Objective assessment of the image quality is of keen importance in numerous image processing applications. Various objective quality assessment indexes have been developed for this purpose, of which Peak signal-to-noise ratio (PSNR) is one of the simplest and commonly used. However, it sometimes fails to give result similar to as perceived by the Human Visual System (HVS). This paper presents a modified...
This paper presents a new full-reference image quality metric for objective assessment in spatial domain. This metric empirically combines some standard image metrics for assessment of complete visual distortion. The proposed quality metric (Q) is formulated by modeling an image distortion as a combined effect of structural distortion, contrast distortion and edge distortion, which may occur on account...
A polygonal shaped printed antenna operating in the Federal Communication Commission (FCC) regulated ultra wideband (UWB) band has been proposed. The design consists of a combination of basic polygonal structure and truncation in the ground plane operable at FCC defined UWB band. The key contribution of this article is a defective microstrip structure (DMS) that creates the notch at the desired WLAN...
CGID (Commercial Grade Item Dedication) is Equipment qualification method, assured quality activity for validation and verification results by test, inspection and analysis, using approved procedures, test plan and test methods for safety class, purchased CGIs. And utility and dedicating entity should be required a 3-parts positions on qualified inspector and engineer. Qualification results shall...
In this paper, a Genetic Algorithm (GA) based fuzzy goal programming (FGP) technique to multiobjective optimal planning of electric power generation and dispatch problem in power system operation and planning phases is presented. In the proposed approach, fuel cost, environmental emission and voltage deviation objectives of optimal power flow calculation are fuzzily described. In the solution process,...
The work presents how a dual formula generated seed based cryptographic technique (de)ciphers with stochastic initialization of the parameters constituting the seed. In the model formulation of the technique, two distinct formulas are used for creating two arrays of number, followed by XOR and XNOR operations performed on those two arrays in order to produce the crypt arithmetic seed. In the process...
In case of wireless networks with infrastructure there is a base station which is reachable through all mobile nodes. Ad-hoc network defers in this point where destination nodes might be unreachable from source nodes. The Mobile Ad-Hoc Network are prone to packet loss and route congestion due to their dynamic nature. The lack of centralized infrastructure adds up to these problems. In this respect...
A fast and accurate CAD model based on cavity model analysis is proposed in this paper for computing the input impedance of circular patch antenna operated in between 0.8 to 1.33 GHz. The proposed model is valid for vary large to very small value patch diameter with any feed position. The computed values of circular patch having different diameter with different feed locations are compared with different...
The force that drives towards small satellites is mainly cost and fast realization compared to large satellites. The low-cost space system is built by maximizing the use of existing component and off the shelf technologies/standards and thus minimizing the development effort. Small satellites missions are highly demanded for the research, military, agricultural and scientific missions. In small satellite...
Cognitive radio is a revolutionary evolution of future wireless communication to utilize the unused part of the spectrum, which is actually assigned to licensed services only. An NC_OFDM based cognitive radio has the capability to nullify individual sub carriers to avoid interference with the licensed user. So, that there could be a large number of zero valued inputs/outputs compare to non-zero terms...
A nonlinear nuclear reactor model is linearized at different initial powers for the purpose of controlling the reactor in load following mode. A new fractional order (FO) fuzzy proportional integral derivative (PID) controller is tuned next using Genetic Algorithm (GA) to control the reactor at different operating conditions. The effectiveness of using the fuzzy FOPID controller over conventional...
A low cost, Cell Phone based system design has been proposed in this paper, which would automatically inform the nearest Police Radio Flying Squad or Traffic Dept. vehicles from a vehicle affected in an accident without the need of any human intervention. The collision detector inside the vehicle would send an update to the Police Control Room Server which in turn would immediately send a ‘SMSOrder’...
Fractional order models in One Non-integer Order Plus Time Delay (NIOPTD-I) template have been used for time domain online and offline system identification. A newly proposed Nyquist based model reduction technique has been used for reduced parameter modeling of the identified models. The comparative accuracies of the test plants in the online and offline identification and reduced parameter modeling...
The main reasons hindering the wide spread deployment of passive RFID tags are high cost and limited range. The present work focuses on developing a sub-cent RFID capable of operating from a reasonable distance, though with some compromise on the information content. Since there are ample applications of read-only RFID with limited information content, the present technology is expected to fill a...
Designing an efficient micro-mobility scheme for network mobility (NEMO) is an important issue. The Micro-NEMO is a well known protocol for micro mobility in NEMO. It has significantly lower signaling overhead and handoff latency. But, it suffers from single point failure problem. In this paper, we propose micro-NEMO++, an extension of micro-NEMO protocol, to eliminate the single point failure problem...
MANETs are networks capable of communicating in a set of small, low cost, low power sensing devices. A wireless sensor networks is totally based on the limiting factor i.e. energy consumption. A wireless sensor network consists of large number of sensor nodes distributed or scattered in particular network region. MANETs consist of node that is highly mobile, so in particular the range of the nodes...
A single feed microstrip patch antenna is designed which consists of 3 concentric ring micro strip patches with a circular patch at their center on signal plane and a “T” shaped slot cut at ground plane. This proposed antenna is designed on PTFE substrate. It provides multiple resonanting frequencies at 1.06 GHz, 1.49 GHz, 2.11 GHz, and 3.01 GHz respectively with •10 db return loss bandwidth and aproximately...
