Advances in sensing, communications and data analytics have made it possible to construct virtual replicas of Cyber-Physical Systems (CPSs). Such replicas, known as digital twins, can principle inform decision making during operation evolution the systems they model. This short paper introduces ISoLA 2020/21 series papers on technology practice engineering twins for CPSs. The focus is relations...

We show that sufficiently strong laser beams with two frequencies differing by a cyclotron frequency of a free electron can give rise to strong cyclotron excitation with prohibited and allowed cyclotron orbits as well as to an optical Stark shift. This is due to a combination of relativistic effects and results in multiple isolated branches of excited motion (isolas). The formation of the first...

In this paper we prove a nontrivial lower bound for the determinant of the covariance matrix of quantum mechanical observables, which was conjectured by Gibilisco and Isola. The lower bound is given in terms of the commutator of the state and the observables and their scalar product, which is generated by an arbitrary symmetric operator monotone function. Introduction The basic object in the st...

Cruise ships nowadays can carry more than 5500 passengers and 2200 crew members for an average time of seven days per trip. The cruising industry makes up a large proportion the tourism market, demand is on rise. Despite numbers people board, crime reporting cruise so far relatively low. While ship itself faces security threats, activities board shore provide many opportunities targets flaws to...

ESBLs are now a problem in hospitalized patients throughout the world. The prevalence of ESBLs among clinical isola tes varies greatly worldwide and in geographic areas and are rapidly changing over time. A total of 81 isolates of Enterobacteriaceae ESBLS, have been chosen in order to confirm ESBL-producing isolates, this confirmation was done by inhibitor potentiated disc diffusion test. Of th...

A short survey of the use of neural networks and statistical discriminants in high energy physics for recognition of heavy flavor jets is presented. After illustrating the various neural and statistical classifiers currently used, some assessment of their comparative performance for top and oottom jets is made. Presented at Second Workshop on Neural Networks: from BioloiY to Hiih EneriY Physics...

Why do some images stick in our minds while others fade away? Recent work suggests that this is partially due to intrinsic differences in image content (Isola 2011, Bainbridge 2013, Borkin 2013). However, the context in which an image appears can also affect its memorability. Previous studies have found that images that are distinct, interfere less with other images in memory and are thus bette...

Guest satisfaction is a crucial aspect affecting the performance of hospitality business. Satisfaction recognized as primary driver customer loyalty. feeling guest that their expectations have been met or exceeded. Hence, study sought to examine role housekeeping department towards satisfaction. The case was Isola Sacra Hotel in Italy. literature based. analysis based on findings from preceding...

We show how an island (isola) evolves out of the usual S-curve of steady states of diffusion flames when radiation losses are accounted for and how it eventually disappears when radiation increases further. At small activation temperatures there are never any islands. We show that stable oscillations evolve first out of perturbations of steady states on the S-curve at large Damköhler numbers. O...
