Measurements show that silo wall pressures exhibit large fluctuations in time and space during discharge of the silo. This observation is important for the design of the silo wall because spatial pressure variations may impose substantial bending moments that otherwise may be small or vanishing due to the carrying ability of the membrane forces in the silo wall. Information about the stochastic...

We report experimental observations of sound waves in a granular material during resonant silo discharge called silo music. The grain motion was tracked by high-speed imaging while the resonance of the silo was detected by accelerometers and acoustic methods. The grains do not oscillate in phase at neighboring vertical locations, but information propagates upward in this system in the form of s...

Silos are structures that are used for storing different types of granular material. Dynamic behavior of silos under seismic loads is very complex. In this paper seismic behavior of steel silos with different height to diameter ratios is investigated by considering granular material-structure interaction using ABAQUS finite element package. Silo wall is modeled by shell elements and its behavio...

Many cloud applications need predictable completion of application tasks. To achieve this, they require predictable completion time for network messages. We identify three key requirements for such predictability: guaranteed network bandwidth, guaranteed per-packet delay and guaranteed burst allowance. We present Silo, a network architecture for public cloud datacenters that offers these guaran...

This paper presents research towards the formal speciication and veriication of a secure distributed system and secure application programs that run on it. We refer to the whole system | from hardware to application programs written in a concurrent programming language | as the Silo, and to a simpliied view of the Silo as the miniSilo. Both miniSilo and Silo consist of a collection of microproc...

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...
