A novel integrated approach for handling anomalies in RFID dataijujournal
Radio Frequency Identification (RFID) is a convenient technology employed in various applications. The
success of these RFID applications depends heavily on the quality of the data stream generated by RFID
readers. Due to various anomalies found predominantly in RFID data it limits the widespread adoption of
this technology. Our work is to eliminate the anomalies present in RFID data in an effective manner so that
it can be applied for high end applications. Our approach is a hybrid approach of middleware and
deferred because it is not always possible to remove all anomalies and redundancies in middleware. The
processing of other anomalies is deferred until the query time and cleaned by business rules. Experimental
results show that the proposed approach performs the cleaning in an effective manner compared to the
existing approaches.
UBIQUITOUS HEALTHCARE MONITORING SYSTEM USING INTEGRATED TRIAXIAL ACCELEROMET...ijujournal
Ubiquitous healthcare has become one of the prominent areas of research inorder to address the
challenges encountered in healthcare environment. In contribution to this area, this study developed a
system prototype that recommends diagonostic services based on physiological data collected in real time
from a distant patient. The prototype uses WBAN body sensors to be worn by the individual and an android
smart phone as a personal server. Physiological data is collected and uploaded to a Medical Health
Server (MHS) via GPRS/internet to be analysed. Our implemented prototype monitors the activity, location
and physiological data such as SpO2 and Heart Rate (HR) of the elderly and patients in rehabilitation. The
uploaded information can be accessed in real time by medical practitioners through a web application.
ENHANCING INDEPENDENT SENIOR LIVING THROUGH SMART HOME TECHNOLOGIESijujournal
The population of elderly folks is ballooning worldwide as people live longer. But getting older often
means declining health and trouble living solo. Smart home tech could keep an eye on old folks and get
help quickly when needed so they can stay independent. This paper looks at a system combining wireless
sensors, video watches, automation, resident monitoring, emergency detection, and remote access. Sensors
track health signs, activities, appliance use. Video analytics spot odd stuff like falls. Sensor fusion and
machine learning find normal patterns so wonks can see unhealthy changes and send alerts. Multi-channel
alerts reach caregivers and emergency folks. A LabVIEW can integrate devices and enables local and
remote oversight and can control and handle emergency responses. Benefits seem to be early illness clues,
quick help, less burden on caregivers, and optimized home settings. But will old folks use all this tech? Can
we prove it really helps folks live longer and better? More research on maximizing reliability and
evaluating real-world impacts is needed. But designed thoughtfully, smart homes could may profoundly
improve the aging experience.
HMR LOG ANALYZER: ANALYZE WEB APPLICATION LOGS OVER HADOOP MAPREDUCEijujournal
In today’s Internet world, log file analysis is becoming a necessary task for analyzing the customer’s
behavior in order to improve advertising and sales as well as for datasets like environment, medical,
banking system it is important to analyze the log data to get required knowledge from it. Web mining is the
process of discovering the knowledge from the web data. Log files are getting generated very fast at the
rate of 1-10 Mb/s per machine, a single data center can generate tens of terabytes of log data in a day.
These datasets are huge. In order to analyze such large datasets we need parallel processing system and
reliable data storage mechanism. Virtual database system is an effective solution for integrating the data
but it becomes inefficient for large datasets. The Hadoop framework provides reliable data storage by
Hadoop Distributed File System and MapReduce programming model which is a parallel processing
system for large datasets. Hadoop distributed file system breaks up input data and sends fractions of the
original data to several machines in hadoop cluster to hold blocks of data. This mechanism helps to
process log data in parallel using all the machines in the hadoop cluster and computes result efficiently.
The dominant approach provided by hadoop to “Store first query later”, loads the data to the Hadoop
Distributed File System and then executes queries written in Pig Latin. This approach reduces the response
time as well as the load on to the end system. This paper proposes a log analysis system using Hadoop
MapReduce which will provide accurate results in minimum response time.

SIX DEGREES OF SEPARATION TO IMPROVE ROUTING IN OPPORTUNISTIC NETWORKSijujournal
Opportunistic Networks are able to exploit social behavior to create connectivity opportunities. This
paradigm uses pair-wise contacts for routing messages between nodes. In this context we investigated if the
“six degrees of separation” conjecture of small-world networks can be used as a basis to route messages in
Opportunistic Networks. We propose a simple approach for routing that outperforms some popular
protocols in simulations that are carried out with real world traces using ONE simulator. We conclude that
static graph models are not suitable for underlay routing approaches in highly dynamic networks like
Opportunistic Networks without taking account of temporal factors such as time, duration and frequency of
previous encounters.

Networks (MANETS) to determine the best in different scenarios. We analyse these MANET routing
protocols by using NS-2 simulator. We specify how the Number of Nodes parameter influences their
performance. In this study, performance is calculated in terms of Packet Delivery Ratio, Average End to
End Delay, Normalised Routing Load and Average Throughput.

DETERMINING THE NETWORK THROUGHPUT AND FLOW RATE USING GSR AND AAL2Rijujournal
In multi-radio wireless mesh networks, one node is eligible to transmit packets over multiple channels to
different destination nodes simultaneously. This feature of multi-radio wireless mesh network makes high
throughput for the network and increase the chance for multi path routing. This is because the multiple
channel availability for transmission decreases the probability of the most elegant problem called as
interference problem which is either of interflow and intraflow type. For avoiding the problem like
interference and maintaining the constant network performance or increasing the performance the WMN
need to consider the packet aggregation and packet forwarding. Packet aggregation is process of collecting
several packets ready for transmission and sending them to the intended recipient through the channel,
while the packet forwarding holds the hop-by-hop routing. But choosing the correct path among different
available multiple paths is most the important factor in the both case for a routing algorithm. Hence the
most challenging factor is to determine a forwarding strategy which will provide the schedule for each
node for transmission within the channel. In this research work we have tried to implement two forwarding
strategies for the multi path multi radio WMN as the approximate solution for the above said problem. We
have implemented Global State Routing (GSR) which will consider the packet forwarding concept and
Aggregation Aware Layer 2 Routing (AAL2R) which considers the both concept i.e. both packet forwarding
and packet aggregation. After the successful implementation the network performance has been measured
by means of simulation study.

CHECKPOINTING WITH MINIMAL RECOVERY IN ADHOCNET BASED TMRijujournal
This paper describes two-fold approach towards utilizing Triple Modular Redundancy (TMR) in Wireless
Adhoc Network (AdocNet). A distributed checkpointing and recovery protocol is proposed. The protocol
eliminates useless checkpoints and helps in selecting only dependent processes in the concerned
checkpointing interval, to recover. A process starts recovery from its last checkpoint only if it finds that it is
dependent (directly or indirectly) on the faulty process. The recovery protocol also prevents the occurrence
of missing or orphan messages. In AdocNet, a set of three nodes (connected to each other) is considered to
form a TMR set, being designated as main, primary and secondary. A main node in one set may serve as
primary or secondary in another. Computation is not triplicated, but checkpoint by main is duplicated in its
primary so that primary can continue if main fails. Checkpoint by primary is then duplicated in secondary
if primary fails too.
Gateway Based Multi-Hop Distributed Energy Efficient Clustering Protocol for ...ijujournal
Wireless sensor network consists of application oriented and cheap micro-devices called sensors nodes
having potential of connecting the physical world with virtual world by their sensing abilities. These sensor
nodes are having restrained battery sources. Efficient energy management is current area of research in
wireless sensor networks. Here we advice one such energy aware multi-hop protocol (G-DEEC) for two
level heterogeneous networks. In G-DEEC, the Base Station is placed out of sensing area and rechargeable
gateway nodes are placed inside field with other randomly deployed sensor nodes. Simulation shows the
proposed protocol G-DEEC is better than single-hop DEEC in terms of number of half dead nodes, alive
nodes and dead nodes; thereby showing improvement in network lifetime and stability.
MODIFIED CCEF FOR ENERGY-EFFICIENCY AND EXTENDED NETWORK LIFETIME IN WSNSijujournal
The widespread application of wireless sensor networks (WNSs) is obstructed by the severely limited
energy constraints and security threat for sensor nodes. Since traditional routing and security schemes are
not suited for these networks, a large part of research focusses on energy efficient routing protocols while
extending the network lifetime. Uneven distribution of communication loads result in network partitioning.
Traditional novel en-route filtering approaches, notably commutative cipher based en-route filtering
(CCEF) saves energy by early filtering of false reports. However this approach main focus is security not
network lifetime is limited by fixed paths and underlying routing not suitable for WSNs. In order to cater
these problems we propose energy efficient routing and pre-deterministic key distribution with dynamic
path selection in CCEF. Modified CCEF (MCCEF) aims at saving energy and extending network lifetime
while maintaining filtering power as in CCEF. Experimental results demonstrate the validity of our
approach with an average of three times network lifetime extension, 5.022% energy savings, and similar
filtering power as the original scheme.
Human Mobility Patterns Modelling using CDRsijujournal
The research objectives are exploring characteristics of human mobility patterns, subsequently modelling
them mathematically depending on inter-event time ∆t and traveled distances ∆rparameters using CDRs
(Call Detailed Records). The observations are obtained from Armada festival in France. Understanding,
modelling and simulating human mobility among urban regions is excitement approach, due to
itsimportance in rescue situations for various events either indoor events like evacuation of buildings or
outdoor ones like public assemblies,community evacuation in casesemerged during emergency situations,
moreover serves urban planning and smart cities. The results of numerical simulation are consistent
withpreviousinvestigations findings in that real systems patterns are almost follow an exponential
distribution.Further experimentations could classify mobility patterns into major classes (work or off) days,
also radius of gyration could be considered as influential parameter in modelling human mobility,
additionally city rhythm could be extracted by modelling mobility speed of individuals.

PERFORMANCE COMPARISON OF ROUTING PROTOCOLS IN MOBILE AD HOC NETWORKSijujournal
Routing protocols have an important role in any Mobile Ad Hoc Network (MANET). Researchers have
elaborated several routing protocols that possess different performance levels. In this paper we give a
performance evaluation of AODV, DSR, DSDV, OLSR and DYMO routing protocols in Mobile Ad Hoc
Networks (MANETS) to determine the best in different scenarios. We analyse these MANET routing
protocols by using NS-2 simulator. We specify how the Number of Nodes parameter influences their
performance. In this study, performance is calculated in terms of Packet Delivery Ratio, Average End to

DETERMINING THE NETWORK THROUGHPUT AND FLOW RATE USING GSR AND AAL2Rijujournal
In multi-radio wireless mesh networks, one node is eligible to transmit packets over multiple channels to
different destination nodes simultaneously. This feature of multi-radio wireless mesh network makes high
throughput for the network and increase the chance for multi path routing. This is because the multiple
channel availability for transmission decreases the probability of the most elegant problem called as
interference problem which is either of interflow and intraflow type. For avoiding the problem like
interference and maintaining the constant network performance or increasing the performance the WMN
need to consider the packet aggregation and packet forwarding. Packet aggregation is process of collecting
several packets ready for transmission and sending them to the intended recipient through the channel,
while the packet forwarding holds the hop-by-hop routing. But choosing the correct path among different
available multiple paths is most the important factor in the both case for a routing algorithm. Hence the
most challenging factor is to determine a forwarding strategy which will provide the schedule for each
node for transmission within the channel. In this research work we have tried to implement two forwarding
strategies for the multi path multi radio WMN as the approximate solution for the above said problem. We
have implemented Global State Routing (GSR) which will consider the packet forwarding concept and
Aggregation Aware Layer 2 Routing (AAL2R) which considers the both concept i.e. both packet forwarding
and packet aggregation. After the successful implementation the network performance has been measured
by means of simulation study.

CHECKPOINTING WITH MINIMAL RECOVERY IN ADHOCNET BASED TMRijujournal
This paper describes two-fold approach towards utilizing Triple Modular Redundancy (TMR) in Wireless
Adhoc Network (AdocNet). A distributed checkpointing and recovery protocol is proposed. The protocol
eliminates useless checkpoints and helps in selecting only dependent processes in the concerned
checkpointing interval, to recover. A process starts recovery from its last checkpoint only if it finds that it is
dependent (directly or indirectly) on the faulty process. The recovery protocol also prevents the occurrence
of missing or orphan messages. In AdocNet, a set of three nodes (connected to each other) is considered to
form a TMR set, being designated as main, primary and secondary. A main node in one set may serve as
primary or secondary in another. Computation is not triplicated, but checkpoint by main is duplicated in its
primary so that primary can continue if main fails. Checkpoint by primary is then duplicated in secondary
if primary fails too.
Gateway Based Multi-Hop Distributed Energy Efficient Clustering Protocol for ...ijujournal
Wireless sensor network consists of application oriented and cheap micro-devices called sensors nodes
having potential of connecting the physical world with virtual world by their sensing abilities. These sensor
nodes are having restrained battery sources. Efficient energy management is current area of research in
wireless sensor networks. Here we advice one such energy aware multi-hop protocol (G-DEEC) for two
level heterogeneous networks. In G-DEEC, the Base Station is placed out of sensing area and rechargeable
gateway nodes are placed inside field with other randomly deployed sensor nodes. Simulation shows the
proposed protocol G-DEEC is better than single-hop DEEC in terms of number of half dead nodes, alive
nodes and dead nodes; thereby showing improvement in network lifetime and stability.
MODIFIED CCEF FOR ENERGY-EFFICIENCY AND EXTENDED NETWORK LIFETIME IN WSNSijujournal
The widespread application of wireless sensor networks (WNSs) is obstructed by the severely limited
energy constraints and security threat for sensor nodes. Since traditional routing and security schemes are
not suited for these networks, a large part of research focusses on energy efficient routing protocols while
extending the network lifetime. Uneven distribution of communication loads result in network partitioning.
Traditional novel en-route filtering approaches, notably commutative cipher based en-route filtering
(CCEF) saves energy by early filtering of false reports. However this approach main focus is security not
network lifetime is limited by fixed paths and underlying routing not suitable for WSNs. In order to cater
these problems we propose energy efficient routing and pre-deterministic key distribution with dynamic
path selection in CCEF. Modified CCEF (MCCEF) aims at saving energy and extending network lifetime
while maintaining filtering power as in CCEF. Experimental results demonstrate the validity of our
approach with an average of three times network lifetime extension, 5.022% energy savings, and similar
filtering power as the original scheme.
Human Mobility Patterns Modelling using CDRsijujournal
The research objectives are exploring characteristics of human mobility patterns, subsequently modelling
them mathematically depending on inter-event time ∆t and traveled distances ∆rparameters using CDRs
(Call Detailed Records). The observations are obtained from Armada festival in France. Understanding,
modelling and simulating human mobility among urban regions is excitement approach, due to
itsimportance in rescue situations for various events either indoor events like evacuation of buildings or
outdoor ones like public assemblies,community evacuation in casesemerged during emergency situations,
moreover serves urban planning and smart cities. The results of numerical simulation are consistent
withpreviousinvestigations findings in that real systems patterns are almost follow an exponential
distribution.Further experimentations could classify mobility patterns into major classes (work or off) days,
also radius of gyration could be considered as influential parameter in modelling human mobility,
additionally city rhythm could be extracted by modelling mobility speed of individuals.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
