Storage vendors routinely benchmark their products in a lab for marketing or internal development. Realizing enterprise storage procurements can run into the millions of dollars, how can an end user organization evaluate various storage subsystems in their environments before signing on the bottom line? Using Storage Performance Council (SPC) benchmarks, this organization tested multiple storag...

In the past several years, we’ve been developing a high performance OCR engine for machine printed Chinese/English documents. In this paper, we present two innovative techniques that contribute to the high efficiency in recognition of the mixed Chinese/English text line. They are (1) a progressive search strategy based on character verification, and (2) a tree-based fast match technique with a ...

Constraint Programming (CP) is a very general programming paradigm that proved its efficiency on solving complex industrial problems. Most real-life problems are stochastic in nature, which is usually taken into account through different compromises, such as applying a deterministic algorithm to the average values of the input, or performing multiple runs of simulation. Our goal in this paper i...

Real-time ETL (Extraction, Transformation and Loading) of enterprise data is one of the foremost features of next generation Business Intelligence (BI 2.0). This paper presents a proposal for loading operational data in real time using a Data Warehouse (DW) architecture with faster processing time than current approaches. Distributed database techniques, like derived horizontal fragmentation in...

This paper presents the results of an evaluation of a toxicity mitigation control strategy using the IWA simulation benchmark (Copp et al., 2002; Copp, 2001). The aim of the proposed strategy is to minimise the impact of a toxic influent shock load on process performance. To do this, the strategy makes use of a respiration rate measurement to detect toxic events and uses an equalisation tank to...

There are two concurrent paths in a typical cache access — one through the data array and the other through the tag array. In most cases, the path through the tag array is significantly longer than that through the data array. In this paper, we propose a new scheme that exploits this imbalance in the tag and data paths to improve overall cache performance. Under this scheme, an additional tag d...

Perfectly matched layer (PML) absorbing boundary condition (ABC) is an important technique in finitedifference time-domain (FDTD) when simulating infinite area's electromagnetic behaviour in finite area. A big enough computational area was designed in which there is no influence of reflective wave. The radiation of sinusoidal line source in this area was the benchmark for assessment of reflecti...

We suggest a system for recognizing handwriting text from a whiteboard. In contrast to the mainstream approaches, we are able to recognize text solely from still images and do not require additional hardware or tracking of the writer’s hand. The proposed system contains extraction of text areas, suitable image preprocessing steps, line extraction, and finally text recognition. Since we are deal...

This paper is based on a path planning approach we reported earlier for industrial robot arms with 6 degrees of freedom in an on-line given 3D environment. It has online capabilities by searching in an implicit and descrete configuration space and detecting collisions in the Cartesian workspace by distance computation based on the given CAD model. Here, we present different methods for specifyi...
