Dynamic Write-Voltage Design and Read-Voltage Optimization for MLC NAND Flash Memory

To mitigate the impact of noise and inter-ference on multi-level-cell(MLC)flash memory with the use of low-density parity-check(LDPC)codes,we propose a dynamic write-voltage design scheme con-sidering the asymmetric property of raw bit error rate(RBER),which can obtain the optimal write voltage by minimizing a cost function.In order to further improve the decoding performance of flash memory,we put forward a low-complexity entropy-based read-voltage optimization scheme,which derives the read voltages by searching for the optimal entropy value via a log-likelihood ratio(LLR)-aware cost function.Simulation results demonstrate the superiority of our proposed dynamic write-voltage design scheme and read-voltage optimization scheme with respect to the existing counterparts.

Security Threats to Business Information Systems Using NFC Read/Write Mode

Radio Frequency IDentification(RFID)and related technologies such as Near Field Communication(NFC)are becoming essential in industrial contexts thanks to their ability to perform contactless data exchange,either device-to-device or tag-to-device.One of the three main operation modes of NFC,called read/write mode,makes use of the latter type of interaction.It is extensively used in business information systems that make use of NFC tags to provide the end-user with augmented information in one of several available NFC data exchange formats,such as plain text,simple URLs or enriched URLs.Using a wide variety of physical form factors,NFC-compatible tags(wireless transponders)are currently available in many locations with applications going from smart posters,contactless tokens,tap-and-go payments or transport ticketing to automated device configuration,patient identification at hospitals or inventory management within supply chains.Most of these applications handle sensitive processes or data.This paper proposes a complete security threat model for the read/write operation mode of NFC used in Next Generation Industrial IoT(Nx-IIoT)contexts.This model,based on a wellknown methodology,STRIDE,allows developers and users to identify NFC applications vulnerabilities or weaknesses,analyze potential threats,propose risk management strategies,and design mitigation mechanisms to mention only some significant examples.

On the Application of Reading-to-Write Approach to English Writing Teaching in Senior Middle School

As one of the four basic skills of language teaching and an aspect of communicative competence,writing seems to be the weakest one among senior school students in China.Most of teachers have had such experiences that although we spend a lot of time marking on the students'writing,but only to find the corrections and comments ignored.The students pay little attention to responses and regard revision of their writing as a punishment.Starting from the perspectives of modern linguistic theory,the pressing demands of the new curriculum,and the practical needs of student development,the study analyses the prevalent misconceptions about writing.The author proposes an assumption of integrating the teaching materials with Reading-to-Write Approach in the senior school writing teaching.To examine the validity of the Approach,about one-year action research is carried out in an ordinary high school,adopting the methodology of literature survey,questionnaire survey,interview,testing and so on.The results of the experiment showed that the approach had a more positive impact on students'writing attitudes and habits than traditional teaching methods.This approach helped them much more in word usage,longer sentences,content,and text structure or development.Besides,the students'compe?tence of interaction and cooperation were enhanced,Therefore,the approach in writing teaching is effective.

Study on the relationship between English reading and writing

Reading and writing are input and output respectively. The relation between reading and writing is closely related. Reading is the preparation for good writing.

Also the way of thinking influences our reading and writing.

An application of Genre-based Teaching Approaches into the teaching of English reading and writing

There are several teaching approaches being used to instruct the reading and writing teaching, such as the product approach, the process approach and the genre approach. In a long period, the product approach and the process approach dominate the field of writing teaching. With the development of genre and genre-analysis theory, we begin to realize that genre-based approach is effective in improving students ’ reading comprehension and writing. Based on the analysis of the theory and on the present situations of college English teaching and personal teaching experience, the genre-based teaching approach is introduced to the writing and reading comprehension teaching.

＂Flipped Class Mode＂ Applied to Reading and Writing Class With WeChat APP

With the development of computer, technology way of language teaching has experienced great changes. In the past, the methods of language teaching mainly focus on the direct method, the grammar-translation, audio-lingual, the structure approach, communicative language teaching, community language learning, task-based language learning, etc. These methods start and develop with the need and application of some theories.
