چکیده
8 9 Abstract 10 11 To verify NC programs as well as to optimize the cutting conditions, the importance of machining process simulation system is increasing. 12 The paper discusses new approach for milling operation simulation using enhanced Z map algorithm. To extract the required geometric 13 information from NC code, suggested algorithm uses supersampling method to enhance the efficiency of a simulation. By executing 14 redundant Boolean operations in a grid cell and averaging down calculated data, presented algorithm can accurately represent material 15 removal volume though tool swept volume is negligibly small. Supersampling method is the most common form of antialiasing and usually 16 used with polygon mesh rendering in computer graphics. The key advantage of extended Z map is that the data structure is same with 17 conventional Z map, though it can acquire higher accuracy and reliability with same or lower computation time. By simulating machining 18 operation efficiently, this system can be used to improve the reliability and efficiency of NC machining process as well as the quality of the 19 final product. 20 # 2002 Published by Elsevier Science B.V. 21 22

The ribosomal RNA genes encode the enzymatic scaffold of the ribosome and thereby perform perhaps the most basic of all housekeeping functions. However, recent data suggests that they might also control important aspects of cell behavior.
متن کاملProtein Misfolding, Amyloid Formation, and Neurodegeneration A Critical Role for Molecular Chaperones?
The most conspicuous feature of many neurodegenerative disorders, including Alzheimer's, Parkinson's, and Huntington's disease, is the occurrence of protein aggregates in ordered fibrillar structures known as amyloid found inside and outside of brain cells. The appearance of aggregates in diseased brains implies an underlying incapacity in the cellular machinery of molecular chaperones that nor...
متن کاملThe Relationship Between Propagation Characteristics and Nonlinearity of Cryptographic Functions
The connections among the various nonlinearity criteria is currently an important topic in the area of designing and analyzing cryptographic functions. In this paper we show a quantitative relationship between propagation characteristics and nonlinearity, two critical indicators of the cryptographic strength of a Boolean function. We also present a tight lower bound on the nonlinearity of a cry...
متن کاملA new efficient simulated annealing algorithm for the resource-constrained project scheduling problem and its multiple mode version
This paper describes new simulated annealing (SA) algorithms for the resource-constrained project scheduling problem (RCPSP) and its multiple mode version (MRCPSP). The objective function considered is minimisation of the makespan. The conventional SA search scheme is replaced by a new design that takes into account the specificity of the solution space of project scheduling problems. For RCPSP...
