In this paper, we present a new piezoelectrically actuated valveless micropump for the drug delivery system. A simple fabrication process is based on the deep reactive ion-etching (DRIE), glass etching and the anodical bond. The diffuser/nozzle element has the divergence angle of 9.4deg, the width of 0.1 mm for the narrowest part and the length of 1.1 mm. The pressure loss coefficient of the diffuser/nozzle element is analytically studied using the fluid mechanics method. In order to analyze the relationship between the behavior of the micropump membrane and the actuating frequency, the numerical simulation is accomplished by using the ANSYS software. Furthermore, the influences of piezoelectric actuator dimensions and material properties on the natural frequency are also studied to understand the characteristics of the actuator

Alpha-particle-immuno-therapy is a new approach for the treatment of cancer. To produce the required radioisotope actinium (Ac-225) and thus enable the new therapy, an automated manufacturing plant needs to be developed. A striking characteristic of this project is the usage of the long-lived radioisotope radium (Ra-226) as source of the production, meaning that from the very beginning, radioactive material has to be handled. Aside from safety aspects, other challenges exist, such as space limitations, unknown processes and the non-existence of testing possibilities. These requirements demand for adequate technical solutions to realize the aimed manufacturing plant based on a target carrier. In particular, the second part of the production line, the disassembly of the target carrier, requires an innovative approach. Thus a multilevel automation concept was developed: The disassembly operations take place at different levels to deal with limited space requirements. A core element of the concept is a mobile platform for vertical movements where the target is fixed, thus enabling the operation of the process steps for the target with restricted mobility. Further benefits are a significant increase in flexibility, a reduction of complexity and the availability of high forces, in combination with precise and controlled movements. Critical process steps such as the rinsing of the target components to extract the products can be done simultaneously

This paper proposes a new relaxation-based circuit simulation algorithm called backward-traversing waveform relaxation (BTWR). BTWR employs a brand new strategy to simulate: it simulates by performing depth-first search in the signal flow graph of simulated circuits. Major advantage of BTWR is the ability to flexibly schedule subcircuits for calculating according to subcircuits' converging situations, which enables BTWR to act robustly as well as efficiently in dealing with various types of circuits. The simulation on demand (SOD) function is also constructed in BTWR. All proposed methods have been implemented and tested by simulating various circuits

Near infrared reflectance spectroscopy (NIRS) appears to be a rapid and convenient non-destructive technique that can measure the quality and compositional attributes of many substances. This paper assesses the ability of NIR reflectance spectroscopy to estimate the pH values of bayberry juice. Spectra were collected from 76 juice samples and data was expressed as absorbance, the logarithm of the reciprocal of reflectance (log 1/R). The absorbance data was subsequently compressed using wavelet transformation. Three models to predict the acidity in bayberry juice were constructed. A prediction model based on principle component analysis-multiple linear regression-back propagation (PCA-MLR-BP) was found to be superior (r=0.934, RMSEP=0.263) to models based on PCA-BP and MLR-BP

Performance evaluation and schedule optimization of cluster tools is challenging, especially when the process times are with uncertainty. In this paper, the critical path method (CPM) is used to analyze the throughput of multi-cluster tools with fixed action sequence. Slacks of non-critical path actions are studied and integrated to find the average cycle time of the cluster tool. A thin film tool from Novellus is used as an example to explain this methodology

A manufacturing system is typically a shared resource system whose components never have unlimited capacities. In manufacturing system design, a major objective is to achieve a system which is free from capacity overflow. In this paper, a method is proposed for analysing if a system possesses this property. The method is based on augmented marked graphs. By modelling a manufacturing system as an augmented marked graph, we can analyse the possibility of capacity overflow using the properties of bounded augmented marked graphs

In this paper, the techniques of an experiment-based brush footprint acquisition method and a genetic algorithm (GA)-based brush stroke generation scheme are combined. The combined method is applied to replicating a given Chinese character. Additionally, a new method to come up with the brush stroke skeleton to facilitate Bezier representation of the brush stroke, rather than the thinning algorithm in previous works, is also incorporated. Actual experiments were conducted to demonstrate the performance of combined method and to compare with the original character. The present paper is part of an endeavour to attempt replicating the works of famous past calligraphers.

Majority of current devices, crutches, canes and walkers, used to help people with knee problems are passive orthotic devices. In rehabilitation for knee injuries and aiding elderly people with knee joint arthritis, it is often desired to reduce the load at the knee to help the healing process as well as to relieve pain. However, the use of passive devices may cause inconveniences in daily routines and difficulties in mobility for the user. Current robotics orthotic devices have advantages over passive devices because it is capable of aiding the knee; reduce the knee stress without affecting the mobility of the user. The objective of this work is aimed to study and develop a portable active orthotic device that can be used for rehabilitative purposes. This device is used in reducing the body weight of the user acting on the knee. The first prototype is designed and constructed to carry out tests on the effectiveness of the device. An encoder was also employed to detect the movement of the user, as a reference to drive the actuator. A mechatronic module was used as the controlling system of the device. The experimental results were analyzed for the effectiveness of the prototype device

The mode of bio-fermentation control selected has a direct impact on fermentation trajectory accuracy, production quality, and yield. A high performance bio-fermentation control system design that combines a set of sensors and actuators is presented. The bio-fermentation control system uses an embedded microprocessor controller, the SAMSUNG's S3C44BOX microprocessor system. The main fermentation process parameters and the control system hardware construction are discussed in detail. When compared with the single chip microcomputer and personal computer controller, the fermentation control system employing embedded microprocessors promises the advantages of better holistic performance, and higher yield efficiency.
