Factors affecting pre-failure instability of sand under plane-strain conditions by Wanatowski, D., Chu, Jian

“…However, this type of instability is different from the runaway type of instability observed under undrained conditions, and has therefore been called conditional instability. Despite the differences, the conditions for both types of instability are the same for contractive sand. …”

Efficient Deployment of Base Stations in Wireless Communication Networks by Li, Zimao, Wang, Yingying, Ma, Maode

“…This is so-called bottleneck Steiner tree problem, which also has applications in VLSI routing, WDM optical networks design and phylogenetic tree reconstruction. The problem has been proved to be NP-hard and cannot be approximated in the performance ratio 2 in polynomial time in both Euclidean and rectilinear plane and approximation algorithms in the best possible performance ratios presented for the problem in both planes. …”

Hybrid Federalization in India, Sri Lanka and Nepal by Allison-Reumann, Laura, He, Baogang

“…The five previous constitutions of Nepal failed and did not manage to avoid discrimination or overcome the domination of the majority ethnic group (Lawoti, 2007), and agreements with and principles for different members of society have not always been adhered to or delivered (Hachhethu, 2009). For more than 60 years Nepal has struggled to find appropriate solutions to problems of development, democracy, peace and equality (Von Einsiedel, Malone and Pradhan, 2012) and its new constitution has proffered a new direction for Nepal, albeit with continued contestation and disagreement.…”
