LaserLynx combines with FieldLynx event software to integrate laser measurements across the FinishLynx results network with meet management databases. The findings of this research help to reduce the thermal stress in laser powder bed fusion. LaserLynx is a laser-based electronic distance measurement device that produces accurate, computer-generated measurements for field events (throws: Shotput, Javelin, Discus, and Hammer and horizontal jumps: Long Jump and Triple Jump). The simulated results were well validated by the experimental data. To reduce the residual stress, the length of the scan track should be reduced while the laser jump speed should be increased as much as possible to make the post-heat peak close to the fusion temperature of the material. The influence of the laser jump speed on the stress perpendicular to the scan direction was greater than that along the scan direction, whether in a short scan track or in a long scan track. Compared with the long scan track, the thermal stress distribution varies more sharply with the laser jump speed when using the short scan track. There are several criteria that can help us determine when to jump up to one of these bigger lasers. Lasers produce a very narrow beam of light. It is quite different from a light bulb or a flash light. The effect of the laser jump speed on the post-heat peak was greater than the pre-heat peak. The letters in the word laser stand for L ight A mplification by S timulated E mission of R adiation. The pre-heat peak, the heat peak and the post-heat peak increased with the laser jump speed. The temperature distribution reached a stable state when the laser jump speed was above 5000 mm/s. It was found that the temperature of the scanned region rapidly increased as the laser jump speed increased from 100 mm/s to 1000 mm/s.

Gradient grid and gradient time step were used to further improve solution efficiency. The 100 kHz measurement rate reveals the time dynamics of titanium combustion-illustrating the potential for broadband multispecies monitoring in dynamic fireball environments.A 3D thermo-mechanical finite element model was developed to study the effect of the laser jump speed on the temperature distribution and thermal stress in laser powder bed fusion (LPBF) of Ti6Al4V alloy. Typical signal-to-noise ratios for the TiO and AlO absorption spectra are 22. This work marks, to our knowledge, the first quantitative absorption measurement of TiO ( $$, $\Delta v = 0$) temperature is 3010 K, whereas TiO has a mean temperature of 2095 K both agree well with previous literature. Fireballs are produced by igniting metal/ammonium perchlorate powder beds on a thermal-jump apparatus. Supercontinuum laser absorption spectroscopy is applied to energetic material combustion fireball environments using the visible spectrum for temperature and column density measurements of key metal combustion intermediates TiO and AlO. Jump speed (m/s), the speed at which the predicted position of the laser beam. In the process, they stimulate other electrons to make the downward energy jump and can cause the emission of more photons of the same wavelength and phase. This rope is designed specifically for athletes still working on their technique and learning to master jump rope skills. The Again Faster Evolution Rope features lightweight handles paired with our heaviest cable.

Separate search groups with parentheses and Booleans.1a), it fires a single exposure at the strut location for a specified period of. To create a strut with the single-exposure approach, instead of the laser scanning a contour and hatching the intersecting geometry on a 2D slice (Fig. Keep it simple - don't use too many different parameters. Only a few researchers have utilized a single-exposure or point-like-exposure strategy for manufacturing struts or porous structures,.
