Particle filtering is probably the most widely accepted methodology for general nonlinear applications. The performance of a particle filter critically depends on choice proposal distribution. In this paper, we propose using wrapped normal distribution as angular data, i.e. data within finite range (-π,π]. We then use same method to derive density filter, in place standard ...

This paper concerns the filter design problem for a recent proposed polyphase filter bank with arbitrary number of subband channels. According to the perfect reconstruction condition for I-D case presented in [ I ] , an analytical formula for the filter design is developed. Compared with direct numerical design algorithms. this analytical formula allows one to design the required low-pass FIR p...

The trans-admittance-mode (TAM) might act as a transforming bridge for voltage-mode to current-mode conversion. In this study a new low voltage operated electronically tunable TAM biquad filter structure realizing all the seven standard filtering functions namely; low-pass (LP), band-pass (BP), high-pass (HP), regular-notch (RN), low-pass-notch (LPN), high-pass-notch (HPN) and all-pass (AP) fro...

BACKGROUND In carnitine palmitoyltransferase I (CPT-I) deficiency (MIM 255120), free carnitine can be increased with no pathologic acylcarnitine species detectable. As inclusion of CPT-I deficiency in high-risk and newborn screening could prevent potentially life-threatening complications, we tested whether CPT-I deficiency might be diagnosed by electrospray ionization-tandem mass spectrometry ...

So far, we’ve been considering filters as systems that we design and then apply to signals to achieve a desired affect. However, filtering is something that occurs everywhere, without the intervention of a human filter designer. At sunset, the light of the sun is filtered by the atmosphere, often yielding a spectacular array of colors. A concert hall filters the sound of an orchestra before it ...

In hands-free telephones and teleconferencing systems, acoustic echo cancellers are required, which are often implemented by adaptive filters. In these applications, the speech input signal of the adaptive filter is highly correlated and the impulse response of the echo path is very long. These characteristics will slow down the convergence rate of the adaptive filter if the well-known normaliz...

In this review paper we showcase recent activities on silicon photonics science and technology research in Hong Kong regarding two important topical areas — microresonator devices and optical nonlinearities. Our work on silicon microresonator filters, switches and modulators have shown promise for the nascent development of on-chip optoelectronic signal processing systems, while our studies on ...

Retention efficiencies, pumping and respiration rates of the two Antarctic sponge species Mycale acerata and Isodictya kerguelensis from Potter Cove, King George Island, were measured. None of the species reached a 100% retention efficiency at any given particle size. This is probably due to the sediment-laden environment in which the animals were dwelling. A less efficient retention decreases ...
