Location information of sensor nodes has become an essential part of many applications in Wireless Sensor Networks (WSN). The importance of location estimation and object tracking has made them the target of many security attacks. Various methods have tried to provide location information with high accuracy, while lots of them have neglected the fact that WSNs may be deployed in hostile environ...

In this paper I will give a model-theoretic account for structural realism. I will introduce the so-called ‘hierarchy of models’ which can be used to formally analyse the structure shared by a ‘high-level theory’ and the ‘phenomena’. I will show that structural empiricism (as characterized by Bueno (1997, 2000) and Van Fraassen (1980)) cannot be accommodated in the hierarchy of models and show ...

Background and Aims: The rate of urinary tract infection caused by the extended-spectrum-β-lactamase- (ESBL) producing Escherichia coli (E. coli) is increasing worldwide. This study aimed to assess the frequency of blaCTX-M genes in the E. coli isolated from urinary tract infection (UTI) in outpatients. Methods: 240 E. coli bacteria were isolated from the outpatients’ urine samples in the Kerma...

ABSTRACT Small UAV performance is limited by the sensors and software filters used in the navigational systems. Several solutions of various complexity and cost exist, however no ready-made solutions exist for a high-accuracy, low-cost UAV system. Presented is the design (low-level system as well as high-level extended Kalman filter) for a specifically designed small-UAV navigation platform, Ag...

Within this contribution, we will introduce the so called Smart Grid Architecture Model (SGAM) which has been developed in the European Commissions’ M/490 mandate. After having proved successful in dozens of projects and especially standardization, the SGAM can be considered as state of the art to document smart grid architectures on a high level. However, as electric mobility is a part of the ...

A large number of candidates have become a regular feature of Indian elections. Given the regulatory concerns the problem has evoked, the paper reviews the process of candidate entry in select developed countries. The review reveals the presence of diverse approaches, ruling out the necessity for extreme options like debarring fringe candidates – a course suggested by several Indian expert grou...

This paper presents a new approach for the classification of pathological vs. healthy endomicroscopic images of the alveoli. These images, never seen before, require an adequate description. We investigate two types of feature vector for discrimination: a high-level feature vector based on visual analysis of the images, and a pixel-based, generic feature vector, based on Local Binary Patterns (...

A multitone tracker is described using two basic principles in optimum frequency estimation, namely: Processing bandwidth depending on the distance from the estimate to the actual frequency values; and, parallel estimates with inhibitory paths to ensure orthogonality between the enhanced tones. The first feature is provided by Extended Kalman Filters (EKF), and the second one is achieved by hig...

Abstract: In recent decades, high profits of extended warranty have caused that third-party firms consider it as a lucrative after-sales service. However, customers division in terms of risk aversion and effect of offering extended warranty on manufacturers’ basic warranty should be investigated through adjusting such services. Since risk-averse customers welcome extended warranty, while the cu...
