In this paper, we shall show some common guidelines which we can use to design parallel algorithms under the single-channel broadcast communication model. We use several graph problems as a vehicle. The graph problems we solve include topological ordering, the connected component problem, breadth-first search, and depth-first search. If an ideal conflict resolution scheme is used, all of our al...

In a recent breakthrough paper [M. Braverman, A. Garg, D. Pankratov, and O. Weinstein, From information to exact communication, STOC’13 Proceedings of the 2013 ACM Symposium on Theory of Computing, ACM, New York, 2013, pp. 151–160.] Braverman et al. developed a local characterization for the zero-error information complexity in the two party model, and used it to compute the exact internal and ...

pulse oximetry measures the relative concentration of arterial oxygenated hemoglobin and reduced hemoglobin. this paper presents the design of a pulse oximeter, which measures the presence of a third substance, carboxyhemoglobin (hbco), by unfiltered leds at 660 nm, 810 nm, and 940 nm. background information is given on the theory of pulse oximetry. theoretical approximations and calculations w...

In this paper the conjugate gradient (CG) method is employed for identifying the parameters of crack in a functionally graded beam from natural frequency measurement. The crack is modeled as a massless rotational spring with sectional flexibility. By using the Euler-Bernoulli beam theory on two separate beams respectively and applying the compatibility requirements of the crack, the characteris...

in many autonomous mobile applications, robots must be capable of analyzing motion of moving objects in their environment. duringmovement of robot the quality of images is affected by quakes of camera which cause high errors in image processing outputs. in thispaper, we propose a novel method to effectively overcome this problem using neural networks and kalman filtering theory. thistechnique u...

scattering of an incoming wave train by a discontinuity at the upper surface of the ocean over a uniform porous bottom of finite depth is considered here in the framework of linearized water wave theory. by employing residue calculus method, the reflection and transmission coefficient are obtained. these coefficients are computed numerically for different values of the porosity parameter g and ...

In 2012 August 11 (12:23 UTC) a moderate earthquake with MW=6.4 (USGS) occurred between Ahar and Varzaghan towns in Azarbayjan Province at northwest of Iran. After eleven minutes another earthquake shook the area with MW=6.2 (USGS). These consecutive earthquakes followed by intensive sequences of aftershocks whereas the strongest one had MW=5.3 (USGS). In data processing including depth modific...

background: pain control during and after surgeries can reduce subsequent complications, improve the recovery period of the patient after the surgery and immediately after discharge from the hospital, and shorten the length of stay in the hospital. objectives: the present research aimed to study the relationship between the depth of anesthesia and severity of pain after general anesthesia. meth...
