Maastrichtian Aqra limestone Formation at Maukaba and Zardabe localities were sampled for paleomagnetic investigations. 80 oriented limestone drill cores were collected from these localities, which are situated at the northeast part of Iraq. Following stepwise thermal demagnetization procedures, two main magnetic components were determined; a low-temperature component at (20-200)ºC that is regarded as overprint secondary unstable magnetic component with magnetic direction around the present Earth’s field; and medium - high temperature component at (250-600)ºC which is carried by high coercivity magnetic grains. It shows stable magnetic component. IRM reveals that the remanent magnetization in the Aqra limestone Formation is of a depo

Predicting future climate regionally and by space images and landscape studies indicate that the major influences is the increasing of carbon dioxide which attain to more than 350 ppm. The evidences accordingly refer to the increase in the earth temperature which attains to approximately 4 C◦ and 7.2 F◦ causes rapid inversion and changing the climate, so the surface air temperature is 22 C◦ in 1999 will be accordingly more than 26 C◦ in 2090.

In computer vision, visual object tracking is a significant task for monitoring
applications. Tracking of object type is a matching trouble. In object tracking, one
main difficulty is to select features and build models which are convenient for
distinguishing and tracing the target. The suggested system for continuous features
descriptor and matching in video has three steps. Firstly, apply wavelet transform on
image using Haar filter. Secondly interest points were detected from wavelet image
using features from accelerated segment test (FAST) corner detection. Thirdly those
points were descripted using Speeded Up Robust Features (SURF). The algorithm
of Speeded Up Robust Features (SURF) has been employed and impl

Clustering algorithms have recently gained attention in the related literature since
they can help current intrusion detection systems in several aspects. This paper
proposes genetic algorithm (GA) based clustering, serving to distinguish patterns
incoming from network traffic packets into normal and attack. Two GA based
clustering models for solving intrusion detection problem are introduced. The first
model coined as handles numeric features of the network packet, whereas
the second one coined as concerns all features of the network packet.
Moreover, a new mutation operator directed for binary and symbolic features is
proposed. The basic concept of proposed mutation operator depends on the most
frequent value
