A 2m-Range 711uW Body Channel Communication Transceiver Featuring Dynamically-Sampling Bias-Free Interface Front End

Body Channel Communication (BCC) offers a low-loss signal transmission medium for ultra-low-power wearable devices on human body [1]. However, the effective communication range on human body is limited to less than 1m in the state-of-the-art BCC transceivers [2], where the signal loss at the interface of body surface and BCC receiver remains to...

Success factors in the realization of large ice projects in education

There has been a long tradition in making ice structures, but the development of technical improvements for making ice buildings is a new field with just a handful of researchers. Most of the projects were realized by professors in cooperation with their students as part of their education in architecture and civil engineering. The following...

Form-finding and construction of ice composite shell structures

By using inflatable moulds and then spraying cellulose-water mixture, one ice dome and two ice towers were built in Harbin in December 2016. During the whole process, form-finding of the inflatable moulds as well as the construction of these ice composite shell structures are very important for the final results.<br/>The mould for the ice dome...

The Applications and Practices of 3D Cadastre in Shenzhen

As the economy and urbanization develop, the expansion of the city not only develops towards the horizontal space, but also towards the vertical space. Facing the development of three-dimensional (3D) space, the traditional two-dimensional (2D) cadastral management mode cannot satisfy the need of current 3D land use and urban plan, so developing...

3D cadastre in China: A case study in Shenzhen City

3D Cadastre in China - a Case Study in Shenzhen City

A rapid urban growth in China urges to extend land use to land space use in three dimensions due to limited land resource in cities. 3D cadastre is emerging as an effective means to support such a demands for using urban land in a way of three dimensions. Shenzhen, located in the south-eastern coastal region of China, as one of the most...

AMulti-jurisdiction Case Study of 3D Cadastre in Shenzhen, China as Experiment using the LADM

With the increasing urban population, and the urban exploitation and utilization, especially in the subsurface and the air, various spaces above and below each other are built and belonging to different owners or users. Although the traditional 2D cadastre still plays a dominant role in land administration, urban resource and space management,...
