In this paper two similar models for the maintenance of a production-inventory system are considered. In both models, an input generating installation supplies a buffer with a raw material and a production unit pulls the raw material from the buffer. The installation in the first model and the production unit in the second model deteriorate stochastically over time and the problem of their opti...
The subject of this article is determining the oil optimal production path in one of the Iranian oil and gas brown field in Persian gulf, while the development of the field performed under the buyback contractual framework. In this research we have optimized a dynamic equation using numerically Bellman equation in Matlab program .We have considered different and possible oil price projections a...
This paper investigates the optimal fiscal policy, pertaining to government spending, considering different productivity of public services in production function and its impact on the optimal tax rate, the optimal rate of government spending, and optimal economic growth rate. Using the VECM model for Iranian economy over 48 years, results show while the current expenditure has a positive and s...
We study the development of conjunctive keyword searchable scheme which enables one to search encrypted documents by using more than one keyword. The notion of conjunctive keyword searching was presented by Golle et al. in 2004. However, their security model was constructed in a symmetric-key setting which is not applicable for the overall applications in the reality. So Park et al. extended Go...
In this paper we present several proofs on the extension of M. Riesz fractional integration and di¤erentiation to the contexts of spaces of homogeneous type and measure metric spaces with non-doubling measures. 1. Introduction, some de nitions, and a basic lemma Professor M. Ash asked me to write a survey article on some of the results that Stephen Vági and I obtained in the nineties on fractio...
This paper presents a system of systems (SoS) Biofuel model considering the interdependency among the systems involved in biofuel development, including biofuel refinery location, transportation infrastructure, agricultural production and markets, environment, and social communities. The model provides the optimal infrastructure development and land-use allocation for biofuel production in a re...
Viruses reproduce by multiplying within host cells. The reproductive fitness of a virus is proportional to the number of offspring it can produce during the lifetime of the cell it infects. If viral production rates are independent of cell death rate, then one expects natural selection will favor viruses that maximize their production rates. However, if increases in the viral production rate le...
This work investigates the nature of technological development and the viability of applying an evolutionary approach to the early development of iron production in Sri Lanka. The main objective of this paper is to use modern techniques in the fields of Physics and Engineering to investigate the wind-driven furnace used in early iron and steel producing industry dating to 300 B.C. In order to s...
e-Government is already in its second decade. Prerequisite for further development and adaptation to new realities is the optimal management of administrative information and knowledge production by those involved, i.e. the public sector, citizens and businesses. Nowadays, the amount of information displayed or distributed on the Internet has reached enormous dimensions, resulting in serious di...
