Despite the growth in Iran’s petrochemical production, most of the plants are concentrated upstream; although the government has made various interventions to promote industrial development. The literature review shows that government intervention is necessary to solve market failures, especially in developing countries; but it should be tailored to the specific context and especially the distribution of the power. Most experts believe that the cause of the above phenomenon is feedstock rent and the reason for its continuation is the political influence of petrochemical companies. While not rejecting this view, we try to provide policy recommendations by looking more closely at the issue and... 

As accelerators develop, literature about their distinctive characteristics and functions grow.

One of the most famous criteria to measure the optimality of the election result in the metric space is the amount of distortion. In this framework, the cost of choosing each candidate is considered equal to the total distance of the community members from that candidate. With this definition, the candidate who has the lowest selection cost among all the candidates is called the optimal candidate. The amount of distortion for an electoral mechanism is equal to the maximum amount of the cost of selecting the selected candidate divided by the cost of selecting the desired candidate. It turns out that no deterministic voting mechanism can guarantee a distortion value better than 3. Various... 

Neither state planning nor economic liberalization has been the answer for developing countries to escape from the middle-income trap, mainly due to presence of institutional voids and due to the governance of hindering institutions. Therefore, we need another explanation for how of the development, which must include how institutions change and how new institutions and new institutional fields emerge. Developing countries are full of institutional voids and the governance of hindering institutions. Therefore, the process of economic development in these countries, is beyond the power of market and state, and needs agency. Responding to the recent call by the literature for doing more... 

In this thesis, three different mathematical models named Markov Reward Model (MRM), Stochastic Reward Net (SRN) and Stochastic Activity Network (SAN) are used to model and evaluate the performability of grid computing environments consisting of many grid resources. The proposed models consider the arriving and servicing process of grid tasks inside a resource together with the failure-repair behavior of processors of the resource. Since the proposed MRM cannot be extended to model a grid environment with some realistic assumptions, we switch to use SRNs in modeling a single grid resource with more number of processors. Although the proposed SRN models for a single grid resource can...

Delay-tolerant networks refer to the networks that lack stable end-to-end paths due to the high mobility of nodes. In order to tackle the intermittent connections, nodes of delay-tolerant networks store the data packets and carry them. Nodes forward data packets according to routing protocols once they enter each other's communication range. In order to increase the probability of delivery, several or many copies of a packet can be disseminated in the network. Over the past years, various routing protocols have been proposed for delay-tolerant networks. These protocols differ from each other in the number of copies that are disseminated in the network or the information used to make routing...
