基于AUKF的可穿戴式设备用锂离子电池SOE在线估计方法

可穿戴式设备(wearable devices,WDs)体积小、工作时间长,在工业监测等领域应用越来越广泛。锂离子电池为WD上电子设备提供能量,其准确的能量状态(state of energy,SOE)在线估算对WDs的电源实时管理与延长设备寿命有重要影响。传统的基于模型的估算方法需要离线获取SOE与开路电压(open circuit voltage,OCV)的关系,实验时间长,不能适应实际工况变化,难以在线实施,本工作提出一种基于开路电压(opencircuit voltage,OCV)在线辨识的可穿戴式设备用锂离子电池SOE在线估算方法。首先基于锂离子电池的一阶RC模型,采用带遗忘因子的递推最小二乘法(forgetting factor recursive least squares,FFRLS)在线辨识电池OCV等参数。分析了WDs运行负载变化特征,构建了WD运行工况和参数辨识工况,并开展锂离子电池实验。结合WDs工作负载特性,研究了开路电压和端电压的关系,在线获得OCV与SOE的关系曲线。采用无迹卡尔曼滤波(adaptive unscented Kalman filter,AUKF)算法实现SOE的在线估计,与传统通过离线实验获得OCVSOE关系的方法进行了对比。研究结果表明,所提的SOE在线估算方法具有较好的精度,并在不同的SOE初始值时具有较好的鲁棒性。

New Restructuring Model for Chinese M&S SOEs:A Case of Executive Holding Major Capital Stock

The reform for Chinese state-owned enterprises (SOEs)during the past twenty years selected several ways which couldn't solve essential problems and improve the performance of the SOEs in China. The reason is that traditional ownership instituton wasn't changed at all,the institution reach an impasse in market system which resulted in the fact that SOEs couldn't get used to keen competition. This paper analyses an ownership restructuring case in which an executive holds major capital stock in a state textile institute restructured and therefore the state ownership was withdrawn from it completely, it expounds the rationality of the model selected and points out that the model is currently a very effective way by which M & S SOEs would withdraw from competitive business field successfully.

How ＂New SOEs＂ Come of Age： Four Decades of China＇s SOE Reform

China＇s complex and twisted journey of SOE reform over the past four decades is an unprecedented transformation in its history and is at the center stage of its economic reforms. Over the past four decades, SOEs transitioned from being affiliates of a planned economy to ＂new SOEs＂ as modern enterprises under the market economic system. This journey can be roughly divided into the following four stages： the reform to expand SOE autonomy during 1978-1993, the reform to create a modern enterprise system during 1993- 2003, the reform to create a new system for the administration of state assets during 2003- 2013, and the new era of classified SOE reform since 2013. After the four stages, China＇s SOE reform has made tremendous achievements, particularly since the 18th CPC National Congress. V~th policy readiness for SOE reform in the new era, reform should be carried out in a comprehensive and systematic manner for different types of SOEs in the future.

Social responsibility and SOE restructuring

Effective Incentive and Discipline Mechanisms for Top manage-ment in SOEs

Key to energize State-Owned-Enterprises (hereinafter SOEs) is to set up effective incentive and discipline mechanisms. First of all, the paper analyses the problems existing in the current incentive and discipline mechanism system in SOEs, including low transparency income and considerable covert income, insider control,corporate governance nominalization and so on; next,the paper explores the causes behind these problems,such as incomplete corporate governance and imperfect market mechanism; finally, the paper proposes a series of solutions from the aspects of incentive mechanism and discipline mechanism.

The Claim that “SOEs Are Inefficient” Is Unfounded

This paper paints out that historical factors and ’high withdrawal barriers’ are to blame for some low indices of SOEs.Supposing SOEs can withdraw freely as non.SOEs do,their indices will not necessarily be lower than the non-SOEs.If we take into account the input of the current period,the efficiency of SOEs is actually higher than that of non-SOEs.The author concludes that the notion that"SOEs are inefficient"is ungrounded and instead that historical factors and ’high withdrawal barriers’ are to blame for some low indices of SOEs.

Effect of Chia Seed on Physicochemical and Sensory Characteristics of Common Carp Restructured as Functional Food

Physicochemical and sensory characteristics of restructured meat of common carp （Cyprinus carpio） fortified with 0-8 g/100 g of chia seed flour （CSF） was evaluated. It had a higher nutritional value （higher fibre content and protein retention] （p 〈 0.05） and better cooking characteristics （higher cooking yield and moisture retention） （p 〈 0.05） than the control. The colour （a＊, b＊） increased; lightness and whiteness index decrease （p 〈 0.05）. Hardness increase （p 〈 0.05） occurred because of CSF addition. Differential scanning calorimetry showed that fibre fortification did not interfere with the thermal transitions of the restructured meat. No significant differences were detected with the preference test scores of 4% or 8% CSF compared with the control. Restructured （4%-8% CSF） had a higher content of fibre and fat, which could be linoleic and linolenic acid, and an increase in the content of protein compared with those of commercial products, among had 1.62 and 2.25 mg AGE/g. Therefore, the restructured properties of common carp were governed by CSF addition.

Restructuring Tilth Layers Can Change the Microbial Community Structure and Affect the Occurrence of Verticillium Wilt in Cotton Field

Restructuring tilth layers(RTL)is a tillage method that exchanges the 0–20 and 20–40 cm soil layers that can be applied during cotton cultivation to increase cotton yield,eliminate weeds and alleviate severe disease,including Verticillium wilt.However,the mechanism by which RTL inhibits Verticillium wilt is unclear.Therefore,we investigated the distribution of microbial communities after rotary tillage(CK)and RTL treatments to identify the reasons for the reduction of Verticillium wilt in cotton fields subjected to RTL.Illumina high-throughput sequencing was used to sequence the bacterial and fungal genes.The disease incidence and severity of Verticillium wilt decreased by 28.57%and 42.64%,respectively,after RTL.Moreover,RTL significantly enhanced bacterial richness and evenness at 20–40 cm and-reduced the differences in fungal evenness and richness between soil depths of 0–20 and 20–40 cm.The number of Verticillium dahliae decreased,while the relative abundance of biocontrol bacteria such as Bacillus and Pseudoxanthomonas increased significantly following RTL.Overall RTL improved bacterial diversity,decreased the number of Verticillium dahliae and increased the relative abundance of biocontrol bacteria,which may have suppressed the occurrence of Verticillium wilt in cotton fields.
