Research on Medium- and Long-Term Operation Simulation Method Based on Improved Universal Generating Function

open access: yesIEEE Access, 2019
The development of technologies in generation-grid-load-energy storage has created enormous uncertainties for power system and thus brings great challenges to medium-and long-term operation simulation.

Crafting Targeted Universal Adversarial Perturbations: Considering Images as Noise

open access: yesIEEE Access, 2023
The vulnerability of Deep Neural Networks (DNNs) to adversarial perturbations has been demonstrated in a large body of research. Compared to image-dependent adversarial perturbations, universal adversarial perturbations(UAPs) is more challenging for ...

Analyzing Comprehensive QoS with Security Constraints for Services Composition Applications in Wireless Sensor Networks

open access: yesSensors, 2014
Services composition is fundamental to software development in multi-service wireless sensor networks (WSNs). The quality of service (QoS) of services composition applications (SCAs) are confronted with severe challenges due to the open, dynamic, and ...

The probability of generating a finite simple group [PDF]

open access: yes, 2013
We study the probability of generating a finite simple group, together with its generalisation PG,socG(d), the conditional probability of generating an almost simple finite group G by d elements, given that these elements generate G/ socG.

Generation of near-optimal universal Boolean functions

open access: yesJournal of Computer and System Sciences, 1970
AbstractA Boolean function U(z1, z2,…,zm) is universal for given n≥1 if it realizes all Boolean functions f(x1,…,xn) by substituting for each zj a variable of the set {0, 1, x1,…,xn, 1,…,n}). An easily applied method based on linear algebra is developed for finding universal Boolean functions having a small number m of arguments.

The complexity of small universal Turing machines : a survey [PDF]

open access: yes, 2009
We survey some work concerned with small universal Turing machines, cellular automata, tag systems, and other simple models of computation. For example it has been an open question for some time as to whether the smallest known universal Turing machines ...
