ASSURANCE OF ACCURACY IN ASSEMBLING A PLANETARY ECCENTRIC REDUCTION GEAR WITH MODIFIED TEETH OF A SATELLITE GEAR BY USING METHODS OF CALCULATION OF LINEAR DIMENSION CHAINS

To assure the safety of the power bogies for train, it is important to perform the durability analysis of reduction gear considering a variation of velocity and traction motor capability. In this study, two types of applied load histories were constructed from driving histories considering the tractive effort and the train running curves by using dynamic analysis software (MSC.ADAMS). Moreover, this study was performed by evaluating fatigue damage of the reduction gears for rolling stock using durability analysis software (MSC.FATIGUE). The finite element model for evaluating the carburizing effect on the gear surface was used for predicting the fatigue life of the gears. The results showed that the fatigue life of the reduction gear would decrease with an increasing numbers of stops at station.

Background and objectives: Identification, an aspect of forensic anthropology, is the recognition of an individual based on the physical characteristics unique to the individual. Among the four main attributes i.e. gender, age, stature and ethnic or racial background of an individual’s biological identity, sex determination is usually the first step in the human identification process. Teeth can be used as a means of sex determination as teeth are resistant to post-mortem degradation and survive deliberate, accidental or natural change. This study was carried out with an objective to determine the sexual dimorphism of maxillary and mandibular canine by linear tooth diameter for permanent dentition in Moradabad population. Material and Methods: A total number of 40 subjects (20 Males and 20 Females) were included in this study. After obtaining an informed written consent, alginate impression was taken with help of perforated impression trays and study models were prepared with type IV dental stone. Linear (MD, BL, Crown Height) were taken with digital vernier caliper. Results: It was observed that males’ shows more mean linear crown diameter as compared to females. Also, the mesiodistal and buccolingual measurement shows statistically significant difference for all canines, being higher for males than females. Conclusion: The present study has expressed sexual dimorphism of permanent canine using Student’s test and indicate that linear dimension of maxillary canine can be used for sexual diamorphism with accuracy along with other accepted procedure for sex determination.

Topological Linear

Suppose that E is a compact subset of a topological linear space ℒ. Then the convex kernel K, of E, is such that a point k belongs to K if every point of E can be seen, via E, from k. Valentine (l) has asked for conditions on E which ensure that the convex kernel K, of E, consists of exactly one point, and in this note we give such a condition. If A, B, C are three subsets of E, we use (A, B, C) to denote the set of those points of E, which can be seen, via E, from a triad of points a, b, c, with a ∈ A, b ∈ B, c ∈ C. We shall say that E has the property if, whenever A is a line segment and B, C are points of E which are not collinear with any point of A, the set (A, B, C) has linear dimension of at most one, and degenerates to a single point whenever A is a point.

Chemical analysis of 12 soil profiles on granite showed that all except two had lost phosphate by leaching. The loss of phosphorus from each profile is calculated in grams per sq centimetre of profile surface, and as a percentage of the amount originally present. Three methods of calculation are used, each being based on one of the following assumptions as to the changes which take place on rock weathering: that there is (a) no change in weight, (b) no change in volume, (c) no loss of zirconium. The three methods are generally consistent in showing which soils are the most leached and which are the least leached. The estimated loss of phosphorus from each profile depends on which assumption is made. There is no simple correlation between the loss of phosphorus and the present rainfall. Reasons which are suggested are that the soils differ in age, in level of organic matter, and possibly in the rates of weathering of the parent rocks. Up to two-thirds of the phosphorus retained in the soil is chemically bound by the free oxides of iron and aluminium.
