In the present paper, discrete element method (DEM) is used to study wave propagation phenomenon in granular soils. The effect of factors such as coefficient of friction, frequency, normal stiffness and soil gradation on the wave velocity is studied. Using the wall motion based on the sinusoidal function is the method of loading used in this simulation, through which the pressure wave is transf...

Electron microscopic observations were made on lung tissue, broncho-pulmonary lavage fluid and sputum in 2 cases of pulmonary alveolar proteinosis. Diagnosis was established by open lung biopsy in both cases. In Case 1 the electron microscopic samples were obtained from the surgical specimen. In Case 2 an electron microscopic observation was made only on the lavage fluid and sputum. The alveola...

ABSTRACT Introduction: Granular cell tumors of the central nervous system are rare tumors. To date, eight cases arising from cranial nerves have been reported. Granular cell tumors have also been found arising from the neurohypophysis and its stalk. Due to their rarity and histological similarity to other central nervous system (CNS) tumors with a granular appearance, they often pose a diagnost...

in this paper, we introduce the concepts of norm and inner prod- uct on fuzzy linear spaces over fuzzy elds and discuss some fundamental properties.

congenital granular cell tumor (cgct) is a unique benign tumor of soft tissue in newborns, which usually occurs on the anterior alveolar mucosa of the jaws. it is 8 to 10 times more prevalent in females than males. we present a case report of a 3-month-old female infant, who had a solitary mass on the anterior mandibular alveolar ridge. the lesion, which was histologically a congenital granular...

the unique properties of air-cooled bainitic steels have been described. a series of mn containing air-cooled bainitic steels invented by authors is presented in this paper: including low carbon granular bainitic steels, low carbon grain-boundary allotriomorphic ferrite/granular bainite duplex steels, medium and medium high carbon bainite/martensite duplex steel, and low carbon carbide free bai...

This paper studies a bidisperse granular mixture consisting of two species of stainless steel spheres in a vertically vibrated compartmentalized container. The experiments show that with proper vibration acceleration, the granular clock stops when horizontal segregation of the large spheres residing in the far end from the barrier wall occurs. When the segregation is broken, the granular clock ...

As an emerging conceptual and computing paradigm of information processing, granular computing has received much attention recently. Many models and methods of granular computing have been proposed and studied. Among them was the granular computing model using information tables. In this paper, we shall demonstrate the application of this granular computing model for the study of a specific dat...

Granular cell tumor is rare and accounts for approximately 0.5% of all soft tissue tumors. The malignant granular cell tumor, especially cutaneous malignant granular cell tumor is extremely rare. The present case is the first patient of primary cutaneous malignant granular cell tumor reported from China in English. A review of the literature is performed, and the presentation, position, patholo...
