An Analysis of Traveling - Wave Mixer Structures (Signal Processing)
… are implemented utilizing acoustic charge transport technology, an approach which permits broad band delay lines, nonlinear elements, and active electronic components to be monolithically realized on GaAs substrates. The models are compared to the measured results, and excellent agreement …

The arctic submarine, an alternative to ice breaker tankers and pipelines
… many of the sites by the early 1990s. However, transport systems to bring this new found wealth to world markets are as yet far from fully developed, and are a problem. While there are two and possibly three potential transport technologies, all are e4pensive, high risk "megaprojects" which are …

Investigation of a Packet-Switched Inter-System Interface for Land Mobile Radio Systems
… exchanged between LMR users using the Real-Time Transport Protocol (RTP). Based on the proposed framework, we develop a simulation model to investigate the performance of the ISI when different numbers of LMR users try to establish unit-to-unit calls across the packet-switched ISI. Three packet …

Passenger assessments of quality in local public transport- measurement, variability and planning implications
… more detailed basis for planning of local public transport. With more knowledge of how segments of travellers assess different parts of a journey, bus routes can be planned to fit either all passengers or selected groups better. It will also be possible to evaluate perceived travel utility …

Predictive models for accidents on urban links - A focus on vulnerable road users
Much of earlier work on predictive models for accidents has been focused on rural traffic or urban intersections. This work has aimed at identifying and investigating possible improvements to predictive models for accidents on urban links. A special focus has been on the accidents of vulnerable …

On the Characteristics of Fires in Tunnels
Important phenomena related to tunnel fires are presented including both experimental and theoretical work. The main focus is on the large-scale fire tests performed in 2003, in the Runehamar tunnel in Norway. During these tests heat release rate (HRR), temperatures, gas concentrations (O2, CO2, …
