ultra-wideband (uwb) radio is a promising technology for low-cost, high-rate communications at short ranges. however, high bandwidth and low power of the uwb signals impose some difficult challenges in signal processing and implementation of the receiver. acquisition of the signal timing is the first task to be performed in a coherent receiver. the high bandwidth of uwb signals demand for fine ...

the purpose of the present study was to examine the effects of self – control modeling , that is presenting moded to learner whenever they asked for it, on learning a timing task.twenty four right handed subjects (12 males, 12 females, aged 19-20) voluntarily participated in the study and were assigned randomly to two groups of self – control and yoked.the task was pressing the keys number 1, 4...

Information freshness and high energy-efficiency are key requirements for sensor nodes serving Industrial Internet of Things (IIoT) applications, where a sink node must collect informative data before deadline to control an external element. Pull-based communication is interesting approach optimizing information saving wasteful energy. To this end, we apply Content-based Wake-up (CoWu), in whic...

one pollutant which seriously threatens water resources is dye. therefore, finding a suitable method to separate the dye in water resources is very important. an adsorption process that uses low cost adsorbents is considered as an efficient strategy for this purpose. in this study, erythrosine dye removal from an aquatic environment using natural absorbents, namely sorghum and ziziphus nummular...

This paper presents a systematic methodology for the design of distributed fault tolerant real-time systems. The methodology covers the stepwise reenement of the given requirements, expressed in the form of real-time transactions, to task and protocol executions. It also includes a timing analysis and dependability evaluation of the still incomplete design. The testability of the evolving syste...

Nitrogen (N) application management needs to be refined for low yielding environments under dryland conditions. This 3-yr study examined nitrogen fertilization management effects on corn (Zea mays L.) plant characteristics and grain yield in rain fed environment under conventional tillage system. Nitrogen fertilization management consisted of two timing methods of N application [all N at planti...
