Abstract This review article focuses on the various environment monitoring systems developed over the years. The development of any monitoring system is dependent on certain key factors namely cost of the system, energy efficiency of the system, signal to noise ratio, interference rejection during varying atmospheric conditions. The complexity of any system depends upon the number of nodes the system requires to monitor, the more the number of nodes the more complex structure becomes. If we use smart sensor network with each node independently functioning and transmitting data to one parent node that performs required processing the complexity decreases.

Design and Implementation of Portable Outdoor Air Quality Measurement System ...IJECEIAES
Recently, there is increasing public awareness of the real time air quality due to air pollution can cause severe effects to human health and environments. The Air Pollutant Index (API) in Malaysia is measured by Department of Environment (DOE) using stationary and expensive monitoring station called Continuous Air Quality Monitoring stations (CAQMs) that are only placed in areas that have high population densities and high industrial activities. Moreover, Malaysia did not include particulate matter with the size of less than 2.5µm (PM2.5) in the API measurement system. In this paper, we present a cost effective and portable air quality measurement system using Arduino Uno microcontroller and four low cost sensors. This device allows people to measure API in any place they want. It is capable to measure the concentration of carbon monoxide (CO), ground level ozone (O3) and particulate matters (PM10 & PM2.5) in the air and convert the readings to API value. This system has been tested by comparing the API measured from this device to the current API measured by DOE at several locations. Based on the results from the experiment, this air quality measurement system is proved to be reliable and efficient.

Proximity Sensor Detects An Object When The Object Approaches Within The Detection Range And Boundary Of The Sensor. Proximity Sensor Includes All The Sensor That Perform Non Contact Detection In Comparison To Sensors Such As Limit Switch, That Detect The Object By Physically Contacting Them. It is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity sensor's target. Different proximity sensor targets demand different sensors. For example, a capacitive or photoelectric sensor might be suitable for a plastic target; an inductive proximity sensor always requires a metal target. The maximum distance that this sensor can detect is defined "nominal range". Some sensors have adjustments of the nominal range or means to report a graduated detection distance. Proximity sensors can have a high reliability and long functional life because of the absence of mechanical parts and lack of physical contact between sensor and the sensed object. Proximity sensors are commonly used on smart phones to detect (and skip) accidental touch screen taps when held to the ear during a call.[1] They are also used in machine vibration monitoring to measure the variation in distance between a shaft and its support bearing. This is common in large steam turbines, compressors, and motors that use sleeve-type bearings. A change in the sensor's electric or magnetic field can also be used to determine proximity.
Smart materials are designed materials that have one or more properties that can be significantly changed in a controlled fashion by external stimuli, such as stress, temperature, moisture, pH, electric or magnetic fields.

Global warming is referred to the rise in average surface temperatures on earth primarily due to the Greenhouse Gases (GHG) emissions such as Carbon Dioxide (CO ). Monitoring the emissions, either direct or indirect from the industrial processes, is important to control or to minimize their impact on the environment. Most of the existing environmental monitoring system is being designed and developed for normal environment monitoring. Hence, the aim of this project is to develop industrial CO 2 emission monitoring system which implements industrial Open Platform Communications (OPC) protocol in an embedded microcontroller. The software algorithm based on OPC data format has been designed and programmed into the Arduino microcontroller to interface the sensor data to any existing industrial OPC compliant Supervisory Control and Data Acquisition (SCADA) system. The system has been successfully tested in a lab with the suitable environment for real-time CO emissions measurement. The real-time measurement data has been shown in an industrial SCADA application which indicates successful implementation of the OPC communications protocol.

Material management in construction – a case studyeSAT Journals
Abstract
The objective of the present study is to understand about all the problems occurring in the company because of improper application
of material management. In construction project operation, often there is a project cost variance in terms of the material, equipments,
manpower, subcontractor, overhead cost, and general condition. Material is the main component in construction projects. Therefore,
if the material management is not properly managed it will create a project cost variance. Project cost can be controlled by taking
corrective actions towards the cost variance. Therefore a methodology is used to diagnose and evaluate the procurement process
involved in material management and launch a continuous improvement was developed and applied. A thorough study was carried
out along with study of cases, surveys and interviews to professionals involved in this area. As a result, a methodology for diagnosis
and improvement was proposed and tested in selected projects. The results obtained show that the main problem of procurement is
related to schedule delays and lack of specified quality for the project. To prevent this situation it is often necessary to dedicate
important resources like money, personnel, time, etc. To monitor and control the process. A great potential for improvement was
detected if state of the art technologies such as, electronic mail, electronic data interchange (EDI), and analysis were applied to the
procurement process. These helped to eliminate the root causes for many types of problems that were detected.

Life cycle cost analysis of overlay for an urban road in bangaloreeSAT Journals
Abstract
Pavements are subjected to severe condition of stresses and weathering effects from the day they are constructed and opened to traffic
mainly due to its fatigue behavior and environmental effects. Therefore, pavement rehabilitation is one of the most important
components of entire road systems. This paper highlights the design of concrete pavement with added mono fibers like polypropylene,
steel and hybrid fibres for a widened portion of existing concrete pavement and various overlay alternatives for an existing
bituminous pavement in an urban road in Bangalore. Along with this, Life cycle cost analyses at these sections are done by Net
Present Value (NPV) method to identify the most feasible option. The results show that though the initial cost of construction of
concrete overlay is high, over a period of time it prove to be better than the bituminous overlay considering the whole life cycle cost.
The economic analysis also indicates that, out of the three fibre options, hybrid reinforced concrete would be economical without
compromising the performance of the pavement.

Laboratory investigation of expansive soil stabilized with natural inorganic ...eSAT Journals
Abstract
Soil stabilization has proven to be one of the oldest techniques to improve the soil properties. Literature review conducted revealed
that uses of natural inorganic stabilizers are found to be one of the best options for soil stabilization. In this regard an attempt has
been made to evaluate the influence of RBI-81 stabilizer on properties of black cotton soil through laboratory investigations. Black
cotton soil with varying percentages of RBI-81 viz., 0, 0.5, 1, 1.5, 2, and 2.5 percent were studied for moisture density relationships
and strength behaviour of soils. Also the effect of curing period was evaluated as literature review clearly emphasized the strength
gain of soils stabilized with RBI-81 over a period of time. The results obtained shows that the unconfined compressive strength of
specimens treated with RBI-81 increased approximately by 250% for a curing period of 28 days as compared to virgin soil. Further
the CBR value improved approximately by 400%. The studies indicated an increasing trend for soil strength behaviour with
increasing percentage of RBI-81 suggesting its potential applications in soil stabilization.
Influence of reinforcement on the behavior of hollow concrete block masonry p...eSAT Journals
Abstract
Reinforced masonry was developed to exploit the strength potential of masonry and to solve its lack of tensile strength. Experimental
and analytical studies have been carried out to investigate the effect of reinforcement on the behavior of hollow concrete block
masonry prisms under compression and to predict ultimate failure compressive strength. In the numerical program, three dimensional
non-linear finite elements (FE) model based on the micro-modeling approach is developed for both unreinforced and reinforced
masonry prisms using ANSYS (14.5). The proposed FE model uses multi-linear stress-strain relationships to model the non-linear
behavior of hollow concrete block, mortar, and grout. Willam-Warnke’s five parameter failure theory has been adopted to model the
failure of masonry materials. The comparison of the numerical and experimental results indicates that the FE models can successfully
capture the highly nonlinear behavior of the physical specimens and accurately predict their strength and failure mechanisms.

Influence of compaction energy on soil stabilized with chemical stabilizereSAT Journals
Abstract
Increase in traffic along with heavier magnitude of wheel loads cause rapid deterioration in pavements. There is a need to improve
density, strength of soil subgrade and other pavement layers. In this study an attempt is made to improve the properties of locally
available loamy soil using twin approaches viz., i) increasing the compaction of soil and ii) treating the soil with chemical stabilizer.
Laboratory studies are carried out on both untreated and treated soil samples compacted by different compaction efforts. Studies
show that increase in compaction effort results in increase in density of soil. However in soil treated with chemical stabilizer, rate of
increase in density is not significant. The soil treated with chemical stabilizer exhibits improvement in both strength and performance
properties.

Abstract
Water resources projects are inherited with overlapping and at times conflicting objectives. These projects are often of varied sizes
ranging from major projects with command areas of millions of hectares to very small projects implemented at the local level. Thus,
in all these projects there is seldom proper coordination which is essential for ensuring collective sustainability.
Integrated watershed development and management is the accepted answer but in turn requires a comprehensive framework that can
enable planning process involving all the stakeholders at different levels and scales is compulsory. Such a unified hydrological
framework is essential to evaluate the cause and effect of all the proposed actions within the drainage basins.
The present paper describes a hydrological framework developed in the form of a Hydrologic Information System (HIS) which is
intended to meet the specific information needs of the various line departments of a typical State connected with water related aspects.

Evaluation of punching shear in flat slabseSAT Journals
Abstract
Flat-slab construction has been widely used in construction today because of many advantages that it offers. The basic philosophy in
the design of flat slab is to consider only gravity forces; this method ignores the effect of punching shear due to unbalanced moments
at the slab column junction which is critical. An attempt has been made to generate generalized design sheets which accounts both
punching shear due to gravity loads and unbalanced moments for cases (a) interior column; (b) edge column (bending perpendicular
to shorter edge); (c) edge column (bending parallel to shorter edge); (d) corner column. These design sheets are prepared as per
codal provisions of IS 456-2000. These design sheets will be helpful in calculating the shear reinforcement to be provided at the
critical section which is ignored in many design offices. Apart from its usefulness in evaluating punching shear and the necessary
shear reinforcement, the design sheets developed will enable the designer to fix the depth of flat slab during the initial phase of the
design.
Keywords: Flat slabs, punching shear, unbalanced moment.

Estimation of surface runoff in nallur amanikere watershed using scs cn methodeSAT Journals
Abstract
The development of watershed aims at productive utilization of all the available natural resources in the entire area extending from
ridge line to stream outlet. The per capita availability of land for cultivation has been decreasing over the years. Therefore, water and
the related land resources must be developed, utilized and managed in an integrated and comprehensive manner. Remote sensing and
GIS techniques are being increasingly used for planning, management and development of natural resources. The study area, Nallur
Amanikere watershed geographically lies between 110 38’ and 110 52’ N latitude and 760 30’ and 760 50’ E longitude with an area of
415.68 Sq. km. The thematic layers such as land use/land cover and soil maps were derived from remotely sensed data and overlayed
through ArcGIS software to assign the curve number on polygon wise. The daily rainfall data of six rain gauge stations in and around
the watershed (2001-2011) was used to estimate the daily runoff from the watershed using Soil Conservation Service - Curve Number
(SCS-CN) method. The runoff estimated from the SCS-CN model was then used to know the variation of runoff potential with different
land use/land cover and with different soil conditions.
Keywords: Watershed, Nallur watershed, Surface runoff, Rainfall-Runoff, SCS-CN, Remote Sensing, GIS.
Estimation of morphometric parameters and runoff using rs & gis techniqueseSAT Journals
Abstract
Land and water are the two vital natural resources, the optimal management of these resources with minimum adverse environmental
impact are essential not only for sustainable development but also for human survival. Satellite remote sensing with geographic
information system has a pragmatic approach to map and generate spatial input layers of predicting response behavior and yield of
watershed. Hence, in the present study an attempt has been made to understand the hydrological process of the catchment at the
watershed level by drawing the inferences from moprhometric analysis and runoff. The study area chosen for the present study is
Yagachi catchment situated in Chickamaglur and Hassan district lies geographically at a longitude 75⁰52’08.77”E and
13⁰10’50.77”N latitude. It covers an area of 559.493 Sq.km. Morphometric analysis is carried out to estimate morphometric
parameters at Micro-watershed to understand the hydrological response of the catchment at the Micro-watershed level. Daily runoff
is estimated using USDA SCS curve number model for a period of 10 years from 2001 to 2010. The rainfall runoff relationship of the
study shows there is a positive correlation.

Effect of variation of plastic hinge length on the results of non linear anal...eSAT Journals
Abstract The nonlinear Static procedure also well known as pushover analysis is method where in monotonically increasing loads are applied to the structure till the structure is unable to resist any further load. It is a popular tool for seismic performance evaluation of existing and new structures. In literature lot of research has been carried out on conventional pushover analysis and after knowing deficiency efforts have been made to improve it. But actual test results to verify the analytically obtained pushover results are rarely available. It has been found that some amount of variation is always expected to exist in seismic demand prediction of pushover analysis. Initial study is carried out by considering user defined hinge properties and default hinge length. Attempt is being made to assess the variation of pushover analysis results by considering user defined hinge properties and various hinge length formulations available in literature and results compared with experimentally obtained results based on test carried out on a G+2 storied RCC framed structure. For the present study two geometric models viz bare frame and rigid frame model is considered and it is found that the results of pushover analysis are very sensitive to geometric model and hinge length adopted. Keywords: Pushover analysis, Base shear, Displacement, hinge length, moment curvature analysis
Effect of use of recycled materials on indirect tensile strength of asphalt c...eSAT Journals
Abstract
Depletion of natural resources and aggregate quarries for the road construction is a serious problem to procure materials. Hence
recycling or reuse of material is beneficial. On emphasizing development in sustainable construction in the present era, recycling of
asphalt pavements is one of the effective and proven rehabilitation processes. For the laboratory investigations reclaimed asphalt
pavement (RAP) from NH-4 and crumb rubber modified binder (CRMB-55) was used. Foundry waste was used as a replacement to
conventional filler. Laboratory tests were conducted on asphalt concrete mixes with 30, 40, 50, and 60 percent replacement with RAP.
These test results were compared with conventional mixes and asphalt concrete mixes with complete binder extracted RAP
aggregates. Mix design was carried out by Marshall Method. The Marshall Tests indicated highest stability values for asphalt
concrete (AC) mixes with 60% RAP. The optimum binder content (OBC) decreased with increased in RAP in AC mixes. The Indirect
Tensile Strength (ITS) for AC mixes with RAP also was found to be higher when compared to conventional AC mixes at 300C.
Keywords: Reclaimed asphalt pavement, Foundry waste, Recycling, Marshall Stability, Indirect tensile strength.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
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!

Abstract
This review article focuses on the various environment monitoring systems developed over the years. The development of any
monitoring system is dependent on certain key factors namely cost of the system, energy efficiency of the system, signal to noise
ratio, interference rejection during varying atmospheric conditions. The complexity of any system depends upon the number of
nodes the system requires to monitor, the more the number of nodes the more complex structure becomes. If we use smart sensor
network with each node independently functioning and transmitting data to one parent node that performs required processing the
complexity decreases.

1. INTRODUCTION
Since India is still a developing country, major part of the
energy production is based on natural resources like coal,
natural gas etc., the energy produced from these resources is
not clean energy and leaves a highly toxic trail behind it.
The result of which is the pollutant concentration in
atmosphere has exceeded levels sustainable for good health
conditions. Today the emerging need is a monitoring system
that senses all the pollutants from the surroundings and
sends the data to control center to take necessary action.
According to United Nations Environmental Program the
buildings consume a humongous 40% of the all the energy
casing 35% of total pollution, if we carefully monitor such
areas we are hopeful that we can cut down major pollutants
from air. The major contributors of the greenhouse
emissions are carbon dioxide, oxides of sulphur and
nitrogen, suspended particulate matter and aerosols.
An uncontrolled and monitored system leads to health
hazards to the population living within or around that area.
So in order to improve the health conditions of the
population it is very crucial that we monitor and control
such pollutants.
Environment monitoring systems till now have been
implemented using centrally controlled system based on
various micro-controller technologies available.in such a
system the entire work load is on the central unit whereas
the nodes or the sensors do the work of sensing the stimuli
only. In case there is a malfunctioning of the central system
the entire monitoring system goes down, also if one of the
sensors malfunctions than till the time it is not restored the
system is affected whereas with a smart sensor network the
nearest similar node is switched on to prevent the
malfunctioning of the system, removing the latency that may
come in such cases.
Any environment monitoring system comprises of three
main modules which are Standard Transducer Interface
Module (STIM), Graphical User Interface and Transducer
Independent Interface. The STIM is used for gathering the
data, GUI is used for displaying the relevant data in
perceivable form and T.II is used to communicate this data
to the Network Capable Application Processor

2. METHODOLOGY
Fig 2: General Block of an Environment Monitoring System
By having a precise control of the environment one can
increase the standard of living of all individuals as many of
the health problems are created by these pollutants.
Controlling may also incorporate remote controlled devices
which are a boon for disabled and aged population of the
country but the problem is that the existing systems are very
costly and difficult to maintain as a result they are not
thought of as cost effective method of monitoring.
This paper takes into account the foundation of all such
systems and existing systems built on these foundations.
3. STANDARD TRANSDUCER INTERFACE
MODEL (STIM)
STIM is based on the IEEE 1451 standard which consists of
a collection of Transducer Electronic Data Sheets,
transducer independent interface and connection protocol
between the network and system. It is desired that a
transducer should be such that it not only senses the
stimulus but also conditions the signal so that the control
system can easily interpret reducing the work load on the
system.
Fig 3: An STIM Model
3.1 Sensor Array
Sensor is any device that senses a particular stimulus only
and provides an output in the form of an electrical signal.
A) Gas Sensor: This category of the sensors is most
difficult to fabricate and use in any system as the
output of such sensor is in the form of analog signal
that varies depending upon the concentration the
gas in the area. A very precise translation of the
analog signal to electrical domain is required to
successfully implement the sensor. Some of the
sensors that are used are based on chemical
sensing, photo ionic sensing but the most
successful are the MEMS based sensors.
B) Temperature and Humidity Sensor: Recent
advances in these sensors have enabled us to
integrate the two on a single chip and also a signal
conditioner on the same chip as a result we get a
digital output from the SOC. The sensor is based on
a linear temperature coefficient of a metal for
temperature sensing and chemical ionic sensor for
the humidity sensing.
C) Light Sensor: Use of artificial lights bulbs, CFL
etc. is very important in any area but these are over
used at all times. A light sensor carefully monitors
the intensity of the light that is coming and
provides a digital output so that the lights can be
increased, decreased or turned off depending on
output signal. This sensor is based on photon
detection principle.
For a very large area a network of such sensors can be used
each communicating with the central command center
4. TRANSDUCER INDEPENDENT INTERFACE
TII takes into account the protocols or methods used for
communication of sensed data to the control center. Many
systems have been developed for the same depending upon

area to be covered and cost constraints, they may be both
wireless and wired.
A) Wired: In a wired system the sensors are connected
to the control center using wires the major
disadvantage of such system is the losses incurred
in wired transmission due to resistance of wire and
the cost of laying the wire. As a result over the
years this has become least preferred method of
developing a system.
B) Wireless: In a wireless system a number of
communication technologies can be used like radio
frequency, Bluetooth, infrared etc. All these
technologies have a built in error control module as
a result of which we get a far more reliable system
without the complication of the wired technology.
Fig 4: General Block of Wireless Network
5. NETWORK CAPABLE APPLICATION
PROCESSOR
NCAP is mode of representation of data in user readable
form. It consists of two components namely; support and
application part.
The support block consists of the network interface,
transducer interface and an operating system. The
application block consists of a Processor that gives an
appropriate output in form of display and may also control
the devices to take necessary actions based on the input
received.
NCAP may be in form of a computer, tablet, mobile device
etc.
6. MARKET AVAILABLE SYSTEMS
Honey Well is the largest vendor of environment monitoring
and control systems. The cost of such systems is very high
and the complexity at which these systems work is great as a
result they are not much user friendly. They also require
timely service and maintenance as a result the overall cost
becomes totally unacceptable for a common man.
The technologies available are largely based on micro-
controller thereby limiting its network abilities in terms of
number of nodes that can be successfully implemented as
multiplexing a sensor pin would lead to latency of system
thus every sensor occupies one input pin and for a very large
area multiple controllers may be required finally increasing
the cost and maintenance.
Recently developed technology is based in using zigbee
modules, but not much research has been done in this field
largely because of the fact that it’s comparatively new.
Using a zig bee network largely simplifies the entire
operation as it has its own independent TII and can be easily
interfaced with a microprocessor running a Linux operating
system and later displaying the result on the internet making
the system accessible from anywhere around the world
increasing the ease of use.
7. CONCLUSION
Although the requirement of an environment monitoring
system is very important but still due to higher cost and
complexity it has been inaccessible for normal use. If
technologies like zigbee are further simplified than a
modular system can be achieved with a very low cost.
