  • Implicit Bit Allocation for Combined Coarse Granular Scalability and Spatial Scalability

    A new type of implicit bit allocation (IBA) is studied for the combined coarse granular scalability (CGS) and spatial scalability. Given a region which is a quality level at a spatial resolution and an input of weighting factor in the region that is determined by customers' interest, the IBA is formulated as a multiple objective optimization problem. The IBA exhibits a distinguished feature that allows bits allocation to each region being fixed and only tradeoff between motion information and residual information in each region can be properly set such that coding efficiency of each region is guaranteed in order according to the weighting factor. Due to the nonlinearity of the combined CGS and spatial scalability, this optimization problem is very complex. In this paper, a simple solution to the optimization problem is proposed by using the conventional approach of "Divide and Conquer" or "Hierarchy." Two cross-layer motion estimation/motion compensation (ME/MC) schemes that were introduced for the CGS and spatial scalability are further adopted to support the solution. It is shown that a combined CGS and spatial scalability scheme together with adaptability to customer composition allows the solution to achieve a customer oriented scalable tradeoff (COST)

  • Bounding Communication Energy Overhead in Parallel Networks with Power-Delay Scalability

    We propose the energy scalability and power-delay product scalability as new metrics for calculating and estimating boundaries on the energy overhead of parallel processing systems. Because both properties consider network topology and the algorithm to be implemented, they are shown to be effective in predicting the energy scalability of a multiprocessor in the most general case. Power-delay scalability is then shown to provide upper bound and lower bound estimates when analyzing the energy scalability of a multiprocessor while significantly reducing the computational cost of directly calculating the energy scalability. Energy scalability is an effective metric for predicting the energy overhead cost when using a parallel processor versus a single processor. Power-delay scalability is a means for estimating energy scalability on a system when exact calculation may be difficult due to variation in power levels which have become common with dynamic voltage frequency scaling.

  • Fine spatial scalability in wavelet based image coding

    Wavelet transform based image coding algorithms have the two inherent scalable features of SNR scalability and spatial (or resolution) scalability. However, fine scalability is supported only for the SNR, but spatial scalability is usually restricted to scales of powers of two which may not be considered fine. In this paper, we introduce the fine spatial scalability to wavelet transform based coding systems, by examining the relationship between the subbands of wavelet packet and the original signal spectrum. The proposed fine spatial scalability is useful for effective image resizing and efficient image data transmission according to the display resolution.

The paper studies the results obtained in measuring the response time of the server and the processing time of the server when dealing with a large number of requests by modifying the configuration of the machine, increasing the number of cores the machine has and increasing the RAM capacity. This represents a test to see how many requests a server can process and complete when dealing with large amount of data in a short period of time.

  • Scalability Analysis of the OpenAM Access Control System with the Universal Scalability Law

    The scalability of a software system is greatly impacted by the scalability of the underlying access control system, which makes analyzing the scalability of that access control system paramount. However, this is not trivial, as contemporary access control systems have a myriad of architectural deployment variations, each of which has a potentially large impact on overall system throughput. There is a need for a systematic approach to map these architectural variations to a reference model which allows to make comparisons and to identify trade-offs. This work provides a piece of the puzzle by demonstrating how this can be achieved by systematically applying the Universal Scalability Law (USL). We illustrate our approach by performing a rigorous scalability analysis of the OpenAM access control system for various deployment alternatives in the domain of authentication. We conclude that the approach is able to provide both qualitative and quantitative results which can be translated into practical operational recommendations for the envisioned types of system deployments.

  • Optimal scalability of fiwi networks based on multistage stochastic programming and policies

    The large demand of bandwidth due to new and future applications from services being implemented such as smart grid (SG), smart cities (SC), and the Internet of Things has triggered a focus of interest from the scientific community on issues related to the planning and scalability of the communications infrastructure. In this paper, we present three new and important contributions regarding the deployment of FiWi networks that support users who benefit from the services provided by SG and SC. We first propose a planning model, and then formulate a mixed linear programming optimization model using multistage stochastic programming, and finally propose an algorithm, called MOA-FiWi, which has the capacity to handle medium and large instances of the problem and give feasible solutions for the optimization process, where scalability indices between 85%-95% are reached with respect to the projected stochastic values. The proposed model considers the scalability and capital and operating expense, as well as the uncertainty management in the different stages of time-space through multistage stochastic programming. The proposed model presents flexibility in decision making as the time stages progress. This allows for the planning of green fields, as well as the updating of networks that already have communication infrastructure.

  • Mixed spatial and SNR scalability for TVM geometry coding

    Time Varying Meshes (TVMs) are sequences of three-dimensional models created from multi-camera images. Like other kinds of mesh sequences, it has a great need for compression, in order to become largely usable. Alongside with other types of signals, mesh coding has received considerable attention towards scalable coding, which is a very important feature in many kinds of coded signals. Scalable mesh coding can be divided basically into three types of scalability: temporal, spatial and SNR (signal-to-noise ratio). In this work we focus on the use of block-based and run-length encoding aiming at achieving a combination of spatial and SNR scalability for the geometrical information of TVM. Our results have shown that it is possible to achieve scalability with only a minor increase in rate over a previous coding method.

  • Medium grain scalability for SHVC

    In the scalable extension to HEVC (SHVC) a high level syntax approach to scalability is standardized which enables temporal, spatial and quality scalability. While the chosen layered approach shows a reasonable performance, it only allows for the decoding of entire layers. This coarse grain scalability might not be suitable for applications where a precise adaption to varying channel conditions is required. A high layer modification to the decoder prediction structure is applied, which enables high quality decoding of intermediate layers in case not all pictures from the enhancement layer are decodable. Measurements show that an average BD-PSNR gain of 0.54 dB to 0.61 dB compared to conventional SHVC can be achieved. It is further shown how medium grain scalability can be realized with the scheme of key pictures, as presented in earlier work. It was shown how some high layer modifications to the prediction structure similar to the scalable extension of H.264/AVC can significantly reduce the complexity on the decoder side. Measurements reveal that the average BD-PSNR gain compared to conventional SHVC can be further increased to between 0.63 dB and 0.73 dB.
