Behavioral theories and the neurophysiology of reward,

by Wolfram Schultz - Annu. Rev. Psychol. , 2006
"... ■ Abstract The functions of rewards are based primarily on their effects on behavior and are less directly governed by the physics and chemistry of input events as in sensory systems. Therefore, the investigation of neural mechanisms underlying reward functions requires behavioral theories that can ..."

is variance, and the probability distribution pi is Gaussian. Thus, EU is expressed as f(EV, variance). This procedure uses variance as a measure of uncertainty. Another measure of uncertainty is the entropy of information theory, which might be appropriate to use when dealing with information processing

A low complex scheduling algorithm for multi-processor system-on-chip

by Nicolas Ventroux, Frédéric Blanc - In Parallel and Distributed Computing and Networks , 2005
"... Multi-Processor System-on-Chip (MPSoC) represents today the main trend for future architectural designs. Nonetheless, the scheduling of tasks on these distributed systems is a major problem since it has a central impact on global performances. This problem is known to be NPcomplete and only approxim ..."

Theory of Computing Systems

by M. Mitzenmacher
"... Abstract. It is well known that simple randomized load balancing schemes can balance load effectively while incurring only a small overhead, making such schemes appealing for practical systems. In this paper we provide new analyses for several such dynamic randomized load balancing schemes. Our work ..."

work extends a previous analysis of the supermarket model, a model that abstracts a simple, efficient load balancing scheme in the setting where jobs arrive at a large system of parallel processors. In this model, customers arrive at a system of n servers as a Poisson stream of rate λn, λ<1

Distributed Real-Time Audio Processing

by Nelson Posse Lago
"... Computer systems for real-time multimedia processing require high processing power. Problems that depend on high processing power are usually solved by using parallel or distributed computing techniques; however, the combination of the difficulties of both real-time and parallel programming has led ..."

PRACTICAL EXPERIENCES WITH TASK SCHEDULING STRATEGIES FOR IMAGE PROCESSING APPLICATION ON HETEROGENEOUS DISTRIBUTED COMPUTING SYSTEM

by Kalim Qureshi, Masahiko Hatanaka
"... Heterogeneous Distributed Computing (HDC) system consists of Workstations (WSs) and Personal Computers (PCs). In HDC system, each WS/PC may have different processor and performance. In order to take advantage of this diversity of processing power of a system, an effective task partitioning, scheduli ..."

A compensation procedure for multiprogramming queues

by J Wessels , W H M Zijm , 1991
"... Abstract. In this paper we study a multiprogramming system consisting of an input-output unit (10 unit) and a central processor (CP). This system can be represented by a continuous time Marlmv process with states (m. n). where m and n denote the number of jobs at the CP and the 10 unit respectively ..."

Transactions on Parallel and Distributed Systems

by Systems C. Special-purpose
"... (MMOGs) can include millions of concurrent players spread across the world and interacting with each other within a single session. Faced with high resource demand variability and with misfit resource renting policies, the current industry practice is to over-provision for each game tens of self-own ..."

Materials for an exploratory theory of the network society.

by Manuel Castells , Anthony Giddens , Alain Touraine , Anthony Smith , Benjamin Barber , Peter Hall , Roger-Pol Droit , Sophie Watson , Frank Webster , Krishan Kumar , David Lyon , Craig Calhoun , Jeffrey Henderson , Ramon Ramos , Jose E Rodrigues-Ibanez , Jose F Tezanos , Mary Kaldor , Stephen Jones , Christopher Freeman - The British Journal of Sociology , 2000
"... ABSTRACT This article aims at proposing some elements for a grounded theor y of the network society. The network society is the social structure characteristic of the Information Age, as tentatively identi ed by empirical, cross-cultural investigation. It permeates most societies in the world, in v ..."

While there is oligopolistic concentration of multimedia groups, there is, at the same time, market segmentation

We-Min Chow Central Server Model for Multiprogrammed Computer Systems with Different Classes of Jobs

by unknown authors
"... Abstract: A computer system can usually be interpreted as a closed network with two different types of servers. It is then possible to convert the network into a single server system with state-dependent arrivals. This paper investigates the stationary behavior of a single server queue with differen ..."

First steps in programming: A rationale for attention investment models.
