Abstract:
Product development is a multi-faceted role that a growing number of engineers are tasked with. This represents a significant shift in career paths for those employed in the chemical and materials engineering disciplines, who typically were concerned with bulk commodity manufacturing. This paradigm shift requires the undergraduate curriculum to be adapted to prepare students for these new responsibilities. The authors present here on a product design capstone course developed for chemical engineering seniors at the University at Buffalo (UB), The State University of New York (SUNY). The course encompasses the following themes: a general framework for product design and development (identify customer needs, convert needs to specifications, create ideas/concepts, select concept, formulate/test/manufacture product; and (nano)structure-property relations that guide the search for smart/tunable/functional materials for contemporary needs and challenges. These two main themes are enriched with case studies of successful products. Students put the course material into practice by working through formulated product design projects that are drawn from real-world problems. The authors begin by presenting the course organization, teaching techniques, and assessment strategy. They then discuss examples of student work to show how students apply the course material to solve problems. Finally, they present an analysis of historical student performance in the course. The analysis seeks to identify correlation between related student deliverables, and also between the Product Design course and a prerequisite materials science and engineering course.

Abstract:
Concurrent engineering is a systematic approach for integration and concurrent design of products. The systematic approach intends to consider all elements influencing the products and their related processes during the product life-cycle, such as manufacturing, support, costs, quality, user requirements etc. Especially the engineering design phase should be considered for improvements. This paper presents some of the major and most acknowledged concepts, ideas and principles of concurrent engineering. They are among others:trends and demands to product development time and product life-timeintroduction of a concurrent engineering environment, including the forces, dimensions, mechanisms and targets of concurrent engineeringthe design process, including considerations regarding to the quality and extent of iteration loops and construction of improved design processesquality function deployment, a method for identifying and managing requirements which is based on interfunctionality and interdisciplinary project-teams. The paper also discusses concurrent engineering in proportion to traditional design theories. The human and organization aspects in concurrent engineering are treated superficially. Finally, some applied concepts, principles and methods are briefly presented. This paper gives an overview and introduction to concurrent engineering.

Abstract:
Today mechanical engineering is one of the most dynamically developing industries. The products of this industry are becoming more and more complex, requiring the continuous introduction of new high technologies into the production process. In addition, the change in the preferences of consumers of mechanical engineering products associated with an increase in the degree of automation and robotization of their production processes leads to the need to apply more flexible product design approaches. These approaches should allow the manufacturer to respond quickly to changing customer needs. Thus, machine-building enterprises need to provide not only the best price-quality ratio, but also to offer a unique set of product functions - a concept that satisfies all the needs of target consumers. In other words, the ability to create product value based on the individual needs of customers is a competitive advantage for a company in the struggle for market share. The application of Value Engineering Method is able to solve these problems.

Abstract:
Currently, the sales of decorative lighting products are very low because the design of decorative lights are less attractive to consumers. Therefore, the company must develop the product to produce quality products that are updated and attractive to consumers. This research aims to develop the decorative light products using value engineering. Value engineering was used to increase benefits withoutt increasing costs, reducing costs without reducing benefits, or a combination of both. This research was conducted to find out the level of efficiency that can be achieved from several recommended alternatives. Research results showed that the value of the initial design (Product A) was 3,48 x 10-7; product B was 3,16 x 10-7; and product C was 8,83 x 10-7. The use of raw materials has also changed from its initial design which was using a mixture of copper and brass with a thickness of 0,8 mm to an alternative design by using a mixture of copper and brass with a thickness of 0,5 mm. In addition, the study showed that product C are more preferable for consumers. Keywords: decorative lighting, product development, pairwise comparison, value engineering

Abstract:
Feelings and impressions of a product are important for the decision of purchasing it or not. Designing attractive products therefore requires knowledge about the feelings and impressions the products evoke on the customer and the user. Integrating such affective values in product design requires the introduction of suitable methods into companies’ product design processes, methods which can capture and convert subjective and even unconscious feelings about a product into concrete design parameters. This is sometimes referred to as ‘Affective Engineering’. One methodology in this context is Kansei Engineering, which has been developed in Japan in order to design feelings into products. The aim of this thesis was twofold: Firstly, to improve understanding of the nature of products making emotional impact on the users and customers. Secondly, to identify and improve methods capable of grasping those affective values and translating them into concrete product design solutions. This thesis presents three empirical studies and two methodological papers, relating to warehouse trucks and laminate flooring. The first study was made on user impact of warehouse trucks in three different European countries. A second study dealt with affective values of rocker-switches in work vehicles, such as warehouse trucks. A third study on this truck type compared the old manoeuvring panel evaluated in the previous studies with a newly introduced manoeuvring panel in order to validate the impact of the design improvements made after the first study. Further, a conceptual model on Kansei Engineering methodology was proposed in a methods paper based on the experience from the studies performed in order to provide a structure for performing Kansei Engineering studies. The fifth paper had the purpose of validating and improving the proposed model using laminate flooring as research object. More structured ways of identifying design parameters and relevant product properties was given high priority in the improvement work of the methodology. A model for spanning the Space of Product Properties was presented and applied. This thesis also deals with other improvement areas in the methodology and proposed new developments, including the use of scales, experimental design and validation methods. In conclusion, Kansei Engineering is a concept and a methodology in strong development, a framework in which tools and methods are continuously developed, added and integrated.

Abstract:
The introduction of concurrent engineering has led to a need to perform product development tasks with reduced information detail. Decisions taken during the early design stages will have the greatest influence on the cost of manufacture. The manufacturing requirements for alternative design options should therefore be considered at this time. Existing tools for product manufacture assessment are either too detailed, requiring the results of detailed design information, or too abstract, unable to consider small changes in design configuration. There is a need for an intermediate level of assessment which will make use of additional design detail where available, whilst allowing assessment of early designs. This thesis develops the concept of aggregate process planning as a methodology for supporting concurrent engineering. A methodology for performing aggregate process planning of early product designs is presented. Process and resources alternatives are identified for each feature of the component and production plans are generated from these options. Alternative production plans are assessed in terms of cost, quality and production time. A computer based system (CESS, Concurrent Engineering Support System) has been developed to implement the proposed methodology. The system employs object oriented modelling techniques to represent designs, manufacturing resources and process planning knowledge. A product model suitable for the representation of component designs at varying levels of detail is presented. An aggregate process planning functionality has been developed to allow the generation of sets of alternative plans for a component in a given factory. Manufacturing cost is calculated from the cost of processing, set-ups, transport, material and quality. Processing times are calculated using process specific methods which are based on standard cutting data. Process quality cost is estimated from a statistical analysis of historical SPC data stored for similar operations performed in the factory, where available. The aggregate process planning functionality has been tested with example component designs drawn from industry.

Abstract:
Collaborative products are created when physical components from two or more products are temporarily recombined to form another product capable of performing entirely new tasks. The method for designing collaborative products is useful in developing products with reduced cost, weight, and size. These reductions are valued in the developing world because collaborative products have a favorable task-per-cost ratio. In this paper, a method for designing collaborative products is introduced. The method identifies a set of products capable of being recombined into a collaborative product. These products are then designed to allow for this recombination. Three examples are provided to illustrate the method. These examples show that a collaborative block plane, apple peeler, and brick press, each created from a set of products, can increase the task-per-cost ratio of these products by 42%, 20%, and 30%, respectively. The author concludes that the method introduced herein provides a new and useful tool to design collaborative products and to engineer products that are valued in the developing world.

Engineering simulation models, industrial design form models, and physical experimentation through prototypes are critical elements of successful product design. However, the three disciplines are disconnected and the direction of simulations, form models, and physical prototypes often diverge increasingly as product detail is developed. This divergence often results in an expensive and time consuming design cycle and inferior product quality. The first 10% of the cycle is taken up largely by conceptual design, an iterative stage that requires close interaction between industrial designers, modelers and engineers. In the current state of the art, information is often lost when models are approximately reconstructed from physical prototypes, CAD or surface models. A new approach to the conceptual design cycle is developed and applications for the design of consumer products are discussed. The tools that make up the cycle work together to create a flexible, iterative design environment. Industrial designers, engineers, and modelers generate and exchange form concepts, alternating between physical and digital representations of product geometry. Rapid alternation between the physical and digital domain is enabled and information flow between iterations is improved.

Inspired by bicycle training rollers, a wheelchair exercise roller (an exercise machine for the application of wheelchair users) was designed from conception of idea to alpha prototype. Background and market data was gathered through research with disabled people, members of disability and rehabilitation centers, and by examining other existing related products. Initial designs were created, and using these designs, functional requirements were set. These functional requirements were used to determine the main product modules (rollers, frame, and ramp) and desired features (simulated natural inertia/forces, varying resistance, tilt feature, etc.) Keeping these in consideration, initial calculations and hands-on research were performed in particular to determine the effect of radial load and RPMs on the bearings. Then, by using test modules built with inline skate bearings, aluminum tube, and wood 2"x 4"s, the initial calculations and research were tested. The results of these tests helped to determine the eventual final design. Solid modeling software (Solidworks 2005) was then used to create various design iterations and make changes as needed.
(cont.) Finally, using the final solid model, a functional prototype was built using 2"x 2" aluminum angle, conveyor belt rollers, and plywood. This prototype was then tested under the conditions the product was originally intended to function under. The result of these tests showed that in the current state, the prototype was not at a level ready to be marketed. The rollers in their current state did not fully simulate the natural inertia and forces felt when rolling on real ground. Also, several desired features had not yet been implemented. However, the prototype did succeed in ultimately showing potential functionality and feasibility of the product.

A Product Design and Manufacturing (PDM) Engineering emphasis has been designed to update a Manufacturing Engineering program at Grand Valley State University. While the program continues to include a major focus on manufacturing it also emphasizes crossing disciplinary boundaries for product design. Graduates of the program are educated to work in all phases of the product development process from concept to customer. The program includes a blend of courses from a variety of disciplines, tieing these together using a sequence of product design courses. Within the courses students are exposed to course work that encourages product oriented design including prototyping. The program redesign described in the paper could also be applied to Mechanical Engineering programs.

Abstract:
This is a position paper. Although modular design is getting wide attention these days, most of the discussions and applications are focused on efficiency, cost reduction, etc., which has been regarded important in the traditional product development or in the producer’s framework. Their focus is how they can prepare wider variety with less time, money and energy. They believe if a wide variety of products are offered. the customer would select the one that would fit them best. Thus, not too much attention is paid to the customer expectations. The current producer do not sell dreams. They just increases the choices. This can be compared to what animals are doing. Animals can use tools, but these tools are found in nature. Animals do not make tools, but humans do, because humans can see the future, while animals cannot. Engineering is an activity to satisfy customer dreams. In this sense, the current industry is not achieving what engineering is supposed to achieve. In addition, as human needs step up, humans would like to actualize themselves. But in the earlier or lower step, their needs are products so products satisfy them. But when they step more and more upward, they find value in the processes. So products alone will not satisfy them enough. They would like to make their dreams come true by themselves. Thus, how we can get customers involved in the production becomes important. In short, we have to consider how we can mix high tech and low tech and work them harmoniously. Some modules needs high tech. Thus expertise is needed. But others can be developed and produced by customers. Then, customers will be very happy because they are players in the game and they feel they themselves are developing a product to realize their own dream. Of course, personal fabrication technology can be used for this purpose. But theirs and my idea are basically different. Their idea is to produce a product by ourselves. But the approach proposed here is focused on our industrial products. The issue here is how we can bring our customers into our product development, which current industries are practicing. If we can design a product, which is composed of modules which needs high tech and expertise and those which can be produced with low tech, then we can bring our customers into low tech and low expertise module production. Although customers are not producing the whole product, they feel happier because they are now making their dream come true themselves. Thus, industries can sell processes. And it should be stressed that this is not a reconfigurable design. The low tech and low expertise modules are really produced by our customers. They do not select modules to produce a product as we do with Lego. This design of mixture of low tech module and high tech module serves for globalization as well. Some developing countries cannot produce high tech modules, because their resources are not enough. But if some modules can be produced with low tech, then they can produce them locally and that will increase employment and the market will expand.

Abstract:
The aim of this paper is to propose a framework to guide engineers’ use of LCA tools to optimize three important stages of a product’s life cycle. The three phases are product concept design, manufacturing process and products end of life recycle. A mountain bike has been used as an example to demonstrate how engineers are guided by the proposed framework. The proposed framework does not only lead industry in a sustainable design direction but also guide them to embed sustainable thinking into every stage of a product life cycle based on their existing resources. Some design tools and techniques have been incorporated with life cycle assessment tools to achieve the sustainable optimization of the products.

Abstract:
Abstract Product architecture can have a significant impact on a product’s life-cycle and its development time. Modular product architecture allows for easy disassembly upon product retirement and allows for wide product variety. In a small company, the team structure of the company can correspond to the modules, and modules can be used across product lines. By using similar modules from one generation to the next, product development time can be reduced. The methodology described in this paper gives a small company the framework from which to develop modular products.

Abstract:
Abstract Traditional engineering analysis of product designs has focused primarily on a product’s operational performance without considering costs of manufacturing and other stages downstream from design. In contrast, life cycle analysis of a product during its initial development can play a crucial role in determining the product’s overall life cycle cost and useful life span. This paper examines product life cycle engineering analysis - measurement of product operational performance in a life cycle context. Life cycle engineering analysis is thus considered both as an extension of traditional engineering analysis methods and as a subset of a total product life cycle analysis. The issues critical to life cycle engineering analysis are defined and include product life cycle data modeling and analysis, analysis tools and their performance regimes, performance tradeoff measurement and problems of life cycle engineering analysis in an organizational context. Recommendations are provided for future research directions into life cycle engineering analysis in the context of integration architectures for concurrent engineering.

Abstract:
Abstract This paper reports research on approaches for accessing and controlling product data within the Product Introduction Process (PIP) through the specification, prototyping, and integration of a set of product structures, product viewpoints and their relationships. A significant achievement has been the validation of a collection of computer-based models of product structures that enable the capture of work breakdown, product specification, product functionality, and the physical parts that comprise the product. Furthermore, a number of relationships between these product structures and the business processes that use and create them have been identified. The work presented in this paper demonstrates the importance of representing relationships between product introduction processes and products through the adoption of product structures. The potential for exploiting product structures to improve understanding of relationships between products and processes is illustrated. A case study captures flows of related functional and physical product structures within PIPs across a two-tier supply chain, and discusses the issues involved in supporting such related product and process information.

Abstract:
Cross-disciplinary technologies are noticeable phenomena in modern products, as found in renewable energy and electric vehicle industries. However, current conceptual design tools have been limited to respond these cross-disciplinary technology products. One of remarkable characteristics in this technology change is transforming an existing product with multiple cross-disciplinary technologies. This paper presents a new product design paradigm, called Transformative Product Design (TPD), to respond this phenomenon. In TPD, transformation is a design process to produce a new product (i.e., transformative product) from a base product by adding and/or converting functions/features with reference products or technologies. To accomplish the transformation process, this paper develops a new Functional Concept-based Detection method. Also, the proposed functional concept-based detection method is described with a case study in the context of transformative product design process.

Abstract:
Consumer product design blends engineering and industrial design principles, and marketing strategies to bring functional, aesthetic products to market. While competitions motivate a diverse set of students to churn out products/ventures, a systematic approach for tackling consumer product design tasks and case studies that demonstrate the approach greatly benefit a number of students by focusing their design efforts. The paper elaborates such an approach using a case study highlighting the thought process. The case study involves the design of an innovative keychain. While the case study was primarily mechanical engineering in scope addressed by a student team of mechanical engineers, the approach outlined in the paper is generic and can be applied to product designs involving other disciplines.

Abstract:
Abstract In an effort to produce more variety for today’s highly competitive market, companies are designing and developing families of products — groups of related products derived from common product platforms — to simultaneously satisfy multiple customer requirements. After reviewing the state of the art in product family and product platform design, we describe the Product Platform Concept Exploration Method (PPCEM) for designing common product platforms that can be scaled or “stretched” into a suitable family of products. This paper extends previous work by the authors through the novel integration of physical programming within the PPCEM to enable the product family design problem to be formulated using physically meaningful terms and preferences. The design of a family of universal electric motors is presented to demonstrate the effectiveness of the proposed approach. Performance gains are achieved in the motor family by utilizing physical programming within the PPCEM when compared to previous results.

Abstract:
Technological innovations in sanitation are poised to address the great need for sanitation improvements in low-income countries. Worldwide, more than 2.4 billion people lack access to improved sanitation facilities. Innovative waste treatment and sanitation technologies aim to incorporate user-centered findings into technology engineering and design. Without a focus on users, even the most innovative technology solutions can encounter significant barriers to adoption. Drawing on a household survey conducted in urban slum communities of Ahmedabad, India, this research brief identifies toilet and sanitation preferences, amenities, and attributes that might promote adoption of improved sanitation technologies among potential user populations. This work uses supplemental insights gained from focus groups and findings from the literature. Based on our research, we offer specific guidance for engineering and design of sanitation products and technologies.

Abstract:
The original objectives are listed below: 1. Design vectors for constitutive expression of endochitinase from Trichoderma harzianum strain P1. Design vectors with signal peptides to target gene expression. 2. Extend transformation/regeneration technology to other cultivars of importance in the U.S. and Israel. 3. Transform cultivars with the endochitinase constructs developed as part of objective 1. A. Characterize foliar powdery mildew resistance in transgenic plants. Background of the topic Conventional breeding of grapevines is a slow and imprecise process. The long generation cycle, large space requirements and poor understanding of grapevine genetics prevent rapid progress. There remains great need to improve existing important cultivars without the loss of identity that follows from hybridization. Powdery mildew (Uncinula necator) is the most important fungal pathogen of grapevines, causing economic losses around the world. Genetic control of powdery mildew would reduce the requirement for chemical or cultural control of the disease. Yet, since the trait is under polygenic control, it is difficult to manipulate through hybridization and breeding. Also, because grapevines are heterozygous and vegetatively propagated cultivar identity is lost in the breeding process. Therefore, there is great need for techniques to produce transgenic versions of established cultivars with heterologous genes conferring disease resistance. Such a gene is now available for control of powdery mildew of grapevines. The protein coded by the Endochitinase gene, derived from Trichoderma harzianum, is very effective in suppressing U. necator growth. The goal of this proposal is to develop transgenic grapevines with this antifungal gene, and to test the effect of this gene on resistance to powdery mildew. Conclusions, achievements and implications Gene transfer technology for grape was developed using commercial cultivars for both wine and table grapes. It paved the way for a new tool in grapevine genetic studies enabling the alteration of specific important traits while maintaining the essential features of existing elite cultivars. Regeneration and transformation technologies were developed and are currently at an advanced stage for USA wine and Israeli seedless cultivars, representing the cutting edge of grape genetic engineering studies worldwide. Transgenic plants produced are tested for powdery mildew resistance in greenhouse and field experiments at both locations. It is our ultimate goal to develop transgenic grapes which will be more efficient and economical for growers to produce, while also providing consumers with familiar products grown with reduced chemical inputs.

Full text
Abstract:
This Coastal and Hydraulics Engineering Technical Note (CHETN) describes the design and implementation of a wave model evaluation system, altWIZ, which uses wave height observations from operational satellite radar altimeters. The altWIZ system utilizes two recently released altimeter databases: Ribal and Young (2019) and European Space Agency Sea State Climate Change Initiative v.1.1 level 2 (Dodet et al. 2020). The system facilitates model evaluation against 1 Hz1 altimeter data or a product created by averaging altimeter data in space and time around model grid points. The system allows, for the first time, quantitative analysis of spatial model errors within the U.S. Army Corps of Engineers (USACE) Wave Information Study (WIS) 30+ year hindcast for coastal United States. The system is demonstrated on the WIS 2017 Atlantic hindcast, using a 1/2° basin scale grid and a 1/4° regional grid of the East Coast. Consistent spatial patterns of increased bias and root-mean-square-error are exposed. Seasonal strengthening and weakening of these spatial patterns are found, related to the seasonal variation of wave energy. Some model errors correspond to areas known for high currents, and thus wave-current interaction. In conjunction with the model comparison, additional functions for pairing altimeter measurements with buoy data and storm tracks have been built. Appendices give information on the code access (Appendix I), organization and files (Appendix II), example usage (Appendix III), and demonstrating options (Appendix IV).

Pacific Earthquake Engineering Research Center, University of California, Berkeley, CA, November 2020. http://dx.doi.org/10.55461/svks9397.

Full text
Abstract:
Considering the importance of the transportation network and bridge structures, the associated seismic design philosophy is shifting from the basic collapse prevention objective to maintaining functionality on the community scale in the aftermath of moderate to strong earthquakes (i.e., resiliency). In addition to performance, the associated construction philosophy is also being modernized, with the utilization of accelerated bridge construction (ABC) techniques to reduce impacts of construction work on traffic, society, economy, and on-site safety during construction. Recent years have seen several developments towards the design of low-damage bridges and ABC. According to the results of conducted tests, these systems have significant potential to achieve the intended community resiliency objectives. Taking advantage of such potential in the standard design and analysis processes requires proper modeling that adequately characterizes the behavior and response of these bridge systems. To evaluate the current practices and abilities of the structural engineering community to model this type of resiliency-oriented bridges, the Pacific Earthquake Engineering Research Center (PEER) organized a blind prediction contest of a two-column bridge bent consisting of columns with enhanced response characteristics achieved by a well-balanced contribution of self-centering, rocking, and energy dissipation. The parameters of this blind prediction competition are described in this report, and the predictions submitted by different teams are analyzed. In general, forces are predicted better than displacements. The post-tension bar forces and residual displacements are predicted with the best and least accuracy, respectively. Some of the predicted quantities are observed to have coefficient of variation (COV) values larger than 50%; however, in general, the scatter in the predictions amongst different teams is not significantly large. Applied ground motions (GM) in shaking table tests consisted of a series of naturally recorded earthquake acceleration signals, where GM1 is found to be the largest contributor to the displacement error for most of the teams, and GM7 is the largest contributor to the force (hence, the acceleration) error. The large contribution of GM1 to the displacement error is due to the elastic response in GM1 and the errors stemming from the incorrect estimation of the period and damping ratio. The contribution of GM7 to the force error is due to the errors in the estimation of the base-shear capacity. Several teams were able to predict forces and accelerations with only moderate bias. Displacements, however, were systematically underestimated by almost every team. This suggests that there is a general problem either in the assumptions made or the models used to simulate the response of this type of bridge bent with enhanced response characteristics. Predictions of the best-performing teams were consistently and substantially better than average in all response quantities. The engineering community would benefit from learning details of the approach of the best teams and the factors that caused the models of other teams to fail to produce similarly good results. Blind prediction contests provide: (1) very useful information regarding areas where current numerical models might be improved; and (2) quantitative data regarding the uncertainty of analytical models for use in performance-based earthquake engineering evaluations. Such blind prediction contests should be encouraged for other experimental research activities and are planned to be conducted annually by PEER.

Full text
Abstract:
This Coastal and Hydraulics Engineering Technical Note (CHETN) describes the continuing efforts towards incorporating rapid tidal time-series reconstruction and prediction capabilities into the Coastal Hazards System (CHS) and the Stochastic Storm Simulation System (StormSim). The CHS (Nadal-Caraballo et al. 2020) is a national effort for the quantification of coastal storm hazards, including a database and web tool (https://chs.erdc.dren.mil) for the deployment of results from the Probabilistic Coastal Hazard Analysis (PCHA) framework. These PCHA products are developed from regional studies such as the North Atlantic Coast Comprehensive Study (NACCS) (Nadal-Caraballo et al. 2015; Cialone et al. 2015) and the ongoing South Atlantic Coast Study (SACS). The PCHA framework considers hazards due to both tropical and extratropical cyclones, depending on the storm climatology of the region of interest. The CHS supports feasibility studies, probabilistic design of coastal structures, and flood risk management for coastal communities and critical infrastructure. StormSim (https://stormsim.erdc.dren.mil) is a suite of tools used for statistical analysis and probabilistic modeling of historical and synthetic storms and for stochastic design and other engineering applications. One of these tools, the Coastal Hazards Rapid Prediction System (CHRPS) (Torres et al. 2020), can perform rapid prediction of coastal storm hazards, including real-time hurricane-induced flooding. This CHETN discusses the quantification and validation of the Advanced Circulation (ADCIRC) tidal constituent database (Szpilka et al. 2016) and the tidal reconstruction program Unified Tidal analysis (UTide) (Codiga 2011) in the Puerto Rico and U.S. Virgin Islands (PR/USVI) coastal regions. The new methodology discussed herein will be further developed into the Rapid Tidal Reconstruction (RTR) tool within the StormSim and CHS frameworks.

Full text
Abstract:
An electronic sensory system for the evaluation of headspace volatiles was developed to determine fruit ripeness and quality. Two prototype systems were designed, constructed, and later modified. The first is an improved version of our original prototype electronic sniffer using a single head sensing unit for use as a single or paired unit placed on an individual fruit surface for applications in the field, lab, or industry. The second electronic sniffer utilizes a matrix of gas sensors, each selected for differential sensitivity to a range of volatile compounds. This system is more sophisticated as it uses multiple gas sensors, but was found to enhance the ability of the sniffer to classify fruit ripeness and quality relative to a single gas sensor. This second sniffer was designed and constructed for the sampling of fresh-cut or whole packs of fruits such as packaged strawberries and blueberries, and can serve as a prototype for research or commercial applications. Results demonstrate that electronic sensing of fruit ripeness based on aromatic volatile gas emissions can be used successfully with fresh frits. Aroma sensing was successful for classifying ripeness in muskmelons, including different cultivars, apples, blueberries, strawberries, and in a complimentary BARD project on tomatoes. This system compared favorably to the physicochemical measurements traditionally employed to assess fruit maturity. This nondestructive sensory system can detect the presence of physically damaged fruits and shows excellent application for use in quality assessment. Electronic sensors of the tin oxide type were evaluated for specificity toward a wide range of volatiles associated with fruit ripeness. Sensors were identified that detected a broad range of alcohols, aldehydes, esters, hydrocarbons, and volatile sulfur compounds, as well as individual volatiles associated with fruit ripening across a wide concentration range. Sensors are not compound specific, thus, the matrix of sensors coupled with discrimination analysis provides a fingerprint to identify the presence of compounds and to assess alterations in fresh products due to alterations in volatile emissions. Engineering developments led to the development of a system to compensate for temperature and relative humidity relative to on-line aroma sensing with melons for ripeness determination and to reduce response time, thus permitting the electronic sniffer to be used for monitoring both fresh and processed food products. The sniffer provides a fast, reliable and nondestructive tool to assess fruit ripeness and quality. We hope that our work will foster the introduction and utilization of this emerging technology into the agricultural and horticultural

Full text
Abstract:
This interdisciplinaray work combines expertise in engineering and entomology in Israel and the US, to develop an acoustic trap for mate-seeking female medflies. Medflies are among the world's most economically harmful pests, and monitoring and control efforts cost about $800 million each year in Israel and the US. Efficient traps are vitally important tools for medfly quarantine and pest management activities; they are needed for early detection, for predicting dispersal patterns and for estimating medfly abundance within infested regions. Early detection facilitates rapid response to invasions, in order to contain them. Prediction of dispersal patterns facilitates preemptive action, and estimates of the pests' abundance lead to quantification of medfly infestations and control efforts. Although olfactory attractants and traps exist for capturing male and mated female medflies, there are still no satisfactorily efficient means to attract and trap virgin and remating females (a significant and dangerous segment of the population). We proposed to explore the largely ignored mechanism of female attraction to male song that the flies use in courtship. The potential of such an approach is indicated by studies under this project. Our research involved the identification, isolation, and augmentation of the most attractive components of male medfly songs and the use of these components in the design and testing of traps incorporating acoustic lures. The project combined expertise in acoustic engineering and instrumentation, fruit fly behavior, and integrated pest management. The BARD support was provided for 1 year to enable proof-of-concept studies, aimed to determine: 1) whether mate-seeking female medflies are attracted to male songs; and 2) over what distance such attraction works. Male medfly calling song was recorded during courtship. Multiple acoustic components of male song were examined and tested for synergism with substrate vibrations produced by various surfaces, plates and loudspeakers, with natural and artificial sound playbacks. A speaker-funnel system was developed that focused the playback signal to reproduce as closely as possible the near-field spatial characteristics of the sounds produced by individual males. In initial studies, the system was tasted by observing the behavior of females while the speaker system played songs at various intensities. Through morning and early afternoon periods of peak sexual activity, virgin female medflies landed on a sheet of filter paper at the funnel outlet and stayed longer during broadcasting than during the silent part of the cycle. In later studies, females were captured on sticky paper at the funnel outlet. The mean capture rates were 67 and 44%, respectively, during sound emission and silent control periods. The findings confirmed that female trapping was improved if a male calling song was played. The second stage of the research focused on estimating the trapping range. Initial results indicated that the range possibly extended to 70 cm, but additional, verification tests remain to be conducted. Further studies are planned also to consider effects of combining acoustic and pheromonal cues.
