Ray-optical prediction of radio-wave propagation characteristics in tunnel environments-Part 1 : theory
A tunnel is modeled as congregates of walls, with the wall being approximated by uniform impedance surface. The aim is to get a solution for a canonical problem ...
Computer-aided design of a mass production circuit
Tolerance of the circuit components can sometimes bring about costly consequences in mass production. To tackle this problem, recent efforts have been dedicated to develop tolerant circuit design in order to boost manufacturing ...
On the Munn-Silbey approach to nonlocal exciton-phonon coupling
A canonical transformation method originally proposed by Munn and Silbey is used to partially diagonalize a model Hamiltonian which incorporates both local and nonlocal exciton-phonon coupling. At the heart of the method ...
Optimum quantizer design for pre-echo control in a low bit rate audio coding system
In a low bit-rate audio transform coding system, the quantization noise is spread out over the entire analysis block in the time domain after the inverse transformation in the decoder. This increases the likelihood of ...
Using power diode models for circuit simulations : a comprehensive review
In recent years, a number of new models for the power diode have been proposed. The objectives of this paper are to provide the power electronics community with a comprehensive review ...
Recognition of piano notes
In this paper, an algorithm for the recognition of musical sound from piano is proposed. The music signal is first digitally sampled and transformed from the time domain to the frequency domain using Constant Q ...
An overview of red-light surveillance cameras in Singapore
Unmanned, red-light surveillance camera systems help to reduce accident counts at intersections.
Musical sound recognition
In this paper, two different methods to implement one particular aspect of music transcription – musical note recognition – are presented. Both methods make use of existing algorithms in the form of the Constant-Q ...
Hybrid method of tolerance design
A new method of tolerance design, which we call the Hybrid method that accelerates the attainment of optimal design center, is proposed. The method combines geometry search with statistical process. At the start of the ...
A micropower-compatible time-multiplexed SC speech spectrum analyzer design
A micropower-compatible time-multiplexed sc speech spectrum analyzer embodying several new design methodologies is described. In the bandpass filter (BPF) section, the dc offset differences between channels are reduced by ...
