Stochastic variability of biological processes and uncertainty of stock properties compel fisheries managers to look for tools to improve control over the stock. Inspired by animals exploiting hidden prey, we have taken a biomimetic approach combining catch and effort in a concept of Bayesian regulation (BR). The BR provides a real-time Bayesian stock estimate, and can operate without separate ...

The fish stock of common sole in the Adriatic Sea has been analyzed by agent-based modeling and simulation techniques in order to integrate other classical stock assessment models. In this work we start investigating also about the formal probabilistic modeling of our case study in order to extract valuable biological information from available formal verification techniques. In particular a PR...

Trophic mass-balance models of ecosystems constructed using the Ecopath approach and software include the diet composition of functional groups as model inputs, and trophic level estimates for these same groups as a model outputs. The well-documented 0.34% enrichment of lSN/14N that occurs at each feeding step in food webs can be used to determine trophic level as well. This contribution is the...

Mass movements in Brazil are common phenomena, especially during strong rainfall events that occur frequently in the summer season. These phenomena cause losses of lives and serious damage to roads, bridges, and properties. Moreover, the illegal occupation by slums on the slopes around the cities intensifies the effect of the mass movement. This study aimed to develop a methodology that combine...

intellectual capital is most vital enabler of enterprises. managing intellectual capital effectively can greatly enhance the competitive advantages of any enterprises. this study focused on how the enterprises utilize intellectual capital, in order to strengthen the competitiveness of enterprises. this research established a novel assessment model to measure the performance of intellectual capi...

  Length composition data (fork length) of kawakawa (Euthynnus affinis ), landed between April 2003 to March 2005 in Coastal Waters of Hormozgan province in Iran ( Persian Gulf and Sea of Oman) , were monthly used to estimate the p opulation parameters and for the assessment of the stock. The growth parameters of von Bertalanffy equation were estimated as L∞: 87.66 cm, K: 0.51 per year and t0: ...

This paper examines the correlation between the relative financial strength of public firms and their stock price performance. By using financial information obtained from the firms’ publicly available financial statement as inputs and outputs in Data Envelopment Analysis (CCR model), a relative financial strength of a firm is determined relative to other competing firms operating in the same m...
