In this work we report experimental tests on the performance of FTTX accesses using the mPlane measurement plane, including lab and field environments and above all we point out the role of such measurement plane in Software Defined Network architectures. For such an aim we show an experimental procedure based on a central unit (orchestrator) that automatically manages GbE links in a regional network...
Dynamically programmable data probes assist in solving verification issues of autonomous systems. Data probes can be programmed to monitor timed sequences of system data, to check system properties, and to stimulate and control autonomous systems. We present several probe programs to inspect and check various aspects of a safety invariant during a mobile robot's task execution. We report on experience...
Over the years the number of elements in a corporate network, the services and the amount of traffic have grown significantly. For this reason, it is increasingly important to analyze the traffic. Packet-based analysis is the traditional option but entails a high resources consumption. In order to palliate this, flow-based analysis arises. It usually implies to deploy a flow exporter, responsible...
Industrial software systems are often systems of systems (SoS) whose full behavior only emerges at runtime. The systems and their interactions thus need to be continuously monitored and checked during operation to determine compliance with requirements. Many requirements monitoring approaches have been proposed. However, only few of these come with tools that present and visualize monitoring results...
In recent years, privacy issues in the networking field are getting more important. In particular, there is a lively debate about how Internet Service Providers (ISPs) should collect and treat data coming from passive network measurements. This kind of information, such as flow records or HTTP logs, carries considerable knowledge from several points of view: traffic engineering, academic research,...
Over the last few decades, minimally invasive treatments have gained large interest as alternative to surgical resection. Among others, thermal treatments have broad clinical acceptance for treating a number of solid tumors. In this context, the knowledge of temperature during the treatment may be useful to improve the clinical outcomes. The aim of this work is to assess the feasibility of two multipoint...
This paper presents an application of noninvasive near-field technique for wireless structural health monitoring. The dielectric constants of Guo Biao concrete specimens were studied by means of regression modelling. The aim is to obtain the nominal values of dielectric constant of Guo Biao concrete.
A new integrated electromagnetic monitoring system has been developed to obtain a very wide frequency range 9 kHz-31 GHz. This new monitoring system has been positioned near a military USA base in Niscemi Italy to control radio emission. In this paper is presented the new electromagnetic monitoring system and it in field use.
Recently, the diffraction-limit of resolution for ultrasound imaging has been bypassed in-vivo with the localization of microbubbles [Errico et al, Nature 2015]. However, ultrasound therapy remains bound to the half-wavelength limit, imposing a compromise between the therapeutic precision and its penetration. Exploiting threshold phenomena, such as vaporization or cavitation, could provide a solution...
Tumor hypoxia has been shown to decrease the sensitivity of solid tumors to radiation. Systemic efforts to increase tumor oxygenation levels immediately prior to therapy, however, have largely proven unsuccessful. The objective of this work was to determine the utility of oxygen-filled, ultrasound sensitive microbubbles for locally delivering oxygen and sensitizing tissue to radiation in a breast...
Focused ultrasound (FUS) with circulating microbubbles creates transient and reversible permeabilization of vasculatures which provides an essential means to deliver therapeutics and imaging agents, for instance across the BBB. We have previously shown that 3D color Doppler and photoacoustic imaging can monitor BBB disruption (BBBD) in mice. Here we study how changes in NPs size, concentration and...
Large enterprises are moving towards Software Defined Network (SDN) adoption, where business-critical applications are being deployed on top of highly programmable network components and orchestrated by a single or multiple controllers using network protocols, such as OpenFlow or NetConf for communication. Just like in traditional networks, low-cost monitoring solutions need to be developed for SDN...
Aquaponics refers to the integration of hydroponics with aquaculture. The growth performance of comet goldfish against a plant of coriander, types of leafy vegetable and water plant were evaluated in recirculation of this aquaponics system towards temperature, light and fish waste effectively. The fish were feed with commercial pelleted feeds containing 30% crude protein which can provide almost all...
The consequence of road accidents that involves a motorcycle is far more fatal for the rider than the other drivers. Yet, there has not been an effective vehicle alert system that can eliminate these avoidable motorcycle accidents caused by other drivers where they fail to notice the motorcycles. One of the major flaws with the existing vehicle alert systems is that it should not treat motorcycles...
Failure analysis on static condition (static leakage and standby current level) failed device would not cost long time to find root cause, but dynamic functional failure will. Failure analysis with dynamic strategy to localize a failure point is more significant in complicated function failed IC (Integrated Circuit). This paper would present an efficient strategy to locate the defect using dynamic...
During the last decade, we witnessed a constantly increasing digitalization in the health-care domain that, while from the one hand, has increased the average life expectancy representing one of the crowning achievements of the last years, from the other hand, has introduced extra challenges due to the simultaneous increasing of the proliferation of cyber-crime and the creation of malicious applications...
Probing is a technique used for network monitoring and measurement applications, including detection of silent failures and performance analysis to verify compliance with service-level agreements. Many existing approaches to probing-path selection seek to minimize the number of probes (an NP-hard problem) or to minimize probing delay, but they fail to properly assess the network overhead imposed by...
This paper introduces the composition of continuous emission monitoring system, and the basic concepts of the artificial intelligent technologies. According to the engineering practice and the basic concepts, authors found that the sampling handing system is prone to malfunction. Furtherly, the sampling probe unit is more vulnerable, so PLC control system of the probe is detailed analyzed. In addition,...
In this paper, we propose a method to address the issue of link loss inference in uncertain networks. Although numerous loss inference methods have been proposed in recent years, most of them ignore the unstable states of networks. That is, the performances of real network environments, such as link loss rates and end-to-end routes, are constantly changing. Ignoring these uncertain factors of the...
