The minimum weight vertex cover problem (MWVCP) is a fundamental combinatorial optimization read more problem with various real-world applications.The MWVCP seeks a vertex cover of an undirected graph such that the sum of the weights of the selected vertices is as small as possible.In this paper, we present an effective algorithm to solve the MWVCP

In order to meet the demands of the European market, a new articulated car body structure for EMUs has been developed in compliance with the requirements of the European technical specifications for interoperability (TSIs) and incorporating the installation requirements of the articulated bogies.By optimizing the force flow transfer path and adopti

Meditation programs continue to proliferate in the modern world, with increasing participation from scientists and many others who seek to improve physical, mental, relational, and social flourishing.In developing such programs, the meditation practices have been adapted to meet the needs of modern cultures.However, through that adaptation, importa

Variational mode decomposition (VMD) method has been widely used in the field of signal processing with significant advantages over other decomposition methods in eliminating modal aliasing and noise robustness.The number (usually denoted by K) of intrinsic mode function (IMF) has a great influence on decomposition results.When dealing with signals
