Abstract:
Rapid and accurate industrial inspection to ensure the highest quality standards at a competitive price is one of the biggest challenges in the manufacturing industry. This paper shows an application of how a Deep Learning soft sensor application can be combined with a high-resolution optical quality control camera to increase the accuracy and reduce the cost of an industrial visual inspection process in the Printing Industry 4.0. During the process of producing gravure cylinders, mistakes like holes in the printing cylinder are inevitable. In order to improve the defect detection performance and reduce quality inspection costs by process automation, this paper proposes a deep neural network (DNN) soft sensor that compares the scanned surface to the used engraving file and performs an automatic quality control process by learning features through exposure to training data. The DNN sensor developed achieved a fully automated classification accuracy rate of 98.4%. Further research aims to use these results to three ends. Firstly, to predict the amount of errors a cylinder has, to further support the human operation by showing the error probability to the operator, and finally to decide autonomously about product quality without human involvement.

Abstract:
The construction industry has embraced digitisation and industrialisation in response to the need to increase its productivity, optimise material consumption and improve workmanship. Additive manufacturing (AM), more widely known as 3D printing, has driven substantial progress in these respects in other industries, and a number of national and international projects have helped to introduce the technique to the construction industry. As with other innovative processes not covered by uniform standards, appropriate assessments and testing methodologies to control the quality of the 3D-printed end products, while not obligatory, are advisable. This article shows that regulation is not an obstacle to the use of an innovative product, such as 3D printing, by proposing quality-control tests and an assessment methodology, in the understanding that standardisation ensures the viability of a technology. The information, including the methods and results, is based on the authors’ experiences in the development of three research projects pertaining to 3D printing. This paper also discusses whether the performance of the materials used in 3D printing could be superior to traditional ones.

Abstract:
The aim of this review is to present the factors influencing the mechanical properties of 3D-printed oral dosage forms. It also explores how it is possible to use specific excipients and printing parameters to maintain the structural integrity of printed drug products while meeting the needs of patients. Three-dimensional (3D) printing is an emerging manufacturing technology that is gaining acceptance in the pharmaceutical industry to overcome traditional mass production and move toward personalized pharmacotherapy. After continuous research over the last thirty years, 3D printing now offers numerous opportunities to personalize oral dosage forms in terms of size, shape, release profile, or dose modification. However, there is still a long way to go before 3D printing is integrated into clinical practice. 3D printing techniques follow a different process than traditional oral dosage from manufacturing methods. Currently, there are no specific guidelines for the hardness and friability of 3D printed solid oral dosage forms. Therefore, new regulatory frameworks for 3D-printed oral dosage forms should be established to ensure that they meet all appropriate quality standards. The evaluation of mechanical properties of solid dosage forms is an integral part of quality control, as tablets must withstand mechanical stresses during manufacturing processes, transportation, and drug distribution as well as rough handling by the end user. Until now, this has been achieved through extensive pre- and post-processing testing, which is often time-consuming. However, computational methods combined with 3D printing technology can open up a new avenue for the design and construction of 3D tablets, enabling the fabrication of structures with complex microstructures and desired mechanical properties. In this context, the emerging role of computational methods and artificial intelligence techniques is highlighted.

Abstract:
Additive manufacturing (3D Printing) has become a promising manufacturing method as it can produce parts in a flexible and efficient way, especially for very irregular parts. However, during the printing process, the material experiences a great temperature change from the melting temperature to room temperature; this causes high thermal strains and induces distinct deformations which degrade the quality of the printed parts, especially in metal 3D printing. In order to reduce possible problems and find possible solutions, a prior evaluation by simulation is often adopted. Nevertheless, since the 3D printing process generates parts in a layer-by-layer way, the analysis model should also be layer-by-layer arranged and used with a layer-by-layer based analysis process to simulate the layer-by-layer additive printing; otherwise, the simulation may not match the real behavior. In order to meet these requirements, a new meshless method is proposed to match the situations and handle these problems. As a meshless method, the modeling is not constrained by the element distribution. In addition, the analysis model generated with the proposed method can be arranged in a layer-by-layer way and combined with the proposed layer-by-layer analysis scheme, so it can then match and simulate the printing processes. Furthermore, the layer-by-layer arranged models can be automatically created, directly based on the STL (STereo-Lithography) geometry model, which is a de facto standard in the 3D printing industry. This makes the proposed approach more straightforward and efficient. To validate the proposed method, two parts with holes inside have been printed and simulated for comparison. The results show a good agreement. In addition, a highly irregular part has also been simulated to demonstrate the effectiveness and efficiency of this proposed method.

Abstract:
Проблема повышения точности контроля в процессе производства различных печатных изделий не теряет своей актуальности в связи с совершенствованием как технологий изготовления самих изделий, так контрольно-измерительной техники и методов контроля. Поскольку нанесение красочного изображения, выполняющего информационную функцию, на печатное изделие способами печатания осуществляется на достаточно высокой скорости, то широко используемый метод визуального контроля малоэффективен, применим выборочно, не позволяет обеспечить требуемую точность. Следствием этого является брак или ухудшение качества напечатанных изображений на печатных изделиях. Показано, что действующие методы контроля, регламентированные стандартами, не отвечают требованиям для выпуска конкурентоспособной на современном рынке продукции В работе проанализированы стандартные и запатентованные методы контроля показателей качества, нанесенного на печатное изделие изображения способами печатания. Отмечены направления их модернизации и разработки новых объективных методов контроля, что возможно осуществлять только за счет использования современных систем с применением программых продуктов, разработанных под конкретный объект контроля, способствующих интеграции процессов измерения и анализа информации для стабилизации технологического процесса печати. Предложен метод контролякрасковосприятия, который основан на методах математического и гармонического анализа. Ввиду отсутствия стандарта, разработан алгоритм контроля показателя укрывистость. Оценка и контроль укрывистости в данном алгоритме базируется на методах математической статистики. Определение и контроль показателей красковосприятия, укрывистость осуществляется с помощью разработанных программ для ЭВМ, что позволяет не только существенно сократить время контроля, но и повысить его точность. Providing that both current processing techniques and supervisory instruments is updating, the problem of the accuracy quality parameters continues to be relevant for printing industry. Due to high-speed processes of the printed items manufacturing the current visual-based monitoring techniques can be thought of as low informative, selective applied resulted in accuracy decreasing at lot inspections. The most current monitoring methods regulated by standards are low-efficient at the moment. Both standard and patented quality monitoring techniques for printed images monitoring were analyzed. The listed techniques upgrading trends and points of the novel objective ones developing based on specified software hardware integration of measurement and information analysis procedures aimed at the operational process stabilization are noted. The ink trapping monitoring technique based on both mathematical and Fourier analysis is proposed. As long as the standard procedure is deficient, the algorithm of covering power control based used mathematical statistics approaches was developed. The monitoring is carried out by the developed software.

Abstract:
To expend the printed color gamut is the most important area for today’s print quality. Conventional wide gamut printing technologies utilize six or seven colors. However, these processes increase the complexity and the cost. Therefore, the four-color wide gamut inks are becoming the major development in Taiwan’s printing industry. This study is focused on the print performance study of the four-color wide gamut inks in the domestic market that are complied with the RoHS regulations. In this study Tung-Ming and K+E wide gamut process inks were tested for their print performance. The press control was to comply ISO12647-2 specifications. The test forms were printed on both type 1 and type 2 papers that specified in ISO12647-2. The normal process ink set was also printed to compare with those wide-gamut color ink sets. The result shows that the both wide-gamut ink sets have reached color gamut larger than the ISO12647-2. In this study shows that the domestic normal process ink set can comply the international standard, and the developing wide gamut ink also reach the standard. However, the color characteristics and printability have to test before using these wide gamut color ink sets. With the optimized process control and color management system, the four-color wide gamut inks can produce the best color result on paper.

This research report is based on a case study. It follows up on the research of a previous study by Muregerera (1996). His thesis was compiled in order to develop a model for a world-class manufacturing organization. For his case study, he chose Omnigraphics. Although his focus was on world class manufacturing principles, he did address Omnigraphics prior to the organization receiving ISO 9000 certification through the SASS. This research report therefore looks at the transformation that Omnigraphics went through, from an organization without a formal quality management system, to one with a functional quality management system. Chapter one defines quality management systems and the benefits of a formal quality management system. Current research is discussed in chapter two together with the benefits and requirements of the ISO system. Chapter three addresses the challenges, which Omnigraphics faced prior to ISO 9000 implementation and the changes that occurred once this organization was certified to ISO 9001. A comprehensive survey was done to identify the actual benefits that suppliers and customers see in dealing with an ISO 9000 listed organization. Chapter four looks at the participants of the survey as well as the questions posed. Chapter five gives the results of the survey in a graphical format as well as an interpretation of the results. The research report also focuses on the new revision of the ISO 9000 series and this is addressed in chapter six. The report closes by reviewing the research and looking at the future of the ISO 9000 series.

Abstract:
This investigation attempts to examine the influences of validation on pharmaceutical processes especially at a new manufacturing facility that has to meet international requirements, and fulfil a cost effective business strategy. At Aspen Pharmacare, a pharmaceutical organisation, there are two manufacturing facilities situated adjacent to each other, one new and one old. The new facility creates ideal opportunities to supply products to local and international markets. The investigation compares legal requirements from local and international regulatory authorities. Validation and qualification practices as well as the problems encountered during the different phases are discussed. Particular attention is given to the validation approach at the new Aspen facility. Problems and proposed solutions relating to the design review, installation, operational, and performance qualification are discussed. Validation of analytical methods for cleaning analysis, cleaning validation of equipment, and optimisation of some tablet manufacturing processes are described. Statistical evaluations of analytical results are included to find the optimum conditions for integrating new personnel with new processes and equipment. A business model reviews the cost of non-conformances of the enalapril maleate 10 mg tablets manufactured at the two manufacturing facilities. Finally the dissertation proves that validation is not only a regulatory requirement but that it also provides benefits such as adding value to the business, and ultimately reducing the cost of medicines.

Abstract:
Software implementation projects struggle with the delicate balance of low cost, on-time delivery and quality. The methodologies and processes used to create and maintain a quality software system are expensive to deploy and result in long development cycle-time. However, without their deployment into the software implementation life-cycle, a software system will be undependable, unsuccessful. The purpose of this research is to identify a succinct set of software implementation success criteria and assess the key independent constructs, activities, carried out to ensure a successful implementation project. The research will assess the success of a software implementation project as the dependent construct of interest and use the software process model (methodology) as the independent construct. This field research involved three phases: (1) criteria development, (2) data collection, and (3) testing of hypotheses and discriminant analysis. The first phase resulted in the development of the measurement instruments for the independent and dependent constructs. The measurement instrument for the independent construct was representative of the criteria from highly regarded software implementation process models and methodologies, e.g., ISO9000, Software Engineering Institute's Capability Maturity Model (SEI CMM). The dependent construct was developed from the categories and criteria from the Delone and McLean (1992) MIS List of Success Measures. The data collection and assessment phase employed a field survey research strategy to 80 companies involved in internal software implementation. Both successful and unsuccessful software implementation projects (identified by the Delone/McLean model) participated. Results from 165 projects were collected, 28 unsuccessful and 137 successful. The third phase used ANOVA to test the first 11 hypotheses and employed discriminant analysis for the 12th hypothesis to identify the "best set" of variables, criteria, that discriminate between successful and unsuccessful software implementation projects. Twelve discriminating variables out of 67 were identified and supported as significant discriminators between successful and unsuccessful projects. Three of the 11 constructs were found not to be significant investments for the successful projects.

ENGLISH ABSTRACT: In the face of increasing competition, Business Schools increasingly have to evaluate the quality of the service that they offer to current and prospective students. The most significant factor affecting an organisation's performance is the quality of its products and services in relation to the products and services of competitors. Measurement of service quality is a function of customer satisfaction, which in tum is based on a perception of how the service conforms to prior expectations thereof. A widely accepted method of quality assurance used in industry is ISO 9000 certification. For academic institutions the de facto method of providing confidence in the quality of the education they offer is through academic accreditation. The University of Stellenbosch Business School (USB) is unclear - in the light of its academic accreditations - of the benefits to be derived from implementing ISO standardisation within the organisation. The iso 9000 series is a set of quality standards, of which ISO 900 I: 2000 is one, which is primarily concerned with the quality management process. It deals with what the organisation does to enhance customer satisfaction by meeting customer and applicable regulatory requirements, and to continually improve the organisations performance in this regard. It is important to note that compliance with ISO standards is not intended to guarantee the quality of a product or service, it is however intended to provide confidence in the processes which produced or delivered the product or service. In evaluating the applicability of ISO 9000 in the service industry, it is concluded that there is little difference from how its standards and guidelines apply in manufacturing to how they apply in service industries. The USB is found to have implemented an extensive quality management system in order to attain various academic accreditations, most notably EQUIS accreditation. Thus from an academic perspective there would be little to gain from USB implementing ISO 9001: 2000, even though the standard is perfectly suited for academic environments. Where advantages would most likely be realised is in the peripheral business and support functions of the USB.
AFRIKAANSE OPSOMMING: In die aangesig van toenemende mededinging moet bestuurskole gereeld die kwaliteit van diens wat hulle aan huidige en voomemende studente bied, evalueer. Die mees veelseggende faktor in 'n organisasie se prestasie is hoe die kwaliteit van sy produkte en dienste vergelyk met die van sy mededingers. Die meet van die kwaliteit diens wat 'n organisasie lewer is 'n funksie van die tevredestelling van kliente, wat op sy beurt weer gebaseer is op insig tot die wyse waarop die diens ooreenstem met die oorspronklike verwagtinge daarvan. ISO 9000 sertifikasie word algemeen aanvaar in industrie as 'n betroubare maatstaf waarteen kwalitieit gemeet word. Vir akademiese instellings is die de facto metode om vertroue te wek in die kwaliteit van die opleiding wat hulle aanbied, deur middel van akademiese akkreditasie. Vir die Universiteit van Stellenbosch Bestuurskool (USB) is dit in die lig van hulle akademiese akkreditasie onduidelik wat die voordele verbonde aan die implementering van ISO standaardisering binne die organisasie sou wees. Die reeks ISO 9000 is 'n stel kwaliteitstandaarde, waarvan ISO 900 I: 2000 een is, en is hoofsaaklik gemoeid met die proses van kwaliteitsbestuur. Dit bemoei hom met die stappe wat 'n organisasie neem om klientebevrediging te bevorder deur die bereiking van die vereistes van beide sy kliente en die toepasbare voorskrifte. Dit is belangrik om daarop te let dat 'n onderworpenheid aan ISO standaarde geensins die bedoeling het om die kwaliteit van 'n produk of diens te waarborg nie - die oogmerk is egter om vertroue te wek in die prosesse wat die produk of diens veroorsaak of gelewer het. Deur die toepasbaarheid van ISO 9000 in die diensbedryfte evalueer, is dit vasgestel dat daar inderdaad min verskil is tussen die wyse waarop hierdie standaarde en riglyne van toepassing is in die vervaardigingsektor en hoe dit toegepas word in diensbedrywe. Dit is vasgestel dat USB 'n verreikende kwaliteitsbestuursisteem in werking het om verskeie akademiese akkreditasies te bekom, veral die EQUIS akkreditasie. Die gevolgtrekking is dat daar vanuit 'n akademiese oogpunt min rede is vir USB om ISO 900 I: 2000 te implementeer, selfs al is hierdie standaard goed van toepassing op 'n akademiese omgewing. Waar dit tot sy beste voordeel toegepas kan word, is in die omliggende sake- en ondersteuningsfunksies van USB.

Thesis (MTech (Business Administration))--Cape Peninsula University of Technology, 2017.
The purpose of this study was to determine the impact of four High Performance Work Practices (HPWPs) on project performance in selected construction companies in Cape Town, South Africa. The four HPWPs comprised: recruitment and selection (RS); performance appraisal (PA); training and development (TD); and compensation system (CS). The study employed a positivist philosophy utilizing the survey method to collect data from 70 employees who were drawn from a select group of multi-project construction companies in Cape Town, South Africa. The respondents comprised employees who worked as project team members and line staff/ administrative staff. Non-probability sampling procedure in the form of convenience sampling technique was used for the selection of five (5) construction organisations in Cape Town, South Africa. Probability sampling procedure in the form of stratified sampling technique was employed in the selection of the respondents to complete the questionnaire.Collected data was captured and analyzed using the Statistical Package for the Social Sciences (SPSS) version 24. The main research question of the study was: What is the relationship between the four HPWPs and project performance? The results indicate that CS has a weak positive relationship with project performance, whereas TD, PA and RS have weak negative relationships with project performance. It also emerged that there are other factors that significantly affect project performance other than the HPWPs investigated.The results of this study are significant because they provide a unique view of the work environment that has been insufficiently examined. Also, very few studies have focused on the above four universal HPWPs, which this study was earmarked for. The results that are obtained from this study significantly add to the overall body of knowledge pertaining to theories and their application in HRM, project performance and multi-project environments issues.

Abstract:
During the 1980´s, before the industrial globalization took place, some recommended practices or standards were used to provide the calibration services for inspection, measurement and testing equipment (IM&TE) in America. Before the ISO Standards were used to provide quality services or to be ISO accredited, the calibration laboratories were using the MIL-STD-45662A. While the ISO standards became the most applicable references for quality systems certification and for the accreditation of the calibration laboratories the ISO/IEC-17025 became the standard that should be met for the accreditation. Since the beginning of the calibration services, the calibration certificates contained information about the status of the instrument, depending of its type and the method used to calibrate the instrument, also some other requirements were included in the certificates, like the uncertainty and the evidence of the proficiency tests that the laboratory had to provide. With the technological advancement in electronics, the instruments became more sophisticated and accurate. The use of computers and dedicated software for calibration developed new calibration methods. Industry 4.0 includes a wide variety of sensors to monitor different parameters along the process or to measure quality specifications, most of those sensors are electronically integrated to the process control. Metrology 4.0 is giving a new way of calibration services applying the AI and IoT.

Abstract:
The American Society for Mechanical Engineers (ASME) is developing and implementing a Nondestructive Examination (NDE) and Quality Control (QC) personnel qualification and certification program (ANDE). In keeping with ASME development of codes and standards the NDE program will be assembled by industry experts and administered centrally by ASME. A new ASME standard recognized by ANSI is being developed as the core of the program and will be based upon industry best practices. The total program is a significant paradigm change from the traditional employer based and other central qualification and certification programs, the new standard will include features such as the Systematic Approach to Training, Job Task Analysis and Qualification Cards to direct the development of training and experience. The program was designed to improve the skill level and consistency amongst NDE practitioners and will use the performance-based approach including psychometric practices in the development of both written and practical demonstration examinations. This paper will primarily focus on the development of the standard and its salient features.

Abstract:
Digital Printing has been established as one of the most rapidly evolving printing processes since its first introduction in 1982. In the years that followed, digital printing became the one significant new technology for print media production. Digital printing is continuously changing the print media landscape. Although, DP creates structural changes in production workflow and processes, it lacks in terms of print standardization, compared to offset printing for example, where consistent aim values and guidelines apply by means of ISO 12647-2. This drawback basically depends on two factors, which are interrelated. Firstly, there are many different technologies that are used in digital printing, and, each of them shows substantial difference in printing technology, substrates, data preparation, process control and image quality requirements. Secondly, compared to conventional printing, some digital printing technologies are still developing. After all, digital printing is versatile and variable in every way and cannot be standardized under a single standard. A research on the digital printing technologies, processes and workflows is needed, to determine if a print specifications and quality controls (among them color management), can be applied in Digital Printing, and if possible, to which segment. Since color is very important to printing, especially in packaging and marketing applications, the print evolution demands for matching colors across technologies, substrates, materials and colorants. This paper intends to reveal the present status regarding Digital Printing Standardization. The question posed is whether standards can be applied and in which segments of digital printing either as technology or print sector (commercial decoration, packaging). Within the paper, an analysis of the current industrial typical guidelines ranging from data creation all the way to printing will be made. Guidelines that are determined either by the manufactures of the digital printing machines, or by Institutes, such as FOGRA are reviewed for output process control and colour fidelity. As such, this paper can be regarded as a first attempt to preview the basis where standardization for digital printing processes can be developed.

Abstract:
Abstract Fused Deposition Modelling (FDM) provides opportunities for new development in numerous areas. Z-directional anisotropic strength caused by weak inter-layer bonding has been recognized as the reason for limited industry adoption of FDM. This paper aims to investigate increasing the Z-directional strength of Acrylonitrile Butadiene Styrene (ABS) using a temperature controlled print environment. The ambient temperature during printing was increased to reduce heat transfer from the print, thereby encouraging more polymer chain inter-diffusion between layers. Dogbone specimens were printed at ambient print temperatures between 24.8°C and 71.2°C and tensile tests were performed. A thermal camera was used to identify heat loss in the FDM process. Ultimate tensile strength was found to increase by a maximum of 104% compared to open enclosure printing. A stylus profiler and scanning electron microscopy were used to compare the quality of the inter-layer bonds, suggesting that additional polymer inter-diffusion occurred at hotter ambient temperatures. A weak positive relationship was found between ambient air temperature and inter-layer part strength. Further experimentation could provide scope to determine an ideal ambient print temperature that is likely to be dependent on print settings and the printer used.

Full text
Abstract:
Historically, pipeline operators have tended to place more weight on inline inspection tool specifications than on the inherent design and reporting capabilities of the service providers themselves. While internal collection of integrity data is very important, it’s imperative that vendors, also, have high levels of expertise and effective quality control systems in place to successfully analyze exceedingly high volumes of inspection data. The quality of inspection information is vital to assessing if a pipeline is fit for purpose now and/or into the future. Integrity managers attempting to reduce overall operating risk by making decisions based on inaccurate or poor quality reporting are in fact exposing their networks to greater safety and financial risk. Recognizing these risks and that inline inspection (ILI) is an overall system that needs to be formally qualified, operators and ILI service providers have collaborated to develop several international standards. The most recent is the umbrella API-1163 industry consensus standard, which is now being widely adopted, primarily in USA. This standard provides requirements and recommended practices for qualification of the entire ILI process. Two companion standards: ASNT In-line Personnel Qualification and Certification Standard No. ILI-PQ and NACE Recommended Practice In-Line Inspection of Pipelines RP0102 combine to address specific requirements for personnel who operate and analyze the results of ILI systems. In Europe, the Pipeline Operators Forum (POF) has, also, established specific requirements for ILI reporting processes and data formats. However, these standards do not define how operators and vendors must meet these requirements. To follow will be a story about how an ILI service provider embraced a holistic approach to address these standards’ requirements, in particular in the areas of data analysis, reporting, and dig verification due to their significant importance in assuring the final quality of its deliverables. A key outcome desired will be to provide operators with greater insight into what best practices and technologies ILI service providers should have embraced and invested in to insure reliable service delivery.

In 2018 12th International Pipeline Conference. American Society of Mechanical Engineers, 2018. http://dx.doi.org/10.1115/ipc2018-78299.

Full text
Abstract:
Heat treated pipeline fittings (principally elbows, tees, and reducers) require careful process control. For example, furnace temperature, placement of the fittings in the furnace, transfer time to quenching tank, adequacy of quench or tempering time can all impact the fittings’ mechanical properties if not done properly. In recent years, the National Energy Board (NEB) became aware of instances of quenched and tempered (Q&T) pipe and fittings having mechanical properties that did not meet Canadian Standards Association (CSA) or similar standards, being installed on pipeline systems under NEB and other regulatory bodies’ jurisdiction. In 2013, a pipeline rupture occurred on an NEB-regulated pipeline. Although failure to meet mechanical specifications was not the cause of the incident, the investigations revealed that there were fittings installed on the pipeline with yield strength of less than Specified Minimum Yield Strength (SMYS). The NEB undertook further investigations to determine if this low yield issue might indicate a systemic problem. In the cases examined, contrary to the recorded information in the Material Test Reports (MTRs), not all fittings met the specified mechanical properties requirements, and this was due to inadequate controls in the Quality Assurance Programs (QAPs) of different stakeholders. It is also important to note that MTR results based on a coupon test may not always reflect the properties of each fitting produced following that process. The NEB has taken several actions in order to address this potential issue including: - Issuing industry-wide Safety Advisories - Issuing Orders to all companies under its jurisdiction - Commissioning a third party to investigate and write a technical paper on this issue - Hosting a technical workshop to facilitate broad dialogue between various stakeholders (using the technical paper as a seed document) In this paper, the authors first review the manufacturing process of Q&T fittings. Then case studies are discussed involving four instances of nonconforming fittings. Lastly the authors propose solutions for different stakeholders to effect improvement in Quality Assurance (QA) of pipeline fittings. The authors also recommended enhancement of applicable clauses in related standards and initiation of several research and development (R&D) projects.

Full text
Abstract:
API 5L allows skelp-end welds (SEWs) in finished pipes with some restriction on their position relative to the pipe ends. However, the overall acceptance of SEWs by the pipeline industry is spotty. For large diameter pipes, there could be one SEW for every five to seven joints of pipes. Therefore, allowing SEWs in finished pipes offers meaningful economic advantages to both pipe suppliers and purchasers when the quality of the SEWs can be assured. A joint industry project (JIP) was formed to develop uniformly acceptable inspection and test plans (ITPs) for SEWs. The JIP members included the five linepipe manufacturers and six pipeline operators. The ITPs were developed through two parallel processes: (1) fitness-for-service analysis of the SEWs under a variety of loading conditions expected in the entire service life of a pipeline, and (2) consensus building based on the best practice and quality control protocols. The JIP group reviewed the suitability of existing QA procedures for SEWs and sought to provide users further assurance by developing supplemental QA/QC procedures. The ITPs contain additional provisions to supplement the requirements of the accepted industry standards, such as API 5L and CSA Z245.1. They incorporated specific quality control measures that address concerns in certain perceived weak points of SEWs, including the effects of coil-end properties, weld quality at T-joints, and open-root forming of the partial-penetration ID weld. This paper summarizes the deliberation and recommended resolution of several key issues related to the perceived quality concerns of SEWs. A companion paper covers the fitness-for-service analysis of SEWs [1]. The project group, led by respective organizations of the authors, is working with API 5L committee to adopt some of the recommendations in the future revisions of API 5L.

Full text
Abstract:
Increasingly stringent emissions standards have accounted for continuing increases in the end-user cost of a modern diesel engine, most of which due to complex and expensive emissions after treatment devices such as selective catalytic reduction (SCR), which relies on urea to be injected into a catalyst bed to remove nitrogen oxide emissions from the engine exhaust. Prior to the current emissions standards the diesel industry had been able to meet NOx levels by reducing the combustion temperature in the engine via charge gas dilution, through cooled EGR. Although successful in reducing emissions, large levels of EGR have undesirable effects on oil quality, engine longevity, overall efficiency and warranty returns. There is also a limit to the efficacy of EGR in lowering NOx emissions such that at the current EPA mandated 0.2g/kWh, it is no longer sufficient. Another well-known NOx mitigating solution has been the introduction of water into the diesel engine combustion chamber. This has been known to decrease peak combustion temperatures and decrease NOx emissions but usage so far has been limited to stationary and marine applications due to the requirement of a separate water tank and thereby a two-tank system. Combustion of hydrocarbon fuels produces between 1.35 and 2.55 times their mass in water. As an enabler to water injection, this paper will also demonstrate a technique where the exhaust is first cooled via a heat exchanger, and then passed through a cyclonic separator to separate heavier liquid particles from the exhaust gas flow. Through vortex separation over 100% of the burned fuel mass can be recovered as liquid water from the exhaust. A prototype system was developed and installed on a VW TDI diesel engine. Tests were conducted with and without after-treatment and results have been discussed in subsequent sections. The water was then utilized in conjunction with EGR to control NOx emissions, allowing a reduction of over 97%, thus achieving the 0.2g/kWh standard with no after treatment.

Abstract:
Abstract An emerging trend in smart manufacturing of the future is robotic additive manufacturing or 3D printing which introduces numerous advantages towards fast and efficient printing of high-quality customized products. In the case of the construction industry, and specifically in large-scale settings, multi-robotic additive manufacturing (i.e., adopting a team of 3D printer robots) has been found to be a promising solution in order to overcome the existing size limitations. Consequently, several research efforts regarding the development and control of such robotic additive manufacturing solutions have been reported in the literature. However, given the increasing environmental concerns, establishing novel methodologies for energy-efficient processing and planning of these systems towards higher sustainability is necessary. This paper presents a novel framework towards energy-efficient multi-robotic additive manufacturing and describes the overall challenges with respect to the energy efficiency. The energy module of the proposed framework is implemented in a simulation environment. In addition, a systematic approach for energy-aware robot positioning is introduced based on the novel concept of reciprocal energy map. The reciprocal energy map is established based on the original energy map calculated by the energy module and can be used for identifying the low energy zones for positioning and relocation of robots during the printing process.

In ASME 2007 InterPACK Conference collocated with the ASME/JSME 2007 Thermal Engineering Heat Transfer Summer Conference. ASMEDC, 2007. http://dx.doi.org/10.1115/ipack2007-33971.

Full text
Abstract:
In current technology, white light generation from a light emitting diode (LED) can be achieved by combining the lights from three fundamental colors, namely, red, green and blue (RGB), of LEDs or by coating a phosphor layer onto the surface of a LED chip. The first method involving the RGB color mixing technique requires a complicated electrical circuit design for the control of light intensity and uniformity on the three different colors of LEDs and hence increases the costs of manufacturing. The second method is implemented by coating a layer of yellow phosphor on a blue LED chip for white light illumination. The quality of generated white light heavily depends on the packing density, the thickness and the uniformity of the phosphor coating. There have been some coating methods available in the industry. Each one of them has its own pros-n-cons. In the present study, a new yellow phosphor coating method by screen-printing on blue LED arrays is developed. Compared with conventional coating methods, this screen-printing method is considered relatively simple and rather effective. The newly developed method and the results of prototyping are introduced in this paper in detail.
