The reconstruction of the chronology of historical buildings is a tricky issue, as usually there are not historical documents that allow the assessment of construction phases, and some materials are hardly reliable for the use of dating techniques (e.g., stone). However, in the last two decades, important advances on the use of absolute dating methods on building materials have increased the po...

Current approaches in Digital .Humanities tend to ignore a central aspect of any hermeneutic introspection: the intrinsic vagueness of analyzed texts. Especially when dealing with historical documents neglecting vagueness has important implications on the interpretation of the results. In this paper we present current limitation of annotation approaches and describe a current methodology for an...

This paper focuses on a set of structured document applications that we have denoted databases of historical documents. The information into these documents is closely related to the time in which they are created while being still of great usefulness in the future. The main contribution of this paper is the formulation of a group of operators and predicates that express retrieval conditions ov...

How does the magnitude of the output response to a change in government spending vary over the business cycle? What are the welfare effects of fiscal shocks? This paper studies the state-dependence of the output and welfare effects of shocks to government purchases in a DSGE model with a number of real and nominal frictions and a rich fiscal financing structure. Both the output multiplier (the ...

The development of IC industry in Taiwan began with a technology transfer from the U.S. based RCA Company, which was conducted by Industrial Technology Research Institute (ITRI). ITRI’s Technology Transfer Team (TTT) members were first incubated in the National Laboratories at ITRI, and then dispatched to spin-off companies in the Hsinchu Science and Industrial Park (HSIP). Many of these TTT me...

The Qing Imperial Court documents are a major source of primary research material for studying the Qing era China since they provide the most direct and first-hand details of how national affairs were handled. However, the way Qing archived these documents has made it cumbersome to collect documents covering the same event and rebuild their original contexts. In this paper, we describe some inf...

Recently, several striking advances have taken place regarding the discrete logarithm problem (DLP) in finite fields of small characteristic, despite progress having remained essentially static for nearly thirty years, with the best known algorithms being of subexponential complexity. In this expository article we describe the key insights and constructions which culminated in two independent q...

The nature of our star, the Sun, is dominated by its complex and variable magnetic fields. It is the purpose of this paper to review the fundamental nature of our magnetic Sun by outlining the most basic principles behind the way the Sun works and how its fields are generated, and to examine not only the historical observations of our magnetic star, but, in particular, to study the wonderful ob...

This paper studies and measures the output of sustainable (eco) innovation in the OECD area. Results are based on patent records and their use as indicators of innovation output. Two points have to be noted: First, It is of particular importance, when examining the innovation output of a broad area, which comprises of many and different countries, to identify main trends, highlight major innova...
