Internet is considered as the worldwide system of many computers and their networks which are linked together by wired or wireless media. Network is based on internet protocol suite which has a model known as Transmission Control Protocol/Internet Protocol (TCP/IP) and a set of protocols. Model consists of TCP and IP as major protocols at transport and network layer respectively. TCP deals with end to end transmission and reassembly of packets. It also focuses on reliable and orderly transmission of packets. There are many TCP variants which are used in communication, such as Reno, Binary Increase Congestion control (BIC) and Vegas. TCP poses many issues like end to end delay in communication, congestion, connection management between sender and receiver end points. Congestion being one of the important issues affects the Quality of Service (QoS) of network and reduces overall network performance because of buffering of data in queue. Different Active Queue Management (AQM) algorithms which handle congestion are Random Early Detection (RED), Proportional Integral controller Enhanced (PIE), Controlled Delay (CoDel). These algorithms efficiently drop the packets when the buffer gets full or when it is near to full based on packet drop signal or other mechanisms. The article discusses about the importance of the right choice of TCP and AQM variant, results have been obtained by practical setup using flent and netpef traffic generator. The proposed work considers the study of different TCP and AQM variants for effective congestion control. Comparative study is conducted by considering selected TCP variant along with different AQM techniques. It reveals that TCP BIC along with CoDel provides less Iatency, high throughput and minimum packet drops.

A modified bulk degeneration technique for source-degenerated OTAs is proposed in this paper. The approach employs drain voltage division and cross-coupling the resultant voltage to the bulk terminal of differential pair which reduces third harmonic distortion (HD3). Simulations are carried on 0.18 $mu {rm m}$ process with 1.8 V power supply which shows that (HD3) is decreased by 14 dB (for frequencies of 100 KHz) as compared to previously reported bulk degenerated transconductors. An added advantage is the variation of DC transconductance using the resistance ratio of the voltage divider circuit which offers the tunability in the transconductance.

Visible Light Communication (VLC) technology is an emerging technology which promises to offer high data rate, last mile solution, ubiquitous communications, and relief to the most congested radio frequency RF system. Recently, VLC has drawn the attention of researchers around the globe and they are still exploring the applications and services which can be offered by this technology. In this work, a conceptual architecture of hybrid technology that is, VLC with RF is presented and discussed for vehicular environment. The idea is to provide relief to RF spectrum by using downlink signal with VLC technology and uplink transmission using RF. This RF could be a cellular system and/or wireless local area networks (WLAN) working as road side unit (RSU). Analysis is presented to show the VLC system would offer ubiquitous communication on road throughout the driving while illuminating road for the safe drive. Through simulation results, it is shown that the system offers high data rate in the downlink. However, for the uplink, road side units from RF technology based system offer the access to data services.

Human brain is the command centre of the human body. It receives input from sensory organs and sends outputs to the muscles. Brain consists of two types of tissue mainly white matter tissue (anisotropic) and grey matter tissue (isotropic). Active examining of the brain functioning requires certain brain imaging techniques. In order to solve this problem Magnetic resonance imaging (MRI) technique was implemented for the imaging of grey matter of the brain. In 1994 Peter Baser introduced Diffusion Tensor Imaging (DTI), DTI is an advanced variant of MRI which is being implemented for the imaging of white matter tissue of the brain. It uses present MRI technology and no other equipment is required. DTI technique undergoes visualization of the random motion of the water molecules in the white matter tissue of the brain. The random motion of the water molecules can determine the anisotropic and isotropic nature of the white matter portion of the brain. The parameter of analysing the isotropic and anisotropic range is the Fractional Anisotropy (FA). Here, three visualization techniques for DTI namely Scalar Indices, Tensor Glyph, and Fibre Tractography are studied and analysed. The analysis focuses on extracting useful information of the brain in different aspects. This can be useful in studying the internal patterns of the brain which will help in medical diagnosis.

Magnetic Resonance (MR) imaging is a non invasive medical imaging technique used widely for diagnosis. The data collected by MRI scanner is placed in the k-space. Various algorithms are developed to sample the k-space and reconstruct the image from the compressive sampled k-space data. The k-space sampling pattern plays an important role in optimizing compressed sensing magnetic resonance imaging. CS technique violates the Nyquist’s sampling theory by sampling signals at lower rate than conventional sampling rate. CS can reduce scanning time in MRI applications by acquiring very few samples. This paper analyses the Cartesian variable density k-space data sampling pattern with the radial sampling scheme. Qualitative and quantitative analysis are performed on the reconstructed MR Image for different sampling percentages.

Game-based education is an effective medium to improve the skills and knowledge of the students. Studies have shown that game improves cognitive skills, creates enthusiasm and motivate students to learn the concepts thoroughly. In this study an educational gaming method is created where concepts have been taken from four subjects (English, Physics, Chemistry and General Knowledge) and explained them with the help of games. This method is developed to improve the speed, vocabulary and learning skills of the students. Games are proven to be effective in improving cognitive skills, reasoning and problem solving skills. This article suggests the need to modify the teaching methods by addition of Game-based educational techniques to improve the quality of learning styles of the students.

A metamaterial loaded multiband frequency reconfigurable antenna is reported. The antenna has a size of $0.34lambda_{l} times 0.34lambda_{l} times 0.02lambda_{l}$, at a lower frequency of 3.95 GHz. The antenna consists of two metamaterial, namely, Circular Complimentary Split Ring Resonator (CCSRR) and Hexagonal Complimentary Split Ring Resonator (HCSRR), which independently controls the band at 3.95 and 5.72 GHz, respectively. The proposed antenna shows resonance at 3.95, 5.72 and 8.3 GHz, with fractional bandwidths of about 5.12% (3.8-4 GHz), 2.33% (5.51-5.64 GHz) and 4.22% (8.1-8.45 GHz). Frequency reconfiguration in the proposed antenna is achieved by utilizing two metallic switches, by placing them between the rectangular slot present in the radiating part and the ground plane. When both the switches are ON antenna operates at single band. When either of the switch is ON antenna operates at dual band. When both the switches are OFF, antenna operates at triple band. Acceptable gain, stable radiation pattern and good impedance matching are observed across the operating bandwidths.

The effective permeability and permittivity of the proposed H-SRR is calculated using NRW method and its effectiveness as artificial material is proved. The equivalent circuit of the resonator is modelled considering circular loop approximation and thus realizing the effective inductance. The effective capacitance is calculated considering hexagon as circular capacitor and gap is modelled as parallel plate capacitor. The proposed equivalent circuit is able to predict the resonant frequency with less than 2% error.

The low power successive Approximation Analog to Digital converter (SA-ADC) is widely used in several applications mainly in bio-medical. In this paper, the performance of the 14 bit SAR–ADC analyzed through obtaining the power consumption by adopting the two split capacitive array DAC method. In addition to this, the area utilization and delay performance of two split DAC is also derived. The proposed two split capacitive array DAC with multiplexer switching, consumes the power of 12uW. So totally 190 times of power is reduced by the proposed method in comparison with conventional single split capacitive array DAC. Also this design requires 185 unit capacitances whereas the conventional design utilizes 256 unit capacitances in a capacitive array, thereby reducing the area of CDAC by 28%. In addition to this, the delay performance of the design also analyzed. Here design is made fully differential, hence the noise parameter is considerably reduced. Behavioral simulations were performed to check the effectiveness of design in each stage.
