We present experimental and numerical results of the effect that a partial discharge has on the morphological and micro-mechanical properties of non-spherical, convex particles in a silo. The comparison of the particle orientation after filling the silo and its subsequent partial discharge reveals important shear-induced orientation, which affects stress propagation. For elongated particles, th...

This paper reports on initial steps of an integration of the microscopic land-use simulation system SILO (Simple Integrated LandUse Orchestrator) and the agent-based transport simulation system MATSim (Multi-Agent Transport Simulation). It is shown how information can be transferred from the land-use model to the transport model in an agent-oriented fashion and how MATSim can be used as a trans...

The effects of storage period and aerobic deterioration on the bacterial community were examined in Italian ryegrass (IR), guinea grass (GG), and whole-crop maize (WM) silages. Direct-cut forages were stored in a laboratory silo for 3, 7, 14, 28, 56, and 120 d without any additives; live counts, content of fermentation products, and characteristics of the bacterial community were determined. 2,...

Silo is a new in-memory database that achieves excellent performance and scalability on modern multicore machines. Silo was designed from the ground up to use system memory and caches efficiently. For instance, it avoids all centralized contention points, including that of centralized transaction ID assignment. Silo’s key contribution is a commit protocol based on optimistic concurrency control...

The grain level in a silo is commercially important. In this work, a novel method is presented to detect the grain level in a silo. Existing methods are generally based on approximations, due to grain dust in the silo. The method proposed here eliminates the effect of grain dust and gives the accurate reading of the grain level. The method is based on the measurements of capacitances of paralle...

Wind induced ovalling vibrations have been reported to occur on several empty, flexible silo structures in group arrangement. The focus in this paper is on the numerical prediction of this phenomenon by simulating the wind flow around a single silo and taking into account the interaction of the wind flow with the structural response. The importance of the 3D turbulent wind flow and wake effects...

Various spoilage microorganisms (bacteria, yeasts and molds) readily grow on crops going into a silo, causing losses in dry matter and quality. To prevent these various microorganisms from growing, two conditions are needed in the silo: an oxygen-free (or anaerobic) environment and a low pH. Many of the oxygen-requiring (aerobic) microorganisms that heat the silage as well as causing losses can...
