Abstract:
Traffic planners are facing a big challenge with an increasing demand for mobility and a need to drastically reduce the environmental impacts of the transportation system at the same time. The transportation system therefore needs to become more efficient, which requires a good understanding about the actual travel patterns. Data from travel surveys and traffic counts is expensive to collect and gives only limited insights on travel patterns. Cellular network data collected in the mobile operators infrastructure is a promising data source which can provide new ways of obtaining information rel

Abstract:
Missing from extant conflict literature is an examination of both symmetric and asymmetric conflict ties. To address this void, network analysis was utilized to examine the responses (both symmetric and asymmetric conflict ties) of 140 employees and managers in four divisions of a large agency of the Federal Government. The study was limited to conflict over scarce resources. Conflict management methods were examined as well as the perceptions of how respondents both cope with and feel about conflict. The results indicate that when two people in a conflict setting are structurally equivalent t

Among the low-power wireless technologies that have emerged in recent years, ultra-wideband (UWB) has successfully established itself as the reference for accurate ranging and localization, both outdoors and indoors. Due to its unprecedented performance, paired with relatively low energy consumption, UWB is going to play a central role in the next wave of location-based applications. As the trend of integration in smartphones continues, UWB is also expected to reach ordinary users, revolutionizing our lives the same way GPS and similar technologies have done.

Abstract:
Computer mediated communication (CMC) fundamentally influences the function of communication. It influences the organization's management and administration, but it most affects the dynamics of middle and lower level employees. The most simplistic model is that of an electronic office in which its employees need to know and understand the role of CMC. The purpose of this study is to investigate the performance and satisfaction of co-workers who use CMC to communicate within their organization, and to check employees' performance when using CMC.

The search for rules governing the successful management of organizations in different environments and following different strategies is well established. One central thread that runs through such contingency-type studies is that; as uncertainty increases, so does the necessity for more complex forms of communication and control. From such a premise it does not seem unreasonable to expect that systematic differences should be found in accounting across different organizations. The tools used for exploring such differences in this thesis are strongly influenced by one further line of reasoning
