The DWS (Data Warehouse Striping) technique is a data partitioning approach especially designed for distributed data warehousing environments. In DWS the fact tables are distributed by an arbitrary number of low-cost computers and the queries are executed in parallel by all the computers, guarantying a nearly optimal speed up and scale up. Data loading in data warehouses is typically a heavy pr...

Arvand is a stochastic planner that uses Monte Carlo random walks (MRW) planning to balance exploration and exploitation in heuristic search. Herein, we focus on the latest developments of Arvand submitted to IPC’11: smart restarts, the online parameter learning system, and the integration of Arvand and the postprocessing system Aras.

OBJECTIVES Authors may choose to work with professional medical writers when writing up their research for publication. We examined the relationship between medical writing support and the quality and timeliness of reporting of the results of randomised controlled trials (RCTs). DESIGN Cross-sectional study. STUDY SAMPLE Primary reports of RCTs published in BioMed Central journals from 2000...

In this paper we proved that every g-Riesz basis for Hilbert space $H$ with respect to $K$ by adding a condition is a Riesz basis for Hilbert $B(K)$-module $B(H,K)$. This is an extension of [A. Askarizadeh, M. A. Dehghan, {em G-frames as special frames}, Turk. J. Math., 35, (2011) 1-11]. Also, we derived similar results for g-orthonormal and orthogonal bases. Some relationships between dual fra...

BACKGROUND An increasing number of people involved in medicine are under pressure to publish research, but there is little understanding of how to describe structured writing. AIM This paper aims to describe the structure of original research papers published in the British Journal of General Practice with a view to providing insight into the nature of such analyses, and particularly to help ...

Holmgren E. 2006. Forest Commons in Boreal Sweden – Influences on Forest Condition, Management and the Local Economy. This thesis examines the influences of Swedish forest commons on forest condition, management and the local economy. The approach is rationalistic, i.e. outcomes of forestry activities are assessed in relation to aims. According to the stated objectives, forest commons should se...

PURPOSE Edwin Beer introduced the first endoscopic treatment of papillary bladder tumors in 1910. This historical review describes how his landmark discovery paved the way for office cystodiathermy to treat recurrent papillary tumors. MATERIALS AND METHODS The medical writings of Edwin Beer and all studies pertaining to the treatment of papillary bladder tumors from 1879 to the present were r...

Patterns of Protocols are introduced for describing communication across networks, providing conceptual patterns for behaviors of protocols and common terminology for their operations. The two basic structural patterns are Protocol-ProviderPeer-Pair-Packet and User-Provider-Agent, orthogonal to one another. The first views protocols in a common manner related to instances at each node, addresse...
