Security Threats in ZigBee-Enabled Systems: Vulnerability Evaluation, Practical Experiments, Countermeasures, and Lessons Learned
2013
In this paper, two practical attacks against ZigBee security are proposed and the latter one is also carried out in our laboratory environment. The attack scenarios are based on utilizing several vulnerabilities found from the main security components of ZigBee technology. The first attack is based on sabotaging the ZigBee End-Device by sending a special signal that makes it wake-up constantly until the battery runs out. The second attack is based on exploiting the key exchange process in ZigBee when using the Standard Security level defined by the ZigBee specification: we also demonstrate with experimental figures that attacks against ZigBee-enabled devices become practical by using our at…
The rationale for and practice of EIA follow-up: an analysis of Finnish road projects
2015
Follow-up is often considered to be a weak or even missing element in environmental impact assessment (EIA). Though it is recognized that follow-up practices could provide useful opportunities to learn from projects’ actual consequences, the practice is criticized for not achieving this goal. In this paper, we aim to clarify the relationship between the theoretical rationale for EIA follow-up and the actual practices carried out in a Finnish EIA context. An empirical analysis was performed with follow-up documents. The findings indicate that follow-ups focused on dealing with environmental impacts related to the physical environment, e.g., flora, fauna, and ground and surface waters. Social…

Oral Squamous Cell Carcinoma on Gingiva, Edentulous Ridge, and Retromolar Pad: A Case Series
2021
(1) Background: Gingival cancer has a significant incidence and is often diagnosed at advanced stages. The aim of this paper is to highlight its clinical aspects on the basis of a case series analysis in order to promote awareness and improve the diagnosis process. (2) Methods: Oral cancers diagnosed and treated at three Italian University Hospitals over ten years were retrospectively investigated. Cancer location on the gingiva, edentulous ridge, and retromolar pad was addressed. Data regarding clinical features, stage at the diagnosis, and time from presenting symptoms to first medical consultation were retrieved. (3) Results: Thirty-three cancers located on the gingiva, edentulous ridge,…
IS evolution benefit assessment: Challenges with economic investment criteria
2007
Maintenance and system evolution activities have a significant role in the information system (IS) life cycle. It has been estimated that approximately 80% of the total IT expenses are allocated for maintenance activities [20]. According to Lehman’s first law, maintenance is necessary, because software needs to be continuously improved or it will get out of date and cannot respond to the requirements of its environment [19]. Despite the importance of IS evolution investments, there is a gap between the IT related costs and company profitability [27]. Brynjolfssen [10] described this as a productivity paradox: information technology utilization has increased since the 70’s but simultaneously…
Revista electrónica de investigación y evaluación educativa
2010
The aim of this work is the development of a model that can be used as a framework for evaluators and PhD tribunal members, either during the previous administrative processing phase or at the actual exposition and viva on doctoral dissertations. To this end, once reviewed the existing literature and normative, a new proposal is laid out on the main aspects and criteria to be analysed and assessed from any given scientific work, thus introducing a tool that facilitates and specifies this work. Our model is intended to be an open proposal on which we would welcome any contribution and suggestion. El objetivo del presente trabajo es la elaboración de un modelo que pueda ser utilizado como mar…
La mejora de la calidad normativa Estudio comparado de procedimientos para la elaboración de normas e instrumentos para la mejora y evaluación de su …
2020
La mejora de la calidad normativa y su posterior evaluación forman parte de las preocupaciones actuales de nuestro Derecho público. No obstante, hasta fechas muy recientes, principalmente por influencia de modelos anglosajones y, muy particularmente, de la Unión Europea, no se han ido introduciendo medidas en este ámbito, y su desarrollo hasta hoy tampoco ha sido demasiado satisfactorio. El presente estudio analiza los problemas y las ineficiencias del modelo español para la mejora de la calidad normativa y trata de sistematizar una serie de propuestas a través del diseño de un nuevo modelo de producción y evaluación normativa. Para ello, no solo se analiza críticamente el desarrollo legisl…

Evaluation des simulations spatiales
2006
The general topic is the evaluation of prospective scenarios for urban planning, especially for the management of urban built up areas. Several models of land-use and land-cover change (LUCC), based on different assumptions, allow producing realistic simulations of urban growth. Three ways can be distinguished for measuring the quality of modelings: 1. The choice of a model and its calibration; 2. The validation (showing if results are realistic); 3. The evaluation (showing if results respect defined planning goals). Measurement methods must be associated to these three steps.
