The Software Reliability Increase Method

Our investigation purpose is to create the software reliability increase method. The proposed method allows creators to calculate statistic, probabilistic and valuating reliability indices of software components which contain defects. The method’s aim is to take into consideration the statistic components complexity by means of composite metrics. The use of received indices provides for components finding which contain much more defects for refactoring and the first testing process. It contributes to increase identified and corrected defects quantity and improve the software reliability on average about 8%

Test beam studies of the TRD prototype filled with different gas mixtures based on Xe, Kr, and Ar

Towards the end of LHC Run1, gas leaks were observed in some parts of the Transition Radiation Tracker (TRT) of ATLAS. Due to these leaks, primary Xenon based gas mixture was replaced with Argon based mixture in various parts. Test-beam studies with a dedicated Transition Radiation Detector (TRD) prototype were carried out in 2015 in order to understand transition radiation performance with mixtures based on Argon and Krypton. We present and discuss the results of these test-beam studies with different active gas compositions.Comment: 5 pages,12 figures, The 2nd International Conference on Particle Physics and Astrophysics (ICPPA-2016); Acknowledgments section correcte

Some results of test beam studies of Transition Radiation Detector prototypes at CERN

Operating conditions and challenging demands of present and future accelerator experiments result in new requirements on detector systems. There are many ongoing activities aimed to develop new technologies and to improve the properties of detectors based on existing technologies. Our work is dedicated to development of Transition Radiation Detectors (TRD) suitable for different applications. In this paper results obtained in beam tests at SPS accelerator at CERN with the TRD prototype based on straw technology are presented. TRD performance was studied as a function of thickness of the transition radiation radiator and working gas mixture pressure

On the evolution of the model of shifting mode of reproduction

Objective to analyze the evolution of shifting mode of reproduction SMR models to construct the SMR3 model. Methods abstractlogical method methods of modelling the economic dynamics in relation to the switching regime of reproduction of fixed capital. Results despite the fact that fixed capital is necessarily taken into account both in reproduction schemes and in models of economic growth the peculiarities of economy functioning arising from the coexistence of different generations of fixed capital have remained outside both the economic mainstream and heterodox studies. The article briefly describes the theory of switching reproduction regime SMR which fills this gap. Several types of SMR models SMR1 SMR2 SMR3 are considered which differ from each other in the degree of the monetary mechanism development that serves the reproduction processes occurring in the real sector of the economy. By the example of determining the degree of influence of the fixed capital investments structure on the key macro indicators in the Russian Federation the possibilities of the most advanced SMR3 model are demonstrated. On this basis the scenario was simulated of the Russian economy transition from the typical for 2014 financing structure 46 ndash own funds 30 ndash funds of budget and higher organizations 24 ndash other borrowed funds loans to the new structure where own funds are equal to 50 funds of budget and higher organizations ndash 20 other borrowed funds ndash 30 . It is established that this transition contributes to the growth of profitability and GDP. nbsp Scientific novelty the model SMR3 is constructed which allows to take into account the functioning of the banking system and the budget mechanism based on the effect of ergodicity and the fact that the funds coming from all subsystems to the updated subsystem are not only credit resources but also the socalled intracompany funds flowing into the updated subsystem at no cost. Practical significance it is shown that the SMR3 model can be used to carry out practical calculations for various scenarios of socioeconomic development

C. D’Alessandro, D. Shang, A. Bystrov, A. Yakovlev, O. Maevsky: Phase-encoded Transmission for NoC Phase-encoded Transmission for NoC

A novel self-timed communication protocol is based upon phase-modulation of a reference signal. The reference and the data are sent on the same transmission lines and the data can be recovered ob-serving the sequence of events on the same lines. The sender block consists of a reference generator and variable-delay elements, while the receiver includes a delay-locked loop for synchronization and a mutual exclusion element with additional logic (validity bit and FIFO) for data recovery. This protocol exhibits high robustness with respect to transient errors caused by narrow pulse interference, usually associated with crosstalk and radiation.
