Multi-Robot Space Exploration: An Augmented Arithmetic Approach

open access: yesIEEE Access, 2021
Space exploration refers to constructing a map with the aid of sensor data. This exploration is achieved utilizing a group of robots in an obstacle cluttered environment and distributing tasks amongst these robot(s). The robotic configuration is equipped

A Universal Approximation Method and Optimized Hardware Architectures for Arithmetic Functions Based on Stochastic Computing

open access: yesIEEE Access, 2020
Stochastic computing (SC) has been applied on the implementations of complex arithmetic functions. Complicated polynomial-based approximations lead to large hardware complexity of previous SC circuits for arithmetic functions.

Application of the Esscher Transform to Pricing Forward Contracts on Energy Markets in a Fuzzy Environment

open access: yesEntropy, 2023
The paper is dedicated to modeling electricity spot prices and pricing forward contracts on energy markets. The underlying dynamics of electricity spot prices is governed by a stochastic mean reverting diffusion with jumps having mixed-exponential ...

Short-term frequency regulation of power systems based on DFIG wind generation

open access: yesFrontiers in Energy Research, 2022
Short-term frequency regulation is important for the safety and efficiency of power systems based on wind generation units. However, unmodeled dynamics and stochastic disturbances in wind speed and load present a challenge for frequency regulation.

Stochastic pulse coded arithmetic

open access: yes2000 IEEE International Symposium on Circuits and Systems (ISCAS), 2000
Among the different pulse codification techniques, stochastic pulse codification has its own arithmetic based on the similarity between Boolean algebra and statistical algebra. Summation and multiplication are the two basic arithmetic operations treated in depth in the literature.

Competence region estimation for black-box surrogate models

open access: yesProceedings of the International Florida Artificial Intelligence Research Society Conference, 2021
With advances in edge applications for industry andhealthcare, machine learning models are increasinglytrained on the edge. However, storage and memory in-frastructure at the edge are often primitive, due to costand real-estate constraints.

Stochastic Arithmetic Theory and Experiments

open access: yesSerdica Journal of Computing, 2010
Stochastic arithmetic has been developed as a model for exact computing with imprecise data. Stochastic arithmetic provides confidence intervals for the numerical results and can be implemented in any existing numerical software by redefining types of the variables and overloading the operators on them. Here some properties of stochastic arithmetic are

Polynomial Arithmetic Using Sequential Stochastic Logic [PDF]

open access: yesProceedings of the 26th edition on Great Lakes Symposium on VLSI, 2016
We present the design of stochastic computing systems based on sequential logic to implement arbitrary polynomial functions. Stochastic computing is an emerging alternative computing paradigm that performs arithmetic operations on real-valued data represented as random bitstreams using digital logic gates.
