Strategies and Techniques for Powering Wireless Sensor Nodes through Energy Harvesting and Wireless Power Transfer
2019
The continuous development of internet of things (IoT) infrastructure and applications is paving the way for advanced and innovative ideas and solutions, some of which are pushing the limits of state-of-the-art technology. The increasing demand for Wireless Sensor Nodes (WSNs) able to collect and transmit data through wireless communication channels, while often positioned in locations that are difficult to access, is driving research into innovative solutions involving energy harvesting (EH) and wireless power transfer (WPT) to eventually allow battery-free sensor nodes. Due to the pervasiveness of radio frequency (RF) energy, RF EH and WPT are key technologies with the potential to power …
Technology management, networking positions and work/life boundaries among working adult students
2021
In this digitalised world, crossing boundaries between life domains is becoming increasingly easy. We are constantly faced with the need to define whether we are online or offline, and technology management is now an integral part of daily life. Technology management, which is affected by the individual's networking position, has different components: connectivity management, online self-presentation and privacy management. The objective of this study is to explore technology management strategies among working adult students. The study identifies three networking positions: socio-affective enthusiasts, context-contingent pragmatists and pragmatic avoiders. These three groups have specific …
A Generalization of Girod's Bidirectional Decoding Method to Codes with a Finite Deciphering Delay
2012
Girod’s encoding method has been introduced in order to efficiently decode from both directions messages encoded by using finite prefix codes. In the present paper, we generalize this method to finite codes with a finite deciphering delay. In particular, we show that our decoding algorithm can be realized by a deterministic finite transducer. We also investigate some properties of the underlying unlabeled graph.
Minimal learning machine in hyperspectral imaging classification
2020
A hyperspectral (HS) image is typically a stack of frames, where each frame represents the intensity of a different wavelength of light. Each spatial pixel has a spectrum. In the classification of the HS image, each spectrum is classified pixel-by-pixel. In some of the real-time applications, the amount of the HS image data causes performance challenges. Those issues relate to the platforms (e.g. drones) payload restrictions, the issues of the available energy and to the complexity of the machine learning models. In this study, we introduce the minimal learning machine (MLM) as a computationally cheap training and classification machine learning method for the hyperspectral imaging classificatio…
The impact on port competition of the integration of port and inland transport services
2015
The performance of the transport chain is important for the efficiency and competitiveness of an economy. In the context of port competition, there has been an increasing cooperation between firms involved in the intermodal transport chain including seaport services. This paper examines the economic incentives and welfare implications to the integration of port activities with inland transport services under inter-ports competition. Although ports find it advantageous to engage in such integration process it may be detrimental to welfare, since shippers’ aggregate surplus decreases – noting that farther away users benefit at the expense of those closer to the ports. Several scenarios not le…
Financial Evaluation of SLA-based VM Scheduling Strategies for Cloud Federations
2017
In recent years, cloud federations have gained popularity. Small as well as big cloud service providers (CSPs) join federations to reduce their costs, and also cloud management software like OpenStack offers support for federations. In a federation, individual CSPs cooperate such that they can move load to partner clouds at high peaks and possibly offer a wider range of services to their customers. Research in this area addresses the organization of such federations and strategies that CSPs can apply to increase their profit.In this paper we present the latest extensions to the FederatedCloudSim framework that considerably improve the simulation and evaluation of cloud federations. These si…
Various Approaches to Early Contractor Involvement in Relational Contracts
2021
Abstract The main rationale for involving contractors is to apply collaboration to mitigate risk and to harvest opportunities to reduce cost and to increase the project owner’s value. In the paper we argue in the applied analytical model that there are four levels of early contractor involvement (ECI), which are 1) Preparation of the project (before sparking off competition); 2) During the procurement phase (development of what to build); 3) Project delivery model (before construction contract, but after the contractor and designers are selected); 4) Project delivery model (where involvement also continues in the execution phase). In the paper we argue that category 4 have the largest poten…
Managing Organizational Growth and Dynamic Complexity
2016
Managers, entrepreneurs and administrators are often reluctant to invest time in order to frame the future of their own organization. They may look too much focused on reducing the complexity of current management. The vision of the future they create in their own minds may remain unchanged even for many years, or may incrementally and ambiguously change, with no effort on learning, on perceiving the early symptoms of crises, and assessing the sustainability of organizational growth rate.
Applying Dynamic Performance Management to Public Emergency Management: An Analysis of the Wenchuan Earthquake
2020
Previous studies in public emergency management confirm that collaboration assumes a relevant role in strengthening society’s capacity to cope with complex phenomena, such as disasters. However, empirical researches on emergency management show problems in performance measurement, mainly in employing narrow measures focusing on the results of single organisations rather than the entire system. Starting from a Chinese earthquake (Wenchuan) case, as an example, we use the dynamic performance management approach to develop a performance framework. This framework aims at investigating the interrelationships of different actors involved in emergency management and designing appropriate public em…
Experimenting lean dynamic performance management systems design in SMEs
2018
Purpose The purpose of this paper is to frame the potential benefits of lean dynamic performance management (PM) systems for small and micro-enterprises. Such systems may exploit the entrepreneur’s tacit knowledge and build on managerial competencies, by incorporating individual attributes into organisational routines. Design/methodology/approach The paper suggests the use of insight models based on the combination of lean PM tools and system dynamics (SD) modelling. Based on a number of exemplary cases, the paper discusses the potential benefits of these models, in respect to four specific contexts: artisan, new company start-up, established firm and micro-giant company. Related to such c…
