This paper reviews a cyclic scheduling model of repetitive manufacturing environments consisting of exible machines and multi-stage jobs. We explicitly model two system performance measures, throughput and ow time, while incorporating variability arising from uncertainty in operation processing times. We present an iterative approximation scheme to estimate the two moment behavior of our perfor...

This paper presents a sensitivity analysis of filter bank multicarrier (FBMC) systems to carrier frequency offset (CFO) and timing offset. Although the emphasis of the paper is on the class of FBMC systems that are based on offset quadrature amplitude modulation (OQAM), the developed results are found applicable to cosine modulated-based FBMC systems as well. We assume that coarse CFO and timin...

The spatial-dependent-propagation (SDP) model with a nearby source works well to reproduce the coevolving features of both cosmic-ray (CR)-nuclei spectra and anisotropy. However, it is known that Sun actually deviating from galactic disk. This will lead dominating anisotropy in direction perpendicular disk, which discrepant current observations. Thus, necessary further investigate effect solar ...

in order to lighten the prestressed concrete solid members, nowadays, it is possible to make use of the advantage of hpc (fc'>60 mpa) as well as replacing the solid section with a psc thin-walled section for certain members such as circular and box columns. using the strength theory of aci, a numerical procedure along with a computer program was developed for the analysis of such sections ...

Measuring reflection amplitude versus offset (AVO) has proved to be effective in reservoir characterization. Experience shows that AVO inversion methods based on amplitude-preserved prestack migration typically provides a more accurate lithology estimate than NMO-based AVO analysis. However, some artifacts may be introduced into the migration section due to an undersampled acquisition geometry,...

The porosity distribution law of overlying strata in the goaf has an important guiding role distinguishing hidden disaster-causing factors goaf, such as gas enrichment area and spontaneous combustion area. Existing research is concentrated on a single working face (GSWF), adjacent (GAWF) must be different from that GSWF. By selecting Longshan Coal Mine engineering background applying theoretica...

Synchronization, which is composed of estimation and control, is one of the most important functionalities of the receiver. It must be first performed by the receiver when receiving information data. In an OFDM system, synchronization can be divided into three different parts—carrier frequency offset synchronization, DFT window timing synchronization, and subcarrier recovery. As shown in Sectio...
