1. A CMOS ENVELOPE TRACKING POWER AMPLIFIER WITH HYBRID BIAS MODULATOR

Authors: HEARYUN JUNG , JUNGHYUN HAM , YOUNGOO YANG

Abstract: This paper presents an envelope tracking power amplifier (ET PA) using a hybrid bias modulator for mobile terminal applications. The hybrid bias modulator consists of a linear amplifier and a switching amplifier. The CMOS PA has a two-stage single-ended structure. For 1.75-GHz long-term evolution signal with 5-MHz bandwidth, 7.3-dB peak-to-average power ratio (PAPR), and 16-quadrature amplitude modulation, the CMOS ET PA delivers a power-added efficiency (PAE) of 30.5 %at an average output power of 21dBm. The ET PA also delivers a PAE of 24.2 % at average output power of 17 dBmwhich is 6.9 % higher than that of the stand-alone PA.

Abstract: Institutions all over the world are continuously exploring ways to use ICT in improving teaching and learning effectiveness. In higher education, the teaching methodologies are changing from the classroom-based methodology to the so-called Virtual Learning Environment (VLE). To meet the social demands for internationalized higher education, we propose a new automated authoring system for recording and capturing an on-line presentation in the WebELS system. The proposed system enable generating eLearning contents automatically based on a real-time presentation by synchronizing the presenter video and slide-documents materials, which is very valuable for students who did not grasp specific topics, to repeat important parts of the presentation. Furthermore, for those who were not able to attend the live presentation, they can access to the learning contents created at the server side for later reviewing. The automated system is proposed to work on the cloud-computing environment to ensure

3. REQUIREMENTS ENGINEERING MODEL FOR THE INTEGRATION OF PERFORMANCE MANAGEMENT SYSTEM WITH BUSINESS INTELLIGENCE AND ANALYTIC

Authors: AZIZ DERAMAN , JAMAIAH H. YAHAYA , NUR HANI ZULKIFLI ABAI

Abstract: The importance of applying Business Intelligence and Analytic (BIA) to support Performance Management System has been a recent interest in research with many organizations increasing their investment in BIA to enhance their technological ability and support in decision making. However the implementation of this technological enhancement requires precise planning to ensure return of investment. Theoretical research is conducted to identify a suitable framework for the requirements engineering phase for PMS and BIA integration. The framework combines three main requirements engineering approaches for Business Intelligence and merges performance management and analytic perspectives.
