Optimization of iterative image reconstruction in PET/CT imaging procedures: A Patient-centered approach [PDF]
Egyptian Journal of Nuclear MedicineAim. The goal of this study is to optimize image quality metrics including Signal-to-Noise Ratio (SNR), Contrast-to-Noise Ratio (CNR), and Lesion-to-Background Ratio (LBR) while maintaining consistent Standardized Uptake Value (SUV(g/ml)) measures using ...

Square root kalman filter with contaminated observations [PDF]
, 1992 The algorithm of square root Kalman filtering for the case of contaminated observations is described in the paper. This algorithm is suitable for the parallel computer implementation allowing to treat dynamic linear systems with large number of state ...

Discussiones Mathematicae - General Algebra and Applications, 2021 A new algebraic structure was introduced, called an eGE-algebra, which is a generalisation of a GE-algebra and investigated its properties. We explore the definition of filters and the quotient algebra associated with such filters.

A parallel Kalman filter via the square root Kalman filtering [PDF]
, 1993 A parallel algorithm for Kalman filtering with contaminated observations is developed. Theı parallel implementation is based on the square root version of the Kalman filter (see [3]).

Performance modeling of industrial gas turbines with inlet air filtration system
Case Studies in Thermal Engineering, 2015 The effect of inlet air filtration on the performance of two industrial gas turbines (GT) is presented. Two GTs were modeled similar to GE LM2500+ and Alstom GT13 E2-2012, using TURBOMATCH and chosen to operate at environmental conditions of Usan ...

TWDM-PON With Signal Remodulation and Rayleigh Noise Circumvention for NG-PON2
IEEE Photonics Journal, 2013 We propose and demonstrate a 40-Gb/s (4 × 10 Gb/s) downstream and 10-Gb/s (4 × 2.5 Gb/s) upstream time-wavelength-division-multiplexed passive optical network (TWDM-PON) using signal remodulation. Here, a downstream differential-phase-shift-

Atmospheric ice nucleators active ≥ −12 °C can be quantified on PM10 filters [PDF]
Atmospheric Measurement Techniques, 2012 Small number concentrations render it difficult to quantify ice nucleators (IN) in the atmosphere active at warm temperatures. A useful new method for IN measurement based around filter collections is proposed. It makes use of quartz filters used in 24 h

Integrated Factor Graph Algorithm for DOA-Based Geolocation and Tracking
IEEE Access, 2020 This paper proposes a new position tracking algorithm by integrating extended Kalman filter (EKF) and direction-of-arrival (DOA)-based geolocation into one factor graph (FG) framework.
