Analysis of Terrorist Attack Scenarios and Measures for Countering Terrorist Threats

The chapter will present the classification of the types of modern terrorism and describe scenarios and probabilistic models of ordinary, technological, and the so-called intelligent terrorism that are distinguished by their triggering events, propagation modes, damaging factors, probabilities, and consequences. A comparative assessment of these three types of terrorism is presented. Dynamic three-sided models allow assessing the situation from standpoints of terrorists and law enforcement agencies, the administration of the complex engineering system, and analyzing actions and counteractions of various sides involved. A new comprehensive approach to ensuring complex engineering system security is described. This approach is focused not only on the development of protection barriers and safeguards against predetermined list of design-basis scenarios of terrorist attacks but also on increasing the system’s resilience toward beyond design-basis attack scenarios

Theoretical and Experimental Analysis of Structural Properties of Load-Bearing Components of Thermonuclear Tokamak Installations

The chapter presents the results of research carried out in Mechanical Engineering Research Institute of the Russian Academy of Sciences that were focused on validation and application of design diagrams, methods and systems for measuring stresses under the modes of Tokamak instillation cooling and management of electromagnetic fields during startups. The examples of tensometric systems and results of measurements of stresses under cryogenic temperatures and strong magnetic fields as well as results of analysis of the states of stresses and strains of structurally heterogeneous components of load-bearing and conductive structures are presented. Operation conditions and limit states of Tokamak components are considered. Results of research summarized in the chapter demonstrate the correctness of the adopted design solutions, which result in a relatively low level of local stresses in the load-bearing components of the thermonuclear installations

DYNAMICS OF BRIDGE ASSEMBLIES

A methodology is developed for making a dynamic analysis of a bridge assembly with the use of hybrid mathematical models. Obtained are the conditions of conjunction of the bearing structure and attached subsystems which take into account the length of the suspension section. The investigation gives consideration to the influence of the static stres-deformed state on the dynamic properties of the system. The optimum selection of the main design parameters of the bridge assembly served as a basis for minimizing the reaction of the system to the characteristic dynamic effects. This made it possible to reduce the level of vibration of tea-leaf harvesting devices and to provide for the required trajectory of their working membersAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio

Study of strange matter production in the heavy ion collisions at NUCLOTRON

It is proposed to install an experimental setup in the fixed-target hall of the Nuclotron with the final goal to perform a research program focused on the production of strange matter in heavyion collisions at beam energies between 2 and 6 A GeV. The basic setup will comprise a large acceptance dipole magnet with inner tracking detector modules based on double-sided Silicon micro-strip sensors and GEMs. The outer tracking will be based on the drift chambers and straw tube detector. Particle identification will be based on the time-of-flight measurements. This setup will be sufficient perform a comprehensive study of strangeness production in heavy-ion collisions, including multi-strange hyperons, multi-strange hypernuclei, and exotic multi-strange heavy objects. These pioneering measurements would provide the first data on the production of these particles in heavy-ion collisions at Nuclotron beam energies, and would open an avenue to explore the third (strangeness) axis of the nuclear chart. The extension of the experimental program is related with the study of in-medium effects for vector mesons decaying in hadronic modes. The studies of the NN and NA reactions for the reference is assumed

Track Reconstruction with Cosmic Ray Data at the Tracker Integration Facility

The subsystems of the CMS silicon strip tracker were integrated and commissioned at the Tracker Integration Facility (TIF) in the period from November 2006 to July 2007. As part of the commissioning, large samples of cosmic ray data were recorded under various running conditions in the absence of a magnetic field. Cosmic rays detected by scintillation counters were used to trigger the readout of up to 15\,\% of the final silicon strip detector, and over 4.7~million events were recorded. This document describes the cosmic track reconstruction and presents results on the performance of track and hit reconstruction as from dedicated analyses
