The search for the maximum of the likelihood function is an iterative numerical procedure and it requires a starting structure for the parameters which is sufficiently close to the real structure to avoid the risk of ending up in a local maximum (Möbus et al., 1998).
This letter presents the results from the MiniBooNE experiment within a full "3+1" scenario where one sterile neutrino is introduced to the three-active-neutrino picture. In addition to electron-neutrino appearance at short-baselines, this scenario also allows for disappearance of the muon-neutrino and electron-neutrino fluxes in the Booster Neutrino Beam, which is shared …

The thickness of the steel strip is an important indicator of the overall strip quality. Deviations in thickness are primarily controlled using the automatic gauge control (AGC) system of each rolling stand. At the last stand, the monitoring AGC system is usually used, where the deviations in thickness can be directly measured by the X-ray thickness gauge device and used as the input …
When working on a machine learning project, you need to follow a series of steps until you reach your goal. One of the steps you have to perform is hyperparameter optimization on your selected model. This task always comes after …
Fig. 1 shows the experimental set-up used in the investigation, a modified CNC 3-axes milling machine. In this set-up, the spindle with the grinding disk has the three translational degrees of freedom x, y and z, whereas the workpiece is stationary (Fig. 1a). An asynchronous electric motor drives the precision spindle by means of pulleys and a belt at speeds ranging …

The numerical values correspond to the composition (Zr 0.45 Hf 0.55 O 2) 0.775 (Y 0.5 Nb 0.5 O 2) 0.225 having tetragonal lattice parameters a 0 = 3.62263 Å and c 0 = 5.25509 Å and monoclinic ...
Search for the best optimum and validation tests with respect to material quality In the previous sections, models for the grinding force and the median defect area have been developed and optimized. The parameters defining the best and second best optima for each optimized characteristic are given in Table 8, Table 9, Table 11, Table 12 ...
In this paper, the correlation between structural and mechanical properties of nanostructured austenitic oxide dispersion strengthened (ODS) steel prepared by powder metallurgy were studied. High efficient milling process was applied to achive an optimal dispersion of ceramic oxide particles in the steel matrix. The austenitic powder with or without Y2O3 addition was …
One citation style used by genealogical and historical researchers is Evidence Style, developed by Elizabeth Shown Mills.[1] It is an extension of the notes/bibliography system from The Chicago Manual of Style.[2] The Chicago Manual of Style gives many examples of citations for different published sources. It provides little guidance for the many different types of manuscript …

1. Introduction. High energy ball milling (HEBM) is known as an economic, simple and yet powerful method for the production of nanostructured and amorphous materials .The prolonged milling of powder mixtures, results in the formation of supersaturated solid solution, non-equilibrium intermetallic compounds as well as the formation of silicides, nitrides, stable or …
Selective laser melting involves melting and solidification of metal powder particles in a track-by-track and layer-by-layer method to fabricate 3D parts. The present investigation focuses on understanding the effect of laser …
This work discusses on the effect of milling parameters on the TiB and TiB2 formation in Ti-50at%B and Ti-66at%B powders, respectively. Both powder mixtures were processed in a planetary ball Fritsch P-5 ball mill under Ar atmosphere, varying the milling parameters: rotary speed (150 and 200 rpm), size of balls (10 and 19mm diameter) and ball-to-powder weight …

RETSCH is the world leading manufacturer of laboratory ball mills and offers the perfect product for each application. The High Energy Ball Mill E max and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time - with only …
Mill parameters are shown in appendix C (120 s mill time). After the titanium nitride is lifted off, the wafer is patterned again using a lift-off polarity and a thick positive resist. Circular apertures are opened using a MIF developer (since the aluminum is encapsulated by corrosion resistant titanium nitride).
This study aims to investigate the effect of machining parameters on the surface topography and composition of Ti-6Al-4V after micro-EDM as well as the effect of elemental composition on the surface microhardness. The surface topography has been studied in terms of quality of machined surface, crater sizes, and the presence of surface defects. Statistical …
