From Potential to Implementation: an innovation framework to realize the benefits of soil carbon

This chapter addresses the mismatch between existing knowledge, techniques and management methods for improved soil carbon management and deficits in its implementation. The paper gives a short overview of the evolution of the concept of soil carbon, which illustrates the interactions between scientific, industrial, technical, societal and economic change. It then goes on to show that sufficient techniques are available for the large-scale implementation of soil organic carbon (SOC) sequestration. A subsequent analysis of the bottlenecks that prevent implementation identifies where issues need to be addressed in order to enable robust, integrated and sustainable SOC management strategies.

In this paper, we show that the equation delta u/delta (z) over bar + Gu = f, where the elements involved are in generalized functions context, has a local solution in the generalized functions context.

Effect of veneering material on the deformation suffered by implant-supported fixed prosthesis framework

The aim of this study was to evaluate the deformation suffered by cantilevered implant-supported fixed prostheses frameworks cast in silver-palladium alloy and coated with two occlusal veneering materials: acrylic resin or porcelain. Material and Methods: Two strain gauges were bonded to the inferior surface of the silver-palladium framework and two other were bonded to the occlusal surface of the prosthesis framework covered with ceramic and acrylic resin on each of its two halves. The framework was fixed to a metallic master model and a 35.2 N compression force was applied to the cantilever at 10, 15 and 20 mm from the most distal implant. The measurements of deformation by compression and tension were obtained. The statistical 2-way ANOVA test was used for individual analysis of the experiment variables and the Tukey test was used for the interrelation between all the variables (material and distance of force application). Results: The results showed that both variables had influence on the studied factors (deformation by compression and tension). Conclusion: The ceramic coating provided greater rigidity to the assembly and therefore less distortion compared with the uncoated framework and with the resin-coated framework. The cantilever arm length also influenced the prosthesis rigidity, causing higher deformation the farther the load was applied from the last implant.

An introductory informatics theoretical framework, based on an integrable lattice model using quantized function algebras, for studying DNA-ionized gas interaction system

Usually we observe that Bio-physical systems or Bio-chemical systems are many a time based on nanoscale phenomenon in different host environments, which involve many particles can often not be solved explicitly. Instead a physicist, biologist or a chemist has to rely either on approximate or numerical methods. For a certain type of systems, called integrable in nature, there exist particular mathematical structures and symmetries which facilitate the exact and explicit description. Most integrable systems, we come across are low-dimensional, for instance, a one-dimensional chain of coupled atoms in DNA molecular system with a particular direction or exist as a vector in the environment. This theoretical research paper aims at bringing one of the pioneering ‘Reaction-Diffusion’ aspects of the DNA-plasma material system based on an integrable lattice model approach utilizing quantized functional algebras, to disseminate the new developments, initiate novel computational and design paradigms.

Improving business innovation and research through the application of neuromarketing with ethics: a framework

The objective of this paper is to analyse and to discuss the ethical issues in the field of research known as neuromarketing, a tool used to improve innovation in companies. It uses techniques available to neuroscientists, both newer and more sophisticated ones along with traditional ones, but now for new purposes. From the beginning, this new area has evoked discussions about ethical aspects related to the results presented. Despite the unrestricted controversy surrounding the theme, few studies have discussed ethical issues involved in this line of research in a pragmatic manner. In this sense, this paper seeks to analyse and discuss ethical issues in neuromarketing research through a literature review and the proposal for a framework of ethical mapping. This framework revealed the ethical implications that would be most prominent in certain research situations: the purpose of utilising neuromarketing techniques, organisational type, and industrial sector, among others.

CoolBOT: a component-oriented programming framework for robotics

[EN] Programming software for controlling robotic systems in order to built working systems that perform adequately according to their design requirements remains being a task that requires an important development effort. Currently, there are no clear programming paradigms for programming robotic systems, and the programming techniques which are of common use today are not adequate to deal with the complexity associated with these systems. The work presented in this document describes a programming tool, concretely a framework, that must be considered as a first step to devise a tool for dealing with the complexity present in robotics systems. In this framework the software that controls a system is viewed as a dynamic network of units of execution inter-connected by means of data paths. Each one of these units of execution, called a component, is a port automaton which provides a given functionality, hidden behind an external interface specifying clearly which data it needs and which data it produces. Components, once defined and built, may be instantiated, integrated and used as many times as needed in other systems. The framework provides the infrastructure necessary to support this concept for components and the inter communication between them by means of data paths (port connections) which can be established and de-established dynamically. Moreover, and considering that the more robust components that conform a system are, the more robust the system is, the framework provides the necessary infrastructure to control and monitor the components than integrate a system at any given instant of time.

A comparison of face and facial feature detectors based on the viola-jones general object detection framework

[EN]The human face provides useful information during interaction; therefore, any system integrating Vision- BasedHuman Computer Interaction requires fast and reliable face and facial feature detection. Different approaches have focused on this ability but only open source implementations have been extensively used by researchers. A good example is the Viola–Jones object detection framework that particularly in the context of facial processing has been frequently used.

Esecuzione immediata di frammenti di codice sorgente C# tramite l’utilizzo della .NET Compiler Platform

.NET Compiler Platform è un compilatore per i linguaggi C# e Visual Basic realizzato da Microsoft. L’innovazione apportata da tale strumento è l’introduzione di API che permettono di accedere al compilatore; in particolare, è possibile accedere alle strutture dati utilizzate al suo interno, quali simboli o AST, e controllare e/o modificare il processo di compilazione. Una parte di questo progetto, chiamato anche progetto Roslyn, è focalizzata sull’introduzione dello scripting per il linguaggio C#. In questa trattazione si è interessati a sperimentare le possibilità offerte da tale strumento nel campo dell’esecuzione dinamica di frammenti di codice. Gli obiettivi imposti si collocano nell’ambito della re-ingegnerizzazione e dello sviluppo di software. Tali obiettivi sono la re-implementazione dei filtri di selezione contenuti nel framework Phoenix, utilizzando le API di Roslyn per migliorarne le prestazioni, e la progettazione di un componente che realizzi una console per lo scripting C# dotata della possibilità di riferire dinamicamente librerie. Le API di compilazione si rivelano essere non propriamente adatte all’esecuzione immediata di frammenti di codice, nonostante ciò, è possibile, appoggiandosi alla reflection, utilizzarle per giungere a questo risultato. Lo scripting, invece, si rivela uno strumento dalle grandi potenzialità nel suddetto ambito.
