Effectiveness of Titanium Dioxide Nano Fillers on Sisal fiber for
Enhanced Mechanical Properties and Occupant Protection in Hybrid
Nanocomposites
Authors: Natrayan L. , Seeniappan Kaliappan
Published: February 2024

Vehicle occupant protection remains a critical concern in the field of
crashworthiness technology. When integrated into polymer nanocomposites, natural
fibres like sisal offer a high strength-to-weight ratio that can contribute to
effective energy absorption during collisions. However, these fibers present
challenges, such as poor hydrophilicity and moisture retention. This study
employs compression molding techniques to create hybrid composites of sisal
fibers, epoxy, and titanium oxide nano fillers. We particularly investigate how
fiber orientation and the concentration of nano fillers can optimize mechanical
and thermal properties, thereby enhancing occupant protection features. Our
findings demonstrate that the orientation of sisal fibers and the incorporation
of titanium oxide nano fillers in the epoxy matrix significantly influence the
composite's mechanical and thermal characteristics. Composites reinforced with
continuous sisal fibers exhibited an 11%-18% increase in impact strength
compared to those with randomized fibers. Additionally, a 3% improvement in
hardness was recorded for the same comparison. In the context of nano fillers, 8
wt.% of titanium oxide added to woven sisal fibers resulted in a peak tensile
strength of 81.25 MPa. When 6 wt.% was added to woven sisal fibers, the
composite reached an impact strength of 31.58 J and showed enhanced hardness
properties. These improvements in mechanical properties are particularly crucial
for energy absorption and dispersion, key factors in occupant protection during
vehicular crashes. Interestingly, the density of composites was notably lower
with 2 wt% TiO2 compared to those with 4 wt% TiO2, a
factor attributed to the high-density nature of the nanoparticles.
Impact of Kenaf Fiber and Inorganic Nanofillers on Mechanical
Properties of Epoxy-Based Nanocomposites for Sustainable Automotive
Applications
Authors: Kaliappan S. , Natrayan L.
Published: February 2024

Due to the increasing demand for lightweight and eco-friendly materials in the
automotive sector, alternative fibers like kenaf are gaining attention as
potential materials for car components. This study aims to evaluate the impact
of fly ash and Al2O3 nanomaterials on the mechanical and
thermomechanical properties of kenaf fiber-reinforced composites, particularly
for automotive applications. Various composites were produced and tested using
standard manual fabrication methods for key mechanical properties such as
tensile strength, flexural strength, inter-laminar shear strength, hardness, and
impact resistance. Adding kenaf fibers, fly ash, and Al2O3
nanofillers to epoxy composites demonstrated a noticeable improvement in the
thermomechanical properties of the resulting material. This enhancement is
attributed to improved interfacial bonding and uniform distribution of the
nanofillers within the polymer matrix. In our analysis,
Al2O3 nanofillers had a more significant impact on the
composite's performance than fly ash. A comparative study of different composite
formulations revealed that the C-type composite had superior tensile properties,
exhibiting a tensile strength of 86.74 MPa and a modulus of 5120.78 MPa. The
A-type composite excelled in flexural tests, showing a bending strength of
101.54 MPa and a modulus of 8690.75 MPa. Meanwhile, the B-type composite
showcased the highest impact resistance, hardness, and ILSS values, recording
7.51 KJ/m2 for impact, 69.47 D for hardness, and 29.14 MPa for ILSS.
This research indicates that kenaf fiber composites reinforced with fly ash and
Al2O3 nanofillers are promising for automotive
applications by offering enhanced mechanical and thermomechanical
performance.

Significance of the Ferrous Coat
Authors: Sambath S. , Francis Xavier J. , Jayabalakrishnan D. , Suthan R. , Zahir Hussain M.
Published: February 2024

The ferrous deuteroporphyrin cast Fe alloy and nickel-coated steel were lap
welded successfully using the mechanical stir welding process. It was able to
weld junctions with full strength and fracture on the base metal side of
nickel-coated steel during the welding process, but ferrous alloy and nickel
steel could not be welded together. It was proposed that the joining technique
and function of the Ni coating be used in the friction stir lap welding of
Ni-coated steel and aluminum alloy. The Ni coating improved both the weldability
of iron and steel, resulting in the production of a Fe-Ni eutectic structure
with a low melting point at the interface of the two materials. It is possible
to successfully fuse steel and ferrous metals together.

Published: February 2024

This study delves into the innovative realm of synthesizing surface alloyed
materials by utilizing copper-based metamorphic powders subjected to
high-intensity electron beam irradiation. The process involves depositing
metamorphic particles onto a stainless-steel substrate, and subsequently
exposing the assembly to a powerful electron beam, resulting in the development
of distinct surface alloyed layers. A notable advancement was achieved by
introducing a second layer of metamorphic powders over the existing alloyed
layer, followed by further treatment with the electron beam. The alloyed layers,
characterized by a volumetric concentration ranging from 60 to 67%, exhibited a
fascinating phenomenon— the formation of abundant borate crystals with the
chemical formula Al2.56Fe1.75Ni0.84. This crystal presence significantly
elevated the hardness of the surface alloyed layers, showcasing an impressive
five to sevenfold increase compared to the substrates. Importantly, the alloyed
layers demonstrated remarkable thermal stability, successfully enduring a
rigorous test at 450 degrees Celsius. The subsequent Vickers hardness
measurement, registering at 300 VHN, underscores the substantial and enduring
hardness achieved. Beyond these core findings, this study sheds light on the
potential of alloyed-surface materials in demanding applications requiring
robust heat resistance and exceptional wear resistance. The methodological
synergy of metamorphic powders and electron beam irradiation serves as a
promising avenue for the development of advanced materials with heightened
mechanical properties. Furthermore, this research opens avenues for future
investigations into the specific structural and compositional attributes
contributing to the observed material enhancements.

Published: February 2024

This study aims to assess the feasibility of utilizing a B20 blend, consisting of
20% ethanol and 80% diesel, as a potential alternative to diesel fuel in a
compression ignition engine with a single cylinder. Ethanol, a commonly utilized
biofuel, is renowned for its elevated oxygen content, which contributes to its
efficacy as an oxygenator, hence augmenting fuel combustion and mitigating
pollutants. The primary objective of our study is to evaluate the long-term
durability and corrosion impacts of B20 fuel in comparison to a conventional
diesel-only model. In a series of eight tests, each lasting 12.5 hours, it was
observed that the B20 engine demonstrated enhanced long-term mechanical
durability. Nevertheless, the introduction of ethanol blending resulted in the
dilution and contamination of lubricants, as indicated by the observed rise in
component wear and carbon deposition over a 100-hour testing period. Viscosity
and contamination tests were employed to detect the presence of impurities. The
wear test revealed a consistent increase of 7% in iron (Fe) content per test,
while sulfate contamination exhibited a growth rate of 8.7% per test. The
present study underscores the potential of B20 as a viable substitute for diesel
fuel, and proposes prospective directions for further research to enhance its
efficacy.

and are easily available in the market. The improper brakes result in serious
problems in vehicles. The main idea of this paper is to design a braking system
for a two-wheeler application. The paper discusses the design, analysis, and
simulation of disc brakes. The disc is first selected using the standard brake
disc calculation. To verify the selection of disk, torque at wheel and torque at
the disc are compared. Thermomechanical (Transient) analysis is done on ANSYS
2021 to check for the effect of braking force applied by the disc on the rotor
disc. The mathematical model of the ABS model is done on Scilab Xcos. The main
aim of studying the system using a mathematical model is to verify if the
selected disc brakes are safe enough to be installed on a two-wheeler. The
mathematical model also has stopping distance and the stopping time as the
output which validates the selection of the disc. Hence best-suited brakes are
selected based on the performance and the analysis.

This article explores the impact of As-built versus annealed Fused Deposition
Modeling (FDM) on the mechanical properties of test samples fabricated from two
distinct materials: Polyamide 6 (PA6) and PA6 with carbon fiber filament.
Employing the FDM technique, these samples were meticulously produced, with
significant process parameters maintained at optimal values. Two sets of printed
specimens were prepared for examination, one composed of PA6 and the other of
PA6 with carbon fiber (CF) reinforcement. The first set was subjected to
mechanical testing in its As-built condition, while the second set underwent an
annealing process utilizing a muffle furnace. The annealing reduces internal
stresses, enhances interlayer adhesion, and promotes crystallinity. For both the
sent samples exposed to comprehensive assessments to evaluate various mechanical
performance attributes, including hardness, impact strength, tensile strength
and flexural strength. The results of this study elucidate that PA6 with carbon
fiber exhibited superior mechanical properties than PA6. In further, this study
offers valuable insights into the influence of FDM post-processing techniques,
such as annealing, on the mechanical behavior of printed components. In FDM
Annealed PA6 with carbon fiber emerged as the combination with the most superior
mechanical properties across hardness, impact strength, and tensile strength.

The wide applications of aluminum composites in the defense, automotive and
aerospace industries interest researchers in developing hybrid nanocomposites
with specific properties such as high strength, hardness, and wear resistance.
The aluminum was reinforced by silicon carbide (SiC) nanoparticles with a
constant weight composition, and the spark plasma sintering process fabricated
zirconium dioxide (ZrO2) nanoparticles with a different weight
composition. The hybrid composite material’s density, porosity, and hardness
were assessed using the SEM images of composites and hybrid nanocomposites that
were effectively created by the sintering process without particle
agglomeration. A pin-on-disc device was used for the wear test, with different
input parameters such as weight (20, 25, 30, and 35 N), varying sliding distance
(300, 500, 700 and 900m) and diverse sliding speeds (1, 1.5, 2 and 2.5 m/sec).
The hybrid nanocomposite hardness increased to 52% of the S4 sample due to the
15% ZrO2 nanoparticle reinforcement and it was also noticed that the
S4 (Al/5% SiC/15% ZrO2) sample of hybrid nanocomposite had a higher
wear resistance than the S1 (Al/5% SiC) sample composite.

Published: February 2024

The current research focuses on enhancing the performance of Si solar cells by
using Er2O3 (Erbium Oxide) in cubic crystalline nature serves as an
anti-reflection coating material. An anti-reflective coating aims to improve the
Efficient Power Conversion (EPC) of polycrystalline silicon wafers solar cells
(PSSC) utilised in solar roof panels of the automotive sector. It also exhibits
superior light transmittance and least light reflectance, which eventually leads
to the increase EPC. Erbium oxide helps to convert low energy photons into high
energy photons. The incident photons, which lies on the solar cell, gradually
losses its energy to travel in a denser medium and dissipate in the form of heat
energy. In order to overcome the rate of reflection, current research aims in
synthesis of erbium oxide nanosheets using electrospinning deposition technique
for varying deposition timings such as 1, 1.5 and 2 hours. The coated solar
cells K1, K1.5 and K2 exert coating thickness of 15.94, 20.34 and 23.88 μm
respectively. The K1.5 solar cell exhibits greatest optical rate of
transmittance (90.12%) and lowest rate of reflection, which is comparatively
greater than uncoated samples. The EPC of the sample was observed to be (18.79%)
under a controlled environment illuminated by a neodymium radiated lamp. Based
on the results and discussions, it is evident that the synthesized
Er2O3 helps to control reflection losses, which
eventually leads to increase in EPC.

Published: February 2024

Aerodynamic resistance stands as a pivotal factor impacting the performance of
race cars, creating significant impedance to their movement. Diverse strategies
exist to alleviate this resistance, including the integration of aerodynamic
elements and refinement of the vehicle's body contours. By emphasizing drag
reduction without altering the powertrain, race car designs can effectively
curtail drag. This study centers on the exhaustive examination, analysis, and
experimentation with a model representing a Formula Student (FS) car, with the
primary objective of augmenting its aerodynamic efficiency for motorsport
applications. In compliance with the SAEINDIA Supra regulations, a meticulously
crafted CAD model of the formula car is developed. After this, the model
undergoes simulation utilizing computational fluid dynamics (CFD) tools,
facilitating the identification of turbulent zones and areas of enhanced drag. A
scaled-down 3D printed model is then employed for comparative analysis within a
wind tunnel. The insights garnered from these experiments enable iterative
modifications to the initial model based on the obtained results. Further CFD
analyses are conducted on the refined iteration, initiating an iterative
enhancement process aimed at optimizing the vehicle's aerodynamic performance.
The culmination of this comprehensive process involves the development,
analysis, and testing of a prototype, showcasing a notable 28% enhancement in
aerodynamic performance. This accomplishment underscores the effectiveness of
the iterative refinement methodology in elevating the overall aerodynamics of
the vehicle. However, it is crucial to acknowledge that implementing such
designs may pose challenges for manufacturers, although not insurmountable ones.
Additionally, it's important to note that outcomes from CFD simulations and wind
tunnel tests have a 3% deviation in results, that can be influenced by factors
like surface finish and boundary conditions, leading to potential variations.
Acknowledging these limitations contributes to a comprehensive comprehension of
the research's scope and potential sources of variability in the results
attained.

Published: February 2024

Solar energy, which has always been at the forefront, has discovered numerous
uses in a variety of fields. One of the key targets of scientists and producers
in the twenty-first decade is sustainable solar energy collecting. The
maximization of solar energy is totally dependent on the radiation absorbed by
the photovoltaic panels. Radiation is observed using numerous equipment and
calculated using diverse methods. If the device is to be totally reliant on
solar energy, it must be calculated far ahead. It is difficult to work because
solar radiation is affected by various factors, including region as well as
seasonality. In forecast scenarios, Artificial Neural Networks (ANN) is a
popular approach among scientists. Therefore, this research provides a technique
for estimating solar radiation that makes use of back-propagation algorithms.
The data of 17 stations in Tamil Nadu, India, were acquired for analysis and
split into three clusters: training, validation, and testing. This research is
focused on nine input variables and one outcome variable. Solar radiation is
estimated via feed-forward back-propagation in this case. The presented approach
is ascertained for training techniques such as Levenberg Marquardt (LM),
Bayesian-Regularization (BR), as well as Scaled Conjugate Gradient (SCG). In all
three scenarios, the resulting statistical error values and regression values
prove the adequacy of the presented approach. The Root Mean Square Error (RMSE)
for the BR approach is found to be the lowest, with a value of 0.0013. Also,
from all statistical error and regression values, the training approach BR
produces the best value than LM and SCG training approaches.

Published: February 2024

The limitations of commonly used materials such as steel in withstanding high
temperatures led to exploring alternative alloys. For instance, Inconel 825 is a
nickel-based alloy known for its exceptional corrosion resistance. Thus, the
Inconel 825 is used in various applications, including aerospace, marine
propulsion, and missiles. Though it has many advantages, machining this alloy at
high temperatures could be challenging due to its inadequate heat conductivity,
increased strain hardening propensity, and extreme dynamic shear strength. The
resultant hardened chips generated during high-speed machining exhibit elevated
temperatures, leading to tool wear and surface damage, extending into the
subsurface. This work investigated the influence of varying process settings on
the machinability of Inconel 825 metal, using both uncoated and coated tools.
Optimal surface roughness (Ra) machining conditions were found by considering
factors such as depth of cut, cutting speed, feed rate, and other parameters.
The major objective of the present work was to enhance the machinability of
Inconel 825 by considering the surface finish values. The results revealed that
the favorable surface roughness (SR) values for machining Inconel 825 in an
automated lathe were attained under lubricated coated conditions with a cutting
speed of 100 m/min, feed rate of 0.06 mm/rev, and cutting depth of 0.7 mm.

The objective of this study was to quantify the field performance of passenger
vehicle event data recorders (EDRs) in recording data into non-volatile memory
at the 8 km/h delta-v (Δv) trigger threshold specified by Title
49, Part 563 of the Code of Federal Regulations (Part 563). Part 563 applies to
passenger vehicles manufactured on or after September 1, 2012. The trigger
threshold is distinct from the threshold required to deploy an airbag. Events
meeting the trigger threshold will cause data to be preserved on the EDR even if
airbags are not deployed. This is the first study to quantify EDR trigger
threshold performance. This data is valuable in the evaluation of sub-airbag
deployment crashes. The study was accomplished via analysis of EDR and
reconstructed Δv data from 3,960 cases in the Crash
Investigation Sampling System (CISS) database maintained by the National Highway
Traffic Safety Administration (NHTSA). The binary presence or non-presence of an
event on the EDRs of vehicles exposed to a collision was compared to the CISS
reconstructed Δv for each vehicle. Logistic regression models
were developed to predict the probability of an event present on the EDR at the
trigger threshold. We found that vehicles manufactured by Toyota had lower
Δv thresholds compared to other manufacturers. For Toyota
manufactured vehicles, the probability of an EDR event at 8 km/h ranged from 87%
to 99%. EDR event probabilities for non-Toyota vehicles in vehicle-to-vehicle
collisions ranged from 58% to 93% for Part 563 compliant vehicles and 33% to 83%
for pre-Part 563 vehicles. The persistence of EDR events in memory was analyzed
using the number of ignition cycles present between events and imaging of the
EDR, finding average duration of 3,595 ignition cycles for pre-existing EDR
events unrelated to the CISS case.

ANALISIS YURIDIS RESTORATIVE JUSTICE DALAM KEPASTIAN HUKUM TERHADAP ANAK PELAKU TINDAK PIDANA
Authors: Melati Annisa Fitri Arrum , Syawaludin Syawaludin , Utoyo Marsudi
Published: February 2024

Abstract

Restorative Justice is an approach to justice that focuses on the needs of victims and perpetrators of crime, and involves community participation, rather than implementing the principle of punishing perpetrators accompanied by the judge's considerations. Crimes committed by children are basically inseparable from various life pressures, both economic and social. As a result, quite a few children become perpetrators of crimes or crimes. This research uses a Normative Juridical research method using a statutory approach, a case approach and a conceptual approach. For children's cases, diversion must be carried out in every examination of children's cases from investigation, prosecution to examination at trial, taking into account: the category of crime, the age of the child, the results of social research from the father, the support of the family and community environment. The judge's authority is to examine and decide on children's cases at the first level with a single judge and as a facilitator in diversion. The advice that can be given is that children who commit crimes must still receive protection in the juvenile criminal justice system. One of them is implementing restorative justice using the diversion method, and judges who have the authority to examine and decide on children's cases must be proactive in encouraging restorative justice using the diversion method.

Emerging research suggests that the global prevalence of youth mental distress has increased considerably during COVID-19 pandemic. Mental health among Kenyan Youth had already been deteriorating prior to the pandemic. This is largely attributed to academic pressure, financial constraints, interpersonal relations, and adjustment to university environment. Negative coping strategies, such as alcohol and substance use, adversely affect academic advancement, and mostly lead to students drop out. It is often unclear what preventive measures and interventions might be effective for university students. This study (a) examines the relationship among mental distress and undergraduate students’ academic achievement and (b) assesses the role of coping strategies in this relationship. The study adopted a descriptive survey and correlational research design. Participants were 277 students (Females = 52%, Males = 48%) randomly sampled from four universities in Kenya (two public and two private). Ethical approval for the study was obtained from the relevant authorities. The majority (91.3%) were aged above 18 years. Self-report Depression, Anxiety and Stress Scale-21 Items (DASS-21) and Stress Coping Strategies Questionnaire (SCSQ) were adopted to measure mental health and coping strategies, respectively. Students indicated their Grade Point Average (GPA) as shown in the university system. Findings indicated that a significant negative correlation was established between overall mental distress and GPA (r = - .15, p = .01). Unexpectedly, coping strategies did not mediate the association between mental distress and academic achievement as measured by the GPA. The findings are discussed in relation to previous studies and implications for university education.

The cytological examination is a rapid and minimally invasive procedure that allows the evaluation of numerous organs. This paper aims to analyze retrospectively the cytological diagnoses of canine hematopoietic tissues made at a school hospital in the state of Minas Gerais. Between January 2009 and July 2012, 225 lymph node and spleen exams and 163 bone marrow exams were performed. Non-neoplastic abnormalities were observed in 43% of lymph node samples and in 9% of bone marrow samples, and there was an association with leishmaniasis in 12.6% and 20.9% of these, respectively. Lymphomas were diagnosed in 23.1% lymph nodes samples, and leukemias were diagnosed in 8.6% of bone marrow samples. The cytological examination of these organs proved to be of great assistance to clinicians in the diagnosis of hemoparasites, staging cancer and research for primary or metastatic neoplasms.

The Amazon tree boa is a non-venomous aglyphous snake from the Boidae family that can reach a length of just over two meters. Osteosarcomas are malignant tumors from mesenchymal origin, which may contain connective tissue, cartilage, osteoid and immature bone. An Amazon tree boa was brought in for withdrawal of a neoformation in the oral cavity originating in the left maxilla. After radiographic evaluation and confirmation of the presence of a radiopaque structure, an anesthetic protocol with midazolam associated to ketamine was instituted to restrain the animal. Induction and maintenance was introduced with isoflurane diluted in 100% oxygen for surgical removal of the structure. Tissue fragments were processed and evaluated histologically. Neoplastic proliferation of osteoblasts and rare mitotic figures were detected, allowing the clinicopathological diagnosis of osteosarcoma.

Authors: Ersözlü Fatma
Published: February 2024

Yeremya peygamber, Babil sürgünü döneminde Yahuda topraklarında yaşamış ve sürgüne şahit olmuştur. Yeremya, peygamberliği süresince Yahve’nin Musa ile yaptığı Sina ahdinden uzaklaşmış olan İsrailoğullarını, ahit şartlarına uymaya çağırmış ve bu isyanlarında devam etmeleri halinde yaklaşan sonu haber vermiştir. Tanah’ta anlatılan İsrailoğullarının tarihi; Yahve’ye isyan, ilahî gazap, yıkım, sürgün ve dönüş üzerine bir döngü halinde tekrarlamaktadır. Yeremya döneminde yaşananlar ile ilgili peygamberin bildirisi de bu sıralamayı takip etmiştir.

Babil sürgününe gidiş sürecini anlatan Yeremya Kitabı’nda, Yahve’nin On Emir’de bildirdiği “Benim önümde başka ilahlarınız olmayacak” emrine itaat etmeyen ve başka milletlerin ilahlarına yönelen halkı bekleyen yıkım ve sürgün anlatılmaktadır. Yeremya, belirli bir zaman süreceğini bildirdiği sürgünden sonra Yahve’nin İsrailoğullarına duyduğu sevgi nedeniyle yeniden onları Kudüs’te toplayacağı müjdesini vermektedir. Bu makalede, Yeremya Kitabı’nın konu başlıkları, teması ve Tanah’ta özellikle bu kitapta yer alan kelimeler üzerinden tahlil edilecektir.
Assessing the Impact of Climate Change on Characteristics of Tropical Cyclones in Houston, Texas
Authors: Zeng Sophie
Published: February 2024

The objective of this research is to utilize a computational model for assessing the impact ofclimate change on tropical cyclones in the Houston, Texas area. In recent years, it has beenobserved that tropical cyclones have become more destructive, increasing in intensity andfrequency. The current body of knowledge on tropical cyclones has indicated the significant rolethat climate change plays in the worsening of tropical cyclones. This research focused onstudying the characteristics of tropical cyclones potentially affected by climate change in theHouston, Texas area, stemming from the researcher’s firsthand experience of Hurricane Harveywhich occurred in August of 2017. Nine global climate models were studied and incorporatedinto a MATLAB computational program in this research to generate a total of 9,000 synthetictropical cyclones with and without climate change for comparison purposes. The variouscharacteristics of tropical cyclones were analyzed based on the output of the MATLAB program.A comparison of these characteristics yielded the conclusion that climate change plays a key rolein increasing the likelihood of destructive characteristics of tropical cyclones. Therefore, it islikely that future tropical cyclones in the Houston, Texas area will demonstrate an increased riskseverity, causing more harm to people and more damage to local society. It is highlyrecommended that future research should focus on mitigation strategies for the Houston, Texasarea to reduce the consequence of tropical cyclones and prevent the situation of HurricaneHarvey from reoccurring.
Using Different Machine Learning Algorithms to Predict the Prices of Flight Tickets
Authors: Bollack Jeremy Rohan , Vincent Joseph Anthony
Published: February 2024

The rising prices of flight tickets and the lack of transparency in the dynamic pricing strategies of airlines have caused many consumers to wonder, what factors actually determine these prices. In order to investigate this question, a large dataset of flight ticket bookings that includes the most price-defining variables was acquired. This data was preprocessed using discretization, normalization, and principal component analysis. This preprocessed data was then used to train 5 different Machine Learning algorithms: Linear Regression, DecisionTree, Ridge Regression, RandomForest, and SVR. The training of the RandomForest and SVR models was not possible due to runtime errors, however, the other models trained as expected. All models performed well, with the Linear Regression and Ridge Regression performing identically. Overall, the DecisionTree model performed the best at predicting the prices of flights, and by adjusting hyperparameters the performance could be further increased. The investigation could be continued by using a larger dataset to investigate how the model performs with more variables and under broader conditions. Additionally, the model could be reappropriated to make a user-friendly flight price prediction tool that helps consumers with their purchasing decisions.

As AI technology continues to advance rapidly, it is essential to address the environmental concerns associated with the increasing carbon emissions and their contribution to global warming. The expanding AI industry requires significant computing power, making it a potential major contributor to carbon emissions in the future. Unfortunately, our current understanding of AI models is very limited. We conducted a comprehensive analysis involving 12 distinct AI models, encompassing object detection, translation, and text-to-image generation tasks. Our findings revealed that smaller AI models can achieve equal or even better results compared to larger models while offering a significant reduction of carbon emissions. This highlights the potential for environmental savings by prioritizing smaller models. These findings underscore the importance of considering the environmental impact of AI models and encourage the adoption of strategies such as using smaller models and optimizing workload schedules to reduce carbon emissions. By prioritizing sustainability in AI development and deployment, we can work towards a greener and more sustainable future.
