We describe two uses of meta-level inference: to control the search for a proof;and to derive new control information, and illustrate them in the domain of algebraic equation solving. The derivation of control informa...

As large shape repositories become more common, the problem of automatically generating good views of shapes has recently gained prominence. However very few of the proposed methods take into account the orientation of the shape in the resulting view, and none presents a satisfactory solution. In this paper we present a simple, example based method to correct the orientation of a shape in a query image. Our method depends on the availability of a database of classified images containing correctly oriented shapes. In the first step, a candidate class for the query shape is identified, and in the second, the query shape is aligned with. a target shape from the candidate class.

Businesses often need to query visually rich documents (VRDs), e.g., purchase receipts, medical records, and insurance forms, among many other forms from multiple vendors, to make informed decisions. As such, several techniques have been proposed to automatically extract independent entities of interest front VRDs such as extracting price tags from purchase receipts, etc. However, for extracting semantically linked entities, such as finding corresponding price tags for each item, these techniques either have limited capability in handling new layouts, e.g., template-based approaches, or require extensive amounts of pre-training data and do not perform well, e.g., deep-learning approaches. In this work, we introduce a program synthesis method, namely VRDSYNTH;to automatically generate programs to extract entity relations from multilingual VRDs. Two key novelties, which empower VRDSYNTH to tackle flexible layouts while requiring no pre-training data for extracting entity relations, include: (1) a new domain-specific language (DSL) to effectively capture the spatial and textual relations between document entities, and (2) a novel synthesis algorithm that makes use of frequent spatial relations between entities to construct initial programs, equivalent reduction to prune the search space, and a combination of positive, negative, and mutually exclusive programs to improve the coverage of programs. We experiment on two popular VRD understanding benchmarks, namely FUNSD and XFUND, on the semantic entity linking task, consisting of 1,592 forms in 8 different languages. VRDSYNTH, despite having no prior pre-training data, outperforms the s tate-of-theart pre-trained deep-learning approaches- LayoutXLM, I nfoXLMB, and XLMRobertaBase in 5, 6 and 7 out of 8 languages, respectively. Noticeably, in English. VRDSYNTH improves 42% of Fl score over LayoutXLM while being complementary to LayoutXLM in 7/8 languages. We further extend VRDSYNTH with automated table recognition, namely V

Program examples from the textbook "Digital Signal Processing and Applications with the OMAP-L138 eXperimenter" have been ported to the OMAP-L138 LCDK, enabling this inexpensive development kit to be considered as an alternative to the LogicPD Zoom eXperimenter. A small number of new program examples has been added, further demonstrating features of the AIC3106 codec and of the C6748 EDMA3 controller.

On-demand computing, Software-as-a-Service, Platform-as-a-Service, and in general Cloud Computing is currently the main approach by which both academic and commercial domains are delivering systems and content. Nevertheless there still remains a huge segment of legacy systems and application ranging from accounting and management information systems to scientific software based on classic desktop or simple client-server architectures. Although in the past years more and more companies and organizations have invested important budgets in translating legacy apps to online cloud-enabled environment there still remains an important segment of applications that for various reasons (budget related in most cases) have not been translated. This paper proposes an innovative pipeline model architecture for automated translation and migration of legacy application to cloud-enabled environment with a minimal software development costs.

In this paper a novel family of maximum-period Nonlinear Congruential Generators (NLCGs) based on the digitized Sawtooth map is considered for the definition of hardware and software efficient Pseudo Random Number Generators (PRNGs). A list of such maximum period NLCGs for period lengths up to 2(31)-1 is provided. Referring to the NIST800-22 statistical test suite, a PRNG example based on the combination of two of the proposed NLCGs is presented and discussed.
Peephole optimizers are typically constructed using human-written pattern matching rules, an approach that requires expertise and time, as well as being less than systematic at exploiting all opportunities for optimiz...

This paper presents a new approach for the development of data-intensive web applications that depend on sophisticated application logic. E-Commerce web sites, on-line auction systems and large enterprise web portals fall into this category as they require comprehensive data access, data processing and data manipulation capabilities. However, existing methodologies mainly concentrate on modeling content, navigation and presentation aspects of read-only web sites. In our opinion these models are not sufficient to express complex operations that access or modify web application content. Therefore, we propose an additional Operation Model defining the operation logic of a web application. We show that based on this model a significant part of a web application's Operation Layer can be generated, still allowing the manual implementation of arbitrary additional functionality. We evaluate our approach and present experimental results based on a large example application for the area of innovation management.
