Performance comparison of five RNA-seq alignment tools
Aligning millions of short reads to a reference genome is a critical task in high throughput sequencing. In recent years, a large number of mapping algorithms have been developed, all of which have in common that they align a vast number of reads to genomic or transcriptomic sequences. RNA-Seq data …

A Performance Comparison Of Clustering Algorithms In Ad Hocnetworks
… hoc routing protocols. This thesis presents the performance comparison of four ad hoc network clustering protocols: Dynamic Mobile Adaptive Clustering (DMAC), Highest-Degree and Lowest-ID algorithms, and Weighted Clustering Algorithm (WCA). Yet Another Extensible Simulation (YAES) was used as the …

Performance comparison of U.K. low-energy cooling systems by energy simulation
… design documents and measured data. An excellent comparison between simulated and measured space temperatures over a one-month period demonstrates the accuracy of the model. System comparisons show that systems using free cooling from outside air and night cooling use the least energy and have the …

A Multi-City Simulation and Performance Comparison of Dynamic Ambulance Redeployment Models
… models and varying conditions then compare their performance. To evaluate performance of the redeployment models, we create the first open source simulation and optimisation package for emergency medical services, named JEMSS. The simulations run quickly, requiring less than a second to simulate …
