In this paper, we proposed an improved SEW/REW decomposition method with pitch-dependent phase generation and a noble VBR scheme for bit rate reduction in waveform interpolative coders. The proposed decomposition is performed in the magnitude domain to reduce spectral distortions. The phase of the characteristic waveforms is generated after classifying the signal into silence, unvoiced and voic...

The literature on the estimation of treatment effects has matured in economics. The potential outcomes framework guides the estimation of the causal effect of economic choices or policy interventions. The application of methods from the treatment effects literature has spread from the analysis of the effects of labor market programs and the wage return to education to other areas in economics. ...

The huge amount of information available on the Web has attracted many research efforts into developing wrappers that extract data from webpages. However, as most of the systems for generating wrappers focus on extracting data at page-level, data extraction at site-level remains a manual or semiautomatic process. In this paper, we study the problem of extracting website skeleton, i.e. extractin...

The surgical treatment for thoracic and thoraco-abdominal aortic aneurysms still remains a challenge for the surgeon, as it can be complicated by paraplegia. Several techniques were developed in order to decrease the risk of paraplegia. We describe a surgical variation of the 'clamp and sew' technique, named 'Quick simple clamping' technique, that we adopted starting in 1995. In our experience,...

Since about 2010, big data analysis has drastically changed the landscape of information management by becoming a central topic in academic literature several fields. Despite significant contribution family firms to economic fabric worldwide and their unique decision-making processes, there is lack research investigating family-owned businesses. To address this gap, article draws on socioemotio...

The amount of residual lignin and hemicelluloses in softwood fibers was systematically varied by SO2-ethanol-water fractionation for integrated biorefinery with nanomaterial and biofuel production. On the basis of their low energy demand in mechanical processing, the fibers were deconstructed to lignocellulose nanofibrils (LCNF) and used as substrate for bioconversion. The effect of LCNF compos...

Internet memes are one of the latest evolutions “leaflet” propaganda and an effective tool in arsenal digital persuasion. In past such items were dropped from planes, now they find their way into social media across multiple platforms territory is global. can be used to target specific groups help build solidify tribal bonds. Due ease creation, ability constantly reaffirm axiomatic ideas, have ...

This paper takes the tomb murals as research object, and realizes development of costume patterns Tang 3D simulation restoration costumes through interactive clothing pattern-making technology virtual technology. Firstly, garment model is constructed in environment according to outline Dynasty mural costume. Then, structural curves are drawn on characteristics style, surface expanded surrounded...
