The use of radio frequency identification (RFID) allows utility companies to read meters from a distance. Thus a meter reader need not visit every customer on his route, but only get within a certain radius of each customer. In finding an optimal route – one that minimizes the distance the meter reader travels while servicing each customer on his route – this notion of only needing to be close ...

The Q-depth relation in the earth's mantle has been estimated for long-period P waves from two deep-focus and three intermediate earthquakes. The amplitude spectrums of the first P waves from 114 seismograms at recording stations inthe distance range between 15 and 103 degrees, have been corrected for the crustal structure and the instrument and used to measure the effects of attenuation ver th...

BACKGROUND To explain the possible effects of exposure to weather conditions on population health outcomes, weather data need to be calculated at a level in space and time that is appropriate for the health data. There are various ways of estimating exposure values from raw data collected at weather stations but the rationale for using one technique rather than another; the significance of the ...

OBJECTIVES The aim of our study was to assess the health conditions and subjective symptoms of the inhabitants living in the base stations vicinity and to analyse the relationship between the complaints and level of exposure to electromagnetic fields (EMF). MATERIALS AND METHODS Our study was performed in housing estates located in five regions of Łódź. The electric field measurements were pe...

Background. The objective of this trial was to evaluate the effect of two exercise programs on patients undergoing the implantation of intraarticular stem cells. Objectives. We performed a randomized trial on sixteen patients under 65 years old with moderate knee OA after stem cell therapy. Methods. Patients were randomly divided into two groups of exercise therapy: weight-bearing (WB) and no...

⎯ This paper presents a model-based Register Transfer Level (RTL) design of a 4x2 Multiple-Inputs Multiple-Outputs (MIMO)-Orthogonal Frequency Domain Multiplexing (OFDM) wireless communication systems transmitter and its Field Programmable Gate Array (FPGA) implementation. This system provides a maximum of 600 Mbps with 20 meter of propagation distance using 80 MHz baseband bandwidth with 4x2 M...

We undertook a long term project, DIRECT, to obtain the direct distances to two important galaxies in the cosmological distance ladder – M31 and M33, using detached eclipsing binaries (DEBs) and Cepheids. While rare and difficult to detect, detached eclipsing binaries provide us with the potential to determine these distances with an accuracy better than 5%. The massive photometry obtained in o...

this study was conducted to identify drought event and its emerging regions in markazi desert, iran with focus onsemnan province in a 30 years statistical period. in this research, 61 stations having adequate data selected and usedafter extracting annual statistic from monthly and daily data. standardized precipitation index values for each stationwere calculated and classified. the results hav...

The ability to reach a high running velocity over a short distance is essential to a high playing performance in team games. The aim of this study was to determine the relationship between running time over a 10-meter section of a 30-meter sprint along a straight line and changes in the angle and angular velocity that were observed in the ankle, knee, and hip joints. The possible presence may h...
