INTRODUCTION Inspection in field conditions is labor intensive, demands great attention to details, subject to human errors and the reliability is limited. The interpretation of the data depends critically on the inspectors' experience, competence, attentiveness and meticulous dedication. For instance, rivet crack detection by eddy current is known to be a mundane and painstaking task, which ca...

-This research paper proposes the inspection system of heat pipe cooling for electronic devices, such as CPU in personal computer, laptop computer and so on. The inspection system is an essential part in production process of heat pipes CPU cooler. To ensure the high quality product, a 100% quality checking is taken into account. Generally, heat pipe inspection system is conducted by human ears...

Investigative and judicial errors along with expert mistakes are variation of errors in criminal trials. Often investigative and judicial mistakes are due to negligent attitude of investigators and trial to the requirements of the procedural form of the criminal procedure law, violation of the rights and legitimate interests of persons involved in the case. Of particular importance in eliminati...

ROSEN offers a combined inline inspection (ILI) service for Magnetic Flux Leakage (MFL) methodology and the Ultrasonic Testing (UT) with one inspection tool. These two methodologically independent measurements with one ILI run enable to supply a combined inspection service with many operational and qualitative benefits. The case study presented is based on a representative amount of high qualit...

This paper presents current and future uses of Differential Satellite Navigation Systems in Sierra Research’s Automatic Flight Inspection Systems (AFIS). The purpose of an Automatic Flight Inspection System is to inspect and calibrate ground-based aircraft navigation and landing aids. In Sierra’s inertial-based flight inspection system, a square root Kalman filter estimates the navigation error...

Inspection and maintenance errors that occur in aircraft maintenance systems have a formidable impact on the safety and reliability of air transportation. Evaluation of the aircraft maintenance system requires an analysis of the maintenance processes in use. The systematic evaluation of data collected on the aviation maintenance process can provide management with feedback on the performance of...

The use of synthetic focusing of torsional guided waves for detecting and sizing defects in pipes using an array of piezoelectric shear transducers clamped around the pipe circumference has been investigated. The performance of the focused system is tested and compared to an unfocused system using data from finite element simulations on pipes of different diameters with circumferential cracks; ...

Sarbanes–Oxley compliance requirements have forced firms to look at their use of spreadsheets in financial reporting. They are finding that they have many spreadsheets and that testing and other formal development disciplines are rare. The literature on spreadsheet errors has shown that without strong controls, most spreadsheets will have material errors; this means that firms that use uncontro...

In practice, manufacturing systems are never perfect and may have low quality outputs. Therefore, different decisions such as reprocessing, sale at lower prices or diminishing are made according to industry and market. This paper investigates the importance of supply chain coordination through developing two models in centralized decision-making for an imperfect quality manufacturing system wit...

− the present paper will present problems connected with accuracy inspection of free-form surfaces, performed with coordinate measuring machines equipped with touch measurement probes. The most important among them are, apart from the number and distribution of measurement points on a surface, errors caused by the probe radius compensation and determining the coordinate system. A theoretical an...
