Radio Frequency Identification (or RFID) tags has found a wide range of applications in the modern world with a promising future. Tourism directly affects a country's income. In this paper we have proposed a system which uses RFID tags for guidance of tourists. In the proposed system RFID tags are used to guide and to inform the tourists about the given location and surrounding. Tourists usually prefer...
Orthogonal frequency division multiple access is a technique in which single data stream is transmitted with small rate of subcarriers. OFDM system needs FFT processor for generation of subcarriers. A Radix-2 Based 32 bit and 64 Point Pipeline FFT Processor Using bit parallel multiplication process for OFDM system is presented in this paper. Proposed architecture uses single path delay feedback FFT...
The continuous evolution of the telecommunication network architecture has made their network functions to become more available and utilizable. With SDN/NFV network service providers can program their own network functions on the standard commercial hardware platform. SDN/NFV enable more efficient utilization of resources and better service agility. It supports new network services faster and less...
It has been observed that there has been a great interest in computing experiments which has been useful on shared nothing computers and commodity machines. We need multiple systems running in parallel working closely together towards the same goal. Frequently it has been experienced and observed that the distributed execution engine named MapReduce handles the primary input-output workload for such...
This paper proposes a new hardware system to measure the blood glucose concentration. This system has the characteristics of noninvasive, simple and quick. Firstly, we use near-infrared light irradiation fingers. The infrared light transmittance can receive a signal about the blood glucose concentration. Then after an amplifier amplification, this signals will transmit to the Arduino. We use the Arduino...
The continuous dependency on technology has encouraged the integration of BeagleBone Black and C programming language in Universiti Tenaga Nasional in order to produce graduates that are active in the digital shift. The integration is introduced in the "Programming for Engineers" subject for first semester undergraduate students. However, the suitability of the syllabus as well as the integration...
GTS is a new service in GÉANT that allows users to set up wide-area virtual networks via a web-based automatic provisioning system. The virtual networks are built within minutes over the underlying physical infrastructure and thus allow the researcher to carry out network experiments with great flexibility and enable rapid prototyping and innovation. The individual network environments are isolated...
Batch processing is an essential technique to improve packet rates under high-speed network, which has been widely used in high-performance packet IO frameworks. Conventionally, we need to make a tradeoff between high latency at low input loads and high throughput at high loads. In this work, we intend to leverage the smart batching mechanism to dynamically balance the input traffic rate and the available...
In order to realize the function of accurate measurement, multipoint collection and wireless transmission on various environmental monitoring factors in the workshop, a workshop environment monitoring system is proposed based on the technology of internet of things. A number of wireless monitoring nodes are set up in each workshop to collect a variety of environmental information, then transmit the...
Incorporating VHDL programming and implementation using programmable logic devices (PLD) in fundamental digital design course for Electronics Engineering at undergraduate level has become increasingly essential. However it is experienced that integration of VHDL with fundamentals of digital design in one course students give lesser time and importance for VHDL programming. Hence learning objective...
With the fast advance of GPS technology and mobile devices, the location-based queries that can provide useful location information for the user have attracted much attention in the database research community. In this paper, we focus on developing a location-based query system, called the QTWN, which provides various queries to retrieve points of interest (POI) on Taiwan maps. The provided queries...
The emerging field of Immersive Analytics investigates how novel display and interaction technologies can enable people to visualise and analyse data and complex information. In this paper, we present ContextuWall, a system for interactive local and remote collaboration using touch and mobile devices as well as displays of various sizes. The system enables groups of users located on different sites...
Network Functions Virtualization (NFV) is an emerging initiative where standard IT virtualization evolves to consolidate network functions onto high volume servers, switches and storage that can be located anywhere in the network. One of the main challenges to implement NFV is the problem of allocating Virtual Network Functions (VNFs) on top of the physical network infrastructure. Up to now, existing...
In this paper, we make a case for using lightweight containers for fine-grained resource flexing for Virtualized Network Functions (VNFs) to meet the demands of varying workloads. We quantitatively compare the VNF performance and infrastructure resource usage of three instantiations (bare metal, virtual machine, and container) of three selected VNFs. The three VNFs we experiment with are the Mobility...
Virtualization technology is the foundation of Cloud services. To achieve the maximum hardware utilization, Cloud service providers usually host many guest VMs on one VM host. However, as the number of VM increases, the disk accessing performance drops significantly. Disk performance in multiple VM environment is one of the most significant problems in cloud environment. In this work, we propose a...
In the past few years, SAT-based methods in propositional logic have been widely used to tackle practical problems in electronic design automation, software testing and hardware verification. However, lots of industrial problems can naturally be transformed to certain decidable fragments of first-order logic (FOL), which are more expressive than propositional logic. In this paper, we propose a novel...
Parabolic motion cameras are used to obtain better deblurring results of scenes with multiple moving objects. The core of its deblurring process is Iterative Re-weighted Least Squares (IRLS) method. In this paper, we design a hardware accelerator for IRLS flow. The ASIC chip is implemented using TSMC 90 nm technology. It is capable of deblurring a 640 × 480 image captured by a parabolic camera with...
The Arts & Bots Math and Science Partnership program integrates creative technological fluency projects as transdisciplinary activities into non-technical courses, creating a pathway for students of all abilities and areas of interests to engage with engineering and computing. The Professional Development provided by the program prepares teachers from traditional disciplines, such as English,...
FFT is a crucial and necessary design entity lor any current communication applications, especially for OFDM systems. As compared with conventional design approach, which can support only one-radix processing kernel of single-path delay feedback (SDF) FFT, we propose a reconfigurable processing kernel design for multiple-radix types of SDF FFT. In implementation, this kernel hardware engine is reconfigurable...
In this paper, we propose an area-efficient hardware accelerated filter for embedded system. In order to minimize the area of hardware filter, the proposed filter architecture has a single multiplier. The filter operates by reusing the multiplier. In addition, we optimize the quantization bit length by analyzing the relationship between area and preciseness according to the quantization bit length...
