Multistage fluid activities and hydrocarbon accumulation processes have occurred in the Dengying Formation of Sichuan Basin during its long geological history. Petrography cathodoluminescence observations; situ microanalysis rare earth elements, carbon, oxygen, strontium isotopes; inclusion microthermometric experiments; laser Raman burial history; thermal generation history simulation been app...

Monitoring the reliability of products in both the manufacturing and service processes is of main concern in today’s competitive market. To this end, statistical process control has been widely used to control the reliability-related quality variables. The so-far surveillance schemes have addressed processes with independent quality characteristics. In multistage processes, however, the cascade...

| In this paper we present the multistage oo-line method, a new and rather natural way to model oo-line packet routing problems, which reduces the problem of oo-line packet routing to that of nding edge disjoint paths on a multistage graph. The multistage oo-line method can model any kind of routing pattern on any graph and can incorporate the size of the maximum queue allowed in any processor....

A multistage cancer model that describes the putative rate-limiting steps in carcinogenesis is developed and used to investigate the potential impact on cumulative lung cancer incidence of the hormesis mechanisms suggested by Feinendegen and Pollycove. In the model, radiation and endogenous processes damage the DNA of target cells in the lung. Some fraction of the misrepaired or unrepaired DNA ...

Currently, the threshold T must be entered manually, based on given or estimated values for the SNR of the degraded image. Future work will look at ways to automate this process. Also, we found that at very low SNR, the AMP median filter introduces a few speckles into the restored image. We suspect that this may be due to incorrect adaption in regions of exceptionally high noise levels. Further...

An exact transformed culling method for any number of traits or stages of selection with explicit solution for multistage selection is described in this paper. This procedure does not need numerical integration and is suitable for obtaining either desired genetic gains for a variable proportion selected or optimum aggregate breeding value for a fixed total proportion selected. The procedure has...

In this paper we present the multistage off-line method, a new and rather natural way to model off-line packet routing problems, which reduces the problem of off-line packet routing to that of finding edge disjoint paths on a multistage graph. The multistage off-line method can model any kind of routing pattern on any graph and can incorporate the size of the maximum queue allowed in any proces...

This paper presents a novel method for multistage dependency parsing based on dependency direction. In the method, dependency parsing processes are divided into multiple sub-stages, and each stage is in a sequential pattern, which makes it easier to take applicable solutions for different issues in dependency parsing. Meanwhile, dependency parsing in the previous stage provides a clearer contex...

O!-line signature recognition and veri"cation is an important part of many business processes. It can be used in many applications such as cheques, certi"cates, contracts and historical documents. In this paper, a system of two separate phases for signature recognition and veri"cation is developed. A recognition technique is developed based on a multistage classi"er and a combination of global ...

We consider the use of sigmoid functions for multistage detection in asynchronous code-division multiple-access (CDMA) systems. The sigmoid decision function for each stage of multistage detection is derived under the assumption that the residual noise which remains after the multiple-access interference (MAI) cancellation at a stage is Gaussian. It is suggested that the sigmoid function should...
