During the 1980s, the profile of recreational water quality at Sydney’s beaches caused concern among Sydneysiders. Monitoring of recreational water quality indicated that most Sydney beaches had poor water quality, and this condition was attributed to the disposal of partiallytreated sewage at cliff-face discharges. An epidemiological study conducted in 1989–1990 attempted to determine the prev...
In this paper, we propose a fast motion estimation algorithm to be used for motion-compensated frame rate up conversion (FRUC). The FRUC techniques are used to enhance the visual quality of the low frame rate video on display. By using the motion vectors obtained from motion estimation process, the new frames can be interpolated. The motion estimation is the key part of the FRUC process but it ...
The S-transform has widely been used in the analysis of non-stationary time series. A simple method to obtain depth estimates of gravity field sources is introduced in this study. We have developed a new method based on the spectral characteristics of downward continuation to estimate depth of structures. This calculation procedure is based on replacement of the Fourier transform with the S-Tra...
background: in vivo dosimetry is a method for estimation of overall error in the delivered dose to the patients at the end of radiotherapy process. in this research, two methods for target dose calculation were evaluated on midline and central axis of photon beams in in vivo dosimetry of thorax fields. materials and methods: entrance and exit doses for anterior and lateral fields of thorax were...
The Kuh-e-Sarhangi shear zone, with N70°E striking, is the northeastern part of the Kashmar-Kerman tectonic zone locating at the NW of the Lut Block. The Late Precambrian-Early Cambrian four granitic bodies have been intruded in the Kuh-e-Sarhangi shear zone. The Deh Zaman granite consists of two mezocrat and hololeucocratic bodies that are presenting strong ductile deformation and the mylonit...
This study proposes a method to estimate RBE of fast neutrons using Monte Carlo simulations. This approach is based on the combination of an atomic resolution DNA geometrical model and Monte Carlo simulations for tracking particles. Atomic positions were extracted from the Protein Data Bank. The GEANT4 code was used for tracking the secondary particles generated by fast neutrons during their in...

The new fast full search motion estimation algorithm for optimal motion estimation is proposed in this paper. The Fast Computing Method (FCM) which calculates the tighter boundaries faster by exploiting the computational redundancy and the Best Initial Matching Error Predictive Method (BIMEPM) which predicts the best initial matching error that enables the early rejection of highly impossible c...
