We propose EC3, a novel algorithm that merges classification and clustering together in order to support both binary and multi-class classification. EC3 is based on a principled combination of multiple classification and multiple clustering methods using a convex optimization function. We additionally propose iEC3, a variant of EC3 that handles imbalanced training data. We perform an extensive experimental...
To try to decrease the preference of the attribute values for information gain and information gain ratio, in the paper, the authors puts forward a improved algorithm of C4.5 decision tree on the selection classification attribute. The basic thought of the algorithm is as follows: Firstly, computing the information gain of selection classification attribute, and then get an attribute of the information...
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...
Code bloat is a phenomenon in Genetic Programming (GP) that increases the size of individuals during the evolutionary process. Over the years, there has been a large number of research that attempted to address this problem. In this paper, we propose a new method to control code bloat and reduce the complexity of the solutions in GP. The proposed method is called Substituting a subtree with an Approximate...
Distributed manufacturing, where decentralized small, local sites are engaged in production, often supported by digital systems and networks, can be a powerful tool in humanitarian aid. Field Ready uses distributed manufacturing to produce essential non-food items locally where they are needed during humanitarian responses. Such supplies can be available to communities in need and to relief workers...
Direct current internal resistance (DCIR) is a key parameter to determine consistency of power characteristics of a battery pack. This consistency is influenced by batteries' internal temperature, which reflects consistency of the batteries' thermal characteristics inherently. In this paper, an evaluation method for thermal consistency of batteries' DCIR is proposed. Arrhenius coefficient of DCIR...
Spreadsheets serve as a basis for decision-making processes in many companies and bugs in spreadsheets can therefore represent a considerable risk to businesses. Systematic tests can help to locate such bugs, but providing test cases can be cumbersome and complex for large real-world spreadsheets. To make the specification of test cases easier, we propose to split spreadsheets into smaller logically...
This paper describes two concepts of automatic systems for accuracy testing of current transformers. Advantages and disadvantages of both concepts are discussed. The concept of multi channel testing is used for developing of the measuring device for current transformer accuracy testing for factory FMT Zajecar. The short description of the device is presented as well as the results of its testing.
Based on the analysis of current conditions and shortages of the configuration files management in smart substation, the problems existing in current conditions are proposed, such as: ICD test technology, SCD test technology, SCD difference comparison technology. In order to meet the demand of the large scale smart substation construction, a solution of building the smart substation configuration...
Line impedance stabilization network (LISN) is an important tool to provide noiseless power supply in electromagnetic compatibility (EMC) testing. There are several brands of LISN that are recognized in the market. However, the quality of measurement provided by the LISN is not dependent upon the quality of the product, but also its application scheme. This paper investigates the effect of grounding...
This paper presents some aspects on measurements of radiated emission from a Laptop. The used Standards are presented and discussed. The measurements were carried out in a Semi-Anechoic Chamber (SAC) in accordance with EN 55022 (CISPR 22) Standard. The test arrangement was in accordance with IEC 61000-4-3 Standard and the following equipment was included: reception antenna, signal generator and emission...
The document targets towards analysis current braille characters, emphasis it's insufficiencies at instructing approaches aimed at little kids with recommend apparent results. This document concentrates largely upon the practice of braille and typography collectively with the fundamental braille writing system and is essential for constructive progress in association for blind kids. The principal...
The application of single crystals in acousto-, opto-, micro — and nanoelectronics defines strict requirements to crystals and crystal elements as well as the need for certification of these products. The use of single crystals in acousto-, opto-, micro — and nanoelectronics defines strict requirements both to crystals and crystal elements, and it concurrently defines the need for the certification...
Modern systems are becoming ever more complex and, thus, the possibility of failures in their operation is also growing. The complexity makes it practically impossible to make the hardware and software error-free without the special effort invested in the design process. Recently, a design methodology with the objective to avoid unacceptable risk of physical injury or of damage to the health of people,...
This article discusses the aspects of quality and tests, whose definitions came from Software Engineering, and its application in OER (Open Educational Resources) design and repurposing. This proposal is intended to support people, playing different roles, interested in using, creating or adapting OER. It is hoped that through the test descriptions, producing teams or individual creators would be...
The shock absorber Electro-hydraulic Servo-testing system conformed to national standard QC/T 545–1999 is designed, error compensating PID regulation method which is appropriate for signal condition was applied. According to use the MTS407 controller and LabVIEW virtual instrument software, implement dynamometer diagram testing, speed diagram testing, friction diagram testing, temperature wearing...
Hardware-in-the-Loop (HIL) is a well-established concept for developing and testing embedded systems. While it is widely used in industrial automation and the automotive area, it is rarely applied to Building Automation Systems (BAS). This work proposes the interconnection of a prominent building automation protocol, namely Building Automation and Control network (BACnet), and a simulator, PowerDEVS,...
Many analog and mixed signal devices have very few or no digital pins. In spite of this, these products can be highly complex internally, including significant digital content. They may contain various sensors and control circuitry, which react to a variety of conditions to control the power profile of the part and its environment. These factors can make these devices very challenging to test. They...
The classification and identification of the bird species from the visual image is complex compared by using audio song. The knowledge of the features species type is very important as to ensure it is classified to the correct species. Color-based feature extraction is one of the procedure in extracting the color properties from the bird which to represent the species of the bird. However, it is a...
This paper describes the design and testing process of low power current sensors using PCB rogowski-coil for high current application. The design and testing process of PCB rogowski-coil transducer and electronic circuit are explained in deeply analyze based on the physical structure. It also reveals the linearity and error rates of PCB rogowski-coil current sensors. Tests carried out using Current...
