In this paper, we consider the problem of emergency response resource storage locations and capacities. Resources are important for disaster relief operations in coping with natural and manmade emergencies. In order to enhance the ability of response to disasters, different levels of reserve system need to be set up for holding relief resources. These emergency storages may have different capac...

A wide variety of nanomaterials can be found naturally occurring in the environment, although finding and characterizing these materials remains a challenge due to their size. Recent studies in the field have shown that natural nanomaterials are common in many geochemical systems. In this issue of ACS Nano, Hutchison and co-workers make us realize that manmade nanomaterials can often be practic...

In this work we propose a mathematical model, based in a modified version of the Lotka-Volterra prey-predator equations, to predict the increasing in CO2 atmospheric concentration. We consider how the photosynthesis rate has changed with the increase of CO2 and how this affects plant reproduction and CO2 absorptions rates. Total CO2 emissions (natural and manmade) and biomass numerical paramete...

This paper presents an alternative procedure for the prediction of propagation path loss in urban environments. It is based on Neural Network (NN) algorithms and uses the detailed environment profile instead of the mean values of its structural parameters. The general performance of the NN shows its effectiveness to yield results with satisfactory accuracy in short time. The received results ar...

The main purpose of Wireless Sensor Networks(WSN) is to aggregate data from natural and manmade resources. In this process various sensor nodes senses data and disseminates them to the data aggregation centre termed as Sink node, which acts as a bridge between real time and digital world. This data dissemination process must be proper without node failures, data loss, and redundant occurrence o...

We present a real-time vision navigation and ranging method (VINAR) for the purpose of Simultaneous Localization and Mapping (SLAM) using monocular vision. Our navigation strategy assumes a GPS denied unknown environment, whose indoor architecture is represented via corner based feature points obtained through a monocular camera. We experiment on a case study mission of vision based SLAM throug...

Many useful manmade systems in this world are extremely complex; a typical example is a large infrastructure. No design team ever invents these artefacts because they are too complex. The artefacts are made by combining existing elements (legacy) and by building new subsystems without explicit and comprehensive up-front coordination. To a large extent, these complex systems emerge and evolve. E...

Seamless integration of biomolecules with manmade materials will most likely rely on molecular recognition and specific binding. In the following we show that combinatorial antibody libraries, based on the vast repertoire of the human immune system, can be harnessed to generate such binders. As a demonstration, we isolate antibody fragments that discriminate and bind selectively GaAs (111A) fac...

Background Nucleoside reverse transcriptase inhibitors (NRTIs) were the first drugs introduced for treatment of human immunodeficiency virus-1 (HIV-1) infection. These NRTIs may be cyclic or acyclic analogs of natural nucleosides. Both these analogs interact at active site on HIV-RT and compete with indigenous nucleosides/ nucleotides, and thus, divert enzyme activity in manmade direction. All ...

A new method for finding geometric structures in digital images is proposed. An adaptive algorithm of straight line segments extraction is developed for manmade objects description in digital images. It uses an adjustment of oriented filter angle for precise extraction of line corresponding to real edge. Perceptual grouping approach is applied to these segments to obtain simple and complex stru...
