A cane harvesting system which eliminates the use of chain slings has been developed on Illovo's mill-cum-planter estate. A semi-mechanised "split harvesting system" has been adopted. Conventional type trailers are used for infield haulage which off-load loose cane into windrows on the loading banks. Grabloaders then transload the cane from the windrow into "Hilo" cane lorries for transportatio...

A video sequence is first mapped to a sequence of points in a semi-metric space that forms a polyline. We require only that a semi-distance between pairs of points be defined that need not satisfy the triangle inequality. By simplifying the polyline, we obtain a small set of the most relevant key frames that is representative of the whole video sequence. The degree of the simplification is eith...

We propose a dynamic model for optimizing the ows of atcars that considers explicitly the broad range of complex constraints that govern the assignment of trailers and containers to a atcar. The problem is formulated as a logistics queueing network which can handle a wide range of equipment types and complex operating rules. The complexity of the problem prevents a practical implementation of a...

The author provides an outline of the basic procedure for cleaning and disinfecting road transport vehicles, with special attention to the types of cleaning agents which may be used.

This paper considers the parcel hub scheduling problem (PHSP) with unequal batch size inbound trailers, which is a combinatorial optimization problem commonly found in a parcel consolidation terminal in the parcel delivery industry (PDI). The problem consists of processing a large number of inbound trailers at a much smaller number of unload docks. The parcels in the inbound trailers must be un...

Film trailers have specific features defining a distinct visual media genre. Trailer structural features and viewers’ parsing strategies were analyzed in 21 trailers – a set of comedy, drama, and action film per decade from 1940 2010. Trailers’ structural features show a shot duration pattern that replicates the gradual decrease in Hollywood film over the same period (Cutting et al., 2011; Salt...

Supervisors in a less-than-truckload freight terminal establish material flows inside the terminal by assigning incoming trailers to open doors. A common scheduling strategy is to look ahead into the queue of incoming trailers and assign them to doors to minimize worker travel. We develop a model of the resulting material flows and use it to construct layouts that exploit this type of schedulin...

Within V4 automotive Global Value Chains (GVCs), technologies absorbed by the corporate sector represent a significant impact on level of value-added created within economy. Sectoral and geographic targeting our research is determined export motor vehicles, trailers, semi-trailers produced in countries. The article’s main objective was to investigate role services provided countries GVCs ...
