Nowad ays, with the development of internet communication that provides many facilities to the user leads in turn to growing unauthorized access. As a result, intrusion detection system (IDS) becomes necessary to provide a high level of security for huge amount of information transferred in the network to protect them from threats. One of the main challenges for IDS is the high dimensionality of the feature space and how the relevant features to distinguish the normal network traffic from attack network are selected. In this paper, multi-objective evolutionary algorithm with decomposition (MOEA/D) and MOEA/D with the injection of a proposed local search operator are adopted to solve the Multi-objective optimization (MOO) followed by Naï

General medical fields and computer science usually conjugate together to produce impressive results in both fields using applications, programs and algorithms provided by Data mining field. The present research's title contains the term hygiene which may be described as the principle of maintaining cleanliness of the external body. Whilst the environmental hygienic hazards can present themselves in various media shapes e.g. air, water, soil…etc. The influence they can exert on our health is very complex and may be modulated by our genetic makeup, psychological factors and by our perceptions of the risks that they present. Our main concern in this research is not to improve general health, rather than to propose a data mining approach

The perturbation of a satellite high orbit due to the presence of other
gravitational bodies (such as the Sun and the Moon) and SRP from the conservative

Different transition rates of the nuclear preequilibrium states in the exciton model
were numerically calculated in the present work, as well as the state density and matrix
element of the nuclear interaction. The calculations were based on the two-component
version of the exciton model. Some comparisons were made with earlier calculations,
and the results showed a good agreement. The results were explained on the bases of the
effects of the differences in the particle and hole numbers, as well as the type of the
incident particle and its energy. The conclusions indicated that preequilibrium nuclear
reactions induced by protons differ only by small fraction from those induced by
neurons at low exci

The results of this study showed that the correlation between the ionos

Fifty-nine gravity basic stations distributed in southern and eastern Yemen are considered to obtain the regional Bouguer anomaly and isostatic maps of the covered region. The obtained maps show many high amplitude negative anomalies which are related to high elevation area and mass deficiency beneath the continental crust.
Isostatically the study region seems to be overcompensated in high land, while it is nearly complete compensation in low land area. The region requires an upwelling of the mantle material to compensate the mass deficiency in the region. Such process also requires uplift in the earth’s surface, which should have a relation with the tectonic and geomorphologic processes acting in the region such erosion. A comple
