Multi-criteria shortest path problems (MSPP) are called as NP-Hard. For MSPPs, a unique solution for optimizing all the criteria simultaneously will rarely exist in reality. Algorithmic and approximation schemes are available to solve these problems; however, the complexity of these approaches often prohibits their implementation on real-world applications. This paper describes the development ...

we show that when both sources ( lepton flavor violation sources and cp-violating phases) are present, the electric dipole moment of the electron, $d_e$, receives a contribution from the phase of the trilinear $a$-term of staus, $phi_{a_ au}$. for $phi_{a_ au}=pi/2$, the value of $d_e$, depending on the ratios of the lfv mass elements, can range between zero and three orders of magnitude a...

Metadata should help users to assess the quality (fitness for use) of geospatial data, thus reducing the risk of data misuse. However, metadata presents limitations and remain largely unused. There still exists a need to provide information to users about data quality in a more meaningful way. This research aims to dynamically communicate quality information to the users in a rapid and intuitiv...

a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...

Geographical information system (GIS) is a powerful tool in managing and presenting spatial referenced data science it has a lot of geographic functions such as data integration, mapping, overlaying, buffering, projection....etc, but on the contrary it is a limited tool in decision aiding of spatial decision problems. It can't stand alone in taking decision in spatial problem environment. In th...

Until recently Geographic Information Systems (GIS) have held center stage in the archaeologist’s geospatial toolkit, and there is no doubt that archaeologists have moved beyond the map – but into what? In the early years, criticisms voicing GIS as environmentally-deterministic were abundant. What methods and tool have archaeologists used to overcome these criticisms? New geospatial technologie...
