This work investigates the application of bifurcation diagrams in the chaotic study of nonlinear RLC electrical circuits. The relevant second order differential equations were solved for ranges of appropriate parameters using Runge-Kutta approach. The solutions obtained were employed to produce bifurcation diagrams using Microsoft excel 2007. The mean estimate of 669 . 4   obtained from the b...

The French Lexicon Project involved the collection of lexical decision data for 38,840 French words and the same number of nonwords. It was directly inspired by the English Lexicon Project (Balota et al., 2007) and produced very comparable frequency and word length effects. The present article describes the methods used to collect the data, reports analyses on the word frequency and the word le...

In this paper, we present Tablexcel, a tabletop interface to Microsoft Excel. Single-user, desktop-based computer applications are pervasive in our daily lives and work. An application like Microsoft Excel, a widely deployed spreadsheet application, is used by a large number of businesses and users. Often, several users will collaborate on the creation of a spreadsheet, for example exchanging E...

The National Football league began in 1920 with 12 teams and has grown to 32 teams broken into 2 leagues and 8 divisions. In this time, a total of 14,657 games have been played [1]. Current scheduling requirements lead to a particular distribution of matchups, which when represented as an adjacency matrix should lead to a clustering representative of the league structure. In order to analyze th...

After appropriate pathologic confirmation of the diagnosis of melanoma of every sample, tumor samples were tested for BRAF V600E using a kit based on the PCR/hybridization method. DNA extraction was performed using the QIAamp DNA FFPE Tissue kit (Qiagen) following the manufacturer’s instructions. The BRAF mutation was detected using the ViennaLab BRAF StripAssay® kit (ViennaLab Diagnostics GmbH...

Methods: case-control study, with sample constituted of 273 children enrolled in Municipal Daycare Centers in Recife. It was researched the association of outcome with the variables related to socioeconomic characteristics, nutritive and not nutritious sucking habits and development of the stomatognathic system. We used the software STATA/SE 9.0 and Excel 2007 to calculate the risk measure, Odd...

著者ら [1]は,2011年の東日本大震災後に見られ た情報リテラシーにかかわる問題点を論じた際に, 公開されたデータの機械可読性の低さを指摘した。 それらのデータは,Excel に入力されていながら, 公開情報が PDF だけであったり,時にはデータ抽 出禁止の設定がなされていたり画像化されていたり して,集約や再解析にたいへん手間がかかった。 しかし,震災データに限らず,政府統計の総合窓 口 e-Stat [3] や自治体などで公開されているデータ を調べるにつれて,そもそも Excelへの入力の段階 でデータの再利用を考えず,罫線を多用した紙の帳 票作成を最終目的とするものが多いことに気づい た。こうしたデータは,PDFでなく Excelファイル (またはそれから生成した CSVファイル)で公開さ れたとしても,データを再解析するには余計な手間 がかかる。 こうした巧妙だがデー...

Spreadsheets, and MS Excel in particular, are established analysis tools. They offer an attractive user interface, provide an easy to use computational model, and offer substantial interactivity for what-if analysis. However, as opposed to RDBMS, spreadsheets do not provide a central repository hence they do not provide shareability of models built in Excel and lead to proliferation of multiple...

Survival curves are frequently used for reporting survival or mortality outcomes of experimental pharmacological/toxicological studies and of clinical trials. Microsoft Excel is a simple and widely used tool for creation of numerous types of graphic presentations however it is difficult to create step-wise survival curves in Excel. Considering the familiarity of clinicians and biomedical scient...

Some of the problems that rendered Excel 97, Excel 2000 and Excel 2002 unfit for use as a statistical package have been fixed in Excel 2003, though some have not. Additionally, in fixing some errors, Microsoft introduced other errors. Excel’s new and improved random number generator, at default, is supposed to produce uniform numbers on the interval (0,1); but it also produces negative numbers....
