Incised valley fills are complex as they correspond to multiple sea-level cycles which makes interpretation and correlation of stratigraphic surfaces fraught with uncertainty. Despite numerous studies the stratigraphy incised fills, few have focused on extensive core coverage linked high fidelity dating in a macro-tidal, tide-dominated setting. For this study nineteen sediment cores were drille...

Widely used workload sources such as Parallel Workloads Archive (PWA) [4] or Grid Workloads Archive (GWA) [5] often provide data sets that are still unrealistic. Typically, very limited information is available about the grid/cluster parameters such as architecture, speed, RAM size or resource specific policies. Moreover, no information concerning background load, resource failures, or specific...

An investigation was conducted to determine the influence of recycled scrap tire rubber on the engineering properties of controlled low strength material (CLSM). With control over the ultimate compressive strength of CLSMs being key for applications such as backfilling utility trenches where re-excavation is often necessary, incorporation of scrap tire rubber into the CLSM mixture is a viable w...

In this paper, we evaluate the performance implications of using a buddy scheme for contiguous node allocation, in conjunction with a backfilling job scheduler for clusters. When a contiguous node allocation strategy is used, there is a trade-off between improved run-time of jobs (due to reduced link contention and lower communication overhead) and increased wait-time of jobs (due to external f...

This paper proposes a two-level scheduler for dynamically scheduling a continuous stream of sequential and multi-threaded batch jobs on large-scale grids, made up of interconnected clusters of heterogeneous single-processor and/or symmetric multiprocessor machines. The scheduler aims to schedule arriving jobs respecting their computational and deadline requirements, and optimizing the hardware ...

-----------------------------------------------------------------------------ABSTRACT------------------------------------------------------------------------Hadoop is a large scale distributed processing infrastructure designed to handle data intensive applications. In a commercial large scale cluster framework, a scheduler distributes user jobs evenly among the cluster resources. The proposed ...

This paper empirically explores the advantages of the collaboration between different parallel compute sites in a decentralized grid scenario. To this end, we assume independent users that submit their jobs to their local site installation. The sites are allowed to decline the local execution of jobs by offering them to a central job pool. In our analysis we evaluate the performance of three jo...

EPS geofoam has been used for about 40 years in many geotechnical applications in many countries around the world. EPS geofoam possesses properties which are often advantageous in geotechnical construction. These include: an extremely low density, a high strength-to-weight ratio and very small or virtually zero lateral expansion under compressive loading. It has been used for backfilling retain...

The job scheduling technology is an effective way to achieve resource sharing and to improve computational efficiency. Scheduling problem has been proved to be NP-complete problems, Particle Swarm Optimization (PSO) algorithm has demonstrated outstanding performance in solving such issues. In cognizance of the characteristics of cluster scheduling problem, a schedule strategy based on PSO was d...

In this work, three samples of municipal solid waste incinerators fly ash (MSWI-FA) have been stabilized in systems containing coal fly ash to create geopolymers through a polycondensation reaction. Monolithic products have been obtained with both MSWI fly ash as received and after the partial removal of chloride and sulfate by water washing. The polycondensation products have been characterize...
