With the complexity big data platform architectures, data engineer provides the infrastructure with computation and storage resource for data scientist and data analyst. With those supports, data scientists can focus their domain problem and design the intelligence module (e.g., prepare the data, select/train/tune the machine learning modules and validate the result). However, there is still a gap...
Inertial sensors for pedestrian dead-reckoning (PDR) have been attracting considerable attention recently. Since accelerometers are prone to the accumulation of errors, a “Zero Velocity Update” (Z-UPT) technique [1], [2] was proposed as a means to calibrate the velocity of pedestrians. However, these inertial sensors must be mounted on the bottom of the foot, resulting in excessive vibration and errors...
In traditional advertisement push/broadcast applications, a lot of advertisement files will be directly downloaded from telcom operators (or content providers) to subscribers, and more bandwidth resources are needed. However, the server's upload bandwidth might be the performance bottleneck when many files are downloaded at meanwhile. It results in network congestion, incompletely received files and...
