In an m-commerce setting, the underlying communication system will have to provide a quality of service (QoS) in the presence of two competing factors—network bandwidth and, as the pressure to add value to the business-to-consumer (B2C) shopping experience by integrating multimedia applications grows, increasing data sizes. In this chapter, developments in the area of QoS-dependent multimedia perceptual quality are reviewed and are integrated with recent work focusing on QoS for e-commerce. Based on previously identified user perceptual tolerance to varying multimedia QoS, we show that enhancing the m-commerce B2C user experience with multimedia, far from being an idealised scenario, is in fact feasible if perceptual considerations are employed.

Psychoacoustic Parameter

Psychoacoustic parameter of sound known as loudness is a major quality factor for assessing the perceptual quality of service of speech signals transmitted through telecommunication networks. The Zwicker and Fastl loudness model is a preferred loudness model and in this work has been programmed to obtain both loudness and loudness level of speeches transmitted over wireless. Here,the best maximum instantaneous loudness of the transmitted speeches is 42.55% of that of the original speech. While the best maximum instantaneous loudness level of the transmitted speeches is 87.06% of that of the original speech. These showed an intuitive and innovative representation of the degradation suffered by the transmitted speeches with respect to the original speech.

Prioritization Scheme

This paper presents a prioritization scheme based on an analysis of the impact on objective video quality when dropping individual slices from coded video streams. It is shown that giving higher-priority classified packets preference in accessing the wireless media results in considerable quality gain (up to 3 dB in tests) over the case when no prioritization is applied. The proposed scheme is demonstrated for an IEEE 802.11e quality-of-service- (QoS-) enabled wireless LAN. Though more complex prioritization systems are possible, the proposed scheme is crafted for mobile interactive or user-to-user video services and is simply implemented within the Main or the Baseline profiles of an H.264 codec.

This study departs from the hajj bailout financing facility which is a booming product because of the customer's interest, but in this case there is a difference in the target achievement between Bank Syariah Mandiri (BSM) Ujungberung KCP which is less successful in improving the hajj bailout products while the Rancaekek KCP is very superior in one consolidation Ahmad Yani Branch Office Bandung. This is what is interesting for researchers to carry out this research, the difference constraints include service quality and promotion factors. This phenomenon raises problems that must be examined, namely how the influence of service quality and promotion of market share expansion products hajj bailouts at Bank Syariah Mandiri KCP Ujungberung and KCP Rancaekek Bandung. This study aims academically to contribute in the study of Islamic economics in worksheets, especially the quality of service and promotion of market share expansion and practically expected to be able to provide input to all employees of BSM KCP Ujungberung regarding the quality of service and promotion of market expansion of bailout products. Hajj that has been successfully carried out by BSM KCP Rancaekek.The conclusion of this study is that there is a significant influence of service quality on the expansion of market share by 53.3% with a strong correlation of 0.730 and through t test, where t counts at 8.245 (> t table), then H_0 is rejected and H_i is accepted. Furthermore, there is a significant influence of promotion on the expansion of market share by 30.3% with a moderate / sufficient correlation of 0.550 through t test, where t counts is 4.219 (> t table), then H_ (0) is rejected and H_i is accepted. Then there is a significant influence of service quality and promotion simultaneously to the expansion of market share by 60.6% and a strong correlation of 0.784 and through Test F, where F count is 67.023 (> F table), then 〖H〗 _ ( 0) rejected and H_i accepted.

Maraknya peredaran obat ilegal membuat resah pemerintah dan masyarakat. Perlu adanya payung hukum untuk memberantas peredaran obat ilegal ini. Selain payung hukum yang kuat diperlukan juga mekanisme pengawasan pengawasan obat yang baik. Penelitian ini memcoba menciptakan suatu sistem pengawasan obat yang menghubungkan setiap stackholder farmasi mulai dari industri farmasi hingga instalasi sediaan farmasi dan terintegrasi pada dua instansi pemerintah yaitu DinKes dan BPOM selaku badan pengawasan melalui infrastruktur Cloud. Sistem yang dibangun menggunakan metode Togaf ADM dengan melibatkan 4 tahapan didalamnya. Untuk menjamin apakah sistem yang dibangun memiliki konsistensi yang baik maka dilakukan pengujian performa server dengan menggunakan parameter Quality of Service. Hasil dari penelitian ini menjabarkan bentuk model database yang bisa digunakan di platform aplikasi yang berbeda serta hasil pengujian performa yang didapatkan nilai dari parameter yang digunakan memenuhi standar tiphon dengan kategori sangat baik, sehingga konsistensi data yang tersimpan akan bernilai positif atau konsistensi data bisa terjamin.
