In this paper, a simple but efficient permutation enhanced parallel reconstruction architecture for compressive sampling (CS) is proposed. In this architecture, a measurement matrix is constructed from a block-diagonal sensing matrix, the sparsifying basis of the target signal, and a pre-defined permutation matrix. In this way, the projection of the signal onto the sparsifying basis can be divided...
The Discrete Cosine Transform (DCT) is the most widely used transform for image compression. The DCT approximation or the Binary Discrete Transform (BinDCT) [1] has shown to be a promising alternative to the DCT for its implementation simplicity, close performance and compatibility to the DCT. In this paper, we aim to present efficient VLSI architectures with a low BinDCT complexity implementation...
Cloud computing has experienced enormous popularity and adoption in many areas, such as research, medical, web, and e-commerce. Providers, like Amazon, Google, Microsoft, and Yahoo have deployed their cloud services for use. Cloud computing pay-as-you-go model, on demand scaling, and low maintenance cost has attracted many users. The widespread adoption of cloud paradigm upshots various challenges...
In complex systems, like the modern air traffic system, human operator taskload can have a profound influence on how well the system performs. Because of the system's complexity, however, it can be difficult to determine all of the situations where taskload issues can arise. Simulation and formal verification have been used separately to explore human taskload in complex systems. However, both have...
The web-based Go-Smart environment is a scalable system that allows the prediction of minimally invasive cancer treatment. Interventional radiologists create a patient-specific 3D model by semi-automatic segmentation and registration of pre-interventional CT (Computed Tomography) and/or MRI (Magnetic Resonance Imaging) images in a 2D/3D browser environment. This model is used to compare patient-specific...
The application and research interest over utility-scale battery energy storage systems have grown significantly over the last years. To achieve utility-scale, series and/or parallel connection of many battery packs with power rating of a few hundreds kilowatts each is the most viable technology at present. The major challenge regarding the connection of battery packs is charging imbalance. This paper...
Undisciplined cohesion and coupling undermine countless aspects of quality software. Students, however, unfortunately tend to gravitate toward such approaches. This system mitigates this problem by forcing them to communicate with their components through a well-constrained hierarchical virtual network of networks. The application is a dynamic, plug-and-play aircraft fly-by-wire system that processes...
Dynamic nature of distributed architecture is a major challenge to avail the benefits of distributed computing. An effective solution to deal with this dynamic nature is to implement a self-adaptive mechanism to sustain the distributed architecture. Self-adaptive systems can autonomously modify their behavior at run-time in response to changes in their environment. This capability may be included...
Multicore embedded systems have evolved to appear in different domains. In this paper, we explore and compare various on-chip architectures with respect to a number design metrics. Unlike earlier published works that majorly concern with optimizations in processor, memory and cache hierarchies, in this paper, we aim to ascertain the best on-chip architectures for given processor cores, Level 1-2-3...
As the network is being evolved towards the content-centric network and the content itself is more focused rather than the host, a new paradigm called content-centric networking (CCN) is being considered for the Future Internet. Because the traffic in the Internet and wireless network has been increasing rapidly due to the continued proliferation of mobile devices, it is important to minimize the...
For all Locator Identity Split protocols to work, a mapping infrastructure is required to maintain the binding between the Locators and Identifiers. However, the mapping infrastructure naturally becomes one of the main scalability concerns when there are a large number of mobile nodes to support. This paper implements and evaluates a tiered architecture in which the mapping infrastructure is divided...
Finding a perfect Embedded Engineer in India is really a challenge for private organizations. Lack of practical experience and real time exposure let the companies to think about a Fresher. As of advancement in the technology the academic regulations should also be updated. Embedded System is a fast and vast emerging field where a lot of employability is required in recent days. In order to update...

It is design to generate stable control signals even when noise level reaches several tens of millivolts. The trickle current is as low as 200mA enabling longer life cycle for Li-Ion battery. The large current reaches 1A without any impact on trickle current offering a faster charging time for Li-Ion...
With the help of simulation tools, users can evaluate new proposals in cluster environment efficiently.

Task-aware network scheduling and network-perceived task placement algorithms can...
Simulation is a tool offering several advantages in the field of automated manufacturing systems, permitting their analysis and evaluation overcoming complexity, cost, scaling, risk, and timing issues. Gamification technologies may complement limitations of conventional engineering systems towards a more natural human way of working. A gaming platform is utilized for the purpose of building an industrial...

Moreover, we address our problem with the survivability assumptions and propose several scenarios that can be applied to provide the required protection. We perform numerical experiments to compare proposed survivability scenarios and investigate the problem of providing survivability to both static and dynamic...
The main challenge for a design engineer is not only to design a successful SoC with a well-structured and synthesizable RTL code but also to design it with efficient in energy and optimized in power consumption. The aim of the paper is to implement AMBA APB (advanced microcontroller bus architecture — advanced peripheral bus) Bridge with efficient deployment of system resources. For this, simulation...
This paper investigates the distributed Q-learning approach to secondary LTE spectrum sharing, its autonomously emerging spectrum usage patterns, and their impact on the primary and secondary user quality of service (QoS). Large scale simulations of a stadium temporary event scenario show that it is capable of servicing a dramatic 51-fold increase in offered traffic, but with no need for additional...
In order to observe and understand the architectural behavior of applications and evaluate new techniques, computer architects often use simulation tools. Several cycle-accurate simulators have been proposed to simulate the operation of the processor on the micro-architectural level. However, an important step before adopting a simulator is its validation, in order to determine how accurate the simulator...
Traffic engineering is a key in effective utilisation of the road network infrastructure. Simulation assists traffic engineers making informed decisions on how to operate and direct traffic within the road networks. These simulations are complex, generate big data and require high-powered computers, which can process information faster than real time, to ensure the results can be used to affect traffic...
