TL;DR: In this paper, the authors proposed and simulated a new UWB multiple input multiple output (MIMO) circular polarization (CP) antenna with dual T-shaped feed ports at left and right edges to achieve both LHCP and RHCP at same frequency band.
Abstract: It proposes and simulates a new Ultra-wide (UWB) Multiple Input Multiple Output (MIMO) circular polarization (CP) antenna. The developed antenna’s configuration is uncomplicated and incorporates dual T-shaped feed ports at left and right edges to achieve both LHCP and RHCP at same frequency band. A wide circular slot with a hexagonal stub is created in the ground plane in order to achieve better bandwidth for the realization of UWB. The evolution measures of the antenna put forward are presented ahead in this research paper, and its parameters are designed to obtain the optimal return loss, isolation, polarization, and ARBW. Also, a parametric study is done on various types of materials chosen as substrate. The parametric study results, portrays that substrate with higher dielectric tends to give poor ARBW. Operating bandwidth (S11 < = –10db) of the planned antenna is obtained to be 6.7 GHz (3.4 to 10.1 GHz). An isolation of more than 15 dB is also achieved. 3 dB ARBW is obtained in the extent of 3.5–5.5 GHz. Furthermore, the circular polarization features of the antenna proposed are favorable. The surface current and radiation patterns obtained illustrates the circular polarization. Both RHCP and LHCP are obtained at the same frequency in this proposed antenna design. This proposed antenna is a solution to orientation problems of transmitter and receiver, complicated designing, multipath fading, and weather penetration. The simulated antenna is a low profile, compact sized antenna simulated for UWB circular polarization and next generation applications.

01 Oct 2018TL;DR: In this article, a composite nonlinear feedback (CNF) control law for an inverted pendulum subject to actuator saturation is proposed for asymptotic tracking of cart position.
Abstract: In this paper, we develop and implement Composite Nonlinear Feedback (CNF) control law for an inverted pendulum subject to actuator saturation. The inverted pendulum mounted over a cart is inherently unstable and nonlinear system. Our aim is to balance pendulum near to its vertically upright position while tracking the cart position for a given setpoint. CNF control law is proposed for asymptotical tracking of cart position and to make the process faster and smoother with fewer oscillations. The key to CNF control technique design is the combination of linear and nonlinear control where linear control gives quick rising time due to low damping ratio and nonlinear control provides high damping ratio to remove the overshoot resulting from linear part during tracking the reference. Simulations are performed to validate the theory and results are discussed.

01 Dec 2014TL;DR: In this article, a hybrid VN embedding (HVNE) is proposed to map multiple VN requests with node and link constraints, which uses K-core decomposition for decomposing the VN into core and edge network.
Abstract: Due to ever growing demand for the Internet resources, the Internet is facing ossification problem. Network virtualization is a promising way of supporting multiple heterogeneous networks onto a single substrate physical network offering solution to the problem. However, embedding Virtual Networks (VN) on a Substrate Network (SN) meeting the resource requirements of VNs and resource constraints of SNs is a challenging task. Here we present, Hybrid VN Embedding (HVNE) maps multiple VN requests with node and link constraints. Our proposal uses K-core decomposition for decomposing the VN into core and edge network. In currently available VNE methods, higher capacity link requests by VN are rejected due to non-availability of a single link of required capacity within the SN resulting in lower acceptance ratio. To improve acceptance ratio path splitting is proposed. In path splitting, higher capacity requests are served by mapping the required capacity to multiple links within the SN resulting in more requests being served and thus improving acceptance ratio and total revenue. Simulation results establishes that the performance of the proposed algorithm is better than earlier methods.

19 Dec 2018TL;DR: The proposed work focuses on the reduction of packet loss during communication and reduces the packet loss using pointer to reduce in size of data the success rate of data transmission and the probability of congestion get reduced.
Abstract: Wireless networks has performed significant role in daily operations as it has been widely used in military & civilian applications. It is also considered in investigation as well as rescue. It has been used in non- permanent meeting places and airports. Apart from these places, in industrial applications and even in personal area networks, WSNs has been applied. MANET is a temporary wireless network in which is having no fixed infrastructure used. Vehicular ad hoc network has been considered the secondary class of MANET. That has been considered the promising review. It is for the future intelligent transportation environment. The proposed work focuses on the reduction of packet loss during communication. To decrease the packet loss, information would be compressed using pointer. In this mechanism the real data could be replaced by the small short keys available in remote table and encoded data would travel over network. Due to reduce in size of data the success rate of data transmission would increase. There would be minimum chances of packet dropping. More over the probability of congestion get reduced. The use of XOR based encryption has provided quick encryption after compression of data.

17 Jul 2019TL;DR: Analysis of different power factor Correction topologies is done to understand their various techniques like passive and active and after that types of active power factor correction types are visualized and analyzed.
Abstract: With the advent of technology the use of power electronic devices rapidly increasing. Most of the power electronic devices require the rectifier i.e. AC- DC power converter for their working or charging purposes. Use of the power electronic converters introduces harmonics in the system thereby violating the limits of the international standard and also as the power level increases the harmonics of lower order which will deteriorates the power factor and thus affects the efficiency to a great extent. All these problems arises a great need of power factor correction. Here, in this paper analysis of different power factor correction topologies is done to understand their various techniques like passive and active and after that types of active power factor correction types are visualized and analyzed. The simulation result of the PFC buck and PFC boost converter communicate that both the techniques help to improvise the power factor.
