OriginLab produces professional data analysis and graphing software for scientists and engineers. Our products are designed to be easy-to-use, yet have the power and versatility to provide for the most demanding user. Origin is an easy-to-use software application that provides powerful data analysis and publication-quality graphing capabilities tailored to the needs of scientists and engineers. Origin offers unique peak-analysis and curve-fitting capabilities, over 60 customizable graph types, and analysis templates, all within a tightly integrated workbook environment.
Peak Fitting
The Peak Analyzer tool in OriginPro provides the additional capability of finding and fitting multiple peaks in your spectra. Baseline anchor points can be customized and fit with a suitable fitting function, and the baseline fitting can be included as part of the final peak fitting process. A detailed Fit Control dialog is provided to control all aspects of peak fitting including mixed peak functions, peak centers and widths, sharing parameters, and imposing bounds and linear constraints on parameters. Graphical as well as tabular results are generated as part of the final fit report.
Surface Fitting
OriginPro can fit a 3D surface to XYZ data points. The surface and data points can be displayed together, including droplines from the points to the surface.
Statistics
OriginPro expands on the statistical analysis capabilities of Origin by providing additional tools for Descriptive Statistics, Discrete Frequency Counting, Normality Tests, Correlation Analysis, One-way and Two-way Repeated Measures ANOVA, Principal Component Analysis, Hierarchical Cluster and Discriminant Analysis, many Nonparametric Tests such as Friedman ANOVA and Two-Sample Kolmogorov-Smirnov Test and Mann-Whitney Test, Survival Analysis tools including Weibull Fit and Cox Proportional Hazard Model, ROC Curves, and Power and Sample Size Tests.
Signal Processing
Advanced signal processing features in OriginPro include Short-Time FFT (STFT), Hilbert Transform, Coherence, 2D FFT and 2D FFT-based Filtering, 2D Correlation, and Wavelet analysis.
Image Handling
OriginPro offers more ways to handle your image data, including alpha blending, pixel logic, morphological filtering, and interpolated background subtraction.
Analytical Power
With so much analytical power, OriginPro is the software of choice for those who want a single data analysis and graphing solution.

Does anyone have a copy of the 1954 version of Modern Timber Engineering? It's the only text I know of that has a section on lamella roof structures (resemble honeycombs). Any help would be greatly appreciated.
ABSTRACT
In order to determine the effectiveness of adding viscoelastic dampers to structures on the reduction of their seismic response, a comprehensive analytical and experimental program
was carried out. The experimental program was first conducted on a 2/5-scale five-story steel frame under precisely controlled ambient temperatures and subject to simulated ground motions with peak accelerations ranging from 0.12g to 0.60g. Results show that viscoelastic dampers are very effective in attenuating seismic structural response at all levels of earthquake ground motions, and that their energy dissipation capacity decreases as ambient temperature increases. However, they are effective at all temperatures tested in the research program. A rational seismic design procedure for viscoelastically damped structure is developed based on these results.
Further tests using a full-scale prototype structure confirm that damping in the full-scale structure can be significantly increased by adding relatively small viscoelastic dampers. The damper design procedure developed based on the scaled model can also be applied to the full-scale structure. This full-scale analytical and experimental study provides an important base for applying the extensive data generated from the scaled model testing to the full-scale structures.
------------------------
The protective and intelligent systems program constitutes one of the important areas of research
in the Building Project. Current tasks include the following:
1. Evaluate the performance of full-scale active bracing and active mass dampers already in place in terms of performance, power requirements, maintenance, reliability and cost.
2. Compare passive and active control strategies in. terms of structural type, degree of effectiveness, cost and long-term reliability.
3. Perform fundamental studies of hybrid control.
4. Develop and test hybrid control systems.
NCEER's activities in viscoelastic dampers research for seismic applications began in 1987 with analytical and experimental work carried out at the State University of New York at Buffalo and at the University of California at Berkeley. The ultimate aim is to determine their effectiveness when incorporated into a structure under seismic loads, and to develop a rational design procedure for such structures. This report summarizes results of a comprehensive analytical and experimental program for steel frame structures. The experimental program was first conducted on a 215-scale steel frame in the laboratory, followed by verification tests conducted on a full-scale prototype structure. A rational seismic design procedure for viscoelastically damped steel frame structures is developed based on these results.

Sorry, if this inquiry is too simplistic, but I have not been able to figure out how to view Posts for a particluar date.
For example, how do I search to view posts from November 01, 2011?
Thanks for your help.
