Methodology for the development of in-line optical surface measuring instruments with a case study for additive surface finishing

AbstractObjective:To demonstrate the use of an optical surface scanner, with associated software, in the assessment of rhinoplasty patients, and to discuss the possible clinical applications of this technology in the future.Design:Case study analysis of pre- and post-operative scans of a patient undergoing septorhinoplasty at Whipps Cross University Hospital, London, UK.Subject:A 21-year-old man undergoing septorhinoplasty underwent pre-operative optical surface scanning of his face. The scans were repeated at one week and one year post-operatively. Software developed at University College London was then used to analyse the scans.Results:The scans clearly showed that the man's dorsal hump had been well reduced and the nose straightened, with a resulting 1600 mm3 gain on the right side and a 1000 mm3 loss on the left side of the nose. Tip projection had also been achieved.Conclusion:This technique allowed objective quantification of facial features and analysis of change. It may well prove useful in the future in predicting change following surgical intervention.

The aim of this study was to analyze the level of satisfaction in three municipal sports centers in the city of Malaga and to learn and analyze the characteristics of users older than 40 years of age in these centers. A total of 303 persons (123 men and 180 women) from three sports centers in the city of Malaga participated in this study (M = 58.14, SD = 7.16 years). The Evaluation of Perceived Quality in Sports Services test (CECASDEP) was used, and the results demonstrated that the different dimensions studied—sports center, activity space, locker rooms, program of activities, and trainer—were very positively correlated. The level of customer loyalty increased with user satisfaction and perceived quality of services as well as the age of the person. Users were also found to be more motivated to take part in physical activities due to greater satisfaction. The highest scores were given to the trainers, who played a key role in all three sports centers. In conclusion, we gathered important insights into perceived quality in different sports centers. This information can be used by sports managers to strengthen dimensions with lower scores and improve those with higher scores. In addition, the study confirms that the level of customer loyalty is related to the perceived quality scores. Therefore, the use of measuring instruments is recommended to optimize the quality of sports services.

The educational orientations of 1,331 internal and external students and 154 staff at the University of New England were investigated using two recently developed U.S. measuring instruments. Significant differences between the views of staff and students were found in the areas of assessment, the role of students in decision-making, and (in the case of the internals) the vocational relevance of courses and the importance of learning for its own sake. The views of the teaching staff more closely corresponded to those of the external rather than internal students. The importance of these findings is discussed in the context of the desirability for our tertiary institutions to adapt to the possibly changing needs of their student bodies.

Vickers Hardness Test

A calibration is an activity to determine the conventional validity of the appointment value of measuring instruments and measuring materials by comparing them to standard measurements that are traceable to national and international standards for measurement units and or international and certified reference materials. The calibration is generally a process of adjusting the output or indication of a measurement device to match the magnitude of the standard used in certain accuracy. The purpose of this paper is to find out the vickers hardness test calibration whether the machine running normally or there is a problem with the device. A case study was conducted in PT. Tenaris SPIJ, Cilegon, Indonesia. A vickers hardness testing in the case study has its own reference standard, namely ISO 6507-2: 2018 Metal material - Hardness Test Verification and Calibration of the test machine. The vickers hardness test equipment is a machine to conduct tests using a diamond pyramid with a plane angle of 136°, by means of an emphasis by an indentor that results in a trace or indentation on the surface of the test object. The vickers hardness testing is abbreviated as HV or HVN and also known as Diamond Pyramid Hardness Test (DPH). Result of calibration in the case study was found the repeatability value on vickers hardness testing machine of 32 HV 10 and the error value of ±3%.
