Nonlinear phase noise (NLPN) is the most common impairment that degrades the performance of radio-over-fiber networks. The effect of NLPN in the constellation diagram consists of a shape distortion of symbols that increases the symbol error rate due to symbol overlapping when using a conventional demodulation grid. Symbol shape characterization was obtained experimentally at a moderate baud rat…
ISTAT census layers, realized by ISTAT since 1991, are in update; this kind of digital cartography divides the entire national territory in very small enumeration areas to which are linked all the variables gathered during the census surveys. This layer, thanks to the several pieces of information related to each enumeration area, has a huge value for the statistical description of the Italian …
The aim of this paper is to verify that in economies prior to the 18th century and from the Middle Ages onwards, there was a significant increase in the application of knowledge in the goods produced and a development of both technological and organizational innovation, i.e. "useful knowledge". It is also a question of verifying the effect of cultures, institutions and power structures on the g…
There have been outsourcing and insourcing trends for decades. Most often benefits and costs of outsourcing are compared from the purely financial side. However, risks are those that eventually determine whether a particular product/service/asset should be outsourced or not. The aim of this chapter is to fill in the gap in the literature by analysing risk-reward or benefit-cost ratio in outsour…
In recent years, several studies have focused on the interpretation and possible function of the so-called Hittite landscape monuments. For many of these monuments, a connection with the sphere of religion and cultic celebration has been suggested, especially taking into account the possible sanctity of their location, often connected to mountains, rocky outcrops, and water. The landscape monum…
In the 1960s and 1970s this formalist version seen in the previous chapter began to show signs of fatigue. Some critics and art historians began to show interest in the personages on stage in Les Demoiselles. Early on John Nash linked the damsel squatting at lower right of the canvas with the myth of Medusa. Leo Steinberg immediately formulated a series of questions that constituted a direct at…
In Italy, the National Institute for the Evaluation of the Education and Training System (INVALSI) every year administers standardized tests via computer-based testing (CBT) to students attending grades 8, 10, and 13. The CBT mode allows to collect data not only on the students’ response accuracy (RA) based on item responses, but also on their response times (RT). By using these data, it is n…
The Italian Institute for Environmental Protection and Research (ISPRA) has developed the Geodatabase “Linea di Costa”. that allows to perform spatial analysis on the recorded geometrical elements, and to provide a periodic update on the evolution of the coastline. The main objective of this work is to highlight the potential of a continuously updated geodatabase over time in monitoring and…
Photosynthetic eukaryotic cells arose more than a billion years ago through the engulfment of a cyanobacterium that was then converted into a chloroplast, enabling plants to perform photosynthesis. Since this event, chloroplast DNA has been massively transferred to the nucleus, sometimes leading to the creation of novel genes, exons, and regulatory elements. In addition to these evolutionary no…
Planning and designing lifelong teaching-learning processes requires well-educated professionals in adult and continuing education. Against the background of changing social structures, they must be able to act confidently in interdisciplinary, cooperative and unpredictable interaction situations. This requires the development of professionalism in adult education with respect to the following …
