  • Step Response and Estimation of Lateral and Yaw Motion Disturbance of Rail
           Wheel set

    • Authors: Zulfiqar Ali Soomro
      Pages: 8 - 13
      Abstract: Zulfiqar Ali Soomro
      Journal of Engineering and Technology 2015 5(1):8-13
      The rail wheelset dynamics has skeleton importance to avoid the slip and slide due to insufficient adhesion level depending on creep forces. Proper study and control upon lateral and yaw motion owing to creep forces may reduce the problem at some extent. In this paper, this dynamics of wheelset with its possible degree of freedom has been discussed and limited to lateral and yaw analysis. These analyses have been computed and simulated by simulink to observe their behavior. The disturbances of these dynamical parameters are estimated using Kalman filter. The correlation of actual and estimated curves has been assessed to invent novel idea.

  • A Paradigm to Produce Customized Ankle Support Using Incremental Sheet
           Forming

    • Authors: Vishal Gulati, Sumit Kathuria, Puneet Katyal
      Pages: 14 - 18
      Abstract: Vishal Gulati, Sumit Kathuria, Puneet Katyal
      Journal of Engineering and Technology 2015 5(1):14-18
      This paper presents a paradigm to produce customized ankle support through the use of reverse engineering (RE) process, which uses the patient's scan data to an optimal form using a computer-aided design (CAD) system and then transferring the three-dimensional CAD model to Incremental Sheet Forming (ISF) technique for the production of tangible prosthesis product. This work is in the direction of forming of such a customized ankle support that minimizes the gap between the implanting prosthesis and the ankle. Such type of products may be prefabricated or customized. Prefabricated products are manufactured according to the standard sizes of different persons and customized are fitted after observing the patient's computed tomography scan. Prefabricated products do not guaranteed that the product will fit or not to the geometry of patient. On the other side, customized products provide more comfort and satisfaction than prefabricated products. RE design process has been implemented in order to acquire CAD model from the patient's scan data and to use this information for computer controlled layered manufacturing technique like ISF.

  • Stochastic Dynamic Job Shop Scheduling with Sequence-Dependent Setup
           Times: Simulation Experimentation

    • Authors: Pankaj Sharma, Ajai Jain
      Pages: 19 - 25
      Abstract: Pankaj Sharma, Ajai Jain
      Journal of Engineering and Technology 2015 5(1):19-25
      Stochastic dynamic job shop (SDJS) scheduling problems with sequence-dependent setup times are among the most difficult classes of scheduling problems. This paper assesses the performance of five dispatching rules (DRLs) in such shop from makespan, mean flow time, mean tardiness, number of tardy jobs, total setups, and mean setup time performance measures viewpoint. A discrete event simulation model of a SDJS manufacturing system is developed for investigation purpose. Five DRLs, that is, first come first serve (FCFS), shortest processing time (SPT), shortest setup time (SIMSET), earliest due date (EDD) and shortest sum of setup times and processing time (SSPT) are incorporated in the simulation model. The simulation experiments are conducted under due date tightness factor of 3, shop utilization percentage of 90 and setup time less than processing time. Results indicate that SIMSET rule provides best performance for mean flow time and number of tardy jobs performance measures. The SPT rule provides best performance for mean tardiness measure. The EDD rule is best-performing DRL for makespan, total setups and mean setup time measures.

  • Multi-Agent Based Cloud Service Composition using Contract Net Protocol
           for Information Retrieval Purpose

    • Authors: Yu Mon Zaw
      Pages: 26 - 30
      Abstract: Yu Mon Zaw
      Journal of Engineering and Technology 2015 5(1):26-30
      Information retrieval (IR) systems are important key players for every Internet user and there are many Information Retrieving frameworks and algorithms, which are currently using or under development. As the technology trend is always changing and current industrial and business world is willing to emphasize on not only providing knowledge but also supporting service, cloud computing and Web Services (WSs) become popular. Cloud computing is internet based system development in which large scalable computing resources are provided "as a service" over the internet to users and has attracted more and more attention from industry and research community. WS plays important role in service oriented computing in World-Wide-Web and Cloud environment. Developing a Cloud Wide IRSystem using WSs can fill one blank of Cloud Environment. In this case, retrieving desired specific information from WSs on Cloud Environment cannot be completed by single WS. Hence, there should be a way to build an IRSystem based on a set of related WSs in order to fulfill users' requests and provide desired services. To compose WSs, Multi-Agent System (MAS) can give great help. Agent systems are self-contained software programs embodying domain knowledge and having ability to act as a specific degree of independence to carry out actions needed to accomplish desired goals. Therefore, this paper mainly focuses on building a WSs Based IR MAS framework and Agent Processing Algorithm, which will be running on a Private Cloud Environment. We propose Contract Net Protocol for IR Purpose in order to perform WSs Composition. The implementation and testing of this system utilizes the real datasets of clinics in the Yangon area.

  • Groundwater Simulation Model for Sirhind Canal Tract of Punjab

    • Authors: Pamela Miglani, Rajan Aggarwal, Samanpreet Kaur
      Pages: 31 - 35
      Abstract: Pamela Miglani, Rajan Aggarwal, Samanpreet Kaur
      Journal of Engineering and Technology 2015 5(1):31-35
      Groundwater is the basic source of irrigation in the state of Punjab. Due to seasonal supply of surface water, groundwater is used dominantly in the state, which has led to the alarming decrease in the water levels. To understand the spatial and temporal pattern of groundwater, a groundwater model for Sirhind Canal Tract of Punjab was simulated using PMWIN. The model was calibrated for the period of 1996-97 to 2000-01 and validated for the period 2001-02 to 2005-06.Recharge due to irrigation and rainfall was estimated in accordance with GEC (1997) methods. Different statistical tests revealed that there was good agreement between observed and simulated hydraulic heads. Sensitivity analysis showed that the model was more sensitive to specific yield then hydraulic conductivity values. The simulated model can be effectively used for sustainable management of water resources.

  • VLSI Design and Investigation of an Area Efficient and Low Power MOD-R2MDC
           FFT for MOMO-OFDM

      Abstract: Kirubanandasarathy Nageswaran, Karthikeyan Kottaisamy
      Journal of Engineering and Technology 2015 5(1):36-40
      In this paper, an area-efficient low power fast Fourier transform processor is proposed for multi input multi output-orthogonal frequency division multiplexing (MIMO-OFDM) in wireless communication system. It consists of a modified architecture of radix-2 (R2) algorithm which is described as modified R2 multipath delay commutation (MOD-R2MDC). OFDM is a popular method for high data rate wireless transmission. This paper describes the very large scale integration design of an area efficient MOD-R2MDC FFT for MIMO-OFDM system targeted to future wireless communication systems. The very high speed integrated hardware description language simulation results have been tested practically by implementing in the Altera development and education-2 field programmed gate array (FPGA) development board. Also the existing OFDM system has been tested with these FFT algorithms and their performances were analyzed with respect to occupation of area in FPGA and power consumption. A low-power and area efficient architecture enables the real-time operations of MIMO-OFDM system.

  • Triple Single Slope and Dual Slope Frequency to Voltage Converter Circuits

    • Authors: Krishnagiri Chinnathambi Selvam
      Pages: 41 - 44
      Abstract: Krishnagiri Chinnathambi Selvam
      Journal of Engineering and Technology 2015 5(1):41-44
      A sinusoidal frequency to voltage converters using op-amp based triple integrators, dual comparator and dual peak detectors, is explained in this paper. The output DC voltage is linearly proportional to the sinusoidal input frequency. The proportional constant is the product values of a resistor, a capacitor and a reference DC voltage. By employing precision values for these three quantities, an acceptable level of accuracy can be achieved. Verification of feasibility of the circuit is established by way of test results.

      Flat-slab structural systems have a large applicability due to their functional and economic advantages. Initially, the reinforced concrete flat slabs had drops and columns with capitals and were considered to be the structures of choice for warehouse construction and heavy loads because shear was not a problem. Flat plates were subsequently developed, with no drops and no column capitals and due to cheaper formwork required, they were popular for residential and office buildings. Flat plate slabs exhibit higher stress at the column connection and are most likely to fail due to punching shear rather than flexural failure. To avoid shear failure, parameters influencing the punching strength need to be clearly investigated by realistic analytical or experimental studies. The present analytical study investigates the influence of some of the parameters governing the behavior of connections under punching shear, which are concrete strength, column aspect ratio, slab thickness and gravity loading. Computer program Structural Analysis Program 2000 V14 is used to model columns and slabs as frame and shell elements, respectively. Parametric studies on aspect ratio and depth-to-span ratio have been carried out using displacement control non-linear static pushover analysis to investigate the influence of these parameters on punching shear capacity of the intermediate and corner column connections, which proved to be the governing criteria to prescribe drift limits for flat plate systems in seismic zones.

      Optimization of composite structures for the design and repair through, in particular, the use of pasted junctions in lieu of bolted or riveted junctions for different applications. The object of this work is to model the durability of a pasted assembly of composite structures under quasistatic loads by the hereditary Rabotnov approach. To do this, it took on the one hand, an experimental analysis of the damage of the adhesive in shear behavior subjected to different loading rates. On the other hand, the establishment of the model required experimental identification of the parameters of the creep kernels in formulating expressions for determining the durability and long-term strength limit in the shear of glued composite assembly. Special attention is paid to the prediction of the strength characteristics of the material under long loading periods up to 10 6 h (approximately 100 years of operation) by laboratory tests carried out for 10 3 h.The results could be useful, in particular, when designing and assembling the elements in composite structures located in bridge decks and walkways (beams, spacers, etc.) and also in shipbuilding.

      Thousands of consumer, commercial, and industrial products can be produced by die casting process with high volume ranging from small to large components and hence die casting can be referred as mass production process. One such component is the lock assembly of a two wheeler which is made of ZAMAK (Zinc alloy) and produced by die casting process. Some of the products produced by die casting was defective and hence needs to improve the performance of the process. The objective of the study was to evaluate the effect of injection pressure of the molten metal, hydraulic pressure, temperature of the molten metal, and the cooling time on the dimensional stability of the lock assembly of two wheeler. In order to study the effect, the process parameters such as injection pressure of the molten metal, hydraulic pressure, temperature of the molten metal, and the cooling time Response Surface Methodology (RSM) with Face Center Design (FCD) was used. The experiments were carried out according to design matrix. Four responses namely slot diameter, pitch circle diameter, pin-hole diameter, and pin-hole depth were used for study. The RSM model was developed for each response. Analysis of variance (ANOVA) for each response was also carried out to find out the significant factors and their interactions. Finally, optimization was carried out and the optimized input parameters were validated by conducting experiments. The modeled and experimental results were compared and an error of 2-7% was observed.
