The search for the chemical structures that account diffuse interstellar bands remains main challenge in astrochemistry. It relies on experimental verification of obtained from stable isomers laboratory conditions. actual medium, however, is exposed to much harsher Herein we demonstrate isomerisation small, doubly charged polyaromatic hydrocarbon phenanthrene by electron ionisation at relativel...

The search for reliable and efficient global optimization algorithms for solving phase stability and phase equilibrium problems in applied thermodynamics is an ongoing area of research. In this study, we evaluated and compared the reliability and efficiency of eight selected nature-inspired metaheuristic algorithms for solving difficult phase stability and phase equilibrium problems. These algo...

an investigation on the thermal performance of the soil as geothermal heat energy storage medium has been conducted. the thermal characteristics of the soil storage and the heat transfer from a heat exchanger in the soil, surrounding and bottom surface will be discussed. this investigation forms a contribution to a project to realize such storage to be charged from a solar heating system. this ...

The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for pair-produced charged Higgs bosons in the framework of Two Higgs Doublet Models (2HDMs). The data of the four experiments have been statistically combined. The results are interpreted within the 2HDM for Type I and Type II benchmark scenarios. No statistically significant excess has been observed when compared to the Sta...

The discovery potential for charged Higgs bosons at the ATLAS and CMS experiments is discussed with focus on the MSSM. Studies for several decay channels for the charged Higgs boson are presented both for production in top quark decays and gluon-gluon/gluon-bottom fusion. PACS. 12.60.Fr Extensions of electroweak Higgs sector – 14.80.Cp Non-standard-model Higgs

NLSP – LSP decays could have dramatic influence on SUSY phenomenology at LHC. NLSP could have significant lifetime and could be charged. In at least two scenarios detectors must be used in a special way. They were not optimized for detection of heavy (semi)stable charged particles and decaying in flight (neutral or charged) NLSPs. During the last decade both ATLAS and CMS collaboration have dev...

During the past year, two experiments have been carried out at PEP to search for events with a phoJon and large missing transverse momentum. These event searches are particularly sensitive to contributions from supersymmetric photino production but can also be used to search for additional neutrino generations, supersymmetric weak charged currents or the production of any other neutral particle...

Charged particle swarm optimization (CPSO) is well suited to the dynamic search problem since inter-particle repulsion maintains population diversity and good tracking can be achieved with a simple algorithm. This work extends the application of CPSO to the dynamic problem by considering a bi-modal parabolic environment of high spatial and temporal severity. Two types of charged swarms and an a...
