Authors: Ouyang Qianyu
Published: October 2023

This work proposes a unique control method consisting of ameliorated with reinforcement learning renewal module. The combined fuzzy logic and reinforcement learning regime is utilized to promote robust energy management control in complex working conditions. The coupled optimization proposition tackles unforeseen disturbance by two-pronged approach, with fuzzy logic analyzing backbone power contribution schemes while reinforcement learning takes responsibility for improving a higher efficiency strategy. The vehicle dynamic parameters and energy map are co-modeled through learning extrapolation function. Fuzzy rule undergoes efficient feedback revival via modulating factors driven from multi-objective RL reward computation. Meanwhile, reinforcement learning system leverages adaptive fuzzy representation that generalizes coordination potential vectors, effectively extends exploration quality compared to vanilla learning strategy. To this end, this work effectively considers traction condition, separate wheel control, collaborative effort as well as battery aging into holistic management deduction through renewal regime. To resolve transient contradictions stemming from fuzzy structure regulation, a duet pattern regenerating method is developed, which transfers mechanical and electrical considerations into a unified competence factor. The performance of this system is delineated through numerical simulation and experimental results through Simulink. The results provide multi-faceted insights for the field of adaptive control with application to nonlinear dynamics in addition to emergent influence occurring in more advanced models.

Published: October 2023

This study intends to improve the design of front axles for heavy commercial
vehicles, with a major goal of reducing weight while maintaining mechanical
strength. The front axle is critical in supporting the weight of the vehicle and
facilitating steering while effectively absorbing shocks generated by
differences in road surfaces. To achieve these requirements, a front axle beam
that minimizes weight, fuel consumption, and stress on the load-carrying member
must be designed. In this work, finite element analysis (FEA) techniques are
used using CATIA software to assess the structural and mechanical attributes of
several front axle designs. The purpose is to pick the best front axle shape
depending on specific load situations and driving torque needs. The influence of
alternative component shapes on stress and strain distribution is evaluated
using surface changes and ANSYS Workbench numerical simulation software.
Furthermore, the impact of these structural changes on the mechanical
characteristics of the front axle is carefully investigated. The findings of
this study will help to shape front axle designs that strike a compromise
between weight reduction and mechanical strength, therefore improving the
performance and efficiency of big commercial vehicles. This study gives useful
insights into optimizing front axle designs by employing modern engineering
analytical techniques, which may lead to increased fuel efficiency and lower
vehicle maintenance costs.

Engine
Authors: Fu Jiale , Hu Zhiyuan , Fang Liang , Lou Diming , Tan Piqiang , Yin Qi
Published: October 2023

Hybrid vehicles, compared to pure fossil fuel vehicles, have added power battery
pack, high-power electric motors. The space of the aftertreatment is limited, so
the layout position of the aftertreatment system must be optimized. Meanwhile,
the European 7 emission standard reduces the particulate number (PN) limit
particles size from 23nm to 10nm, presenting new challenges for the
aftertreatment system. The focus of this study is to investigate the variations
in particles size distribution and nanostructure of soot particles during the
exhaust along a dedicated hybrid engine aftertreatment system (catalyst carrier
free). Four operating conditions were selected for the test, namely 2000
r/min-0.2 MPa, 2000 r/min-0.8 MPa, 4500 r/min-0.2 MPa, and 4500 r/min-0.8 MPa.
The particles sampling points are before Three-way catalyst (TWC), after TWC,
and after gasoline particulate filter (GPF). Engine Exhaust Particle Sizer
(EEPS) was used to analyze the changes in particle modal distribution,
transmission electron microscope (TEM) was used to analyze the nanostructure of
particles, and Raman spectroscopy was used to analyze the degree of
nanostructure order. The results show that with the exhaust transport, the total
PN decreased by an average of about 64.4% under each operating condition. Taking
the 4500 r/min-0.8 MPa as an example, the proportion of nucleation mode
particles decreased from sampling points 1 to 3, the proportion of accumulation
mode increased, the average diameter of primary particle increased by 20.3%, the
fringe separation distance increased by 2.3%, the fringe tortuosity increased by
2.6%, the fringe length decreased by 2.6%, the fractal dimension increased by
11.2%, the degree of disorder of particles increased.

Published: October 2023

The fuel economy and emission of the hybrid vehicle depend largely on the
selected engine. And the dedicated hybrid engine (DHE) can be controlled to
operate in the optimal operating range because DHE can be decoupled from the
vehicle transmission system. The main purpose of this paper is to improve the
thermal efficiency of the diesel engine under common operating conditions
combined with high compression ratio (CR) and early or late intake valve closing
(IVC) angle. According to the vehicle road spectrum data, the optimal operating
range of the engine is determined to be 1200-1400 rpm and 70%-90% load. Then CR
and IVC angle are optimized by using the calibrated one-dimensional
thermodynamic model of the engine under limited peak combustion pressure
(Pmax). The results show that the adjustment of IVC angle and CR
can control the thermal state at the end of compression stroke. The combination
of CR and IVC angle can achieve the optimal fuel consumption improvement. The
minimum brake special fuel consumption (BSFC) is reduced from 189.2 g/kWh to 184
g/kWh. Based on the thermal process analysis of internal combustion engines, the
effects of CR, IVC, and boost pressure on engine performance are analyzed. The
improvement of thermal efficiency caused by higher CR would be compensated by
the decrease of combustion constant degree. What is more, early or late IVC
angle can reduce combustion phase loss and gas exchange loss. Further, a more
efficient turbocharger can be matched to achieve higher thermal efficiency.

Published: October 2023

The pressure, flow, and temperature of reactants play a crucial role in the
operation of the proton exchange membrane fuel cell (PEMFC), directly impacting
its performance. To accurately assess the stack output characteristics, precise
regulation of the inlet gas temperature (air and hydrogen) is essential. This
study proposes a control structure for maintaining the temperature of the
inlet-stack gas. The primary actuators employed in this control structure are
the heating belt and solid-state relay. An adaptive PI controller is designed
based on self-regulation of the temperature error. The controller's output is
mathematically converted into a PWM signal, enabling it to act on the actuators.
To validate the feasibility of the control structure and controller,
mathematical simulations are performed using MATLAB/Simulink®. Subsequently,
experimental validations are conducted on a PEMFC stack test bench. These
validations encompass step test, robustness test, and operational stability
test. The step test results reveal that the average rise rate of the inlet air
temperature is approximately 6.78°C/min@265NLPM, with the temperature increasing
from 19.1°C to 75.6°C in 500 seconds. The inlet air temperature exhibits no
overshoot, and the maximum steady-state fluctuation is approximately ±0.6°C. The
robustness test demonstrates that the designed controller exhibits good
resilience to large step changes in flow rate (70-140-350NLPM) and set
temperature (40-70°C). Additionally, an 8hour and 20-minute continuous
experiment is conducted to assess the reliability of the control structure
during long-term operation. The maximum absolute error value observed in the
inlet air temperature during this test is 0.7°C, highlighting the excellent
reliability and accuracy of the control structure and controller.
Study on Transient Tolerance Concentration of Cathode Ammonia in
Proton Exchange Membrane Fuel Cells
Authors: Jing Yuan , Lin Rui
Published: October 2023

The performance and lifetime of proton exchange membrane fuel cells (PEMFC) are
affected by impurities in the gas stream. The concentration of ammonia in the
air can exceed 1ppm in a specific area, which is a potential factor in the
degradation of PEMFC performance and lifetime. Investigating the mechanism and
concentration threshold of cathode ammonia poisoning PEMFC is the prerequisite
for preventing catalyst ammonia poisoning. In this work, the effect of
250ppb~5ppm transient contamination on PEMFC performance and impedance is
studied. The results show that the attenuation performance caused by ammonia is
attributed to the increase of impedance, which is mainly reflected in the mass
transmission resistance, followed by the cathode activation resistance, and has
little effect on the charge transfer resistance. The performance is somewhat
recovered after the polarization curve testing, which is related to the voltage
change and the increase in water generated during the high current density.
Through the comprehensive analysis of the voltage and EIS, it is concluded that
the transient tolerance concentration threshold of PEMFC to ammonia is
500ppb.

Published: October 2023

To improve the prediction accuracy of the remaining useful life (RUL) of the
proton exchange membrane fuel cell (PEMFC), an integrated health index (IHI)
including electrical and non-electrical parameters of PEMFC is established, and
the RUL prediction is conducted based on the above index. Firstly, several
operating conditions including the PEMFC degradation information are selected
according to the information theory method. Moreover, the IHI is established by
the sequential quadratic programming method. Secondly, RUL predictions based on
the power and IHI are conducted by the adaptive neuro fuzzy inference system
(ANFIS), respectively. Finally, different results comparisons including power
and IHI differences, differences between experimental and training/predicting
results, amounts of different differences in training and predicting phases, and
RUL prediction results are presented in detail. The results show that the
accuracy of the RUL prediction based on the IHI is higher than that based on the
power. The accuracy at the time of 654 h of the ANFIS based on the IHI is
improved by 40.8% and 30.4% compared with the linear fitting and ANFIS based on
the power, respectively.

Dump Truck was carried out based on the chassis dynamometer. The effects of
different working conditions on energy consumption and emissions were analyzed.
A Parallel hybrid dump truck with diesel in phase VI of China was selected to
test the energy consumption and emissions by using engine mode and hybrid mode
respectively under the conditions of CHTC-D and C-WTVC. The results show that
compared with pure engine mode, CHTC-D condition of heavy hybrid dump truck has
higher energy saving potential than C-WTVC condition, and the energy saving
rates are 23.8 % and 18.3 % respectively; For the hybrid mode, the specific
emissions of CO2 under C-WTVC and CHTC-D conditions were 1071 g/km
and 1010 g/km, respectively. The CO2 emissions in CHTC-D is 5.7 %
lower than that in C-WTVC; The specific emission of CO2 in hybrid
mode is higher than that in pure engine mode, and the CHTC-D and the C-WTVC are
increased by 3.2 % and 4.6 %, respectively. Under CHTC-D condition, the
NOx specific emissions of engine mode are the same as those of
hybrid mode, which are both 0.63g/kg, while under C-WTVC condition, the
NOx specific emissions of engine mode and hybrid mode are 0.18
g/kWh and 1.60 g/kWh, respectively, and the latter has the highest
NOx emissions; The PN emissions of hybrid mode is higher than
that of engine mode, no matter under CHTC-D or C-WTVC conditions.
Numerical Investigations on Formation Process of N
2
O in
Ammonia/Hydrogen Fueled Pre-Chamber Jet Ignition Engine
Authors: Shang Quanbo , Ji Meng , Li Liguang , Deng Jun
Published: October 2023

Ammonia is used as the carbon-free fuel in the engine, which is consistent with
the requirements of the current national dual-carbon policy. However, the great
amount of NOx in the exhaust emissions is produced after combustion of ammonia
and is one kind of the most tightly controlled pollutants in the emission
regulation. Nitrous Oxide (N2O) is a greenhouse gas with a very
strong greenhouse effect, so that the N2O emissions needs to be paid
close attention. In this paper, the CFD simulation of the N2O
formation and emission characteristics during combustion is carried in the
ammonia/hydrogen fueled pre-chamber jet ignition engine. The simulation results
show that the turbulent kinetic energy (TKE) around the orifices of the
pre-chamber is enhanced due to the local temperature difference between the
main-chamber and the pre-chamber, and then the residual ammonia/hydrogen fuel in
the crevice or near the cylinder wall is trapped in the high temperature zone of
the main chamber, leading to the occurrence of secondary combustion phenomenon
and the N2O secondary stage formation peak around 30°CA ATDC. With
the increasing of equivalence ratio (phi), the value of
N2O secondary stage formation peak will decrease and the
influence of the secondary stage peak on the N2O concentration at EVO
moment will also be weakened. And the influence is minimizing at the equivalence
ratio of 1.1. With the increasing of ammonia dissociation degree
(α), the value of N2O secondary stage formation
peak will decrease caused by the reduction of residual fuel, which is due to
enhancement of the efficient combustion. When α=0.3, the
secondary combustion phenomenon will disappear, and the N2O secondary
stage formation peak also disappears synchronously. The concentration of
N2O at EVO moment is almost zero at α=0.4.
Therefore, ammonia dissociation can effectively reduce the emission of
N2O.
Numerical Simulation of the Effect of In-Cylinder Water Spraying on
the Knock and Combustion Characteristics of a Hydrogen-Argon Oxygen
Engine

Published: October 2023

Fossil fuel depletion and air pollution have accelerated the transformation and
upgrading of the internal combustion engine industry. The argon-oxygen
atmosphere engine has the advantages of “zero emission” and high thermal
efficiency, but the knocking problem constrains the engine to operate at a lower
compression ratio. In this paper, the effect of water spraying technology on the
knocking combustion and combustion characteristics of a hydrogen-argon oxygen
engine is investigated by numerical simulation. A one-dimensional thermodynamic
model and a three-dimensional numerical model of the hydrogen-argon oxygen
engine are established and validated by aligning the model with the data of the
real engine. Firstly, investigate the effect of in-cylinder water spraying
timing on knock suppression and combustion characteristics of hydrogen argon
oxygen engines. 570 ° CA to 600 ° CA is the optimal water spraying timing range
for suppressing knock. When 570 ° CA is sprayed, the atomization effect of
droplets in the cylinder is good, and the combustion and power characteristics
are significantly improved. At this time, the water spraying IMEP increases by
14.45%. Therefore, 570 ° CA is selected as the optimal spraying timing. On this
basis, the effect of in-cylinder water spraying mass on the knock suppression
and combustion characteristics of the hydrogen-argon oxygen engine is further
investigated. When the water spraying mass reaches 24 mg, the knock intensity KI
droppes to 0.170 MPa, and the knock phenomenon has been effectively suppressed.
There is no obvious numerical change in KI when the water spraying mass
continues to increase. In terms of power performance, IMEP increases with water
spraying mass and then decreases, and the maximum value of 6.357 bar is achieved
at 25 mg of water spraying mass, which proves that in-cylinder water spraying
can effectively suppress the hydrogen-argon oxygen engine knock phenomenon while
improving the engine power performance.
Improving Dynamic Response of PEMFC Anode Pressure in Droped Load
Scenarios through Split Range Control
Authors: Zhang Junyu , Chen Fengxiang , Pei Fenglai , Li Tao , Xu Shuo
Published: October 2023

The dynamic response of proton exchange membrane (PEM) fuel cells’ anode pressure
and the pressure difference between the cathode and anode significantly
influence the performance and durability of fuel cells. To address the slow
dynamic response of the anode pressure during rapid load drops, this study
proposes a split range control strategy by introducing the hydrogen purge valve
into the anode pressure control. By rational planning the split range block, the
hydrogen purge valve is opened at appropriate times during load drops. To
validate the effectiveness of the split range control, simulations are conducted
under load drop conditions using an 80 kW fuel cell hydrogen and air supply
subsystem model. The simulation results demonstrate that the split range control
reduces the setting time of the anode pressure during load drops by half, with
the most significant improvement observed at 67% load to idle condition, where
the setting time is reduced from 2.6 s to 1.1 s. Furthermore, the pressure
difference between the cathode and anode decreases from 67 kPa to 44 kPa. The
impact of hydrogen purge valve frequency is investigated by comparing
simulations using a 1 Hz low-speed hydrogen purge valve and a 100 Hz high-speed
hydrogen purge valve. The results show that both valves effectively improve the
dynamic response of the anode pressure during load drops, with identical maximum
pressure differences between the cathode and anode. The findings indicate that
the combination of a 1 Hz low-speed hydrogen purge valve and split range control
can improve the dynamic response of the anode pressure during load drops.
Research on the Control Method of Staggered Parallel Boost Structure
in Fuel Cell System
Authors: Ma Tiancai , Liu QiLin , Xie Jiaojiao
Published: October 2023

Fuel cells’ soft output characteristics and mismatched voltage levels with
subordinate electrical devices necessitate the use of DC/DC converters, which
are an important part of the power electronic subsystem of the fuel cell system.
The staggered parallel Boost topology is commonly employed in fuel cell DC/DC
converters. This paper focuses on the control characteristics of the two-phase
interleaved parallel Boost topology in the context of a fuel cell system.
Specifically, we derive the small-signal model and output-control transfer
function of the topology, and design a controller based on frequency
characteristic analysis. Our proposed controller uses a cascaded double-ring
structure and supports both constant current and constant voltage switching
modes. To evaluate the effectiveness of our proposed control strategy, we
conduct simulation and prototype testing. The simulation and DC/DC converter
prototype are configured according to the output characteristics of the fuel
cells, and the experimental results demonstrate the excellent transient and
steady-state characteristics of the DC/DC converter under our proposed control
strategy.
Knee-Point Identification of Battery Degradation Trajectory Based on
Constant Voltage Charging Capacity Variation
Authors: Chen Jianguo , Sun Tao , Zheng Yuejiu , Han Xuebin
Published: October 2023

The turning point in the process of nonlinear aging is a key feature to identify
the nonlinear aging behavior of lithium-ion batteries. In order to identify the
knee-point online, this paper studies the capacity “diving” phenomenon of the
battery during the experiment and the regulation of the appearance of the
turning point during the nonlinear aging process. Then, a knee-point
identification method based on constant voltage charging capacity is proposed,
and the linear and nonlinear stages of battery decay are redefined. Based on the
change of constant voltage charging capacity in the constant current and
constant voltage charging strategy, the method defines the aging process in
which the constant voltage charging capacity remains invariant as the linear
decay stage of the battery, and the aging process in which the constant voltage
charging capacity rises rapidly as the nonlinear decay stage. The intersection
of linear and nonlinear decay is the knee-point of the battery’s aging
trajectory. This method is tested on nickel manganese cobalt oxide (NCM) and
LiFePO4 batteries, and both achieve the knee-point identification
very well. The method can achieve online capacity estimation without obtaining
complete battery aging data.

Published: October 2023

The port is one of the crucial factors in maritime logistics. Green port innovation aims to increase the efficiency of existing resources, reduce the negative impact of the surrounding environment, increase environmental management, and improve the quality of the natural environment around the port. The number of scientific publications regarding green ports proves that this topic has become a global scientific publication trend. Unfortunately, the focus or pressure points of the various publications are so varied that it is difficult to know the consistency and cohesion between discussions and Indonesia as the author's country has not done much research on the application of green ports. Therefore, this study aims to look at trends in global scientific publications regarding the application of green ports in the hope that the interrelationships between concepts and topic shifts from time to time can be identified. The method used is bibliometric analysis. The population of this study was 200 articles searched for data using the Publish or Perish (PoP) application from 2015-2023; 131 articles were obtained as samples that matched the keywords obtained. Researchers used VOSviewer software version 1.6.16 to perform co-occurrence analysis with overlay and network visualization. The results of the VOSviewer software vulnerability analysis have four themes related to the implementation of green ports, namely "regulation," "Shore power," "logistics," and "green port policy," which are still rarely researched and are the latest themes in research. This theme can be used as a reference for further study.

These anticlines arranged in an en-echelon pattern and they expose rocks range in age from Late Cretaceous to Late Miocene. The Late Cretaceous (Campanian – Maastrichtian) succession represented by Bekhme and Shiranish Formations. The lithologies of these rocks are competent and consist of limestone, dolomitic limestone and marly limestone whichare favorable to joint development. Different types of joints were developed in such rocks due to stresses resulted from collision between Arabian and Eurasian (Turkish and Iranian) plates. The joint sets and systems are the most abundant fractures in the rocks of the study area. The chronological relationships of the joints refer that the area had witnessed multiple tectonic pulses in the form of compressional and extensional stresses. The stereonet and the Win – Tensor programs were used to plot the attitudes of joints and deduce their paleostresss orientations. Furthermore, the orientations of deduced paleostresses were plotted onto geological map of investigated area and simulated as paleo trajectories as well. The deduced paleostress direction responsible for folding in traverse 1 was (356° - 195°), in traverse 2 (330° - 168°) and in traverse 3 (353°- 163°).

Music therapy for children and adolescents – A brief overview
Authors: Stegemann Thomas
Published: October 2023

Working with children and adolescents plays an important part in music therapy as a profession – not least because music is of great developmental psychological significance in childhood and adolescence. This article provides an introductury overview of music therapy practice and research in childhood and adolescence.

Music therapy is a safe and and generally well-accepted intervention. Research findings show that the highest quality of evidence for positive effects of music therapy has been found in autism spectrum and neonatal care. Music therapy with children and adolescents can act as an effective non-pharmacological alternative and complement to other disease-specific therapies.
A personal reflection on challenges facing music therapy education, training and clinical practice
Authors: Clements-Cortes Amy
Published: October 2023

Music used in connection with health and wellness is not a new concept. Music therapy is one discipline that uses music and has developed at various speeds internationally. Since the day I first learned about music therapy I have been advocating further understanding of the discipline, and for its inclusion in multiple contexts. I situate myself in the paper with the start of my own journey into music therapy and provide a short personal reflective overview of three overarching issues I see impacting education, training, and clinical practice of music therapy and its continued development. The World Federation of Music Therapy and the International Association for Music and Medicine will be briefly described with respect to their impact as two large international organizations seeking to advance music therapy and music medicine in healthcare. The essay is offered as an opportunity for educators, practitioners, and researchers to consider and reflect on the factors they see impacting our profession to work towards advancing music therapy and actioning the challenges facing the discipline. Some action steps are offered such as ensuring ethical practice, continuing advocacy efforts, increasing opportunities and avenues of knowledge translation, and developing collaborations. It is hoped that reflecting on these experiences will further dialogue to advance different, non-Western perspectives of music therapy, and to learn how to honor multiple ways of supporting therapeutic music and healing experiences without centering Western approaches or perspectives.
Harvesting integrative music therapy in critical care settings throughout the lifespan
Authors: Loewy Joanne V.
Published: October 2023

Our bodies as instruments include systems which co-regulate, as integrative mechanisms. The cardiac and respiratory systems are inter-dependent, and with music, one of these systems can directly have an impact upon the other. The wind of the body integrates how direct oxygen can maintain our blood flow. Particularly in the playing of live music, such activity coordinates, synchronizes and ultimately influences how we think and feel. Neurologic systems are meant to integrate and music can make such amalgamation stronger-leading toward increased capacity for experiences of functional flow. The IAMM (International Association for Music and Medicine) emblem reflects the integrative mission, and the words “I am” works well and implies a useful reminder for us to think about how music and medicine is inclusive of sounds and systems that we are venturing to know better. Specifically, amongst our unified vision, which began in 2008, was the idea that integration of our research and practice not only makes us more deeply and broadly informed, but additionally can enhance the scope of practice for practitioners and clinicians.
Availability of Land, Water, Human and Technology Resources in the Development of Food Estate Areas in Merauke-Indonesia
Authors: Untari
Published: October 2023

The development of a food estate area in Merauke requires the availability of adequate resources in terms of quality and quantity. The research objective is to analyze the availability of resources in the development of industrial estates based on agricultural production produced in the development of food estates . The research was conducted in the food estate development area, namely Merauke Regency, analyzing secondary data. The data were analyzed from spatial data and then analyzed using a qualitative descriptive analysis approach. Some observation indicators are data on the availability of agricultural land for cultivation, analysis of potential water sources and needs, availability of human resources, and supporting infrastructure. The results of the analysis show that the availability of Merauke's land resources for the food estate is sufficient in terms of quantity and quality for agricultural cultivation, but has not been supported by adequate human resources, namely farmers and agricultural extension workers. Likewise with the availability of water resources and infrastructure facilities such as road networks, ports, electricity, and irrigation networks, it is necessary to revitalize existing facilities and add basic infrastructure networks for the development of a food estate area in Merauke.

Merauke Regency is a lowland area that has soft soil which predominates. One of the methods to overcome the subsidence in silt soil, it is necessary to strengthen it by using geotextiles. The function of the geotextile is to hold the soil surface so that there is no subsidence in the soil. This study aims to determine the carrying capacity of silt soil before and after being given geotextile reinforcement.The study used an experimental method using the addition of Geotextile (non-woven type TS600) to strengthen the carrying capacity of silt soil. The silt soil carrying capacity test was divided into several variations, namely without using geotextile reinforcement and reinforced with 1 layer, 2 layers, and 3 layers of geotextile at a depth of 10 cm, 20 cm and 30 cm.The results of research conducted in the laboratory, the use of geotextile materials to increase the carrying capacity of silt soil has increased compared to the initial conditions. Soil without using geotextiles has a greater decrease, namely at a load of 5 kN there is a settlement of 20.3 mm. By using a single layer geotextile reinforcement material at a load of 5 kN there was a decrease of 10.97 mm, while using a two layer geotextile reinforcement material at a load of 5 kN there was a decrease of 8.09 mm, and using a three layer geotextile reinforcement material with a load of 5 kN there was a decrease of 6.01 mm. It can be concluded that the use of geotextile reinforcement can reduce the settlement of silt soil.

This research discusses the use of a Convolutional Neural Network (CNN) with the MobileNetV2 model in the real-time detection of human facial expressions. This research aims to develop a human face expression detection system using deep learning algorithms. This study used the observation data collection method and obtained secondary data from the FER2013 data set which contains 28,709 training samples, 3,859 validation data sets, and 3,859 test samples, for a total of 35,887 images with a resolution of 48x48 and seven categories of facial expressions. The training results showed that the CNN model using MobileNetV2 achieved an accuracy of 57% in the training process and 51% in the validation process. Based on the analysis of these results, testing using a confusion matrix with an accuracy of 51% concluded that the model was unable to properly recognize patterns of data with disgust and fear categories, leading to low accuracy. Some factors contributing to the system's inability to recognize expressions were due to similarities between facial expressions such as sad and fearful, or sad and disgusted. This study provides new insights into the development of technology for detecting human facial expressions using deep learning and the MobileNetV2 model.

Research objectives to determine the effect of treating pineapple leaf fiber (PLF) with liquid smoke on the tensile toughness of composites and the impact strength of pineapple leaf fiber (PLF) reinforcement. The Method of immersing the fiber with liquid smoke was done in 1, 2, and 3 hours, then heating it in the oven at 40⁰c for 30 minutes. A tensile and impact test specimen following the ASTM D638 – Type IV standard and ASTM D5942 standard. The tensile strength of the composite at 1 hour of treatment was 64.42 MPa; at 2 hours, it increased by 72.53 MPa, and at 3 hours, it increased again by 74.65 MPa. In the composite impact test with fiber reinforcement, the 1-hour treatment was 9.32 J/m², the 2-hour treatment increased by 13.44 J/m², and the 3-hour immersion decreased by 10.21 J/m². The effect of liquid smoke treatment processing on PLF on the tensile strength and impact toughness of the composites shows that the PLF reinforcing composite experienced the most significant change in tensile strength at 3 hours of treatment, and impact toughness occurred at 2 hours of treatment; this shows that liquid smoke can change the strength of PLF to be stronger and tougher.
