Audio compression is used everywhere – largely due to the rise of the internet, computers, and embedded systems. Since original, uncompressed digital recordings are very large in size, efficient ways are needed to compress large audio signals into small, high-quality, convenient formats. While lossy audio formats, like MP3, are widely popular in many everyday applications, lossless formats are ...

The stability assessment of the complex salt cavities, placed inside the salt rock mass, represents a real scientific and technical challenge for any researcher focused on the geomechanics field. The purpose of this paper is 3D stability modelling for the Praid salt mines, Romania, taking into account the salt cavities mining dynamics and also the intrinsic parameters’ effect over the salt rock...

In this study, we investigate the effects of CO2 laser polishing on microscopic structures fabricated by femtosecond laser assisted carving (FLAC). FLAC is the peripheral laser irradiation of 2.5D structures suitable for low repetition rate lasers and is first used to define the microwell structures in fused silica followed by chemical etching. Subsequently, the bottom surface of patterned micr...

The research on the dynamic response and influencing factors of shield tunnel lining under earthquake demonstrates significant engineering value in guiding design antiseismic tunnels. In this paper, a nonlinear finite element model soil-tunnel interaction is established based FLAC difference software, then Mohr–Coulomb elastoplastic plastic damage are used to simulate characteristics soil tunne...

Background: Vibrio are the main pathogenic bacteria in aquaculture. The flagellin protein C (FlaC) of Vibrio alginolyticus has good immunogenicity and the prospect of potential application in a vaccine. Objectives: We aimed to evaluate the immunogenicity, protective immunity, and prokaryotic expression fermentation of V. alginolyticu...

Geosynthetics have proved to be suitable for reinforced soil retaining walls. Based on the increasing uses of geosynthetic reinforced soil systems in the regions, which bear frequent earthquakes, the study of dynamic behavior of structures seems necessary. Determining the reinforcement forces is; therefore, one of the most important and main points of discussions in designing retaining walls, b...
