Most of vehicle have the similar structures and designs. It is extremely complicated and difficult to identify and classify vehicle brands based on their structure and shape. As we requirea quick and reliable response, so vehicle logos are an alternative method of determining the type of a vehicle. In this paper, we propose a method for vehicle logo recognition based on feature selection method in a hybrid way. Vehicle logo images are first characterized by histograms of oriented gradient descriptors and the final features vector are then applied feature selection method to reduce the irrelevant information. Moreover, we release a new benchmark dataset for vehicle logo recognition and retrieval task namely, VLR-40. The experimental results are evaluated on this database which show the efficiency of the proposed approach.

A NEW MULTI CRITERIA DECISION MAKING METHOD : APPROACH OF LOGARITHMIC CONCEPT...ijaia
The primary aim of the study is to introduce APLOCO method which is developed for the solution of multicriteria
decision making problems both theoretically and practically. In this context, application subject of
APLACO constitutes evaluation of investment potential of different cities in metropolitan status in Turkey.
The secondary purpose of the study is to identify the independent variables affecting the factories in the
operating phase and to estimate the effect levels of independent variables on the dependent variable in the
organized industrial zones (OIZs), whose mission is to reduce regional development disparities and to
mobilize local production dynamics. For this purpose, the effect levels of independent variables on dependent variables have been determined using the multilayer perceptron (MLP) method, which has a wide use in artificial neural networks (ANNs). The effect levels derived from MLP have been then used as
the weight levels of the decision criteria in APLOCO. The independent variables included in MLP are also
used as the decision criteria in APLOCO. According to the results obtained from APLOCO, Istanbul city is
the best alternative in term of the investment potential and other alternatives are Manisa, Denizli, Izmir, Kocaeli, Bursa, Ankara, Adana, and Antalya, respectively. Although APLOCO is used to solve the ranking problem in order to show application process in the paper, it can be employed easily in the solution of classification and selection problems. On the other hand, the
study also shows a rare example of the nested usage of APLOCO which is one of the methods of operation
research as well as MLP used in determination of weights.

A NEW MULTI CRITERIA DECISION MAKING METHOD : APPROACH OF LOGARITHMIC CONCEPT...ijaia
The primary aim of the study is to introduce APLOCO method which is developed for the solution of multicriteria
decision making problems both theoretically and practically. In this context, application subject of
APLACO constitutes evaluation of investment potential of different cities in metropolitan status in Turkey.
The secondary purpose of the study is to identify the independent variables affecting the factories in the
operating phase and to estimate the effect levels of independent variables on the dependent variable in the
organized industrial zones (OIZs), whose mission is to reduce regional development disparities and to
mobilize local production dynamics. For this purpose, the effect levels of independent variables on dependent variables have been determined using the multilayer perceptron (MLP) method, which has a wide use in artificial neural networks (ANNs). The effect levels derived from MLP have been then used as
the weight levels of the decision criteria in APLOCO. The independent variables included in MLP are also
used as the decision criteria in APLOCO. According to the results obtained from APLOCO, Istanbul city is
the best alternative in term of the investment potential and other alternatives are Manisa, Denizli, Izmir, Kocaeli, Bursa, Ankara, Adana, and Antalya, respectively. Although APLOCO is used to solve the ranking problem in order to show application process in the paper, it can be employed easily in the solution of classification and selection problems. On the other hand, the
study also shows a rare example of the nested usage of APLOCO which is one of the methods of operation
research as well as MLP used in determination of weights.

The Impact of Digital Media on the Decentralization of Power and the Erosion ...ijtsrd
The impact of digital media on the distribution of power and the weakening of traditional gatekeepers has gained considerable attention in recent years. The adoption of digital technologies and the internet has resulted in declining influence and power for traditional gatekeepers such as publishing houses and news organizations. Simultaneously, digital media has facilitated the emergence of new voices and players in the media industry. Digital medias impact on power decentralization and gatekeeper erosion is visible in several ways. One significant aspect is the democratization of information, which enables anyone with an internet connection to publish and share content globally, leading to citizen journalism and bypassing traditional gatekeepers. Another aspect is the disruption of conventional media industry business models, as traditional organizations struggle to adjust to the decrease in advertising revenue and the rise of digital platforms. Alternative business models, such as subscription models and crowdfunding, have become more prevalent, leading to the emergence of new players. Overall, the impact of digital media on the distribution of power and the weakening of traditional gatekeepers has brought about significant changes in the media landscape and the way information is shared. Further research is required to fully comprehend the implications of these changes and their impact on society.

The Role of Mentoring and Its Influence on the Effectiveness of the Teaching ...ijtsrd
This paper reports on a study which was conducted to investigate the role of mentoring and its influence on the effectiveness of the teaching of Physics in secondary schools in the South West Region of Cameroon. The study adopted the convergent parallel mixed methods design, focusing on respondents in secondary schools in the South West Region of Cameroon. Both quantitative and qualitative data were collected, analysed separately, and the results were compared to see if the findings confirm or disconfirm each other. The quantitative analysis found that majority of the respondents 72 of Physics teachers affirmed that they had more experienced colleagues as mentors to help build their confidence, improve their teaching, and help them improve their effectiveness and efficiency in guiding learners’ achievements. Only 28 of the respondents disagreed with these statements. With majority respondents 72 agreeing with the statements, it implies that in most secondary schools, experienced Physics teachers act as mentors to build teachers’ confidence in teaching and improving students’ learning. The interview qualitative data analysis summarized how secondary school Principals use meetings with mentors and mentees to promote mentorship in the school milieu. This has helped strengthen teachers’ classroom practices in secondary schools in the South West Region of Cameroon. With the results confirming each other, the study recommends that mentoring should focus on helping teachers employ social interactions and instructional practices feedback and clarity in teaching that have direct measurable impact on students’ learning achievements.

This study primarily focuses on the design of a high side buck converter using an Arduino microcontroller. The converter is specifically intended for use in DC DC applications, particularly in standalone solar PV systems where the PV output voltage exceeds the load or battery voltage. To evaluate the performance of the converter, simulation experiments are conducted using Proteus Software. These simulations provide insights into the input and output voltages, currents, powers, and efficiency under different state of charge SoC conditions of a 12V,70Ah rechargeable lead acid battery. Additionally, the hardware design of the converter is implemented, and practical data is collected through operation, monitoring, and recording. By comparing the simulation results with the practical results, the efficiency and performance of the designed converter are assessed. The findings indicate that while the buck converter is suitable for practical use in standalone PV systems, its efficiency is compromised due to a lower output current.

Sustainable Energy by Paul A. Adekunte | Matthew N. O. Sadiku | Janet O. Sadikuijtsrd
Energy becomes sustainable if it meets the needs of the present without compromising the ability of future generations to meet their own needs. Some of the definitions of sustainable energy include the considerations of environmental aspects such as greenhouse gas emissions, social, and economic aspects such as energy poverty. Generally far more sustainable than fossil fuel are renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy sources. Worthy of note is that some renewable energy projects, like the clearing of forests to produce biofuels, can cause severe environmental damage. The sustainability of nuclear power which is a low carbon source is highly debated because of concerns about radioactive waste, nuclear proliferation, and accidents. The switching from coal to natural gas has environmental benefits, including a lower climate impact, but could lead to delay in switching to more sustainable options. “Carbon capture and storage” can be built into power plants to remove the carbon dioxide CO2 emissions, but this technology is expensive and has rarely been implemented. Leading non renewable energy sources around the world is fossil fuels, coal, petroleum, and natural gas. Nuclear energy is usually considered another non renewable energy source, although nuclear energy itself is a renewable energy source, but the material used in nuclear power plants is not. The paper addresses the issue of sustainable energy, its attendant benefits to the future generation, and humanity in general. Paul A. Adekunte | Matthew N. O. Sadiku | Janet O.

Concepts for Sudan Survey Act Implementations Executive Regulations and Stand...ijtsrd
This paper aims to outline the executive regulations, survey standards, and specifications required for the implementation of the Sudan Survey Act, and for regulating and organizing all surveying work activities in Sudan. The act has been discussed for more than 5 years. The Land Survey Act was initiated by the Sudan Survey Authority and all official legislations were headed by the Sudan Ministry of Justice till it was issued in 2022. The paper presents conceptual guidelines to be used for the Survey Act implementation and to regulate the survey work practice, standardizing the field surveys, processing, quality control, procedures, and the processes related to survey work carried out by the stakeholders and relevant authorities in Sudan. The conceptual guidelines are meant to improve the quality and harmonization of geospatial data and to aid decision making processes as well as geospatial information systems. The established comprehensive executive regulations will govern and regulate the implementation of the Sudan Survey Geomatics Act in all surveying and mapping practices undertaken by the Sudan Survey Authority SSA and state local survey departments for public or private sector organizations. The targeted standards and specifications include the reference frame, projection, coordinate systems, and the guidelines and specifications that must be followed in the field of survey work, processes, and mapping products. In the last few decades, there has been a growing awareness of the importance of geomatics activities and measurements on the Earths surface in space and time, together with observing and mapping the changes. In such cases, data must be captured promptly, standardized, and obtained with more accuracy and specified in much detail. The paper will also highlight the current situation in Sudan, the degree to which survey standards are used, the problems encountered, and the errors that arise from not using the standards and survey specifications.

Towards the Implementation of the Sudan Interpolated Geoid Model Khartoum Sta...ijtsrd
The discussions between ellipsoid and geoid have invoked many researchers during the recent decades, especially during the GNSS technology era, which had witnessed a great deal of development but still geoid undulation requires more investigations. To figure out a solution for Sudans local geoid, this research has tried to intake the possibility of determining the geoid model by following two approaches, gravimetric and geometrical geoid model determination, by making use of GNSS leveling benchmarks at Khartoum state. The Benchmarks are well distributed in the study area, in which, the horizontal coordinates and the height above the ellipsoid have been observed by GNSS while orthometric heights were carried out using precise leveling. The Global Geopotential Model GGM represented in EGM2008 has been exploited to figure out the geoid undulation at the benchmarks in the study area. This is followed by a fitting process, that has been done to suit the geoid undulation data which has been computed using GNSS leveling data and geoid undulation inspired by the EGM2008. Two geoid surfaces were created after the fitting process to ensure that they are identical and both of them could be counted for getting the same geoid undulation with an acceptable accuracy. In this respect, statistical operation played an important role in ensuring the consistency and integrity of the model by applying cross validation techniques splitting the data into training and testing datasets for building the geoid model and testing its eligibility. The geometrical solution for geoid undulation computation has been utilized by applying straightforward equations that facilitate the calculation of the geoid undulation directly through applying statistical techniques for the GNSS leveling data of the study area to get the common equation parameters values that could be utilized to calculate geoid undulation of any position in the study area within the claimed accuracy. Both systems were checked and proved eligible to be used within the study area with acceptable accuracy which may contribute to solving the geoid undulation problem in the Khartoum area, and be further generalized to determine the geoid model over the entire country, and this could be considered in the future, for regional and continental geoid model.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

on Markov Chain to forecast the energy demand in
Iran until 2020. GM (1,1) was applied in a study of
Chang and Kung [9] to improve investment
performance. Based on GM (1, 1), Li [10] gave an
improved GM to predict revenues of Jingdezhen’s
tourism from 2003-2010. He concluded that the much
better predictive result can be obtained by the
improved GM. In a study by Feng and Huang [11],
GM (1, 1) was applied to forecast the waste
production of Shanghai city.
Data Envelopment Analysis (DEA) is a related new
“data-oriented” approach to evaluate the performance
of a group of entities called Decision Making Units
(DMUs). DEA converts multi-inputs into multi-
outputs. The DEA model was quickly recognized as
an excellent and easily used methodology for
performance evaluations. In the original study of
Charnes et al., Data Envelopment Analysis was
described as a mathematical programming model that
is applied to observational data. It provides a new
way of obtaining empirical estimates of relations
including the production functions and efficient
production possibility surfaces. These are
cornerstones of modern economics. DEA has a
variety models; however, the super-SBM model can
deal with multiple inputs and outputs in order to
conduct a separate score and position. For instance,
Wang et al., used the super-SBM model for
calculating the efficiency of Vietnamese port logistics
companies. Zhao et al., measured the efficiency of the
green economy via the super-SBM model. Huang et
al., evaluated the efficiency of a sustainable hydrogen
production scheme. Continuing the previous
researches, we also use the super-SBM model to
measure the efficiency of automotive companies over
the world.
2. METHODOLOGY
2.1. Data Collection
In this research, a survey of the thirteen largest
automotive companies around the world is conducted.
The list of largest automotive companies gathered
from [2] as shown in Table 1. These companies are
the largest automobile companies that can represent
the entire automotive industry in the global market.
The Automotive segment activities include
development, design, manufacture, assembly, and
sale of vehicles (vehicle financing, sale of related
parts, and accessories). The Other Operations
segments of the automotive company are activities
related to information technology services, machine
tools, and automation plant solutions.

2.2. Establishing Input / Output Variables
Based on the knowledge of DEA and the operation process of an automobile company, the researcher decided to
select four inputs factors including total assets (Tal.as), total equity (Tal.eq) and operating expenses (O.exp); and
two output factors including revenues (Rev) and net incomes (Net.in). These data were collected from the
International Accounting Standards (IASs) [12].
2.3. Grey forecasting model
The research [6] was introduced the grey theory that can deal with the poor and shortage of data. The GM(1,1)
model in the grey theory system is a forecasting tool that predicts the future value based on the minimum
historical time series as four consecutive points at an equal interval. Based on two basic operations that include
Accumulated Generation Operations (AGO) and Inverse Accumulated Generation Operations (IAGO), the
process of establishment of the GM (1, 1) model is presented as follows:

3.2. Forecasting Accuracy
Forecasting plays an important and necessary role in modern management in planning for effective operations. It
is indisputable that forecasting always remains some errors, thus, all estimated values must check the accuracy
level by the Mean Absolute Percentage Error (MAPE) for each DMU over the primary period of 2016–2019 as
shown in Table 2.
TABLE 2 MAPE OFAUTOMOBILE COMPANIES
DMUs MAPE DMUs MAPE
DMU1 23.904 DMU8 11.123
DMU2 9.737 DMU9 11.766
DMU3 11.991 DMU10 25.612
DMU4 38.332 DMU11 24.111
DMU5 15.316 DMU12 18.805
DMU6 14.601 DMU13 12.359
DMU7 8.426
Table 2 indicates that all MAPEs are lower than 38.332 so that the MAPEs of all forecasting values are standard.
These predicted values over the period of 2020 – 2023 have high reliability that can use for computing
efficiency.

3.3. Pearson Correlation
According to the rule of DEA, all input and output variables must test the correlation coefficients to ensure
“isotonic” among two variables. The correlation coefficient is ranged from -1 to +1 and it has a perfect linear
program when this value is closer -1 and +1. In this study, the correlation coefficients are from 0.4638 to 1 so
that it has a good relationship. Therefore, all actual and forecasted input and output variables are proper for the
prerequisite of DEA model, they can apply to the super-SBM model for the next calculation.

DEA has many models such as EBM, SBM, and so on, but they cannot give separate efficiency, moreover, their
highest efficiency scores only reach to 1. In contrast, the super-SBM model can conduct separate value and
unlimited values in efficient cases. In this research, the effectiveness of the DMUs is calculated by the Super-
SBM model for actual and estimated data over the period of 2016–2023 as shown in Table 3.
Table 3 indicates the performance of all automotive companies from past to future time, most of them have a
fluctuation smoothly. There are three automotive companies including DMU1, DMU3, and DMU11 that reach to
the efficiency with an efficiency score above 1 in both previous time and future time. DMU2 holds high scores
in many terms, but its score was deducted sharply and did not attain the performance as 0.4032 in 2017. The
remaining terms in the previous time owned an efficiency score from 1.7312 to 1.7820. With the full effort, it is
expected that it will increase and reach a high score as 2.4112; 3.3913; 4.4379, and 4.4656, respectively from
2020 to 2023. DMU9 has a similar change as DMU2; however, future efficiency is from 1.1657 to 1.2668.
DMU7 and DMU12 have the same dramatic that reduced the score under 1 during the time period of 2017–2018,
and are expected to extend in the future time. The performance of DMU6 and DMU10 in whole term increases
and reduces consecutively, they attain the efficiency in three years from past to future time. DMU8 is a unique
automotive company which obtained a high score of 2.2354 in 2016, then, their scores are been down sharply
and do not get the efficiency in the remaining time. The remaining automotive companies including DMU4,
DMU5, and DMU13 are the worst companies that do not approach the performance in the whole term because
their scores are always lower than 1.
3.5. Ranking
Based on the efficiency score, the position of DMUs in every year is exhibited as seen in Table 4 particularly.

All DMUs have variation scores so that none of them
maintains the first position in the whole term. DMU2
holds the first rank from 2019 to 2013; it was in the
second, third, and ninth positions for the years 2018,
2016, and 2017, respectively. DMU11 reached to the
first rank in 2016 and 2018, remaining years are
second and third classification. DMU10 attained the
first rank in 2017, but other terms are the low position
from seventh to eleventh. DMU4 made a good effort
in operational progress in order to catch up on the
second position in 2017; however, it is been down to
the final rank in the remaining years. DMU5 ranked
ninth, eleventh, and seventh positions in 2016, 2017,
and 2018, respectively, and twelfth position in
remaining years.
The above analysis implies that DMU11 does not
have a highest efficiency score, it’s score is seen to be
stable and its position keeps first, second, and third
rank. DMU4 and DMU5 are the two worst
automotive companies that always have the low
efficiency scores and rank the bottom position.
Besides, the empirical result indicates that remaining
automotive companies do not come to the first rank;
they range from the second position to the final
position. Their positions in every year always change
consecutively.
4. CONCLUSION
Nowadays, the automobile industry is developing
sharply in many countries over the world because
economic development is the potential to make a
foundation for the growth of automobile companies.
In this study, we give a performance measurement of
thirteen automotive companies around the world from
past to future by using GM(1,1) model and super-
SBM model.
The standard accuracy estimated values are conducted
by GM(1,1) with the average MAPE of each
company under 38.332%. And then, all actual and
forecasted data are utilized to measure the
performance from past to future time. The final
analysis result found out four good automotive
companies including DMU1, DMU2, DMU3, and
DMU11 in which always reach the efficiency in the
whole time. In contrast, three automotive companies
including DMU4, DMU5, and DMU13 are
determined to be the worst companies that they do not
obtain the performance at any time.
The study conducts the performance and position of
each automotive company each year over the time
period of 2016–2023 but it still has some limitations.
Firstly, the amount of large automotive companies
does not gather fully because their financial
statements have not been published, further study
should found out more companies to have a full
observation. Secondly, the next study should present
more multiple inputs and outputs.
