Examensprojekt: WERA Stockholm

This project is an attempt at creating a bag that is both functionaland has an interesting and relevant visual appearance. I have found that a bag that is functional usually have adapted certain aesthetics which are appealing only to a very limited target group. At the same time many bags that are more focused on style can be downright disabling to the carrier. I wanted to create a functional bag, and to explore new functions doing this, while working with aesthetics that stayed relevant and interesting to my target group. The bag was designed for the company Åhléns and their label WERA Stockholm, and theircustomers was the target group.

Frystorkning Kontrollerad torkning av kulturhistorisk dräkt?

Cultural objects may become wet by deliberate water cleaning, water disaster or watersoaked for other reasons. Air drying textile objects and even other organic materials from awater wet state, involves many problems depending on the strong capillarity action of water.Damages and changes such as bleeding of dyes, stains or lines of impurities from watermovement, shrinking or stiffness can occur. Freeze-drying as an alternative drying methodhas often been used for wet archaeological and marine objects, but more seldom for historicalmaterials.This bachelor thesis addresses the issue of whether freeze-drying can be an alternative controlleddrying method for historic costumes. Costumes and related objects are often compositeobjects, consisting of multiple materials, as well as being three dimensional, all of whichwill complicate drying. The purpose of this study was to investigate whether it is possible tohandle costume objects after wet cleaning for drying by freeze-drying, and if damages due tosurface tension of water, can be avoided in this way.

How to future proof a Business Model : Capture and capitalize value in the field of Urban Mining

Context: During the 21st century several alarming reports have been published that deals with the depletion and pollutant of the earth by human interference. The earth is an ending resource and so are the mountains and bedrocks which are continuously mined in order to harvest its minerals. The idea behind Urban Mining is to (re)invent processes enabling further purpose for materials both from old deposits and new products providing secondary raw materials and energy. This thesis aims to investigate the challenges and opportunities of how firms and organizations can and will be able to strike a better balance between product-/service systems, economic growth and environmental stewardship in the context of Urban Mining as an approach. With the innovation of processes, technology, business- planning and creation in focus.Objective: How to future proof a business model for Urban Mining by the usage of business model design.Method: This thesis will be conducted using a case study approach, meaning that it will incorporate qualitative, exploratory and descriptive characteristics - aiming towards enabling both applied and fundamental research.Results: The result evaluates the business model element differences between traditional C&D industry and Urban Mining industry.

Gymnasieelever och bråkräkning

For many years, I have tried to understand why students end up in difficulties in mathematics. As a future teacher, it is extremely important to have knowledge of the various factors that leads to difficulties in mathematics. As a teacher it is obvious to meet the students who find mathematics a difficult subject, and, therefore it is necessary to have a broader knowledge of how to respond and support these students. According to Ahlberg, number of students with mathematics difficulties is increasing every year, therefore, it is important to help students and organize a supporting school environment that promotes and encourages learning (Ahlberg 2001, p. 104-105).

Medveten måltid : Ett begrepp i förändring

The key elements of sourdough fermentation are the presence of active lactic acid bacteria (LAB) and yeast. Sourdough fermentation originates from the ancient Egypt. One theory concerning its onset states that a portion of bread dough was set aside to be baked at a later date and started to ferment spontaneously.Sourdough may contain a wide variety of microorganisms, mainly dominated by LAB and yeast. There are over 50 species of LAB that has been identified in various sourdoughs and more than 20 species of yeast. Sourdough fermentation has been shown to have various impacts on baked cereal good, most of which are attributed to LAB.This study addresses some effects of LAB from fermented milk products in sourdough and sourdough bread.

A Computer Laboratory on Active Sound Control

Syftet med detta examensarbete är att utveckla en datorlaboration baserat på aktiv ljudreglering för kursen reglerteknik allmän kurs för maskin och farkostteknik vid Kungliga Tekniska Högskolan KTH. Arbetet ska innefatta en utveckling av en matematisk modell av rörsystemet som ska regleras med en lead-lag regulator. Rörsystemet vid Marcus Wallenberg Laboratoriet ska användas som modellsystem, och den matematiska modellen ska baseras på mätningar insamlade på detta system.Den matematiska modellen skapades med hjälp av ett s.k. identifieringsexperiment och identifieringen baserades på en viktad minsta kvadratanpassning av insamlade frekvensdata. Modellen anpassades till en överföringsfunktion som visade sig ha ett nollställe i komplexa högra halvplanet, vilket motsvarar en svår bandbreddsbegränsning för den aktiva ljuddämpningen.

Laborativ matematik : Är det ett gynnsamt arbetssätt i matematikundervisningen?

Att eleverna i skolan ska utvecklas och nå de mål och kunskapskrav som finns skrivna i läroplanen är en central del i skolvärlden. Men hur når man då dessa på bästa sätt? Hur ska man som lärare veta vilken undervisning som är bäst för sina elever? I läroplanen står att eleverna ska ges en varierad undervisning där eleverna själva ska få gestalta, prova och utforska (Lgr11). Syftet med denna litteraturstudie är att undersöka om laborativa arbetsätt i matematik är gynnsamt för eleverna. I studien framställs att arbeta laborativt kan vara gynnsamt men till en viss del och att det beror på en del olika faktorer, som exempelvis lärarens roll och hur väl uppgiften och materialet framträder varandra..
