This chapter deals with data production within the paradox of big-no data in urban logistics. More precisely, the chapter aims to make an overview on data production in urban logistics and present the main issues, as well as a framework, to overcome that paradox. First, the big-no data paradox is defined and motivated. Second, the question of demand and route estimation in urban logistics is examined more in-depth via an overview of current data production methods and techniques used to estimate demand and transport flows. Third, a framework to produce unified databases filling those data lacks is introduced as well as an analysis on how the different data production techniques can be used to overcome that paradox. Finally, research directions regarding urban goods transport data production are provided.

Usage Area

Lightweight materials were needed in many different areas, especially in order to reduce the required energy in areas such as automotive and aerospace industries. Metallic foams attract attention in lightweight material applications due to their unique properties. The pores in its structure provide advantages in many applications, both structural and functional by promising both ultra-lightweight construction, energy absorption, and damping insulation. Production techniques of metallic foams can generally be classified as liquid, solid, gas, and ionic state production according to the physical state of the metal at the beginning of the process. The production technique should be chosen according to the usage area and desired properties of the metallic foam and the suitability in terms of cost and sustainability of production. For this reason, the details of the production techniques should be known and the products that can be obtained and their properties should be understood. In this respect, this chapter emphasizes the production methods from past to present.

Kinetics Of

Quantitative expressions of the kinetics of digestion are needed to estimate more precisely the quantity and composition of nutrients digested from feeds and their subsequent efficiency of utilization by the animal (Mertens, 1993). Degradation kinetic parameters are estimated by fitting appropriate models to data resulting from the measurement of either the undigested residue or the fermentation end-products after exposure of the feed to digestion. Kinetic data can be collected using either in vitro or in situ procedures. The in situ porous synthetic fibre bag technique has been extensively used to describe the kinetics of feeds degradation in the rumen. Several in vitro gas production methods have been developed to assess fermentation kinetics. The aim of this work was to study the relationship between rumen degradation parameters of forages determined either by the in situ procedure or by the gas production technique and to evaluate the potential of gas production measurements to assess the extent of dry matter degradation in the rumen.

Expansion Period

The opening decades of the twentieth century witnessed a profound transformation in the history of modern sound media, with workers in US film, radio, and record industries developing pioneering production methods and performance styles tailored to emerging technologies of electric sound reproduction that directly shaped dominant forms and experiences of modern sound culture. Focusing on broadcasting’s initial expansion period during the 1920s, Making Radio explores the forms of creative labor pursued for the medium before the better-known network era of the 1930s and 1940s, assessing their role in shaping radio’s own identity and identifying affinities with parallel practices pursued for conversion-era film and phonography. Tracing programming forms adopted by early radio writers and programmers, production techniques developed by studio engineers, and performance styles cultivated by on-air talent, it shows how radio workers negotiated a series of broader industrial and cultural pressures to establish best practices for their medium. In the process, it argues, these sound workers shaped not only the future of broadcasting, but also contributed to much broader shifts in popular forms of music, drama, and public oratory, ushering in a new era of electric sound entertainment.

Ancient Times

Written manuscripts and literary treatises are among the most important documents of knowledge on traditional color production techniques related to painting, and as they have survived thanks to desirable maintenance and preservation from the ancient times to the present time, they can be good sources for identifying and extracting traditional color production methods related to paining. Especially, the illustrated books simultaneously with their writing are an evidence of the contents presented in those manuscripts and treatises. Therefore, by an aim to identify and revive traditional color production techniques, the present descriptive-analytic research examines some of the available handwritten manuscripts and literary treatises. Then, with emphasis placed on the knowledge acquired and the modern facilities, some of the colors are made. The present study was performed by raising the major question that what ancient literary books are the sources of production colors used in Persian painting, and what were the nature of color production techniques and traditional color characteristics in the past. Thus, the study population includes Golestan Honar, Qanun al-Sovar, Majmoueh al-Sanaye’ and 14 other treatises relevant to this issue, and the data collection was performed in a library- and experimental-based manner. The result of this study was the extraction, preparation and remaking of seven main mineral colors in Persian painting.

The nascent field of data science and the expansion of the higher education sector share surprising affinities. The emergence of the “entrepreneurial university” has brought increasing differentiation of the work roles of academics in addition to increased mobility and, for some, precarity. At the same time, researchers are dealing with unprecedented amounts of data. The present article describes how policies and infrastructures implemented to support researchers with data curation tasks might be repurposed by research administrators to tackle problems of academic mobility rooted in increasing precarity of non-tenured research staff. Findings suggest that the organizational benefit of research data management (RDM) is not increased efficiency or reusability of research, but rather increased control over data left behind by non-tenured staff. Recent interest in data mobility needs to be understood by reference to increased researcher mobility. While the view of data as context-independent evidence has been challenged by reference to the investments necessary to mobilize data as evidence in the first place, the material presented here suggests that RDM is repurposed by universities as a strategy to manage, not data, but rather increasing rates of staff turnover. The mobility of data producers and the immobility of data are frequently in tension. Handing over data is problematic irrespective of domain, data type, and funding source. The term “high-throughput university” is introduced in opposition to “high-throughput” data production techniques to suggest that findability and reusability of data need to be recontextualized with reference to increased academic mobility.
