Modeling, Design and Experimentation of Wearable RFID Sensor Tag
2010
Design of effective wearable tags for UHF RFID applications involving persons is still an open challenge due to the strong interaction of the antenna with the human body which is responsible of impedance detuning and efficiency degradation. A new tag geometry combining folded conductors and tuning slots is here discussed through numerical analysis and extensive experimentation also including the integration of a passive motion detector. The achieved designs, having size comparable with a credit card, may be applied to any part of the body. The measured performance indicates a possible application of these body-worn tags for the continuous tracking of human movements in a conventional room.
Intruder Pattern Identification
2008
This paper considers the problem of intrusion detection in information systems as a classification problem. In particular the case of masquerader is treated. This kind of intrusion is one of the more difficult to discover because it may attack already open user sessions. Moreover, this problem is complex because of the large variability of user models and the lack of available data for the learning purpose. Here, flexible and robust similarity measures, suitable also for non-numeric data, are defined, they will be incorporated on a one-class training K N N and compared with several classification methods proposed in the literature using the Masquerading User Data set (www.schonlau.net) repr…
Implementation and performance of the ATLAS second level jet trigger
2008
ATLAS is one of the four major LHC experiments, designed to cover a wide range of physics topics. In order to cope with a rate of 40 MHz and 25 interactions per bunch crossing, the ATLAS trigger system is divided in three different levels. The first one (LVL1, hardware based) identifies signatures in 2 microseconds that are confirmed by the the following trigger levels (software based). The Second Level Trigger (LVL2) only looks at a region of the space around the LVL1 signature (called Region of Interest or ROI), confirming/rejecting the event in about 10 ms, while the Event Filter (Third Level Trigger, EF) has potential full event access and larger processing times, of the order of 1 s. T…
APPLICATION OF ADAPTIVE WAVELET NETWORKS FOR VIBRATION CONTROL OF BASE ISOLATED STRUCTURES
2010
Accepted version of an article from the journal: International Journal of Wavelets, Multiresolution & Information Processing. Official version article published as International Journal of Wavelets, Multiresolution & Information Processing, 2010 8(5), 773-791. doi: 10.1142/s0219691310003778 © World Scientific Publishing Company http:// http://www.worldscinet.com/ijwmip/ This paper presents an application of wavelet networks (WNs) in identification and control design for a class of structures equipped with a type of semiactive actuators, which are called magnetorheological (MR) dampers. The nonlinear model is identified based on a WN framework. Based on the technique of feedback linearizatio…
Landing gear suspension control through adaptive backstepping techniques with H∞ performance
2011
Author's version of a chapter published in the book: Proceedings of the 18th IFAC World Congress 2011. Also available from the publisher at: http://dx.doi.org/10.3182/20110828-6-IT-1002.00589 Landing gear suspension systems fulfill the tasks of absorbing the vertical energy of the touch-down as well as providing passenger and crew comfort with a smooth ground ride before take-off and after landing. They are also designed to have optimal performance in the case of a hard landing. In general, the tasks of aircraft landing gears are complex and sometimes lead to a number of contradictory requirements. Although there are existing modifications of aircraft shock absorbers to reduce the problem, …

Radiofrekvences identifikācijas izmantošana laika izsekošanai sporta sacensībās
2016
Diplomdarbā tiek analizētas pasīvo RFID etiķešu izmaksu samazinājuma potenciāls kā iespēja biznesa veidošanai. Specifiski, lai skriešanas sacensību “Stirnu Buks” organizatoram varētu piedāvātu izdevīgāku laika izsekošanas tehnoloģiju par pašreizējo ārpakalpojuma sniedzēju - SPORTident. Darba rezultātā tiek secināts, ka ir iespējams piedāvāt pasīvo laika izsekošanas sistēmu lētāk par pašreizējo konkurentu un gūt sākotnēji plānoto peļņu. Tajā pašā laikā atšķirība no konkurenta piedāvātās cenas ir pietiekoši neliela, lai apšaubītu klienta vēlmi mainīt pakalpojuma sniedzēju. Piedāvātā pakalpojuma cenas samazināšana gadījumā mērķa peļņa netiek sasniegta un tiek secināts, ka tādā gadījumā piegādā…
Kalambūri Oskara Vailda komēdijā “Cik svarīgi būt nopietnam”
2017
Dramaturģija tiek pētīta lingivistikas kontekstā relatīvi īsu laiku un nav veikti daudz pētījumi par kalambūru izmantojumu Oskara Vailda komēdijā ‘Cik Svarīgi Būt Nopietnam’. Kalambūri ir izteikts komiskā efekta radīšanas instruments lugā, un šis darbs analizē to izmantojumu katram Vailda lugas ‘Cik Svarīgi Būt Nopietnam’ tēlam, kā arī pēta kalambūru radīto efektu saistībā ar tēlu prezentēšanu. Lai identificētu kalabūrus, tie ir uzskatīti par frazeoloģiskām vienībām, līdz ar to Nacisciones frazeoloģisko vienību identificēšanas process ir izmantots pētījumā. Sekojoši, Nash izstrādātā kalambūru taksonomija ir pielāgota un izmantota kalambūru klasificēšanai lugā, ar mērķi salīdzināt dažādus ka…
Perceived collective continuity and ingroup identification as defence against death awareness
2008
"Perhaps unique among the animal species, humans are aware that they will ultimately die. Terror management theory (TMT) posits that investing in a social group helps people to manage paralysing anxiety stemming from death awareness. In line with this proposition, research to date has shown that when reminded of their own mortality, people increase their identification with a relevant group and defend its beliefs, values, and practices. In the reported study, we demonstrate that a mortality salience induction enhances people’s perceptions of group temporal endurance—or perceived collective continuity (PCC), as we define it. Enhanced PCC leads, in turn, to enhanced group identification. This…
Infants and Children Making Sense of Scents
2017
This chapter summarizes research on the development of human olfactory skills to rely on different cues conveyed by odorants, such as odor quality, intensity, position in space, novelty/familiarity, and hedonic value. The sensory, neural, and psychological dimensions at the root of these early aptitudes remain poorly explored in humans, but one can safely affirm that any weak odor to which the infant has previously been nonadversely exposed will have a higher reinforcing value than any novel odor. Developmental differences in odor discrimination and appreciation are certainly causally multiple and may depend on general or olfaction-specific cognitive factors which can be traced back to pren…
