granular cell tumors are rare neoplasms of uncertain histogenesis but with a typical histologic appearance composed of cells with characteristic granular cytoplasm. these tumors occur most often in adults as an asymptomatic solitary papule or nodule. multiple granular cell tumors are rare, especially in children and teenagers. we represent a case of multiple granular cell tumors in a 19-year-ol...

Knowledge distance is used to measure the difference between granular spaces, which an uncertainty with strong distinguishing ability in a rough set. However, current knowledge failed take relative spaces into account under given perspective of uncertain concepts. To solve this problem, paper studies intuitionistic fuzzy concept (IFC). Firstly, micro-knowledge (md) based on information entropy ...

Pulmonary alveolar proteinosis is a rare disease of the lung in which excessive thick granular phospholipoproteinaceous material accumulates within the air spaces. Many patients with this disease suffer from progressive dyspnea and cough that at times is accompanied by worsening hypoxia. At present, the only effective treatment is bronchoalveolar lavage, first described by Ramirez in 1963 (1). ...

Silos are structures that are used for storing different types of granular material. Dynamic behavior of silos under seismic loads is very complex. In this paper seismic behavior of steel silos with different height to diameter ratios is investigated by considering granular material-structure interaction using ABAQUS finite element package. Silo wall is modeled by shell elements and its behavio...

Recent advances in vision-based navigation and exploration have shown impressive capabilities photorealistic indoor environments. However, these methods still struggle with long-horizon tasks require large amounts of data to generalize unseen In this work, we present a novel reinforcement learning approach for multi-object search that combines short-term long-term reasoning single model while a...

There has been a resurgence in interest the off-grid city Global South, and on how it functions as collection of places, lived spaces, dynamic infrastructural configurations. As scholars practitioners working South African urban context, we identify four areas for further elaboration research: 1.) redefining academic practical understandings “grid”, ultimately moving to rethink its meaning city...

The concepts of approximations in granular computing (GrC) vs. rough set theory (RS) are examined. Examples are constructed to contrast their differences in the Global GrC Model (2nd GrC Model), which, in pre-GrC term, is called partial coverings. Mathematically speaking, RS-approximations are “sub-base” based, while GrC-approximations are “base” based, where “sub-base” and “base” are two conce...

Operations between two granules and inclusion measure are two important issues in granular computing. Two operations between two granules, named join operation and meet operation, are formed to realize the transformation between granule spaces with different granularities, and the fuzzy inclusion measure is induced by the aforementioned operations. The granule set, operations, and fuzzy inclusi...

In Ludwig Danzer’s Habilitatiionsschrift [L. Danzer, Endliche Punktmengen auf der 2-Sphäre mit möglichst grossem minimalabstand, Habilitationsschrift, Göttingen, 1963] he initiated a study of the local nature of the packings from the point of view of whether their density can be increased by a small perturbation of the packing configuration. This is an abbreviated biased introduction to the the...
