In this paper, we present a Building-Level fUlly-labeled dataset for Electricity Disaggregation (BLUED). The dataset consists of voltage and current measurements for a single-family residence in the United States, sampled at 12 kHz for a whole week. Every state transition of each appliance in the home during this time was labeled and time-stamped, providing the necessary ground truth for the evaluation of event-based algorithms. With this dataset, we aim to motivate algorithm development and testing. The paper describes the hardware and software configuration, as well as the dataset’s benefits and limitations.

There are a small number of commercially available systems that implement NILM, albeit marketed for utilities as a tool for performing load research. As a proof of concept, and in order to obtain preliminary data that would help us evaluate the feasibility of using NILM to support electricity audits in a residential building, we decided to focus our attention on one of the top residential loads: the refrigerator. We installed a NILM prototype system in an apartment building, and a plug-level power meter was used to accurately track the individual consumption of this appliance.

abstract = “We present a mobile visual clothing search system whereby a smart phone user can either choose a social networking photo or take a new photo of a person wearing clothing of interest and search for similar clothing in a retail database. From the query image, the person is detected, clothing is segmented, and clothing features are extracted and quantized. The information is sent from the phone client to a server, where the feature vector of the query image is used to retrieve similar clothing products from online databases. The phone’s GPS location is used to re-rank results by retail store location. State of the art work focuses primarily on the recognition of a diverse range of clothing offline and pays little attention to practical applications. Evaluated on a challenging dataset, the system is relatively fast and achieves promising results.” abstract_short = “A mobile visual clothing search system is presented whereby a smart phone user can either choose a social networking image or capture a new photo of a person wearing clothing of interest and search for similar clothing in a large cloud-based ecommerce database.

Berges”,“H. Young Noh”] publication_types = [“1”] publication_short = “” abstract = “In spite of their many advantages, real-world application of guided-waves for structural health monitoring (SHM) of pipelines is still quite limited. The challenges can be discussed under three headings: (1) Multiple modes, (2) Multipath reflections, and (3) Sensitivity to environmental and operational conditions (EOCs). These challenges are reviewed in the authors’ previous work. This paper is part of a study whose objective is to overcome these challenges for damage diagnosis of pipes, while addressing the limitations of the current approaches. That is, develop methods that simplify signal while retaining damage information, perform well as EOCs vary, and minimize the use of transducers. In this paper, a supervised method is proposed to extract a sparse subset of the ultrasonic guided-wave signals that contain optimal damage information for detection purposes. That is, a discriminant vector is calculated so that the projections of undamaged and damaged pipes on this vector is separated. In the training stage, data is recorded from intact pipe, and from a pipe with an artificial structural abnormality (to simulate any variation from intact condition). During the monitoring stage, test signals are projected on the discriminant vector, and these projections are used as damage-sensitive features for detection purposes. Being a supervised method, factors such as EOC variations, and difference in the characteristics of the structural abnormality in training and test data, may affect the detection performance. This paper reports the experiments investigating the extent to which the differences in damage size and damage location, as well as temperatures, can influence the discriminatory power of the extracted damage-sensitive features. The results suggest that, for practical ranges of monitoring and damage sizes of interest, the proposed method has low sensitivity to such training factors. High detection performances are obtained for temperature differences up to 14°C. The findings reported in this paper suggest that although the proposed method is a supervised approach, labeling of the training data does not require prior knowledge about the damage characteristics (e.g., size, location). Moreover, the potential of the proposed method for online monitoring is illustrated, for wide range of temperature variations and different damage scenarios.” image_preview = “” selected = false projects = [] url_custom = [{name = “DOI”, url = “http://dx.doi.org/10.1117/12.2084439"}] math = true highlight = true [header] image = “” caption = “” +++

Young Noh”] publication_types = [“1”] publication_short = “” abstract = “Ultrasonic guided-waves propagating in pipes with varying environmental and operational conditions (EOCs) are usually the results of complex superposition of multiple modes travelling in multiple paths. Among all of the components forming a complex guided-wave signal, the arrivals scattered by damage (so called scatter signal) are of importance for damage diagnosis purposes. This paper evaluates the potentials of nonlinear decomposition methods for extracting the scatter signal from a multi-modal signal recorded from a pipe under varying temperatures. Current approaches for extracting scatter signal can be categorized as (A) baseline subtraction methods, and (B) linear decomposition methods. In this paper, we first illustrate, experimentally, the challenges for applying these methods on multi-modal signals at varying temperatures. To better analyze the experimental results, the effects of temperature on multi-modal signals are simulated. The simulation results show that different wave modes may have significantly different sensitivities to temperature variations. This brings about challenges such as shape distortion and nonlinear relations between the signals recorded at different temperatures, which prevent the aforementioned methods to be extensible to wide range of temperatures. In this paper, we examine the potential of a nonlinear decomposition method, namely nonlinear principal component analysis (NLPCA), for removing the nonlinear relation between the components of a multi-modal guided-wave signal, and thus, extracting the scatter signal. Ultrasonic pitch-catch measurements from an aluminum pipe segment in a thermally controlled laboratory are used to evaluate the detection performance of the damage-sensitive features extracted by the proposed approach. It is observed that NLPCA can successfully remove nonlinear relations between the signal bases, hence extract scatter signal, for temperature variations up to 10℃, with detection accuracies above 99%.” image_preview = “” selected = false projects = [] url_custom = [{name = “DOI”, url = “http://dx.doi.org/10.1117/12.2084436"}] math = true highlight = true [header] image = “” caption = “” +++

The objective of this paper is to develop damage detection methods that simplify guided-wave signals while retaining damage information and have low sensitivity to EOC variations. A supervised method is proposed for damage detection. The detection performance is maximized, by imposing a sparsity constraint on the signals. This paper reports a diverse set of laboratory and field experiments validating the extent to which EOC variations, as well as damage characteristics can influence the discriminatory power of the damage-sensitive features. The laboratory setup includes an aluminum pipe with temperature varying between 24 and 38 ° C. The method is further validated using an operational hot water supply piping system of different size and configuration than the one used in the laboratory, which operates under noisy environment, with constantly varying flow rate, temperature, and inner pressure. Moreover, the proposed method is used to detect occurrence of consecutive actual damages, namely, a crack and a mass loss as small as 10% and 8% of the wall thickness, respectively. The validation results suggest that a simple binary-labeled training data (i.e., undamaged/damaged), obtained under a limited range of EOCs, are sufficient for the proposed method. That is, the detection method does not require prior knowledge about the characteristics of the damage (e.g., size, type, and location), and/or a training dataset that is obtained from a wide range of EOCs.

Rowe”] publication_types = [“2”] publication = “Advanced Engineering Informatics“ publication_short = “” abstract = “Non-Intrusive Load Monitoring (NILM) has been studied for a few decades now as a method of disaggregating information about appliance level power consumption in a building from aggregate measurements of voltage and/or current obtained at a centralized location in the electrical system. When such information is provided to the electricity consumer as feedback, they can then take the necessary steps to modify their behavior and conserve electricity. Research has shown potential for savings of up to 20% through this kind of feedback. The training phase required to allow the algorithms to recognize appliances in the home at the beginning of a NILM setup is a big hindrance to wide adoption of the technique. One of the recent advances in this research area includes the addition of an Electro-Magnetic Field (EMF) sensor that measures the electric and magnetic field nearby an appliance to detect its operational state. This information, when coupled with the aggregate power consumption data for the home, can help to train a NILM system, which is a significant step forward in automating the training phase. This paper explores the theory behind the operation of the EMF sensor and discusses the feasibility of automating the training and classification process using these devices. A case study is presented, where magnetic field measurements of eight appliances are analyzed to determine the viability of using these signals alone to determine the type of appliance that the EMF sensor has been placed next to. Various dimensionality reduction techniques are applied to the collected data, and the resulting feature vectors are used to train a variety of common machine learning classifiers. A vector subspace obtained using Independent Component Analysis (ICA), along with a k-NN classifier, was found to perform best among the different alternatives explored. Possible reasons behind the findings are discussed and areas for further exploration are proposed.” image_preview = “” selected = false projects = [] url_custom = [{name = “DOI”, url = “http://dx.doi.org/10.1016/j.aei.2013.03.004"}] math = true highlight = true [header] image = “” caption = “” +++

Although a baseline, which is the estimation of what the load would have been without load reduction, is essential to assess the performance of DR strategies, however, there has been very little published research on developing baselines for airports. Therefore, the research described in this paper aims to develop baseline models specifically intended for airport facilities. Specifically, we propose piece-wise linear regression models for predicting electricity demand using time-of-week, temperature, and flight schedule information. We hypothesize that flight schedule information would help explain a significant portion of the load after temperature and time-of-week information has been accounted for. However, the result reveals that a model with time-of-week and temperature as input variables and trained over specific seasonal data have the best prediction performance. The number of passengers of departure flight schedule is shown to have a positive relationship with the load, but does not improve the model accuracy significantly.” image_preview = “” selected = false projects = [] math = true highlight = true [header] image = “” caption = “” +++

We propose an integrated performance analysis framework that automatically collects, merges and provides the information required by them. In previous studies, we have identified a general set of information requirements for the computerized approaches and formalized a semi-automated approach that integrates multiple data models to support the required information. In order to automatically retrieve the information required by different approaches, the research discussed in this paper explored a query mechanism that can represent the required information in a formal way that can be reasoned about. We categorize the information items that are used to represent the information needs, formalize a domain-specific query language that can formally represent the query statements, and develop a library of mechanisms that can automatically reason about and retrieve the needed information. In order to validate the performance of the query language and mechanisms, we also developed a prototype, which includes a graphic user interface that helps users to define the queries, and the implementation of the reasoning mechanisms that process the queries.

Piezoelectric transducers bonded to the pipe produce guided waves that propagate long distances and illuminate the whole pipe, providing a promising tool for pipe structure health monitoring. However it is difficult to recognize the change produced by a scatterer because of the many wave modes and wave paths. Moreover, under operating conditions, the environmental and operational variations produce significant changes in pitch-catch signals, which would produce false-positive results with conventional change detection methods. We instrumented pressurized pipe segments in a working hot-water supply system that experiences ongoing variations in pressure, temperature, and flow rate in an environment that is noisy mechanically and electrically. We conducted pitch-catch tests between transducers located roughly 16 diameters apart on a 10-in. pipe. We show significant environmental and operational variations, even after temperature compensation. At several different time intervals we applied and removed a grease-coupled mass scatterer on the pipe as a physical simulation of damage. We then use singular value decomposition (SVD) to build a change detector that is sensitive to the mass scatterer but insensitive to the changes produced by operational and environmental variations, and we show examples of its successful performance on field experiments data. We show that specific components are associated with the changes produced by the mass scatterer, while others are associated with the environmental variations.” image_preview = “” selected = false projects = [] math = true highlight = true [header] image = “” caption = “” +++

abstract = “Person re-identification is a critical security task for recognizing a person across spatially disjoint sensors. Previous work can be computationally intensive and is mainly based on low-level cues extracted from RGB data and implemented on a PC for a fixed sensor network (such as traditional CCTV). We present a practical and efficient framework for mobile devices (such as smart phones and robots) where high-level semantic soft biometrics are extracted from RGB and depth data. By combining these cues, our approach attempts to provide robustness to noise, illumination, and minor variations in clothing. This mobile approach may be particularly useful for the identification of persons in areas ill-served by fixed sensors or for tasks where the sensor position and direction need to dynamically adapt to a target. Results on the BIWI dataset are preliminary but encouraging. Further evaluation and demonstration of the system will be available on our website.” abstract_short = “”

Data from these sensors are then relayed back to the main meter using a low-latency wireless sensor networking protocol, where changes in the total power consumption of the house are used to determine the power usage of individual appliances. The sensors are low-cost, easy to deploy and are able to detect current changes associated with the appliance from a few inches away making it possible to externally monitor in-wall wiring to devices like overhead lights or heavy machinery that might operate on multiple phases of the AC distribution system of the building.

Current approaches for appliance-level energy metering typically require the installation of plug-through power meters, which is often difficult and costly for devices with inaccessible wires or outlets, or appliances that draw large amounts of current. In this paper, we present an energy measurement system that estimates the energy consumption of individual appliances using a wireless sensor network consisting of contactless electromagnetic field (EMF) sensors deployed near each appliance, and a whole-house power meter. We present the design of a battery-operated EMF sensor, which can detect appliance state transitions within close proximity based on magnetic and electric field fluctuations. Each detector wirelessly transmits state change events to a circuit-panel energy meter, in a time-synchronized fashion, so that the overall power measurements can be used to estimate appliance-level energy usage. The time synchronization and data throughput requirements of this problem motivated the development of a new low-power TDMA sensor networking protocol. Our EMF sensors are able to detect significant power state changes from a few inches away, thus making it possible to externally monitor in-wall wiring to devices. We experimentally evaluate our proposed EMF sensor, three-phase power meter and communication protocol in a residential building collecting data for over a week. The system is able to estimate appliance energy consumption with an average accuracy of 95.8%.” image_preview = “” selected = false projects = [] math = true highlight = true [header] image = “” caption = “” +++

Limitations of current manual data collection approaches in terms of speed, completeness and accuracy render these approaches ineffective for decision support in highly dynamic environments, such as construction and facility operations. Hence, there is a need to leverage the advancements in automated field data capture technologies to support decisions during construction and facility operations. These technologies can be used not only for acquiring data about the various operations being carried out at construction and facility sites, but also for gathering information about the context surrounding these operations and monitoring the workflow of activities during these operations. With this, it is possible for project and facility managers to better understand the effect of environmental conditions on construction and facility operations, as well as to identify inefficient processes in these operations. This paper presents an overview of the various applications of automated field data capture technologies in construction and facility fieldwork. These technologies include image capture technologies such as laser scanners and video cameras, automated identification technologies such as barcodes and Radio Frequency Identification (RFID) tags, tracking technologies such as GPS and Wireless LAN, and process monitoring technologies such as on-board instruments (OBI). The authors observe that though there exist applications for capturing construction and facility fieldwork data, these technologies have been underutilized for capturing the context at the fieldwork sites as well as for monitoring the workflow of construction and facility operations.” image_preview = “” selected = false projects = [] math = true highlight = true [header] image = “” caption = “” +++
