An environment for protecting the privacy of e-shoppers
Privacy, an everyday topic with weekly media coverage of loss of personal records, faces its
bigger risk during the uncontrolled, involuntary or inadvertent disclosure and collection of
personal and sensitive information. Preserving one's privacy while e-shopping, especially
when personalisation is involved, is a big challenge. Current initiatives only offer customers
opt-out options. This research proposes a `privacy-preserved' shopping environment (PPSE)
which empowers customers to disclose information safely by facilitating a personalised e-
shopping experience that protects their privacy. Evaluation delivered positive results which
suggest that such a product would indeed have a market in a world where customers are
increasingly concerned about their privacy
Simulation of Levelized Costs of Electricity Considering Externalities
This research presents long-term projects. Applies stochastic models using Monte Carlo simulation to identify the impact that changes have in the input parameters on the output variable (LCOEE). Uses tornado analysis to identify the impact of the input variables. The results show that; in thermoelectric coal plant, the LCOEE is more sensitive to changes in the price of CO2 emissions than discount rate. In the combined cycle, the LCOEE is most sensitive to the plant factor than CO2 emissions price, discount rate. In the nuclear power plant, the discount rate has greater impact on the LCOE than overnight cost.聽 In contrast to previous work, this research uses Mexico鈥檚 country-risk in the discount rate. This research鈥檚 limitation is that the costs related to transmission, distribution, and backup fee are not included. Concluding that stochastic models provide useful information for decision-making by incorporating historical data and projections of the main variables that could affect the output variable (LCOEE).Simulaci贸n de costos nivelados de electricidad considerando externalidadesEsta investigaci贸n presenta proyectos de largo plazo. Aplica modelos estoc谩sticos mediante simulaci贸n de Monte Carlo para identificar el impacto que los cambios en los par谩metros de entrada tienen en la variable de salida (LCOEE). Utiliza an谩lisis de tornados para identificar el impacto de las variables de entrada. Los resultados muestran; en termoel茅ctrica de carb贸n, que el LCOEE es m谩s sensible a los cambios en el precio de las emisiones de CO2 que a la tasa de descuento. En el ciclo combinado, el LCOEE es m谩s sensible al factor de planta que al precio de las emisiones de CO2. En la central nuclear, la tasa de descuento tiene mayor impacto en el LCOE que el costo unitario de inversi贸n. A diferencia de trabajos anteriores, se usa el riesgo pa铆s de M茅xico en la tasa de descuento. Limitaciones: los costos relacionados con la transmisi贸n, distribuci贸n y tarifa de respaldo no est谩n incluidos. Concluyendo que los modelos estoc谩sticos brindan informaci贸n 煤til para la toma de decisiones al incorporar datos hist贸ricos y proyecciones de las principales variables que podr铆an afectar al LCOEE
