In this paper, we propose a new contextual bandit problem with two objectives, where one of the objectives dominates the other objective. Unlike single-objective bandit problems in which the learner obtains a random scalar reward for each arm it selects, in the proposed problem, the learner obtains a random reward vector, where each component of the reward vector corresponds to one of the objectives...
This paper addresses Particle Filter (PF)-based hybrid Cooperative Localization (CLoc) strategies consisting of fusing absolute position information from embedded Global Navigation Satellite System (GNSS) with relative distance-dependent estimates using Impulse Radio — Ultra WideBand (IR-UWB) technology. Such hybrid GNSS/IR-UWB CLoc yet cannot benefit from the high precision estimates from the IR-UWB...
Variability associated with input to any PV system is one of the major factors that command the output of the system. In addition to it, technology used, weather conditions, geographical location, local latitude etc. also decide the performance of any solar photovoltaic system. In this paper, the performance of a 40kWp solar photovoltaic plant installed in Faculty of Arts, Dayalbagh Educational institute,...
With the development of intelligent manufacturing technology, it can be foreseen that time series data generated by smart devices will raise to an unprecedented level. For time series with high amount, high dimension and renewal speed characteristics, resulting in difficult data mining and presentation on the original time series data. This paper presented a piecewise linear representation based on...
The order-of-arrival (OOA) estimation of moving items is essential for various emerging applications, for example, baggage sorting and dispatching in airports. In this paper, we show how OOA estimation can be performed by an UWB-UHF RFID system that allows identification and tracking of passive and semi-passive tags attached to objects moving on a conveyor belt. Particle filtering on the energy samples...
Over the last few years, indoor localization has been a very dynamic research area that has drawn great attention. Many methods have been proposed for indoor positioning as well as navigation services. A big number of them were based on Radio frequency (RF) technology and Radio Signal Strength Indicator (RSSI) for their simplicity of use. The main issues of the studies conducted in this field are...
Iceberg query (IBQ) is a special class of aggregation query which compute aggregations upon user provided threshold (T). In data mining area, efficient evaluation of iceberg queries has been attracted by many researchers due to enormous production of data in industries and commercial sectors. In literature, different strategies were found for IBQ evaluation, but using compressed bitmap index technique...
With the development of GNSS, the design and optimum selection of the ranging code is of significant importance for navigation system design. This paper describes the generation of the Weil code based on the design of ranging code. And then in order to select ranging codes of better performance, the paper describes a new optimum selection method in detail. This method is a combination of code selection...
Sleep has always been an indispensable part of human nature, yet it is astonishing that the majority of society has a poor understanding of it and fails to understand the significance of it. In fact, famous scientist Thomas Edison once stated, “Sleep is a criminal waste of time, and a heritage from our cave days.” Yet, as an essential operation in our daily schedule, sleep has a plethora of purposes...
In this paper, a novel microstrip meander-line slow-wave structure (SWS) is proposed for using in V-band traveling-wave tube (TWT). The new omega-shaped microstrip meander-line slow-wave structure has higher interaction impedance by contrasting analysis of the conven-tional U-shaped microstrip meander-line SWS. The transmission characteristics, dispersion characteristic, coupl-ing impedance and beam-wave...
In this paper, we study a positioning method working in DVB-T single frequency networks (SFNs). These networks have several properties useful for positioning (synchronized emitters at fixed and known location, high SNR, OFDM signals containing pilot subcarriers). Thus, their signals may be used as signals-of-opportunity when the user enters a GNSS hostile environment (e.g. dense urban or indoor areas)...
In this work, we present some asymptotic results on the maximum likelihood multi-rank processor for passive wavefront curvature ranging systems using large-scale distributed arrays. We assume that the operation environment for the distributed arrays is subject to a spatial coherence loss. Under an exponential coherence model, analytical expressions for the multi-rank combiners are derived. The results...
The total arterial compliance (TAC) is defined as the sum of systemic arterial compliance which could be calculated at the root of aorta. It is an index to assess the status of arterial stiffness. Pulse wave velocity (PWV) is becoming a clinical index to assess the level of arterial stiffness. This abstract will be discussed the methodology of evaluation of PWV that will be correlating with TAC using...
In many circumstances, it is necessary for a node in a Wireless Sensor Network (WSN) to be aware of its location in the physical world. For example, tracking or event-detection functions are not useful if the WSN cannot provide any information where the event has happened. Some location procedures have been proposed in the IEEE 802.15.4a standard, including the time of arrival (TOA) estimation, the...
Text compression techniques like bzip2 lack the possibility to search or to update substrings at given positions of texts that have been compressed without prior decompression of the compressed text. We have developed Indexed Reversible Transformation (IRT), a modified version of the Burrows-Wheeler-Transformation (BWT) that in combination with run length encoding (RLE) and wavelet trees (WT) allows...
The rapid growth in IEEE 802.11 based wireless LANs has led to new implementations like VoIP applications that require seamless handover. But handoff delays provide a serious barrier for such services to be made available to mobile platforms. Throughout the last few years there has been plenty of research aimed towards reducing the handoff delay incurred in the various levels of wireless communication...
The ability to localize a sensor network is important for its deployment. A theoretical result exists defining necessary and sufficient conditions for network unique localizability (for inter-sensor range-based localization); it has its roots in Graph Rigidity Theory where sensors and links/measurements are modelled as vertices and edges of a graph, respectively. However, critical missions do require...
The evaluation of combination methods for multi-classifier systems is a difficult problem. In many cases multi-classifier combination methods are too complex to be formally studied and the experimental approach is the unique possible strategy. Of course, in order to simulate a multitude of real working conditions, sets of artificial classifiers with diverse characteristics must be generated. This...
