Obesity is increasing globally and is a risk factor for many chronic conditions such as such as heart disease, sleep apnea, type-2 diabetes, and some cancers. Research shows that food logging is beneficial in promoting weight loss. Crowdsourcing has also been used in promoting dietary feedback for food logging. This work investigates the feasibility of crowdsourcing to provide support in accurately...
We describe a general technique that yields the first Statistical Query lower bounds} fora range of fundamental high-dimensional learning problems involving Gaussian distributions. Our main results are for the problems of (1) learning Gaussian mixture models (GMMs), and (2) robust (agnostic) learning of a single unknown Gaussian distribution. For each of these problems, we show a super-polynomial...
This paper presents an approach to predict Quality of Experience (QoE) in WLAN networks based on information extracted from non-intrusive measurements which only require control and management frame capture. This procedure avoids costly equipment and it is forward compatible. Specifically, three measurements have been taken: the relative time duration of clear-to-send messages, the percentage of blocked...
The article considers the approach to scanners testing. It is shown that a scanner includes two main channels: channel of photoelectric conversion and channel of measurement of objects spatial co-ordinates. Despite the fact that both channels include virtually the same elements, channel parameters testing should be separated. For this purpose, a special structure of a two-dimensional reference signal...
This paper discusses a series of research challenges in the design of systems of mechatronic systems. A focus is given to environmental mechatronic applications within the chain “Renewable energy production — Smart grids — Electric vehicles”. For the considered mechatronic systems, the main design targets are formulated, the relations to state and parameter estimation, disturbance observation and...
This paper aims toward joining the ideas of OBT (oscillation-based testing) and DFT (design for testability). It gives insight into an optimization process that provides testability if one chooses to use the OBT. The optimization procedure is exemplified on a timer device NE555. Utilization of a timer circuit allows avoidance of a specific design of the feed-back loop. The optimization procedure is...
In the early 1990s, the Modified Condition/Decision Coverage (MC/DC) criterion was suggested as a structural white-box testing approach, but it can also be used for black-box specification-based testing. Practical application of MC/DC for specification-based testing has its own unique features and sometimes is quite different from code-based applications. However, MC/DC as a black-box approach has...
Semiconductor manufacture companies make an effort to reduce the test time for the test cost reduction until mass production starts. One of the effective test time reduction techniques is to improve the parallel test efficiency with the test program optimization by debugging on the automatic test equipment (ATE). However, given the time constraints of production schedules, the available time for the...
Simulating/Measuring the jitter tolerance of clock and data recovery (CDR) circuits, and confirming if the associated jitter tolerance meets the required specification for a specified communication standard, is an important consideration for designing/testing high-speed serial link interface circuits. However, conducting such performance evaluations are costly and time-consuming. In this paper, a...
One of the key tasks of Outdoor-type mobile robotics is traversability estimation of underlying surfaces in a in a priori of an unknown heterogeneous environment. The paper presents practical realization of traversability estimation system based on group method of data handling (GMDH). This method is classical technique of data mining and one of the first techniques of Deep Learning. The results of...
The article considers the architecture of an information system for automating the testing of user interfaces based on the use of Internet technologies. The general description of the system operation, the description of the main modules, the structure of the interface of the Internet resource are given.
This paper provides an overview of the (sub) mm wave testing capabilities at the European Space Agency and contributes the efforts of the community in the estimation of measurement uncertainty for antenna testing in the THz domain.
Knowing the execution time of test cases is importantto perform test scheduling, prioritization and progressmonitoring. This work in progress paper presents a novelapproach for predicting the execution time of test cases basedon test specifications and available historical data on previouslyexecuted test cases. Our approach works by extractingtiming information (measured and maximum execution time)for...
Good planning and managing software test process require accurate estimation of software test effort. This becomes particularly significant when validation and verification activities are to be performed by an independent organization. This study presents a systematic literature review and a follow up industrial survey, which was performed to investigate the state of the art on software test effort...
This paper presents a novel background subtraction method that is flexible for various background scenarios. The method includes automated-directional masking (ADM) algorithm for adaptive background modeling and historical intensity pattern reference (HIPaR) algorithm for foreground segmentation. By selecting an appropriate mask in a set based on directional feature, ADM updates background smoothly...
As China's railway transport system is getting busier and the trains are continually speeding up, the rails have to bear more and more heavy cyclic loads generated by the repeat force between the wheels and rails, and the internal damages are easier to be produced, which directly endanger the running safety. Therefore, it is badly in need of rail flaw detection equipment with high efficiency, more...
Surveillance video parsing, which segments the video frames into several labels, e.g., face, pants, left-leg, has wide applications [41, 8]. However, pixel-wisely annotating all frames is tedious and inefficient. In this paper, we develop a Single frame Video Parsing (SVP) method which requires only one labeled frame per video in training stage. To parse one particular frame, the video segment preceding...
This paper deals with deep neural networks for predicting accurate dense disparity map with Semi-global matching (SGM). SGM is a widely used regularization method for real scenes because of its high accuracy and fast computation speed. Even though SGM can obtain accurate results, tuning of SGMs penalty-parameters, which control a smoothness and discontinuity of a disparity map, is uneasy and empirical...
The main objective of this study is to estimate the relationship between foreign direct investment (FDI), trade openess, and economic growth in Lao PDR. This article uses time series data from 1990 to 2015. To utilizeswith the most advance technique of bounds testing (ARDL) Cointegration Approach. More over, the Vector Error Correction (VECM) has been investigated to study the long run and short run...
This paper examines the single-event upset response of a customer memory interface design on the Xilinx 20nm XCKU040 Field Programmable Gate Array (FPGA) irradiated with 64MeV proton source.
