    Reliability Evaluation and Prediction of Heavies Up Gradation Plant in IREL, Chavara

    by J. Abdul Jaleel, Anju Iqubal, Rahana P.

     

    Abstract - In industries the reliability engineering place a major role in process availability, safety, probability of failure component etc. Here the plant at Indian Rare Earth Limited is chosen for reliability evaluation. The technique used for the reliability evaluation is fault tree analysis. Open FTA software is used for fault tree analysis. In this paper reliability and failure rate predictions are also carried out using artificial neural network. Here working environment used for ANN is neural lab. .

    Reliability Evaluation and Failure Rate Prediction of Ilmenite Fluidized Bed Dryer at IREL, Chavara

    by J. Abdul Jaleel, Minchu Vijayan

     

    Abstract - In industries the reliability engineering plays a vital role in process availability, safety and probability of failure components. So this paper is based on the reliability analysis of a process industry. Reliability is the probability that a device continues to perform a particular function over a particular period of time and under stated conditions. Here the plant at Indian Rare Earths Limited is chosen for reliability evaluation. The technique used for the reliability evaluation is fault tree analysis. The approach is based on Fault Tree Analysis (FTA), which is a technique used to obtain the probability of occurrence of an undesired event. Open FTA is the software, used for the Fault tree analysis. This paper also describes the Reliability and Failure rate predictions using Artificial Neural Networks. The working environment used for ANN is Neural LAB.

    Kilobyte Virtual Machine Memory Management

    by Adamou Souleymane Aboubacar

     

    Abstract - Java Virtual Machines use various automatic garbage collector algorithms to manage memory in the object lifecycle. However, these algorithms have some drawbacks. In order to improve embedded systems memory management, we implement a new garbage collector algorithm on Kilobyte Virtual Machine. This algorithm apply the mark-sweep and compaction of the memory garbage collection in pages most used in the recent past, and the mark-sweep garbage collection without compacting the memory in pages used the least in the near past.

    Real Time Performance Analysis of DBA Algorithm Using Network Processors

    by S. Ramya, N. Nagarajan, B. Kaarthick

     

    Abstract - A new framework for Ethernet Passive Optical Network (EPON) is proposed wherein the Dynamic Bandwidth Allocation (DBA) estimation is shared by the Optical Line Terminal (OLT) and Optical Network Units (ONU) thereby reducing the load on the OLT and reducing the delay and improving the bandwidth utilization. The proposed framework was evaluated under heavy load conditions and with the help of OPNET simulations it has been demonstrated that our framework outperforms the conventional scheme in terms of throughput, percentage of utilization and other QoS services. However, in order to employ the algorithm for commercial purpose, the performance of the algorithm should be evaluated in a WiMAX switch to verify its hardware compatibility. This paper focuses on implementing and testing the performance of the DDA-EPON (Distributed DBA) algorithm in a WiMAX switch using the Intelís IXP 2400 Network Processor. The performance of the algorithm is further compared with the conventional process in terms of machine clock cycles before arriving at conclusions.

    Towards the Improvement of Emergency Call Service

    by Miha Ristič, Franc Novak

     

    Abstract - This paper describes the initial steps for the improvement of emergency call service. For instance, persons reporting an accident or similar event and the officer receiving the call are often under stress, which distracts the communication process and becomes a barrier to information transfer. We try to identify the main deficiencies when processing a received call and explore alternative ways of recording the main information content. In this regard we performed usability test case study for assessing the efficiency of recording information either on a blank paper or in a prepared paper form. Implementation details of the usability test are described.
