brandtop.org -- Underwater Digital Camera Reviews Many people will be going to the nearest beach or river to cool down and rest when summer. In these conditions its nice to have camera that you dont have to worry about water splashing and maybe even get into the water. Many manufacturers have offered waterproof housings for compact cameras or DSLR cameras with the high cost. Underwater digital cameras have existed since 2002 and moving ahead along much the same lines as any others type of digital camera with faster processors. High and larger resolution sensors, built in image stabilizer, wider angle lenses and larger LCD screens. Even if you are not going swimming, a waterproof digital camera has benefit for everyone capturing in challenging situations. As the zoom ranges and the resolutions increase, waterproof digital cameras are not necessarily just a specialist tool and can be your one and only digital camera. In underwater digital camera reviews and test, we are going to compare at seven of waterproof digital cameras to see how they perform underwater.

RC ADVENTURES – Water “Break-In” Brushed RC Electric Motor – No need to “Waterproof”
GARAGE - www.RCSPARKS.com .................... FORUM - http ............... BLOG - RCSPARKS.com GALLERY - www.RCSPARKS.com RATE / COMMENT/ SUBSCRIBE! . Hey all, I did a quick tutorial on how to "get a little more" from your RC motor without having to spend any $$$! Please keep in mind that altering, or modifying electronics may cause injury or damage, so please do so at your own risk. Medic Media is not responsible if anything happens to your or your gear.. so please be careful when modding. This video is intended to show you how I would break in my BRUSHED motor. DO NOT ATTEMPT THIS BREAK IN METHOD WITH A "BRUSHLESS" SYSTEM! It will ruin your motors - Unless you are using an RC4WD Corefire waterproof Brushless system
Assessment of surface water quality using multivariate statistical techniques: A case study of the Fuji river basin, Japan

Description:
Multivariate statistical techniques, such as cluster analysis (CA), principal component analysis (PCA), factor analysis (FA) and discriminant analysis (DA), were applied for the evaluation of temporal/spatial variations and the interpretation of a large complex water quality data set of the Fuji river basin, generated during 8 years (1995-2002) monitoring of 12 parameters at 13 different sites (14@?976 observations). Hierarchical cluster analysis grouped 13 sampling sites into three clusters, i.e., relatively less polluted (LP), medium polluted (MP) and highly polluted (HP) sites, based on the similarity of water quality characteristics. Factor analysis/principal component analysis, applied to the data sets of the three different groups obtained from cluster analysis, resulted in five, five and three latent factors explaining 73.18, 77.61 and 65.39% of the total variance in water quality data sets of LP, MP and HP areas, respectively. The varifactors obtained from factor analysis indicate that the parameters responsible for water quality variations are mainly related to discharge and temperature (natural), organic pollution (point source: domestic wastewater) in relatively less polluted areas; organic pollution (point source: domestic wastewater) and nutrients (non-point sources: agriculture and orchard plantations) in medium polluted areas; and organic pollution and nutrients (point sources: domestic wastewater, wastewater treatment plants and industries) in highly polluted areas in the basin. Discriminant analysis gave the best results for both spatial and temporal analysis. It provided an important data reduction as it uses only six parameters (discharge, temperature, dissolved oxygen, biochemical oxygen demand, electrical conductivity and nitrate nitrogen), affording more than 85% correct assignations in temporal analysis, and seven parameters (discharge, temperature, biochemical oxygen demand, pH, electrical conductivity, nitrate nitrogen and ammonical nitrogen), affording more than 81% correct assignations in spatial analysis, of three different sampling sites of the basin. Therefore, DA allowed a reduction in the dimensionality of the large data set, delineating a few indicator parameters responsible for large variations in water quality. Thus, this study illustrates the usefulness of multivariate statistical techniques for analysis and interpretation of complex data sets, and in water quality assessment, identification of pollution sources/factors and understanding temporal/spatial variations in water quality for effective river water quality management.
