There are two types of digital filters including Infinite Impulse Response (IIR) and Finite Impulse Response (FIR). IIR filters attract more attention as they can decrease the filter order significantly compared to FIR filters. Owing to multi-modal error surface, simple powerful optimization techniques should be utilized in designing IIR digital filters to avoid local minimum. Imperialist compe...

Plumbylenes are reactive intermediates whose discovery and characterizations are of great significance. Here, ten novel plumbylenes are introduced and characterised. A comparison is made between novel 1,4-di(R)tetrazol-5-plumbylenes (IR) with their corresponding 1,3-di(R) isomers (IIR), at DFT (R = H, Me, Et, i-Pro, and t-Bu). Every one of our plumbylenes (IR or IIR) appears less stable, with a...

Abstract—We present a subband adaptive infinite-impulse response (IIR) filtering method, which is based on a polyphase decomposition of IIR filter. Motivated by the fact that the polyphase structure has benefits in terms of convergence rate and stability, we introduce the polyphase decomposition to subband IIR filtering, i.e., in each subband high order IIR filter is decomposed into polyphase I...

A Solar Radio Burst (SRB) is one of the most severe natural hazards affecting performance global navigation satellite systems (GNSS). Considering influence different threat factors, GNSS developers upgrade to amend accuracy and noise-proof features systems. In particular, GPS gradually replaces “old” satellites (GPS IIA, IIR-A, IIR-B) with new-generation equipment IIR-M, IIF, III) featured by a...

Let IIR be the set of closed and bounded intervals of real numbers. Arithmetic in IIR can be defined via the power set IPIR (the set of all subsets) of real numbers. If in case of division zero is not contained in the divisor arithmetic in IIR is an algebraically closed subset of the arithmetic in IPIR. Arithmetic in IPIR allows division by an interval that contains zero also. This results in c...

A radiation-induced translocation, T(IIR----IIIL), has been shown to be nonreciprocal and to have most of IIR, including its terminus, attached uninverted to the terminus of IIIL.--Progeny with the IIR segment in duplicate, obtained from crosses of T(IIR----IIIL) to strains with a standard genome, were unstable at mitosis; like earlier duplication strains, they suffered deletions from either du...

PURPOSE To explore the possible existence of inward rectifying currents in the distal dendrites of amacrine cells. METHODS Patch-clamp recordings were made from amacrine cells in a new horizontal slice preparation of mouse retina. Single-cell RT-PCR studies were performed after the patch-clamp recordings. RESULTS In contrast to results from vertical slices or dissociated cells, all amacrine...

This paper proposes a new method of a pole controlled IIR adaptive digital filter (ADF) with a preceded FIR section, which consists of parallel connected second order IIR filters controlled by each inherent identification error. The FIR part works to identify a flat delay and responses resulting from poles near the origin of z-plane. On the other hand, the IIR part identifies poles near the uni...

This paper presents the swarm intelligence (SI)-based particle swarm optimisation (PSO) in context of designing infinite-impulse response (IIR) digital filters. IIR filters are the part of digital filters with recursive responses. Since the error surface of IIR digital filters is generally non-linear and multimodal, global optimisation techniques are required in order to avoid local minima. The...

Information Retrieval (IR) has benefited from standard evaluation practices and re-usable software components, that enable comparability between systems and experiments. However, Interactive IR (IIR) has had only very limited benefit from these developments, in part because experiments are still built using bespoke components and interfaces. In this paper we propose a flexible workbench for con...
