Marine oxygen minimum zones (OMZs) are widespread regions of the ocean that are currently expanding due to global warming. While inhospitable to most metazoans, OMZs are hotspots for microbial mediated biogeochemical cycling of carbon, nitrogen and sulphur, contributing disproportionately to marine nitrogen loss and climate active trace gas production. Our current understanding of microbial com...
multicast routing is one of the most important services in multi radio multi channel (mrmc) wireless mesh networks (wmn). multicast routing performance in wmns could be improved by choosing the best routes and the routes that have minimum interference to reach multicast receivers. in this paper we want to address the multicast routing problem for a given channel assignment in wmns. the channels...
many appealing multicast services such as on-demand tv, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. when multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. designing a good multicast tree to route data packets could enhance the...
in recent years, the issue of energy consumption modeling techniques in the building sector has been widely considered by researchers and managers. researches indicate that energy consumption in residential sector is one of the main parts of the total consumption. moreover, the urban residence is supposed as a significant consumer of energy in every country and therefore a focus for energy cons...
Analogue first, second and high-order all-pass active filters in the current mode, with constant group delay and magnitude responses, are presented in this paper. These filters are based on a modification of the multi-loop feedback canonical structures using signal flow graphs. Implementations by multi-output transconductors, namely classical OTAs and novel CDTAs are given.
Quadruple tank process is a Multi-Input-Multi-Output process exhibiting both minimum phase and non-minimum phase behaviour. In this research, an attempt has been made to mathematically model and design a fuzzy controllerr for the non-minimum phase of Quadruple Tank Process. Both servo and regulatory responses are obtained for the proposed controller.
The bit error rate (BER) performance for ultra-wide band (UWB) indoor communication with the impact of metallic furniture is investigated. The impulse responses of different indoor environments for any transmitter and receiver location are computed by shooting and bouncing ray/image and inverse fast Fourier transform (IFFT) techniques. By using the impulse responses of these multi-path channels...
mobile-ad-hoc-networks (manets) are self-configuring networks of mobile nodes, which communicate through wireless links. the infrastructure of a mobile ad hoc network (manet) has no routers for routing, and all nodes must share the same routing protocol to assist each other when transmitting messages. the main issues in manets include the mobility of the network nodes, the scarcity of computati...
Visualization of object through acoustic waves is generally called as acoustical imaging. This concept contain noise source localization, ultrasonic non-destructive testing, medical ultrasound, underwater sonars, etc. In these conventional imaging techniques, frequency information has not yet utilized effectively, though shape, material and even structure behind the surface reflect on the frequ...
We applied information-theoretic methods to multi-electrode array recordings in the primary visual cortex of cats to quantify the cooperation and temporal structure that arises in the responses to drifting sinusoid gratings. When testing small differences in orientation (<10o), the temporal structure and joint firing can contribute information for discriminating responses. The contributions fro...
