Efficiency analysis of sonic drilling wells and the choice rational operational modes drill bit vibration loading to increase rate penetration was carried out. The are studied on basis an assessment power process with a cavitation hydrovibrator. This paper presents approach calculating mechanical oscillatory bit. uses developed mathematical model dynamics hydraulic vibrator string. describes in...

An electrolarynx, a verbal communication aid used by laryngectomy patients, is a vibrator held against the neck tissue to provide excitation to the vocal tract, as a substitute to that provided by the glottal vibrations. Although the user can set the vibration level and pitch, a dynamic control of level, voicing, and pitch during speech production is not feasible. In addition to this basic limi...

Shear-wave vibrator is a type of equipment usually employed for natural gas exploration, consisting vibrating machine which applies dynamic loads to the surrounding soils in order ease extraction gas. Detailed numerical simulations these devices are scarce literature. Thus, this paper, nonlinear 3D finite element simulation has been conducted investigate main features response vibrator. Nonline...

A series of five experiments were performed to test a general theoretical model which conceptualizes the sensory prominence of various body sectors as providing persistent peripheral signals which can modify central perceptual and fantasy processes. Two experiments involved stimulation of right versus left and front versus back body sites by means of a vibrator and determining the effects upon ...

The short answers to your questions are that yes, condoms can be used for masturbation, and no, it doesn't need to be a waste. Choosing to use condoms [2] during masturbation [3] might be based on several factors, including how you masturbate and what you hope to get out of the activity. For example, are you using a toy (such as a vibrator or dildo) or are you letting your fingers do the walkin...

Machining pieces with cylindrical symmetry are realized through classic processes for example turning, mortising, etc or recently through no conventional methods, for example vibrorolling and vibrofinishing. Solution adopted by the authors to realize vibrorolling equipment are composed of one electromagnetic vibrator with two coils out of time operating, static contactors with transistors for d...
