automation of tractors due to their widespread use in different sectors e.g. agriculture, construction and industry have been seriously considered by researchers. in this study a tele-steering system for tractor was designed and constructed to controling and steering so the operator can control the tractor even far away from the stressful condition of tractor cab, . a cctv camera and an electri...

background isolated small gut mesentery injury after blunt abdominal trauma from the steering wheel in road traffic accidents is rare. these are always challenging to diagnose and pose a diagnostic dilemma. objectives to study the pattern of small gut mesenteric injury by steering wheel blunt abdominal trauma in road traffic accidents in patients who had laparotomy. patients and methods a 10-ye...

In this paper, kinetic and kinematic modeling of a 4 wheel steering vehicle is done and its movement is controlled in an optimal way using Linear Quadratic Regulator (LQR). The results are compared with the same control of two-wheel steering case and the advantages are analyzed. In 4 wheel steering vehicles which are nowadays more applicable the number of controlling actuators are more than the...

Direct damage to the pancreas occurs in about 5YO of closed abdominal injuries, many of which arise from major accidents. The fixed retro-peritoneal site of the pancreas makes it particularly vulnerable to trauma by the steering column in cars not being constructed to modem safety requirements. As these injuries become more common, and as the number of survivors of such trauma increases, the lo...

A reference generation scheme is proposed for a 1T-1C ferroelectric random-access memory (FeRAM) architecture that balances fatigue evenly between memory cells and reference cells. This is achieved by including a reference cell per row (instead of per column) of the memory array. The proposed scheme converts the bitline voltage to current and compares this current against a reference current us...

The released ISO 26262 standard for automotive systems requires several validation and verification activities. These validation and verification activities have to be planned and performed jointly by the OEMs and the suppliers. In this paper, we present a systematic, structured and model-based method to plan the required validation and verification activities and collect the results. Planning ...

The study of rotary steering drilling technology is currently one of the hot topics in the drilling engineering field. It requires accurate well trajectory control instructions when rotary steerable tools are applied to achieve the well trajectory control goal. A drilling trajectory prediction model will benefit this progress. According to the continuous beam theory, a mechanical model of push-...

In this paper, a planar active phased array antenna demonstration with linear polarization (LP) at Ka Band (28-30 GHz) is presented. The proof of concept carried out to evaluate the possible problems that may arise, analyze calibration stages and assess viability integration an system Multi-Channel Beamforming Module (MCBM). To fulfill task $8\times 8$ -element arranged in column subarrays $1\t...
