Weani ng from mechanical ventilation in the in tensive care unit (ICU) is a complex clinical problem and relevant for future organ engineering. Prolonged mechanical ventilation (MV) leads to a range of medical complications that increases length of stay.and costs as well as contributes to morbidity.and even mortality.and long-term quality.of life. The need to reduce MV is both clinical and economical. Artificial intelligence or machine learning (ML) methods are promising opportunities to positively.influence patient outcomes. ML methods have been proposed to enhance clinical decisions processes by.using the large amount of digital information generated in the ICU setting. There is a particular interest in empirical methods (such as ML) to improve management of "difficult-to-wean" patients, due to the associated costs and adverse events associated with this population. A sy.tematic literature search was performed using the OVID, IEEEXplore, PubMed, and Web of Science databases. All publications that included (1) the application of ML to weaning from MV in the ICU and (2) a clinical outcome measurement were reviewed. A checklist to assess the study.quality.of medical ML publications was modified to suit the critical assessment of ML in MV weaning literature. The sy.tematic search identified nine studies that used ML for weaning management from MV in critical care. The weaning management application areas included (1) prediction of successful spontaneous breathing trials (SBTs),(2) prediction of successful extubation,(3) prediction of arterial blood gases, and (4) ventilator setting and oxy.enation-adjustment advisory.sy.tems. Seven of the nine studies scored seven out of eight on the quality.index. The remaining two of the nine studies scored one out of eight on the quality.index. This scoring may. in part, be explained by.the publications' focus on technical novelty. and therefore focusing on issues most important to a technical audience, instead of issues most impor

Gaussian Markov model (GMM) has been widely.used in the area of speaker recognition. It can be considered as a one-state hidden Markov model (HMM) with multiple mixtures. As for the HMM, maximum-likelihood (ML) estimation is considered a good choice of training approach for the GMM-based speaker identification. However it only.considers the likelihood of a single speaker. That is, each speaker model is estimated separately.using its labeled training utterances. To compare the likelihood against those similar speakers and maximizes their likelihood differences, another training algorithm named maximum model distance (MMD) is proposed for GMM in this paper. Experimental results from the TI46-Word and TIMIT database show that it is an attractive alternative for the GMM training.

为使基于产品平台的系列产品更好的满足顾客需求,提出一种基于质量功能展开的方法,可以优化设计可伸缩产品平台。该方法的主要思路是应用质量功能展开技术,建立单个产品的质量屋,确定其最优工程特性值,对每个工程特性进行敏感性分析,并根据所得的工程特性敏感性指标建立优化模型,求得最优的平台工程特性值和非平台工程特性值。优化模型的目标是最大化一个产品族中所有产品变体的顾客满意度的均值,约束主要包括顾客需求和工程特性之间的函数关系以及工程特性之间的自相关函数关系。模型中采用了线性函数形式,并采用回归方法来估计函数中的参数。给出一个工业卡钳的例子来验证所提方法的可行性,案例分析的结果表明,该方法比传统的两阶段方法能获得更好的顾客满意度。

Conservation agriculture has been practised for three decades and has been spread widely. There are many.nomenclatures surrounding conservation agriculture and differ to each other lightly. Conservation agriculture （CA） is a sy.tem approach to soil and water conservation, high crop productivity.and profitability. in one word, it is a sy.tem approach to sustainable agriculture. y.t, because conservation agriculture is a knowledge-intensive and a complex sy.tem to learn and implement, and also because of traditions of intensive cultivation, adoption rates have been low, since to date, only.about seven percent of the world＇s arable and permanent cropland area is farmed under conservation agriculture. The practice and wider extention of conservation agriculture thus requires a deeper understanding of its ecological underpinnings in order to manage its various elements for sustainable intensification, where the aim is to conserve soil and water and improve sustainability.over the long term. This paper described terms related to conservation agriculture, presented the effects of conservation agriculture on soil and water conservation, crop productivity. progress and adoption of CA worldwide, emphasized obstacles and possible way. to increase CA adoption to accelerate sustainable development of China agriculture.

As a support material, zeolite can be used to promote the granulation process due to its high settable property.and the ability.to retain biomass on its surface. The present paper reports on the influence of zeolite addition on the hy.rody.amic behavior of an expanded granular sludge bed reactor（EGSB）. Different models were applied to fit the flow pattern and to compare EGSB hy.rody.amic performance with and without the addition of zeolite. The experimental data fit the tanks in a series model for zeolite bed height of 5 cm and upflow velocity.of 6 m/*** axial dispersion degree（D/uL） was obtained at lower heights of zeolite. The real hy.raulic retention time（HRTr） was increased with both increased zeolite bed height and increased upflow velocity. The short-circuit results for 5 cm of zeolite bed and 6, 8 and 10 m/hr upflow velocity.were 0.3, 0.24 and 0.19 respectively. demonstrating the feasibility.of using zeolite for a proper hy.rody.amic environment to operate the EGSB reactor. The presence of zeolite resulted in the higher percentage values of dead zones, ranging from 12% to 24%.Zeolite addition exerted a positive effect on the hy.rody.amics pattern for this technology.being advantageous for the anaerobic process because of its possible contribution to better biofilm agglomeration, granule formation and substrate-microorganism contact.
