There are a variety of recipe recommendation methods based on user's preferences, nutrition balance, or user's health condition. However, there is little study on recipe recommendation considering flavor preferences of regional cuisines, which is helpful for a restaurant to plan on launching dishes from other regions, and to be well received by the local people. Therefore, we propose a method to recommend...
The distributed database HBase has become an effective solution of storing massive data. But there are still no standard methods of designing HBase tables from a conceptual model for an application. This paper presents a mechanism for transforming an E-R model into HBase tables. It defines four types of transforming processes for entities, one-to-one relationship, one-to-many relationship and many-to-many...
In order to study the performance of MIC-GPU-CPU hybrid computing platform, this paper conduct a whole heart simulation model on this platform. And to corroborate the advantages of this heterogeneous architecture environment, we parallelize the electrocardiograms simulation algorithm. Electrocardiograms simulation algorithm is a recommendable case to study the ability of MIC-GPU-CPU architecture for...
Multi-core CPU and GPU technologies upgrades a PC to a personal supercomputer. Many algorithms have been proposed to achieve dynamic scheduling in CPU-GPU hybrid environments. Among them, only pure self-scheduling (PSS) can achieve perfect load balancing in this extremely heterogeneous environment. But PSS can not take full advantage of GPU performance, reduce the overhead of the tail problem, and...
With the fast growing of open source software, more and more software is built through the combination of reusable components and its own proprietary code. While open source software is free, it still come with license obligations that must be met. This paper proposes a process of programmers' claims of the certificate of origin (COO) of source code and a workflow of the tool-based verification of...
In healthcare information exchange (HIE) environments, a publish/subscribe system for the selective and dynamic dissemination of information becomes more and more important due to increasing demand for timely and accurate data sharing among healthcare enterprises. Integrating the Healthcare Enterprise (IHE) proposes a general framework for defining publish/subscribe interactions, and a subscription...
Biological computations like electrocardiological modelling and simulation usually require high-performance computing environments. This paper introduces an implementation of parallel computation for computer simulation of electrocardiograms (ECGs) in a personal computer environment with an Intel CPU of Core (TM) 2 Quad Q6600 and a GPU of Geforce 8800GT, with software support by OpenMP and CUDA. It...
The concept of brain-computer interface (BCI) has emerged over the last three decades as a promising alternative to the existing interface methods. However the BCI framework generally spoken only emphasizes on the aspects of BCI signal processing, lacking of the function of visualization and virtual reality (VR) feedback. This paper designs a general and extendable framework which has the ability...
Health information exchange (HIE) across multiple organizations via the Internet is a current trend in medicine and healthcare. Protection of the sensitive data contained in health information from disclosure to unauthorized persons is challenging. In this paper, we present an access control architecture based on XACML and SAML to address privacy and security issues in our HIE application, Web-based...
Sequential electrocardiograms (ECGs) are very useful for personalized diagnosis. It is therefore very useful to search various electrocardiographs or ECG management systems connected to the Internet for a particular patient's ECGs. This is an interesting but not completely solved problem. In this paper, we present an experimental study of our metadata registry aimed at facilitating the search for...
This paper presents a parallel algorithm using GPU for computer simulation of Electrocardiogram (ECG) based on a 3-dimensional (3D) whole-heart model. The computer heart model includes approximately 50,000 discrete elements (model cells) inside a torso model represented by 344 nodal points with 684 triangular meshes. After the excitation propagation is simulated in the heart model, the Poisson question...
Network-based data sharing is a current trend in medicine and healthcare. The search and retrieval architecture (SRA) we previously proposed for web-based sharing of electrocardiogram (ECG) facilitates the search and retrieval of ECG across hospitals via the Internet. The SRA has a triangle-like configuration including an ECG metadata registry, an ECG provider and an ECG querist. In this paper, we...

The computer heart model includes approximately 50,000 discrete elements (model cells) inside a torso model represented by 344 nodal points with 684 triangle meshes. The Poison question is applied to the volume conductor problem for simulation of ECG, which involves...
