An overview of the MHONGOOSE survey: Observing nearby galaxies with MeerKAT

MHONGOOSE is a deep survey of the neutral hydrogen distribution in a representative sample of 30 nearby disk and dwarf galaxies with HI masses from 10^6 to ~10^{11} M_sun, and luminosities from M_R ~ -12 to M_R ~ -22. The sample is selected to uniformly cover the available range in log(M_HI). Our extremely deep observations, down to HI column density limits of well below 10^{18} cm^{-2} - or a few hundred times fainter than the typical HI disks in galaxies - will directly detect the effects of cold accretion from the intergalactic medium and the links with the cosmic web. These observations will be the first ever to probe the very low-column density neutral gas in galaxies at these high resolutions. Combination with data at other wavelengths, most of it already available, will enable accurate modelling of the properties and evolution of the mass components in these galaxies and link these with the effects of environment, dark matter distribution, and other fundamental properties such as halo mass and angular momentum. MHONGOOSE can already start addressing some of the SKA-1 science goals and will provide a comprehensive inventory of the processes driving the transformation and evolution of galaxies in the nearby universe at high resolution and over 5 orders of magnitude in column density. It will be a Nearby Galaxies Legacy Survey that will be unsurpassed until the advent of the SKA, and can serve as a highly visible, lasting statement of MeerKAT's capabilities

Logistiese beplanning met behulp van simulasiemodellering: 'n Gevallestudie

This article gives an overview of the combined use of object-oriented programming and simulation, with the objective of analysing and planning the logistic functions of a firm. An object-oriented simulation approach is used to evaluate the reception and distribution function of a courier firm. Both the reception of and operations (sorting) on the parcels in the plant were simulated. The first objective of the firm was to analyse the productivity of the conveyer belts and workers in the sorting plant of the courier firm. The firm's utilisation of most of its resources is fairly good, but it is possible to obtain a more efficient process by restructuring its activities. Results from the simulation study showed an imbalance in the capacities of the workstations. Some of the workers, especially those to the end of the conveyer belts, spent almost all of their time waiting for parcels to reach them, while those at the beginning were working at maximum capacity. This is mainly due to the layout and structure of the system. The biggest bottleneck in the system was the capacity of the coupling between two of the conveyer belts. The conclusion was that the firm should seriously consider redesigning the plant. This is the first computer model of the firm's business activities that can be used as a planning tool, and fills a gap in its current planning function. This simulation can be used to determine where and how workers should be applied in the sorting process. The complete simulation model reaches its potential when used as a strategic operational tool, by forecasting the expected results from changing operations and plant layout. A new plant layout has been proposed to the firm, which the model shows to result in substantial improvements in the productivity of the workers, allowing a reduction in their numbers
