We analyze the observability properties of an underwater vehicle (moving in 2D) performing single beacon navigation for two specific classes of maneuvers, whereby the vehicle measures its distance to a fixed transponder located at a known position using an acoustic ranging device. We show that in the presence of known ocean currents, the system is found to be globally observable for constant re...

Power system state estimation is a process to find the bus voltage magnitudes and phase angles at every bus based on a given measurement set. The state estimation convergency is related to the sufficiency of the measurement set. Observability analysis actually tests this kind of problem and guarantees the state estimation accuracy. A new and useful algorithm is proposed and applied in this pape...

After a measurement, to observe the relative phases of macroscopically distinguishable states we have to “undo” a quantum measurement. We derive an inequality which is satisfied by the relative phases of macroscopically distinguishable states and consequently any desired relative phases can not be observed in interference setups. The principle of macroscopic complementarity is invoked that migh...

Wireless ranging measurements have been proposed for enabling multiple Micro Air Vehicles (MAVs) to localize with respect each other. However, the high-dimensional relative states are weakly observable due scalar distance measurement. Hence, MAVs degraded localization and control performance under unobservable conditions as can be deduced by Lie derivatives. This paper presents a nonlinear mode...

Abstract Coffee is the leading commodity of Indonesian plantations. One efforts to increase coffee production and quality requires farmers implement innovations according Good Agriculture Practices (GAP). This study aims see effect characteristics innovation on application GAP by farmers. research a survey with 100 Arabica as respondents. was conducted in Districts Lembah Gumanti Pantai Cermin....

The survey sought to establish how perceived relative advantage, computability, user friendliness and observability related to use of ICT. Quantitative data was collected from 145 teachers, 124 administrators and 175 students using a questionnaire, whose validity and reliability were assessed using Confirmatory Factor Analysis and Cronbach’s alpha respectively. Descriptive analysis was done usi...

Multiagent learning provides a promising paradigm to study how autonomous agents learn to achieve coordinated behavior in multiagent systems. In multiagent learning, the concurrency of multiple distributed learning processes makes the environment nonstationary for each individual learner. Developing an efficient learning approach to coordinate agents’ behavior in this dynamic environment is a d...
