Optimal Trend Labeling in Financial Time Series

Predicting asset price trends is often posed as a classification problem, where trends are classified as positive or negative. Since asset price series are noisy and volatile, it is difficult to distinguish true trends from short-term fluct...

Convolutional Neural Network Based Approval Prediction of Enhancement Reports

For a given software enhancement report, identifying its possible approval status could help software developers by suggesting feature enhancements to compete in the software industry. An automatic solution for the approval prediction of en...

Exposure of children to multiple long-term air pollutants (PM(2.5), BC, NO(2)) and noise at home and school in accra, Ghana.

Investigation of a Low-Speed Commutation Voltage Shock Problem in Three-Level ANPC Inverter with Hybrid Modulation Mode

With the development of the photovoltaic industry; there will be an increasing demand for efficient, high-power density, and low-cost grid interface converters. Compared with two-level inverters, multilevel inverters have the following adva...

Data-Driven Cervical Cancer Prediction Model with Outlier Detection and Over-Sampling Methods

Globally, cervical cancer remains as the foremost prevailing cancer in females. Hence, it is necessary to distinguish the importance of risk factors of cervical cancer to classify potential patients. The present work proposes a cervical can...

The delineation of an interdisciplinary specialty in terms of a journal set: The case of communication studies

Abstract A journal set in an interdisciplinary or newly developing area can be determined by including the journals classified under the most relevant ISI Subject Categories into a journal–journal citation matrix. Despite the fuzzy characte...

Microwave Photonic Techniques in Phase-Noise Measurements of Microwave Sources: A Review of Fiber-Optic Delay-Line Methods

Microwave photonics has recently come to the forefront as a valuable approach to generating, processing, and measuring signals in high-performance domains such as communication, radar, and timing systems. Recent studies have introduced a ra...

Multi‐antenna joint covert communication with a public communication link over wireless fading channel

Abstract This paper studies multi‐antenna covert communication exploiting a public communication link over the wireless fading channel. In particular, a relatively practical covert communication scenario is considered for the first time, wh...

The Architecture of an Automatic eHealth Platform With Mobile Client for Cerebrovascular Disease Detection

BackgroundIn recent years, cerebrovascular disease has been the leading cause of death and adult disability in the world. This study describes an efficient approach to detect cerebrovascular disease. ObjectiveIn order to improve...

A study of aerodynamic noise in air duct systems with turning vanes

Noise is becoming one of the problems in many industrial applications. In this paper the aerodynamic noise in air duct system that arises from air flow passing over a surface of turning vanes is investigated. Based on Proudman's formula usi...

Research progress of automated ultrasonic imaging detection technology for complex aircraft components

Traditional ultrasonic automated non-destructive testing is a great challenge in the inspection of aviation components with complex surfaces. Complex surfaces can interfere with the formation of the focus in the sound beam，and the waveform ...

Separate DOD and DOA Estimation for Bistatic MIMO Radar

A novel MUSIC-type algorithm is derived in this paper for the direction of departure (DOD) and direction of arrival (DOA) estimation in a bistatic MIMO radar. Through rearranging the received signal matrix, we illustrate that the DOD and th...

An improved Harris corner detection method for honeycomb structures

Structural defects and cell irregularity significantly impact the performance and safety of honeycomb structures. Thus, various image processing techniques have been employed to evaluate the cell shape and detect structural defects within t...
