Modern Automated System for Traffic Signals
This work has been designed to develop an a dynamic road signal based on an
emergency with density. The sync signal automatically switches to detecting traffic density at
the intersection. Traffic congestion is a serious problem in many large cities around the world
and has become a nightmare for travelers in these cities. The conventional traffic light system
is based on the concept of fixed time assigned to each side of the join that cannot be varied by
varying traffic density. The tie times assigned are fixed. But in an emergency, emergency
timings change according to the distance and depth of the traffic. At the time the emergency
vehicle is read by the receiver it will execute the management of the traffic light. These
projects are infrared proximity sensors in the sightline configuration through the load to
detect the traffic light density. The vehicle density is measured in several sectors based on
the times assigned as a result. Every crossing of the emergency vehicle logs the data's to
the cloud. This log signal would help with the destination acknowledgment. This
synchronization will greatly reduce traffic jam
Relapse rates following stage surgery in the treatment of recalcitrant talipes equinovarus: 9-16 year outcome study
Purpose We aimed to identify the long-term rate of relapse of deformity in a cohort of children with talipes equinovarus and to correlate it with pre-operative grading.
Methods Between 1988 and 1995, 120 club feet in 86 patients were surgically treated. A review at an average follow-up of 11.5 years (range 9–16 years) was performed. Of 59 of the children, 69 feet were assessed clinically and data for the remaining 20 children (30 feet) were obtained from the records. The patients were assessed using the method of Bensahel and Dimeglio but radiological analysis was omitted. Functional and morphological evaluation was recorded.
Results Initial grades were grade 2 in 26 feet (26%), grade 3 in 48 feet (49%) and grade 4 in 25 feet (25%). Relapse occurred in one case in grade 2 (3.8%), 13 feet in grade 3 (27%) and in 19 in grade 4 (76%). Since an initial review in 1997, a further 12.5% of grade 3 and 25% of grade 4 feet have relapsed. Overall function did not correlate with severity of deformity.
Conclusion Relapse continues to occur after surgery during the first decade. There is a high rate of relapse (76%) in grade 4 feet
Prenatal ultrasound: detection and diagnosis of limb abnormalities
Summary: Many cases of congenital limb abnormalities referred for orthopaedic treatment are not diagnosed prenatally, despite routine ultrasound scanning. The authors aimed to study the detection rate and diagnostic accuracy of prenatal scans. Data concerning two groups of patients were collected. First, the authors followed-up 26,203 babies that had been scanned prenatally. Sixty had limb abnormalities; 15 of the abnormalities were detected prenatally (sensitivity 25%, 95% confidence interval 14%-36%). Second, the authors studied 67 cases from the Wessex Antenatally Detected Anomalies Register that had been identified prenatally. The diagnosis was confirmed postnatally in 56 cases (positive predictive value 84%, 95% confidence interval 75%-93%)
