Indexed file system and a method and a mechanism for accessing data records from such a system

A computer filing system includes a data access and allocation mechanism including a directory and a plurality of indexed data files or hash tables. The directory is preferably a radix tree including directory entries which contain pointers to respective ones of the hash tables. Using a plurality of hash tables avoids the whole database ever having to be re-hashed all at once. If a hash table exceeds a preset maximum size as data is added, it is replaced by two hash tables and the directory is updated to include two separate directory entries each containing a pointer to one of the new hash tables. The directory is locally extensible such that new levels are added to the directory only where necessary to distinguish between the hash tables. Local extensibility prevents unnecessary expansion of the size of the directory while also allowing the size of the hash tables to be controlled. This allows optimisation of the data access mechanism such that an optimal combination of directory-look-up and hashing processes is used. Additionally, if the number of keys mapped to an indexed data file is less than a threshold number (corresponding to the number of entries which can be held in a reasonable index), the index for the data file is built with a one-to-one relationship between keys and index entries such that each index entry identifies a data block holding data for only one key. This avoids the overhead of the collision detection of hashing when it ceases to be useful.

High-strength hot-rolled steel sheet having excellent stretch flangeability, and method of producing the same

The invention provides a thin high-strength hot-rolled steel sheet with a thickness of not more than 3.5 mm which has excellent stretch flangeability and high uniformity in both shape and mechanical properties of the steel sheet, as well as a method of producing the hot-rolled steel sheet. A slab containing C: 0.05-0.30 wt %, Si: 0.03-1.0 wt %, Mn: 1.5-3.5 wt %, P: not more than 0.02 wt %, S: not more than 0.005 wt %, Al: not more than 0.150 wt %, N: not more than 0.0200 wt %, and one or two of Nb: 0.003-0.20 wt % and Ti: 0.005-0.20 wt % is heated at a temperature of not higher than 1200° C. The slab is hot-rolled at a finish rolling end temperature of not lower than 800° C., preferably at a finish rolling start temperature of 950-1050° C. A hot-rolled sheet is started to be cooled within two seconds after the end of the rolling, and then continuously cooled down to a coiling temperature at a cooling rate of 20-150° C./sec. The hot-rolled sheet is coiled at a temperature of 300-550° C., preferably in excess of 400° C. A fine bainite structure is obtained in which the mean grain size is not greater than 3.0 mum, the aspect ratio is not more than 1.5, and preferably the maximum size of the major axis is not greater than 10 mum.

Method to display and manage computer pop-up controls

This invention enhances the usability of the human-computer interface by disclosing a technique for the display of single and multi-generation pop-up controls at a location that best meets the user's criterion of an optimal display location. The technique determines the minimum size of a rectangle capable of displaying the actual or likely maximum size of pop-up controls requested during any given activation of the subsystem that manages display of requested controls. The invention then identifies a location that assures the said rectangle either has no overlay or a minimum overlay of the screen area of current interest to the user while avoiding display clipping. A fixed-point is now determined within said rectangle based on physical characteristics of the controls to be displayed that permits display of descendant controls in a backward cascade that enables the user to maintain visual focus at a fixed screen location while manipulating successive controls. The invention provides the user with the ability to redisplay any previously displayed control irrespective of control type as well as provide a "Done" capability for appropriately designed controls that permits the user to convert a single selection control into a multi-selection control. As an adjunct to the reverse order the invention provides four capabilities that permit the user to undo and redo arbitrary services via performed via redisplay of ancestor controls.

External system integration into automated attribute discovery

Methods and apparatus to transform attribute data about assets in a source system data model into attribute data about the same assets in a target system data model. The first step is to extract the necessary attribute data from attribute data collected about inventory assets of a business entity needed to populate the attributes in objects representing those inventory assets in a target system data model. Transformation rules are written which are designed to make all conversions necessary in semantics, units of measure, etc. to transform the source system attribute data into attribute data for the target system which has the proper data format. These transformation rules are executed on a computer on the extracted attribute data and the transformed attribute data is stored in an ER model. In the preferred embodiment, the transformation rules are object-oriented in that transformation rules for subtypes can be inherited from their parent types or classes. An export adapter which is capable of invoking the application programmatic interface of the target system CMDB is then used to export the transformed attribute data stored in the ER model to the target system CMDB. A heuristic method to create self-consistent data blocks without exceeding a maximum size limit involves loading instances of entity types and all related instances in the order of decreasing connectivity metric.

Transmission frame structure for control communication network of distributed control system for nuclear power plant

A transmission frame structure for use in a control communication network allows all process control stations contained in the control communication network to share monitoring / control information received from a field communication network or an information communication network, and properly copes with faulty operations of channels (i.e., ring-shaped lines) or process control stations for use in the control communication network. The transmission frame structure of a control communication network for use in a nuclear-power-plant distributed control system which broadcasts data received from a node having transmission authority to all nodes via a bypass line, and allows a ring accelerator to detour the data and to isolate an erroneous station from normal stations, includes a transmission frame. The transmission frame includes: a destination address for performing the broadcasting operation; a source address for recording a source node address (ID) therein; a type / length field for classifying frames into a control data frame and a network management event frame; a network management (NM_TYPE) field which is valid only when it is designated by type / length field, and performs different roles according to network management event frame types; a Seq&Ver field for including the number of transmissions of a data frame and frame upgrade version information; a NS_ID field for recording number information of a node equal to the next token reception node, and being used when one station transmits a token to the next station; a data field having a predetermined maximum size of 1 kbyte, for including not only general control information according to a value of the type / length field, but also 7 event frames such as a token frame; and a CRC (Cyclic Redundancy Code) field for inspecting the presence or absence of a CRC error, whereby the transmission frame operates the communication network, solves a malfunction or error of the communication network, and recovers the communication network.
