Abstract The paper is aimed at measuring innovation and qualification of technological operations in automotive production within the quality management system. Quality requirements according to ISO/TS 16949 promote a process approach for the design and development, production, installation and servicing of automotive products, which can result in increased quality, reduced variation and increase of efficiency. The solution focuses on the process of approval of parts in series production (Production Part Approval Process – PPAP). The PPAP purpose is to determine whether an organization properly understood all customer requirements listed in the specifications and records of the technical design of the product. PPAP further verifies that the process has the potential to produce a product in series production so that customer requirements will be met, in actual production volume and at the agreed rate of production. Specifically, a toothed winch of hydroelectric generator is solved by the case study.

Full textAbstract:
Assembly sequence planning plays an essential role in the manufacturing industry. However, there still exist some challenges for the research of assembly planning, one of which is the weakness in effective description of assembly knowledge and information. In order to reduce the computational task, this paper presents a novel approach based on engineering assembly knowledge to the assembly sequence planning problem and provides an appropriate way to express both geometric information and nongeometric knowledge. In order to increase the sequence planning efficiency, the assembly connection graph is built according to the knowledge in engineering, design, and manufacturing fields. Product semantic information model could offer much useful information for the designer to finish the assembly (process) design and make the right decision in that process. Therefore, complex and low-efficient computation in the assembly design process could be avoided. Finally, a product assembly planning example is presented to illustrate the effectiveness of the proposed approach. Initial experience with the approach indicates the potential to reduce lead times and thereby can help in completing new product launch projects on time.

PeerJ Computer Science 5 (July 1, 2019): e203. http://dx.doi.org/10.7717/peerj-cs.203.
Full textAbstract:
University employment and, specifically, employability has gained relevance since research in these fields can lead to improvement in the quality of life of individual citizens. However, empirical research is still insufficient to make significant decisions, and relying on powerful tools to explore data and reach insights on these fields is paramount. Information dashboards play a key role in analyzing and visually exploring data about a specific topic or domain, but end users can present several necessities that differ from each other, regarding the displayed information itself, design features and even functionalities. By applying a domain engineering approach (within the software product line paradigm), it is possible to produce customized dashboards to fit into particular requirements, by the identification of commonalities and singularities of every product that could be part of the product line. Software product lines increase productivity, maintainability and traceability regarding the evolution of the requirements, among other benefits. To validate this approach, a case study of its application in the context of the Spanish Observatory for University Employability and Employment system has been developed, where users (Spanish universities and administrators) can control their own dashboards to reach insights about the employability of their graduates. These dashboards have been automatically generated through a domain specific language, which provides the syntax to specify the requirements of each user. The domain language fuels a template-based code generator, allowing the generation of the dashboards’ source code. Applying domain engineering to the dashboards’ domain improves the development and maintainability of these complex software products given the variety of requirements that users might have regarding their graphical interfaces.

This paper presents the design, implementation and performance evaluation of the linear processor array accelerator for matrix multiplication. We call it matrix multiplication processor (MMP). The MMP is composed of n processing elements (PEs) connected in a chain, distributed memory, and dedicated address generator unit (AGU) to generate memory addresses. By using this approach, address generation does not increase the processing time. The AGU is one major difference in the proposed architecture compared to graphics processing units (GPUs) that use ALUs to create addresses. MMP is based on FPGA technology since this circuits possess extreme degree of parallelism and ability to customize the RAM and data path architecture to the computation. We have considered performance metrics of the proposed architecture in the sense of number of PEs, execution time, speedup, efficiency and gain factor. We have implemented AGU and PE in Xilinx Spartan 2E FPGAs using ISE 9.01 as a software tool. We compare our design with respect to the execution time, number of PEs, AT measure, speedup and efficiency with other solutions proposed in the literature.

Full textAbstract:
<span>A multiplier circuit is one of the most important functional blocks of many nano-electronic, control and automation applications. In this work, an energy-efficient multiplier is reported based on a 3:2 compressor. The multiplier has been designed in three different parts. In the first part, a partial product (PP) generator is used. In the second part, the partial products are reduced which is termed as PPP (partial product processing). Whereas in the third step final addition is performed. PPs are produced by using AND gates. The PPP is designed in two-phase. In the first phase, the Wallace tree logarithm has been used to reduce the PPs. Whereas, in the second phase the PPs are reduced by using energy-efficient half adder and 3:2 compressor. At last, in the third step, by using a carry-save adder final addition has been computed. The performance analysis of the designed multiplier is evaluated and compared with other multiplier circuits. The multiplier shows performance improvements by 20.55%-46% for the power supply variation from 1.2 V to 0.6 V. All the simulations and analyses have been carried out by using the Synopsys EDA tool.</span>

This debate explored the state-of-the-art in human factors education and the skills that are desired as professionals enter industry to design consumer products. This debate addressed the specific needs of consumer product design, where a consumer product was defined as a product that is purchased by the end user and used by this person. Inherent in this definition is the fact that both the purchase and use of this product are left to the discretion of the user. Therefore, this product must not only facilitate the efficient completion of a task but also satisfy a basic user need. This debate attempted to arrive at a consensus on potential improvements to the training of individuals within the university environment, and to identify potential industry contributions to improve the quality of education of human factors and ergonomics professionals in consumer product design. This consensus was obtained by bringing together industry representatives from Fortune 500 companies and design firms with professors from prominent universities. University representatives provided a short overview of their human factors curriculum, the skills that this curriculum provides their students and views on how additional industry involvement could improve the quality of education. Industry representatives provided an overview of their organizations and the skills that are expected of new employees as they enter the work force. The debate occurred as differences were identified between the views expressed during these presentations. Among the topics debated were: 1) the importance of student internships versus additional course work, 2) the importance of general human factors principles versus extensive course work within specialized areas, 3) the need for education of theoretical knowledge versus applied training where students learn to make tradeoffs when the ideal cannot be achieved, 4) training involving communication within multidisciplinary teams versus relatively homogeneous human factors programs, 5) a focus on methods for determining consumer needs versus historical methods for determining needs of trained operators of large systems, and 6) training the human factors graduate as an evaluator of consumer products versus a creator/generator of new product concepts.

Full textAbstract:
A self-oscillating high-voltage generator is proposed to supply voltage for a suspension system in order to control the damping force of an electrorheological (ER) fluid shock absorber. By controlling the output voltage level of the generator, the damping force in the ER fluid shock absorber can be adjusted immediately. The shock absorber is part of the suspension system. The high-voltage generator drives a power transistor based on self-excited oscillation, which converts dc to ac. A high-frequency transformer with high turns ratio is used to increase the voltage. In addition, the system uses the car battery as dc power supply. By regulating the duty cycle of the main switch in the buck converter, the output voltage of the buck converter can be linearly adjusted so as to obtain a specific high voltage for ER. The driving system is self-excited; that is, no additional external driving circuit is required. Thus, it reduces cost and simplifies system structure. A prototype version of the actual product is studied to measure and evaluate the key waveforms. The feasibility of the proposed system is verified based on experimental results.

Interactive Digital TV (iDTV) enhances viewers’ experience and participation by engaging them with an active role. The development of interactive software requires the employment of usability criteria to provide satisfactory experiences for users. In addition, the diverse characteristics of television programs require efficient processes for interactive software development. In Latin America, the process of implementing DTV is in progress, so the current stage of development of interactive applications is too incipient and immature to support industrial, quality-level development. This paper proposes combining software reuse strategies, specifically, software product lines (SPLs) and user-centered interaction design patterns, to improve productivity and quality. A generic feature model for the automatic generation of iDTV applications and an SPL-iDTV tool that supports the model are presented. The proposal is evaluated with two studies: an experiment that attempts to reproduce real application prototypes that were originally developed manually, through the use of patterns, and an evaluation of the quality of the SPL.

Employee selection is an activity to get human resources for a company. Researchers conducted research at PT. Gajah Tunggal Tbk where currently the selection process still uses the conventional method, the current assessment of participants uses technical and non-technical tests with interview methods but at present the company does not yet have a standardized weighting of values tested, so companies sometimes have difficulty determining who should receive from the test participants. Based on the above conditions, researchers conducted decision support system design research using the Weighted Product method to assist companies in getting the right employees according to the employees' technical needs and abilities. Decision support system development refers to the results of data collection using qualitative and quantitative data collection methods. Development of decision support system is built based on the waterfall system development model using the PHP programming language. The system testing method uses the black box method.

The turbo-pump and turbine are driven by liquid fuel fed into a gas generator, where the fuel is oxidized with a liquid oxidizing agent. For stable operation of the turbine, the combustion temperature of the gas generator must be maintained below 1000 K. The thermodynamic characteristics of kerosene oxidation in the gas generator must be understood to optimize the design and operation conditions of the liquid-fueled rocket engine system. Herein, the 3-species surrogate mixture model for kerosene was selected, and the detailed Dagaut’s kerosene oxidation mechanism consisting of 225 chemical species and 1800 reversible chemical reactions was utilized. The exit gas temperature and product gas composition in the gas generator under fuel-rich conditions were simulated by applying the perfectly stirred reactor model. The perfectly stirred reactor model was used in combination with the liquid spray model for evaporation of the droplets and the two-temperature model for evaluation of the flame temperature separately from the locally averaged reactor temperature. The theoretical prediction of the gas species fraction and soot yield could be improved by applying the tar cracking mechanism, where the reaction characteristics under high temperature were taken into account.

Among the current 3G SVCs, the one with the highest compensating capacity is the static var generator, which is featured by smooth and continuous bipolar reactive power, quick responding and small loss, and widely applied in petrochemical, metallurgy, wind power and power transmission and distribution, etc, working out power quality problems. As demand for static var compensators in market grows, LV SVG comes to the stage. Compared with HV and MV SVGs, although LV SVG is simple in structure, it has stricter requirements on compensating capacity and stability, which requires R&D to consider more technical details in product design.

Full textAbstract:
It is possible to increase the sensitivity of electromagnetic-acoustic transducers by three main methods: increasing the induction of a polarizing magnetic field; increase in strength of high-frequency current in the inductor of the converter; using modern methods of processing information packet pulses excited and received from the product. The increase in magnetic field induction of the converter is limited by the capabilities of modern powerful permanent magnets. In addition, there are significant difficulties in monitoring ferromagnetic control samples, due to the large pressing force between the sample and the transducer and sticking of scale to the transducer. Usage of modern processing methods significantly complicates and increases the cost of electromagnetic-acoustic testing devices. Of the selected sensitivityincreasingmethods, the most acceptable way is to increase the power of high-frequency current generators under the condition of excitation of packet pulses. Power supply process of the converter is carried out in two stages. Meander type powerful high-frequency current pulses are excited, which ensures operation of the output transistors in key mode. Isolation of a powerful sinusoidal high-frequency packet current pulse is carried out directly on the electromagnetic - acoustic transducer, the elements of which are included in the resonant circuit with low quality factor. Based on the transistors switched in the push-pull circuit in the key mode, a small-sized generator design has been created that excites a peak current of up to 800 A in the electromagnetic-acoustic transducer and a voltage of up to 3 kV in the transducer in the frequency range 0.3 ... 8 MHz. It was experimentally determined that the new design of the probe pulse generator made it possible to increase the amplitude of pulses reflected from a flat-bottom reflector with a diameter of 2 mm with respect to the interference amplitude by more than 2 times.

Full textAbstract:
Design is a challenging task that is crucial to all product development. Advances in design computing may allow machines to move from a supporting role to generators of design content. Generative Design systems produce designs by algorithms and offer the potential for the exploration of vast design spaces, the fostering of creativity, the combination of objective and subjective requirements, and the revolutionary integration of conceptual and detailed design phases. The application of generative methods to the design of discrete, physical, engineered products has not yet been reviewed. This paper reviews the Generative Product Design systems developed since 1998 in order to identify significant approaches and trends. Systems are analyzed according to their primary goal, generative method, the design phase they focus on, whether the generation is automatic or interactive, the number of design options they generate, and the types of design requirements involved in the generation process. Progress using this approach is recognized, and a number of challenges that must be addressed in order to achieve widespread acceptance are identified. Possible solutions are offered, including innovative approaches in Human–Computer Interaction.

This paper describes the transformation of an existing set of heterogeneous product knowledge into a coherent design repository that supports product design knowledge archival and web-based search, display, and design model and tool generation. Guided by design theory, existing product information was analyzed and compared against desired outputs to ascertain what information management structure was needed to produce design resources pertinent to the design process. Several test products were catalogued to determine what information was essential without being redundant in representation. This set allowed for the creation of a novel single point of entry application for product information and the development of a relational database for design knowledge archival. Web services were then implemented to support design knowledge retrieval through search, browse, and real-time design tool generation. Further explored in this paper are the fundamental enabling technologies of the design repository system. Additionally, repository-generated design tools are scrutinized alongside human-generated design tools for validation. Through this process researchers have been able to improve the way in which artifact data are gathered, archived, distributed and used.

Purpose The purposes of this paper are to propose a different profitability metric (i.e. anchor category profits) at the category level based on the concept of anchor categories and to illustrate how such a metric can be calculated in field settings to offer a balanced view of profit structure from both the accounting and marketing perspectives. Design/methodology/approach First, the concept of anchor categories is developed drawing on anchor effects theory and automatic cognitive processing theory. Based on anchor categories, this paper proposes a formula for calculating anchor category profits. Using the data collected with a survey instrument, this paper calculates accounting profits and anchor category profits for two grocery stores. Findings The intra-store analysis of accounting profits and anchor category profits reveals that the two profit measures project different profit contribution patterns by product categories for each store. The inter-store analysis provides quite different, yet useful information about profit structures for the two grocery stores. Although the two stores are similar in terms of accounting profits, their anchor category profits show different pictures regarding profit contribution patters by product categories between the two stores, revealing that different categories attract customers to different stores. Practical/implications Comparing accounting profits and anchor category profits allows retail managers to identify traffic generator categories and cash generator categories, which helps retail managers develop more effective category management to increase storewide profits. Originality value This paper increases understanding of the relationship between product categories and store choice behavior by offering a theoretical rationale to explain why some product categories influence consumers’ store choice. This paper also proposes anchor category profits as a more implementation-friendly category-level profitability metric that combines accounting principles with consumers’ shopping trip planning behavior.

We consider the valuation of derivative contracts on baskets of risky assets whose prices are Lévy-like Feller processes of tempered stable type. The dependence among the marginals' jump structure is parametrized by a Lévy copula. For marginals of regular, exponential Lévy type in the sense of Ref. 7 we show that the infinitesimal generator [Formula: see text] of the resulting Lévy copula process is a pseudo-differential operator whose principal symbol is a distribution of anisotropic homogeneity. We analyze the jump measure of the corresponding Lévy copula processes. We prove that the domains of their infinitesimal generators [Formula: see text] are certain anisotropic Sobolev spaces. In these spaces and for a large class of Lévy copula processes, we prove a Gårding inequality for [Formula: see text]. We design a wavelet-based dimension-independent tensor product discretization for the efficient numerical solution of the parabolic Kolmogorov equation [Formula: see text] arising in valuation of derivative contracts under possibly stopped Lévy copula processes. In the wavelet basis, diagonal preconditioning yields a bounded condition number of the resulting matrices.

Full textAbstract:
Spray drying is currently used to obtain powder products from suspensions. It is considered the most effective type of drying for such media. The complexity of the drying process is associated with thermal destruction of components, which degrades the properties of the product and imposes significant restrictions on temperature condition. The present research features the simulation of transient modes of operation of the solenoids to generate a controlled cavitation effect when applied to a stream of acoustic vibrations using a magnetostrictive generator of ultrasound. The authors propose a new design of spray nozzle for drying suspensions with counter-connected solenoids. Such solenoids can cause deformation of the main suspension supply line. The intensity of the cavitation processes depends on the dynamics of the solenoid actuation. The paper introduces a mathematical modeling of transient modes of operation for ultrasonic frequency generator solenoids that create a controlled cavitation effect when applied to the jet of acoustic oscillations of this frequency. When modeling the process of operation of solenoids, the main criterion for changing the intensity of cavitation is the average rate of change in the volume of the cavity at the stage of its collapse, related to one cycle of oscillations for a spherical cavity. An increase in the static pressure of the liquid led to a shift in the phase of the collapse of the cavity. As a result of the chosen mathematical model, a numerical experiment with modeling in the MathCAD program was carried out. It revealed some graphical dependences of the change in U(t), L(t), and R(t). The obtained data allow one to predict the ballast induction and active load (R, L) for the control of transients in the solenoid of the ultrasonic generator. These dependences make it possible to choose more effective parameters for drying suspensions, which is especially important for heat- sensitive components.

Full textAbstract:
Purpose Recent developments suggest that pharmaceutical companies are acquiring existing products through mergers to improve their business models; however, this paper aims to emphasize R&D as a strategy to boost revenues and counteract the risks of existing products that may be unreliable. In light of Pfizer’s upcoming US$160 billion merger deal with Allergan, the paper’s objective is to illuminate the outcomes of Pfizer’s previous megamergers (>US$10 billion) to indicate what could happen to the company’s economic profits if it only focused on the acquisition of established drugs instead of diversifying and creating new products. Design/methodology/approach The paper uses a combination of industry studies to make an assessment of the economic implications of conducting a megamerger (highlighting the need for further R&D). The assessment included a review of Pfizer’s M&A outcomes in two of its previous megamergers and an evaluation of a McKinsey study conducted on the economic impact of 17 pharmaceutical megamergers. Findings The paper provides insights on the negative profit outcomes in Pfizer’s past megamergers. Furthermore, the positive profit outcomes of pharmaceutical megamergers demonstrate that other M&A motives, such as R&D rationalization and product diversification, may be responsible for bringing up the group’s performance. Investing in R&D would be a good strategy for Pfizer to counteract the risk of relying on existing products as revenue generators. Practical implications The paper provides strategic insights and practical thinking that have influenced some of the world’s leading organizations. Originality/value The paper suggests that Pfizer should place more emphasis on R&D as a revenue generator in face of its upcoming US$160 billion megamerger with Allergan, despite the current industry trends favouring the acquisition of existing products.

Full textAbstract:
In this paper, an innovative closed hydraulic wind turbine with an energy storage system is proposed. The hydraulic wind turbine consists of the wind rotor, the variable pump, the hydraulic bladder accumulator, the variable motor, and the synchronous generator. The wind energy captured by the wind rotor is converted into hydraulic energy by the variable pump, and then the hydraulic energy is transformed into electrical energy by the variable motor and generator. In order to overcome the fluctuation and intermittence shortcomings of wind power, the hydraulic bladder accumulator is used as an energy storage system in this system to store and release hydraulic energy. A double-loop speed control scheme is presented to allow the wind rotor to operate at optimal aerodynamic performance for different wind speeds and hold the motor speed at the synchronous speed to product constant frequency electrical power regardless of the changes of wind speed and load power. The parameter design and modeling of 600 kW hydraulic wind turbine are accomplished according to the Micon 600 kW wind turbine. Ultimately, time-domain simulations are completed to analyze the dynamic response of the hydraulic wind turbine under the step change conditions of wind speed, rotor speed input, and load power. The simulation results validate the efficiency of the hydraulic wind turbine and speed control scheme presented, moreover, they also show that the systems can achieve the automatic matching among turbine energy, accumulator energy, and generator output energy.

AbstractThe dual-polarization upgrade to the WSR-88D network of weather radars included the addition of a hydrometeor classification algorithm (HCA) to the Open Radar Product Generator (ORPG). The HCA product categorizes each Level-III radar range–azimuth cell into one of 10 classifications or marks it as “unknown.” However, not all target types fall under the 10 classification options. For this reason, multiple studies have examined adding new classes to the operational HCA. In this study, a new “inanimate” class is developed for additional hydrometeor classification in the ORPG and is described in detail. This class encompasses nonweather phenomena such as chaff (the primary motivation of this work), sea clutter, and some types of combustion debris and radio frequency interference. The design process is detailed, including human truthing, data selection, and optimization with a genetic algorithm. Multiple case examples are presented and analyzed, both qualitatively and quantitatively. Quantification is put into perspective with previous studies for a better understanding of the algorithm’s performance and impact. A discussion of applications, including subclassing, chaff detection, and implementation as an “aviation” classification algorithm in the ORPG, is presented.

The modern pulverized-coal power plant is the product of continuous design experience and component improvement in the 20th century. In recent years, studies of the effect of high temperatures on turbine materials have led to major worldwide research and development programs on improving the thermal cycle by raising turbine-inlet pressure and temperature. This paper reviews the importance of various parameters in trying to optimize a turbine cycle designed for advanced steam conditions. Combinations of throttle pressure (between 3500 psi [24.1 MPa] and 10,000 psi [70MPa]), throttle and reheat temperature(1000°F [538°C] to 1400°F [760°C]), and number of reheats are explored to establish a realistic turbine cycle design. Assessments and trade-offs are discussed, as applicable. Critical cycle components, feedwater cycle arrangements, and reheat pressure selections are analyzed in establishing an optimized steam turbine-boiler cycle for a 1000 MW turbine-generator. Applicability of results to smaller advanced steam turbines is given. A brief update on the high-temperature Wakamatsu turbine project in Japan is also given.

The most common way to increase power and reduce fuel consumption by modern power plants is contact cooling of a gas or air flow by water injection. A promising development of this direction is to use aerothermopressor technologies. The use of heat air, which is compressed by the power plant compressors, accelerates the flow to a speed close to the sound one and almost instantaneous evaporation of injected water (the effect of thermo-gas-dynamic compression). It is important to determine the rational parameters of the organization of thermophysical and hydrodynamic processes when developing such technologies. In this case, one should be taken into account the appropriate development of the flow path design and a special software product. It is necessary to use methods and means to determine the optimal operating parameters of the power plant heat recovery systems. This paper presents a block diagram and an algorithm of a rational methodology for designing an aerothermopressor, which makes it possible to accurately determine the efficiency of using an aerothermopressor as part of a power plant (based on a gas turbine engine) for cooling cycle air, considering the peculiarities of operating modes in the flow path, as well as under various climatic operating conditions. The algorithm of a rational methodology for designing aerothermopressor technologies allows calculating the characteristics of equipment, systems, and circuit design solutions when used as part of a power plant: an electric generator; heat-using refrigerating machines (ejector refrigerating machines, absorption refrigerating machines); turbine generator or steam generator as part of a trigeneration unit or as part of a turbo-compound unit (power plants of marine vessels); recovery boiler of one or two pressures. Modeling the aerothermopressor-cooling system operation makes it possible to reveal the effectiveness of using such a system as part of a power plant and compare it with traditional methods of cooling and humidifying cycle air.

Purpose: Product tax is an essential tool for governments, serving both as a revenue generator and fiscal policy instrument. The paper examines short-run and long-run relationships shared by product taxes and economic growth in Nigeria for the period, 1981 to 2019. Approach/Methodology/Design: The study checks the stationarity properties of the series by testing them for unit roots using Augmented Dickey Fuller (ADF) method and Philip-Perron unit root test. Both unit root tests indicate that the series is stationary at first difference. In view of this, the study deploys a cointegration technique, Engle-Granger two-step procedure to determine the long-run and short-run links shared by the variables of interest. The Error Correction Mechanism (ECM) estimation and the Granger causality estimations for speed of adjustment and causality of the variables were also used. Findings: The results reveal that product tax revenues and economic growth cointegrate in the long-run; while product tax revenues exert a significant positive effect on economic growth both in the short-term and long-term. The outcome of the Error Correction Mechanism (ECM) estimation shows a swift speed of adjustment to a new long-run equilibrium after a shock. The outcome of the Granger causality estimations indicates a uni-directional causality from economic growth to revenues from product taxes. Practical Implications: This study is significant at this point when the country is facing increasing economic challenges. It will be useful to policy makers who might want to explore the possibility of using product tax as a fiscal policy tool, and a source of revenue to augment the declining revenue of the government from other sources. Originality/value: The paper explores short-run and long-run relationships shared between product taxes and economic growth in Nigeria using a two-step procedure of Engle and Granger, and it verifies causality link between the later and the former.

Purpose – The purpose of this paper is to conceptualise and discuss the possible insights that can be generated for product development by analysing the user-generated content available from various social media platforms. Design/methodology/approach – The paper reviews the role of user generated content in developing products and its features (e.g. appearance and shape). It delineates the directions in which the relationship between social media content and customer oriented concepts evolve while developing successful new products. Findings – The review and arguments presented in this paper suggest that the social media approach adds more value than the traditional approaches for obtaining insights about the products. Availability of users’ opinions and information about existing products provide insights for the improvement in the product design process. Co-creation and self-construal are important components that are based on customer engagement and customer behaviour, respectively, in the product design and development. Practical implications – As social media creates new ways of communication with users, businesses can include users into the product development process to improve and refine their products or for making the next generation of products. Originality/value – This paper suggests a new approach in getting useful insights about the products from user-generated contents. This way of using social media helps businesses to move forward from the traditional product development paradigms.

Full textAbstract:
A grammatical approach to product design is demonstrated. In particular, shape grammars are shown to be especially useful for products that are differentiated primarily on the basis of form yet driven by function; they allow products to be designed as a sequence of well-defined steps. However, it is not always clear how to choose the sequence of rules that should be applied to generate the final shape. In this paper we demonstrate that at each stage during the process, partial designs of the final product can be used to provide feedback to the designer based on specific design objectives and thus suggest possible rule choices. We take advantage of the shape grammar for the generation of coffeemakers introduced by Agarwal and Cagan, and associate with the grammar rules expressions that model manufacturing costs. With each application of a shape grammar rule, an understanding of the overall cost of manufacturing the product is incrementally improved. Thus, at each stage of the design process the designer has an indication of what the overall cost of the product will be and how the selection of one grammar rule over another influences the final cost. Once the complete product is generated, an appraisal of its manufacturing cost is given to the designer. This evaluation methodology helps the designer understand the implications of decisions made early on in the design process. We have also verified the accuracy of this approach through the costs of some commercially available coffeemakers, generated by this method, which are comparable to the costs for those designs listed in the literature.

Generation of the part programs, or tool paths, for products to be manufactured by computer numerical control (CNC) machines is very important. Many methods have been used to produce part programs, ranging from manual calculations to computer aided design/ manufacturing (CAD/CAM) systems. This work introduces a new technique for generating the part programs of existing products using the latest technology of computer vision. The proposed vision system is applicable for two-dimensional vertical milling CNC machines and is calibrated to produce both metric and imperial dimensions. Two steps are used to generate the part program. In the first step, the vision system is used to capture an image for the product to be manufactured. In the second step, the image is processed and analysed by software specially written for this purpose. The software CNCVision is fully written (in lab) using Microsoft Visual C++ 6.0. It is ready to run on any Windows environment. The CNCVision software processes the captured images and applies computer vision techniques to extract the product dimensions, then generates a suitable part program. All required information for the part program is calculated automatically, such as G-codes, X and Y coordinates of start-points and end-points, radii of arcs and circles and direction of arcs (clockwise or counterclockwise). The generated part program can be displayed on screen, saved to a file or sent to MS Word or MS Excel. In addition, the engineering drawing of the product can be displayed on screen or sent to AutoCAD as a drawing file.

AbstractLambda calculus is the basis of functional programming and higher order proof assistants. However, little is known about combinatorial properties of lambda terms, in particular, about their asymptotic distribution and random generation. This paper tries to answer questions like: How many terms of a given size are there? What is a ‘typical’ structure of a simply typable term? Despite their ostensible simplicity, these questions still remain unanswered, whereas solutions to such problems are essential for testing compilers and optimizing programs whose expected efficiency depends on the size of terms. Our approach toward the aforementioned problems may be later extended to any language with bound variables, i.e., with scopes and declarations. This paper presents two complementary approaches: one, theoretical, uses complex analysis and generating functions, the other, experimental, is based on a generator of lambda terms. Thanks to de Bruijn indices (de Bruijn, N. (1972) Lambda calculus notation with nameless dummies, a tool for automatic formula manipulation, with application to the Church-Rosser theorem. Indagat. Math.34(5), 381–392), we provide three families of formulas for the number of closed lambda terms of a given size and we give four relations between these numbers which have interesting combinatorial interpretations. As a by-product of the counting formulas, we design an algorithm for generating λ-terms. Performed tests provide us with experimental data, like the average depth of bound variables and the average number of head lambdas. We also create random generators for various sorts of terms. Thereafter, we conduct experiments that answer questions like: What is the ratio of simply typable terms among all terms? (Very small!) How are simply typable lambda terms distributed among all lambda terms? (A typable term almost always starts with an abstraction.)

Full textAbstract:
In allusion to the rapid design for building door and window products, a rapid design method based on generalized modularization was put forward. According to the combination of generalized modules, the product configuration model was automatically generated on the basis of generalized modular planning, and then the rapid design for building door and window products was realized by the instantiation of product configuration model. With the method, product designs and associated knowledge can be reused and the design cycle can be effectively shortened. A designing system for building door and window products was developed and applied in some enterprises, with satisfactory results.
