Oblivious polynomial evaluation is a protocol involving two parties, a sender whose input is a polynomial P, and a receiver whose input is a value $\alpha$. At the end of the protocol the receiver learns $P(\alpha)$ and the sender learns nothing. We…

simple and common parallel algorithm building block is the all-prefix-sums operation. In this chapter, we define and illustrate the operation, and we discuss in detail its efficient implementation using NVIDIA CUDA. Blelloch (1990) describes all-pref…

本文记录阅读该论文的笔记. 本文基于阈值加法同态加密方案提出了一个新的允许\(N\)方检查其输入集的交集是否大于\(n-t\)的IPSI方案,该协议的通信复杂度为\(O(Nt^2)\). 注意:\(N\)指的是多少个参与方.\(n\)是输入集的大小.\(t\)是预先设定的阈值,也是阈值. 该方案基于The Communication Complexity of Threshold Private Set Intersection-2019:解读进行的改进. 该协议可以用于各方知道交集很大,但不知…

OpenCASCADE Interpolation - Lagrange eryar@163.com Abstract. Power basis polynomial is the most simple polynomial function. It also be called power series. OpenCASCADE provides basic computation functions for polynomial functions, such as evaluate th…

1 Fundamentals A polynomial is either zero, or can be written as the sum of one or more non-zero terms. The number of terms is finite. A term consist of a constant coefficient and a monomial, that is, the product of zero or more variables. Each varia…

案例背景:公司从意大利购买了一套中控系统,前期我也没有参与其中(包括安装.实施都是第三方),直到最近项目负责人告诉我:前期谈判以为是数据库的License费用包含在合同中,现在经过确认SQL Server 数据库的License需要我们这边提供.等我连接到该数据库服务器检查时,发现数据库版本为2012 Enterprise Evaluation Edition (64-bit),而公司现在只购买了2012 Standard Edition .那么我现在需要安装SQL SERVER 2012 St…

There are many evaluation measures available like entropy, recall, precision, F-measure, silhouette co-efficient, purity, inverse purity for improving cluster's accuracy, efficiency and result. 1. Recall=A/(A+B), where A is the true positive, B is th…
