Noise and Performances Analysis of Commerical Aircrafts using Artificial Neural Networks
Commerical aircrafts are very important part for airway travelling. In spite of high technology on aircrafts, there is still fatality accidents in the world. Because of this reason, it is very important criteria to analyse noises of main elements of the air-craft systems. In tis study, an aircraft’s main disturbances are analysed with proposed neural networks. Firstly, the noises of the jet, turbine and fan were measured from the aircraft. Secondly, the measured parameter values were predicted the proposed neural networks. The results of the proposed neuarl approaches were shown that this type of neural predictors will be employed to predict aircrafts unpredicted disturbances in real time applications
Performance Analysis of An Experimental Micro Flexible Manufacturing System (FMS)
Due to advanced technology, it is very important the performance of FMS for sensivity, production quality, repeatability and energy consumptions. Flexible manufacturing systems (FMSs) are the most automated and technologically sophisticated of the machine cell types used to implement cellular manufacturing. An FMS usually has multiple automated stations and is capable of variable routings among stations, while its flexibility allows it to operate as a mixed model system. The FMS concept integrates many of the advanced technologies that we met in previous units, including flexible automation, CNC machines, distributed computer control, and automated material handling and storage.
In this experimental investigation, vibration and accelerations analysis of an experimental FMS with 5 degrees of freedom robot manipulator are presented. Firstly, experimental measurement of accelerations and vibrations are trained with a vibration measurement system and sensors. However, the process of production of part is a cycle of exact production time
An algorithm of avoiding obstacles with intelligent objects
In this research a path planning which is the first step of motion planning in robotic applications, away from an obstacle in an environment where exist many obstacles is developed. Different from the algorithms in literature, a path away from an obstacle is planned without determining the configuration free space in a place that contains many different shaped obstacles with the help of intelligent objects that are created object oriented programming(OOP). With the help of this developed algorithm not only the probable paths but also finding the shortest path and correcting it with the help of intelligent objects are evaluated at the same time. This algorithm is so profound that it can form the basic principles of many original Works with the additional in future works
Design of Neural Predictor for Performance Analysis of Mountain Bicycles
In recent years, bicycle races, along with the crest of the high technology continues to increase. Because of this increased races, performance of bicycles, in both biological and mechanical terms, is extraordinarily important and efficient. In terms of the ratio of cargo weight a bicycle can carry to total weight, it is also a most efficient means of cargo transportation. In spite of advanced technology, there are still some problems on bicycles during working conditions and road roughness such as on the mountain from tire and mechanical parts. In this investigation, a extraordinary designed with fiber-carbon body and light bicycle is tested on mountain road conditionswith prescribed trajectory on the mountain for different elevation, speed, hearth rate, bike cadence and average temperature. The real time measured parameters are predicted with proposed two types of neural networks for approaching real time neural network predictors. The results of the proposed neural network have shown that neural predictor has superior performance to adopt the real time bicycle performance

INVESTIGATION OF PEOPLE'S MORAL ATTITUDE WHO CAME TO THE SPORTS CENTER
The purpose of the study is to examine moral attitude differences of the people who come to sports centers in terms of some variables. In this study, Moral Attitude Scale, which is developed by Prof. Dr. Mevlüt Kaya, is implemented to 190 people who are from different sports centers in Burdur city center. In statistical analysis (frequency analysis) of the obtained data from the individuals who regularly do exercise (150 people) and do not regularly exercise (40 people), independent t test and one way ANOVA analysis were used. It is observed that the individuals who came to sports center regularly have higher moral attitude scores compared to those who do not come regularly. As a result, it is observed that there is no statistical differentiation in moral attitude evaluations between the people who came to sports centers in terms of demographic variables such as age, gender, income status.

The effects of storage temperature and storage time on the somatic cell count of anatolian buffaloes
This research examined the effects of storage temperature and storage time on the somatic cell count (SCC) of milk from Anatolian buffaloes, which was measured with the DeLaval cell counter (DCC). Storage temperature and time are among the different factors that potentially affect the SCC of Anatolian buffalo milk. In this context, 20 milk samples were collected from Anatolian Buffaloes and analyzed. The milk samples were divided into two groups according to their measured level of SCC. These two groups were the low score (?3.16 cell/ml) group and the high score (>3.16 cell/ml) group. The mean logSCC values of the low score and the high score groups were determined as 2.27±0.045 and 4.06±0.019 cells/ml, respectively. In this research, the effects of storage temperature (4ºC, 21ºC) and storage time (fresh milk, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 and 24 h) on logSCC were determined to be statistically significant (P<0.01). Thus, increases in storage temperature and storage time were associated with an increase in the logSCC of the milk samples. © 2019, International Buffalo Information Center, Kasetsart University.

Peat Use in Horticulture
Peat is a spongy substance which is an effect of incomplete decomposition of plant residues in different stages of decomposition. Between the several organic matters which are used as substrate for horticultural plants cultivation in soilless conditions, peat is the unabandonable ingredient for mixtures for commercial production of plants. Peat is used in horticulture as a component of garden plant substrates, in agriculture for the production of garden soil and as an organic fertilizer, and in balneology as a material for baths and wraps. The use of peat for agriculture and horticulture is determined by the following quality parameters: the degree of decomposition, ash content, pH, the presence of carbonates, the density of the solid phase, bulk density, and porosity. As an organic material, the peat forms in the acidic, waterlogged, and sterile conditions of fens and bogs. The conditions seem like the development of mosses. The plants do not compose as they die. Instead of this, the organic matter is laid down and accumulates in a slow time as peat due to the oxygen deficiency in the bog. This makes peat a highly productive growing medium. In the present novel review, we discuss the peat use in horticulture
