In this paper we study a multi-product lot streaming problem in a stochastic job shop with equal and discrete sublots. The problem involves splitting order quantities of different products into different number of equal sublots (NES) and analyzing the effects of sublot-related transportation queue disciplines (TRQD) for different performance measures. Our simulation results show that some combi...
The Lead-Based Multiple Video Transmission (LMVT) problem is motivated by applications in managing the quality of experience (QoE) of video streaming for mobile clients. In an earlier work, the LMVT problem has been shown to be NP-hard for a specific bit-to-lead conversion function φ. In this work, we show the problem to be NP-hard even if the function φ is linear. We then design a fully polyno...
The OSI network layer model provides a strictly separated stacked architecture to abstract the behavior of one layer from the other. Although this model has a lot of advantages, it also makes it easy to lose the bigger picture. In this paper, the authors describe the advantages that can be made by cross-layering the link layer and networking layer to optimize handovers. The performance gain of ...
When using an on-demand media streaming system on top of a network with Multicast support, it is sometimes more efficient to use broadcast to distribute popular content, especially when client demand is high. There has been a lot of research in broadcasting on-demand content to multiple, asynchronous receivers. In this paper, we propose a family of novel, practical techniques for broadcasting o...
This paper presents an effective shuffled frogleaping algorithm (SFLA) for solving a lot-streaming flow shop scheduling problem with equal-size sublots, where a criterion is to minimize maximum completion time (i.e., makespan) under both an idling and no-idling production cases. Unlike the original SFLA, the proposed SFLA represents an individual or frog as a job permutation and utilizes a posi...
To ensure effective shop floor production, it is vital to consider the capital investment. Among most of the operational costs, resource must be one of the critical cost components. Since each operation consumes resources, the determination of resource level is surely a strategic decision. For the first time, the application of Lot Streaming (LS) technique is extended to a Resource-Constrained ...
In this paper, a discrete artificial bee colony (DABC) algorithm is proposed to solve the lotstreaming flow shop scheduling problem with the criterion of total weighted earliness and tardiness penalties under both the idling and no-idling cases. Unlike the original ABC algorithm, the proposed DABC algorithm represents a food source as a discrete job permutation and applies discrete operators to...
Video coding is used under the hood of a lot of multimedia applications such as video conferencing, digital storage media, television broadcasting, and internet streaming. However, offering universal access to video content is far from trivial when taking into account the diversity of current networks and terminals. In this paper, we will discuss how MPEG-21-based technology can be combined wit...
In this paper, we analyze statistical and rate-distortion (R-D) properties of MPEG-4 Fine-Granular Scalability (FGS), which has recently become an important scalable compression framework and a de-facto standard for Internet video streaming. We first propose a novel statistical model of DCT residue that accurately captures the properties of the input to the MPEG-4 FGS enhancement layer. Our res...
Background older people may be less likely to receive interventions than younger people. Age bias in national guidance may influence entire public health and health care systems. We examined how English National Institute for Health & Care Excellence (NICE) guidance and guidelines consider age. Methods we undertook a documentary analysis of NICE public health (n = 33) and clinical (n = 114) g...
