This paper describes time series properties of new value signal models (VSM), especially for second-order product-service-value systems (PSV-S). We have proposed a second-order PSV-S as a currency exchanger among different currencies, representing revenues, nonrecurring costs, recurring costs, as well as finance. We have also invented types of VSM, representing basic financial models of cash-flow...
Taiwanese memory packaging and testing factories include Powertech, ChipMOS, ASE, SPIL, Walton and FATC. The global three first tier giants, Samsung Electronics, Hynix and Micron, have predicted that the DRAM market in 2014 will be more stable. With the three-giant monopolization taking shape, the strategic alliance and corresponding excess profits of back-end packaging factories are expected to be...
With charging current increase, we will face battery stop charging issue easily with ID constrain. In order to solve potential thermal issues of battery charger station in early stage. Early and easy thermal assessment, which can now be completed in the stages before detailed routing, helps to alleviate potential problems by CFD. It is allowed us to understand the system temperature distribution which...
For the past 5 years, the National Library Board (NLB) has worked relentlessly to improve the search and find capability of its services, especially in the discovery of digital content. The pervasiveness of the Internet and the increasing use of mobile devices bring about a new demand for 24×7 access to library resources. This has given the NLB an impetus to digitise more materials and make them accessible...
The landscape of scholarly communication is constantly shifting. Library workers and researchers are always challenged to find useful and reliable sources of information to enrich collections and access to them by future scholars. Here citation analysis is applied to reference citations in two highly reputed journals in the area of planning and development to determine how scholarly research is being...
LED Solid state lighting will become increasingly more important in the future, and high performance is required more. And new material and process is quite important for LED flip chip and wafer level LED packaging. This paper show new Japan material quick views for LED flip chip & wafer level packaging. — New Japan material & process introduction for LED high power flip chip & wafer level...
The author played a role of the leader in a research project by the National Diet Library of Japan in 2012/2013, whose title is "Issues and Perspectives on Reference Services in Libraries of Japan." In that paper, he discussed the characteristics and "emerging trends" of reference services in the current context of public, academic, special, and national libraries, using the results...
The study focuses on development of digital library of Kashmiri handicraft "Papier-Machie". The art is one of the most famous and exported handicraft of Kashmir. The Greenstone Digital Library Software has been used to design digital library of "Paper-Machie" handicraft. The digital library will be a knowledge resource providing opportunities for storing, managing and retrieving...
ECGSIM is an interactive open source software package aimed at supporting ECG education and research. In this package, the user can change the local transmembrane potential interactively the resulting ECG changes are simulated and displayed instantaneously. In the previous versions of ECGSIM only a single heartbeat can be simulated, limiting its possibilities in inspecting changes in ECG morphology...
The goal of this study was to compare several ECG signal decomposition methods in order to enhance the accuracy of T wave end localisation. PTB Diagnostic ECG Database comprising 549 recordings was used. The idea was to combine the 8 independent leads (I, II, V1,…, V6) of the standard 12-leads ECG into a single lead.
Nowadays, Cardiovascular Magnetic Resonance (CMR) is gaining popularity in medical imaging and diagnosis. The acquisition of CMR images needs to be synchronized with the current cardiac phase to compensate the motion of the beating heart. The Electrocardiogram (ECG) signal can be used for such applications by detecting the QRS complex. However, the magnetic fields of the MR scanner contaminate the...
The thoracic impedance (TI) signal, which reflects fluctuations due to CCs and ventilations, has been suggested as a surrogate to compute CC-rate and ventilation-rate during cardiopulmonary resuscitation. This study developed a method based on empirical mode decomposition (EMD) to compute CC-rate and ventilation-rate using exclusively the TI. Twenty out-of-hospital cardiac arrest episodes containing...
The purpose of the present study was to evaluate the feasibility of blood pressure (BP) estimation by means of pulse arrival time (PAT) from data records of ICU patients available at the MIMIC public database. Datasets consisting of ECG, PPG and arterial BP waveforms from 8 subjects were used for the analysis and the relationship of PAT with systolic, diastolic and mean blood pressure was assessed...
Automatic question generation from text has been used and adapted to online and self-directed learning platforms. We incorporate methods into the automatic question generation process that are designed to improve question quality by aligning them to the specified pedagogical goals and to a learner's model. This is achieved by extracting, ranking and filtering relevant sentences in the given learning...
The research on ‘Pedagogical potentials of IEEE 802.11 WLAN to Nigerian based University’ is an in depth study to evaluate the potentials of its implementation to the entire teaching and tutoring vertical in Nigerian universities. While conducting this research study, the campus did not have the facility of Wireless internet service. Researchers are to provide the WLAN-Wireless local area network...
Advances in small scale fabrication processes have led to the advent of very thin flexible devices such as flexible RFID tags and smart clothing. In a geometrical sense, these present themselves as curved 2D open surfaces embedded in a 3D domain. When simulating EM behavior on these surfaces at low frequencies, a full 3D field model can become computationally expensive in terms of memory and run times...
Lossy conductors are not perfectly electric conductors and their finite conductivity needs to be carefully accounted for in the accurate solution of electromagnetic problems. Traditionally, surface integral equations (SIEs) are used to approximately describe the problems, but we use volume integral equations (VIEs) to exactly formulate the problems by treating the lossy conductors as dielectric-like...
Based on metamaterials and transformation optics theory, we develops a method to design 3D invisibility cloak with arbitrary shapes. The proposed electromagnetic invisibility cloak can perfectly hide the target object with arbitrary shapes and materials. Full-wave simulation results demonstrate that 3D electromagnetic invisibility cloaks designed by the proposed method have good performance for hiding...
Quasiconformal maps have been utilized for generating transformation optical devices with a range of applications including invisibility cloaks, waveguide benders, couplers, surface-conformal lenses and antennas. Here, we discuss their generation by numerically solving the Poisson's equation where the analytic solution of a typical electrostatic problem in the virtual space acts as a seed in numerically...
Tunability analysis based on electromagnetic modeling and simulation is performed for a miniaturized patch antenna loaded with self-biased magnetic films. The antenna includes a lossy dielectric substrate and layered thin-ferrite-film superstrate above microstrip. The structure is of multiscale and multimaterial feature and the system matrix may not be well-conditioned if the problem is described...
