The Belle II experiment [1], the successor of the Belle experiment [2], will go into operation at the upgraded KEKB collider (“SuperKEKB”) in 2016 [3], [4]. SuperKEKB is designed to deliver an instantaneous luminosity ℒ = 8×1035 cm−2 s−1, a factor of 40 larger than the previous KEKB world record. The Belle II experiment will therefore have to cope with a much larger machine background than its predecessor...
In this paper, oppositional based gravitational search algorithm (OGSA) is presented to tune the parameters of power system stabilizer which are added to the excitation to damp low frequency oscillation that pertain in large power system. The most important issue for applying oppositional based GSA is to reach the optimal value in less time. This scheme enables the process to reach the desired value...
Progress in invasive brain research relies on signal acquisition at high temporal- and spatial resolutions, resulting in a data deluge at the (wireless) interface to the external world. Hence, data compression at the implant site is necessary in order to comply with the neurophysiological restrictions, especially when it comes to recording and transmission of neural raw data. This work investigates...
A Time Projection Chamber (TPC) with its 3-dimensional tracking and particle identification capabilities is a very powerful detector for high multiplicity events. TPCs are used for tracking in several experiments such as ALICE, STAR and many others. A drawback of such devices is the restriction to trigger rates of the order of 1 kHz due to the necessity of a gating grid which prevents ions produced...
This paper presents a fuzzy partition and Tsallis entropy based thresholding approach for multi-level image segmentation. Image segmentation is considered as one of the most critical tasks in image processing and pattern recognition area. However, discriminating many objects present in an image automatically is the most challenging one. As a result, multilevel thresholding based methods gain importance...
This paper presents a wireless system, designed for electrocortical (ECoG) neural recordings, consisting of an implantable flex-rigid ECoG array and a wireless electronic platform. The array is designed for implantation on top of the visual cortex of a Rhesus monkey. The electronic platform contains pre-amplifiers and multiplexer stages, analog-digital converters (ADCs), an inhouse developed and reconfigurable...
Low dose X-ray Computed Tomography (CT) is clinically desired to reduce the risk of cancer caused by X-ray radiation. Compressed Sensing (CS), which allows images to be formed from incomplete data, enables large dose reduction to be achieved. Though this remains to be clinically unrealized due to excessive computation times. In this paper we demonstrate a fast, complete CS-based ℓ2-TV minimizing CT...
Solar Photovoltaic Cell is the basic part of the process of extracting solar energy from the Solar Radiation. Using it for a long time can cause its deterioration which reduces the performance of the solar cell. This deterioration depends on many factors of which environmental condition is one of them. This paper mainly focuses on the studies on deterioration of a Monocrystal Solar Silicon Photovoltaic...
Axial brain slices containing similar anatomical structures are retrieved using features derived from the histogram of Local binary pattern (LBP). A rotation invariant description of texture in terms of texture patterns and their strength is obtained with the incorporation of local variance to the LBP, called Modified LBP (MOD-LBP). In this paper, we compare Histogram based Features of LBP (HF/LBP),...
Applications of low cost wireless sensor networks (WSN) in precision agriculture is gaining popularity because of the ability of sensors to provide site-specific data over a variable field. Wireless communication between nodes is impeded by the surrounding vegetation of the plants being monitored. To guarantee reliable communication between sensor nodes, the initial node density and topology of a...
When a magnetic rotor is simultaneously rotated and translationally moved above an aluminum guideway a traveling time-varying magnetic field is created in the air-gap. This field induces eddy currents in the guideway that can simultaneously create suspension and propulsion or braking forces. The transient fields and the forces created by this moving rotor are modeled using a novel 2D analytic based...
This paper proposes a platform that allows the users to transparently interconnect instances of the software audio signal processing engine without the need of a custom implemented data transport hardware. The platform is focused on distributing the signal processing across different computers in order to increase the overall quality of the signal processing and/or to ensure a more convenient sound...
The increasing density and data rate of unlicensed band wireless devices in small office and home (SOHO) environments has led to significant inter- and intra-radio interference problems. Multiple competing standards such as the IEEE 802.11b/g, Bluetooth and ZigBee, all of which operate in the 2.4 GHz ISM band, can interfere with each other when used in typical indoor environments, potentially causing...
Selection of reliable genes from micro array gene expression data is essential to carry out a diagnostic test and successful treatment. In this regard, a rough set based gene selection algorithm is developed recently to select genes from micro array data. In this paper, a fuzzy discretization method is proposed for rough set based gene selection algorithm to compute relevance and significance of continuous...
The impact of power efficient wireless sensor networks (WSN) is getting more and more important, as it is built of battery driven sensor nodes (SN). Beside common low power techniques like voltage scaling, variable-rate sampling (VRS) has been exposed as an adequate possibility to minimize the transceiver activity [1]. In this paper a high performance algorithm based on an artificial neural network...
Since Multiple Input Multiple Output (MIMO) transmission has become more and more popular for current and future mobile communication systems, MIMO detection is a big issue. Linear detection algorithms are less complex and well understood but their BER performance is limited. ML detectors achieve the optimum result but have exponential computational complexity. Hence, iterative tree-search algorithms...
Basic Demand response (DR) programs aim to modulate the demand of electricity in accordance with its supply. The existing DR programs have only been of limited success, though the participation has steadily increased in the recent past. This paper establishes the lack of fairness principles within the DR programs, as perceived by the customers to be one of the key deterrents. Fair DR (FDR) scheme...
Gene selection from microarray data is an important issue for gene expression based classification and to carry out a diagnostic test. In this regard, a rough set based gene selection algorithm is presented. It selects the set of genes by maximizing the relevance and significance of the genes, which are calculated based on the theory of rough sets. Using the predictive accuracy of K-nearest neighbor...
In modern power system operation the optimization problem and voltage stability problem are two interrelated issues. This paper presents a new methodology to assess system voltage stability status combined with optimal power flow technique using instantaneous two-bus π-equivalent model of a power system at different operating conditions. Thyristor controlled series compensator (TCSC), one of the popularly...
We present a new Internet architecture based on de-conflated identities (ADI) that explicitly establishes the separation of ownership of hosts from the underlying infrastructure connectivity. A direct impact of this de-conflated Internet architecture is the ability to express organizational policies separately and thus more naturally, from the underlying infrastructure routing policies. Host or organizational...
