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...
