VIDOS is a java-based server-client video management system that permits one to customize a personal version of any downloadable digital video file over the Internet or local intranet. It enables one, without purchasing expensive video editing software, to edit the video spatially and temporally, to specify the desired zoom factor, frame rate and video format, and to choose the nature and quality of digital compression before downloading the edited video. VIDOS permits videos to be adapted to suit their end uses. By potentially reducing their size, it can improve corporate and personal efficiency by speeding network transfers and cutting disc storage requirements. (C) 2000 Elsevier Science B.V.

Due to its relative newness and popularity, java is being taught to numerous non-novice programmers both in industry and in academia. Claims have been made that certain background characteristics of programmers relate to ease in learning java. In this study, background information of 135 non-novice programmers was obtained, together with data relating to their difficulty of learning several different features of java. Results of this study could be used by software project managers contemplating the use of java, and by academicians involved in curricular planning. (C) 2003 Published by Elsevier B.V.

Hypertension and arrhythmia are chronic diseases, which can be effectively prevented and controlled only if the physiological parameters of the patient are constantly monitored, along with the full support of the health education and professional medical care. In this paper, a role-based intelligent mobile care system with alert mechanism in chronic care environment is proposed and implemented. The roles in our system include patients, physicians, nurses, and healthcare providers. Each of the roles represents a person that uses a mobile device such as a mobile phone to communicate with the server setup in the care center such that he or she can go around without restrictions. For commercial mobile phones with Bluetooth communication capability attached to chronic patients, we have developed physiological signal recognition algorithms that were implemented and built-in in the mobile phone without affecting its original communication functions. It is thus possible to integrate several front-end mobile care devices with Bluetooth communication capability to extract patients' various physiological parameters [such as blood Pressure, pulse, saturation of haemoglobin (SPO2), and electrocardiogram (ECG)], to monitor multiple physiological signals without space limit, and to upload important or abnormal physiological information to healthcare center for storage and analysis or transmit the information to physicians and healthcare providers for further processing. Thus, the physiological signal extraction devices only have to deal with signal extraction and wireless transmission. Since they do not have to do signal processing, their form factor can be further reduced to reach the goal of microminiaturization and power saving. An alert management mechanism has been included in back-end healthcare center to initiate various strategies for automatic emergency alerts after receiving emergency messages or after automatically recognizing emergency messages.

Modeling cooling of ready-to-eat meats by 3D finite element analysis: Validation in meat processing facilities

引用

JOURNAL OF FOOD ENGINEERING 2013年第2期116卷 450-461页

作者： Cepeda, J. F. Weller, C. L. Thippareddi, H. Negahban, M. Subbiah, J. Univ Nebraska Dept Biol Syst Engn Lincoln NE 68583 USA Univ Nebraska Dept Food Sci & Technol Lincoln NE 68583 USA Univ Nebraska Dept Mech & Mat Engn Lincoln NE 68588 USA

A three-dimensional (3D) finite element model for simulating heat transfer during cooling of irregular-shaped ready-to-eat meat products was developed and validated. The heat transfer model considered conduction as the governing equation, subject to convection, radiation and moisture evaporation boundary conditions. A 3D finite element algorithm developed in java (TM) was used to solve the model. The algorithm generated solutions for meshes containing 4-node tetrahedral volume elements and 3-node triangular boundary elements. Product geometries were generated from CT-scan images of the meat products. The model was adapted to receive input parameters that can be easily provided by a meat processors including air relative humidity, air temperature, air velocity, type of casing, duration of water shower, product weight, and estimated core temperature of product prior to entering the cooling chamber. Model validation was conducted in four commercial facilities, under normal processing conditions. Temperatures predicted by the model were in agreement with observed values. Average root-mean-square error (RMSE) was 1.19 +/- 0.54 degrees C for core temperatures, 1.73 +/- 0.48 degrees C for temperatures 0.05 m from core to surface, and 2.01 +/- 1.01 degrees C for surface temperatures. The developed heat transfer model was integrated with predictive microbiology models through a food safety website: ***. The integration can be useful for estimating the severity of cooling deviations and resulting microbiological safety caused by unexpected cooling process disruptions. (C) 2012 Elsevier Ltd.

Cognitive support through visualization and focus specification for understanding large class libraries

引用

JOURNAL OF VISUAL LANGUAGES AND COMPUTING 2009年第1期20卷 50-59页

作者： Ali, Jauhar King Fahd Univ Petr & Minerals Coll Comp Sci & Engn Dept Informat & Comp Sci Dhahran 31261 Saudi Arabia

Effective object-oriented (OO) programming requires understanding class libraries. This paper presents our approach to design and build a cognitive tool that supports a programmer to understand OO class libraries. The MUDRIK system provides (1) three-dimensional visualization mechanisms for representing class structures and relationships from a variety of views and (2) flexible focus specification mechanisms that allow users to adapt a space of components to be displayed according to the task at hand. Interactive views of MUDRIK enable programmers to examine components' detail while maintaining a global representation of the rest of the library. The paper describes why understanding class library is critical in OO programming, presents a cognitive framework of our approach and design rationale behind the system design, and provides a detailed description of the system followed by a discussion on our approach.

作者： Phanouriou, C Abrams, M Department of Computer Science Virginia Tech Blacksburg VA 24061-0106 USA

A method to add a Web-based interface to a command-line driven system is presented. Without programming, javamatic can generate a graphical user interface, then invokes commands in the legacy system transparently to the user. The user interface (UT) is automatically generated as a java applet or stand-alone interface from a high-level description of the application, which is UI independent, using a set of UI mapping rules. The application is wrapped with an interface server;thus multiple clients can use the legacy application through the Web. (C) 1997 Published by Elsevier Science B.V.

We report on the development of a java-based application devised to support collaborative teaming of Art concepts and ideas over the Internet. Starting from an examination of the pedagogy of both Art education and collaborative learning we propose principles which are useful for the design and construction of a "lightweight" software application which supports interactive Art learning in groups. This application makes "dynamics" of an artwork explicit, and supports group interaction with simple messaging and "chat" facilities. This application may be used to facilitate learning and teaching of Art, but also as a research tool to investigate the learning of Art and also the development and dynamics of collaborating groups. Evaluation of a pilot study of the use of our system with a group of 20 school children is presented.
