Realizing hard ceramic coatings on the plastic component of a joint prosthesis can be strategic for the mechanical preservation of the whole implant and to extend its lifetime. Recently, thanks to the Plasma Pulsed Deposition (PPD) method, zirconia coatings on ultra-high molecular weight polyethylene (UHMWPE) substrates resulted in a feasible outcome.(More)
We describe the hardware platform that will be used to run several demonstrator applications within the EU-funded hArtes project. hArtes' main goal is to support, with appropriate tools, the development of complex applications on heterogeneous and reconfigurable systems. Our platform provides a number of heterogeneous computing sub-systems, such as DSPs,(More)
A key tool to increase the exploitation of dynamic reconfigurable platforms is the run-time resource manager. This system module coordinates the usage of both software and reconfigurable hardware resources in the context of a multi-programmed environment, by alleviating the operating system's induced overhead. This paper introduces a two-layers run-time(More)
We propose a novel FPGA-accelerated BWA-MEM implementation, a popular tool for genomic data mapping. The performance and power-efficiency of the FPGA implementation on the single Xilinx Virtex-7 Alpha Data add-in card is compared against a software-only baseline system. By offloading the Seed Extension phase onto the FPGA, a two-fold speedup in overall(More)
Next Generation Sequencing techniques have dramatically reduced the cost of sequencing genetic material, resulting in huge amounts of data being sequenced. The processing of this data poses huge challenges, both from a performance perspective, as well as from a power-efficiency perspective. Heterogeneous computing can help on both fronts, by enabling more(More)
In joint arthroplasty one of the main issues related to the failure of prosthetic implants is due to the wear of the ultra-high molecular weight polyethylene (UHMWPE) component. Surface treatments and coatings have been recognized as enhancing methods, able to improve the tribological properties of the implants. Therefore, the main objective of this work(More)
One of the most important issues leading to the failure of total joint arthroplasty is related to the wear of the plastic components, which are generally made of ultra high molecular weight polyethylene (UHMWPE). Therefore, the reduction of joint wear represents one of the main challenges the research in orthopedics is called to address nowadays. Surface(More)
Concerning Anterior Cruciate Ligament (ACL), an overall characterization of native and synthetic specimens, used during reconstruction, is still lacking, above all focusing on their time-dependent behaviour. The main goal of this work was to implement a complete testing protocol able both to investigate pre-implant mechanical characteristics and to provide(More)
