This document presents an analysis of bounds on the zeros of polynomials with complex coefficients. It begins by reviewing several existing theorems that establish bounds on the location of zeros under various constraints on the coefficients. The main results of the paper are Theorem 1 and its corollaries, which generalize previous theorems by relaxing some restrictions on the coefficients. Theorem 1 establishes bounds on the zeros when the real parts and imaginary parts of the coefficients satisfy certain inequalities involving parameters λ and σ. The corollaries specialize Theorem 1 to various cases and relate it back to previous results. In summary, the paper extends the understanding of bounds on polynomial zeros by presenting new theorems with less restrictive assumptions on the coefficient values.

Also, there are challenges in the tendering phase that affect viability of projects thus delaying implementation, construction phase is beset with over-runs and disputes and last but not the least; provider skills are weak all across the value chain. Given the critical role of Steel Sector in ensuring a sustained growth trajectory for India, it is imperative that we identify the core issues affecting completion of infrastructure projects in India and chalk out initiatives that need to be acted upon in short term as well as long term.
Report No. 6 of 2012-13 – Performance Audit of Ultra Mega Power Projects unde...Life of A Public Auditor
Energy is one of the most critical components of infrastructure that determines the economic development of a country. The growth rate of demand for power is generally higher than the GDP growth rate. The XI Five Year Plan emphasized the need for removing infrastructure bottlenecks for sustained growth and proposed an investment of around ' 21 lakh crore in infrastructure sectors. Considering the magnitude of expansion the power sector required, Government of India (GOI) decided (November 2005) to develop Ultra Mega Power Projects (UMPPs)1, each with a projected capacity of around 4000 MW and cost of ' 16,000-20,000 crore. Ministry of Power (MOP) designated (November 2005) Power Finance Corporation Limited (PFC) as the nodal agency for the purpose of development of UMPPs through Special Purpose Vehicles (SPVs).
Out of 16 UMPPs identified so far (March 2012), PFC floated 12 SPVs as its wholly owned subsidiaries for development of UMPPs. The main activities undertaken by the SPVs are appointment of consultants, preparation of bid documents, evaluation of bids and award of projects, acquisition of land, fuel tie-up and obtaining various statutory clearances.
SPVs invited bids for six UMPPs during March 2006 to March 2012 and awarded four UMPPs, viz. Sasan in Madhya Pradesh, Mundra in Gujarat, Krishnapatnam in Andhra Pradesh, and Tilaiya in Jharkhand to the identified Developers. The remaining eight UMPPs are yet to be awarded. One unit of 800 MW of the Mundra UMPP was commissioned in February 2012.

A Study on Translucent Concrete Product and Its Properties by Using Optical F...IJMER
- Translucent concrete is a concrete based material with light-transferring properties,
obtained due to embedded light optical elements like Optical fibers used in concrete. Light is conducted
through the concrete from one end to the other. This results into a certain light pattern on the other
surface, depending on the fiber structure. Optical fibers transmit light so effectively that there is
virtually no loss of light conducted through the fibers. This paper deals with the modeling of such
translucent or transparent concrete blocks and panel and their usage and also the advantages it brings
in the field. The main purpose is to use sunlight as a light source to reduce the power consumption of
illumination and to use the optical fiber to sense the stress of structures and also use this concrete as an
architectural purpose of the building

Geochemistry and Genesis of Kammatturu Iron Ores of Devagiri Formation, Sandu...IJMER
The Greenstone belts of Karnataka are enriched in BIFs in Dharwar craton, where Iron
formations are confined to the basin shelf, clearly separated from the deeper-water iron formation that
accumulated at the basin margin and flanking the marine basin. Geochemical data procured in terms of
major, trace and REE are plotted in various diagrams to interpret the genesis of BIFs. Al2O3, Fe2O3 (T),
TiO2, CaO, and SiO2 abundances and ratios show a wide variation. Ni, Co, Zr, Sc, V, Rb, Sr, U, Th,
ΣREE, La, Ce and Eu anomalies and their binary relationships indicate that wherever the terrigenous
component has increased, the concentration of elements of felsic such as Zr and Hf has gone up. Elevated
concentrations of Ni, Co and Sc are contributed by chlorite and other components characteristic of basic
volcanic debris. The data suggest that these formations were generated by chemical and clastic
sedimentary processes on a shallow shelf. During transgression, chemical precipitation took place at the
sediment-water interface, whereas at the time of regression. Iron ore formed with sedimentary structures
and textures in Kammatturu area, in a setting where the water column was oxygenated.

compared with the analysis outcome
Non linear analysis of Robot Gun Support Structure using Equivalent Dynamic A...IJMER
Robot guns are being increasingly employed in automotive manufacturing to replace
risky jobs and also to increase productivity. Using a single robot for a single operation proves to be
expensive. Hence for cost optimization, multiple guns are mounted on a single robot and multiple
operations are performed. Robot Gun structure is an efficient way in which multiple welds can be done
simultaneously. However mounting several weld guns on a single structure induces a variety of
dynamic loads, especially during movement of the robot arm as it maneuvers to reach the weld
locations. The primary idea employed in this paper, is to model those dynamic loads as equivalent G
force loads in FEA. This approach will be on the conservative side, and will be saving time and
subsequently cost efficient. The approach of the paper is towards creating a standard operating
procedure when it comes to analysis of such structures, with emphasis on deploying various technical
aspects of FEA such as Non Linear Geometry, Multipoint Constraint Contact Algorithm, Multizone
meshing .

system. Membership functions are generated for the probe attack. Based on these rules we have
created the fuzzy inference system that is used as an input to neuro-fuzzy system. Fuzzy inference
system is loaded to neuro-fuzzy toolbox as an input and the final ANFIS structure is generated for
outcome of neuro-fuzzy approach. The experiments and evaluations of the proposed method were
done with NSL-KDD intrusion detection dataset. As the experimental results, the proposed approach
based on the combination of, two techniques using decision tree and Association rule mining
efficiently detected probe attacks. Experimental results shows better results for detecting intrusions as

Material Parameter and Effect of Thermal Load on Functionally Graded CylindersIJMER
The present study investigates the creep in a thick-walled composite cylinders made
up of aluminum/aluminum alloy matrix and reinforced with silicon carbide particles. The distribution
of SiCp is assumed to be either uniform or decreasing linearly from the inner to the outer radius of
the cylinder. The creep behavior of the cylinder has been described by threshold stress based creep
law with a stress exponent of 5. The composite cylinders are subjected to internal pressure which is
applied gradually and steady state condition of stress is assumed. The creep parameters required to
be used in creep law, are extracted by conducting regression analysis on the available experimental
results. The mathematical models have been developed to describe steady state creep in the composite
cylinder by using von-Mises criterion. Regression analysis is used to obtain the creep parameters
required in the study. The basic equilibrium equation of the cylinder and other constitutive equations
have been solved to obtain creep stresses in the cylinder. The effect of varying particle size, particle
content and temperature on the stresses in the composite cylinder has been analyzed. The study
revealed that the stress distributions in the cylinder do not vary significantly for various combinations
of particle size, particle content and operating temperature except for slight variation observed for
varying particle content. Functionally Graded Materials (FGMs) emerged and led to the development
of superior heat resistant materials.

Abstract: Iranian electric power industry has adopted Build Operate Transfer (BOT) approach in a number of projects as
an alternative to utilize private sector investment. Therefore, some power plant projects have been successfully implemented
through BOT such as South Isfahan power plant as a first BOT power plant; in contrast, some of them have been failed in
the procurement process. Thus, there is a need for improving procurement approaches for future BOT projects. This study
identifies and analysis various success factors in BOT power plant projects in Iran. The research methodology that has been
utilized including literature review, and survey questionnaire have distributed to BOT experts. Hence, this research
establishes success factors for BOT power plant project in Iran comprise of 33 factors. All 33 success factors are considered
as important factors in BOT infrastructure projects; moreover, there is a good agreement in significance of success factors
between government organization, consultants, and concessionaires.
Keywords: Success Factors, Power Plant, BOT, Iran
I. INTRODUCTION
The desire to attain the sustainability, in terms of economic, social and environmental demands the innovative
project undertaking. The innovative approach involves private sector especially in funding the project. In 80th decade, many
Asian countries started privatization of infrastructure to improve public facilities and increase the life level [1], [2], [3], [4],
[5]. The attractiveness of Build Operate and Transfer (BOT) approach has increased in developing countries due to the
advantages offered by the approach. The main advantage is the chances of government to utilize private sector’s investment,
management, and technology. Previous studies have assessed the market potential for producing the power, absorbing
foreign and local investment engaged in BOT procurement.
On the other hand, some BOT infrastructure projects have been failed around the world. Therefore, government and
promoters should notice to the l success factors in these projects. There are some existing researches in CSFs of BOT
projects around the world such as [6], [7], [8]. These studies have been done in CSFs of BOT projects only in China while it
needs to identify CSFs in other countries that have utilized BOT approach in their infrastructure projects. Therefore, since
there is no study to date in CSFs in BOT power plant projects in Iran, the research in this area will help both government
organization and concessionaire. This paper identifies critical success factors (CSFs) in BOT power plant projects in Iran.
II. BOT POWER PLANT IN IRAN
After changing economic trends in Iran, and with particular attention to the utilization of non-government sector
resources, Iran’s Ministry of Energy started to attract local and foreign investment by BOT and BOO methods to implement
infrastructure projects in power industry. The first power plant project proposed for private sector investment in construction
of power plant was in Kerman province in 1995. However it was dropped after the withdrawal of investor. Then, in 1999,
Parehsar power plant project in Gilan province proposed as an international tender was selected to be an international
consortium; however, the project was stopped due to the structural problems in the implementation process. Since
cancellation of that project, many projects came into negotiation but none of them reached to the stage of implementation.
Thus, the authorities in charge of the Iranian power industry and MAPNA Company initiated to remove the existing
impediments in the way of the execution of such plans by creating a new project [9]. Until now, South Isfahan Power Plant
has been identified as a pioneer and first Iranian IPP project. Given the nature of the project, the direct-negotiation-procedure
was selected for the assignment of works. The South Isfahan BOT project was thus launched. This project is the first BOT
Power Plant project that has been put into operation in the Iranian power industry. In this regard, a pre-agreement was signed
between Iran Power Development Corporation (IPDC) and MAPNA International Company in 2002. The period of time
specified for construction period was 3 years, and 20 years for the commercial operation period following the Commercial
Operation Date (COD) of the power plant. Recently, the government has decided to transfer the majority of the power plant
to the private sector; therefore, the government encourages the private sector to utilize Build Own Operate (BOO) approach
in power plant project. BOO is similar to BOT but without transferring to government, commonly used in Australia at the
beginning [10]. Table I illustrates BOT and BOO power plant projects in Iran.

III. RESEARCH METHODOLOGY
3.1. The procedure
The quantitative research methodology was employed in this research. Therefore, the research methodology was
considered for this study in two stages:
The first stage was a widespread literature review and interview with BOT experts to identify the success factors in BOT
projects. The most significant reviewed pervious researches included [11], [6], [12], [13], [14], [7], [15], [16], [17], [8],
[18]. The CSFs related to BOT projects were identified and recognized success factors with the most agreement by these
researchers as a benchmark for further researches. Hence, 33 success factors were identified in BOT infrastructure
projects.
The second stage was a survey questionnaire to government organizations, consultants, and concessionaires conducted
to evaluate the criticality of the listed CSFs.
3.2. The survey sample
The questionnaire explored some barriers that BOT power plant project encounter them. Therefore, the
questionnaire was conducted with BOT participants involved in the Iranian electric power industry. For this purpose, the
questionnaire was distributed to government organization, consultants, and concessionaires. A total of 142 questionnaires
were distributed to BOT and BOO experts according to three above categories. They were dispersed only by the researcher,
person by person, in order to help them if it is necessary. Moreover, this method of questionnaire distribution makes direct
access to the respondents to ensure that the respondents realize the requirements of the questionnaire. The direct method is
significant in encouraging respondent to answer the detailed questionnaire. A total of 129 questionnaires were gathered.
From this number, 123 questionnaires were considered as valid questionnaires for analysis (Table II).

The questionnaire was written in English language, but it was translated to Persian language because the study area
was in Iran, and questionnaires were distributed among Iranian experts in BOT projects and also to facilitate easier reading
and compatibility of understanding. The Likert scale was selected to obtain weight of 33 success factors to BOT power plant
project in Iran. In this type of question, the respondents answer based on the amount of importance where 1 represented “not
important”, 2 “less important”, 3 “important”, and 4 “most important”.
3.3. Data Analysis
The respondents are grouped into their position in organization or company including Managing Director, Project
Manager, Technical Manager, Financial Manager, Planning Manager, and Junior Manager. These questionnaires’ results are
considered as reliable and valid, since the majority of the respondents were in positions of senior or middle manager. Table
III illustrates the position of respondents in their organization or company.

Consultants 3 15 6 ----- 6 3 33
Total 3 48 12 6 18 36 123
On the other hand, these questionnaires’ results are considered as reliable and valid in terms of their academic
qualification. It means that 49 percent (60 people) of respondents approximately possess the Bachelor Degree and 51 percent
(63 people) possess the Master Degree. Figure 1 shows number of respondents’ academic qualification in three categories.
Figure1. Academic qualification of respondents
In order to increase the reliability and validity of data collection, all respondents were selected through experts who
had experience in BOT infrastructure projects in Iran. In public organization, 15 respondents have 6-10 years experience in
BOT power plant projects and 9 respondents have less than 6 years experience in this field. It means that 78.5 percent of the
respondents have more than 6 years experience in BOT projects. Moreover, in concessioners, 33 respondents have 6-10
years experience in BOT power plant projects and 12 respondents have less than 6 years experience in this field. It clearly
seems that the majority of respondents (75%) have experience in BOT project more than 6 years. Finally, in consultants’
category, around half of the respondents (45.5%) have more than 6 years experience in BOT power plant projects in Iran.
Therefore, it corroborates to obtain high-quality data to ensure regarding the reliability and validity of data collection. Figure
2 illustrates the experience of respondents in BOT infrastructure projects.

one BOT power plant projects, 27 respondents in 2-5 projects, and 3 respondents in 6-10 projects. Therefore, this refers to
62.5 percent cooperation of the respondents in more than 2 BOT power plant projects. Furthermore, in consultants’ category,
21 respondents have worked in 2-5 BOT power plant projects, 3 respondents in 6-10 projects, and 3 respondents in more
than 11 projects. This implies to 82 percent collaboration of the respondents in more than 2 BOT power plant projects.
Finally, it is concluded that the majority of the respondents (75%) have totally been involved in more than 2 BOT power
plant projects. The respondents’ participation in BOT infrastructure projects in Iran is indicated in Figure 3.

The method utilized in this research was one-way ANOVA data analysis. This method is used where we have one
independent variable whit three or more levels (groups) and one dependent continuous variable. As mentioned earlier, there
are three categories of the respondents including government organization, concessionaires, and consultants. This method of
analysis is also utilized to show the differences or similarities of their comments.
IV. FINDING AND DISCUSSION
Thirty three success factors have been considered to recognize respondents’ ideas in these three classifications
including consultants (33 persons), the government organization (42 persons), and concessionaires (48 persons). The mean
scores of assigned by consultants to Appropriate project identification, Stable political situation, Favorable legislation
regulation, and Well-organized and committed public agency are greater than 3.50. This indicates that these three factors are

the most important factors in view of consultants (Table IV). On the other hand, the mean scores of twenty nine sub-factors
have been considered between 2.50 to 3.50. These sub-factors comprise of Favorable project management, Attractive
financial package, Reasonable risk allocation, Government support, Commitment and responsibility of public and private
sectors, Competitive and transparent procurement process, Experience with BOT project by public sector, Utilize local
company in project company, Technology transfer, and Concrete concession agreement, Select suitable consortium,
Overhauling guarantees, Sound environment impact, Training local staff, A multidisciplinary and multinational team, Short
concession period, Good relationship with government, Public safety, Social support, Profit sharing with government,
Special guarantees by the government, Select suitable subcontractor, Standardization of engineering contract, Multilateral
investment guarantees agency insurance, Technical solution advance, Quality control and supervision, Capability to lead
project by government, Operation in good condition, and Financial market availability. This refers to the significance of
these 29 success factors in view of consultants. Therefore, in their viewpoint, all thirty three success factors are regarded as
important or the most important factors because their mean scores are greater than 2.50.
Moreover, in government organization, the success factor of Attractive financial package has the highest
mean score (3.67) and is considered as the most important through all thirty three sub-factors. This is followed by Stable
political situation (score of 3.64), Favorable legislation regulation (score of 3.62), Reasonable risk allocation (score of 3.59),
and Favorable project management (score of 3.51) by considering of mean score more than 3.50. Furthermore, the mean
scores of twenty eight factors have been considered between 2.50 to 3.50. These factors comprise of Appropriate project
identification, Technical solution advance, Technology transfer, Utilize local company in project company, Reasonable risk
allocation, Commitment & responsibility of public & private sectors, Concrete concession agreement, Select suitable
consortium, Government support, Overhauling guarantees, Profit sharing with government, Good relationship with
government , Training local staff, Quality control and supervision, Sound environment impact, Select suitable subcontractor,
A multidisciplinary and multinational team, Standardization of engineering contract, Short concession period, Competitive
& transparent procurement process, Public safety, Experience with BOT project by public sector, Multilateral investment
guarantees agency insurance, Capability to lead project by government, Special guarantees by the government , Well-
organized & committed public agency, Operation in good condition, Social support, and Financial market availability. This
implies that these 28 aforementioned success factors are important in view of government organization. Therefore, in their
viewpoint, all thirty three critical success sub-factors are also regarded as important or the most important factors because of
their mean scores greater than 2.50.
Furthermore, in category of concessionaires, the success factors of Capability to lead project by government has the
highest mean score (3.63) and is considered the most important through of all thirty three sub-factors. The mean scores
assigned to Stable political situation, Favorable legislation regulation, and Appropriate project identification are greater than
3.50. In other words, this indicates the importance of these three factors through others in concessionaires’ viewpoint.
Moreover, the mean scores of twenty nine factors consist of Experience with BOT project by public sector, Competitive and
transparent procurement process, Special guarantees by the government, Commitment and responsibility of public and
private sectors, Social support, Utilize local company in project company, Government support, Concrete concession
agreement, Select suitable consortium, Technology transfer, Standardization of engineering contract, Good relationship with
government, Favorable project management , Profit sharing with government, Technical solution advance, Sound
environment impact, Quality control and supervision, Training local staff, A multidisciplinary and multinational team, Public
safety, Reasonable risk allocation, Select suitable subcontractor, Overhauling guarantees, Attractive financial package,
Multilateral investment guarantees agency insurance, Well-organized & committed public agency, Short concession period,
Operation in good condition, and Financial market availability have been considered between 2.50 to 3.50. This implies that
these 29 success factors are important in view of concessionaires. Therefore, because of the mean scores of all 33 success
factors greater than 2.50, they are concerned as important or the most important factors in view of the concessionaires.
In Table IV, from the analysis, it is concluded that the most important sub-factors (rank 1) in viewpoint of three
categories respondents are Appropriate project identification” for consultants, Attractive financial package for a government
organization, and Capability to lead the project by government for concessionaires. Appropriate project identification is the
most important success factors in project procurement system in consultants’ view because it needs to utilize especial experts
in BOT projects by the government. While, government organization respondents pointed to the attractive financial package
as the most significant factors in BOT projects because they have concentrated on the best financial proposal by
concessionaires to solve their limited budget. In contrast, concessionaires noticed to the government’s ability to lead projects
because it is more important to success the infrastructure projects in their viewpoint. The least important factor (rank 33)
belongs to Financial market availability for all three classifications of the respondents. In other words, all respondents
believe that financial market availability does not play significant role as the success factor in BOT infrastructure projects.
Eventually, although there are some differences in rank, the mean scores are very close and more than 2.50. Hence,
all 33 success factors are considered as important factors in BOT infrastructure projects. There is no important difference
between consultants, government organization, and concessionaires in respect of the success factors in BOT infrastructure
projects according to the statistical results (significance) because significant indexes are more than 0.05 [19].

V. CONCLUSION
BOT approach has a key role in rapid development of Iranian electric power industry to provide energy for massive
demand in economic growth. According to extensive literature review, this research establishes success factors for BOT
power plant project in Iran comprise of 33 factors.
In This study, 123 valid questionnaires were received from the respondents including government organization,
consultants, and concessionaires. These questionnaires’ results are considered as reliable and valid since the majority of the
respondents were in positions of senior or middle manager. Moreover, majority of the respondents had BOT experience
more than 6 years in government organization and concessionaires.
From the analysis, the mean scores of assigned by consultants to Appropriate project identification, Stable political
situation, Favorable legislation regulation, and Well-organized & committed public agency are greater than 3.50. This
indicates that these three factors are the most important factors in view of the consultants. For government organization, the
success factor of Attractive financial package has the highest mean score (3.67) and is considered the most important
through all thirty three sub-factors. Capability to lead the project by government with highest mean scores (3.63) is
considered as the most important factors through all 33 success factors by concessionaires. The assigned mean scores to
Stable political situation, Favorable legislation regulation, and Appropriate project identification are greater than 3.50.
Despite the difference in ranking, the mean scores are very close and more than 2.50. Therefore, the respondents believe that
all thirty three success factors are important in BOT infrastructure projects. There are no significant differences between
consultants, government organization, and concessionaires in respect of the success factors in BOT power plant projects in
Iran.
