Statistical Covert Channels Through PROXY Server

2005
The paper is devoted to creating a covert channel through a PROXY server. The channel is based upon data permutation in server buffer using the sequence of packets coming from the router connected to the PROXY server. The resulting data flow allows to create a statistical covert channel that transfers information by manipulating expectation and ...

Application of Statistical Proxies to Speed Up Field Development Optimization Procedures

Abu Dhabi International Petroleum Exhibition and Conference, 2008
Abstract Field development optimization is a computationally intensive task due to the large number of reservoir simulation runs required. These simulations can be expensive, especially for large and complex reservoir models. Proxies can be used to efficiently estimate the objective function value for new scenarios and can act to reduce ...

Patent statistics: deciphering a ‘real’ versus a ‘pseudo’ proxy of innovation

Technovation, 2001
Abstract Patent statistics have fascinated economists concerned about innovation for a long time. However, fundamental questions remain as to whether or not patent statistics represent the real state of innovation. As Griliches pointed out, substantial questions involve: What aspects of economic activities do patent statistics actually capture?

Statistical models for use of palaeosol magnetic properties as proxies of palaeorainfall

Global and Planetary Change, 2013
Abstract The magnetic properties of well-drained, near-neutral modern soils exhibit strong relationships with mean annual precipitation (MAP, conventional 30-year averages). The pedogenic magnetic susceptibility is low for low map values (≈ 300 mm/yr), increases with increasing map (up to ≈ 1500 mm/yr), and then flattens or declines for higher ...

Exploring the proper statistical proxy to distinguish random structures

Chinese Physics B
Abstract The canonical description of structures comprises two aspects: (1) basic structural elements and (2) arrangement pattern between those elements. This tidy description has been very successful and facilitates the development of structural physics tremendously, enabling the classification, comparison and analysis of an extremely ...

GPS phase difference variation statistics: A comparison between phase scintillation index and proxy indices

Advances in Space Research, 2013
Abstract Scintillated GPS phase observations are traditionally characterized by the phase scintillation index, derived from specialized GPS receivers usually tracking at 50 Hz. Geodetic quality GPS receivers, on the other hand, are normally tracking at frequencies up to 1 Hz.

'Proxies' and the Public: Testing the Statist Bias in Public Support for Military Aid

SSRN Electronic Journal, 2020
Under what conditions do mass publics support military aid abroad? Specifically, does the American public support extending or ending military aid to a state’s military differently from extending or ending military aid to a non-state armed group? I propose that a statist bias underpins the American public’s attitudes on military aid.

New statistical analysis on diatom proxy data for the estimation of past Southern Ocean properties

2022
The annual sea-ice cycle of formation and retreat influences atmospheric and oceanic processes on a global scale. An understanding of the paleo environmental occurrence of sea ice is therefore necessary when studying past and future climatic change. Currently, diatom abundances provide the most robust proxy for Southern Ocean paleo sea-ice cover and ...

Is Total Expenditure a Valid Proxy for Income in Statistical Matching? a Counterfactual Experiment

A critical but very common experimental situation in statistical matching (SM), where an expenditure survey is linked to a living conditions survey that includes an estimate of income, is the absence within the common variables as a proxy of income or of consumption. Researchers have often been in the situation of giving up the matching and looking for
