Dagvattendammars reningseffekt : påverkande faktorer och metodik för statistisk modellering
Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.
Företagsstudie om värmeöverföring : Beskrivning av värmeflöden hos en lagerbyggnad
The study took place at a food corporation in Växjö, Sweden. It describes a building that contains four tanks in which glucose syrup is stored. The purpose of the study was to calculate the amount of heat that leaves the building and the amount of heat that is supplied by the installed heating equipment. Before the calculations could be implemented, all the systems that supply the building with heat had to be examined. With a small amount of information from earlier studies, the work to gather all the data necessary for the calculations began.
Reducerad jordbearbetning : en fallstudie
This is a study made because I would like to see how much money can be saved when
reduced soil preparations is used. This is a case study, the farm is located in the north
vest part of Skåne, Sweden.
I have calculated with four different soilpreparation methods.
Alternative 1: Conventional soil preparation, the way the farm is managed today.
Alternative 2: Ploughing on depth of 12 centimeters, with a ridge packer followed with
sowing.
Alternative 3: Eco-tillage
Alternative 4: Direct drilling
The results of my study showes that Alternative 2 is the most profitable. Alternative 4 is
very good if you see to dieselexpenses and hours of work, but the yield is far to low.
If the numbers are further analized, it showes that in spring barley the differense
between Alternative 2 and Alternative 4 is at a minimum. So if there is lack of time for
one reason or another, this might be an alternative in spring barley.
The differense in how the farm is managed today and the most profitable alternative in
the study, Alternative 2 showes that it can be saved up to 60 940 SEK..
100 ?r av tradition - kaktusgrupper: en kunskapssammanst?llning av ett bortgl?mt kulturarv
This bachelor?s thesis is a study that examines cactus groups in Sweden from a heritage conservation
perspective. Through interviews and an analysis of both historical and modern literature, the research
explores why cactus groups became popular and what is required to preserve those still in existence
today. A recurring challenge has been the lack of comprehensive source material, leaving some
questions open for further research. The study focuses on four cities?Norrk?ping, Skellefte?,
Varberg, and V?xj??that have maintained their cactus groups for nearly a century.
Phosphorus in agricultural soils around the Baltic Sea : comparisons of different laboratory methods as indices for phosphorus leaching to waters
Eutrophication of the Baltic Sea is a serious problem. A major contributing factor is diffuse losses of phosphorus (P) from agricultural land in surrounding countries. In order to estimate P losses, environmental monitoring of small agriculture-dominated catchments is being carried out in most of these countries. Evaluation of the risk of P leaching to waters is usually based on chemical tests originally developed to quantify the amount of soil P available for plant production. The tests are performed in different ways in the different countries and a number of different extraction agents are in use.
Drama & vägledning : Metoder som speglar livet
This study illustrates how drama methods and career counselling might interact. The aim is to investigate whether drama methods can enhance career counselling methods. Drama is here defined as an umbrella term that includes all forms of action methods used in psychology and education.A literature survey was carried out in parallel with qualitative research interviews. Three professional drama leaders were interviewed separately. This was followed by a group interview with five upper secondary school students, who had all taken a course in drama with a focus on personal development.The findings show that there are common and consistent goals and values between drama and career counselling.
Aspect Analyzer: Ett verktyg för automatiserad exekveringstidsanalys av komponenter och aspekter
The increasing complexity in the development of a configurable real-time system has emerged new principles of software techniques, such as aspect-oriented software development and component-based software development. These techniques allow encapsulation of the system's crosscutting concerns and increase the modularity of the software. The properties of a component that influences the systems performance or semantics are specified separately in entities called aspects, while basic functionality of the property still remains in the component. When building a real-time system, different sets of configurations of aspects and components can be combined, resulting in different configurations of the system. The temporal behavior of the system changes and a way to ensure the predictability of the system is needed.
Relationer och projekt : En studie av det mellanmänskliga i det rationella
Projects are often spoken of in the terms of rational systems. However, some researchers point out the relevance of viewing projects as sets of relationships. Little is published about what aspects of relationships that are important for the managing of projects. We have argued for the necessity of such research. With previous research, our case study and interviews we indentified communication, responsibility, cooperation, togetherness and trust as important relational aspects in projects.The overall perceived success for projects in this case, was increased with the adoption of new agile methods.
Valet inför valet : En studie om hur svenska förstagångsväljare väljer att ta del av politisk information
Problem statement and purpose:The purpose of this study was to analyze in what way first-time voters chose to take part of political information. The questions we aimed to answer was how first-time voters use media and other information channels for political purposes, what importance and trust the first-time voters give the different information channels and finally which indicators there is for that structural or individual factors affect the media consumption and political interest.Method and material:We did interviews with twelve 18 years old first-time voters from six different high school programs in Sundsvall, Sweden.Results:The study showed that the premier source of political information were traditional news media, in particular the debates on TV. It?s also in the debates the first-time voter?s trust the most. Even though the social medias are constantly present in their everyday life and even though the first-time voters believe the social medias have potential for engaging young people politically, the possibilities are only taken in advantage by people who are already politically interested.
Just-In-Time-aspekter: Scania
Denna uppsats har för avsikt att utreda begreppet Just-In-Time (JIT) och dess komponenter för att sedan försöka finna dessa i den svenska lastbilstillverkaren Scanias produktionssystem. Litteratur har bidragit med en definition av JIT som sedan har jämförts med hur Scania arbetar inom produktionen. Empiri har erhållits genom intervjuer med berörd personal samt observationer på plats i Oskarshamn och i Södertälje.För japanerna är inte Just-In-Time-tänket en ny företeelse utan det är något de har arbetat efter en längre tid. Denna uppsats har valt att utgå från Jeffrey K. Likers (2004) definition i The Toyota Way.

The advantage and the possibility of keeping track of a number of vehicles to make work practice more effective and smooth is today a favorable choice for Visual Units Logistics customers. We?ve been evaluating the software and trying to take it one step further and letting not only the individual user, but maybe, the company as a whole benefit from its advantages. This has been done by using methods like letting ourselves get to know the software, user case studies, workplace studies, interviews and future workshops. This resulted in a prototype introducing a new function designed with all collected data in mind trying to make the software, Visual Units Logistics, even more effective for the every day work practice of the user.
Hur ser elevernas läs- och skrivvanor ut på fritiden?
My curiosity concerning what pupils read and write during leisure time led me to gather information using a quantative method. The study's aim is to investigate which reading and writing habits they have during their time outside school. A comparison was done of pupils at school year level 3 and level 4 in two different schools with the intention of investigating the influence of social background on reading and writing habits. 137 pupils filled in survey forms and thereafter the MYSTAT statistic program was used to process the information. The results point towards that the pupils read story books both more often and for a longer time than any other type of literature and that they read them often or very seldom.
Skydd mot yterosion i slänter av finmorän
Slopes in fine till soils are exposed to surface erosion due to rainfall, snowmelt and upland water sources. Large areas of road slopes are therefore covered for surface erosion protection. Preventive methods like ditches and trenches are also being used. Silt tills are particularly troublesome since the water can bring the soil into suspension and cause mudslides. Different methods for erosion protection have been studied in this work, with the emphasis placed on rockfill covering. The need for and the dimensioning of this type of covering has been examined in literature and field studies.
Dyskalkyli : En kvalitativ undersökning om hur fyra pedagoger i specialpedagogisk funktion arbetar kring dyskalkyli
Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.
Comparison of two methods for evolving recurrent artificial neural networks for
n this dissertation a comparison of two evolutionary methods for evolving ANNs for robot control is made. The methods compared are SANE with enforced sub-population and delta-coding, and marker-based encoding. In an attempt to speed up evolution, marker-based encoding is extended with delta-coding. The task selected for comparison is the hunter-prey task. This task requires the robot controller to posess some form of memory as the prey can move out of sensor range.
