This research paper presents the study of modelling and
validating the results of simulation of LiDAR
sensor with actual sensor data. The model can be further utilized for
virtual testing of various ADAS functions.
The virtual sensor is a physics-based sensor capable of emulating the
real sensor. Initially an in-depth study of
Velodyne VLP-16 sensor was carried out in order to parameterize the
virtual sensor model. The sensor is
modelled virtually in Gazebo simulation environment. Gazebo is used
along with ROS (Robotic Operating
Interface) in order to record the sensor data. Data conversion from
sensor message format to Cartesian coordinates has been carried out.
This was done in order to have a common format of actual and virtual
data for
validation. Four different objects were selected for validating the
sensor data. The validation methodology is
based on comparison of actual recorded data generated by Velodyne VLP-16
LiDAR and virtually generated data
by the virtual LiDAR sensor model. The validation proves that the in
case of static scenarios, the virtual lidar
sensor model is 99 % accurate in measuring the range to the object.
Although there is slight deviation from the
actual value, it is in the acceptable limits.

The purpose of the research work was to establish the incidence of the
use of Edublog as a
methodological tool in the achievement of learning located in the
university context of the Faculty of
Industrial and Systems Engineering at Federico Villarreal National
University, using the approach
quantitative, with a non-experimental design, using population of 450
students, after the calculation of the
sample, 202 students were obtained information was collected through
instruments that were validated by
technology experts and their validity with Cronbach's alpha index, the
results of which indicated that both
instruments were highly reliable. The results showed that according to
the perception of the students, there is
a significant high correlation between the study variables.

The project aims at simulation of diesel vehicle and the effect of after
treatment
devices on emissions of vehicle in mathematical environment.
Environmental degradation due to
pollution is increasing also emission norms of vehicles are becoming
more and more stringent.
Newer technologies are developing to attain the target of reduction in
emissions. After treatment
devices like diesel oxidation catalyst (DOC) is used to oxidize CO and
HC, diesel particulate
filter (DPF) is used to trap particulate matter and selective catalytic
reduction (SCR) is used for
reduction of NOx. In this project, simulation of light-duty diesel
vehicle is performed and results
are validated with actual data. Simulation of above devices provided
reliable results as well as
variation of different parameters within the components helped to
improve the efficiency of
system. Based on the reduction of emission, the conversion efficiency of
after treatment system is
calculated. Optimization of geometrical parameters of diesel oxidation
catalyst and diesel particulate
filter is done to further improve the performance of system.
Keywords: Diesel Oxidation Catalyst, Diesel Particulate
Filter, Selective Catalytic Reduction

The state of emergency around the world has caused different
consequences (economic, political, and
socio-cultural variations) unusual, as in the educational environment
where teachers must cope with the situation
with the technological tools available to develop a formative assessment
in a context of confinement, which limits
their teaching work. This article focuses on the strategies used by
teachers in the development of formative
evaluation, the construction of evaluation criteria, and feedback used
during virtual work. The qualitative method
is applied with a phenomenological approach (ethnographic) in which 4
teachers participate in an interview in
order to obtain results that can demonstrate the different evaluation
methods based on educational issues. In
synthesis, the study is complemented in three stages: (a) Descriptive,
(b) Structural, and (c) Discussion. Finally,
the formative evaluation in a sustained and personalized way, using
different means of communication, makes a
follow-up according to what each student needs and allows to know what
each student has managed to develop
during the confinement period, which will allow to propose teaching
strategies and to better adapt the teachers'
practice when returning to the face-to-face modality.

This research project presents the environmental problem of
technological waste management for the
Universidad Nacional Federico Villareal and shows how it is possible to
monitor the process using an information
system to monitor, control, measure and make decisions in each
sub-process of technological waste management.
The project enables monitoring based on data and information. The
recording of collection, storage, reuse and
final disposal of waste is important to control the monitoring process
and reduce the environmental pollution
produced by technological waste. In addition, it implies determining the
favourable acceptance to develop and
implement a monitoring system to control each of the processes in the
life cycle of the technological waste. From
the technological point of view, it also presents the chosen development
methodology, the process flow of the
monitoring management, the modular architecture, the software
architecture, the database design of the solution,
the design and development of the interfaces based on the requirements.
Keywords: Technological waste; waste management; waste
monitoring; monitoring system; software
architecture; environmental contamination
