A generalized cycle life model of rechargeable Li-ion batteries

A generalized first principles based charge-discharge model to simulate the cycle life behavior of rechargeable Li-ion batteries has been developed. The model is based on loss of the active lithium ions due to the electrochemical parasitic reaction and rise of the anode film resistance. The effect of parameters such as depth of discharge (DOD), end of charge voltage (EOCV) and overvoltage of the parasitic reaction on the cycle life behavior has been quantitatively analyzed. The experimental results obtained at charge rate of 1 C, discharge rate of 0.5 C, EOCV of 4.0 V and DOD of 0.4 were used to validate the cycle life model. Good agreement between the simulations and the experiments has been achieved up to 1968 cycles. Simulation of a battery subjected to multiple cycling regimes has also been demonstrated.

Bare necessities: the argument for a ‘revenge porn’ exception in Section 230 immunity

‘Revenge porn’ is the online posting of nude or sexually explicit photographs or videos of a former lover without his or her consent. Despite the malicious intent behind revenge porn, victims are provided with little to no relief due to Section 230 of the Federal Communications Decency Act, also known as the ‘Good Samaritan’ provisions. Section 230 unambiguously provides blanket immunity for website operators and Internet service providers that feature user-generated content, including revenge porn.

In Section 1, I discuss the purpose of Section 230 of the Communication Decency Act. In Section 2, I analyze the legal impact of the blanket immunity established in Section 230. In Section 3, I examine the potential remedies already in existence for revenge porn victims and highlight their inadequacies. In Section 4, I argue Congress should create a narrow exception to Section 230 immunity specifically geared toward revenge porn. The exception would establish a definition of revenge porn, which would prevent over-deterrence. Additionally, the exception would institute a takedown procedure similar to the process found in the Digital Millennium Copyright Act. In creating a narrow exception, the spirit of Section 230 will remain while also providing adequate legal relief for victims of revenge porn.     

《第一次的亲密接触》变异修辞分析

蔡智恒的语言具有浓厚的变异修辞特点,而《第一次的亲密接触》更是用口语对话的形式将这种特点发挥到淋漓尽致。其变异修辞在语音层面上表现为谐音变异;词汇层面主要表现为词语分拆、抽换语素、曲解语义、语义偏离、语体变异、色彩变异、语域变异、超常组词、方言夹用、简单符号变异;语法层面上表现为超常搭配、词类活用。     

基于预测的最长队列优先调度算法

提出了一个基于预测的最长队列优先(PLQF)调度算法,该算法不仅考虑队列当前长度,还考虑了即将到来的流量信息,根据这一信息,资源被分配给最可能发生溢出的用户,通过预先调整队列长度以满足即将到来的流量,降低了丢包率(CLR),同时提高了缓存的利用率。理论分析表明,PLQF算法可以获得比传统LQF算法更低的CLR,仿真结果证实了PLQF算法的CLR只有传统LQF算法的10%~60%。

Reading electronic books as a support for vocabulary,story comprehension and word reading in kindergarten and first grade

The effect of reading an electronic storybook (e-book) on Israeli children’s language and literacy was examined in kindergarten children (N = 40; age 5:2–6:3) compared to first graders (N = 50; age 6:3–7:4). The children in each age group were randomly assigned to two groups: an intervention group which read the e-book five times and a control group which was afforded the regular school program. Pre- and post-tests included vocabulary and word reading measures. Post-tests included story comprehension and production. Children who read the e-book exhibited significant progress in word meaning and word reading compared to the control group. Kindergarten children progressed in word reading more significantly than first graders across treatment groups. This could be explained by the ceiling effect of the first graders’ word reading level which did not leave much room for progress in this skill compared to the kindergarten children. No interaction was found between age and treatment groups. Kindergarten children exhibited a good level of story comprehension, similar to first graders, although their story production was lower. Implications for future research and education are discussed.
