This paper presents an improved version of incremental condition estimation, a technique for tracking the extremal singular values of a triangular matrix as it is being constructed one column at a time. We present a new motivation for this estimation technique using orthogonal projections. The paper focuses on an implementation of this estimation scheme in an accurate and consistent fashion. In...

Papadatos, C., Alexiou, D., Nicolopoulos, D., Mikropoulos, H., and Hadzigeorgiou, E. (1974). Archives of Disease in Childhood, 49, 927. Congenital hypoplasia of depressor anguli oris muscle: a genetically determined condition? The frequency of hypoplasia of the depressor anguli oris muscle was 37 cases among 4 530 consecutive births (8 -2 %). Diagnosis was based on clinical and electromyographi...

The condition-based approach for consensus solvability (that we have introduced in a previous paper, ACM STOC’01) consists in identifying sets of input vectors for which it is possible to design a protocol solving the consensus problem for n processes despite the occurrence of up to f process crashes. For each value of f these conditions actually define a hierarchy. This paper continues our inv...

We give a simple characterization for a nonassociative algebra A, having characteristic 6= 2, to be commutative. Namely, A is commutative if and only if it is exible with a commuting set of generators. A counterexample shows that characteristic 6= 2 is necessary. Both the characterization and the counterexample were discovered using the computer algebra system in [2].

contracts sometimes disband to different reasons. one of contracts disbanding causation is resolutory condition. on this base parties stipulate if incident, act or omission arise contract disband. at this face contract disband with acquirement condition on it. in such cases dissolution ground is willing and consequence appears automatically. in truth resolutory condition there is doubt that wit...

We investigate a set of adaptive±stencil, ®nite-volume schemes used to capture sharp fronts and shocks in a wide range of ®elds. Our objective is to determine the most promising methods available from this set for solving sharp-front advective±dispersive transport problems. Schemes are evaluated for a range of initial conditions, and for Peclet and Courant numbers. Based upon results from this ...

background: to increase safety of patients and staffs in hospitals, safety standards and regulations must be considered. this study was conducted to evaluate safety conditions in hospitals affiliated to kerman university of medical sciences.   methods: this cross-sectional descriptive study was conducted in various wards and units of four hospitals affiliated to kerman university of medical sci...
