1) During a routine anatomy dissection, researchers observed an unusual branching pattern of the brachial artery in a male cadaver.
2) Specifically, they found that the ulnar artery originated from the lateral side of the brachial artery, rather than in the cubital fossa as is typical.
3) The variant ulnar artery descended on the lateral forearm and crossed to the medial side, following a superficial path along the arm.
Occipitalization of atlas vertebra- A Case reportiosrphr_editor
During routine activities in the department of Anatomy,GSVM, Medical College Kanpur(U.P), an atlanto-occipital fusion was observed in cadaveric skull. The skull used in our study had complete fusion of the atlas vertebra with occipital bone along with ossification of atlanto-occipital membranes. The knowledge of such a fusion may be of importance for radiologists, anaesthetist, orthopedic and neurosurgeons because skeletal abnormalities at the craniocervical junction may result in sudden unexpected death. It can result in dysphagia, dysarthria or torticollis because of compression of cranial nerves. Neurosurgeons should be aware that such an anomaly may exist without any typical symptomatic presentation, and thus serious consequences of upper cervical spinal manipulative therapy may arise when a complete and adequate clinical assessment is missed.

Optimization of Bolted Joints for Aircraft Engine Using Genetic AlgorithmsIJMER
Genetic Algorithms mimic the evolving technique of nature to better fit populations to a certain environment. Despite this technique has proved its adequacy in several fields, its application in Aerospace is still limited, mostly because of the high quantity of acceptability criteria that the design
must pass and the amount of design parameters. The presented paper explores required GA architecture’s adaptations to be applied in highly restricted systems such as those commonly found in Aerospace applications. The proposed GA was applied to the design of an Aircraft Engine’s Axial Casing bolted joint following static strength restrictions as per FAR 33 regulations. The set of Elitism,
interdependent geometric restrictions, Crossing, and Reproduction modules proved the applicability of
the presented multi-objective GA architecture under 14 restrictions for normal, limit and ultimate loads.
As it is described, the conversion is quickly achieved due to the shortage of the search space; therefore a
modified Variable Crossing per Scheme is proposed to expand the diversity of the genome to compensate
the relatively low impact of the Mutation module. Finally, the process and solutions found were compared against the traditional design process, showing the feasibility of this technique in complex applications in terms of quality of the solution and developing time.

A Review of FDM Based Parts to Act as Rapid ToolingIJMER
Abstract: Fused Deposition Modeling (FDM) is one from basic Rapid Prototyping (RP) technologies
used in technical practice. In this contribution are presented basic information about parameters such
as layer thickness, part build orientation, raster angle, raster width and air gap. This study provides
insight into complex dependency of strength on process parameters. In this paper microphotographs
are used to show the mechanism of failure. The major reason for weak strength is attributed to
distortion within or between the layers.Developing a curved layer deposition methodology can
improve part quality by reduced lamination, reduction in the staircase effect which leads to improved
dimensional accuracy of the part. Less effort has been made to increase the range of FDM materials
to include metals or metal based composites with the help of metal based composite direct rapid
tooling will allow fabrication of injection moulding dies and inserts with desired thermal and
mechanical properties suitable for using directly in injection moulding machines for short term or
long term production runs.

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

Study & Testing Of Bio-Composite Material Based On Munja FibreIJMER
The incorporation of natural fibres such as munja fiber composites has gained
increasing applications both in many areas of Engineering and Technology. The aim of this study is to
evaluate mechanical properties such as flexural and tensile properties of reinforced epoxy composites.
This is mainly due to their applicable benefits as they are light weight and offer low cost compared to
synthetic fibre composites. Munja fibres recently have been a substitute material in many weight-critical
applications in areas such as aerospace, automotive and other high demanding industrial sectors. In
this study, natural munja fibre composites and munja/fibreglass hybrid composites were fabricated by a
combination of hand lay-up and cold-press methods. A new variety in munja fibre is the present work
the main aim of the work is to extract the neat fibre and is characterized for its flexural characteristics.
The composites are fabricated by reinforcing untreated and treated fibre and are tested for their
mechanical, properties strictly as per ASTM procedures.

Fabrication & Characterization of Bio Composite Materials Based On Sunnhemp F...IJMER
The present day technology demands eco-friendly developments. In this era the
composite material are playing a vital roal in different field of Engineering .The composite materials
are using as a principle materials. Nowaday the composite materials are utilizing as a important
component of engineering field .Where as the importance of the applications of composites is well
known, but thrust on the use of natural fibres in it for reinforcement has been given priority for some
times. But changing from synthetic fibres to natural fibres provides only half green-composites. A
partial green composite will be achieved if the matrix component is also eco-friendly. Keeping this in
view, a detailed literature surveyed has been carried out through various issues of the Journals
related to this field. The material systems used are sunnhemp fibres. Some epoxy and hardener has
been also added for stability and drying of the bio-composites. Various graphs and bar-charts are

likely to get applications in fall ceilings, partitions, bio-degradable packagings, automotive interiors,
sports things (e.g. rackets, nets, etc.), toys etc.
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.

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 .

Intrusion Detection and Forensics based on decision tree and Association rule...IJMER
This paper present an approach based on the combination of, two techniques using
decision tree and Association rule mining for Probe attack detection. This approach proves to be
better than the traditional approach of generating rules for fuzzy expert system by clustering methods.
Association rule mining for selecting the best attributes together and decision tree for identifying the
best parameters together to create the rules for fuzzy expert system. After that rules for fuzzy expert
system are generated using association rule mining and decision trees. Decision trees is generated for
dataset and to find the basic parameters for creating the membership functions of fuzzy inference
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
compared to others existing methods
Natural Language Ambiguity and its Effect on Machine LearningIJMER
"Natural language processing" here refers to the use and ability of systems to process
sentences in a natural language such as English, rather than in a specialized artificial computer
language such as C++. The systems of real interest here are digital computers of the type we think of as
personal computers and mainframes. Of course humans can process natural languages, but for us the
question is whether digital computers can or ever will process natural languages. We have tried to
explore in depth and break down the types of ambiguities persistent throughout the natural languages
and provide an answer to the question “How it affects the machine translation process and thereby
machine learning as whole?” .
Today in era of software industry there is no perfect software framework available for
analysis and software development. Currently there are enormous number of software development
process exists which can be implemented to stabilize the process of developing a software system. But no
perfect system is recognized till yet which can help software developers for opting of best software
development process. This paper present the framework of skillful system combined with Likert scale. With
the help of Likert scale we define a rule based model and delegate some mass score to every process and
develop one tool name as MuxSet which will help the software developers to select an appropriate
development process that may enhance the probability of system success.
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: During routine dissection for Ist MBBS students on 65 year old donated embalmed male cadaver in the
Department of Anatomy, K.J.Somaiya Medical College, Sion, Mumbai, India, we observed an unusual branch of the brachial
artery. The brachial artery terminated in the cubital fossa into radial and common interosseous arteries. The radial artery
had normal course and branches. The common interosseous artery was deeper and gave anterior and posterior ulnar
recurrent arteries, and terminated into anterior and posterior interosseous arteries. The unusual large branch from the
brachial artery was a variant of ulnar artery, arose from the lateral side of the brachial artery, descended on the lateral side
upto the cubital fossa and crossed the fossa from lateral to medial, superficial to median nerve. It then descended superficial
to the muscles arising from medial epicondyle of the humerus and was covered by the deep fascia of the forearm, pierced the
deep fascia proximal to the wrist, crossed the flexor retinaculum, and formed the superficial palmar arch. Throughout its
course, this artery gave no branch. There were no associated altered anatomy of the nerves observed in the specimen. The
left upper limb of the same cadaver was normal. The photographs of the variations were taken for proper documentation and
for ready reference. The embryological basis of the variation is presented.
Key words: Brachial artery, superficial antebrachial artery, superficial brachial artery, superficial ulnar artery, ulnar
artery.
I. Introduction:
The brachial artery ends in the cubital fossa by dividing into radial and ulnar arteries. At the elbow, the ulnar artery
sinks deeply into the cubital fossa and reaches the medial side of the forearm midway between elbow and wrist. The
common interosseous artery is a short branch of the ulnar, passes back to the proximal border of the interosseous membrane
and divides into anterior and posterior interosseous arteries. Anterior interosseous artery descends on the anterior aspect of
the interosseous membrane with the median nerve's anterior interosseous branch. Median artery, a slender branch from
anterior interosseous artery, accompanies and supplies the median nerve. (Williams et al, 1995)
II. Case Report:
During routine dissection for Ist MBBS students on 65 year old donated embalmed male cadaver in the Department
of Anatomy, K.J.Somaiya Medical College, Sion, Mumbai, India, we observed an unusual branch of the right brachial artery.
The brachial artery terminated in the cubital fossa into radial and common interosseous arteries. The radial artery had normal
course and branches. The common interosseous artery was deeper and gave anterior and posterior ulnar recurrent arteries,
and terminated into anterior and posterior interosseous arteries. The unusual large branch from the brachial artery was a
variant of ulnar artery, arose from the lateral side of the brachial artery, descended on the lateral side upto the cubital fossa
and crossed the fossa from lateral to medial, superficial to median nerve. It then descended superficial to the muscles arising

no branch. There were no associated altered anatomy of the nerves observed in the specimen. The left upper limb of the
same cadaver was normal. The photographs of the variations were taken for proper documentation and for ready reference.
The photographs were taken for proper documentation.
III. Observations:
The unusual large branch from the brachial artery was a variant of ulnar artery, arose from the lateral side of the
brachial artery in the axilla of right upper limb.

IV. Discussion:
The variations in branching pattern of axillary artery are a rule rather than exception (2, 3, 4, 5, 6, 7, 8, 9, 10, 11,
12, 13, 14, 15, 16). Variant branches may arise from the brachial artery (17). Ulnar artery was found to deviate from its usual
mode of origin in one in thirteen cases; frequently it sprang from the lower part of the brachial artery; the position of the
ulnar artery in the forearm was more frequently altered; in cases of high origin, it invariably descended over the muscles
arising from the medial epicondyle of the humerus and was covered by the deep fascia of the forearm (2). The present case
of ulnar artery is somewhat similar to the variations presented in Quain's Anatomy (2). If the brachial artery is taken to
terminate into radial and ulnar arteries, the embryological basis of the existing ulnar artery and the origin and course of the
unusual branch of the brachial artery, replacing the ulnar artery in the present case, is as follows. Primitive axis artery and
superficial brachial artery are implicated in the morphogenesis of the arteries of the upper limb (3, 18). The seventh cervical
intersegmental artery forms the axis artery of the upper limb and persists in the adult to form the axillary, brachial, and
interosseous arteries. Transiently, the median artery arises as a branch of the interosseous artery, begins to regress and
remains as a residual artery accompanying the median nerve (18). Radial and ulnar arteries are later additions to the axis
artery. An ulnar artery and a median artery are branches of the axis artery (8). A superficial brachial artery is a consistent
embryonic vessel, coexisting or not with the brachial artery (19). It has two terminal branches, a lateral that continues as a
part of the definitive radial artery (20) and a medial, superficial antebrachial artery, which divides into median and ulnar
artery branches, which are the trunks of origin of the median and ulnar arteries. These trunks of deep origin predominate and
the superficial arteries regress (8). In the present case, the axis artery had formed the interosseous artery and given the trunks
of the median and ulnar arteries. The ulnar branch of the superficial antebrachial artery persists independently, without its
usual anastomosis to the branch of the axis atery, as the large lateral branch of the brachial artery and the superficial ulnar
atery, which is found in the distal part of the forearm and joins the superficial palmar arch. If the brachial artery is taken to
terminate into radial and interosseous arteries, the simpler embryological basis of the interosseous artery and the origin and
course of the unusual branch of the brachial artery, replacing the ulnar artery, is the following. It appears probable that the
abnormal arrangement results from early obstruction of the ulnar artery below the origin of the interosseous, and the
development of a superficial vas aberrans, which replaces the portion of vessel below the obstrution and unites with the
brachial. The interosseous artery in such cases of abnormality thus comprises not only the interosseous artery but also the
portion of ulnar artery above the obstruction. and, in accordance with this view, the recurrent branches are derived from it
(2). The present anomaly is very rare and does not seem to have been reported. This case is of significance. Such an artery
may present a superficial pulse and a hazard to venipuncture (21) and lead to intra-arterial injections or ligature instead of the
vein in the cubital fossa (22, 23) Variation in the branching pattern of the brachial artery is of significance in cardiac
catheterization for angioplasty, pedicle flaps, arterial grafting or brachial pulse.
V. Conclusion:
The knowledge of presence of the unusual origin of the ulnar artery from the brachial artery in the axilla may be
clinically important for clinicians, surgeons, orthopaedicians and radiologists performing angiographic studies. Undoubtedly,
such variations are important for diagnostic evaluation and surgical management of vascular diseases and injuries. These
variations are compared with the earlier data & it is concluded that variations in branching pattern of axillary artery are a rule
rather than exception. Therefore both the normal and abnormal anatomy of the region should be well known for accurate
diagnostic interpretation and therapeutic intervention.
