Authors: J. Jayapriya , Arock Michael
Published: June 2018

In bioinformatics, sequence alignment is the heart of the sequence analysis. Sequence can be aligned locally or globally depending upon the biologist's need for the analysis. As local sequence alignment is considered important, there is demand for an efficient algorithm. Due to the enormous sequences in the biological database, there is a trade-off between computational time and accuracy. In general, all biological problems are considered as computational intensive problems. To solve these kinds of problems, evolutionary-based algorithms are proficiently used. This chapter focuses local alignment in molecular sequences and proposes an improvised hybrid evolutionary algorithm using particle swarm optimization and cellular automata (IPSOCA). The efficiency of the proposed algorithm is proved using the experimental analysis for benchmark dataset BaliBase and compared with other state-of-the-art techniques. Using the Wilcoxon matched pair signed rank test, the significance of the proposed algorithm is explicated.

Authors: Ghosh Tarun Kumar , Das Sanjoy
Published: June 2018

Grid computing is a high performance distributed computing system that consists of different types of resources such as computing, storage, and communication. The main function of the job scheduling problem is to schedule the resource-intensive user jobs to available grid resources efficiently to achieve high system throughput and to satisfy user requirements. The job scheduling problem has become more challenging with the ever-increasing size of grid systems. The optimal job scheduling is an NP-complete problem which can easily be solved by using meta-heuristic techniques. This chapter presents a hybrid algorithm for job scheduling using genetic algorithm (GA) and cuckoo search algorithm (CSA) for efficiently allocating jobs to resources in a grid system so that makespan, flowtime, and job failure rate are minimized. This proposed algorithm combines the advantages of both GA and CSA. The results have been compared with standard GA, CSA, and ant colony optimization (ACO) to show the importance of the proposed algorithm.

Authors: Żurek Sławomir Jacek
Published: June 2018

This chapter presents various forms and functions of subversion referring to three literary examples which come from the recent Polish and German fiction. Subversion in this study is comprehended as a transgression of all textual boundaries; as such, it is present in a wide range of narrative strategies and artistic techniques which contest and deconstruct the accepted established cultural forms of transmission of the Holocaust memory. The three analyzed examples are Polish author Igor Ostachowicz's Noc żywych Żydów (Night of the Living Jews [2012]), Polish author Mariusz Sieniewicz's Żydówek nie obsługujemy (We Don't Serve Jewesses [2006]), and German author Maxim Biller's In Kopf von Bruno Schulz (Inside the Head of Bruno Schulz [2013; translated 2015]).

Authors: Al Manir Mohammad Sadnan , Spencer Bruce , Baker Christopher J.O.
Published: June 2018

Informational needs of agricultural consultants are increasingly complex. Advising farmers on the appropriate measures for optimizing cropping yields demands access to custom data archives and analytics tools. In line with the increasing number of archives, the expertise required of consultants goes beyond the capabilities of these non-technical agri-specialists. These end users have diverse ad-hoc query needs and require tools that provide simple access to distributed data silos and easy ways to integrate relevant information. In this article, the authors report on a pilot deployment of Semantic Automated Discovery and Integration (SADI) Web services for the federation and computation of agricultural data. A registry of 9 SADI Web services was deployed to expose data from a variety of different data resources in support of a defined set of query needs. The authors demonstrate that the deployment of these services facilitates the ad-hoc creation and execution of mission critical workflows targeting use cases in agricultural operations management. Using HYDRA, a semantic query engine for SADI Web services with a custom built graphical user interface, agricultural consultants can identify optimal crop varieties, and compute profit margins of each variety using a complex cost model.

Published: June 2018

Background: The South African Department of Health implemented the nurse-initiated management of antiretroviral treatment (NIM-ART) programme as a policy to decentralise services. Increasing access to ART through nurse initiation results in significant consequences.Aim: This study evaluated the quality of care provided, the barriers to the effective rollout of antiretroviral services and the role of a clinical mentor.Setting: The study was conducted at three NIM-ART facilities in South Africa. One clinic provided a high standard of care, one had a high defaulter rate, and at the third clinic, treatment failures were missed, and routine bloods were not collected.Methods: A mixed methods study design was used. Data were collected using patient satisfaction surveys, review of clinical records, facility audits, focus group interviews, field notes and a reflection diary.Results: NIM-ART nurses prescribed rationally and followed antiretroviral guidelines.Mortality rates and loss to follow-up rates were lower than those at the surrounding hospitals, and 91.1% of nurse-monitored patients had an undetectable viral load after a year. The quality of care provided was comparable to doctor-monitored care. The facility audits found recurrent shortages of essential drugs. Patients indicated a high level of satisfaction. Salary challenges,excessive workload, a lack of trained nurses and infrastructural barriers were identified as barriers. On-going mentoring and support by a clinical mentor strengthened each of the facilities, facilitated quality improvement and stimulated health workers to address constraints.Conclusion: Clinical mentors are the key to addressing institutional treatment barriers and ensuring quality of patient care.

Authors: Moses J.E. , Jennitta I. , Jims John Wessley G.
Published: June 2018

Loss of lives due to fatal air accidents is an alarming problem faced by the aviation industry. There have been 88 fatal air accidents in the years 2010-2014 according to the IATA safety report. This clearly exhibits the fact that the present safety systems in aircraft are inadequate to save lives during mid-air emergencies. This paper presents a feasible solution to this problem with the use of controllable aircraft rescue system CARS involving the use of parachutes and parafoils. Parachutes are placed at the center, nose and tail sections of the aircraft which when deployed during a mid-air emergency to decrease the sink rate, provides stability and much-needed lift to the aircraft. Parafoils are attached to the wings of the aircraft through the fuselage which when deployed provides the much-needed control and enables safe navigation of the aircraft. Floats are provided at the bottom of the fuselage to reduce the force at impact in case of touchdown and also increase the time for which the aircraft can stay afloat in case of water landing. An analysis is performed to determine the size and diameter of parachutes required for aircraft of varying weights. The time of descent of the aircraft with parachutes from various altitudes is also determined. These results are summarized to exhibit the feasibility of the system.

Authors: Ramakrishna M. , Syedhaleem M. , Divya C. , Gurunathan A.
Published: June 2018

The need to determine forces and moments acting on bodies of revolution at high angles of attack originally arose in connection with airships. In general missile aerodynamics is dominated with vertical and separated flows. The advent of highly manoeuvrable missile design concepts has required a major effort in understanding the problem of slender bodies of revolution at high angles of attack. An extensive experimental investigation was conducted to determine the aerodynamic forces and moments. The aerodynamic data are needed to establish the structural and control system requirements. Tests were conducted on a smooth missile model with several interchangeable nose parts in a wind tunnel at subsonic level at high angle of attack. The yaw moments and side forces are determined using force measuring systems by which maximum induced side force was found. Using oil flow visualization technique, vortex shedding location and vortex strength were traced at various angles of attack. Computational analysis was carried out for the cone, elliptical and ogive nose shapes. It is then compared with the experimental results to know where the least ï¬‚ow separation occurs and proper reasons for the side forces.

Published: June 2018

This paper details the influence of geometry variation such as shape transition of the isolator from its entry to exit on overall performance of scramjet isolators. The experiments are conducted to assess the performance of two isolator geometries of circle to pentagon and circle to hexagon. The pseudo shock length is obtained for the two cases by observing the sudden pressure rise in pressure plots taken along the wall. It is found that the shock train length is shorter for circular to pentagon duct compared with the other duct. Hence, this duct is preferable in order to prevent inlet non-start induced by the pressure rise in the combustion chamber.

Published: June 2018

Radars demand low profile and light weight antenna subsystems. Microstrip antennas possess these characteristics and serve as an alternative to the bulky and heavy weight reflector/slotted waveguide array antennas, thus an ideal choice for radars. Here, a single line fed microstrip antenna with pierced corners is designed. This antenna has improved parameters compared to the conventional square microstrip antenna. The main problem encountered is in designing the patch antenna with optimum values for various antenna parameters. In order to solve this problem, an alternative solution used is Artificial Neural Networks (ANN). The antenna is also optimized using Particle Swarm Optimization (PSO). The parameters considered in all the cases are return loss (S11) and VSWR which was designed using FEKO software. The designed antennas are found to radiate in the C-band, which covers frequencies in the range 5-8GHz, applicable in most of the modern radars. The simulation design is carried out using CADFEKO suite.

Magnetorheological (MR) fluid damper has been designed, fabricated and tested to find the stiffness and damping characteristics. Experimentally the MR damper has been tested to analyse the behaviour of MR fluid as well as to obtain the stiffness for varying magnetic field. MR damper mathematical model has been developed for evaluating dynamic response for experimentally obtained parameters. The experimental results show that the increase of applied electric current in the MR damper, the damping force will increase remarkably up to the saturation value of current. The numerical simulation results that stiffness of the MR damper can be varied with the current value and increase the damping forces with the reduced amplitude of excitation. Experimental and theoretical results of the MR damper characteristics demonstrate that the developed MR damper can be used for vibration isolation and suppression.

Published: June 2018

From 1940s to till now the Un-manned aerial vehicles (UAVs) technology has been developed and the birds like UAVs are actively used for spying mission to attack enemies. For example, â€œSmart Birdâ€ is discovered by FESTO in which the seagull is taken as a concept. The battery consumption is more on these UAVs due to their complicated flapping mechanism. This project deals with an UAV (ornithopter) with morphed wing, in which the wing can be foldable to increase the gliding speed. By using such type of wings, endurance and range can be increased. A laboratory scale ornithopter with flapping wing mechanism is fabricated and tested. The flight speed of almost 45mph can be achieved. This mechanism reduces the battery consumption, for e.g. for 8V input, 4 flaps per second is demonstrated by test. UAV has the ability to attack enemy territory without being identified by the RADAR. Moreover, it can be used to drop bombs from high altitude with precision by using high resolution cameras. To overcome this difficulty, the ornithopter with morphing and flapping mechanism concept is considered in this project.

Published: June 2018

The problem of resonance in a geocentric synchronous satellite under the gravitational forces of the Sun and the Earth subject to Poynting-Robertson (P-R) drag is the subject matter of this paper. Based on the assumption that the two bodies the Earth and the Sun lie in ecliptic plane and the satellite in the orbital plane. Five resonance points results from commensurability between the mean motion of the satellite and the average angular velocity of the Earth. Out of all resonance, the 3:2 and 1:2 resonance occurs only due to velocity dependent terms of P-R drag. We have determined the amplitude and time period of the oscillation in two different cases at those resonance points.

Modeling and Simulation of Off-Road Vehicle Mobility with Driving Torque Distribution Control on Split Adhesion Conditions
Authors: Abd El-Hafiz M.M. , Emam M.A.A , Oraby W.A.H , Shaaban S.
Published: June 2018

This paper presents a theoretical model for simulation of driving torque distribution control to improve off-road vehicle mobility on split adhesion conditions. The model is constructed and then validated with experimental test rig results. A MATLAB simulink modeling of an electronically controlled device is used to modulate the applied force over multi-plate clutches located between the automotive driven axle shafts and the stationary hub. On driving over split adhesion roads, the control device brakes the spinning axle wheel running over ground low adhesion side and accordingly biases more torque to the other wheel with good adhesion side. This would improve the vehicle off-road mobility and save the power losses on low adhesion wheels. The proposed control model had been validated with experimental results obtained from an experimental tests conducted on a specially designed and built test rig. Consequently, the proposed control system has been embedded within a full car theoretical model to predict the vehicle performance on split adhesion drive conditions. The results showed that the constructed simulink model is suitable for simulating the proposed controlled device for torque distribution after matching the simulation results with experimental test rig results. Moreover, the proposed control model could be implemented to improve the transmitted traction power to the road from a conventional deferential.

Compression ignition engines are widely used due to their lower energy consumption and enhanced combustion efficiency. In this experimental investigation, the feasibility of fuelling a single cylinder 4 stroke direct injection compression ignition engine with methyl esters of palmkernel (PME) oil along with various fractions of aluminium oxide nano particles (ANOP) were analysed. Two stage transesterification process was adopted to prepare PME. PME20 blend was formulated and fused using high speed homogenizer with varying proportions of AONP as 25 ppm, 50 ppm and 100 ppm in the presence of hexadecyl trimethyl ammonium bromide as surfactant. The experimental investigations were conducted at rated power of 3.5kW at 1500rpm. It was noticed that supplementation of AONP affected the ignition delay significantly favouring enhanced combustion efficiency. The rate of heat release and in-cylinder pressure was substantially increased with notable reduction in ignition delay. Addition of AONP showed an increase in brake thermal efficiency and exhaust gas temperature with diminution in brake specific energy consumption. The unburned hydrocarbons, carbon monoxide and smoke density decreased sharply with an upsurge in NOx. Increase in AONP concentration up-to 100 ppm with PME20 was found to give better combustion and performance characteristics.

To investigate the effect of active roll stabilizer system performance on vehicle stability, it is needed to study the effects of varying speeds of the on-road vehicles under different wheel steer angle on the roll angle, side slip angle and yaw rate on the vehicle stability. For a safe drive, when a vehicle is cornering it should not lose its stability on road. In this paper the response of passive and active roll stabilizer vehicle systems are simulated and compared against each other. The results of the simulation model showed a significant influence of the vehicle speed on the vehicle stability under different wheel steer angles.

Presently arc welded structures are extensively used in automobiles, constructions and power plants. As the main cause of weldment failure is design defect and overload, it is necessary to analyze the maximum stresses in the weldment. This work deals with investigation of welded T-joint by Tungsten Inert Gas (TIG) welding process with varying gap and angle between the parent materials to determine the breaking stress under tensile load in the weldment. Finite element analysis is carried out using Ansys software and results are compared with experimental analysis using Taguchi optimization method. Angle, arc force and gap between parent materials are used for the Taguchi optimization technique. The optimized fillet weld section (low carbon steel AISI1020 and copper) is arrived by restricting the weldment failure.

Vehicle vibration can be controlled by Active Suspension System (ASS). The performances of ASS are better than the conventional Passive Suspension System (PSS). The effectiveness of ASS is based on the type of controllers used. In this paper, a quarter car model with ASS is considered for analysis. To reduce the vibration and improve the ride quality, Fractional order Fuzzy Sliding Mode Controller (FrFSMC) is proposed and its performances are compared with Fuzzy Sliding Mode Controller (FSMC) and passive system. While testing the performance of the controllers three types of road disturbances are given to the quarter car model to stimulate the vibration. The results of the proposed controllers are also compared against the existing Gray Fuzzy Sliding Mode Controller (GFSMC). From the time responses and root mean square indices, FrFSMC performs better than the FSMC, GFSMC and PSS.

Internal combustion engines generate undesirable emissions during the combustion process. The NOX, HC, CO2 and CO emissions exhausted into the surroundings pollute the atmosphere that leads harming the human beings. The major causes of the emissions of pollutants are non-stoichiometric combustion, oxidation and reduction of nitrogen and impurities in the fuel and air. Thermal or catalytic converters and particulate traps are used for the post-treatment of exhaust gases [5]. In this investigation, an attempt has been made to control the engine exhaust emissions by using metal-oxide coated filters. The coating is performed by using vacuum coating unit over the surface of the mesh. The results obtained from the experiments using the filter coated with copper oxide, magnesium oxide, ferric oxide, cobalt oxide, copper oxide and their combinations were analyzed. The emission control achieved by adopting this technique was found to be effective.

Trackless vehicles have been widely used for the underground mining in many coal-rich countries. However, their vibration is violent and this vibration could affect the driver's health and reduce the working efficiency. Therefore, how to solve this question about the vibration and shock has become an urgent and important thing. In this paper, a type of tubular constrained damping engine mount is designed and first used in the underground trackless vehicles. This tubular damping structure is made of three layers, the external and internal layer are made of steel and the middle layer of natural rubber is sandwiched between them. To know about the vibration-reducing performance of the new designed mounts, the real vehicle test was performed under two working conditions. The results show that the two rear mounts could obtain good vibration isolation effect, whereas the performance are sometimes poor in a certain direction for the two front mounts because of the vibration energy coupling in different directions. Further research is to optimize the parameters of the tubular constrained damping engine mount to make the vibration energies from different directions decoupled.

In this work, experimental investigation was carried out to test the performance and emission characteristics of a CI engine using diesel and cotton seed oil methyl ester blended fuel (COSME20) along with titanium oxide nano particles as an additive in biodiesel blends. The titanium oxide nanoparticles promote the combustion process that results in more oxidation of CO and reduces HC emission. The engine test was conducted with various blends of diesel and biodiesel with and without nanoparticles, namely B20 (20% biodiesel + 80% diesel), BN20 (20% biodiesel + 80% diesel + 20ppm), BN40 (20% biodiesel + 80% diesel + 40ppm) at different loads. The test results showed that the addition of titanium oxide nanoparticles in diesel and biodiesel blends improved combustion and reduced the exhaust gas emissions significantly.

Published: June 2018

This paper focused to determine optimal bonding parameters based on Taguchi method for maximizing bonding strength. The experiments were conducted on diffusion bonding machine using aluminium fly ash (AFA) composites. Three bonding parameters such as temperature, pressure and time, each at three levels were examined. Taguchi L27 orthogonal array was used as a design of experiment. The response table and the analysis of variance (ANOVA) were calculated to determine which process parameters significantly affect the bonding strength and also the % contribution of each parameter. The results show that the combination of factors and their levels of A2B3C3 i.e. the bonding done at a temperature of 475Â°C with a pressure of 10 MPa and time for 20 minutes yielded the optimum i.e. maximum bonding strength. Finally, ANOVA results indicated that all three process parameters significantly affected the bonding strength with a maximum contribution from the bonding temperature (85.93%), followed by bonding time (12.6%) and bonding pressure (1.48%). It is also observed that the bonding strength of the diffusion bonding process can be improved effectively through this approach.
