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.","PeriodicalId":225743,"journal":{"name":"2017 15th International Conference on Quality in Research (QiR) : International Symposium on Electrical and Computer Engineering","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115959418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":225743,"journal":{"name":"2017 15th International Conference on Quality in Research (QiR) : International Symposium on Electrical and Computer Engineering","volume":"201 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123033684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.","PeriodicalId":225743,"journal":{"name":"2017 15th International Conference on Quality in Research (QiR) : International Symposium on Electrical and Computer Engineering","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116536416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":225743,"journal":{"name":"2017 15th International Conference on Quality in Research (QiR) : International Symposium on Electrical and Computer Engineering","volume":"4 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124298018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
