To improve the digital protection effect of ancient buildings, this study improves the space digital technology, combines the digital
interpolation method to carry out the space digital simulation algorithm research, and combines the BIM simulation technology
on the basis of the improved algorithm to carry out the digital protection processing of the ancient buildings. Moreover, this study
starts from the actual situation to construct an intelligent digital protection system of ancient building. In addition, through the
ancient building spatial data database, this study uses the visualization function and the powerful spatial analysis ability of GIS
technology to design and research the digital protection system of ancient building. Through simulation research, it can be known
that the digital protection system of ancient buildings based on BIM simulation technology proposed in this study has a good
simulation effect and can provide reliable technical support for the protection and subsequent restoration of ancient buildings....
Conducting safe coaching is essential for training police officers, who very often face a
variety of unexpected and dangerous incidents. Their reaction to situations must be rapid and appropriate.
To prepare officers for dangerous situations, but those that cannot be practiced in real life
due to high costs, danger, time, or effort, virtual training seems to be the obvious choice. This article
deals with the development of a calculation algorithm to assess the risk of actions taken on the site
of a traffic incident, which was implemented into the training version of a virtual reality (VR) simulation.
It includes a number of factors and elements that form a scenario of simulations that affect
the degree of its difficulty and the assessment of the performance of each exercise. The different
components of the algorithm that make it possible to assess the skills of the students of police specialist
courses are presented. The acceptance criterion for the developed algorithm shall be the correct
assessment of the student’s skills during the course of the training....
In this work, after improving the formulation of the model on particle transport within astrophysical plasma outflows and
constructing the appropriate algorithms, we test the reliability and effectiveness of our method through numerical simulations
on well-studied galactic microquasars as the SS 433 and the Cyg X-1 systems. Then, we concentrate on predictions of the
associated emissions, focusing on detectable high-energy neutrinos and γ-rays originated from the extragalactic M33 X-7
system, which is an X-ray binary discovered in 2006, located in the neighboring galaxy Messier 33, and has not yet been
modeled in detail. The particle and radiation energy distributions, produced from magnetized hadronic astrophysical jets in the
context of our method, are assumed to originate from decay and scattering processes taking place among the secondary
particles created when hot (relativistic) protons of the jet scatter on thermal (cold) ones (p-p interaction mechanism inside the
jet). These distributions are computed by solving the system of coupled integrodifferential transport equations of multiparticle
processes (reactions chain) following the inelastic proton-proton (p-p) collisions. For the detection of such high-energy
neutrinos as well as multiwavelength (radio, X-ray, and gamma-ray) emissions, extremely sensitive space telescopes and other
γ-ray and neutrino detection instruments are in operation or have been designed like the CTA, IceCube, ANTARES, KM3NeT,
Based on the electrical conductivity model built for graphene oxide, the thermal crosstalk
effects of resistive random access memory (RRAM) with graphene electrode and Pt electrode are
simulated and compared. The thermal crosstalk effects of Pt-RRAM with different metal oxides of
TiOx, NiOx, HfOx, and ZrOx are further simulated and compared to guide its compatibility design.
In the Pt-RRAM array, the distributions of oxygen vacancy density and temperature are obtained,
and the minimum spacing between adjacent conduction filaments to avoid device operation failure
is discussed. The abovementioned four metal oxides have different physical parameters such as
diffusivity, electrical conductivity, and thermal conductivity, from which the characters of the
RRAMs based on one of the oxides are analyzed. Numerical results reveal that thermal crosstalk
effects are severe as the spacing between adjacent conduction filaments is small, even leading to the
change of logic state and device failure....
PLEA is an interactive, biomimetic robotic head with non‐verbal communication capabilities.
PLEA reasoning is based on a multimodal approach combining video and audio inputs to
determine the current emotional state of a person. PLEA expresses emotions using facial expressions
generated in real‐time, which are projected onto a 3D face surface. In this paper, a more sophisticated
computation mechanism is developed and evaluated. The model for audio‐visual person separation
can locate a talking person in a crowded place by combining input from the ResNet network
with input from a hand‐crafted algorithm. The first input is used to find human faces in the room,
and the second input is used to determine the direction of the sound and to focus attention on a
single person. After an information fusion procedure is performed, the face of the person speaking
is matched with the corresponding sound direction. As a result of this procedure, the robot could
start an interaction with the person based on non‐verbal signals. The model was tested and evaluated
under laboratory conditions by interaction with users. The results suggest that the methodology
can be used efficiently to focus a robot’s attention on a localized person....
