AbstractHigh luminance (brightness) thin-film phosphor materials have potential use in a variety of applications including heads-up, helmet-mounted, and electroluminescent displays, as well as in emerging flat-panel displays based on field emitter technology. Phosphor materials in thin film form offer several advantages over conventional powder phosphor screens. Since the film is nearly fully dense and in intimate contact with the underlying substrate, thin film phosphors transfer heat to the face plate much quicker than conventional, more porous, powder phosphor materials. This allows thin film phosphor screens to be driven at higher power levels, and therefore produce higher luminance, assuming the efficiency of the powder and film are the same. Fully dense phosphor films have smaller surface area, and will outgas less than conventional powder phosphor materials. Thin film phosphors have smaller grain sizes than conventional powder phosphor materials which will provide for smaller spot size, and thus, higher resolution. Furthermore, in applications such as field-emitter displays, powder phosphor particles can be physically dislodged from the screen due to the high electric fields produced by the large potential difference between the anode screen and gate electrode (or cathode), or dislodged by arcing which may occur if a powder particle protrudes significantly above the screen surface. Dislodged particles or damage produced by arcing could degrade display performance. Dense, thin-film phosphor materials which are well adhered to transparent substrates will provide much smoother surface morphologies, and should be able to withstand significantly higher electric field strength without arcing or screen degradation due to the dislocation of particles.

In recent years, screen soft proofing has matured with the development of color management and display technology, and it has become the direction of printing development and the key of promotion. This article aimed at raising a testing scheme of display performance and adjusting scheme of corresponding display parameters, on this account to test the professional display’s performance, adjust display parameters and make color management. At the same time with reflecting the actual situation of display, a stable and accurate color reproduction environment was provided for screen soft proofing. After that, evaluations were carried out to evaluate printing quality of screen soft proofing on the condition that display’s performance was good, consequently the differences between proofing effects and final printing were studied. The result shows that this testing scheme of display performance can reflect the truth of display which is tested in this paper, the display after adjusted and color management according to this scheme shows good effect in the ability of screen analog proofing original, it can approach the requirements of the printing proofing.

Indium tin oxide (ITO) transparent electrodes are troubled with high cost and poor mechanical stability. In this study, layer-by-layer (LBL)-processed thin films with single-walled carbon nanotubes (SWNTs) exhibited high transparency and electrical conductivity as a candidate for ITO replacement. The repetitive deposition of polycations and stabilized SWNTs with a negative surfactant exhibits sufficiently linear film growth and high optoelectronic performance to be used as transparent electrodes for vertically aligned (VA) liquid crystal display (LCD) cells. The LC molecules were uniformly aligned on the all of the prepared LBL electrodes. VA LCD cells with SWNT LBL electrodes exhibited voltage-transmittance (V-T) characteristics similar to those with the conventional ITO electrodes. Although the response speeds were slower than the LCD cell with the ITO electrode, as the SWNT layers increased, the display performance was closer to the LCD cells with conventional ITO electrode. This work demonstrated the good optoelectronic performance and alignment compatibility with LC molecules of the SWNT LBL assemblies, which are potential alternatives to ITO films as transparent electrodes for LCDs.

Abstrak Penelitian ini berawal dari rendahnya kemampuan Berbicara, pembelajaran menceritakan kembali Fabel yang dibaca/didengar peserta didik kelas VII di SMP N 4 Jambi. Tujuan penelitian ini meningkatkan keterampilan, motivasi dan membantu peserta didik mengatasi kesulitan dalam bercerita fabel, dengan menggunakan media boneka.Penelitian ini dilakukan dengan 2 (dua) siklus dengan masing-masing siklus dirancang 4 (empat) kegiatan, yaitu tahap perencanaan, pelaksanaan, pengamatan, serta refleksi. Data diambil dengan menggunakan instrument lembar pengamatan, data tampilan unjuk kerja atau hasil belajar peserta didik, sikap, dan pengetahuan. Analisis data secara deskriptif dengan teknik persentase. Hasil observasi guru menyatakan aktivitas peserta didik mengalami peningkatan  hasil belajar dari Siklus I , siklus I, dan siklus II, yaitu aspek keterampilan 55,60%, aspek sikap 30,49%, aspek pengetahuan 71,34%. Penggunaan media Boneka meningkatkan keterampilan, motivasi, dan aktivitas belajar peserta didik.   Kata kunci: Media Boneka, Keterampilan Bercerita Fabel Bahasa Indonesia   Abstract This research started from the low ability to speak, The lesson recounts the fable that are read/heard by 7th graders at junior high school 4 Jambi, The purpose of this research is increasing skills, motivation, and helping the learners to overcome difficulties in telling fables by using the puppet medium, This research was conducted with 2 (two) cycles with each cycles was designed 4 (four) activities that is planning, implementation, observation and reflection, Data was taken with using instrument observation sheet, data display performance or learning outcomes of learners, attitude, and knowledge. Analysis of data descriptively with  percentage technique. The result of teacher observation claim the activities of learners have increased learning outcomes from precycle, cycle I, cycle II, that is skill aspect 55,60%, attitude ascpect 30,49%, knowledge aspect 71,34%. The use puppet media enchances motivation skill and learning activity of learners.   Keywords: Puppet media, the skill of telling Indonesian fables

Liquid crystal display (LCD) is one of the most dynamic electronic products in this century. It has been recognized as a key component of media era, since it has many characteristics, such as a low operating voltage, light volume, and excellent performance of full color display, and suitable for LSI drive and the like. In order to break the limitations of LCD, improve its animation display performance as multimedia television monitor, and strongly simplify the manufacturing to ensure the competitiveness on price, we designed a LCD module with the liquid crystal cell of TD-EDA experimental system based on FPGA, and achieved the control of LCD with hardware description language VHDL in this paper. The validation results of compiled program downloaded on programmable logic devices after compiling and simulating show that the LCD we designed can run correctly and relatively perfectly.

Abstract Learned traits, such as foraging strategies and communication signals, can change over time via cultural evolution. Using historical recordings, we investigate the cultural evolution of birdsong over nearly a 50-year period. Specifically, we examine the parts of white-crowned sparrow (Zonotrichia leucophrys nuttalli) songs used for mate attraction and territorial defense. We compared historical (early 1970s) recordings with contemporary (mid-2010s) recordings from populations within and near San Francisco, CA and assessed the vocal performance of these songs. Because birds exposed to anthropogenic noise tend to sing at higher minimum frequencies with narrower frequency bandwidths, potentially reducing one measure of song performance, we hypothesized that other song features, such as syllable complexity, might be exaggerated, as an alternative means to display performance capabilities. We found that vocal performance increased between historical and contemporary songs, with a larger effect size for urban songs, and that syllable complexity, measured as the number of frequency modulations per syllable, was historically low for urban males but increased significantly in urban songs. We interpret these results as evidence for males increasing song complexity and trilled performance over time in urban habitats, despite performance constraints from urban noise, and suggest a new line of inquiry into how environments alter vocal performance over time.
