Employees Provident Fund (EPF) has always been a hot topic, from the previous Government permitted “withdrawals” during the pandemic to the present Government disallowing further withdrawals (afraid it would lead to a financial crisis) and allowing emergency loans through an EPF collateral agreement. The latter used median studies to “contribute” MYR 500 to EPF members with less than RM 10,000 in their accounts. Baffled/bewildered by the current Government’s generosity and highlighted in this paper, I used Monte Carlo simulation, a method used by analysts when determining the size of a client’s portfolio to support their desired retirement lifestyle, to establish a reference-type table displaying ideal savings when reaching 50. The Government could use the table mentioned above to give more meaningful contributions to EPF members, apart from EPF active and inactive members, knowing where they stand concerning their current EPF savings.

The performance of industrial waste incineration bottom ash in controlled low-strength material （CLSM） was investigated in this paper, as the quarry dust was added. CLSM mixtures were made from the industrial waste incineration bottom ash, quarry dust, and cement. Tests for fresh density, bleeding, compressive strength, shear strength, hydraulic conductivity, and excavatability were carried out. The com- pressive strength ranges from 60 kPa to 6790 kPa, the friction angle varies from 5°to 19°, and the cohesion is from 4 to 604 kPa. Most of the mixtures are found to be non-excavatable. It is indicated that the quarry dust addition increases the compressive strength and shear parame- ters, decreases bleeding, and increases the removability modulus.

Seamless handover between unicast and multicast multimedia streams

The 12～(th) International Conference on Flow Measurement

作者： Haluk Toral Dasline Sinta Meramat Tajak Petroleum Software Limited Sarawak Shell berhad Sarawak Shell berhad

＜正＞ The paper presents measurements taken with a multiphase flow meter based on neural net methodology at the National Engineering Laboratory and Institute Francais Petrole multiphase test loops and an offshore smart satellite production platform operated by Sarawak Shell berhad Malaysia. The paper also contains a review of the state of the art of multiphase metering technology and an appraisal of potential sources of error inherent in different technologies. The method provides the basis of a multiphase flow meter which can be used under a wide range of operating conditions in oil and gas production lines by tuning against field references.

With the deployment of heterogeneous networks, mobile users are expecting ubiquitous connectivity when using applications. For bandwidth-intensive applications such as Internet Protocol Television(IPTV), multimedia contents are typically transmitted using a multicast delivery method due to its bandwidth efficiency. However, not all networks support multicasting. Multicasting alone could lead to service disruption when the users move from a multicast-capable network to a non-multicast network. In this paper, we propose a handover scheme called application layer seamless switching(ALSS) to provide smooth real-time multimedia delivery across unicast and multicast networks. ALSS adopts a soft handover to achieve seamless playback during the handover period. A real-time streaming testbed is implemented to investigate the overall handover performance, especially the overlapping period where both network interfaces are receiving audio and video packets. Both the quality of service(QoS) and objective-mapped quality of experience(QoE) metrics are measured. Experimental results show that the overlapping period takes a minimum of 56 and 4 ms for multicast-to-unicast(M2U) and unicast-to-multicast(U2M) handover, respectively. The measured peak signal-to-noise ratio(PSNR) confirms that the frame-by-frame quality of the streamed video during the handover is at least 33 dB, which is categorized as good based on ITU-T recommendations. The estimated mean opinion score(MOS) in terms of video playback smoothness is also at a satisfactory level.
