Outsourcing and innovations are very sensitive matters for people dealing with agriculture, especially in the case of farmsteads, which are producing safe food. Food should be same and manageable at the same time. There are currently various definitions of safe food, especially in the case of organic food. In order to fulfil this condition, there is a need for closer co-operation between the farmsteads and the entities in the agricultural sector. As consequence of this approach, the notion of outsourcing is beginn...

The construction of some large industrial units and their endowment with oversized and heavy technological equipments, as well as their regular repair or replacement, led to the necessity of transporting some parts that exceeded both the gauge and the tonnage admitted on public roads. The choice of the route and the transport scheme (on one or more trailers) was made in such a way that requests would be as few as possible in order not to exceed the carrying capacity of the roads and bridges. However, in many cases...

One of the frequent problems that needs to be addressed when mining coal deposits is the presence in the working face of cohesive materials having high mechanical strength in relation to the average rock to be excavated. These are generally called пїЅhard formationsпїЅ or пїЅhard inclusionsпїЅ and are in the form of either continuous layers or boulders. This problem is of particular importance in Europe where lignite deposits are exploited in large opencast mines utilizing Bucket Wheel Excavators (BWEs) as the mai...

Conveyor belt loop operates in a system comprising a series of belt segments and the splices between them. Splices are the weakest parts of a loop. Depending on the splicing technology, the spliceпїЅs strength, durability and reliability may vary significantly. Vulcanized splices offer the highest strength and durability. In the case of steel cord belts, such splices are practically the only technology available. In the case of textile belts, adhesive and mechanical splices may also be used. Although mechanical sp...

The authors have revealed particularities in destruction of the rock mass by the system of borehole charges and substantiated the least seismic hazardous blasting schemes which allow decreasing out-contour disturbances and providing more qualitative crushing of rock mass. It has been shown that for the boreholes with 250 mm diameter the least seismic hazardous blasting scheme is one with borehole line placed at the angle of 105пїЅ to the bench wall. At that, the stress level in the out-contour rock mass decreases ...

Urban transit system planning in large cities requires information about demands on passenger transfers. These demands are commonly represented as an origin-destination matrix (O-D matrix) that contains aggregated data of passenger turnover and traffic. Information, needed for these representations to be constructed, is usually collected using analytical models and natural surveys. Unfortunately, these methods do not provide necessary precision for high quality transport system management and are also quite expens...
