We show how and why it makes sense to use a relational formalisation instead of the usual functional one in the treatment of term graphs. Special attention is paid to term graphs with bound variables, that have, to our knowledge, never been formalised with such a generality before. Besides the novel treatment of term graphs themselves, we present an innovative relational homomorphism concept th...

Ala~traet--Errors-in-variables problems are considered for the case of three variables, where the underlying relations among the noise-free variables are linear, and covariance information for the noisy variables is available. The static problem where the variables are complex (which can arise when narrowband filtering is used) is analysed in detail. Some results are also presented for the case...

The objectives of this study were to Investigate the changes in blood pressure ( systolic and diastolic) , serum lipids , glucose, electrolytes, blood cell count and weight during Ramadan fasting in apparently healthy muslem men. Eighty male college students or staffs were followed in 3 stages during the month of Ramadan. Blood pressure, weight and height were measured on day one ( baseline) ,a...

Some maps of the chaotic firefly algorithm were selected to select variables for data on blood diseases and vessels obtained from Nasiriyah General Hospital where tested tracking distribution Gamma it was concluded that a Chebyshevmap method is more efficient than Sinusoidal map through mean square error criterion.
