New inputs
Unless we look anew at agriculture in terms of the balances between wider benefits and impacts and link this to current and future societal drivers, we will continue to pay lip service to the concept of sustainability without ever developing ways to achieve it, they argue. Part of the problem in facing the future is the remarkable past achievements. In recent decades there has been a huge growt...
متن کاملNew Negative Results on Differing-Inputs Obfuscation
We provide the following negative results for differing-inputs obfuscation (diO): (1) If subexponentially secure one-way functions exist then sub-exponentially secure diO for TMs does not exist (2) If in addition sub-exponentially secure iO exists then polynomially secure diO for TMs does not exist. 1 Department of Computer Science & Engineering, University of California San Diego, 9500 Gilman ...
متن کاملEfficiency of DMUs in Presence of New Inputs and Outputs in DEA
Examining the impacts of data modification is considered as sensitivity analysis. A lot of studies have considered the data modification of inputs and outputs in DEA. The issues which has not heretofore been considered in DEA sensitivity analysis is modification in the number of inputs and (or) outputs and determining the impacts of this modification in the status of efficiency of DMUs. This pa...
متن کاملA New Approach to Discrete Logarithm Problem with Auxiliary Inputs
Embedding an element of a finite field into auxiliary groups such as elliptic curve groups or extension fields of finite fields has been useful tool for analysis of cryptographic problems such as establishing the equivalence between the discrete logarithm problem and Diffie-Hellman problem or solving the discrete logarithm problem with auxiliary inputs (DLPwAI). Actually, Cheon’s algorithm solv...
متن کاملNew properties of sigma-delta modulators with DC inputs
We derive new properties of the singleand doubleloop sigma-delta modulators with constant inputs, by exploiting the inherent structure of the output sequences or codewords that the modulators are capable of producing. Specifically, we first derive upper bounds of O(.Y2) and O(-Y3) on the number of r -b i t codewords for the single and double-loop modulators, respectively. We then derive analyti...
