A light-emitting diode (LED) street lamp is applicable for street lighting. The LED street lamp includes a casing, an LED module, and a heat dissipation module. The LED module and the heat dissipation module are arranged inside the casing. The LED module includes a frame, a circuit board carrying a plurality of LEDs, and a light regulation mechanism. The frame and the circuit board are set opposing each other with the light regulation mechanism arranged therebetween to interfere with emission light from the LEDs. The emission light, after being interfered with, is projected outside the casing to realize lighting. The heat dissipation module is in physical engagement with the LED module to remove heat generated by the LEDs. As such, the LED street lamp is provided with a broader range of illumination angle and more uniform brightness, so that the same LED street lamp is applicable to various sites and the heat generated by the LEDs can be efficiently dissipated.

An etching process of a metal layer of a display panel is provided. First, a substrate with at least one display panel region, a testing device region, and a non-device region is provided. Then, a metal layer is formed over the substrate to cover the display panel region, the testing device region, and the non-device region. Next, a mask is formed on the metal layer to expose a portion of the metal layer. The area of the metal layer exposed by the mask substantially occupies 70%˜88% of the total area of the metal layer. Thereafter, a wet etching process is performed to remove the metal layer exposed by the mask.

A method for making a series of nanoscale microstructures, including helical microstructures and cylindrical microstrustures. This method includes the steps of: (1) forming a chiral block copolymer containing a plurality of chiral first polymer blocks and a second polymer blocks wherein the chiral first polymer blocks have a volume fraction ranging from 20 to 49%; (2) causing a phase separation in the chiral block copolymer. In a preferred embodiment, the chiral block copolymer is poly(styrene)-poly(L-lactide) (PS-PLLA) chiral block copolymer, and the copolymerization process is a living copolymerization process which includes the following steps: (a) mixing styrene with BPO and 4-OH-TEMPO to form 4-hydroxy-TEMPO-terminated polystyrene; and (2) mixing the 4-hydroxy-TEMPO-terminated polystyrene with [η3-EDBP)Li2]2[(η3-nBu)Li(0.5Et2O)]2 and L-lactide in an organic solvent preferably CH2Cl2 to form the poly(styrene)-poly(L-lactide) chiral block copolymer. Transmission electron microscopy (TEM) and small X-ray scattering (SAXS) studies show that when the volume fraction of poly(L-lactide) is about 35–37%, nanoscale helices with a pitch of 43.8 nanometers and a diameter of 34.4 nanometers were observed.

摘要:
A method for processing natural language Chinese sentences can transform a Chinese sentence into a Triple representation using shallow parsing techniques. The method is concerned with parsing Chinese sentences by employing lexical and syntactical information to extract more prominent entities in a Chinese sentence, and the sentence is then transformed into a Triple representation by employing the Triple rules referring to elemental Chinese syntax—SVO (subject, verb, and object in order). The lexical and syntactical information in our method is referring a lexicon possessed of part-of-speech (POS) information and phrase-level syntax in Chinese respectively. The Triple representation consists of three elements which are agent, predicate, and patient in a sentence.

摘要:
In a capacitance sensing analog circuit of a touch panel sensing circuit, by raising a magnitude of a current flowing through a sensing capacitor to form an amplified sensing capacitance, while sensing the amplified sensing capacitance with the aid of pulse width modulation signals, higher resolution of the original sensing capacitance may thus be achieved. Besides, by using a self-calibrating capacitance sensing circuit on the touch panel sensing circuit, linear errors and DC errors of an output signal of the capacitance sensing analog circuit may be filtered off, and thereby resolution of a capacitance amplifying ratio may be effectively raised so as to relieve errors within the capacitance amplifying ratio caused by noises.
