Restore: An R of sustainability that can tame the “Conundrum”
Get PDFThe environmental benefits of sustainability efforts can be rendered less effective due to economic feedback mechanisms. As a remedy against such rebound effects, a reinvestment strategy towards environmental causes has been suggested. Here, a practical implementation of such a reinvestment strategy is presented. It involves a) estimating the financial savings resulting from sustainability efforts, b) informing the participants that the environmental benefit of the efforts is reduced by economic feedback mechanisms and c) asking them to donate a fraction of the expected savings towards environmental causes. An easy-to-use methodology for estimating rebound effects of sustainability efforts is presented in order to quantify the efficacy of this approach. CO2 emission offsets are used as an example of donations towards environmental causes. It is shown, that donating even a small amount (less than 1% of financial savings obtained from conservation or engineering savings) of donated carbon offsets can more than eliminate the estimated rebound effects. This then leads to the restore principle, that states that the environmental benefit of reducing activities with average environmental impact is dramatically improved if a fraction of the resulting financial savings is applied towards environmental causes. This approach is made practical by augmenting the common reduce, reuse, recycle motto with a fourth component: reduce, reuse, recycle and restore
Fusion of Satellite Images in Transform Domain
Get PDFUnique—Image fusion in light of the wavelet and fourier trans-form comes about rich multispectral points of interest yet gives less spatial subtle elements from source images. Wavelet transform performs well at straight highlights yet not at non-direct discontinuities since Wavelets don't utilize the geometric properties of structures. Curvelet transforms defeat such troubles in include rep-resentation. A novel Image fusion rule by means of high pass balance utilizing Local Magnitude Ratio (LMR) in Fast Discrete Curvelet Transforms domain (FDCT) and Discrete wavelet transform (DWT) is characterized. Indian Remote Sensing Geo satellite images are utilized for MS and Pan images. This fusion rule creates HR multispectral image with high spatial resolution. This technique is contrasted and wavelet, Principal Component Analysis (PCA), Fast Discrete Curvelet Transforms domain fusion strategies. Master postured technique spatially performs alternate strategies and results rich multispectral information
Coupled data assimilation in climate research: A brief review of applications in ocean and land
Get PDFRegions of the cryosphere, including the poles, that are currently unmonitored are expanding, therefore increasing the importance of satellite observations for such regions. With the increasing availability of satellite data in recent years, data assimilation research that combines forecasting models with observational data has begun to flourish. Coupled land/ice-atmosphere/ocean models generally improve the forecasting ability of models. Data assimilation plays an important role in such coupled models, by providing initial conditions and/or empirical parameter estimation. Coupled data assimilation can generally be divided into three types: uncoupled, weakly coupled, or strongly coupled. This review provides an overview of coupled data assimilation, introduces examples of its use in research on sea ice-ocean interactions and the land, and discusses its future outlook. Assimilation of coupled data constitutes an effective method for monitoring cold regions for which observational data are scarce and should prove useful for climate change research and the design of efficient monitoring networks in the future
Global positioning system application for monitoring of the engineering infrastructure facility safety
Get PDFOil and gas companies need to ensure continuous operation of critical equipment, no matter how remote. This means knowing exactly where your fleets and equipment are, how they are performing and identifying problems as they occur. There are number of existing security systems developed to protect linear systems like oil pipelines for transportation of oil and gas products from the first point of development up to collection stations. In the current stage is the gap of the oil and gas pipeline systems security purposes of use of space technology advances. This paper dedicated to the subject of linear pipeline monitoring with use of global positioning system for observation of changes of land in the areas actively functioning of natural disaster factor[1]
The Functional Mechanisms and Clinical Application of Read-Through Drugs
Get PDFAccording to previous reports, nearly one in 10 genetic diseases are caused by nonsense mutations around the world. Nonsense mutations lead to premature transcription terminations in cells, which in turn generate non-functional, truncated proteins. In recent years, read-through drugs are playing increasing prominent roles in the researches related to genetic diseases caused by nonsense mutations. However, due to the fact that the mechanisms lying behind translation termination still remain to be elucidated, the mechanistic research and clinical application of read-through drugs are facing new challenges. This review mainly discusses about the pathogenesis of genetic diseases caused by nonsense mutations, and then introduces the current clinical application of read-through drugs. Finally, we display some problems that remain to be solved and propose some possible coping strategies
Separable Reversible Data Hiding in an Encrypted Image
Get PDFSince times immemorial, security of data to maintain its confidentiality, proper access control, integrity and availability has been a major issue in data communication. Today images and data transfer in mobile phone communication, e-commerce, Pay-TV, sending private e-mails, transmitting financial information and touches on many aspects of daily lives. We wanted to develop a scheme in which the data embedded in an image and the image itself would be secured from any unauthorized access. This scheme would also be a merit in military and medical services.This paper proposed a scheme for separable reversible data hiding technique in an encrypted image. The original image was encrypted using an encryption key. Then, a data-hider hides the data using the data-hiding key. With an encrypted image containing additional data, if a receiver has the data-hiding key, it can extract the additional data though it does not know the image content and if it has the encryption key, it can decrypt the received data to obtain an image similar to the original one, but cannot extract the additional data. If the receiver has both the key it can extract the additional data and recover the original content without any error by exploiting. This results in the security of data and image privacy

Determination of Optimum Annealing Time Durations of Nano Boron Nitride Added MgB2 Superconductors
No full textIn the present study, I have investigated the effect of different annealing time durations of 0.5h, 1h, 2h and 4h (annealing temperature at 700oC) on the electrical, micro structural and superconducting properties of the nano hexagonal boron nitride (hBN) added/doping magnesium diboride (MgB2) superconducting samples. The aim of this work, hBN added MgB2 superconducting bulk samples are determined to find out the optimum sintering time, also investigated how BN addition effects the optimum fabrication conditions. These superconducting samples were prepared by the conventional solid-state reaction method. Experimental techniques of X-ray diffraction (XRD) were used for structural and microstructural examinations. Critical transition temperatures, difference between Tc-onset and Tc-offset, a and c lattice parameter, grain size, bulk density, residual resistivity ratios (RR) and cross-sectional area fractions (AF) of the pure and nano-hBN added MgB2 materials are obtained using a cryostat equipped with a superconducting magnet. All the experimental results notice that the characteristic features improve regularly with the increment in sintering time durations.
Three-dimensional boundary layer flow of nanofluids due to an unsteady stretching surface
Get PDFA numerical solution has been obtained for the unsteady three-dimensional stretching flow and heat transfer due to uncertainties of thermal conductivity and dynamic viscosity of nanofluids. The term of nanofluid refers to a solid–liquid mixture with a continuous phase which is a nanometer sized nanoparticle dispersed in conventional base fluids. The unsteadiness in the flow and temperature fields is caused by the time-dependent of the stretching velocity and the surface temperature. Different water-based nanofluids containing Cu, Ag, and TiO2 are taken into consideration. The governing partial differential equations with the auxiliary conditions are converted to ordinary differential equations with the appropriate corresponding conditions via scaling transformations. Comparison with known results for steady state flow is presented and it found to be in excellent agreement
QUANTUM META-THEORY (Twisting the Tail of Schrödinger’s Cat)
Get PDFThe problem of Schrödinger’s Cat has figured prominently in the debates about the bearing of quantum physics on our understanding of physical reality. On its basis, various theorists have maintained the quantum physical world exhibits a probabilistically indecisive physical reality. The analysis of the paper that this appeal to quantum reality is methodologically at odds with and disjoint from its underlying approach to quantum theory itself. If there is to be methodological uniformity at this juncture it will have to be along the lines that Einstein always focused—an incomplete hidden factor (perhaps better than “hidden variables”) approach
