PLACE, CULTURE, TIME—DESIGN IN DRASTICALLY CHANGING CHINA

Architecture is a microcosm of the times. In the past three decades when China experienced massive urbanization, the architectural market also developed from scratch, then grew and expanded explosively. He Jingtang, who has been leading his team practicing the architectural design in the market from the very beginning of the urbanization movement, witnessed the drastic changes in China over the past three decades, and every architecture they create reflects profound thoughts on place, culture and time. This exhibition presents his architectural philosophy and works in the past decades, which, despite of the variation of places and custom, keeps abreast with the time and provokes thoughts on future urban development.

Since its inauguration in IUAV University Venice in October 2016, the exhibition has toured around China and been on display at some of the most prestigious Chinese universities, including Tongji University, Peking University, Harbin Institute of Technology and Southwest Jiaotong University. Now at the invitation of UC Berkeley, the exhibition aims to bridge over the east and west and promote dialogue and communication between the two countries.

The exhibition presents the enriched contents of different architectural typologies including museum, memorial hall, university campus and old town renewal, as well as the remarkable professional practices of He Jingtangand his team on the vast land of China. With models, images, videos and texts, the exhibition elaborates the creative thinking of He Jingtang and his team on different geographical contexts, cultural features and historical background. It also showcases, from the perspectives of theory, team building and educational concept, lessons and experiences drawn from the team’s years of practice, research and education on specific design projects.

ABOUT HE JINGTANG

Professor He Jingtang has put forward the “2 Views” (the whole view and the sustainable development view) and “3 characters” (local character, cultural character and epochal character) on architecture philosophy and innovative thought, which are represented in many architectural works. He has been in charge of more than 100 important projects of architecture engineering design which earned him more than 40 excellent design awards from the state, department and province, including 1 golden medal, 2 silver medals, 2 copper medals, 13 first prizes, and 14 second prizes. His masterpieces include Mausoleum of the Nanyue King of the Western Han Dynasty, Metropolitan Square, China Mayors Plaza, SCUT Shaw Building of Humanities, the Sea Battle Museum of the Opium War Museum, Shenzhen Building of Science, Foshan Electric Power Mansion, the main building of the new campus of Zhejiang University, Nanhai College of South China Normal University, Chongqing University, Jiangnan University, Guangzhou Higher Education Mega Center, Beijing Olympic Badminton and Wrestling Gymnasium, 9.18 Memorial, and more.

          Throughput Maximization for UAV-Enabled Wireless Powered Communication Networks. (arXiv:1801.04545v4 [cs.IT] UPDATED)      Cache   Translate Page      

Authors: Lifeng Xie, Jie Xu, Rui Zhang

This paper studies an unmanned aerial vehicle (UAV)-enabled wireless powered communication network (WPCN), in which a UAV is dispatched as a mobile access point (AP) to serve a set of ground users periodically. The UAV employs the radio frequency (RF) wireless power transfer (WPT) to charge the users in the downlink, and the users use the harvested RF energy to send independent information to the UAV in the uplink. Unlike the conventional WPCN with fixed APs, the UAV-enabled WPCN can exploit the mobility of the UAV via trajectory design, jointly with the wireless resource allocation optimization, to maximize the system throughput. In particular, we aim to maximize the uplink common (minimum) throughput among all ground users over a finite UAV's flight period, subject to its maximum speed constraint and the users' energy neutrality constraints. The resulted problem is non-convex and thus difficult to be solved optimally. To tackle this challenge, we first consider an ideal case without the UAV's maximum speed constraint, and obtain the optimal solution to the relaxed problem. The optimal solution shows that the UAV should successively hover above a finite number of ground locations for downlink WPT, as well as above each of the ground users for uplink communication. Next, we consider the general problem with the UAV's maximum speed constraint. Based on the above multi-location-hovering solution, we first propose an efficient successive hover-and-fly trajectory design, jointly with the downlink and uplink wireless resource allocation, and then propose a locally optimal solution by applying the techniques of alternating optimization and successive convex programming (SCP). Numerical results show that the proposed UAV-enabled WPCN achieves significant throughput gains over the conventional WPCN with fixed-location AP.

          Landing pattern for RTL in VTOL UAVs      Cache   Translate Page      

@moreba wrote:

Hello ,
In the vtol drones, when RTL start at high altitudes, the drone reaches the top of the home at high altitude and the Battery consumption is too much in order to discend in the MC mode.
I have an professional idea for RTL. This idea needs to change in autopilot code and the Qgroundcontrol software . we can design a landing pattern such as a fixed wing landing pattern using the software. The UAV must returns to a loiter(altitude) waypoint in FW mode ,Then when it’s reach to direction of home, it must at that altitude start the transition to to MC and reach to the top of the home. Then reduce the altitude to Land .
In this landing pattern we can define this parameters:
1- distance(to Land point) and heading of loiter waypoint
2- loiter altitude
3- landing waypoint

A toy? Perhaps but not just one. I suspect there are a lot of applications for off-the road high speed logistics/travel- military? UAV technology has grown from "toy" helicopters; innovation is an attitude of mind - often grasping ideas (possibly new) that are in plain sight.

          PSA: This is what happens when a drone hits the wing of an airplane      Cache   Translate Page      

The University of Dayton Research Institute (UDRI) has published a video showing the damage caused by a consumer drone when it strikes the wing of a fixed-wing aircraft. The test simulated life-like conditions, the end result mimicking the collision of a quadcopter with the wing of an aircraft at 383km/h (238mph).

Despite weighing only 952g (2.1lbs), the drone tore a large hole in the wing, ultimately causing damage to its main spar. UDRI's group leader for impact physics Kevin Poormon said in a university release that the drone caused "significant damage" to the structure. Both the video and test results were recently presented at the Unmanned Systems Academic Summit.

The test follows decades of bird-strike research involving aircraft, the data necessary in a world where consumer drone numbers have skyrocketed. Talking about the topic, Poormon explained:

Drones are similar in weight to some birds, and so we’ve watched with growing concern as reports of near collisions have increased, and even more so after the collision last year between an Army Blackhawk helicopter and a hobby drone that the operator flew beyond his line of site.

Earlier this year, a video surfaced of a drone pilot operating their UAV directly above a passenger jet as it left McCarran International Airport in Las Vegas. Similar reports of reckless activity have surfaced in recent months, such as an investigation into a possibly drone-related helicopter crash earlier this year and a drone-plane collision in Canada late last year.
