ABSTRACT The high nitrogen and oxygen content of energetic dioxadiazine compounds makes them exhibit detonation performance good stability, showing possible application in both military civilian fields. Energetic with intramolecular hydrogen bonds were designed optimized, while introducing —NH 2 , —NHNO —CH 3 —NO —OH as modified groups. bond order, density, enthalpy formation, inter/intramolecular interactions analyzed. Results showed that the skeleton 1,4,2,6‐dioxadiazine...
Shear-wave exploration is an emerging geophysical technique with promising application potential. However, the decoupling phenomenon between baseplate and ground during excitation of S-wave vibrators weakens energy transmission reduces signal-to-noise ratio. To address this issue, paper introduces concepts dynamic stiffness damping to describe interaction under disturbance, establishes a vibration coupling model analyze responses both driven mass reaction mass. Experimental validation...
In the development process of higher vocational education, "tailored" talent cultivation model through deeper school-enterprise cooperation is crucial. This paper analyzes dilemma faced by enterprises and issues in under background transformation steel industry. It explains connotation significance model, introduces various practices their outcomes, summarizes experiences insights, proposes strategies to address existing problems. aims provide a reference for institutions promote continuous...
Underwater mobile acoustic source target localization encounters several challenges, including the unknown propagation speed of signal, uncertainty in observation platform's position and velocity (i.e., platform systematic errors), economic costs. This paper proposes a new two-step closed-form algorithm that jointly estimates angle arrival (AOA), time difference (TDOA), frequency (FDOA) to address these challenges. The initially introduces auxiliary variables construct pseudo-linear...

Dy3+-doped CaF2-SrF2 crystals with various Dy3+ dopant concentrations were synthesized by multicrucible temperature gradient technology (MC-TGT). Dy:CaF2-SrF2 fluorite structured and crystallized in cubic Fm3¯m space group, as characterized X-ray diffraction. The crystallographic site concentration was calculated from the measured density Archimedes’ hydrostatic weighing principle. optical transmission reached over 90% a sample thickness of 1.0 mm. Sellmeier dispersion formula obtained...
The parameter estimation of multiple frequency-hopping (multiple FH) signals with frequency-switching time is a great challenge under conditions in which the number unknown. Due to increasing mobility devices such as unmanned aerial vehicles (UAVs), speed even more demanding. To solve this problem, an algorithm for estimating parameters FH based on compressed spectrum sensing and maximum likelihood (CSML) theory proposed paper. First, received signal split into segments same length,...
The problem that the fuze overload signal sticks and is not easily identified by counting layer during high-speed intrusion of projectile an important factor affecting explosion in specified layer. A three-pole plate dual-capacitance acceleration sensor based on capacitive principle constructed this paper. modal simulation structure carried out using COMSOL 6.1 software, structural parameters are derived from mechanical properties model, finally physical processed fabricated parameters....
Grid Computing is the third revolution of information technology after internet and web. It will change mode sharing distributed resource services finally. This paper presents a historical record advent Grid, then new researched in grid architecture was introduced, which core design system.
The isolation rolling platform inside a passive semi-strapdown inertial navigation system can isolate the high-speed rotation of projectile via bearing to provide low rotating speed environment for angular rate sensors in order further improve accuracy by reducing its measurement range. Aiming at problem that internal cannot withstand high overload, an optimal design method overload buffer structure based on point contact spherical cap is proposed. Changing materials caps reduce deformation...
It has been proved that the construction schedule management was an uncertain problem. Traditional CPM method a good way to define total duration and critical paths but can not solve uncertainty. The paper use path firstly, then defined parameters with Delphi make Monte Carlo simulation. Through simulation results, it is found probability finish work on time only 35.3%. following step sensitivity analysis, through calculation, which large influence treat as key control points. useful problem...
