En titt i backspegeln hjälper dig framåt - Hur tidigare erfarenheter kan användas för att vidareutveckla en Business Intelligence-lösning

Bakgrund och problem: Det talas om att misslyckade implementeringar ofta leder till att ITsystemavskaffas och ersätts. Detta trotts att det finns forskning som visar på fördelen med attinitiera en andra implementering för att effektivisera systemet och därmed öka nyttan avinvesteringen. Vi har analyserat medieföretaget Stampen, vars BI lösning anses som relativtframgångsrik. Stampen förbereder sin second wave-implementering för att förbättra ochexpandera sin BI-lösning. Vi skall därför undersöka vilka aspekter som är viktiga att ha iåtanke vid utvecklingsarbetet av en BI-lösning.Syfte: Uppsatsens syfte är att bidra till förståelsen för hur erfarenheter från en tidigareimplementering av en BI-lösning kan användas vid en vidare utveckling av de BI-lösningar,genom att göra en beskrivande fallstudie.

Nybyggnad till fårproduktion :

In Sweden we need more lambs during March to June. I decided to calculate on a spring lamb production, because to many of the Swedish lambs go to slaughter in the autumn. I counted on 1000 ewes which have 2000 lambs each year, 200 of these lambs stays on the farm and replace old ewes. The buildings are 3600 square meters. I have counted on two different sorts of buildings, the first one is a shed, the second one is three polytunnel sheephouses.

Årlig gödsling med NPK bäst för gröda, miljö och ekonomi

Yesterdays common fertilizing strategy was to apply phosphor (P) and potassium (K) in thefall a few times in the crop rotation. In the spring only nitrogen (N) was applied. Recent trialsand studies has shown that this strategy, N+P/PK, is ineffective compared with the systemwhere NPK is spread every year in the spring. The strategy with annual NPK-fertilizer in thespring has proven to be better for the crop, the environment and the farmers economy.In the NPK-system the crop responds with higher yields and better quality, especially in thespring cereals. This is mainly because of an interaction between the different nutrients in thefertilizer.

Naturvärdesbedömning av Utanåfladen; En inventering av vårlekande fisk, bottenfauna och vegetation

There are several thousands shallow bays along the Swedish east coast. Most of them are disturbed by different human activities, and undisturbed bays can be considered as quite unique. In the sheltered shallow bays water warms up more rapidly than adjacent water favoring the growth of vegetation, which in turns is beneficial to spring spawning fish species like perch and pike. It is nowadays more common that coastal habitats are inventoried to facilitate future preservation and planning. The aim of this study was to investigate the shallow bay Utanåfladen (59° 53`31.38 N 19°00`44.90 E) in the north Stockholm archipelago and evaluate its habitat value.

Igensättning av övre spalten i centrifugalpump

This report focuses on the upper slit. The upper slit is located between the impeller andthe drive unit. The slit design depends on pump type and application. However it isuncertain why the design varies, The purpose of this report is to clarify why the designvaries and to recommend an improved slit design.A research has been done; information was gathered from interviews, but also fromsearching of databases and studies of drawings, reports and documents. The originalpurpose of the slit was to prevent twining around the driveshaft, and prevent dirt fromentering the cooling system.

Förändringen av lipidskiktets tjocklek i tårfilmen mellan förmiddag och eftermiddag

Bakgrund: Symptom vid torra ögon kan vara en känsla av torrhet, irritation, okomfort, främmande kropps känsla och ökad produktion av tårar. Torrhetskänslan varierar under dagen men är mest påtaglig framåt kvällen. 3 av 4 som upplever symptom för torra ögon har ett tunnare lipidskikt. Diagnostisering av normala, måttligt torra och torra ögon kan dels göras med hjälp av en symtomenkät t.ex. TERTC-DEQ.Syfte: Att undersöka om lipidskiktet förändras i tjocklek från förmiddag jämfört med eftermiddag under samma dag.Metod: I studien deltog 6 män och 21 kvinnor med en medelålder på 23.3 ± 2.1 år.

Smart seed : fördröjd groning hos raps : försök med frö-coating samt litteraturgenomgång om frögroning, coating och praktisk tillämpning i reläodling

Oilseed rape constitutes a good break crop within a cereal dominated cropping system. The normal sowing time for winter rape in Sweden is August. It's a time in the cropping year characterized by a heavy work load, such as harvest and soil management. In addition, it is often a period with large precipitation. Thus, it is sometimes problematic for the farmer to do the sowing of winter rape at the optimal time.

Synchronizing migration with birth: an exploration of migratory tactics in female moose

Migration and giving birth are crucial decisions for animals during their life cycle, which may have lasting consequences on their population demography and fitness. Migration can entail a variety of possible effects for an individual, such as access to high quality food and reduced risk for predation. The moose (Alces alces) in northern Sweden is partially migratory and moose females are known to give birth to one or two calves. The synchrony between time of calving and timing of migration has not been compared before, especially in terms of energy maximizing and time minimizing perspectives, which may provide vital cues for fitness benefits of migration. I investigated effect of timing of birth and individual life history on distance, timing, stopovers and duration of 190 individually marked female moose that have been tracked for multiple years in ten different areas in northern Sweden.

Skogssådd med tall och gran : effekter av fröegenskaper och skärm/hygge på plantbildning, överlevnad och tillväxt de två första åren efter sådd

Over the past few years the Swedish forestry industry has become increasing interested in direct seeding. Although, in practice, this interest has been restricted to pine seed, the knowledge and techniques that have been developed for pine seeding can readily be transferred to spruce. Direct seeding is a method that is of interest to the forestry industry since it can lead to lower regeneration costs, denser stands and better root development than the more conventional planting method. This study evaluated experiments that focused on direct seeding of spruce in the northern Sweden. Skogforsk set-up the experiments in Gideå and Sävar in 2003.

Litteraturstudie: Evidens för stötvågsbehandling vid tendinos i rotatorcuff och lateral epicondylalgia.

Stötvågsbehandling är en behandlingsmetod som sedan början av 1990-talet blivit allt vanligare när det gäller behandling av tendinoser. Tendinoser är bla vanligt förekommande i rotatorcuffen och armbågen. Syftet med litteraturstudien var att undersöka vad det finns för evidens för stötvågsbehandling vid tendinos i rotatorcuffen och vid lateral epicondylalgia. Artikelsökningen utfördes i databaserna Pubmed, PEDro, CINAHL, Medline och COCHRANE. Sökningen genomfördes under januari och februari 2011.

CARABAS III Konstruktion av antenninstallation på helikopter

This report describes the construction work of a radar antenna for the radar systemCARABAS. CARABAS is a long wave airborne ground radar that has been developed bySAAB Microwave Systems and will now be mounted on a small helicopter, Schweizer 300.The antenna should be able to fold up and down. When the radar is in use the antenna islowered and under transport, start and landing the antenna is folded up. An emergency dropfunction should also be included in the design of CARABAS III.The extent of this report includes construction of the antenna, frame structure attached to thehelicopter, mechanism for folding the antenna up and down and mechanism for emergencydrop function. The mechanical design of the antenna and frame structure is based on modaland stress analysis, vibration measurement of Schweizer 300 and frequency analysis, andcalculations regarding aerodynamic drag and mechanics.The exciting frequencies of the helicopter and accelerations at those frequencies weredetermined by vibration measurement and frequency analysis.

Patologiska förändringar och säsongsmässiga variationer i testiklar från svenska brunbjörnar (Ursus arctos) :

Functioning reproductive organs are essential for the survival of a species. The reproductive system is very sensitive to exposure of chemical substances of anthropogenic origin. Humans release great amounts of chemical substances to the environment by our means of life and these substances have been proved to have a negative effect on the reproductive ability of different vertebral classes. In the polar bear (Ursus maritimus) a declined reproductive ability as an effect of decreased testosterone levels and decreased testicular size has been connected to the presence of high levels of organohalogenic compounds like PCBs. Although the Swedish brown bear (Ursus arctos) is not as carnivorous as its close relative the polar bear it is still exposed to environmental.

Säsongsvis avverkning : det operativa traktvalets påverkan på den säsongsmässiga uthålligheten i ett bolagsdistrikts traktbank

Due to soft grounds in combination with seasonal variation in soil humidity, there is a lack of stands that are possible to cut during spring and autumn in some geographical regions. For Holmen Skog this sometimes means that a large proportion of the contracted private forest is cut during the winter when the ground is frozen. One consequence of this is that the proportion of winter stands in the stand bank of own forest increases while spring and autumn stands becomes a scarcity. This in combination with milder winters, especially when there is a long period of reduced bearing capacity in spring or autumn, means that the situation rapidly can become critical. The overall goal with this study was to generate basic data for decision support in the work to achieve a sustainable distribution between own forest and contracted private forest in the stand bank. The study took place at Holmen Skog, district of Umeå, during autumn 2007 and was based on interviews and an analysis of harvest planning and delivery data. The study showed that there is a problem with how the cutting is distributed between own and contracted private forest during the year and that it foremost is the proportion of winter thinning of own forest that has increased in the stand bank.

Simulering av vågförhållanden i vattenkraftmagasin

Kraftindustrin arbetar oavbrutet med att försöka höja och upprätthålla dammsäkerheten i Sverige. Erosionsskydd för fyllningsdammar skall dimensioneras och utformas så att de medverkar till en god dammsäkerhet. Vid dimensionering och projektering av erosionskydd måste vågberäkningar utföras för att bedöma angripande våglast. I Sverige genomförs dessa beräkningar utifrån kraftföretagens riktlinjer för dammsäkerhet, RIDAS. Uträkningarna och bedömningar av våglasterna är ur dammsäkerhetssynpunkt viktiga eftersom de ofta avgör erforderligt fribord.

"...som ett trappräcke i en brant, brant trappa" : En religionspsykologisk studie av riter och kultur i copingprocesser hos drabbade av tsunamikatastrofen i Thailand 2004

Coping theory asks what the cognitive and behavioral patterns of individuals dealing with stress are. This essay includes, besides the perspective of the psychology of religion, theories of culture and ritual in exploring two Swedes coping with the natural disaster in Thailand year 2004. The vacation paradise was struck by an enormous flood wave, called a tsunami, causing vast destruction and the death of over 200.000 people. Among these 543 were Swedes on vacation. When a disaster of such measures happens, what kind of stress does it cause? How do you cope? Are religion and ritual important? What is the function of the culture in the copingprocess? Using hermeneutical analysis this essay interprets the material from two books by Swedes, who not only experienced the disaster, but lost two children and husband and wife in the flood wave.
