the results of examination of annual financial statements by independent experts (auditors) are presented in reports. we have tried to examine and evaluate the activities of two important professions of accountancy and auditing in iran, in preparing and validating annual financial statements, and relate these evaluations to group behavior of share – holders and analyses of stock – brokers. for ...

In this work we present and evaluate different automated combination techniques for traffic classification. We consider six intelligent combination algorithms applied to both traditional andmore recent traffic classification techniques using either packet content or statistical properties of flows. Preliminary results show that, when selecting complementary classifiers, some combination algorit...

To avoid co-surge the mass flows should be kept balanced. Still co-surge can occur when operating close to the surge line due to disturbances between the two mass flows. In that case the control system needs to detect the co-surge oscillation and take proper actions. The simulation model is used to evaluate detection and control algorithms, which are then tested in vehicle. −0.25 0 0.25 0.5 0.7...

This paper studies TCP performance focusing on the mean flow transfer delay and the average number of concurrent flows in the system. This is done for a dynamic population of users, rather than a static number of permanent flows. The modeling approach relies on using idealized processor sharing models as a starting point and modifying their properties to take into account some of TCP’s non-idea...

The research reported in this paper develops a network level traffic flow model (NTFM) which is applicable for both motorway and urban roads. It forecasts the traffic flow rates, queue propagation at the junctions and travel delays through the network. NTFM uses sub-models associated with all road and junction types which comprise the highway. The flow at any one part of the network is obviousl...

In this paper, the theory of flow barriers in discontinuous dynamical systems is systematically presented as a new theory for the first time, which helps one rethink the existing theories of stability and control in dynamical systems. The concept of flow barriers in discontinuous dynamical systems is introduced, and the passability of a flow to the separation boundary with flow barriers is pres...

This paper aims to 1) compare financial controls through the main bank system to those of capital markets, 2) analyze the relationship between financial controls through the main bank system and the traditional Japanese accounting practices, and 3) analyze appropriate changes for financial controls and related accounting practices. This paper defines a main bank as an investor, which controls t...

We consider an optimal control problem governed by a system of nonlinear partial differential equations modelling viscous incompressible flows submitted to variations of temperature. We use a generalized Boussinesq approximation. We obtain the existence of the optimal control as well as first order optimality conditions of Pontryagin type by using the Dubovitskii-Milyutin formalism.

A very useful technique a network administrator can use to identify problematic network behavior is careful analysis of logs of incoming and outgoing network flows. The challenge one faces when attempting to undertake this course of action, though, is that large networks tend to generate an extremely large quantity of network traffic in a very short period of time, resulting in very large traff...
