Seamless Transitions between Grid-Connected and Stand-Alone Operations of Distributed Generation in Microgrids |
||||||||||||
Control of the Distributed Generation (DG) system is important in both grid-connected and standalone
modes and the system stability becomes very crucial during the transfer between these two modes. If the
system does not have a proper transfer procedure, severe transient voltages or currents will occur, which may
damage the entire system. A seamless transfer can ensure smooth operation and quick attainment of steady state.
In order to solve these transition problems, this paper presents the development and test of a control strategy for
DG capable of working in grid-connected and intentional islanding connection modes with seamless transitions
from both operational modes.

| Chemometrical Optimization for Fourier Transform Near Infrared Analysis of Sugar Brix in Cane Sugar Intermediate | ||||||||||||
Real-time evaluation of sugar quality requires determining the content of sugar brix in the steps of
the cane sugar process. Sugar brix is a key indicator for evaluating sugar quality. Fourier transform near infrared
(FTNIR) spectroscopy is a simple, rapid and non-destructive technology on the analysis of material contents. In
this study, the chemometric algorithm of parameter-combined tuning of Savitzky-Golay (SG) smoother and
Partial Least Squares (PLS) regression was utilized for FTNIR analysis of sugar brix content in sugarcane
clarified juice, an important intermediate product in cane sugar industry. The algorithms of combined
optimization of SG smoother and PLS regression was achieved and the calibration models were established
optimized by screening the expanded 540 SG smoothing modes and the 1-30 latent valuables (LV). The
optimized models have high predictive accuracy. These results confirm that the combined optimization of SG
smoothing modes and PLS LVs is effective in the quantitative determination of sugar brix contents in sugarcane
clarified juice, and that the FTNIR spectroscopic technology with its chemometric algorithms have the potential
in the analysis of cane sugar intermediates.

| An Experimental Investigation on Effect of Elevated Temperatures on M35 grade Concrete | ||||||||||||
In the event of sudden fire break out, the concrete elements such as columns, beams etc. are
subjected to extreme temperatures. The assessment of their performance after fire becomes necessary to decide
upon its fitness and required repair measures. Hence, it is important to understand the changes in the concrete
properties due to its exposure to extreme temperatures. It is important to know the effect of elevated temperature
on the properties of concrete. In this project thesis work experimental investigation is carried out to study the
effects of elevated temperatures on the compressive strength of normal concrete and on concrete by partial
replacement of cement with various percentages of fly ash. In the present study a concrete mix M35 and is taken.
In the normal concrete, cement is replaced with (0, 5, 10, 15, 20 and 25%) fly ash.The compressive strength of
concrete with various percentages of fly ash (0%to 25%) are subjected to temperatures (400 to 6000C), for
different time periods (30 and 60min) which were tested for 28 days and 56 days of curing. The samples are
cured in water and later exposed to various temperatures with various time periods. After heating the samples in
electrical furnace to the desired temperatures .They are allowed to cool to the room temperatures and tested
under compression. The average of the readings obtained is recorded and presented in various tables. This study
shows that the compressive strength of fly ash (0%to 10%) concrete is more than the normal concrete at room
temperatures and elevated temperatures and also compared to compressive strength of fly ash (15%to 25%)
concrete.

| VHDL Implementation of Scan-to-Scan Discriminator for the Detection of Marine Targets | ||||||||||||
For an operational radar, backscatter of the transmitted signal by the elements of the sea surface
often places severe limits on the detect ability of returns from ships, missiles, navigation buoys, and other
targets sharing the radar resolution cell with the sea surface. These interfering signals are commonly referred to
as sea clutter, or sea echo. Maritime surveillance radar experiences serious limitations imposed on their
performance by unwanted sea clutter.
In the marine environment, sea clutter might occur at a random position in one scan but not in the next or subsequent scans. In contrast, targets will appear from scan to scan with essentially the same amplitude. The scan-to-scan discriminator eliminates "spiky" clutter by using one of the 3 approaches. They are: 1. Fixed Threshold. 2. Cell Averaging Constant False Alarm Rate (CA- CFAR). 3. Clutter Map. The output of the scan-to-scan discriminator is then used to tag the speed of small marine targets and gating approach is used to tag the speed of large marine targets. The simulation waveforms are obtained using ModelSim-Altera10.1d Radar, scan-to-scan discriminator, sea clutter, fixed threshold, clutter map, CA-CFAR.

Replacement of Fine Aggregate with Local available Soil |
||||||||||||
Cement, sand and aggregate are basic needs for any construction industry. Sand is a prime material
used for preparation of mortar and concrete and which plays a major role in mix design. Now a day's erosion of
rivers and considering environmental issues, there is a scarcity of river sand. The non-availability or shortage of
river sand will affect the construction industry; hence there is a need to find the new alternative material to
replace the river sand, such that excess river erosion and harm to environment is prevented. Many researchers
are finding different materials to replace sand and one of the major materials is local available soil. Using
different proportion of this available soil along with sand the required concrete mix can be obtained. This paper
presents a review on the study of replacement of fine aggregate with local available soil with different
percentages (10%,20%,30%,40%,50% & 60%). Of all the trail mixes, the optimum replacement of soil with
sand was found to be 30%.

Security and Privacy Consideration for Internet of Things in Smart Home Environments |
||||||||||||
Internet Of Things(IOT) has emerged as a trustworthy technology to improve the quality of life in
smart homes through offering various automated, interactive and comfortable services. Sensors integrated at
different places in homes, offices, and even in clothes, equipment, and utilities are used to sense and monitor
owners' positions, movements, required signs, valuable usage, temperature and humidity levels of rooms, etc.
Along with sensing and monitoring capabilities, sensors cooperate and communicate with themselves to deliver;
share and process sensed information and help real-time decision making procedures through activate suitable
alerts and actions. However, ensuring privacy and providing enough security in these required services provided
by IOTs is a major issue in smart home environments. In this paper, we examine the privacy and security
challenges of IOTs and survey its possibilities for smart home environments. We discuss the unique
characteristics that differentiate a smart environment from the rest, elaborate on security and privacy issues and
their respective solution measures. A number of challenges and interesting research issues appearing from this
study have been reported for further analysis.

Assessment of Heavy Metals in Nnewi under Ground Water |
||||||||||||
The Assessment of heavy metals distribution and their likely adverse effects in underground
resources of Nnewi town of Anambra State within the sedimentary basin of south eastern Nigeria due to
industries has been studied. The instrument used for data collection includes topographic map, geologic map
aerial photograph, satellite image and fracture maps of Anambra drainage Basin. Ten (10) under ground water
samples from borehole, springs and hand dug wells were collected, this was followed by laboratory studies of
the water samples for the identification of heavy metals present. The result of the analysis of ten(10) water
samples shows that chromium, copper, cadmium and zinc were observed to be high while orgon, mercury,
molybdenum, nickel, lead, zirconium were not detected. The findings also show that cadmium (cd) was not in
some places such as Nnewichi, Otollo and Umudim. Villages in Nnewi town shows an abnormal distribution of
high chromium (cr) copper (cu) and zinc (zn). Above permissible limit, Cadmium causes cancer of the lungs,
and high blood pressure, while chromium causes kidney damage, liver damage, circulatory and nerve tissue
damage. Copper causes anemia, intestinal irritation, while zinc causes growth retardation, delayed sexual
maturation, infection susceptibility and diarrhea. It was suggested that chemical analysis of water should be
carried out periodically in the area since groundwater is subject to seasonal changes.

A Proposed Solution to Secure MCC Uprising Issue and Challenges in the Domain of Cyber Security |
||||||||||||
The development of cloud computing and mobility,mobile cloud computing has emerged and
become a focus of research. By the means of on-demand self-service and extendibility, it can offer the
infrastructure, platform, and software services in a cloud to mobile users through the mobile network. Security
and privacy are the key issues for mobile cloud computing applications, and still face some enormous
challenges. In order to facilitate this emerging domain, we firstly in brief review the advantages and system
model of mobile cloud computing, and then pay attention to the security and privacy in the mobile cloud
computing. MCC provides a platform where mobile users make use of cloud services on mobile devices. The
use of MCC minimizes the performance, compatibility, and lack of resources issues in mobile computing
environment. By deeply analyzing the security and privacy issues from three aspects: mobile terminal, mobile
network and cloud, we give the current security and privacy approaches. The users of MCC are still below
expectations because of the associated risks in terms of security and privacy. These risks are playing important
role by preventing the organizations to adopt MCC environment. Significant amount of research is in progress in
order to reduce the security concerns but still a lot work has to be done to produce a security prone MCC
environment. This paper presents a comprehensive literature review of MCC and its security issues,challenges
and possible solutions for the security issues.

Bayesian approach for spare parts replenishment policies under uncertainties |
||||||||||||
The legislative constraints, the need to optimize the dismantling process, the introduction of recycled
parts on the spare parts market are reinforced since the systems in end-of-life phase have become increasingly
profitable. There are few works that treat recycled spare parts integration problem in economic models of
inventory control. These works do not consider uncertainty. In order to manage more realistically the inventory
control of spare parts, we propose a probabilistic model formalized by a Bayesian network. The model is used to
identify the best purchase policy. More precisely, it allows choosing the best proportions between new spare
parts (NSP) and recycled spare parts (RSP) by taking into account the traditional criteria of inventory control
and the availability of the spare parts on the market. The proposed method provides a decision-making tool for
manufacturers who are interested both in reducing the costs of stocks and guaranteeing a minimal availability in
an uncertain environment.

Transport in Nagpur is important due to Nagpur's strategic location in a central India. It is a fast
growing metrocity and is the third most populous city in Maharashtra after Pune and Mumbai. also one of the
country's most industrialized cities.
Due to increase in population as well as transportation Nagpur mahanager palica NMPL company formed which gives contract to Vansh Nimay Infraprojects (VNIL) to run city buses but due to increase in transportation and increase in population in Nagpur city it found that there is a numerous problem face by city buses to gave safe and efficient facility to public due to these public in Nagpur city were diverting towards the private transportation. So there is immediately need to improve public transportation which can improve by Bus Rapid Transit (BRT) system which is new transport system provide safety and mobility to road users. In these projects we show the Impact of public transportation system such as Conjunction, Delay, Incident, Increase traffic condition. For this various data of the existing public transportation (star bus ) is collected such as accident data, Problem face by people, traffic data collection for how star bus face the problem and extra time taken to reach destiny Public transport network, Bus Rapid Transit system, safety, star bus, Conjunction.

Spatial and temporal distribution of Nitrate (NO3 -) In groundwater of Rohtak municipality area. |
||||||||||||
The contamination of ground water has increased with rapid urbanization, agricultural inputs and
industrialization. In the last few decades the nitrate (NO3
-) pollution is on the increase in the urban areas.
Contamination of ground water with nitrate is mainly by the process of leaching due to high mobility of nitrate ions through soil. By mapping water quality using the decision support system like geographical information system (GIS), the data can be represented graphically in map and is useful for taking quick decision. The objective of present study was to monitor the spatial and temporal nitrate ion concentration in ground water of Rohtak city in pre monsoon, monsoon and post monsoon season of private ground water drinking sources, and graphical representation of data using GIS. The samples from the various colonies of Rohtak city showed nitrate range from 1.8 mg/l to 45mg/l. Most areas showed a ground water nitrate level within permissible limits of 45 mg/L (CPCB) how ever Village Samargopalpur had the highest nitrate concentration (79mg/L). Higher nitrate concentration was observed in area having history of agriculture use and open sewage, septic tanks, municipal solid waste and dairy waste dumps. In all the sampling sites the nitrate concentration was highest during the pre monsoon season. Nitrate toxicity; methaemoglobinaemia; ground water; ERDAS,GIS

A Study on Strength of Reinforced Flyash with Randomly Distributed Fibers |
||||||||||||
Flyash is a waste produced from thermal power stations, which contributes to environmental
pollution. It is a waste material that can be utilized in construction of roads and embankments. Randomly
distributed fiber reinforced soils have recently attracted increasing attention in geotechnical engineering. One of
the most promising approaches in this area is use of flyash as a replacement to the conventional weak earth
material and fiber/coir as reinforcement will solve two problems with one effort i.e. elimination of solid waste
problem on one hand and provision of a needed construction material on other. Disposal of a variety of wastes
in an eco friendly way is the thrust area of today's research. This paper investigates to determine the optimum
percentage of waste plastics/coconut coir with flyash material by conducting direct shear and CBR tests. It was
observed that from the laboratory test results, the optimum percentage of waste plastics and coconut coir with
flyash material are 0.3% and 0.2% respectively and also flyash with waste plastics shows better performance as
compared to flyash with coconut coir.

An Investigation on the Performance Characteristics of a Centrifugal Compressor |
||||||||||||
The design and off-design performance characteristics of single stage centrifugal compressor
consisting of 12 vanes impeller interfacing with 11 vanes diffuser have been studied experimentally and
numerically. The impeller has been designed and developed with radial exit, 30o inlet blade angle (with
tangent), 77 mm diameter and the discharge volute considering constant mean flow velocity. The performance
of the compressor at varying capacity (60 to 120 % of design) by controlling the discharge valve and with the
variation of rotating speed (15000 to 35000 rpm) by regulating speed of the coupled gas turbine has been
conducted at the recently developed test rig. The numerical simulation has been done by adopting viscous
Reynolds Average Navier-Stokes (RANS) equations with and without Coriolis Force & Centrifugal Force in
rotating reference frame (impeller) and stationary reference frame (casing) respectively utilizing CFD software
Fluent 14. The flow around a single vane of impeller interfacing with single vane of diffuser, the rotational
periodicity and sliding mesh at the interfacing zone between rotating impeller and stationery diffuser are
considered. Non dimensional performance curves derived from experimental and numerical results are
presented and compared. The numerical results are found to match very closely with the experimented data near
the design point and deviation is observed at the both side of the designed operating point. Non-uniform
pressure profiles towards the impeller exit and strong cross flow from blade to blade are detected at low flow
operating conditions. Total pressure, static pressure and velocity distributions at design and off design
operation obtained from the CFD results are analysed and presented here.

The Effect of Structure -Soil Interaction on Eccentrically Loaded Frame |
||||||||||||
The interaction among structures, their foundations and the soil medium below the foundations alter
the actual behaviour of the structure considerably than what is obtained from the consideration of the structure
alone. Thus, a reasonably accurate model for the soil–foundation–structure interaction system with
computational validity, efficiency and accuracy is needed in improved design of important structures. The
framed structures are normally analyzed with their bases considered to be either completely rigid or hinged.
However, the foundation resting on deformable soils also undergoes deformation depending on the relative
rigidities of the foundation, superstructure and soil. Interactive analysis is, therefore, necessary for the accurate
assessment of the response of the superstructure.
In this thesis ABAQUS 6.8, a FEA (Finite Element Analysis) package is used for the analysis of a building frame founded on piles of 2 x 2 groups for a particular spacing of piles and for a particular L/d ratio of the pile. Type of foundation adopted is a free standing pile group. Soil condition is considered as infill dry sand in its loosest state. It is modeled as Winkler's foundation. The analysis is carried out to study the behaviour of the frame. A load transfer approach using linear springs (Lateral, Axial and Tip) is used for the analysis. Displacements, Rotations, Shear force and Bending moments are obtained by applying an eccentric load at 0.2(L/2) and 0.4(L/2) distance from the centre of the beam in the model frame. Applicability of ABAQUS6.8 a FEA package is verified by taking a worked out problem from J.Won et al (2006).

Performance Optimization of Diesel Engine with Chicken Waste Bio-diesel Blend Using Grey Rrelational Aanalysis |
||||||||||||
This paper presents an experimental study that include an application of the grey relational analysis
to determine the optimum factor level to obtain optimum multiple-performance characteristics of a diesel engine
run with different low-percentage chicken waste biodiesel-diesel blends. Grey relational analysis is used for data
analysis and four factors, namely, low-percentage chicken waste biodiesel-diesel blend, compression ratio,
injection timing and injection pressure were each considered at four levels. An L16 orthogonal array was used to
collect data for various engine performance related responses under constant engine loads. Results of
confirmation tests showed good agreement with predicted quantities. The results of the study revealed that the
combination of a blend consisting of 10% chicken waste biodiesel (B10), a compression ratio of 18, an injection
pressure of 220 bar and an injection timing of 19° bTDC produces maximum multiple performance of the diesel
engine.

Power Quality Enhancement through Dynamic Voltage Restorer using SRF Theory for Balanced and Unbalanced Loads |
||||||||||||
Power quality is certainly a major concern in the present era, it becomes especially important with
the introduction of sophisticated devices, whose performance is very sensitive to the quality of power supply.
Voltage sag is one of the severe power quality problems. This report addresses all the different aspects related to
voltage sag problem, such as its types, consequences and mitigation.
At present, a wide range of very flexible controllers, which capitalize on newly available power electronics components, are emerging for custom power applications. Among these, the distribution static compensator (DSTATCOM) and the dynamic voltage restorer (DVR) are most effective devices, both of them based on the VSC principle. A simple generalized algorithm based on basic synchronous reference-frame theory has been developed for the generation of instantaneous reference compensating voltages for controlling a DVR. This algorithm makes use of the fundamental positive sequence phase voltages extracted by sensing only two unbalanced and/or distorted line voltages. The algorithm is general enough to handle linear as well as nonlinear loads. The compensating voltages when injected in series with a distribution feeder by three single-phase Hbridge voltage-source converters with a constant switching frequency hysteresis band voltage controller tightly regulate the voltage at the load terminals against any power quality problems on the source side. A capacitorsupported DVR does not need any active power during steady-state operation because the injected voltage is in quadrature with the feeder current. MATLAB SIMULINK has been used in this project to perform the modeling and analysis of such controllers Comprehensive results is presented to assess the performance of each device as a potential custom power solution.

Traffic Safety Risks from Digital Advertising Billboards in Alabama |
||||||||||||
Increase in the number and sophistication of digital advertising billboard signs raises safety concerns
over potential contribution of such signs to traffic crashes. This paper describes a study that analysed 5 years of
historical crash records from Alabama to examine potential correlations between crash locations and their
proximity to digital advertising billboards. First, the research team identified locations of digital advertising
billboards along major limited-access facilities in Alabama and selected eight suitable sites for analysis. Eight
sites immediately downstream of the digital billboard locations were also considered as control sites. Then,
historical crash data were retrieved for all study sites and crash rates were calculated for digital advertising
billboards influence zones and adjacent control sites. Statistical analysis was employed to determine if
correlations can be established between crash occurrence and digital advertising billboard presence. The crash
data analyses revealed that the presence of digital billboards increased the overall crash rates at digital
advertising billboard influence zones by 29% compared to the study control sites. Moreover, sideswipe and
rear-end crashes were found to be overrepresented at digital advertising billboard influence zones compared to
control sites.

Remotely Controlled Automated Irrigation System |
||||||||||||
In the present scenario of farming a lot of automation has been included in order to get timely and
proper growing of crops. Due to land unavailability the farms are outside the city and the farm owners have to
travel large distances just to start the motors for irrigation. This technology helps to control the irrigation system
from a far away distance as it works on GSM technology. So by just sending a SMS (Short Message Service)
the farmer can look after his farm from his home itself. Another problem that mainly arises in farms which are
out of city is the frequent load shedding. To tackle this problem the GSM module that is present on the farm
notifies the farmer if the power supply is present or load shedding is going on. The failure causing devices are
monitored and are reported to the user. Main problem lies with the pumping motor. These are usually three
phase motors and can get damaged by several factors like over current, Short Circuit, Phase failure etc. This
technology helps to report all these problems directly to the user in an easy to understand graphical way by
using an Android application.

Load Rebalancing with Security for Hadoop File System in Cloud |
||||||||||||
[1]A file system is used for the organization, storage,[1]retrieval, naming, sharing, and protection of
files. Distributed file system has certain degrees of transparency to the user and the system such as access
transparency,[2] location transparency, failure transparency, heterogeneity, replication transparency etc.
[1][3]NFS (Network File System), RFS (Remote File Sharing), Andrew File System (AFS) are examples of Distributed file system. Distributed file systems are generally used for cloud computing applications based on [4] the MapReduce programming model. A MapReduce program consist of a Map () procedure that performs filtering and a Reduce () procedure that performs a summary operation. However, in a cloud computing environment, sometimes failure is occurs and nodes may be upgraded, replaced, and added in the system. Therefore load imbalanced problem arises. To solve this problem, load rebalancing algorithm is implemented in this paper so that central node should not overloaded. The implementation is done in hadoop distributed file system. As apache hadoop is used, security issues are arises. To solve these security issues and to increase security, [20] Kerberos authentication protocol is implemented to handle multiple nodes. This paper shows real time implementation experiment on cluster with result. Hadoop , Distributed File System, Load Rebalance , Kerberos, Cloud.

Internet of Things refer as interconnection of smart object, included from small coffee machine to
big car, communicate with each other without human interactions also called as Device to Device
communications. In current emerging world, all of the devices become smarter and can communicate with other
devices as well. With this rapid development of Internet of Things in different area like smart home, smart
hospital etc. it also have to face some difficulty to securing overall privacy due to heterogeneity nature. There
are so many types of vulnerability but here in this paper we put concentration on Distributed Denial of Service
attack (DDoS). DoS is attack which can block the usage for authentic user and make network resource
unavailable, consume bandwidth; if similar attack is penetrated from different sources its call DDoS. To prevent
from such attack it need mechanism that can detect and prevent it from attack, but due to small devices it has
limited power capacity. So that mechanism must be implemented at network entrance. In this paper we discuss
different DDoS attack and its effect on IoT.

A Survey on Securing TORA for Detecting and Protecting Against Sybil Attack in MANETs |
||||||||||||
Mobile Ad-hoc Network (MANET) is a quite challenging to ensures security because if it's open
nature, lack of infrastructure, and high mobility of nodes. MANETs is a fast changing network in a form of
decentralized wireless system. It requires a unique, distinct and persistent identity per node in order to provide
their security and also has become an indivisible part for communication for mobile device. In this phase of
dissertation, we have focused giving security to Temporally Ordered Routing Protocol Algorithm (TORA) from
Sybil attack. TORA is based on a family of link reversal algorithm. It is highly adaptive distributing routing
algorithm used in MANET that is able to provide multiple loop-free routes to any destination using the Route
Creation, Route Maintenance and Route Erasure functions. Sybil attack is a serious threat for wireless networks.
This type of attacker comes in the network and they start creating multiple identities. From that multiple identities they are disrupting the network by participating in communication with line breaking nodes. This cause's huge loss in network resources. These networks can be protected using network failure and firewall detection schemes for detecting the attack and minimizing their effects. Proposed approach is expected to secure TORA through the implementation. Performance factor of network would be taken into consideration in order to verify the efficiency of modified TORA in MANET environment. Mobile Ad-hoc Networks, TORA, Security, Sybil Attack.

Integration of Dg Units to Microgrid with Power Quaility Improvement Using Ann Techique |
||||||||||||
The proposed system presents power-control strategies of a Micro grid-connected hybrid generation
system with versatile power transfer. This hybrid system allows maximum utilization of freely available
renewable energy sources like wind and photovoltaic energies. For this, an adaptive MPPT algorithm along with
standard perturbs and observes method will be used for the system.
The inverter converts the DC output from non-conventional energy into useful AC power for the connected load. This hybrid system operates under normal conditions which include normal room temperature in the case of solar energy and normal wind speed at plain area in the case of wind energy. However, designing an optimal micro grid is not an easy task, due to the fact that primary energy carriers are changeable and uncontrollable, as is the demand. Traditional design and optimization tools, developed for controlled power sources, cannot be employed here. Simulation methods seem to be the best solution.

Experimental investigation and optimization study of combustion chamber geometry on performance and emission parameters using Rice bran biodiesel |
||||||||||||
An experimental investigation and optimization study of various piston geometries was conducted
on Greaves single cylinder direct injection compression ignition engine using straight diesel and blends of rice
bran biodiesel. The three combustion chamber geometries used in this study were Standard toroidal piston
(STP), hemispherical bowl piston (HBP) and Shallow toroidal re-entrant piston (STRP) at compression ratios of
18:1, 19.04:1 and 16.4:1 respectively. Rice bran biodiesel was derived by two step trans-esterification process
with an optimum yield of 86% with molar ratio 1:6, 06% of catalyst (KOH), 90 min reaction time and 65oC
reaction temperature. The performance parameters like brake specific energy consumption, brake thermal
efficiency and the emission parameters like carbon monoxide, unburned hydrocarbons and oxides of nitrogen
were analysed in detail. It was noticed that the BSEC of STRP was 12.1% with diesel and 14.02% with B100
biodiesel blend. The brake thermal efficiency was also found to be improved with biodiesel blend with STRP on
comparison with STP and HBP. The carbon monoxide and hydrocarbon emission was found to decrease with
STRP geometry were as HBP exhibited negative improvement. NOx emission was also found to increase with
STRP.

Karal clay in the Far North Cameroon: Study on Behavioural Floor Structures |
||||||||||||
The north is known for its scorching heat and swelling clay which in the presence of water,
dramatical increase in water volume and by drying or even to crack [2] [5]. Many authors have addressed the
problems posed by this type of ground vis-à-vis the construction and especially the buildings. What exact type
of transport infrastructure can be built on these soils? It is to answer this question that we focus our research on
Karal clay, the main constituent of soil in the region of Far Northern Cameroon. Over 21,489 km of roads in
Cameroon in charge of the state, nearly 44.5% are in poor condition. The Far North Region of Cameroon is one
with the longest straight road in poor conditions. In about 2374 km of road, only 1% is in good condition, 20%
in fair condition and 79 in poor conditions [3] [8]. The damage seen on the N-1 Kousséri Maroua road in the
region of the Far North are related to a combination of stresses: it supports the traffic, the weather, the layer
thickness and the quality of materials that constitute it. All these stresses are associated in one way or another
with the clay soil blowing up known for its instability to participate in the degradation of these roads [3] [6]
[13]. The primary mission of this scientific work is to provide necessary information and capital on Karal clay,
mineralogy, and its behavior with respect to pavement structures in the Sahel. However, laboratory studies on
Karal clay, allowed better assessment of its physical, chemical and mineralogical characteristics. Armed with
these scientific findings it allow us to better understand the Karal clay and its behaviour on the ground in the
Sahel region, we have developed strategies to increase the profitability of road investments on swelling clay
soils. To achieve the expected results, we submitted samples of Karal clay testing of physical-chemicalmineralogical characterisation laboratory. It is in particular, the determination of the water content and organic
matter, the complete particle size analysis, determination of Atterberg limits, Proctor changed, testing
Californian Bearing Ratio of the oedometer test, the shear test straight to the box Casagrande, and finally the Xray
diffraction

Equilibrium Studies of Malachite Green from Aqueous Solution Using Corn Cob as Adsorbent |
||||||||||||
The objective of this work is the study of adsorption of dye solution which is a dye malachite green
using corn cob. Removal of this dye from aqueous solution using corn cob has been investigated. Liquid phase
adsorption experiments were conducted. Batch adsorption studies are Carried out by observing the effect of
experimental parameters, namely, pH, and amount of adsorbents, contact time and initial concentration.
Optimum conditions for dye removal are studied like pH value, contact time required, amount of adsorbent, initial concentration, etc. The results generated by this work can be used for determination of optimum conditions for adsorption of dye in aqueous solutions. Dye is present in mixture form in various Industrial effluents like Textile Industries, Sewage water, Water treatment plants. This work can have use in Design of adsorption columns for dyes removal. The Freundlich adsorption model assumes that adsorption takes place on heterogeneous surfaces. Adsorption increases with increase in pH. The adsorption of cationic dye is mainly influenced by the amount of negative charges in the solution which is actually influenced by the solution pH. At pH=2 there is net positive charge in the solution so adsorption is less whereas at pH=12there is increase in negative charges increasing adsorption of malachite green. Maximum adsorption was found to take place at pH=12. Adsorption tends to increase with contact time. At first the increase in adsorption is very rapid as there are lots of free sites for the adsorption to take place. Adsorption decreases at later stages till saturation is reached due to saturation of active sites. The optimum contact time for equilibrium was found to be 100 min. corn cob, adsorption, malachite green, dye, adsorbent.

Analysis of IT Monitoring Using Open Source Software Techniques: A Review |
||||||||||||
The Network administrators usually rely on generic and built-in monitoring tools for network
security. Ideally, the network infrastructure is supposed to have carefully designed strategies to scale up
monitoring tools and techniques as the network grows, over time. Without this, there can be network
performance challenges, downtimes due to failures, and most importantly, penetration attacks. These can lead to
monetary losses as well as loss of reputation. Thus, there is a need for best practices to monitor network
infrastructure in an agile manner. Network security monitoring involves collecting network packet data,
segregating it among all the 7 OSI layers, and applying intelligent algorithms to get answers to security-related
questions. The purpose is to know in real-time what is happening on the network at a detailed level, and
strengthen security by hardening the processes, devices, appliances, software policies, etc. The Multi Router
Traffic Grapher, or just simply MRTG, is free software for monitoring and measuring the traffic load
on network links. It allows the user to see traffic load on a network over time in graphical form.

An Intelligent Based Hybrid Generation Scheme Fed Active Compensation Scheme for PQ Features |
||||||||||||
Harmonic pollution of the power supply system has raisen significantly in recent years due primarily
to an increase of non-linear loads connected to the utility through residential, commercial and industrial
customers. They constitute a harmonic pollution source of the network, which generate many disturbances, and
disturb the optimal operation of electrical equipments. This paper, proposed a solution to eliminate the
harmonics introduced by the nonlinear loads in steady and in transients. It presents a predictive current control
strategy for achieving maximum benefits from these grid-interfacing inverters implementing conventional DC
link controller and intelligence controller, when installed in 3-phase 4-leg voltage source inverter(VSI). The
inverter is controlled to perform as a multi-function device by incorporating active power filter functionality.
The use of a four-leg voltage-source inverter allows the compensation of current harmonic components, as well as unbalanced current generated by three-phase nonlinear loads. Renewable energy resources (RES) are being increasingly connected in distribution systems utilizing power electronic converters. The compensation performance of the proposed active power filter and the associated hybrid PV/Wind system generation scheme with new control scheme is demonstrated to improve the power quality features is simulated using MATLAB/SIMULINK.

Performance Analysis of Image Enhancement Using Dual-Tree Complex Wavelet Transform and Nonlocal Means |
||||||||||||
Resolution enhancement (RE) schemes which are not based on wavelets has one of the major
drawbacks of losing high frequency contents which results in blurring. The discrete wavelet- transform-based
(DWT) Resolution Enhancement scheme generates artifacts (due to a DWT shift-variant property). A wavelet-
Domain approach based on dual-tree complex wavelet transform (DT-CWT) & nonlocal means (NLM) is
proposed for RE of the satellite images. A satellite input image is decomposed by DT-CWT (which is nearly
shift invariant) to obtain high-frequency sub bands. Here the Lanczos interpolator is used to interpolate the highfrequency
sub bands & the low-resolution (LR) input image. The high frequency sub bands are passed through
an NLM filter to cater for the artifacts generated by DT-CWT (despite of it's nearly shift invariance). The
filtered high-frequency sub bands and the LR input image are combined by using inverse DTCWT to obtain a
resolution-enhanced image. Objective and subjective analyses show superiority of the new proposed technique
over the conventional and state-of-the-art RE techniques.

Analysis of Existing Models & Proposed Cyber Crime Investigation Model |
||||||||||||
In current scenario cyber crime is increasing at exponential rate, as the technology is growing at
enormous speed hence the cyber crime investigation is becoming a tedious job without a proper framework.
There is a wide range of different types of cyber crime today which are prevailing in the society. Solution of each case requires is a complicated task. Till date the investigation models proposed by various researchers have some or the other shortfalls. They are somehow limited to certain types of cyber crime only and these models largely restrict themselves to the investigation of the crime scene and the evidence, and so are less extensive in their scope. These models provide overview of the general technical investigation activities. In this paper, a model has been proposed, named "cyber crime investigation model" which will capture a full scope of an investigation process and provide framed activity for every step. The proposed model focuses more into efficiency, accuracy and how to preserve the fragile evidence, its transport and storage.
