In the past decade, micro-electromechanical systems (MEMS)-based thermoelectric infrared (IR) sensors have received considerable attention because of the advances in micromachining technology. This paper presents a review of MEMS-based thermoelectric IR sensors. The first part describes the physics of the device and discusses the figures of merit. The second part discusses the sensing materials, thermal isolation microstructures, absorber designs, and packaging methods for these sensors and provides examples. Moreover, the status of sensor implementation technology is examined from a historical perspective by presenting findings from the early years to the most recent findings.

An experimental study is conducted on several retro-reflective beamforming schemes for wireless power transmission to multiple wireless power receivers (referred to herein as "targets"). The experimental results demonstrate that, when multiple targets broadcast continuous-wave pilot signals at respective frequencies, a retro-reflective wireless power transmitter is capable of generating multiple wireless power beams aiming at the respective targets as long as the multiple pilot signals are explicitly separated from one another by the wireless power transmitter. However, various practical complications are identified when the pilot signals of multiple targets are not appropriately differentiated from each other by the wireless power transmitter. Specifically, when multiple pilot signals are considered to be carried by the same frequency, the wireless power transmission performance becomes heavily dependent on the interaction among the pilot signals, which is highly undesirable in practice. In conclusion, it is essential for a retro-reflective wireless power transmitter to explicitly discriminate multiple targets' pilot signals among each other.

Faster fog-aided private set intersectionwith integrity preserving None

Private set intersection (PSI) allows two parties to compute the intersection of their private sets while revealing nothing except the intersection. With the development of fog computing, the need has arisen to delegate PSI on outsourced datasets to the fog. However, the existing PSI schemes are based on either fully homomorphic encryption (FHE) or pairing computation. To the best of our knowledge, FHE and pairing operations consume a huge amount of computational resource. It is therefore an untenable scenario for resource-limited clients to carry out these operations. Furthermore, these PSI schemes cannot be applied to fog computing due to some inherent problems such as unacceptable latency and lack of mobility support. To resolve this problem, we first propose a novel primitive called “faster fog-aided private set intersection with integrity preserving”, where the fog conducts delegated intersection operations over encrypted data without the decryption capacity. One of our technical highlights is to reduce the computation cost greatly by eliminating the FHE and pairing computation. Then we present a concrete construction and prove its security required under some cryptographic assumptions. Finally, we make a detailed theoretical analysis and simulation, and compare the results with those of the state-of-the-art schemes in two respects: communication overhead and computation overhead. The theoretical analysis and simulation show that our scheme is more efficient and practical.

Contribution of Design Innovation to Oriental Pearl Tower & Menara Jakarta

Strategic Study of CAE 1999, Volume 1, Issue 1, Pages 30-35
The project Oriental Pearl Tower, 463.85 m in height, ranked the first in Asia and the third in the world, has attracted millions´ visitors and been publicly recognized as the most important landmark of Shanghai. The project Menara Jakarta, 558 m in height with total floor area of 320 000 m2 is going to be the number one in the world. The pile work of Menara Jakarta has already been completed soon after construction commencement in January 1998. However, the project has to be interrupted due to the intenational financial crisis.
The success in both Shanghai Oriental Pearl Tower construction and the design competition of Menara Jakarta should be greatly attributed to the design innovation not only in architecture, but also in structure and other disciplines through the whole project from design concept to details. In the project of Shanghai Tower, designers used a string of pearls to symbolize Shanghai, hanging on a mega space frame with a sets of diagonal struts, which breaks out the traditional system of single tube to be commonly used for concrete TV tower.Therefore, a unique architecture was formed for the city landmark. Such kind of structure is also beneficial for wind and seismic resistance. Furthermore, a series of advanced technologies were employed in the tower, such as to use a prestressed concrete shell to support the 50m sphere, to use bi-hanging steel structure for the45m sphere and to design the antenna pole by using climb-up method after integrated on the ground etc. All of these innovations in design ingeniously and rationally solved a lot of problems for such complicated structure, so that the difficult construction work became easy.
In the project of Menara Jakarta, designers kept and developed all advantages and overcome some shortages in Shanghai Tower. Many new innovations were further made. Therefore the tower becomes simple, straight forward and elegant.In order that the technology innovations were based on solid science, series experimental studies in seismic engineering, wind engineering and static loading had carefully been done for Shanghai Tower, and some studies had been done for Menara Jakarta.
