  • HeatBlocker CoolWrap Exhaust Insulation on a Mobile Crane for the Construction Industry - Case Study

    The temperatures of exhaust streams from diesel-powered construction equipment are often elevated to ensure effective operation of diesel particulate filters, in which collected soot is combusted. As a result, these exhaust systems can become extremely hot, endangering operating personnel and potentially elevating heat deterioration of nearby engine components. This was the problem presented to ...

  • Integration of an evolutionary algorithm into the ensemble Kalman filter and the particle filter for hydrologic data assimilation

    Data assimilation (DA) methods continue to evolve in the design of streamflow forecasting procedures. Critical components for efficient DA include accurate description of states, improved model parameterizations, and estimation of the measurement error. Information about these components are usually assumed or rarely incorporated into streamflow forecasting procedures. Knowledge of these ...

  • Genset locomotive repower project - CSX transportation case study

    In December of 2007, CSX Transportation, in cooperation with PSEG Fossil LLC and NESCAUM, began a project to modernize three conventional switch locomotives to a more efficient and less polluting design.  Each locomotive engine was replaced with two smaller power packs, each equipped with a diesel particulate filter (DPF).  These locomotives are now cleaner, quieter, and more energy ...

  • Particle removal efficiency of Nano alumina fiber filters

    A 2 nanometer alumina fiber is combined with a microglass fiber to produce a nonwoven filter. Its pore size is 2 microns, yet it is functionally rated at 0.03 microns. Data are presented showing dirt holding capacity and filtration efficiency for particles from 0.001 to 7 microns. The filters have high retention for micron size silica dust, bacteria, virus, DNA/RNA, tannin and latex spheres. ...

  • Minimisation of VA loading of UPQC in three–phase four–wire distribution system

    Unified power quality conditioner (UPQC) is a combination of series and shunt active power filters with a common DC link. This device is used to enhance power quality by injecting required amount of Volt–Ampere (VA) into the system. In view of the cost effectiveness, it is desirable to have VA loading of UPQC without compromising the compensation capability. This paper presents a methodology to ...

  • Identification of IIR systems using comprehensive learning particle swarm optimisation

    Adaptive infinite impulse response (IIR) filters are more suitable in modelling real-world systems as they are inherently pole-zero structure and also require less parameters to achieve the same performance level of finite impulse response (FIR) filters. But they are not popular in practice due to lack of practical, efficient and robust global optimisation algorithms. This paper introduces a ...
