Background :Lead elements have an adverse effect on human health. The most important complications of lead poisoning are disorders of nervous system particularly seizure .This study aimed to evaluate the blood lead levels and its association with convulsion in a group of hospitalized febrile children.   Methods : In this analytic cross-sectional study, 60 hospitalized febrile children with 1-...

Security assessments are costly and time consuming and cannot be carried out from scratch each time a system is updated or modified. This motivates the need for specific methodology addressing the maintenance of assessment results, in particular, and a componentoriented approach to security assessment in general. This paper presents such a methodology in the setting of model-based security asse...

(continued on page 2) different tests. In the early days of Title I, the predecessor of Chapter 1, for example, there was an interest in being able to accumulate and compare results for districts and states that used different standardized tests. That interest spawned the massive “Anchor Test Study” in the early 1970s, that had as one of its two major purposes the development of ways to “transl...

Weldments are particularly susceptible to fracture due to defects, material property variations, and residual stresses created during the welding process. It is common in fracture assessments of welded structures to ignore these features; defects are often idealized to be crack-like, weld properties to be homogeneous, and residual stresses to be uniaxial and tensile or nonexistent. This paper p...

Perhaps the best known model of people's beliefs under uncertainty is that of subjective or personalistic probabilities. A decision theoretic justification for this model is provided by the appeal of Savage's (1954) axioms. In his theory, the objects of choice are acts, functions from a set of possible states to a set of consequences. The agent is assumed to possess preferences-formally a binar...

ion as supported by Rigi merged with the SHriMP capabilities of nested graphs would be a nice start. We have pointed out the importance of keeping focus and context while carrying operations that affect the graph structure. When having to understand small portions of large graphs, these operation features help raise model comprehension by reducing confusion by sudden changes of the layout.

Sir, Many patients come with vertigo as their presenting symptom. They have been to physicians/neurologists/ENT specialists and have been fully investigated and treated symptomatically without any positive findings or relief. On detailed probing, these patients are found to be cases of depression-mostly of retarded variety. There is no specific age, sex, domicile or socioeconomic distribution o...

A summary is given of a meeting held at Sussex University, UK, in October 2000, which allowed the exchange of ideas on methods of assessment of dose to the public arising from potential authorised radioactive discharges from nuclear sites in the UK. Representatives of groups with an interest in dose assessments were invited, and hence the meeting was called the Consultative Exercise on Dose Ass...

at the INTERACT " 99 conference. Abstract Two studies are reported that examined the reliability of human assessments of document similarity and the association between human ratings and the results of n-gram automatic text analysis (ATA). Human inter-assessor reliability (IAR) was moderate to poor. However, correlations between average human ratings and n-gram solutions were strong. The averag...

Effective robotic simulation depends on accurate modeling of physics and the environment as well as the robot, itself. This paper describes validation studies examining feature extraction, WaveLan radio performance, and human interaction for the USARSim robotic simulation. All four feature extraction algorithms showed strong correspondences between data collected in simulation and from real rob...
