The task of compressed sensing is to recover a sparse vector from a small number of linear and non-adaptive measurements, and the problem of finding a suitable measurement matrix is very important in this field. While most recent works focused on random matrices with entries drawn independently from certain probability distributions, in this paper we show that a partial random symmetric Bernoulli...
Version information plays an important role in spreadsheet understanding, maintaining and quality improving. However, end users rarely use version control tools to document spreadsheets' version information. Thus, the spreadsheets' version information is missing, and different versions of a spreadsheet coexist as individual and similar spreadsheets. Existing approaches try to recover spreadsheet version...
Like most conventional software, spreadsheets are subject to software evolution. However, spreadsheet evolution is rarely assisted by version management tools. As a result, the version information across evolved spreadsheets is often missing or highly fragmented. This makes it difficult for users to notice the evolution issues arising from their spreadsheets. In this paper, we propose a semi-automated...
The trend of Chinese processing trade transformation from east to the central and western regions has been formed. Facing the fierce competition from other Midwest provinces, wuhan city circle should take their own advantages, find the influential undertake processing trade transfer of related factors, accelerate the development of logistics, perfect bonded logistics functions, expand use of investment...
This The equipment and experimental conditions which prepared diamond films by hot cathode DC-PCVD were introduced in this paper. The surface morphology of diamond film samples are discussed when the Methane flow rates was 2sccm, 4sccm, 6sccm and 8scc, the Ethanol flow rates was 50sccm, 60sccm, 70sccm and 100sccm, the Methanol flow rates was 2sccm, 6sccm and 10sccm, the substrate temperature was 1000...
In order to study the effect of the thickness of DPVBi on the performance of WOLED, we constructed multilayer organic electroluminescent devices, the structure is ITO/2T-NATA (20 nm) / NPBX (15 nm) / DPVBi (x nm) / Rubrene (0.5 nm) / DPVBi (x nm) / Rubrene (0.5nm) / Alq3 (40 nm) / LiF (0.5 nm) / Al. Such structure takes full advantage of the hole blocking and luminous properties of DPVBi, and it is...
