Results of comprehensive surveys (1980 and 1988) were compared relative to physical education for handicapped students. A direct, self-report methodology was used. Statewide (Ohio) samples of 241 (1980) and 242 (1988) physical education teachers participated. Data indicated that the status of physical education for handicapped students had remained the same. By 1988, only 14% of the teachers had contributed to a multidisciplinary staff for developing IEPs. Teachers’ lack of knowledge of PL 94-142 was revealed in both years, and interest in teaching handicapped students was no better than “neutral/mixed” (1988). A majority of teachers in 1980 and 1988 indicated a general need for assistance in motor behavior assessments. By 1988 a majority of teachers (51%) had not received encouragement/support from their administration. In both years, over 75% believed that handicapped students are excluded from participation in physical education due to “nature of handicap” and “functional ability.” Overall, results in 1980 were reaffirmed in 1988. Teachers lacked the ability to provide appropriate physical education for handicapped students.

Power sports have always been very popular among servicemen. This is especially evident in recent times, when such power sports, as armsport, crossfit, kettlebell lifting, powerlifting have received some development. The article presents a comparative analysis of the power capabilities of cadets who specialize in various power sports. The study involved male cadets of the 4th year of various faculties (n=53) of the Military Academy (Odessa), who in the process of training were engaged in power sports: armsport (n=12), crossfit (n=16), kettlebell lifting (n=15), powerlifting (n = 10). In addition, the results of cadets-athletes were compared with the results of cadets of the faculty of training specialists of airborne assault troops and military intelligence and special purpose, who did not attend sports sections of the academy (n=60). Analysis of the power of the cadets was carried out on the following exercises: pull-up, lifting by coup, lifting by strength on the crossbar, 24 kg kettlebell snatch, push-up on the parallel bars, push-up. The conducted researches testified to the high level of development of power qualities of cadets of all sections of academy in power sports. There was no significant difference between the results of cadets of different power sports in most exercises. It is established that the power capabilities of cadets who are engaged in various power sports are significantly better than those of cadets who are not engaged in sports. This suggests that any of the studied power sports can be an effective means of developing and improving the power opportunities of future officers of the Armed Forces of Ukraine

Detection of outliers or anomalies is one of the vital issues in pattern-driven data mining. Outlier detection detects the inconsistent behavior of individual objects. It is an important sector in the data mining field with several different applications such as detecting credit card fraud, hacking discovery and discovering criminal activities. It is necessary to develop tools used to uncover the critical information established in the extensive data. This paper investigated a novel method for detecting cluster outliers in a multidimensional dataset, capable of identifying the clusters and outliers for datasets containing noise. The proposed method can detect the groups and outliers left by the clustering process, like instant irregular sets of clusters (C) and outliers (O), to boost the results. The results obtained after applying the algorithm to the dataset improved in terms of several parameters. For the comparative analysis, the accurate average value and the recall value parameters are computed. The accurate average value is 74.05% of the existing COID algorithm, and our proposed algorithm has 77.21%. The average recall value is 81.19% and 89.51% of the existing and proposed algorithm, which shows that the proposed work efficiency is better than the existing COID algorithm.

Montesquieu, one of the greatest figures of the Enlightenment, was famous in his own century both in France and in foreign lands, from Russia to the American colonies. Later generations of French philosophes took for granted his concern to reform the criminal laws, to replace the Inquisition with a reign of tolerance, and to repudiate the vicious conquests of the Spaniards in the Americas. They also accepted his finding that Protestant, commercial, and constitutionalist England and Holland represented all the best possibilities of Europe; whereas Catholic, economically backward, and politically absolutist Portugal and Spain represented the worst of the Western world and constituted a warning to the French. Although the findings and specific reforms proposed by Montesquieu were repeated by many another figure of the French Enlightenment, his work in certain respects remained unique in the circles of the most advanced thinkers. In his efforts to think systematically about politics and to do so by employing the comparative method, he stands virtually alone in his age. Other thinkers sharing his commitments resorted to the universalizing language of natural rights when they ventured into the realm of political philosophy. Or, like Voltaire, they tied their thoughts about politics to a succession of specific issues, each essay bearing so indelibly the imprint of specific time and place that there was no room for theory in their writings. Finally, as is true of Diderot or D’Alembert, many of the philosophes were slow to recognize what Montesquieu knew from the outset, that if Enlightenment does not extend to politics it is futile. Steeped in Montaigne’s scepticism, Montesquieu found that in the absence of absolutes there were good reasons to appreciate the ‘more than/less than’ and ‘better than/worse than’ judgments of comparative analysis. In his notebooks he commented that the flaw of most philosophers had been to ignore that the terms beautiful, good, noble, grand, and perfect are ‘relative to the beings who use them’. Only one absolute existed for Montesquieu and that was the evil of despotism, which must be avoided at all costs. Montesquieu wrote three great works, each teaching lessons about despotism and freedom,The Persian Letters (1721), the Considerations of the Grandeur of the Romans and the Cause of Their Decline (1734), and The Spirit of the Laws (1748).

Two common types of animal-vehicle collision data (reported animal-vehicle collision (AVC) data and carcass removal data) are usually recorded by transportation management agencies. Previous studies have found that these two datasets often demonstrate different characteristics. To accurately identify the higher-risk animal-vehicle collision sites, this study compared the differences in hotspot identification and the effect of explanation variables between carcass removal and reported AVCs. To complete the objective, both the Negative Binomial (NB) model and the generalized Negative Binomial (GNB) are applied in calculating the Empirical Bayesian (EB) estimates using the animal collision data collected on ten highways in Washington State. The important findings can be summarized as follows. (1) The explanatory variables have different effects on the occurrence of carcass removal data and reported AVC data. (2) The ranking results from EB estimates when using carcass removal data and reported AVC data differ significantly. (3) The results of hotspot identification are different between carcass removal data and reported AVC data. However, the ranking results of GNB models are better than those of NB models in terms of consistency. Thus, transportation management agencies should be cautious when using either carcass removal data or reported AVC data to identify hotspots.

Background. The aim of the present article was to report our experience with the treatment ofpatients with hallux valgus and to perform comparative analysis of the results of the newly proposed and standard methods for its surgical correction. Methods. The data on 70patients (101 feet) with hallux valgus that were operated on between 2011 and 2015 in St. Petersburg Hospital No 2 using the new and standard methods were analysed. The functional assessment (AOFAS score) and X-ray examination were performed preoperatively, 3 and 12 months after the procedure. Comparative analysis between patients undergoing surgical correction by the new and standard methods has been undertaken. Results. We did not find any significant difference between the two groups in mean AOFAS score 12 months after surgery. Nevertheless, the function score of the patients treated by the newly proposed method (79.4±6.5 in 3 months) was significantly better than in those given the standard treatment (72.2±7.6 in 3 months). Mean intermetatarsal angle 12 months after surgery by standard and new methods was 9,7±0,7° and 8,6±0,7° (p<0.05), mean metatarsophalangeal angle 13,6±0,9° and 13,0±1,1° (p<0,05) respectively. Conclusion. According to the data obtained, the original method of hallux valgus surgical correction allows to improve its functional and x-ray results.

Data Mining is an emerging research field in the analysis of agricultural data. In fact the most important problem in extracting knowledge from the agriculture data is the missing values of the attributes in the selected data set. If such deficiencies are there in the selected data set then it needs to be cleaned during preprocessing of the data in order to obtain a functional data. The main objective of this paper is to analyse the effectiveness of the various imputation methods in producing a complete data set that can be more useful for applying data mining techniques and presented a comparative analysis of the imputation methods for handling missing values. The pest data set of rice crop collected throughout Maharashtra state under Crop Pest Surveillance and Advisory Project (CROPSAP) during 2009-2013 was used for analysis. The different methodologies like Deleting of rows, Mean & Median, Linear regression and Predictive Mean Matching were analysed for Imputation of Missing values. The comparative analysis shows that Predictive Mean Matching Methodology was better than other methods and effective for imputation of missing values in large data set.


In the age of emerging technologies, the amount of data is increasing very rapidly. Due to massive increase of data the level of computations are increasing. Computer executes instructions sequentially. But the time has now changed and innovation has been advanced. We are currently managing gigantic data centers that perform billions of executions on consistent schedule. Truth be- hold, if we dive deep into the processor engineering and mechanism, even a successive machine works parallel. Parallel computing is growing faster as a substitute of distributing computing. The performance to functionality ratio of parallel systems is high. Also, the I/O usage of parallel systems is lower because of ability to perform all operations simultaneously. On the other hand, the performance to functionality ratio of distributed systems is low. The I/O usage of distributed systems is higher because of incapability to perform all operations simultaneously. In this paper, an overview of distributed and parallel computing is described. The basic concept of these two computing is discussed. In addition to this, pros and cons of distributed and parallel computing models are described. Through many aspects, we can conclude that parallel systems are better than distributed systems.

OFDM is a multiplexing technique that is used to divide a frequency spectrum into sub-carriers that are orthogonal to each other. They are capable to carry high rate data transmission. The orthogonality is maintained by keeping one sub carrier, null on the centre of other sub carriers. Sub-carriers have cyclic prefix which is placed in between them and the bandwidth wastage due to guard band is reduced up to 50%. Spectral efficiency is of OFDM is far better than other frequency modulation techniques due to othrognality. Additionally, CP design helps in better diversity gain. The data is dispensed as sub-streams among sub carriers and each of the sub carrier is modulated as per the coding (PSK, BPSK, QAM). Thus rather modulating whole data stream over a single frequency, sub carriers are allocated portions of data that ensure large amount of data processing. To ensure orthogonality, serial data is converted into smaller parallel streams and are fed to IFFT module, after which P/S conversion is performed and CP is inserted between the sub-carriers. The reverse of these steps happens in the receiving module. Important aspects of OFDM systems are, Synchronization, Pilot allocation,the Channel State Information or Channel estimation etc. However this paper takes up sub-carrier modulation techniques in OFDM systems and puts a comparative analysis of them.
