This study employs AI to classify the vibration states of equipment during operation to ensure the health of the equipment. Initially, a vibration simulation system was established in the laboratory using a servo motor. The digitized data measured by a vibration sensor was transmitted to a PC and stored in SQLite. The vibration data was then applied to a Temporal Convolutional Network (TCN) model for training. After completing the capability of status identification in the vibration simulation system, the model was applied to the water-pumping motor of the water circulation system in the Wire Electrical Discharge Machine (WEDM). The intelligent vibration status diagnosis system identified whether the operation of the WEDM water circulation system was normal at different water-pumping motor speeds. This reduces the need for manual equipment fault detection and allows for immediate detection of motor status, minimizing accidents and product losses.

To assist doctors more effectively in clinical diagnosis, a lightweight system using Phonocardiogram (PCG) for early detection of Cardiovascular diseases (CVDs) has been developed. It employs short-time Fourier transform (STFT) and a Maxout residual network (MaxResNet) for heart valve disease recognition. Results from 10-fold cross-validation show a 99% recognition accuracy with only 0.16M parameters. Compared to Karhade et al.’s approach, this method achieves similar accuracy while reducing parameter usage by 87%. Additionally, it achieves real-time performance on Raspberry Pi, taking only 6 ms to recognize 1.1 seconds of PCG recordings.

Water hyacinth has become widespread in freshwater bodies in several countries, leading to various issues, particularly its substantial water consumption and the resulting need to control its growth. Among the different methods of controlling water hyacinth, mechanical control stands out as the most effective and environmentally friendly approach. A proposed harvester robot has been developed, capable of efficiently cutting and collecting water hyacinth from the water's surface. The robot boasts several advantages, including its ability to operate in narrow water paths and lakes, use clean energy sources to preserve the water ecology, employ a GPS module for safety and error detection, and generate maps for evaluating work and predicting annual growth. When compared to other technologies dealing with water hyacinth, this innovative water hyacinth harvesting robot presents a significantly lower cost of 0.01 $/kg, making it an optimal solution for addressing water hyacinth problems.

International Conference on (ICEPT) Electronic Packaging Technology

作者： Xiao-ling Lin Meng Li Qing-zhong Xiao Xiao-wen Zhang Science and Technology on Reliability Physics and Application of Electrical Component Laboratory China Electronic Product Reliability and Environmental Testing Research Institute Guangzhou 510610 China Machinery Engineering and Automation Program Changchun University 130022 China

Based on the stress induced void theory, three kinds of narrow-wide two-layer copper interconnection structure with dummy via in M1 were designed and put under different high temperature conditions for test. Under the action of high temperature, influence of dummy vias in lower layer metal (M1) on the failure phenomenon of the interconnect structure was analyzed. The result shows, adding dummy via in M1 can effectively improve the SIV performance of copper interconnection. Based on this, a more accurate equation was put forward to describe the behavior of the vacancy in the structure with dummy via spreading from the diffusion source to the accumulation.

A portable shape-shifting mobile robot system named as Amoeba Ⅱ（A-Ⅱ） is developed for the urban search and rescue application. It is designed with three degrees of freedom and two tracked drive systems. This robot consists of two modular mobile units and a joint unit. The mobile unit is a tracked mechanism to enforce the propulsion of robot. And the joint unit can transform the robot shape to get high environment adaptation. A-Ⅱ robot can not only adapt to the environment but also change its body shape according to the locus space. It behaves two work states including the linear state （named as I state） and the parallel state （named as Ⅱ state）. With the linear state the robot can climb upstairs and go through narrow space such as the pipe, cave, etc. The parallel state enables the robot with high mobility on rough ground. Also, the joint unit can propel the robot to roll in sidewise direction. Two modular A-Ⅱ robots can be connected through jointing common interfaces on the joint unit to compose a stronger shape-shifting robot, which can transform the body into four wheels-driven vehicle. The experimental results validate the adaptation and mobility of A-Ⅱ robot.

The Plasma Arc Waste Destruction System (PAWDS) uses plasma energy, with temperatures over 5,000 degrees C, to rapidly and efficiently destroy combustible waste aboard ships. PAWDS has proven itself to be a viable alternative to traditional incinerators. >> In September 2003, Carnival Cruise Lines were the first to install a PAWDS aboard their 2,056 passenger (plus 1,000 crew members) capacity, M/S Fantasy cruise ship, to treat ship waste including paper, cardboard, plastics, textiles, wood, and food. As of June 2004, it is being operated and maintained solely by Carnival Cruise Lines personnel and has been permitted to operate in port by the Bahamian port authorities. >> The Navy's next generation aircraft carrier, CVN 21, will be equipped with two FAWDS to process all of the non-food combustible solid waste generated with sufficient system redundancy. The US Navy has been jointly developing the PAWDS with PyroGenesis Inc. over the last 6 years. The development efforts in 2004 and 2005 coupled with lessons learned from operation aboard Carnival's cruise ship have resulted in the identification of additional process and design improvements. Source emission testing by an independent laboratory has also demonstrated that the PAWDS easily meets IMO MARPOL requirements for the destruction of solid waste.

From 1964 to 1974 he was with Hughes Aircraft Company. At Hughes he performed analyses and developed designs for a wide variety of program and proposal efforts such as: High Speed Ground Transportation (DOT) Task Force Command Center (NAVY) Panama Canal Marine Traffic Control Center (Panama Canal Co.) Royal Iranian Navy Command Center (Iran) Tactical Information Processing and Interpretation Center (Air Force) and WALLEYE CONDOR and PHOENIX Missile Systems (NAVY). He also had marketing development responsibilities related to the diversification of Hughes resources in civil business areas such as: Automatic train control (WMATA BARTD SCRTD) water/sewage treatment plant automation (Santa Clara County) Aqueduct Control (SWR) Hydrometeorological data collection (BPA WMO) and Salton Sea basin systems analysis (Dept. of the Interior). He was responsible for combat system integration for the Hughes 2000T Surface Effect Ship (SES) proposal. He also conducted detailed studies concerning ship flexure for the Improved Point Defense Target Acquisition System Program and for the definition of operational High Energy Laser weapon installations on a series of conventional monohulls (DLG DD and CVN). Since 1974 Mr. Luedeke has been employed at RMI Inc. (formerly Rohr Marine Inc.). During this time he has held several positions. His responsibilities have included directing a number of studies on advanced SES concepts managing activities defining mission/cost effectiveness of military and commercial SES's including defining the operational benefits and enhanced survivability characteristics of cargo SES's for high speed military sealiftfor NA TO and Southeast Asia

This paper will present the results of a marketing, engineering, and economic analysis of advanced marine vehicles done by IMA Resources, Inc. and RMI, Inc., in support of a Maritime Administration project to study “Multimode Express Shipping”. The study was conducted in 1981 and examined the economic benefits of using advanced marine vehicles as express cargo vessels in domestic and international service. Commodity characteristics, desirable express carrier rates, and potential high payoff service and route alternatives were identified. Advanced marine vehicles were surveyed and sized to meet desirable deadweight and block speed objectives. The costs of operating these craft on a variety of trade routes were calculated using an advanced marine vehicle economic analysis program. Revenues, expenses, break-even, profit and loss, cash flow requirements, tax summary and economic indicators (i.e., cost/ton – mile, etc.) were projected over the expected life of the vehicles as was return on investment. Traffic density and market penetration considerations narrowed the field of choice to smaller sized advanced marine vehicle carriers (i.e., 50 and 250 ton deadweight) and to three international and five domestic routes.

One of the most serious problems encountered in Naval steam plants following World War II was the unreliable performance of boiler and main feedpump pneumatic control systems. In addition to control component and system design deficiencies, these control systems suffered from inadequate methods to measure and adjust system alignment. This paper describes the development of a set of procedures for on-line alignment verification (OLV) of pneumatic main boiler and feedpump control systems. The procedures are designed for use by N avy control system technicians and, in addition to on-line alignment verification, provide guidance for troubleshooting and for performing system alignment. Procedure static checks measure steady state steaming performance and OLV procedure dynamic checks measure the ability of the boiler and control systems to respond to load changes. The paper describes typical control system characteristics that influence OLV procedure content and the supporting analysis that was used to establish alignment criteria ranges that satisfy both steady state and transient performance requirements. Also described is the alignment criteria tolerance analysis along with the steps involved in a typical OLV check procedure development. Descriptions of the various OLV checks, troubleshooting procedures and alignment procedures are provided. Typical shipboard implementation requirements are described and experience to date with the procedures is provided along with a status report on OLV procedure implementations.
