Implementation of a deduplication cache mechanism using content-defined chunking

Many application programs in data-intensive science read and write large files. Large data consume significant memory because the data is loaded into the page cache. Since memory resources are critically valuable in data-intensive computing, reducing the memory footprint consumed by file data is essential. In this paper, we propose a cache deduplication mechanism with content-defined chunking CDC for the Gfarm distributed file system. CDC divides a file into variable-size blocks chunks based on the contents of the file. The client stores the chunks in the local file system as cache files and reuses them during subsequent file accesses. Deduplication of chunks reduces the amount of transmitted data between clients and servers, and reduces storage and memory requirements. The experimental results demonstrate that the proposed mechanism significantly improves the performance of file-read operations and that the introduction of parallelism reduces the overhead of file-write operations.
Simulation and study of large-scale bacteria-materials interactions via BioScape enabled by GPUs

Biological systems encompass complexity that far surpasses many artificial systems. Modeling and simulation of large and complex biological systems is a computationally intensive challenge. We present a GPU based simulation framework in a reactive environment in 3D space, along with the modeling language, BioScape, in order to describe various biological processes. We also present an efficient computational framework to study the interactions enabled by the massively parallel processing capability of the GPUs. Our driving example is a bio-triggered drug delivery system for infection-resistant medical implants. The modeling and simulation framework presented here will help in identifying biological targets and materials to treat biomaterials associated bacterial infections. The computational framework will offer a deeper insight into various biological processes compared to traditional modeling via implicit differential equations, and help us observe the key events as they unfold.
Evaluation of Accuracy and Stability of the Classical SPH Method Under Uniaxial Compression

The accuracy and stability of the classical formulation of the smoothed particle hydrodynamics (SPH) method for modelling compression of elastic solids is studied to assess its suitability for predicting solid deformation. SPH has natural advantages for simulating problems involving compression of deformable solids arising from its ability to handle large deformation without re-meshing, complex free surface behaviour and tracking of multiple material interfaces. The ‘classical SPH method’, as originally proposed by Monaghan (in Ann Rev Astron 30:543–574, 1992, Rep Prog Phys 68:1703–1759, 2005), has become broadly established as a robust method in different areas, especially involving fluid flows. However, limited attention has been paid to understanding of its numerical performance for elastic deformation problems. To address this, we evaluate the classical SPH method to explore its stability, accuracy and convergence and the effect of numerical parameters on elastic solutions using a generic uniaxial stress test. Short term transient and long term uniform state SPH solutions agree well with those from the finite element method (FEM). The SPH elastic deformation solution showed good convergence with increasing particle resolution. The tensile instability stabilisation method was found to have little impact on the solution, except for higher values of the correction factor which then produce small amplitude benign artificial banded stress patterns. The use of artificial viscosity is able to eliminate the instability and improve the accuracy of the solutions. Overall, the classical SPH method appears to be robust and suitable for accurate modelling of elastic solids under compression.
A study on Train Operator’s Behavior in the Automated Train

An introduction of automated train achieved a high level task. However it became a factor causing another errors. In this study, behavior of train operators towards preference of automated operation and management technic is examined. A survey was carried out and analyzed targeting train operators with ATO(automated train operation) system in Seoul metro line 2.The survey showed that the train operators prefer automation of train but they distrust automation system. As a result of analysis train operators feel more need of “pointing and calling” and cross-checking between crew members when they operate train with ATO system more likely than when they operate train manually. And this analysis value on train operators under 4 years’ work experience was highest.
SCROLL COMPRESSOR

The present invention discloses a scroll compressor. At least two shrink belts (23′, 23″, 26, 26′, 28, 28′) are provided around the outer periphery of said fixed scroll between the outer periphery of said fixed scroll (2) and the inner wall surface of the upper cap (1) of the scroll compressor. The at least two shrink belts are annular, and are in interference fit between the outer periphery of said fixed scroll and the inner wall surface of the upper cap. The at least two shrink belts include a main shrink belt (23′, 23″, 28) and an assistant shrink belt (26, 26′, 28′). The main shrink belt and the assistant shrink belt are arranged side by side in the axial direction, that is, in the vertical direction of the fixed scroll, and the main shrink belt and the assistant shrink belt are spaced apart from each other by a distance. In this way, it is allowed to add other special structure (e.g., an additional fluid passage) to the fixed scroll, reduce the deformation of the fixed scroll, and improve the performance and the reliability of the scroll compressor.

Robots understanding their actions by imagining their effects

Today's robots are good at executing programmed motions, but they do not understand their actions in the sense that they could automatically generalize them to novel situations or recover from failures.  IMAGINE seeks to enable robots to understand the structure of their environment and how it is affected by its actions.  ""Understanding"" here means the ability of the robot (a) to determine the applicability of an action along with parameters to achieve the desired effect, and (b) to discern to what extent an action succeeded, and to infer possible causes of failure and generate recovery actions.

The core functional element is a generative model based on an association engine and a physics simulator.  ""Understanding"" is given by the robot's ability to predict the effects of its actions, before and during their execution.  This allows the robot to choose actions and parameters based on their simulated performance, and to monitor their progress by comparing observed to simulated behavior.

This scientific objective is pursued in the context of recycling of electromechanical appliances.  Current recycling practices do not automate disassembly, which exposes humans to hazardous materials, encourages illegal disposal, and creates significant threats to environment and health, often in third countries.  IMAGINE will develop a TRL-5 prototype that can autonomously disassemble prototypical classes of devices, generate and execute disassembly actions for unseen instances of similar devices, and recover from certain failures.  For robotic disassembly, IMAGINE will develop a multi-functional gripper capable of multiple types of manipulation without tool changes.

IMAGINE raises the ability level of robotic systems in core areas of the work programme, including adaptability, manipulation, perception, decisional autonomy, and cognitive ability.  Since only one-third of EU e-waste is currently recovered, IMAGINE addresses an area of high economical and ecological impact.
Analysis of the effect of the tumour microenvironment on t cell functional phenotype

A successful adaptive immune response requires T cells to be able to adopt a specific metabolic phenotype. However, in
diseases such as cancer or those associated with chronic inflammation, the metabolic microenvironment in which a T cell
functions is likely to subvert this metabolic phenotype, thereby disrupting function.

A better understanding of how the microenvironment can affect T cell function would permit the development of metabolic
'normalising' treatments that could restore function and permit disease resolution.

However, there is currently a disconnect within the field of immunometabolism that requires high resolution, direct analyses
of T cell metabolism in order to solve. We therefore propose an approach that uses stable isotope-enriched metabolites that
are associated with immunosuppressive cancer microenvironments (e.g. 13C3-lactate) to trace their use in different T cell
populations (isolated from healthy peripheral blood), and thereby identify the precise pathway by which they are metabolised
and how this alters cytotoxic function and proliferative capacity. By inhibiting the metabolic pathway implicated either
pharmacologically, or using physiologically relevant stimuli (e.g. hypoxia), we will unequivocally link use of specific
immunomodulatory metabolites, such as lactate, succinate and citrate, with T cell function.
Multidisciplinary approach to multilayer monumental sites studies: the case of the quirinal hill in rome

The multiplicity of different historical phases can be considered one of the most singular characteristics of cultural heritage. Until today it has been clear that the scientific approach to this issue should use the developmental process as the main tool for both defining the historical phases and understanding the current state of historical heritage. Generally, it is necessary to distinguish between the diachronic and the synchronic studies, but at the same time it is mandatory to evaluate the connection between different historical layers. These opposing needs still represent a big problem that historical sciences are not always able to manage. The desirable multidisciplinary approach often produces mediocre results, while individual research generally lacks the complexity that always characterizes conservation and valorisation issues. Thus, the research project aims to discover a methodological approach that can bridge the gaps that are now often apparent between different studies. The main research goal is to define a specific digital platform for the management and consulting of the outcomes provided from the different scientific fields involved. This structure will allow to share the data collected easily, giving information about the different historical phases of a site as well as a global assessment based on its most significant transformations. The area of the ancient Temple of Serapis on the Quirinal Hill in Rome should be a good case study, that's mainly because of its complex stratigraphy. The research aims at covering the whole development period of the area by means of systematic data collection. The analysis of all different temporal phases will be fundamental for the implementation of a methodological strategy, able to involve different experts. The benefit of a web accessible digital platform able to collect all the diverse data, would be evident in the final step, when digital drawings based on new multimedia technologies will be produced.

A gas supply system criticality assessment

Heat and electricity systems are very strongly associated with fuel provision systems. Natural gas is one of the main fuels used in the heat and electricity generation process. So it is important to ensure that the infrastructure of natural gas supply remains as robust and reliable as possible. System criticality level is one of the most important indicators of reliable power supply. The simulation of a gas network was implemented by the optimization method of maximum flow. In this paper the authors present a gas supply system criticality assessment based on some results of risk analysis. The pilot calculations were performed for a closed hypothetical energy system. The results of such analysis may also be incorporated into the development of an infrastructure criticality analysis.
Search and rescue aid and surveillance using high egnss accuracy

SARA: Search and Rescue Aid using High Accuracy EGNSS

The purpose of the SARA project is to engineer and to start to commercialise a dedicated solution, based on an already existing prototype, to be used for Search and Rescue (SAR) and Surveillance purposes (primary market).
The need for such a solution comes in particular from the institutional market (but it is not limited to) requesting a technological support to manage migration flux aspects, with particular attention to crisis in the Mediterranean Sea: Europe needs to balances efforts to assist people in need with efforts to secure its borders.
On the basis of the above scenario, the industrial composition of the SARA consortium has been contacted by Italian Coast Guard two years ago in order to provide a technological contribution supporting vessels to detect people lost in the sea, especially during the hours of darkness.

According to the above request, SARA solution is conceived to build up a semi-automatic system using Earth Observation data to preliminary detect suspect pontoons’ trajectories (Surveillance) and supporting SAR operations based upon a deployable RPAS (Remotely Piloted Aircraft System) which is tightly coupled with a ship architecture through a cable (tethered flight): as soon as its function is needed, the aircraft flies from its home (a dedicated hangar on the top of the ship), and becomes a “virtual pylon” which elevates a VIS-TIR sensor (Visual Spectrum and Thermal Infrared); captured images are processed in real time by a local computer. Both RPAS and hangar are equipped with 2 high accuracy EGNSS receivers (i.e. Galileo ready) in order to provide the relative positioning between the hangar and the RPAS hovering on the target. 

On this context, EGNSS represents an essential technology ensuring autonomous operations in a reliable manner guaranteeing provision of distance and bearing from ship to survivors and the protection of the extensible cable against mechanical stress.
Preparation of Photocatalytic TiO<sub>2</sub> Filter by Chemical Surface Treatment from Ti Non-Woven Fabric

Photocatalytic titanium dioxide (TiO 2 ) filter was prepared by hydrothermal treatment in NaOH (8M) at 80°C followed by ion exchange in HCl (0.1M), and calcination at 400°C from Ti non-woven fabric (NIKKO TECHNO, Ltd.). Ti non-woven fabric is made of metallic Ti fibers. The surface area of the fabric is several times larger than flat Ti plate, so the TiO 2 filter prepared from it should have high degradation ability of organic pollutants by photocatalyst. And we thought it could be applied for the filter to purify air or water. The sample was investigated by scanning electron microscope (SEM), and energy dispersive x-ray spectrometer (EDS). The photocatalytic activity of the sample was evaluated by degradation of methylene blue (MB) solution. The change of concentration of MB solution was measured by ultraviolet visible spectrometer (UV-vis). After the hydrothermal treatment, micro network structure layer was formed on the surface of Ti. The structure was maintained after heat treatment. The elements of the layer after heat treatment were Ti and O. The sample exhibited the degradation ability of MB solution. We tried to hybridize of the TiO 2 filter and hydroxy apatite (HAp : Ca 10 (PO 4 ) 6 (OH 2 ) ) to improve degradation efficiency by adsorption ability of HAp. The hybrid material of them were prepared by soaking the TiO 2 filter into simulated body fluid (SBF) at 37.5°C for 1~7d. Then, HAp particles were formed on the surface of the TiO 2 filter. But the degradation ability was lower than non-hybrid sample.
Thermal Rate Constants for the O(3P) + CH4 → OH + CH3 Reaction: The Effects of Quantum Tunneling and Potential Energy Barrier Shape

The rate constants and kinetic isotope effects for the O(3P) + CH4 reaction have been investigated with the quantum instanton method in full dimensionality. The calculated rate constants are in good agreement with the experimental values above 400 K, below which the measured values are scattered. Compared to other theoretical approaches, the quantum instanton method predicts the largest quantum tunneling effect, so it gives the largest rate constants at low temperatures. The calculated kinetic isotope effects are always much larger than 1 and increase with decreasing temperature, due to the zero-point energy and quantum tunneling. Our calculations on different potential energy surfaces demonstrate that the potential energy barrier shape dominates the magnitude of quantum tunneling and has a great effect on the kinetic isotope effect.
New approaches to mapping the signs of violence and care in the migratory landscapes of silenced women

Currently, migration is posing a global challenge for the formation of societies and States, being a key factor of the feminisation of the phenomenon. When the migration process is undertaken under situations of vulnerability, it can be linked to structures that generate violence, exploitation, disappearance, and/or human trafficking. The routes that go from Central America to the USA by land present examples of these structures. The SIGNAL-LANDSCAPE project aims to: 1) Build a creative and transnational cartography that reflects the points of damage, as well as the care and resistance of the migratory route. 2) Design methods and tools that facilitate the processes of construction of the life story while avoiding re-victimisation. 3) Breaking the silencing to which the stories of migrant women are subjected, thus generating narrative results. 4) Produce academic knowledge, that will reach certain spaces for the design of policies and social networks.
The Researcher will carry out a multi-sited ethnography: origin (Honduras), the route (Mexico-Guatemala), and destination (USA). In these spaces, she will work with women, through local organisations, to build creative narratives that will allow the designing of: 1) the physical landscapes that reflect the damage and care that women have experienced along the route; and 2) the geographical and social landscapes of their experiences. 
The researcher has doctoral experience with Nigerian migrant women, who are often linked to human trafficking, and she has developed a methodology proposal to take into account the silencing. Furthermore, the trajectory of both supervisors in the field, the Host Centres, and the support of the two Chairs:  1) UNESCO-Gender, Wellbeing and Culture of Peace, University of Wisconsin-Madison, USA and 2) Jean Monnet-Immigration and Borders of European, University of Cádiz, Spain, will be a fundamental contribution to the proper development of the project and the positive future of the Researcher
Critical Undercooling in DNA-Mediated Nanoparticle Crystallization

The nucleation of DNA-functionalized nanoparticle superlattices is observed to exhibit a temperature hysteresis between melting (superlattice dissociation) and freezing (particle association) transitions that allows for the study of nucleation thermodynamics. Through detailed study of the assembly of these particles, which can be considered programmable atom equivalents (PAEs), we identify this hysteresis as critical undercooling-a phase transition phenomenon related to a thermodynamic barrier to nucleation. The separable nature of the DNA bonding elements and nanoparticle core enables the PAE platform to pose unique questions about the microscopic dependencies of critical undercooling and, ultimately, to control the nucleation pathway. Specifically, we find that the undercooling required to initiate nucleation increases as the nanoparticle coordination number increases (number of particles to which a single particle can bind).
Controlling inductive power transfer systems

An inductive power transfer system comprises a primary unit, having a primary coil and an electrical drive unit which applies electrical drive signals to the primary coil so as to generate an electromagnetic field. The system also comprises at least one secondary device, separable from the primary unit and having a secondary coil which couples with the field when the secondary device is in proximity to the primary unit. A control unit causes a circuit including said primary coil to operate, during a measurement period, in an undriven resonating condition. In this condition the application of the drive signals to the primary coil by the electrical drive unit is suspended so that energy stored in the circuit decays over the course of the period. A decay measurement unit takes one or more measures of such energy decay during the measurement period. In dependence upon said one or more energy decay measures, the control unit controls the electrical drive unit so as to restrict or stop inductive power transfer from the primary unit.
