Software testing is an important issue in software engineering. As systems become increasingly large and complex, the problem of how to optimally allocate limited resource during phase has more important, difficult. Traditional Optimal Testing Resource Allocation Problems (OTRAPs) involve seeking optimal allocation a amount number activities with respect some objectives (e.g., reliability, or cost). We suggest solving OTRAPs Multi-Objective Evolutionary Algorithms (MOEAs). Specifically, we...
The Redundancy Allocation Problem (RAP) is a kind of reliability optimization problems. It involves the selection components with appropriate levels redundancy or to maximize system under some predefined constraints. We can formulate RAP as combinatorial problem when just considering level, while continuous level. employed in this paper that During past thirty years, there have already been number investigations on RAP. However, these often treat single objective only goal (or minimize...
Redundancy allocation problems (RAPs) have attracted much attention for the past thirty years due to its wide applications in improving reliability of various engineering systems. Because RAP is an NP-hard problem, and exact methods are only applicable small instances, heuristic meta-heuristic been proposed solve it. In literature, most studies on RAPs conducted single-level However, real-world systems usually contain multiple levels. this paper, multi-level investigated. A novel memetic...
Protection suit is vital for fireman’ safety. Traditional protection just physically protects fireman from empyrosis, but can not locate the body injury position impact debris. Herein, we present a wearable debris positioning system alarming based on accelerometer array. The piezoelectric accelerometers with distribute regularly to detect vibration different parts, which conducive injured parts. In addition, parts be displayed dummy model upper computer higher localization accuracy of 4 cm....
Scheduling aircraft landings has been a complex and challenging problem in air traffic control for long time. In this paper, we propose to solve the landing scheduling (ALSP) using multi-objective evolutionary algorithms (MOEAs). Specifically, consider simultaneously minimizing total scheduled time of arrival cost, formulate ALSP as 2-objective optimization problem. A MOEA named Multi-Objective Neighborhood Search Differential Evolution (MONSDE) is applied ALSP. Besides, ranking scheme...
Protection suits are vital for firefighters' safety. Traditional protection physically protect firemen from burns, but cannot locate the position of bodily injuries caused by impact debris. Herein, we present a wearable debris positioning system firefighter based on an accelerometer array. Wearable piezoelectric accelerometers distributed regularly suit to detect vibration different body parts, which is conducive determining injured parts. In addition, parts can be displayed dummy model...
Nowadays, as the software systems become increasingly large and complex, problem of allocating limited testing-resource during testing phase has more difficult. In this paper, we propose to solve allocation (TRAP) using multi-objective evolutionary algorithms. Specifically, formulate TRAP two problems. First, consider reliability system cost objectives. second formulation, total consumed is also taken into account third goal. Two algorithms, Non-dominated Sorting Genetic Algorithm II (NSGA2)...
In this study, quasi-static compression, tensile, shear, and combined compression-shear tests are conducted on cast AZ91D magnesium (Mg) alloy to study its fracture behavior. Shear-compression specimens applied instead of complex loading device obtained the response Mg under mixed compression/shear tests. Results show that stress states can be controlled by changing angle. The strength differential effect is observed, criterion with von Mises form cannot give an appropriate description...
The resource-related, environmental and ecological problems raised by building construction activities have drawn a wide range of concerns among researches, especially in China. Those become prominent. In last decade, the life cycle emissions energy efficiency been researched widely. Most studies focus on assessment models emission analysis based available project data statistical data. Very few them study from view structure design, which can reduce at source. This review summarizes...
Crack propagation in ceramics is a highly quick, complex, and nonlinear process that occurs under thermal shock. It challenging to directly observe the evolution of cracks experiments due high speed unpredictability crack propagation. Based on phase-field fracture method, numerical model combined with mechanical damage established analyze path, velocity, morphology pre-cracked ceramic plates flame shock loading. This research primarily focuses impact prefabricated angle length According...
Quasi-static indentation tests were conducted to characterize the mechanical behavior of honeycombs. The local failure mechanisms honeycombs with different relative density discussed in detail. Results showed that spread area tearing deformations increases increasing and difference neatness edges are obvious under indenter shapes sizes. effects geometry on plateau force energy absorption analyzed. tear specimens was determined, an empirical formula proposed describe relationship geometry.
In this paper, the anisotropic mechanical properties of rolled AZ31 magnesium alloys are investigated using nanoindentation tests at room temperature. Nanoindentation was carried out four angles, including rolling direction (0°), diagonal (45°), transverse (90°), and vertical (ND). Experimental results show that hardness increases as angle from 0° to 90° is lowest in ND direction. The independent effect indentation depth obtained by analyzing size then converting values into yield strengths....
