The Gardner equation is an extension of the Korteweg–de Vries (KdV) equation. It exhibits basically the same properties as the classical KdV, but extends its range of validity to a wider interval of the parameters of the internal wave motion for a given environment. In this paper, we derive...

In this paper, we derive three conservation laws and three invariants of motion for the generalized Gardner equation. These conserved quantities for internal waves are the momentum, energy, and Hamiltonian. The approach used for the derivation of these conservation laws and their associated...

Entrepreneurship and new technologies are the moving forces for growth and change the economies. Experience of the European countries has shown that countries that support their entrepreneurs have grown and prospered over the last 15 years, while nations that have placed barriers to the growth...

The global financial and economic crisis is felt in almost all the companies that operate on the European financial and insurance markets. The European insurance and re-insurance industry would register a significant decrease of the investments and a redu

The impact of the crisis on Europe comes from both direct and indirect channels. The direct effects have been felt mostly through the financial sector. For example, stock market volatility has increased since the onset of the crisis and wealth losses have been observed in the major stock...

A variety of factors led or contributed to the current financial crisis, including loose monetary policy; excessive financial market liquidity, leverage and maturity mismatch; weak risk management and underwriting standards; and poor incentives and regulatory gaps in some important segments of...

The scientific research is very careful supervised to national level, institutional and individual, products and services, a mean of preparing human resources highly qualified and as a source of prestige for countries, institutions and persons. Banks and generally the whole banking system must...
