The new generation of value-added low carbon-low manganese-niobium microalloyed structural steels for both low and high yield strength, energy absorption, fatigue and fracture resistant applications is under development for offshore and arctic materials engineering applications. These materials engineering considerations are shifting designers to consider new lower cost and more robust construction materials even for low yield strength applications require improved fatigue, fracture arrest and toughness performance. The civil engineering and end user community demand structural reinforcing bars, shapes, beams and plates with improved energy absorption and fatigue properties. With more severe climatic conditions evolving every day, demands also necessitate improved fire and seismic resistance, yield-to-tensile ratio consistency, improved bendability and weldability. These attributes are difficult to obtain from steel producers today with their current higher carbon microalloyed steel approaches and hot rolling practices. There is a global shift in motion to low C-Nb-Mn bearing construction steels displacing traditional materials. The technological and metallurgical advancements of value-added niobium (Nb) microalloyed thermo-mechanical controlled process (TMCP) plate steels have been further developed to meet more demanding fatigue, fracture and low temperature toughness end user requirements. Niobium enables achievement of substantial grain refinement and grain size uniformity when the plate is rolled with the proper reduction, thermal schedule and process metallurgical operational practices. The effects of microalloying elements on the continuous cooling transformation behavior must be carefully controlled during the process metallurgy of the reheating and rolling process to successfully achieve the desired mechanical properties. TMCP applications have been successfully developed in numerous product sectors with thickness exceeding 120 mm. Since the very fine grained microstructure improves toughness and increases the yield strength, this Nb-TMCP process enables the required tensile properties with the growing trend to leaner chemical composition designs (less than 0.10%C) and excellent toughness properties. From an operational cost perspective, in today’s very competitive market environment, there exists a huge opportunity for structural offshore and arctic plate producing steel mills to improve their profitability by thoroughly assessing a shift to lower carbon and manganese steels in their product mix. Through the adoption of these lower carbon Nb-containing structural materials, several design and/or manufacturing companies are initiating new offshore steel designs that will further provide improved overall lifetime and cost performance at reduced maintenance expense. These high strength plate steels offer the opportunity to manufacture complex heavy-lift and fatigue-critical components for larger offshore structures without increasing the weight of the platforms.

In this paper we analyze the changes of the EU’s investment policy provoked by the mixed trade agreements. The EU’s investment policy has turned towards attaining bilateral trade agreements. One of these “new-generation” agreements is the Comprehensive Economic and Trade Agreement (CETA). It is in a process of being ratified by the national parliaments of the EU members. This study is focused on the general characteristics of CETA and the eventual problems posed by its regulatory and wide-ranging nature. We prove that the significance of this agreement pertains not only to the economic influence, that it will have on the European and Canadian economies, but CETA is also the first trade agreement to have been negotiated with a focus on investment protection and a change in the EU’s investment policy. The current study reveals the influence arising from the conclusion of CETA on the Bulgarian economy with an emphasis on electronic industry, machinery industry and manufacturing. We estimate both – the direct and indirect effects on Bulgaria’s exports, imports, value added and employment. In order to estimate the influence, we apply the multi-regional input-output model. It is proved that CETA will have a low but positive impact on the Bulgarian economy. After constructing different scenarios of development, we prove that the influence of CETA on the Bulgarian economy will amount to 0.010% GDP. The average total employment will be increased by more than 172 jobs in Bulgaria, which in turn, relative to the labor market, represents less than 0.01% of the total employment.

This study introduces the opinion of the corrugation hierarchy to develop the second-order corrugation paperboard, and explore the deformation characteristics, yield strength, and energy absorbing capacity under out-of-plane static evenly compression loading by experimental and analytical approaches. On the basis of the inclined-straight strut elements of corrugation unit and plastic hinge lines, the yield and crushing strengths of corrugation unit were analyzed. This study shows that as the compressive stress increases, the second-order corrugation core layer is firstly crushed, and the first-order corrugation structures gradually compacted until the failure of entire structure. The corrugation type has an obvious influence on the yield strength of the corrugation sandwich panel, and the yield strength of B-flute corrugation sandwich panel is wholly higher than that of the C-flute structure. At the same compression rate, the flute type has a significant impact on energy absorption, and the C-flute second-order corrugation sandwich panel has better bearing capacity than the B-flute structure. The second-order corrugation sandwich panel has a better bearing capacity than the first-order structure. The static compression rate has little effect on the yield strength and deformation mode. However, with the increase of the static compression rate, the corrugation sandwich panel has a better cushioning energy absorption and material utilization rate.

AbstractDP980 steels were joined using fiber laser welding. The welded joint was characterized in terms of hardness distribution and tensile behavior at room temperature, 150 ℃, and 300 ℃, respectively. The fine-grained martensite in supercritical heat affected zone (HAZ) resulted in the highest hardness (428 Hv), while the tempered martensite contributed to the hardness decreasing (‒31 Hv). Both the ultimate tensile strength and yield strength of the base metal and welded joint decreased at 150 ℃, and then increased at 300 ℃ due to dynamic strain aging (DSA). The welded joint exhibited slightly higher yield strength and lower elongation at all the test temperatures compared to base metal due to the hardened fusion zone. The energy absorption reduced slightly with increasing temperature both for base metal and welded joint, and the weld posed a minor effect on the energy absorption. Deformation was one of the requirements for DSA effect. DSA enhanced the hardness of base metal (+78 Hv) and softened zone (+53 Hv). HAZ was not softened enough to become the weakest position during tensile test.

Purpose – The purpose of this paper is to sketch a comparative account of NPD approaches between registered New Zealand food companies that are doing some sort of functional foods (FF) development (Group 1) and those that are not (Group 2); to generate a better understanding of differences and commonalities in their NPD approaches from resource-based view of competitive advantage. Design/methodology/approach – This paper opted an exploratory approach using a quantitative survey across food manufacturing companies in New Zealand. The primary foci of this empirical investigation were: orientation towards the NPD, innovation processes, collaborative NPD links and routes to commercialisation. Findings – The results (based on a 22 per cent response rate) show a significant difference (p<0.05) in the aims and mode of NPD between Groups 1 and 2. Further it was observed that food companies in Group 1 have significantly (p<0.05) more diverse external collaborations with broader aims to collaborate, in comparison with food companies in Group 2. Research limitations/implications – This study was conducted in New Zealand and thus generalisability of the findings may have to be interpreted carefully. Practical implications – The traditional NPD approach (independent and closed NPD), with loose intellectual property protection practices, dominates the food manufacturing industry in New Zealand. Research-oriented collaborations need to be strengthened in their scope and content to develop the innovative capabilities and capacities of small and medium enterprises (SME's) within future value-added food productions. Originality/value – This research provides the comparative narration of innovation process of food manufacturing companies with reference to FFs development.

For decades, digital systems have been designed based on assumptions that the underlying hardware, though not perfectly reliable, is free of malicious elements. The demand for IC’s is greatly increasing due to tremendous technological development. Without appropriate resources the companies are hard pressed to produce trusted IC’s. This is driving the companies into the ‘fabless’ trend predominant in semiconductor industry, where the companies are depending on cheaper foundries for the IC fabrication instead of depending on their own resources. This growth brings with it a big rise in threat level in terms of Hardware Trojans that hits the manufacturing companies which make use of Integrated Circuits. This transcends many industries, including strategic organizations and telecommunication companies, mobile phones and computers, embedded systems used in domestic applications and health care equipment. These adversarial inclusions are generally triggered to do malicious modifications in the end user system by the intruder, which is difficult to detect in their quiescent state. This paper focuses on understanding Hardware Trojans, their implications and detection methodologies. It is extremely important for all industries and more so for defense organizations, who are involved in developing systems to protect the nation’s boundaries.

The Internet Of Things

Now the Internet of Things (IoT) is growing fast into a large industry with huge potential economic impact expected in near future. The IoT technology evolves to a substrate for resource interconnection and convergence. The users' needs go beyond the existing web-like services, which do not provide satisfactory coupling and automatic composition when the user tries to solve tasks from her/his everyday life. New generation of services (named “smart services”) emerges. In this chapter, we introduce the problem of effective use of the multitude of IoT-enabled devices and other digital resources that now surround our lives. The devices support and assist human by provision of digital services. This is the key objective of a smart environment. Our focus is on such a particular class of smart environments as smart spaces. This class targets IoT-enabled computing environments, where a smart space is created and then provides an infrastructure for applications to construct and deliver value-added services based on cooperative activity of environment participants, either human or machines.

The business landscape has changed dramatically in recent years. Innovative organisations are restructuring their business models. They are moving away from discrete linear value chains towards open innovation models such as networks. Small to Medium Sized Enterprises (SMEs) recognise that in order to survive they must be equipped with the relevant competencies required to design, develop and deploy innovative solutions that meet the needs of the end user. More and more small firms are collaborating with each other in order to create value added products and access new markets. However, the task of working in a collaborative network is not easy. SMEs find it particularly difficult to engage in these activities and experience many challenges in this regard. Moreover, there are very few support structures and systems available to guide successful knowledge sharing and collaboration. This chapter explores the fundamental concepts of collaborative networks and knowledge sharing, synthesises and presents some of the challenges faced by SMEs and identifies some critical success factors that should be considered to help overcome the barriers identified.
