With restrict of market and society policy, some manufacturing firms' profit becomes less and less especially in the hydraulic fracturing field. This paper proposes a hydraulic fracturing product service system (HF-PSS) as a new firm strategy to shift from product-centered paradigm to service-centered paradigm for maximizing profit and totally satisfying customer needs to tackle this dilemma. Considering...
Wearable devices have emerging in last years with diverse applications for provide user convenience. Health care, sports, safety are some examples of areas in which wearable devices have been applied. This paper describes an overview about wearable architectures found in the literature and presents a novel wearable for monitoring ecological environments. The wearable is composed of a Head-UP Display...
The increasing complexity of modern digital circuits has exacerbated the challenge of verifying the functionality of these systems. To further compound the issue, shrinking time-to-market constraints place increased pressure on attaining correct devices in short amounts of time. As a result, more and more of the burden of validation has shifted to the post-silicon stage, when the first silicon prototypes...
Daily management of neurodegenerative diseases by electrical neuromodulation techniques requires an integrated health care system for the continuous assistance to the patient. In this scenario, a direct bi-directional exchange of information between the patient's electronic health record (EHR) and patient's personal mobile health apps (mHealth) can boost the active contribution of patients and caregivers...
The paper focuses on the problem of interconnecting different cloud providers with the aim of offering enhanced services. The Intercloud scenario is based on the key concept that any cloud by itself does not have infinite natural resources or stable geographic location. The paper presents a distributed architecture for interconnecting existing cloud services, from different cloud providers (Firebase,...
The global feature extractor (gFEX) is a component of the Level-1 Calorimeter trigger Phase-I upgrade for the ATLAS experiment. It is intended to identify patterns of energy associated with the hadronic decays of high momentum Higgs, W, & Z bosons, top quarks, and exotic particles in real time at the LHC crossing rate. The single processor board will be packaged in an Advanced Telecommunications...
The Large Hadron Collider has envisaged a series of upgrades towards a High Luminosity LHC delivering five times the LHC nominal instantaneous luminosity. The ATLAS Phase II Upgrade will accommodate the detector and data acquisition system for the HL-LHC. In particular, the Tile Hadronic Calorimeter will completely replace front-end and back-end electronics using a new read-out architecture. The digitized...
In this paper we address the problem of massive event trace sizes, one of the most urgent challenges in the performance analysis of large-scale parallel applications. Reducing trace sizes during the application runtime decreases application slow down, eliminates measurement bias, and cuts down stress on the underlying file system. Previous approaches use static filters to decrease trace size, which...
For server and network administrators, it is a challenge to keep an overview of their systems to detect potential intrusions and security risks in real-time as well as in retrospect. Most security tools leverage our inherent ability for pattern detection by visualizing different types of security data. Several studies suggest that complementing visualization with sonification (the presentation of...
This article shows the development and implementation of a device which is capable of monitoring peripheral oxygen saturation in the blood (SpO2) and heart rate of a person in beats per minute (bpm). This can be achieved by conditioning the signal obtained from the sensor Nellcor DS-100A, including a step of converting the current signal to voltage, a step of noise Altering in the signal and finally...
This paper presents implementation of a reactive base station selection scheme for millimeter-wave (mmWave) communications. In mmWave communications, the frame loss rate increases and the throughput sharply decreases when a pedestrian blocks a line-of-sight (LOS) path. To alleviate this human blockage problem, base stations can be selected so as to maintain LOS paths on the basis of communication...
The energy consumption had grown deeply in the entire world. In Brazil, although the economic growth in the last years had been underwhelming, the growth rate of the energy consumption was impressively high. Recently, at the beginning of the year 2015, meaningful adjusts had been done at the energy tax. Especially on the state of Santa Catarina the National Agency of Electrical Energy of Brazil (ANEEL)...
Insufficient data visualization in current social media tools is hampering opportunities to make effective meaning and take decisive action from social data. This paper presents the technical architecture of a prototype tool for Social Business Intelligence (SBI) under development. Adopting an Action Design Research approach, the goal of the 'Social Newsroom' is to provide practitioners with user...
Nowadays, Unmanned Aerial Vehicles (UAVs) platform are widely employed in a broad range of applications: from environmental monitoring and precise agriculture to humanitarian localization and rescue and prevention of events such as floods, fires, landslides. On the other hand, Global Navigation Satellite System Reflectometry (GNSS-R) is an emerging technique which allows to monitor Earths surface...
In order to enable and support lifelong learning, learners need to be aware of their learning processes. This work proposes a framework for supporting Self-regulation in Seamless Learning scenarios. The framework is based on the Endsley's Model for Situation Awareness. Moreover, the framework is contextualised to a specific class of learning scenarios in order to better explain its potentiality. In...
Thales Italia has developed an advanced prototype of a CBRNe (Chemical, Biological, Radiological, Nuclear and explosives) Threat Detection & Monitoring System that features beacons embedding innovative smart sensors, integrating CMOS chip microsensors and exploiting Wideband Electrical Impedance Spectroscopy technology. Each beacon is in the form of lab-on-a-chip already inclusive of electronic...
This paper designs a wireless sensor mote platform, which harvests the micro environmental energy as its power source, and uses a fidelity-based energy policy to manage the working and recharging process of the sensor mote. Additionally a data collection and control framework is involved in this paper for practical account. A proof-of-concept prototype powered by the micro corrosion energy from the...
Industry and government organisations across the world increasingly use social media for Customer Relationship Management (CRM) activities that include communicating with customers about their services/products and distilling customer opinions for assessing their effectiveness. In this paper, we explore the exploitation of social media for CRM, and describe the development and functionality of VIZIE...
For a variety of economic and practical reasons, security patches often cannot be deployed immediately after a patch’s release. To mitigate attacks against unpatched software, we present the design and evaluation of a Moving Target tech- nique that uses a form of software diversity called multi-variant execution. Our technique decomposes the software’s behavior into its low-level system calls and...
In this article, we present some preliminary work on integrating an artificial curiosity mechanism in PROPRE, a generic and modular neural architecture, to obtain online, open-ended and active learning of a sensory-motor space, where large areas can be unlearnable. PROPRE consists of the combination of the projection of the input motor flow, using a self-organizing map, with the regression of the...
