1. Yang, An-Yun. The drug fibers for accurate stepping near field electrospinning application.

Degree: Master, Mechanical and Electro-Mechanical Engineering, 2016, NSYSU

In this research, the electrospinning solution injection rate was controlled by micro stepping control on stepper motor, so that the mixed solution of polycaprolactone (PCL) and natural anti-inflammatory drugs in the direct writing system of near field electrospinning (DWs-NFES) can use the process parameters and controllable injection rate by uniform experimental design to produce stable fibrous support structure, which can help wound healing and achieve rapid biological wound healing. This study used DWs-NFES and combined with process parameters of uniform experimental design calculus. In the condition of the drug-loaded fiber PCL/F101 and ethyl acetate (EA) solution of 16.77~32.79 wt% and 43.72Ë~84.68Ë contact angle, by injection rate of 0.001~0.016 ml/hr and the needle of inner diameter of 0.05~0.35 mm, under 0.82~11.25 MV/m high electric field has forced the solution to break through surface tension thus forming Taylor cone. Furthermore, through the X-Y axis direction control and moving speed of 900~1200 mm/min, the Taylor cone jet form deposited reticular. Finally, by DWs-NFES process parameters of uniform experimental design can find that at PCL/F101 solution at 18.91 wt%, needleâs inner diameter at 0.25 mm, injection rate at 0.00571 ml/hr, electric field at 2.18 MV/m and platform moving speed at 936.6 mm/min can reach 0.89 μm drug monofilament diameter. When stepper motor control the injection timing and speed of electrospinning by micro stepping control can reach 0.68 μm drug monofilament diameter. Drug monofilament deposited mesh structure 60 x 60 mm2 under the control of X-Y axis direction and rate of movement, compared with the gel and injured group in 14 days of wound healing experiment, the results of area under curve (AUC) find the drug monofilament is higher than the gel and injured group about 3.67 times, due to the deposited mesh structure upgrade the fiber density in unit area.It proves when the electrospinning solution injection rate was controlled by micro stepping control on stepper motor combined with process parameters of uniform experimental design calculus, the diameter of drug monofilament reduced and upgrade the fiber density in unit area to obtain the better ability of wound healing.

2. Sun, Yen-Po. Ultra-wide view of light guide module for solar concentration.

Degree: Master, Mechanical and Electro-Mechanical Engineering, 2016, NSYSU

The general solar concentrators are designed with a small acceptance angles (θmaxâ¦Â±1°). Therefore, these concentrators would be set up on a solar tracker to improve the alignment tolerance, but they also increase the cost. In this paper, the ultra-wide view concentrator (UWC) is designed for collecting solar light rays in various incident angles, and then focuses the solar light on a focal plane without precise solar tracking system. The UWC that comprises a parabolic reflector, compound parabolic concentrators (CPCs) and free-form collimators (FCs). In addition, CPC and FC are integrated to form the ultra-wide view of concentrating unit (UWCU). The UWCUs could array to become the secondary module, and put them onto the parabolic reflector primary module to become the UWC finally. Then the performances and analysis of three optical components and UWC were confirmed respectively, including design another shape of CPC named ACPC to increase the fill rate, design a new type of FC named optimized FC to increase the collimation, and design two types of parabolic reflector named Single parabolic reflector and Dual parabolic reflector to compare with them which is suitable for assembling to UWCUs. Finally, the prototype was fabricated by 3D printer and Precision Machining. Simulation results show that in all kinds of secondary and primary module, choose ACPC to array onto the Single parabolic reflector to become the best UWC. The results of UWCU show that the optical efficiency of 50~80% is under acceptance angle â¦Â± 10°. The UWC was achieved under acceptance angle in the range of θmaxâ¦Â±10°. Finally, when under 1 kW/m2 sunlight, this UWC would have the best performance between 11:20~12:40 a day without solar tracking system, and the UWC would receive 3.97W (the efficiency is 70%) on the plane receiver.

3. Lin, Gu-Xuan. Study of Modified Comb Magnetic Structure in High Efficient Synchronous Permanent Magnet Dynamotor.

Degree: Master, Mechanical and Electro-Mechanical Engineering, 2016, NSYSU

In the study, a new design of synchronous permanent magnet dynamotor (SPMD) with comb magnetic resistance route (CMR) structure was proposed to enhance the efficiency of generator by changing the magnetic route structure. The CMR structure was inducted the change in magnetic flux and dispersed into the staggered NS poles to affect the inner windings and led to stable sinusoidal back EMF. The main design was gone through changing the distance between the soft, width, and thickness, and numbers of poles in the CMR structure to change the magnetic field. The Taguchi method was used to make the parameter design and regression analysis. The power generation voltage was studied under different circumstances by using ANSYS MAXWELL electromagnetic simulation. The open-circuit voltage of the entity generating device was 100 mV and the voltage of simulation was 148.75 mV under 160 rpm. It verified the correctness of the simulation. The results show that the open-circuit voltage of this new SPMD with the CMR structure width at 3.65 mm, the thickness at 3.5 mm, the radius of notch at 3 mm, 28 poles, and cast iron as the soft material was 67.88 V. With a load of 100 ohms, the maximum voltage was 42.9 V and the power was 18.45 W. The new SPMD has more stable waveform, higher power generation and performance at the same speed.
