Nanostructured solar cells have multiple approaches by which they can improve photovoltaic performance through new physical approaches in order to reach thermodynamic limits of energy conversion, circumventing material limitations through bandgap engineered systems and providing new routes for low-cost fabrication by self-assembly or design of new materials. In the present talk, we focus on pathways to high efficiency solar cells and energy conversion using various approaches employing nanostructured materials. We first discuss the limits of conventional photovoltaics, and advanced concept approaches to exceed the so-called Shockley-Queisser limit for single bandgap cells. We then discuss particular approaches that are actively being investigated including Si heterojunction solar cells with carrier selective contacts, nanowire solar cells as active components of multi-junction solar cell, quantum dot solar cells for intermediate band devices, and multiexciton generation for increasing the quantum yield above unity in quantum dot and nanowire structures. Hot carrier solar cells are another approach to high efficiency discussed, where the critical issue is reducing the energy loss rate of photoexcited carriers, either in low-dimensional nanostructured materials where this rate is reduced, or in phononic bandgap materials in which nonequilibrium phonons reduce carrier cooling, and allow extraction at high energy. Another way that nanomaterials improve efficiency which we discuss, is in improving light trapping of incident solar radiation, using nanowires and nanoparticles as scatterers in the diffraction limit, to increase absorption by increasing the optical path length in the device. Finally, we discuss hybrid high temperature multijunction photovoltaics coupled with concentrating solar thermal in order to improve the system efficiency above either that of the photovoltaic or CSP system by itself.

In this paper, an Environmental Decision Making Tool with Renewable Energy (EDMTRE) is proposed with the resources cost as constraints. Modifed ReCiPe Version 1.3 Model is adopted to represent the midpoint indicators. A three-method hybrid; Modified Firefly Algorithm with Levy Flights and Derived Mutation (MFA-LF-DM) with parameters brightness, distance, attractiveness, movement, randomness reduction and mutation is used to validate the EDMTRE on IEEE 30-unit system. The levy flights reduce the random movement of the objective function while the derived mutations are improve the exploration of the candidate solution. The uncertainties and variability of the renewable sources are modelled using Structural Path Analysis (SPA). The results are analyzed under optimal emissions, health and ecosystems end points. From the simulated mid-point indicators, it is apparent that the deployment of RE results in more accurate environmental emissions when the resource cost is constrained. Further, the effects of PV technology to the environment are four times more adverse compared to wind.

The impact of cloud computing and sharing physical resources simultaneously between several virtual instances can be crucial for the designing real-time and time-critical applications. This especially applicable to cases when the target is to deliver reliable network services. In this paper, we primarily aim at investigating the timing behavior in the cloud environments where the resources are shared among up to 50 instances. Moreover, we extend the previously performed experiment with the simulation of various background tasks where the key use-case is the deployment of secure and reliable network applications in virtualized environments. The measurements have been performed on host-based model QEMU/KVM and include different method for time acquisitions and waiting operations. Providing detailed statistical data, we have been analyzed the performance of timing part for the general network application and found some interesting phenomena about the behavior of Linux standard sleep calls. Considering these results, corresponding recommendations about using timing mechanisms have been offered.

This paper presents a framework for real-time contingency screening using a situational awareness oriented tool. While some contingencies might have a significant impact on power-system stability, the impact of others is negligible. The consequences of a contingency depend on network conditions. Therefore, fast and effective tools for rapid recognition of hazardous operating conditions from the stability point of view are required. For that purpose, a fast method is proposed, which carries out on-line stability assessment with respect to first swing transient stability. The proposed method is segmented into two steps. In the first step, a database is constructed, which consists of a large spectrum of pre-fault operating points, as well as the critical clearing times of several contingencies. In the second step, a pattern recognition method called Principal Components Analysis is applied, in order to develop a metric, which evaluates the similarity of operating conditions with respect to the first-swing stability problem. The IEEE New England system is used to test the proposed method regarding the assessment accuracy and computation time. However, practical implementation of this concept would be closely linked to the development of WAMPAC systems.

Simple information lookup tasks (e.g. “What the weather like in London?” or “What is the population of the UK?”), are currently well supported with traditional search engines, and more recently with intelligent personal assistants. Intensive knowledge tasks, (e.g. “How do countries with low GDP per capita rank in emigration?”), however, require combining and cross referencing data from multiple sources to get to an answer have typically not been well supported. Our ability to support these types of information tasks on the Web is currently compromised by the inherent document/application nature of the Web itself. End-user mashup tools traditionally approach this problem by assisting users in structuring unstructured content form web pages and then support information-oriented tasks over the structured content. Motivated by the fact that more and more structured data is available on Web pages we investigate another possible solution: how to extend traditional Web navigation, which the majority of end users find intuitive, to include more data-centric behaviour. With mashpoint we propose a simple architecture, which would support an interaction that allows web pages to be linked based on similarities of the entities in their data. Linked in this way, queries that traditionally require the tedious work of joining information form several pages can be performed with simple web-like navigation. The paper focuses on evaluating if the proposed interaction is one that users would be able to understand to execute intensive knowledge tasks. We ran two separate studies: first to explore if the interaction concepts introduced are easily learnable and to gather initial feedback on our prototype, and second to explore design options which can inform how to address discovery challenges when large amount of pages are linked in this way, therefore assessing the feasibility of this model to work on a Web-scale.

Nowadays, finding the Unmanned Aerial Vehicle (UAV) position in the absence of GPS is attractive and challenging problem in the research community. In this paper, we present a novel algorithm for mini UAV indoor localization based on distance measurements between the UAV and the existing infrastructure consisting of WiFi Access Points. Our algorithm uses two well-known techniques from the literature: Multi-dimensional Scaling (MDS) and Weighted Centroid Localization (WCL). Through extensive simulations we have shown that our algorithm is very suitable for indoor localization of mini UAVs. For small radio-range error, our algorithm exhibits a small localization error of less than 5% of the radio range.

The paper presents a QoS framework for terminals with multi-RAT (multiple radio access technologies) interfaces for heterogeneous network environment. It investigates a QoS provisioning with vertical multi-homing and multistreaming features for 5G heterogeneous networks. The presented enhanced framework for 5G systems leads to better performance opportunities for multimedia services with very high level of QoS provisioning in different radio access network (RAN) conditions. The system framework is user-centric oriented, with ability to simultaneously handle multiple RAN connections, choosing the most appropriate RAN for each used service. This paper evaluates the key QoS parameters for multimedia traffic in heterogeneous mobile and wireless scenarios were multiple RANs coexist in the simulation set up. The simulation scenarios includes 3G, 4G, and 5G radio access networks and use Genetic Algorithm and Linear Programming algorithm to solve the optimization problem. The analysis shows significantly high QoS performance for the achievable aggregated throughput and multimedia access probability ratio in heterogeneous wireless and mobile environment, especially in case of large number of available heterogeneous nodes.

In this project, we developed a chess play system based on Kinect vision sensor, which recognizes different hand gestures as a command and sends these commands to V-REP robotic simulation tool. Delta type robot will play chess according to the commands sent via vision software. In our system, we have tested for 2 different chess opening scenarios and DOF checking mode scenario, then we obtained results. Hence we propose an integration between Kinect hand gestures and V-REP simulation.
