Owing to its severe effect on productivity of rain-fed crops and indirect employment as well per capita income, agricultural drought has become a prime concern worldwide. The occurrence is mainly climatic phenomenon which cannot be eliminated. However, effects can reduced if actual spatio-temporal information related crop status available the decision makers. present study attempts assess efficiency remote sensing GIS techniques for monitoring extent drought. In study, NOAA-AVHRR NDVI data...

High‐resolution soil moisture holds the key to improving weather forecast, drought monitoring and hydrological modelling. Therefore, present study investigates potential of temperature/vegetation dryness index (TVDI) from MODIS assess status in sub‐humid parts India (western Uttar Pradesh). The TVDI was calculated by parameterizing normalized difference vegetation index–surface temperature space 8 day reflectance surface products. Correlation regression analysis carried out relate against...

The largest eigenvalue of the adjacency matrix a network (referred to as spectral radius) is an important metric in its own right. Further, for several models epidemic spread on networks (e.g., ‘flu-like’ SIS model), it has been shown that dies out quickly if radius graph below certain threshold depends model parameters. This motivates strategy control by reducing underlying network.In this paper, we develop suite provable approximation algorithms removing minimum cost set edges (modeling...

A GIS‐aided multi‐criteria evaluation (MCE) approach in land suitability analysis for crops was described this study and used to suggest suitable cropping patterns a flood prone area, the Bogra district of Bangladesh. The major objective an optimal pattern combat adverse effects using integrated derived by spatial (SMCE) analytical hierarchy process (AHP). For analysis, Rice (Aman), Mustard, Potato Wheat crops, which were prominent selected study. IRSP6: LISS III satellite data generate post...

Attackers, in particular botnet controllers, use stealthy messaging systems to set up large-scale command and control. To systematically understand the potential capability of attackers, we investigate feasibility using domain name service (DNS) as a command-and-control channel. We describe quantitatively analyze several techniques that can be used effectively hide malicious DNS activities at network level. Our experimental evaluation makes two-month-long 4.6-GB campus data 1 million names...

Given a network with groups, such as contact-network grouped by ages, which are the best groups to immunize control epidemic? Equivalently, how choose communities in social media like Facebook stop rumors from spreading? Immunization is an important problem multiple different domains epidemiology, public health, cyber security, and media. Additionally, clearly immunization at group scale (like schools communities) more realistic due constraints implementations compliance (e.g., it hard...

Regional estimates of crop yield are critical for a wide range applications, including agricultural land management and carbon cycle modelling. Remotely sensed images offer great potential in estimating extent over large areas owing to their synoptic repetitive coverage. Over the last few decades, most commonly used yield–vegetation index relationship has been criticized because its strong empirical character. Therefore, present study was mainly focused on regional wheat by remote sensing...

Detection of crop water stress is crucial for efficient irrigation management. Potential Satellite data to provide spatial and temporal dynamics growth conditions makes it possible monitor at regional level. This study was conducted in parts western Uttar Pradesh Haryana. Multi-temporal Landsat were used detecting wheat using vegetation indices (VIs), viz. index (VWSI) land surface wetness factor (Ws_LSWI). The estimated from satellite data-based VIs validated by (Ws) derived flux-tower...

Let $\mathfrak{f}$ be a transcendental entire function with hyper-order less than one. The aim of this note is to study the value distribution differential-difference monomials $\alpha \mathfrak{f}(z)^{q_0}(\mathfrak{f}(z+c))^{q_1}$, where $c$ non-zero complex number and $q_0\geq2,$ $q_1\geq 1$ are non-negative integers, $ \alpha(z)$ $(\not\equiv 0,\infty)$ small $\mathfrak{f}$.

INTRODUCTION: In vitro fertilization (IVF) is a common form of assisted reproductive technology. While current embryo selection focuses on morphology and genetic aneuploidy, examining nucleic acids in blastocoel fluid may provide an additional molecular marker for selection. The project aims to assess the epigenetic state cell-free DNA contained fluid-conditioned media from day 5 human embryos profile post-translational modifications histones associated with apoptosis. METHODS: Blastocoel...

Soil organic carbon (SOC) is an important and reliable indicator of soil quality. In this study, spectra were characterized analysed to predict the spatial content using multivariate predictive modeling technique-artificial neural network (ANN). EO1-Hyperion (400 - 2500 nm) hyperspectral image, field laboratory scale data sets (350 generated which consisted estimated SOC collected samples (dependent variable) their corresponding reflectance sensitive spectral bands (predictive variables)....

The study of the spatial patterns and temporal changes cropland is important to understand underlying factors functional effects agricultural landscape. On other hand, crop dynamics mapping essential know overall agro-spatial diversity area. Therefore, this paper addressed a spatio-temporal analysis cropping pattern change in Bogra district Bangladesh over last 16 years (between 1988/89 2004/05). In paper, from multi-temporal multi-sensor satellite images was described. Landsat TM IRS P6...

In this paper, we conduct a systematic study of human-initiated cascading failures in three critical inter-dependent societal infrastructures due to behavioral adaptations response crisis. We focus on closely coupled socio-technical networks here: (i) cellular and mesh networks, (ii) transportation (iii) mobile call networks. crises, changes individual behaviors lead altered travel, activity calling patterns, which influence the transport network loads wireless The interaction between these...
