In order to have complete system functionality, smart attendance system is needed to integrate with RFID database handling system. SAS will fetch the appropriate data from RFID database in order to execute the attendance taking process. Furthermore, SAS is also equipped with other rich additional modules to help lecturers and students in the class such as notes distribution and reminder.

A design of the broadband dual-polarized microstrip antennas is proposed by using the simply inset feed technique but slant at desired rotation. In most applications, the requirement of propagation can be met with a single patch structure. However, in some cases, sharp beamwidth was required, as well as maintaining a low profile structure, which arise the development of microstrip patch array antennas. Both design of array antennas in this paper were connected using parallel feed quarter- wave transformer impedance matching technique.

Two different designs of meander line antenna are investigates, without conductor line and with conductor line. The Microwave Office software is used for simulation design process. The antenna is fabricated on a double-sided FR-4 printed circuit board using an etching technique. Then the design has been tested with the advantest network analyzer. The comparison between simulation and measurement results for the return loss and radiation patterns were presented. A bandwidth of 152 MHz and return loss of -37.7 dB were obtained at frequency 2.4 GHz. The gain is comparable to microstrip yagi antenna.

In this effort, implementation of information technologies and systems such as enterprise resource planning (ERP) facilitate the desired level of integration. There are cases of successful and unsuccessful implementations. The principal reason for failure is often associated with poor management of the implementation process. This paper examines key dimensions of implementation of ERP system within a large manufacturing organisation and identifies core issues to confront in successful implementation of enterprise information system. A brief overview of the application of ERP system is also presented and in particular, ERP software package known as SAP R/3, which was the ERP software package selected by Rolls-Royce plc. The paper takes an in-depth look at the issues behind the process of ERP implementation via a case study methodology. It focuses on business and technical as well as cultural issues at the heart of the Rolls-Royce implementation. The case study also looks at the implementation time scales and assesses the benefits from the project both tangible and intangible. r
