A substantial rise in the number of cancer survivors has led to urgent management questions regarding effective posttreatment imaging‐based surveillance strategies for cancer recurrence. Current surveillance guidelines provided by a number of professional societies all warn against overly aggressive surveillance, especially for low‐risk patients, but all fail to provide more specific directions to...
This paper studies the joint transmit beamforming optimization in the downlink of a single-cell multiuser distributed antenna system. Due to the distributed nature of transmit antennas, the signals received from different distributed antenna units (DAUs) will experience various transmission delays, and it is difficult to realize accurate symbol-level time synchronization at the user terminal. Thus,...
In order to offer more efficient communication service, the 3GPP group has developed the research on Long-Term Evolution system. A key factor to guarantee the quality of service (QoS) in LTE is the handover of user equipment. However, the detection method of mobile terminal in the original standards does not fit the current high-speed scene any more. To address this issue, a novel adaptive algorithm...
This paper concentrates on the mixed byproduct gases scheduling (MBGS) problem in iron and steel enterprises. The units in a typical MBGS system are categorized into five types, whose features are discussed. Then a MILP mathematical model is built to minimize the excess and the shortage of gas distribution. A hybrid algorithm combined gene algorithm (GA) and linear programming (LP) is presented based...
Dynamic multi-objective evolutionary algorithms (Dynamic MOEAs) use the evolutionary algorithms to solve the dynamic multi-objective optimization problems (DMOPs). It has become one of the hot areas of research. The challenge of DMOPs is that the objective functions, the constraints or the parameters may change over time. This paper tries to provide a comprehensive overview of the related work, which...
An intra-prediction mode with 4×4 block and 16×16 block sizes for luma component and 8×8 block size for chroma component is used in H.264 to improve the rate-distortion performance. However, the computational complexity of H.264 encoder is drastically increased due to the various intraprediction modes. Recently efficient hardware architectures were proposed for the fast execution of H.264/AVC intraprediction...
