A K-Nearest Neighbors ’ based on Clustering for High Performances and High Volumes of the Data

A new classification method is presented which uses clustering techniques to augment the performance of K-Nearest Neighbour algorithm. This new method is called Nearest Cluster approach, [NC]. In this algorithm the neighbour samples are automatically determined using clustering techniques. After partitioning the train set, the labels of cluster centers are determined. For specifying the class label of a new test sample, the class label of the nearest cluster prototype is used. Computationally, the NC method of KNN is faster than the k-means with 2 times. Also the clustering techniques leads to find the best number of neighbours based on the nature of feature space. The proposed method is evaluated standard sales dataset. Experimental results show the excellent improvement both in accuracy and the time complexity in comparison with the KNN method. Many clustering algorithms have been developed to address the problem of very large data size as well as for high dimensional data. This algorithm have their own disadvantages but they are often impractical when the data is large in both aspects. The proposed system uses the KNN algorithm based clustering so the KNN queries can be evaluated with minimum
Educational preparation and training of the family caregivers of elderly patients with stroke in the pre-discharge period : A proposed innovation

Introduction: Stroke causes disability that affects the life of patients, their relatives and the society in general. Global healthcare policies, suggest the sooner possible discharge of stroke patients from hospitals, but the transition to home is a stressful experience for family caregivers who are suddenly faced with the responsibility of homecare provision. Sufficient international evidence suggest that a pre-discharge educational program for preparing family caregivers could lead to better care, less complications and better quality of life, but Cyprus still do not provide such a program. Objectives: To challenge the current healthcare practices regarding the care of elderly patients with stroke and to propose an innovative training program that will be provided by the nurses during the pre-discharge period to family caregivers. Methodology: The proposed innovation is discussed around an overview of the international literature regarding the family caregivers' education in discharge planning and the Lewin's change theory, since the development and implementation of the innovation as a whole is based on this theory. Results: International literature highlights that family caregivers have a diversity of responsibilities at home but also unmet training needs. If these needs are not met, they may cause burden to caregivers, thus impeding their capacity to provide safe homecare to patients. Considering the significance of post-discharge homecare to the elderly patients with stroke, a proposed training program was designed for family caregivers, in an effort to motivate nurses in Cyprus to provide this preparation. Conclusions: An attempt should be made as for the proposed innovation to be included in the future planning of the care of stroke patients as part of the improvement reforms that are being pursued with the new national health system of Cyprus. Additionally, it is suggested that the Ministry of Health should create discharge services of elderly stroke patients in each hospital with the creation of a Discharge Coordinator role, who could coordinate the proposed innovation, while he/she could also inform staff on how to provide the training program to family caregivers.
Positive Disability Identity Predicts Sense of Belonging in Emerging Adults With a Disability

Given the importance of identity development and belonging for emerging adults, it is critical to examine how positive disability identity, one’s affirmative sense of identity as a person with a disability, relates to sense of belonging and need to belong in young adults with disabilities. Data were collected from a multi-institution collaboration across 32 sites. Participants with a disability (N = 502) completed online, self-report measures of need to belong, sense of belonging, social support, and positive disability identity. As expected, those who perceived greater social support were more likely to report a sense of belonging (r ranged from .36 to .55, p < .05) and positive disability identity (r ranged from .18 to .41, p < .05). Positive disability identity was more strongly related to sense of belonging in those who self-identify with a disability (z = 4.16, p < .001, Cohen’s q = .40). Also as hypothesized, positive disability identity predicted sense of belonging, even after controlling for the effects of social support and need to belong, in both those who identified with a disability (R2Δ = .12, Cohens f 2 = .14) and those who did not self-identify (R 2Δ = .02, Cohens f 2 = .02). These findings suggest that, although social support and a low need to belong were associated with a strong sense of belonging, developing a positive disability identity is also important in predicting a sense of belonging in emerging adults with disabilities.

Remote Upconversion of Radio Over Fiber by Band-Pass Filtering of Ultra-Short Pulse

A novel remote frequency upconversion of a radio-over-fiber (RoF) signal is proposed and demonstrated. The traditional RoF signal at transmitter is replaced with frequency chirped optical pulse modulated by base-band data. During fiber transmission, the optical pulse evolves into an ultra-short pulse under the effect of fiber dispersion. The upconversion is completed at the remote antenna unit (RAU) by just selecting out the target signal spectrum, which is shifted to the wanted high order harmonics with a band-pass filter. Thereby, the RoF system is simplified by removing the mixer and high-frequency local oscillator at the central office, still keeping RAU as simple as possible. With this approach, a 2-Gbit/s data up-converted to 16 GHz is received with a BER below 10-9 and spectrum efficiency of 1-bit/s/Hz after transmission of 45-km SMF and 7-m air without optical in-line, pre-amplificiation, dispersion compensation, and optical filtering.
A Trustworthiness-based QoS routing protocol for wireless ad hoc networks

Due to the fact that the wireless links in an ad hoc network are susceptible to attacks and the nodal mobility renders the network to have a highly dynamic topology, it becomes critical to detect major attacks against the routing protocols of such networks and also provide some extent of QoS to the network traffic. In this paper, we present a new secure routing protocol (SRP) with quality of service (QoS) support, called trustworthiness-based quality of service (TQOS) routing, which includes secure route discovery, secure route setup, and trustworthiness-based QoS routing metrics. The routing control messages are secured by using both public and shared keys, which can be generated on-demand and maintained dynamically. The message exchanging mechanism also provides a way to detect attacks against routing protocols, particularly the most difficult internal attacks. The routing metrics are obtained by combing the requirements on the trustworthiness of the nodes in the network and the QoS of the links along a route. The simulation results have demonstrated the effectiveness of the proposed secure QoS routing protocol in both security and performance.

N E ] 1 0 M ay 2 01 9 EENA : Efficient Evolution of Neural Architecture

Latest algorithms for automatic neural architecture search perform remarkable but basically directionless in search space and computational expensive in the training of every intermediate architecture. In this paper, we propose a method for efficient architecture search called EENA (Efficient Evolution of Neural Architecture) with mutation and crossover operations guided by the information have already been learned to speed up this process and consume less computational effort by reducing redundant searching and training. On CIFAR-10 classification, EENA using minimal computational resources (0.65 GPU−days) can design highly effective neural architecture which achieves 2.56% test error with 8.47M parameters. Furthermore, The best architecture discovered is also transferable for CIFAR-100.
2 Diverse Dialogic Pedagogies : Instrumental and Non-Instrumental Education

The concept of dialogue has become increasingly popular in diverse areas of social sciences. In the field of psychology, a dialogic framework has been introduced from studies of emotions (Garvey & Fogel, 2007) to the studies of memory (Fernyhough, 1996). Interest in the concept of dialogue can be found in many classical psychologists who have influenced modern sociocultural psychology: Vygotsky, Piaget, Mead, and so on. There has also been affinity between sociocultural psychology and dialogic framework (Wertsch, 1991). One of the major issues that dialogic approaches have faced in diverse social science fields is to conceptualize dialogue itself (e.g., O’Connor & Michaels, 2007). What is dialogue? What is a good dialogue? In this chapter, I want to discuss diverse approaches to dialogic framework in education as an independent sociocultural practice that sociocultural psychology investigates and consider how the field of dialogic pedagogy tries to address this issue of conceptualizing dialogue. I introduce non-instrumental dialogic pedagogies where dialogue is viewed as the medium, in which and through which meaning making and truth live. This view is contrasted with instrumental approaches to dialogic pedagogy that view dialogue as a tool for more effective education. Although being particular to the field of education, these conceptual and even political tensions in education may affect important debates in sociocultural psychology. 15.1 The Growth of Interest in Dialogic Approaches
Dynamics of Growth and Signaling along Linear and Surface Structures in Very Early Tumors

There exists evidence that in early stages tumors progress along linear, tubular, or irregular surface structures. This seems to be the case for atypical adenomatous hyperplasia (AAH), a precursor of adenocarcinoma of the lung. We previously published a simplified model, which showed that early structures had a potential towards spontaneous invasive growth following a latency phase. The transition was facilitated by diffusion of a growth factor and nonlinear cell cycle regulation in cancer cells. The mechanism is analogous to that in Turing pattern formation, although the patterns are irregular and unstable. We introduce more biologically justifiable signaling, in which only the free growth factor molecules diffuse. Flexible nonlinearities in the model accommodate several growth patterns of cells as well as internal versus external production of the growth factor. We show that the reaction-diffusion setup results in complicated spike-like solutions. We discuss these results in the light of published data on the AAH.
Experimental Aerodynamic Control of a Long-Span Suspension Bridge Section Using Leading- and Trailing-Edge Control Surfaces

We experimentally investigate the suppression of flutter in long-span suspension bridges. A rigid sectional model of a long-span suspension bridge is mounted in a wind tunnel on a suspension system. Control surfaces, which are used to suppress flutter, are movable flaps that are fitted to the bridge section's leading and trailing edges. The flaps are responsive to the deck's heave and pitch motions. In this paper, the aerodynamic force is modeled using a thin aerofoil theory, although other modeling techniques can be used. The controller has a second-order passive transfer function with inputs of a combination of the deck's pitch angle and heave position, and outputs of the flaps' angular positions. The control system design problem is solved as an H∞ optimization problem.
Why Employee Turnover? The influence of Chinese Management and Organizational Justice

Employee turnover is an important topic in organizational behavior research. Understanding how to address turnover in Chinese organizations is also a practice problem. The aim of this paper is to explore the impact of paternalistic leadership (authoritarianism, benevolence, and morality) on employee turnover and examine the moderating effect of organizational justice (distributive justice, interactional justice, and procedural justice). Data were collected from 207 supervisor and subordinate dyads of 51 stores in a Chinese food and beverage company. Paternalistic leadership and organizational justice were initially collected from subordinates. After six months, employee turnover was collected from supervisors. The results indicate that benevolent and moral leadership were both negatively related to employee turnover. Authoritarianism failed to predict employee turnover. Furthermore, the relationship between authoritarianism and employee turnover is moderated by distributive justice and procedural justice. Finally, the theoretical and practical implications of these findings are discussed.
Detecting and tracking human face and eye using an space-varying sensor and an active vision head

We have developed a system for detecting and tracking human face and eye in an unstructured environment. We adopt a biologically plausible retinally connected neural network architecture and integrate it with an active vision system. While the active vision system tracks the object moving in real time, the neural network detects the face and eye location from the video stream at a slower rate. The paper provides a systematic way of creating and selecting examples for training the network by exploring the link between theory and practice. Experimental results on a real sequence of images from a space-varying sensor depicts the performance of the system.
Investigation of moderator factors in e-business adoption: A quantitative meta-analysis of moderating effects on the drivers of intention and behavior

E-business technology is becoming one of the most important global markets where e-business solutions will have to adapt to new technologies. The main objective in this study was to synthesize existing knowledge in the field of e-business technology acceptance and to understand differences in Technology Acceptance Model (TAM) related causal effect sizes for different e-business contexts. A quantitative meta-analysis of existing empirical research about factors affecting e-business adoption was conducted using 89 published papers that provided empirical data about causal relationships. A moderator analysis was carried out to investigate the moderating effect of four factors: consumer type, device type, continent and respondent type. The results of the study showed a moderating effect for all four proposed factors in almost all TAM-related causal paths. The study also showed that TAM is the most common theory being applied in e-business adoption research.
Modified PID Controllers Design for Slow-Varying , Low-Damping Plants

ABSTRACT PID controllers have been widely used in industrial control systems for years. For quick design, We can use Zeigler-Nichols tuning method as the starting point. However, those plants with moderated oscillation in its step response will make the previous tuning approach in vain. J.C. Basilio and S.R. Matos [1] proposed a PID design approach to improve the tuning method recently. We study [2] in detail and make some other examples to verify their idea. Meanwhile, we propose a modified approach to [2] to cover some examples that [2] failed to apply to. We can handle well those systems with slow-varying, low-damping characteristics. Finally, we used Genetic Algorithms to modify the above solution.
On the test allocations for the best lower bound performance of partition testing

A partition testing strategy divides the program's input domain into subdomains according to a partitioning scheme, and selects test cases from each subdomain according to a test allocation scheme. Previous studies have shown that partition testing strategies can be very effective or very ineffective in detecting faults, depending on both the partitioning scheme and the test allocation scheme. Given a partitioning scheme, the maximin criterion chooses a test allocation scheme that will maximally improve the lower bound performance of the partition testing strategy. In an earlier work, we have proved that the Basic Maximin Algorithm can generate such a test allocation scheme. In this paper, we derive further properties of the Basic Maximin Algorithm and present the Complete Maximin Algorithm that generates all possible test allocation schemes that satisfy the maximin criterion.
Comparing synchronous and diachronic effects of sudden emergence of creative insights on the structure of the design process 059

This paper reports on a study of the emergence of creative insights in the architectural design process. Using detailed ethnographic observations of designers working on an architectural design task, and coding these using linkographs, we identify two poles of design creativity: incremental improvement and the sudden creative insight. We show how these can be identified in the structure of the linkograph, giving rise to the possibility of better understanding the conditions under which creativity and innovation take place. Linkography is directed in relation to the time of emergence of design utterances. It is characterised as a pivotal structure of a multi-level hierarchical network. A quantitative model is proposed to capture the structure of events and sudden changes occurring in the design process using syntactic measures of space syntax and urban graphs. Two situations are compared: synchronous designing using ‘directed linkography’ looking at the backlink relations and the completed state of the linkograph. Local, global measurements and directed j-graphs are correlated with design contents and descriptions for the concept development. Our interest lies in capturing events of drastic changes and investigating the transformation of the associated interim products. Such events are hypothesised, reflecting significant transformation in concept reasoning and the configuration of the linkograph. Through this model, we aim to answer the question: why would sudden insights divert the network to a different structure state?
Output Power Improvement by Impedance Matching Networks for a Class E Power Amplifier Driven Wireless Power Transfer Systems

Wireless power transfer working at several Megahertz has been continuously developed for charging small/medium-power devices during these years. A class E power amplifier can be used to drive the system with high efficiency. This paper uses the conventional class E power amplifier in a MHz system. A system-level analysis is carried out to show that the system efficiency can be maximized for different coupling coefficient. However, an output power is observed to decrease with the coupling coefficient. This drop is caused by the rectifier’s input reactance and the load sensitivity of the power amplifier. Then two different impedance matching networks are used to compensate this drop. In the experiment, the impedance matching networks can successfully enhance to output capability and provide a stable output power without tuning the input voltage. For the best case, the output power can be improved from 5 W to 10 W with an overall system efficiency about 80%.
Melatonin protects against isoproterenol‐induced myocardial injury in the rat: antioxidative mechanisms

Abstract: The present study was undertaken to explore the protective effect of melatonin against isoproterenol bitartrate (ISO)‐induced myocardial injury in rat. Treatment of rats with ISO increased the level of lipid peroxidation products and decreased the reduced glutathione levels in cardiac tissue indicating that this synthetic catecholamine induces oxidative damage following oxidative stress. Pretreatment of ISO‐injected rats with melatonin at a dose of 10 mg/kg body weight, i.p. prevented these changes. Additionally, melatonin also restored the activities and the levels of antioxidant enzymes which were found to be altered by ISO treatment. Treatment of rats with ISO resulted into an increased generation of hydroxyl radicals with melatonin pretreatment significantly reducing their production. Finally, treatment of rats with ISO caused a lowering of systolic pressure with reduced cardiac output and diastolic dysfunction whereas melatonin pretreatment significantly restored many of these parameters to normal. The findings document melatonin’s ability to provide cardio protection at a low pharmacological dose. Melatonin has virtually no toxicity which raises the possibility of this indole being a therapeutic treatment for ischemic heart disease.

Effect of Micropolarity on the Propagation of Shear Waves in a Piezoelectric Layered Structure

This paper studies the propagation of shear waves in a composite structure consisting of a piezoelectric layer perfectly bonded over a micropolar elastic half space. The general dispersion equations for the existence of shear waves are obtained analytically in the closed form. Some particular cases have been discussed and in one special case the relation obtained is in agreement with existing results of the classical –Love wave equation. The micropolar and piezoelectric effects on the phase velocity are obtained for electrically open and mechanically free structure. To illustrate the utility of the problem numerical computations are carried out by considering PZT-4 as a piezoelectric and aluminium epoxy as micropolar elastic material. It is observed that the micropolarity present in the half space influence the phase velocity significantly in a particular region. The micropolar effects on the phase velocity in the piezoelectric coupled structure can be used to design high performance acoustic wave devices.
