UAV-assisted MEC systems: architecture, key technology, and future challenges by Tiankui ZHANG, Yu XU, Yuanwei LIU, Dingcheng YANG, Yuanhong REN

“…With the fast deployment of 5G and the on-going development of 6G, unmanned aerial vehicle (UAV)-assisted mobile edge computing (MEC) technology has significant advantages in the terms of overcoming the geographic restrictions, addressing the computational requirements of terminal devices, and enhancing the task offloading rate of the systems, which attracts wide attentions in academia and industry.The concept and the technique advantages of the UAV-assisted MEC systems were firstly clarified, and a general UAV-assisted MEC architecture was proposed, along with the definition of each function module.Then the classic application scenarios were summarized, and the existing key techniques were sorted out, based on which the design methods for the UAV-assisted MEC were achieved.Finally, the research directions and the potential challenges in the future were prospected and clarified.…”

Golden code based transmission schemes and decoding methods for MIMO downlink system with finite-bit feedback by Sisi ZHENG, Haiquan WANG, Guobin LI, Tanming DAI

“…For a MIMO downlink system with finite-bit feedback,combined with the Golden code and the precoding technology,a new precoding design criterion and its related codeword selection method,transmissionschemes and corresponding low complexity decoding methods were proposed.In fact,based on fully utilizing the characteristics that the Golden code could overcome the channel depth fading,a double precoding matrix was constructed as transmission signals by using the selected precoding codeword,so that the decoding complexity could be reduced to linear.In the meantime,a joint ML and MMSE decoding method was proposed for the traditional transmission scheme,which could dynamically adjust the decoding complexity based on a threshold.The numerical simulation results confirm the superiority of the proposed schemes and methods.…”

New frontiers of temporary buildings. Passive housing modules by Federica Ribera, Rossella Del Regno, Pasquale Cucco

“…Architecture technology allows an industrialized modular low-cost building system, in case of an emergency – the ease and speed of the assembling process, flexibility, and immediate use – and the conditions of temporality: to create a light, removable, transportable, transformable, reusable and, at the same time, durable and adaptable to the territory’s climate and morphology building. It is a design proposal characterized by the use of passive systems which, by incorporating local resources, and recycled or recyclable materials, can guarantee the sustainability of the entire production process aiming to provide an efficient, quick and low-cost response, without neglecting architectural aspects, housing comfort and environmental impact.…”

A Universal Calculation Method for Jacobian Matrix of Parallel Mechanism by Zhang Shuangshuang, Yang Hongtao

“…The Jacobian matrix is a key concept in mechanisms and profoundly reflect the nature of the mechanism,which provides us not only a kinematics mapping relations,it also sets a basis for mechanism analysis and synthesis in the future.A universal calculation method for Jacobian matrix of parallel mechanism is presented based on screw theory.Due to its style of construction,tedious steps in normal calculation method,including observation and derivation are nicely avoided,which makes this new method much more simplified.Meanwhile,since its modularization in style,this method also provides its advantages in computer aided programming.A limited-DOF parallel manipulator 3-RPS is used as an example to testify the superiority of this method,which also set a good foundation for further performance analysis and design.…”
