This paper describes the design and implementation of an automatic temperature control system. The developed temperature controller is designed to control temperature in an oven. The temperature can be controlled manually or automatically with a temperature profile imposed by the user. A bi-positional controller is implemented for temperature control. In manual mode, the user will select the set-point and the upper and lower limits. The control system will maintain the temperature within the prescribed limits. In automatic mode, the user can select a temperature profile, and the control system will impose that the temperature follows the prescribed temperature profile. © 2023 IEEE.

This paper presents a fast exponential analysis and variable projection method to reduce the number of elements in linear phased arrays. The numerical examples given in this work demonstrate a reduction of approximately 20% or 10% in the number of elements, with only a slight decrease in directivity of 0.63 dBi observed for a scan range of [−45◦, 45◦]. Compared to the combined matrix pencil and Tabu search algorithm, the proposed technique converges in fewer iterations and exhibits ≈ 5 dB reduction in maximum side lobe level. © 2002-2011 IEEE All rights reserved.

Underwater target localization has always been a challenging and important research topic in underwater acoustic sensing, especially when the underwater target is moving. This paper uses three pulse signals for system design: continuous wave, linear frequency modulated signal and rational orthogonal wavelet signal. We use a geometric underwater channel model to generate a database of underwater signals with specified geometric parameters of ocean environments to simulate the ocean. The received pulses signal are converted into feature maps as the classifier's input. In this paper, Short-time Fourier transform, Mel-frequency cepstral coefficient, Gammatone frequency cepstral coefficient and Perceptual linear prediction coefficient are applied to construct different feature maps. The classifier uses a lightweight CNN model. Experiments demonstrate the superiority of wavelet pulse signals in underwater target localization. The multipath effect will also contribute to underwater acoustic sensing. © 2023 IEEE.

We address the problem of handwritten word retrieval in documents belonging to small collections of historical interest. Word retrieval consists of finding the images of a given query word, and one of the techniques commonly used to solve this problem is Keyword Spotting (KWS), which promises to retrieve images of words without requiring explicit handwriting recognition. KWS systems, however, are limited by the problem of so called out-of-vocabulary (OOV) words, i.e. words not included in the training set, that cannot be retrieved. To overcome this limitation, we propose a KWS system that focuses the search on character sequences, referred to as N-grams, instead of whole words, thus aiming to make OOV words searchable. The system is based on a Siamese Network that searches for all the N-gram images of the training set that corresponds to the N-gram of the query word and outputs a ranked list of possible images of the searched word extracted from the collection. The results show that the system is able to retrieve words indiscriminately from the set of In-Vocabulary and Out-Of-Vocabulary words, showing similar performance in both cases, suggesting that focusing the search on N-grams may provide a valid solution to the OOV word search problem. © 2022 Copyright for this paper by its authors.

European Signal Processing Conference (EUSIPCO)

作者： Yuhao Liu Chen Cui Daniel Waxman Kurt Butler Petar M. Djurić Department of Applied Mathematics and Statistics Department of Electrical and Computer Engineering Stony Brook University NY

One of the most important problems in science is understanding causation. This is particularly challenging when one has access to observational data only and is further compounded in the presence of latent confounders. In this paper, we propose a method for detecting confounders in multivariate time series using a recently introduced concept referred to as differential causal effect (DCE). The solution is based on feature-based Gaussian processes that are used for estimating both, the DCE of the observed time series and the latent confounders. We demonstrate the performance of the proposed method with several examples. They show that the proposed approach can detect confounders and can accurately estimate causal strengths.
