Manipulation Process

This paper discusses the design of virtual probe tip models for use in a nano-manipulation research test-bed (NMRT). The proposed NMRT would help study the feasibility of a given manipulation technique in a virtual environment before physical experiments. For example, NMRT would be able to help users determine if a specific kind of probe tip can be used to pull out a nano-particle from a given substrate. A virtual probe tip model (for instance) would consider the given geometry and material of probe tip and simulate its behavior in a manipulation application in a physics based virtual reality environment. Such a virtual analysis and overall approach would result in considerable saving in time and financial resources with substantial application potential in medical and biotechnology fields where nanoparticle manipulation is useful. Expandability of the NMRT is made possible by designing an ‘information oriented’ or ‘information intensive’ model for a target set of nano-manipulation activities, which maps in detail various attributes related to a target nano-manipulation process [1]. In this approach, information models based on “engineering Enterprise Modeling Language” (eEML) are used. For example, consider an existing information model for interaction of a probe tip with a spherical particle; a user can use an existing information model, or modify it quickly to study the impact of two approaches (eg. manipulation strategy-A versus strategy-B, which may apply a different probe-tip for gripping). For a target nano-manipulation process (for example, the assembly of nano particles using an Atomic Force Microscope probe as a gripper), an information model can represent the core attributes influencing the target process; influencing criteria including constraints, information inputs, and physical inputs can be modeled explicitly and used to drive a target analysis or simulation activity.

The Impact

The use of Building information modelling for the design and construction phase of a building has been thoroughly looked into by researchers and practitioners and there is evidence to support that it is beneficial for reducing cost, time and improving communication. Yet the potential use of BIM for the operational and management phase (Facilities management), besides maintenance schedules and equipment information and location, is still not clearly identified. The UK Government, institutional clients and major private owners are now demanding for BIM for new construction and major refurbishment but given that 70-75% of the current UK building stock will still be in use in 2050, a significant part of the existing facilities will not have an information model till the next major refurbishment, creating a major gap in the built environment. This paper presents a new framework aimed at creating information models for facilities management requiring minimal BIM skills and discusses the impact that models created for the operational stage would have on the whole life cycle of a building.

This article deals with the combined effect of micro and nano fillers on mechanical, thermal and morphological behavior of glass-basalt hybrid composites (GB). Three material systems were selected for the study: glass-basalt fiber reinforced 80 wt. % PA66 – 20 wt. % PTFE blend (GB), GB/Micro fillers (MoS2, SiC, Al2O3) (GBM) and GBM/nano fillers (TiO2) (GBN). It has been revealed from the experimentation that the effect of micro fillers deteriorated the mechanical behavior of micro composites (GBM). But the combined effect of micro and nano fillers slightly impaired the mechanical behavior of nano composites. The synergistic effect of micro and nano fillers constrained the loss of strength of nano composites. But the impact strength of nano composites has been improved due to hybrid fillers effect. The hybrid effect of fillers significantly improved the thermal stability of nano composites. Further, it is observed from the morphology that the fractured surfaces were characterized by fiber pull out and fiber overlapping, severe deformation and agglomeration of nano particles.

This chapter discusses whether the European Union has a distinctive take on, and may make a particular contribution to, global governance, as well as the reverse image of the impact that global governance has in the development of integration in Europe. This includes a focus on collective norms and interests as expressed through common institutions, policies, and activities. In doing so, the chapter compares and contrasts the evolution of a supranational order in Europe with the growth of global regimes and the emergence of a multipolar world, and explores the nature of the EU’s relationships with other global powers and regions. In a final section, the chapter asks whether the EU’s relationship with global developments is best seen as a test-bed for new ideas, procedures, and concepts; a construction for the defence of a privileged way of life; or an archaic remnant of a different era.

Abstract The Nationwide Network of Networks (NNoN) concept was introduced by the National Research Council to address the growing need for a national mesoscale observing system and the continued advancement toward accurate high-resolution numerical weather prediction. The research test bed known as the Dallas–Fort Worth (DFW) Urban Demonstration Network was created to experiment with many kinds of mesoscale observations that could be used in a data assimilation system. Many nonconventional observations, including Earth Networks and Citizen Weather Observer Program surface stations, are combined with conventional operational data to form the test bed network. A principal component of the NNoN effort is the quantification of observation impact from several different sources of information. In this study, the GSI-based EnKF system was used together with the WRF-ARW Model to examine impacts of observations assimilated for forecasting convection initiation (CI) in the 3 April 2014 hail storm case. Data denial experiments tested the impact of high-frequency (5 min) assimilation of nonconventional data on the timing and location of CI and subsequent storm evolution. Results showed nonconventional observations were necessary to capture details in the dryline structure causing localized enhanced convergence and leading to CI. Diagnosis of denial-minus-control fields showed the cumulative influence each observing network had on the resulting CI forecast. It was found that most of this impact came from the assimilation of thermodynamic observations in sensitive areas along the dryline gradient. Accurate metadata were found to be crucial toward the future application of nonconventional observations in high-resolution assimilation and forecast systems.

The results of the development of an information model for the personality’s social portrait formation are presented. The modelling has been carried out using OSINT technology that is the technology of legal obtaining and using open source information. In the result of the analysis, it has been found out that the social portrait is a heterogeneous semantic network consisting of personalized data. It has been defined that people organize formal and official communities of various orientations and the number of such communities associated with a particular person is practically unlimited. When formalizing the decision-making process, the concept of a group social portrait (GSP) has been introduced, which takes into account the community’s social tendencies united by certain common properties, group members' interpersonal interactions and their behavioural patterns. The obtained information models of personal and group social portraits let to take into account all the main properties of the objects under study, their tonality and significance, as well as to conduct an analysis of the implicit dependencies determination. The next step is to move on to considering the diversity of the digital social environment elements.

The present paper presents an analysis on the role of Natural Gas (NG) in Portugal facing the new requirements. The analyses is based on the economic, societal and environmental aspects, being the major reasons to align the Government strategy, define policies and reproduce the EU directives. The analyses do not reflect on the pandemic and financial crisis because the author considers that these factors are outside of the energy system and have not been steady along the period in study, thereby it can mislead the conclusions. This study relies mostly on non-empirical research, in which the research adopted both inductive and deductive reasoning to theorize logical assumptions about the Portuguese energy market. Building on reflection and personal observation on the field, the researchers carried out this article by gathering relevant data (i.e., statistics) through critical studies, systematic review of literature and meta-analysis on the theme. Therefore, the methodology used is based mainly on qualitative exploration of secondary sources and data, out of which one will pull out insights. The novelty of the study is to take in consider-ation all the above factors and produce results that are more adequate to reality, as all of them are interconnected and by changing one of them it will be changes in the remain. The open literature mainly focusses on the economic, the energetic, the social or the environmental aspects and neglects the others. One can conclude that there is economic advantage on efficiently distributing and consuming NG. Also, the impact of NG on a society welfare is positive. Last, the NG brings flexibility to the grid, which is more and more important in the perspective and ambition to increase the share of intermittent renewable energies.

The Impact

The aim of the study is to try to analyze the most common mechanisms of impulse noise impact on data transmitted in the symbols of single-carrier and multi-carrier modulation systems. The paper solves the problem of a qualitative analysis of the destructive effect of impulse noise on the possibility of restoring symbols of digital modulation systems operating on the basis of a copper cable infrastructure. The performed analysis uses induction as research methods, which allows extending isolated special cases of symbol distortion to the generalized procedures for degrading the transmitted information quality; an analogy involving the consideration of similar mechanisms for modifying data in a stream of modulated signals with one carrier and multiple ones. The novelty of the findings obtained consists in generalizing the process of decoding errors due to noise bursts to the systems with one carrier and several ones, as well as in differentiating the influence of the noise pulse duration and power on the transmitted symbols. As the main findings of the work, we can note the identification of the impact ambiguity of impulse noise on the transmission systems of digital subscriber lines, expressed in the necessity to take into account while analyzing both the parameters of the noise itself and the type of modulation, and the energy and time relationships between the useful signal and noise. Thus, the work shows that the destructiveness degree of the impulse noise impact on the transmission system of a digital subscriber line is determined by several characteristics that should be taken into account when developing mechanisms for the protection against interference, or, conversely, to justify the inappropriateness of their use.

Bird Collisions

Green buildings should respect nature and endeavor to mitigate harmful effects to the environment and occupants. This is often interpreted as creating sustainable sites, consuming less energy and water, reusing materials, and providing excellent indoor environmental quality. Environmentally friendly buildings should also consider literally the impact that they have on birds, millions of them. A major factor in bird collisions with buildings is the choice of building materials. These choices are usually made by the architect who may not be aware of the issue or may be looking for guidance from certification programs such as LEED. As a proof of concept for an educational tool, we developed a software-assisted approach to characterize whether a proposed building design would earn a point for the LEED Pilot Credit 55: Avoiding Bird Collisions. Using the visual programming language Dynamo with the common building information modeling software Revit, we automated the assessment of designs. The approach depends on parameters that incorporate assessments of bird threat for façade materials, analyzes building geometry relative to materials, and processes user input on building operation to produce the assessment.

The Impact

Soft grasping of random objects in unstructured environments has been a research topic of predilection both in academia and in industry because of its complexity but great practical relevance. However, accurate modeling of soft hands and fingers has proven a difficult challenge to tackle. Focusing on this issue, this article presents a detailed mathematical modeling and performance analysis of parallel grippers equipped with soft fingers taking advantage of the fin ray effect (FRE). The FRE, based on biomimetic principles, is most commonly found in the design of grasping soft fingers, but despite their popularity, finding a convenient model to assess the grasp capabilities of these fingers is challenging. This article aims at solving this issue by providing an analytic tool to better understand and ultimately design this type of soft fingers. First, a kinetostatic model of a general multi-crossbeam finger is established. This model will allow for a fast yet accurate estimation of the contact forces generated when the fingers grasp an arbitrarily shaped object. The obtained mathematical model will be subsequently validated by numerically to ensure the estimations of the overall grasp strength and individual contact forces are indeed accurate. Physical experiments conducted with 3D-printed fingers of the most common architecture of FRE fingers will also be presented and shown to support the proposed model. Finally, the impact of the relative stiffness between different areas of the fingers will be evaluated to provide insight into further refinement and optimization of these fingers.
