Meal Delivery

At present, the demand for on-demand meal delivery is increasing, and the main delivery pattern is rider delivery. However, rider delivery has certain problems in terms of timeliness and security. Due to its advantages of being fast, convenient, and safe, drone delivery can, to a certain extent, solve the problems of rider delivery. However, can drone delivery completely replace rider delivery? The paper mainly uses the prospect theory to discuss the conditions under which drone delivery is superior to rider delivery based on four factors: delivery distance, degree of rider delay, pickup time, and consumer attitudes towards drone delivery. Based on the research, it was found that when the delivery distance is more than 7 kilometres, the pickup time is within 2 minutes, or when consumers accept drone delivery, drone delivery is better than rider delivery. When the rider’s delay caused the delivery time to increase by more than 20%, the advantages of drone delivery began to stand out. Moreover, research has proven that drone delivery will help expand the scope of instant delivery, and the rational layout of drone airports and strengthening of consumer awareness and friendliness towards drone delivery will also help promote the development of drone delivery.

Utility Scores

Objectives: Prospect theory (PT) hypothesizes that people judge states relative to a reference point, usually assumed to be their current health. States better than the reference point are valued on a concave portion of the utility function; worse states are valued on a convex portion. Using prospectively collected utility scores, the objective is to test empirically implications of PT.Methods: Osteoarthritis (OA) patients undergoing total hip arthroplasty periodically provided standard gamble scores for three OA hypothetical states describing mild, moderate, and severe OA as well as their subjectively defined current state (SDCS). Our hypothesis was that most patients improved between the pre- and postsurgery assessments. According to PT, scores for hypothetical states previously > SDCS but now < SDCS should be lower at the postsurgery assessment.Results: Fourteen patients met the criteria for testing the hypothesis. Predictions were confirmed for 0 patients; there was no change or mixed results for 6 patients (42.9 percent); and scores moved in the direction opposite to that predicted by PT for 8 patients (57.1 percent).Conclusions: In general, the direction and magnitude of the changes in hypothetical-state scores do not conform to the predictions of PT.

FPGAs are suitable to speed up gene regulatory network (GRN) algorithms with high throughput and energy efficiency. In addition, virtualizing FPGA using hardware generators and cloud resources increases the computing ability to achieve on-demand accelerations across multiple users. Recently, Amazon AWS provides high-performance Cloud's FPGAs. This work proposes an open source accelerator generator for Boolean gene regulatory networks. The generator automatically creates all hardware and software pieces from a high-level GRN description. We evaluate the accelerator performance and cost for CPU, GPU, and Cloud FPGA implementations by considering six GRN models proposed in the literature. As a result, the FPGA accelerator is at least 12x faster than the best GPU accelerator. Furthermore, the FPGA reaches the best performance per dollar in cloud services, at least 5x better than the best GPU accelerator.

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).
