Generalized span categories provide a framework for formalizing mathematical models of open systems in classical mechanics. We introduce LagSy and HamSy that, respectively, categorical the Lagrangian Hamiltonian descriptions mechanical systems. The morphisms correspond to such systems, composition construction from subsystems. Legendre transformation gives rise functor that translates perspecti...

I review recent applications of the open quantum system framework in understanding quarkonium suppression heavy-ion collisions, which has been used as a probe quark-gluon plasma for decades. The derivation Lindblad equations both Brownian motion and optical limits their semiclassical counterparts is explained. hierarchy time scales assumed justified from separation energy nonrelativistic effect...

data envelopment analysis (dea) technique was used to analyze the efficiency of farmers, discriminate efficient farms from inefficient ones and to identify wasteful uses of energy for orange producers in khouzestan region. data were collected from 125 watermelon producer by using a face-to-face questionnaire. results revealed that total energy consumption in plasticulture and open-field waterme...

many projects on developing electronic health record (ehr) systems have been carried out in many countries. the current study was conducted to review the published data on the utilization of open source ehr systems in different countries all over the world. using free text and keyword search techniques, six bibliographic databases were searched for related articles. the identified papers were s...

in this paper, distributed parameter process systems behavior is studied in frequency domain. based on the dominant gain concept that is developed for such studies, a method is presented to control distributed parameter process systems. by using dominant gain concept, the location of open loop zeros, resulted from the time delay parameter in the process model, were changed from the right half p...

in order to compare sampling efficiencies of total and inhalable dust methods, three airborne dust sampling systems , 7-hole sampler , close and open face filter cassette were compared side-by-side , as stationary and for the personal samplers , in a wood working industry to evaluate their relative efficiency. a total of 162 samples were collected. the study of particle size distribution by cas...
