(O)vanan att ta bilen : Motiv bakom bilanvändning till och från arbetet

von Seth, Julia, Bengtsson, Rebecca January 2013 (has links)
Tidigare forskning visar att kvinnor oftare reser kollektivt och att män kör mer bil till och från arbetet. Det framgår att vanor och miljömedvetenhet förklarar en del av människors resmönster. Studier visar också att kvinnor värderar bilens symbolvärde lägre än män. I samarbete med Eskilstuna kommun genomfördes en enkätundersökning med 2299 anställda vid Eskilstuna kommun, varav 491 män. Syftet med studien var att närmare undersöka motiv bakom bilanvändning och om dessa motiv skiljer sig åt mellan män och kvinnor i Eskilstuna kommun. Deltagarna besvarade frågor som berörde personliga resurser, vanor, bilens symbolvärde och inställning till miljön. Studien visar att de som använder bil till och från arbetet, har en större tendens att använda bil även i andra sammanhang. Det visade sig även att kvinnor reser med bil i större utsträckning till och från arbetet än män, vilket vidare bör undersökas då resultatet går emot tidigare forskning.

Optimizing manoeuvres for long collision avoidance active system of a car

Gonzalez-Carrascosa Partida, Ricardo January 2013 (has links)
This project presents the development of a collision avoidance active system for cars.There is a large interest in developing avoidance system in the automotive industry since the accidents are of such nature that can be avoided if the system works as desirable e.g., in animal crossing or having the car in front stopping without the driver noticing. A control system is designed to avoid collisions by acting on the steer and brakes of a car. An algorithm is developed to optimize a fuzzy logic controller which actuates on the steer and brakes of the car. The algorithm optimizes the inputs of the car, i.e. steer and brake, to avoid the collision with the object. The optimization of the trajectory implies that the car returns to the original lane and it is the minimum time possible inthe other lane. The object is situated at different distances and the initial speed of the car also varies depending on the situations. The results are obtained by using a car model that is developed in this project in conjunction with the tyre model, [1]. Simulations show that it performs collision avoidance manoeuvres in different conditions. Furthermore, improvements of the present work are suggested that are believed to further enhance the presented algorithm.

Understanding fracture mechanisms of the upper extremities in car accidents

Thieme, Sandra, Wingren, Magdalena January 2009 (has links)
The aim of this study was to understand injury mechanisms behind fractures of the upper extremities in car accidents. Volvo Car Corporation initiated this project based on the fact that no safety system today focuses on preventing injuries to the upper extremity. A literature study was undertaken focusing on the basic anatomy of the upper extremity, different fracture types and fracture mechanisms. Three subsets, from 1998 – January 2009, were selected from Volvo’s statistical accident database: 1) all occupants involved in an accident 2) all occupants with a MAIS2+ injury 3) all occupants with an upper extremity fracture. These subsets were used in a comparison, using frequency analyses. The comparison analysis showed that frontal impact is the dominating accident type for all three subsets. The comparison analysis also indicated that the risk for upper extremity fractures follows the pattern of MAIS2+ injury risk. An in-depth study using 92 selected cases, including 80 occupants, was also performed. All available information, such as medical records, questionnaires completed by the occupants and photographs from the accident scene was collected and analysed. The analysis of the in-depth study, together with knowledge retrieved from the literature study, resulted in six different mechanism groups that were used to categorise fractures. The groups were then analysed individually in regard to accident type and fractured segment of the upper extremity. Analysis of the mechanism groups showed that frontal impact is the dominating accident type in these subsets as well. It could also be seen that the fractures occurring in the in-depth study are quite evenly distributed along the upper extremities. Upper extremity injuries are relatively infrequent in car accidents but may result in long-term disability, including chronic deformity, pain, weakness and loss of motion. More attention is therefore necessary in order to develop a safer environment for car occupants.

Human Resource Professionals¡¦ Competencies in Car Manufacturing Industry

Chieh, Meng-Yueh 28 August 2003 (has links)
The major of this study is to examine human resource professionals¡¦ competencies in car manufacturing industry and identify their affectability.This study perceived 20 competencies in four domains: strategic human resource expertise, general human resource functional expertise, self-development and support & service for employee to examine their importance through the Analytical Hierarchy Process, AHP.The results of this study indicate that the HRM expert of car manufacturing industry weighting the strategic human resource expertise with 51.1% related to the other three domains, general human resource functional expertise with 21.8%, self-development 10.5% and weighting support & service for employee for 16.7%.The result emphasizes the importance of strategic human resource expertise and the general human resource functional expertise follows. The HRM competencies in Taiwan are still ranged in training and development of employee, usage of HRM information system, performance review and compensations & benefits. But the experts reach the common consensus that the strategic human resource expertise will be the most important competency for the requirement as the circumstance changing.

BMW iMPULSE : A wireless power future for the spontaneous Tandem Tribe

Hellby, Ernst January 2015 (has links)
Starting this thesis with the intention to inspire and to be inspired, I have tried to zoom out and look on designing a car from a new perspective. By telling a holistic design story rather than solving a specific problem I want people to imagine a future where one can live a modern and connected life in rural communities, all made possible after a green energy revolution. Design research, brand analysis, sketching, form verification using clay and digital modeling and advanced visualization were the main activities performed during the project. They helped me to explore, understand and successfully propose a complete story of vehicle and context. The result is BMW iMPULSE, a shared and fully autonomous vehicle that is wirelessly powered by clean energy and is always ready to support the spontaneous lifestyle

VOLVO MOBILITY & IMMOBILITY : CONCEPT DESIGN FOR SHANGHAI CITY 2050

Zhang, Yuhan January 2015 (has links)
The city landscape of China is undoubtedly experiencing rapid transformation. With the fast rate of urbanization it seems plausible that people will live in a vertical city served by new kinds of transportation infrastructure around the year 2050. This project studied the values of the upper middle class of migrants living in a future Shanghai. Ideation and form development resulted in an aesthetic sculpture informed by the western brand and the eastern culture. This sculpture then inspired the development of a vehicle concept that can act as mobility solution as well as an icon of quality living in the future Chinese home.

A Look at How Timing Affects Price of Used Car Auctions on eBay Motors

wood, warren 01 January 2015 (has links)
This study looked at 7194 completed listing from eBay Motors. Each observation contained a make, model, year, mileage, seller feedback rating, selling price, time of day ended, day of the week auction ended, auction duration, number of bidders, and number of bids for a car that had been sold on eBay Motors between March 16th and April 5th. Using this information this study looked at how timing affected the selling price of each vehicle, while holding the other variables constant. The observations are split up into four different time periods of the day (times are in Pacific Standard Time): morning (3am-8:59pm), midday (9am-2:59pm), evening (3pm-8:59pm), and night (9pm-2:59am). The regression results show that the midday time period increases the selling price of the vehicle by an average of $1445.41 for this data set. This is likely because the demand and supply side of the eBay Motors market are most equivalent during this time period compared to the other time periods.

Google Bespoke!

Shinomiya, Mitsuyoshi January 2014 (has links)
In my master thesis, I decided to focus on process of design. Nowadays, there is huge difference between the process of software design and hardware design due to technological problem. Software design development has more flexibility than hardware design development. In addition, it can be adjustable for each user and can involve user in design process. In the future, some of technology such as 3D printer, modifiable material, and so on, will enable hardware designer to use software design process to design hardware. The process can make better relation between user and product. In this thesis, I used real user to simulate the future process. I did a lot of interview to the user and involve him to design process. I used current technology to interact with user as much as possible, for example, I used 3D scanner to scan his body data to make perfect size reference for his vehicle. In the end, I could design something unexpected in good way thanks to collaboration with the user. It was also unexpected for him, but he was satisfied with the result so much. I believe this process has a lot of potential to make better relation and story between user and product.

Svenska Börsintroduktioner : En studie av avkastningen på Private Equity-noterade bolag

Börjesson, Wilhelm, Bäckström, Max January 2014 (has links)
I den här uppsatsen analyseras avkastningen på börsintroduktioner genomförda av Private Equity-firmor på den svenska marknaden under perioden 1993-2011. Studien undersöker huruvida börsintroduktioner genomförda av Private Equity genererar en abnormal avkastning relativt börsintroduktioner som genomförts av icke Private Equity, sammanlagt 97 börsintroduktioner. Båda urvalsgrupperna relateras gentemot jämförelseindex i form av kontrollfirmor på kort och lång sikt. Huruvida de två grupperna skiljer sig åt analyseras genom att beräkna respektive urvalsgrupps abnormala avkastning genom avkastningsmåtten Buy and Hold Abnormal Return (BHAR) och Cumulative Abnormal Return (CAR). Resultatet av dessa beräkningar analyseras sedan med hjälp av univariat analys och multipel regressionsanalys. I studien återfinns ingen skillnad mellan börsintroduktioner genomförda av Private Equity och börsintroduktioner genomförda av icke Private Equity på kort sikt. På lång sikt uppvisar börsintroduktioner genomförda av Private Equity högre avkastning än börsintroduktioner genomförda av icke Private Equity vilket är i linje med tidigare forskning. Båda urvalsgrupperna visar dock på lägre avkastning än dess kontrollfirmor på lång sikt.
