Abstract:
Background:Depressive disorder is common in adolescents and largely untreated. Computers offer a way of increasing access to care. Computerized therapy is effective for depressed adults but to date little has been done for depressed adolescents.Aims:The objective of this study was to examine the feasibility, acceptability, and effects of The Journey, a computerized cognitive behavioural therapy (cCBT) program for depressed adolescents.Method:Thirty-four adolescents (mean age 15.2 years,SD= 1.5) referred by school counsellors were randomly assigned to either cCBT or a computer-administered attention placebo program with psychoeducational content (CPE). Participants completed the intervention at school. Data were collected at baseline, post-intervention and at a 1-month follow-up. The primary outcome measure was the Child Depression Rating Scale Revised (CDRS-R); secondary outcome measures were: RADS-2; Pediatric Quality of Life Inventory; Adolescent Coping Scale (short form); response and remission rates on CDRS-R. Completion rates and self-reported satisfaction ratings were used to assess feasibility and acceptabililty of the intervention.Results:Ninety-four percent of cCBT and 82% of CPE participants completed the intervention. Eighty-nine percent liked The Journey a lot or thought it was “okay” and 89% of them would recommend it for use with others as is or after some improvement. Adolescents treated with cCBT showed greater symptom improvement on CDRS-R than those treated with CPE program (mean change on cCBT = 17.6, CI = 14.13–21.00; CPE = 6.06, CI = 2.01–10.02;p< .001).Conclusions:It is feasible, acceptable and efficacious to deliver computerized CBT to depressed adolescents in a school setting. Generalizability is limited by the size of the study.

Abstract:
Summary Objectives: To assist general practitioners in evaluating patients’ genetic risk of cancer on the basis of family history data. Methods: A new computer application, RAGs (Risk Assessment in Genetics), has been developed to help doctors create graphical family trees and assess the genetic risk of breast and colorectal cancer. RAGs possesses two features that distinguish it from similar software: (i) a user-centred design, which takes into account the requirements of the doctor-patient encounter; (ii) effective and accessible risk reporting by employing qualitative evidence for or against increased risk, which is more easily understood than numerical probabilities. The system allows any rule-based genetic risk guideline to be implemented, and may be readily modified to cater for the varying degrees of information required by different specialists. Results: RAGs permits fast, accurate data entry, and results in more appropriate management decisions than those made via other techniques. In addition, RAGs enables both the clinician and the patient to understand how it arrives at its conclusions, since the use of qualitative evidence allows the program to provide explanations for its reasoning. Conclusions: The RAGs system promises to help practitioners be more effective gatekeepers to genetic services. It may empower doctors both to make an informed choice when deciding to refer patients who are at increased genetic risk of breast or colorectal cancer, and to reassure those who are at low risk.

Abstract:
Despite the positive outcome of the recent randomized trial of computed tomography (CT) screening for lung cancer, substantial implementation challenges remain, including the clear reporting of relative risk and suggested workup of screen-detected nodules. Based on current literature, we propose a 6-level Lung-Reporting and Data System (LU-RADS) that classifies screening CTs by the nodule with the highest malignancy risk. As the LU-RADS level increases, the risk of malignancy increases. The LU-RADS level is linked directly to suggested follow-up pathways. Compared with current narrative reporting, this structure should improve communication with patients and clinicians, and provide a data collection framework to facilitate screening program evaluation and radiologist training. In overview, category 1 includes CTs with no nodules and returns the subject to routine screening. Category 2 scans harbor minimal risk, including <5 mm, perifissural, or long-term stable nodules that require no further workup before the next routine screening CT. Category 3 scans contain indeterminate nodules and require CT follow up with the interval dependent on nodule size (small [5-9 mm] or large [≥10 mm] and possibly transient). Category 4 scans are suspicious and are subdivided into 4A, low risk of malignancy; 4B, likely low-grade adenocarcinoma; and 4C, likely malignant. The 4B and 4C nodules have a high likelihood of neoplasm simply based on screening CT features, even if positron emission tomography, needle biopsy, and/or bronchoscopy are negative. Category 5 nodules demonstrate frankly malignant behavior on screening CT, and category 6 scans contain tissue-proven malignancies.

Abstract:
In this paper, an automatic technique for test timing assignment is proposed which is comprehensive enough to take the test objective (e.g., strictness of selected AC timing parameters) and the constraints from both RAM specification and tester into consideration. Since test timing assignment problem could only be solved manually before, therefore, our work can significantly reduce the efforts and costs on developing and maintaining timing modules of RAM test programs. In the proposed technique, the test timing assignment problem is transformed into a linear programming (LP) model, which can be automatically solved. Examples of building LP models for an asynchronous DRAM are given to show feasibility of the proposed technique.

Abstract:
Purpose To assess and develop solutions for an ultrasound-based breast cancer early detection program in rural South Africa 1 year after implementation. Methods A WHO-endorsed RAD-AID Radiology Readiness Assessment was used to evaluate clinic resources. In addition, 5 weeks of observation identified resource deficiencies and reviewed existing documentation methods. On the basis of stakeholders’ input and the BI-RADS, we developed new documentation systems. Training was followed by a survey that assessed feasibility and provider acceptance. Results Resource limitations included lack of computers, unpredictable electrical supply, and inconsistent Internet. The assessment revealed incomplete documentation of breast clinical examinations and history, breast lesions, and follow-up. Furthermore, limitations negatively affected communication among providers. Three solutions were developed: a paper patient history form, a paper clinical findings form, and a computerized patient-tracking data base compliant with BI-RADS. Three nurses, three nursing assistants, and one counselor completed the survey. Seventy-one percent indicated positive general attitudes, and 100% agreed that the documentation system is easy and useful and improves overall quality of care, follow-up, decision making; access to clinical information; and communication between clinicians and patients. Five of the seven providers reported that the system increased visit time, but three of those five believed that the process was valuable. Conclusion Implementation of a breast cancer early detection program in resource-limited regions is challenging, and continual assessment is essential. As a result of identified needs, we developed a documentation system that was broadly accepted. Future steps should focus on increasing efficiency, evaluation of provider attitudes long term, and clinical effect.

Abstract:
A escala de Basso, Beattie e Brenahan (BBB) serve para avaliação da recuperação locomotora em ratos com lesão medular nos níveis torácicos. É baseada em critérios observacionais da movimentação do animal durante a marcha e atribui uma pontuação de 0 a 21 segundo a gravidade da lesão neurológica. Menor pontuação, maior gravidade. Tal escala pode ser aplicada de modo livre, em que o pesquisador observa o rato e emite uma nota; pode ser aplicada de modo dirigido, em que o pesquisador segue uma sequência de perguntas pré-estabelecidas e atribui uma nota; ou de modo automatizado, em que as respostas à mesma sequência de perguntas são fornecidas a um programa de computador, que emitirá uma nota com o grau de lesão. Trabalhos já publicados mostram que existe variação interobservadores na aplicação desta escala. O objetivo do trabalho foi avaliar a utilização de um programa de computador para auxiliar os pesquisadores na atribuição de notas na aplicação da escala BBB e comparar as notas obtidas por esses pesquisadores quando o fazem de modo livre, dirigido e utilizando um programa automatizado. Para testar o programa, foi realizada lesão medular padronizada em 12 ratos Wistar utilizando-se metodologia da New York University - Impactor System. Na sequência, filmou-se a movimentação dos ratos para aplicação da escala BBB no 28o dia. Foram convocados oito pesquisadores do laboratório de estudos de trauma raquimedular da Universidade de São Paulo. As avaliações de dois chefes do laboratório, com 15 anos de experiência na aplicação da escala, foram consideradas o padrão ouro na avaliação. Seis pesquisadores receberam as filmagens dos ratos com o objetivo de aplicar a escala BBB nas três metologias: livre, dirigida e automatizada, com 15 dias de intervalo entre as avaliações. A ordem da aplicação da escala foi randomizada entre os pesquisadores e a ordem dos ratos, nas análises das filmagens, também foi variada para evitar a memorização por parte dos pesquisadores. Os resultados interavaliadores e entre os métodos mostraram-se similares. A comparação dos resultados entre os seis pesquisadores e os dois considerados padrão ouro mostrou diferença para dois pesquisadores nos métodos livre e dirigido. Concluiu-se que a aplicação da escala BBB pelo modo automatizado não apresentou diferença em relação ao padrão ouro para todos os avaliadores, e que, quando feita pelo modo livre, dirigido e automatizado, não apresentou diferença em relação ao padrão ouro, considerando a média dos avaliadores em cada método
The BBB is an evaluation scale in the locomotor recovery in rats presenting thoracic medullar injury. It is based on observation criteria of animal movement while walking, and a provides a score ranging from 0 to 21 according to the severity of the neurological injury. The lower the score, the higher the severity. Such scale can be applied by using a free system of analysis, that is, when the researcher observes the rat and gives a score. The evaluation can also be made in an assisted way, where the researcher follows a series of pre-established questions and then gives a score,or in an automated manner, where the answers to the same sequence of questions are provided to a computer program, which provides a score with the degree of injury. Published research shows that there is a interobserver variation in the scale application The objective of the present study was to evaluate the use of a computer program for helping researchers in the scoring by the BBB scale, and comparing these grades obtained when they are making a free evaluation, in an assisted evaluation and while using a computer program. In order to test the program, a standardized spinal cord injury was performed in 12 Wistar rats in accordance with the methodology proposed by the New York University - Impactor System. Then, the rat movements were filmed on the 28th day, so that the Basso, Bettie and Bresnahan scale could be applied. Eight researchers working in the spinal cord injury laboratory in the University of São Paulo were invited for the study. Two heads of the laboratory, with a fifteen year-experience in the usage and application of the scale, were considered to be gold standard in the evaluation. Six researchers were shown the films and asked to apply the BBB scale by the three methodologies: free, assisted and computerized, with a fifteen-day interval between evaluations. The scale application order was randomized among the researchers as well as the order of the rats in the film analysis so as to avoid memorization on the part of the researchers. Results proved to be similar between researchers and methods. The comparison of results among the six researchers and the gold standard ones showed discrepancies in two of the researchers in the free and assisted methods of analysis. It was concluded that the BBB scale evaluated through the computer method was no different than the gold standard for all the researchers. When the analysis was performed using the free, assisted and computer-assisted methods, no difference was observed in relation to the gold standard considering the mean values in each method

Abstract:
The paper considers the issues of implementation and application of intelligent computing on the basis of cognitive and event modeling in research on energy security. The authors suggest a two-level information technology for the research. The first level suggests a situation analysis using the intelligent computing techniques. The analysis results are then used to choose rational variants of energy development in Russia (or its regions). At the second level these variants are computed with the multi-agent software INTEC-M. Transition from the first to the second level is automated by the tools of deductive program synthesis, that are based on declarative descriptions, i.e. formulae of restricted predicate calculus, and representation of input data by XML files. Cognitive and event modeling is considered in more detail. The examples of cognitive and event models are presented. The structure of a knowledge space is developed to support the intelligent computations. The knowledge space includes ontological models, databases of cognitive and event models, and the database on the cases of energy emergency situations. The authors developed the CogMap and EventMap tools to support cognitive and event modeling on the basis of common graphical environment GirModeling, and the expert system “Emergency”. The tools and expert system that support the knowledge base on energy emergencies are integrated within the intelligent IT environment. The research presented in the paper was partially supported by the grant of Presidium of RAS No. 2.2-2012 and grants of Russian Foundation of Basic Research No. 10-07-00264, No. 11-07-00192, No. 11-07-00245, and No. 12-07-00359.

Abstract:
Variables and parameters required to characterize soil water flow and solute transport are often measured at different spatial scales from those for which they are needed. This poses a problem since results from field and laboratory measurements at one spatial scale are not necessarily valid for application at another. Herein lies a challenge that vadose zone hydrologists are faced with. For example, vadose zone studies can include flow at the groundwater-unsaturated zone as well as at the soil surface-atmosphere interface at either one specific location or representing an entire field or landscape unit. Therefore, vadose zone measurements should include techniques that can monitor at large depths and that characterize landsurface processes. On the other end of the space spectrum, microscopic laboratory measurement techniques are needed to better understand fundamental flow and transport mechanisms through observations of pore-scale geometry and fluid flow. The Vadose Zone Hydrology (VZH) Conference made very clear that there is an immediate need for such microscopic information at fluid-fluid and solid-fluid interfaces, as well as for methodologies that yield information at the field/landscape scale. The need for improved instrumentation was discussed at the ASA-sponsored symposium on “Future Directions in Soil Physics” by Hendrickx (1994) and Hopmans (1994). Soil physicists participating in the 1994-1999 Western Regional Research Project W-188 (1994) focused on “improved characterization and quantification of flow and transport processes in soils,” and prioritized the need for development and evaluation of new instrumentation and methods of data anlysis to further improve characterization of water and solute transport. The regional project documents the critical need for quantification of water flow and solute transport in heterogeneous, spatially variable field soils, specifically to address preferential and accelerated contaminant transport. Cassel and Nielsen (1994) describe the contributions in computed tomography (CT) using x-rays or magnetic resonance imaging (MRI) as “an awakening,” and they envision these methodologies to become an integral part of vadose zone research programs. The difference in size between measurement and application scales poses a dilemma for the vadose zone hydrologist.

Abstract:
In recent years computational fluid dynamics (CFD) has demonstrated the ability to predict sail and appendage forces under upwind conditions or at angles of attack conducive to attached flow. Few sail or yacht designers would be without this tool, at least to check or confirm performance estimates made with other methods. More advanced codes (RANS) solve the full Navier-Stokes equations, thus including viscous effects and placing relatively less importance to fully attached flow. Due to the large proportion of downwind sailing, where the sails might operate in separated airflow, it is useful to evaluate the performance of sails as used off wind despite the added uncertainty resulting from the elasticity of the light material that must be used to allow the sails to fill properly at the low relative wind speeds. While downwind sail forces have been often tested in wind tunnels, CFD codes are now sufficiently advanced to predict such forces with confidence similar to that achieved in prediction of upwind forces. This paper presents a new method of linking a CFD code with a Finite Element Analysis (FEA) computer program, for evaluating the sail shapes and proper trim for known sail materials and fiber orientation. A VPP (Velocity Prediction Program) is used to predict leeway, heel, and boat speed for a given true wind angle and wind speed. Then the CFD code computes the airflow around the sails for the given onset flow conditions and provides the pressure distribution on the sails as needed for the FEA program. This is done in full scale considering the boundary layer above the water. This process of updating the pressure for the FEA program from the CFD code is repeated several times until optimal trim and sail shapes can be obtained for best sailing performance, e.g., the maximum driving force. Thus, this method can be considered a "Virtual Wind Tunnel" (VWT).

Abstract:
A Blowout Preventer (BOP) consists of several sets of shear rams stacked together out of which Blind Shear Rams (BSR) is a very critical component to achieve complete shearing of drill pipe. The current study focusses on developing a methodology to model the shearing process and validate it with the shop test. Shop tests were conducted to shear a drill pipe using a surface BOP to obtain the maximum shearing force, shape of sheared drill pipes, shearing time etc. The shear rams used in the test are laser scanned and used in FEA simulations. The FEA model is developed such that it replicates the shop test and simulations are performed using Abaqus Explicit finite element solver. The output from simulations and shop test are compared and found to be in good agreement. The developed methodology is further verified by applying it for shearing different drill pipe sizes and the output is compared with the available data and found to be comparative which proves that the methodology can be implemented for various shearing studies. Original Equipment Manufacturer (OEM) formulas are currently being used in industry to compute the maximum shearing force required to shear the drill pipe under various scenarios. The OEM shearing force is computed for the model under consideration and compared with the shop test and simulation and is found to be conservative. The validated model can be used for conducting studies that provide information on the governing parameters in terms of loading or positioning of the drill pipe to be considered in shear ram designs. This study provides a tool for optimizing the preliminary design of new shear rams and can contribute to more reliable and efficient shear ram design. The study is conducted as part of a Technology Assessment Programs (TAP) for the Bureau of Safety and Environmental Enforcement (BSEE) in the areas of BOP stack sequencing, monitoring and kick detection.

Abstract:
Abstract We introduce an optical diagnostics to determine the morphological features of liquid droplet such as the thickness, the contact angle, and the dual profile using internal reflection interferometry. A coherent laser beam is internally reflected on the air/liquid interface of a sessile droplet placed on a prism-based substrate to produce an interference fringe on a screen far from the substrate. The reflected laser rays consist of the reflection from the center spherical droplet profile and the one from the lower hyperbola-like droplet profile. The reflected rays are interfered each other to form the interference fringes. Ray tracing simulation is conducted using a custom-designed computer program. The simulation shows that the interfering rays reflected near the inflection point produce the outer-most fringes of the concentric interference pattern on the screen, and the reflected rays from the apex of the spherical profile and the contact line of the lower hyperbola-like profile construct the fringes at the center of the interference patterns. The simulated results are compared with the experimental observation to show a good agreement in the number and the location of the fringes and the radius of the outer-most-fringe where the number of the fringes is dependent on the droplet thickness and the radius of the fringe depends on the contact angle of the droplet. This result provides a new measurement technique to determine the morphological features of very small microdroplet such as the thickness (&lt; a few micron thickness), the contact angle (&lt; a few degree), and the dual-surface profile.

Abstract:
In most turbine engine testing facilities, the tools and techniques of computational fluid dynamics (CFD) and advanced visualization have never been applied to facilitate (near) real-time analysis of the test hardware. New computer software technology has now been applied which allows server-to-client remote procedure calls (RPC), enabling supercomputers to be called from within the online test scanning program. Coupled with advanced visualization software and graphics workstations, it is possible to view the inside of a test while it is being conducted. Such capability can be as valuable to researchers in steering tests as X-rays are to doctors in diagnosing health. This report presents results from a library of software for on-line visualization. Using this system, a full turbomachine (compressor) has been visually analyzed by interpolating pressure instrument rakes to give a full flow field view of the engine (compressor). All data values at each grid cross-section are non-dimensionalized and viewed at varying ranges of iso-distortion surfaces. Regions of low or high energy can be seen as they proceed through the compressor stages. A full range of capabilities are displayed for both pressure and temperature using computer animation techniques recorded to video. Such views are unique and may provide extra information to help understand flow phenomena such as inlet distortion and how it relates, for example, to stall margin. CFD efforts are also described in conjunction with the use of RPC to supercomputers. A stream function meridional, 2D/quasi-3D solution to five blade rows is shown in context with rotating blade rows and shown on video. The value of the computer work is all generic and can be applied in almost any scientific area where on-line computer systems are used.

Abstract:
During the design of a gas turbine it is required the analysis of all possible operating points in the gas turbine operational envelope, for the sake of verification of whether or not the established performance might be achieved. In order to achieve the design requirements and to improve the engine off-design operation, a number of specific analyses must be carried out. This paper deals with the characterization of a small gas turbine under development with assistance from ITA (Technological Institute of Aeronautics), concerning the compressor variable geometry and its transient operation during accelerations and decelerations. The gas turbine is being prepared for the transient tests with the gas generator, whose results will be used for the final specification of the turboshaft power section. The gas turbine design has been carried out using indigenous software, developed specially to fulfill the requirements of the design of engines, as well as the support for validation of research work. The engine under construction is a small gas turbine in the range of 5 kN thrust / 1.2 MW shaft power, aiming at distributed power generation using combined cycle. The work reported in this paper deals with the variable inlet guide vane (VIGV) transients and the engine transients. A five stage 5:1 pressure ratio axial-flow compressor, delivering 8.1 kg/s air mass flow at design-point, is the basis for the study. The compressor was designed using computer programs developed at ITA for the preliminary design (meanline), for the axisymmetric analysis to calculate the full blade geometry (streamline curvature) and for the final compressor geometry definition (3-D RANS and turbulence models). The programs have been used interatively. After the final channel and blade geometry definition, the compressor map was generated and fed to the gas turbine performance simulation program. The transient study was carried out for a number of blade settings, using different VIGV geometry scheduling, giving indication that simulations needed to study the control strategy can be easily achieved. The results could not be validated yet, but are in agreement with the expected engine response when such configuration is used.

Abstract:
This is the first of two papers describing the validation of a tool chain for flutter prediction. This first paper provides an overview of the numerical methods and their verification. The second paper presents the detailed validation of the tool chain on the basis of experimental data obtained from measurements of an annular cascade sector comprising slightly twisted turbine blades. The tool chain consists of commercial programs for grid generation, structural analysis and the computation of the steady flow, and software developed at DLR for data conversion, aeroelastic preprocessing, and solving the time-linearized RANS equations. The time-linearized solver computes the unsteady flow in the frequency domain based on the linearization of the RANS equations about a steady solution which, in the process chain presented here, is provided by the commercial solver. We investigate the issues that arise from using different spatial discretization schemes and turbulence models for the computation of the steady and the time-linearized solutions. Results are presented for Standard Configurations 4, 10 and 11, and a freestanding turbine blade from a rear stage of a stationary gas turbine. It is shown that with an appropriate choice of the spatial discretization parameters good agreement with reference data can be obtained.

Full text
Abstract:
In this study an academic CFD code, named Galatea-I, is presented, capable for simulating inviscid, viscous laminar and viscous turbulent incompressible fluid flows. It employs the RANS (Reynolds-Averaged Navier-Stokes) approach along with the SST (Shear Stress Transport) turbulence model to predict turbulent flow phenomena, such as recirculations and separations of flow, on three-dimensional unstructured hybrid grids, composed of prismatic, tetrahedral and pyramidal elements. Discretization of the governing equations is obtained with a node-centered finite-volume scheme. Parallel processing and agglomeration multigrid scheme are implemented for the acceleration of the numerical process. As the title of this paper reveals, the solver is validated against the test cases of the DARPA SUBOFF program; in particular, flows over the SUBOFF bare hull submarine geometry at two incident angles and the SUBOFF hull with fairwater configuration are examined. The obtained results, compared to available in open literature experimental data as well as results computed by reference solvers, indicate the proposed methodology’s potential to accurately simulate complex fluid flows.

Abstract:
Because of relaxed requirements on laser-beam uniformity and reduced sensitivity to hydrodynamic instabilities, the ICF Program has concentrated the most of its effort, on the X-ray or indirect drive approach to ICF since 1976. In indirect drive ICF, the driver energy, from laser beams or ion beams, is first absorbed in a high-Z closed cavity which surrounds the capsule, called “hohlraum”. The material heated by the driver emits X-rays, which ultimately drive the capsule implosion. For optimally designed targets, almost 70%–80% of the driver energy can be converted to X-rays. Our main focus is on the view factor calculations for hohlraum geometry of the laser driven indirect ICF approach. This analysis is very important to symmetrically irradiate the ICF capsule. View factor calculations has different radiation heat transfer applications, especially, for indirect drive ICF. In the present work, the obstructed view factor calculations for a square geometry are performed using crossed strings method. For view factor evaluation of the radiation heat transport calculations, different methods are being used. The crossed strings method is much more reliable for simple geometries among the available view factor evaluation techniques. Different cases have been studied for the view factor calculations. These cases include the view factor calculations; if radiations are emitted either from horizontal or vertical axis and a special case for the obstructed view factor calculations. When a third surface is involved in the two already existing surfaces the view factor is said to be the obstructed one rather than the unobstructed ones. Shadow effect method is used for the obstructed view factor calculations. On the other hand, obstructed view factors are computed by subtracting the view factors to the shadows of the obstruction polygons from the unobstructed view factor. The multiple overlaps could become quite complicated while calculating obstructed view factors. Two distinct computer programmes are developed and improved using FORTRAN-90 to evaluate obstructed and unobstructed view factors, for a square geometry. Radiation emission, from both horizontal and vertical surfaces, is considered for calculation of obstructed and unobstructed view factors. The programmes are liabile of calculation for the view factors of variable length of the square square geometry in both horizontal and vertical directions, respectively. In the case of obstructed view factors calculations, certain degree of error was expected. Bench mark of the developed programmes is performed using “Summation Rule”. For the error estimation the unobstructed and obstructed view factors are compared for the similar geometry and found in good agreement, showing the accuracy and reliability of the programmes.

Abstract:
With easy access of the Internet, the real-time, web-based collaborations are impacting the current practices of product design and manufacturing. In this research, an Internet-based manufacturing design system has been developed based on the collaborations of several partners located thousands of miles away from each other. This paper introduces a sub-system of this Internet-based manufacturing system for machined feature estimation and inspection using 3D solid models. Using the engineering data of cutting processes received from our collaborator, through the broadband Internet, taking into account of the factors like cutting forces and tool deflections, this sub-system determines the material removal processes by subtracting the tool cutting volume from work-piece raw material. It creates the machined 3D solid geometry models by simulating the machining processes. The estimated geometry is then taken to a simulated inspection process for engineering analysis and CNC machining program verification. To simulate the inspection process on a Coordinate Measuring Machine (CMM), a series of rays is shot to the machined surface to simulate the CMM probe touching for acquiring surface data. The simulated measurement data is then localized to design surface and comparison between them is made to quantify the machining errors. Through the Internet, the geometrical features and inspection result can be visualized and shared by other sub-systems of the whole manufacturing system based on the commercial CAD data formats. The operation of this subsystem and related facilities is local execution.
