PGA based product development companies need third party IP cores to complete the product design time effectively and cost effectively. The one-time payment upfront licensing of IP cores is impractical for FPGA based products, which does not benefit either IP core vendors or product engineering companies. There is a need for good competitive pricing scheme which benefit product development companies and also secure the revenue to IP core vendors. The Pay-per-Device (PPD) pricing model scheme...

The research on magnetoelectric composites has been busted up by their potential applications in microwave devices, sensors, transducers, information storage, spintronics and multiple-state memories. In the present work, ferroelectric BaTiO3 (BT) - ferromagnetic NiFe2O4 (NF) composites were prepared by different powder synthesis route namely solid-state, auto-combustion, and hybrid precipitation to tailor the phase connectivity of the constituent phases. Functional properties (dielectric, pie...

Abrus agglutinin (AGG), a type II ribosome-inactivating protein has been found to induce mitochondrial apoptosis. Initially, we documented that AGG-mediated Akt dephosphorylation led to ER stress resulting in the induction of autophagy-dependent cell death through the canonical pathway in cervical cancer cells. At the molecular level, AGG induced ER stress in PERK dependent pathway and inhibition of ER stress by salubrinal, eIF2a phosphatase inhibitor as well as siPERK reduced autophagic deat...

Magnetic and dielectric properties exhibited by magneto-dielectric composite systems can be tunable using electrical and magnetic fields due to mechanical coupling effect, which may led to potential application such as electrically readable magnetic memories, phase shifters, miniature antennas and magnetic sensors. The mechanical coupling effect strongly depends on morphology of the phases (magnetic and dielectric) present in the composites along with their orientation and interaction, which ...

Brain-computer interface (BCI) P300 speller can be used as a powerful aid for severely disabled people in their everyday life. The character recognition using P300 speller involves two stages for classification. First stage is to detect the P300 signal and second one is to determine the right character from the detected P300. Classification of P300 is a challenging task in character recognition process. Ensemble of classifiers is a robust method for classification as it reduces the classifier...

Link prediction is an important research direction in the field of Social Network Analysis. The significance of this research area is crucial especially in the fields of network evolution analysis and recommender system in online social networks as well as e-commerce sites. This paper aims at predicting the hidden links that are likely to occur in near future. The possibility of formation of links is based on the similarity score between pair of nodes that are not yet connected in the social...

This paper proposes a gray level run length matrix (GLRLM) based feature extraction technique for the detection of Acute Lymphoblas-tic Leukemia (ALL). ALL could be a fatal hematopoietic ailment which might cause death if it's not treated at the early stage. The GLRL matrix is a method for extraction of statistical textural features from the nucleus of the lymphocyte image. The extracted features are then supplied to the Support Vector Machine (SVM) for classi_cation. The experiments are perf...

In the present era, polymer composites are widely used as various structural parts in marine field. In order to check the suitability of these materials in marine applications it is very much essential to know about the water/moisture absorption behaviour of these composites which is strongly correlated with the extent of degradation of properties of these materials when exposed to water. Considering this, the keystone of this present work is to explore the effect of moisture absorption ...
