Recent supports provided to livestock operations also supported the development of mechanization levels used in these operations. Technological progress especially herd management systems, automatic milking, cleaning and hygiene systems led significant feeding mechanization. Especially during last 10 years, numbers were achieved manufacture feed mixing distribution machines with a great role an...

This article compares the technical and economic indicators of types transportation goods by principle “from door-to-door”. Analyzes choice an effective option. The research considers possibility choosing most efficient option least expensive type transportation, depending on distance weight cargo being transported. Container transport, contrailer road transport rail in covered wagons were sele...

This article deals the implementation of a SiC MOSFETs in three-phase inverter module, intended for use auxiliary converters powering electrical appliances railway wagons. The basic properties semiconductor elements and their differences, compared to IGBT modules, are summarized here. given block diagram describes individual blocks module interconnection.

In this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. In the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. It is assumed that the sequence of the trains in the network is known. The objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...
