Viuhka is a compositional tool situated in PWGL. The system has been recently adapted in order to enhance our notation package. This paper contains a new notational short-hand, called macro-note, that can be used to realize short musical segments that have their lifespan within a macro-note. The system allows to generate various ornaments in the traditional sense, such as tremolos, trills, and ...

As silicon photovoltaics evolve towards thin-wafer technologies, efficient optical absorption for the near-infrared wavelengths has become particularly challenging. In this work, we present a solution that employs combined micro- and nano-scale surface textures to increase light harvesting in the near-infrared for crystalline silicon photovoltaics, and discuss the associated antireflection and ...

Carbonaceous mesophases are liquid crystalline precursor materials that can be spun into high performance carbon fibers using the conventional melt spinning process. Carbon fiber property optimization requires a better understanding of the principles that control the structure development during the fiber formation processes and the rheological processing properties. This work presents the elas...

The Eocene-Oligocene Sarbisheh volcanic complex is a part of the Lut-Sistan Zone that outcrops in eastern Iran. In the east of this complex, three groups of volcanic rocks (i.e., andesite, dacite, and rhyolite) exist. Plagioclase as the main mineral of these rocks is found with varying micro-textures. Based on a changing trend in the concentration of anorthite, the developed micro-textures (coa...

In this paper we propose and examine non–parametric statistical tests to define similarity and homogeneity measures for textures. The statistical tests are applied to the coefficients of images filtered by a multi–scale Gabor filter bank. We will demonstrate that these similarity measures are useful for both, texture based image retrieval and for unsupervised texture segmentation, and hence off...

This contribution is concerned with texture synthesis by example, the process of generating new texture images from a given sample. The Random Phase Noise algorithm presented here synthesizes a texture from an original image by simply randomizing its Fourier phase. It is able to reproduce textures which are characterized by their Fourier modulus, namely the random phase textures (or micro-textu...

Diamond-coated tools often fail due to coating graphitization and delamination caused by poor adhesion, large contact stress, thermochemical reactions. To address these issues, this research utilized a combination of micro-nano double-layer diamond coating, WS2 micro-textures. The inhibits the through transfer film mechanism, while micro-textures nanocrystalline store WS2, resulting in prolonge...

Growth characteristics of human connective tissue progenitor (CTP) cells were investigated on smooth and textured substrates, which were produced using MEMS (microelectromechanical systems) fabrication technology. Human bone marrow derived cells were cultured for 9 days under conditions promoting osteoblastic differentiation on polydimethylsiloxane (PDMS) substrates comprising smooth (non-patte...

Metal machining is one of the most important manufacturing processes in today’s production sector. The tools used have been developed over years to improve their performance, by reducing cutting forces, friction coefficient, and heat generated during process. Several cooling systems emerged as an effective way remove excessive from chip-tool contact region. In recent years, introduction nano mi...
