Propagation Characteristics of Superconducting Slot Line Based on Ferroelectric Substrate

Abstract: This paper deals with the microwave propagation characteristics of a superconducting slotline waveguide structure supported by a ferroelectric thin film The variation of the propagation constant and attenuation constant with biasing electric field was theoretically studied using the spectral domain method The dependence of the propagation characteristics on the operating frequency and temperature was investigated The influence of geometrical parameters like thickness of the ferroelectric thin film, width of the slot, and thickness of superconducting strip constituting slot was analyzed at different biasing electric fields

Word-Level Script Identification from Scene Images

Abstract: Script identification on camera based bus sign boards are presented in this work. The text localization is achieved by a series of morphological operations. Number of texture features, such as gabor features, log-gabor features and wavelet features are extracted from the segmented text images to classify the text images into three scripts, English, Kannada and Malayalam. Three different classifiers are evaluated and results are reported in this work.

The Sparing Number of the Cartesian Products of Certain Graphs

Abstract: Let $\mathbb{N}_0$ be the set of all non-negative integers. An integer additive set-indexer (IASI) is defined as an injective function $f:V(G)\rightarrow \mathcal{P}(\mathbb{N}_0)$ such that the induced function $f^+:E(G) \rightarrow \mathcal{P}(\mathbb{N}_0)$ defined by $f^+ (uv) = f(u)+ f(v)$ is also injective, where $f(u)+f(v)$ is the sumset of $f(u)$ and $f(v)$ and $\mathcal{P}(\mathbb{N}_0)$ is the power set of $\mathbb{N}_0$. If $f^+(uv)=k \forall ~ uv\in E(G)$, then $f$ is said to be a $k$-uniform integer additive set-indexer. An integer additive set-indexer $f$ is said to be a weak integer additive set-indexer if $|f^+(uv)|=max(|f(u)|,|f(v)|) \forall ~ uv\in E(G)$. In this paper, we study about the sparing number of the cartesian product of two graphs.
