Research Infrastructures (RIs) are considered to be tools for science and operate in the form of facilities, resources and services. They promote technological development and provide an accelerator for the advancement of knowledge by offering unique research services to all interested users and stakeholders to enable top-level research in all possible scientific disciplines: from social scienc...
Modeling for operation rules is essential function requirement in equipment simulation training system based on VR. Aiming at the modeling actuality of present equipment operation rules, which has no systematic, no generality and no formatting expression, layered modeling system framework based on federation is brought forward referencing to the “Federation and Member” concept of HLA. Open mode...
Due to the vision-impaired users commonly having difficulty with mobile-phone function operations and adaption any manufacturer's user interface design, the goals for this research are established for evaluating how to improve for them the function operation convenience and user interfaces of either mobile phones or electronic appliances in the market currently. After applying collecting back 3...
We address the problem of rate scaling of multiple layered video streams in applications such as a multi-camera video surveillance system. This differs from the single video streaming scenario in that relevant information from all sources has to be aggregated and a collective decision made. We propose a scenario to achieve better granularity in quality adaptation by considering inter-source and...
The use of flight simulation tools to reduce the schedule, risk, and required amount of flight-testing for complex aerospace systems is a well-recognized benefit of these approaches. However, some special challenges arise when one attempts to obtain these benefits for the development and operation of a research Uninhabited Aerial Vehicle (UAV) system. Research UAV systems are characterized by t...
A cost efficient process is the goal of every part of the wood processing chain. It is directly related to a yield that is gained out of a raw material. On the other hand these processes have to deliver a certain product quality in order to satisfy customer needs. Very often a tradeoff has to be made between the yield and the product quality through optimization processes. The main objective of...
In this research, robotic cell scheduling problem with three CNC machines and with an operation on each machine with the purpose of optimizing manufacturing cost and time in S1 cycle has been investigated. To obtain the optimal total cost of production has been used the optimal processing time on machine operation. In this research, robotic cell scheduling is studied in three different situatio...
Because of the digit limitation of floating point, significant inaccuracy often occurs during the process of mathematical calculation, which may lead to catastrophic loss. Normally, people believe that adjustment of floating-point precision is an effective way to solve this problem, since high-precision floating-point number has more digits to store information. Thus, it is a prevalent method t...
Every research study requires a sound design, careful planning, good management and proper analysis. In some cases, a study is conducted in multiple sites and possibly in different countries, often in order to increase the study sample size or to compare and contrast different study populations. Multi-center studies require co-investigators and research staff not only knowledgeable about the st...
