This paper discusses risk modeling and risk management in information and communications technology (ICT) systems for which the attack impact distribution is heavy tailed (e.g., power law distribution) and the average risk is unbounded. Systems with these properties include billing infrastructures used to charge customers for services they access. Attacks against billing infrastructures can be ...

The effect of magnetic field on the liquid-liquid equilibrium of two ternary systems (water + acetic acid + butyl acetate and water + acetic acid + dimethyl succinate) at 298.15 K under atmospheric pressure was investigated. The results obtained show that the strength of the magnetic field (0.02 T) affects the solubility of acetic acid in the used organic solvents. Distribution coefficients and...

abstract the main purpose of this study was to determine farmers’ satisfaction towards pressurized irrigation systems in kermanshah province. this study used a mixed method design with descriptive correlation emphasis. a researcher made questionnaire was used to collect data. a random sample of 274 farmers who have been equipped with pressurized irrigation systems during the last three years pa...

A fundamental obstacle to successful dissemination and implementation of evidence-based public health programs is the near-total absence of systems and infrastructure for marketing and distribution. We describe the functions of a marketing and distribution system, and we explain how it would help move effective public health programs from research to practice. Then we critically evaluate the 4 ...

one of the consequences of poor management and operation of irrigation systems, poor water delivery and distribution channels and divisions and consequently improper distribution of water level downstream. the study of simulation and performance evaluation software using hydrodynamic sobek varamin irrigation is done. in order to evaluate the network performance and compare the results of simula...

the methods, the technology, the production patterns, the equipment, the capacity of the domestic infrastructure of each country, the mechanism of market capacity, market chains, releasing and distribution channels of agricultural and food product, purchasing patterns, and food consuming of consumers affect on the wastes of food products. regardless of the level of economic and social developme...

Ensuring reliable access to clean and affordable water is one of the greatest global challenges of this century. As the world's population increases, water pollution becomes more complex and difficult to remove, and global climate change threatens to exacerbate water scarcity in many areas, the magnitude of this challenge is rapidly increasing. Wastewater reuse is becoming a common necessity, e...
