Optimisation of multiplier-less FIR filter design techniques [PDF]
This thesis is concerned with the design of multiplier-less (ML) finite impulse response (FIR) digital filters. The use of multiplier-less digital filters results in simplified filtering structures, better throughput rates and higher speed.

Improved laminar specificity and sensitivity by combining SE and GE BOLD signals
NeuroImage, 2022 The most widely used gradient-echo (GE) blood oxygenation level-dependent (BOLD) contrast has high sensitivity, but low specificity due to draining vein contributions, while spin-echo (SE) BOLD approach at ultra-high magnetic fields is highly specific to

Prominent interior GE-filters of GE-algebras
AIMS Mathematics, 2021 <abstract><p>The concept of a prominent interior GE-filter (of type 1 and type 2) is introduced, and their properties are investigated. The relationship between a prominent GE-filter and a prominent interior GE-filter and the relationship between an interior GE-filter and a prominent interior GE-filter are discussed.

Imploring interior GE-filters in GE-algebras
AIMS Mathematics, 2021 <abstract><p>The concept of an imploring interior GE-filter is introduced, and their properties are investigated. The relationship between an interior GE-filter and an imploring interior GE-filter are discussed. Example to show that any interior GE-filter is not an imploring interior GE-filter is provided.

Spectral photosensitivity of diffused Ge-p–i–n photodiods
Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2020 Laser rangefinders are widely used to measure distances for various civil and military purposes, as well as in rocket and space technology. The optical channel of such rangefinders uses high-speed p–i–n, or avalanche, photodiodes based on Si, Ge or ...
