An experimental testbed of an Internet of Underwater Things
2020
A number of critical features have so far slowed down the realization of an Internet of Underwater Things. The most relevant of these aspects are related to the unreliability of the communication channel, the long propagation delay and the effect of severe multi-path and fading. This paper presents the design and development of a hybrid underwater-terrestrial IoT where different underwater sensors collect heterogeneous data and use marine acoustic modems to send information to a gateway device; this is able to set up a long distance link, implemented through a LoRaWAN connection, to forward data to a remote cloud for further processing. Performance of this system has been tested in a real s…
A global network for the control of snail-borne disease using satellite surveillance and geographic information systems
2001
Abstract At a team residency sponsored by the Rockefeller Foundation in Bellagio, Italy, 10-14 April 2000 an organizational plan was conceived to create a global network of collaborating health workers and earth scientists dedicated to the development of computer-based models that can be used for improved control programs for schistosomiasis and other snail-borne diseases of medical and veterinary importance. The models will be assembled using GIS methods, global climate model data, sensor data from earth observing satellites, disease prevalence data, the distribution and abundance of snail hosts, and digital maps of key environmental factors that affect development and propagation of snail…

INTERNET USE FOR SHOPPING IN LATVIA: FINDINGS BY RECENT SURVEY
2019
Recent developments of internet applications and increase in application of various information technologies have supported fast development of internet shopping worldwide and also important topics for academic researchers. Aim of the research: check findings of recent preferences by customers on internet shops and factors for internet shop choice, different aspects on internet shopping and comparisons with academic research results in other countries. Tasks: scientific findings studies and empirical investigations on customer preferences and determining factors for choice of different factors in internet shopping. Research methods used: recent scientific publications studies, studies of st…
ISAdetect
2020
Static and dynamic binary analysis techniques are actively used to reverse engineer software's behavior and to detect its vulnerabilities, even when only the binary code is available for analysis. To avoid analysis errors due to misreading op-codes for a wrong CPU architecture, these analysis tools must precisely identify the Instruction Set Architecture (ISA) of the object code under analysis. The variety of CPU architectures that modern security and reverse engineering tools must support is ever increasing due to massive proliferation of IoT devices and the diversity of firmware and malware targeting those devices. Recent studies concluded that falsely identifying the binary code's ISA ca…
Designing a Simulation Model of a Self-Maintaining Cellular System
1999
This paper deals with the problem of finding a suitable framework for designing computer simulations that could help us determine the minimal requirements (both material and organizational) for the origin of the first full-fledged autonomous systems. The design of a particular model that takes into account some fundamental thermodynamic requirements is offered and discussed. Behind this work, there is a belief that Artificial Life models can inform biology on several fundamental questions (such as the origin and definition of life) but only provided that they assume more realistic and grounded premises to lead us to more conclusive results.
Mobility and Spatio-Temporal Exposure Control
2013
Modern risk assessment methods cover many issues and encompass both risk analysis and corresponding prevention/mitigation measures.However, there is still room for improvement and one aspect that may benefit from more work is “exposure control”.The “exposure” an asset experiences plays an important part in the risks facing the asset.Amongst the aspects that all too regularly get exposed is user identities and user location information,and in a context with mobile subscriber and mobility in the service hosting (VM migration/mobility) the problems associated with lost identity/location privacy becomes urgent.In this paper we look at “exposure control” as a way for analyzing and protecting use…
Alone at home
2008
Recently there has been much public discussion about children spending long afternoons alone at home. It has been claimed that spending a lot of time alone makes children vulnerable to many kinds of risk behaviour, such as smoking, use of alcohol and drugs, depression and poor school performance. Concerns have also been voiced about children’s unsupervised television watching, playing of computer games and surfing on the Internet. Yet, do we actually know how long the times are that children do spend alone at home and what do they do during that time? The purpose of this paper is to study how much time youngsters in Finland spend alone at home, who are the youngsters who are alone and what …
Project Risk Register Analysis Based on the Theoretical Analysis of Project Management Notion of Risk
2016
Abstract The aim of the current research is to examine publicly available project risk registers to find correlations between the project management theory, especially project risk management, and practical results of real project risk management – the risk registers publicly available on the Internet. In the research, the author has analysed the compliance between the theories of the project risk management described in the “Aid Delivery Methods. Volume I. Project Cycle Management Guidelines” and “Caltrans Project Risk Management Handbook, Threats and Opportunities, Second Edition, Revision 0” and the project risk registers. In the previous studies, the author concluded that after analysin…
Why Some Internet Users Don’t Buy Air Tickets Online
2010
This work attempts to identify the determinant variables that make some Internet users not to buy airline tickets online. The Technology Acceptance Model (TAM) and the Theory of Planned Behaviour (TPB) have been used as the conceptual reference framework, with the addition of the influence of perceived risk and trust. The results of the empirical study of Internet users who never have purchased an airline ticket online suggest that both subjective norm and attitude have a direct influence on airline ticket purchase intention. Ease of use has also proved to be a significant variable, because it has an indirect influence on behaviour through perceived usefulness, trust and risk. Risk, trust a…
