The main features of RFID are the ability to identify objects without a line of sight between reader and tag, read/write capability and ability of readers to read many tags at the same time. The read/write capability allows information to be stored in the tags embedded in the objects as it travels through a system. Some applications require information to be stored in the tag and be retrieved b...

We investigate the psychophysical and computational processes underlying the perception of depth from texture cues in perspective projections. In particular, we analyse the similarities between the processes associated with perspective and orthographic projections. Based on a series of psychophysical experiments using white noise stimuli presented in perspective projection, we suggest that the ...

-A new control method for single-phase shunt active power filter (APF) is proposed. It integrates the DC bus voltage control and active power filter command current generation, according to the periodicity of source current and energy balance concept. The instantaneous harmonic compensation and linear DC bus voltage control are achieved, without complicated and involved control logic, by using ...

A new general framework for agent cooperation and coordination in solving distributed constraint satisfaction problems (DCSPs) is presented. The Asynchronous Partitioning Framework (APF) first partitions agents into groups of agents, based on some heuristic, prior to any search being conducted. During the partitioning one of the agents in each group is assigned the role of a group leader. Next,...

Opisthorchis viverrini infection induces chronic inflammation, and a minor proportion of infected individuals develop advanced periductal fibrosis (APF) and cholangiocarcinoma (CCA). Inflammatory cytokines and/or their gene polymorphisms may link to these biliary pathologies. We therefore investigated associations among cytokine gene polymorphisms and cytokine production in 510 Thai cases infec...

BACKGROUND Interstitial cystitis (IC) is a chronic bladder disorder, with symptoms including pelvic and or perineal pain, urinary frequency, and urgency. The etiology of IC is unknown, but sensitive and specific biomarkers have been described, including antiproliferative factor (APF), heparin-binding epidermal growth factor-like growth factor (HB-EGF), and epidermal growth factor (EGF). However...

The purpose of this in vitro study was to determine the combined effects of argon laser irradiation (ArI) and acidulated phosphate fluoride treatment (APF) on caries-like lesion formation in human enamel. Each specimen was divided into tooth quarters with each quarter assigned to one of four groups: 1) control; 2) ArI Only; 3) ArI before APF treatment; 4) APF treatment before ArI. After a fluor...

AIM The aim of the study was to correlate the pH and fluoride ion uptake with surface hardness of composite resin based restorative materials after topical fluoride application. METHODOLOGY Forty disks of each of test materials Composite (Filtek Z350XT, 3M ESPE, St Paul, MN, USA), Resin modified glass ionomer (Vitremer) and Compomer (Dyract AP) were made and ten disks of each material were pl...

It has been established that shunt active power filters are suitable for compensating harmonics in the current fed type harmonic producing loads, likewise the series active power filter (APF) are considered to be suitable for voltage fed type harmonics-producing load. This paper discusses the indirect current control approach in terms of its simplicity and effectiveness for the operation of a s...
