asymmetric information in iran’s insurance market: case study for automobile insurance in iran insurance companythis research aims to test the presence of asymmetric information by using the dynamic information of automobile policyholders in the iran insurance company (iic). the conditional independence test is conducted by bivariate probit model, the dynamic properties which are presented for ...

We reviewed the recurrence rate and possible factors influencing recurrence of preauricular sinus after excision. Seventy-one patients with 73 preauricular sinuses seen at our centre from year 2000 to 2005 were reviewed in this study. The overall recurrence rate was 14.1%. Twelve sinuses needed to be drained for an abscess prior to a definitive surgery. Different modalities used in demonstratin...

The application of human immunology in solving security problems in Grid Computing seems to be a thought-provoking research area. Grid involves large number of dynamic heterogeneous resources. Manually managing the security for such dynamic system is always fault prone. This paper presents the simple immune based model for self-protection (SIMS) of grid environment from various attacks like DoS...

background and aim. the use of certain lasers has been proposed as an adjunctive method in periodontal pocket therapies. the objective of this study was to investigate the effects of nd:yag laser on the clinical periodontal parameters following scaling and root planing (srp) in comparison to spr alone. materials and methods. six adults with moderate to severe chronic periodontitis, each with at...

This research attempts to span the gap between the AI in medicine (AIM) and consistency-based diagnosis (CBD) communities by applying CBD to physiology. The highly-regulated nature of physiological systems challenges standard CBD algorithms, which are not tailored for complex dynamic systems. To combat this problem, we separate static from dynamic analysis, so that CBD is performed over the ste...

Dynamic test generation consists of running a programwhile simultaneously executing the program symbolically in order to gather constrains on inputs from conditional statements encountered along the execution. Those constraints are then systematically negated and solved with a constraint solver, generating new test inputs to exercise different execution paths of the program. This process is rep...

Software is increasingly being built through the composition of exisiting components , such as web services, where access to the source code, and in some cases even the executable code, is unavailable. The users of these components must rely on the existing documentation of the component to understand how the component should be used. However, this documentation is often imprecise or incomplete...

We study moments and asymptotic distributions of the construction cost, measured as the total displacement, for hash tables using linear probing. Four different methods are employed for different ranges of the parameters; together they yield a complete description. This extends earlier results by Flajolet, Poblete and Viola. The average cost of unsuccessful searches is considered too.
