A Review: Novel Protocol for Clumping in Mobile Ad hoc Networks
"... ABSTRACT: Mobile ad hoc networks (MANETs) is the combination of three words 1. Mobile(Movable or Transportable) 2. Adhoc( Temporary or for specific purpose) 3. Networks(Flexib le data applications which use networks to communicate) o r A MANET can be defined as a system of autonomous mobile nodes t ..."

Mobile adhoc network is a type of ad hoc network that can change locations and configure itself on the fly. Base station plays a very important role
Is the Broad-Line Region Clumped or Smooth? Constraints from the Hα Profile in NGC 4395, the Least Luminous Seyfert 1 Galaxy
, 2005
"... The origin and configuration of the gas which emits broad lines in Type I active galactic nuclei is not established yet. The lack of small-scale structure in the broad emission-line profiles is consistent with a smooth gas flow, or a clumped flow with many small clouds. An attractive possibility for ..."

Unnoticeable Jitter in ATM Workstation Configurations
"... We evaluate the variation of inter-cell arrival times, namely jitter, as seen by a workstation. We present experimental results of actual jitter measurements on the FORE ASX200BX switch and a Pentium workstation running Linux. We analyze how the ATM network card device driver on a workstation pe ..."

perceives the jitter introduced by the network. We conclude from our data that the cell clumping that takes place at the ATM network card often negates any jitter introduced by the network. These findings contradict conventional analytical evaluations that claim that jitter significantly affects real
Revista Mexicana de Astronomía y Astrofísica, 42,??–?? (2006) SHADOWS AND PHOTOEVAPORATED FLOWS FROM NEUTRAL CLUMPS EXPOSED TO TWO IONIZING SOURCES
, 2005
"... Glóbulos neutros sumergidos en regiones HII son frecuentemente encontrados en regiones de formación estelar. En este trabajo investigamos la formación de regiones de sombra detrás de glóbulos neutros iluminados por el flujo ionizante directo de dos estrellas. Utilizamos una aproximación analítica, l ..."

CARDIAC GAP JUNCTION CONFIGURATION AFTER AN UNCOUPLING TREATMENT AS A FUNCTION OF TIME
"... Rabbit ventricle either was fixed in glutaraldehyde without injury (control) or was injured before fixation, presumably causing electrical uncoupling of the gap junctions. All tissue was then processed for freeze-fracture. Replicas of control gap junctions exhibited irregular packing of the Mace par ..."

Within the clumps, the particles and pits were hexagonally packed and the center-to-center spacing of the particles averaged 9
Intra node parallelization of MPI programs with OpenMP
, 1998
"... The availability of multiprocessors and high performance networks offer the opportunity to construct CLUMPs (Cluster of Multiprocessors) and use them as paxallel computing platforms. The main distinctive feature of the CLUMP axchitecture over the usual paxallel computers is its hybrid memory model ..."

Massively Parallel Individually Selecting Configuration Interaction: A Progress Report
, 2001
"... this report (see ) so that only the most important points are summarized here. The B 2 photoelectron spectrum originates right at the onset of the nonadiabatic regime (the B 2 cusp occurs 0.08 eV above to the minimum of the B 2 electronic state) and it is highly sensitive to ..."

Investigating the performance of two programming models for clusters of SMP PCs
, 2000
"... Multiprocessors and high performance networks allow to build CLUsters of MultiProcessors (CLUMPs). A main distinctive feature over traditional parallel computers is their hybrid memory model (message passing between the nodes and shared memory inside the nodes). We eval- uate the performance of a ..."

236 Progress of Theoretical Physics Supplement No. 162, 2006 Dynamics of Two-Sign Point Vortices in Positive and Negative Temperature States
"... Dynamics of two-sign point vortices in positive and negative temperature states is ex-amined by a special-purpose supercomputer (MDGRAPE-2). Temperature T is determined by random sampling of 107 states for microcanonical ensemble in which system energy and angular impulse are kept constant. Distribu ..."

The boost factors, corresponding to an enhancement of the signal—linked to the clumpiness properties of the dark matter distribution—, have been taken as high as ..."
