The procedures in the world of welding all look simple, but all welding that looks simple must have extensive knowledge in accordance with the definition of welding. This welding is a permanent connection technique, when the welding process takes place the results do not always meet the quality standards that have been determined. The cause of the welding results that do not meet the quality standards in the form of dirt on the material when before welding and so forth. The purpose of this study is that the specimen specimens are accepted according to the welding institute's standard acceptance criteria (TWI) This research uses st 37 steel by using SMAW welding electrodes LB 52U (E 7016) diameter 2.6mm for root, and LB 52U (E 7016) diameter 3.2 for fillers and caping with welding position 1G. Testing of welding results is carried out by the non destructive test of the dye penetrant method whose inspection results are determined based on the standard ASME. The results of this test study discontinuity in the form of porosity on the surface of the welding results in specimen 1, namely material contaminated by dirt, there are porosity defects scattered with a length of 6mm and porosity of 10mm so based on the standard TWI both test specimens were declared rejected, and in specimen 2, material that was not contaminated with impurities, there were porosity defects of 2mm and 2.5mm so that according to the standards of the two specimens the test was accepted. For the results of welding defects that are rejected can still be corrected by linking to the defects that, and can be done welding again.

The assessment of human health risks resulting from the presence of metabolites in groundwater and food residues has become an important element in pesticide authorisation. In this context, the evaluation of mutagenicity is of particular interest and a paradigm shift from exposure-triggered testing to in silico-based screening has been recommended in the European Food Safety Authority (EFSA) Guidance on the establishment of the residue definition for dietary risk assessment. In addition, it is proposed to apply in silico predictions when experimental mutagenicity testing is not possible due to a lack of sufficient quantities of the pesticide metabolite. This, combined with animal welfare and economic considerations, has led to a situation where an increasing number of in silico studies are submitted to regulatory authorities. Whilst there is extensive experience with in silico predictions for mutagenicity in the chemical and pharmaceutical industry, their suitability in pesticide regulation is still insufficiently considered. Therefore, we herein discuss critical issues that need to be resolved to successfully implement (Quantitative) Structure-Activity Relationship ((Q)SAR) as an accepted tool in pesticide regulation. For illustration purposes, the results of a pilot study are included. The presented study highlights a need for further improvement regarding the predictivity and applicability domain of (Q)SAR systems for pesticides and their metabolites, but also raises other questions such as model selection, establishment of acceptance criteria, harmonised approaches to the combination of model outputs into overall conclusions, adequate reporting and data sharing. © 2020 The Authors.

Requirements negotiation is a centralized process of making a decision in order to resolve conflicts in the requirements of the stakeholder. The negotiation will enable the shared vision of software to be developed among the heterogeneous stakeholder in the software industry to be achieved. Many process models used for the negotiation of stakeholder’s requirements have been proposed for the software industry by the research community, yet the acceptance of these process models is discouraging. This study tends to investigate the inadequate adoption of requirements negotiation process models. Further, it finds the acceptance criteria for the software industry to adopt requirements negotiation models. Finding shows that the software industries do not adopt the process models. The perceived usefulness, perceived ease of use and many more criteria have been identified through the literature review on the general criteria of software systems acceptance.

Based on the 1945 Constitution of the Republic of Indonesia – Article 37 of 2009 verse 8 states that a lecturer profession obliges to a minimum of 12 and maximum of 16 teaching credits in every semester according to his/her academic qualifications. Todays, Institute of Information Management and Computer Science (STMIK) Widuri has been applying a sharing knowledge process amid lecturers with the intention to assist them in academic position ladder management. However, problems are found during its implementation. First problem is infrequentTri Dharma practices (three principles of higher education; education, research and contribution to society)and reports being submitted by lecturers; the condition has resulted a statistic of STMIK active lecturers in general to decrease to 41.6%. Lack of information regarding Tri Dharma practices and its administrations known by its lecturers is the one missed to solve; a lecturer does not comprehensively understand what the stages are required in order to administer their academic position ladder. Second issue is there has been no media to facilitate lecturers to spread and share the knowledge and experience with the other fellow lecturers that the process of levelling up their academic tenures or positions become hampered. This means, the slower the process the longer it takes for them to move up to the next academic position ladder. As this is the case, the researchers propose aprototype of knowledge management system (KMS) utilizing SECI methodand gathering data through interviews, observations as well as literature studies. Software used is User Acceptance Test (UAT). Furthermore, the research has come up with a web-based KSM prototype with test percentage result76%; this means the system is accepted and matched the expectation.

According to the Korea Radioactive Waste Agency’s (KORAD’s) medium and low level radioactive waste management implementation plan, the Domestic 3rd Step Landfill Disposal Facility has planned to accept a total of 104,000 drums (2 trenches) of very low level radioactive waste (VLLW), from the decommissioning site from April 2019 - February 2026 (total budget: 224.6 billion Won). Subsequently, 260,000 drums (5 trenches) will be disposed in a 34,076 m2. Accordingly, KORAD is preparing a waste acceptance criteria (WAC) for this facility. Every disposal facility for VLLW in other countries such as France and Spain, operate their WAC for each VLLW facility with a reasonable application approach, This, paper focuses on analyzing the WAC conditions in VLLW sites in the USA and discusses whether these can be met in domestic VLLW WAC. It also helps in the preparation of WAC for the 3rd Step Landfill Disposal Site in Gyeongju, since the USA has prior experience on decommissioning nuclear waste.

The article presents the method of qualifying orbital welding technology using the TIG (142) method of the perforated bottom heat exchanger made of steel A516M (Grade 485) explosively clad with titanium B265 (Grade 1) with titanium pipes B338 (Grade 2) with a diameter of 34.93 mm and thickness 0.7 mm. Based on preliminary tests, welding technologies have been developed that meet the acceptance criteria for acceptance requirements. Qualification of the developed technology and welding parameters that were used during welding was carried out in accordance with PN-EN ISO 15614 Specification and qualification of metal welding technology, welding technology testing, Part 8: Welding of tubes with perforated bottom.

There has been observed explosive growth in the development of mobile applications (apps) for Android and iOS operating systems, which has led to the direct impact towards mobile app development. In order to design and propose quality-oriented apps, it is the primary responsibility of developers to devote time and sufficient efforts towards testing to make the apps bug-free and operational in the hands of end-users without any hiccup. Manual testing procedures take a prolonged amount of time in writing test cases, and in some cases, the full testing requirements are not met. Besides, the insufficient knowledge of tester also impacts the overall quality and bug-free apps. To overcome the obstacles of testing, we propose a new testing methodology cum tool called “AgileUATM” which works primarily towards white-box and black-box testing. To evaluate the validity of the proposed tool, we put the tool in a real-time operational environment concerning mobile test apps. By using this tool, all the acceptance criteria are determined via user stories. The testers/developers specify requirements with formal specifications based on programs properties, predicates, invariants, and constraints. The results show that the proposed tool generated effective and accurate test cases, test input. Meanwhile, expected output was also generated in a unified fashion from the user stories to meet acceptance criteria. The proposed solution also reduced the development time to identify test data as compared to manual Behavior-Driven Development (BDD) methodologies. This tool can support the developers to get a better idea about the required tests and able to translate the customer’s natural languages to computer languages as well. This paper fulfills an approach to suitably test mobile application development.

Daylighting provision is an efficient approach in achieving a healing environment. Several researches praised the effect of daylight on stress reduction, shorter hospital length of stay, and the increasing of patients’ satisfaction. The building facade has the primary role in controlling the indoor environment. In addition to daylighting, Double-Skin Facade (DSF) is an approach that can create a balance between patients’ needs without sacrificing energy reduction and thermal comfort in the hot arid desert climate. This paper aimed at investigating the effect of fixed horizontal louvers integration in a multi-story double-skin facade to enhance daylighting performance and visual comfort in south-oriented patient rooms located in Cairo, Egypt. Rhinoceros software was used for modeling the proposed designs coupled with Diva-4-Rhino for daylighting simulations. The effect of changing louver’s depth and slats’ number resulted in 16 designs that were modeled for examination. Daylighting performance was analyzed by two metrics; Spatial Daylight Autonomy (sDA) and Annual Sunlight Exposure (ASE) on both the room surface floor and bed surface planes to represent daylight distribution and visual discomfort, respectively. Results showed that all cases were successful, achieving 100% sDA value on the bed plane area. However, the sDA and ASE values at the room floor area were different. Three louvered double-skin facade designs have succeeded in meeting sDA and ASE acceptance criteria and were recommended for integrating in patient rooms. Also, it was noticed that the unshaded double-skin facade presented the worst performance.

The operation of a good system in a company is inseparable from the support of business partners, but it is impossible to obtain if the partner or supplier of goods does not work as the target of the company itself. Given these problems, it is deemed necessary to create a DSS system that can assist directors in determining suitable suppliers to work together. In making this SPK, the SAW method starts from the selection of types of goods, selects criteria and sub-criteria, and determines the weights of each criterion.This study produced an SPK, with six main criteria and their respective weights, based on the criteria entered and processed in accordance with the rules of the SAW method, CV. Eka Makmur was chosen as the most suitable recommendation to become a supplier for all in one PC items. At the testing stage, three methods have been carried out namely black box, output testing, and user acceptance test.

Administrative and financial information systems are one of the most widely applied information technologies to facilitate the management of various data into information. But the TK Hati IT-TK Hati Sumberrejo still uses manual methods in processing student, teacher and staff data as well as payment data in the form of SPP payments, POMG, uniforms and activities. Data processing is done using Microsoft Excel, which results in time consuming when entering data and when re-doing data correction before reported to the Principal. This system was developed aiming to help data and financial management to be more effective and efficient. So, the information from the data entered can be conveyed properly. Therefore, it is necessary to develop a web-based administrative and financial management information system using PHP as a programming language with laravel framework. This system is designed using the waterfall method with six stages. Then the system will be evaluated using the Black Box Test and User Acceptance Test. The results of this study are an information system with various features that can be used to manage student, teacher and staff data, as well as to manage recap payments of SPP fees, POMG, uniforms and activities. The results of the system testing by the Principal, Treasurer staff, Administrative staff, and Admin staff can be concluded that the system is running well and meets the needs of the school.

A compact accelerator mass spectrometry (AMS) system dedicated to measuring 14C was installed at the Dongguk University, Korea. Standards SRM 4990B (Ox-I), SRM 4990C (Ox-II), IAEA C-7, and IAEA C-8 were used to conduct the acceptance tests. Phthalic acid and IAEA C-1 were used to measure the background level. The results of the acceptance tests demonstrated the radiocarbon dating precision capabilities for 14C/12C and the background level. Moreover, a graphitization system for radiocarbon dating was installed. After installation, the AMS and graphitization systems were used to analyze archaeological, environmental, and petrochemical materials. The environmental samples were measured with AMS to study the relationship between CO2 emissions from fossil fuels and urban environmental variables. Analysis of leaves showed that urban population densities and CO2 emissions from fossil fuels were not significantly related. The cause of CO2 emissions in cities remains under study.

This paper reports variants for checking the median error of the 2Е36 weapon stabilizer under conditions of a standard path by means of video recording with a film camera followed by film processing and performing all operations in a manual mode. A procedure of measuring the median error of the SVU-500 weapon digital stabilizer has been given. To ensure the possibility of determining the errors of stabilization in each set of stabilizers, the enterprise-manufacturer has devised and implemented for the customer's main product, without using a standard path, a new procedure for measuring a dynamic stabilization error. This work involved methods of mathematical modeling, which has made it possible to determine the point of sending a sinusoidal signal to the control circuit of the stabilizer. The experimental confirmation of the results obtained during modeling involved the test of a stabilizer kit at the technological bench and at the actual training turret, which made it possible to refine the parameters of the sinusoidal signal. To conduct such tests, special algorithmic software was developed, which was installed, in addition to the main program at the time of testing, in the stabilizer control unit. Subsequent tests confirmed correctness of results obtained during mathematical modeling, which made it possible to introduce verification of one of the main parameters of stabilization of dynamic error to the acceptance tests of each stabilizer kit, В статье приведены варианты проверки серединной погрешности стабилизации стабилизаторов вооружения 2Е36 в условиях типовой трассы методом кинофотографирования с помощью кинокамеры с последующей обработкой кинопленки и выполнения всех операций в ручном режиме.

Most of the existing weld quality acceptance criteria stipulated in various codes and standards, as well as in recommended practices, are empirical in nature. Historically, these workmanship-based criterias have been adequate for quality control purposes in construction of welded structures. However, as the competition for achieving structural lightweighting intensifies, more quantitative quality acceptance (also known as fitness-for-purpose based) criteria are increasingly called for. This is because various new forms of discontinuities and joint configurations (e.g., dis-similar materials joints) cannot be readily related to existing acceptance criteria. Even if existing criteria can be made applicable, recent research findings have shown that existing criteria can be excessively conservative for some and unconservative for others when dealing with thin gauge and lightweight construction. A similar situation exists for additively manufactured metallic components, which can be viewed as “all weld metal” components containing randomly distributed discontinuities over the entire component volume. In this paper, some of the recent developments in quantitative weld quality acceptance criteria will be first highlighted, some of which are made possible by advanced fracture mechanics analysis techniques. Applications in structural lightweighting and additive manufacturing will then be demonstrated with some real-world examples. Finally, implications on a broader application of the methodologies presented for ensuring both structural integrity and cost-effectiveness in construction will be discussed in light of these developments.

Ergonomics assessment in the automotive industry has to date focussed mainly on physical ergonomics, for example manual handling and posture. However, it is recognised that workload, in particular metabolic and cognitive workload, contribute to worker efficiency but does not currently receive sufficient attention to yield practical guidance for industry. Successful workload assessment requires in-depth understanding of the context in which it will be conducted, and of the various assessment techniques which will be applied with consideration given to factors such as feasibility, resources and skill of the assessor. These requirements are met with challenges within large and complex organisations and are often dealt with in a piecemeal and isolated matter (i.e. reactive workload assessment). The present paper explores these challenges within the automotive manufacturing industry and aims to develop a decision matrix to guide effective selection of workload assessment techniques focused on metabolic and cognitive demands. It also presents the requirements for time, equipment and knowledge to implement these techniques as part of a participatory ergonomics approach. Early findings suggest that most assessment techniques reviewed require further development, for example, to establish the acceptance criteria for the specific workload scenario. However, five methods (Garg, Borg RPE, IPAQ, SWAT and NASA-TLX) are ready to use in certain applications. Ultimately the findings suggest that it is possible to implement a participatory workload evaluation program within large and complex manufacturing plants.

The self-compacting concrete (SCC) mix design is much more complex than that of ordinary concrete. Increased testing on fresh concrete and a substantial volume of materials is consequently needed. The concrete equivalent mortar (CEM) method proposes an approach that simplifies and speeds up the experimental testing programmes. This paper seeks to establish the relationships between the rheological properties of SCC and the corresponding CEM mixes. Another aim is to validate the unconventional tools used to test the flow properties of CEM relative to the procedures applied for SCC. Different series of SCC and CEM mixes, based on natural and recycled aggregates, with various superplasticizer contents were tested. The flow behaviour of SCC was tested in line with procedures recommended by EFNARC; that of self-compacting concrete equivalent mortar (SC-CEM) was carried out with unconventional tools (mini-slump cone, slump flow time T250, mini L-Box, 2.5-mm sieve, and mini LCPC Box), described in detail in this paper. A rheometer equipped with vane geometry was also used to show the close relationship between SCC and the SC-CEM yield stress. The experimental results indicate that the fresh properties of the mixture series are congruent with the acceptance criteria of SCC, but they are affected when increasing the superplasticizer dosage and further impacted when recycled coarse aggregates (RCAs) replace natural coarse aggregates (NCAs). The slump flow test appears to be a good practical means for predicting the yield stress of SC-CEM. The cross-referencing results reveal significant relationships between SCC and the corresponding SC-CEM, particularly for filling ability and passing properties. Reasonable correlation coefficients from 0.70 to 0.85 were found.

Partial discharge (PD) detection and analysis plays a crucial role for acceptance testing and condition monitoring of power cables. Various aspects are related to PD in power cables from theory to practice. This paper first summarizes the PD mechanism and models used for PD analysis in power cables. Afterwards, PD detection is addressed in the aspects of off-line test, on-line test, and sensors. PD analysis is discussed in detail. Specifically, related quantities and algorithms for PD analysis are outlined. PD characteristics with affecting factors, e.g., dielectric type, load, and applied voltage are discussed. Experience on PD development trend with measurements in field is analyzed. Based on the comprehensive review, challenges of PD detection and analysis along a power cable are proposed.

This paper addresses to the issue of program organization and testing attempts to accept with 6 phases machines, a less researched field. According to the standards, several tests, in particular those of experimental definition of the parameters, it must be performed at a sinusoidal supply voltage, which imposes the need to develop and manufacture new test equipment, involving substantial costs. The paper argues for a way to perform tests that require sinusoidal voltage supply, by transforming the six-phase asynchronous machine (with an even number of three-phase systems) by simple procedures for reconnecting the phase windings, in a symmetrical three-phase. This allows tests to be performed in no-load operation, with load and short-circuit mode, using the standard equipment of three-phase electrical machine testing laboratories. This eliminates the need for new multiphase sinusoidal power supply equipment.

In contrast with common buildings, the limit-state assessment has not been applied to pipe-rack – piping systems yet, albeit the seismic vulnerability of critical pipes is rather high. The current engineering practice may design pipe rack – piping systems in a risk-inconsistent way due to the conservative acceptance criteria of seismic codes that keep pipes in the elastic range. Additionally, the response of pipes could become complex when considering differential displacements between internal supports, pipe edges and adjacent structures, which static methods may not describe efficiently. The design of a typical RC pipe rack – piping system in a code-consistent way resulted in two main outcomes. First, the piping required the increase of structural members cross-section, and secondly, the differential displacement was the main reason of pipe failure both in the longitudinal (unrestrained) as well as transverse direction. Finally, the performance-based assessment of this type of system demonstrated that the spectral acceleration is mildly more efficient and sufficient intensity measure than ground ones to describe the damage on piping. The observed mean annual frequency of exceedance was 57% smaller than the targeted value for the pipes, whereas the difference was considerably higher for the pipe rack. This outcome corroborated the conservativeness of codes and the risk-inconsistency between the structural and non-structural members.

In this paper, different non-powered hand tools such as tweezers, pliers, or screwdrivers are assessed with respect to their ESD risk. The ESD properties of the tools are evaluated using resistance measurements and discharge current measurements between the tool and devices. Acceptance tests for non-powered hand-tools are proposed.

[EN] In recent years and after the strong impact of the last global health emergency (COVID-19) information and communication technologies have had a great impact on society but particular in the teaching-learning process. Education has been impacted at all its levels. Therefore, education models have been to be adapted to this new challenging paradigm by using different tools such as videoconferences, simulations, on-line interactive applications, virtual and remote laboratories, robots, etc. The objective of this work is to elaborate a systematic mapping to know what scientific from its beginning to 2020, identifying the most literature exists regarding simulators, remote and virtual laboratories focused on STEM/STEAM skills development in the educational context. To do so, bibliographical data gathered of four of the most popular and complete electronic databases (ACM, IEEE, Scopus and Web of Science). At the begging we selected 1232 articles after applying the acceptance criteria defined as part of the search and select strategy, we had 61 articles that help us to answer some questions like what are the most popular virtual and remote labs? or what are the current trends and issues of these tools? and the future ones?

Test coverage is a standard measure used to evaluate the completeness of a test suite. Coverage is typically computed on source code, by assessing the extent of source code entities (e.g., statements, data dependencies, control dependencies) that are exercised when running test cases. When considering REST APIs, an alternative perspective to assess test suite completeness is with respect to the service definition. This paper presents Restats, a test coverage tool for REST APIs that supports eight state-of-the-art test coverage metrics with a black-box perspective, i.e., only relying on the OpenAPI interface specification of the REST API under test. In fact, metrics are computed by only observing the HTTP requests and responses occurring at testing time, and no access to source/compiled code of the REST API is required. These coverage metrics come in handy for: (i) developers and test engineers working at development and maintenance tasks; (ii) stakeholders and customers who want to evaluate the completeness of acceptance tests; (iii) researches interested in comparing different automated test case generation strategies.

Ground improvement was required for construction of the Jaber Al Ahmed New City located about 25 km west of Kuwait City, Kuwait. Loose to medium poorly graded sands, and silty sands extended from ground level to a depth ranging from 5m to 9m. Dynamic compaction was employed, as an economic method, to increase the soil bearing capacity and reduce its compressibility for foundation design and construction. The testing program included borings and sampling, Standard Penetration Tests, Cone Penetration Tests and Pressuremeter Tests before and after dynamic compaction. The area covered in this study is about 31415m2. The results indicated significant ground improvement, and satisfaction of the specified acceptance criteria resulting in an allowable soil pressure, for shallow foundation design, equal to or exceeding 300 kN/m2.

Since the beginning of year 2020, SARS-CoV-2, better known as COVID-19 disease, has forced companies across the globe to come up with new digital ways to conduct business. As the world continues to adapt to changes that affect travel and movement, it was recognized the urgent need to design and deploy solutions that can keep business running while ensure the same level of accountability, trust and communication as ever. Among the different challenges faced in the last year, one of the major one was how to carry out Factory Acceptance Tests (FAT) on a short time and without on-site customers allowed visiting the factory. This paper introduces a new, modular, and cheap way to perform FAT from remote for sustainable industrial processes and it provides a brief description of its implementation by means of only Commercial Off-The-Shelf (COTS) hardware and software easily available on the markets. Methods and strategies are presented, including useful insights for Navigational Aids (Navaids) business and possible future improvements and enhancements.

Traditional requirements engineering does not benefit from modern software development techniques. The goal of this tutorial is to revisit requirements elicitation and to bridge the gap between traditional requirements engineering and modern software development. This tutorial will provide the attendees with concrete and immediately applicable guidance by demonstrating how to operationalize a fully-fledged toolchain going from user stories to automated acceptance testing using open-source tools.

Effort estimation is an integral part of activities planning in Agile iterative development. An Agile team estimates the effort of a task based on the available information which is usually conveyed through documentation. However, as documentation has a lower priority in Agile, little is known about how documentation effort can be optimized while achieving accurate estimation. Hence, to help practitioners achieve just-enough documentation for effort estimation, we investigated the different types of documented information that practitioners considered useful for effort estimation. We conducted a survey study with 121 Agile practitioners across 25 countries. Our survey results showed that (1) despite the lower priority of documentation in Agile practices, 98% of the respondents considered documented information moderately to extremely important when estimating effort, (2) 73% of them reported that they would re-estimate a task when the documented information was changed, and (3) functional requirements, user stories, definition of done, UI wireframes, acceptance criteria, and task dependencies were ranked as the most useful types of documented information for effort estimation. Nevertheless, many respondents reported that these useful types of documented information were occasionally changing or missing. Based on our study results, we provide recommendations for agile practitioners on how effort estimation can be improved by focusing on just-enough documentation., To be published at International Conference on Software Maintenance and Evolution (ICSME) 2021

The cataloguing and revision of reactor pressure vessels (RPV) manufacturing and in-service inspection codes and their standardized material specifications—as a technical heritage—are essential for understanding the historical evolution of criteria and for enabling the comparison of the various national regulations, integrating the most relevant results from the scientific research. The analysis of the development of documents including standardized requirements and the comparison of regulations is crucial to be able to implement learned lessons and comprehend the progress of increasingly stringent safety criteria, contributing to sustainable nuclear power generation in the future. A novel methodology is presented in this work where a thorough review of the regulations and technical codes for the manufacture and in-service inspection of RPVs, considering the implementation of scientific advances, is performed. In addition, an analysis focused on the differences between irradiation embrittlement prediction models and acceptance criteria for detected defects (both during manufacturing and in-service inspection) described by the different technical codes as required by different national regulations such as American, German, French or Russian is performed. The most stringent materials requirements for RPV manufacturing are provided by the American and German codes. The French code is the most stringent with respect to the reference defect size using as a criterion in the in-service inspection.
