TL;DR: Demonstrates the use of virtual instrument for wireless and internet based automation of energy metering system for functions such as remote meter reading, meter data management, report generation and finally real time and historical trending are realized.
Abstract: Objective: This paper describes the use of virtual instrumentation tool - LabVIEW for web based demand side energy monitoring using GSM based wireless data acquisition. Method: The demand side energy monitoring is carried out by microcontroller based system on Time of Day basis. The demand side energy utilization tracked by the microcontroller based system is transmitted using GSM communication to remote metering infrastructure implemented on LabVIEW platform for real time monitoring. The demand side energy utilization information acquired by metering infrastructure can be accessed over the internet using server - client model based communication. The metering infrastructure is designed to provide SMS based customer service regarding monthly energy utilization. Findings: Demonstrates the use of virtual instrument for wireless and internet based automation of energy metering system for functions such as remote meter reading, meter data management, report generation and finally real time and historical trending are realized. Applications/Improvements: The LabVIEW based virtual instrument application can be improved to perform multipoint wireless communication.

TL;DR: The proposed router outperformed the static router by 22.63% less average latency for E3S benchmark applications and maximum of 55% reduction in buffer requirement and 53% less power consumption is achieved.
Abstract: This paper presents a heterogeneous adaptable router to reduce latency in irregular mesh Network-on-Chip (NoC) architectures. Regular mesh-based NoC architecture may become irregular due to variable sized IPs and needs new routing algorithms to ensure throughput. Therefore, an irregular NoC mesh is considered and an adaptive algorithm is used for routing. The performance measures such as throughput, latency, and bandwidth are defined at design time to guarantee the performance of NoC. However, if the application has to change its communication pattern, parameters set at design time (say buffer size) may result in large area and power consumption or increased latency. Routers with large input buffers improve the efficiency of NoC communication, but they incur excessive power dissipation and hardware overheads. Routers with small buffers reduce power consumption, but result in high latency. In the proposed NoC router, input buffers can be dynamically allocated, thereby, latency can be reduced. In a 4 × 4 irregular mesh NoC with a buffer depth of 4 slots, 20% reduction in latency and 9% increase in throughput are attained using dynamic buffer allocation. An 8 × 8 irregular mesh NoC with the proposed router is exposed to the synthetic traffics like uniform, bit complement, tornado and hotspot traffics and it offered a 30.42% reduction in overall average latency and 18.33% increase in overall saturation throughput. The proposed router outperformed the static router by 22.63% less average latency for E3S benchmark applications. For the same performance, maximum of 55% reduction in buffer requirement and 53% less power consumption is achieved.

24 Nov 2014TL;DR: In this paper, a number of improved designs for Radix-2h online floating-point multiplication are presented, analysed and compared on the basis of latency, throughput, cycle time and resource utilization.
Abstract: Digital signal processing hardware uses digit serial arithmetic when latency can be traded off for higher clock speeds, resource and input-output utilization. Floating-point representations are important when dealing with very large data sets or sets where data range may be unpredictable as these representations may have a larger dynamic range. Field Programmable Gate Array architectures make them suitable as hardware accelerators for implementing high performance floating-point computations. In this paper, a number of improved designs for Radix-2h online floating-point multiplication are presented, analysed and compared on the basis of latency, throughput, cycle time and resource utilization. The architecture of a novel online floating-point multiplier using an interleaved number representation that results in an increased throughput and has the advantage of carrying out normalization for overflow with reduction in cycle time, resource utilization and latency is also presented.

01 Jan 2017TL;DR: In this paper, the effectiveness of the tab with slanted perforation increased with increasing slanted-perforation angle, which caused the disturbance in potential core region of the primary jet and resulting in faster decay of the jet.
Abstract: Jet from convergent nozzle under correctly expanded condition was controlled by two tabs kept opposite to each other with straight perforation and slanted perforation at different angles of 10°, 20° and 30°. This jet was compared with uncontrolled jet and jet with solid tab. It was found that jet with tab of slanted perforation 30° was having a lesser potential core as compared to jet with solid Tab. Further it was found that the effectiveness of the tab with slanted perforation increased with increasing slanted perforation angle. The streamwise vortices introduced by the slanted perforation in tabs were inclined towards the centreline of the jet and thereby causing the disturbance in potential core region of the primary jet and resulting in faster decay of the jet.

TL;DR: This paper made an attempt to bring out a suitable mobility model for vehicular networks, which improves the network performance in accordance with string stability, by incorporating the concept of Fuzzy Cooperative Adaptive Cruise Control mechanism among a platoon of vehicles.
Abstract: Mobility models, which determine the movement pattern of nodes communicating wirelessly, play a vital role in the simulation-based evaluation of Vehicular Ad Hoc Networks. Realistic mobility models enable us to assess the network performance more accurately, and it is required to design a realistic mobility model that mimics the real vehicle scenario. This paper made an attempt to bring out a suitable mobility model for vehicular networks, which improves the network performance in accordance with string stability, by incorporating the concept of Fuzzy Cooperative Adaptive Cruise Control mechanism among a platoon of vehicles. The experimental study and analysis find that fuzziness improves the performance of the network in terms of packet delay ratio, delay and throughput.
