The Study of the Effect of "The Process Writing Based on Reading-writing Portfolios" on Students'Writing Ability

In order to deal with the problem that exists in current teaching of English writing,this thesis aims to explore a new process writing approach which combines process-based approach with portfolios assessment.

Thoughts and Practices on Cultivating College Students’English Writing Ability

Writing is one of the difficulties in English teaching,and it is a measure of students’mastery of English words,words and sentences.However,students generally find English writing difficult.Therefore,cultivating students’English writing ability is an important topic in current English teaching.There are various ways of cultivating writing ability,which can be summed up as follows:leading students to learn by themselves,cultivating students’ability to apply knowledge comprehensively,improving teachers’classroom language artistry,and emphasizing students’hard work in basic skills.

On the Relationship between Iranian EFL Students’ Writing Strategies and Writing Ability

This study aimed at investigating the relationship between writing strategies,and writing ability of Iranian EFL students.The participants were 120 students learming English in the Iranian EFL context.Data were gathered by means of a writing strategies questionnaire and an IELTS writing task.The results of Pearson correlation test revealed that there was a statistically significant relationship between writing strategies,and writing abilties of the participants.The results have some implications for teaching writing in the EFL context.

Process Tolerant and Power Efficient SRAM Cell for Internet of Things Applications

The use of Internet of Things(IoT)applications become dominant in many systems.Its on-chip data processing and computations are also increasing consistently.The battery enabled and low leakage memory system at subthreshold regime is a critical requirement for these IoT applications.The cache memory designed on Static Random-Access Memory(SRAM)cell with features such as low power,high speed,and process tolerance are highly important for the IoT memory system.Therefore,a process tolerant SRAM cell with low power,improved delay and better stability is presented in this research paper.The proposed cell comprises 11 transistors designed with symmetric approach for write operations and single ended circuit for read operations that exhibits an average dynamic power saving of 43.55%and 47.75%for write and 35.59%and 36.56%for read operations compared to 6 T and 8 T SRAM cells.The cell shows an improved write delay of 26.46%and 37.16%over 6 T and 8T and read delay is lowered by 50.64%and 72.90%against 6 T and 10 T cells.The symmetric design used in core latch to improve the write noise margin(WNM)by 17.78%and 6.67%whereas the single ended separate read circuit improves the Read Static Noise Margin(RSNM)by 1.88x and 0.33x compared to 6 T and 8T cells.The read power delay product and write power delay product are lower by 1.94x,1.39x and 0.17x,2.02x than 6 T and 8 T cells respectively.The lower variability from 5000 samples validates the robustness of the proposed cell.The simulations are carried out in Cadence virtuoso simulator tool with Generic Process Design Kit(GPDK)45 nm technology file in this work.

Variation tolerant and stability simulation of low power SRAM cell analysis using FGMOS

With technology scaling,stability,power dissipation,and device variability,the impact of process,voltage and temperature(PVT)variations has become dominant for static random access memory(SRAM)analysis for productivity and failure.In this paper,ten-transistors(10T)and low power eight-transistors SRAM cells are redesigned using floating-gate MOS transistors(FGMOS).Power centric parameters viz.read power,write power,hold power and delay are the performance analysis metrics.Further,the stochastic parameter variation to study the variability tolerance of the redesigned cell,PVT variations and Monte Carlo simulations have been carried out for 10T FGMOS SRAM cell.Stability has been illustrated with the conventional butterfly method giving read static noise margin(RSNM)and write static noise margin(WSNM)metrics for read stability and write ability,respectively.A comparative analysis with standard six-transistor SRAM cell is carried out.HSPICE simulative analysis has been carried out for 32 nm technology node.The redesigned FGMOS SRAM cells provide improved performance.Also,these are robust and reliability efficient with comparable stability.
