We propose a nonparametric data-driven algorithm called DDM for the management of stochastic periodicreview multi-product inventory systems with a warehouse-capacity constraint. The demand distribution is not known a priori and the firm only has access to past sales data (often referred to as censored demand data). We measure performance of DDM through regret, the difference between the total e...

deformation pattern of the northeastern part of the iranian-arabian collision zone (i.e., mainly sanandaj-sirjan belt or zone) is the main concern of this paper. here, we investigate the stress distribution and displacement pattern of eghlid-deh bid area as affected by the position of zagros suture using a three dimensional mechanical model. the modeled area is located between the zagros thrust...

The long latencies introduced by remote accesses in a large multiprocessor can be hidden by caching. Caching also decreases the network load. We introduce a new class of architectures called Cache Only Memory Archi-tectures (COMA). These architectures provide the programming paradigm of the shared-memory architectures, but have no physically shared memory; instead, the caches attached to the pr...

The widely distributed “Step-type” landslides in the Three Gorges Reservoir (TGR) area have caused serious casualties and heavy economic losses. prediction research of landslide displacement will be beneficial to establishment local geological hazard early warning systems for realization scientific disaster prevention mitigation. However, number observed data like displacement, rainfall, reserv...

Understanding membrane protein folding and stability is required for a molecular explanation of function and for the development of interventions in membrane protein folding diseases. Stable aqueous detergent solutions of the Escherichia coli glycerol facilitator in its native oligomeric state have been difficult to prepare as the protein readily unfolds and forms nonspecific aggregates. Here, ...

We introduce a domain decomposition structure-preserving method based on hybrid mimetic spectral element for three-dimensional linear elasticity problems in curvilinear conforming structured meshes. The is an equilibrium which satisfies pointwise of forces. established through hybridization first allows inter-element normal stress discontinuity and then enforces the continuity using Lagrange mu...

In designing a multiprocessor architecture, the motivating factors are that the architecture should be general purpose, easier to program and at the same time scalable. The Data Diffusion Machine (DDM) seeks to fulfil such criteria. The DDM provides shared-data access on distributed memory hardware, allowing data to freely migrate to processors on demand. The DDM concept was originally proposed...

Standard Arbitrary Lagrangian-Eulerian (ALE) methods for the simulation of fluid-structure interaction (FSI) problems fail due to excessive mesh deformations when the structural displacement is large. We propose a method that successfully deals with this problem, keeping the same mesh connectivity while enforcing mesh alignment with the structure. The proposed Extended ALE Method relies on a va...

Multi-Agent Systems (MAS) offer an architecture for distributed problem solving. Distributed Data Mining (DDM) algorithms focus on one class of such distributed problem solving tasks—analysis and modeling of distributed data. This paper offers a perspective on DDM algorithms in the context of multiagents systems. It discusses broadly the connection between DDM and MAS. It provides a high-level ...
