We explore a variation of Jouppi's stream buuers scheme that reduces the memory stall time by prefetching lines on cache misses. In Jouppi's scheme since the stream buuers are oo-chip, a penalty is incurred even when the required line is available in the stream buuers. We propose moving the stream buuers on-chip to reduce this penalty. Also a line that hits in the stream buuer is not moved into...

surge and rotating stall phenomena are two dynamic instabilities that occur in both axial and centrifugal compressors. surge is the stream instability phenomenon in compressor that imposes severe damages to the compressors. nowadays, suppressing surge phenomenon is one of the most important issues in oil and gas industries, especially when flow reduction or gas reflux is considered. this resear...

Features of moving objects are non-retinotopically integrated along their motion trajectories as demonstrated by a variety of recent studies. The mechanisms of non-retinotopic feature integration are largely unknown. Here, we investigated the role of attention in non-retinotopic feature integration by using the sequential metacontrast paradigm. A central line was offset either to the left or ri...

Transmitters are used to pass data stream through transmission lines in either current or voltage mode. In high data rate applications, the output impedance of transmitters should match the transmission lines’ characteristic impedance and should be tunable in order to compensate the process, voltage, and temperature variations. The multiplexing technique can be used to extend transmitters signa...

We apply an eclipse mapping technique to observations of the eclipsing magnetic cataclysmic variable HU Aqr. The observations were made with the S-Cam2 Superconducting Tunnel Junction detector at the WHT in October 2000, providing high signalto-noise observations with simultaneous spectral and temporal resolution. HU Aqr was in a bright (high accretion) state (V = 14.7) and the stream contribut...

in this short article, we observe that the path of particle of mass $m$ moving along $mathbf{r}= mathbf{r}(t)$ under pseudo-force $mathbf{a}(t)$, $t$ denotes the time, is given by $mathbf{r}_d= int(frac{dmathbf{r}}{dt} mathbf{a}(t)) dt +mathbf{c}$. we also observe that the effective force $mathbf{f}_e$ on that particle due to pseudo-force $mathbf{a}(t)$, is given by $ mathbf{f}_e= mathbf{f} mat...

assiganga stream is an important tributary of bhagirathi river in central himalaya (india). the stream is characterized by heterogeneity in habitat and substratum features harboring diverse fish fauna. at present this stream is facing threat of being fragmented by the construction of two hydro-electric projects. present study aimed to study fish diversity and their habitat use in assiganga stre...

Iranians have a very long history of water harvesting to address water scarcity and the consequences of frequent droughts. Among these strategies, Bandsar is a wide spread indigenous practice, which has been utilized in the central and the southern part of Khorasan province (the northeast Iran). Bandsar in Persian means a series of consecutive bands, berms, levees, or dikes. A Bandsar consists ...
