Risk-Based Tax Audits in India and Evolution to Risk Management
Authors: Sharma Saksham
Published: December 2022

Abstract: Today's tax administrations lay increased emphasis on self-assessment and voluntary compliance, and they are moving the emphasis of tax enforcement from risk assessment and management to risk assessment and management. This is because (1) it would be inefficient to regularly audit low-risk, complying individuals and (2) no revenue administration can realistically monitor and inspect every taxpayer. This comprehensive and collaborative strategy aims to promote taxpayer compliance by systematically addressing compliance challenges as a component of long-term strategic planning. Indian tax administration (direct taxes) has adopted risk-based auditing utilising a computer-assisted scrutiny method gradually but progressively (CASS). Despite the establishment of CASS, human selection of tax audits has persisted. The revenue administration is a crucial link between the government and its people. Consequently, a trustworthy tax system is necessary for functional governance. Consequently, legislators are just now realising the need to establish legislation that simultaneously encourages corporate development and ensures complete, voluntary tax compliance. At this time, it is neither desired nor feasible to perform a comprehensive audit of every single taxpayer. Consequently, good compliance management is vital for tax administration. To encourage voluntary compliance, i.e., when taxpayers voluntarily comply with their tax duties without interference from tax authorities, it is essential to establish innovative auditing strategies based on risk management. Audits depend primarily on a systematic technique of choosing auditees that identifies and prioritises taxpayers who represent the greatest threat to the government in order to maximise their efficacy. This aids in fostering a more willing attitude of compliance. As was also recently observed, when the government is unable to properly combat tax evaders, it may lead to a range of concerns and problems. In view of the significance of tax compliance, I want to study methods to make it even more efficient. This article examines riskbased audits for tax compliance, concentrating on their definitions, the significance of key terminology, their application, and their effectiveness. In the essay's meatier middle portion, I will argue why such a system would be advantageous for emerging nations such as India, using specific examples from countries such as the Netherlands. In addition, a practical model may be created by researching the tax compliance rules of various nations and then constructing a risk management-based system.

A Review of Language Learning Applications
Authors: Rugge Shrishail , Metri Veer , Satpute Sujay , Nule Prathmesh , Devmore Mrs. A. P.
Published: December 2022

Abstract: Language learning applications have the potential to transform the way languages are learned. This study examined the most popular commercially available language learning applications and evaluated them according to a wide range of criteria. The study found out that no application exists in the market that can teach the Indians or anyone in the world the desired Indian Regional Languages. Three major trends were found in the applications that teach languages to the users: first, apps tend to teach vocabulary in isolated units rather than in relevant contexts; second, apps minimally adapt to suit the skill sets of individual learners; and third, apps rarely offer explanatory corrective feedback to learners. Despite a pedagogical shift toward more communicative approaches to language learning, these apps are behaviorist in nature. Also we aim to create an application that will specifically teach Indian languages to the users in a more effective way replacing the old traditional way of learning

Published: December 2022

Abstract: The purpose of this report is to identify /observe and determine the pattern of velocity profile and pressure distribution by using CFD simulation program after the 3D design and modeling of the pump is made using Vista CPD. We have also created a Solid model using Fusion 360 to get a clear idea of Centrifugal pump design. Basically, this report revolves around the idea of investigating the effect and distribution of velocity profile and pressure within a pump having the following specification, Head = 20 m, Flow rate = 100 m3 /hr, and RPM = 2000. 3D Navier–Stokes equations were solved using ANSYS CFX. The standard k −εturbulence model was chosen for the turbulence model. From the design point of view, we have studied the effects of different parameters like rotational speed, volume flow rate etc on the impeller and volute. From the simulation results it was observed that the pressure increases gradually from impeller inlet to outlet. The static pressure on the pressure side is evidently larger than that on the suction side at the same impeller radius. In addition to this, it was observed that the velocity increases from the impeller inlet until it enters the volute casing. It then drops to a minimum value at the outlet region.

Published: December 2022

Abstract: Construction projects execution has changed drastically more from last decades. In execution of project there are many departments working for successful project execution. These all departments need to cope up with the changes occurring in industry. One of the departments helping for execution of project is store. To execute project successfully store department role is very important. In traditional system, store is only considered as the storage place. Small or medium scale construction organization does not use the store as effective department for in time project delivery. Store management can support to Just in time concept and helpful for inventory control and in time project completion. Store management increases the efficiency of work and helps for smooth working. It is observed that the activity going on site are delayed majorly due to unavailability of material. Poor store management leads to purchase of material with high rate as emergency from local vendors to avoid delay. Sometimes the material within the stor due to poor store management gets wasted and to lead cost for project. This paper is to study effective store management which helps to JIT approach causing minimum inventory cost and wastage of material.

Authors: Aravind V. , Ranjith V.
Published: December 2022

Abstract: In this research, eggshell powder (ESP) was used as a partial substitute for cement in concrete to decrease the usage of cement in concrete production. The main objective of the study was to determine the workability and reinforcing properties including compression, tensile and flexural strength of concrete using various percentages (0, 10, 20,&10) of ESP by weight instead of cement. A total of 38 concrete samples were cast (12 cubic meters, 12 cylinders and 12 prisms) with a target strength of 28 N/mm2. The compressive strength of a cube sample (150 × 150 × 150 mm) was tested after 7, and 28 days, while tensile strength were also measured for 7 days and 28 days using a cylindrical specimen (200 × 100 mm). The bending strength of the specimen (100 x 100 x 500 mm), cast during 7, and 28 days of curing. The test results showed that during the. With ESP 20%, tensile strength increased by 30%, and a maximum strength of 20% was obtained using ESP 20% during 28-day cure. As the percentage of ESP increases, the workability of fresh concrete decreases. ESP is used in concrete to enhance the power of a concert. Natural aggregates are becoming scarce and their production and shipments is also becoming more difficult. The main objective of this study is to identify alternative source of good quality aggregates which is depleting very fast rate due to the fast pace of construction activities in India and to improve the workability and durability of concrete. Use of steel slag as a waste industrial which is the by-Product of iron and steel production provides great opportunity to utilize it as an alternate to normally available coarse aggregates. In this study concrete of M30grade for a w/c ratio of 0.45 respectively for the replacement of 10%,20% and 30% of coarse aggregates by steel slag which is produced as a waste material in steel industry and has a negative impact on environment when disposed. The investigation reveals that the steel slag could be utilized as coarse aggregate in all the concrete applications and shows a considerable improvement in the compressive strength of concrete over the control mixes by 7 to 8%. Results show that the concrete incorporating steel slag has higher compressive strength and an increase in density and stability was clearly observed in the specimens replaced with steel slag as coarse aggregate

Published: December 2022

Abstract: Two-dimensional matrix barcodes called "Quick Response" (QR) are used. It must store much information compared to one-dimensional barcodes, and it must be decrypted quickly using any handheld device, including a smartphone. When creating two-dimensional matrix codes, these two considerations are taken into account. The possibility of security becomes a significant factor when a bar code contains sensitive information or private data Users are unsure of whether a QR code will connect them to reliable information or a malicious website because QR codes are simply square bar codes with a distinctive design. Recently, QR codes have been used in numerous application fields, and their use is growing quickly. As a result, more individuals are becoming acclimated to this technology and using it properly. Due to the QR code's increasing popularity as more people use smartphones, it is swiftly acquiring universal acceptance. Given their broad acceptance, the security aspect of QR codes, such as data leakage and data tampering, is critical. The paper offers a comprehensive overview of QR codes and their applications.

Published: December 2022

bstract: The Completely Automated Public Turing Test to Tell Computers and Humans Apart (CAPTCHA) is a crucial humanmachine distinguishing technique for websites to fend against automated attacks from malicious software. Studies on CAPTCHA recognition have the potential to uncover security flaws, improve CAPTCHA technology, and even advance handwriting and license plate recognition. However, the whole objective of the CAPTCHAs may be bypassed using the principles of deep learning and computer vision. Convolutional neural networks (CNN) may be used to automatically pass this exam. A CNN is a deep learning algorithm that uses an image as input before giving distinct characteristics in the picture a value that further aids in differentiating one feature from another. Its major objective is to convert the pictures into a more simple form while retaining elements that are crucial for obtaining an optimum forecast.

Published: December 2022

Abstract: Over the last several years, deep learning has seen a considerable increase in its usage and applications. One of the most basic algorithms in either machine learning or deep learning is image classification. Numerous businesses, like Microsoft and Google, use deep learning in their products, including search engines, Google Lenses, and other areas of technology. The enhancements and technical advancements in this area specifically serve to enhance the model's performance. The categorization of numerous photographs into two different groups is the focus of this study. In this study, the data is initially preprocessed to ensure that it can be easily inserted into the deep learning neural network model. Without using any pre-existing deep learning frameworks like Tensor Flow, the architecture and neural networks needed for this project are designed from the ground up. In this study, we essentially use deep learning neural networks that were built from scratch to attempt to discriminate between a cat and a dog. Each and every cost and activation function is calculated by hand. We build a two-layer neural network to divide the photos into two groups that meet our needs. For the training data, the developed model's accuracy is 98%, while for the test data, it is over 80%. If the data is suitably pre-processed, this deep learning model may also be used to classify other images.

Abstract: All industrial civilizations share the fundamental trait of widespread wage employment. Workers/employees and employers/management are two separate categories of people who are looking for wage employment, respectively. Known variously as labour-management relations, labour relations, industrial relations, or employer-employee relations, these two groups' relationships are structured. With the exception of the first, these definitions indicate that the relations are at minimum inclusive on the part of the employees. In regards to all problems that concern its members, the labour union negotiates with employers and management. Consequently, the two groups' relationships are structured.

Published: December 2022

A noção de “complexo” nos estudos urbanos e regionais brasileiros foi relevante no contexto agroexportador e industrial nos séculos XIX e XX, respectivamente, ao revelar arranjos sociais da urbanização nesses momentos históricos. Na interpretação das transformações urbanas contemporâneas, sustenta-se que a noção do “complexo imobiliário-financeiro”, concebida no Norte Global, deve considerar as especificidades de cada formação social particular. Este trabalho busca compreender a formação e a atuação de um complexo em decorrência do desenvolvimento dos Fundos de Investimento Imobiliário (FIIs). Investigam-se os principais marcos institucionais do instrumento e os agentes envolvidos em seus desenhos, de modo a problematizar as essências constitutivas do complexo que suporta o instrumento e as transformações no espaço. A pesquisa identifica o domínio das instituições financeiras nacionais, em articulação com as finanças globais, sobre a indústria de FIIs e propõe a categoria de “complexo financeiro-imobiliário”, a qual indica a subordinação dos interesses do setor imobiliário aos financeiros.
The voices of the tenement operators
Authors: Lui Marcos Venancio Cavalcanti de Albuquerque , Cymbalista Renato
Published: December 2022

Tenements have been a housing option for the poor in downtown São Paulo since the 1870s. Studies on tenements in São Paulo have been conducted for more than a century, although the major subject missing from the literature has been the tenement intermediaries or operators, the articulating agent of the entire scheme. The text is based on six interviews conducted with tenement landlords and intermediaries in the central region of São Paulo. Through discourse analysis 6 analytical categories have been listed: 1. The beginning of the activity: in which the insertion of the operator into the ecosystem of the tenements is narrated, and sometimes the transformation of properties into tenements; 2. Selection and contracts: how residents move in and the rental documents and agreements; 3. Caretaking: the maintenance of each tenement, habitability; 4. Coexistence: the daily relationship between tenants and landlords and intermediaries; 5. Rates and earnings: costs and income obtained; 6. Future and life projects: how the operators visualize their future in relation to the tenement(s), expansion, sale and even leaving the business. Rather than the tenement operator being described generically, with negative attributes, common figures emerge, who are mostly poorly capitalized and who strive to obtain a slight social upward mobility or to interrupt processes of deterioration.
As vozes dos operadores de cortiços

Published: December 2022

Os cortiços são uma opção de moradia dos pobres no centro de São Paulo desde a década de 1870. Estudos sobre cortiços na cidade já são feitos há mais de um século, mas o grande sujeito ausente da literatura são os intermediários ou operadores de cortiços, o agente articulador de todo o esquema. O texto é construído a partir de sete entrevistas realizadas com operadores proprietários e intermediários de cortiços da região central da capital paulista. Pela análise do discurso, elencamos seis categorias analíticas: 1) Início da atividade: inserção do operador no ecossistema dos cortiços e, por vezes, transformação de imóveis em cortiços; 2) Seleção e contratos: entrada de moradores, documentos de locação e acordos; 3) Zeladoria: manutenção de cada cortiço e habitabilidade; 4) Convivência: relação cotidiana dos inquilinos com os proprietários e intermediários; 5) Valores e ganhos: custos e receitas; 6) Futuro e projetos de vida: visualização do operador sobre o futuro relacionado ao(s) cortiço(s), expansão, venda e até saída do negócio. No lugar do operador de cortiço descrito de forma genérica com atributos negativos, emergem figuras comuns, em sua maioria, pouco capitalizadas e que se esforçam para obter uma pequena ascensão social ou interromper processos de decadência.

Published: December 2022

Na contemporaneidade as práticas de governança urbana, principalmente na América Latina, demonstram ações de neoliberalização. São organizadas por meio de acordos espaciais e institucionais em favor do mercado. A dinâmica imobiliária e os impactos das grandes intervenções neoliberais são notórios na lógica de (re)produção do espaço urbano. O objetivo deste artigo é investigar as relações entre os Grandes Projetos Urbanos (GPUs), as novas coalizões e os arranjos institucionais para realização do megaevento esportivo Pan 2019, em Lima e Callao, no Peru.  São destacadas determinadas orientações que compõem a pauta exercida pelo Estado para a governança urbana, principalmente no que se refere à formação de Parcerias Público-Privadas (PPPs) e o aumento da desregulamentação e da flexibilização do Estado. Por meio do aporte de bibliografias internacionais e locais, busca-se demonstrar a lógica neoliberal e urbana que embasa o processo. Como resultado, observa-se que esse modelo resulta em uma urbanização voltada para as necessidades mercadológicas locais.

Published: December 2022

Gold nanoparticles (GNPs) are promising materials for many
bioapplications. However, upon contacting with biological media, GNPs
undergo changes. The interaction with proteins results in the so-called
protein corona (PC) around GNPs, leading to the new bioidentity and
optical properties. Understanding the mechanisms of PC formation and its
functions can help us to utilise its benefits and avoid its drawbacks.
To date, most of the previous works aimed to understand the mechanisms
governing PC formation and focused on the spherical nanoparticles
although non-spherical nanoparticles are designed for a wide range of
applications in biosensing. In this work, we investigated the
differences in PC formation on spherical and anisotropic GNPs (nanostars
in particular) from the joint experimental (extinction spectroscopy,
zeta potential and surface enhanced Raman scattering [SERS]) and
computational methods (the finite element method and molecular dynamics
[MD] simulations). We discovered that protein does not fully cover
the surface of anisotropic nanoparticles, leaving SERS hot-spots at the
tips and high curvature edges “available” for analyte binding (no SERS
signal after pre-incubation with protein) while providing
protein-induced stabilization (indicated by extinction spectroscopy) of
the GNPs by providing a protein layer around the particle’s core. The
findings are confirmed from our MD simulations, the adsorption energy
significantly decreases with the increased radius of curvature, so that
tips (adsorption energy: 2762.334 kJ/mol) would be the least
preferential binding site compared to core (adsorption energy: 11819.263
kJ/mol). These observations will help the development of new
nanostructures with improved sensing and targeting ability.

MDCK is the main cell line for influenza vaccine production. Previous
studies have reported that MDCK cells have tumorigenic ability in nude
mice. Although complete cell lysis can be ensured during vaccine
production, more caution is needed in vaccine production for human use.
Therefore, the use of gene editing technology to establish cells that
cannot form tumors can significantly improve the biosafety of influenza
vaccines. The key is to understand the genes and molecular mechanisms
that affect the tumorigenic ability of MDCK cells. However, our
understanding is still superficial. We previously obtained a cell line
CL23 with significantly reduced cell proliferation, migration, and
invasion through a monoclonal cell screen, and subsequent tumor-bearing
experiments in nude mice showed no tumorigenic cells. DIA proteomics
method was used to compare the protein expression differences between
wild-type (M60) and non-tumorigenic (CL23) cells, and to explore the
genes related to tumorigenesis in MDCK cells. The differentially
expressed proteins were verified at the mRNA level by RT-qPCR, and
several genes involved in cell tumorigenesis were preliminarily
screened. Western blot further confirmed that the expression of related
proteins was significantly reduced in non-tumorigenic cells. Inhibition
of CDC20 expression by RNAi significantly reduced the proliferation and
migration of MDCK cells and increased the proliferation of influenza
virus. Therefore, CDC20 is an effective target gene for inhibiting the
tumorigenicity of MDCK cells. This study lays the foundation for the
establishment of target gene screening in genetically engineered
non-tumorigenic MDCK cell lines.
Intermodel spread in Walker circulation responses linked to spread in moist stability and radiation responses
Authors: Duffy Margaret L , O'Gorman Paul A
Published: December 2022

The response of the Pacific Walker circulation (WC) to long-term warming
remains uncertain. Here, we diagnose contributions to the WC response in
comprehensive and idealized general circulation model (GCM) simulations.
We find that the spread in WC response is substantial across both the
Coupled Model Intercomparison Project (CMIP6) and the Atmospheric Model
Intercomparison Project (AMIP) models, implicating differences in
atmospheric models in the spread in projected WC strength. Using a moist
static energy (MSE) budget, we evaluate the contributions to changes in
the WC strength related to changes in gross moist stability (GMS),
horizontal MSE advection, radiation, and surface fluxes. We find that
the multimodel mean WC weakening is mostly related to changes in GMS and
radiation. Furthermore, the spread in WC response is related to
the spread in GMS and radiation responses. The GMS response is
potentially sensitive to parameterized convective entrainment which can
affect lapse rates and the depth of convection. We thus investigate the
role of entrainment in setting the GMS response by varying the
entrainment rate in an idealized GCM. The idealized GCM is run with a
simplified Betts-Miller convection scheme, modified to represent
entrainment. The weakening of the WC with warming in the idealized GCM
is dampened when higher entrainment rates are used. However, the spread
in GMS responses due to differing entrainment rates is much smaller than
the spread in GMS responses across CMIP6 models. Therefore, further work
is needed to understand the large spread in GMS responses across CMIP6
and AMIP models.
Thermospheric Densities as Revealed by Concurrent 2 MAVEN, Swarm-C, and GOES Observations
Authors: Gasperini Federico , Hughes J , Thiemann E M B
Published: December 2022

The responses of Earth’s and Mars’ thermospheric densities to
quasi-periodic solar rotation variations in flux were measured
contemporaneously by the MAVEN, GOES, and Swarm-C satellites. While
large solar rotation variability is found in both planetary
thermospheres, correlation analyses performed on 6+ years of data reveal
that, independently of flux level, Earth’s daytime density response is
about 10-50% larger than Mars’ at a similar density level. Important
altitude dependencies in the sensitivities are found in the Martian
thermosphere, while the terrestrial thermosphere is shown to exhibit
only small (±5%) day/night and latitude variations in the response.
Detailed analyses focused on correlative periods in 2015-2016 and 2020
indicate important solar cycle effects in the sensitivities of both
planetary thermospheres, with increased slopes with low solar flux.
These results provide important new insights into processes relevant to
the interpretation of the sources of short-term density variability in
Mars’ and Earth’s thermospheres associated with solar drivers and point
to the need for targeted modeling efforts along with dedicated data
analyses to help resolve current unknowns in thermal balance processes.

Kamodo is an official NASA open source python software package that
functionalizes diverse datasets from models and observations in a
consistent way, enabling advanced scientific analysis and visualization
with simplistic syntax. Here we demonstrate this ability using several
ITM models available through the Community Coordinated Modeling Center
(CCMC). Users can now interact directly with model outputs, and
satellites can be virtually flown through model output to allow many
types of model/model and data/model comparisons. We will also provide
information about significant updates and improvements to Kamodo and
future plans.

The core of Kamodo is supported by Ensemble Government Services and is

Seismic velocity structure of the easternmost segment of the Gofar transform fault, East Pacific Rise
Authors: Estève Clément , Liu Yajing , Gong Jianhua , Fan Wenyuan
Published: December 2022

The fast-slipping (~ 14 cm/yr) Gofar transform fault
(GTF) East Pacific Rise has three active segments G1 to G3 from east to
west. These fault segments produce large earthquakes (MW
~ 6.0) quasi-periodically every five to six years
(Figure 1). Interestingly, large earthquakes rupture the same 20-km long
fault patches separated by a ~ 10-km rupture barrier
zone, implying along-strike variations in fault zone material properties
(McGuire et al. 2012). This further suggests that rupture patches and
barrier zones remain stable over multiple seismic cycles. Here, we
jointly invert P- and S-wave travel times, recorded at an
ocean-bottom-seismometer (OBS) experiment along G1 between January 2019
and February 2020, to determine the 3-D seismic velocity structure of
the area and relocate the local earthquakes. Our velocity models reveal
a large low-velocity anomaly extending through the entire oceanic crust
along G1 with some along-strike variations. We identify a 10 km-long
rupture barrier zone, which is interpreted to be highly fractured with
enhanced fluid circulation. We further suggest that the observed deep
seismicity underlying the rupture barrier zone may indicate sea-water
infiltration.  Lastly, we apply the same approach to the westernmost
segment of the GTF and observe some similarities and differences between
the two fault zone seismic velocity structures.

Dynamical heating and cooling are prominent features of planetary
atmospheres resulting in thermospheric structures on Venus, Earth and
Mars. The purpose of this study is to determine the location and
amplitude of localized heating regions in the Martian thermosphere,
confirm that they occur in regions of wind convergence, and to compare
the observed dynamical heating with that predicted by a global
thermospheric model. This investigation uses several years of data from
the NASA Mars Atmosphere and Volatile EvolutioN (MAVEN) mission
including observations made by the Neutral Gas and Ion Mass Spectrometer
(NGIMS) as well as the Extreme Ultraviolet Monitor (EUVM). Specifically,
the analysis focuses on several years of horizontal wind, temperature,
and composition data. EUVM measurements provide a solar forcing context
for the neutral thermosphere datasets and aid in the statistical
analysis. Statistical results are compared with two versions of the Mars
Global Ionosphere Thermosphere (M-GITM) global circulation model; one
that that includes gravity wave parametrization and a version without
gravity wave effects. Data analysis indicates that heating features
exists around 2-3 and 17-18 local solar time. These locations coincide
with regions of converging winds and are in better agreement with M GITM
when gravity wave parametrization is included in the model. A migrating
oscillation in the observed wind field also results in convergence and a
density enhancement near 15 local time. While a similar oscillation is
reproduced by the model, the amplitude is much lower than observed and
may be a result of modeled zonal winds that are too low.

The current paper demonstrates the design parameters and tolerances for a horizontal axis wind turbine. Here we have adopted one of the DOE (design of experiment) method namely Taguchi method, a traditional approach for designing a robust wind turbine. For optimization purpose, the evaluation and estimation of various problems i.e; constrained as well as unconstrained have been done using Taguchi method. For the derivation of design parameters lift coefficient (CL), drag coefficient (CD) and power coefficient (CP) the L-9 Orthogonal array (OA) comprising of 4 parameters each with three levels (NACA aerofoil type, Mach number, Reynolds number and angle of attack) are considered. Open source Q-Blade designing software is used for determining power, lift and drag coefficients of the wind turbine. The combination of GRA and orthogonal arrays are used for attaining the optimized parameters. In this paper an investigation has been carried out on the specific NACA aerofoils 4412, 4712 and 4421. Among all the aerofoils NACA 4712 has showed the impressive results in terms of maximum lift coefficient of 0.9491and minimum drag coefficient of 0.02601. Also from signal to noise plots it can be inferred that the most influenced parameter for CL and CD is Mach number and Aerofoil for CP.

Transesterification of expired vegetable oils is possible by heating them with a significant amount of methanol and an acidic or basic catalyst to improve the reaction rate and yield. In this study 4 samples have been selected, including 4 types of vegetable oils, namely: soybean, sunflower, rapeseed, pumpkin seed. The operative conditions of the reaction were reaction time (4 h), catalyst concentration (1 w/wt %), and oil-to-methanol molar ratio (6:1). The parameters studied to compare the quality of biodiesel obtained by each type of compound are: yield, pH, density, acid value. The results shows that The pumpkin seed have a positive effect on increasing the yield of Soybean biodiesels as well as biodiesel blends based on Soybean, Sunflower and rapeseed. This paper examines also the degradation of several biofuels in comparison with fossil fuels (Diesel and gasoline) with different storage conditions over 9 Weeks period. The Results indicated that: High temperature combined with the lighting strongly enhances the degradation phenomenon. The acid value of biodiesel (HM) is rapidly increasing at a rate of 0.91 mg KOH/g /Week. The pH of diesel has experienced a strong decrease of 66%. In comparison with Diesel, Diesel degrades strongly and rapidly from a biodiesel in terms of Acid Value, pH and Density.

Technological advances and the pandemic have caused an explosion in demand for remote services. In critical processes such as banking, insurance and notary public, the service to be provided remotely has to be provided as quickly and safely as the service provided in presence. In such sensitive processes, the identity card authenticity detection must be done accurately and securely. One of the techniques used in accuracy detection is the use of mobile devices that support contactless chip technology. However, the number of mobile devices using this method is limited today. This situation hinders the effective and widespread use of remotely provided services and resources. Therefore, a different solution method was needed that would be an alternative to contactless chip technology, remove the obstacles to widespread use and reduce incidents such as counterfeiting. In this study, it was investigated whether the hologram, which is one of the security elements in the identity, can be used in determining the accuracy of Turkey's digital identity cards. For this purpose, a special function and program has been developed on the MATLAB application by using 2-D neighborhood methods to detect the crescent on the hologram. 227 digital ID cards were first evaluated on a mobile device over certain threshold values such as color level and similarity ratio. Then, each card used in the test was examined one by one with the naked eye. Approximately 99.56% similar results were obtained between the test findings made over the application and the findings obtained after the controls made with the naked eye. It has been concluded that the secure hologram image, one of the security elements on the digital ID card with this high success rate, can be used as computer aided in remote services. With this solution method, it has contributed to overcome an important obstacle in front of services that are thought to be provided remotely in many fields such as banks, notaries and education.
