Currency security and forensics: a survey

By its definition, the word currency refers to an agreed medium for exchange, a nation’s currency is the formal medium enforced by the elected governing entity. Throughout history, issuers have faced one common threat: counterfeiting. Despite technological advancements, overcoming counterfeit production remains a distant future. Scientific determination of authenticity requires a deep understanding of the raw materials and manufacturing processes involved. This survey serves as a synthesis of the current literature to understand the technology and the mechanics involved in currency manufacture and security, whilst identifying gaps in the current literature. Ultimately, a robust currency is desire

The representation of money in film : gold, paper, metal and electronic

This dissertation is a study of the representation of money on screen, in its textual and contextual constructions. Money, itself a representation, has a complex status: it is both an abstract concept, a symbol of value, a social convention, and a concrete object in its embodiment as gold, metal or paper. This study then is that of a representation of a representation. Its starting point is the very paradox of money as both an object endowed with great value while at the same time not worth much more than the substance it is made of or the numbers referring to it in newer forms of electronic money. The paradox is particularly salient in a medium that works through images while at the same time requiring itself so much money. The distinction between the two Latin words moneta and pecunia offers an understanding of money in its main properties and functions, as an exchange tool in constant circulation and as an object of hoarding, as belongings. This distinction is operative in the present study and runs through the thesis, together with the Marxian concepts of use-value and exchange value. The objective is to analyse patterns, peculiarities and meanings linked to the portrayal of money. This thesis does not encompass a comprehensive survey of money represented in all of cinema. Instead, the study is conducted in four groupings of films that are not necessarily thought of in connection with their images of money. Four chapters examine films from different contexts, periods, genres or trends in the cinema of various countries. The groupings are suggested partly by issues outside of money and partly by periods and kinds of money, and focus on case studies while simultaneously referring to a larger corpus. The first chapter examines the issues raised by the topic and surveys the existing literature. The second chapter undertakes an analysis of gold and gold mining in the context of the pioneering West in US films. The third chapter considers paper money and its meanings in neo-realist films. The thesis then proceeds to study films from the 1970s and 1980s. The fourth chapter concerns money in French films on high finance, and the last chapter looks at money as it appears in horror films. The thesis ends with a discussion of the recurrent patterns at work in the representation of money

Additive Manufacturing of Bio and Synthetic Polymers

Additive manufacturing technology offers the ability to produce personalized products with lower development costs, shorter lead times, less energy consumed during manufacturing and less material waste. It can be used to manufacture complex parts and enables manufacturers to reduce their inventory, make products on-demand, create smaller and localized manufacturing environments, and even reduce supply chains. Additive manufacturing (AM), also known as fabricating three-dimensional (3D) and four-dimensional (4D) components, refers to processes that allow for the direct fabrication of physical products from computer-aided design (CAD) models through the repetitious deposition of material layers. Compared with traditional manufacturing processes, AM allows the production of customized parts from bio- and synthetic polymers without the need for molds or machining typical for conventional formative and subtractive fabrication.In this Special Issue, we aimed to capture the cutting-edge state-of-the-art research pertaining to advancing the additive manufacturing of polymeric materials. The topic themes include advanced polymeric material development, processing parameter optimization, characterization techniques, structure–property relationships, process modelling, etc., specifically for AM

Evolution-In-Materio: Solving Computational Problems Using Materials

The motivation behind the research is to show that evolutionary algorithms can exploit properties of materials to solve various computational problems without requiring a detailed understanding of such properties. This approach is referred to as evolution-in-materio. In this research, it has been shown that using a purpose-built hardware platform called Mecobo, it is possible to evolve voltages and signals applied to physical materials to solve a number of computational problems. Here it has been demonstrated for the first time that the evolution-in-materio method can be applied to function optimisation, machine learning classification, frequency classification, even parity and bin packing problems. This evolution-in-materio method has also been applied here to discriminate tones and control robots. The physical material used in each of these experiments is a mixture of single-walled carbon nanotubes and a polymer. This is the first time that such material has been used to solve computational problems. The results of all of these experiments indicate that evolution-in-materio has promise and further investigations would be fruitful. Other than the solutions regarding these computational problems, this thesis has also devised and investigated suitable input-output mappings and input signals that allow various computational problems to be solved using the Mecobo platform and the experimental material

Balancing tissue homeostasis and inflammatory responses against Candida albicans infections: is it a matter of mast cells' immunological memory?

Mast cells (MC) are long lived immune cells widely distributed at mucosal surfaces among the first immune cell type that can get in contact with the external environment. This study aims to unravel the mechanisms of reciprocal influence between mucosal mast cells, the human commensal Candida albicans and microbial bioproducts. Stimulation of bone marrow-derived mast cells (BMMC) with live forms of C. albicans induced the release of TNF-\u3b1, IL-6, IL-13 and IL-4. Quite interestingly, BMMC were able to engulf C. albicans hyphae, rearranging their \u3b1-tubulin cytoskeleton accumulating LAMP1+ vesicles at the phagocytic synapse with the fungus. Infected MCs failed to promote macrophage chemotaxis but instead increased their crawling ability. On the other side, resting MCs inhibited macrophage phagocytosis of C. albicans in a contact-dependent manner. Several microbial ligands are known to induce immune memory on macrophages and natural killer cells. To determine whether this is true also for MCs and if their training could afford protection against fungal infections, BMMCs were stimulated for 24 hour with microbial ligands, washed and allowed to rest for 6 days and then restimulated with LPS or C. albicans. LPS-primed cells showed a decreased release of TNF-\u3b1 and IL-6 upon restimulation with LPS (a condition known as endotoxin tolerance) but an increased release of TNF-\u3b1 during fungal challenge. The impaired response during endotoxin tolerance relied on the impaired activation of the PI3K-AKT-p38 pathway, which led to a decreased NF-\u3baB activation and TNF-\u3b1 expression. On the other side, the training effect of LPS was mediated by the enhanced activation of NF-\u3baB and the sustained basal transcription of TNF-\u3b1. These results indicate that MCs are important gatekeeper of tissue homeostasis. Signals received from the microbiota can shape their immune memory, dampening the inflammation in response to bacterial LPS but affording protection during fungal infections

Evolutionary synthesis of analog networks

The significant increase in the available computational power that took place in recent decades has been accompanied by a growing interest in the application of the evolutionary approach to the synthesis of many kinds of systems and, in particular, to the synthesis of systems like analog electronic circuits, neural networks, and, more generally, autonomous systems, for which no satisfying systematic and general design methodology has been found to date. Despite some interesting results in the evolutionary synthesis of these kinds of systems, the endowment of an artificial evolutionary process with the potential for an appreciable increase of complexity of the systems thus generated appears still an open issue. In this thesis the problem of the evolutionary growth of complexity is addressed taking as starting point the insights contained in the published material reporting the unfinished work done in the late 1940s and early 1950s by John von Neumann on the theory of self-reproducing automata. The evolutionary complexity-growth conditions suggested in that work are complemented here with a series of auxiliary conditions inspired by what has been discovered since then relatively to the structure of biological systems, with a particular emphasis on the workings of genetic regulatory networks seen as the most elementary, full-fledged level of organization of existing living organisms. In this perspective, the first chapter is devoted to the formulation of the problem of the evolutionary growth of complexity, going from the description of von Neumann's complexity-growth conditions to the specification of a set of auxiliary complexity-growth conditions derived from the analysis of the operation of genetic regulatory networks. This leads to the definition of a particular structure for the kind of systems that will be evolved and to the specification of the genetic representation for them. A system with the required structure — for which the name analog network is suggested — corresponds to a collection of devices whose terminals are connected by links characterized by a scalar value of interaction strength. One of the specificities of the evolutionary system defined in this thesis is the way these values of interaction strength are determined. This is done by associating with each device terminal of the evolving analog network a sequence of characters extracted from the sequences that constitute the genome representing the network, and by defining a map from pairs of sequences of characters to values of interaction strength. Whereas the first chapter gives general prescriptions for the definition of an evolutionary system endowed with the desired complexity-growth potential, the second chapter is devoted to the specification of all the details of an actual implementation of those prescriptions. In this chapter the structure of the genome and of the corresponding genetic operators are defined. A technique for the genetic encoding of the devices constituting the analog network is described, along with a way to implement the map that specifies the interaction between the devices of the evolved system, and between them and the devices constituting the external environment of the evolved system. The proposed implementation of the interaction map is based on the local alignment of sequences of characters. It is shown how the parameters defining the local alignment can be chosen, and what strategies can be adopted to prevent the proliferation of unwanted interactions. The third chapter is devoted to the application of the evolutionary system defined in the second chapter to problems aimed at assessing the suitability in an evolutionary context of the local alignment technique and to problems aimed at assessing the evolutionary potential of the complete evolutionary system when applied to the synthesis of analog networks. Finally, the fourth chapter briefly considers some further questions that are relevant to the proposed approach but could not be addressed in the context of this thesis. A series of appendixes is devoted to some complementary issues: the definition of a measure of diversity for an evolutionary population employing the genetic description introduced in this thesis; the choice of the quantizer for the values of interaction strength between the devices constituting the evolved analog network; the modifications required to use the analog electronic circuit simulator SPICE as a simulation engine for an evolutionary or an optimization process

The project TEMPUS — ECOMMIS («double-level training programs of e-commerce developing the information society in Russia, Ukraine and Israel») was launched in October 2011, and belongs to a class of joint projects to develop new courses and courses for bachelor’s and master’s degrees. The project consortium involves 12 universities from Germany, the Netherlands, Lithuania, Israel, Russia and Ukraine. The main objective of the project is to develop and implement new academic courses and areas of study, taking into account the current status and trends of economic development and the specific requirements of the labor market on the basis of cooperation between universities in different countries. The main feature and complexity of the project academic content of is that e-commerce as an academic concept is absolute new and it appeared just only in the last decade. It is a new interdisciplinary field of knowledge, which is located at the intersection of economics and computer science and it is not covered by the classical training courses in economics and computer science technology. The aspects of national and international law in connection with the growth of international trade, economic cooperation and the development of new Internet based technologies should be taken into account. For the project’s period of three years on the basis of international cooperation the following results were obtained: 11 Preface 1) The analysis and modernization of existing curricula in the field of e-commerce were carried out; 2) new training modules with the introduction of the European creditmodular system of accumulation and transfer transcripts units ( ECTS ) were developed; new modules and courses: e-commerce, electronic payment systems; Internet trading in the financial markets and the stockmarket systems; Information systems for financial analysis and investment; Information systems for business process modeling; corporate information systems and portals; Customer-oriented systems; Internet Marketing; electronic systems for document management; legal aspects of e-commerce; advanced course security for e-commerce were introduced; 3) two international online games to enhance practical skills in the field with online marketing and online trading were developed and conducted among university students; 4) skills training courses e-commerce for various social groups (students, housewives, pensioners, unemployed) were developed and tested; 5) business offices, e-commerce were established to strengthen cooperation between the universities in the labor market and to create the conditions of commercialization of the project results after the end of financial support from the TEMPUS Program. 6) textbooks on the topic of the project were developed and published. In May — July 2013. 62 teachers targeted universities in Israel, Russia and Ukraine received intensive training in the field of e-commerce in three European universities: FONTYS (NL), TU Berlin (DE), VGTU ( LT ). From October 2013 in target universities of Israel, Russia and Ukraine students’ training began on the courses developed in the framework of the new training courses and modules with using computer classes, equipped in accordance with the project plan with new hardware and software tools. The final stage of the project was intended to develop a five-year detailed plan for sustainable development of the results. Such plan that includes coordinated action to disseminate best practices, development of new joint courses for graduate and post-graduate students, scientificmethodical conferences, joint publications will support the further dynamics of the activities involved universities. Joint work on the implementation of the project ECOMMIS led to the emergence of sustainable professional relationships between organizations in the consortium as the training of new qualified professionals, as well as in the field of scientific and methodological developments. This is confirmed by the present collective monograph E-commerc
