Photovoltaic Plant

Photovoltaic (PV) plant monitoring and maintenance has become an often critical activity: the high efficiency requirements of the new European policy have often been in contrast with the many low-quality plants installed in several countries over the past few years. In actual industrial practices, heterogeneous information is produced, and they are often managed in a fragmented way. Several software tools have been developed for obtaining reliable and valuable information from the PV plant’s raw data. With the aim of gathering and managing all these data in a more complex and integrated manner, an information managing system is proposed in this work—it is composed of a structured database, called the Photovoltaic Indexed Database, and a user interface, called the Digital Map, that allows for easy access and completion of the information present in the database. This information managment system and PV plant digitalization process is able to analyze and properly index the IR in the database, as well as the visual images obtained in photovoltaic plant monitoring.

The production of multimedia content has grown overwhelmingly in recent years due to decreasing hardware costs, inexpensive storage and ubiquitous high-bandwidth networks. In addition, the introduction of digital video is completely changing the landscape of the entire video value chain. The easy access and increased availability of multimedia is posing new challenges to manage the data. Image and video archives in broadcast studios, corporate archives of multimedia collaborative sessions, video conferencing sessions and educational videos all require tools for quickly locating video segments of desired content with transparent access. The market for such tools, known as media asset-management tools, has been growing rapidly. In this chapter we will discuss the general architecture and the tools for media content management. We will survey some of the techniques that employ methods of data management beyond traditional databases. We will discuss existing research prototypes and some commercially available systems. These systems enable applications that facilitate effective access, interaction, browsing and display of complex and inhomogeneous information consisting of images, video and audio.

Magnetic Skyrmions

AbstractMagnetic skyrmions are topologically non-trivial, swirling magnetization textures that form lattices in helimagnetic materials. These magnetic nanoparticles show promise as high efficiency next-generation information carriers, with dynamics that are governed by their topology. Among the many unusual properties of skyrmions is the tendency of their direction of motion to deviate from that of a driving force; the angle by which they diverge is a materials constant, known as the skyrmion Hall angle. In magnetic multilayer systems, where skyrmions often appear individually, not arranging themselves in a lattice, this deflection angle can be easily measured by tracing the real space motion of individual skyrmions. Here we describe a reciprocal space technique which can be used to determine the skyrmion Hall angle in the skyrmion lattice state, leveraging the properties of the skyrmion lattice under a shear drive. We demonstrate this procedure to yield a quantitative measurement of the skyrmion Hall angle in the room-temperature skyrmion system FeGe, shearing the skyrmion lattice with the magnetic field gradient generated by a single turn Oersted wire.

This article considers the history of donation management tools on the livestreaming platform Twitch. In particular, it details the technical and economic contexts that led to the development of Twitch Bits, a first-party donation management service introduced in 2016. Two contributions to research on the platformization of cultural production are made. One, this article expands the empirical record regarding Twitch by chronicling the role of viewer donations in livestreaming since 2010, as well as the many tools that have facilitated this practice. It is argued that this history traces the complex and co-productive interactions between Twitch as a sociotechnical architecture and a political economy. Two, by considering how the first-party donation tool Twitch Bits has gradually challenged the dominance of the third-party tools that preceded it, this article theorizes the notion of platform capture, a critical rereading of platform envelopment, a popular concept in business studies. Ultimately, it is argued that platform capture demonstrates how platform owners leverage power asymmetries over dependents to aid in their platform’s technical evolution.

AbstractThe most useful and practical strategy available for reducing variability of net farm income is ascertained. Of the many risk management tools presently available, five of the most commonly used are simultaneously incorporated in an empirically tested model. Quadratic programming provides the basis for decisionmaking in risk management wherein expected utility is assumed to be a function of the mean and variance of net income. Results demonstrate that farmers can reduce production and price risks when a combination strategy including a diversified crop production plan and participation in the futures market and the Federal Crop Insurance Program (FCIP) is implemented.

Considerable Depth

Any defense of universal norms involves drawing distinctions among the many things people actually desire. If it is to have any content at all, it will say that some objects of desire are more central than others for political purposes, more indispensable to a human being's quality of life. Any wise such approach will go even further, holding that some existing preferences are actually bad bases for social policy. The list of Central Human Capabilities that forms the core of my political project contains many functions that many people over the ages have preferred not to grant to women, either not at all, or not on a basis of equality. To insist on their centrality is thus to go against preferences that have considerable depth and breadth in traditions of male power. Moreover, the list contains many items that women over the ages have not wanted for themselves, and some that even today many women do not pursue – so in putting the list at the center of a normative political project aimed at providing the philosophical underpinning for basic political principles, we are going against not just other people's preferences about women, but, more controversially, against many preferences (or so it seems) of women about themselves and their lives. To some extent, my approach, like Sen's, avoids these problems of paternalism by insisting that the political goal is capability, not actual functioning, and by dwelling on the central importance of choice as a good. But the notion of choice and practical reason used in the list is a normative notion, emphasizing the critical activity of reason in a way that does not reflect the actual use of reason in many lives.
