OBJECTIVES Optimum viewing conditions facilitate identification of radiographic details and decrease the need for retakes, patients' costs and radiation dose. This study sought to evaluate the effects of different viewing conditions on radiographic interpretation. MATERIALS AND METHODS This diagnostic study was performed by evaluating radiograph of a 7mm-thick aluminum block, in which 10 hole...

This paper discusses the application of Castigliano’s Theorem to a half circular beam intended for use as a shaped, tunable, passively compliant robot leg. We present closed-form equations characterizing the deflection behavior of the beam (whose compliance properties vary along the leg) under appropriate loads. We compare the accuracy of this analytical representation to that of a Pseudo Rigid...

In this paper, we present a new design of a compact tri-band unequal power divider, which is composed of a circularcoupling power divider and a triple-band resonator. The unequal power dividing characteristic is realized by two circular shaped microstrip lines coupled through a circular shaped slot. The triple-band resonator, which comprises a conventional half-wavelength resonator, a short stu...

structural analysis of remotely sensed data provides a method of assessing the structural significance of large-magnitude regional metallogenesis in the kerman porphyry cu belt in the southern part of the central iranian volcanic belt. the role of large-magnitude ring structures in the distribution of hydrothermal alteration zones and porphyry copper deposits in the southern part of the kerman ...

Box-and peanut-shaped bulges III. A new class of bulges: Thick Boxy Bulges. Abstract. Inspecting all 1224 edge-on disk galaxies larger than 2 ′ in the RC3 on Digitized Sky Survey (DSS) images (Lütticke et al. 2000a) we have found several galaxies with extraordinary bulges meeting two criteria: They are box shaped and large in respect to the diameters of their galaxies. These bulges are often di...

This paper presents hardware implementation of the data encryption and decryption of the DES standard algorithm. The design consists of the S-Box circuit Exclusive-OR circuit, Circular Left Shift circuit and the control unit. The S-Box circuit implemented using 32 PLDs (Programmable Logic Device) chip that hold substitution a 48-bits input data and yields a 32-bits output data. The other circui...

BACKGROUND For many years, the detection of clusters has been of great public health interest. Several detection methods have been developed, the most famous of which is the circular scan method. The present study, which was conducted in the context of a rare disease distributed over a large territory (7675 cases registered over 17 years and located in 1895 units), aimed to evaluate the perform...
