  R.Jogarao, Mouliswararao.Reddy, G.Ashok
  [Abstract] [PDF] [Cite]

Abstract:

Brushless DC Motors (BLDCM) are widely used in automated industrial applications like Computer Numerical Control (CNC) machinery, aerospace applications and in the field of robotics.But it still suffers from commutation torque which mainly depends on speed and transient line commutation interval. BLDC MOTOR torque ripple causes increased acoustic noise and undesirable speed fluctuation. This paper presents a new circuit topology and dc link voltage current in the control strategy to keep incoming and outgoing phase currents changing at the same rate during commutation. In this paper dc-dc single ended primary inductor converter (SEPIC) a switch selection circuit are employed in front of inverter. In order to obtain the desired commutation voltage resulting in reduced commutation torque ripple. Compared with simulation result conventional system and proposed method can obtain desired voltage much faster and minimize commutation torque ripple more efficiently.
Key words:Brushless DC Motor(BLDCM),DC link voltage, Commutation, Single ended primary inductor converter(SEPIC).

  [Abstract] [PDF] [Cite]

Abstract:

This research presents a detailed account of map generating, comprehensive coverage, path plotting and scheming, as well as control mechanism for a mobile automation robot comprising of the automated ground cleaning of average to small indoor areas as an application objective. The algorithms put forward are centered upon supervised 2D map of the surrounding which is generated during the training phase and have the capacity to deal successfully with unforeseen obstacles which were not determined on the 2D map. The map is generated using dead reckoning algorithm and then an approach relying on templates is used for controlling execution of the path plan. The capability of the robot to deal with generation of the map, detecting unforeseen obstructions inside the work space and localizing itself in the map is the suggested approach's originality. If unmapped obstructions continually block the planned path, the trajectory tracing control inserts these obstacles in the 2D map..

Abstract:

In today's scenario threat of enemies and terrorist attack is increasing. Therefore consideration of blast load in analysis and design is essential. A bomb explosion within or nearby outside the building can cause catastrophic failure of building. Blast loads have, in the recent past, become important service loads for certain categories of structure. An important task in blast resistance design is to make a realistic prediction of blast pressure. The distance of explosion from the structure is an important datum, governing the magnitude and duration of blast loads. In the present study, the RCC frame was analyzed by using conventional code for gravity loads using moment resisting frame. The blast load was calculated using UFC-340-02 (2008) or IS 4991-1968 for 500 kg and 100 Kg TNT at standoff distance of 10m and 30m from face of column at first floor level. The triangular impulse was applied as nodal time history at all front face joints........

  [Abstract] [PDF] [Cite]

Abstract:

The energy performance of buildings is defined by their electrical systems and thermal exchanges through the envelope, mainly by glazing systems. This study evaluates, through computer simulation, the influence of glazing façades in the energy consumption of the air conditioning system of an office building in five Brazilian cities with different climate conditions. A computer model was developed to analyze the influence of window-to-wall ratio, type of glass and façade configuration in the energy need for air conditioning. The results show that the energy performance of the building is highly influenced by the configurations of the façade, mainly by glazed elements. In cold climates, high thermal transmittance of the envelope helps the dissipation of internal heat gains, reducing energy consumption for air conditioning.......

Abstract:

The mechanical design and of a square hole producing tool based on Reuleaux Triangle. The main aim of our papaer is to investigate how the circular motion can be converted into a square motion by purely a mechanical linkages; an application of which is to construct a special tool that drills exact square holes. The geometrical construction that fulfils the laid objective is Reuleaux Triangle . Additionally, for this geometry to work like a rotating drive (such as a drill press) must force the Reuleaux triangle to rotate inside a square, and that requires a square guide to constrain the Reuleaux triangle as well as a special coupling to describe the fact that the center of rotation also in moves within in the constrain. The practical importance of this enhancement is that the driving end can be placed in a standard drill press; the other end is restricted to stay inside the fixed square, will yield a perfectly square locus and this can be turned into a working square-to drill hole.

Abstract:

The main objective of this paper is to control the speed of an induction motor by using seven level diode clamped multilevel inverter and improve the high quality sinusoidal output voltage with reduced harmonics. The presented scheme for diode clamped multilevel inverter is sine carrier Pulse Width Modulation control. An open loop speed control can be achieved by using V/ƒ method. This method can be implemented by changing the supply voltage and frequency applied to the three phase induction motor at constant ratio. The presented system is an effective replacement for the conventional method which has high switching losses, its result ends in a poor drive performance. The simulation result portrays the effective control in the motor speed and an enhanced drive performance through reduction in total harmonic distortion (THD). The effectiveness of the system is verified through simulation using PSIM6.1 Simulink package..

Abstract:

Hygiene practices have effects on vulvovaginal microbiota. Specific products for intimate female hygiene are available in the market, such as the sanitary pads. Since these pads were introduced in the market , they became the focus of research that seek to improve their shape, manufacturing processes and the properties of materials used in order to provide more benefits to users. Thus, the present study aimed to characterize the fabrics used in daily sanitary pads, focusing on the development of future products. The spectra generated by FTIR/ATR suggest that the samples were composed of polypropylene. The photomicrographs showed that the polymeric outer layer was made of nonwoven fabric manufactured by spunbond and point bonding processes..

  [Abstract] [PDF] [Cite]

Abstract:

The surface soil moisture content (SSMC) is of great importance to the discipline of hydrology as well as to the other relevant studies and applications. Pioneer studies have pointed out that the most promising technique to retrieve SSMC regarding to accuracy and cost-effective belongs to the micro-wave remote sensing. By means of field observed SSMC dataset collected from the Yihe watershed located on the Linyi district, Shangdong province, China, we analyzed and validated the daily AMER-E SSMC products for the year of 2006 with the focus to examine the products quality of AMER-E SSMC for further studies by using the products. The results suggested that the temporal variation trend of AMER-E remotely sensed SSMC is reasonably consistent to the field observed, but is systematic lower than the ground truth in value in the whole year. The correspondence of AMSR-E SSMC product is significant enough compared with the field observed for the whole year except of the month of July and August.

• Comparative Analysis for NN-Based Adaptive Back-stepping Controller and Back-stepping Controller
  Margarita Gjonaj, BetimÇiço, ArnisaMyrtellari
  [Abstract] [PDF] [Cite]

Abstract:

This work primarily addresses the design and implementation of a neural network based controller for the trajectory tracking of a differential drive mobile robot. The proposed control algorithm is an NN-based adaptive controller which tunes the gains of the back-stepping controller online according to the robot reference trajectory and its initial posture. In this method, a neural network is needed to learn the characteristics of the plant dynamics and make use of it to determine the future inputs that will minimize error performance index so as to compensate the back-stepping controller gains. The advantages and disadvantages of theproposed control algorithms will be discussed in each section with illustrations.Comprehensive system modeling including robot kinematics and dynamics modeling has been done. The dynamic modeling is done using Newtonian and Lagrangian methodologies for nonholonomic systems and the results are compared to verify the accuracy of each method. Simulation of the robot model and different controllers has been done using Matlab and Matlab Simulink..

• Analysis of the Dynamic Behaviour of Steel-Concrete Composite Footbridges Considering the Soil-Structure Interaction
  J.G. Santos da Silva, A.C.C. Fontenla Sieira, G.L. Debona
  [Abstract] [PDF] [Cite]

Abstract:

The main objective of this investigation is to present the finite element modelling of the dynamic behaviour of a steel-concrete composite footbridge, when subjected to human walking vibrations. The investigated structural system was based on a tubular steel-concrete composite footbridge, spanning 82.5 m. The structural model consists of tubular steel sections and a concrete slab. This investigation is carried out based on correlations between the experimental results related to the footbridge dynamic response and those obtained with finite element modelling. The soil-structure interaction effect was considered in the dynamic analysis based on the use of Winkler's theory. The finite element model enabled a complete dynamic evaluation of the tubular footbridge in terms of human comfort and its associated vibration serviceability limit states. The peak accelerations found in this analysis indicated that the investigated footbridge presented problems related with human comfort and it was detected that the structural system can reach vibration levels that compromise the footbridge user's comfort

Abstract:

The wealth of tiles in Portugal is made of more than the early patterned and the blue on white pictorial panels that cover the interior walls of churches, monasteries and palaces throughout the country and its former possessions. In the first half of the 19th century azulejo workshops found a new market in the owners of recent urban constructions, producing facade tiles widely used subsequently not only in many Portuguese towns but also in Brazil, to where they were exported in large numbers. The new urban look was not unanimously liked at its heyday but as time goes by, the old streets with shiny and often lively coloured facade walls are slowly gaining their place in the lists of municipal heritage worth preserving.........

Abstract:

In the present paper a numerical attempt is made to study the combined effects of heat source and sink on unsteady laminar boundary layer flow of a viscous, incompressible, electrically conducting fluid along a semi-infinite vertical plate. A magnetic field of uniform strength is applied normal to the flow. The governing boundary layer equations are solved numerically, using Crank-Nicolson method. Graphical results of velocity and temperature fields, tabular values of Skin-friction and Nusselt are presented and discussed at various parametric conditions. From this study, it is found that the velocity and temperature of the fluid increase in the presence of heat source but they decrease in the presence of heat absorption parameter..

• Integrity Privacy to Public Auditing for Shared Data in Cloud Computing
  A.Mahaboob Basha, P. Venkata Maheswara
  [Abstract] [PDF] [Cite]

Abstract:

In cloud computing, many mechanisms have been proposed to allow not only a data owner itself but also a public verifier to efficiently perform integrity checking without downloading the entire data from the cloud, which is referred to as public auditing . In these mechanisms, data is divided into many small blocks, where each block is independently signed by the owner; and a random combination of all the blocks instead of the whole data is retrieved during integrity checking .However, public auditing for such shared data— while preserving identity privacy — remains to be an open challenge. Here, we only consider how to audit the integrity of shared data in the cloud with static groups. It means the group is pre-defined before shared data is created in the cloud and the membership of users in the group is not changed during data sharing..............

• A Review on Power System Voltage Stability and Optimization Techniques
  T. Madhuranthaka, Dr.T.Gowri Manohar
  [Abstract] [PDF] [Cite]

Abstract:

Power system voltage stability is a one of the major focused areas in recent days due to mismatch between generation and demand. Maintenance of voltage stability is a challenging issue in planning and security assessment of power systems. Voltage stability is the ability of a power system to maintain steady acceptable voltages at all buses in the power system under normal operating conditions and after being subjected to a disturbance. Long-term voltage instability problems can occur in heavily loaded systems where the electrical distance is large between the generator and the load. Timely application of reactive power compensation or load shedding may prevent this type of voltage instability

Abstract:

The mechanism of soil-geosynthetic interaction is usually complex and depends on the nature of the reinforcement, as well as on the characteristics of the surrounding soil. The strength parameters of the interface are the key for the design of reinforced soil slopes. Usually, these parameters are defined from laboratory pullout tests. The absence of test results implies on conservative assumptions and higher costs. The possibility of using computer programs for analyzing the load transfer mechanism arises as an attractive design tool. This paper presents the numerical simulation of pullout tests, conducted in large equipments.........

• Performance Analysis of Copper Twisted Tape Inserts for Heat Transfer in A Circular Tube
  Mukesh P. Mangtani, Prof K.M. Watt
  [Abstract] [PDF] [Cite]

Abstract:

Thermal Performance of heat transfer devices can be improved by heat transfer enhancement techniques. In the present study, heat transfer from hot air to cold water by double pipe heat exchanger for plain tube and plain tube with twisted inserts is experimentally investigated at isothermal condition. The twisted tape inserts when placed in the path of the flow of the fluid, create a high degree of turbulence resulting in an increase in the heat transfer rate. By inserting twisted tape with twist ratio y=5 and y=7 in a concentric tube heat exchanger, the Nusselt number increases gradually from 920 to 6700 and it is 12-15 % higher than plain tube. This is due to the generation of secondary flow in the tube (turbulence flow). Also the heat transfer coefficient is 15 % higher than the plain tube due to increase in degree of swirl

Currently in Brazil, the deposition technique of bauxite residues provides an initial operation to discharge waste within artificial lakes, in a slurry form (wet disposal). After achieving the storage capacity of the reservoir and drying the waste, the embankment is raised by the upstream method. So, the slurry is discharged on top of a material which is undergoing a consolidation process. The prediction of bauxite wastes behavior is a challenge for geotechnical engineers, since these materials show a distinct response of the materials usually found in natural deposits.........

• Optimal Congestion Management in an Electricity Market Using Versatile Particle Swarm Algorithm

  [Abstract] [PDF] [Cite]

Abstract:

Transmission lines in power system network operate close or beyond their thermal limits are said to be congested. In deregulated electricity markets the problem is more likely to occur due to unplanned power exchanges. Congestion management (CM) is accomplished mainly either by generator rescheduling or by load shedding. In load shedding reliability of power supply gets affected so re-dispatching the output of generator is better option to manage congestion while ensuring the system reliability. In generator rescheduling or re-dispatching independent system operators reschedule the generator output so that congestion has gotten rid off. In this operation independent system operator (ISO) commands the generator of low-price area to lower down its output while purchasing power from high price areas this will lead to an additional cost known as rescheduling cost..........

A novel fuzzy based Excitation Failure detection scheme for alternators is being attempted in this work. This work uses voltage-impedance trajectory and reactive power to clearly identify Excitation Failure from Stable Power Swing. For making a decision between Excitation Failure and Stable Power Swing the parametric values are not considered as actual (crisp) but taken as a fuzzy set. The attempted work in this paper results in a safe and reliable fast mechanism which clearly indentifies Excitation Failure and Stable Power Swing without misinterpretation.

• Dynamic Analysis and Human Comfort Evaluation of Soccer Stadium Grandstands
  D.F. Campista, J.G. Santos da Silva, A.C.C. Fontenla Sieira, R.B. Burgos
  [Abstract] [PDF] [Cite]

Abstract:

Over the years, many soccer stadiums in Brazil have been designed to withstand accidental loads (people loads) to be of static type. However, based on the changes in the people's behaviour, especially in soccer matches, through the action of groups of fans and also with the use of these structures for rock concerts, these structural systems have been subjected to dynamic impacts related to the dynamic nature of the applied loads. Therefore, some of these stadiums in Brazil have presented excessive vibration problems and have required an effective consideration of the dynamic loadings in the structural design..........

• Vibration Analysis and Human Comfort Evaluation of Steel-Concrete Composite Footbridges Based on the Modelling of the Pedestrian-Structure Dynamic Interaction Effect
  J.G. Santos da Silva, R.B. Burgos, I.F.B. Duarte, G.L. Debona
  [Abstract] [PDF] [Cite]

Abstract:

This work aims the development of an analysis methodology to investigate the dynamic behaviour of steel-concrete composite footbridges. The composite footbridge dynamic response is analysed based on two different strategies. Firstly, the traditional simulation of human walking, without consideration of the pedestrian-footbridge dynamic interaction effect is considered. On the other hand, the effect of the dynamics of the pedestrians while crossing footbridges in crowd situations is analysed and the pedestrian-footbridge dynamic interaction, based on the use of biodynamic models is investigated using a second strategy..........

• The Haar-Recursive Transform and Its Consequence to the Walsh-Paley Spectrum and the Autocorrelation Function
  H. M. Rafiq, M. U. Siddiqi
  [Abstract] [PDF] [Cite]

Abstract:

The Walsh and Haar spectral transforms play a crucial part in the analysis, design, and testing of digital devices. They are most suitable for analysis and synthesis of switching or Boolean functions (BFs). It is well known that, the connection between the two spectral domains is given in terms of the Walsh-Paley transform. This paper derives an alternative expression of the Walsh-Paley transform in terms of the Haar transform. The work demonstrates the possibility of obtaining both the Haar spectrum and the Walsh-Paley spectrum using only the Haar transform domain..........

• Evaluation of the Sensitivity of Seismic Inversion Algorithms to Different Statistically Estimated Wavelets
  V. M. Gomes, M. A. C. Santos, R. B. Burgos, D. M. S. Filho
  [Abstract] [PDF] [Cite]

Abstract:

Seismic wavelet estimation is an important step in processing and analysis of seismic data. Inversion methods as Narrow-Band and theConstrained Sparse-Spike ones require information about it so that the inversion solution, once it is not a unique problem, may be restricted by comparing the real seismic trace with the synthetic generated by convolution of the estimated reflectivity and wavelet. Besides helping in seismic inversion, a good estimate of the wavelet enables an inverse filter with less uncertainty to be computed in the deconvolution step and while tying well logs, a better correlation between the seismic trace and well log can be achieved. Depending on the use or not of well log information, the methods of wavelet estimation can be divided into two classes: statistical and deterministic. This work aimed to test the sensitivity of acoustic post-stack seismic inversion algorithms to wavelets statistically estimated by two distinct methods.

• Heavy Metals Assessment in Water Reservoirs Reinforced By Służewiecki Stream
  Małgorzata Wojtkowska, Ewa Karwowska, Iwona Chmielewska, Krzysztof Wawer
  [Abstract] [PDF] [Cite]

Abstract:

The study concerned copper and cadmium contamination in bottom sediments of selected surface water reservoirs at the urban area. The concentrations of the metals in sediments was up to 20-times higher compared with a geochemical background. Based on ecotoxicological evaluations, the toxic impact of cadmium in tested sediments can occur frequently, while for copper – it can sometimes be observed. The sediments can be classified as heavily polluted and dangerous to water biota, especially for sediment-dwelling organisms. The accumulation of metals migrating with the Służewiecki stream in reinforced reservoirs can result in their anthropopressure- related degradation..

Abstract:

Labor absenteeism has been identified as one of the main factors delaying construction projects. This paper reports an approach to quantitatively estimate the effect of labor absenteeism on the duration of construction activities in housing projects, using discrete event simulation. Absenteeism and productivity data from fourteen housing projects were used to estimate the effect of absenteeism on four construction activities from three different projects. Moreover, four different absenteeism scenarios were analyzed with this methodology: no absences of skilled or unskilled workers; with absences of unskilled workers only; with absences of skilled workers only; and with absences of both skilled and unskilled workers at the same time.........

• Optimization to Mitigate Voltage Harmonics of Cascaded Multilevel Converters
  Arabinda Mishra, Debasis Mishra, Srinibas Swain, Rajesh Kanungo
  [Abstract] [PDF] [Cite]

Abstract:

The use of pulse width modulation with selective harmonic elimination (SHE-PWM) in cascaded H-bridges (CHB) multilevel converters allows the reduction of the output current distortion by the elimination of low order harmonic components. However, voltages produced by CHB modules to synthesize the SHE-PWM pattern is an issue that deserves deeper investigation. CHB systems fed by sources with current source characteristics, as photovoltaic strings operating with MPPT, may feature dif- ferent source capacities. Thus, it is important that the energy provided by each module is proportional to the available energy, so input voltages remain balanced. This paper presents the development of a genetic algorithm (GA) to determine optimal waveforms to be synthesized by the CHB modules that ensures the equalization of the fundamental components, or even that a specific relationship between between them is achieved. Simula- tion results for five and nine-levels demonstrate the applicability of the technique, allowing the voltage balance of the DC buses tobeaddressedeveninthemodulationstage..
