The Implementation of Group Investigation Learning Model Through Domino Mathematics Media on the Rank Number and Root Form Materials

This study aims to find out the results of students' learning through the implementation of a group investigation learning model through mathematical domino media better than the implementation of a conventional learning model on the rank number and root form materials. The research was a quasi-experiment with the design of a randomized control group pretest-posttest. The population of this research is the entire class IX SMP Negeri 1 Lhokseumawe consisting of 9 classes. The research sample was determined by a randomized technique that made 2 classes namely experiment class (IXA) and control class (IXB). The results of the student posttest data test show that the data is distributed normally and homogeneously, so it can be analyzed with one-side t-test statistics at a significant α= 0.05. Based on the results of data processing against the posttest students obtained sig scores. (2-tailed) posttest data is 0.001 which means less than α= 0.05, this means H0 is rejected, so it can be concluded that the learning results of students taught by the group investigation learning model through domino mathematics media are better than conventional learning models on the rank number and root form materials in grade IX of SMP Negeri 1 Lhokseumawe.

Jitter Remains Stable Throughout a Single Fiber EMG Session in Healthy and My-Asthenic Muscles

Fatigability is the hallmark of myasthenia gravis (MG). It is not clear, however, whether there is an analogous increase in jitter during the course of a single fiber electromyography (SFEMG) session. The individual jitter values of all potentials of 76 normal and 44 myasthenic orbicularis oculi muscles were assigned a rank number according to their temporal order in which they were collected and linear regression was performed to determine if the slope of the regression line was significantly different from zero. Control and MG subjects displayed rather flat linear regression lines with non-significant positive or negative slopes. Accordingly, ROC analysis yielded areas under the curve near 0.5. We conclude that there is no systematic jitter increase during the collection of 20 potential pairs in a typical SFEMG session.

The National Culture, Best Countries Rank Number, Corruption Performance Index, and Governance. A Study in 8 Countries.

This study implements correlation analysis to explore the relationships between the national culture; best countries rank number, Corruption Performance Index (CPI) and governance in 8 countries in the Europe region (Croatia, France, Hungary, and Italy) and Asia region (Indonesia, Malaysia, Philippine, and Singapore). The national culture based on six dimensions of Hofstede et al. The best countries rank number based on usnews.com. The CPI based on transparency.org. The Governance based on The World Bank Worldwide Governance Indicators, in six expressions. The two highest of culture indicators is Malaysia (Power distance and Indulgence). The two most top indicators of culture are Hungary (Individualism and Masculinity), while the highest uncertainty avoidance is France, and the highest score of long term orientation is Singapore. The highest CPI Score is Singapore (84 out of 100 ratings), and the highest number of best countries is France (9 out of 80 countries). Six indicators of Culture correlate with governance indicators. CPI correlates with best countries rank number and five governance indicators. Country Rank correlates with six governance indicators. The results show that not all of the variables correlate with other variables, but governance correlates with all the three variables. These suggest that the improvement of national culture, the higher the rank number of the best countries and the higher the CPI will lead to being better governance.

A Probabilistic Hyperspectral Imagery Restoration Method

Hyperspectral image (HSI) restoration is an important task of hyperspectral imagery processing, which aims to improve the performance of the subsequent HSI interpretation and applications. Considering HSI is always influenced by multiple factors—such as Gaussian noise, stripes, dead pixels, etc.—we propose an HSI-oriented probabilistic low-rank restoration method to address this problem. Specifically, we treat the expected clean HSI as a low-rank matrix. We assume the distribution of complex noise obeys a mixture of Gaussian distributions. Then, the HSI restoration problem is casted into solving the clean HSI from its counterpart with complex noise. In addition, considering the rank number need to be assigned manually for existing low-rank based HSI restoration method, we propose to automatically determine the rank number of the low-rank matrix by taking advantage of hyperspectral unmixing. Experimental results demonstrate HSI image can be well restored with the proposed method.

Innovation Management: The Past, Present and Future of the Market

The paper presents aspects of innovation management, important issues based on literature and studies by Boston Consulting Group (USA). The case study lays on the survey made by BCG on 1500 subjects all over the world from all the industry sectors. The paper studies the importance of innovation management and makes predictions for research and development expenditure for Top4, Apple, Google, Tesla Motors and Microsoft, without taking into account rank number 5, Samsung, because the official income statement was in Korean Won.

The Evolution of theManṣabSystem Under Akbar Until 1596–7

The organization of the nobility of the Indian Mughal Empire in numerical grades (manṣabs) is now generally recognized as one of the basic elements of its administrative and military structure. Equally general, perhaps, has been a recognition of themanṣabsystem's many complexities. However, by combining the information in Abu 'l-Faẓl'sĀ'īn-i Akbarīwith a number of 17th-century texts and documents, it has been possible to construct a tolerable picture of the working of themanṣabsystem during the 17th century. In many respects, the basic features were first delineated by Moreland and Abdul Aziz; but their views have been greatly refined, and often substantially revised, by M. Athar Ali and Irfan Habib. It is now accepted as beyond argument that by Akbar's death (1605),manṣabwas explained in two numerical representations: the first,zāt, determined the holder's personal pay (ṭalab-i khāṣa) and status in the hierarchy; the second (sawār) indicated the number of horsemen to be maintained by the holder and set the amount sanctioned to cover their pay (ṭalab-i tābīnān). In each case, the rank-number was converted into monetary claims and military obligation by means of the schedules (dastūr al-'amals) in force at the time. The system undoubtedly gave to the Mughal nobility and military machine a high degree of uniformity and regularity in its functioning, which is likely to have contributed greatly to the stability and strength of the Empire.

On the Rank Numbers of an Arc

The kth rank number, rankkB, of a differentiable arc B in real projective n-space is the least upper bound of the number of osculating k-spaces of B which meet an (n – k – l)-flat, k = 0, 1, …, n – 1. The number rank0B is called the order of B; cf. 1.1-1.3. It has been conjectured by Peter Scherk that(0.1)equality holding if and only if B has the order n; cf. [2, p. 396]. In this paper we prove the following results.THEOREM 1. If B is a differentiable elementary arc, then (0.1) holds for k = 0, 1, …, n – 1.THEOREM 2. If B is a differentiable elementary arc and order B > n, then rankkB > (k + 1) (n – k) for k = 1, …, n – 2.By a theorem of Park [3, p. 38], every differentiable arc contains a subarc of order n. This eliminates the assumption that B is elementary from Theorem 1. We do not know whether it can be dropped from Theorem 2.
