Rapid growing of multimedia processing technologies enables many creative and powerful new applications. Due to the availability of multimedia reconstruction and editing tools, multimedia authentication gained a considerable attention. Some authentication is to be performed during the transmission of data via insecure networks. Data encryption is one of the frequently used method for secure data transmission...
Perpendicular Spin-Transfer Torque (STT) MRAM is a promising technology in terms of read/write speed, low power consumption and non-volatility, but there has not been a demonstration of high density manufacturability at small geometries. In this paper we present an unprecedented demonstration of a robust STT-MRAM technology designed in a 2x nm CMOS-embedded 40 Mb array. Key features are full array...
Recently perceived vulnerabilities in public key infrastructures (PKI) demand that a semantic or cognitive definition of trust is essential for augmenting the security through trust formulations. In this paper, we examine the meaning of trust in PKIs. Properly categorized trust can help in developing intelligent algorithms that can adapt to the security and privacy requirements of the clients. We...
Ultra-sensitive detection of bio-chemical molecules is a topic of immense recent research interest. Accordingly, there has been several reports of detection of DNA and proteins using Graphene field effect transistors (GFET). In spite of these exciting results, surprisingly, the theoretical understanding of GFET biosensors is still not fully developed to the extent that new experiments could be designed...
Perovskite based p-i-n solar cells are now increasingly explored among the photovoltaic research community due to its excellent power conversion efficiencies. Accordingly, diverse materials and processing conditions are being explored to overcome some of the limitations like low fill factor, stability, and hysteresis issues. Interestingly, the performance of such p-i-n based solar cells is critically...
Variability in the transistor parameters play a significant role in CMOS scaling to nanometer feature sizes. New channel materials such as silicon-germanium for pFET at 32nm and beyond are useful because of higher mobility and lower threshold voltage. However, gate-induced drain leakage (GIDL) is dominant in the total leakage and the use of germanium (Ge) may introduce additional variability sources...
Rubber tree tapping is considered to be a skill oriented job and the availability of such labors are getting worse day by day. This is considered to be the one of the reason which affected the natural rubber productivity from Indian plantations. Even though cheap unskilled labors are available, they cannot be used for tapping by using the traditional V groove knife or Jabong knife. So this paper discusses...
Hevea brasiliensis/Rubber tree is considered to be the most predominant plantation crop in Kerala which was found to be the major source of income for the 11.5 lakh planters within Kerala. Due to the availability of natural rubber from foreign countries at cheaper price, the current market price as well as the demand of Indian rubber is decreasing. Unfortunately in addition to low income from rubber,...
A price based spectrum sharing scheme is considered where a primary user allows certain secondary users to access its unused licensed band opportunistically or with coexistence. While in coexistence, network of multiple users, competing for the same idle spectrum, ends up causing intolerable interferences to the primary receiver. Since PU is of prior importance, any kind of interruption to its transmission...
Traditionally, the visually challenged are forced to study only humanities or arts at pre-university level and beyond, due to inadequate educational curriculum, accessibility denied campuses, lack of empowering assistive technologies and ignorance on the needs of vision deprived children. Unemployed among the blind is as high as 98%. IEEE Professionals of Kerala networked with Chakshumathi, the NGO...
A developing economy's rate of economic growth and number of jobs generated in the country is determined by the knowledge and skill of the prevailing workforce. Such an economy needs a well-designed and comprehensive strategy to enhance employability of its youth including students by focusing on creating a database of vocational engineering skills available in the country, expansion of avenues to...
In recent times audio watermark has become the centre of attention due to rapid growth of data transmission rates on internet, which has often allowed the unauthorized usage of digital audio files. This paper proposes a Discrete Wavelet Transform (DWT) based blind audio watermarking system. The initial audio undergoes wavelet based approach and later we divide it into frames. Here Fibonacci numbers...
Visualization of geographic data finds enormous applications in location finding, disaster management, resource allocation, mobility pattern detection etc. In this Big Data era, location information is embedded in most of the available data. While many general purpose visualization tools available today fail to scale when handling big data and also lack visually appealing output, this paper aims to...
Rough Set Theory is widely used for successful decision making. Problems of real life situation demands multiple way decisions and conventional two way decision system have to be refined to make effective decisions. From the lower and upper approximations of Pawlak Rough Set model, three disjoint regions in the universe have been derived and a three way view model for decision making is proposed in...
Innovative developments in computer technology has made distribution of data easier. But it has also put forth a new challenge to secure these multimedia data from privacy. In any kind of information system, data security and confidentiality services are generally required. In this paper we present a new secure audio watermarking technique based on Fast Fourier Transform (FFT) along with encryption...
Cognitive Radio (CR) is a promising technology to alleviate spectrum scarcity problem. CR enables a technique called spectrum leasing where the secondary users able to access licensed spectrum bands opportunistically by making monetary payment. A three phase spectrum leasing scheme is considered where primary user allows users in a distributed secondary network to access its licensed band either in...
Shadow is formed by the interaction of light with object. Effect of shadow is very crucial in the case of satellite image processing. Roads, buildings, trees etc are detected for various applications. But the interference of shadow makes mismatching of these objects. Several algorithms are being developed to detect and reconstruct the shadow region. This paper presents a Shadow detection technique...
In spite of the excellent reported efficiencies, perovskite based solar cells are still plagued by concerns related to stability and hysteresis. While the major physical phenomena related to carrier generation and transport are fairly well understood through theoretical models and simulations, the crucial role of interfaces is not well explored in the community. In this manuscript we show, through...
Integration of microgrids to grid with the help of modern power electronic devices disturbs the grid stability. For improved integration and power sharing, a knowledge based algorithm using the concept of smart parks is introduced in this paper. Smart parks are electric vehicle charging centers which have a great potential to support the grid. Smart parks uses modified Icosφ control algorithm and...
Hyperspectral imaging(HI) is an emerging technology in the field of biomedical engineering which may be used as a non-invasive modality for cancer characterization. In this project, we propose to investigate hyperspectral imaging for the characterization of gastric cancer. The hyperspectral imaging has been used for the detection of various kinds of human cancer; breast, gastric, prostate and tongue...
