The aim of this study was to assess selected properties coatings incorporating nanocellulose, with the potential being applied as a surface modification for cellulosic and lignocellulosic materials, particularly applications within biodegradable packaging. Cellulose nanocrystal (CNC) cellulose nanofibril (CNF) were produced on both sides pure samples in form filter paper Mayer bar. Selected org...

in this paper, we deal with the problem of adaptive coherent signal detection in gaussian interference (clutter plus noise) for surveillance pulse radars. some of the adaptive radar detectors exploit the ar model for clutter. most of these detectors have been obtained using the glr test. this test relies on the maximum likelihood estimation whose accuracy depends on the number of data. whereas,...

Since the report by Goetz (1947) on the nature and use of membrane filters in Germany, a number of papers have appeared in this country on membrane filter technics for the bacteriological analysis of water. Interest in the use of these membranes was particularly stimulated in 1951 following the publication of papers by Clark et al. (1951) and Goetz and Tsuneishi (1951). These investigators desc...

In this paper, we introduce the concepts of right, left and product stabilizers on hoops and study some properties and the relation between them.  And we try to find that how they can be equal and investigate that under what condition they can be filter, implicative filter, fantastic and positive implicative filter. Also, we prove that  right and product stabilizers are filters and if they are ...

In the present study, dormancy and germination requirements were investigated in seeds of Citrullus colocynthis (L.). Seeds were subjected to 10 pretreatments in the present study.  These pretreatments included hot water (100° C) followed by the seeds placed between double layered filter paper moistened with 5 ml of distilled water and kept at 28 - 30 °C, sulphuric acid (98% v/v), for 30 min fo...

Control of a class of uncertain nonlinear systems, which estimates unavailable state variables, is considered. A new approach for robust tracking control problem of satellite for large rotational maneuvers is presented in this paper. The features of this approach include a strong algorithm to estimate attitude, based on discrete extended Kalman filter combined with a continuous extended Kalman ...

in this paper, behavior of teleoperation systems with modeling error and delay time error in smith predictor is discussed. in teleoperation systems, modeling error is inevitable. this paper discusses stability of teleoperation systems with modeling error. first, error of delay time in teleoperation systems by using of internet as communication channel is considered and the performance of smith ...
