Contemporary formation indicators of free zones cities -Public Free zones models-
...Show More Authors

The free zone or the free economy cities are cities with classification and functional specificity, although the history of  the concept of these areas has been It dates back to distant eras, but the intellectual and philosophical construction with the support of intellectual approaches, the most important of which is globalization contributed to its rapid spread globally and taking a variety of forms and models. With the diversity of its formulas and objectives countries have competed in adopting the establishment of these areas, meanwhile The influence of related trends affected the contemporary formation of these sites. Therefore ,the research was directed focus on the importance of adopting a set of common indicators (collection between different formulas) these indicators ensure the formation of spatial formulas and urban structure for the model of cities and free zones with the influence of propositions and renewed proposals and connections that have a role in the process of creating an effective and influential structure within the location dimension and operational - activation within the functional dimension of these areas. the synthetic formula deduced according to the indicators represents the new phase of the free economic zones according to the

 

 perspective of contemporary vision. For thus , the research problem was identified by the weakness of existence of common indicators between the different forms of free zones indicated in accordance with contemporary trends to establish an urban structure that contributes solving new problems in hose areas . this is on  assumption that adopting of form of indicators contributes to providing the formation of a contemporary urban structure contributing to the construction of specialized cities models with special functional efficiency and effectiveness that developed to verification different goals , and multi changes in the best way.

Therefore , the important of research is evident because it is  providing measures in form of indicators for multiple levels that enable both planners , decision makers to crystallize the foundations to create an environment closer to the model. To achieve the hypothesis .The research adopts the descriptive analysis approach to deal with the theoretical foundations , while reviewing a number of selected experiment for models of various economic regions free zones to extract  the axes of the research indicators to present , Thus , researching a common level of standards for formulas of economic regions in building models that are more efficient and flexible to changes.

Implementation of a modified noise-free and noisy multistage quantum cryptography protocol using QISKIT
...Show More Authors

Classical cryptography systems exhibit major vulnerabilities because of the rapid development of quan tum computing algorithms and devices. These vulnerabilities were mitigated utilizing quantum key distribution (QKD), which is based on a quantum no-cloning algorithm that assures the safe generation and transmission of the encryption keys. A quantum computing platform, named Qiskit, was utilized by many recent researchers to analyze the security of several QKD protocols, such as BB84 and B92. In this paper, we demonstrate the simulation and implementation of a modified multistage QKD protocol by Qiskit. The simulation and implementation studies were based on the “local_qasm” simulator and the “FakeVigo” backend, respectively. T

Evaluation of some indicators of urbanization in the city of al-Qaim in the Iraqi province of Anbar
...Show More Authors

Urban Balance is one of the important indicators that leads to an assessment of the urbanization process in a particular country  , province or even a city that is multi-centered. By examining  the data related to Anba  province, it was found that the value of this indicator is equal to 0.96, which is less than the absolute one, and therefore the urbanization in the province is distributed collectively  

The development of a mathematical or statistical model for estimating urban growth is a complex process due to the overlap between indicators or variables that can be adopted to calculate estimate growth rates Al-Qaim city has been considered as an example to develop a statistical method by which changes

Class consciousness in the contemporary Marxist political thought (selected models)
...Show More Authors

Class consciousness represents its highest stage in the contemporary Marxist thought of Rosa Luxemburg and Antonio Gramsci, not just a reflection of reality, but rather a dialectical form through the reflection of consciousness on reality and its reproduction. The superiority over the infrastructure (historical materialism) promised the revolutionary class consciousness to be achieved spontaneously, and the seeds of a breakthrough are mass strikes, denying the role of the party to organize this awareness, limiting its role to the interconnection between classes, emphasizing the role of socialist democracy as a conscious vanguard for organizing spontaneity, struggle, and developing awareness during the revolutionary process and the leader
