Разработка технологии изготовления червяка двухзаходного симметричного
Выпускная квалификационная работа на тему: Разработка технологии изготовления детали "Червяк двухзаходный симметричный" включает в себя разработанную операционную технологию механической обработки, размерный анализ детали, расчет режимов резания и норм времени. В конструкторском разделе спроектировано две разрезные втулки для фрезерной и токарной операций. Так же рассмотрены вопросы профессиональной и экологической безопасности и безопасность при ЧС. Выполнены оценки экономических аспектов разработки технологии изготовления.The final qualifying work on the topic: Development of the technology for the manufacture of the part "Double-start symmetric worm" includes the developed operating technology of machining, dimensional analysis of the part, calculation of cutting conditions and time norms. In the design section, two split bushings have been designed for milling and turning operations. The issues of professional and environmental safety and safety in case of emergency are also considered. Estimates of the economic aspects of the development of manufacturing technology have been carried out
Multidifferential study of identified charged hadron distributions in -tagged jets in proton-proton collisions at 13 TeV
Jet fragmentation functions are measured for the first time in proton-proton
collisions for charged pions, kaons, and protons within jets recoiling against
a boson. The charged-hadron distributions are studied longitudinally and
transversely to the jet direction for jets with transverse momentum 20 GeV and in the pseudorapidity range . The
data sample was collected with the LHCb experiment at a center-of-mass energy
of 13 TeV, corresponding to an integrated luminosity of 1.64 fb. Triple
differential distributions as a function of the hadron longitudinal momentum
fraction, hadron transverse momentum, and jet transverse momentum are also
measured for the first time. This helps constrain transverse-momentum-dependent
fragmentation functions. Differences in the shapes and magnitudes of the
measured distributions for the different hadron species provide insights into
the hadronization process for jets predominantly initiated by light quarks.Comment: All figures and tables, along with machine-readable versions and any
