.fl. 2000). I ljuset av detta, tillsammans med svårigheterna som finns att nå goda ekonomiska resultat vid skötsel av ädellövskog (Lindén & Ekö 2002), ses det idag som angeläget att uppmärksamma och studera alternativa skogsskötselmetoder (Cedergren 2008) . I östra Blekinge har ett antal skogsägare under längre tid praktiserat en metod att sköta naturligt föryngrad ek i blandbestånd som går ut på att, mer eller mindre tidigt, frihugga ekhuvudstammar, och att dana kvalitet genom stamkvistning/beskärning.

Identifiering av gallringsbehov med hjälp av flygburen laserskanning :

Thinning is one of the most important silvicultural activities in middle aged forests, partly to minimize damages and partly because it leads to earlier harvesting revenues and increases the value of the remaining trees. There are many different indices used to describe stand density and thereby the need of thinning in forests today. Studies have shown that forest variables can be estimated with high accuracy using airborne laser scanning and it is likely that the method could also be used to estimate forest density indices. In this study, the possibility of using the forest density index ?H² to determine and map priorities for thinning operations for a forest area was examined.
