Web usage mining (WUM) is a type of web mining, which exploits data mining techniques to extract valuable information from navigation behavior of World Wide Web users. The data should be preprocessed to improve the efficiency and ease of the mining process. So it is important to define before applying data mining techniques to discover user access patterns from web log. The main task of data preprocessing is to prune noisy and irrelevant data, and to reduce data volume for the pattern discovery phase. This paper mainly focus on data preprocessing stage of the first phase of web usage mining with activities like field extraction and data cleaning algorithms. Field extraction algorithm performs the process of separating fields from the single line of the log file. Data cleaning algorithm eliminates inconsistent or unnecessary items in the analyzed data. © 2011 IEEE.

Overclocking is not a new method for most PC users with the most cost effective perspective for all processors. Two main overclocking methods: Front-Size Bus (FSB) and multiplier changing are used as the popular trends. When the processor need to increase the performance improvement for heavy workloads, overclocking method increases the clock speed cycles by changing multiplier values. In fact, overclocking is the best method to implement with trial and error process which is not warranted by the manufacturers but it is capable. The detail description of types of intensive workloads and multiplier changing overclocking results are shown. The testbed of the paper is based on the specification of Intel Core i7 3770 CPU@3.40 GHz with the core speed 1596.19 MHz as well as bus speed 99.76. The most commonly tools such as CPU-Z, RealTemp, CoreTemp, FFT-z, OCCT tool and Benchmark programs testings are used to validate the system evaluation. © Springer International Publishing Switzerland 2016.

Today, communications technology is one of the most essential roles for our life. People had used many ways of transmissions such as internet, mobile phone and so on. Moreover, VoIP (Voice over Internet Protocol) is also a communications technology. In this paper, we focus on VoIP which transmits voice over packet switched networks such as LANs (Local Area Networks) or WANs (Wide Area Networks). Adding security to a VoIP system, the quality of service and performance of the system are at risk. The contribution of this system has two main parts. Firstly, it illustrates a key from Diffie-Hellman Key Exchange Algorithm. This key is used by AES Algorithm for encryption/decryption process to secure the signaling and voice traffic within a VoIP system. Secondly, it evaluates the performance of a VoIP system to develop speech recognition at receiver. In this system, Mfccs (Mel-Frequency Cepstral Coefficients) is utilized for feature extracting from the incoming voice at receiver. Moreover, Gaussian algorithm is also used for vector quantization in feature matching MFCC features to represent raw speech signal into compact but effective representation that is more stable and discriminative than the original signal. And then the breakdown of call setup is applied by Counting Process in Stochastic Processes. So, this system had captured and analyzed registration, calls setup, voice transmission packets and finally recognized voice or speech by using Mfccs in DSP(Digital Signal Processing) technique. © 2011 Global IT Research Inst.

Not only GSM, WCDMA but also CDMA technology can be used in Myanmar but GSM pre-dominates in the market. There are over million unique subscribers across the country in 2013. Power supply for telecom becomes main challenges in Myanmar where the electricity can not access in rural area. To minimize deficit of power, the government has set a target to covert some of tower sites to renewable solutions by 2015. This paper proposes the use of a PV, wind and diesel generator hybrid system with storage element in order to determine the optimal configuration of renewable energy in Myanmar. This paper discusses the development of a renewable energy sources (RES) that can be used for electric power supply of GSM base station site at any given time and considers the feasibility of developing Solar (photovoltaic)-Wind-Diesel hybrid power systems for supplying electricity to off-grid rural telecommunication. The Hybrid Optimization Model for Electric Renewables (HOMER) was used to simulate and generate feasible solution through combinations of photovoltaic, Wind Turbines and Diesel Generator with a minimum levelised cost of electricity supply and to determine the technical feasibility of the system. © 2015 Institute of Advanced Engineering and Science.

Aloe vera has been used worldwide both for pharmaceutical, food, and cosmetic industries due to the plethora of biological activities of some of its metabolites. The aim of this study was to evaluate the antifungal and antioxidant activities of the leaf extract. The antifungal activity was determined by the agar-well diffusion method against plant and human fungal pathogens. The methanol and ethanol portions of the extracts studied were more bioactive than ethyl acetate portion. It was also observed that the activity was more pronounced on plant pathogen than human pathogen except Candida albicans. This is an indication that the extract has the potential to treat plant fungal infections. The Aloe extract showed the significant antioxidant activity by the DPPH radical scavenging method. Therefore, the Aloe extract provided as natural antioxidant has been used in health foods for medical and preservative purposes.
