Bioelectrochemical system (BES) is a novel, self-sustaining metal removal technology functioning on the utilization of chemical energy of organic matter with the help of microorganisms. Experimental trials of two chambered BES reactor were conducted with varying substrate concentration using sodium acetate (500 mg/L to 2000 mg/L COD) and different initial chromium concentration (Cri) (10–100 mg/L)...
One of the major disorders affecting the human brain is epilepsy and it impairs the daily lives of the patients. Epilepsy is caused by sudden and random incidence of seizures. One of the most powerful tool for diagnosing various neurological disorders including epilepsy is Electroencephalogram (EEG). Recognizing the people who have a disorder of the brain by means of inspection of EEG signals visually...
A new design method for PID controller using user-specified gain margin and phase margin for delayed systems has been proposed. The proposed PID controller is particularly useful in auto-tuning. The controller parameters are calculated using several approximations and elimination processes. The robustness of the proposed controller is verified by different simulation examples.
This paper develops a model for Wells turbine using Xilinx system generator (XSG)toolbox of Matlab. The Wells turbine is very popular in oscillating water column (OWC) wave energy converters. Mostly, the turbine behavior is emulated in a controlled DC or AC motor coupled with a generator. Therefore, it is required to model the OWC and Wells turbine in real time software like XSG. It generates the...
Influence of nanoparticles on failure load of adhesive bonded single lap joint was investigated experimentally and by finite element method (FEM). Aluminum alloy and epoxy were used as adherend and adhesive respectively. Alumina nanoparticles having diameter in the range of 23–47 nm were used to reinforce epoxy. Nanocomposite adhesives having 0.5, 1.0, 1.5 and 2.0 wt.% of alumina nanoparticles were...
Cam follower mechanisms are used for obtaining complex motion outputs at follower end with different profile curve inputs at cam end. The kinematic behaviour of follower establishes basic suitability of cam for a given application and it is decided by the cam profile curves, which is main input of cam follower system. In this paper synthetic curves, that are generated parametrically through a set...
Refrigerator glass shelves are assembled with plastic frame and the final assembly is slid into the grooves of the refrigerators inside the plastic liner. Refrigerator manufacturers across Northern India outsource the manufacturing and assembling of refrigerator shelves to small scale industries who after manufacturing the polypropylene plastic frame from injection molding and procuring the tempered...
Transformation of occurred rainfall into runoff generated within a catchment is a complex natural phenomenon that passes through various inter-related processes and influenced by many topographic, geographic, geologic and sociologic factors. To develop a model that can reliably imbibe the complex Rainfall-Runoff interaction, two different approaches namely, conventional regression and Artificial Neural...
Existing facial expression recognition (FER) algorithms aim to extract discriminative features from a face. These discriminative features can be extracted only from the informative regions of a face. In this view, several face models are proposed which are mainly intended to extract geometrical features from a face, and hence these models may not be suitable for extract discriminative texture features...
In present paper, a non-cascading converter is presented. It is very useful as far as overall efficiency of the converter is concerned. Here the input power is transferred to the load through a non-cascading scheme employed on the secondary side of an isolation transformer. It requires the intermediate capacitor of lower ratings and at the same time improves the power transfer capability of the converter...
This research relates to the estimation and analysis of solar irradiance at Indore located in the state of Madhya Pradesh central region of India having longitude 77° 50' east and latitude 22° 44' north. The incident solar irradiance energy which depends the geographical region and weather conditions. The component of irradiance depends upon variation in the global and diffuse solar radiation. In...
A new method of model order reduction technique for interval system is proposed here. The reduced order denominator coefficients are determined by combined benefits of reciprocal transformation, principal pseudo break frequency and a new method of eigen spectrum analysis. Then the reduced order numerator coefficients are obtained using polynomial coefficient matching method. Optimization method can...
This paper presents the analytical potential modeling of Double Gate (DG) Tunnel Field Effect Transistor (TFET) at 50 nm channel length. In this model approach the channel potential is sum of a long channel potential and a short channel perturbation along with the whole structure rather than just the Si/SiO2 interface or the channel centre. For the validation of our analytical modeling approach we...
In this work, a theoretical neuronal model incorporating the aggregate effect of distributed delay, in terms of excitatory and inhibitory potentials, is proposed. Monte Carlo simulation based study have been done for the proposed model. A comparative study for spiking activities of proposed model with leaky integrate-and-fire (LIF) model, neuronal model with weak delay and neuronal model with strong...
Computational modelling with the use of intelligence techniques for computing the agricultural output by providing minimum input data to lessen the time through cutting down the multi locational field trials and also the labours and other inputs is getting momentum. Development of locally suitable integrated farming systems (IFS) is the utmost need of the day, particularly in India where about 95%...
In WSN (Wireless Sensor Network) every sensor node sensed the data and transmits it to the CH (Cluster head) or BS (Base Station). Sensors are randomly deployed in unreachable areas, where battery replacement or battery charge is not possible. For this reason, Energy conservation is the important design goal while developing a routing and distributed protocol to increase the lifetime of WSN. In this...
This paper presents the stability investigation of Internal Model Control (IMC) based control design of doubly-fed induction generator (DFIG) in Stator-Voltage-oriented (SVO) synchronous reference frame. The state-space model of DFIG including inner current closed loop dynamics with different feedforward compensation schemes is developed. The inner current loop dynamics is usually ignored when SVO...
In current scenario, the need of surveillance applications, technological improvements, and the numbers of active real-time surveillance systems are increasing continuously throughout the world. In this research work, we have presented a background subtraction based scheme for moving object detection in video frames. The proposed scheme has a strong potential for applications in consumer electronics...
In this paper we explore the performance of multilingual speaker recognition systems developed on the IITKGP-MLILSC speech corpus. Closed-set speaker identification and speaker verification experiments are individually conducted on 13 widely spoken Indian languages. In particular, we focus on the effect of language mismatch in the speaker recognition performance of individual languages and all languages...
In this paper, we propose a mixed preemptive and non-preemptive resume priority (PRP/NPRP) M/G/1 queueing model for the modeling of the traffic in Cognitive Radio (CR) Networks with prioritized transmissions. A traffic-adaptive spectrum handoff scheme is then developed based on the proposed queueing model for delay sensitive applications. This spectrum handoff scheme reduces the delivery time of the...
