In the case of navigation technology, designers have not always heeded either the environment or shipboard crew who are required to use the technology, often without benefit of training. Consequently, introduction of sophisticated technology has not reduced marine casualties, and has in fact resulted in accidents. The paper draws attention to factors that should be considered in the design and implementation of navigation technology, from the perspective of the end-user.","PeriodicalId":359446,"journal":{"name":"CCECE '97.

Grenier (1996) for direction-of-arrival estimation of highly correlated wave fronts with an uniform linear antenna array. The DEESE algorithm resides in applying a preprocessing to the estimated spatial correlation matrix before using the MUSIC method, which implies an eigenvalue decomposition of the correlation matrix. We will show that such a preprocessing can be applied directly to the sample vectors. This allows to significantly reduce the dimension of the eigenvalue problem and hence, to significantly reduce the execution time of the algorithm. Despite its reduced complexity, our algorithm gives better performances than the common spatial smoothing method.","PeriodicalId":359446,"journal":{"name":"CCECE '97.

The increasing complexity of the hardware requirements for smart sensor applications has led to the inclusion of field programmable gate arrays, FPGA, in the design of these systems. Two main advantages can be capitalized on with this approach, based on the characteristics of the FPGAs. Firstly, the design can be easily modified, reducing the design cycle time considerably. Also, as FPGAs are inherently parallel devices, both local processing and system partitioning are provided. The total system design in this project includes an application specific integrated circuit, ASIC, the FPGA, and a microcomputer. In this fashion the requirements for a smart sensor are realised.","PeriodicalId":359446,"journal":{"name":"CCECE '97. Canadian Conference on Electrical and Computer Engineering.

It prevents traffic overflow and resource under-utilization and is capable of achieving high network utilization while keeping minimum cell loss probability. This protocol uses explicit rate declaration on a link-by-link basis and derives the cell rate directly from the utilization of link bandwidth and the occupancy of buffer space at each switch. Design rules as well as control theoretical analyses are elaborated for understanding and evaluation of the protocol.","PeriodicalId":359446,"journal":{"name":"CCECE '97.

An overview of the design, installation, and operation the INS onboard USCGC JUNIPER is provided. The benefits of an INS from the perspective of the Officer-of-the-Watch are discussed. In particular, ECDIS and the DPS offer significantly improved mission capabilities for coastal navigation in shoal waters, for transits during periods of reduced visibility, for servicing aids-to-navigation (buoys), oil spill recovery, and for search and rescue/recovery.","PeriodicalId":359446,"journal":{"name":"CCECE '97.

Two types of rate-based schemes are supported by the ATM Forum specification, namely binary feedback and explicit rate feedback. Since the implementation of one of these schemes in ATM switches is left to the switch manufacturers, it is expected to have both types working on the same network. The compatibility of switches each running a different scheme was considered in the ATM Forum specification. However, since each type of switch has its own merits and demerits, the interoperability of these switch types and its impact on the performance of the network deserves extensive studies. This paper looks at the steady state performance of ABR service in networks consisting of both switch types (i.e. heterogeneous networks). In order to find the best locations for each switch type, several cases of switch type locations are considered. Moreover, the impact of ABR sources parameter setting on the performance of heterogeneous networks is studied.","PeriodicalId":359446,"journal":{"name":"CCECE '97.
