The aim of present study is to investigate the effect of various parameters such as length, thickness, density, shear modulus of the core and Young modulus of skins for various boundary conditions:  clamped-free and simply supported. By applying the model of Khalili et al for frees vibration analysis of sandwich beams by using finite element methods. Where, the core density is taken on consider...

In wireless communications, knowledge of the node-tonode distance is essential in tasks such as system configuration, protocol design, and performance analysis. In this paper, we empirically describe the distance density between nodes in nonoverlapping networks under the assumptions of circular coverage area and uniform node distribution. In general, this problem has no closed-form solution. He...

Infrastructure-based indoor geolocation systems utilizing a regular grid arrangement of sensors are being investigated for many applications in indoor wireless networks. One of the factors affecting the Quality of Estimation (i.e. location estimation accuracy) of these systems is node density. In this dissertation we study the effects of node density on indoor geolocation systems based on time ...

Lymph node density (LND)—the proportion of positive nodes among the total number resected nodes—has emerged as a reliable prognostic factor in solid tumors. This study aims to assess importance LND lingual squamous cell carcinoma (LSCC) and its involvement. A retrospective longitudinal with 62 patients was performed. All were diagnosed LSCC submitted for tumor resection neck dissection. Patient...
