We are interested in a stochastic model of trait and age-structured population undergoing mutation and selection. We start with a continuous time, discrete individual-centered population process. Taking the large population and rare mutations limits under a well-chosen time-scale separation condition, we obtain a jump process that generalizes the Trait Substitution Sequence process describing A...

the impact assessment method seeks to bring about a more ecologically, socio-culturally and economically sustainable and equitable environment. determining the main factors affecting the attitudes of stakeholders is crucial for understanding the impacts of development plans. this approach helps planners and decision makers to identify the values and traits of stakeholders and accelerate the dif...

Structural equation modelling (SEM) can illuminate complex interaction networks of the sort found in ecology. However, selecting optimally complex, data-supported SEM models and quantifying their uncertainty are difficult processes. To this end, we recommend a formal model selection approach (MSA) that uses information criteria. Using suite numerical simulations, compare MSA-SEM against two tra...

Modelling the Brand Equity is a must for any corporate. How much brand worth? Brands dijfer in their power and value market place. estimated of premium customers are willing to pay using branded product compared an unbranded product. intangible assets it difficult measure directly. Brands, however, do not necessarily last forever Hence important that they monitored over period time. Structural ...

The size of international software industry is over $1000bn. Total revenue earned by the Indian software industry in year 2005 was $30bn and which is expected to grow. The price quoted by vendors to its customers and the rate of the customer service is dependent on the productivity of the project. Given the fact that software development complexity is on an ever-increasing curve, it becomes cri...
