T he work presented in this paper intends to apply neuro-fuzzy methods for the modeling and prediction on trac intensity of digital video sources which are coded with hybrid Motion Compensation/Di€erential Pulse Code Modulation/Discrete Cosine Transform (MC/DPCM/DCT) algorithm. Although current coding standards recommend constant bit rate (CBR) output by means of a smoothing bu€er, the hybrid ...

Einstein's eld equations for spatially self-similar locally rotationally symmetric perfect uid models are investigated. The eld equations are rewritten as a rst order system of autonomous ordinary di erential equations. Dimensionless variables are chosen in such a way that the number of equations in the coupled system of di erential equations is reduced as far as possible. The system is subsequ...

We describe a novel formulation of the range recovery problem, based on computation of the di erential variation in image intensities with respect to changes in camera position. The method uses a single stationary camera and a pair of calibrated optical attenuation masks to directly measure this di erential quantity. The subsequent computation of the range image is simple and should be suitable...

The paper deals with the calculation of the optimal traverse speed for diff erent types of materials, which is very important for predication, imaginings and dimensioning of technological factors and selection of the materials with the aim to increase of surface quality at abrasive waterjet cutting (AWJ) technology. The surface irregularities of the experimental used materials AISI 304, AISI 30...

Authors have introduced a quasidi erential signaling system, which is the method to realize low EMI (electromagnetic interference) transmission by matching the degree of imbalance of a line, a driver and a load. In this paper, authors present the measurement result of a common-mode current flowing on a transmission line, which has a narrow return trace. As a result, we confirm the e ectiveness ...

This paper considers the security of iterated block ciphers against the di erential cryptanalysis introduced by Biham and Shamir Di erential cryptanalysis is a chosen plaintext attack on secret key block ciphers that are based on iterating a cryptographically weak function r times e g the round Data Encryption Standard DES It is shown that the success of such attacks on an r round cipher depend...

Patient summary: After the introduction of systemic targeted therapies, the use of nephrectomy in patients with metastatic renal cell carcinoma has declined. Currently, systemic therapy is offered to more patients first as a means to select those candidates that will likely benefit from removal of their primary tumour. Although studies consistently demonstrate a survival benefit after nephrecto...

In September, 2009, a 20-year-old previously healthy woman presented to our emergency department with altered mental status, right arm tingling and numbness, and a bilateral pulsating frontotemporal headache. Her symptoms had started several hours earlier with transient loss of consciousness. On examination, she was alert, with reduced concentration, incoherent thoughts, and poor recall for rec...

The partial di erential equations describing the evolution of thin liquid lms on solid substrates in lubrication approximation are highly non-linear. Thus, the classical semi-implicit time integrator with a constant linear part fails due to a strong variation of the Jacobian between two consecutive time-steps. We propose to integrate the equations using an exponential propagation. This method r...
