Through and comprehensive tests are necessary to ensure complete stability and reliability of AUV, due to the high risk and consumption of in field testing, onshore testing technology for AUV is proposed. Rudder load simulator plays an important role in the onshore testing of AUV. In this paper, the design and development of a rudder load simulator was discussed. Rudder load calculation method during...
This work presents the lessons learned and critical updates to the Research Oriented Underwater Glider for Hands-on Investigative Engineering (ROUGHIE). The open water testing experience with the original ROUGHIE provides key insight to design and operation of small scale autonomous underwater vehicles. This paper is organized to share necessary considerations that will be crucial for future vehicle...
Downsizing the Cu signal traces in the redistribution layer is an effective approach to increasing the number of signal I/O lines and thereby greatly increasing signal processing performance between logic and memory chips in advanced fine-pitch packaging. Downsized Cu traces, however, are vulnerable to current stress, which degrades electromigration resistance. This is a serious problem in advanced...
Emergency protection of objects in the process of testing and functioning should respond to a wide range of abnormal situations: malfunctions, which can be eliminated during testing; emergency situations that can be eliminated in the operational mode, or require the shutdown of the process and the elimination of the consequences of the accident; catastrophic situations that require an a priori reaction...
Massive Open Online Courses (MOOCs) focus on manifold subjects, ranging from social sciences over languages to technical skills, and use different means to train the respective skills. MOOCs that are teaching programming skills aim to incorporate practical exercises into the course corpus to give students the hands-on experience necessary for understanding and mastering programming. These exercises,...
The purpose of this research is proposing a theory to verify the influence of virtual props trading sites to game loyalty of players. The objects of sampling aims at users who are actually engaged in online games props trading sites. A survey of 459 game players in Taiwan was conducted; research results were generated through the use of descriptive analysis, reliability analysis, correlation analysis,...
Computer Science 2 is one of the core elements of any computer science program; however, there has been little progress towards the development of a concept inventory for this key introductory course for CS majors. Plans to address this gap using the Delphi method are presented. Instructors and researchers with knowledge and experience of CS2 are being recruited to help identify concepts from CS2...
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...
Multiple SDN applications can make several harmful interferences unintentionally, although each individual application may be properly developed. This paper proposes a Multiple SDN Applications Interference Detector (MSAID). To bridge the gap between the source code of applications and the actual interferences, we leverage symbolic execution and constraint solving to obtain how the event handler handles...
Machine learning has become one of the go-to methods for solving problems in the field of networking. This development is driven by data availability in large-scale networks and the commodification of machine learning frameworks. While this makes it easier for researchers to implement and deploy machine learning solutions on networks quickly, there are a number of vital factors to account for when...
In this paper, we propose an SLA-based approach to private cloud reliability. We examine how to formulate reliability SLAs, identify key customer scenarios and use accelerated testing to validate them. We propose the creation of a public cloud SaaS to enable the above reliability validation via a distributed, scalable model. We then illustrate an application of the above approach during the development...
This paper presents aspects of the technical evolution in micro-networks efficiency with respect to the power quality and system availability. Different potential approaches for market using are shown. The environmental and economic effects of the micro-networks depends of their implementing phases, like design, commissioning and testing. It can be a lot different than the normal main grid, depending...
This paper presents a in situ on-chip micro tensile fracture strength tester, which is based on a thermal actuated test platform. In this test platform, tensile fracture strength could be extracted and process could be evaluated, there are two samples with same layout but fabricated under different process conditions were evaluated through this test platform and the results showed that this test platform...
The emergence of large-scale dynamic sets in real applications creates stringent requirements for approximate set representation structures: 1) the capacity of the set representation structures should support flexibly extending or reducing to cope with dynamically changing of set size; 2) the set representation structures should support reliable delete operation. Existing techniques for approximate...
Storage reliability of the ammunition dominates the efforts in achieving the mission reliability goal. Prediction of storage reliability is important in practice to monitor the ammunition quality. In this paper we provided an integrated method where particle swarm optimization (PSO) algorithm is applied to adjust and optimize the BP neural network global parameters (weights and thresholds). The experiment...
Existing video event classification approaches suffer from limited human-labeled semantic annotations. Weak semantic annotations can be harvested from Web-knowledge without involving any human interaction. However such weak annotations are noisy, thus can not be effectively utilized without distinguishing its reliability. In this paper, we propose a novel approach to automatically maximize the utility...
Through ever changing terms and regulations on fuel consumption and emissions, weight becomes the number one concern of car manufacturers. Meeting those new regulations and the customer's desire for more options and variations is only possible without adding more weight by changing the wiring harnesses' technology. One solution to face this problem can be found by the application of flexible flat...
This paper reveals that the standard test procedures for the qualification and verification of traction battery systems are not sufficient in certain cases. In fact, realistic and application-oriented tests on the interaction among the complex battery subsystems are inevitable. To achieve these objectives, a high-performance test bench with the unique selling features of a high voltage/- and current...
A novel approach of a test environment for embedded networking nodes has been conceptualized and implemented. Its basis is the use of virtual nodes in a PC environment, where each node executes the original embedded code. Different nodes run in parallel, connected via so-called virtual channels. The environment allows to modifying the behavior of the virtual channels as well as the overall topology...
Today, performing life tests on power semiconductor devices is of major importance in industrial and automotive power applications. Traditionally, qualification tests, like the HTOL test, are carried out in a semi-automated manner. This paper first reviews different test methods and a recently proposed modular test system (MTS) that allows testing of individual devices as well as application specific...
