Implementation and Deployment Evaluation of the DMAMAC Protocol for Wireless Sensor Actuator Networks
2016
Abstract The increased application of wireless technologies including Wireless Sensor Actuator Networks (WSAN) in industry has given rise to a plethora of protocol designs. These designs target metrics ranging from energy efficiency to real-time constraints. Protocol design typically starts with a requirements specification, and continues with analytic and model-based simulation analysis. State-of- the-art network simulators provide extensive physical environment emulation, but still have limitations due to model abstractions. Deployment testing on actual hardware is therefore vital in order to validate implementability and usability in the real environment. The contribution of this article…
Analysis and Visualization of Product Memory Layout in IP-XACT
2017
Modern ASIC and FPGA based embedded products use model based design, in which both hardware and software are developed in parallel. Previously HW was completed first and the information handed over to SW team, typically in the form of register tables. The information was even manually copied to SW code, making any changes error-prone and laborious. IP-XACT is the most feasible standard to model HW also for the SW needs. The HW design connectivity and overall memory layout may change due to component instantiations, configurations and conditional operation states, which makes it difficult to create register tables even for documentation. Current register design tools fall short in serving th…
Knowledge-based verification of concatenative programming patterns inspired by natural language for resource-constrained embedded devices
2020
We propose a methodology to verify applications developed following programming patterns inspired by natural language that interact with physical environments and run on resource-constrained interconnected devices. Natural language patterns allow for the reduction of intermediate abstraction layers to map physical domain concepts into executable code avoiding the recourse to ontologies, which would need to be shared, kept up to date, and synchronized across a set of devices. Moreover, the computational paradigm we use for effective distributed execution of symbolic code on resource-constrained devices encourages the adoption of such patterns. The methodology is supported by a rule-based sys…
Vectors of Pairwise Item Preferences
2019
Neural embedding has been widely applied as an effective category of vectorization methods in real-world recommender systems. However, its exploration of users’ explicit feedback on items, to create good quality user and item vectors is still limited. Existing neural embedding methods only consider the items that are accessed by the users, but neglect the scenario when a user gives high or low rating to a particular item. In this paper, we propose Pref2Vec, a method to generate vector representations of pairwise item preferences, users and items, which can be directly utilized for machine learning tasks. Specifically, Pref2Vec considers users’ pairwise item preferences as elementary units. …
Service innovation methodologies I : what can we learn from service innovation and new service development research? : report no 1 from the TIPVIS-pr…
2007
This report presents a review of service innovation and service development literature. The main purpose of the review is to identify normative implications for service innovation methodologies. Three separate reviews are conducted and reported; an open search review based on specific search terms of relevance to service innovation methodologies, a review of articles in four of the most influential journals on service innovation/service development, and a review focusing contributions applying normative approaches and/or principles. Some of the main conclusions from the review support previous findings that the service innovation process is less formal and that it is more difficult to ident…
Boards' involvement in firm strategy : how can a board be effectively involved in strategy formulation and contribute to firm's successfulness
2006
Masteroppgave i økonomi og administrasjon 2006 - Høgskolen i Agder, Kristiansand The role of the board of directors in firm strategy has been subject of debate for a long time. Many researches have been done from different perspectives particularly on this issue. The purpose of this thesis is to study the role of the board of directors in firm strategy. This study will further investigate on how the board of directors can be effectively involved in strategy formulation for the firms and through this to contribute to the firms' successfulness. Board of directors is a group of individuals who are elected by the shareholders of a corporation and assigned to carry out certain tasks on behalf of…
Information-based detection of nonlinear Granger causality in multivariate processes via a nonuniform embedding technique
2010
We present an approach, framed in information theory, to assess nonlinear causality between the subsystems of a whole stochastic or deterministic dynamical system. The approach follows a sequential procedure for nonuniform embedding of multivariate time series, whereby embedding vectors are built progressively on the basis of a minimization criterion applied to the entropy of the present state of the system conditioned to its past states. A corrected conditional entropy estimator compensating for the biasing effect of single points in the quantized hyperspace is used to guarantee the existence of a minimum entropy rate at which to terminate the procedure. The causal coupling is detected acc…
Evaluation of lens absorbed dose with Cone Beam IGRT procedures
2015
The purpose of this work is to evaluate the absorbed dose to the eye lenses due to the cone beam computed tomography (CBCT) system used to accurately position the patient during head-and-neck image guided procedures. The on-board imaging (OBI) systems (v.1.5) of Clinac iX and TrueBeam (Varian) accelerators were used to evaluate the imparted dose to the eye lenses and some additional points of the head. All CBCT scans were acquired with the Standard-Dose Head protocol from Varian. Doses were measured using thermoluminescence dosimeters (TLDs) placed in an anthropomorphic phantom. TLDs were calibrated at the beam quality used to reduce their energy dependence. Average dose to the lens due to …
Self-knowledge, Authenticity and Obedience
2014
In questo articolo propongo un descrizione del privilegio epistemico dato alla prospettiva della prima persona, alla quale si relaziona un certo tipo di potere su sé stessi. Vorrei mettere in discussione il punto di vista di Robert Dumm e Richard Moran sul problema del soggetto e abbozzare un approccio alternativo. A tal fine, vorrei per prima cosa avvalermi delle nozioni di Bernard William di riconoscimento e di donazione di senso e, in secondo luogo, utilizzare la distinzione di Simone Weil tra i due sensi di obbedienza e la nozione, ad essa associata, di attenzione. In contrasto con la visione di Moran e Dunn, concluderei affermando che un certo tipo di autopercezione è centrale nel nost…
Prototype for Surface Albedo Retrieval Based on Sentinel-3 OLCI and SLSTR Data in the Framework of Copernicus Climate Change
2021
This work describes the different algorithmic steps used to retrieve the first Surface Albedo (SA) product based on Sentinel-3 (S-3) data in the framework of the Copernicus Climate Change Service (C3S). The atmospherically corrected Top-Of-Atmosphere (TOA) reflectances into Top-Of-Canopy (TOC) reflectances are brokered from the Copernicus Global Land Service (CGLS). The TOC reflectances are used to obtain a BRDF model. Next, the spectral and angular integration steps are implemented, which take the latter coefficients as input to produce spectral and broadband albedo quantities. The preliminary quality assessment of BSA broadband albedo for the total shortwave shows good overall spatiotempo…
