Synchrophasors are the state-of-the-art measuring sensors that sense voltage, current, or frequency with high data rate. This paper presents an approach to analyze the streaming smart-grid data generated by synchrophasors. A novel unit-circle representation is used to visualize the real-time phasor data. A Density based clustering (DBSCAN) method is proposed to cluster the phasor data to detect bad-data for classification, and identifying various fault anomalies. The paper uses datasets from an IEEE 14 bus system test-bed to aid system operators in carrying various predictive analytics and decisions.

Immersion into rich multimedia is now the norm in today's Internet. Combining multiple streams of textual, audio and media data from a variety of sensors and sources, allow the presentation of a world that is almost “real”. Users equipped with portable and wearable devices can become consumers and contributors to an augmented reality. In this paper we describe a general software architecture for an augmented reality immersion network based on crowd sourced media gathering and distribution. We describe a prototypical implementation with cloud and mobile components to establish a secure sharing network, to coordinate and to synchronize the media streams. Joining the content sharing network is subject to peer-to-peer trust management to protect the content and the participants.

One of the key factors in designing a successful multiple classifier system (MCS) is choosing an appropriate combining rule. Many theoretical and experimental efforts have been focused on estimating the probability of classification error for different combining rules. In this work, assuming N classifiers and two independent and identically distributed classes, we investigate using product and modified product rules and derive formulas to estimate their classification error probability under two class distributions, Gaussian and uniform. We also validate our derivations with computer simulations. The performance results of product, modified product, average, and majority vote rules are compared. The comparisons are done in term of probability of classification error as a function of class variance and number of classifiers. The results show that the modified product rule outperforms others while the product rule ranks last.

Development of surface plasmon resonance enhancing surfaces can lead to improvements in fluorescence-based chemical and biological sensing schemes. The motivation of this research is to have a method for easily fabricating plasmonic surface features on silver films which can be controlled by altering the physical properties of sub-layers under the silver film. Here, we report on preliminary work towards fabrication and control of such films through the use of soft lithographic micro-contact printing techniques for the formation of diffraction patterns, and the use of high surface area, low surface energy nanoporous films to drive the formation of nano-scopic gaps within the silver film. Florescence microscopy imaging of fabricated surfaces shows promising results, though further research will be needed to fine tune the surface to produce strong fluorescence emission.

Load balancing optimization is categorized as NP-hard problem, playing an important role in enhancing the cloud utilization. Different methods have been proposed for achieving the system load balancing in cloud environment. VM migration is one of these techniques, proposed to improve the VMs' functionality. Despite of the advantageous of VM migration, there are still some drawbacks which urged researchers to improve VM migration methods. In this paper we propose a new load balancing technique, using Endocrine algorithm which is inspired from regulation behavior of human's hormone system. Our proposed algorithm achieves system load balancing by applying self-organizing method between overloaded VMs. This technique is structured based on communications between VMs. It helps the overloaded VMs to transfer their extra tasks to another under-loaded VM by applying the enhanced feed backing approach using Particle Swarm Optimization (PSO). To evaluate our proposed algorithm, we expanded the cloud simulation tool (Cloudsim) which is developed by University of Melbourne. The simulation result proves that our proposed load balancing approach significantly decreases the timespan compared to traditional load balancing techniques. Moreover it increases the Quality Of Service (QOS) as it minimizes the VMs' downtime.

This paper presents an efficient approach for a vision based localization of multiple mobile robots in an indoor environment by using a low cost vision sensor. The proposed vision sensor system that uses a single camera mounted over the mobile robots field takes advantages of small size, low energy consumption, and high flexibility to play an important role in the field of robotics. The nRF24L01 RF transceiver is connected to the vision system to enable wireless communication with multiple devices through 6 different data pipes. The downward-facing camera provides excellent performance that has the ability to identify a number of objects based on color codes, which form colored landmarks that provide mobile robots with useful image information for localization in the image view, which is then transformed to real world coordinates. Experimental results are given to show that the proposed method can obtain good localization performance in multi-mobile robots setting.

With the growing number of Distributed Generators (DGs) in power systems, demand to utilize Photovoltaic (PV) systems has also shown increase. PV systems are equipped with PV inverters in order to convert DC power to AC power. PV inverters are great sources to improve voltage profile in the utility grid using their reactive power injection feature. On the other hand, the current standards do not allow inverters to inject reactive power, which would be the case in the future and it needs to be investigated. This paper analyzes voltage profiles of IEEE 13 nodes distribution network when PV inverters provide reactive power. Power flow analyses are conducted for various combinations of PV grid interconnections; for fixed PV generation and load profiles and fluctuating PV generation and load profiles. PowerWorld simulations reveal the effect of reactive power injections to the grid as a case study for the distribution network. Results show that reactive power injection improves the voltage profile of the IEEE 13 node system but the size of PV systems should be kept within certain limits to prevent overvoltages in the network.
