In this paper, the experimental vibration analysis of a single cylinder air compressor based on a hypocycloid straight line mechanism (HSM) is investigated. The HSM mechanism uses planetary gears to convert rotational motion to purely linear motion. In the conventional air compressor, the slider- crank mechanism is replaced by the HSM mechanism with appropriate counterweights. The constructed s...

In this paper we present results that indicate that the formant frequencies between di erent speakers scale di erently at di erent frequencies. Based on our experiments on speech data, we then numerically compute a universal frequencywarping function, to make the scale-factor independent of frequency in the warped domain. The proposed warping function is found to be similar to the mel-scale, wh...

Psycho-oncology is an interdisciplinary field of medicine that deals with the psychological aspects of cancer. Psycho-oncology is a sub-discipline of clinical oncology, psychiatry, clinical psychology and health psychology. It was formally established in 1975. In Poland, the Polish Psycho-Oncology Association deals with the issues of psycho-oncology since 1992. Despite the dynamic development o...

Objectives: Analysis of variations of nutritional status in relation to psycho-functional conditions in elderly patients with mild to moderate Alzheimer’s disease (AD) by means of bioelectrical impedance vector analysis (BIVA). Design: Cross-sectional study. Setting: Alzheimer Center, SS. Trinità Hospital, Cagliari (Italy). Participants: 83 free-living patients (29 men, 54 women) with mild-mode...

Introduction. The profession of psycho-oncologist in Poland is not sufficiently regulated by law. Current solutions the system involve contradictory regulations on obtaining qualifications to practice, which produces effect systemic chaos and result limited availability services provided oncology patients their families practitioners this demanding profession.

BACKGROUND In April 2011, a post election violent conflict in Northern Nigeria led to resettlement of internally displaced persons (IDPs) in a camp in Kaduna, the worst affected state. We set out to determine prevalence and socio-demographic factors associated with post-traumatic stress disorder (PTSD) among IDPs. We also determined types of psycho-trauma experienced by the IDPs and their psych...

Many experiments in architectural acoustics require presenting listeners with simulations of different rooms to compare. Acoustic scale modeling is a feasible means to create accurate simulations of many rooms at reasonable cost. A critical component in a scale model room simulation is a receiver that properly emulates a human receiver. For this purpose, a scale model artificial head has been c...
