Advanced Underwater Imaging Phase IV Annual Report FY 08 PI : Fraser
1. Rigorous test tank validation of laser pulse time history model, including experimental measurement of beam spread function over extended distances. 2. Development of a receiver model as a necessary addition to the EODES-3 software to more accurately simulate the major noise sources present in the image formation process for both pulsed and CW LLS. 3. Test tank comparison between CW LLS and ...
متن کاملTime Optimal Hybrid Sliding Mode-PI Control for an Autonomous Underwater Robot
This paper presents an underwater robot control system using combination principle among sliding mode control (SMC), Pontryagin maximum principle and linear PI control. The SMC switches according to the Pontryagin’s time optimal control principle, in which the solution is obtained by using neural network approach to yield a time optimal response at its reaching phase. PI control is used in plac...

متن کاملObservation of eta' decays to pi+pi-pi0 and pi+pi-e+e-.
Using psi(2S)-->pi;{+}pi;{-}J/psi, J/psi-->gammaeta;{'} events acquired with the CLEO-c detector at the CESR e;{+}e;{-} collider, we make the first observations of the decays eta;{'}-->pi;{+}pi;{-}pi;{0} and eta;{'}-->pi;{+}pi;{-}e;{+}e;{-}, measuring absolute branching fractions (37_{-9};{+11}+/-4)x10;{-4} and (25_{-9};{+12}+/-5)x10;{-4}, respectively. For eta;{'}-->pi;{+}pi;{-}pi;{0}, this re...
متن کاملCommuting $pi$-regular rings
R is called commuting regular ring (resp. semigroup) if for each x,y $in$ R there exists a $in$ R such that xy = yxayx. In this paper, we introduce the concept of commuting $pi$-regular rings (resp. semigroups) and study various properties of them.
