the large complex scenes is presented in this paper. The local Z-buffering originates from the depth complexity based scene decomposition and following multistage rendering. In a naïve local Z-buffering, a large complex scene is decomposed into a low depth complexity scene and high depth complexity scene by computing a partition plane in the view space; the low and high depth complexity scenes ...

In this paper we present a routing scheme which is extremely suited for use in massively parallel systems . The routing algorithm is fault-tolerant so that network failures will not stop the system. For reasons of scalability, the routing information is extremely compact, also when the network is injured . The wormhole routing technique guarantees very low routing latency . Moreover the routing...

(La,Sr)MnO3 (LSMO) nanolayers with various crystallographic textures were grown on the sapphire substrate with and without In2O3 epitaxial buffering. The LSMO nanolayer with In2O3 epitaxial buffering has a (110) preferred orientation. However, the nanolayer without buffering shows a highly (100)-oriented texture. Detailed microstructure analyses show that the LSMO nanolayer with In2O3 epitaxial...

One of the most challenging aspects to designing a Java messaging system for HPC is the intermediate buffering layer. The lower and higher levels of the messaging software use this buffering layer to write and read messages. The Java New I/O package adds the concept of direct buffers, which—coupled with a memory management algorithm—opens the possibility of efficiently implementing this bufferi...

One of the most important items for better file system performance is efficient buffering of disk blocks in main memory. Efficient buffering helps to reduce the widespeed gap between main memory and hard disks. In this buffering system, the block replacement policy is one of the most important design decisions that determines which disk block should be replaced when the buffer is full. To o...

Database buffering normally assumes that a proper measure of performance is the number of pages transferred. This paper justifies that the number of I/O’s is the proper unit of measure. From this we derive a buffering policy that improves over known buffering policies for nested loop joins, we derive some buffering policies for hashing joins, and we make an observation about selections and quer...

Clearance is the practical limit on drug action. Here we propose a means of slowing clearance, thereby extending drug lifetime in vivo by "antibody buffering." In this process, a drug and an anti-drug antibody are coadministered. Most of the drug is bound to the antibody, preventing the drug from acting, but also preventing its elimination. A dynamic free drug pool is established by reversible ...

Recently, P2P streaming techniques have been a promising solution to a large-scale live streaming system because of their high scalability and low installation cost. In P2P live streaming systems, however, it is difficult to manage peers’ buffers effectively, because they can buffer only a limited amount of data around a live broadcasting time in the main memory and suffer from long playback la...
