Performance maps for an air-cooled air conditioning system as a preliminary instrument for the diagnosis of evaporator fouling
2019
Abstract During the past few decades, there has been increased interest in the development of automated approaches for detecting and diagnosing faults in air conditioning systems. Among them, thermoeconomic diagnosis is a technique which involves the use of exergy analysis. As a first step towards improving its performance, this work is focused on the thermodynamic and exergy analysis of a direct expansion air conditioning system used in small commercial building applications. The analysis was carried out by means of experimental activities on a 17.5 kW rooftop unit installed at the Herrick Laboratories, Purdue University, Indiana (USA). The system under investigation was equipped with a va…
Advanced energetics of a Multiple-Effects-Evaporation (MEE) desalination plant. Part II: Potential of the cost formation process and prospects for en…
2010
This paper represents the 2nd part of a paper in two parts. In part I a 2nd Principle analysis of a Multiple- Effects-Evaporation (MEE) process has been proposed. In this Part II perspectives for process improvement will be investigated, along two distinct research lines: the thermoeconomics-aided optimization of a new system and the increase of thermal efficiency for existing systems by a pinch-based plant retrofit. As concerns the first research line, a detailed productive structure for the plant stage (i.e. effect) examined in Part I is presented; the cost formation structure is then used to improve a simplified optimization process, revealing capable to properly reflect the interactions…
Corporate Social Responsibility and Sustainability of Local Community: A Case Study of the Transnational Project in China-Pakistan Economic Corridor
2019
While achieving great benefits, the Belt and Road Initiative (BRI) has triggered potential problems between the transnational projects and local communities in the participant countries. However, there is still a knowledge gap on how corporate social responsibility (CSR) is adopted, and how CSR affects the local community. Based on a context of China-Pakistan Economic Corridor (CPEC), this research exploits a combination of qualitative and quantitative methods to fill the gap. It finds that the CSR activities in the CPEC project are initiated by the long-term CSR initiative. Organized by the professional CSR foundation in an autonomous environment, the panoramic CSR activities are governed …
Why corporates syndicate their investments with a specific partner? An explorative analysis of corporate venture capital co-investments
2016
The 80% of corporates that engage in CVC activities, make these investments with other corporates, recognizing the strategic benefits provided by co-investors. Despite the relevance of this phenomenon, no studies focus on the motivations that drive a corporate to syndicate its investments and most important there are no researches that investigate antecedents that drive a corporate in choosing the partner with whom to syndicate the CVC investments. Thus, the aim of this paper is to study why corporates syndicate their CVC investment with a specific partner. Based on the CVC and the alliance literatures we propose a research framework that considers two main elements characterizing a CVC syn…
Fostering novelty while reducing failure: Balancing the twin challenges of product innovation
2016
This paper aims to further our understanding of how the degrees of innovation novelty and innovation failure are connected. It argues that a better understanding of the specific predictors of innovation novelty and failure would improve our understanding of the innovation process and inform R&D managerial interventions to reduce the occurrences of failure and enhance radical innovation. This investigation draws on data on 5387 Spanish manufacturing firms from the 2009 Spanish Community Innovation Survey (CIS). Unlike prior studies which examine product innovation, degree of innovation novelty, and innovation failures in separate models, this study relies on a multivariate model to account f…
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.
The network of global corporate control.
2011
The structure of the control network of transnational corporations affects global market competition and financial stability. So far, only small national samples were studied and there was no appropriate methodology to assess control globally. We present the first investigation of the architecture of the international ownership network, along with the computation of the control held by each global player. We find that transnational corporations form a giant bow-tie structure and that a large portion of control flows to a small tightly-knit core of financial institutions. This core can be seen as an economic “super-entity” that raises new important issues both for researchers and policy make…
Innovation Initiatives in Large Software Companies : A Systematic Mapping Study
2018
Context: To keep the competitive advantage and adapt to changes in the market and technology, companies need to innovate in an organised, purposeful and systematic manner. However, due to their size and complexity, large companies tend to focus on the structure in maintaining their business, which can potentially lower their agility to innovate.Objective:The aims of this study are to provide an overview of the current research on innovation initiatives and to identify the challenges of implementing those initiatives in the context of large software companies.Method: The investigation was primarily performed using a systematic mapping approach of published literature on corporate innovation …
Governance of Ethical and Trustworthy Al Systems: Research Gaps in the ECCOLA Method
2021
Advances in machine learning (ML) technologies have greatly improved Artificial Intelligence (AI) systems. As a result, AI systems have become ubiquitous, with their application prevalent in virtually all sectors. However, AI systems have prompted ethical concerns, especially as their usage crosses boundaries in sensitive areas such as healthcare, transportation, and security. As a result, users are calling for better AI governance practices in ethical AI systems. Therefore, AI development methods are encouraged to foster these practices. This research analyzes the ECCOLA method for developing ethical and trustworthy AI systems to determine if it enables AI governance in development process…
Production of neutron deficient rare isotope beams at IGISOL; on-line and off-line studies
2004
This article reports on recent on-line yield measurements employing the light-ion and heavy-ion reaction-based ion guide systems and new results on a-recoil ion transport properties in ion guides with and without electric fields. In addition, the presently used ion guide designs for fusion evaporation reactions are introduced. The present study investigated different schemes for ion extraction from the gas cell. The addition of an extra ring electrode between the traditional skimmer electrode and the exit hole led to transmission independent of the primary beam intensity as opposed to strong intensity dependence observed earlier with the plain skimmer only. Furthermore, the mass resolving p…
