20120016523 | Slump Flow Monitoring - Method and system for monitoring slump flow of hydratable cementitious material such as wet concrete in a rotating mixing drum. Whereas prior art methods use a single value of the hydraulic pressure for turning the drum (such as the average value) and correlating with slump values using the vertical drop measurements of the standard slump test (e.g. ASTM C 143-05), the present invention involves analysis of values corresponding to slump flow of concrete samples, preferably having slump flow values of 16-36 inches when measured using standard slump flow tests (e.g., ASTM C1611-05). | 01-19-2012 |

20140156609 | DATABASE TABLE COMPRESSION - Embodiments relate to table compression in a database. The database is organized in tables including rows and columns An aspect includes defining a range partition of a table of the database according to a first attribute of the table. Internal ranges of the table of the database are defined according to a second attribute of the table. A target internal range of the internal ranges is determined to insert a row as a new entry into the table. A determination is made as to whether an internal range compression directory exists for the target internal range. Based on determining that no internal range compression directory exists for the target internal range and a predefined threshold value of a number of rows is exceeded in the target internal range, the internal range compression directory for the target internal range is created. | 06-05-2014 |
