Intercomparison of instruments for measuring leaf area index over rice

2015

Leaf area index (LAI) is a key biophysical parameter used to determine foliage cover and crop growth in environmental studies in order to assess crop yield. LAI estimates can be classified as direct or indirect methods. Direct methods are destructive, time consuming, and difficult to apply over large fields. Indirect methods are non-destructive and cost-effective due to its portability, accuracy and repeatability. In this study, we compare indirect LAI estimates acquired from two classical instruments such as LAI-2000 and digital cameras for hemispherical photography, with LAI estimates acquired with a smart app (PocketLAI) installed on a mobile smartphone. In this work it is shown that LAI…

A Kalman filter single point positioning for maritime applications using a smartphone

2020

Different positioning techniques have been largely adopted for maritime applications that require high accuracy kinematic positioning. The main objective of the paper is the performance assessment of a Single Point Positioning algorithm (SPP), with a Kalman filter (KF) estimator, adapted for maritime applications. The KF has been chosen as estimation technique due to the ability to consider both the state vector dynamic and the measurements. Particularly, in order to compute an accurate vertical component of the position, suitable for maritime applications, the KF settings have been modified by tuning the covariance matrix of the process noise. The algorithm is developed in Matlab environme…

Musica y significado

2000

This article discusses both classical theories of musical meaning, the imitative one and the expressive one, wich share a referentialist idea of meaning. It also criticizes the sintacticist choice of formalism as well. Opposite to all these views, the paper outlines an explanation of musical meaning inspired in the later linguistic philosophy o Wittgenstein. El artículo discute las clásicas teorías imitativa y expresiva del significado de la música, que comparten una noción referencialista del significado, y critica asimismo la alternativa sintacticista del formalismo. Frente a estas posiciones, propone una explicación del significado de la música inspirada en la filosofía del lenguaje del …

The Myths of and Solutions for Android OS Controlled and Secure Environment

2015

<p class="R-AbstractKeywords"><span lang="EN-US">Android is the most popular mobile operating system nowadays both for smartphones and tablets. This fact creates many not fully recognized risks. Often even advanced users naive think that using antivirus software, firewall, encryption, updates, as well as avoiding potentially risky sites and applications are enough for security. This list is not full, but nevertheless each its item in most cases only conceals an illusion of reaching the security. Authors have summarized and pointed out several actual Android security issues and have proposed a number of possible solutions.</span></p><p class="R-AbstractKeywords"&gt…

Rethinking the Westphalian Order During WW I : Max Weber on the Timeliness of the European Polity

2017

The publication of the Max-Weber-Gesamtausgabe volumes, including his letters and a recent study of Hinnerk Bruhns, have revised the canonical view on Weber as a German nationalist. With a conceptual and rhetorical analysis of his essays Deutschland unter europäischen Weltmächten (1916) and Zum Thema Kriegsschuld (early 1919), I offer an alternative view on Weber’s relationship to European politics. He defended the ‘Westphalian’ system of balance between great powers, to which he wanted after the end of the War to incorporate Woodrow Wilson’s plans for a new League. Weber was a critic of German wartime policy, maintained his Anglophile sympathies, and saw in tsarist Russia the main threat b…

Valori perduti e perduta libertà. Croce e il dibattito tedesco sulla relatività dei valori

2017

The relativism of values (Werterelativismus) is a problem very central for the historicism debate, which concerned historians and phi- losophers at the beginning of the twentieth century. The historization of all knowledge and all values leads to their historical devaluation. How can values still be formulated and maintained in face of this relativization? This was the question of theorists such as Otto Hintze, Friedrich Meinecke, Max Weber and Ernst Troeltsch, as well as of the philosopher Benedetto Croce in times of emerging Fascism, that was regarded as a political and moral threat. As representatives of an intellectual and social liberalism, these academics developed their own strategie…

A Study on the Usage of Smartphone Apps in Fire Scenarios - Comparison between GDACSmobile and SmartRescue Apps

2015

In this paper, we present a thorough overview of the two recently developed applications in the field of emergency management. The applications titled GDACSmobile and SmartRescue are using mobile app and smartphone sensors as the main functionality respectively. Furthermore, we argue the differences and similarities of both applications and highlight their strengths and weaknesses. Finally, a critical scenario for fire emergency in a music festival is designed and the applicability of the features of each application in supporting the emergency management procedure is discussed. It is also argued how the aforementioned applications can support each other during emergencies and what the pote…

On the Usability of Smartphone Apps in Emergencies

2015

It is very critical that the disaster management smartphone app users be able to interact efficiently and effectively with the app during an emergen-cy. An overview of the challenges face for designing mobile HCI in emergency management tools is presented in this paper. Then, two recently developed emergency management tools, titled GDACSmobile and SmartRescue, are studied from usability and HCI challenges point of view. These two tools use mobile app and smartphone sensors as the main functionality respectively. Both have a smartphone app and a web-based app with different UIs for their different user groups. Furthermore, the functionality of these apps in the format of a designed scenario…

[Cu(P^P)(N^N)][PF6] compounds with bis(phosphane) and 6-alkoxy, 6-alkylthio, 6-phenyloxy and 6-phenylthio-substituted 2,2'-bipyridine ligands for lig…

2018

We report a series of [Cu(P^P)(N^N)][PF6] complexes with P^P = bis(2-(diphenylphosphino)phenyl)ether (POP) or 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (xantphos) and N^N = 6-methoxy-2,2′-bipyridine (MeObpy), 6-ethoxy-2,2′-bipyridine (EtObpy), 6-phenyloxy-2,2′-bipyridine (PhObpy), 6-methylthio-2,2′-bipyridine (MeSbpy), 6-ethylthio-2,2′-bipyridine (EtSbpy) and 6-phenylthio-2,2′-bipyridine (PhSbpy). The single crystal structures of all twelve compounds have been determined and confirm chelating modes for each N^N and P^P ligand, and a distorted tetrahedral geometry for copper(I). For the xantphos-containing complexes, the asymmetrical bpy ligand is arranged with the 6-substituent lying …
