20140257742 | METHOD TO STRUCTURE MINERAL AGGREGATE GRADATION BY USING THREE CONTROL POINTS AND TWO CURVES - The invention involves “a method to structure mineral aggregate gradation by using three control points & two curves”, including the following steps: (1) Three control points are determined according to the property of the mixtures: nominal maximum size of aggregate and its passing rate, nominal minimum size of aggregate and its passing rate, and the discontinuity point between the coarse aggregate and the fine aggregate and its passing rate. (2) The grading curves of the coarse and the fine aggregate are selected respectively with Power function model, Exponential function model and Logarithmic function model. (3) Measure the stamped density and the stamped voids in mineral aggregate, and then choose the grading of the coarse and the fine aggregate on the basis of the project need. The invention can help constitute different gradation curves in line with local materials from different areas and sources. In this way can the mineral aggregate's property give the full play to the mixtures, and it's a good guide to the mix proportion of the asphalt mixture. | 09-11-2014 |

20130007007 | METHOD AND APPARATUS FOR PROVIDING A LIST-BASED INTERFACE TO KEY-VALUE STORES - An approach is provided for providing a list-based interface to key-value stores. The library interface platform determines one or more key-value pairs of at least one key-value store, the one or more key-value pairs comprising one or more data entries. Next, the library interface platform causes, at least in part, an association of at least one list object with the one or more key-value pairs, one or more sub-list objects, or a combination thereof. Then, the library interface platform provides at least one interface for performing one or more operations on the at least one list object to interact with the one or more data entries, the one or more key-value pairs, the one or more sub-list objects, or a combination thereof. | 01-03-2013 |
20130103729 | METHOD AND APPARATUS FOR PROVIDING A KEY-VALUE BASED STORAGE INTERFACE - An approach is provided for implementing a virtual file system using a key-value-based storage interface. A key-value directory framework determines one or more files stored in at least one stream-based file store. The key-value directory framework causes, at least in part, a grouping of the one or more files into at least one key-value directory. The key-value directory includes, at least in part, one or more key-value pairs of a distributed key-value store. The key-value directory framework also causes, at least in part, a storage of (a) at least one identifier of the one or more files, the at least one key-value directory, or a combination thereof as one or more keys of the one or more key-value pairs; (b) block-based access information associated with the one or more files as one or more values of the key-value pairs; and (c) a locking mechanism to facilitate coordination of threads across multiple hosts. | 04-25-2013 |
