An analysis of combined cyclic heat treatment performance
Journal of Materials Processing Technology, 2004The strengthening of AISI 4140 steel by cyclic heat treatment has been investigated. The applied cyclic heat treatment was consisted of both, temperature cycling with diffusional transformation and double quenching with diffusionless transformation.

Performance of organic coatings upon cyclic mechanical load
Progress in Organic Coatings, 2020Abstract A number of engineering structures fail due to the fatigue damage resulting from cyclic mechanical stress. However, as far as organic coatings are concerned this degradation factor remains underestimated. In the paper the authors propose a methodology combining global electrochemical impedance spectroscopy and local atomic force microscopy ...

Cyclic Change of Server's Performance: Impacts and Applications
IEEE Transactions on Automatic Control, 2014This paper studies a stochastic system where the performance of the server changes stochastically and cyclically. We first investigate the performance measures of the system, including the queue length and the overall cost. In particular, we derive an exact expression for the expected length of the renewal cycle, and present closed matrix forms for the

Lateral Cyclic Performance of Hybrid Fabricated Beam‐Columns
ce/papers, 2021AbstractIn this paper, a high‐capacity fabricated hollow section is proposed as a lightweight replacement for concrete‐filled composite members which are commonly used as beam‐columns in seismic zones. The lateral cyclic performance of the fabricated hollow beam‐column comprising of mild steel plates (grade 250) and high strength steel (HSS) tubes ...

Performance of carbide composites for cyclic loading applications
International Journal of Materials and Product Technology, 2007The present study attempts to give deeper insight into the surface damage process of carbide composites such as WC hardmetals and TiC-based cermets in the blanking of sheet metals (in cyclic loading conditions). In addition, it focuses on the relationships between the blanking performance of composites on the one hand and the structure-composition and ...

Improved Performance and Cost in Cyclic Production Systems
Journal of Cost Analysis and Parametrics, 2009Abstract Increased competition has forced companies to focus more attention on producing at a globally competitive cost. To cope, firms focus on flexible manufacturing, integration, and automation to help ensure that firm-specific manufacturing environments remain competitive.

Performance of corroded bridge piers under cyclic loading
Proceedings of the Institution of Civil Engineers - Bridge Engineering, 2017The presence of chloride ions causes reinforced-concrete (RC) bridge piers in a corrosive environment to suffer from different degrees of corrosion damage. Investigation of the seismic performance of corroded RC bridge piers using cyclic loading is therefore of great value.

Performance analysis and optimization of cyclic production lines
IIE Transactions, 2002In this paper, a model of a cyclic production line is introduced and analyzed. Using Taylor series expansion, we present an approximation method for the analysis of the average steady-state throughput of cyclic production lines with unreliable machines, finite buffers and a fixed number of pallets circulating in the line. Using the approximation method,

Measuring Cyclical Sensitivity in State Performance: 1969-1984
1987The cyclical performance of state economies is a topic of concern to state planners which is likely to be of increasing importance. The continuing effort of the federal government to shift the budget responsibility for a growing number of programs to the state level has created a new urgency to the importance of understanding state cycles.

Performance of Cyclic Delay Diversity in Ricean Channels
2007Cyclic delay diversity (CDD) provides additional diversity in Rayleigh fading channels, and therefore, improves system performance. For line-of-sight (LOS) propagation, e.g. the additive white Gaussian noise channel, the implementation of CDD yields to a performance loss.
