India has ratified the Paris agreement and also committed in its Intended Nationally Determined Contributions(INDC) that it will reduce it's emissions intensity of its Gross Domestic Product by 33 to 35 percent by 2030 from its 2005 level. Indian Railways(IR) played a lead role in the Conference of Parties held in Paris on climate change in December 2015. As a part of Railways' INDC, IR has committed...
With the advancements in electronics and communication, the electronic devices are being interconnected to create a controlled environment. The number of devices that are being connected to the Internet is booming day-by-day. However, the existing protocols are verbose and overburden the embedded devices having constrained resources in terms of memory, computational power, battery etc. As a relief,...
The resource allocation problem is investigated for an Uplink OFDMA based system. The subcarrier and power allocation issue was formulated as an optimization problem with the objective of maximizing the overall system rate, and maintaining a minimum rate for every user, so that fairness is addressed. Two level dual decomposition algorithm was adopted to derive the optimal power and subcarrier, while...
Proposed coplanar waveguide (CPW) fed meta-material antenna is also one of them to invoke the multiband applications in the frequency range of 5.4–5.8GHz. Meta-materials are capable to manipulate EM waves by blocking, absorbing, enhancing, and bending waves and also radiate more energy. The proposed antenna having the hairpin structure is designed with FR4 substrate having permittivity of 4.4 and...
A worm is a standalone program, which is self-replicating malware that distributes itself to other computers and networks. An Internet worm can spread across the network and infect millions of computers in very little time. Damages caused by such attacks are considered very high. Worms affect the network packet and its performance. In this paper, different methods are analyzed to detect Internet worms...
With increasing use of power electronics, the amount of harmonics and other power quality problems are increasing in the system. Because of this power quality has been an important topic in the area of research. There are a number of reliability and economic issues with respect to electronic equipment. In such a scenario it is important to study the causes, effects and mitigation technologies for...
E-payment systems by their nature are complex. Thus, with lack of well-designed formal models to provide a suitable method for their modelling and monitoring many challenging tasks will remain unsolvable. The present work aims at designing and implementing an e-Payment Protocols Formalism, PPF, to allow properties examination and verification for e-payment protocols. The proposed formalism was built...
Channel allocation possibilities of femtocells are analyzed in this work. Femtocells have gained importance in the recent times because of their scope to offer better frequency reuse in cellular systems. They are poised to play their prominent role in future 5G systems also. While allocating the operating frequencies to femtocells, care needs to be taken to avoid interference with neighboring femtocells...
Floating-point arithmetic plays major role in computer systems. Many of the digital signal processing applications use floating-point algorithms for execution of the floating-point computations and every operating system is answerable practically for floating-point special cases like underflow and overflow. The single precision floating point arithmetic operations are multiplication, division, addition...
Pulse oximeters use photoplethysmographic (PPG) signals for measurement of oxygen saturation in arterial blood. They measure volumetric changes in the blood flowing through the body, usually extremities such as a finger or an ear lobe. The peripheral pulse signal obtained by transmitted light through the illuminated body extremity, gets modulated by heart synchronous pulse, respiratory activity and...
Segmentation divides an image into different regions with each pixels having similar characteristics. Each of the segmented regions should strongly relate to objects in the image or features of interest for segmentation to be meaningful in image processing. Many methods for image segmentation depends on partitioning of an image into several similar regions. The superpixels generation method have gained...
This paper describes a method for implementing a digital Infinite Impulse Response (IIR) filters using different registered adders and shift method to improve occupied area and delay. Canonical Signed Digit (CSD) representation for defined filter coefficients has been extensively used to reduce the number of adders. The method using different adders is effectively applied to a four-order IIR filter...
Nuclear fusion is the upcoming trend to develop high power and meet the energy requirements in the world. International Thermonuclear Experimental Reactor (ITER) is a megaproject to develop a reactor producing high amount of power through nuclear fusion. For the fusion experiments, a neutral beam having a duty cycle of 3S ON/ 20S OFF and is modulated at 5Hz, having current of 18–20 A at 100 KeV of...

Now a days, Internet of Things (IoT) is the emerging trend in technology that aims at making our life simpler using sensors and smart devices. All of them are connected to the Internet. Because of this it is possible to access and control them from any place and at any time. The most important aspect in this networking is communication between the smart devices. The correctness in the behavior of...
Today, considerable measure of Research is going ahead in recognition technique of iris images in imperfect environment. The proportion of securing flawed iris pictures in blemished environment is particularly high in light of off-pivot, posture variety, picture obscuring, enlightenment change, Noise and at a separation. In spite of the fact that there are numerous iris acknowledgment systems for...
