A New Improved Hybridized K-MEANS Clustering Algorithm with Improved PCA Optimized with PSO for High Dimensional Data Set

 Abstract— The day to day computation has made the data sets and data objects to grow large so it has become important to cluster the data in order to reduce complexity to some extent. K-means clustering algorithm is an efficient clustering algorithm to cluster the data, but the problem with the k-means is that when the dimension of the data set becomes larger the effectiveness of k-means is lost. PCA algorithm is used with k-means to counter the dimensionality problem. However K-means with PCA does not give much optimisation. It can be experimentally seen that the optimisation of k-means gives more accurate results. So in this paper we have proposed a PSO optimised k-means algorithm with improved PCA for clustering high dimensional data set.
Hybrid MIMO Architectures for Millimeter Wave Communications: Phase Shifters or Switches?

Hybrid analog/digital multiple-input multiple-output architectures were recently proposed as an alternative for fully digital-precoding in millimeter wave wireless communication systems. This is motivated by the possible reduction in the number of RF chains and analog-to-digital converters. In these architectures, the analog processing network is usually based on variable phase shifters. In this paper, we propose hybrid architectures based on switching networks to reduce the complexity and the power consumption of the structures based on phase shifters. We define a power consumption model and use it to evaluate the energy efficiency of both structures. To estimate the complete MIMO channel, we propose an open-loop compressive channel estimation technique that is independent of the hardware used in the analog processing stage. We analyze the performance of the new estimation algorithm for hybrid architectures based on phase shifters and switches. Using the estimate, we develop two algorithms for the design of the hybrid combiner based on switches and analyze the achieved spectral efficiency. Finally, we study the tradeoffs between power consumption, hardware complexity, and spectral efficiency for hybrid architectures based on phase shifting networks and switching networks. Numerical results show that architectures based on switches obtain equal or better channel estimation performance to that obtained using phase shifters, while reducing hardware complexity and power consumption. For equal power consumption, all the hybrid architectures provide similar spectral efficiencies.
Widely distributed MIMO radar beamforming for detecting targets with slow RCS fluctuations

In a widely distributed MIMO radar, the transmitters and the receivers are distributed so that they see a target from different aspects. The scattering from the target is therefore different for each transmitter-receiver pair. It is commonly assumed that a set of orthogonal waveforms are transmitted and the scattered waveforms are then separated using a matched filter to achieve diversity. In this paper, we propose a beamforming method for the widely distributed MIMO radar. Orthogonal waveforms are used initially for probing the target, i.e. to obtain information about the the target and the channel and a single waveform is then transmitted so that the SNR in the receivers is increased. Numerical simulations demonstrate that this will increase the probability of detecting the target.
SemSor: Combining Social and Semantic Web to Support the Analysis of Emergency Situations

In this paper we introduce SemSor, a system developed especially for the analysis of emergency situations. It constantly collects information from sources of the Social Web, maps it to unique resources in the Semantic Web and uses the annotated information as basis for the situation analysis. If an emergency situation needs to get analyzed, four steps are required: First, all information that is already known about this situation must be entered in the SemSor-GUI. Second, the entered information needs to be mapped to resources in the Semantic Web. Third, using these resources as starting nodes, a spreading activation is applied along the relationships within the Semantic Web to nd relevant Social Web information. And fourth, the newly identied information is visualized according to dierent dimensions and can be ltered and explored by the user. In an iterative process, new insights can be used to rene the query and thus improve the activated information until a comprehensive analysis of even complex situations is possible.
Fair Value Accounting : Political Obstacles ?

as well as their fair value, documenting how they tend to create obstacles in terms of the worldwide globalization process. More precisely, we focus on analyzing the amendment to IAS 39 for reclassifications of financial assets. Two objectives are being followed: to consider the amendment and its implications from the standard setting point of view and to afterwards quantify its effect on the EU companies. The first objective is reached by concluding that the amendment significantly altered IASB's credibility, while the second failed in completely convincing us about the economic grounding of the amendment.

Changes in Plantar Pressure While Running with a Jogging Stroller

Despite the common use of jogging strollers, only a few studies cover their influence on running patterns. Kinematic studies have shown differences in the upper body movement, while potential changes in plantar pressure remain unclear. Therefore, 30 healthy sport students were asked to run at a self-selected speed with and without a jogging stroller on a treadmill. Via bilateral insole pressure measurements, the plantar pressure distribution and the stride length were quantified. A significantly decreased pressure for running with a jogging stroller was found in the forefoot, metatarsus, inner edge, outer edge and for the total pressure of the left foot. The right foot showed similar significances for all foot areas except the metatarsus. Stride length was significantly shorter when running with a jogging stroller. As stride length and plantar pressure are known to correlate, the reduced stride length in running with a jogging stroller can partially explain the measured decrease in plantar pressure. Further, the partial weight-bearing, which is needed to keep the jogging stroller in line, can also contribute to the decrease in plantar pressure. Moreover, the unilateral weight-bearing enlarges the base of support and could also be a reason for the decrease in plantar pressure. In conclusion, our results show statistically significant changes in plantar pressure, but these are not of clinical importance as the effect sizes are very low. Therefore, no specific training recommendations for running with a stroller have to be made.
Information and communication technologies for people with disabilities

We also show how some educational technologies, largely inspired by Seymour Papert's theories, can be used to help people with disabilities. Among these technologies, we highlight a project involving the GoGoBoard, a small electronical device that can have sensors and actuators attached to it. The GoGoBoard was used by two students in their final undergraduate degree project, to build an intelligent bedroom. In this room, a person with physical disabilities, can control various things. As examples, the person can open/close the door, turn on/off the lights or turn on/off the air conditioning. All of that by simply pressing a touch button.
Supplementary Methods: Weighted Correlation Network Analysis

Comparing expression and methylation networks necessitates that the network nodes can be matched between expression and methylation networks. Since expression and methylation probe sets are very different, a simple approach is to aggregate (“collapse”) the probe-level data to gene-level data. To this end we use the function collapseRows [6] that selects a representative probe for each gene represented on the microarray. For expression data we use the probe with highest mean expression while for methylation data we use the probe with highest variance. This procedure resulted in expression profiles for 13384 genes and methylation profiles for 13569 genes, of which 10483 are common. We note that while the individual network analyses used the full sets of 13384 and 13569 genes, respectively, the preservation analysis only used the common subset of 10483 genes. Hence, the indicated numbers of genes in the modules are slightly different between the enrichment tables (Tables 4 and 5 in the main text) and the module preservation figures (Figures 2A, 2B, and the supplementary figure in Supplementary File 11).
Motion Planning and Control of Robot Manipulators

When a robot performs a task in an unstructured dynamic environment, it has to account for many factors. It should not only keep the track of where it is and how it should move, but also ensure that the kinematic, dynamic and task specific limitations are observed. It is also important that the robot can effectively avoid collisions with static and moving obstacles. In the current thesis we present design and implementation of an algorithm capable to face all these challenges. The system combines principles of dynamic roadmaps and elastic roadmaps frameworks, both of which are the state-of-art approaches to motion planning problem. The suggested solution is presented in the context of a broad overview of the literature in motion planning domain focusing on methodology of sample-based and feedback planning in dynamic environments. The implemented algorithm is applied to a 7-degree-of-freedom manipulator and is demonstrated and analyzed through a variety of simulated test scenarios. The result is an extensible and future-oriented planning system that can plan and execute movement between a starting and target position while preserving task constraints and reacting to environment changes in real time.
Virtual Micromagnetics: A Framework for Accessible and Reproducible Micromagnetic Simulation

Computational micromagnetics requires numerical solution of partial differential equations to resolve complex interactions in magnetic nanomaterials. The Virtual Micromagnetics project described here provides virtual machine simulation environments to run open-source micromagnetic simulation packages. These environments allow easy access to simulation packages that are often difficult to compile and install, and enable simulations and their data to be shared and stored in a single virtual hard disk file, which encourages reproducible research. Virtual Micromagnetics can be extended to automate the installation of micromagnetic simulation packages on non-virtual machines, and to support closed-source and new open-source simulation packages, including packages from disciplines other than micromagnetics, encouraging reuse. Virtual Micromagnetics is stored in a public GitHub repository under a three-clause Berkeley Software Distribution (BSD) license.
Toward Evaluation of Writing Style: Overly Repetitious Word Use

Automated essay scoring is now an established capability used from elementary school through graduate school for purposes of instruction and assessment. Newer applications provide automated diagnostic feedback about student writing. Feedback includes errors in grammar, usage, and mechanics, comments about writing style, and evaluation of discourse structure. This paper reports on a system that evaluates a characteristic of lower quality essay writing style: repetitious word use. This capability is embedded in a commercial writing assessment application, CriterionSM. The system uses a machine-learning approach with word-based features to model repetitious word use in an essay. System performance well exceeds several baseline algorithms. Agreement between the system and a single human judge exceeds agreement between two human judges.
ASSESSING THE CONDENSATE-DRAINAGE BEHAVIOR OF DEHUMIDIFYING HEAT EXCHANGERS

Contemporary compact heat exchangers often employ very high fin densities. In many air-conditioning applications such as automotive cooling, the heat exchanger operates to dehumidify the conditioned air. It has been observed that the amount of condensate retained on the air-side surface significantly increases with increased fin density. Retained condensate not only affects the thermal-hydraulic performance, but it also has adverse implications on the quality of conditioned air. Conventional wind tunnel experiments to assess performance are expensive. A method for characterizing water drainage from heat exchanger surfaces, the so-called dynamic dip test, is described. The dynamic dip test is explored as a fast and efficient method for comparative and screening studies for applications where off-cycle drainage is important. Results from more than 30 automotive-style heat exchangers are presented, and condensate drainage characteristics are explored to assess surface tension effects in inter-fin and louver gaps of highfin-density, compact heat exchangers.
Limiting factors in sub- 10 nm scanning-electron-beam lithography

Achieving the highest possible resolution using scanning-electron-beam lithography (SEBL) has become an increasingly urgent problem in recent years, as advances in various nanotechnology applications [F. S. Bates and G. H. Fredrickson, Annu. Rev. Phys. Chem. 41, 525 (1990); Black et al., IBM J. Res. Dev. 51, 605 (2007); Yang et al., J. Chem. Phys. 116, 5892 (2002)] have driven demand for feature sizes well into the sub-10nm domain, close to the resolution limit of the current generation of SEBL processes. In this work, the authors have used a combination of calculation, modeling, and experiment to investigate the relative effects of resist contrast, beam scattering, secondary electron generation, system spot size, and metrology limitations on SEBL process resolution. In the process of investigating all of these effects, they have also successfully yielded dense structures with a pitch of 12nm at voltages as low as 10keV.
Binge Eating in Males: A Sample Description and Treatment Outcome Study

Abstract An outcome study on inpatient treatment for binge-eating males was conducted (N = 50, average follow-up duration = 23 months). The sample differed from those described in studies of bulimia in males in that the majority of these subjects had no history of self-induced vomiting or use of laxatives or diuretics and were older and obese upon presentation for treatment. Follow-up measures indicated that these subjects responded well to inpatient treatment. Upon follow-up, subjects reported little medical or psychiatric resource utilization other than what was prescribed as aftercare, improvement in eating disorder-related medical conditions, good ratings of general mental health, and significant decreases in binge eating and other eating disorder-related behaviors over the follow-up duration. “Good” outcome patients, that is, subjects reporting substantial positive change in eating behavior

Feature types and object categories: Is sensorimotoric knowledge different for living and nonliving things?

ABSTRACT Some models of semantic memory claim that items from living and nonliving domains have different feature-type profiles. Data from feature generation and perceptual modality rating tasks were compared to evaluate this claim. Results from two living (animals, fruits/vegetables) and two nonliving (tools, vehicles) categories showed that sensorimotoric features were important in object knowledge across both domains. In addition, significant cross-domain similarities and within-domain differences indicated that feature profiles were not determined simply as a function of the living and nonliving domain distinction. The current data support a model of semantic memory rooted in perceptual and motor processes with reduced salience for the “living/nonliving” construct.
‘Do as we say but not as we do’: Organizational, professional and personal barriers to the receipt of support at work

Given the existence of an established literature on the costs of burnout to the well-being of the clinician and to the effectiveness of therapeutic interventions for the client, self-care amounts to sensible preventative action on the part of the mental health worker. This study focuses on experiences of clinical psychologists working in the National Health Service (NHS) in Britain. A two-stage qualitative study was designed which explored the attitudes and practices of this group of mental health workers towards the receipt of support at work. Analyses revealed that psychologists may be vulnerable to poor levels of self-care because they perceive the expression of support needs as psychologically threatening. Four themes emerged as significant factors in explaining the relationship between the receipt of support and psychological threat: Organizational devaluation of supportive work practices, ambivalent professional values, psychologists' own fears of being a client, and the perceived costs of the support process itself. An explanatory model describing the interrelationship between these factors is developed.
Classic Hodgkin lymphoma in pelvis

Rationale: Classic Hodgkin lymphoma with pelvic involvement is a rare entity. Diagnosis and treatment for such an uncommon disease are challenging. Here we report a special case of classic Hodgkin lymphoma in pelvis. Patient Concerns: A 20-year-old woman was admitted to our department due to left hip symptoms. The patient reported a history of drenching night sweats, low-grade fever, pruritic rash on the body, and an almost 15% weight loss during the previous 3 months. Diagnoses: Imaging studies revealed osteolytic destruction of the left hemi-pelvic with a huge soft-tissue mass. Open biopsy established the pathological diagnosis of classic Hodgkin lymphoma. Interventions: Considering the B symptom, bulky disease, and high risk of pathological fracture of the patient, we performed limb-salvage surgery and 6 cycles ABVD chemotherapy with 2 cycles before surgery. Outcomes: Up to now, at the 3-year follow-up, there is no sign of disease relapse and metastasis. Besides, her limb function recovered well. Lessons: Based on this case and literature we reviewed, diagnoses for primary bone Hodgkin lymphoma should be cautious. For the treatment, chemotherapy was the main treatment option. Classic Hodgkin lymphoma patients seldom received tumor resection surgery, but for the special bone classic Hodgkin lymphoma individual with a huge tumor volume and high risk of pathological fracture in our study, limb-salvage surgery based on ABVD chemotherapy provided a satisfying clinical outcome.
Universal School-Based Implementation of Screening Brief Intervention and Referral to Treatment to Reduce and Prevent Alcohol, Marijuana, Tobacco, and Other Drug Use: Process and Feasibility

Screening, Brief Intervention, and Referral to Treatment (SBIRT) is an evidence-based approach to reducing substance use in adolescents. An emerging literature shows the promise of school-based SBIRT. However, most school-based SBIRT has only targeted substance-using adolescents and used school-based health clinics, which most schools lack. This project aimed to describe the following: a model for implementing universal SBIRT in high schools without school-based clinics, reasons students most commonly endorsed for reducing or avoiding substance use, students’ perceptions of SBIRT, and students’ intentions to change substance use or remain abstinent following SBIRT. Participants were N = 2513, 9th to 10th grade students in 10 high schools. Students rated SBIRT positively and indicated substantial intentions to reduce or delay substance use following SBIRT. Results support SBIRT’s potential to delay substance use among current abstainers in addition to reducing substance use among current users. This project demonstrates SBIRT’s feasibility as a universal method in high schools without in-school clinics.
Legitimate peripheral irritations

Purpose – In 2010, the author published a practical critique of some of Karl Weick's writings, to which Weick offered a rejoinder. The purpose of this paper is to use his response as an occasion to reflect on the rhetorical conditions of critique in the sensemaking tradition.Design/methodology/approach – This paper provides a rhetorical analysis of Weick's response to the author's critique, showing that it is directed at the ethos of the critic. For the purpose of the analysis, ethos is conventionally defined as the character, competence and goodwill of the speaker.Findings – The analysis shows that Weick's dismissal of the author's critique suggests the lack of a “dwelling place” (the primordial sense of “ethos” in pre‐Socratic Greek) for critical scholarship in sensemaking research.Originality/value – All scholarly communities need a space for the critical evaluation of the claims their members make. In an attempt to establish such a place, the author counters the standard disciplinary pedagogy of sense.
