With the trend towards miniaturization and multi-functionality in products such as mobile electronic devices, miniature IC packaging such as fine pitch Ball Grid Array (BGA) package and Chip Size Package (CSP) are increasingly being used. However, the inherent vulnerability of these miniature IC packagings has brought along new reliability problems. Among them, the drop/impact robustness is the...

purpose: to evaluate the rate of optical coherence tomography (oct) grid decentration in a routine practice and its effect on thickness measurements methods: topcon spectral domain oct scans from various macular diseases including age related macular degeneration, diabetic macular edema, macular pucker and central serous chorioretinopathy (cscr) were studied in all patients visited during seven...

 In this paper, we attempt to find a solution to the problem of robot navigation in a domain with partial observability. The domain is a grid-world with intersecting corridors, where the agent learns an optimal policy for navigation by making use of a hierarchical memory-based learning algorithm. We define a hierarchy of levels over which the agent abstracts the learning process, as well as it...

grid computing is an emerging computing paradigm that will have significant impact on the next generation information infrastructure. due to the largeness and complexity of grid system, its quality of service, performance and reliability are difficult to model, analyze and evaluate. this paper proposes a virtual tree-structured model of the grid service. this model simplifies the physical struc...

To accurately simulate electric vehicle DC fast chargers' (DCFCs') harmonic emission, a small time step, i.e., typically smaller than 10 μs, is required owing to switching dynamics. However, in practice, harmonics should be continuously assessed with long duration, e.g., day. A trade-off between accuracy and efficiency thus exists. address this issue, multi-time scale modeling framework ...

the six-minute walk test (6mwt) is a well-tolerated test which reflects daily activities and can be easily used in clinical practice. the 6mwt provides information about functional capacity, response to therapy and prognosis across a range of chronic cardiopulmonary conditions. moreover, the 6mwt is sensitive to the common therapies used for chronic obstructive pulmonary disease, such as pulmon...
