Non-thermal atmospheric pressure plasma jet and its application for polymer treatment
Non-thermal atmospheric pressure plasma jet is a suitable source for polymer treatment. The main characteristic of this plasma jet is the remote operation and its scalable dimension, thus, allowing local treatment of 3D surfaces. In this work an atmospheric pressure DBD plasma jet has been constructed and the application of the plasma jet for polymer treatment is investigated
IDENTIFIKASI SENYAWA METABOLIT SEKUNDER PADA TANAMAN RUMPUT KEBAR (Biophytum petersianum Klotzsch)
Grass crop kebar (Biophytum petersianum Klotzsch), included in family Oxalidaceae. This crop as according to it’s the name, of course grows either in region Kebar Tengah and Kebar Timur, glorious Manokwari Irian. Grass Kebar (Biophytum petersianum Klotzsch) many applied as drug \ud
crop between it for uterine fertility, stomachache drug, back ache drug, laxative and tumor drug. \ud
This research aim to know secodary metabolit types which implied in grass plant kebar (Biophytum petersianum Klotzsch). Research type applied is qualitative research having the character of descriptive. Material applied in this research is all part of crop Biophytum \ud
petersianum Klotzsch which dry. In determination of secodary metabolit content type which implied in crop Biophytum petersianum Klotzsch applies method spot test while determination of secodary metabolit content type standing in reproduction at crop grass kebar (Biophytum \ud
petersianum Klotzsch) applied method KLT (Thin layer chromatography) \ud
Based on result of inferential research that in crop grass kebar (Biophytum petersianum Klotzsch), contains type secodary metabolit type Flavonoid, Fenolik and alkaloid,dan generation compound isoflavon that is daidzein
Full design of fuzzy controllers using genetic algorithms
This paper examines the applicability of genetic algorithms (GA) in the complete design of fuzzy logic controllers. While GA has been used before in the development of rule sets or high performance membership functions, the interdependence between these two components dictates that they should be designed together simultaneously. GA is fully capable of creating complete fuzzy controllers given the equations of motion of the system, eliminating the need for human input in the design loop. We show the application of this new method to the development of a cart controller
Orthogonal series estimation of the pair correlation function of a spatial point process
The pair correlation function is a fundamental spatial point process
characteristic that, given the intensity function, determines second order
moments of the point process. Non-parametric estimation of the pair correlation
function is a typical initial step of a statistical analysis of a spatial point
pattern. Kernel estimators are popular but especially for clustered point
patterns suffer from bias for small spatial lags. In this paper we introduce a
new orthogonal series estimator. The new estimator is consistent and
asymptotically normal according to our theoretical and simulation results. Our
simulations further show that the new estimator can outperform the kernel
estimators in particular for Poisson and clustered point processes
