Multiple-input multiple-output (MIMO) Rayleigh fading channel with truncated Laplacian azimuth power spectrum (APS) is studied. By using the power correlation matrix of MIMO channel model and the modified Jakes simulator, into which random phases are inserted, the effect of the azimuth spread (AS), angle of departure (AOD) and angle of arrival (AOA) on the spatial correlation coefficient and ch...

background & aim: this experiment was conducted to examine the effect of different levels of echinacea purpurea (ep) in comparison with an antibiotic (flavofosfolipol) on total antioxidant activity (aoa) in serum of broiler chicks. experimental: in this trial 240 one-day-old broiler chicks (ross 308) were weighed and randomly assigned to the 5 treatment groups, each with 4 replicates with 1...

This study investigates age of acquisition (AoA) and word frequency effects in both spoken and written picture naming. In the first two experiments, reliable AoA effects on object naming speed, with objective word frequency controlled for, were found in both spoken (Experiment 1) and written picture naming (Experiment 2). In contrast, no reliable objective word frequency effects were observed o...

The American Osteopathic Association Commission on Osteopathic College Accreditation (AOA COCA) is recognized by the US Secretary of Education as the only accrediting agency for osteopathic predoctoral education. To maintain its recognition with the US Secretary of Education, the AOA COCA is required to adhere to all federal laws and regulations associated with the recognition of accrediting ag...

The distribution of ammonia-oxidizing archaea (AOA) and bacteria (AOB) in cattle, swine, and chicken manure compost was analyzed. PCR-denaturing gradient gel electrophoresis (DGGE) showed that a Candidatus Nitrososphaera gargensis-like sequence dominated in cattle manure compost, while few AOA were detected in other composts. In the case of AOB, Nitrosomonas-like sequences were detected with hi...

The launch of Osteopathic Continuous Certification (OCC) signifes the next stage of the osteopathic board certification process. The OCC process replaces the old recertification system for all osteopathic physicians who earned time-limited certificates from American Osteopathic Association (AOA) certifying boards. All 18 AOA certifying boards are now engaged in the continuous certification proc...

The American Osteopathic Association Commission on Osteopathic College Accreditation (AOA COCA) is recognized by the US Secretary of Education as the only accrediting agency for predoctoral osteopathic medical education. To maintain its recognition with the US Secretary of Education, AOA COCA is required to adhere to all federal laws and regulations associated with recognition of accrediting ag...

—To reduce the theft rate of smart phones, laptops and tablets in public, this paper proposes a novel network based anti-theft alert system using a dynamic hybrid time of arrival (TOA)/angle of arrival (AOA) algorithm. Specifically, the statistic weights of the results produced by the TOA and AOA methods are dynamically varied according to the signal propagation environment. In this way the co...

Angle of arrival (AOA) is able to achieve high accuracy when the antenna arrays are deployed much closer to the emitter. However, spatial resolution problem still exists. This paper presents a novel AOA estimation method called sparsity angle sensing (SAS) to improve the resolution. It integrates compressive sensing theorem into the parameter estimation formula. Traditional approaches for AOA e...

Location finding for CDMA subscribers using an antenna m a y at the base station is studied in this paper. Two methods are considered for radio location that are based on time of arrival (TOA) and angle of arrival (AOA) measurements. For TOA estimates, a maximum likelihood algorithm and a practical structure are proposed when an antenna array is available. For AOA estimates, a least-squares (LS...
