Abstract:
Abstract The paper explores the possibility of using a number of nickel alloys in multilayer coatings to decrease nickel consumption and preserve the functional effect of the coating. The following is proved by the graphical calculation technique using experimental data on the galvanic properties of the multilayer coating parts. Nickel-iron, nickel-phosphorus and nickel-tin alloy can be applied as a lower coating layer rather than semi-shiny, shiny or composite nickel. It is advisable to use a nickel-iron alloy as the middle (second) layer, and the concentration of iron depends on the composition of the first and third layers. If a nickel-iron alloy is applied as the material of the first layer, then the second layer may be semi-shiny (Ns-sh) or shiny (Nsh) nickel. The substitution of nickel layers for nickel alloys allows to considerably (about 10%) decrease the cost of a multilayer coating, while the protective properties are remaining the same. The application of the same nickel-containing alloys as single-layer anticorrosive coatings shows a lower level of protective properties.

Abstract:
Rapid prototyping technology implemented quite actively for all types and types of production. Its application reduces the influence of human factor on quality of a product but it also require the operator that knows this field and have some skills of handling machine. These technologies are also used to create models and visual functional prototypes, which can recreate the developed process and test the individual steps to prove its efficiency. The laboratory equipment that was made in Freiberg University of Mining and Technology allows to produce metal microspheres and shell (0,5 – 3 mm). Modernization of this equipment was proposed by creating a prototype of a mechatronic system that would show the requirements to the device and its capabilities. Creation of a device prototype is a transitional point from a laboratory layout to production equipment that works with high performance and repeatability. The device can operate under vacuum and inert gas that allows to work not only with model materials such as tin, zinc, alloy rose eutectic alloys based on bismuth and tin but also with structural materials, such as aluminum, magnesium and their alloys. Individual parts of the functional prototype was created by rapid prototyping technology (MJM, FDM and milling) of the polymers.

Abstract:
The status of Mg alloy application, and then some key issues limiting their applications and the corresponding accesses were briefly discussed. It was supposed that development of new alloys with high performance and low cost, investigating advanced forming technology, and development of credible and effective surface modification technologies and related equipment were the urgent tasks in present. Correspondingly, three aspects of researches were carried out. (1) A new alloy with high strength and elongation, but low RE and Zn contents, named ZW21, was invented. (2) Semisolid ingots of AZ91D, AM60 and ZW21 alloys available for thixoforming were prepared. Thixoforming increased the ultimate tensile strength of AZ91D alloy by 20% compared with permanent mould casting. (3) A new kind of micro arc oxidation equipment with a capacity of treating 6m2 surface was developed and has been used to treating motorcycle hub of magnesium alloy.

Abstract:
Bellows are widely used as parts in industrial machinery such as ships, valves, automotive, semiconductor equipment, flow and pressure sensors, and even in aircraft. Due to the recent depletion of conventional fossil fuels, natural liquified petroleum is increasingly demanded as an alternative energy, which in turn increases the demand for bellows on LNG ships. As the material used the bellows of LNG ships, the STS316L and INCOLOY 825 alloy, resistant to low-temperature embrittlement and corrosion, are used. STS316L is low-carbon stainless steel with a carbon content of less than 0.03%, preventing intergranular corrosion by welding work and maintaining its toughness and strength at a low temperature. In addition, Ni-Fe-Cr-based INCOLOY 825 alloy, containing Mo, Cu and Ti, is an alloy material resistant to general local corrosion in various atmospheres. INCOLOY 825 alloy is widely used for the creation of chemical processing equipment and in pollution-treatment facilities, oil and gas reduction equipment, acid manufacturing plants, pickling plants, nuclear fuel reprocessing and radioactive waste treatment facilities as well as in the bellows of LNG ships. Furthermore this material maintains good mechanical properties across a wide range of temperatures from ultra-low temperatures up to temperature approaching 500 °C. In this study, to assess its quality as a LNG ship bellows material, the STS316L and INCOLOY 825 alloy, used at an ultra-low temperature, the optimal welding conditions were established and its formability was analyzed by conducting an Erichsen test.

Abstract:
In a high competitive market, the development of new alloys, new applications, price pressure and increases in product forces quality wire manufacturers to ask for increased mechanical characteristics without losing conductivity. As a particular example, development of new copper alloys such as CuZr, CuSn, CuMg and CuAg have been developed for automotive cables. Continuous extrusion is currently the most prevalent manufacturing technology in terms of chemical composition, mechanical properties and electrical properties, resulting in the production of high quality rods. However, continuous casting has good potential to also be adapted to the mass production of various copper alloy wires. Comparison of the continuous casting process to other thermal methods such as continuous extrusion highlighted that, in general, the mechanical properties of continuous cast materials are lower than that of material from thermomechanical methods. However, continuously cast alloys rods are cheap to produce and simple to manufacture. So, the key aims of this research were (a) to increase the understanding of the solidification behaviour of some industrially important continuously cast non-ferrous alloys, (b) to define an increased range of alloys and downstream processing techniques which could be performed using continuous casting technology, (c) to determine improved continuous casting process validation capabilities and (d) to define new capabilities in terms of casting equipment. The majority of this PhD thesis was focused on improving the current continuous casting technologies and development of casting capability of a range of copper and non-copper alloys. The analysis in this PhD thesis illustrated that the metallurgical and mechanical properties of components mainly produced by continuous casting are acceptable, and that this method could be a replacement production method for materials such as lead alloys and various copper alloy rod, e.g. CuMg and CuAg. However, in the case of Deoxidized High Phosphorus (DHP) copper tubes, the performance of the as-cast material was significantly lower than that of from extrusion or planetary rolling process. This PhD thesis also makes comment on the parameters controlling the solidification process in order to improve the quality of as cast alloys rods/tubes. Using specific casting parameters, a significant difference based on tensile strength and elongation percentage has been illustrated, and it was found that these parameters could improve the mechanical properties of continuously cast copper rods and tubes. This significant difference is as a result only of the change in casting parameters, with no difference in the chemical composition of the material, or the general method of production. These parameters were (1) water flow rate, (2) casting speed, (3) pull distance, (4) melt temperature, (5) cleanout cycle, (6) continuous casting direction and (7) super-cooler size. The new knowledge created and understanding gained during the course of this research improved the company’s capability in the marketplace, enabling it to supply equipment with improved competitive capabilities and the potential to enter new markets, leading to sales growth in existing sectors and significant longer-term growth into new technically challenging application areas.

Abstract:
Magnesium alloys have been widely explored as potential biomaterials, but several limitations to using these materials have prevented their widespread use, such as uncontrollable degradation kinetics which alter their mechanical properties. In an attempt to further the applicability of magnesium and its alloys for biomedical purposes, two novel magnesium alloys Mg-Zn-Cu and Mg-Zn-Se were developed with the expectation of improving upon the unfavorable qualities shown by similar magnesium based materials that have previously been explored. The overall performance of these novel magnesium alloys has been assessesed in three distinct phases of research: 1) analysing the mechanical properties of the as-cast magnesium alloys, 2) evaluating the biocompatibility of the as-cast magnesium alloys through the use of in-vitro cellular studies, and 3) profiling the degradation kinetics of the as-cast magnesium alloys through the use of electrochemical potentiodynamic polarization techqnique as well as gravimetric weight-loss methods. As compared to currently available shape memory alloys and degradable as-cast alloys, these experimental alloys possess superior as-cast mechanical properties with elongation at failure values of 12% and 13% for the Mg-Zn-Se and Mg-Zn-Se alloys, respectively. This is substantially higher than other as-cast magnesium alloys that have elongation at failure values that range from 7-10%. Biocompatibility tests revealed that both the Mg-Zn-Se and Mg-Zn-Cu alloys exhibit low cytotoxicity levels which are suitable for biomaterial applications. Gravimetric and electrochemical testing was indicative of the weight loss and initial corrosion behavior of the alloys once immersed within a simulated body fluid. The development of these novel as-cast magnesium alloys provide an advancement to the field of degradable metallic materials, while experimental results indicate their potential as cost-effective medical devices.

Full text
Abstract:
Roman military equipment has traditionally been studied from a typological perspective based on a linear concept of change. Whilst Roman alloys have been analysed scientifically and general studies on them have been published, analysis of military equipment has been scarce and mostly secluded as part of excavation reports of individual sites. Scientific analysis though, can provide independent ways of studying military equipment. It can answer questions about production and distribution of the raw materials and finished objects and is capable of informing on reasons for technological choices (the intention of obtaining determinate colours, for example), and identification of military units. A total of 216 copper-alloy military objects from the British sites of South Cadbury Castle, Ham Hill, Usk, Carlisle, Chester and Kingsholm, and the German site of Kalkriese were selected for obtaining metallurgical characterisation: chemical analysis at major, minor and trace element level and microstructural analysis to obtain fabrication history and identifying any plating. The analytical techniques employed were atomic absorption spectrometry (AAS), scanning electron microscopy with energy dispersive x-ray spectrometry (SEM-EDS), optical microscopy and multivariate statistics methods such as principal component analysis (PCA), discriminant analysis (DA) and multivariate analysis of variance (MANOVA). The aim of the project was to characterise the chemical and physical make-up of Roman military copper-alloy metalwork from the 1st century AD, with especial interest in the immediate post-conquest period. The results of the analysis show a difference between the Roman military equipment from British sites and the equipment from Kalkriese, based on trace element patterns. This difference can be explained by a large input of material into Britain that had been made in the years before AD43 in preparation for the conquest. Contrary to recent scholarship, and based on compositional and microstructural evidence, some lorica segmentata brass fittings seem to have been centrally produced. Primary brass and specific gunmetal compositions seem to be associated with the military and probably chosen primarily for their appearance and resemblance to gold, rather than for their mechanical properties. The possibility of mechanised production of brass is explored based on the brass ingot from Sheepen.

Full text
Abstract:
The work presented in this master thesis deal with the issue of quenching, investigation regarding different cooling rates and its effect on the material properties of aluminum alloy in the 6xxx series used for crash purposes in cars, such as crash boxes, beams and other crash relevant parts. Precipitation of Mg2Si due to different cooling rates affects the material properties such as crash performance, thus the aluminum alloy used is sensitive to different cooling rates. In order to perform tests with different cooling rates a cooling rig was constructed. In order to evaluate the different cooling rates both mechanical testing such as tensile test and 3-point bending test and compression test were performed. Also analyses with scanning electron microscope/energy-dispersive x-ray spectroscopy were performed to estimate grain boundary decoration of Mg2Si due to the different cooling rates. Furthermore LOM analyses were performed to evaluate if the experimental setup had any effect on material properties such as grain size. The constructed cooling rig produced different cooling rates with reliable repeatability as intended. Cooling rates between 130 ̊C/s and 20 ̊C/s were accomplished. Mg2Si occurred in all investigated test samples with various amounts. Higher cooling rates decreases the precipitation of Mg2Si to the grain boundaries, higher cooling rates also increased the bending angle achieved from the 3-point bending test. Furthermore, extensive solution heat treatment at elevated temperatures leads to grain growth.

SATAY allows not only the genome-wide mapping of genes required for growth in select conditions (such as genetic interactions or drug sensitivity/resistance), but also of protein sub-domains, as well as the creation of gain- and separation-of-function alleles. From strain preparation to the mapping of sequencing reads, we detail all the steps for the making and analysis of SATAY libraries in any S. cerevisiae lab, requiring only ordinary equipment and access to a Next-Gen sequencing platform.

Abstract. The article is devoted to the study of the wear intensity of elastic polymer-abrasive circles when processing the surfaces of parts made of high-strength aluminum alloys. Empirical dependencies of wear on cutting speed and tool deformation are obtained, on the basis of which method of tool deformation correction with long-term, continuous surface treatment is proposed. In practice, such a procedure is necessary due to the loss of process performance that occurs due to the reduction of tool deformation due to wear. The proposed technique allows to effectively control the finishing process as the tool is worn out.

Abstract:
Corrosion conditions in the Chemical and Oil and Gas Industries are such that equipment must withstand pressure and corrosion at high temperatures. Due to the fact that in many cases only the internal surface is exposed to corrosive attack, and so only that surface needs to be protected, savings on material costs can be achieved by taking advantage of the weld overlay technique. Weld overlay, through the choice of alloy, is selected to resist to the corrosive attack. Parent material can be selected based on the required strength at temperature. In recent years, highly corrosion resistant Nickel Chromium-Molybdenum Alloys have been developed to operate in the most severe corrosive environments. One of the recent developments in this family of materials, is Alloy 59 UNS N06059 that is replacing Hastelloy C-2000 UNS N06200 and Hastelloy C-22 UNS N06022. Nickel-Chromium-Molybdenum alloys are the most versatile nickel alloys, because they contain molybdenum, which protects against corrosion under reducing conditions, and chromium which protects against corrosion under oxidizing conditions. Wrought products produced from these alloys are processed to obtain a homogeneous austenitic grain structure. Weld overlay or weld deposit, due to the fundamental differences in processing compared to base material, result in a more heterogeneous metallurgical grain structure that in general shows however a good level of corrosion resistance. Weld or Weld overlay features are highly dependent on electric parameters, filler metal, technique, base material temperature, etc., and for this reason the general settings of the welding process need to be finalized and tested, with the intent of optimizing all these parameters in order to allow the best corrosion results. A research activity has been carried out by ALFA LAVAL OLMI to define a processes and parameters’ selection in order to obtain a weld deposit with a behavior as close as possible to wrought Alloy 59 base material.

Abstract:
Marine propulsion shafts typically are composites consisting of a strong, tough (often hollow) steel, bearing-surface sleeves, and corrosion-resistant cladding. Cladding alloys include Copper-Nickel alloys, austenitic “stainless steel” alloys, and Nickelbased Alloy 625. Cladding alloy weld metals are expensive as are the production costs of clad welding, weld inspection and rework. This paper describes collaborative efforts of a commercial Shaft Repair Facility (SRF) and a welding machine supplier to develop technical data supporting cleaner, more efficient and adaptable processes and equipment for corrosion-resistant alloy cladding. Reciprocating Wire Feed-Gas Metal Arc Welding (RWF-GMAW), specifically the proprietary Cold Metal Transfer (CMT) process, is presented a procedure-of-choice for corrosion-resistant weld cladding of Alloy 625 and of 300-series alloys on steel machinery.

Abstract:
The development of lightweight vehicles, in particular aluminum intensive vehicles, require significant manufacturing process development for joining and assembling aluminum structures. Currently, 5xxx and 6xxx aluminum alloys are being used in various structural applications in a number of lightweight vehicles worldwide. Various joining methods, such as MIG, Laser and adhesive bonding have been investigated as technology enables for high volume joining of 5xxx, and 6xxx series alloys. In this study, metal inert gas (MIG) welding is used to join 5754 non-heat-treatable alloy sheet products. The objective of this study is to develop optimum weld process parameters for non-heat-treatable 5754 aluminum alloys. The MIG welding equipment used in this study is an OTC/Daihen CPD-350 welding systems and DR-4000 pulse power supply. The factors selected to understand the influence of weld process parameters on the mechanical properties and metallurgy (weld penetration) include power input (torch speed, voltage, current, wire feed), pulse frequency, and gas flow rate. Test coupons used in this study were based on a single lap configuration. A full factorial design of experiment (DOE) was conducted to understand the main and interaction effects on joint failure and weld penetration. The joint strengths and weld penetrations are measured for various operating ranges of weld factors. Post weld analysis indicates, power input and gas flow rate are the two signficant factors (statistically) based on lap shear load to failure and weld penentration data. There were no 2-way or 3-way interaction effects observed in ths weld study. Based on the joint strength and weld penetration, optimum weld process factors were determined.

Abstract:
Abstract The generation and variation of forces necessary to achieve a training stimulus is often realized in sports and rehabilitation equipment by manually adjustable masses or by complex motor-brake systems. This leads to heavy and unwieldy systems, which cannot be used flexibly, and in addition to high costs. The main objective of this paper is to prove that pseudoelastic shape memory alloys (SMA) are potentially suitable for use in sports and rehabilitation equipment and offer additional value in the area of training flexibility combined with high training resistance. Therefore, the properties of pseudoelastic SMAs for this application were investigated. These multifunctional materials offer the potential for special elastic and sensory properties. The pseudoelastic effect is based on stress-induced martensite formation, which allows high elastic deformations. During this phase transformation, the mechanical stress passes through a plateau. The stress plateau can be moved by changing the temperature of the SMA. The determination of properties of pseudoelastic SMAs with different alloy compositions was carried out according to the specifications of “VDI 2248: Product Development with Shape Memory Technology”. With a functional model based on the material tests, which replaces a commercially available force clamping device, the monitoring of force, displacement and temperature changes can be realized by the integrated sensor technology. This paper presents the methodology, experiments and findings for the use of pseudoelastic SMAs in sport and rehabilitation devices. It concludes with prospects to commercial application.

Abstract:
Abstract The plasma transferred arc process continues to be the coating method of choice for the application of cobalt base alloys onto valve and valve trim. Although new applications have been developed over the years, the process remains largely associated with the application of high performance, highly alloyed powders for relatively small parts or small areas of large parts. The use of the plasma transferred arc process for large volume application has been limited by the robustness and performance characteristics of the equipment and the use of cobalt. A new plasma transferred arc system (power source, torch and process controller) has been developed which allows the application of powder metal alloys at deposition rates of up to 40 pounds per hour. In addition, there has been a development of new non-cobalt powder alloys with excellent mixed corrosion and wear resistance properties. These capabilities have rendered the process technically and economically viable for large and demanding applications in the mining, power utility and steel industries. The new PTA system and the recent developments in powder alloys will be discussed. Reference will be made to specific applications in target industries.

Full text
Abstract:
Background Early detection and identification of faulty greenhouse operation is essential, if losses are to be minimized by taking immediate corrective actions. Automatic detection and identification would also free the greenhouse manager to tend to his other business. Original objectives The general objective was to develop a method, or methods, for the detection, identification and accommodation of faults in the greenhouse. More specific objectives were as follows: 1. Develop accurate systems models, which will enable the detection of small deviations from normal behavior (of sensors, control, structure and crop). 2. Using these models, develop algorithms for an early detection of deviations from the normal. 3. Develop identifying procedures for the most important faults. 4. Develop accommodation procedures while awaiting a repair. The Technion team focused on the shoot environment and the Cornell University team focused on the root environment. Achievements Models: Accurate models were developed for both shoot and root environment in the greenhouse, utilizing neural networks, sometimes combined with robust physical models (hybrid models). Suitable adaptation methods were also successfully developed. The accuracy was sufficient to allow detection of frequently occurring sensor and equipment faults from common measurements. A large data base, covering a wide range of weather conditions, is required for best results. This data base can be created from in-situ routine measurements. Detection and isolation: A robust detection and isolation (formerly referred to as 'identification') method has been developed, which is capable of separating the effect of faults from model inaccuracies and disturbance effects. Sensor and equipment faults: Good detection capabilities have been demonstrated for sensor and equipment failures in both the shoot and root environment. Water stress detection: An excitation method of the shoot environment has been developed, which successfully detected water stress, as soon as the transpiration rate dropped from its normal level. Due to unavailability of suitable monitoring equipment for the root environment, crop faults could not be detected from measurements in the root zone. Dust: The effect of screen clogging by dust has been quantified. Implications Sensor and equipment fault detection and isolation is at a stage where it could be introduced into well equipped and maintained commercial greenhouses on a trial basis. Detection of crop problems requires further work. Dr. Peleg was primarily responsible for developing and implementing the innovative data analysis tools. The cooperation was particularly enhanced by Dr. Peleg's three summer sabbaticals at the ARS, Northem Plains Agricultural Research Laboratory, in Sidney, Montana. Switching from multi-band to hyperspectral remote sensing technology during the last 2 years of the project was advantageous by expanding the scope of detected plant growth attributes e.g. Yield, Leaf Nitrate, Biomass and Sugar Content of sugar beets. However, it disrupted the continuity of the project which was originally planned on a 2 year crop rotation cycle of sugar beets and multiple crops (com and wheat), as commonly planted in eastern Montana. Consequently, at the end of the second year we submitted a continuation BARD proposal which was turned down for funding. This severely hampered our ability to validate our findings as originally planned in a 4-year crop rotation cycle. Thankfully, BARD consented to our request for a one year extension of the project without additional funding. This enabled us to develop most of the methodology for implementing and running the hyperspectral remote sensing system and develop the new analytical tools for solving the non-repeatability problem and analyzing the huge hyperspectral image cube datasets. However, without validation of these tools over a ful14-year crop rotation cycle this project shall remain essentially unfinished. Should the findings of this report prompt the BARD management to encourage us to resubmit our continuation research proposal, we shall be happy to do so.

Abstract:
The article discusses the theory and methods of simulation training, its significance in the context of training specialists for areas where the lack of primary qualification is critical. The most widespread hardware and software solutions for the organization welders' simulation training that use VR- and AR- technologies have been analyzed. A review of the technological infrastructure and software tools for the virtual teaching-and-production laboratory of electric welding has been made on the example of the achievements of Fronius, MIMBUS, Seabery. The features of creating a virtual simulation of the welding process using modern equipment based on studies of the behavioral reactions of the welder have been shown. It is found the simulators allow not only training, but also one can build neuro-fuzzy logic and design automated and robotized welding systems. The functioning peculiarities of welding's simulators with AR have been revealed. It is shown they make it possible to ensure the forming basic qualities of a future specialist, such as concentration, accuracy and agility. The psychological and technical aspects of the coaching programs for the training and retraining of qualified welders have been illustrated. The conclusions about the significant advantages of VR- and AR-technologies in comparison with traditional ones have been made. Possible directions of the development of simulation training for welders have been revealed. Among them the AR-technologies have been presented as such that gaining wide popularity as allow to realize the idea of mass training in basic professional skills.

Abstract:
The article deals with the diagnosis of the formation of the information competence components of translators through testing. The use of testing to determine the level of formation of the information-thematic component of the information competence of translators is demonstrated. It has been established that one of the ways to form the information-thematic component of information competence in the aspect of studying terminology can be the use of thematic networks. The development of a thematic network is shown on the example of the thematic network “Electrical equipment”. The stages of test control, which are consistent with the logic of the organization of the educational process and the process of forming the information competence of the future translator according to the scheme of the developed thematic network, have been determined. These stages are the current, thematic, modular, final testing. The main types of test tasks are defined, the combination of which allows diagnosing the level of formation of the information-thematic component of students’ information competence. Criteria and principles for the selection of test tasks for each of the testing stages are proposed. The ratio of test tasks of different types and complexity at the determined testing stages has been developed. The results of an experimental study on the diagnosis of the formation of the information-thematic component of the information competence of future translators by applying the developed integrative testing system using the Moodle platform are presented.

Abstract:
[Extract from Executive Summary] This project, aimed at the development of a novel, automated mechanism for the collection of scallop stock data was a sub-part of the Scottish Inshore Fisheries Integrated Data Systems (SIFIDS) project. The project reviewed the state-of-the-art remote sensing (geophysical and camera-based) technologies available from industry and compared these to inexpensive, off-the -shelf equipment. Sea trials were conducted on scallop dredge sites and also hand-dived scallop sites. Data was analysed manually, and tests conducted with automated processing methods. It was concluded that geophysical acoustic technologies cannot presently detect individual scallop but the remote sensing technologies can be used for broad scale habitat mapping of scallop harvest areas. Further, the techniques allow for monitoring these areas in terms of scallop dredging impact. Camera (video and still) imagery is effective for scallop count and provide data that compares favourably with diver-based ground truth information for recording scallop density. Deployment of cameras is possible through inexpensive drop-down camera frames which it is recommended be deployed on a wide area basis for further trials. In addition, implementation of a ‘citizen science’ approach to wide area recording is suggested to increase the stock assessment across the widest possible variety of seafloor types around Scotland. Armed with such data a full, statistical analysis could be completed and data used with automated processing routines for future long-term monitoring of stock.

Roye, Thorsten. Unsettled Technology Areas in Deterministic Assembly Approaches for Industry 4.0. SAE International, August 2021. http://dx.doi.org/10.4271/epr2021018.

Full text
Abstract:
Increased production rates and cost reduction are affecting manufacturing in all sectors of the mobility industry. One enabling methodology that could achieve these goals in the burgeoning “Industry 4.0” environment is the deterministic assembly (DA) approach. The DA approach is defined as an optimized assembly process; it always forms the same final structure and has a strong link to design-for-assembly and design-for-automation methodologies. It also looks at the whole supply chain, enabling drastic savings at the original equipment manufacturer (OEM) level by reducing recurring costs and lead time. Within Industry 4.0, DA will be required mainly for the aerospace and the space industry, but serves as an interesting approach for other industries assembling large and/or complex components. In its entirety, the DA approach connects an entire supply chain—from part manufacturing at an elementary level to an OEM’s final assembly line level. Addressing the whole process of aircraft design and manufacturing is necessary to develop further collaboration models between OEMs and the supply chain, including addressing the most pressing technology challenges. Since all parts aggregate at the OEM level, the OEM—as an integrator of all these single parts—needs special end-to-end methodologies to drastically decrease cost and lead time. This holistic approach can be considered in part design as well (in the design-for-automation and design-for-assembly philosophy). This allows for quicker assembly at the OEM level, such as “part-to-part” or “hole-to-hole” approaches, versus traditional, classical assembly methods like manual measurement or measurement-assisted assembly. In addition, it can increase flexibility regarding rate changes in production (such as those due to pandemic- or climate-related environmental challenges). The standardization and harmonization of these areas would help all industries and designers to have a deterministic approach with an end-to-end concept. Simulations can easily compare possible production and assembly steps with different impacts on local and global tolerances. Global measurement feedback needs high-accuracy turnkey solutions, which are very costly and inflexible. The goal of standardization would be to use Industry 4.0 feedback and features, as well as to define several building blocks of the DA approach as a one-way assembly (also known as one-up assembly, or “OUA”), false one-way assembly, “Jig-as-Master,” etc., up to the hole-to-hole assembly approach. The evolution of these assembly principles and the link to simulation approaches are undefined and unsolved domains; they are discussed in this report. They must be discussed in greater depth with aims of (first) clarifying the scope of the industry-wide alignment needs and (second) prioritizing the issues requiring standardization. NOTE: SAE EDGE™ Research Reports are intended to identify and illuminate key issues in emerging, but still unsettled, technologies of interest to the mobility industry. The goal of SAE EDGE™ Research Reports is to stimulate discussion and work in the hope of promoting and speeding resolution of identified issues. SAE EDGE™ Research Reports are not intended to resolve the challenges they identify or close any topic to further scrutiny.

The costs of integrating reproductive health services: An example using syndromic management of STIs in family planning clinics in Zimbabwe. Population Council, 1999. http://dx.doi.org/10.31899/rh1999.1005.

Abstract:
Estimates from the United Nations Population Fund indicate that the costs of family planning (FP) and other reproductive health (RH) services are increasing and that it will be difficult for donors and countries to meet these costs. Many institutions delivering RH services operate significantly below their physical capacity to see clients, and much of the equipment required for expanding RH services may already be available for use. The marginal costs of adding infrastructure could be low. Many institutions have staff that are not fully occupied, and thus the staff necessary to expand RH services may also be in place. In this paper, we examine the cost implications for labor of expanding the provision of syndromic management services in FP clinics in Zimbabwe. Syndromic management of sexually transmitted infections allows health care workers to make a diagnosis without sophisticated laboratory tests because it is based on clinical syndromes and, in some cases, assessments of an individual patient’s risk for STI infection.

CAE Correlation of Sealing Pressure of a Press-in-Place Gasket. SAE Imposter, April 2021. http://dx.doi.org/10.4271/2021-01-0299.

Full text
Abstract:
The Press-in-Place (PIP) gasket is a static face seal with self-retaining feature, which is used for the mating surfaces of engine components to maintain the reliability of the closed system under various operating conditions. Its design allows it to provide enough contact pressure to seal the internal fluid as well as prevent mechanical failures. Insufficient sealing pressure will lead to fluid leakage, consequently resulting in engine failures. A test fixture was designed to simulate the clamp load and internal pressure condition on a gasket bolted joint. A Sensor pad using TEKSCAN equipment was used to capture the overall and local pressure distribution of the PIP gasket under various engine loading conditions. Then, the Sensor pad test results were compared with simulated CAE results from computer models. Through the comparisons, it is found that the gasket sealing pressure of test data and CAE data show good correlation for bolt load condition 500N when compared to internal pressure side load condition of 0.138 MPa & 0.276 MPa. Moreover, the gasket cross-sectional pressure distribution obtained by experimental tests and CAE models correlated very well with R2 ranging from 90 to 99% for all load cases. Both CAE and Sensor pad test results shows increase in sealing pressure when internal side pressure is applied to the gasket seal.
