摘要:
为提高油茶果采摘机器人机器视觉的识别率,该文提出了基于偏好人工免疫网络识别的油茶果多特征融合识别方法。在对油茶果图像进行处理的基础上,提取待识别目标区域的颜色特征、形态特征、纹理特征进行聚类,并提取典型油茶果多特征作为偏好抗体,使多特征参数在偏好免疫算法中进行有效融合。仿真试验结果表明,多特征融合的识别方法对油茶果果实的识别率在晴天时达到了90.15%,阴天时达到了93.90%。而时间复杂度基本不变,取得了较好的识别效果,该研究可为下一步油茶果采摘机器人智能采摘提供参考。

摘要:
针对经典人工免疫网络(aiNet)及改进算法中存在的运算时间长、结构复杂等问题,提出了一种改进的核聚类近邻人工免疫网络算法(KN-aiNet)。算法在aiNet的改进算法——近邻aiNet结构的基础上,以抗体数据为核心利用量子能级思想聚类,并重定义了生成抗体策略,采用区域生长法搜索拥挤距离,采用基于核函数的亲和度等方法来提高算法的聚类效果和降低算法的运算时间。聚类实验结果表明,KN-aiNet算法的聚类准确率较经典aiNet算法及近邻aiNet算法分别提高了11.53%和4.56%,而算法的运算时间较经典aiNet算法及近邻ai-Net算法分别下降了0.503 s和0.823 s。

摘要:
当鼠标上下盖两个塑料件同时一模注塑成形时,容易产生填充不平衡等缺陷,为了获得良好的鼠标塑件质量,需要对其浇注系统进行优化。用MOLDFLOW先对鼠标的盖面网格进行划分,创建原始浇注系统,进行填充分析并显示结果,从而对原始浇注系统进行优化。通过多次迭代达到收敛要求后,浇口选用堆切式,并确定浇注系统各浇口的具体尺寸。通过优化后对流道进行平衡分析,结果显示充填时间和充填压力均可满足要求,从而说明MOLDFLOW模拟设计鼠标浇注系统可行。

摘要:
The microencapsulated phase change material (PCM) slurry is a kind of mixture with the PCM microcapsule particles and water. The actual PCM in the microcapsule is composed of several kinds of paraffin waxes (mainly nonadecane), and the membrane is a type of melamine resin. This study is focused on preparation, characterization, and thermal properties of the microencapsulated (PCM) slurry. The microencapsulated PCM particles are prepared by in-situ polymerization method. Four different levels of mass concentration C<inf>m</inf> of the PCM will be used such as C<inf>m</inf>=10%, 20%, 30% and 40%, respectively. The diameter of the particles is distributed in the range of 0μm∼4.5μm, and most (61%) of them occur in the range of 0.5μm∼1.5μm. The average volumetric diameter of the PCM microcapsule particle is about 0.78μm. And the average membrane thickness is about 11nm. Thermal properties of the microencapsulated PCM slurry are determined using differential scanning calorimeter (DSC). From DSC analysis, the melting and freezing temperatures and the latent heats of C<inf>m</inf>=30% are measured as 38°C and 25°C, and 37.9 kJ/kg, respectively. The rheological properties are measured by a rotating cylinder type of rheometer, which the slurry shows the pseudo plastic non-Newtonian fluid behavior with the power-law fluid index n. ©(2011) Trans Tech Publications, Switzerland.

摘要:
A numerical investigation on natural convection heat transfer in a 2-dimensional enclosure heated from below has been conducted with mieroencapsulated phase change material (PCM) slurries. The microencapsulated PCM slurry exhibits pseudoplastic non-Newtonian fluid behavior and has a peak value in the specific heat capacity. The viscosity of the slurry is assumed to follow the Ostwald-de Wade power law fluid model with the power-law index n and the consistency coefficient K. Both dynamic and heat transfer characteristics arc discussed on Rayleigh-Benard natural convection. Characteristics on natural convection heat transfer have been numerically investigated for different value of the width-height aspect ratio of the enclosure. According to the comparison of the two kinds of fluid with PCM and without PCM, the start of natural convection is earlier for the fluid with PCM.

摘要:
This experiment on natural convection heat transfer with the PCM microcapsule slurry for a solid phase state of the PCM were performed at a horizontal rectangular enclosure heating from below and cooling from top. in the present study, important parameters affecting the natural convection heat transfer of the slurry with the PCM were taken into account such as the mass concentration of the PCM microencapsulated into the slurry, the temperature difference between heating plate and cooling plate, the Rayleigh number Ra and the aspect ratio (width/height) of the horizontal rectangular enclosure. The heat transfer characteristics of the PCM microcapsule slurry on natural convection were concluded from predicted conditions simplified by classifying the temperature ranges into three sub-regions, in which the PCM in the slurry was in only solid phase state, phase change state or solid-liquid coexistence state and only liquid phase state of the PCM in the microcapsule, respectively. The upper cooling plate was fixed at a constant temperature in each region, and the lower heating plate temperature was varied by carefully adjusting the electric power input of an electric plate heater. and experiment was done under the thermal steady condition in the PCM microcapsule slurry. Emphasis was given on phase changing temperature range, and experiments had been performed for four kinds of enclosures with various heights. ©(2011) Trans Tech Publications.

摘要:
油茶作为中国的特产,其深加工具有重要的现实意义。测定了油茶蒲水份含量75%左右,油茶籽的水份含量56%左右,油茶果的比热容为2.1~2.5J/g℃。探讨了在微波作用下,油茶蒲裂纹的主要形式有十字型、近1200分开型等,并计算了其临界断裂强度因子与刚度的关系。理论和实践证明,自然形状导致油茶蒲裂纹的位置是在油茶籽最凸起处,因为纤维组织最薄弱,微波作用下油茶果的最初裂开点是其自然采摘最下端。
