Limits of accuracy

  • Defining the limits of accuracy for all measuring instruments. The limits of measurement must be better than the required limits for the product, process and safety. If the measuring instrument fails to meet calibration limits then the product, process or safety could have been compromised. If a factor of two is set, and if the measuring instrument fails calibration there is a margin allowed before any quality issues are raised. The factor should be as large as possible, the larger the factor the greater the safety margin.

  • We compare the effectiveness of two related • machine translation models applied to the same limited-domain task. One is a transfer model with monolingual head automata for analysis and generation; the other is a direct transduction model based on bilingual head transducers. We conclude that the head transducer model is more effective according to measures of accuracy, computational requirements, model size, and development effort.

  • The current study contributes exploratory findings to the body of knowledge on L2 writing by investigating task complexity embedded in different task types. The use of discourse measurement of accuracy and complexity revealed some IELTS candidates’ language problems related to genre writing. The gained knowledge may help teachers manipulate task features to channel learners’ attention to the area in which they fail.

  • Digital Elevation Model (DEM) is an important component of GIS applications in many socio-economic areas. Especially, DEM has a very important role in monitoring and managing natural resources, preventing natural hazards, and supporting spatial decision making. Usually, DEM is built by interpolation from a limited set of sample points. Thus, the accuracy of the DEM is depended on the used interpolation method.

  • The most fundamental issue connected to credit scoring is the level of accuracy of the information that forms the basis for the scores. Regardless of whether lending and pricing decisions are made by a manual or automated review of a consumer’ s credit, the potential for inaccuracies in credit reports to result in loan denials or higher borrowing costs is a cause for concern. Several organizations have conducted studies and surveys to quantify the pervasiveness of credit report errors, with widely ranging findings regarding how many credit reports contain errors (from 0.

  • While OOV is always a problem for most languages in ASR, in the Chinese case the problem can be avoided by utilizing character n-grams and moderate performances can be obtained. However, character ngram has its own limitation and proper addition of new words can increase the ASR performance. Here we propose a discriminative lexicon adaptation approach for improved character accuracy, which not only adds new words but also deletes some words from the current lexicon.

  • This paper presents an improved method based on the jacobian matrix and the error feedback. By using this method, the accuracy of the solution of inverse kinematics for the vehicle-manipulator system is improved. In addition, one of the advantages of a redundant system is exploited to avoid impact on joint limitations. Numerical simulations in software Matlab are carried out to verify the efficiencies of the proposed method.

  • Only basic selection parameters are included. To make the very best selection of a ball screw, the designer should specify such critical parameters as the load profile, the linear or rotational speed, the rates of acceleration and deceleration, the cycle rate, the environment, the required life, the lead accuracy, the stiffness, and any other special requirement. If in doubt, please consult an SKF ball screw specialist before placing an order.

  • Sensors used for ultra-precision machines include position and velocity sensors, which are mostly part of a control loop, and for some special applications acceleration sensors for active vibration control, and thermal sensors for thermal error compensation [1]. An essential component of each positional feedback loop in a machine tool is the displacement measurement system for detecting the actual position of moving machine parts. It is the performance of such measurement systems that limits the accuracy of machine tools and hence directly affects the quality of the machined part...

  • Since a secondary coolant cannot be used below its freezing point, certain ones are not applicable at the lower temperatures. Sodium chloride's eutectic freezing point of -2O0C limits its use to approximately -120C. The eutectic freezing point of calcium chloride is -530C, but achieving this limit requires such an accuracy of mixture that -4O0C is a practical low limit of usage. Water solubility in any open or semi-open system can be important. The dilution of a salt or glycol brine, or of alcohol by entering moisture, merely necessitates strengthening of the brine. ...

  • MM, Inc. strongly discourages the storage of large numbers of e-mail messages for a number of reasons. First, because e-mail messages frequently contain company confidential information, it is good to limit the number of such messages to protect the company’s information. Second, retention of messages fills up large amounts of storage space on the e-mail server and personal hard disks, and can slow down the performance of both the network and individual personal computers.
