Abstract The aim of the study is to demonstrate extent effect that occurs continuous reinforced deep beams when performing a parametric in terms support settlement and different conditions for dual span (CDBs), failure load mode, using ANSYS 2020 nonlinear finite element program. As relied on laboratory conducted by Yang et al. [8]. Six samples were taken from concrete with two spans extension ...

The measurement of the polarized gluon distribution function ∆g(x) from photon gluon fusion processes in electron proton deep inelastic scattering producing two jets has been investigated. The study is based on the MEPJET simulation program. The size of the expected spin asymmetry and corresponding statistical uncertainties for a possible measurement with polarized beams of electrons and proton...

We report our measurement of the weak mixing angle, sin*&, in neutrino-nucleon deep inelastic scattering in the NuTeV experiment at Fermilab. Using separate neutrino and antineutrino beams, we are able to use the Paschos-Wolfenstein relations to extract sin’ Bw with low systematic errors. Our preliminary result is sin’0~(~-~~~“) = 1 m&/m; = 0.2253 f O.O019(stat.) & O.OOlO(syst.), which in the S...

Megavoltage electron beams represent an important treatment modality in modern radiotherapy, often providing a unique option in the treatment of superficial tumours (less than 5 cm deep). Electrons have been used in radiotherapy since the early 1950s, first produced by betatrons and then by microtrons and linacs. Modern high energy linacs typically provide, in addition to two megavoltage photon...

The latest measurements of the cross sections for neutral and charged current deep inelastic scattering in ep collisions at HERA with longitudinally polarised lepton beams are presented. The measured cross sections are compared with the predictions of the Standard Model. Next-to-leading-order QCD analyses of HERA data are also presented. The analyses yield the parton distribution functions of t...

 High-aspect-ratio mechanical structures fabricated using deep reactive ion etching generally have a non-rectangular profile. The profile can severely influence the mechanical performance of the device. We have quantified the profile shape for through-wafer etched beams and presented an analytical model to evaluate the effect of profile shape on silicon lateral suspensions. A design methodolog...

We report the measurement of sin 2 W in ? N deep inelastic scattering from the NuTeV experiment. Using separate neutrino and anti-neutrino beams, NuTeV is able to determine sin 2 W with low systematic errors by measuring the Paschos-Wolfenstein variable R ? , a ratio of diierences of neutrino and anti-neutrino neutral-current and charged-current cross-sections. NuTeV measures sin 2 W (on?shell) =

We use a combination of several different types of lithography to generate Bragg-grating devices. In interference lithography, two coherent laser beams are crossed, generating a standing-wave interference pattern. This standing-wave pattern is used to expose photoresist, yielding a coherent deep-submicron-period grating. This grating can be used directly as the device grating or it can serve as...

The first measurements of the cross sections for neutral and charged current deep inelastic scattering in ep collisions with longitudinally polarised positron beams are presented. The total cross section for ep charged current deep inelastic scattering is presented at positive and negative values of positron beam longitudinal polarisation for an integrated luminosity of 37.0 pb H1 data and 30.5...
