Question (Q&A-128 IEEE Global Communications Conference, GLOBECOM 2. Proceedings. View/Download from: UTS OPUS or Publisher's site& copy; 2. IEEE. A critical task in forced oscillation technique (FOT), a promising lung function test, is to remove respiratory artefacts. Manual removal by specialists is widely used but time- consuming and subjective. Most existing automated techniques have involved simple thresholding methods in an unsupervised manner. ![]() Breath cycles can be classified by a binary classification model (classes: artefactual and accepted). While attempting to use off- the- shelf sorting algorithms (e. This may result from the dependence of samples as found in physiological studies of the lung function that challenges the learning process. Specifically, statistics of breaths that we recorded may change from one to another patient and even within the same recording of a patient. We introduce an additional feature engineering step that is an intermediate module to decorrelate samples, called feature learning (using Wilcoxon signed rank tests). To that end, we collected FOT recordings from various groups of patients (paediatric and adult including healthy and asthmatics). Artefacts in this work were recorded naturally and processed in a complete- breath approach. Performance metrics include evaluations on preservation of . Our experiment found that our feature engineering steps significantly improve the artefact removal performance of all implemented classifiers especially with feature inputs selected by mutual information criterion.

Asia Pacific Symposium on Intelligent and Evolutionary Systems, Springer, Canberra, Australia. View/Download from: Publisher's site. Wireless Sensor Networks (WSNs) have been recently used for various applications. Due to the distributed and (often) unattended nature of the nodes after deployment, the lack of energy and the interruptive process in each sensor are the two major problems of WSN systems. Hence, designing a protocol which not only improves system performance but also lowers sensors' energy consumption so as to maximize the network lifetime is very much desirable. The network lifetime maximization problem was known to be NP- Hard. This paper addresses the Minimum Energy- Multicasting (MEM) problem in Duty- Cycle Wireless Sensor Networks (DC- WSNs) in which sensors cyclically switch between on/off (wake/sleep) modes. To that end, we propose a local search algorithm and compare its performance with the best algorithm so far called GS- MEM over the four datasets designated for the MEM problem. The experimental results show that our proposed algorithm significantly outperforms GS- MEM in terms of energy cost. Vo, K., Nguyen, D., Hoang, H. K. 2. 01. 7, 'Dynamic Stopping Using e.

S., Dutkiewicz, E. Joint source- channel optimization of vector quantization with polar codes', IEEE Vehicular Technology Conference. View/Download from: Publisher's site& copy; 2. IEEE. Joint application of polar channel coding combined with vector quantization lossy source coding is considered in this paper. The existing index assignment schemes in the literature cannot be used with polar codes due to their unique crossover probabilities. We elaborate on this problem and locally optimize index assignments. In addition, we propose an algorithm that jointly optimizes the number of quantization levels and the rate of the polar code in order to achieve minimum end- to- end distortion. It finds the optimal tradeoff between the distortion caused by channel errors and the quantization distortion. We also derive estimates for the crossover probabilities of the polar code which are required in the analysis. Simulation results confirm the effectiveness of the proposed algorithms and the accuracy of the crossover probabilities. Huiyang Wang, Eryk Dutkiewicz, Gengfa Fang & Markus Dominik Mueck 2. A Fair Spectrum Sharing Framework Based on Topological Sort and Max Weight for Femtocells', 2. Australian Communications Theory Workshop, Aus. CTW 2. 01. 6, Australian Communications Theory Workshop, IEEE, Monash University, Australia. View/Download from: Publisher's site. Femto base stations will be widely deployed in 5. G times for compensating poor cellular coverage for use in residential or small business environments. In this paper, we propose a spectrum sharing framework, where a cluster of femtocells are under the control of a centralized local manager. The framework assumes that each femto base station has the sniffing ability that can detect its neighbor femtocells and the controller can then have complete knowledge of local interference constraints. Unlike distributed Wi. Fi that runs on unlicensed band, the femtocell owned by a carrier runs on licensed band and the carrier prefers a centralized system to a distributed one. Therefore, a fair spectrum sharing policy on the licensed band is more important among carriers to break the monopoly and inefficient spectrum allocation. Considering the spectrum can be spatial reused, an interference graph is adopted to avoid the interference between femtocells of all the carriers. We test the framework not only by comparing the average number of channels per user can get but also the variance to guarantee the fairness. In this framework, the scheme combining topological sort and maximum traffic load of femtocell contributes to keep a better balance on the average number of channels and variance. Bautista, M.

Sampling of band- limited signals with nonuniform sampling- time and bit- depth', 2. IEEE Global Communications Conference, GLOBECOM 2. IEEE Global Communications Conference (GLOBECOM), IEEE, San Diego, USA. View/Download from: Publisher's site& copy; 2. IEEE. To reproduce a band- limited continuous- time signal with optimal fidelity, usually it is sampled at the Nyquist sampling rate and then the sample values are quantized. In nonuniform sampling, the total number of samples are reduced in expense of adding some reconstruction complexity and assuming prior information about the signal. In this paper we propose nonuniform sampling- time with nonuniform bit resolution per sample (bit- depth) to reduce the total required bit budget (i. This idea is based on the fact that the maximum local variation of band- limited signals is bounded in a given time horizon. Therefore, it is not necessary to allocate a fixed bit- depth proportional to the signal's dynamic range to each sample. Instead, we try to allocate adaptively only the needed number of bits to represent the next sample considering the physical characteristics of the signal. Both sampling and reconstruction entities can generate the next sampling- times and bit- depths locally by observing the current and previous samples only. We propose different techniques in our generalized sampling framework that share a common sampling architecture. Here we only consider ECG signals for evaluation purpose. Based on the simulation results, the total number of required bits to reconstruct the signal with negligible distortion can be reduced up to 8. He, Y., Dutkiewicz, E., Fang, G. SNR threshold for distributed antenna systems in Cloud Radio Access Networks', 2. IEEE 8. 2nd Vehicular Technology Conference, VTC Fall 2. Proceedings. View/Download from: UTS OPUS or Publisher's site& copy; 2. IEEE. A distributed antenna system (DAS) architecture is a key enabler for Cloud Radio Access Networks (CRAN) where geographically separated base stations are connected to a centralized processing and decision making unit. Many schemes have been proposed to leverage Fractional Frequency Reuse (FFR) and co- ordinated joint transmission between base stations to improve cell- edge performance for static network deployments. In this paper, we investigate dynamic decision making that whether co- ordinated joint transmission should be selected in the downlink of a FFR- aided DAS. We derive the transmitting Signal- to- Noise- Ratio (SNR) threshold that co- ordinated joint transmission can provide better performance if the transmitting SNR is below this threshold. We simulated a three- cell cluster layout with FFR and the numerical results agree with our analytical results. We show that the transmitting SNR threshold is critical in the FFR- aided DAS analysis and can be used as a guide in the CRAN network planning and the evaluation of DAS performance.
