We propose a simple model for the behaviour of longterm investors on a stock market. It consists of three particles that represent the stock’s current price and the buyers’, respectively sellers’, opinion about the right trading price. As time evolves, both groups of traders update their opinions with respect to the current price. The speed of updating is controled by a parameter γ; the price p...

In order to improve mixed optical-electrical microwave devices design, a novel modeling of opto-electronic phenomena as photoconduction effect has been achieved. Multiples photo-induced carriers generations/recombinations processes playing a part in semiconductor subtrates under laser illumination are taken into account and modeled by an equivalent electrical circuit. Various types of modulatio...

In this paper we study pattern formation arising in a system of a single reaction-diffusion equation coupled with subsystem of ordinary differential equations, describing spatially-distributed growth of clonal populations of precancerous cells, whose proliferation is controled by growth factors diffusing in the extracellular medium and binding to the cell surface. We extend the results on the e...

The report presents cooperation capabilities of CAD Centre at the Technical University "Moscow Power Engineering Institute" (MPEI) in the area of heterogeneous system design. The problem of system-level synthesis is considered as hardware/ software codesign with result prediction in the early stages of the controled partitioning accounting adjacent effects. This approach avoids apriority restri...

The circuit design problem consists in determining acceptable parameter values (resistors, capacitors, transistor geometries . . . I which allow the circuit to meet various user given operational criteria (DC consumption, AC bandwidth, transient rise times, etc). This task is equivalent to a multidimensional and/or multi objective optimization problem: n-variables functions have to be minimized...

Decisions and actions produced by computer users (observed process) contain much information about their mental models, individual problem solving strategy and underlying decision structure for a given task. Our tool AMME analyses observed processes and automatically extracts a Petri net description of the task dependent decision structure (logical structure). This net is extended by goal setti...

Methods A randomized, double-blind, placebo-controled, parallelgroup, phase II study was conducted. Thirty-six subjects with LAR to DP were randomized to receive Pangraminâ PLUS, ALK, Dermatophagoides pteronyssinus (AIT-DP) or placebo for 24 months. The primary endpoint was total symptoms (TSS) and total medication scores (TMS). Secondary endpoints included: total combined symptom+medication sc...

Cooperative work enables a users group to collaborate in the same project. The use of a cooperative database system enables distributed users to cooperate on large data volumes. We modelize the cooperative work by alternative versions which belong to each participant, and a merge mechanism which is controled by a group supervisor. This model is a variant of the distributed architecture model, c...

The role of the leader in an organization is key factor to determin success organization. By leader, members will be more easily managed and controled. Transformational leadership one style that able create intrinsic motivation for organizational members. This study determine meaning transformational leaders a better work culture company. uses phenomenological method focused on PT. Serkolinas A...

the aim of this study was to develop a derivative of chitosan as pharmaceutical excipient used in sustained-release matrix tablets of poorly soluble drugs. a water-soluble quaternary ammonium carboxymethylchitosan was synthesized by a two-step reaction with carboxymethylchitosan (cmcts), decylalkyl dimethyl ammonium and epichlorohydrin. the elemental analysis showed that the target product with...
