Nowadays, one standard therapy for advanced heart failure is the implantation of left ventricular assist devices (LVAD). The LVAD is a mechanical pump, which supports the heart to pump blood to the rest of the body. However, there are serious complications including pump thrombosis. Pump thrombosis is a formation of blood clot inside the LVAD pump, which can result in pump stop and worst case leads...
The Compressed Sensing (CS) framework is heavily utilized to reduce data rate in hardware restricted scenarios by exploiting the intrinsic sparsity of the transmitted data. Considering multiple sensors at the same time, one variation of the Multi Channel (MC) framework takes several measurements at one time instant and then uses CS in the spatial domain to compress the data. This paper provides a...
Radiated emission tests are generally performed in either free space, reflection-free environments, such as an open area test site or semi- or full-anechoic chambers, or in reverberation chambers. This paper describes measurements in semireflecting environments such as an office, a workshop of a large industrial apparatus or installation. The objective is to develop test methods and associated correction...
Particle Swarm Optimization (PSO) is a powerful algorithm that can search a solution for a function which contains a large number of peaks and valleys. However, PSO might encounter a difficulty when the function gets more complex or the number of attributes (dimensions) grows larger. This paper proposes a modification of PSO by using the incremental attribute strategy along with the centroid of particle's...
The current status of ITS deployment around Europe is characterized by lack of Standards for ITS implementation at EU level, limited cooperation among the various related IT Stakeholders and more importantly lack of wide awareness of the results and outcomes deriving from numerous and significant investments in ITS throughout Europe. This knowledge fragmentation can be reduced through the development...
In this paper, we investigate a largely extended version of classical MAB problem, called networked combinatorial bandit problems. In particular, we consider the setting of a decision maker over a networked bandits as follows: each time a combinatorial strategy, e.g., a group of arms, ischosen, and the decision maker receives a rewardresulting from her strategy and also receives a side bonusresulting...
various researchers and practitioners have identified a range of problems and deficiencies with existing change-related frameworks, while each framework can include unique valuable elements in its people/process/technology aspects and theoretical foundations. In such a setting, we have adopted a holistic approach through examining an armada of existing frameworks and methodologies. Several decades...
This paper presents an algorithm that achieves high quality video compression with low memory bandwidth of reference frame data and latency due to computation in motion estimation for screen content. Efficiency is attained by content-adaptive placement of the search windows within the reference frames. In our scheme, the center location of the search window is decided by k most prominent motion vectors...
In this paper, the problem of queue in convenient stores is considered. We propose a low cost automatic queue length monitoring system by using an Internet-of-Things (IoT) platform. This system can detect the length of queue and the number of people that enqueue and leave the queue. If the length of queue is critical, the system will alert to staff via LINE Notify. Experimental results indicate that...
To judge the contents of a box, we do not necessarily have to open it. By shaking a box we can make an estimate of its contents based on haptic and auditory information. Not much is known about the perception of properties of objects that are inside a box. In this study we investigated how accurately participants can judge the number of wooden spheres inside a small handheld box by shaking the box...
This workshop will explore integration of Web archiving and digital libraries, so the complete life cycle involved is covered: creation/authoring, uploading/publishing in the Web (2.0), (focused) crawling, indexing, exploration (searching, browsing), archiving (of events), etc. It will include particular coverage of current topics of interest, like: big data, mobile web archiving, and systems (e.g...
Network providers now want to enable users to define their own flow priorities, and commercial devices already implement this ability. However, it has been shown that directly applying arbitrary user-defined priorities can fundamentally destabilize a network. In this paper, we show that it is possible to apply user-defined priorities while keeping the network stable. We introduce U-BP, a scalable...
We consider the scenario where a cloud service provider (CSP) operates multiple geo-distributed datacenters to provide Internet-scale service. Our objective is to minimize the total electricity and bandwidth cost by jointly optimizing electricity procurement from wholesale markets and geographical load balancing (GLB), i.e., dynamically routing workloads to locations with cheaper electricity. Under...
For the model of three-phase four-wire power supply system in an unbalanced non-sinusoidal periodic mode, which takes into account the energy losses in the active resistance of a power cable, the physical meaning of the presented formula for apparent power definition is analyzed. The conditions of its equivalence with the formulas given in the IEEE and European standards are defined. Based on the...
The paper encourages the development of energy-saving technologies and the improvement of environmental safety of road transport. Expected results: the joint educational program for master's degree of project related speciality has been created and is ready for the implementation; curricular/syllabi, training courses, methodical and teaching materials have been developed; retraining and advanced training...
In this paper we present some preliminary experimental results related to searching correlations between users' psychological traits and the properties of their social network graph. We explore simple clustering techniques on standard available data extracted from mainstream social media platforms. Our experiments on approximately 1000 users show that we are capable of identifying 9 groups of users...
The ratio of the tympanogram width (gradient) at a frequency of 226 Hz, which is standard for impedancemetry of the human middle ear, flexibility, the area of the eardrum and the angle that characterizes its obliquity, was theoretically and experimentally confirmed. It is determined that the magnitude of the outer ear canal volume coincides with an equivalent volume of the women's and children's middle...
The strain imposed by the bandwidth demands of multimedia applications on wired and wireless networks calls for efficient novel solutions to the problem of network resource allocation, to avoid significant packet losses. In this letter, we focus on a large variety of MPEG-4, H.264 and H.265-encoded video traces. We use the metaheuristic technique of Simulated Annealing to predict the size of B-frames,...

The system solves the problem of defects recognition and classification, and enhances performance testing in comparison with traditional instruments.
Porous wicks are employed in two-phase thermal management devices such as heat pipes and vapor chambers. The capillary forces generated across the liquid-vapor interface in these wick structures causes circulation of working fluid. The liquid flow in such wicks are typically characterized by low Bond (Bo = pgL2/σ), Capillary (Ca = μV/σ) and Reynolds (Re = pvL/μ) numbers [Bo ∼ O(10−7), Ca ∼ O(10−5),...
