Unmanned Aerial Vehicle become popular and very useful today. Unmanned Aerial Vehicle types have fixed wing UAV and rotary wing UAV. Among rotary wing UAV, helicopter type is chosen to implement the mathematical model for UAH. Since these helicopter mathematical model is very complex and inflexible, simple model “minimum-complexity helicopter simulation math model” (MCHSMM) is used to develop a non-linear mathematical model R-50 helicopter for this work. This modeling consists of three blocks: (1) Rigid body dynamics, (2) Force and torque dynamics, and (3) Flapping and thrust dynamics. Each of these are implemented in MATALB SIMULINK. There are four control inputs: ulat (lateral control input), ulong (longitudinal control input), ucol (collective control input) and uped (pedal control input). By alternating positive, negative, and zero to four control inputs, the resultant responses of positions, Euler angles, translatory velocities, angular velocities and flapping angles are simulated
Health service is conducted to obtain a better level of health of the society. A decent level of health would increase of productivity, quality of life, and human development index as well as reducing poverty. The objectives of the research are (1) to analyze the effects of health services for the poor people on the health status in Medan City and (2) to analyze the effect of health and human services on regional developments in Medan City. This is an explanatory research. Population is poor family living in Medan City having Askeskin or Jamkesnas card. A number of 876 samples were chosen proportionally from 21 sub- district of Medan City. The effect of health service of poor people on human and regional development was analyzed by linear regression test. The result showed that there was a significant effect of the level of health services on health of poor people. Also, there is a significant effect of the quality of health service on human development in the regional development pers
While considering the optimization in the geometry of the leaf spring, it can be said that the design of leaf spring is quiet thickness sensitive due to its relative dimensions & the loading direction. Hence stress analysis of a mono leaf spring is done by F.E.M. before and after changing the variation of its thickness along the length. The variation of thickness considered initially is linear. After careful study it was judged that if the thickness is varied parabolically along the length of the leaf spring, better results can be obtained. Hence the values of stress at different points along the length (average values at various cross sections) for both geometries are compared graphically. In short the stress variation along the length for both geometries is plotted on graph and comparison is visualized by overlapping of graphs. An Improvement in the distribution of stress along the length improves the utilization of material & thus mass of the leaf spring can be reduced.
In this paper a two dimensional non-linear map is taken, whose various dynamic behavior is analyzed. Some useful numerical algorithms to obtain fixed points and bifurcation values of period n 2 , n 0,1,2... . have been discussed. It has shown how the ratio of three successive period doubling bifurcation points ultimately converge to the Feigenbaum constant. This ascertains that the map follows the period doubling route to chaos. The parameter value where chaos starts is verified by lyapunov exponent. Further various fractal dimensions like Correlation dimension, Box-counting and Information dimension have been calculated to verify the geometry of the strange attractor.
Sensors in the equipment can detect when, and how often, operators are not only speeding, but also doing heavy braking, driving without lights at night, or other unsafe behaviors. These problems aren’t limited to pickups and on-road haulers: Think about ADTs navigating haul roads, where excessive braking can lead to unnecessary wear and subsequent diminished braking, or wheel loader, grader and backhoe operators that need to see—and be seen—while traversing large, spread-out job sites or long, linear highway jobs.
This paper proposes the artificial neural network based controller for speed control of a separately excited DC motor. The Artificial Neural Network controller allows controlling both type of systems i.e. linear and non-linear system by training the network. So it is a novel approach to study and a broad research area.
BACKGROUND: Stroke is an important cause of disability and death. Recently several studies have claimed that RDW is a good predictor of outcome in stroke. As RDW is a complete blood count (CBC) parameter that is routinely determined in clinical laboratories, these studies important implications in patient management in developing countries. The present study was taken up to find out if RDW can be used as an inexpensive biomarker for stroke. MATERIALS AND METHODS: A case-control study involving 52 test subjects and 54 matched controls was conducted. RDW values were determined in test and control groups, compared and statistically analysed. RESULTS & CONCLUSIONS: Significantly higher mean values for RDW (p <0.001) are observed in stroke patients compared to reference population. RDW values higher than 13.0 are associated with several fold increase in the risk of stroke (odds ratio 4.1; p value <0.006); but, the level of RDW does not show a linear relationship

Phototoxic and photoallergic reactions represent skin reactions to the sun, in the presence of photoactive chemicals applied on the skin or taken systemically. They have a highly polymorphic clinical presentation – photo contact urticaria, eczema on sun-exposed areas sometimes with erythema multiforme, exaggerated sunburn, linear phytophotodermatitis, pseudoporphyria, photoonycholysis, dyschromia, and lupus erythematosus. Also, skin cancers are increasingly associated with exposure to photoactive chemicals. There is a geographical and timely variation in the responsible agents, but they are mostly furocumarins from plants, UV filters in sunscreens and cosmetics, and drugs (NSAIDs, antimicrobials, phenothiazines, amiodarone, etc.) Three drugs like Chloramphenicol, Norflox, and Kucil(Fluorouracil) were tested for Phototoxic effect procured from local market and check the ph and absorption spectra and note and solubility of test drug was tried out through different solve
