ions in parallel with processes: F |P = λx ((F x)|P ). Concretions in parallel with processes: C|P = (fst C, (snd C)|P ). The remaining cases are given symmetrically. Processes P , Q of type P will—up to bisimilarity—be sums of prefixed terms, and by Proposition 8.7, their parallel composition satisfies the obvious expansion law. Ambient creation can be defined recursively in the higher-order l...
متن کاملAn Empirical Transmitted EPID Dosimetry Method using a Back-Projection Algorithm
Background: The present study aimed to introduce a rapid transmission dosimetry through an electronic portal-imaging device (EPID) to achieve two-dimensional (2D) dose distribution for homogenous environments. Material and Methods: In this Phantom study, first, the EPID calibration curve and correction coefficients for field size were obtained from EPID and ionization chamber. Second, the...
متن کاملIsolated Persian/Arabic handwriting characters: Derivative projection profile features, implemented on GPUs
For many years, researchers have studied high accuracy methods for recognizing the handwriting and achieved many significant improvements. However, an issue that has rarely been studied is the speed of these methods. Considering the computer hardware limitations, it is necessary for these methods to run in high speed. One of the methods to increase the processing speed is to use the computer pa...
متن کاملRemoval of Methylene Blue from Water by Polyacrylonitrile Co Sodium Methallylsulfonate Copolymer (AN69) and Polysulfone (PSf) Synthetic Membranes
Polyacrylonitrile-co-sodium methallylsulfonate copolymer (AN69) and polysulfone (PSf) synthetic membranes were prepared and used for the removal of methylene blue (MB) from water. Atomic Force Microscopy (AFM), Ionic exchange capacity (IEC), and Swelling ratio (Sr) were employed to determine the membrane characteristics. pH, membrane composition and initial dye concentration were used for t...
متن کاملApproximate by thinning: Deriving fully polynomial-time approximation schemes
We check that, letting Q := ( ), S and satisfy condition 3. Note that S† = [〈nil , const 1〉, 〈S′ ◦ (id × fst), suc ◦ snd ◦ snd〉]. Base case: 〈nil , const 1〉 ⊆ d e+ ◦ 〈nil , const 1〉 ≡ ([ ], 1) d e+ ([ ], 1) ≡ { definition of d e+ } ([ ], 1) δ 0 ([ ], 1) ≡ { definition of δ } [ ] ≤v [ ] ∧ [ ] ≥w [ ] ≡ true. For the non-empty case, let S′ = scons ∪ snd , we need that for a :: Item, x1, y1, y2 :: ...
