We present a novel supervised learning approach for fault detection in subsurface geological slopes. Synthetic faulted slopes were generated using Delaunay triangulation via the Computational Geometry Algorithms Library (CGAL), enabling precise control over model parameters. A total of 24 features, encompassing local geometric attributes and neighborhood analyses, introduced classification. Support Vector Machine (SVM) classifier was employed, achieving high precision recall identifying...

Parsley (Petroselinum crispum L.) is a typical spice native to Mediterranean countries. It widely used enhance the flavor of different foods. On other hand there evidence for assumed diuretic effect parsley in folk medicine [1, 2]. In literature effects drying methods are described mainly on volatile components [3, 4]. The aim our study was include further analytical parameters order determine method unknown samples. At best we should be able identify blends air-dried an excess freeze-dried material.

ABSTRACT The rheological properties of different brands commercial tomato paste, sauce, puree and ketchup were estimated by imperfect squeezing flow viscosimetry using a wide plate shallow container. tests performed with polished grooved surfaces. In both, slip was prominent to such an extent that the equations for lubricated had be used calculation parameters. Despite its crudeness, procedure sensitive enough consistently monitor differences between products in terms apparent stress at...

ABSTRACT Agglomerated instant coffee particles were compressed individually with a TA‐XT2 Texture analyzer. Up to about 57% equilibrium relative humidity (ERH), the force‐displacement curves very jagged. The slopes of plots highest local force peaks vs deformation used as measure agglomerate stiffness. degree jaggedness original curves, brittleness measure, was quantified in terms an apparent fractal dimension using two algorithms. Stiffness and little affected by moisture at ERH levels...

ABSTRACT In squeezing flow viscometry the presence or absence of friction between specimen and plates has a dramatic effect on curve characteristics. It is therefore proposed that method can be used to test whether given surface, with particular rough finish, effective eliminate slip self‐lubricating food. The concept demonstrated experimental data commercial samples mayonnaise mustard, which were pressed pairs parallel polished metal in an imperfect array, their force height relationship...

Abstract. The study presents a novel approach for fault detection on geological terrains using supervised learning algorithm and careful variable selection. Synthetic faulted are generated Delaunay triangulation via the Computational Geometry Algorithms Library (CGAL) allowing adjustments of parameters. We introduce 24 variables, including local geometric features neighborhood analysis, classification. Support Vector Machine (SVM) is employed as classification algorithm, achieving high...

Abstract Mucilage of yellow mustard ( Sinapis alba L.) exhibits completely different rheological behaviour, depending on where it has been extracted from. Whereas mucilage isolated from intact seeds or separated brans acts like many hydrocolloids (e.g. increasing viscosity significantly at low concentrations) these and related properties (i. e. shear thinning behaviour) are lost, once processed. processed only raises slightly. Although the supernatant consists 3‐5% (dry matter), Newton ian...

Abstract Elite oregano clonal lines are being targeted by our laboratory for food preservative and nutraceutical applications. Oregano (Origanum vulgare) shoot clones inoculated with Pseudomonas sp. resulted in increased phenolics, reduced hyperhydricity, better tolerance to environmental stress adaptability when compared uninoculated control. In order confirm the qualitative biochemical observations related potential lignification cellulose build up, we have conducted mechanical load...
