Encoder is essential for speed control and very valuable in condition monitoring for a mine hoist and the failure in sensor measurements can lead to serious accidents.In this paper, a novel encoder fault detection, isolation and tolerant control strategy based on finite time observers and constrained fault-tolerant controller is proposed for a mine
The plastid-targeted transcription factor Whirly1 (WHY1) has been implicated in chloroplast biogenesis, plastid genome stability, and fungal defense response, which together represent characteristics of interest for the study of autotrophic losses across the angiosperms.While gene loss in the plastid and nuclear genomes has been well studied in myc

Temperate species often require or flower most rapidly in the long daylengths, or photoperiods, experienced in summer or after prolonged periods of cold temperatures, referred to as vernalization.Yet, even within species, plants vary in the degree of responsiveness to these cues.In Arabidopsis thaliana, CONSTANS (CO) and FLOWERING LOCUS C (FLC) gen
In the "Sarawak Museum Journal," volume V (1949), pages 156-166,I gave a revised account of the genus Heterogonium Presl, based on specimens in the Singapore herbarium.Dr M.A.Donk wrote subsequently pointing out that specimens at Bogor (Buitenzorg) add materially to the information contained in that paper.The present paper gives the result of a stu
