Background: Test-Driven Development (TDD) is an iterative software development process characterized by test-code-refactor cycle. TDD recommends that developers work on small and manageable tasks at each iteration. However, the ability to break tasks into small work items effectively is a learned skill that improves with experience. In experimental studies of TDD, the granularity of task descriptions is an overlooked factor. In particular, providing a more granular task description in terms of a set of sub-tasks versus providing a coarser-grained, generic description. Objective: We aim to investigate the impact of task description granularity on the outcome of TDD, as implemented by novice developers, with respect to software quality, as measured by functional correctness and functional completeness. Method: We conducted a one-factor crossover experiment with 48 graduate students in an academic environment. Each participant applied TDD and implemented two tasks, where one of the tasks was presented using a more granular task description. Resulting artifacts were evaluated with acceptance tests to assess functional correctness and functional completeness. Linear mixed-effects models (LMM) were used for analysis. Results: Software quality improved significantly when participants applied TDD using more granular task descriptions. The effect of task description granularity is statistically significant and had a medium to large effect size. Moreover, the task was found to be a significant predictor of software quality which is an interesting result (because two tasks used in the experiment were considered to be of similar complexity). Conclusion: For novice TDD practitioners, the outcome of TDD is highly coupled with the ability to break down the task into smaller parts. For researchers, task selection and task description granularity requires more attention in the design of TDD experiments. Task description granularity should be taken into account in secondary studies. Further comparative studies are needed to investigate whether task descriptions affect other development processes similarly.

In this work, the design qualification testing, evaluation and test methods of gas generator using double base (DB) propellant having square flake shape is explained for an improvised explosive devices (IEDs) applications. Various kinds of the gas generators are used to save life of an aeronaut in the fastest way from the disable fighter aircraft. Due to their ruggedised design, compactness, safe transportation, repeatability in performance and quick operation, the gas generator are used. The gas generator is designed and developed keeping functional, mechanical and structural requirements in mind. The gas generators are subjected to the various qualification tests, electrical characterisation followed by closed vessel (CV) firings at hot and cold temperatures. The gas generators after the successful qualification tests are validated through the ground trials i.e. dynamic firing of disruptor during the development phase. The damage caused due to impact of the projectile is assessed in terms of crater as acceptance criteria at stand-off distance of 0.5 m and 1m. The gas generator discussed in this research article is used to disrupt the suspected IEDs by creating a high-speed jet using water-jet disruptor. In conclusion, after successful qualification testing, the gas generator for IEDs application meets all the specifications as per user’s requirements.

The success of JISKa is inseparable from the role of reviewers and authors. Unfortunately, JISKa had never been assessed or evaluated by reviewers and authors despite the fact that assessment from the reviewers and authors would be valuable feedback for JISKa’s self-evaluation. Therefore, survey-based research has recently been conducted to assess JISKa’s performance using the User Acceptance Test of OJS version 2.4.8.0. This study used a survey method to obtain an assessment and evaluation from reviewers and authors related to JISKa.The respondents in this study consist of 68 authors and 26 reviewers. The result of this study stated that 91.2% of the authors and 84.6% of reviewers are satisfied with JISKa. A percentage number of 100% of writers and reviewers wants JISKa to raise its level of Sinta accreditation. This accreditation is awarded in 2018 and will end in 2023. JISKa is now on Sinta 4.The JISKa website appearance looks good and easy to use. The dashboard on the JISKa page is user-friendly for the author. However, the current version of JISKa OJS 2.4.8.0 needs to be upgraded to OJS version 3. There are some points for the future consideration of JISKa: JISKa needs to promote itself more, upgrade the OJS version, and provide the reviewers with certificates of appreciation for future consideration.

The results of the study can be used to solve problems related to the development of the testing laboratory of the enterprise, as well as to directly attribute the testing costs to the cost of production..

A 7.5-MW wind turbine drivetrain test bench has been used to apply dynamic loads from IEC 61400-1 design load cases to a multi-MW wind turbine drivetrain. A total of 15 test profiles were tested with each test profile demanding the simultaneous application of vertical, lateral, and longitudinal forces, yawing and nodding bending moments, and rotational speed. These inputs to the test bench were compared with the forces, bending moments, and speed that were applied to the wind turbine drivetrain to quantify the tracking error of the test bench and cross-coupling between forces and bending moments. The effect of the tracking error and cross-coupling on the dynamic response of the test article was quantified using multibody simulation. The tracking error was found not to significantly change the dynamic response of the drivetrain. The experimental and simulation results are used to recommend acceptance criteria for the tracking error when replicating dynamic loads.

The main focus of the recommended spatial accuracy tests for the multi‐leaf collimators (MLC) is calibration of the leaf position along the movement direction and overall alignment to the radiation isocenter. No explicit attention was typically paid to the alignment of the leaves from the opposing banks in the direction orthogonal to movement. This paper is a case study demonstrating that verification of such alignment at the time of acceptance testing is prudent. The original standard MLC (SMLC) on an MRIdian MRI‐guided linac (ViewRay Inc., Mountain View, CA, USA) was upgraded to a high‐speed MLC (HSMLC), which is supposed to be mechanically identical to the SMLC except for the higher drive screw pitch. The results of the end‐to‐end IMRT tests demonstrated unacceptable dosimetric results exemplified by an average and maximum ion chamber (IC) point dose error in the high‐dose low‐gradient region of 2.5 ± 1.4% and 4.6%, respectively. Before the upgrade, those values were 0.3 ± 0.7% and 0.9%, respectively. An exhaustive analysis of possible failure modes eventually zeroed in on the average misalignment of about 1 mm in the Y (along the couch) direction between the right and left upper MLC banks. The MLC was replaced, reducing the Y‐direction misalignment to 0.4 mm. As a result, the average and maximum IC dose‐errors became acceptable 1.0 ± 0.7% and 1.6%, respectively. Simple film and/or chamber array tests during acceptance testing can easily detect Y‐direction misalignments between opposing leaves banks measuring a fraction of a mm at isocenter. Left undetected, such misalignment can cause nontrivial dosimetric consequences.

Wafer test is carried out after integrated circuits (IC) fabrication to screen out bad dies. In addition, the results can be used to identify problems in the fabrication process and improve manufacturing yield. However, the wafer test itself may induce defects to otherwise good dies. Test-induced defects not only hurt overall manufacturing yield but also create problems for yield learning, so the source problems in testing should be identified quickly. In the wafer acceptance test process, dies are probed in a predetermined order, so test-induced defects, also known as site-dependent faults, exhibit specific patterns that can be effectively captured in test paths. In this paper, we analyze characteristics of test-induced defect patterns and define features that can be used by machine learning algorithms for the automatic detection of test-induced defects. Therefore, defective dies caused by the wafer test can be retested for yield improvement. Test data from six real products are used to validate the proposed method. Several machine learning algorithms have been applied, and experimental results show that our method is effective to distinguish between test-induced and fabrication-induced defects. On average, the prediction accuracy is higher than 97%.

The established group chain acceptance sampling plans (GChSP-1) functions with five acceptance criteria, while the modified group of chain acceptance sampling plans (MGChSP-1) operates with three acceptance criteria. Since the acceptance criteria affect the performances of the sampling plans, therefore, this article suggests a balanced approach by introducing a new group of chain acceptance sampling plans (NGChSP-1), where it functions with four acceptance criteria. The NGChSP-1 is developed by using minimum angle method which caters for producer’s and consumer’s risks. The generalized exponential distribution is selected as the lifetime distribution and the simulation for the NGChSP-1 is conducted at various values of design parameters using the Scilab programming. The finding shows that the optimal number of groups and the corresponding smallest theta for NGChSP-1 are smaller compared to those for the GChSP-1. For illustration purposes, the NGChSP-1 is then applied to real data of air conditioning equipment.

Hydrogen exchange-mass spectrometry (HX-MS) is widely recognized for its potential utility for establishing the equivalence of the higher-order structures of proteins, particularly in comparability and similarity contexts. However, recent progress in the statistical analysis of HX-MS data has instead placed an emphasis on significance testing to identify regions of proteins where there are significant differences in HX between two or more protein states. In the cases involving assessment of similarity or equivalence of the higher-order structure of different protein samples (e.g., biosimilars), significance testing of HX-MS data is unsuitable. To meet this need, we have adapted the univariate two one-sided test (TOST) equivalence testing method for HX-MS data. Equivalence acceptance criteria were determined using maximum deviations from randomized resampling of truly equivalent samples to define hybrid equivalence criteria (maximum deviation of true equivalents, MDTE). Application of the TOST-MDTE test on differential HX-MS measurements of wild-type and mutated maltose-binding proteins demonstrates that the equivalence testing method was fit-for-purpose. Three infliximab biosimilars (Remsima, Renflexis, and Inflectra) were found to be equivalent to their Remicade reference product based on differential HX-MS measurements, while 5% deglycosylated NIST mAb was not statistically equivalent to the unmodified NIST mAb reference.

To date, in the mass production of medicines both in pharmaceutical companies and in pharmacies, more and more attention is paid to the practice of process validation. Validation is a key condition for the implementation of Good Manufacturing (GMP) and Pharmacy (GPP) practices, the standards of which are mandatory for medicines worldwide and in Ukraine. The aim of the work – validation of the technological process of preparation extemporaneous hymoding cream with hyaluronic acid in order to obtain documentary evidence of effective reproduction of the preparation of this medicine. The study design is based on research on the development of dosage form technology, analysis of the impact of critical manufacturing points and evaluation of their impact on the final quality of the cream, taking into account the requirements of GPP. The object of validation is the technological process of preparation hymoding cream with hyaluronic acid. The validation procedure was performed on 3 experimental batches of the medicine. In order to check and optimize the selected technological process of preparation hymoding cream in pharmacies, its validation was carried out. According to the calculated quantities of the components of the studied cream, as well as the identified critical parameters, three batches of the medicine of 100.00 g were developed. On the series of cream, the optimization of technological parameters, testing of critical parameters for all planned stages of production with the definition of eligibility criteria and validation scheme was carried out. Acceptance criteria for all critical parameters were determined during the optimization of technology on batches of the studied medicine. The general risk assessment was carried out at the stage of pharmaceutical development according to the procedure «identification – analysis – risk assessment» to determine the scheme of validation work on batches of the medicine. During the technological process, critical indicators were checked and appropriate forms were filled out. A study on the validation of the technological process of preparation hymoding cream with hyaluronic acid in pharmacies was performed. Documentary evidence of effective reproduction of the manufacture of this medicine has been obtained. A comprehensive analysis of the developed manufacturing process makes it possible to identify critical control points that minimize the occurrence of possible risks in the manufacture of the investigated medicine. According to the results of the research, it can be concluded that the developed cream with hyaluronic acid meets the requirements of State Pharmacopoeia of Ukraine in all quality indicators, which allows to recommend it for use in dermatology.

Материалы статьи посвящены актуальной теме – повышению качества посева семян зерновых культур. В ней отмечено, что известные конструкции лаповых и дисковых сошников имеют значительные тяговое сопротивление, образуют широкую борозду, которую затруднительно заделать, не обеспечивают качественное копирование рельефа поля. Всё это негативно сказывается на равномерности распределения семян зерновых культур, как по длине рядка, так и по глубине заделки. Наиболее перспективным направлением повышения качественных показателей работы посевного агрегата, является оснащение зерновых сеялок комбинированными сошниками. В статье приведено краткое описание и результаты приемочных испытаний зерновой сеялки С-7,2ПМ4 с новыми комбинированными однодисковыми сошниками, разработанными ФГБОУ ВО Пензенский ГАУ совместно с АО «Радиозавод» г. Пенза. Приемочные испытания проводились ФГБУ «Поволжская государственная зональная машиноиспытательная станция» (г. Кинель Самарской обл.) на полях ООО АПК «Комсомолец» Кинельского района Самарской области в соответствии с ГОСТ 31345-2017 «Техника сельскохозяйственная. Сеялки тракторные. Методы испытаний» [1-6]. При этом была проведена агротехническая, энергетическая, эксплуатационно – технологическая и экономическая оценка сеялки. В ходе приемочных испытаний было установлено, что комбинированные однодисковые сошники с копирующими колесами и сеялка С-7,2ПМ4 в целом надежно выполняет технологический процесс. При рабочей скорости агрегата 7,5-10,0 км/ч количество семян, заделанных на заданную глубину составляет 87,2-89,2 %, тяговое сопротивление находилось в пределах 9,45-9,47 кН, что соответствует тракторам тягового класса 1,4, затраты труда составляют 0,27 чел. ч/га, при этом совокупные затраты денежных средств при стоимости сеялки 1241,67 тыс. руб., составили 885,69 руб./га. The article is devoted to the current issue – improving the quality of planting seeds of grain crops. It is noted that the major designs of shovel and disc coulters have significant traction resistance, form a wide furrow, which is difficult to close, and do not provide high-quality following of the field relief. All this negatively affects the uniformity of the distribution of grain seeds, both along the length of the row and the depth of placement. The most promising direction for improving the quality indicators of the sowing unit is to equip grain planters with combined coulters. The article presents a brief description and results of acceptance tests of the S-7,2PM4 (С-7,2ПМ4) grain planter with new combined single-disc coulters developed by the Penza State Agrarian University in cooperation with JSC (AO) "Radiozavod", Penza. Acceptance tests were conducted by the Federal State Budgetary Institution "Volga MIS" (Kinel, Samara Oblast) in the fields of LLC Agro-Industrial Complex "Komsomolets" Kinelsky district of the Samara Oblast in accordance with GOST 31345-2017 "Agricultural machinery. Tractor seeders. Test methods" [1-6]. At the same time, an agrotechnical, energetic, operational, technological and economic assessment of the seeder was carried out. During acceptance tests, it was found that the combined single-disc coulters with gauge-wheels and the S-7,2PM4 (С-7,2ПМ4) seeder reliably perform the technological process. At the working speed of the unit - 7.5-10.0 km/h, the number of seeds covered at a given depth was 87.2-89.2 %, the traction resistance was within 9.45-9.47 kN. It corresponds to tractors of the traction class 1.4. Labour costs were 0.27 work h/ha, while the total cost of money at the price of the seeder - 1241.67 rubles, amounted to 885.69 rubles/ha.

This paper describes the development of two experimental school library information systems for Malaysian schools. The results of a user study, conducted using different sets of questionnaire for both types of schools indicated that students in general, borrowed books from the library by browsing the shelves. Students seldom used the catalogue card for searching and only a small percentage reported that they were able to find the books successfully using the catalogue card. Based on the findings, a conceptual model of the prototype automated catalogue was developed - Virtual Library for use in primary schools, and ELIS for secondary schools. Both systems are divided into two main modules, the Administrator and the User module. User acceptance test showed that the majority of students found the systems user friendly. Students were also successful in the search tasks given. A high majority described the graphical user interface to be attractive and simple. This indicates the feasibility of using the systems for school libraries in Malaysia.

Gross alpha-beta measurement is a worldwide applied technique to determine activity concentration in drinking water. Laboratories have implemented standard methods where standard sources measurements and routine methods are applied to achieve good analytical results. Proficiency testing is among the most used methods to assess the accuracy of the analytical data produced by laboratories, as this also represents a requirement for laboratories which have ISO 17025 and a quality assurance system implemented. The results presented in this paper show the performance of two laboratories for proficiency tests organized by IAEA, to which SALMROM laboratory and Personal Dosimetry Monitoring Laboratory (LDPM) have participated in 3 years. The feedback from the final reports from IAEA reports demonstrates the performance of the laboratories where 17 out of 18 results pass the acceptance criteria. Only one reported result has a warning which means that it did not pass all acceptance criteria. The results served as a basis to improve the laboratory analysis and to optimize accuracy measurements. The overall results of the PTs point out the reliability and traceability of the systems used for drinking water measurements.

The German Aerospace Center DLR is the German research institute with approximately 8000 employees in 20domestic locations. Among the aerospace research priorities of the German Aerospace Center DLR it includes also energy, safety and transport. DLR is institutionally supported by federal and state governments. Next funding sources arise in the context of third-party funds business (contract research and public contracts and subsidiaries). Main activities of the test center Lampoldshausen are testing of ARIANE's main and upper stage engines in the frame of ESA contracts. In the last years the test center of the DLR in Lampoldshausen has grown strongly over more than 30 %, so that the number of employees is actually of about 320. The testing department is mainly responsible for rocket combustion testing according to customer requirements. Two kinds of test facilities are operated, sea level test facilities and the altitude simulation test facilities. In addition to the DLR's growth also the activities of the industrial partner Ariane Group has been elevated so that actually nearly 600 employees are present on site Lampoldshausen. The management of the site in relation to safety and security requires special measures with special respect to the presence of more people inside the testing area in order to guarantee trouble-free and safe experimental operation onsite the DLR´s test plants. In order to meet with the future needs of continuing growth, the security and safety requirements have to be adopted. This report gives comprehensive outlook information about future possible scenarios of our coming tasks. Main driving force for future requests is the evolution of the rocket ARIANE. The new test position P5.2 has been erected to perform the qualification of the new upper stage with the VINCI engine. This project is very complex. In parallel to the construction work and acceptance testing actual running operation processes requires special procedures related to the overall safety of the test center. The site of Lampoldshausen with its test and supply facilities is subject to the restrictions of the German law Bundesimissionsschutzgesetz (derived from the European SEVESO-III directive) and its relevant ordinances, especially the Hazardous Incident Ordinance. Because of the complex framework effort which guarantees safety and security, Lampoldshausen has invested in people and processes in order to respect the restrictions of all relevant laws and ordinances as well as to guarantee the protection of people and the environment. Therefor a very special Master plan has been developed, with the goal to rearrange the complete testing area in order to be able to divide the area in certain sectors (testing range, technology and bureau) so that future testing enterprises will not affect almost free testing activities inside the site as it is in the present status. The paper provides comprehensive information related to the applied innovations including detailed background facts linked to the established safety and security standard applications.

Purpose Online and offline software products can estimate the maximum skin dose (MSD) delivered to the patient during interventional cardiology procedures. The capabilities and accuracy of several skin dose mapping (SDM) software products were assessed on X-ray systems from the main manufacturers following a common protocol. Methods Skin dose was measured on four X-ray systems following a protocol composed of nine fundamental irradiation set-ups and three set-ups simulating short, clinical procedures. Dosimeters/multimeters with semiconductor-based detectors, radiochromic films and thermoluminescent dosimeters were used. Results were compared with up to eight of 10 SDM products, depending on their compatibility. Results The MSD estimates generally agreed with the measurements within ± 40% for fundamental irradiation set-ups and simulated procedures. Only three SDM products provided estimates within ± 40% for all tested configurations on at least one compatible X-ray system. No SDM product provided estimates within ± 40% for all combinations of configurations and compatible systems. The accuracy of the MSD estimate for lateral irradiations was variable and could be poor (up to 66% underestimation). Most SDM products produced maps which qualitatively represented the dimensions, the shape and the relative position of the MSD region. Some products, however, missed the MSD region when situated at the intersection of multiple fields, which is of radiation protection concern. Conclusions It is very challenging to establish a common protocol for quality control (QC) and acceptance testing because not all information necessary for accurate MSD calculation is available or standardised in the radiation dose structured reports (RDSRs).

This paper presents two metrics designed to measure the data uniformity of acceptance tests in FitNesse and Gherkin notations. The objective is to measure the data uniformity of acceptance tests in order to identify projects with lots of random and meaningless data. Random data in acceptance tests hinder communication between stakeholders and increase the volume of glue code. The main contribution of this paper is the implementation of the proposed metrics. This paper also evaluates the uniformity of test data from several FitNesse and Gherkin projects found on GitHub, as a means to verify if the metrics are applicable. First, the metrics were applied to 18 FitNesse project repositories and 18 Gherkin project repositories. The measurements taken from these repositories were used to present cases of irregular and uniform test data. Then, we have compared the notations from FitNesse and Gherkin in terms of projects and features. In terms of projects, no significant difference was observed, that is, FitNesse projects have a level of uniformity similar to Gherkin projects. However, in terms of features and test documents, there was a significant difference. The uniformity scores of FitNesse and Gherkin features are 0.16 and 0.26, respectively. These uniformity scores are very low, which means that test data for both notations are very irregular. Thus, we can infer that test data are more irregular in FitNesse features than in Gherkin features. The evaluation also shows that 28 of 36 projects (78%) did not reach the minimum recommended measure, i.e., 0.45 of test data uniformity. In general, we can observe that there are still many challenges in improving the quality of acceptance tests, especially in relation to the uniformity of test data.

Purpose Existing phantom-less quality assurance (QA) platforms does not provide patient-specific QA for helical tomotherapy (HT). A new system, called TomoEQA, is presented to facilitate this using the leaf open time (LOT) of a binary multi-leaf collimator, as measured by an exit detector. Methods TomoEQA was designed to provide measurement-based LOTs based on detector data and to generate a new digital imaging and communication in medicine (DICOM) dataset that includes the measured LOTs for use by secondary check platforms. To evaluate the system, 20 patient-specific QAs were performed using the program in Mobius3D software, and the results were compared to conventional phantom-based QA results. Results From our assessment, most of the differences between the planned and measured (or calculated) data, excluding one case, were within the acceptance criteria comparing with those of conventional QA. Regarding the gamma analysis, all results considered in this study were within the acceptance criteria. In addition, the developed system was performed for a failed case and showed approximately the same trends as the conventional approach. Conclusions TomoEQA could perform patient-specific QAs of HT using Mobius3D and provide reliable patient-specific QAs results by evaluating point dose errors and 3D gamma passing rates. TomoEQA could also distinguish whether an intensity-modulated radiation therapy plan failed or not.

The human body’s reaction to various therapeutic medications is critical to comprehend since it aids in the appropriate construction of automated decision support systems for healthcare. Healthcare Internet of Things (IoT) solutions are becoming more accessible and trusted, necessitating more testing before they are standardized for commercial usage. We have developed an activity diagram based on the Unified Modeling Language (UML) to represent acceptability testing in IoT systems. The activity flow graph is used to extract all of the necessary information by traversing the activity flow diagram from start to finish, displaying all its properties. In this paper, a test case is generated to compute the type of diabetes using blood sugar test results, estimate the kind of diabetes, and the probability that a person would get diabetes in the future. We have demonstrated how these test cases can function using a telehealth care case study. First, we offer a high-level overview of the topic as well as a design model working diagram. The test case creation method is then outlined using the activity diagram as a guide.

One of the main problems in operation of wells equipped with installations of electric centrifugal pumps is determining the technical condition of submersible electrical equipment and preventing its failures. Among the various approaches to solving this problem, one can single out a method for determining the technical state of an installation of electric centrifugal pumps using a complete customizable mathematical model of the installation, including a model of a submersible induction motor. This article discusses an approach to determining and restoring the necessary parameters for tuning a submersible induction motor model based on the data given in the submersible induction motor test report. The main aim of the research is to develop a methodology for restoring the parameters of the equivalent circuit for submersible induction motor on the basis of typical data contained in the acceptance test report. Methods. The proposed approach is based on the combined use of a tunable dynamic model of a squirrel-cage induction motor and a differential evolution algorithm. The actual solution to determine the parameters of submersible induction motor damage is reduced to solving the global optimization problem, i. e. to the problem of finding the global (best) minimum of a function. Results. The authors have developed an approach for restoring the parameters of the submersible induction motor equivalent circuit, which allows setting the values of the equivalent circuit parameters for the submersible induction motor, acceptable for practice, according to the test results; the performance of the developed identification approach was tested using global optimization methods and mathematical modeling of submersible induction motors; the obtained estimates are stable for all parameters of the equivalent circuit except for the parameter of the mechanical subsystem.

Dengan misi menyediakan data statistik berkualitas, data yang disediakan oleh Badan Pusat Statistik harus mempunyai total survey error yang kecil. Total survey error mencakup sampling error dan nonsampling error, dengan nonsampling error yang berperan lebih besar. Dalam survei atau sensus yang dilaksanakan oleh BPS, nonsampling error ini sangat dipengaruhi oleh kualitas petugas lapangan yang direkrut oleh BPS dan biasa disebut dengan istilah “mitra statistik”. Untuk mendapatkan calon mitra statistik yang berkualitas baik perlu melalui proses uji penilaian atau uji kelayakan menjadi seorang calon mitra.

During the model-based software testing process, test cases are generated from modeled requirements to conduct acceptance testing. However, existing approaches generate erroneous test cases, lack full coverage criteria and prototype tools. Therefore, the aim of this research is to develop an approach capable of reducing erroneous test case generation based on full coverage criteria and a prototype tool. The method employed was to develop a parser to extract information from the XMI file of a modeling diagram where a tree is constructed and a traversal operation executed on the nodes and edges to generate test cases. The results obtained from the proposed approach showed that 97.35% of the generated test cases were precise and comprehensive enough to conduct testing because 99.01% of all the nodes and edges were fully covered during the traversal operations.

Aluminium outfitting is widely used in offshore platforms owing to its anti-corrosion ability and its light weight. However, various standards exist (ISO, NORSOK and EN) for the design of handrails used in offshore platforms, and different suppliers have different criteria. This causes great confusion for designers. Moreover, the design load required by the standards is not clearly defined or is uncertain. Thus, many offshore projects reference previous project details or are conservatively designed without additional clarification. In this study, all of the codes and standards were reviewed and analysed through prior studies, and data on variable factors that directly and indirectly affect the handrails applied to offshore platforms were analysed. A total of 50 handrail design load scenarios were proposed through deterministic and probabilistic approaches. To verify the proposed new handrail design load selection scenario, structural analysis was performed using SACS (offshore structural analysis software). This new proposal through deterministic and probabilistic approaches is expected to improve safety by clarifying the purpose of the handrails. Furthermore, the acceptance criteria for probabilistic scenarios for handrails suggest considering the frequency of handrail use and the design life of offshore platforms to prevent excessive design. This study is expected to prevent trial and error in handrail design while maintaining overall worker safety by applying a loading scenario suitable for the project environment to enable optimal handrail design.

Relevant international instrument transformer standards specify internal arc testing to prove the transformer behavior under internal fault conditions. However, the test is defined in a way that does not recognize that it is possible to limit and reduce the total fault energy. For such instances, testing, as currently defined, is mostly inapplicable. The purpose of this paper is to address this issue by presenting a testing sequence that is applicable for verifying the behavior of transformers with sectioned active parts that contain energy-limiting features. Furthermore, the acceptance criteria for the successful completion of the test are also introduced. Every step of the proposed test sequence is discussed in detail and presented on a 145 kV inductive transformer, selected specifically for this purpose. This paper is a part of a continuous broad research with the aim of developing and specifying adequate routine, type and special testing sequences for qualifying paper-oil insulation systems that limit internal arc energy, with the aim of improving the performance of such systems and introducing test methods and criteria that exceed the practices of current standards.

This work aimed to elaborate 2 formulations of tambaqui sausages, smoked freshness and cuiabana, and to perform their sensory evaluation. After preparation, the pasta was embedded in a casing and stored under refrigeration until the moment of smoking, in the case of freshness, and subsequently the analyzes were carried out. Acceptance, purchase intention and preference tests were carried out, with the participation of 49 IFAM / CMZL tasters. Cuiabana showed better results in all analyzes, with values of 4.52 for the acceptance test, 4.44 for the purchase intention, and 65.3% in the preference test. The freshness obtained, respectively, the values of 4.31, 4.33, 34.7%. Despite the differences, it can be said that both formulations have been accepted and are commercially viable.

The current condition experienced by the XYZ Polyclinic is that there is no application built to simplify the service process contained in the polyclinic so that all service processes are still manual. An example is the calculation of the number of drugs that are in and out of use. This calculation takes a long time, is prone to errors in accounting, and consumes many papers. To solve this problem, we develop an application to recap drugs. The drug recapitulation application is based on a website with the WebML method using the CodeIgniter framework and MySQL database. The application produces the result in the form of a PDF file of the drug recapitulation report per month and day. As a security feature, the monthly drug recapitulation report results include a digital signature as proof of authentication, integrity, and anti-denial. The application built has been tested using web testing methods and user acceptance testing to be applied.

The results of experimental studies of the static characteristics of the speed controller of a free turbine of the pump-controller of the HP-3 type, intended for a turboshaft gas turbine engine of the TВ3-117 type, are presented. When conducting acceptance tests of engines on hydraulic brake units, malfunctions are recorded, which manifest themselves as steady fluctuations in the speed of the turbocharger and free turbine rotors in the area of the free turbine regulator. Checking the pump-regulators according to the manufacturer's acceptance test report does not reveal the cause of this malfunction. As a result of the analysis of experimental static characteristics, it was revealed that the actual static characteristics of real regulators are very different from each other even within the acceptable values of the acceptance test protocol and have characteristic features: different values of statism, hysteresis, as well as deviations from linearity - breaks and fractures. Small statism of the regulator (large gain) reduces the margin of stable operation of the automatic control system, which contributes to the development of self-oscillations, and at certain values of the dynamic parameters of the engine, the control process may become unstable. The hysteresis of the static characteristic of the regulator plays an important role in vibration damping. It should be positive, since it is conditiones by the frictional forces in the hydraulic drive of the main metering needle. Therefore, a zero or negative hysteresis of the static characteristic of the regulator indicates a defect in the unit, which is confirmed by a tendency to self-oscillation. Non-linearity of the static characteristic of the regulator can lead to unsatisfactory operation of the automatic control system by the engine. It is shown that the static characteristic of the speed controller of a free turbine is a confirmation of the quality of manufacture or repair of pump-regulators of the HP-3 type during acceptance tests.

Structures are designed using current seismic design codes which are mostly based on Force-Based Design approach. The aim of the work is to implement the Performance-Based Seismic Design (PBSD) approach in concrete buildings. PBSD, which is a new concept in seismic design of structures, is a reliable approach capable of providing more detailed information on the performance levels of both structural and non-structural elements. Methods. In this study Performance-Based Seismic Design has been utilized on reinforced concrete irregular frame. In order to do this pushover analysis was done. Story drift ratios were chosen as deformation limits to define the performance levels for specific earthquake hazard levels. The results of this study show that Performance-Based Seismic Design gives a structure with better seismic load carrying capacity, thereby achieving the objective of performance as well as economy. It is also possible to conclude that PBSD obtained by above procedure satisfies the acceptance criteria for immediate occupancy and life safety limit states for various intensities of earthquakes.
