The leaf spring is widely used in automobiles and one of the components of suspension system. It needs to have excellent fatigue life. As a general rule, the leaf spring must be regarded as a safety component as failure could lead to severe accidents. The purpose of this paper is to predict the fatigue life of semi-elliptical steel leaf spring along with analytical stress and deflection calcula...
The purpose of this study is to produce a groundwater spring potential map based on statistical and probability logistic regression method. The spatial locations of the springs in mountainous Miradeh watershed, Kurdistan province, with 381 Km2 were determined. Based on field and local study and Water Resources Management Company, spatial location of 904 springs in the study area were registered...
In this paper different conservative models of tethered satellites are related mathematically and it is established in what limit they may provide useful insight into the underlying dynamics. An infinite dimensional model is linked to a finite dimensional model, the slack-spring model, through a conjecture on the singular perturbation of tether thickness. The slack-spring model is then naturall...
Series Elastic Actuators have linear springs intentionally placed in series between the motor and actuator output. The spring strain is measured to get an accurate estimate of force. Despite using a transmission to achieve high force/mass and high power/mass, the spring allows for good force control, high force fidelity, minimum impedance, and large dynamic range. A second order linear actuator...
While the wing kinematics of many flapping insects have been well characterized, understanding the underlying sensory, neural, and physiological mechanisms that determine these kinematics is still a challenge. Two main difficulties in understanding the physiological mechanisms arise from the complexity of the interaction between a flapping wing and its own unsteady flow, as well as the intricat...
abstract the present study was conducted to investigate the effect of using model essays on the development of writing proficiency of iranian pre-intermediate efl learners. to fulfill the purpose of the study, 55 pre- intermediate learners of parsa language institute were chosen by means of administering proficiency test. based on the results of the pretest, two matched groups, one as the expe...
springs are the mechanical parts which have many application in industries. static and dynamic forces cause relaxation in these parts so that they lose some of their free length and reaction force. springs constant are very important in airplane and vailway industry since constant and variable forces are applied to them in period time, therefore it is necessary to avoid decreasing in spring co...
An experimental speech recognition system was developed for German using an already existing technology reported elsewhere (1). The system recognizes complete sentences when the words are spoken with a small pause in between. The user has to train the system in advance by uttering 110 short sentences. The size of the system's vocabulary is presently limited to about 1300 words, with a coverage ...
THE1974 ARTICLE BY Line and Sandison entitled “ ‘Obsolescence’ and Changes in the Use of Literature with Time” was highly critical of many assumptions about obsolescence and of the methodology and conclusions of much research on the topic. It placed emphasis on the distinction between synchronous and diachronous studies and on the need to correct for the size of the literature cited or used. Si...
