This report is the result of a case study at Peltor AB during the spring semester of 2007. The task Peltor gave us was to improve the delivery accuracy and to lower the high finical value of delayed orders (backorder), and to divide the products into logical groups. The logical group will be a useful tool to remain a high level of service. If the level of service increases the company will be more competitive.The electronic department at Peltor has problems with delayed orders. According to Peltor, the problem is based on delivery lead time which is presumed.To increase the delivery accuracy, a lead time analysis is made to find the accumulated delivery lead times for each product.

!is began as a product design challenge, which stipulated broadlythat the designer be ?inspired by a subject?, whose ideas would leaddown a path of product idea evolution. From there, the goals forthe end-product would undergo rigorous revisions, re-de#nitionand re#nement. !e end-product itself would be the result of anentire thinking process.!e subject I have chosen is: Time. I want to challenge and evenalter our conventional sense of time, using principles ofdesign.

SARS [Severe Acute Respiratory Syndrome] penetrated China in spring of 2003, created havoc in the social society, exposed weaknesses within the political system and pushed the nation towards a crisis of confidence. At the same time the crisis revitalised the Party's position, brought people from different social stratum together and had a beneficial impact on the populace's knowledge on health related issues.What makes the SARS crisis in China interesting for further and deeper investigation is the method it chose to respond to its national crisis. They plan of response was indeed a retrogression back to "older" times, using methods and propaganda very much like those used during Mao Zedong and later Deng Xiaoping. The first step of response was denial and cover up of the real situation, which quickly turned to unprecedented transparency, as the magnitude of SARS became known. The Party and the government were quick to proclaim themselves as the bearer of the key knowledge and information on how to best fight the disease, this in sharp contrast to the political trend of more co-operation between the private and public sector and political transparency.

Background: The population of the world is getting older and in the year of 2020, 1.2 billion people will be 60 years or older. A common health complaint affecting the quality of life in elderly persons are sleep difficulties. Physical activity is claimed to improve sleep quality and the maintenance of a normal circadian rhythm. Several studies have shown positive effects of physical activity on sleep quality, still the evidence of physical activity as sleep-promoter is insufficient. Aim: The aim of this study was to investigate associations between physical activities and sleep quality in persons ?60 years of age.

This Master?s thesis is the first to quantitatively study the prevalence of library anxiety at a Swedish university. Library anxiety is a concept describing the negative feelings students can experience when using the library. The study was conducted using web questionnaires sent out to 512 students at Växjö university. 38 % responded and the results were analysed with the help of, amongst other methods, correlation studies.

The purpose of this study is to examine how pre-school teachers think about the importance of circle time in regard to the child's language and social development from a sociocultural perspective. Furthermore the study will include what role the educators? have during the circle time.To answer our purpose we have chosen the following question:What is the role of the teachers in the circle time?What are the teacher?s thoughts about the circle time?s importance to children's social development?What are the teacher?s thoughts about the circle time?s importance to children's language development?The study is constructed on qualitative methods, where we conducted structured interviews with six preschool teachers and observed their circle time to collect our empirical material. The study is also based on Vygotsky's sociocultural perspective which says that all learning takes place through relations and interaction with other people in the cultural context you are in. The results have shown that pre-school teachers are aware of the circle time?s importance to children?s development, and purposely plan the circle time to give children the opportunity to develop both socially and linguistically skills..

Proteins are vital to all cells in the body. They consist of long chains of amino acids. To be able to study the amino acid composition of a protein it is necessary to hydrolyse it, followed by separation and quantification. When the protein is hydrolysed, in this case ß-lactoglobulin, the protein is divided into individual amino acids. The method that traditionally has been used to hydrolyse proteins takes 24-72 hours to complete.

Few would disagree that the media landscape has undergone significant changes the last decade. From bulky computers and plain mobile phones to portable High-Definition computers and multi-functional smartphones. Other media, such as newspapers and music, have evolved and prospered in a digitalized environment. The constant urge to digitalize aspects and functions of our daily lives seems almost instinctive. Television has taken further steps into this environment as it is now accepted and featured via the Internet.

The lions at Kolmårdens zoo are vaccinated against Feline Panleukopenivirus (FPV). In 1994 there was an outbreak among the lions at the zoo of FPV disease. A retrospective study has been made to measure the antibodytiters in vaccinated lions and lions that lived during the outbreak. An ImmunoPeroxidase Monolayer Assay (IPMA) was used to analyze the titers in the sera from the lions. Lions were divided into five groups. Group 1, 2 and 3 contained lions vaccinated one, two and three times respectively (a total of 40 animals). The lions of Group 4 were born in 2004 (six lioncubs) and were vaccinated according to different regimes and the changes in antibodytiters were followed as respose to vaccination during the spring 2005.

Music production software has a strong tradition of two-dimensional graphical user interface (GUI), in which the time line is represented as a flat composition either horizontally (from left to right) or vertically (from top to bottom). In my degree work titled Sequi, I approach music composition from a different angle. Instead of a two-dimensional time line with only two possibly ways of progression (forward or backward) I constructed a three-dimensional GUI with the maximum of four different ways of progression from any given point in a composition. The height axis is used to describe time-intervals (the time between downbeats) and the wide and depth axes are used to describe progression from one sound to another..

In 2014, the Swedish leisure-time centres after school became widely criticized on several occasions by school authorities. The cause for its criticism was a reflection of leisure time-centres with lots of untrained staff and a lack of pedagogical aspirations. The conclusion of the criticism was that these leisure-time centres do not fulfil their potential. However, these assessments has only to a limited extent become a part of the public educational discourse in Sweden. This discourse has mainly focused on the decreasing results in the Swedish school, which has caught the attention in the media and ended up on the political agenda.

The aim of this study is to look at the environmental effect on toddlers? social interactions during free play in two older and two newer preschools. Furthermore, we would like to investigate four preschool teachers? thoughts about the indoor environment when it comes to toddlers? interaction during free play.Qualitative methods containing interviews of the preschool teachers and observations of the children during their free playtime have been used to help us reach our conclusions. In addition, our theoretical conclusions have been derived from both the sociocultural perspective and the environmental psychology perspective.Our results have shown that variations in the preschool environment are of importance in the outcome of toddlers? different social interactions.

Based on earlier experiences of mathematics and mathematical learning, both as a student and as a teacher, I became more and more interested in how well the publicly accepted opinions about mathematics as an uninteresting, difficult and ?geeky? subject corresponded to reality. What do Swedish pupils really think about mathematics and is it possible to identify any differences in their attitudes based on the pupils? age?From this point of view the following questions were formulated:·What are pupils? attitudes towards mathematics in grades 3, 6 and 9 and how do they conceive their learning conditions?·Is it possible to detect any differences in the attitudes and preferences depending on the pupils? age?The result of this study compares well with previous studies done in this and overlapping fields and indicates that:·Younger pupils tend to have a better liking of mathematics but with increasing age that interest fades out.·Most pupils, without regard to age, consider mathematics to be one of the most important subjects, despite the fact that many pupils also find mathematics difficult and boring.·For pupils of all ages, the teacher is the most important factor in the learning process. Older students have more specific demands on the teacher for knowledge and pedagogical skills.·A high noise level, talking and disturbances in the classroom are the most bothering elements when it comes to learning mathematics.

Sudoku solvers are a widely researched topic among mathematicians and computer scientists. This report investigates the differences in execution time and time complexity between backtracking and human strategies for classes with 17-21 clues. Backtracking is compared to our implementation of human strategies with test data that contains 99 Sudoku puzzles for each class. The study shows that the execution time and time complexity is improved for human strategies compared to backtracking for each class. The conclusion shows that it is always favorable to implement the human strategies investigated in the report. .
