TL;DR: This research issue is solved using image processing techniques and Gabor wavelet is used for key of feature extraction method and texture patter classification accuracy is improved and false positive rate is decreased.
Abstract: The malicious data’s are grouped into various types of viruses such as Trojan, Trojan downloader and so on. The cyber security issues are increasing day to day. It is a challenging task for the network security and antivirus designers. Trojan malware family has been used to detect the newly arrived malicious data to a known group. It is a well popular research problem to detect and classify the Trojan viruses. This research issue is solved using image processing techniques. To identify the texture patterns of malware images is tedious task, because of the similarities present in the various malware families. In this proposed algorithm Gabor wavelet is used for key of feature extraction method. The dataset Malimng consists of the 25 malware variant families for each class max 300–1000 samples are there. The experimental results are analyzed compared with two classifications such as KNN and SVM. The texture patter classification accuracy is improved and false positive rate is decreased. The KNN gives accuracy 89.11% and SVM gives 75.11%.

TL;DR: In this paper, the authors studied the capture of planetesimals in Trojan-type orbits by a growing proto-planet and found an interesting mechanism which could explain the observed high inclination Trojans.
Abstract: We have studied the capture of planetesimals in Trojan-type orbits by a growing proto-planet. The change of the gravity field due to the mass growth causes a significant fraction of planetesimals orbiting nearby to be trapped as Trojans of the proto-planet. After a planetesimal is captured on a Trojan-type orbit, the libration amplitude of its critical argument is consis- tently reduced by the further mass growth of the proto-planet. The dynamical mechanism is discussed and the characteristics of the Trojan population captured by Jupiter during its growth are analysed. We find an interesting mechanism which could explain the observed high inclination Trojans. The synergy of a Kozai sec- ular resonance with the growth of Jupiter's mass generates high inclination Trojans from low inclination-high eccentricity plan- etesimals orbiting near the growing proto-planet. The libration amplitudes of the model Trojans trapped by the mass-growth of Jupiter are higher compared to those of the observed Trojans. A possible mechanism that decreases the libration amplitudes of the model population is collisional evo- lution. We also show that the simultaneous formation of Jupiter and Saturn strongly inhibits the capture of planetesimals as Saturn Trojans. The interference of the 1:1 resonance with a secular resonance and, in some cases, also with the 5:2 resonance with Jupiter (Innanen and Mikkola, 1989), generates instability and causes the ejection of most Saturn Trojans out of resonance before the end of Saturn's mass growth.

TL;DR: In the long section of anapaests with which they make their entry, the old men of Argos methodically deliver three essential messages to the audience:40−71.72−82.83−103.
Abstract: In the long section of anapaests with which they make their entry, the old men of Argos methodically deliver three essential messages to the audience:40–71. It is the tenth year of the Trojan War.72–82. We are men who were too old to go and fight in it.83–103. Some new situation seems to be indicated by the fact that Clytemnestra is organizing sacrifices throughout the town.

TL;DR: In this article, it was suggested that a relatively elongated shape of the nucleus of the main belt asteroids may explain the observed rotationally splitting of the nuclei of the Trojan asteroids.
