The purpose of this paper is to verify the performance and function of the scale-up prototypes by predicting the material and energy consumption on the basis of dimension-reduced prototypes. Additive manufacturing (AM) costs determine carbon emissions in total life cycle, among which material and energy consumption are major components. Predicting material and energy consumption is fundamental to reducing costs.

This paper presents a material and energy co-optimization method for AM via multiple layers prediction (MLP). Material and energy consumption are predicted to reduce the AM costs. In particular, scalable, complex curved surface component is used to improve forecasting efficiency. Subsequently, the back pressure distribution is obtained by scale-up specimens, which can lay the foundation for the ergonomic conceptual design.

Taking evolutionary ergonomic product as an example, the relative gravity direction of backrest is calculated. The material and energy consumption are predicted with low deviation. Physical experiments were carried out to validate information. Digital and physical tests have revealed that material and energy co-optimization improves manufacturing efficiency.

The innovatively proposed MLP method predicts material and energy consumption of scale-up prototypes to reduce the costs. It is propitious to improve the carbon emission efficiency in life cycle of AM. The originality may be widely adopted alongside increasing environmental awareness.

Every company engaged in the development of new products can expect some failures. Since each successive stage of development increases in cost by roughly ten times, the cost of failure can be greatly reduced if fatal flaws are recognized early, and doomed projects are aborted before they waste a firm's resources. By subjecting a developing product to a periodic review of its status, management can assess whether or not it is worth continued funding. The technological aspects of the potential product must be scrutinized carefully for, while products fail to be commercial for many reasons, technical flaws invariably lead to dead ends.

The paper aims to describe recent moves to establish a UK electronic thesis service. The existing arrangements for access to UK doctoral theses are not seen as ideal or sustainable. A range of stakeholders have come together in recent years to invest in an alternative. The resulting service model is one that is relevant to higher education across the UK and beyond.

The EThOS service model is a partnership between the British Library as the service provider and UK universities, and includes technical, legal, business and operational aspects. It has been achieved by a series of development projects undertaken since 2002, culminating now in the impending transition from prototype to live service.

The EThOS service model includes a range of partnership options to suit the varied requirements of UK higher education institutions. The main ambition of the model is to make electronic theses available open access via a financially viable and sustainable model. The core of the model is a “central hub”, offering discovery, digitisation and preservation functions, working with institutions, in part via their institutional repositories.

It is hoped that most UK higher education institutions will sign up for EThOS and benefit from this shift to both electronic theses and open access. Many have already indicated that they will do so.

The value of the EThOS service is likely to be considerable. Where theses are available open access, their use escalates. EThOS will enable UK theses to be more widely accessed, read, used and cited worldwide. Authors, institutions and the UK all benefit from this.

The purpse of this study is to examine sustainable technology development (STD) during the “Valley of Death” phase encountered by university startups undertaking intellectual property rights (IPR) commercialisation.

A comprehensive literature review was conducted after searching for relevant documents across multiple databases. Semi-structured interviews with university startup founders were also conducted as part of a qualitative case study.

This study resulted in two significant findings. First, the Valley of Death has been redefined in the specific context of IPR commercialisation by university startups. Second, the sustainable technology development framework (STDF) has been conceptualised to enhance the success rate of IPR commercialisation by university startups. The authors also identified three essential components of STD in the context of university startups: market development, technical efficiency and business sustainability.

This exploratory research involved a thorough literature analysis. Given that only one qualitative case study was conducted, data saturation was not achieved. Further empirical research is needed to validate the conceptualised STDF.

The validated STDF will be a useful tool for enhancing the success of IPR commercialisation by university startups.

While others have focused on innovating business models, this study focused on an underexplored area: the sustainability of technology development during the commercialisation of IPR by university startups during the Valley of Death phase.

This study aims to develop our understanding of the value co-creation process in business networks. This study identifies four key sub-processes that characterize the value co-creation journey as it unfolds across an inter-organizational network. These four sub-processes are opportunity co-creation, solution co-creation, complementary co-creation and activated co-creation.

Reflecting the exploratory nature of this research, the methodology relies on an in-depth case study, which is analyzed through the lens of the resource interaction occurring within the specific business relationships and collaborative episodes that affected the nine-year long development of Deko, a new architectural lighting solution.

The main contribution of the paper is identifying the sub-processes comprising the value co-creation journey of a technology development solution based on resource combining, re-combining and un-combining across a business network. That value co-creation occurs through a time-consuming journey requiring multiple episodes of collaboration can also inspire the practice of handling this process for instance for a small business such as the one featured in this case study.

This paper highlights that the value co-creation journey process has the potential to frame the unfolding of collaboration in practice for a small business.

The purpose of this paper is to develop a concept and design to cast Al alloys/metal matrix composites (MMCs) by continuous casting process. The various steps involved in the evolution of the design have been reported and discussed in this study.

On the basis of developed design concept, initial prototype design has been prepared in this study. The casting process's melt flow pattern was studied via computer simulation, and the resulting changes were implemented in the original design. The single-phase fluid flow pattern through bottom feeding technique is studied. The equipment was fabricated based on computer simulation and water modelling studies. Finally, validation was performed for the preparation of Al alloys/ MMCs after parameter optimisation. The results were observed in the optical metallography to confirm the alloying and Al MMC preparation.

The developed continuous casting process with bottom feeding technique for the addition of constituent particles shows more efficiency in comparison to the existing batch processes. The final manufactured setup demonstrates effective Al alloy/MMC production as the basis for final fabrication has been accomplished by both computer simulation and water model test. In addition, the microstructure exhibits homogeneous distribution, validating the reliability of the setup.

Integrating continuous casting with continuous reinforcement or master alloy addition is novel in this area. The constraints that batch production had that have been rectified will also lower the contemporary cost of production.

A detailed multi‐site study has been undertaken to determine the variation in the positional accuracy of circuit features in the manufacture of large panel High‐Density Interconnect (HDI) printed circuit boards. The imaging stages were particularly referenced when it was shown that photo‐tool variation between 7 sites on 19 different photo‐plotters from 3 manufactures differed by substantially more than the typical HDI design rule. After photo‐plotter optimisation the residual errors between them were commonly of 2 types. It was concluded that the errors introduced in the standard photo‐tooling process were such that it was not possible to produce guaranteed yields on large HDI panels. It has been shown that the use of LDI can reduce costs and speed up the photo‐tooling production process. 3 different LDI machines were evaluated to study the concept of large panel high volume production. One was chosen for a long‐term study which concluded that HDI panels up to 30×24″ could be produced with the accuracy required for HDI designs. The output was approximately 9,000 scans per week but the productivity of circuit boards per panel was substantially improved with the larger panel size. It is feasible to double the throughput with the development of improved handling systems.

This paper bridges the gap between the theory and practice by developing a life cycle sustainability tracker (LCST). The study is seeking to proffer solutions to an observed shortcoming of conventional life cycle sustainability assessment (LCSA) communication platforms. Notably, the static nature of the information provided on such platforms has made it difficult for them to be used for real-time decision-making and predictions. The main aim of this paper is to develop a LCST that facilitates a dynamic visualisation of life cycle sustainability results and allows for an integrated benchmark across the dimensions of sustainability.

The study leverages the model development capabilities of the design science research strategy in accomplishing a dynamic and novel communication platform. A life cycle thinking methodology and appropriate multicriteria decision approach (MCDA) is applied to accomplish a comprehensive, streamlined and replicable approach in mapping and tracking the progress of sustainable development goals (SDGs) in the National Infrastructure Pipeline (NIP) projects in India.

It was found that: (1) The use of the LCST tracker provides a dynamic and holistic insight into the key LCSA indicators with clearly defined benchmarks to assess the impact on the SDG 11, (2) The NIP projects achieve an upward trend across all the regions, and the percentage of opportunities ranges from 11 to 24%, with the South experiencing the highest growth and the North having the minimal increase in percentage and (3) The assessment score (52–58%) provides performance metrics that align well with the LCST – which ranges between “Fair” and “Average” for all the regions in India.

The novelty of this research is that the LCST provides a transparent and harmonised approach to reporting on the LCSA results. The LCST utilises heat maps and radial mapping to achieve an intuitive display of large amounts of highly heterogeneous data, thus allowing the synthesis of large sets of information compactly and with coherence. Progress towards the SDGs change on a yearly basis; hence, a dynamic LCSA tool provides a timely and the valuable context to map and track performance across different regions and contexts.
