This paper presents an effective fruit fly optimisation algorithm (FOA) to solve the steelmaking casting problem. First, we model the realistic problem as a hybrid flow shop (HFS) scheduling problem with batching in the last stage. Next, the proposed FOA algorithm is applied to solve the realistic HFS problems. In the proposed algorithm, each solution is represented by a fruit fly. Each fruit f...

High frequency stimulation (HFS) is used to treat a variety of neurological diseases, yet its underlying therapeutic action is not fully elucidated.

A new result for the hadronic vacuum polarization correction to the muonium hyperfine splitting (HFS) is presented: ∆ν(had – vp) = (0.233 ± 0.003) kHz. Compared with previous calculations, the accuracy is improved by using the latest data on e+e− → hadrons. The status of the QED prediction for HFS is discussed.

In hesitant fuzzy sets (HFSs), which are generalized from fuzzy sets, the membership degree of an element to a set, for which decision-makers hesitate while considering several values before expressing their preferences concerning weights and data, can be assigned one or more possible precise values between zero and one. If two or more decision-makers assign an equivalent value, that value is o...

High-fidelity simulation (HFS) is an educational tool commonly used by professional education programs of medicine and nursing for student training and assessment. Although its use in occupational therapy (OT) education is emerging, implementation of simulation in OT education varies broadly across programs, and, in general, the tool remains underused. This paper describes how the OT education ...

We determine the Zemach moments of hydrogen and deuterium for the first time using only the world data on elastic electron-proton and electron-deuteron scattering. Such moments are required for the calculation of the nuclear corrections to the hyperfine structure of these hydrogenic atoms. We compare the resulting HFS predictions to the available high-precision data and provide an estimate of t...

The scheduling of flow shops with multiple parallel machines per stage, usually referred to as the Hybrid Flow Shop (HFS), is a complex combinatorial problem encountered in many real world applications. Given its importance and complexity, the HFS problem has been intensively studied. This paper presents a literature review on exact, heuristic and metaheuristic methods that have been proposed f...

We calculate the hyperfine structure constant for the Eu isotopes with shell model wave functions. The calculated results are compared with those predicted by the Moskowitz-Lombardi (M-L) empirical formula. It turns out that the two approaches give the very different behaviors of the hfs constants in the isotope dependence. This should be easily measured by experiment, which may lead to the uni...

Hesitant fuzzy set (HFS), which can be accurately and perfectly described in terms of the opinions of decision makers, is considered as a powerful tool to express uncertain information in the process of multi-attribute decision making (MADM) problems. The core of the HFS is the hesitant fuzzy element (HFE).This paper developed a method, which using the interval probabilistic hesitant fuzzy elem...

This paper describes a utility named ruf that reads files from an unmounted file system. The files are accessed by reading disk structures directly so the program is peculiar to the specific file system employed. The current implementation supports the *BSD FFS, SunOS/Solaris UFS, HPUX HFS, and Linux ext2fs file systems. All these file systems derive from the original FFS, but have peculiar dif...
