Function Point Software Cost Estimates using Neuro-Fuzzy techniqueijceronline
Software estimation accuracy is among the greatest challenges for software developers. As Neurofuzzy based system is able to approximate the non-linear function with more precision so it is used as a soft computing approach to generate model by formulating the relationship based on its training. The approach presented in this paper is independent of the nature and type of estimation. In this paper, Function point is used as algorithmic model and an attempt is being made to validate the soundness of Neuro fuzzy technique using ISBSG and NASA project data.
HW/SW Partitioning Approach on Reconfigurable Multimedia System on ChipCSCJournals
Due to the complexity and the high performance requirement of multimedia applications, the design of embedded systems is the subject of different types of design constraints such as execution time, time to market, energy consumption, etc. Some approaches of joint software/hardware design (Co-design) were proposed in order to help the designer to seek an adequacy between applications and architecture that satisfies the different design constraints. This paper presents a new methodology for hardware/software partitioning on reconfigurable multimedia system on chip, based on dynamic and static steps. The first one uses the dynamic profiling and the second one uses the design trotter tools. The validation of our approach is made through 3D image synthesis.

Insights on Research Techniques towards Cost Estimation in Software Design IJECEIAES
Software cost estimation is of the most challenging task in project management in order to ensuring smoother development operation and target achievement. There has been evolution of various standards tools and techniques for cost estimation practiced in the industry at present times. However, it was never investigated about the overall picturization of effectiveness of such techniques till date. This paper initiates its contribution by presenting taxonomies of conventional cost-estimation techniques and then investigates the research trends towards frequently addressed problems in it. The paper also reviews the existing techniques in well-structured manner in order to highlight the problems addressed, techniques used, advantages associated and limitation explored from literatures. Finally, we also brief the explored open research issues as an added contribution to this manuscript.

Abstract The management of software cost, development effort and project planning are the key aspects of software development. Throughout the sixty-odd years of software development, the industry has gone at least four generations of programming languages and three major development paradigms. Still the total ability to move consistently from idea to product is yet to be achieved. In fact, recent studies document that the failure rate for software development has risen almost to 50 percent. There is no magic in managing software development successfully, but a number of issues related to software development make it unique. The basic problem of software development is risky. Some example of risk is error in estimation, schedule slips, project cancelled after numerous slips, high defect rate, system goes sour, business misunderstanding, false feature rich, staff turnover. XSoft Estimation addresses the risks by accurate measurement. A new methodology to estimate using software COSMIC-Full Function Point and named as EXtreme Software Estimation (XSoft Estimation). Based on the experience gained on the original XSoft project develpment, this paper describes what makes XSoft Estimation work from sizing to estimation. Keywords: -COSMIC function size unit, XSoft Estimation, XSoft Measurement, Cost Estimation.
APPLYING REQUIREMENT BASED COMPLEXITY FOR THE ESTIMATION OF SOFTWARE DEVELOPM...cscpconf
The need of computing the software complexity in requirement analysis phase of software
development life cycle (SDLC) would be an enormous benefit for estimating the required
development and testing effort for yet to be developed software. Also, a relationship between
source code and difficulty in developing a source code are also attempted in order to estimate the
complexity of the proposed software for cost estimation, man power build up, code and
developer’s evaluation. Therefore, this paper presents a systematic and an integrated approach
for the estimation of software development and testing effort on the basis of improved
requirement based complexity (IRBC) of the proposed software. The IRBC measure serves as the
basis for estimation of these software development activities to enable the developers and
practitioners to predict the critical information about the software development intricacies and
obtained from software requirement specification (SRS) of proposed software. Hence, this paper
presents an integrated approach, for the prediction of software development and testing effort
using IRBC. For validation purpose, the proposed measures are categorically compared with
various established and prevalent practices proposed in the past. Finally, the results obtained, validates the claim, for the approaches discussed in this paper, for estimation of software development and testing effort, in the early phases of SDLC appears to be robust, comprehensive, early alarming and compares well with other measures proposed in the past.
International Journal of Computational Engineering Research (IJCER) is dedicated to protecting personal information and will make every reasonable effort to handle collected information appropriately. All information collected, as well as related requests, will be handled as carefully and efficiently as possible in accordance with IJCER standards for integrity and objectivity.

Productivity Factors in Software Development for PC PlatformIJERA Editor
Identifying the most relevant factors influencing project performance is essential for implementing business strategies by selecting and adjusting proper improvement activities. The two major classification algorithms CRT and ANN that were recommended by the Auto Classifier tool in SPSS Modeler used for determining the most important variables (attributes) of software development in PC environment. While the accuracy of classification of productive versus non-productive cases are relatively close (72% vs 69%), their ranking of important variables are different. CRT ranks the Programming Language as the most important variable and Function Points as the least important. On the other hand, ANN ranks the Function Points as the most important followed by team size and Programming Language.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Abstract— With the development of software industry, software
estimation and measurement is catching much more concern. Scale
increasing in applications and a variety of programming languages
using at the same time, manual measurement based on the LOC
(Line of Code) cannot meet the estimating requirements. Security
is becoming more and more important in most of the software
construct. The emergence of Function Point resolves these difficult
issues. It is extensively used in production analysis and estimation.
FPA can also be used in the estimation of embedded and real-time
software. In recent years, Object Oriented (OO) technology has
emerged as a dominant practice in Software Engineering domain.
it is useful to match traditional Function Point (FP) measurement
to new OO approaches, including models based on Unified
Modeling Language. Web applications can be estimated by Web
objects. It is a quite different measure, since it starts from the most
classic functional size metric, Function Points, and extends it by
taking into account components that can be typically found in a
web system.
This paper gives about the overview of methods available in
function point analysis.
Index Terms— Software estimation, function point analysis,
web objects, fuzzy rules.
I. INTRODUCTION
Project progress, cost and quality are the three elements of
software projects. Size estimation is the key of software
engineering. The accurate estimation not only could promote
exploitation resources allocation, but also it deeply affects the
development of the software project. The software is invisible
and unmanageable, so the software size problem becomes
difficult. The facts show that estimating the software effort at
the early stages of the project will contribute to the management
arrangements for the project development plan, control the cost
and ensure the software quality at the same time. On the one
hand, software self could change according to function
requirements in the course of compilation. On the other hand,
the software size easily suffers many factors, such as person,
technology, and environment and exploiter strategy. Function
Point Analysis has been proposed in the late 70’ as an effective
means for measuring the size of software systems and
forecasting the development and maintenance effort ; its central
principle is the use of functional requirements as the main input
of size estimation, which overcomes the problems inherent to
the use of code-level, physical parameters for dimensioning the
software. It has steadily evolved into a functional size metric
consolidated in the Well-accepted Standardized International
Function Point User Group (IFPUG).
Section II says about the traditional function point analysis.

II. TRADITIONAL FUNCTION POINT ANALYSIS
A. Characteristics of function point
Function Point Analysis is a software estimation method that
oriented on function, which measures the size of system mainly
from its functionality and usability. In its view, system consists
of the following 5 characteristics:
EI (External Input): user input to the software which
provides application-oriented data.
EO (External Output): Report, screens, error messages
and so on.
EQ (External Query): a real-time response when users
enter an online input.
ILF (Internal Logical File): a logical main document,
such as a logical combination of data.
EIF (External Interface File): A machine-readable
interface, such as data files on the tapes or disks, which
can be used to transport information from one
System to the other.
Actually, function point is the sum of these weighted
characteristics.

B. Calculating function point
Determine the type of function point count. Function
point counts can be associated with either projects or
applications, which has three types: development
project, enhancement project and application.
Identify the counting scope and application boundary.
Count the data functions to determine their
contribution to the unadjusted function point count.

Count the transactional functions to determine their
contribution to the unadjusted function point count.
Determine the value adjustment Factor. The
value adjustment factor (VAF) is based on 14
general system characteristics (GSCs).
Then VAF (Value Adjustment Factor) is calculated
like this:
VAF = (TDI * 0.01) +0.65
Calculate the adjusted function point count
according to the formula below:
FP=VAF*UFP
In which UFP stands for Unadjusted Function Point.

III FULLFUNCTION POINTS
Full function points is a measure of the functional size of
the software, from a user perspective and not taking into
account the technical characteristics of the software. A new
measurement basis was introduced in FFP, together with
corresponding data and functional types closer to the control
data characteristics.
The two new Control data function types have a structure
similar to that of the IFPUG Data Function types:
Updated Control Group (UCG): It is a group of control
data updated by the application being measured. It is
identified from a functional perspective.
Read-Only Control Group (RCG): It is a group of
control data used, but not updated, by the application being
measured.
The four new Control transactional function types address
the sub process of real time software.
External Control Entry (ECE): It controls the data
coming from outside the application's boundary.
External Control Exit (ECX): It controls the data going
outside the application's boundary.
Internal Control Read (ICR): It reads the control
data. Internal Control Write (ICW): It writes control
data.
FFP is an extension of IFPUG measurement method; all
IFPUG rules can be included in an application of this new
Measurement technique. Unadjusted count of an application
using the FFP can be expressed as follows:
FFP=Management FP+Control FP
=(FPA-Control information)+Control
FP
IV IMPROVED FPA
An improved function point analysis (FPA) method was
proposed for analyzing the software size. The method
combined the advantage of the fuzzy rules and back
propagation (BP) network. Firstly, fuzzy inference system
based on the complexity weight matrix of function component
was established. Then the adjusted complexity weights were
used for modifying the software function point. The adjusted
data as samples were transferred to BP network. By the
advantage of BP network function approaching, the
relationship between software components and software size
was established. Finally, BP network was used for estimating
software size. The experiment results show that the method
could eliminate discontinuity among the different complexity
grades, and could make the best of history data, which
enhances the accuracy of function point estimation.
Fuzzy inference mainly uses fuzzy logistic method to
establish the mapping relationship between input space and
output space. It is suitable for describing uncertain
phenomena and natural for human understanding. Fuzzy
inference contains three main phases: fuzzification,
Fuzzy inference and defuzzification. Fuzzy variables are the
basis of fuzzy inference system. Combining the analysis
requirement of complexity weight, the DET and RET are the
input variable, while the complexity weight of ILF is the
output variable.

Fuzzy Rules of Complexity Analysis
We use a simple form of fuzzy rules and inference for better
human understanding. Each fuzzy rule is of the form “if A
then B”, where A and B are called an antecedent and a
consequent, respectively.
BP Neural Network Theory
The basic idea of BP network is as follows:
BP network is a sort of forward feedback network of owning
layer structure. It includes one input layer, one output layer
and a lot of connotative layer. It considers the error’s square
of neural network anticipant output value and the network
actual output value as the goal function of study (also called
the error function), according to the minimum rule to adjust
the network weight, finally the networks’ outputs match the
pre-specified targets and the goal function reaches the
minimum or permitted bound.
V EXTENDED FPA
Software houses are now to keen to provide secure
software as requested by customers' desire with respect to
security and quality of their products. Significantly security is
becoming more and more important in most of the software
construct. By engineering security, it will substantially raise
the software cost. Security adds a nominal 50 % to the
cost,10-90% on effort, and 5-43% on schedules. Therefore
estimation should be made earlier on the security costing to
overcome the financial shortage in the project management.
Selection of security standards
Software security characteristics formulation:
This formulation considered four common security
standards that are widely referred by local software
developers and developed over the past decade. It includes

VI COMPARISON WITH WEB OBJECTS
Web technologies, once exploited only for creating
hypermedia applications (static web sites), have known a
huge development, and now they are one of the cutting-edge
technologies for very different kinds of systems, from small
information centered applications to large enterprise-scale
commercial systems. The differences from traditional
software, in terms of technology, development model,
time-to-market needs, and volatility of requirements and so
on, pose serious challenges in adapting traditional size
metrics, like Function Points, to measure Web applications.
Web Objects [4] size measure can be considered as a
significant contribute to web-based applications measurement
field. It adds four new elements, related to web development,
to the five FP functions then, complexity weighting rules are
applied, and the sum of these weights becomes the functional
size of the web application. The new elements describe the
multimedia content of the pages (Multimedia files), the blocks
of different nature that compose the pages (Web Building
Blocks), as well as embedded Scripts and Links to external
applications and databases.
In practice, starting from the requirements of the ten examined
systems, we kept the original FP evaluation, and added to
it the specific evaluation of Web application characteristics,
according to Web Objects approach (Multimedia files, Web
Building Blocks, Embedded Scripts and Links to External
Applications and Databases). Clearly, the new estimate using
Web Objects is consistently higher than the original FP one,
because “points” were added, and never subtracted. To
correct for this systematic bias, we computed for each project
the percentage increase of Web Object estimate with respect
to FP and averaged the ten values. We got a 58% average
estimate increase, so we rescaled Web Object estimates,
dividing them by 1.58. We kept instead the original
productivity coefficient,
varying with the technology adopted in the project.
VII MODEL DRIVEN DEVELOPMENT
Specifically, an algorithm has been implemented for
performing the function point count of a software project
starting from its conceptual model. Differently from previous
approaches, the proposed technique works on the same
conceptual model that is used for producing the
implementation, eliminating any unnecessary ad-hoc
specification task. We evaluate the precision of the FP
computation algorithm on a set of real-world projects and
de-scribe its implementation within a commercial Model
Driven Development tool suite.
With the diffusion of the Unified Modeling Language and of
the Model-Driven Architecture, promoted by the Object
Management Group, the software developers’ community is
paying increasing attention to Model Driven Development
(MDD). These methods advocate a stronger automation of the
software life-cycle, based on the use of high-level conceptual
models of software solutions and on the iterative
transformation of high-level models into lower-level platform
specific models, until an executable representation of the
system is obtained. In the tool market, vendors are
Also committing to MDD by progressively incorporating
conceptual modeling and code generation capabilities in their
integrated development environments, further contributing to
the adoption of model-driven development.
The essential ingredient of the proposed approach is a formal
modeling notation suitable both for code generation and size
estimation. In this paper, we have adopted the Web Modeling
language, a UML profile for representing interactive systems,
especially suited for describing Web and Web Service
applications. WebML exploits general-purpose UML class
diagrams for representing the business objects underlying the
application, and a domain specific notation, called hypertext
diagrams, for expressing the structure of the application
front-end (be it a user interface or a Web Service interface).
WebML has enough expressive power to allow the
specification of multi-actor, distributed Web and Web service
applications and the complete generation of their code for
the JAVA2EE platform. A WebML conceptual model can
also be exploited as the input for the computation of the
application’s function points, according to the well-known
IFPUG counting rules.
I. CONCLUSION
The most effective way of evaluating the validity of a
size measure is to assess its performance in estimating
the development effort required by a software project.
This is
Why we chose to apply Function Points. WO estimates are
done web applications. The next step of the research will be
the development or the choice of a cost model more suited to
take as input a size expressed in Web Objects. In that way, we
will also be able to compare the obtained results with those of
the unique. The future work comprises the application of the
developed system to a large collection of projects developed
using WebML and Web Ratio, with a twofold purpose:
further evaluating and optimizing the precision of the
automatic counter, and evaluating the productivity of
model-driven development. The latter issue is very promising,
as no quantitative data are available on the true benefits of
MDD compared to traditional system development.

delivered per staff-months with the MDD approach could
foster the adoption of this promising methodology by
traditional developers.
An improved function point analysis method for software size
estimation is proposed. It mainly is applied to program early.
The method uses the fuzzy logical reference to modify the
function point. It could eliminate the uncontinuous of the
complexity weight. Modified function point as new samples
are transmitted to the input layer of BP network. According to
BP network, some similar software programs are estimated.
The results of research show that the improved method could
effectively deal with the flaw in the weight complexity
analysis. UML has been recognized as a powerful tool to
model the object-oriented software systems. Verification of
Function Point Analysis for object-oriented software
estimation is done through a case study of Web-based
Document Management System. The concept of variable
productivity and building a framework based on best unbiased
linear estimator. The equivalent weighted least mean square
problem is derived and solved it to arrive at an accurate
estimate of needed effort for future projects based on the
delivered function points. The individual function point
elements were not independent. Not all the function point
elements were related to effort, an effort prediction model
based on two function point elements (input function points
and output function points) was just as good as a effort
model based on total function points, an effort prediction
model based on the raw counts of the number of files and
number of outputs was only slightly worse than an effort
model based on total function points. It might be that this
dataset is atypical, for example, the results might be different
if the data were all from the same company. However, the
results indicate that in this case function points do not exhibit
the characteristics that would be expected of a valid size
metric (which requires the component elements to be
independent). In addition, the results suggest that simple
counts may be as effective as more complex size models as
effort predictors. This is particularly useful because the basic
counts are likely to be known reasonably accurately earlier in
the life cycle than the weighted counts (which rely on
knowing details such as the number of data items involved
and tiles accessed by each input). However, use of simple
counts does rely on the ability of individual organizations to
collect data and generate their own effort prediction models.
For example, in this dataset simple counts of number of inputs
and number of master files was a reasonable effort predictor
but in another dataset different counts might be better.
Another advantage of using raw counts might an
improvement in counting consistency as a result of simpler
counting rules. Kemerer investigated the consistency of
function point counts and found that the differences in
function point’s counts of the same system averaged 12.2%. It
is likely that simpler counts would reduce this counting error.
