Load spectrum for utility trenches in the footway
Proceedings of the Institution of Civil Engineers - Municipal Engineer, 2003Local authorities are concerned about the adoption of cable television networks after they reach two years of age. Concerns have been raised about the shallow burial depth (250 mm to the crown for ducts in footways), the longevity of the reinstatement, and the possibility of future damage to footways under vehicle loading. The aim of this research was

In general, the load spectrum is too large and extensive to test the lifetime of a component. To hasten the testing time and to reduce costs, the load spectrum should be accelerated so that its much shorter testing time is equivalent to the real lifetime for the load spectrum. The equivalent load spectrum is called the accelerated load spectrum.

Spectrum Loading Type Dynamic Spectrum Allocation Technique for Cognitive Radio Systems
2007 2nd International Conference on Cognitive Radio Oriented Wireless Networks and Communications, 2007This paper proposes a spectrum loading type dynamic spectrum control technique for broadband cognitive radio systems. In the proposed scheme, based on the detection of available spot-wise spectra, discrete spectrum components of a framed symbol sequence are mapped onto the spot-wise spectra.

Load-Balancing Spectrum Decision for Cognitive Radio Networks
IEEE Journal on Selected Areas in Communications, 2011In this paper, we present an analytical framework to design system parameters for load-balancing multiuser spectrum decision schemes in cognitive radio (CR) networks. Unlike the non-load-balancing methods that multiple secondary users may contend for the same channel, the considered load-balancing schemes can distribute the traffic loads of secondary ...

Shearer Load Identification of the Load Spectrum of the Pick Based on Chaotic Characteristics
Advanced Materials Research, 2011Due to shearer drum suffers a very complex load，the traditional theoretical algorithm of cutting resistance is difficult to satisfy the analysis and design of shearer, and the load features of various conditions is hard to obtain with experimental methods.

Effects on Lifetime under Spectrum Loading*
Materials Testing, 2010Abstract Most components and structures are submitted to load-time histories with variable amplitudes during their service life. Their safe design, in the context of weight reduction requirements, demands detailed and deep knowledge about the effects of spectrum shape, blocked or random sequences, material response, cumulative damage ...

Loading spectrum for highway bridges and damage criteria for cumulative loading.
2009Bridges are presently designed to withstand the bending moments and shear forces produced by a standard design truck such as AASHO H2O-S16. However, bridges are subjected to a large number of loads of different magnitude randomly ordered with respect to time.
