Quarantine region scheme to mitigate spam attacks in wireless sensor networks
The Quarantine Region Scheme (QRS) is introduced to defend against spam attacks in wireless sensor networks where malicious antinodes frequently generate dummy spam messages to be relayed toward the sink. The aim of the ...
Querying sensor networks by using dynamic task sets
(Elsevier B.V, 2006-05-15)
A data querying scheme is introduced for sensor networks where queries formed for each sensing task are sent to task sets. The sensor field is partitioned into subregions by using quadtree based addressing, and then a given ...
A parallel implementation: Real space Green's function technique
(Sage Publications, 2007-04)
We develop an MPI-based parallel algorithm to implement the real space Green's function technique for calculating the vibrational density of states corresponding to a solid. The Hamiltonian describing the interactions ...
On the identification of microstretch elastic moduli of materials by using vibration data of plates
(PERGAMON-ELSEVIER SCIENCE LTD, 2008-06)
In the present work, the vibration problems of rectangular plates modeled by Eringen's microstretch theory are investigated for the identification of the upper bounds of the microstretch moduli of the plate material. The ...
Relocating sensor nodes to maximize cumulative connected coverage in wireless sensor networks
(Molecular Diversity Preservation Int, 2008-04)
In order to extend the availability of the wireless sensor network and to extract maximum possible information from the surveillance area, proper usage of the power capacity of the sensor nodes is important. Our work ...
The composition of acids in bitumen and in products from saponification of kerogen: Investigation of their role as connecting kerogen and mineral matrix
(ELSEVIER SCIENCE BV, 2008-11-03)
In order to obtain more information and to understand the nature of relation between organic and mineral matter in oil shales, the compositions of soluble bitumen fractions obtained by extraction from Bulgarian oil shales ...
Numerical calculations of relativistic electron drift loss effect
(AMER GEOPHYSICAL UNION, 2008-09-09)
It has been suggested that drift loss to the magnetopause can be one of the major loss mechanisms contributing to relativistic electron flux dropouts. In this study, we examine details of relativistic electrons' drift ...
Foreign direct investment in Turkey: Historical constraints and the AKP success story
(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD., 2008-01)
Economic development on an unambiguously national basis was one of the foundational principles of republican Turkey. Indeed, until very recently, foreign direct investment (FDI) was scant and had a marginal presence in the ...
Characterization of Bulgarian oil shale kerogen revealed by oxidative degradation
(ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2009)
A 13-step alkaline permanganate degradation of Bulgarian oil shale kerogen concentrate at ambient temperature was carried out. A high yield of oxidation products (90.1%) and a low yield of gaseous products (2.79%) were ...
