Visual Interventions in Collapsing States: Practices, Spaces, Subjects

2014
This thesis presents a framing for analyzing forms of visual interventions by international photojournalists, documentary photographers, and filmmakers during the collapse of Yugoslavia and the Soviet Union (with the focus on Russia) in the 1990s. The framing rests on the distinction between mobile and inert subjects to open new venues for discussions ...

Some diffusion approximations with state space collapse

2006
The known analytical solutions for queueing systems arising as models for computer system performance evaluation require either specific distributional assumptions or special service disciplines. Using diffusion approximations, one can obtain both insights into, and approximations for, systems with more general characteristics. The study of diffusions,

Methods in Diffusion Approximation for Multi-Server Systems: Sandwich, Uniform Attraction and State-Space Collapse

2010
In this chapter, we demonstrate through simple queueing models some of the methods that have been developed for the diffusion approximation. Specifically, we first show how the sandwich method is used to establish the diffusion approximation for a multi-server queue, and next show how the uniform attraction and the state-space collapse method is used ...

State-space collapse in stationarity and its application to a multiclass single-server queue in heavy traffic

Queueing Systems, 2010
The present work is connected to the following results. Recently, \textit{D. Gamarnik} and \textit{A. Zeevi} [Ann. Appl. Probab. 16, No. 1, 56--90 (2006; Zbl 1094.60052)] and \textit{A. Budhiraja} and \textit{C. Lee} [Math. Oper. Res. 34, No. 1, 45--56 (2009; Zbl 1214.60013)] established that, under suitable conditions, a sequence of the stationary ...

A packet-switched network with On/Off sources and a fair bandwidth sharing policy: state space collapse and heavy-traffic

Telecommunication Systems, 2015
We consider a flow-level model for packet-switched telecommunications networks handling elastic flows with concurrent occupancy of resources, in which digital objects are transferred at a rate determined by capacity allocation on each route. The capacity of each node is dynamically allocated to the routes passing by it through a weighted proportional ...

[4] COS-QD - Collapsing-Structure Quantum Dynamics: Discrete, Projectively Quasi-Unitary Time Evolution on the Shell–Filament State Space

We introduce the Collapsing-Structure Quantum Dynamics (COS-QD) framework on the shell–filament state space. Discrete time evolution is implemented by a projectively quasi-unitary collapse operator; the core ingredients are the quantized action (decomposed into local self-adjoint terms), the step generator, and a Kraus decomposition with a natural POVM
