An efficient method to improve the Logistic map: Design and implementation

Abstract: In this paper, we have designed and proposed a new improved Logistic map (ILM) which enhances the performance of the standard Logistic map (SLM) in terms of higher Lyapunov exponent and steady chaotic behavior. In standard map, the control parameter is limited and should be close to 4 to exhibit chaos. Additionally, in some specific region called as islands of stability, the system behaves non-chaotic. However, for the improved one, the control parameter is not limited to a finite value for the system to be in chaos state and provides chaotic behavior all the time. Firstly, we have designed a new chaotic map and modeled it by using Xilinx block sets in Matlab/Simulink environment. Then, we have realized the ILM through hardware-co simulation on FPGA (Field programmable gate array) for practical applications.

A computer vision system for classification of some Euphorbia (Euphorbiaceae) seeds based on local binary patterns

Abstract: In this study, a computer vision system was proposed for the seed images classification. The classification process was performed using uniform local binary patterns obtained from digital seed images. In this study, 240 (120 training and 120 test) images of the seed were used. First, the average uniform histograms of each type of seed (seed type classes) was obtained for the training set. Then the uniform LBP histogram of each seed in the test set were produced and compared with histograms of classes by using nearest neighbor. The Euclidean distance, sum square error, histogram intersection and Chi-square statistics were used to calculate the distance between seed samples. 95.83% of seed images has been diagnosed properly with the proposed. As a result, the surface shape of the seeds include important information patterns to determine the taxonomic relationships,it is is expected that the computer vision systems provide significant advantages to identify the type of seed.

Antioxidant and antimicrobial responses associated with in vitro salt stress of in vitro and in vivo grown Pistacia khinjuk stocks

Abstract: P. khinjuk Stocks, known as Bittim or Buttum in Turkey, is a member of the Anacardiaceae family. The essential oil of khinjuk pistachio has been used to treat various illnesses because of their anti-inflammatory, anticancer, antipyretic, antibacterial, anthelmintic, antiviral effects in various folk medicines. At the same time, fruits of khinjuk pistachio are used as edible wild fruits. In this study, it was aimed to determine and compare the antibacterial, antioxidant activities and total phenolic and flavonoid amounts of different parts (root, stem and leaf explants) of in vivo (grown naturally) and in vitro derived khinjuk pistachio plants under salt (NaCl) stress. Ethanol extracted explants were used for performing biological and chemical parameters. According to the results, generally, in vivo samples shows higher antioxidant and antimicrobial activity besides the higher number of phenolic compounds than their counterparts in vitro. We have also determined that the biological activity of in vitro salt elicited explants was higher than in vitro control explants. Generally, both female and male in vivo samples have higher antioxidants (DPPH, ABTS, CUPRAC) and antimicrobial activities than in vitro samples. The various plant parts (root, stem, leaf) belonging to both in vivo and in vitro samples have different biological activity level. In terms of antimicrobial activity, female plant extracts are more active than all other tested extracts. As a result, although increased salinity values significantly reduced antimicrobial activity, it is determined that 100 mM NaCl applications to in vitro leaf extracts exhibited moderate antimicrobial activity against S. aureus and C. albicans.
