urbanization, population growth and moving from traditional manufacturing industry to accelerate the process of economic development and parallel, significant environmental impacts are left. the purpose of this study is to investigate the effect of different variables such as trade openness, comparative advantage, production levels and other important variables affecting the emission of carbon ...

an ever-increasing drift of energy consumption, unequal geographical distribution of natural wealth and the quest for low carbon fuel for a cleaner environment are sparking the production and use of biodiesels in many countries around the globe. in this work, jatropha and karanja biodiesels were produced from the respective crude vegetable oils through transesterification, and the different phy...

We investigate the ideas that a sizable fraction of the interferometrically unresolved infrared emission of the nucleus of NGC 1068 might originate from other processes than thermal dust emission from the torus. We examine the contribution of free-free or synchrotron emissions to the central midand near-IR parsec-scale emitting region of NGC 1068. Each mechanism is constrained with parsec scale...

Compressed sensing (CS) aims to recover images from fewer measurements than that governed by the Nyquist sampling theorem. Most CS methods use analytical predefined sparsifying domains such as total variation, wavelets, curvelets, and finite transforms to perform this task. In this study, we evaluated the use of dictionary learning (DL) as a sparsifying domain to reconstruct PET images from par...

An Industrial and Enterprise Greenhouse Gas Emission Data Analysis System, which meets with the need of those giant energy-consuming enterprises, has been set up through a series of studies about Greenhouse gas (GHG) verification method in industries such as cement, thermal power, cogeneration, transportation, sewage treatment etc. The analysis system consists of six modules: Organization struc...

Medical image reconstruction from projections is computationally intensive task that demands solutions for reducing the processing delay in clinical diagnosis applications. This paper analyzes reconstruction methods combined with preand post-filtering for Single Photon Emission Computed Tomography (SPECT) in terms of convergence speed and image quality. The evaluation is performed by means of a...

The concept of Extended Floating Car Data (xFCD) allows to analyse traffic-related CO2 emissions by reading out electronics of cars. In urban environments, CO2 peaks caused by traffic congestion or inept traffic infrastructure are of special concern. This paper gives an overview of GISbased methods and workflows that can be applied to xFCD in order to appropriately detect those emission peaks. ...

Recently correlation analyses between Galactic dust emission templates and a number of CMB data sets have led to differing claims on the origin of the Galactic contamination at low frequencies. de Oliviera-Costa et al (1999) have presented work based on Tenerife data supporting the spinning dust hypothesis. Since the frequency coverage of these data is ideal to discriminate spectrally between s...
