Analysis of human behavioral patterns
PublikacjaWidespread usage of Internet and mobile devices entailed growing requirements concerning security which in turn brought about development of biometric methods. However, a specially designed biometric system may infer more about users than just verifying their identity. Proper analysis of users’ characteristics may also tell much about their skills, preferences, feelings. This chapter presents biometric methods applied in several...

Performance analysis of an rfid-based 3d indoor positioning system combining scene analysis and neural network methods
PublikacjaThe main purpose of this research is to improve localization accuracy of an active Radio Frequency Identification, RFID tag, in 3D indoor space. The paper presents a new RFID based 3D Indoor Positioning System which shows performance improvement. The proposed positioning system combines two methods: the Scene Analysis technique and Artificial Neural Network. The results of both simulation using Log-Distance Path Loss Model and...

Preparation and characterization of Pt/Pd-modified titanium dioxidenanoparticles for visible light irradiation
PublikacjaSeries of Pt/Pd–TiO2photocatalysts were obtained using the sol–gel method. The Pt/Pd–TiO2nanocom-posites showed significant visible light photoactivity. X-ray diffraction, STEM microscopy, UV–visspectroscopy and BET characterization allowed to conclude that the photocatalysts at the best perfor-mance had the anatase structure, 91 m2/g specific surface area, Pt/Pd alloy structure and 1–4 nm particlesize. The photocatalytic activity...

Spectroelectrochemical characteristics of poly(3,4-ethylenedioxythiophene) / iron hexacyanoferrate film-modified electrodes
PublikacjaPraca dotyczy pomiarów spektroelektrochemicznych materiałów hybrydowych złożonych z polimeru elektroaktywnego poli(3,4-etylenodioksytiofenu) i Błękitu Pruskiego. Dla porównania badano również filmy polimerowe z wybranymi przeciwjonami: heksacyjanożelazowym (Fe(CN)63-/4-), chlorkowym (Cl-) i polistyrenosulfonowym (PSS-). Materiały w postaci cienkich filmów otrzymano na elektrodzie szklanej pokrytej tlenkiem indowo-cynowym. Widma...

Preparation and photocatalytic activity of boron-modified TiO2 under UV and visible light
PublikacjaOtrzymano TiO2 domieszkowany borem i wyznaczono jego aktywność fotokatalityczną w zakresie światła UV i Vis. Katalizatory otrzymano metodą zol-żel lub poprzez ucieranie dwutlenku tytanu z prekursorami B. Jako źródło boru zastosowano kwas borowy lub ester trietylowy kwasu borowego. Fotoaktywność próbek badano w reakcji degradacji fenolu (Co = 0,21 mmol/dm3 ) w zakresie światła Vis lub UV. Obecność węgla i boru we wszystkich przygotowanych...
