Resource Allocation for Multi-Access Edge Computing with Fronthaul and Backhaul Constraints

2021

Edge computing is able to provide proximity solutions for the future wireless network to accommodate different types of devices with various computing service demands. Meanwhile, in order to provide ubiquitous connectivities to massive devices over a relatively large area, densely deploying remote radio head (RRH) is considered as a cost-efficient solution. In this work, we consider a vertical and heterogeneous multiaccess edge computing system. In the system, the RRHs are deployed for providing wireless access for the users and the edge node with computing capability can process the computation requests from the users. With the objective to minimize the total energy consumption for process…

Ambiguities in organizations and the routines of behavior and change

2015

Purpose– The aim of this article is threefold: the primary aim is conceptual by outlining two ideal-typical ideas about organizational life. These models offer rival ideas about how organizations balance seemingly conflicting patterns of behaviour and change in everyday life. The second ambition of the article is to outline a theoretical approach of organizational life arguing that even fairly loosely coupled organizations may be profoundly patterned by everyday routines as much as by ambiguity. The third and final ambition is to offer empirical illustrations from organizations that are often considered as archetypes of loose coupling and ambiguities: jazz orchestras and university organiza…

Bandwidth allocation and pricing in multimode network

2006

This paper presents adaptive resource sharing model that uses a revenue criterion to allocate network resources in an optimal way. The model ensures QoS requirements of data flows and, at the same time, maximizes the total revenue by adjusting parameters of the underlying scheduler. Besides, the adaptive model eliminates the need to find the optimal static weight values because they are calculated dynamically. The simulation consists of several cases that analyse the model and the way it provides the required QoS guarantees. The simulation reveals that the installation of the adaptive model increases the total revenue and ensures the QoS requirements for all service classes.

Water Conflict and Water Management in the Middle East

2004

“Water is Life”: this is often forgotten in countries with abundant water ressources. As a ressource it only gains importance once it is in short supply or once its quality declines. In the case of shortage the battle for water becomes inevitable. At the moment we have up to 200 conflicts of border-crossing water systems in the world. The Middle East is considered to be a typical example of this politically significant problem

Cropland and grassland management

2014

According to the latest National Inventory, the Italian agricultural sector is a source of GHGs with 34.5 Mt of CO2 eq in 2009, corresponding to 7 % of the total emissions (excluding LULUCF). In particular, more than half (19.1 Mt of CO2 eq) are N2O emissions from soils. Although the national methodology is in accordance with Tier 1 and 2 approaches proposed by the IPCC (2006), still empirical emission factors are used to assess the emission from fertilizer (e.g. 0.0125 kg N2O–N kg−1 N from synthetic fertilizers). Disaggregated data at sub-national level, including models and inventory measurement systems required by higher order methods (i.e. Tier 3), are not available in Italy so far and …

The key stages in the history of the living world may be summed up as follows: formation of the major types of body plan at the start of the Cambrian, with the appearance of the last, the vertebrates, during the upper Cambrian. Thereafter evolution took place within these plans through “modulations” exploiting a number of possibilities.

Cancer screening and health system resilience: Keys to protecting and bolstering preventive services during a financial crisis

2012

The aim of this paper is to elucidate the rationale for sustaining and expanding cost-effective, population-based screening services for breast, cervical and colorectal cancers in the context of the current financial crisis. Our objective is not only to promote optimal delivery of high-quality secondary cancer prevention services, but also to underline the importance of strengthening comprehensive cancer control, and with it, health system response to the complex care challenges posed by all chronic diseases. We focus primarily on issues surrounding planning, organisation, implementation and resources, arguing that given the growing cancer burden, policymakers have ample justification for e…

New evidence on accelerator performance based on funding and location

2020

Seed accelerators (SAs) appear as a more advanced version of business incubators. These for-profit organizations in exchange of equity, help setting new start-ups by providing mentoring and funding during its first months. Due to their emergent nature, the impact and expectations of SAs remains largely unknown. Therefore, the purpose of this study is to throw new light on this field by empirically assessing for the first time the performance and prospects of these organizations through a survey of 116 SAs.,A model based on the Business Incubators literature is built with four categories covering size, location, age and profitability variables, leading to two hypotheses to be tested empirica…

CEO-TMT interaction: do tenure and age affect ambidexterity dynamism?

2013

The aim of this study is to clarify the influence of the CEO, the top management team and their interactions on the dynamism of organisational ambidexterity. We argue that ambidexterity is a dynamic capability that enables firms to become aligned with their environment. We examine this phenomenon in the context of the current economic crisis, with particular reference to SMEs. We propose tenure and age as characteristics of business elites that help to explain ambidexterity dynamism. In SMEs, the tenure and age of CEOs and interactions with top management team characteristics play a decisive role in the decision-making process, and therefore, in how the company adapts its orientation to amb…

SUSTAINABLE AGRICULTURE MANAGEMENTS TO CONTROL SOIL EROSION

2021

[EN] High rates of soil erosion compromise sustainable agriculture. In rainfed agricultural fields, erosion rates several orders of magnitude higher than the erosion rates considered tolerable have been quantified. In Mediterranean rainfed crops such as vineyards, almonds and olive groves, and in the new sloping citrus and persimmon plantations, the rates of soil loss make it necessary to apply measures to reduce them to avoid collapse in agricultural production. Managements such as weeds, catch crops and mulches (straw and pruning remains) are viable options to achieve sustainability. This work applies measurements through plots, simulated rainfall experiments and ISUM (Improved Stock-Unea…
