Streszczenie:

The production cross-sections for a triple gauge boson has been investigated in both the standard model and the minimal supersymmetric standard model, via e+e-→W+W-Z0. All events that contain the Higgs-boson seem to have no influence in this process. At [Formula: see text], this process could be detected with a reasonable cross-section, the production mechanism in this case will be e+e-→Z0→W+W-→W+W-Z0.

Streszczenie:

Adanya suatu permasalahan kendaraan militer pada kapal maritim yang mengalami pendeteksian dan penyerangan dari pesawat tempur karena kapal tersebut terdeteksi oleh adanya radar dari pesawat tempur. Hal ini disebabkan oleh adanya suatu refleksi gelombang elektromagnetik yang mengenai konduktor kapal ketika melakukan tracking radar oleh pesawat. Untuk mengatasi masalah tersebut dapat dilakukan dengan cara mengelabuhi pendeteksian oleh radar pesawat tempur agar tidak dapat melakukan penyerangan ke kapal yaitu menggunakan Radar Absorbing Material (RAM) berupa metamaterial absorber yang diimplementasikan dengan cara melapisi bagian dari body kapal tersebut dengan metamaterial absorber Metamaterial absorber didesain menggunakan perancangan optimum berdasarkan spesifikasi yang telah ditetapkan dan dilakukan simulasi antena dengan menggunakan software CST Microwave Studio 2012. Hasil simulasi metamaterial absorber menunjukkan bahwa metamaterial absorber menghasilkan tiga band (triple band) dari peak S11, dimana band 1 mempunyai nilai S11-parameter -15.547 dB pada frekuensi 8.336 GHz, sehingga menghasilkan nilai absorption rate sebesar 99.92 %. Pada band 2 frekuensi 11.008 GHz mempunyai nilai S11 sebesar -13.278 dB, oleh karena itu menghasilkan nilai absorption rate sebesar 99.78 % dan band 3 dalam frekuensi GHz menghasilkan nilai S11-parameter -8.58 dB pada frekuensi 11.664 GHz, sehingga menghasilkan nilai absorption rate sebesar 98.07 %. Dari hasil simulasi tersebut dapat dikatakan pada tiga band (triple band) dari peak frekuensi mempunyai performansi absorpsi yang baik karena nilai absorption rate lebih besar dari 80 %.

Streszczenie:

Aiming at the triple splitting rolling process of Φ14 mm ribbed bar in small section continuous rolling line, a nonlinear thermal-mechanical coupled finite element model was setup to investigate the splitting mechanism based on the normalized Cockroft-Latham criterion and algorithm of removing elements. From the simulation results, the exit cross section profile, stress and strain distribution of workpiece in each pass is presented. The metal separating in splitting pass and the cause of formation of the insufficient defect was discussed, and the prediction result is in good agreement with that of the practice in the steel company.

The dependence of the bremsstrahlung perpendicular and parallel triple differential cross sections and the linear polarization on the angles and energies of the incident and scattered electron and of the emitted gamma-ray has been studied in the high-energy small-angle hypothesis. The expression used for the bremsstrahlung triple differential cross section is valid in the Born approximation and for an unscreened Coulomb potential of the nucleus.

Streszczenie:

We study the effect of multi-phonon excitations on large-angle quasi-elastic scattering of massive systems using the full order coupled-channels formalism. We especially investigate the role of triple phonon excitations of the target and projectile nuclei on the quasi-elastic scattering cross-section as well as the barrier distribution for [Formula: see text]Cr, [Formula: see text]Fe, [Formula: see text]Ni and [Formula: see text]Zn + [Formula: see text]Pb systems. It is shown that the calculations taken into account, the triple octupole phonon excitations of the target and triple quadrupole phonon excitations of the projectile for these systems can explain the experimental data of the quasi-elastic cross-section and the quasi-elastic barrier distribution. These results indicate that the coupled-channels formalism is still valid even for the very heavy mass systems.

Streszczenie:

Taking portal segment in some shallow-buried tunnel in seismic region with strong motion as objects of study, the finite element analysis method was used to compare and assess the seismic behavior of the tunnel with different cross section shape. The results show that the linings displacement response of the tunnel with different cross section shape differs very minor under seismic load. Meanwhile there exists obvious difference in the lining internal forces of the tunnel with different cross section shape. Among all the tunnel with different section shape, the mechanics situation of the tunnel with triple arched sections is the best. While the section of the tunnel is closer to circular in shape, the mechanics situation of the lining can be effectively improved under seismic load.

Streszczenie:

An efficient Radar Cross Section (RCS) gradient evaluation method based on the adjoint method is presented. The Method of Moments is employed to solve the Combined Field Integral Equation (CFIE) and the corresponding derivatives computing routines are generated by the program transformation Automatic Differentiation (AD) technique. The differential code is developed using three kinds of AD mode: tangent mode, multidirectional tangent mode, and adjoint mode. The differential code in adjoint mode is modified and optimized by changing the “two-sweeps” architecture into the “inner-loop two-sweeps” architecture. Their efficiency and memory consumption are tested and the differential code using modified adjoint mode demonstrates the great advantages in both efficiency and memory consumption. A gradient-based shape optimization design method is established using the adjoint method and the mechanism of RCS reduction is studied. The results show that the sharp leading can avoid the specular back-scattering and the undulations of the surface could change the phases which result in a further RCS reduction.

We have ecamined the charged multiplicity distributions arising from p-p and [Formula: see text] at energies ranging from 30 GeV to 1800 GeV. We find that a portion of each distribution does indeed KNO scale. Those parts of the distributions that do not KNO scale are the result of multiparton collisions. Results from E735 at Fermilab seem to show evidence for both double and triple parton-parton collisions. These multiparton collisions seem to account for the increase in the non-single diffractive cross section in this energy domain.

The recent triple differential cross-section data of Jung for the ionization of helium in the coplanar asymmetric geometry at 250 eV incident electron energy is analyzed within the framework of the second Born (B2) and modified Glauber (MG) approximations. At this energy B2 and MG results, although better than those obtained by using the first Born and Glauber approximations, do not lead to a satisfactory description of the experimental data in all the kinematic situations considered here.

The triple differential cross section for ionisation of hydrogen atoms in the metastable 2s-state by electrons of 250 eV incidence energy has been calculated following the multiple scattering theory of Das and Seal (1993). The results are compared with the first Born results and with the results of some other theories. Additional features are noted in the cross section curves of the present calculation. These offer wider scope for the experimental study of ionisation of hydrogen atoms in their metastable states.

Streszczenie:

Besides the Standard Model (SM)-like Higgs boson h, the Higgs Triplet Model (HTM) predicts the existence of charged and doubly charged Higgs bosons (H±and H±±). In this paper, we focus on the study of the triple Higgs production at the International Linear Collider (ILC): e-e+→hH+H-and e-e+→hH++H–. We present the production cross-sections and discuss the relevant SM backgrounds. Our numerical results show that, with reasonable parameter values, the values of the cross-sections for two processes can reach the level several fb and tens of fb, respectively. Due to large production cross-section and small SM background, the possible signals of H±and H±±might be detected via these processes in the future ILC experiments.

The title of this article signals increasing collaboration across boundaries aimed at understanding and solving complex scientific and societal problems. The article is a reflective analysis of five intersecting keywords in discussions of sustainability and boundary crossing. This genre of discourse studies interprets language use, drawing in this case on a representative sample of authoritative definitions, case studies, and state-of-the-art accounts. The Introduction situates the discussion around the increasing number and size of teams as well as research across both academic disciplines and other sectors, followed by the five keywords that structure the overall argument. Section 2 examines the first of the five keywords, defining interdisciplinarity by marking its alignment with integration, confluence, interdependence, interaction, and balance. Section 3 considers the second keyword—transdisciplinarity—by tracing evolution of a problem-focused connotation, links to sustainability, inclusion of stakeholders, the imperative of critique, and transdisciplinary action research. Section 4 brings together insights on inter- and trans-disciplinarity in a composite “crossdisciplinary” alignment with collaboration, factoring in the nature of teamwork, public engagement, and translation. Section 5 then turns to learning, noting the difference between education and training then emphasizing transformative capacity, double- and triple-loop learning, reflexivity, and a transdisciplinary orientation. Section 6 takes up the final keyword—knowledge—by calling attention to inclusion, indigenous and local perspectives, nomothetic versus idiographic perspectives, the question of fit, and the nature of crossdisciplinary knowledge. The article concludes by identifying future research needs.

Streszczenie:

Besides the SM-like Higgs boson h, the left–right twin Higgs (LRTH) model predicts the existence of three additional Higgs bosons: one neutral Higgs ϕ0and a pair of charged Higgs bosons ϕ±. In this paper, we focus on the study of the triple Higgs production at the ILC, i.e. e+e-→ϕ0ϕ+ϕ-and e+e-→hhϕ0. We present the production cross-sections and the distributions of the various observables, such as, the distributions of the energy and the transverse momenta of neutral and charged Higgs bosons, the differential cross-section of the invariant mass of final Higgs bosons pair, and the production angle distributions of neutral Higgs boson and charged Higgs boson. Our numerical results show that, for the processes e+e-→ϕ0ϕ+ϕ-and e+e-→hhϕ0, the production rates are at the level of 10-1fb with reasonable parameter values while the resonance production cross-section can be significantly enhanced and reach several tens fb. The signatures for signals and corresponding standard model backgrounds are also investigated for the decay mode [Formula: see text].
