A new plug-in for the creation of OPC servers based on EcosimPro© simulation software

OPC (Ole for Process Control) is an Interoperability Standard that is being extensively used at industry because it facilitates integration and communication between heterogeneous subsystems. From the point of view of the simulation software, OPC support is a bonus that enhances the communication capability between simulation models. In this paper, we describe the development issues for incorporating OPC support into the EcosimPro© modelling and simulation software. The result of this project is a commercially available plug-in that transforms an EcosimPro© model into an OPC server ready to exchange data with other subsystems. Possibilities of the new functionality of the tool are also discussed.     

Implicit Fields© - MOCAPE Shenzhen PRC

During late 2007, guest-editor George L Legendre of IJP Corporation and Max Kahlen of Dyvik & Kahlen, Architecture, joined forces to develop a competition design for the Museum of Contemporary Art and Planning Exhibition (MOCAPE); in Shenzhen. One of the great challenges of the brief was the subdivision of a great expanse of programmed spaces. In order to tackle this, they created the design concept of ‘natural erosion’ for which they developed their own parametric surface model, the implicit field^©.

基于MSP430单片机的智能充电器设计

针对铅酸蓄电池充电器,在充电过程中,不能对电流、电压实时性监测,交互能力和控制能力弱等问题,设计了一种基于MSP430F169单片机能够实时显示电流、电压大小,并且可以调节电流大小的智能充电器。这种充电器具有硬件电路简单,功耗低等特点。     

基于高通量培养的胶球藻C-169生物量和油脂积累能力的快速评价

本研究利用CO_2培养箱内48孔板振荡光照培养专利设计的微藻高通量培养体系,结合细胞组学技术,系统评价了氮源和盐度梯度下胶球藻C-169细胞的生长速率、生物量浓度和油脂积累能力。结果表明,该培养体系的均一性和稳定性良好,可实现微藻的高通量及多处理培养。富氮培养基可显著提高胶球藻C-169的细胞生长速率和生物量浓度,缺氮培养基显著驱动了细胞积累中性脂。在含1/4氮的培养基中藻细胞的生物量浓度是4倍氮培养基中的25%,而中性脂含量(平均荧光强度表示)则高达后者的16倍以上。在0~15‰盐度范围内胶球藻C-169的生长状况良好且无显著差异(p0.05),15‰以上盐度藻细胞生长受到明显抑制。10‰盐度下中性脂含量(以平均荧光强度表示)显著高于所有其他组(p0.05),说明该盐度有利于驱动细胞积累中性脂。     

A cooking quality parameter as an indicator of adulteration of Basmati rice

Among various cooking quality parameters, differential length/breadth ratio has been found to be a reliable indicator of adulteration of Basmati rice, with Improved Sabarmati, Pusa-169, PR-106, Kali-much, Lakra and Parimal, which are the rice varieties used frequently for adulteration. A minimum value of length/breadth ratio of 3.92±0.09 to 4.09±0.09 was found to be indicative of pure Basmati.     

补充CO2提高胶球藻C-169生物量和脂肪酸产率的研究

本研究在Basal和BBM培养基中补充2%CO2或空气(0.04%CO2)光自养培养胶球藻(Coccomyxa subellipsoidea)C-169,系统比较了细胞比生长速率、生物量干重、总脂肪酸含量和产率以及中性脂含量的差异。研究表明,与空气培养相比,在Basal和BBM培养基中补充2%CO2可分别显著提高细胞的比生长速率2.6倍和2.3倍。培养13 d后,Basal培养基中补充2%CO2可获得最高生物量干重达4.67 g/L,显著高于所有其他组(p0.05);而BBM培养基中补充2%CO2可获得最高总脂肪酸含量达37.53%干重,是通入空气时的5倍,脂肪酸产率更是高达77.49 mg/(L·d),同时中性脂含量(以荧光强度表示)显著高于所有其他组(p0.05)。这就说明在Basal培养基中补充CO2有利于细胞生物量的积累;而在BBM培养基中补充CO2更有利于驱动细胞高产脂肪酸和中性脂,其生物量是制备生物柴油的极好原料。

GH169合金的DA处理

用热变形后的直接时效(DA处理)和标准热处理对比试验的方法,对DA处理在GH169合金中的实际应用进行了探讨。结果表明,DA处理确可提高合金的拉伸强度,并大幅度提高光滑持久寿命。但由于塑性指标的降低而导致缺口持久和周期持久寿命的降低,并使疲劳、蠕变交互作用的蠕变损伤加剧。其原因是可能DA处理过程中晶界δ相析出过少,晶界晶内强度配合不良,达不到强韧化的作用。同时指出晶粒细化,并在变形工艺中对位错组态进行控制,使δ相以合理的数量和形态析出,才能获得真正应用的DA GH169合金。
