in this paper the heating process in a box annealing unit is simulated and the effect of various parameters involved in the process is examined. for this purpose, the full naiver-stokes equations along with the standard k- turbulence model are solved in the fluid region using the finite volume approach. in the solid area the conduction heat transfer equation is employed using approporate surfac...

We propose an optimized visual tracking algorithm based on the real-time selection of locally and temporally discriminative features. A novel feature selection mechanism is embedded in the Adaptive Color Names [2] (ACT) tracking system that adaptively selects the top-ranked discriminative features for tracking. The Dynamic Feature Selection Tracker (DFST) provides a significant gain in accuracy...

Abstract We investigate the linear and nonlinear properties of Goldreich-Schubert-Fricke (GSF) instability in stellar radiative zones with arbitrary local (radial latitudinal) differential rotation. This may lead to turbulence that contributes redistribution angular momentum chemical composition stars. In our Boussinesq model, we varying orientation shear respect ‘effective gravity’, which desc...

M a y / J u n e 2 0 0 0 I E E E S O F T W A R E 71 This was the situation in a company I worked for some years ago: people were whispering in the corners, discussing explanations and scapegoats—half-hearted attempts to put out the fire. We were rapidly losing money and self-respect, until one manager stepped forward and admitted: “This piece of software is fatal for us. We must completely rebui...

We present a new algorithm for upper bounding the maximum average linear hull probability for SPNs, a value required to determine provable security against linear cryptanalysis. The best previous result (Hong et al. [9]) applies only when the linear transformation branch number (B) is M or (M + 1) (maximal case), where M is the number of s-boxes per round. In contrast, our upper bound can be co...

The elastic block cipher design employs the round function of a given, b-bit block cipher in a black box fashion, embedding it in a network structure to construct a family of ciphers in a uniform manner. The family is parameterized by block size, for any size between b and 2b. The design assures that the overall workload for encryption is proportional to the block size. When considering the app...

The former Soviet encryption algorithm GOST 28147-89 has been standardized by the Russian standardization agency in 1989 and extensive security analysis has been done since. So far no weaknesses have been found and GOST is currently under discussion for ISO standardization. Contrary to the cryptographic properties, there has not been much interest in the implementation properties of GOST, thoug...

Abstract To achieve logistic efficiency and customer convenience in last-mile delivery processes, a system with alternative points the form of locker box stations can be used. In such system, customers served either at their home address within certain time window, or station where parcels picked up any time. Customers get compensation payment when being box. They have request more than one par...

This paper presents a unifying theory, explaining the different relationships between firm size and export intensity that have been found in previous studies. We propose that transaction costs economies and different types of resources induce a moderating effect on the firm size and export intensity relationship. Data on international businesses in the Netherlands are used to test the theoretic...

The surface patterns of natural and experimental deposits are important as they result from the internal microstructure. For this purpose, lacunarity analysis is applied to determine heterogeneous nature deposit patterns. In study, images were digitally moved onto square mesh situation manganese dendrite on magnesite surface. relation between values box size was examined. corresponding estimate...
