Modern power utility systems consist of multiple substations forming a complex energy network. These substations are being automated with globally accepted communication standard IEC 61850. The automation results in efficient operation and enhanced protection of power network with communication system. Implementing the protection schemes modelled with communication configurations with standardized...
Extended network lifetime and load balancing are important requirements for many WSN applications. There are many clustering routing schemes for homogeneous proactive and reactive WSNs but they suffer from the problem of uneven load distribution and back transmission. This paper presents an energy efficient load balanced clustering scheme with away cluster head (ACH) scheme and free association mechanism...
It is common awareness that occasionally wild animals forage into human habitations in search of food and humans forage into the forest for livelihood and poaching. This trespassing into each other's territory often leads to human-animal conflict. Further, the human presence and actions in the forest would lead to the destruction of the forest and degradation of the forest habitat for the wild animals...
Recommender systems solve the problem of information overload, by helping to find the most suitable items from a large set. Evaluating recommender system and made recommendations are equally important in an efficient recommender system. Though quality assessment of recommender system can be done using various measures, accuracy is the most important one. Sometimes accuracy may lead to a lack of user...
Day by day reliability is more concern with electricity issues and transformer itself is most important equipment in supplying electricity. Discrimination between inrush current, CT saturation, external fault and internal fault is required for necessary operation of power transformer. Also the mal-operation of transformer protective scheme during external fault and inrush condition should be minimized...
In recent years, significant increase in the demand of energy due to urbanization and industrial growth is recorded. Various research efforts have been carried out for the optimal design of modern power distribution systems. To meet the load growth in optimal manner and overcome pseudo dynamic behaviour of different network parameters, the distribution system capacity expansion is needed. Distribution...
In this paper, we have studied one of the most recommended configurations for exciting Surface Plasmon Polariton (SPP), the Kretschmann-Raether structure, along with a less studied but very promising metal for inducing the resonance between plasmons and electromagnetic wave, Gold. We have presented several noteworthy characteristics of this particular material that can be taken into consideration...
Renewable sources of energy is now playing a very important role in the electrical power supply. In near future significant portion of total power generated will be obtained from renewable energy sources like solar, wind etc. In thermal power plant conventional frequency control technique is done using Automated Load Frequency Control model using governor and assisted supervisory control. This will...
This paper presents ant lion optimization method for multi-objective optimum generation scheduling problem (MOGS) in various test power systems. Ant Lion Optimization (ALO) is a novel meta-heuristic motivated by hunting mechanism of ant lions in nature. Diverse emission gases considered for the case studies are SOx, NOx and COx. The proposed technique is applied on different test systems for solving...
As the technology progressing, WSN (Wireless sensor network) become a suitable choice for data gathering and monitoring applications. Power consumption is an important consideration for the design of sensor network. As the WSN is powered by small batteries and deployed in remote location where it is not possible to charge and change these batteries, so it is very important to reduce the energy consumption,...
In this paper a hybrid shape fractal microstrip patch antenna is presented which use FR-4 substrate having thickness of 2.4mm. Coaxial probe feed is used in this antenna. Fractal geometry is used for multiband behavior. In order to achieve wideband characteristics, defected ground structure technique (DGS) is applied. The antenna resonates at 5.2GHz, 5.6GHz, 6.3GHz and 7.6GHz with bandwidth 705MHz,...
Measurement of precise synchronized voltage and current values are paramount in power system. Through synchronisation it is possible to locate phasors, taken at different locations, on same phasor diagram. It is helpful in analyzing, monitoring and controlling the power systems during dynamic and transient state. PMU (Phasor Measurement Unit) is a gold standard device, synchronized with highly accurate...
Viva assessments are an important part of the curriculum in all the professional and academic courses. Since ages, the processes has been handled manually and hence has been prone to errors and mal practises. Considering the wide usage of the procedure in determining the performance of the individuals and the fuzzy nature of the evaluation process, we have presented an algorithm to calculate the viva...
The present work reports the fabrication and optical characterization of n-TiO2 thin film prepared by sol-gel method. Sol-gel solution of TiO2 was prepared using titanium isopropoxide and hydrochloric acid as a precursor and stabilizer, respectively. As-deposited, TiO2 thin film on p-Si and glass substrates have the thickness of ∼120 nm. The surface morphology and crystallinity of the as-deposited...
In the current technology world, data transmission of various multimedia like sensitive images, video, text is very important and security is major concern in the fields of medical, commercial and military fields. Security is very important, as illegal users may hack the sensitive data. Currently, many techniques are available for secure transmission of data through internet. Some examples of such...
As the technology of memory on Systems-on-Chip (SoC) is shrinking, the compact devices and embedded systems are emerging, so the low power consumption is very essential for the VLSI system design. Static Random Access Memory (SRAM) contains more than 70% area of the SoC. A standard 6T SRAM cell has two bitlines for read and write operation thus it consumes more power. There are many techniques for...
The Single Fluid Heat Transfer System (SFHTS) uses single fluid to heat and cool the mass or the reactants. It is widely used in the pharmaceutical industry. Traditionally, Proportional Integral Derivative Controller or Proportional Integral controller is used to control the operation of SFHTS. In this research work, investigation was carried out to estimate the dynamics of the SFHTS which confirmed...
