Introduction Solid state (and other) sensors have a limited dynamic range D in : where both thresholds are measured in terms of the light intensity (D out is specified as the ratio of the output signals).

Sensitivity is one of the simplest and block sensitivity one of the most useful invariants of a boolean function Nisan and Nisan and Szegedy have shown that block sensitivity is polynomially related to a number of measures of boolean function complexity The main open question is whether or not a polynomial relationship exists between sensitivity and block sensitivity We de ne the intermediate n...

Sensitivity is one of the simplest, and block sensitivity one of the most useful, invariants of a boolean function. Nisan [SIAM J. Comput. 20 (6) (1991) 999] and Nisan and Szegedy [Comput. Complexity 4 (4) (1994) 301] have shown that block sensitivity is polynomially related to a number of measures of boolean function complexity. Themain open question is whether or not a polynomial relationship...

introduction: ankle fracture is one of the most common joint fractures. x-ray and physical examination are its main methods of diagnosis. recently, ultrasonography (us) is considered as a simple and non-invasive method of fracture diagnosis. this study evaluated the diagnostic accuracy of us in detection of ankle fracture in comparison to plain radiography. methods: in this diagnostic accuracy ...

background: we aimed to extract the histogram features for text analysis and, to classify the types of bio medical waste (bmw) for garbage disposal and management. methods: the given bmw was preprocessed by using the median filtering technique that efficiently reduced the noise in the image. after that, the histogram features of the filtered image were extracted with the help of proposed modifi...

objective this research was carried out to compare antibacterial effect of rosa nutkana sepal extract with synthetic antibiotics on methicillin resistant staphylococcus aureus (mrsa) bacteria isolated from patients with sty. patients and methods this descriptive study was done in 2009 at remedial center of shahid beheshti university and sampling was performed from patients suffering from sty us...

the aim of the study was to determine the resistance patterns of pseudomonas aeruginosa isolates recovered from patients with surgical wounds in hospitals and also to investigate their epidemiological relatedness using molecular typing techniques. twenty pseudomonas sp. isolated from surgical wounds were subjected to antibiotic susceptibility testing by disk diffusion, plasmid profile, sds-page...

introduction: to investigate the ultrastructural changes of dentin irradiated with 980-nm diode laser under different parameters and to observe the morphological alterations of odontoblasts and pulp tissue to determine the safety parameters of 980-nm diode laser in the treatment of dentin hypersensitivity (dh). methods: twenty extracted human third molars were selected to prepare dentin discs. ...
