The purpose of this study was to ensure the reliability and accuracy of the computer generated data by comparing it to human generated data regarding painful sites, and to account for all factors that may impinge on the accuracy of computer generated data. Analysis of painful site data by multiple independent observers will likely resolve this discrepancy. The researchers were blinded to the computer generated data as they coded the data following guidelines that defined 1) the method for counting the number of pain sites in each drawing, 2) an ordering hierarchy for assigning a site number to each site, and 3) whether or not a particular body segment was included in each site. A systematic review on the subject found a sensitivity of 76% (95% CI, 54% to 89%) and a specificity of 88% (95% CI, 67% to 96%) for the correct interpretation of acute cardiac ischemia by a computer algorithm. Computer-assisted stereolithographically guided surgery allows an ideal implant placement for prosthetic restoration. However, a significant difference between the computer and the researcher was found for inclusion of the lower back segment – 0.1 +/- 0.2 and 0.5 +/- 0.5 of painful sites, respectively (P < 10-3). Material and methods. Computer speed is measured in units of millisecond (one thousandth of a second), microsecond (one millionth of a second), nanosecond (one billionth of a second) , and picosecond (one trillionth of a second). One example is the PE Analogue Computer, published in Practical Electronics in the September 1978 edition. Accuracy of computer aided implant placement 1. 1. The accuracy with which the computer output reflected the anaesthetic technique was found to be 52% in the retrospective survey and 33% in the prospective survey. Therefore one has to be very careful in making sure that the signal is 'clean' as possible by: Different manufacturers of ECG equipment have produced different algorithms for ECG interpretation. Information Accuracy relates to “the correctness of the output information” (Bailey & Pearson, 1983).It is one of the elements of intrinsic data quality (Wang & Strong, 1996). The purpose of this in vivo retrospective study was to evaluate the accuracy of a computer-designed stereolithographic surgical guide. The accuracy of the protocol was determined by comparing planned movements of the jaws with the actual surgical movements, analysing frontal and lateral cephalometries. Therefore, the established algorithms within the computer program, which convert a graphic pain representation into a numerical description of the number of painful sites and their anatomic distribution, must be able to account for this variability. I know that 10 years ago, typical clock precision equaled a system-tick, which was in the range of 10-30ms. There was strong accuracy in the interpretation of site number and locations between the researcher's data and the computer-generated data. It processes data according to the sequence of instructions . Not surprisingly, the accuracy of algorithms therefore differs. Pre- and postoperative computed tomography images were compared using specific software. The study, published in Nature Biotechnology, developed open-source software that can be used to judge the accuracy of computer predictions and establish this benchmark. In measurement of a set, accuracy is closeness of the measurements to a specific value, while precision is the closeness of the measurements to each other. [1] However, this study was performed in 1991 and algorithms have developed since. A third researcher and consensus discussion resolved coding discrepancies between researchers. It does 2 things, it does arithmetic problems which are 100% accurate. 6), 2012, 112–123 AAMIR ZAHID GODIL FIRST YEAR P.G. However, due to the moderate heterogeneity found among the studies included in this meta-analysis, a pragmatic recommendation about the use of computer-assisted analysis is not possible. Significant differences for all deviation parameters was found for implant-guided placement compared to placement without guidance. Over the past years, precision was increased in multiple steps. 8,9,11,15,17,20–23 PY - 2018/5/1.

Some 'self learning' algorithms have been developed that improve themselves by learning from adjustments that cardiologists make to their diagnosis. Dictionary ! An important part of any satellite reception operations is accurate time keeping. 9 Several reviews of scientific literature have been performed to survey the accuracy of computer-guided implantation with stereolithographic surgical templates. Meta analysis revealed a mean error of 0.99 mm (ranging from 0 to 6.5 mm) at the entry point and of 1.24 mm (ranging from 0 to 6.9 mm) at the apex. In multisegmental transfer with condylar involvement, computer-assisted fixation is recommended to ensure accuracy of the preoperative plan. The accuracy of computer-assisted primary mandibular reconstruction with vascularized bone flaps: iliac crest bone flap versus osteomyocutaneous fibula flap. This can be challenging if subtle ST segment shifts are present, and ST segment shifts can also be present in healthy persons. Computer-guided flapless implant (CGFI) surgery is well established for patients who are fully edentulous (mucosa-supported guides), 18–22 and it shows higher accuracy when compared with freehanded implant placement. The authors conclude that reliance on computer interpretation would result in inappropriate underuse of thromobolytic therapy. For example, if you know that you have a mass standard that is 50.00 grams, and you measure it to be 49.98 grams, then your measurement is very accurate. Notwithstanding being quick, Computers are additionally precise. PAINReportIt® is a computer based, self-reporting pain assessment tool that was designed to serve as a communication tool between patients and medical care providers. For example, patients reported a mean value of 3.9 (+/- 3.3) and 3.8 (+/- 3.5) painful sites according to the computer program and researcher, respectively. Computer is an electronic device which is used to store the data, as per given instructions it gives results quickly and accurately. Computer-assisted surgery provides cutting guides for obtaining accurate fibular segments, but current fixation methods lead to inaccuracies and reproducibility errors. 11 CPR data collected at the point of care are being used increasingly for these purposes as well as being used for making administrative and policy decisions.
