The grain elevator was erected around 1940 and is situated at the Odra River embankment. It has a rectangular plan with longer side perpendicular to former port wharf. structure of building mixed, made reinforced concrete brick masonry. entire facility founded on foundation slab. ground floor columns, supporting silos, walls floor, above silo drainage funnels, inter-story ceilings technical rou...

A number of considerations should be taken into account in design stage to avoid the foregoing malfunctions of vertical silos containing ore concentrate. One of the silo problems is obstruction at the outlet which blocks the material flow. There are procedures, depending on the material properties and silo dimensions, to solve this problem. A common way is impacting the silo wall by manual hamm...

We study the formation of shocks on the surface of a granular material draining through an orifice at the bottom of a quasi-two-dimensional silo. At high flow rates, the surface is observed to deviate strongly from a smooth linear inclined profile, giving way to a sharp discontinuity in the height of the surface near the bottom of the incline, the typical response of a choking flow such as enco...

A model for slow accumulation of granular matter in a silo is considered. For the case of a circular silo with central point source the prooles of the standing and rolling layers are explicitly computed. The computed shapes agree qualitatively with experimental observations and seem better justiied than results with constant speed of the rolling layer.

Data Deduplication is becoming increasingly popular in storage systems as a space-efficient approach to data backup and archiving. Most existing state-of-the-art deduplication methods are either locality based or similarity based, which, according to our analysis, do not work adequately in many situations. While the former produces poor deduplication throughput when there is little or no locali...

In this paper we present a new polynomial function for calculating the local phase transformation temperature (Ae3 ) between the austenite+ferrite and the fully austenitic phase fields during heating and cooling of steel:[Formula: see text] The dataset includes the terms of the function and the values for the polynomial coefficients for major alloying elements in steel. A short description of t...

Vertical silos are large cylinders used for material storage in agriculture and mineral industries. One of the silo problems is its obstruction due to dome and dense packing. Depend on the material properties and silo dimensions several techniques are used to solve this problem. In the present work, possibility of obstruction solution of a laboratory silo by ball impact is investigated. Test ma...
