Environmental Impacts of Dams

Title: Ecohydrologic impacts of dams: A global assessment This project aims to improve the understanding of how dams and reservoirs impact freshwater systems worldwide. The following questions were addressed specifically: 1) what are the spatial patterns and magnitudes of flow regulation and channel fragmentation by dams globally; 2) how are dam impacts distributed biogeographically, and which are the biogeographic regions and taxa most threatened by dam impacts; and 3) how can climate change and dams be expected to interact in basins, and what management actions would mitigate adverse interactions....

Direct Drive Generator for Renewable Power Conversion from Water Currents

In this thesis permanent magnet direct drive generator for power conversion from water currents is studied. Water currents as a power source involves a number of constrains as well as possibilities, especially when direct drive and permanent magnets are considered. The high power fluxes and low current velocities of a water current, in combination with its natural variations, will affect the way the generator is operated and, flowingly, the appearance of the generator. The work in this thesis can, thus, be categorized into two general topics, generator technology and optimization. Under the first topic, fundamental generator technology is used to increase the efficiency of a water current generator. Under the latter topic, water current generators are optimized to a specific environment. The conclusion drawn from this work is that it is possible to design very low speed direct drive generators with good electromagnetic properties and wide efficiency peak.

Exact parametric differential equations of plane section rotations for beams with small and large deformations

This thesis has two theoretical parts and one part for results. The first part is a strict one. In the first part exact parametric differential equations of plane section rotations for beams are derived. Those differential equations show that using parametric sine and cosine functions for deflections, parameters and functions of the curvature angle for beams under bending can be defined via experiments. The second part gives one suggestion for functions of curvature angle. In the third part some comparisons are presented between results with parametric function derived in the part two, current theory, called Linear Elastic Theory for Small Deformations, and models that are presented in Appendix B (My Ideas for Future Development).

Advanced Traffic Service

More and more travellers use navigation-aid software to find the way while driving. Most of todays systems use static maps with little or no information at all about currently yeilding roads conditions and disturbances in the network. It is desirable for such services in the future to include information about road works, accidents, surface conditions and other types of events that affects what route is currently the best.It is also desirable to notify users about changes in the prerequisites of the chosen route after they have started their trip. This thesis investigates methods to include dynamic traffic information in route calculations and notifying users when the characteristics change for their chosen route... Contents 1.

Personal Rapid Transit systems for reduction in car dependence Karlskrona case study

This research project is designed to enhance the planning process that can aid authorities moving towards sustainable and economically feasible local and regional mobility systems. The improvements that have been made to transit so far have not been successful in breaking the trend of increasing car traffic and decreasing transit trip making. This means that sustainable mobility is a complex system which also encompasses changing attitudes and behaviours, integrating spatial and energy planning into it, and looking upstream to affect the causes of the problem instead of downstream to just fix its consequences. Environmental impacts (noise, pollution, health problems), accidents and congestion are all by-products of transport activities... Contents 1.

The usability of traffic signs

Guessability, learnability, experienced user performance (EUP), re-usability, and system potential are the five components that would influence the usability of a product. Usability assessments of many different types of consumer products, word processor, public library’s web site, online learning programs, and election incident reporting system have been reported. Traffic signs are probably the best known graphical symbols that we encounter along the roads and highways everyday. However, studies on the usability of traffic signs had never been seen. Three experiments were conducted in this research on investigating the sign usability in a comprehension task. Sign design features (i.e. familiarity, concreteness, simplicity, meaningfulness, and semantic closeness) and some probable user factors were also selected for detailed investigation of their effects on the five components of usability. The first two experiments used Mainland China traffic signs, while the third experiment employed Hong Kong traffic signs. No subjects participated in more than one of the three experiments. Experiment 1 was done for examining the guessability of traffic signs with … [Read more...]
