Synthetic X-ray images are simulated projected from CT data. High-quality synthetic can facilitate various applications such as surgical image guidance systems and VR training simulations. However, it is difficult to produce high-quality arbitrary view in real-time due different slice thickness, high computational cost, the complexity of algorithms. Our goal generate high-resolution by upsampli...

Constraint satisfaction problems are combinatorial optimization problems which involve finding an assignment to a set of variables that is consistent with a set of constraints. In this paper the use of two local search techniques, namely GENET and Tabu Search for constraint satisfaction optimization problems and partial constraint satisfaction problems is investigated. These methods are compare...

‎in this paper, using the idea of convexificators, we study boundedness and nonemptiness of lagrange multipliers satisfying the first order necessary conditions. we consider a class of nons- mooth fractional programming problems with equality, inequality constraints and an arbitrary set constraint. within this context, define generalized mangasarian-fromovitz constraint qualification and show t...

A constraint on the calculation of the ground transient resistance of overhead lines for small values of time is pointed out. The method for overcoming this constraint is proposed. The source of the ground transient resistance singularity is the low-frequency approximation of the ground impedance. It is shown that the ground transient resistance is not singular for t! 0 if it is calculated with...

Single carrier frequency domain multiple access (SC-FDMA) has been adopted for the 3GPP long-term evolution (LTE) uplink multiple access scheme due to the power consumption issue of mobile handsets. Like OFDMA in the downlink, SC-FDMA enables multiple users to be served simultaneously in the uplink. However, all subcarriers allocated to a single user must be contiguous in the frequency domain a...

The role of lexical frequency in syntactic ambiguity resolution was explored in two selfpaced reading studies of ambiguous reduced relative clauses. Recent constraint-based models of syntactic ambiguity resolution have proposed that for a reduced relative clause (e.g., ‘‘The room searched by the police was . . .’’), both the participle and past tense forms of the ambiguous verb (‘‘searched’’) a...
