Web page recommendation system is one kind of the recommendation system based on the user's current web navigation behavior that automatically recommends web pages in which a particular user is most interesting. For effective web page recommendations, it is very crucial and difficult to find the useful and sufficient knowledge from web usage data. This paper discusses taxonomy of recommendation system...
The heavy traffic congestion problem in major cities and towns is mainly attributed to the time spend across crowded traffic junctions especially during peak hours. The traffic across junctions is controlled by signaling patterns, where the signal duration is invariably static in nature. The traffic density across either sides of the road does not affect the duration of signal. For reducing the time...
With fashion industry included e-commerce (worldwide) is expected to hit the $35 billion mark by 2020. There's a need for applications which help the user in making intelligent decisions on their day to day online purchases. In this paper, our aim is to build a system that would be able to understand fashion and the user to provide personalized clothing recommendations to the user. Our approach includes...
Diabetic Retinopathy is human eye disease which causes damage to retina of eye and it may eventually lead to complete blindness. Detection of diabetic retinopathy in early stage is essential to avoid complete blindness. Many physical tests like visual acuity test, pupil dilation, optical coherence tomography can be used to detect diabetic retinopathy but are time consuming and affects patients as...
Object recognition in digital images are carried out using syntactic or spectral domain pattern recognition techniques. Due to ever increasing size of data collected by digital image acquisition systems there is a need to go in for developing faster, reliable and intelligent pattern recognition methods which would mostly supplement human intelligence in recognizing objects which otherwise remain latent...
In mobile multimedia communication systems, the limited bandwidth is an issue of serious concern. However for the better utilization of available resources in a network, channel allocation scheme plays a very important role to manage the available resources in each cell, hence this issue should be managed to reduce the call blocking or dropping probabilities. In this paper we have proposed the new...
Social network emanates from socially interacting entities that are represented as nodes with identical properties. These nodes are interconnected through different forms of relationship among them. Social network analysis (SNA) establishes interactions and defines the relationships on basis of theoretical foundation of networks and graphs. Social media involves in exploring several ways people share...
Orthogonal frequency coding is often used for surface acoustic wave (SAW) based systems. This paper presents the theoretical analysis of orthogonal frequency coding technique used with on-off keying in communications systems. The interference encountered in multiuser environment is formulated and a code selection criterion for minimizing the interference is proposed. The analytical expression for...
The military wireless systems often have specific constraints such as achieving very good receiver sensitivity, very high tolerance to frequency shifts and best possible dynamic range. Direct spread spectrum (DSS) is the proven threat free technology in many militarized wireless systems, which will also gives the advantage of good receiver sensitivity because of spreading gain it offers. The RF dynamic...
Clustering is an important technique that helps in reducing the network energy consumption. The Cluster Head (CH) usually performs data fusion, aggregation and communication of the aggregated data to the Base Station. As the CHs communicate with the Base Stations located at larger distances than the member nodes, they generally consume more energy. This leads to energy drainage of CHs at a faster...
IOT features created various new information parts but one of the part is vehicular information network where many cars and products are participating with huge info exchange. The high information management as well as minimal transmission efficiency sustained in the vehicular information network is challenging the investigators to analyze more cost-effective and scalable network architectures along...
Wireless Sensor Networks (WSNs) are made up of number of sensor nodes which can sense the physical quantity, process it and transmit/receive it to base station (BS) via single hop and multiple hops. These sensor nodes needs the power or energy to operate which is generally provided by battery. since these batteries have limited amount of energy so energy consumption in sensor network is a serious...
Bi Swapped Networks (BSN) is a symmetrical hybrid Opto-electronic network architecture related to the family of Swapped/OTIS interconnection networks. In fact, the symmetrical nature the network supports ease of design and implementation of parallel algorithms in comparison to its well known counterpart asymmetrical Opto-electronic network named OTIS networks. BSN mesh contains 2n4 copies (n represents...
The paper exhibits a novel design of stair cased shaped fractal antenna for multiband applications. The antenna is designed on FR4 glass epoxy substrate with parameters like thickness 1.6mm, dielectric constant 4.4 and resonant frequency 3.8GHz. Proposed antenna is simulated and coaxial feed is used to analyze its performance. Maximum value of gain observed is 7.51dB. The HFSS version 13 software...
A Mobile ad-hoc network comprises mobile nodes that communicate with one other without any aid from a fixed infrastructure. Every hub itself goes about as a switch for transferring and getting packets to/from different terminals. The nodes in the network are mobile in nature and are driven by battery. If a node moves out of the radio range of the other node there are probable chances of link breakage...
Digital filters play a vital role in the era of digital communication system. Digital bandpass filter basically provide high attenuation to the unwanted frequency components in stop band and offer very low or ideally zero attenuation to desired signal components in passband when its impulse response is adjusted as per required specifications. The selection of an appropriate Field Programmable Gate...
In this paper, a modified successive interference cancellation (SIC) scheme is designed for multiuser detection in multicarrier code division multiple access (MC-CDMA) communication systems. Successive interference cancellation (SIC) is used to mitigate the multiple access interference (MAI) which occurs in MC-CDMA systems. SIC uses the decision feedback concept where the signal from a user is regenerated...
In this paper, a novel modified Particle Swarm optimization (mPSO) technique is proposed for multiuser detection (MUD) which is performed for multicarrier code division multiple access (MC-CDMA) communication systems. In MC-CDMA systems the users have their own spreading codes. The users also share same frequency band simultaneously which allows the system to transmit data at higher rate but the problem...
Wireless sensor networks consists of tiny sensor nodes deployed in various geographic conditions to gather the information about the environment. The distributed and unattended environment makes the network more prone to security breaches. Rather than many studies discuss many potential issues of WSN security and detection mechanisms, most of these are discussed in isolation. An attempt has been made...
Wireless sensor networks (WSNS) is a collection of sensor nodes whose basic functionality is to monitor the region in which they are deployed. Main research issues in designing a protocol for WSNs is, how to minimize energy consumption and prolong the network lifetime, while ensuring the required coverage as well as connectivity. In this paper, we present a coverage and connectivity aware data gathering...
