This paper presents a practical and efficient method to solve large-scale nonlinear equations. The global convergence of this new trust region algorithm is verified. The algorithm is then used to solve the nonlinear equations arising in an Expanded Lagrangian Function (ELF). Numerical results for the implementation of some large-scale problems indicate that the algorithm is efficient for these ...

Research background: Unemployment presents one of the most important macroeconomic indicators, which is basic economic and social problem number countries fights with this problem. presently considered as serious V4 have big to employ people. Young people, are unemployed, show find job in time school termination, confirming that they would be willing migrate due job. Job Offices has therefore a...

historically, central asia and the caucasus has been the source of important developments in the regional and global level. the whole geopolitical theories in the 20th and 21st century paid special attention to this area. geopolitical status of the region has posed challenges for residents and even neighbors of the region. these challenges can be described as the divergence factors. therefore, ...

background and purpose: more than a third of the world’s population lack access to essential medicines, despite the presence of several international agreements that proclaim health as a human right. corruption, in its many forms, such as bribery and embezzlement, causes several detrimental effects on the health sector and access to medicines including economic, health, and government image and...

the goal of this study was to estimate the sensitivity of reference evapotranspiration (et0) to changes in meteorological parameters in the caspian region. long-term meteorological data (1961-2008) were obtained from three synoptic meteorological stations. the region was primarily classified into three climatic zones, based on de martonne climate classification. the penman–monteith equation was...
