Suppose that a user intends to use a second-hand device for manufacturing products, and that the device is replaced with a new one. Any device failure is rectified through minimal repair, thereby incurring a fixed repair cost to the user. If the new device fails within the FRW period, minimal repair is performed at no cost to the user. After the FRW expires, a failed device is repaired and the cost of repair is incurred by the user. In this study, two profit models were developed, and the optimal replacement time and number of PM actions were determined to maximize profits. Finally, the influence of the optimal replacement time and number of PM actions were elaborated on, using numerical examples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=second-hand%20device" title="second-hand device">second-hand device</a>, <a href="https://publications.waset.org/abstracts/search?q=preventive%20maintenance" title=" preventive maintenance"> preventive maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=replacement%20time" title=" replacement time"> replacement time</a>, <a href="https://publications.waset.org/abstracts/search?q=device%20failure" title=" device failure"> device failure</a> </p> <a href="https://publications.waset.org/abstracts/9223/replacement-time-and-number-of-preventive-maintenance-actions-for-second-hand-device" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9223.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">468</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4260</span> Product Design and Development of Wearable Assistant Device</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hao-Jun%20Hong">Hao-Jun Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Jung-Tang%20Huang"> Jung-Tang Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The world is gradually becoming an aging society, and with the lack of laboring forces, this phenomenon is affecting the nation’s economy growth.

Sweat contains many elements that help in the diagnostic process. In this research, we analyzed sweat samples by using a Colorimeter device to identify the disease of kidney failure in its various stages. This analysis is a non-invasive method where the sample is collected from outside the body, and then this sample is analyzed. Urea refers to the disease of kidney failure when its quantity is high in the blood and then in the sweat, and by experience, we found that the amount of urea for males differs from its quantity for females, where there is a noticeable increase for males in normal and pathological cases. In this research, we took many samples from a normal group that does not suffer from renal failure and another who suffers from the disease to compare the percentage of urea, and after analysis, we found that the urea percentage is high in people with kidney failure disease. with an accuracy of results of 85%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sweat%20analysis" title="sweat analysis">sweat analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=kidney%20failure" title=" kidney failure"> kidney failure</a>, <a href="https://publications.waset.org/abstracts/search?q=urea" title=" urea"> urea</a>, <a href="https://publications.waset.org/abstracts/search?q=non-invasive" title=" non-invasive"> non-invasive</a>, <a href="https://publications.waset.org/abstracts/search?q=eccrine%20glands" title=" eccrine glands"> eccrine glands</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20composition" title=" mineral composition"> mineral composition</a>, <a href="https://publications.waset.org/abstracts/search?q=sweat%20test" title=" sweat test"> sweat test</a> </p> <a href="https://publications.waset.org/abstracts/187068/early-detection-of-kidney-failure-by-using-a-distinct-technique-for-sweat-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187068.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">42</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4258</span> Statistical Analysis of Failure Cases in Aerospace</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20H.%20Lv">J.

Although great effort has been put onto the development of material and system reliability, the failure cases of fatal accidents still occur nowadays. Due to the complexity of the aviation system, and the interaction among the failure components, the failure analysis of the related equipment is a little difficult. This study focuses on surveying the failure cases in aviation, which are extracted from failure analysis journals, including Engineering Failure Analysis and Case studies in Engineering Failure Analysis, in order to obtain the failure sensitive factors or failure sensitive parts. The analytical results show that, among the failure cases, fatigue failure is the largest in number of occurrence. The most failed components are the disk, blade, landing gear, bearing, and fastener. The frequently failed materials consist of steel, aluminum alloy, superalloy, and titanium alloy. Therefore, in order to assure the safety in aviation, more attention should be paid to the fatigue failures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerospace" title="aerospace">aerospace</a>, <a href="https://publications.waset.org/abstracts/search?q=disk" title=" disk"> disk</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20analysis" title=" failure analysis"> failure analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue" title=" fatigue"> fatigue</a> </p> <a href="https://publications.waset.org/abstracts/77819/statistical-analysis-of-failure-cases-in-aerospace" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77819.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">332</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4257</span> Highly-Efficient Photoreaction Using Microfluidic Device</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shigenori%20Togashi">Shigenori Togashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yukako%20Asano"> Yukako Asano</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We developed an effective microfluidic device for photoreactions with low reflectance and good heat conductance.

The defect of metal break located on the step is one of the main failure mechanisms of bipolar ICs, resulting in open-circuit or functional failure. In this situation, general failure localization methods like optical beam-induced resistance change (OBIRCH) and photon emission microscopy (PEM) might not be fully effective. However, active voltage contrast (AVC) can be used as a voltage probe, which may pinpoint the incorrect potential and thus locate the failure position. Two case studies will be present in this paper on how to implement AVC for failure localization, and the detailed failure mechanism will be discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bipolar%20IC" title="bipolar IC">bipolar IC</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20localization" title=" failure localization"> failure localization</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20break" title=" metal break"> metal break</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20failure" title=" open failure"> open failure</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20contrast" title=" voltage contrast"> voltage contrast</a> </p> <a href="https://publications.waset.org/abstracts/132527/failure-localization-of-bipolar-integrated-circuits-by-implementing-active-voltage-contrast" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132527.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">291</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4255</span> A Review on the Re-Usage of Single-Use Medical Devices </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lucas%20B.%20Naves">Lucas B.

This is because videos are now used as evidence in legal proceedings. Source device identification aim at identifying the source of digital devices using the content they produced. However, due to affordable processing tools and the influx in digital content generating devices, source device identification is still a major problem within the digital forensic community. In this paper, we discuss source device identification for digital videos by identifying techniques that were proposed in the literature for model or specific device identification. This is aimed at identifying salient open challenges for future research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=video%20forgery" title="video forgery">video forgery</a>, <a href="https://publications.waset.org/abstracts/search?q=source%20camcorder" title=" source camcorder"> source camcorder</a>, <a href="https://publications.waset.org/abstracts/search?q=device%20identification" title=" device identification"> device identification</a>, <a href="https://publications.waset.org/abstracts/search?q=forgery%20detection" title=" forgery detection "> forgery detection </a> </p> <a href="https://publications.waset.org/abstracts/21641/forensic-challenges-in-source-device-identification-for-digital-videos" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21641.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">631</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4252</span> Analysis of Gas Disturbance Characteristics in Lunar Sample Storage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lv%20Shizeng">Lv Shizeng</a>, <a href="https://publications.waset.org/abstracts/search?q=Han%20Xiao"> Han Xiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Yi"> Zhang Yi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ding%20Wenjing"> Ding Wenjing</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The lunar sample storage device is mainly used for the preparation of the lunar samples, observation, physical analysis and other work. The lunar samples and operating equipment are placed directly inside the storage device. The inside of the storage device is a high purity nitrogen environment to ensure that the sample is not contaminated by the Earth's environment. In order to ensure that the water and oxygen indicators in the storage device meet the sample requirements, a dynamic gas cycle is required between the storage device and the external purification equipment. However, the internal gas disturbance in the storage device can affect the operation of the sample. In this paper, the storage device model is established, and the tetrahedral mesh is established by Tetra/Mixed method. The influence of different inlet position and gas flow on the internal flow field disturbance is calculated, and the disturbed flow area should be avoided during the sampling operation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lunar%20samples" title="lunar samples">lunar samples</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20disturbance" title=" gas disturbance"> gas disturbance</a>, <a href="https://publications.waset.org/abstracts/search?q=storage%20device" title=" storage device"> storage device</a>, <a href="https://publications.waset.org/abstracts/search?q=characteristic%20analysis" title=" characteristic analysis"> characteristic analysis</a> </p> <a href="https://publications.waset.org/abstracts/69595/analysis-of-gas-disturbance-characteristics-in-lunar-sample-storage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69595.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">294</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4251</span> The Influence of Winding Angle on Functional Failure of FRP Pipes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roham%20Rafiee">Roham Rafiee</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadi%20Hesamsadat"> Hadi Hesamsadat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, a parametric finite element modeling is developed to analyze failure modes of FRP pipes subjected to internal pressure.

On the other hand, patients with cardiac pacemakers at the place of a tumor are rather rare, and single clinic hardly has experience with the management of such patients. The widely accepted international guidelines for management of radiation oncology patients recommend that these patients should be closely monitored and examined before, during and after radiotherapy treatment by cardiologist, and their device and condition followed up. The number of patients having both cancer and pacemaker, is growing every year, as both cancer incidence, as well as cardiac diseases incidence, are inevitably growing figures. Materials and methods: Female patient, age 69, was diagnozed with valvular cardiomyopathy and got implanted a pacemaker in 2005 and prosthetic mitral valve in 1993 (cancer was diagnosed in 2012). She was stable cardiologically and came to radiation therapy department with the diagnosis of right breast cancer, with the tumor in upper lateral quadrant of the right breast. Since she had all lymph nodes positive (28 in total), she had to have irradiated the supraclavicular region, as well as the breast with the tumor bed. She previously received chemotherapy, approved by the cardiologist. The patient was estimated to be with the high risk as device was within the field of irradiation, and the patient had high dependence on her pacemaker. The radiation therapy plan was conducted as 3D conformal therapy. The delineated target was breast with supraclavicular region, where the pacemaker was actually placed, with the addition of a pacemaker as organ at risk, to estimate the dose to the device and its components as recommended, and the breast. The targets received both 50 Gy in 25 fractions (where 20% of a pacemaker received 50 Gy, and 60% of a device received 40 Gy). The electrode to the heart received between 1 Gy and 50 Gy. Verification of dose planned and delivered was performed. Results: Evaluation of the patient status according to the guidelines and especially evaluation of all associated risks to the patient during treatment was done. Patient was irradiated by prescribed dose and followed up for the whole year, with no symptoms of failure of the pacemaker device during, or after treatment in follow up period. The functionality of a device was estimated to be unchanged, according to the parameters (electrode impedance and battery energy). Conclusion: Patient was closely monitored according to published guidelines during irradiation and afterwards. Pacemaker irradiated with the full dose did not show any signs of failure despite recommendations data, but in correlation with other published data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cardiac%20pacemaker" title="cardiac pacemaker">cardiac pacemaker</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title=" breast cancer"> breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=radiotherapy%20treatment%20planning" title=" radiotherapy treatment planning"> radiotherapy treatment planning</a>, <a href="https://publications.waset.org/abstracts/search?q=complications%20of%20treatment" title=" complications of treatment "> complications of treatment </a> </p> <a href="https://publications.waset.org/abstracts/28171/cardiac-pacemaker-in-a-patient-undergoing-breast-radiotherapy-multidisciplinary-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28171.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">438</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4249</span> Designing and Analyzing Sensor and Actuator of a Nano/Micro-System for Fatigue and Fracture Characterization of Nanomaterials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Reza%20Zamani%20Kouhpanji">Mohammad Reza Zamani Kouhpanji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a MEMS/NEMS device for fatigue and fracture characterization of nanomaterials. This device can apply static loads, cyclic loads, and their combinations in nanomechanical experiments. It is based on the electromagnetic force induced between paired parallel wires carrying electrical currents. Using this concept, the actuator and sensor parts of the device were designed and analyzed while considering the practical limitations. Since the PWCC device only uses two wires for actuation part and sensing part, its fabrication process is extremely easier than the available MEMS/NEMS devices. The total gain and phase shift of the MEMS/NEMS device were calculated and investigated. Furthermore, the maximum gain and sensitivity of the MEMS/NEMS device were studied to demonstrate the capability and usability of the device for wide range of nanomaterials samples. This device can be readily integrated into SEM/TEM instruments to provide real time study of the mechanical behaviors of nanomaterials as well as their fatigue and fracture properties, softening or hardening behaviors, and initiation and propagation of nanocracks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sensors%20and%20actuators" title="sensors and actuators">sensors and actuators</a>, <a href="https://publications.waset.org/abstracts/search?q=MEMS%2FNEMS%20devices" title=" MEMS/NEMS devices"> MEMS/NEMS devices</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue%20and%20fracture%20nanomechanical%20testing%20device" title=" fatigue and fracture nanomechanical testing device"> fatigue and fracture nanomechanical testing device</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20and%20cyclic%20nanomechanical%20testing%20device" title=" static and cyclic nanomechanical testing device"> static and cyclic nanomechanical testing device</a> </p> <a href="https://publications.waset.org/abstracts/78711/designing-and-analyzing-sensor-and-actuator-of-a-nanomicro-system-for-fatigue-and-fracture-characterization-of-nanomaterials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78711.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">297</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4248</span> Failure Cases Analysis in Petrochemical Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20W.%20Liu">S.

The improvement of petrochemical safety is highly requested in order to prevent re-occurrence of severe accident. This study focuses on surveying the failure cases occurred in petrochemical field, which were extracted from journals of engineering failure, including engineering failure analysis and case studies in engineering failure analysis. The relation of failure mode, failure mechanism, type of components, and type of materials was analyzed in this study. And the analytical results showed that failures occurred more frequently in vessels and piping among the petrochemical equipment. Moreover, equipment made of carbon steel and stainless steel accounts for the majority of failures compared to other materials. This may be related to the application of the equipment and the performance of the material. In addition, corrosion failures were the largest in number of occurrence in the failure of petrochemical equipment, in which stress corrosion cracking accounts for a large proportion. This may have a lot to do with the service environment of the petrochemical equipment. Therefore, it can be concluded that the corrosion prevention of petrochemical equipment is particularly important. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cases%20analysis" title="cases analysis">cases analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=failure" title=" failure"> failure</a>, <a href="https://publications.waset.org/abstracts/search?q=petrochemical%20industry" title=" petrochemical industry"> petrochemical industry</a> </p> <a href="https://publications.waset.org/abstracts/77797/failure-cases-analysis-in-petrochemical-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77797.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">307</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4247</span> Performance Assessment of Three Unit Redundant System with Environmental and Human Failure Using Copula Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20V.%20Singh">V.

The subsystem-1 has three identical units in parallel configuration and operating under 2-out-of-3: G policy and connected to subsystem-2 in series configuration. Each subsystem has different types of failure and repair rates. An important cause for failure of system is unsuitability of the environmental conditions, like overheating, weather conditions, heavy rainfall, storm etc. The environmental failure is taken into account in the proposed repairable system.

The model is a mixture of the three known phases of a component life, the decreasing failure rate (DFR), the constant failure rate (CFR) and the increasing failure rate (IFR) represented by three parametric Weibull models. The parameters are obtained from a simultaneous fitting process of the model to the Kernel nonparametric hazard rate curve. From the Weibull parameters and failure rate curves the useful lifetime and the characteristic lifetime were defined. To demonstrate the model the historic time-to-failure of distribution transformers were used as an example.

In both topologies BUS topology and STAR topology, we have assumed 'n' clients. The system has two types of failure partial failure and complete failure. Further the partial failure has been categorized as minor partial failure and major partial failure. It is assumed that minor partial failure degrades the subsystem and the major partial failure brings the subsystem to break down mode.

Objectives: The aim of our study is to investigate the way in which 100 Tunisian dentists carried implant treatment for their patients from the early phase of planning and selection of patients to the placement of the implant in order to look for the implant failure factors. Results: significant correlations were found between failure rates > 5 and their corresponding factors as the number of implants placed (p = 0.001<0, 05), smoking (0.046 <0.05), unbalanced diabetes (0.03<0.05), aseptic protocol (= 0.004< 0.05) and the drilling speed (0,002<0.05) Conclusion: It seems that the number of implant placed, smoking, diabetes, aseptic protocol, and the drilling speed may contribute to dental implant failure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=failure" title="failure">failure</a>, <a href="https://publications.waset.org/abstracts/search?q=implants" title=" implants"> implants</a>, <a href="https://publications.waset.org/abstracts/search?q=survey" title=" survey"> survey</a>, <a href="https://publications.waset.org/abstracts/search?q=risk" title=" risk"> risk</a>, <a href="https://publications.waset.org/abstracts/search?q=osseointegration" title=" osseointegration"> osseointegration</a> </p> <a href="https://publications.waset.org/abstracts/144098/implantology-failure-epidemiological-survey-among-tunisian-dentists" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144098.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">183</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4238</span> Automatic Battery Charging for Rotor Wings Type Unmanned Aerial Vehicle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeyeon%20Kim">Jeyeon Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes the development of the automatic battery charging device for the rotor wings type unmanned aerial vehicle (UAV) and the positioning method that can be accurately landed on the charging device when landing.

These products are usually highly reliable and little failure information can be collected. In this paper, an analytical method based on data from accelerated storage life test is proposed to evaluate the reliability index of the long-term storage products. Firstly, singularities are eliminated by data normalization and residual analysis. Secondly, with the pre-processed data, the degradation path model is built to obtain the pseudo life values. Then by life distribution hypothesis, we can get the estimator of parameters in high stress levels and verify failure mechanisms consistency. Finally, the life distribution under the normal stress level is extrapolated via the acceleration model and evaluation of the true average life available. An application example with the camera stabilization device is provided to illustrate the methodology we proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accelerated%20storage%20life%20test" title="accelerated storage life test">accelerated storage life test</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20mechanisms%20consistency" title=" failure mechanisms consistency"> failure mechanisms consistency</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20distribution" title=" life distribution"> life distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability" title=" reliability"> reliability</a> </p> <a href="https://publications.waset.org/abstracts/29140/an-evaluation-method-of-accelerated-storage-life-test-for-typical-mechanical-and-electronic-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29140.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">388</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4236</span> Comparison of Two Strategies in Thoracoscopic Ablation of Atrial Fibrillation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Zotov">Alexander Zotov</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilkin%20Osmanov"> Ilkin Osmanov</a>, <a href="https://publications.waset.org/abstracts/search?q=Emil%20Sakharov"> Emil Sakharov</a>, <a href="https://publications.waset.org/abstracts/search?q=Oleg%20Shelest"> Oleg Shelest</a>, <a href="https://publications.waset.org/abstracts/search?q=Aleksander%20Troitskiy"> Aleksander Troitskiy</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Khabazov"> Robert Khabazov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Thoracoscopic surgical ablation of atrial fibrillation (AF) includes two technologies in performing of operation. 1st strategy used is the AtriCure device (bipolar, nonirrigated, non clamping), 2nd strategy is- the Medtronic device (bipolar, irrigated, clamping). The study presents a comparative analysis of clinical outcomes of two strategies in thoracoscopic ablation of AF using AtriCure vs. Medtronic devices. Methods: In 2 center study, 123 patients underwent thoracoscopic ablation of AF for the period from 2016 to 2020. Patients were divided into two groups. The first group is represented by patients who applied the AtriCure device (N=63), and the second group is - the Medtronic device (N=60), respectively. Patients were comparable in age, gender, and initial severity of the condition. Among the patients, in group 1 were 65% males with a median age of 57 years, while in group 2 – 75% and 60 years, respectively. Group 1 included patients with paroxysmal form -14,3%, persistent form - 68,3%, long-standing persistent form – 17,5%, group 2 – 13,3%, 13,3% and 73,3% respectively. Median ejection fraction and indexed left atrial volume amounted in group 1 – 63% and 40,6 ml/m2, in group 2 - 56% and 40,5 ml/m2. In addition, group 1 consisted of 39,7% patients with chronic heart failure (NYHA Class II) and 4,8% with chronic heart failure (NYHA Class III), when in group 2 – 45% and 6,7%, respectively. Follow-up consisted of laboratory tests, chest Х-ray, ECG, 24-hour Holter monitor, and cardiopulmonary exercise test. Duration of freedom from AF, distant mortality rate, and prevalence of cerebrovascular events were compared between the two groups. Results: Exit block was achieved in all patients. According to the Clavien-Dindo classification of surgical complications fraction of adverse events was 14,3% and 16,7% (1st group and 2nd group, respectively). Mean follow-up period in the 1st group was 50,4 (31,8; 64,8) months, in 2nd group - 30,5 (14,1; 37,5) months (P=0,0001). In group 1 - total freedom of AF was in 73,3% of patients, among which 25% had additional antiarrhythmic drugs (AADs) therapy or catheter ablation (CA), in group 2 – 90% and 18,3%, respectively (for total freedom of AF P<0,02). At follow-up, the distant mortality rate in the 1st group was – 4,8%, and in the 2nd – no fatal events. Prevalence of cerebrovascular events was higher in the 1st group than in the 2nd (6,7% vs. 1,7% respectively). Conclusions: Despite the relatively shorter follow-up of the 2nd group in the study, applying the strategy using the Medtronic device showed quite encouraging results. Further research is needed to evaluate the effectiveness of this strategy in the long-term period. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atrial%20fibrillation" title="atrial fibrillation">atrial fibrillation</a>, <a href="https://publications.waset.org/abstracts/search?q=clamping" title=" clamping"> clamping</a>, <a href="https://publications.waset.org/abstracts/search?q=ablation" title=" ablation"> ablation</a>, <a href="https://publications.waset.org/abstracts/search?q=thoracoscopic%20surgery" title=" thoracoscopic surgery"> thoracoscopic surgery</a> </p> <a href="https://publications.waset.org/abstracts/152961/comparison-of-two-strategies-in-thoracoscopic-ablation-of-atrial-fibrillation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152961.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">110</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4235</span> Stochastic Analysis of Linux Operating System through Copula Distribution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vijay%20Vir%20Singh">Vijay Vir Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work is focused studying the Linux operating system connected in a LAN (local area network).

In the both topologies BUS topology and STAR topology, we have assumed n clients. The system has two types of failures i.e. partial failure and complete failure. Further, the partial failure has been categorized as minor and major partial failure. It is assumed that the minor partial failure degrades the sub-systems and the major partial failure make the subsystem break down mode. The system may completely fail due to failure of server hacking and blocking etc. The system is studied using supplementary variable technique and Laplace transform by using different types of failure and two types of repair.

In this paper, we propose a secure transmission scheme in D2D multicast communications in cellular networks.

There were two objectives of this study. The first objective was to investigate the effect of non-chemical treatments on damage of bamboo shading device by powder-post beetle and fungi. The second aim of this study was to develop a prototype of bamboo shading device. The study of the effect of non-chemical treatments on damage of bamboo shading device by powder-post beetle in laboratory showed that, among seven treatments tested, wood vinegar treatment can protect powder-post beetle better than the original method up to 92.91%. It was also found that wood vinegar treatment can show the best performance in fungi protection and work better than the original method up to 40%. The second experiment was carried out by constructing four bamboo shading devices and installing them on a building for 28 days. All aspects of shading device were investigated in terms of their beauty, durability, and ease of construction and assembly. The final prototype was developed from the lessons drawn from these tested options. In conclusion this study showed the effectiveness of some natural preservatives against insect and fungi damage. It also illustrated the characteristics of the prototype of bamboo shading device that can constructed by rural workers within one week. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bamboo" title="bamboo">bamboo</a>, <a href="https://publications.waset.org/abstracts/search?q=shading%20device" title=" shading device"> shading device</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20conservation" title=" energy conservation"> energy conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=alternative%20material" title=" alternative material"> alternative material</a> </p> <a href="https://publications.waset.org/abstracts/26400/the-development-of-the-prototype-of-bamboo-shading-device" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26400.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">378</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4232</span> Bluetooth Piconet System for Child Care Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ching-Sung%20Wang">Ching-Sung Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Teng-Wei%20Wang"> Teng-Wei Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhen-Ting%20Zheng"> Zhen-Ting Zheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study mainly concerns a safety device designed for child care. When children are out of sight or the caregivers cannot always pay attention to the situation, through the functions of this device, caregivers can immediately be informed to make sure that the children do not get lost or hurt, and thus, ensure their safety. Starting from this concept, a device is produced based on the relatively low-cost Bluetooth piconet system and a three-axis gyroscope sensor. This device can transmit data to a mobile phone app through Bluetooth, in order that the user can learn the situation at any time. By simply clipping the device in a pocket or on the waist, after switching on/starting the device, it will send data to the phone to detect the child’s fall and distance. Once the child is beyond the angle or distance set by the app, it will issue a warning to inform the phone owner. <p class="card-text"><strong>Keywords:</strong> <a
