  • How FSMA Impacts Food and Beverage Manufacturers

    The food and beverage industry have evolved significantly over the past 10 years. The rules for the FDA’s Food Safety Modernization Act (FSMA) have changed food and beverage manufacturing by having companies focus on preventing their products from being contaminated rather than limiting the scope of contaminations. “FSMA is the largest overhaul of government regulations since the ...

  • Digital Technology to Transform Oil, Gas Hiring Practices

    The oil and gas industry’s effort to adopt digital technology not only will impact its daily operations, but its hiring needs as well. The oil and gas industry must pursue digital technology for two reasons: an aging workforce and increased focus on safety, said Mike Weast, IT regional vice president with professional staffing firm Addison Group, in a statement to Rigzone. As the majority ...

  • Application of the LBM with adaptive grid on water hammer simulation

    A lattice Boltzmann method (LBM) is utilized to solve single-phase transient flow in pipes. In order to eliminate grid limitation related to the method of characteristics, governing equations are modified using appropriate coordinate transformation. The introduced modification removes connection between Courant number and spatial disposition of the computational nodes, forming a more flexible ...

  • Surface Decontamination of PCBs (PCB-laden oil) by DeconGel 1101 and 1102

    Abstract Field testing aboard the USS Missouri maritime museum vessel showed that excellent surface decontamination was achieved by applying DeconGel™ 1102 onto contaminated surfaces, resulting in encapsulation of PCB contaminant by DeconGel's active components. For all contaminated surfaces tested, EPA PCB limit standards (Regulations 761.79, 761.123) of < 10 ug/100 cm2 were ...

  • A complex network approach for identifying vulnerabilities of the medium and low voltage grid

    The vision behind the smart grid promises, among other things, to bring more attention to the lower layers of the distribution network where users are gradually transforming into prosumers. Independent of this transformation, users will expect the same (or higher) level of reliability of the infrastructure. In this paper, we consider physical samples from the Dutch medium and low voltage network ...

  • Cascade failures and distributed generation in power grids

    Power grids are nowadays experiencing a transformation due to the introduction of distributed generation based on renewable sources. At difference with classical distributed generation, where local power sources mitigate anomalous user consumption peaks, renewable sources introduce in the grid intrinsically erratic power inputs. By introducing a simple schematic (but realistic) model for power ...

  • Change 60Hz to 50Hz Power

    In conventional power supplies, the mains is rectified (that means the negative parts of the main cycle are flipped over to become positive). This gives 50 or 60 positive pulses per second. These pulses are used to charge up capacitors that store the charge between top ups. If you put a scope on the capacitor, you will see a sawtooth waveform that shows the top of the pulse, then the voltage ...

  • How did palm oil become such a problem — and what can we do about it?

    Production of this ubiquitous ingredient is devastating for the environment. Solutions are complex, but they are out there. Last August, from the window of a jet high over Sumatra, I counted nearly a dozen plumes of smoke rising from the vast jungles and plantations below. Some more than a half-mile wide, they looked like pillars holding up the sky. That week the ...

  • A new time–frequency approach for hybrid differential and impedance protection of transmission lines

    A new current differential protection of transmission lines is presented in this paper using an S–transform variant having very fast computational speed suitable for real–time applications. The conventional S–transform used earlier for transmission line protection has large computational overhead and thus is not suitable for generating decisions regarding the occurrence of a fault and its type on ...
