this research is carried out to design and manufacturing of lathe vibration tool and their tests. firstly, one-dimensional vibration tool is designed and made of the bending vibration mode. one-dimensional vibration tool with half piezoelectric rings is considered to excite the bending mode of tool. structure of vibration tool is designed in abaqus software about 20 khz and then is made with re...
background: deficiency of attention and concentration is one of great reasons of traffic incidents and it covers between 20 to 50 percent of events due to careless and mindedness. studies show that attention and concentration are considered as one of important cognitive components in safe driving. vibration is an important physical effect in all vehicles. till now has not been any organized stu...
in this paper, we propose a new full-fuzzy video ratecontrol algorithm (rca) for variable bit rate (vbr) videoapplications. the proposed rca provides high qualitycompressed video with a low degree computational complexity.by controlling the quantization parameter (qp) on a picturebasis, it produces vbr video bit streams. the proposed rcahas been implemented on the jm h.264/avc video codec andth...
Design of the 12-bit Delta-Sigma Modulator using SC Technique for Vibration Sensor Output Processing
The work deals with the design of the 12-bit Delta-Sigma () modulator using switched capacitors (SC) technique. The modulator serves to vibration sensor output processing. The first part describes the modulator parameters definition. Results of the proposed topology ideal model were presented as well. Next, the modulator circuitry on the transistor level was done. The ONSemiconductor I...
A rate control algorithm at the group of picture (GOP) level is proposed in this paper for variable bit rate applications of the H.265/HEVC video coding standard with buffer constraint. Due to structural changes in the HEVC compared to the previous standards, new rate control algorithms are needed to be designed. In the proposed algorithm, quantization parameter (QP) of each GOP is obtained by ...
پایش پیوسته ی سلامت ساختاری مبتنی بر امپدانس/ادمیتانس الکترومکانیکی به روش پوشش دهی فیلم ضخیم فعّال پیزوالکتریک به منظور تشخیص پیدایش آسیب در ساختارهای فلزی، غیرفلزی و سوپرآلیاژ در شرایط ساکن و متحرّک مورد بررسی قرار گرفته است. این روش یکی از موثرترین راهکارهای پیش بینی آسیب، ارتقای سطح ایمنی، کاهش هزینه ها و بررسی طول عمر قطعات صنعتی در سازه های مختلف از جمله توربوفن ها، کمپرسورها، رآکتورها، تور...
in future high-speed self-routing photonic networks based on all-optical time division multiplexing (otdm) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. in this paper we propose a self-routing otdm node structure composed of an all-optical router and demultiplex...
