In their paper “Design strategies to minimize the radiative efficiency of global warming molecules,” Bera et al. (1) mistakenly equate the relative magnitudes of integrated absorption within the atmospheric window (800–1,400 cm) with relative radiative efficiencies of different molecules. Radiative efficiency is defined as the change in net radiation at the tropopause caused by a given change i...

Abstract The paper presents the results of one-way coupling a large eddy simulation model and an atmospheric composition diffusion complex SILAM. This study investigates possibility time data coarsening (filtering) for use in SILAM microscale calculations. Experiments with scalar tracers limited lifetime are carried out under conditions convective boundary layer. A comparison between calculatio...

business all around the world uses different approaches to know their customers, segment them and formulate suitable strategies for them. one of these approaches is calculating the value of each customer for the company. in this paper by calculating customer lifetime value (clv) for individual customers of an online toy store named alakdolak, three customer segments are extracted. the level of ...

following the changes in the paradigm of urban studies in recent years, sustainability has become an increasingly important issue in the neighborhood’s planning and designing. however, this concept has originally been developed for american and european neighborhoods’ planning, it could also be customized for other neighborhoods’. additionally, in the neighborhood scale, the quality parameter f...

Present study was undertaken to examine the extent of Polycyclic Aromatic Hydrocarbons (PAHs) contamination in neighbourhood lithospheric environment of landfill site situated in eastern outer edge of Kolkata metropolitan city in West Bengal, India, along with its sources identification, spatial distribution and probabilistic cancer risks to residents. The collection and analytical tests were p...

Wind turbines face harsh inflow conditions when operating in the atmospheric boundary layer or wake of other wind turbines. The incoming velocity field can change within seconds due to turbulent structures it contains, resulting a rapid several degrees angle attack for rotating blade. Aerodynamics are hence rapidly altered, leading changes occurring forces on rotor. Such dynamic cause blades tw...

In [4, 13], Bancilhon and Paredaens introduced a notion of completeness for relational database languages on instance-level. Their criterion was subsequently called BP-completeness. Since then, it was used frequently in the context of other database models. However, its application in the context of languages involving object creation appears to raise some serious problems. In this paper, we us...

As opposed to contemporary activity-centric, process-aware information systems (PAIS), for which a multitude of concepts and implementations exist, there is only a very limited number of PAIS implementing data-centric, artifact-centric or object-aware approaches. This demo paper presents the implementation of a modeling environment for the object-aware approach to business process management. O...

From a sample of about 10 φ mesons produced at DAΦNE, we have selected KL mesons tagged by observing KS → ππ decays. We present results on the major KL branching ratios, including those of the semileptonic decays needed for the determination of |Vus|. These branching ratio measurements are fully inclusive with respect to final-state radiation. The KL lifetime has also been measured.

the parallel systems are special important types of coherent structures and have many applications in various areas.in this paper we consider a two-exchangeable-component parallel system for the generalized farlie-gumbel-morgenstern (generalized fgm) distribution. we study the reliability properties of the residual lifetime of the system under the condition that both components of the system ar...
