This paper devises a dynamic queueing model for the airport check-in process. The airport scheduling system is highly dynamic, for it is inherently highly dimensional and takes input from a various of involved parties, i.e., passengers, airport staff, airport infrastructure, airline companies and etc. The proposed model presents a top-down focus to guarantee a reliable, punctual and efficient check-in scheduling scheme and is later generalized from bottom-up to be applicable for other processes. In our work, we design a flow logic and derive the framework analytically with MATLAB. Then the simulation of service time and arrival distribution are provided. In the Experiment, the real data collected from Hamburg International Airport was fed into the model and achieved satisfying results. Both analytically and experimentally, we prove that our model is capable of solving dynamic queueing problems.

Image registration is a fundamental medical image analysis task, and a wide variety of approaches have been proposed. However, only a few studies have comprehensively compared medical image registration approaches on a wide range of clinically relevant tasks. This limits the development of registration methods, the adoption of research advances into practice, and a fair benchmark across competing approaches. The Learn2Reg challenge addresses these limitations by providing a multi-task medical image registration data set for comprehensive characterisation of deformable registration algorithms. A continuous evaluation will be possible at https://***. Learn2Reg covers a wide range of anatomies (brain, abdomen, and thorax), modalities (ultrasound, CT, MR), availability of annotations, as well as intra- and inter-patient registration evaluation. We established an easily accessible framework for training and validation of 3D registration methods, which enabled the compilation of results of over 65 individual method submissions from more than 20 unique teams. We used a complementary set of metrics, including robustness, accuracy, plausibility, and runtime, enabling unique insight into the current state-of-the-art of medical image registration. This paper describes datasets, tasks, evaluation methods and results of the challenge, as well as results of further analysis of transferability to new datasets, the importance of label supervision, and resulting bias. While no single approach worked best across all tasks, many methodological aspects could be identified that push the performance of medical image registration to new state-of-the-art performance. Furthermore, we demystified the common belief that conventional registration methods have to be much slower than deep-learning-based methods. © 2021, CC BY.

This paper presents a serious game-based system for dance notation training named LabanDance. The system tracks the full body motion via Microsoft Kinect of the user while performing the movement according to the dancing score. The system provides two training modes which a practice mode and an examination mode. The practice mode is designed for users with less knowledge in the notation where movement of a virtual inst.uctor is displayed according to the score for a user to follow. The second mode is the examination mode where users must perform the body movement according to the displayed Labanotation symbols within the provided time frame. The experiment showed that users without knowledge of Labanotation can enjoy the game while learning the fundamental of the Labanotation. © 2017 IEEE.

The article proposes the structure of an intelligent software platform for managing complex risks. It is proposed to divide the platform into a global and local part (end-point software) that provides not only the management of complex risks on the scale of a single system (enterprise, organization) but also the collection, accumulation, synthesis and dissemination of methods and models of integrated risk management that are best practices that have proven effective on practice. Within the local part, the platform provides the ability to build complexes of hybrid intelligent models by a risk management specialist without the participation of a programmer. Examples of using the proposed solution or its parts in projects aimed at risk management are considered. © 2018 IEEE.

Hotspots occur frequently in 3D multi-core processors (3D-MCPs), and they may adversely impact both the reliability and lifetime of a system. We present a new thermally constrained task scheduler based on a thermal-pattern-aware voltage assignment (TPAVA) to reduce hotspots in and optimize the performance of 3D-MCPs. By analyzing temperature profiles of different voltage assignments, TPAVA pre-emptively assigns different initial operating-voltage levels to cores for reducing temperature increase in 3D-MCPs. The proposed task scheduler consists of an on-line allocation strategy and a new voltage-scaling strategy. In particular, the proposed on-line allocation strategy uses the temperature-variation rates of the cores and takes into two important thermal behaviors of 3D-MCPs that can effectively minimize occurrences of hotspots in both thermally homogeneous and heterogeneous 3D-MCPs. Furthermore, a new vertical-grouping voltage scaling (VGVS) strategy that considers thermal correlation in 3D-MCPs is used to handle thermal emergencies. Experimental results indicate that, when compared to a previous online thermally constrained task scheduler, the proposed task scheduler can reduce hotspot occurrences by approximately 66% (71%) and improve throughput by approximately 8% (2%) in thermally homogeneous (heterogeneous) 3D-MCPs. These results indicate that the proposed task scheduler is an effective technique for suppressing hotspot occurrences and optimizing throughput for 3D-MCPs subject to thermal constraints.

Quantum computing has seen tremendous progress in the past years. Due to the implementation complexity and cost, the future path of quantum computation is strongly believed to delegate computational tasks to powerful quantum servers on cloud. Universal blind quantum computing (UBQC) provides the protocol for the secure delegation of arbitrary quantum computations, and it has received significant attention. However, a great challenge in UBQC is how to transmit quantum state over long distance securely and reliably. Here, we solve this challenge by proposing a resource-efficient remote blind qubit preparation (RBQP) protocol with weak coherent pulses for the client to produce, using a compact and low-cost laser. We experimentally verify a key step of RBQP - quantum non-demolition measurement - in the field test over 100-km fiber. Our experiment uses a quantum teleportation setup in telecom wavelength and generates 1000 secure qubits with an average fidelity of (86.9 ± 1.5)%, which exceeds the quantum no-cloning fidelity of equatorial qubit states. The results prove the feasibility of UBQC over long distances, and thus serving as a key milestone towards secure cloud quantum computing. Copyright © 2019, The Authors. All rights reserved.

Low-overhead coordination in sub-28 millimeter-wave networks

In this paper, we present some contributions from our recent investigation. We address the open issue of interference coordination for sub-28 GHz millimeter-wave communication, by proposing fast-converging coordination algorithms, for dense multi-user multi-cell networks. We propose to optimize a lower bound on the network sum-rate, after investigating its tightness. The bound in question results in distributed optimization, requiring local information at each base station and user. We derive the optimal solution to the transmit and receive filter updates, that we dub non-homogeneous waterfilling, and show its convergence to a stationary point of the bound. We also underline a built-in mechanism to turn-off data streams with low SINR, and allocate power to high-SNR streams. This "stream control" is a at the root of the fast-converging nature of the algorithm. Our numerical result conclude that low-overhead coordination offers large gains, for dense sub-28 GHz systems. These findings bear direct relevance to the ongoing discussions around 5G New Radio. Copyright © 2018, The Authors. All rights reserved.

In both theoretical analysis and practical use for an anti-dictionary coding algorithm, an important problem is how to encode an antidictionary of an input source. This paper presents a proposal for a com-pact tree representation of an antidictionary built from a circular string for an input source. We use a technique for encoding a tree in the compression via substring enumeration to encode a tree representation of the antidic-tionary. Moreover, we propose a new two-pass universal antidictionary coding algorithm by means of the proposal tree representation. We prove that the proposed algorithm is asymptotic optimal for a stationary ergodic source. Copyright © 2017 The inst.tute of Electronics, Information and Communication Engineers.

We address the problem of inferring an undirected graph from nodal observations, which are modeled as non-stationary graph signals generated by local diffusion dynamics on the unknown network. We propose a two-step approach where we first estimate the unknown diffusion (graph) filter, from which we recover the eigenvectors of the so-called graph-shift operator (a matrix representation of the graph). We then estimate the eigenvalues by imposing desirable properties on the graph to be recovered. To carry out the initial system identification step, we assume that second-order statistics of the inputs are available. While such quadratic filter identification problem boils down to a non-convex fourth order polynomial minimization, we propose a semidefinite relaxation with provable performance guarantees. Finally, numerical tests illustrate the use of the proposed algorithm to unveil urban mobility patterns.

Generation of wireless network from past to present deals with many fatal problems such as - spectrum scarcity, lower data rates, power deficiency, synchronization, unfavorable diversity, inferior QoS, and Interference. Many of the above problems are resolved in some manner using a better modulation and multiplexing technique using Orthogonal Frequency Division Multiplexing (OFDM), however, it still interlocks with Interference hindrance. In the paper, we surveyed all about OFDM interference's - Inter Symbol Interference (ISI), Inter Carrier Interference (ICI) and Co-Channel Interference (CCI) which greatly inhibits the Bit Error Rate (BER) of OFDM. Moreover, this paper also reviews some of the good research on interference mitigation techniques. We also surveyed the work on wavelet transform which is quite effective in OFDM system compare to conventional Fourier transform. Channel coding is a measurable parameter which is a mere technique in reducing the CCI effect from the wireless system, for that we elaborate Space Time Block Code-OFDM (STBC-OFDM) to reduce ICI and CCI.
