Author (s): Yanuar Haryanto, Buntara Sthenly Gan, Nanang Gunawan Wariyatno and Eva Wahyu Indriyati
Abstract:

Purbalingga, Indonesia, is regency with moderately high seism city potential requiring compliance with planning and implementation rules for earthquake-resistant structural systems. We evaluate the performance of a ten-story irregular apartment building model in Purbalingga due to the seismic load. It is necessarily conducted in order to provide information on impacts and mitigation strategies that should be implemented. The evaluation is performed based on seismic loads given in the 2002 and 2012 Indonesian National Standard (SNI) using linear static analysis, dynamic response analysis, and pushover analysis. Based on linear static analysis, the drift ratio decreases by an average of 34.42 and 32.61% for the X and Y directions respectively. Meanwhile, based on the dynamic response analysis, the drift ratio also decreases by an average of 30.74 and 27.33% for the X and Y directions respectively. In addition, the pushover analysis indicates that the performance of this apartment building model is still at Immediate Occupancy (IO) level, the post-earthquake damage state in which the building remains safe to occupy, essentially retaining the pre-earthquake design strength and stiffness of the structure. The risk of life-threatening injury as a result of structural damage is very low, and although some minor structural repairs may be appropriate, these would generally not be required prior to re-occupancy.

Author (s): Mehdi Taghizadeh and Sirus Sadughi
Abstract:

This Paper presents a practical way to improve signal bandwidth and resolution in a Sturdy Multi-Stage Noise-Shaping (SMASH) sigma delta modulator. In this way, the processing timing issue in the critical paths of the proposed architecture has been relaxed due to the shifting delay of the modulator loop filter of each stage to the its feedback path. The proposed Unity-STF SMASH architecture, which is realized with several efficient techniques, would be robust to circuit non-idealities such as finite op-amp DC gain.

Title: Green public procurement criteria for road infrastructures: State of the art and proposal of a weighted sum multi-criteria analysis to assess environmental impacts
Author (s): L. Moretti, P. Di Mascio and A. D. Andrea
Abstract:

In the last years, the attention to environmental issue is growing, demonstrating the interest to protect the nature and to better use the non-renewable resources. At international level, and especially in the European Community, for different trades, a wide production of voluntary documents and institutional acts proves the interest and the need for a green economy. An innovative approach may lead to the experience of Green Public Procurements (GPP), in order to protect the environment as a public interest and to promote technological developments. So far the experiences of GPP are limited, not entirely positive and in the field of road infrastructures almost entirely absent. Construction and maintenance of road infrastructures is objectively more complex than purchasing goods or services. The paper proposes the integration of the weighted sum multi-criteria analysis into existing procedures. The methodology needs for environmental labels related to materials, machines and works which contribute to the final product “road”. The labels are recognized at international level and consistent with procedures, conditions and criteria currently published in road tenders, therefore the approach can be followed to pursue the environmental sustainability of road infrastructures without compromising the economic attention.

Author (s): M. I. Ramli, M. Z. Nuawi, S. Abdullah, M. R. M. Rasani, M. F. Basar, M. A. F. Ahmad and K. K. Seng
Abstract:

Modal Analysis is a common practice to define parameters of structure under scientific view. Experimental Modal Analysis (EMA) is a well-known procedure to determine modal parameters. The usage of piezoelectric film sensor as viable and cost-saving device is indeed a need in this advance and sophisticated era. An experiment is conducted to determine modal parameters of aluminum 6061 (Al6061). Here, a free dynamic vibration analysis is conducted to obtain the parameters. Al6061 is chosen as the experiment component because of its wide application in manufacturing industries. Theoretically, if the component vibrates and produce frequency coherence with the natural frequency, resonance frequency will occur which can lead to structural failure. Modal analysis study is conducted by using both simulation and experimental methods. Simulation is conducted via ANSYS software while impact hammer testing is done for experimental work. Piezoelectric film and accelerometer are used as the sensor. The result obtained from simulation showed that frequencies for mode shape 1, 2 and 3 for square shape are 191.89Hz, 542.34Hz and 766.18Hz. The result gained from accelerometer showed that frequencies for mode shape 1, 2 and 3 for square shape are 195.00Hz, 557.00Hz and 865.00Hz. The result captured from piezoelectric film sensor appeared that frequencies for mode shape 1, 2 and 3 for square shape are 205.33Hz, 609.33Hz and 904.33Hz. The result obtained from simulation showed that frequencies for mode shape 1, 2 and 3 for circle shape were 134.60Hz, 324.73Hz and 727.52Hz. The result obtained from accelerometer showed that frequencies for mode shape 1, 2 and 3 for circle shape were 158.67Hz, 421.33Hz and 625.00Hz. Finally, the result captured from piezoelectric film sensor appeared that frequencies for mode shape 1, 2 and 3 for circle shape were 141.00Hz, 321.00Hz and 504.33Hz respectively. The equation of gradient for accelerometer and piezofilm is ya = 316.42x – 104.13 and yp = 309.63x – 43.20 respectively. Therefore, the relationship between the natural frequency of accelerometer and piezofilm for the square-shaped specimen is ya = 1.02yp – 59.98. The equation of gradient for accelerometer and piezofilm is ya = 270.55x – 134.82 and yp = 280.89x – 215.04 respectively. Therefore, the relation between the natural frequency of accelerometer and piezofilm for the circle-shaped specimen is ya = 0.96yp + 72.3. Both result showed the regression ratio of 1.02 and 0.96 which is approximately 1.0 and there was a good results agreement between simulation and experimental outcome.

Title: An overview on state-of-art and future application fields of BLDC motors: Design and characterization
of a PC-Interfaced driving and motion control system
Author (s): Paolo Visconti and Patrizio Primiceri
Abstract:

New generations of equipments must have better performances respect to the previous generations, such as higher efficiency, low power consumption, reduced electromagnetic interference, small dimensions, lightness and so on; all these improvements must be achieved while maintaining, at the same time, systems cost as low as possible. Brush-Less Direct Current (BLDC) motors, employed even more in the last years in many equipments in various application fields, present low maintenance costs, compact size, high reliability, efficiency, low power consumption and other optimum features, proposing themselves as excellent candidates for satisfying the stringent requirements mentioned previously. In this paper, after a detailed overview on the current and possible future application fields of BLDC motors, from home appliances, to automotive, industrial automation, medical equipments and robotic instrumentation, the design and realization of a driving and control system of a BLDC motor, with Hall sensors embedded, is presented. A BLDC motor is provided by permanent magnets on moving part (rotor) and windings on fixed part (stator); energized stator windings create electromagnetic poles and the rotor (equivalent to a bar magnet) is attracted by the energized stator phase. By using appropriate sequence to supply stator phases, a rotating field on stator is created and maintained. The lead between rotor and rotating field must be controlled to produce torque and this synchronization implies accurate knowledge of rotor position which is obtained by means of the embedded Hall effect sensors. The realized driving system is composed by three principal blocks: the control electronic board, the power driving board and the BLDC motor. By PC connected via USB with the driving board, the user can choose the motor rotation direction, set the desired rpm value and, by varying potentiometer value located on board, change the rotation speed. Different tests were performed for verifying the correct motor operation and the results show that all the employed devices, driving board, control board and BLDC motor, work properly.

Author (s): R. Thanuja and A. Umamakeswari
Abstract:

Network security is one of the primary concerned now days for large organizations. MANETs are deployed in challenging real-world environments for example, disaster management, civilian emergency operation and unmanned aircraft operation. Providing Security in this type of environment is the most challenging problems as the operation environment of such network is usually is difficult to decide. This will lead to any malicious activity that will affect the operation of the networks. Various modifications are being applied to IDS regularly to detect new attacks to handle them effectively. In this paper, we have designed a effective Intrusion Detection System (IDS) to detect the attacks in a MANET that uses modified fuzzy min max neural network in a effective manner. The aim of the proposed work is to improve the detection accuracy ratio and reduce the false positive rate. IDS is designed as a two phases technique, in which the first phase use the fuzzy min max neural network algorithm to train 60% data and test 40% data of the network. In the second phase, the modified fuzzy min max neural network algorithm is applied to 60% of train data +20% test data to form a new train data set and test the remaining 20% data collected. The proposed two phase intrusion detection method was evaluated using KDD cup data set. The experimental results showed that the proposed method is better than the other methods in terms of the detection rate, accuracy and reduced false positive rate.

Title: Design and analysis of tool wear characteristics during turning using deform 3D
Author (s): R. Rajesh, J. Lilly Mercy, S. Ravikumar and Akanksha Singh

Abstract:

Titanium and aluminium alloys are ubiquitously used in aerospace, automobile, chemical and medical applications due to their innate and characteristic properties of high strength to weight ratio, specific strength at elevated temperatures, corrosion and chemical resistance, creep and fatigue strength etc. Manufacture of accurate precision components from titanium alloys is a daunting task as the alloys are difficult to cut material due to the ingrained microscopic as well as macroscopic qualities such as low thermal conductivity, low modulus of rigidity, work hardening, high chemical reactivity with tool, built-up edge formation etc. during machining processes. Turning is one of the most widely used manufacturing techniques for producing circular shape from irregular shape in the real time industry applications and there are a large number of parameters to be investigated in this process. Predictions of important process variables of turning such as temperature, cutting forces and stress distributions play significant role on designing turning process parameter and optimizing cutting conditions. Therefore finite element deform 3d (FEA) and simulation comes as a handy tool to calculate and analyse the tool wear rate which in turn helps us save time and also leads to less material wastage. The tool bit base metal used is tungsten carbide over which a coating of three different materials namely Ti, Al2O3 and TiCN has been applied. Four factors that are -material, federate, speed, and depth of cut were taken into considerations at three different levels to get nine experiments which was then optimized by taguchi method to infer and analyse the best suitable parameter and condition for least amount of tool wear during turning operation.

Title: Behavior change in peat stabilized with fly ash and lime CaCO3 due to water infiltration
Author (s): Noor Endah Mochtar and Faisal Estu Yulianto
Abstract:

Stabilization method for fibrous peat is more beneficial than other soil improvement methods; it is cheaper and environmental friendly. Therefore, it has been developed continuously to obtain the optimum results. The previous study shows that 10% of admixture (lime CaCO3+fly ash) causes bearing capacity of the stabilized peat increases and its compression decreases. However, the study was carried out without considering the field condition where the area of stabilized peat was only as wide as the area that will be built. It means that the surrounding of the stabilized peat is still the original peat with very high water content. Consequently, water from the original peat will infiltrate into the stabilized peat area which has smaller voids and lower water content. Based on this consideration, the study was carried out to check the effect of water infiltration to the behavior of stabilized peat. This field condition was imitate in the laboratory model by putting the stabilized peat in the middle of the original peat. The admixture (lime CaCO3+fly ash) used was 10% and the stabilized peat parameter was observed until 180 days. The results show that behavior of stabilized peat w/o-infilt improve rapidly because formation of CaSiO3 gel is faster; however, in short curing period (90 days), its shear strength drops drastically and its compression becomes bigger. On the other hand, CaSiO3 gel formation of stabilized peat w-infilt is slow due to CaSiO3 gel formation is disturbed by water infiltration. As a result, its behavior improves slowly and the optimum results of the stabilized peat w-infilt reaches when the curing periods longer than 120 days. It also figures out that water infiltration gives a good effect to the behavior of stabilized peat.

Title: Evaluation of Power System Restoration Indices using Krill Herd algorithm based optimized PI+ controller for a restructured power system with facts devices
Author (s): K. Chandrasekar, B. Paramasivam and I. A. Chidambaram
Abstract:

This paper presents evaluation of Power System Restoration (PSR) Indices based on the Automatic Generation Control (AGC) assessment of two-area thermal reheat power system with FACTS devices in a restructured environment. These PSR indices indicate the ancillary service requirements to improve the efficiency of the physical operation of the power system with the increased transmission capacity in the network. In this study, a new control strategy the Proportional and Integral plus (PI+) controllers are designed using Krill Herd (KH) algorithm for solving AGC problem in power system. The PI+ controller uses a low-pass filter on the command signal to remove the transient’s response over shoot. In this way, the integral gain can be raised to higher values and PI+ controller is useful in applications for AGC loop. The recent advances in power electronics have led to the development of the FACTS devices such as Thyristor Controlled Phase Shifter (TCPS) and Static Synchronous Series Compensator (SSSC) are capable of controlling the network condition in a very fast and economical manner. The proposed PI+ controllers are designed and implemented in two-area unequal interconnected reheat thermal power plants with FACTS devices are considered for simulation study and their optimum settings are obtained using KH algorithm employing Integral Square Error based fitness function. From the simulations results, the incorporation of FACTS devices can enhance the total transfer capability and decrease the line congestion and to ensure improved PSR Indices in order to provide good margin of stability.

There is a brand new measuring device that allows measuring the amount of force on each tooth of each roller bit in cooperation with nondestructive bottom hole, consisting of concentric steel rings, divided into two sectors. There was made a skid for realization of this method, which was intended for rolling drilling bit under pressure in bottom hole of measuring device. There is a method for measurement of forces, which effects on elements of rolling drilling bit. There is a substantiation about choice of object of research and results of made experiments and its statistical processing minimum required length of one test was determined and number of repeats of each test to obtain reliable results at a given confidence level and permissible measurement error. There was made an analysis, which showed cooperation schemes of one crown to bottom hole, and on the basis of which it was concluded that axial components of forces have a greater impact on the durability of drilling bit cutting structure than tangential. Therefore, only axial components were evaluated in selection of test mode. Optimal ranges of axial loads on bit and bit speeds were determined, and that allowed getting an objective picture of distribution of forces on drilling bit cutting structure. Developed method with using a computer allows getting a large amount of reliable information very quickly about how to download all elements of equipment of rolling drilling bits of various sizes in order to optimize the design of their cutting structure and gauntries.

Title: Energy detection based cooperative spectrum sensing system for emergency networks
Author (s): A. Hadi Fikri A. H., Paulson E. N., Rozeha A. Rashid, Kamaludin Mohamad Y. and Mohd. Adib Sarijari
Abstract:

During emergencies, a number of rescue teams come to the field and setup their own radio communication systems. If the deployed communication setup does not coordinate among themselves properly, they may interfere with each other when using the same RF channels known as co-channel interference. Spectrum sensing is the most important and complex job for cognitive radios. Cooperation among cognitive radio nodes is needed to enhance the sensing performance. In this paper, we present an experimental study of this solution. A Software Defined Radio comprising of GNU Radio and USRP were used to capture the signal samples to build a database profile of the spectrum condition. MATLAB communications toolbox was used to analyze the data and examine the spectrum pertaining to the condition in emergency networks. The benefits of cooperative spectrum sensing in avoiding co-channel interference during emergency situations are illustrated. Cooperation among cognitive spectrum sensing nodes operating at the same frequency improves the probability of detection, and the overall efficiency of the system. Results show that the cooperative sensing scheme outperforms the individual sensing approach. It can increases the probability of detection relative to the collected samples as the key performance indicator.

Abstract:

Titanium alloys found broad applications in aviation, chemical, and automotive sectors because of its lightweight, high-temperature strength, and high corrosion resistance. This research paper investigates the influence of machining variables on the surface roughness of the machined component in finish turning of titanium alloy Ti-6Al-4V. The finish turning experiments conducted on GEEDEE WEILER CNC lathe at different speeds (v), feed (f) and depth of cut (d). Uncoated tungsten carbide insert was used as the cutting tool. Taguchi L9 orthogonal array utilized to perform the experiments. After conducting each test, surface roughness measured using surfcom tester. The optimal machining variables that provide the smaller value of surface roughness is determined based on signal to noise ratio method. Analysis of variance (ANOVA) was accomplished to identify the most affecting machining variable on surface roughness. The experimental result shows that the feed was the most dominant variable that influences the surface roughness. From the ANOVA, the surface roughness in finish turning is strongly influenced by the feed rate followed by speed and depth of cut. The minimum surface roughness was obtained by the following optimal variables via speed 75 m/min, feed rate 0.1 mm/rev and depth of cut 0.25 mm.

In this paper, an Intelligent Water Drops (IWD) algorithm is proposed for task workflow scheduling with hyper-heuristic search for achieving better performance optimization for workflow distribution in computational grid environment. The challenge is to find the best matching resource among the available free resources for which a grid broker is used. A hyper heuristic search is performed which undergoes multiple rounds of searches for finding the best matching resource by imparting a specific point in time rule. Load balancing is achieved by computing the average computational power of all the resources and grouping the resources. This helps the system to assign various types of jobs to the resources, thus improving the computational efficiency. The performance parameters such as makespan, cost, deadline of jobs and number of searches for finding best optimal resource are considered for performance enhancement. The simulation results of Intelligent Water Drops based Hyper-heuristic algorithm is compared with few of the latest existing works and the proposed algorithm outperforms thus achieving performance optimization.

Title: Boundary optimization of Ground Glass Opacity in CT images of lung cancer
Author (s): Saravanan S., Selvakumar G., Amarnath C. and Manikandan S.
Abstract:

In computer aided diagnosis, pre-processing, segmentation, feature extraction and classification are the steps involved. For segmentation the boundary must be defined to get regional information inside the boundary. Ground Glass Opacity (GGO) has ill-defined boundary. Hence, there is a necessity to optimize the boundary of GGO. Once the boundary is optimized, feature extraction and classification of malignant and benign of the particular GGO becomes easy. Using Distance Regularized Level Set Evolution (DRLSE) and Active contour without edges independently, the contour is grown and compared with the model image. The model image was created using the expertise of a Radiologist, applying Mattes Mutual information method. The contour which gives maximum mutual information is concluded as the optimized boundary. Wavelet transform has already been proven its application in identifying pits and cracks of corrosion metals. The same analogy is applied in GGO so that the partly solid and liquid GGOs can be precisely classified as malignant or benign. After optimizing the ill-defined boundary of GGO features of wavelet transformation were extracted along with textural features of mean and variance. Skewness and kurtosis were neglected since they were negligibly small. It is shown that on comparing the growing contour with model image using mattes mutual information, the DRLSE method shows greater results, without leaking compared to Active contour without edges. After extraction of features from wavelet transformation and textural features classification as malignant and benign was done using learning vector quantization (LVQ). On finding the optimized boundary, it is easier to classify the ground glass opacity as diffuse finding or local finding. Hence taking two images where one is taken as malignant and other as benign classification was done as benign and benign by the classifier. The malignant have been identified as benign due to minimum number of images used in training.

Title: Frictional effect and load carrying capacity in porous inclined multi stepped composite bearings with couple stress fluids
Author (s): Nisha and Sundarammal Kesavan
Abstract:

This paper presents the frictional effect and load carrying capacity in porous inclined multi stepped composite bearings with couple stress fluids. The most general form of the modified Reynolds type equations derived for the squeeze film lubrication of the porous inclined multi stepped bearings and an expressions for pressure distribution, work load and frictional force is mathematically derived. These expressions can be utilized to obtain the performance characteristics of different types of geometry under consideration. The important parameters for discussing the behavior of bearing characteristics are the couple stress parameter , the percolation parameter ‘ß’ and the permeability parameter. The global system of equations was obtained for the bearing and solved using MATLAB iterative scheme. It is observed that there is a significant increase in the pressure distribution this will lead to an increase in load capacity for fluids with couple stress in comparison with Newtonian fluids and the coefficient of friction for inclined stepped composite bearing compared to other geometries. According to the results, the couple stress fluid as a lubricant improves the squeeze film characteristics and results in a longer bearing life.

Title: Power factor correction converters for BLDC motor drive system: A comparative evaluation
Author (s): P. Sarala, S. F. Kodad and B. Sarvesh
Abstract:

AC to DC conversion with the help of power electronic converters is very much used these days in many applications. Rectification of input supply is essential in many areas of engineering especially in motor drive applications. BLDC motor is fed with DC supply and need a rectifier to convert available AC supply to DC type. Rectification from input AC supply to DC output with simple diode bridge rectifier insists for an output capacitance for stiff DC output. The presence of capacitance at the output of DC side deteriorates source power factor and reduced power factor at source side can cause serious problems in the system. This phenomenon insists for power factor correction. Power factor correction using DC-DC converters is a general practice. This paper presents a comparative evaluation of different types of power factor correction converters for BLDC motor drive application. Power factor correction converters like current follower Buck converter, Bridgeless Buck converter and Hybrid Buck converters were presented in this paper for evaluation. The Simulink models and results are developed using MATLAB/SIMULINK software. Power factor angle between source voltage and source current was presented with all three converters and THD in stator current was also depicted.

Title: Design and analysis of novel high performance CMOS domino-logic for high speed applications
Author (s): Rajesh Kumar Patjoshi, Suvarsha, S. K. Irfan Ali, S. K. Mastan Basha and D. Anjum
Abstract:

Dynamic logic style is popular due to its fast processing speed and less power dissipation in high performance circuit design as compared to static CMOS logic style. However, dynamic logic has less noise tolerance and charge sharing problems and hence it is not widely accepted for all high speed applications. As a consequence, a domino logic circuit is proposed for applications such as high-speed adder, comparator and arithmetic and logic unit (ALU) design. Furthermore, the proposed domino logic circuit provides multi standard advantages such as less propagation delay, less power dissipation and high fan out capability. The proposed circuit is simulated and tested in T SPICE with 45 nm technology. Moreover, it is compared with other domino logic circuits in terms of power dissipation and propagation delay.

Abstract:

What you do today determines your tomorrow; not having an efficient disposal strategy today will lead to a trashy tomorrow. Noting and implementing a robust mechanism for disposal is what this paper aims at. This project works on an integrated sensing system which involves gathering details of parameters that help us in being aware of the condition of dustbin using sensors and updating the inputs received from the sensors to an IOT based server using Raspberry-pi so that that the information can be accessed from any remote device by waste handlers and from the information received by the waste handlers help them decide whether a particular area needs immediate cleaning or not and also if an area needs extra litter bins to be placed nearby or removal and relocating existing litter bins to other places where they are needed so as to handle waste effectively. Dustbins are fixed with sensors which are further interfaced with microcontroller and based on the information received from sensors it notifies the status of the bin to the municipal corporation. This results in automation of the process of waste management. The data thus collected can also be used in data analytics which helps in the precise estimation of the condition of bin beforehand.

Title: Fresh and hardened properties of nanosilica and microsilica contained self-consolidating concretes
Author (s):

Maan S. Hassan, Ikbal N. Gorgis and Ali A. Jaber

Abstract:

This study focuses on the effects of colloidal nanosilica (nS) on fresh and key hardened properties of SCCs in comparison with similar replacement values of the commonly used microsilica (mS). Two types of portland cement with low (type V) and moderate (type I) tricalciumaluminates (C3A) and three percentages of cement replacement with nS or mS. Fourteen concrete mixes were evaluated for flow, T50, V- funnel, J-ring and L-box as workability measurements; and compressive strength, splitting tensile strength and chloride resistance as hardened properties. Fresh properties results reveal that with equivalent percentages of cement replacement and super-plasticizer added, colloidal nS shows lower workability measurements compared to that of mS. This observation is consistence for both types of cement used. The use of nS enhanced all concretes compressive strengths compared to mS and control mixtures. The improvements were a function of nS dosages used. The enhancements in splitting tensile strengths, however, were more pronounced at lower nS dosage of 3%, which reflect the sensitivity of tensile properties to the binder replacement effects. The remarkable improvements in chloride resistance performance for concretes contained nS, correlate with the compressive strength results and indicating for better pore structure characteristics.

Title: Home automation using IoT linked with Face book facial recognition
Author (s):

Abhigyan Singh, Devbrat Rath, Keshav Bansal and Vidhyapathi C. M.

Abstract:

In recent years, the world has seen a lot of progress in automated home systems. The existing home automation systems are basic: turning switches on/off, etc. over the Internet. But this leaves a lot to be desired in the Home Security department. While there are systems that let you view your security camera feed, this is highly time consuming and counter-productive. Pressing of buttons also needs to be replaced with a voice-to-text and a text-to-voice feedback system to enable ease of access. Also, using the Internet servers to control devices makes the systems prone to server-related issues like lag when the servers are overloaded, etc. Hence, there is a need to access the devices in Real Time. This paper deals with all of the above mentioned issues. It deals with the idea of using PubNub Networks as a real time operator, and using facial recognition interfaced with the Face book account of the home owner to make the surveillance of homes more time saving and accurate, and usage of a mobile application-based interactive feedback system.

Author (s):

S. Madiwale, A. Karthikeyan, V. Bhojwani and S. Chougule

Abstract:

Non conventional, alternative and as different energy source of energy, biodiesel attracted many scientists and researchers to consider him as an alternative fuel for automotive sector in last few years by large. Biodiesel is an oxygenated fuel, which contains 10 % to 11% oxygen, no aromatics, higher cetane number and reduce harmful pollutants from engine exhaust. Higher viscosity, higher flashpoint, poor cloud point, poor pour point and poor cold filter plugging point of pure biodiesel limits its direct usage as fuel in the diesel engine. So it is required to prepare the blend of biodiesel /diesel with addition of ethanol as an additive in order to improve hot flow and cold flow properties of the blend. Improved hot flow and cold flow properties will enhance engine performance, combustion and exhaust emissions. In the present study feedstock of cottonseed biodiesel/diesel blend is used as fuel with the addition of 5% of ethanol as an additive. Blend properties were investigated as per IS 1448 standards. Experimental investigations were carried out on single cylinder diesel engine with eddy current dynamometer. Experimental investigation shows that addition of ethanol improves kinematic viscosity by 7% .cloud point by 9%, and pour point by 10% but density was increased by 3% and calorific value decreased by 9% .Engine performance , combustion characteristics and reduction in emissions , are improved drastically by addition of an ethanol as an additive in the cottonseed biodiesel/diesel blend . Improved hot flow and cold flow properties , improved combustion , improved performance and reduced emissions proves that cottonseed oil biodiesel/diesel blend with ethanol as an additive stands as an alternative fuel for diesel engine.

Title: A blind zone alert system based on intra-vehicular wireless sensor networks
Author (s):

Shubham Kumar Vashisth, Avneet Shrivastava, M. Shanmugasundaram and Sundar S.

Abstract:

The aim of this project is to reduce number of wires in vehicle and alert the driver of blind zone collision. Because of the expanding number of sensors sent in current vehicles, intra-vehicular remote sensor systems (IVWSNs) have as of late gotten a great deal of consideration in the car industry, as they can diminish the measure of wiring tackle inside a vehicle. By evacuating the wires, auto producers can diminish the heaviness of a vehicle and enhance motor execution, mileage, and dependability. Notwithstanding these immediate advantages, an IVWSN is an adaptable stage that can bolster other vehicular applications too. An illustration application, known as a side visually impaired zone caution (SBZA) framework, which screens the visually impaired zone of the vehicle and cautions the driver in a convenient way to avoid impacts, is talked about in this paper. The execution of the IVWSN-based SBZA framework is assessed through genuine investigations led on two test vehicles. Our outcomes demonstrate that the proposed framework can accomplish roughly 95%-99% location rate with under 15% false alert rate. Contrasted and business frameworks utilizing radars or cameras, the primary advantage of the IVWSN-based SBZA is significantly lower cost.

Title: Characteristic of wavelength division multiplexing passive optical network
Author (s): M. Harshavardhan, A. V. Sumanth, B. Jagadeesh and Revathi S.
Abstract:

This paper is the first to demonstrate and simulated a simple and systematic transfer matrix (T-matrix) method for analyzing the accumulated effects of Rayleigh Backscattering (RB) and Fresnal reflection (FR) crosstalk on signal transmission in bidirectional single-fiber WDM-PON systems for the conventional (usually 20 km transmission without any amplification in remote node) and comparing with the analytical methods. Secondly by using analytical method we are going to analyse the three cases for long-reach WDM-PONs (100km by utilizing optical amplifier to enhance the power budget) in the first case the best crosstalk-to-signal (C/S) is achieved when the Remote Node (RN) is placed either near to the Central office (CO) or Optical Network Unit (ONU) section. And in the second case, we are going to achieve the best effective crosstalk-to-signal (C/S) ratio when the Remote Node (RN) gain is placed at the middle of transmission link. And in the third case, the crosstalk-to-signal (C/S) ratio gets worse nearly by 1.5 dB in the presence of a strong reflection (r = 30 dB). Eventually if the FR is increased by the smaller reflectivity and therefore EDFA gain must be exaggerated, the crosstalk-to-signal (C/S) ratio will even get worse when EDFA is placed near to ONU section. This happens due to the reamplification and re-modulation feedbacks of back reflections that may occur in the Transmission of the signal at Remote Node (RN). This transfer matrix method is efficient, powerful (when comparing with the analytical methods). Its accuracy is verified for straight forward system architectures and then applied for complex architectures of long-reach hybrid WDM-PONs.

Title: Geomechanical characterization of potential Roseneath shale gas, Cooper basin, Australia
Author (s): Omer Iqbal, Maqsood Ahmad and A. P. Askury Abd Kadir
Abstract:

Roseaneath and Murteree shale in Cooper basin, South Australia are proven seal, source as well as shale gas reservoir rock. Source rock characterization as a potential gas requires extensive understanding about the geomechanical properties for optimization of stimulation treatment and in order to avoid well bore instability and sand production during drilling and completion stages. Fifteen samples were selected from Moomba 191 well (depth 8473--8475 ft) drilled in Cooper Basin by DSD, Australia. The Triaxial compression and unconfined compression tests were performed on samples in order to find static geomechanical properties. The wireline logs like sonic and density were used to find dynamic mechanical properties. The calibrations were carried out between static and dynamic parameters in order to get reliable calibrated values. The 1-D Mechanical Earth Model (MEM) was developed based on elastic parameters (Young’s modulus, Poison’s ratio), failure parameters (Cohesion, internal friction angle, compressive strength and tensile strength), in-situ stresses, pore pressure and mud weight. The calibrated Young’s modulus and Poison’s ratio were ranging from 15 GPa to 30 GPa and 0.20 to 0.3 respectively. Brittleness analysis (BI) (ranges from 0.2-0.78) exhibited brittle and ductile layers within the whole shale interval. The Brittle index (BI), Young’s modulus and poison’s ratio on brittle layers were range from 0.4 to 0.78, greater than 25 GPa and <0.3 respectively for brittle layers. Based on failure parameters, insitue stresses and mud weight three possible locations for wellbore breakouts, fractures, has been identified where special considerations are needed to select the mud weight in order to avoid the problems i.e. sand production, wellbore instability. The strongest depths for minimum wellbore stability have been identified that have also high BI (0.6 to 0.69) and can be potential target for stimulation. Based on results, it has been concluded that this Roseneath shale interval of Moomba 191 well have many critical zones based on limits of upper and lower safe mud weight window where extra care need to be taken. The normal stress regime exhibited that fractures orientation will be perpendicular to minimum horizontal stresses.
