Good and useless FDI: The growth effects of greenfield investment and mergers and acquisitions
2017
We explore the effect of foreign direct investment (FDI) on economic growth, distinguishing between mergers and acquisitions (M&As) and “greenfield” investment. A simple model underlines that, unlike greenfield investment, M&As partly represent a rent accruing to previous owners, and do not necessarily contribute to expanding the host country's capital stock. Greenfield FDI should therefore have a stronger impact on growth than M&A sales. This hypothesis is supported by our empirical results that are based on a panel of up to 127 industrialized, emerging, and developing countries over 1990 to 2010.
Earnings management of target firms and deal premiums: The role of industry relatedness
2022
This paper contributes to the merger and acquisitions (M&A) literature by providing evidence for the role of industry relatedness in the association between target firms' earnings management (EM) before the deal and the premium offered by the acquirer. We argue that familiarity with the industry's policies and practices is a crucial factor that helps acquirers to see through targets' EM. Our evidence supports this prediction in relation to accounting manipulation as we observe that the income increasing accrual manipulation of the target results in significantly higher premiums offered by acquirers in interindustry deals, which is not the case when targets and acquirers belong to the same i…
Building Information Modeling (BIM) Enabled Facilities Management Using Hadoop Architecture
2017
International audience; Protecting the safety of occupants and the environment is a core value within Facilities Management. Data acquisition systems such as wireless sensor networks can help to monitor facilities to reduce hazards such as fire, water flooding and burglaries. Building Information Modeling (BIM) is a revolutionary development that is reshaping the Architecture Engineering and Construction (AEC) industry. BIM is both a process and a technology, offers wide solutions for facilities management. In order to monitor and manage facilities data in a BIM based simulated environment, this work reports upon a development of a system that uses BIM software and a wireless sensor technol…
A microcomputer system for controlling classical conditioning experiments
1994
A microcomputer-based laboratory system for controlling stimulus presentations and data acquisition in classical conditioning experiments is described. The system comprises an Intel 386/486-based microcomputer and a commercially obtained low-cost counter/timer board with input/output lines for stimulus timing and external device control. A simple, yet versatile custom-designed structured programming language is provided for performing an unlimited number of stimulus configurations and their sequences. In electrophysiological studies, the system can be flexibly connected to computer-controlled signal conditioning systems for the amplification and filtering of multiunit and evoked field poten…
Breedbot: An Edutainment Robotics System to Link Digital and Real World
2007
The paper describes Breedbot an edutainment software and hardware system that could be used to evolve autonomous agents in digital (software) world and to transfer the evolved minds in physical agents (robots). The system is based on a wide variety of Artificial Life techniques (Artificial Neural Networks, Genetic Algorithms, User Guided Evolutionary Design and Evolutionary Robotics). An user without any computer programming skill can determine the robot behaviour. Breedbot was used as a didactic tool in teaching Evolutionary Biology and as a futuristic toy by several Science Centers. The digital side of Breedbot is downloadable from www.isl.unina.it/breedbot.
Impact of Storage Acquisition Intervals on the Cost-Efficiency of the Private vs. Public Storage
2012
The volume of worldwide digital content has increased nine-fold within the last five years, and this immense growth is predicted to continue in foreseeable future reaching 8ZB already by 2015. Traditionally, in order to cope with the growing demand for storage capacity, organizations proactively built and managed their private storage facilities. Recently, with the proliferation of public cloud infrastructure offerings, many organizations, instead, welcomed the alternative of outsourcing their storage needs to the providers of public cloud storage services. The comparative cost-efficiency of these two alternatives depends on a number of factors, among which are e.g. the prices of the public…
Pico: A data acquisition program for picosecond laser spectroscopy
1992
Abstract A data acquisition and control program for picosecond pump and probe experiments has been developed. The program PICO is written in C-programming language for maximum efficiency. The software which runs on an IBM PC compatible microcomputer controls a stepper motor driven optical delay, and at the same time collects data from a digital lock-in amplifier. PICO can be used to control any experiment utilizing two-beam pump probe technique. The modular structure of the software allows for easy implementation with different hardware configurations. The program includes: measurement option, manual control of the delay line using a joystick and functions for file retrieval and editing. Ad…
A damage identification procedure based on Hilbert transform: Experimental validation
2010
SUMMARY This paper aims at validating the feasibility of an identification procedure, based on the use of the Hilbert transform, by means of experimental tests for shear-type multi-degree-of-freedom systems. Particularly, a three-degree-of-freedom frame will be studied either numerically or experimentally by means of a laboratory scale model built at the laboratory of the Structural, Aerospace and Geotechnical Engineering Department (DISAG) of University of Palermo. Several damage scenarios have been considered to prove the effectiveness of the procedure. Moreover, the experimental tests have been conducted by considering two different input loads: pulse forces, simulated by means of an ins…
Conceptual Ontological Object Knowledge Base and Language
2008
This paper deals with AI in aspect of knowledge acquisition and ontology base structure. The core of the system was designed in an object model to optimize it for further processing. Direct concept linking was used to assure fast semantic network processing. Predefined attributes used in the core minimize the number of basic connections within the ontology and help in inference. The system is assumed to generate questions and to specify the knowledge. The AI system defined in this way opens a possibility for better understanding of such basic human mind mechanisms as learning or analyzing.
Hardware and software designing of USB based plug n play data acquisition device with C# and LabView compatibility
2015
As interdisciplinary sciences getting popular with every passing day, the need of electronic devices interfacing with a PC is also increasing. Very useful products (Arduino, RasberryPi, etc) made their way in commercial market to cater such needs however they require programming skills, specific IDE's (integrated development environments) and lack compatibility with useful tools such as NI (National Instrument) LabView[1] and C#. Since these two (C# and LabView) are supposed to be widely used for their user friendliness, but unfortunately are not prioritised as a development option due to lack of supporting hardware which is either too expensive, rare or too complex. Hence in this research …
