Xu, G. (author)Nowadays, smart sensors are widely used in a variety of application domains, such as telecommunication, health care, cars, mobile phones, smart cities. Because of limited battery capacity, low-power design is required for smart sensors. Low-voltage operation is a key leverage to reduce power consumption in smart sensors. However, uncertainties...master thesis 2015

Xu, Jin (author)Federated learning is a private-by-design distributed learning paradigm where clients train local models on their own data before a central server aggregates their local updates to compute a global model. Depending on the aggregation method used, the local updates are either the gradients or the weights of local learning models. Unfortunately,...master thesis 2022

Xu, Boliang (author)Packet communication applications cannot guarantee correct delivery of every packet. Congestions and interferences in the network lead to lost packets. However, real-time applications require timely delivery of data or information and always tolerate packet loss to achieve this aim. When some speech packets are lost, packet loss concealment (PLC...master thesis 2017

Xu, Guo (author)Depth sensing technology has developed rapidly recently due to its broad applications. Time-of-Flight (ToF) is a popular technology in depth sensing because of its advantages in high measuring accuracy and low complexity in image processing. ToF technologies are divided into two kinds: indirect time-of-flight (iToF) and direct Time-of-Flight ...master thesis 2022

Xu, Tianqi (author)In the recent years, increasing induced seismic activities have been observed in the northern part of the Netherlands due to gas extraction. These seismic events may cause severe damages to the building stock in this area, which is mainly composed of unreinforced masonry (URM) buildings not designed to withstand seismic loads. An extensive...master thesis 2018

Xu, J. (author)The oxidation and reduction kinetics of a 1.7 wt.% Mn steel alloy with 0.1 wt.% C was studied in different ?CO?_2/CO mixtures and at different temperatures. The external iron oxide growth, the internal alloying element oxide formation and the reduction of iron oxides were observed with thermogravimetry (TG). The oxidation at 750 ? follows a...master thesis 2013
