A BASIC STUDY ON THE RELATIONSHIP BETWEEN THE DRIVING SPEED AND THE MEASUREMENT PRECISION OF MMS

Finite element analysis is undertaken to identify the extent of loading deformation of instrumented indentation equipment frame which is a main part in High-precision instrumented indentation tester developed and realized by our group. The working load enacted in the model is varied from 10N to 100N, and the increment load is 10N. By plotting and fitting data of inclination angle and working load, the relationship between frame inclination angle and working load is established. The function of this relationship is θ=0.000024*F. When the working load is up to the upper bound 100N, the inclination angle of frame reaches the maximum value 0.00241°.Load analysis of push rod shows that the percent error between measured load values and real indentation load values caused by maximum inclination angle is in 10-8order. The conclusion is thus derived that frame inclination has nearly no effects on load measurement precision. The research in this paper confirms that the design of frame belonging to High-precision instrumented indentation tester is appropriate.

The Relationship

Productive lifes short by health problems cause inhaling dirty air generate from motor vehicle exhaust emissions. Transport activities generate air pollutants that lead to the onset of disease Acute Respiratory Infection (ARI). The purpose of this study is to analyze the relationship between driving behavior and mileage with ARI at Airlangga University students. This research was an observational analytic study and case control design. The sample size in this study was 44 people for each group of cases and controls with systematic random sampling technique. To determine the relationship and odd ratio, the study used statistical Chi Square test. The results showed that there was a relationship between driving behavior consists of the used of PPE (p = 0.008), speed drive (p = 0.001), and the distance (p = 0.001) with ARI. Respondents who never wore PPE might increase that risk of acute respiratory infection 2.6 times compared with respondents who always wear PPE. Driving speed of <60 km/hours had 5.4 times the risk of developing ARI than respondents with speed >60 km/hours. Mileage ≥5 km had 5.156 times the risk of acute respiratory infection compared with respondents mileage <5km. It was concluded that driving behavior and mileage associated with ARI. It is recommended that officers PLK Airlangga University type C provide brochures, free masks, and held a car free day to students with the aim of reducing the incidence of ARI.

Car Driving

The purpose of this research is develop assistive robots and apparatuses. There is a pressing need to develop new systems that assist and act for car driving and wheelchairs for the elderly as the population ages. In developing systems, it is thought to be important to examine behaviors spatial recognition. Experiments have therefore been performed to examine human spatial perceptions, especially left- and rightside visual recognition, while cars being driven using near-infrared spectroscopy (NIRS). Previous research found significant differences in the dorsolateral prefrontal cortex in the left cranial hemisphere during virtual driving and actual driving tasks. This paper discusses the measurement of brain activity during car driving. A detailed analysis was performed by segmentalizing brain activity during driving based on the motion of subjects, and we report on the relationship between brain activity and movement perception during driving.

The Relationship

The oxygen transfer efficiency of spiral flow aeration is affected by many factors, for example, the shape of aeration tank, the type of diffuser, the air flow rate and so on. The authors tried to determine the relationship between these factors and the efficiency of aeration. We found these factors were restricted by some independent variables, so we analyzed quantitatively the relationship between these variables and the efficiency of aeration based on data from the full scale experiments on spiral flow aeration using porous ceramic diffusers. Regression equations show that the efficiency of the spiral flow aeration would be higher with a reduction of the air feed rate per tank volume and an increase of the total bubbling area of the diffusers. Other variables would not so greatly affect efficiency.
