We study source coding in the presence of side information, when the system can take actions that affect the availability, quality, or nature of the side information. We begin by extending the Wyner-Ziv problem of source coding with decoder side information to the case where the decoder is allowed to choose actions affecting the side information. We then consider the setting where actions are t...

to effectively design daylight in buildings, daylight availability data are necessary. although there is a great potential for daylight energy in iran, its use has been hampered by the absence of measured data. in this paper the illuminance data on the vertical south facing surfaces of tehran were estimated using the iesna model. for this propose an illuminance measuring set was used in order t...

Accurate, precise and timely forecasts of flood wave arrival time, depth and velocity at each point of the floodplain are essential to reduce damage and save lives. Current computational capabilities support hydraulic models of increasing complexity over extended catchments. Yet a number of sources of uncertainty (e.g., input and boundary conditions, implementation data) may hinder the delivery...

This paper addresses a rationing problem in a two-level, vertically integrated distribution system composed of one manufacturer and several retail points. The motivating case, developed in the vending machine sector and modeled as a newsvendor-like problem, is representative of many real settings where short-term changes in demand can be substantial while capacity modification is not a viable o...

There are numerous environments or situations where a computer network has one or more constraints. Impact of these constraints can range from minimal user inconveniences to catastrophic reduction of capabilities. These constraints allow availability of information at the cost of abandoning the safety and reliability of traditional routing and security protocols. A number of environments in whi...

preventive maintenance scheduling is to perform a series of tasks that prevents or minimizes production breakdowns and improves the reliability. mathematical models have been developed to solve the preventive maintenance scheduling problem. there are several limitations in the prior work in this area of research. craft combinations are assumed to be given. the craft combination problem concerns...

Absence of network infrastructure and heterogeneous spectrum availability in cognitive radio ad hoc networks (CRAHNs) necessitate the self-organization of cognitive radio users (CRs) for efficient spectrum coordination. The cluster-based structure is known to be effective in both guaranteeing system performance and reducing communication overhead in variable network environment. In this paper, ...

MOTIVATION The diffusion kernel is a general method for computing pairwise distances among all nodes in a graph, based on the sum of weighted paths between each pair of nodes. This technique has been used successfully, in conjunction with kernel-based learning methods, to draw inferences from several types of biological networks. RESULTS We show that computing the diffusion kernel is equivale...

Course Timetabling (CTT) [11] is a popular combinatorial optimization problem, which deals with generating university timetables by scheduling weekly lectures, subject to conflicts and availability constraints, while minimizing costs related to resources and user discomfort. In CB-CTT, students enrol to curricula i.e., (possibly overlapping) collections of courses. Lectures of courses pertainin...

‎In this paper we study the dynamics of the 2D-motion of a particle of monolayer‎. First we consider the usual physical time component and the plan manifold R2, having the polar coordinates. Then a geometric approach to nonholonomic constrained mechanical systems is applied to a problem from the two dimensional geometric dynamics of the Langmuir-Blodgett monolayer‎. We consider a constraint sub...
