Proxy system modeling can be used in paleoclimatology to improve the interpretation of paleoclimate data. Existing forward models for climate proxies are somewhat scattered in the literature, making their integration difficult. Further, each model has been coded separately, according to disparate conventions. Here, we present a comprehensive, consistently formatted package of forward models for...

In this paper we evaluate the performance of design alternatives for Web proxy cache architectures. Our performance study employs deterministic and stochastic Petri nets (DSPN) as stochastic modeling formalism because DSPN provide an illustrative graphical representation. The presented DSPN models address in particular the sensitivity of the performance of proxy cache architectures on the traff...

Sedimentary proxy records constitute a significant portion of the recorded evidence that allows us to investigate paleoclimatic conditions and variability. However, uncertainties in the dating of proxy archives limit our ability to fix the timing of past events and interpret proxy record intercomparisons. While there are various age-modeling approaches to improve the estimation of the age–depth...

Waterflooding is one of the methods used for increased hydrocarbon production. optimization can be computationally prohibitive if reservoir model or problem complex. Hence, proxy modeling yield a faster solution than numerical simulation. This fast provides insights to better formulate field development plans. Due technological advancements, machine learning increasingly contributes designing a...

This paper describes an interactive graphical user interface (GUI) that can be used for the modeling and analysis of Web proxy workloads. The WebTraff GUI has three main components. First, the WebTraff tool provides a visual front-end to ProWGen, a Web proxy workload generation tool developed in prior work, which can be used for generating synthetic Web proxy workloads of arbitrary length, with...

The primary aim of the present paper is to modify the performance model of Bose and Cheng [1] to a more realistic case when external visits are also allowed to the remote Web servers and the Web servers have limited buffer. We analyze how many parameters affect the performance of a Proxy Cache Server. Numerical results are obtained for the overall response time with and without a PCS. These res...
