In recent years, wireless ad hoc sensor network becomes popular both in civil and military jobs. However, security is one of the significant challenges for sensor network because of their deployment in open and unprotected environment. As cryptographic mechanism is not enough to protect sensor network from external attacks, intrusion detection system needs to be introduced. Though intrusion pre...

The Paraíba is an Au-Cu-Mo deposit located in the southern part of Amazon Craton, Alta Floresta Mineral Province, Mato Grosso State, Brazil. It composed Au-Cu-bearing quartz veins and Cu-Mo-rich hydrothermal breccias stockworks, both associated with several alteration zones. integration spectral (reflectance imaging spectroscopy) conventional techniques (core logging, petrography, mineral chemi...

In this paper, we propose an approach for automatic generation of novel intrusion signatures. This approach can be used in the signature-based Network Intrusion Detection Systems (NIDSs) and for the automation of the process of intrusion detection in these systems. In the proposed approach, first, by using several one-class classifiers, the profile of the normal network traffic is established. ...

INTRODUCTION A variety of mantle-derived igneous rocks comprise the primary sources of diamond, with the principal hosts being kimberlite and lamproite. Primary diamonds or graphite pseudomorphs after diamond are also known to occur in some lamprophyres (Jaques, Kerr et al., 1989), alkali basalts and alpine type peridotites (Kaminskii, 1984). Significant quantities of diamond have not yet been ...

Water quality conditions have been assessed in the Río Vélez coastal aquifer (Andalusia, South Spain: an area of important agricultural and touristic development). This shallow fluvio-deltaic aquifer consists of coarse detrital deposits, of Quaternary age, that extend over about 20 km, being subdivided in two sectors –fluvial and deltaicby a substratum elevation. The deltaic sector is highly vu...

Purpose: To review drusen and sub retinal drusenoid deposits in age related macular degeneration as regards their pathogenesis, morphology, differentiation and their importance as regards the visual prognosis of age related macular degeneration (AMD). Results: Each type of drusen or drusenoid deposits has a different visual prognosis, and the differentiation of them using multimodal imaging tes...

As mobile ad hoc networks (MANET) have different characteristics from wired networks and even from standard wireless networks, there are new challenges related to security issues that need to be addressed. Due to its unique features such as open nature, lack of infrastructure and central management, node mobility and change of dynamic topology, prevention methods from attacks on them are not en...

This paper describes a set of metrics that will help administrators of distributed, real-time (clustered) computer facilities to select the best intrusion detection system for their facilities. The metrics herein are the subset of our general metric set that particularly impact real-time and distributed processing issues. We discuss related works in this field, the role of intrusion detection i...

introduction the study area is located in central part of the khaf- kashmar-bardeskan belt which is volcano-plutonic belt at the north of the dorouneh fault in the north of lut block. the north of the lut block is affected by tectonic rotation and subduction processes which occur in the east of iran (tirrul et al., 1983). the magmatism of lut block begins in jurassic and continues in tertiary (...
