Is a computer-based measurement method superior to a recommended manual method by the ROHO®Group to assess pressure in the sitting position?

Precise analysis of occlusal contacts and occlusal force is a problem in functional diagnostics that has not yet been satisfactorily resolved, despite the fact that the deleterious consequences of an unbalanced occlusion are widespread, and can be severe. In clinical practice, the present-day analysis of the occlusion is reduced to depicting force with color-marking foils that leave ink marks upon the teeth. However, these foils only indicate the localization of contacts, but do not describe reliably the occlusal force relationships. Precise analysis that incorporates time resolution, and plots the distribution of forces within the occlusion, is not possible when employing the traditional occlusal indicator methods. A detailed occlusal force and timing analysis can only be provided by performing a computer-assisted analysis, using the T-Scan III system (Tekscan, Inc. S. Boston, MA, USA), which records changing relative occlusal force levels and real-time occlusal contact sequence data, with high definition (HD) recording sensors. The following chapter demonstrates the accuracy and reliability of this computer-based occlusal measurement method that reliably describes the time-dependent distribution of occlusal force evolution.

In a companion paper results obtained from computer simulation1 have demonstrated that the sound propagation characteristics of disproportionate rooms are determined by the product of the fitting parameters scattering cross-section (Q) and absorption coefficient (αobst) of fittings. It was also proposed that the absorption of a fitting as measured in a conventional reverberation chamber is equivalent to four times the product of those two parameters. This suggests that measurement of fitting absorption in a conventional reverberation chamber could provide the data required for input into current computer based factory noise prediction models. Since both parameters are required as inputs to computer models it would be necessary to separate them in some way from the data obtained in the reverberation chamber. In this paper two methods for determining the scattering parameters of fittings in industrial buildings based upon acoustical measurements are described. The accuracy of these is compared with that resulting from the application of a geometrical measurement method to determine the scattering cross-section (Q) of various shapes of model scatterers employed in experimental work employing 1:20 acoustic scale models. The values of Q obtained from each method were used to predict sound characteristics a model disproportionate chamber using RAYSCAT. The predicted results obtained from the computer model by inputting the values of Q determined using the acoustical measurement methods were found to be more accurate than those using the geometrical measurement method.

Everyday Design

Some structural components of bridges can be idealized as cantilever slabs in isolation, for the purpose of analysis. Usually a realistic analysis of such components, when subjected to concentrated loads, is done by methods that are either computer-based or too complex for everyday design application. A semi-graphical manual method for the analysis of semi-infinite cantilever slabs is presented as an alternative to rigorous solutions.The method presented supplements an earlier published manual method for the analysis of infinitely wide cantilever slabs.

Matching Techniques

Potteries are the most numerous finds found in archaeological excavations; they are often used to get information about the history, economy, and art of a site. Archaeologists rarely find complete vases but, generally, damaged and in fragments, often mixed with other pottery groups. By using the traditional manual method, the analysis and reconstruction of sherds are performed by a skilled operator. Reviewed papers provided evidence that the traditional method is not reproducible, not repeatable, time-consuming and its results have great uncertainties. To overcome the aforementioned limits, in the last years, researchers have made efforts to develop computer-based methods for archaeological ceramic sherds analysis, aimed at their reconstruction. To contribute to this field of study, in this paper, a comprehensive analysis of the most important available publications until the end of 2019 is presented. This study, focused on pottery fragments only, is performed by collecting papers in English by the Scopus database using the following keywords: “computer methods in archaeology", "3D archaeology", "3D reconstruction", "automatic feature recognition and reconstruction", "restoration of pottery shape relics”. The list is completed by additional references found through the reading of selected papers. The 53 selected papers are divided into three periods of time. According to a detailed review of the performed studies, the key elements of each analyzed method are listed based on data acquisition tools, features extracted, classification processes, and matching techniques. Finally, to overcome the actual gaps some recommendations for future researches are proposed.Highlights:<ul><li>The traditional manual method for reassembling sherds is very time-consuming and costly; it also requires a great deal effort from skilled archaeologists in repetitive and routine activities.</li><li>Computer-based methods for archaeological ceramic sherds reconstruction can help archaeologists in the above-mentioned repetitive and routine activities.</li><li>In this paper, the state-of-the-art computer-based methods for archaeological ceramic sherds reconstruction are reviewed, and some recommendations for future researches are proposed.</li></ul>

The main objective of developing this system is to automate the process of providing attendance to the students who are a part of the event. Here, the student’s work gets easier. There is no more wandering for permissions. This system follows the college rules and it is more reliable. Student can view his details. He can track his permission details. He can also view at any point of time. This would reduce the present pen and paper based manual method of taking attendance. Replacing the old traditional method, this system will reduce the use of piles of paper and hardcopies. It will save time, reduces the amount of manual work done by students and teachers. This is replaced by a computer based system developed using Servicenow. Students fill their details in the form by logging into the portal and some validations are done while filling the form using client scripts and ui policies. Here all the process is automated using workflows. Event managers, Head of the Department and Class Incharge analyse the students details which are maintained in the system. Thus, faculty provide attendance.

Triage Time

AbstractIntroductionMass-casualty incidents (MCIs) easily overwhelm a health care facility’s human and material resources through the extraordinary influx of casualties. Efficient and accurate triage of incoming casualties is a critical step in the hospital disaster response.Hypothesis/ProblemTraditionally, triage during MCIs has been manually performed using paper cards. This study investigated the use of electronic Simple Triage and Rapid Treatment (START) triage as compared to the manual method.MethodsThis observational, crossover study was performed during a live MCI simulation at an urban, Canadian, Level 1 trauma center on May 26, 2016. Health care providers (two medical doctors [MDs], two paramedics [PMs], and two registered nurses [RNs]) each triaged a total of 30 simulated patients - 15 by manual (paper-based) and 15 by electronic (computer-based) START triage. Accuracy of triage categories and time of triage were analyzed. Post-simulation, patients and participating health care providers also completed a feedback form.ResultsThere was no difference in accuracy of triage between the electronic and manual methods overall, 83% and 80% (P=1.0), between providers or between triage categories. On average, triage time using the manual method was estimated to be 8.4 seconds faster (P<.001) for PMs; and while small differences in triage times were observed for MDs and RNs, they were not significant. Data from the participant feedback survey showed that the electronic method was preferred by most health care providers. Patients had no preference for either method. However, patients perceived the computer-based method as “less personal” than the manual triage method, but they also perceived the former as “better organized.”ConclusionHospital-based electronic START triage had the same accuracy as hospital-based manual START triage, regardless of triage provider type or acuity of patient presentations. Time of triage results suggest that speed may be related to provider familiarity with a modality rather than the modality itself. Finally, according to patient and provider perceptions, electronic triage is a feasible modality for hospital triage of mass casualties. Further studies are required to assess the performance of electronic hospital triage, in the context of a rapid surge of patients, and should consider additional efficiencies built in to electronic triage systems. This study presents a framework for assessing the accuracy, triage time, and feasibility of digital technologies in live simulation training or actual MCIs.BolducC, MaghrabyN, FokP, LuongTM, HomierV.
