The Message Reporting System of the ATLAS DAQ System
The Message Reporting System (MRS) in the ATLAS data acquisition system (DAQ) is one package of the Online Software which acts as a glue of various elements of DAQ, High Level Trigger (HLT) and Detector Control System (DCS). The aim of the MRS is to provide a facility which allows all software components in ATLAS to report messages to other components of the distributed DAQ system. The processes requiring a MRS are on one hand applications that report error conditions or information and on the other hand message processors that receive reported messages. A message reporting application can inject one or more messages into the MRS at any time. An application wishing to receive messages can subscribe to a message group according to defined criteria. The application receives messages that fulfill the subscription criteria when they are reported to MRS. The receiver message processing can consist of anything from simply logging the messages in a file/terminal to performing message analysis. The inter-process communication is achieved using the CORBA technology. The design, architecture and the used technology of MRS are reviewed in this paper
CVaR minimization by the SRA algorithm
Using the risk measure CV aR in οΏ½nancial analysis has become
more and more popular recently. In this paper we apply CV aR for portfolio optimization. The problem is formulated as a two-stage stochastic programming model, and the SRA algorithm, a recently developed heuristic algorithm, is applied for minimizing CV aR
Calculations of exchange interaction in impurity band of two-dimensional semiconductors with out of plane impurities
We calculate the singlet-triplet splitting for a couple of two-dimensional
electrons in the potential of two positively charged impurities which are
located out of plane. We consider different relations between vertical
distances of impurities and and their lateral distance . Such a
system has never been studied in atomic physics but the methods, worked out for
regular two-atomic molecules and helium atom, have been found to be useful.
Analytical expressions for several different limiting configurations of
impurities are obtained an interpolated formula for intermediate range of
parameters is proposed. The -dependence of the splitting is shown to become
weaker with increasing .Comment: 14 pages, RevTeX, 5 figures. Submitted to Phys Rev.
Integer programming methods for special college admissions problems
We develop Integer Programming (IP) solutions for some special college admission problems arising from the Hungarian higher education admission scheme. We focus on four special features, namely the solution concept of stable score-limits, the presence of lower and common quotas, and paired applications. We note that each of the latter three special feature makes the college admissions problem NP-hard to solve. Currently, a heuristic based on the Gale-Shapley algorithm is being used in the Hungarian application. The IP methods that we propose are not only interesting theoretically, but may also serve as an alternative solution concept for this practical application, and other similar applications. We finish the paper by presenting a simulation using the 2008 data of the Hungarian higher education admission scheme
Quantum and Classical Orientational Ordering in Solid Hydrogen
We present a unified view of orientational ordering in phases I, II, and III
of solid hydrogen. Phases II and III are orientationally ordered, while the
ordering objects in phase II are angular momenta of rotating molecules, and in
phase III the molecules themselves. This concept provides quantitative
explanation of the vibron softening, libron and roton spectra, and increase of
the IR vibron oscillator strength in phase III. The temperature dependence of
the effective charge parallels the frequency shifts of the IR and Raman
vibrons. All three quantities are linear in the order parameter.Comment: Replaced with the final text, accepted for publication in PRL. 1 Fig.

Two-Center Integrals for r_{ij}^{n} Polynomial Correlated Wave Functions
All integrals needed to evaluate the correlated wave functions with
polynomial terms of inter-electronic distance are included. For this form of
the wave function, the integrals needed can be expressed as a product of
integrals involving at most four electrons

The prospect of use of fuel in the form of micro particles (balls with a diameter about a millimeter formed by the fissile material and a protective cover to hold the radioactive fission products) in nuclear reactors is disclosed. Itβs marked that flow ability, large specific surface of heat removal, extraordinary high resistance of micro fuel particles allow to design innovative safe reactors for various purpose: transportable, breeders, high-temperature, high neutron flux etc. Itβs suggested to complete the active zone by bulk heat releasing assemblies. In them the advantages of spherical micro fuel particles and a coolant side supply to the bed through permeable distribution and branch channels are harmoniously combined in these assembles. It is presented the scheme of bulk assemblies and carried out the analysis of modeling of dynamics of a stream in permeable channels. It is shown that the mathematical description of liquid movement in such channels has ambiguity and discrepancy. To eliminate modeling shortcomings a new kinematic image of current in the permeable channels was offered. It was proposed instead of the existing one representing a jet to which particles of coolant were continuously joined or separated on the permeable wall. In the new interpretation the flow in the permeable channel is considered as turn of the stream at its simultaneous expansion or narrowing depending on there is outflow or inflow. On the base of this image the equation for determination of coolant pressure changing in the permeable channel is obtained; reaction of a stream for changing of flow rate increment is established, the tangent component of a velocity on a permeable wall is founded. Thereby the disadvantages of describing of coolant moving in the bulk assembles channels are eliminated. Permeable channels are used not only in nuclear reactors, but also in many other technological devices: catalytic reactors, heat exchangers, filters, collector and distributing systems. The obtained results can be used for designing other devices with permeable channels.Π Π°ΡΠΊΡΡΡΠ° ΠΏΠ΅ΡΡΠΏΠ΅ΠΊΡΠΈΠ²Π° ΠΈΡΠΏΠΎΠ»ΡΠ·ΠΎΠ²Π°Π½ΠΈΡ Π² ΡΠ΄Π΅ΡΠ½ΡΡ
