background: noise as a most common harmful physical agent in workplaces has some effects on the exposed persons such as hearing threshold reduction, increasing blood pressure, and interference with the speech. the adverse side-effect of noise is one of the scientific areas that have seldom been considered by researchers. the aim of this study was to investigate the effects of occupational noise...

background noise exposure is known as a risk factor for hearing loss and one of its effects is noise-induced stress. cortisol as a stress hormone is used in noise-induced stress assessments. objectives the aim of this study was to measure and compare saliva cortisol concentrations in the morning and evening in normal work day and rest day in both case and control groups and to assess the associ...

In this chapter we survey asset pricing in dynamic economies with heterogeneous, rational traders. By ‘rational’ we mean traders whose decisions can be described by preference maximization, where preferences are restricted to those which have an subjective expected utility (SEU) representation. By ’heterogeneous” we mean SEU traders with different and distinct payoff functions, discount factors...

The authors of this paper present the architecture of a multi-agent system which supports investment decisions. The individual components of the system, the manner of communication between them, the mechanism of assessing the individual agents are discussed here. Combining their common open/close position signals and relearning with the use of the selected data create the never-ending learning ...

The success of the Internet has made some dramatic changes in the way scientists and students are supplied with scientific literature. They can now operate in an information market, where the value of a piece of information is determined by the law of supply and demand. Traders assist the customer in this market. This paper describes a basic approach to trading in the open, distributed, and het...

[NiGo94] Y. Ni and A. Goscinski. Trader cooperation to enable object sharing among users of homogeneous distributed systems. been described in section 3 are applied. This means answering the questions of the introduction either by the system administrator or automatically. In a next step, cost and security aspects will be included. To prepare this, cost have already been included in the general...

We consider a stochastic game between three types of players: an inside trader, noise traders and market maker. In similar fashion to Kyle's model, we assume that the insider first chooses size her market-order then maker determines price by observing total order-flow resulting from transactions. addition classical framework, revenue term is added maker's performance function, which proportiona...

4. Each trader also has a utility function ui : R+ → R+ and wants to maximize his own utility; Suppose each good j has a price pj ≥ 0. Without loss of generality, we assume the price vector p = (p1, p2, . . . , pn) satisfies ∑n j=1 pj = 1. We give the definition of optimal bundles: Definition 2 (Optimal Bundle). Given p ∈ ∆n and bi = ei · p = ∑ j∈[n] eij · pj, then xi ∈ R+ is an optimal bundle ...

We quantify competition among traders by the Herfindahl Index. The index is widely used to assess market concentration and it is computed as the sum of the squared market shares. We study the market for liquidity provision. In an electronic limit order book, liquidity is provided by passive orders and a trader’s market share is the fraction of passive limit order volume that this trader provide...
