Organic light emitting diodes (OLED) are considered to be a promising candidate for light sources as well as for flat panel display because of their numerous advantageous. Two important parameters of an OLED among many other parameters to measure OLED performance are operating voltage and luminance. Those two parameters are believed to be strongly influenced by an anode and cathode workfunction of materials used as electrodes. In this paper, we study the effect of anode and cathode workfunction on the operating voltage and luminance of a single emissive layer organic light emitting diode. Devices with five different cathodes: Aluminum (Al), Calcium (Ca), Magnesium (Mg), Argentum (Ar), and Cuprum (Cu) and three different anodes: Indium Thin Oxide (ITO), Poly-(3,4-Ethylenedioxidythiophene)-Poly (Styrene Sulfonate) (PEDOT:PSS), Zinc Oxide (ZnO) are compared and analyzed. A 2 nm thick of Polyfluorene (PFO) is used as an emissive layer. SimOLED is used to simulate and analyze both electrical and optical characteristics. Current voltage luminance (IVL) characteristics are simulated under forward biased from 0 to 10 V. We found that the use of anode with higher workfunction can reduce operating voltage as well as increases device luminance. On the other hand, the use of lower workfunction of cathode can reduce operating voltage however it is not always increasing device luminance. The decrease of the operating voltage by increasing anode workfunction and decreasing cathode workfunction are ascribed to the barrier lowering of the holes and the electrons respectively.

This paper presents the comparison of power captured by vertical and horizontal axis wind turbine (VAWT and HAWT). According to Betz, the limit of maximum coefficient power (CP) is 0.59. In this case CP is important parameter that determines the power extracted by a wind turbine we made. This paper investigates the impact of wind speed variation of wind turbine to extract the power. For VAWT we used H-darrieus type whose swept area is 3.14 m2 and so is HAWT. The wind turbines have 3 blades for each type. The air foil of both wind turbines are NACA 4412. We tested the model of wind turbine with various wind velocity which affects the performance. We have found that CP of HAWT is 0.54 with captured maximum power is 1363.6 Watt while the CP of VAWT is 0.34 with captured maximum power is 505.69 Watt. The power extracted of both wind turbines seems that HAWT power is much better than VAWT power.

Latent Dirichlet Allocation has been developed as topic-based method which uses reasoning to determine the topics of a document. There are many methods of reasoning used for Latent Dirichlet Allocation, including the Gibbs Sampling and Mean Variational Inference, the most widely used in research. However, there have not been many studies that discuss the implementation of these methods on the Indonesian text, so analysis is needed to compare its performance in generating feature extraction. Therefore, in this paper, will be implemented the method of reasoning Gibbs Sampling and Mean Variational Inference for Latent Dirichlet Allocation on Indonesian text. The objective is determining the performance of both algorithms on Indonesian text so it can provide a reference about the better reasoning method for Latent Dirichlet Allocation on Indonesian text. The research was implemented on digital Indonesia news text data with 100 documents. The tests are conducted on feature data as the result of extraction process using three type of evaluation metric. The test results show that Gibbs Sampling has a better performance than Mean Variational Inference for Latent Dirichlet Allocation on Indonesian text.

A shear horizontal surface acoustic wave (SH-SAW) device is used as a sensor for the liquid environment. As a main particle displacement of the SH-SAW is parallel in the propagation surface and perpendicular in the propagation direction, the SH-SAW does not radiate its energy into the liquid. Therefore, SH-SAW is suitable for the liquid measurement. In this paper, particles in oil are measured by using the SH-SAW. The experimental results show that the velocity and attenuation changes increase with increasing the amount of the iron particles. Whereas the velocity change obtained is qualitatively explained by the perturbation theory for the mass loading, the attenuation change cannot be explained. Therefore, it is necessary to develop the new theory for particle loading in oil environment.

Palm vein recognition is developing biometric identification technology. It can be used in physical security and information security for selective control of access to a place or resource. A palm vein recognition has been gaining research interest from last few years because it use physiological intrinsic that uniqueness, stability, not easily spoofed and damaged and have live body identification. There are consists of the following steps: Image acquisition from the database and Pre-Processing, Finding of Region of interest, Extraction of Palm Vein pattern Features and Matching. Prior to the palm vein recognition, vein extraction is generally required for a better recognition. In this paper we propose a vein extraction method modified of the Local Binary Pattern (LBP) combining with Probabilistic Neural Network (PNN) for matching. The aim of the proposed system is to improve the accuracy of palm vein recognition. Simulation result show that the proposed method has a higher recognition rate for palm vein recognition comparing to the other basic Local Binary Pattern.

Energy security is one of the important factors for energy policy of the country. However, there are many concepts offered by the researchers on energy security, leading to such a diverse and complicated interpretation. Here we develop a novel concept which elaborates the global perspectives. It is realized through a deep evaluation on energy security evolution, followed by a philosophical study of the subject matter and sight of view of energy security, resulting in an integrated energy security theory. The concept is applied to quantify energy security of Indonesia. The operational concept is a set of measurement instruments consisting of 7 dimensions, 31 indicators and 97 sub-components using dynamic programming algorithm. The result of this study provides an approximated number reflecting the aggregate index of energy security.

The question of energy management is a major engineering challenge in any wireless communication system that is constrained by finite battery resources. In this article we address the problem of transmit power control in a multi-user wireless network with a single base station and random time-varying channels transmitting in parallel and interfering between each other. We suggest a stochastic particle system for studying the game of control; specifically, the channels are modelled as purely discontinuous Markov processes with known characteristics. The signal to interference plus noise ratio (SINR) determines the interactions among particles. Dimensionality reduction of the multi-objective optimization problem relies on chaos propagation, i.e., on the fact that the independence of particles persists in time as and when their number becomes large. And then we solve the optimal control problem for one representative of the particle system. Here we develop a martingale approach for an alternative open-loop optimal control instead of the feedback one since the latter is not computationally feasible.

Battery energy capacity in an application system is determined by the amount of electrical energy spent to the load and time consumption. The system reliability depends on the supply of electrical energy from the battery as the power source. The energy capacity of the battery will ensure the services provided by the unit device or equipment. As an example, the UPS system provides clean, conditioned, and continues power supply for sensitive loads such as airlines computers, data centers, communication systems, and medical support systems in hospitals, etc. Therefore, it is important to estimate the accuracy of the remaining battery capacity at any time. Generally, the UPS system provides a regulated sinusoidal output voltage with switching operation and will give power to the main applications. Some UPS inverters work by utilizing power from the battery modules. The switching operation that operated by the device, will generate high frequency ripple. Many other battery applications can be analogized as a fixed load. This means that the load does not change until the energy capacity of the battery is reduced. Both static and dynamic loads will affect the battery's internal resistance. Some literatures describe the important factor of the battery modules system performance and the degradation rate associated with battery internal resistance. This paper explores how the decreasing battery capacity using the DC current load correspond to the increasing battery internal resistance. We do some experiments on discharging battery with switching load current at 10 second measuring time. We investigate and analyze the difference effect of the battery capacity on the internal resistance battery. We conclude that on continues battery loading will decrease the battery capacity which corresponds to the increasing the internal resistance value.

Fiber Optic Gyroscope is an optical sensor that can determine the position of the angle of motion of an object. FOG works based on the Sagnac effect, which states that the phase shift between two opposite waves propagates in the interferometry of the rotating ring, and proportional to the angular velocity. Goodness performance indicator of measurement system, is having a small noise. Angle Random Walk is the biggest noise contribution to the error value. In this research, noise estimation from ARW has been done. OFOG performance based on ARW has been described in the ARW simulation based on photon emission and the amount of data sampling per time. The effect of ARW on performance is explained on the PDF graph. Error reduction techniques from ARW values have also been presented to improve OFOG performance. FOG measurement system was developed and experimental results were discussed in this research.
