BACKGROUND Direct-to-patient research via Web-based questionnaires is increasingly being used. Missed data or delayed reporting of data may negatively affect the quality of study results. It is insufficiently known to what degree patients adhere to agreed self-assessment schedule over the long term and whether questionnaires are filled out in a timely manner. OBJECTIVE The objective of this s...

This article is concerned with stability analysis of a linear discrete-time dynamic quantizer system with packet loss. First, several modifications are made to the original dynamic quantizer to make it easier to realize. Then communication channel subject to packet loss of Bernoulli distribution from the quantizer to the plant input is considered. Moreover, based on Lyapunov function approach, ...
