The present paper provides a semi-analytical solution to obtain the displacements and stresses in a functionally graded material (FGM) rotating thick cylindrical shell with clamped ends under non-uniform pressure. Material properties of cylinder are assumed to change along the axial direction according to a power law form. It is also assumed that the Poisson’s ratio is constant. Given the exist...
Graphene with ultrahigh intrinsic strength and excellent thermal physical properties has the potential to be used as the reinforcement of many kinds of composites. Here, we show that very high tensile strength can be obtained in the copper matrix composite reinforced by reduced graphene oxide (RGO) when micro-layered structure is achieved. RGO-Cu powder with micro-layered structure is fabricate...
Resource allocation approaches play a very important role in improving the performance of a communication system. Load matrix (LM) [3] is a resource allocation approach used in single carrier mobile communication systems in a multi-cell scenario to reduce the interference (both inter-cell and intra –cell) to increase the system throughput decrease the packet delay. In this paper a resource allo...
introduction lead-based shields are the most widely used attenuators in x-ray and gamma ray fields. the heavy weight, toxicity and corrosion of lead have led researchers towards the development of non-lead shields. materials and methods the purpose of this study was to design multi-layered shields for protection against x-rays and gamma rays in diagnostic radiology and nuclear medicine. in this...
Soft X-rays excite the inner shells of materials more efficiently than any other form light. The investigation synchrotron radiation (SR) processes using inner-shell excitation requires beamline to supply a single-color and high-photon-flux light in soft X-ray region. A new integrated computing multi-layered-mirror (MLM) monochromator was installed at 07A (BL07A) NewSUBARU, which has 3 m undula...
generally, alluvial basins of arid and semiarid zones are the places with excessive groundwater withdrawal, and also they have a high potential for land subsidence. excessive groundwater withdrawals have caused severe land subsidence in tehran, iran. at present, the maximum land subsidence rate is 36 cm/year, covering an area of nearly 530 km2. in the 2000s, as a result of economic and populati...
ABSTRACT The mixed linear model (MLM) is an advanced statistical technique applicable to many fields of science. The multivariate MLM can be used to model longitudinal data, such as repeated ratings of disease resistance taken across time. In this study, using an example data set from a multi-environment trial of northern leaf blight disease on 290 maize lines with diverse levels of resistanc...
The max-log-map (MLM) receiver is an approximated version of the well-known, Bahl-Cocke-Jelinek-Raviv (BCJR) algorithm. The MLM algorithm is attractive due to its implementation simplicity. In practice, sliding-window implementations are preferred; these practical implementations consider truncated signaling neighborhoods around each transmission time instant. In this paper, we consider the bin...
Design of electromagnetic (EM) actuators often involves solving a magnetic field problem. This paper presents an adaptive meshless method (MLM) that inherits many advantages of the finite-element method (FEM) but needs no explicit mesh structure for design of EM actuators. Specifically, the paper offers a technique to estimate the distribution of numerical errors and a scheme that automatically...
