This paper proposes a novel received signal strength indicator (RSSI)-based self-adaptive indoor positioning algorithm which can be utilized in non-line-of-sight (LOS) environments through the employment of a weighted feedback framework. This algorithm is composed of the following parts: optimized RSSI algorithm, offset-triangulation algorithm and weighted feedback framework. The developed self...

The δ-Matching problem calculates, for a given text T1..n and a pattern P1..m on an alphabet of integers, the list of all indices Iδ = {i : maxmj=1 |Pj − Ti+j−1| ≤ δ}. The γ-Matching problem computes, for given T and P , the list of all indices Iγ = {i : P m j=1 |Pj − Ti+j−1| ≤ γ}. When a “don’t care” symbol occurs, the associated difference is counted as zero. In this paper, we give experiment...

This paper presents accelerated lifetime tests on a polypropylene film capacitor. Experimental parameters (20% droop, 5 Hz repetition rate) simulate anticipated operating conditions encountered in the SLAC P2 Marx. Elevated film electric field stress is utilized as the acceleration parameter. Results indicate that, for the particular film of interest, a film stress of ~290 V/μm corresponds to a...

Low power and robust circuitry are permanent hotspots in VLSI design. Adiabatic logic is one of potential breakthroughs for these goals. Especially, designing reliable clock tree is very significant for adiabatic logic due to four-phase clocked power required for pipelined data transmission in adiabatic system. In this paper, we present analysis of charging speed and clock types that influence ...

Stochastic anti-resonance, that is resonant enhancement of randomness caused by polarization mode beatings, is analyzed both numerically and analytically on an example of fibre Raman amplifier with randomly varying birefringence. As a result of such anti-resonance, the polarization mode dispersion growth causes an escape of the signal state of polarization from a metastable state corresponding ...

This paper presents a parallel genetic algorithm for the job shop scheduling problem (JSP). There are following innovations in this new algorithm: active schedules are created by the priority rules of Giffler and Thompson; the mutation uses neighborhood searching techniques; the crossover uses GT algorithm and is performed on 3 parents. The convergence of the algorithm is also shown in this pap...

Wireless sensor networks for outdoor applications, such as habitat monitoring, are expected to require wireless link ranges that are longer than achievable with commonly available platforms. We discuss ways to extend link range within the constraints typical of wireless sensor networks and incorporate these aspects into the design of a wireless module. We report on the use of this module in a w...

Text Document classification aims in associating one or more predefined categories based on the likelihood suggested by the training set of labeled documents. Many machine learning algorithms play a vital role in training the system with predefined categories among which Naïve Bayes has some intriguing facts that it is simple, easy to implement and draws better accuracy in large datasets in spi...
