PURPOSE Repeated brain MRI scans are performed in many clinical scenarios, such as follow up of patients with tumors and therapy response assessment. In this paper, the authors show an approach to utilize former scans of the patient for the acceleration of repeated MRI scans. METHODS The proposed approach utilizes the possible similarity of the repeated scans in longitudinal MRI studies. Sinc...

SUMMARY The polya posterior gives a noninformative Bayesian justification for various single-stage sampling procedures. Here this type of reasoning is extended to two-stage cluster sampling problems. The frequency properties of the resulting procedures are studied.

 In this research, a new control policy for the acceptance sampling problem is introduced. Decision is made based on the number of defectives items in an inspected batch. The objective of the model is to find a constant control level that minimizes the total costs, including the cost of rejecting the batch, the cost of inspection and the cost of defective items. The optimization is performed by...

Purpose: This study was conducted to provide an appropriate model to enhance teachers' motivation for the education process. Method: The research method was applied in terms of purpose and exploratory in terms of method. In the qualitative stage, the grounded theory and content analysis method was used and in the quantitative stage, the survey method was used. The qualitative part of the resea...

The creative universe is constantly expanding and so is its dimensionality with new forms of arts and entertainment, new technologies and new scientific specialties. Legal and economic conditions easily get turbulent in the drag of this expansion process, creating all sorts of idiosyncracies, puzzles and paradoxes surrounding legal rights and economic values associated with creators and their c...

objective: economic analysis was performed for the main horticultural crops in buin zahra (pistachio, peach, nectarine, and apple). there were dependent and independent variables in this research. methods: the independent variables were planting method (mechanized and conventional), land area used for fruit production, and land ownership. the maximum energy used, mostly in the form of fossil fu...

Binomial lattice models nd widespread uses in the valuation of derivative nancial instruments. When these instruments are path-dependent (non-Markovian), it is usually necessary to resort to Monte Carlo simulation. However, a crude Monte Carlo sampling of the lattice can be very ineecient since a large number of sample paths may need to be calculated. We develop procedures for sampling the path...

The multi-rate phenomenon of video unusual event is one of the factors to reduce the detection accuracy of video unusual event. Based on the infinite state Hidden Markov Model (iHMM), a multi-granularity detection algorithm for video unusual event is proposed. This algorithm first effectively extracts the feature sequence from the original data through subspace projection technique. Then the fe...
