A burst-mode clock-and-data-recovery (CDR) system for a multi-channel vertical-cavity surface-emitting laser (VCSEL)-based non-return-to-zero (NRZ) optical link’s quarter-rate receivers is presented, that utilizes proxy timing recovery for fast turn-on time.The proxy timing recovery scheme takes advantage of correlated data jitter over paral
Abstract The knowledge of acoustic wave propagation in a borehole embedded in gas hydrate-bearing sediments is of great significance for the exploitation of gas hydrate.A gas hydrate-bearing sediment is a typical three-phase porous medium containing two solids and one fluid.However, until now, the borehole acoustic wavefield and its Chair Beds comp
Effective planning and management of workforce for new product development (NPD) projects is a great challenge to many organisations, especially in the presence of engineering changes during the product development process.The management objective in effective workforce management is to recruit, develop and deploy the right people at the right plac
