Background. The modern concept of acute leukemia therapy involves stratification patients into prognostic risk groups and a differentiated approach to treatment based on factors. However, antitumor treatment, including cytostatics, targeted agents, immunotherapy, cellular technologies, is not always highly effective, especially in with poor prognosis. development new high-tech diagnostic method...
The possibility of employing α-Al2O3:C (TLD-500) for estimation of gamma dose in mixed n-γ radiation fields by two peak method has investigated. It was found that the main peak can be reliably deconvoluted to two component glow peaks. The ratio of peak 2 to peak 1 in pure gamma ray radiation field (137Cs) is 1.49 whereas irradiation by Am-Be neutrons results in a ratio of 1.12. The precision of...
This paper presents a novel method for performing the registration and gamma correction of images in a simultaneous manner. The image registration and relative gamma estimation problems are formulated such that both problems are solved at the same time by solving a single minimum squared distance problem. The proposed method utilizes the Fast Fourier Transform (FFT) to solve the combined regist...
This paper proposes a software reliability model (SRM) based on a mixed gamma distribution, so-called the mixed gamma SRM. In addition, we develop the parameter estimation method for the mixed gamma SRM. Concretely, the estimation method is based on the Bayesian estimation and the parameter estimation algorithm is described by MCMC (Markov chain Monte Carlo) method with grouped data.
