Industries and laboratories heavily rely upon temperature-controlling technology due to the dependencies of their systems on temperature. Therefore, temperature control were implemented maintain stability in those systems, including batch processes. This research aimed propose test a novel method for liquid system using Fuzzy Neo which has simpler fuzzy rule inference compared previous methods....
When two objects are presented in rapid succession, observers find it difficult to discriminate their temporal order. Below certain limit (e.g., 20-70 ms), the rate of correct temporal order judgement is reported to be about 50% (i.e., close to chance level). However we have found stimulus conditions where order discrimination drops significantly below chance level: the stimulus that is present...
self-association of alcohols; including ethanol, methanol, cyclopentanol and octanol in separate mixtures with inert solvents have been studied using ft-ir spectroscopy. except for the band at 3640 cm–1 in the ir spectrum of the alcohols which is due to the monomer species, the presence of other bands in the region of stretching vibrational frequencies of oh (3100-3700 cm–1) are attributed to t...
2,5,10,13-tetraazatricyclo [12,2,2,26,9] icosa-1(16),6,8,14,17,19-hexene-3,4,11,12-tetraone tetraoxime (1a) and 2,5,11,14-tetraazatricyclo [13,3,1,16,10] icosa-1(19),6,8,10(20),15,17-hexaene-3,4,12,13-tetraonetetraoxime (1b) were obtained from condensation of 1,4- and 1,3-phenylendiamine with dichloroglyoxime, respectively. the reaction of 1,2-phenylendiamine with dichloroglyoxime resulted in t...
Near the end of 2001 February, the black-hole candidate (BHC) GRS 1758–258 made an abrupt transition from a standard hard (low) state to a soft state. Unlike Cyg X–1 and other BHCs, whose luminosity increases during this transition, GRS 1758–258 was dimmer after the transition. We present observations with the Proportional Counter Array on the Rossi X-ray Timing Explorer and interpret the pheno...
We report the discovery of a widely separated (258&farcs;3+/-0&farcs;4) T dwarf companion to the Gl 570ABC system. This new component, Gl 570D, was initially identified from the Two Micron All-Sky Survey. Its near-infrared spectrum shows the 1.6 and 2.2 µm CH4 absorption bands characteristic of T dwarfs, while its common proper motion with the Gl 570ABC system confirms companionship. Gl 570D (M...
