A Forecasting Support System Based on Exponential Smoothing
2010
This chapter presents a forecasting support system based on the exponential smoothing scheme to forecast time-series data. Exponential smoothing methods are simple to apply, which facilitates computation and considerably reduces data storage requirements. Consequently, they are widely used as forecasting techniques in inventory systems and business planning. After selecting the most adequate model to replicate patterns of the time series under study, the system provides accurate forecasts which can play decisive roles in organizational planning, budgeting and performance monitoring.
Reflection 2008: The State of Science, Religion and Consciousness
2008
2008 is a year in which the world’s economical, financial and even political systems are going through unprecedented turmoil and earth-shaking transformations. Yet, it seems that nothing has changed in Science except that many scientists are sadly loosing there jobs and/or funding. Religion also seems to be stagnant with the exceptions that various hastened prophecies of 2012 are flourishing and charitable contributions are in drastic declines. Under these historical, uncertain, sad but hopeful circumstances, it is appropriate and even urgent that we further reflect on the state of Science and Religion. It is also appropriate that we reflect on the state of consciousness research because ou…
Exploiting Numerical Behaviors in SPH.
2010
Smoothed Particle Hydrodynamics is a meshless particle method able to evaluate unknown field functions and relative differential operators. This evaluation is done by performing an integral representation based on a suitable smoothing kernel function which, in the discrete formulation, involves a set of particles scattered in the problem domain. Two fundamental aspects strongly characterizing the development of the method are the smoothing kernel function and the particle distribution. Their choice could lead to the so-called particle inconsistency problem causing a loose of accuracy in the approximation; several corrective strategies can be adopted to overcome this problem. This paper focu…
Model-Driven Development Approach for Providing Smart Home Services
2009
Smart home is about the application of automation techniques for the comfort and security of residents' privately owned homes. In a smart home environment, different and independent embedded devices provide services that can be freely used by others, in the sense of service invocation. This paper presents our idea of using Model Driven Development (MDD) for the composition of existing services, by which we aim at demonstrating how new smart home services will be promoted.
A framework for IoT service experiment platforms in smart-city environments
2016
Cities provide an excellent platform for gathering and detection of massive amount of data from cities and citizens. Emergence of new digital technologies inspires not only city governments but also city residents, researchers, companies and other stakeholders in discovering and creating new innovative solutions to solve urban challenges and improve peoples´ everyday life. Developing novel Internet of Things (IoT) solutions for cities and citizens requires facilities where IoT applications and services can be tested and experimented. The challenge for many smart-city test and experimentation platforms (TEPs), like living labs, has been the lack of sustainable value creation model. This has …
An RF Wireless Power Transfer system to power battery-free devices for asset tracking
2019
Internet of Things (IoT) and Wireless Sensor Networks (WSN) infrastructures are becoming more and more available and diffused. One major outcome is the development of new services that help to make everyday life easier and better. One of those to which this paper reserves special attention is asset tracking which refers to the method of tracking physical assets. This service is very well based on IoT infrastructure and, due to the enormous number of objects to be traced, desperately needs the availability of inexpensive tags with sensing capabilities, that can be conveniently monitored from a long distance and require no maintenance. For this, engineers are called to face very challenging i…
Kata Containers: An Emerging Architecture for Enabling MEC Services in Fast and Secure Way
2019
New coming applications will be only possible through Mobile Edge Servers deployed in proximity of the mobile users. Due to the user's mobility and server's workload, service migration will be an integral part of the services. For this reason, a standardized architecture should be designed to accomplish a workload migration in a secure and timely manner. Most research done to date has focused on the use of either virtual machine (VM) or container or a mix of both recently. A final solution might be an architecture only having the advantages of both technologies as the security of the VM and the speed of the containers. Custom solutions, actually, by using both technologies, need continuous …
Light project e strumenti digitali: per una fruizione narrativa dei beni culturali
2016
Lighting design, exhibition design and communication design play together a very important and significant role during the processes related to conservation, requalification, restoration, promotion and fruition of cultural heritage. Through the selection of some projects of light design, in association with the use of new technologies and digital tools, the article describes new design processes for the fruition and promotion of cultural heritage. Expanding the concepts of conservation, fruition and promotion of cultural heritage, these projects encourage a very deep relation between the cultural heritage and the visitor, who moves in a “cognitive and emotional space increased” by the combi…
The appraisal smoothing in the real estate indeces
2013
The appraisal smoothing is the phenomenon in which the valuation of a property, based on the judgments of appraisers (expertise) rather than on the collection of market data, is influenced by previous valuations performed by the same expert. The most obvious consequence of the exercise of expertise is the tendency to generate in the time a smoothing in the estimated value. This is the first experimental application of the appraisal smoothing theory in Italy. The general spread of real estate valuations, based on prices and average prices refer to a single commercial parameter (usually the surface), generates the natural suspicion that the smoothing effect could be widely disseminated and th…
Energy savings through integration of the illumination natural and artificial, using a system of automatic dimming:Case study
2013
The reduction of electrical energy consumption in buildings is a subject of great interest in the international scientific community. In buildings with a lot of available natural light, designed with large glazed surfaces, the artificial lighting system is often oversized and cannot be divided into segments to meet lighting demands during daylight hours. This article presents an experimental study, conducted in a university lecture hall that has a glazed surface covering the whole wall at one end, which provides a level of internal illumination that is only sufficient for the area next to the window itself, even when the outside lighting conditions are very bright. It is therefore necessary…
