Collaborative beamforming has already demonstrated its potential of significant power savings in distributed sensor networks. In collaborative beamforming, the antennas of the sensor nodes form a distributed antenna array in an effort to direct the radiated energy to the desired direction and thus increase the overall power efficiency of the network.(More)
OBJECTIVES Study of overweight and obesity among women from modest neighborhoods in Casablanca and the related factors influencing this phenomenon. DESIGN A survey was conducted in 6 neighborhoods of Casablanca using multistage cluster sampling. Anthropometric parameters and body composition were measured, and information about food habits,(More)
The complexity of nonlinear differential equations of dynamics makes it practically impossible to obtain the walk pattern on-line through computing the whole dynamics. This paper proposed a method of online trajectory generation based on key parameters of off-line typical walk patterns for a biped humanoid. The key parameters include hip parameters, step(More)
In this paper, a method is proposed for humanoid robots performing object transfering task in a teleoperated cooperative paradigm. The cooperative task is accomplished using simple communication among two humanoid robots and then switch between modes according to the situation. In case of object passing with two humanoid robots, mutual position shifts may(More)
Objective: The radiation dosimetry is the output measurement of radiation generating source/ machine and its ambition is to ensure that the teletherapy units’ outputs are within limits. In the current article, the dosimetry of Cobalt-60 (Co 60 ) teletherapy units at Nuclear Institute of Medicine and Radiotherapy (NIMRA), Jamshoro Pakistan was studied. As Co(More)
This study aimed to assess the effect of virgin argan oil (VAO) and extra virgin olive oil (EVO) on the hormonal profile of androgens and anthropometric parameters among healthy adult Moroccan men during a controlled nutritional intervention. The study was carried out on 60 young and healthy male volunteers aged between 23 and 40 years old. During a(More)
In teleoperation system, the tracking ability is reduced due to the existence of time delay in communication channel, as communication delay can degrade the performance and destabilize the system. In this paper, a particular control scheme, the quasi-linear minimal order feedback controller have been proposed to control bilateral teleoperation, which is(More)
of this pilot study was to estimate the salt intake of Moroccan adults by measuring 24-hour urinary sodium excretion. Methods: 132 participants were recruited from the central region of Morocco. Sodium, potassium and creatinine levels were measured using the 24-hour urine samples. Additional data included anthropometric measurements and socio-demographic(More)
