The five major rainforest regions (Asia, Africa, Madagascar, Neotropics, and New Guinea) are distinct ecological and biogeographical entities, each with its own levels of threat from various human activities. The purpose of this chapter is to review these threats, and then to evaluate the conservation strategies being used to deal with them. Across the tropics, commercial logging is increasingl...

The main objective of the research presented in this paper is to enhance driver-passengers comfort a vehicle that turn leads better safety and stability. focus was put on studying interior vibration noise contributions originated from tire-road engine-transmission subsystems, due their significant impact dynamic performance vehicle. measurements were recorded at driver’s head position driver le...

This paper describes the experience and the results of using the VigilAgent agent methodology to develop surveillance systems. This work is based on the suitability of agent characteristics for developing surveillance systems. It is usual to develop them following an ad-hoc approach instead of using a methodology to guide stakeholders in achieving quality standards expected from commercial soft...

Department of Chemistry, Avinashilingam Deemed University for Women, Coimbatore641 043 ABSTRACT Lipophilicity which plays an important role in research into the structure-activity relationship of drug action has been theoretically predicted for few chromen-2-ones and chromen-2-thiones using commercial software HyperChem 7.0 and an internet computational software ALOGPS 2.1. In the compounds ana...

The use of commercial echosounders for scientific and industrial purposes is steadily increasing. In addition to traditional navigational and fisheries uses, commercial sonars are used extensively for oceanographic research, benthic habitat mapping, geophysical exploration, and ecosystem studies. Little is known about the effects of these acoustic sources on marine animals, though several studi...

This paper focuses on the requirements for face images to be used in Machine Readable Travel Documents, defined in the ISO/IEC 19794-5 standard. In particular an evaluation framework is proposed for testing software able to automatically verify the compliance of an image to the standard. The results obtained for thee commercial software are reported and compared.

this study aimed to develop techniques for purification of cyanotoxins dissolved in water -particularly those produced by microcystis aeruginosa species - using natural clay, chemically modifiednatural clay, commercial clay and ion exchange and adsorbent resins. except for natural clay, chemical pretreatment was required to increase the adsorption capacity of the treatment materials. all the cl...
