Interference and Deployment Issues for Cognitive Radio Systems in Shadowing Environments [PDF]

open access: yes, 2009
In this paper we describe a model for calculating the aggregate interference encountered by primary receivers in the presence of randomly placed cognitive radios (CRs). We show that incorporating the impact of distance attenuation and lognormal fading on

Experiments on flexural behavior of the prefabricated RAC and NWC composite slab

open access: yesAin Shams Engineering Journal, 2022
The development of prefabricated buildings is a long-term industrial policy in China. In the prefabricated frame structure, the slab is one of the critical components. However, two kinds of famous prefabricated slabs in China need the template system and

Effect of porosity on physical properties of lightweight cement composite with foamed glass aggregate

open access: yesITM Web of Conferences, 2017
This paper reports on a study of physical properties of lightweight cement composite. We investigate the possibility of replacing traditional aggregate with Granulated Ash Aggregate (GAA) and above all with Granulated Expanded Glass Aggregate (GEGA). For

Explainable Composition of Aggregated Assistants

open access: yes, 2020
A new design of an AI assistant that has become increasingly popular is that of an "aggregated assistant" -- realized as an orchestrated composition of several individual skills or agents that can each perform atomic tasks. In this paper, we will talk about the role of planning in the automated composition of such assistants and explore how concepts in

Mind and Body [PDF]

open access: yes, 2015
This chapter discusses Gottfried Wilhelm Leibniz’s philosophical reflections on mind and body. It first considers Leibniz’s distinction between substance and aggregate, referring to the former as a being that must have true unity (what he calls unum per ...

New Lime-Based Hybrid Composite of Sugarcane Bagasse and Hemp as Aggregates

open access: yesResources, 2023
Bio-based materials help reduce the consumption of non-renewable resources, contributing to the development of sustainable construction. Industrial Hemp Concrete (IHC), which uses hemp stalk (HS) as an aggregate and a lime-based binder, is a bio-based ...

Some considerations on aggregate sample supports for soil inventory and monitoring [PDF]

open access: yes, 2012
Soil monitoring and inventory require a sampling strategy. One component of this strategy is the support of the basic soil observation: the size and shape of the volume of material that is collected and then analysed to return a single soil datum.

Numerical Simulation of Pervious Concrete Based on Random Pore Model

open access: yesAdvances in Civil Engineering, 2020
The features of the pores in pervious concrete have a great influence on the mechanical property of the pervious concrete. In this study, a finite element model (FEM) with random pores has been used to simulate the mechanical characteristics of pervious ...
