Abstract:
This article highlights that electrical and mechanical engineers work together on products like cell phones; on the contrary, their software programs do not work like this anymore. Like cellular telephones and computers, all products made up of a combination of printed circuit boards and shaped materials like plastics require a rather tight degree of cooperation among mechanical engineers, electrical engineers, and finite element analysts. But today’s computer-aided design and finite element analysis technology is not advanced enough to let them work as skillfully together as they might. Engineers and analysts still need to translate their designs into a neutral file format in order to pass files between their different software systems, and much can be lost in translation. But a number of engineering software developers are refining products to break down some of those barriers. Electrical and mechanical engineers commonly use the software to work together on projects like the design of fan-cooled computer central processing units and how they are anchored using already-specified techniques that the mechanical engineer has programmed into the system.

Abstract:
This article discusses product data management PDM technology. This technology is a key to communicating with the suppliers and ensuring accurate design and manufacturing and allows designer and supplier to share documents and communicate back and forth. To meet the trend, a system that tracks design changes and allows engineer and designer to study them together becomes crucial. The vehicle maker wanted to standardize the way products are designed across both its truck and bus divisions. The technology is intended to help designers and engineers work more closely together, even if they are working in separate locations on unrelated parts of a truck or bus, and to keep track of changes in the highly customized part models. As a method of doing business changes, so does the technology needed to do that business. Although the answer is not in yet on PDM’s role in a changing marketplace, answers about how it fits into new supplier–customer business models are expected over the next few years.

Abstract:
This article reviews that the future belongs to machines built at molecular scales—if the tools to engineer them. Just as the steam engine sparked the industrial revolution of the 19th century, nanotechnology will likely ignite a new industrial revolution during the 21st century. Nanotechnology has the potential to impact all industries; the health care and computer industries are already capitalizing on it. New materials are being created that will affect everything from aerospace and energy to recreation and entertainment. Science is uncovering new technology almost daily, which will have a great impact on many aspects of society. These technologies are at various stages of development, but in the end, each spin-off product must withstand the test in the marketplace. The evaluation of each product will still be based on the same set of metrics as other products: performance, cost, risk or reliability, and availability. To satisfy these metrics, engineers will need analytical tools to make performance predictions, establish production costs and lifecycle economics, quantify the risk associated with new technologies, and satisfy a dynamic market.

Abstract:
Risk assessment is the systematic recording and evaluation of all factors in the work process that can cause occupational injuries, illnesses or health damage. It can identify the options, ways of preventing, eliminating and reducing risks.The risk assessment considers the work organization, work processes, raw materials and materials used in technological and work processes, personal protective equipment and equipment at work, as well as other elements that may cause risk of personal injury, health damage or illness of the employee.The primary objective of occupational risk assessment is the protection, safety and health of employees.Risk assessment helps to minimize the risk of employees being compromised during work process activities. It also helps to maintain the efficiency of the business activity.A risk assessment act is an act containing a description of the work process with an assessment of the risk of injury and / or damage to workplace health in the work environment and measures to eliminate or reduce risks in order to improve safety and health at work.This act determines the possible types of hazards and harms in the workplace, assesses the risk of injury at work or health damage of the employee, determines ways and measures to eliminate them, or reduce their risk to minimum.Mechanical engineers design machines and tools, organize their production and handle their exploitation. They are experts for propulsion engines, vehicles and vessels, process and power plants, load-bearing structures. As designers, they design a product or manufacturing process so it can best meet the requirements and functions they need. In a process of designing a product, they take available raw materials and available production technology, and if they design the production process, they are guided by the type of input material and processing technology. Mechanical engineers in manufacturing plan, manage and supervise the production of machinery and plant. They systematically test the manufactured components, because they depend on the efficiency, reliability and safety of the whole system. For quality assurance, they constantly carry out tests and measurements of input materials and finished products with measuring instruments.This work is based on an analysis of the position of a mechanical engineer in the company named "Flamma-Systems Ltd." based in Nis. The company employs mechanical engineers and it deals primary with manufacturing of high-power boilers for heating greenhouses and buildings. The main market for this company is Sweden.

Abstract:
Automated robot-based nanomanipulation is one of the key challenges in microsystem technology and nanotechnology, which has recently been addressed by a rising number of R&D groups and companies all over the world. Controlled, reproducible assembly processes at the nanoscale will enable high-throughput manufacturing of revolutionary products and open up new application fields. The ultimate goal of these research activities is the development of automated nanomanipulation processes to build a bridge between existing precise handling strategies for micro and nanoscale objects and aspired high-throughput fabrication of microsystems and nanosystems. Despite the growing interest in automated nanomanipulation, there is hardly any publication that treats this research in a coherent and comprehensive way. This paper is an attempt to provide the researcher with an overview of the most important trends and developments in this rapidly expanding technology. It also informs the practising engineer and the engineering student about automation at the nanoscale level as well as about the promising fields of application. The latter can be of a very different nature as nanohandling is strongly interdisciplinary in character. This paper offers a deeper insight into nanohandling aspects of carbon nanotubes.

Abstract:
Manufacturing and engineering companies around the world are building virtual products that can communicate across the barriers of time, distance, discipline, and culture. Interactive-product-simulation (IPS) technology complements the processes used to create three-dimensional geometry. IPS software leverages a company's investment in computer-aided design (CAD) design by providing earlier access to prototypes, faster updates than with physical models, enterprise-wide distribution of information in an easy-to-understand format, support for existing processes, and long-term value that extends beyond the finalization of product designs. IPS provides real-time interaction via the virtual product-a simulated version of the final functioning design that can include functional simulations, animations, mechanisms, and simulated humans or ‘manikins.’ IPS has many applications in the concept phase, where one of the most critical challenges for manufacturers is the economic evaluation and frequent review of multiple high-level concepts and configurations. PS enables engineers, manufacturing and maintenance staff, and even customers to visualize and operate complex virtual products so that they can improve the designs' manufacturability, ergonomics, and maintainability.

Full text
Abstract:
This article elaborates the design options that engineers have for low-volume productions. Designing complex products for low-volume production usually involves some degree of compromise. However, that does not mean that the available processes are going to be inadequate. By understanding the limitations of each process, an engineer can tailor the design to make great parts with low-volume techniques, for instance, by adding compliance features to reduce the need for tight tolerances, reinforcing the walls with ribs, or combining processes. While the enclosure may be best suited for cast urethane, other components may be better suited for machined aluminum and sheet metal to increase strength or to create a high-tolerance internal frame. Moreover, while it is likely that a product only has one enclosure, other components may qualify as high quantities. A designer can amplify the part count by making the left and right sides the same or by using the same part in multiple places. The principles of design for manufacture extend to all processes.

Abstract:
This article presents the technology of direct laser deposition. This technology is one of the most perspective new technologies. It allows realizing heterophase process during the manufacturing, in which the process of partial melting of the used powder is realized. The product is formed from a metal powder, which is supplied by a compressed gas-powder jet directly into the laser action zone. Ti-based alloys are interesting for many industrial areas, for example, engine systems, aircraft and shipbuilding, because of their corrosion resistance, low density and high strength. The influence of roughness on the mechanical properties of Ti-based products prepared by direct laser deposition was studied. It was found that the surface roughness distorts the values of the mechanical characteristics.

Abstract:

High demands are set on all equipment used in emergency service work, where small margins can be the distinguishing factor between life and death during a rescue operation. It is important that tools such as ladders quickly and easily can be dismounted from a vehicle and still satisfy the regulatory requirements for securing loads during transport. The existing solution for getting ladders down from the roof of a fire engine requires a large manual effort from the user in an ergonomically unsound posture.

In this degree project a new ladder holder is developed with focus on the user to solve the ergonomic problems and at the same time create a more compact design that can be adapted to several different types of ladders. After an initial pre-study with user-interviews and measurement of forces and distances a set of requirements was formulated that came to govern the project's direction. Creative methods were used to generate concepts that improved the function and through design solutions, calculations and testing in CAD a base for manufacturing of a new product was created.

The result is a completely new type of ladder holder that minimizes the user's manual effort and simplifies the securing of ladders in the holder. Measures have been taken to reduce material usage and manufacturing cost, while aiming for reliability and durability. Further development and construction of physical prototypes is needed before the new ladder holder can go into production.


Höga krav ställs på all utrustning som används vid räddningstjänstens arbete, då små marginaler kan vara skillnaden mellan liv och död under en utryckning vid olycka. Det är viktigt att verktyg såsom stegar snabbt och enkelt kan monteras av från ett fordon och samtidigt uppfyller lagkrav för säkring av last under färd. Den existerande lösningen för att få ned stegar från taket på en brandbil kräver en stor manuell kraftansträngning från användaren i en oergonomisk arbetsställning.

I detta examensarbete utvecklas en ny steghållare med användaren i fokus för att lösa de ergonomiska problemen och samtidigt skapa en mer kompakt konstruktion som kan anpassas till flera olika typer av stegar. Efter en inledande förstudie med användarintervjuer och mätning av krafter och avstånd formulerades en kravspecifikation som kom att styra projektets inriktning. Kreativa metoder användes för att generera koncept som förbättrade funktionen och via konstruktionslösningar, beräkningar och tester i CAD skapades ett tillverkningsunderlag för en ny produkt.

Resultatet är en helt ny typ av steghållare som minimerar användarens manuella kraft-ansträngning och förenklar låsningen av stegarna i hållaren. Åtgärder har tagits för att minska materialåtgång och tillverkningskostnad samtidigt som pålitlighet och hållfasthet har eftersträvats. Mer utveckling och konstruktion av fysiska prototyper är nödvändig innan den nya steghållaren kan gå i produktion.

Abstract:
Organic electronics is a platform for very low cost and high performance optoelectronic and electronic devices that cover large areas, are lightweight, and can be both flexible and conformable to irregularly shaped surfaces such as foldable smart phones. Organics are at the core of the global organic light emitting device (OLED) display industry, and also having use in efficient lighting sources, solar cells, and thin film transistors useful in medical and a range of other sensing, memory and logic applications. This book introduces the theoretical foundations and practical realization of devices in organic electronics. It is a product of both one and two semester courses that have been taught over a period of more than two decades. The target audiences are students at all levels of graduate studies, highly motivated senior undergraduates, and practicing engineers and scientists. The book is divided into two sections. Part I, Foundations, lays down the fundamental principles of the field of organic electronics. It is assumed that the reader has an elementary knowledge of quantum mechanics, and electricity and magnetism. Background knowledge of organic chemistry is not required. Part II, Applications, focuses on organic electronic devices. It begins with a discussion of organic thin film deposition and patterning, followed by chapters on organic light emitters, detectors, and thin film transistors. The last chapter describes several devices and phenomena that are not covered in the previous chapters, since they lie outside of the current mainstream of the field, but are nevertheless important.

Abstract:
The early years of the British Industrial Revolution were dominated by mechanical innovations in cotton spinning. They emerged at a time when raw cotton prices were unprecedentedly high and the supply of all-cotton fabrics from India, the world’s principal producer of cotton textiles, had contracted dramatically. Most «cotton» textiles manufactured in Britain in the mid-18th century were combinations of expensive cotton yarn and cheap linen yarn. Faced with rising material costs, manufacturers economised by increasing the proportion of cheaper linen yarn. The most fashionable cotton products were, however, made entirely from cotton, or required a fixed proportion of cotton yarn. As the cost of cotton rose, their rapidly rising sales provided the principal inducement to improve quality and cut costs by inventing machines for spinning cotton yarn.

Abstract:
Abstract[Context] In manufacturing industries, the design of a product needs to comply with many design rules. These rules are essentials as they help industrial designers to create high quality design in an efficient way. [Problem] However, the management of an ever-increasing number of design rules becomes a real problem, especially for new designers. Even if there exists some knowledge management tools for design rules, their capabilities are still limited and many companies continue to store their design rules in unstructured documents. Nowadays, design rule application is still a difficult task that needs a circular validation process between many expert services in a manufacturing company. [Proposition] In this paper, we will analyze the main existing approaches for design rules application from which we will demonstrate the need of a new approach to improve the current state-of-the-art practices. To minimize rule application impact on the design process, we propose to develop a Context-Aware Design Assistant that will perform design rule recommendation on the fly while designing using computer-aided technologies. Our Design Assistant relies on the modelling of the design rules and the design context in a single knowledge graph that can fuel a recommendation engine. [Future Work] In future work, we will describe the technical structure of the Context-Aware Design Assistant and develop it. The potential outcome of this research are: a better workflow integration of design rules application, a proactive verification of design solutions, a continuous learning of design rules, the detection and automation of design routines.

Abstract:
AbstractIn the frame of a statistical tolerance analysis of complex assemblies, for example an aircraft wing, the capability to predict accurately and fast specified, very small quantiles of the distribution of the assembly key characteristic becomes crucial. The problem is significantly magnified, when the tolerance synthesis problem is considered in which several tolerance analyses are performed and thus, a reliability analysis problem is nested inside an optimisation one in a fully probabilistic approach. The need to reduce the computational time and accurately estimate the specified probabilities is critical. Therefore, herein, a systematic study on several state of the art simulation methods is performed whilst they are critically evaluated with respect to their efficiency to deal with tolerance analysis problems. It is demonstrated that tolerance analysis problems are characterised by high dimensionality, high non-linearity of the state functions, disconnected failure domains, implicit state functions and small probability estimations. Therefore, the successful implementation of reliability methods becomes a formidable task. Herein, advanced simulation methods are combined with in-house developed assembly models based on the Homogeneous Transformation Matrix method as well as off-the-self Computer Aided Tolerance tools. The main outcome of the work is that by using an appropriate reliability method, computational time can be reduced whilst the probability of defected products can be accurately predicted. Furthermore, the connection of advanced mathematical toolboxes with off-the-self 3D tolerance tools into a process integration framework introduces benefits to successfully deal with the tolerance allocation problem in the future using dedicated and powerful computational tools.

Abstract:
AbstractIn this study, we investigate the attentiveness exhibited by participants sourced through Amazon Mechanical Turk (MTurk), thereby discovering a significant level of inattentiveness amongst the platform’s top crowd workers (those classified as ‘Master’, with an ‘Approval Rate’ of 98% or more, and a ‘Number of HITS approved’ value of 1,000 or more). A total of 564 individuals from the United States participated in our experiment. They were asked to read a vignette outlining one of four hypothetical technology products and then complete a related survey. Three forms of attention check (logic, honesty, and time) were used to assess attentiveness. Through this experiment we determined that a total of 126 (22.3%) participants failed at least one of the three forms of attention check, with most (94) failing the honesty check – followed by the logic check (31), and the time check (27). Thus, we established that significant levels of inattentiveness exist even among the most elite MTurk workers. The study concludes by reaffirming the need for multiple forms of carefully crafted attention checks, irrespective of whether participant quality is presumed to be high according to MTurk criteria such as ‘Master’, ‘Approval Rate’, and ‘Number of HITS approved’. Furthermore, we propose that researchers adjust their proposals to account for the effort and costs required to address participant inattentiveness.

Full text
Abstract:
Industrialized house-building (IHB) is a sector offering unique products by adopting an engineer-to-order (ETO) strategy. Customer satisfaction is achieved by adaptation of product solutions and the fast-paced introduction of new technology in combination with short lead-times and cost-efficient production. Product platforms is acknowledged as a strategic enabler for mass customization and increased competitiveness. The strategy has been a necessity in the mechanical industry for several decades. However, for IHB, platforms have only gained interest in recent years. In general, ETO companies struggle with adopting the common product platform approach, set by pre-defined modules and components. Predefinitions require standardization of the product offer which reduces the customization ability which is regarded as a competitive edge. The Design Platform (DP) approach was developed aimed to support ETO companies by utilizing different types of engineering assets in a coherent transdisciplinary model enabling efficient customization. The long-term aim of this work is to investigate and support the DP applicability in IHB to increase efficiency in development and delivery. For this article, data were gathered from a single case study, including workshops with company representatives combined with interviews and document analysis. Based on the data analysis, engineering assets were identified and characterized. Further, a conceptual PLM solution is proposed and outlined to support the DP application combined with the assets. The results suggest that a PLM system can host parts of the DP and that it is applicable in IHB.

Abstract:
Cross-laminated timber (CLT) is a popular engineering wood product in recent years. It has some characteristics of configuration and mechanical properties, which makes it an excellent building material for floor, roof and other places. In Europe and North America, lots of middle and high-rise buildings have adopted CLT as their main structural component. CLT has recently been used to construct public buildings in China. As a building material, the lower rolling shear properties of CLT has always been a concern. To overcome this shortcoming of CLT, the structural composite lumber and bamboo have been employed to develop hybrid CLT. This chapter also presents the latest development and advances of CLT in China.

Abstract:
Quartz glass is a special glass material known as “King of Glass”. The silicon purity of the quartz glass is very high, therefore it is excellent in heat resistance, chemical resistance and optical transparency as compared to other glasses, such as borosilicate glass. At present, it is used in the production field of leading-edge. Now researches are carried out to develop it as key components of special manufacturing equipment, scientific instruments and analysis equipment that require high-precision, high purity, the high light transmittance. However, due to its high heat resistance, it is difficult to be processed into various shapes. As a result, manufactured quarts glass products, generally, might be different even in one batch. To respond to such products for precision instruments, it is preferable to select the heat molding process by flame called “fire-process” in many cases. “fire-process” is the process of forming a softening point of heated quartz glass material by a mixed combustion flame of hydrogen and oxygen. Therefore, a technique for forming a glass material softened by heating is required, and now it is done by human hand processing of engineers. While skilled human technique of long time experience is required in order to produce high precision and an efficient products. Therefore digitizing and analysis of the work of expert engineers with high level of hand skill is needed to increase the processing technology of the engineers less skilled and take advantage in the manufacture of high-precision products. In this study, the differences in the working process between engineers with different years of experience during the “fire-process” of quartz glass material were analyzed. Fire-process is of heating joint glass cylinders during rotating using a dedicated glass lathe machine. The working behaviors of three operators were recorded by videos during “fire-process”. And the thickness of jointed part of final products was measured by ultrasonic equipment to evaluate the quality of the jointed situation. It is found that these differences in the process of heating joint of glass cylinder have effects on the accuracy of finial production and the manufacturing efficiency.

Abstract:
In recent years, high-pressure die-casting magnesium components have been gaining currency worldwide because of the excellent properties that magnesium alloys can offer to meet new product requirements. With the increasing application of magnesium parts worldwide, many research and development projects have been carried out to advance HPDC technology. However, truly optimized mold design and production of defect free castings remains a challenge for die casters. For many HPDC magnesium products, especially those specified for porosity-free and high cosmetic requirement, the challenge not only comes form a lack of a deeper understanding of how molten magnesium alloys fill the mold cavity and form defects, but also from improper preliminary part design. This study proposes a virtual prototyping system that integrates several effective soft and hardware tools for both the part and mold-design engineer to evaluate part manufacturability. Also, investigated in this study are the major causes of those defects that are the predominant cause of rejection of thin walled, leak-free magnesium parts requiring highly cosmetic finishes.

Abstract:
The implementation of a virtual engineering system at John Zink Company, LLC is starting to change the engineering and development processes for industrial combustion equipment. This system is based on the virtual engineering software called VE-Suite being developed at the Virtual Reality Applications Center (VRAC) of Iowa State University. The goal of the John Zink virtual engineering system is to provide a virtual platform where product design, system engineering, computer simulation, and pilot plant test converge in a virtual space to allow engineers to make sound engineering decisions. Using the virtual engineering system, design engineers are able to inspect the layout of individual components and the system integration through an immersive stereo 3D visualization interface. This visualization tool allows the engineer not only to review the integration of subsystems, but also to review the entire plant layout and to identify areas where the design can be improved. One added benefit is to significantly speed up the design review process and improve the turn around time and efficiency of the review process. Computational Fluid Dynamics (CFD) is used extensively at John Zink to evaluate, improve, and optimize various combustion equipment designs and new product development. Historically, design and product development engineers relied on CFD experts to interpret simulation results. With the implementation of the virtual engineering system, engineers at John Zink are able to assess the performance of their designs using the CFD simulation results from a first person perspective. The virtual engineering environment provided in VE-Suite greatly enhances the value of CFD simulation and allows engineers to gain much needed process insights in order to make sound engineering decisions in the product design, engineering, and development processes. Engineers at John Zink are now focusing on taking the virtual engineering system to the next level: to allow for real-time changes in product design coupled with high-speed computer simulation along with test data to optimize product designs and engineering. It is envisioned that, when fully implemented, the virtual engineering system will be integrated into the overall engineering process at John Zink to deliver products of the highest quality to its customers and significantly shorten the development cycle time for a new generation of highly efficient and environmentally friendly combustion products.

Abstract:
An ever more rapidly accelerating trend toward pursuing more efficient gas turbines pushes the engines to hotter and more arduous operating conditions. This trend drives the need for new materials, coatings and associated modeling and testing techniques required to evaluate new component design in high temperature environments and complex stress conditions. This paper will present the recent advances in spin testing techniques that are capable of creating complex stress and thermal conditions, which more closely represent “engine like” conditions. The data from the tests will also become essential references that support the effort in Integrated Computational Materials Engineering (ICME) and in the advances in rotor design and lifing analysis models. Future innovation in aerospace products is critically depended on simultaneous engineering of material properties, product design, and manufacturing processes. ICME is an emerging discipline with an approach to design products, the materials that comprise them, and their associated materials processing methods by linking materials models at multiple scales (Structural, Macro, Meso, Micro, Nano, etc). The focus of the ICME is on the materials; understanding how processes produce material structures, how those structures give rise to material properties, and how to select and/or engineer materials for a given application [34]. The use of advanced high temperature spin testing technologies, including thermal gradient and thermo-mechanical cycling capabilities, combined with the innovative use of modern sensors and instrumentation methods, enables the examination of gas turbine discs and blades under the thermal and the mechanical loads that are more relevant to the conditions of the problematic damages occurring in modern gas turbine engines.

Abstract:
Abstract Instructions on how to assemble a product, known as assembly plans, are traditionally presented to operators in the form of a paper document. The quality, clarity and format of this documentation rely largely on planning engineers’ experience and expertise. Inconsistencies can occur from planner to planner or across project departments which effect product quality. This paper presents a novel structured approach to assembly planning for initial application in the small batch, high technology, precision products sector (eg avionics, mechatronics, electronics). The structured approach capturing best practice is designed to assist experienced planners as well as providing a mechanism for training new planners. The common and variable requirements of assembly planning and information delivery systems in the application sector have been researched and defined.

Abstract:
This paper focuses on enhancing the integration of manufacturing principles and concepts within curricula in mechanical engineering and mechanical engineering technology education programs. The field of manufacturing engineering covers the broad spectrum of topics derived from the definition, “Manufacturing requires that a modification of the shape, form, or properties of a material that takes place in a way that adds value”. (ABET, Inc. 2010) The ASME’s Vision 2030 surveys of industry engineering supervisors and early career mechanical engineers have illustrated that the curricula of mechanical engineering and related programs have an urgent need to enhance students’ comprehension of ‘how things are made and work,’ e.g., the knowledge and skills needed to design and efficiently produce products via high-performance systems. (Danielson, et. al. 2011) This session is designed to be primarily a dialog among the participants and the presenters, focusing on a model for the manufacturing field called The Four Pillars of Manufacturing Knowledge, developed by the Society of Manufacturing Engineers (SME 2011a), and how it relates to mechanical engineering education. Broader issues and resources related to enhancing manufacturing education are also presented.

Abstract:
Abstract Spray Systems are used very extensively in a wide range of industrial applications. Injection of liquid fuel in gasoline and diesel automotive engines, gas turbine aircraft and land-based engines, rocket engines and a wide variety of industrial furnaces and boilers, require improved control of atomization and spray characteristics to improve performance and efficiency and to reduce emission of pollutants to satisfy EPA regulations. Spray painting of automobiles, aircraft, bridges and a large range of manufactured products results in the waste of large proportions of paint that does not hit the target and is carried away by offspray, which requires expensive treatment to prevent pollution. In manufacturing processes, molten metal sprays are used for direct manufacture, using near net shaping, high temperature arc spray coatings (thermal spraying) and for coatings. The need to achieve uniform thickness film layers with low porosity, requires control of drop size, velocity, temperature and number density in the spray. More than 80% of agricultural crops are sprayed with herbicides, fungicides and insecticides, using aircraft and tractors. Drop size needs to be maintained sufficiently large during evaporation to prevent drift by wind away from the target crop. Drops that are too large cause wastage and low target transfer efficiencies. Control is required of initial drop size distributions and subsequent changes of spray characteristics from nozzle to target crops. Many industrial chemical and food processes use spray drying where liquid slurries, colloids and solutions are injected into heated gas (air) environments. Control of atomization and spray characteristics is required in order to meet the end product specifications, of particle size, agglomeration, porosity and friability. In the field of medicine, inhalation therapy is used for treatment of respiratory diseases. New developments include inhalation of cyclosporin to prevent rejection after lung transplants, deep lung inhalation of insulin as a more effective and comfortable treatment for diabetics and inhalation of chemotherapy for prevention of lung cancer for heavy smokers. The generation of monosize particles in nebulizers targeted to particular locations in the respiratory tract and lung surfaces requires accurate control of particle size and velocity during inhalation. Control of all these spray processes is achieved by improved atomizer design and accurate measurement of spray characteristics by phase Doppler, diffraction and imaging laser diagnostic instruments.

Full text
Abstract:
Automotive design relies heavily upon the use of targets. In addition to providing direction and context for the development of new products, the target-setting process forms links between the subjective and objective characteristics of a product and, when executed properly, can help ensure compliance with regulations and feasibility guidelines. At the start of the target-setting process, business and marketing activities define a desired competitive position for a proposed product using data gathered in the various methods of market analysis. From this desired position, business and marketing develop high-level targets for attributes like performance, comfort, and cargo capacity based upon the current and predicated future qualities of products that are perceived to be potential competitors in the marketplace. These business targets guide the formulation of engineering targets. Engineers interpret the business targets to determine what combination of engineering attributes would best accomplish them. These attributes form the basis of a starting set of engineering targets that must be evaluated against databases of corporate, industry, and governmental regulations as well as rules that indicate the design viability and manufacturability of the product. This paper discusses the source, development, and use of targets in automotive engineering as well as formalisms and methods to describe and handle the target-setting and verification processes. In addition, this paper discusses proposed information technology-based and knowledge-based techniques to strengthen and streamline this critical aspect of the engineering design process.

Abstract:
Abstract In socialistic countries, customer satisfaction and the market conditions were not of high priority: Some selected parts of the market products were of satisfactory costs and quality to customers. Quality and costs of a product decide on its success in the world-wide market. The wishes and expectations of the customer for a high-quality and low-priced product continue to grow, however, with the desire for faster availability of this product. The customer determines also the delivery time and other competitive factors as the durability of the product. At present the trend goes towards shorter product life cycles, which in turn requires reduced time spent on the product development. With these complex market requirements and growing diversity of the products the engineer faces new challenges in his development tasks. It can be paraphrased as follows: In reduced lifecycles a quality-assured and advantageous product has to be developed despite increasing complexity of the design and demands for reduction of material used, manpower and monetary spending. For the solution of this complex problem the following suggestions are tested and implemented: • Structured design process for the development process, • Simultaneous work where ever possible during the development stages, • Employment of modern resources for the product development, • Use of information technology and • Implementation of rapid prototyping for models and in secondary manufacturing processes. An important research field at the Department of Mechanical Engineering Design at the Otto-von-Guericke-University Magdeburg is research and further development of productive procedures and tools for the realization of a computer integrated product development process. This process includes the effective application of technologies to produce the prototypes for presentation, producibility analysis and production. Of particular interest is the closed process chain (loop) from Solid Modeling via Rapid Prototyping and 3D-Digitizing where the entry point of this process chain depends on the needs of the application or particular interest of the innovating company. Information for faster and more competitive preparation, verification and Re-Engineering of existing and established products, which have to be adjusted to the world-market needs, will be made available. The results of this applied research offer opportunities to display new developed products for the lagging industries in the former East Germany, and furthermore arranging for necessary venture capital to produce the product, to gain information about possible suppliers and manufacturing opportunities in order to minimize the investors’ risks of an enterprise.
