Site Quality Classification Models of Cunninghamia Lanceolata Plantations Using Rough Set and Random Forest West of Zhejiang Province, China
Cunninghamia lanceolata plantations site quality classification models site quality evaluation rough set random forest
2023/12/1
The site quality evaluation of plantations has consistently been the focus in matching tree species with sites. This paper studied the site quality of Chinese fir (Cunninghamia lanceolata) plantations...

Atmospheric scientists are embarking on two new research projects supported by the U.S. National Science Foundation that involve using sophisticated planes to understand the atmospheric chemistry and ...
Private Set Relations with Bloom Filters for Outsourced SLA Validation
Bloom filters set operations set relations
2019/9/5
In the area of cloud computing, judging the fulfillment of service-level agreements on a technical level is gaining more and more importance. To support this we introduce privacy preserving set relati...
Scalable Private Set Union from Symmetric-Key Techniques
Private Set Union Private Membership Test
2019/7/4
We present a new efficient protocol for computing private set union (PSU). Here two semi-honest parties, each holding a dataset of known size (or of a known upper bound), wish to compute the union of ...
Utreexo: A dynamic hash-based accumulator optimized for the Bitcoin UTXO set
accumulators bitcoin merkle proofs
2019/6/4
In the Bitcoin consensus network, all nodes come to agreement on the set of Unspent Transaction Outputs (The “UTXO” set). The size of this shared state is a scalability constraint for the network, as ...
SpOT-Light: Lightweight Private Set Intersection from Sparse OT Extension
private set intersection OT extension
2019/6/4
We describe a novel approach for two-party private set intersection (PSI) with semi-honest security. Compared to existing PSI protocols, ours has a more favorable balance between communication and com...

Scientists set expedition investigate Iceberg Alley Antarctica
2019/11/22
The 5.4 million-square-mile Antarctic Ice Sheet is the greatest mass of fresh water on Earth. If it all were to melt, it would raise global sea levels some 220 feet. Searching for answers to how fast ...
Cheaper Private Set Intersection via Differentially Private Leakage
private set intersection differential privacy
2019/3/4
In this work we demonstrate that allowing differentially private leakage can significantly improve the concrete performance of secure 2-party computation (2PC) protocols. Specifically, we focus on the...
The Communication Complexity of Threshold Private Set Intersection
Communication Complexity Private Set Intersection
2019/3/1
Threshold private set intersection enables Alice and Bob who hold sets AA and BB of size nn to compute the intersection A∩BA∩B if the sets do not differ by more than some threshold parameter tt. In th...
