摘要： A significant number of cloud storage environments are already implementing deduplication technology.Due to the nature of the cloud environment,a storage server capable of accommodating large-capacity storage is required.As storage capacity increases,additional storage solutions are required.By leveraging deduplication,you can fundamentally solve the cost problem.However,deduplication poses privacy concerns due to the structure itself.In this paper,we point out the privacy infringement problemand propose a new deduplication technique to solve it.In the proposed technique,since the user’s map structure and files are not stored on the server,the file uploader list cannot be obtained through the server’s meta-information analysis,so the user’s privacy is maintained.In addition,the personal identification number(PIN)can be used to solve the file ownership problemand provides advantages such as safety against insider breaches and sniffing attacks.The proposed mechanism required an additional time of approximately 100 ms to add a IDRef to distinguish user-file during typical deduplication,and for smaller file sizes,the time required for additional operations is similar to the operation time,but relatively less time as the file’s capacity grows.

摘要： This study proposes a new generation network based on transformers and guided by the music theory to produce high-quality music work.In this study,the decoding block of the transformer is used to learn the internal information of single-track music,and cross-track transformers are used to learn the information amongst the tracks of different musical instruments.A reward network based on the music theory is proposed,which optimizes the global and local loss objective functions while training and discriminating the network so that the reward network can provide a reliable adjustment method for the generation of the network.The method of combining the reward network and cross entropy loss is used to guide the training of the generator and produce high-quality music work.Compared with other multi-track music generation models,the experimental results verify the validity of the model.

摘要： 隨著數位科技的日新月異,知識傳播和學習方法也在改變。過去以筆紙為主要的教學媒介已隨時間淡去,而使用線上學習資源教、學目標語言變得普遍,尤其是在新冠肺炎疫情大爆發期間。從多媒體學習認知理論(CTML)和全腦學習來看,使用線上學習資源輔助教學對學習效果的影響是正向的,故運用這樣的學習資源輔助華語文教學是有其適用性的。然而,本研究問題之一在於此法對成人學習者的中級華語文學習效益可持續多久?而對不同性別的成人學習者的學習成效影響為何?本研究執行為期一個學期的單組前測後測設計後,發現成人學習者的中級華語文學習成效在使用線上互動學習資源的七週後有顯著效果,但這種效果無法持續到14週後。本實驗研究還發現在使用線上互動學習資源的前後,對不同性別學習成效影響無顯著差異。本研究根據結果歸納出結論,期對後續研究及教學實務有所啟示。

摘要： Nowadays,healthcare applications necessitate maximum volume of medical data to be fed to help the physicians,academicians,pathologists,doctors and other healthcare professionals.Advancements in the domain of Wireless Sensor Networks(WSN)andMultimediaWireless Sensor Networks(MWSN)are tremendous.M-WMSN is an advanced form of conventional Wireless Sensor Networks(WSN)to networks that use multimedia devices.When compared with traditional WSN,the quantity of data transmission in M-WMSN is significantly high due to the presence of multimedia content.Hence,clustering techniques are deployed to achieve low amount of energy utilization.The current research work aims at introducing a new Density Based Clustering(DBC)technique to achieve energy efficiency inWMSN.The DBC technique is mainly employed for data collection in healthcare environment which primarily depends on three input parameters namely remaining energy level,distance,and node centrality.In addition,two static data collector points called Super Cluster Head(SCH)are placed,which collects the data from normal CHs and forwards it to the Base Station(BS)directly.SCH supports multi-hop data transmission that assists in effectively balancing the available energy.Adetailed simulation analysiswas conducted to showcase the superior performance of DBC technique and the results were examined under diverse aspects.The simulation outcomes concluded that the proposed DBC technique improved the network lifetime to a maximum of 16,500 rounds,which is significantly higher compared to existing methods.

摘要： The mission to collect significant and valuable objects and to preserve them in a specially dedicated place,assumes various and different characteristics over the centuries.Nowadays the museum,from a privileged place of conservation and exhibition,is increasingly establishing itself as a powerful medium of social communication and commercial and tourist enhancement.

摘要： Multimedia+ PPLB(practice problem basic learning)是指多媒体+基于实际问题为导向的学习的意思,而在本文主要强调的是在课堂上用多媒体教学,《数据结构》有些部分的理论性很强,需要学生有较好的自主学习能力和较活跃的思维,因此,光靠传统的粉笔+黑板+教师来解决一系列问题似乎已经很难,选用多媒体教学就能解决这部分的问题.

摘要： Phenomenon: Nowadays, with rapidly developing in medical laboratory science(MLS), new concepts, knowledge and technologies are constantly emerging, which requires medical students to continuously learn to grasp the new development trend and the latest research progress. To enable the students to learn and make use of scientific knowledge better, the Special English Curriculum for MLS has been set up, which is very important to non-English-speaking students. However, there are many problems in the course of teaching, so the improved teaching quality of the curriculum is in demand. Approach: In this paper these problems are described and the corresponding advices are proposed from the perspectives of staff room, teachers and students, which are supposed to develop the curriculum for education of the medical laboratory scientists. Findings: To improve the teaching quality of the Special English Curriculum for MLS, the textbook should be appropriately selected or compiled, the novel teaching methods can be applied, and the modern multimedia teaching materials can be adopted.The teachers of the curriculum should be proficient in professional knowledge, English as well as the systematic and scientific teaching methods. The students need to have the courage and determination to overcome the difficulties when they learn the curriculum, and the students who have not did well in their lessons should learn to study by themselves. Insights: The Special English Curriculum for MLS is very important to non-English-speaking students and is kind of difficult for them, the staff room, teachers and students should adjust themselves to teach and learn the curriculum better.

摘要： The information work in the hospital is very complicated. The amount of data is huge, and the forms are various. It is very troublesome to organize and find the data you need. In order to solve the problem, which often appears in the process of analyzing medical case and data, we use Labview2017 to design the corresponding multimedia data calling system for the purpose of rapid searching and effective extraction. This program, which greatly improves work efficiency, can realize fast searching multimedia data in the folder. Since we use of this type of system, the work efficiency has been greatly improved, and the burden on the staff has been greatly reduced.

摘要： By using computer multimedia and database technology to build the animation appreciation auxiliary system (AACAS), we classify the classical animation works according to types, categorize the appreciation main points and define the attribute, and input the corresponding information into the relevant database in real time so as to realize the logical connection of massive animation resources, and make appreciation information be able to realize free storage, rapid retrieval and easy for calling. In addition, the horizontal comparison of multiple works and the vertical comparison of the same work can be realized. This will significantly change the past inefficient situation of animation appreciation under a single thread, greatly improve the timeliness of the appreciation.
