Musicologists who study medieval music manuscripts were up until recently required to travel to the libraries and museums where these documents or their fragments are physically held. Increasingly however, digital image archives provide resources that allow scholars to conduct much of their research through both the inspection and manipulation of digital images. These images effectively serve as proxies...
This paper investigates the re-design and evaluation of an existing anchored discussion system. The purpose of the re-design is to focus social construction of knowledge on relevant information from online academic texts. We developed three prototype software environments: teacher-based attention guidance, peer-oriented attention guidance, and control condition. The evaluation of the re-design involved...
This research addresses the need to improve the accuracy of reliability analyses during the early stages of design. A failure modes and mechanisms taxonomy, similar to the hierarchical Functional Basis used in conceptual design, has been developed. In addition, a methodology is provided to classify failures. Current failure taxonomies lack a hierarchical structure, which results in a poor classification...
Multiple project environments are confronting a growing complexity with higher uncertainties and taut restrictions. A challenge in this research is problems and constraints of project risk management subject to sharing materials, equipments' allocation, skilled resources, and integrity information across concurrent multi-projects when project management is schedule-driven, often change requirements,...
The information and communication technologies (ICT) have the potential to improve the quality of life of individual with functional particularities, potentiating their activity in society, as well supplying the conditions for a prolonged active life, counter acting the natural age related lost of faculties. As such, the software component — of ICT — is lacking a good and attentive construction to...
One of the weaknesses in augmented reality (AR) scenes is that, most of the times, the virtual model lacks realism and is not integrated sufficiently into the scene to be credible. The problem lies in lighting conditions differences from real environment and virtual objects superimposed. This problem takes on special significance indoors, to visualize interior design proposals, because a non-integrated...
The aim of this research is to design and develop a software application to solve the problems that actually occur in the production and stock management processes of plastic molding injection. The application was developed using web pages that work together with a database. The user can check the current status of production process and stock inventory through a web browser of any Local Area Network...
Many firms that sell digital copies of copyrighted materials online face a common dilemma: the use of Digital Rights Management to impede pirates often also has negative implications for legitimate customers. We introduce a two-period model in which the use of DRM in the first period affects the probability of consumers encountering pirated copies in the second period, the threat of legal action affects...
Orthodontic braces are used to modify, malocclusions of teeth and jaws. Most of problems in dentistry can be investigated from a biomechanical point of view. Stress distribution in bracket, adhesive and tooth has been used as a criterion to determine bond strength of bracket- adhesive- tooth system. Tooth is consisted of three layers including enamel, dentin and pulp with three different mechanical...
Something about 1 million skeletal defects are reported each year, which are in need of bone-grafting to be cured. Note that population of the world is getting older and so the probability of bone fractures is increasing, while dealing with this would have lots of social and economical effects. Bone grafts can be both autologous and autogenous or as an alternative, be made of nonorganic materials...
It is observed that most of the projects managed by Information System (IS) graduates after their joining in industry get failed and these projects incur heavy amounts. It is because, the students during study take only a single course which is based on theory and few labs on Microsoft Office Project which is inadequate to make them capable of handling real world projects. After conducting a survey...
Parallel efficiency is always a fundamental research field in high performance computing. This paper focuses on parallel computing at high performance computing cluster with CASTEP program, discusses multi-core parallel efficiency in CASTEP, and analyses the influence of the main calculation parameters upon total CPU time and memory usage in case study, such as CPU cores(CPUs), cutoff energy, k-point,...
Consumer problems cannot be solved with old technologies. Most scalable, price-performance-enhancing solutions need advanced and emerging technologies that are creatively blended with the existing and rapidly evolving infrastructure. Technology is worth only if it is a significant multiplier of human effort, is able to deliver much better than average quality of manual effort, and addresses the chief...
The broad adoption of diagnostic and analytical techniques in the field of archaeology, presents a unique opportunity for e-Science in the form of scientific explanation, drawing from methodologies aimed at recording, archiving, analyzing, and disseminating, rich data collections. This paper presents a needed stepping stone towards cyber-archaeology, creating synergy between information technology...
The construction of a nuclear power plant is a very complex systematic project, mainly including engineering, procurement, construction and start-up phases. Among those stages, engineering materials management is a fundamental and decisive job. In this paper, the engineering materials' properties are researched. In order to manage the engineering materials in VPRM efficiently, we proposed the nuclear...
A novel technique has been developed under a Department of Homeland Security Small Business Innovative Research (SBIR) Program to exploit Video Games to dramatically improve the quality and availability of law enforcement and first responder training to locate and adjudicate nuclear sources. This training method is implemented in a software system which allows trainees to practice finding, identifying,...
Many Peer-to-Peer (P2P) networks have emerged as scalable platforms for enabling file-sharing and content-distribution applications. Due to their reliance on decentralized models encompassing millions of users, P2P networks are subjected to being infested with contraband material, copyright infringing content, as well as malicious viruses and programs. Moreover, the dynamics involved as users join...
Video surveillance systems are important part of today's organizations. When there is no live observation of the cameras image, it is important to have some alarm mechanisms for detection of physical impact against the cameras. Most simple video systems can detect motion and/or loss of video signal, but are vulnerable to covering or spraying the camera's lenses. Present study proposes a method for...
Despite intensive research for the improvement of the quality of II-VI crystals, until now no clear method permits to determine quickly the performance of final detector, directly on the as-grown crystal or on the wafers. This situation induces excess cost, which hinders the development of detectors based on these binary and ternary semiconductors.
The present study adopts acoustic means to investigate the articulatory problems from Shandong (Hereinafter, SD) learners on the production of English plosives. The VOT, pitch, and formants were selected as the parameters to examine the manner and place features of the plosives produced by the SD learners. Results demonstrate that the SD learners pronounce the voiced stops as voiceless ones. This...
