Application Specific Instruction Processors (ASIPs) provide enhanced performance by directly implementing application segments in hardware as custom instructions. Recent work [1, 2] automates generation of custom instructions from application source code. Speedups of up to 6 times [3] are attainable for certain benchmarks. However, instructions generated from C are often restricted to small clu...

This paper describes an architecture that provides support for quality of service (QoS) in open systems. The Quartz QoS architecture aims to avoid the dependency on specific platforms that limits the application of most existing QoS architectures in open, heterogeneous and distributed systems. Quartz adopts a flexible and extensible platform-independent design that allows its internal component...

The elastic constants of a natural-quartz sphere using resonance-ultrasound spectroscopy (RUS) are measured. The measurements of the near-traction-free vibrational frequencies of the sphere are matched with the predicted frequencies from the dynamic theory of elasticity, with optimized estimates for the elastic constants driving the differences between these sets of frequencies to a minimal val...

Application of force on biomolecules has been instrumental in understanding biofunctional behaviour from single molecules to complex collections of cells. Current approaches, for example, those based on atomic force microscopy or magnetic or optical tweezers, are powerful but limited in their applicability as integrated biosensors. Here we describe a new force-based biosensing technique based o...

This paper describes an architecture that provides support for quality of service (QoS) specification and enforcement in heterogeneous distributed computing systems. The Quartz QoS architecture has been designed to overcome various limitations of previous QoS architectures that have constrained their use in heterogeneous systems. These limitations include dependencies on specific platforms and ...

Silver nanoparticles deposited on quartz substrates are widely used as SERS substrates. The nanoparticles can be deposited directly from colloidal solution by dipping technique. However, the adhesion of the particles on the quartz surface is very poor. Normally the substrate is pre-treated with hydroxylation or silanisation process. In this paper, we have demonstrated that the application of th...
