Drones - New technologies for geophysics?
2015
Drones, also referred as Unmanned Aircraft Systems (UAS), Unmanned Aerial Vehicles (UAV) or Remotely Piloted Aircraft (RPA), are aircraft without pilot on board. USA is today the leading country in the field of UAS but recently, seven European countries have pledged to launch joint programs for drones, with the aim of producing the next generation of UAS before 2020. According to some studies on the potential market of UAS in Europe, the geoscience sector is definitely one of the most promising. In this paper, we bring a short description and classification of drones, according to their sized and shaped, with particular attention to the advantages and drawbacks of each type in reference to …
A new preprocessing and control board for the phase 2 electronics of AGATA experiment
2016
The electronics of AGATA HPGe segmented gamma ray detector faces a new challenge in the search of a bigger integration and cost reduction for the phase 2 of the experiment going beyond 45 crystals. This opportunity can be used to introduce a new architecture based on commercial standards while keeping backward compatibility with current electronics. In this sense, new FPGA devices and fast Ethernet links can be used to ease the preprocessing and control task and allowing for processor farms to distribute the processing load. At the same time, modularity should be a key feature of the design in the aim to make it upgradable in time and technology. This paper presents the design of a new prep…
Determinants of Chairman Compensation
2011
This study examines determinants of chairman compensation in a supervisory board setting and, specifically, the relationship between chairman and CEO compensation. Using a sample of publicly listed firms in Sweden, the study indicates that chairman compensation – despite its fixed nature – is reflective of firm performance via a positive relationship to CEO compensation. As CEO compensation is set before chairman compensation, we argue that the chairman may be inclined to conspire with the CEO in earnings management efforts at the expense of monitoring on behalf of investors. Supporting our argument, we find evidence that the gap between chairman and CEO compensation is less at firms where …
Is Board Gender Diversity a Driver of CEO Compensation?: Examining the Leadership Style of Institutional Women Directors
2017
In this investigation, we aim at examining the influence of institutional female directors on CEO compensation. Specifically, we investigate the impact of institutional female directors as a whole, differentiating by whether female directors have business ties with the firms’ boards on which they sit (pressure-sensitive female directors) or do not have business links (pressure-resistant female directors). We hypothesize that there is a nonlinear association, specifically quadratic, between institutional, pressureresistant and pressure-sensitive female directors on boards, and CEO compensation. Our findings show that CEO compensation decreases with low levels of institutional female director…
Governance, board diversity and firm value
2010
This paper investigates the relations between firm on board diversity and firm value on a sample of Italian Publicly listed firm. Specifically, we look at the composition of boards (as defined board size, Majority of independent directors, leadership structure) and at his diversity (defined as the percentage of women and directors of other, average age of the board, other board’s member appointment). We provide evidence that board diversity positively affect performance.
Robotized semiautomatic motorcycle transmission development. Electronic and software design
2017
In this paper, we propose an electrical design (implemented on a PCB board) and an accompanying software design for controlling the automatic gear change. The designs complement the mechanical solutions developed in Part 1. The paper also analyses the issues encountered during the intermediate steps of the development of the electronic module, which is expected to be small and adaptable enough to be installed on a motorcycle without changing its ergonomics. The control software runs on the Arduino Nano board and is built as a state machine with one idle state, five active states that cover different stages of the gear change and one error state for preventing malfunctions in case of an unex…
The charter of foreigners merchant ships in the expulsion of the Andalusia Moriscos
2009
El embarque de moriscos a bordo de navíos mercantes de origen extranjero constituye una faceta interesante en el estudio del proceso de expulsión andaluz. Debido a la escasa participación de las escuadras reales y la necesidad de llegar a acuerdos concretos con los que suministrar embarcaciones para el transporte de los moriscos, la Corona y sus representantes se verían obligados a llegar a diferentes compromisos con los cónsules de las naciones de extranjeros, y algunos mercaderes particulares, para garantizar unos traslados que, de otra manera, se hubieran retrasado en exceso complicando toda la operación. De este modo y con el paso de las semanas, acabaría por evidenciarse el peso especí…
A New Systematic Series of Foil Sections with Parallel Sides
2020
Parallel-sided foil sections are used for centerboards and rudders in sailing dinghy classes and also for struts placed in a fluid flow. The objective of this work is to create a systematic series of parallel-sided sections to be used under different conditions, with an emphasis on the sailing dinghies 470, 420 and Optimist. The loss, and surprisingly the gain, in performance relative to 4-digit NACA sections are also investigated. A 2D Reynolds-averaged Navier&ndash
On the Internationalization of Corporate Boards
2013
Despite the global reach of their commercial activities, many multinational firms have proved slow in internationalizing their boards of directors. Based on a panel study of the internationalization of the boards of 347 non-financial firms from the Nordic countries, we find a higher fraction of international board membership in firms with more foreign sales, in firms with more foreign ownership and in firms whose shares are traded on foreign (mostly European) stock exchanges. Moreover, we find international directors and national directors with international experience complementary. The first-mentioned group is found to serve a monitoring role, related to financial internationalization of …
A High-Efficiency, Low-Cost Solution for On-Board Power Converters
2012
Wide-input, low-voltage, and high-current applications are addressed. A single-ended isolated topology which improves the power efficiency, reduces both switching and conduction losses, and heavily lowers the system cost is presented. During each switching cycle, the transformer core reset is provided. The traditional tradeoff between the maximum allowable duty-cycle and the reset voltage is avoided and the off-voltage of active switches is clamped to the input voltage. Therefore, the system cost is heavily reduced and the converter is well suited for wide-input applications. Zero-voltage switching is achieved for active switches, and the power efficiency is greatly improved. In the output …
