Based on the charge independence hypothesis the properties of V particles are theoretically investigated. It is found that the curious behaviours of these unstable particles are most simply interpreted in terms of the 1}-charge conservation law which directly results from the C. I. hypothesis and suitable isotopic spin assignments to these particles. The topics which are discussed in this paper...

There is a large gap between Zhang’s theoretical bound for the length n of a binary extremal self-dual doublyeven code and what we can construct. The largest n is 136. In order to find examples for larger n a non-trivial automorphism group might be helpful. In the list of known examples extended quadratic residue codes and quadratic double circulant codes have large automorphism groups. But in ...

Dynamic optimization of computer programs can dramatically improve their performance on a variety of applications. This paper presents an efficient infrastructure for dynamic recompilation that can support a wide range of dynamic optimizations including profile-driven optimizations. The infrastructure allows any section of code to be optimized and regenerated on-the-fly, even code for currently...

experience of double revolutionary upheavals in russia during the 20th century which produced a new socio-economic regularity on one hand and changed the political system from monarchial to democratic republic and then soviet state and finally presidential republic at the end of 20th century on the other hand are treated as democratic movements. in this regard, crumbling of ex-soviet regime and...

The notion of arc consistency plays a central role in constraint satisfaction. It is known since [19, 4, 5] that the notion of local consistency can be extended to constraint optimisation problems defined by soft constraint frameworks based on an idempotent cost combination operator. This excludes non idempotent operators such as + which define problems which are very important in practical app...

in this paper, we consider first-order fuzzy differential equations with initial value conditions. the convergence, consistency and stability of difference method for approximating the solution of fuzzy differential equations involving generalized h-differentiability, are studied. then the local truncation error is defined and sufficient conditions for convergence, consistency and stability of ...

introduction: falling is a common problem after stroke that occurs following the physical and psychological problems. psychological factors such as reduce of self-efficacy in maintain balance could have an equal or even greater contribution than physical problems in falling. therefore, having a suitable tool with acceptable repeatability seems to be necessary for evaluation of individual confid...
