Ford Evoke

Goraczkowski, Sebastian January 2016 (has links)
„ What if Adaptive Personalization excelled Hardware Customization? “ Adaptive Vehicle Personalization Human mobility is about to create a generation of " Movers"  - a new breed of mobility users with global transportation  needs and a connection to multiple urban areas  already from a young age. Expectations towards mobility go towards adaptable and personalized solutions and technological advancements should enable a strategy in which one vehicle could adapt to multiple qualities. The final result is an adaptable urban mobility solution designed for global membership use in the year 2025. The intention of the project has been to holistically investigate how Vir tual Reality can influence the design process and result of interior and exterior. The goal has been to inspire and to show a believable way of how in the future adaptive personalization could excel hardware customization in order to suit the different and changing needs of various mobility service users.

The stock risk and return analysis of failure firms

Chiang, Yi-Chang 17 June 2000 (has links)
This study examines the failure firm¡¦s stock risk character and return behavior prior announcements day. This study includes three parts. First, we examine the risk different between failure firms and control firms. Second, we analysis the returns character of failure firms, and third, we test whether the different judgment announcements will affect the failure firms¡¦ stock return. We examine the daily stock returns between 1997 and 1999, 26 failure firms and 50 control firms have been observed. The empirical results can be summarized as follows: 1. Systematic risk behaves quite differently for the failure and control groups as much as two years before failure. 2. Both the total variance and the firm-specific variance behave quite differently for the failure and control groups only two months before failure. 3. The market is effective before announcements and not effective after announcements. 4. The shareholders of failure firms lost between different judgment announcements are no different in a short time. 5. The magnitude of the price reaction to failure filings depend on the probability of bankruptcy and proxy for predisclosure information impounded in stock prices over the year prior to failure filing.

A study of a Scale-sized Model for Analysis of Vehicular Antennas

Hsu, Yu-ching 20 June 2008 (has links)
In this study, we establish a car model which better resembles a real car and compare with the simplified car model as a reference. When taking the circular polarization antenna into consideration, we need the refined car model in the simulation. Besides, TPMS antenna measurements are conducted and the results are compared with the simulation to verify the accuracy of our simulation. The result of the simulation shows that the signal cannot be received when TPMS antenna is mounted on the rear tires. Proper solution is suggested to alleviate this problem. Due to the limitation of the measurement environment, we consider using scale-sized car model for the measurement of the antenna radiation pattern. Also, we compare the radiation pattern in the scale-sized car model with that in the full-sized car model. For the measurement of the vehicular antenna, we find that using the scale-sized car model for the preliminary estimation of the antenna radiation pattern is feasible and practicable.

A new spatial model for predicting multivariate counts : anticipating pedestrian crashes across neighborhoods and firm births across counties

Wang, Yiyi, active 2013 30 September 2013 (has links)
Transportation research regularly relies on data exhibiting both space and time dimensions. Thanks to the rise of smartphones, Bluetooth, and other devices, geo-referenced data collection enables application of more behaviorally realistic -- but complex -- models that account for spatial autocorrelation, temporal correlation, and possible time-space interactions (e.g., time-lagged effects from a neighboring unit's response). One promising area is crash count prediction, where crash frequencies (and severities) at zones, intersections, and along roadways will generally exhibit some spatial relationships, due to missing variables, causal mechanisms, and other ties. This dissertation work proposes and estimates a spatial multivariate count model and provides two case studies to implement such model. One case study is in the context of pedestrian-vehicle crash counts across zones in Austin, Texas, while accounting for network features (e.g., lane-miles and intersection density), land use factors (such as land use entropy and residential accessibility to commercial activities), population and job densities, and school access. The other case study pertains to new firm births by industries across U.S. counties while controlling for population density, agglomeration economies (e.g., percentage of firms with more than 100 people), wealth, and median age. The new model specification captures region-wide heterogeneity (thanks to extra variation introduced by the lognormal component in the mean crash-rate specification), correlations across two (or more) count types (in the same zone), and spatial autocorrelation among unobserved components. This new approach and associated application allow analysts to distinguish covariates' effects on multivariate crash and other counts from spatial spillover effects and cross-response correlations. This work adds to the literature by providing guidance on what types of specifications best reflect spatial count data while facilitating estimation (using large data sets) and illuminating the level and nature of spatial autocorrelation, multivariate correlation, and region-wide (latent) heterogeneity that exists in crash data after controlling for a host of observable factors. / text

EBH - Easy Battery Handling

Bengtsson, Sebastian, Nilsson, Kristoffer January 2008 (has links)
The project Easy Battery Handling - EBH has been carried out in our auspicial and completed for Devantini Corporation, a development company in Halmstad with its main concern in environmental friendly innovations. EBH has solved one of many technical challenges in one of Devantini corporation’s larger projects. This main project involves the development of an electric powered formula racing car. The part of this car that involved EBH was the battery handling to guarantee safe and quick battery exchanges during pit-stops. The solution became an entire battery module, hanging on the side of the car on two spears pointing out from the car. The batteries are exchanged by a specially designed trolley that is inserted under the battery module. To secure the batteries whilst driving they are also secured with a locking device that is quick and simple to unlock when it is time to exchange the batteries. The project resulted in a battery handling system that in comparison to already existing solutions reduce the burden on the mechanics and performs an exchange of batteries in less than half the time.
