略论中国传统合院住宅形式的固化与沿用

合院式住宅是中国人沿用了二千多年的典型形制，除了其能满足采光、通风的要求和建造相对简化外，中国传统社会早期的中霤祭祀和以五行为基本元素的统括万物的宇宙模式对于中国式合院住宅的固化与沿用，也起了不可忽视的作用。     

Workflow performance analysis and simulation based on multidimensional workflow net

Workflow model performance analysis plays an important role in the research of workflow techniques and efficient implementation of workflow management. Instances dwelling times (IDT) which consist of waiting times and handle times in a workflow model is a key performance analysis goal. In a workflow model the instances which act as customers and the resources which act as servers form a queuing network. Multidimensional workflow net (MWF-net) includes multiple timing workflow nets (TWF-nets) and the organization and resource information. This paper uses queuing theory and MWF-net to discuss mean value and probability distribution density function (PDDF) of IDT. It is assumed that the instances arrive with exponentially distributed inter-arrival times and the resources handle instances within exponentially distributed times or within constant times. First of all, the mean value and PDDF of IDT in each activity is calculated. Then the mean value and PDDF of IDT in each control structure of a workflow model is computed. According to the above results a method is proposed for computing the mean value and PDDF of IDT in a workflow model. Finally an example is used to show that the proposed method can be effectively utilized in practice.     

一种基于基带变标的非均匀扫描TOPSAR成像算法

由于传统TOPSAR具有均匀的天线扫描速度,在扫描范围较大的情况下,靠近图像边缘的目标被天线波束照射的时间较短,图像中心部分的目标照射时间较长,从而导致了TOPSAR图像分辨率不一致,本文针对上述问题提出一种非匀速扫描的TOPSAR成像方法,根据TOPSAR扫描几何模型得到图像分辨率与扫描速度的数学关系,通过控制天线的旋转角速度,使场景中方位向不同位置的点目标积累时间相同,从而保证了所得SAR图像具有相同的方位分辨率。仿真结果和分析表明,该方法有效地保证了TOPSAR图像分辨率的一致性。

Energy efficient demand controlled ventilation in single family houses

This paper presents a strategy for a simple demand controlled ventilation system for single family houses where all sensors and controls are located in the air handling unit. The strategy is based on sensing CO₂-concentration and moisture content in the outdoor air and exhaust air. The CO₂-concentration is used to ensure adequate ventilation during occupancy and the moisture content is used to ensure adequate removal of moisture produced in the house. The ventilation rate can be switched between two flow rates: a high rate and a low rate. The high flow rate is based on existing requirements in the Danish building regulations and the low flow rate is based on minimum requirements in indoor air quality standards. Measurements were performed on an existing single family house where the controls were installed on the existing mechanical ventilation system. The results showed that the ventilation can be reduced to the low rate 37% of the time without significant changes in the CO₂-concentration and moisture level in the house. In theory this gives a 35% saving on electric energy for fans.
