THE EFFECT OF THE DATA STORAGE TECHNIQUES ON THE ANALYSIS PERFORMANCE IN THE DATA MINING STUDIES: A SAMPLE APPLICATION WITH WEKA

In this study, the data storage techniques which are necessary to perform the data mining applications have been anaysed. In the data mining applications, the data are processed through some stages until the analysis stage. The proper performance of these stages affects both the accuracy of the analysis and the performance. Also, the analyses should be carried out the with the appropriate hardware. The effective use of the physical memory and the processor capacity bears a lot of importance in terms of analysis period and cost. In the study, database and file environment, which are two types of the data, which are to be processed through the data mining applications, have been examined. Some analyses have been carried out on a sample data cluster for this operation. It has been searched whether there is a connection between the size of the data cluster and storage environments through a gradual increase in the data analysed. For this purpose, a cluster composed of 25 million data has been put into analysis. Firstly, an analysis for two types storage environments has been performed by increasing these data with the use of Navie Bayes algorithm. The results obtained have been grouped as physical memory and the CPU usage. Secondly, the performance assessment has been examined in relation to time through the record of the analysis periods . The data obtained from the analyses in the database and the file environments have been indicated and evaluated in the final chapter of our study.
Attitudes of sixth form female students toward the IT field

It is well known that girls are not interested in computer science, information systems (IS), and software engineering studies. While the underlying reasons for this phenomenon have been studied in the US, Canada, and Australia, only a few studies have been carried out in Europe and in Scandinavia. To fill this gap in the research, we have analyzed the qualitative responses of 64 female sixth form students concerning their attitudes towards studying information technology (IT), including computer science, information systems, and software engineering disciplines, and their views about IT as a profession. The results suggest that the IT field is seen in quite a positive light by the girls. Although many of the respondents do not consider IT to be their profession, they nevertheless have positive attitudes towards the field. According to the respondents, the field is growing and developing; it is respected, and seen as the field of the future. Girls who want to become IT professionals see that the profession entails good employment possibilities and benefits and is respected. Some girls have negative views towards the field. These views illustrate the underlying reasons why these girls do not want to study IT. The girls did not perceive the field to be human-related (the work is only computer-related, according to the respondents). The need for skills in mathematics and physics are also listed as key reasons why some girls do not want to become IT students. The results of the study suggest that there is a need to clarify among sixth form students the fact that IT jobs can be divided into computer science, information systems, and software engineering, all of which require different competences.
Using computational models to study texture representations in the human visual system.

Traditionally, human texture perception has been studied using artificial textures made of random-dot patterns or abstract structured elements. At the same time, computer algorithms for the synthesis of natural textures have improved dramatically. The current study seeks to unify these two fields of research through a psychophysical assessment of a particular computational model, thus providing a sense of what image statistics are most vital for representing a range of natural textures. We employ Portilla and Simoncelli’s 2000 model of texture synthesis for this task (a parametric model of analysis and synthesis designed to mimic computations carried out by the human visual system). We find an intriguing interaction between texture type (periodic v. structured) and image statistics (autocorrelation function and filter magnitude correlations), suggesting different processing strategies may be employed for these two texture families under pre-attentive viewing.

Instruction Cache Design for Energy-Aware Embedded Processors by Using Backward Branch Information

Continuing advances in semiconductor technology and demand for higher performance will lead to more powerful embedded processors. Unfortunately, as the computing power of a processor increases, energy consumption in the processor dramatically increases. For this reason, energy efficiency should be considered together with performance when designing embedded processors. This paper proposes a new energy-aware instruction cache design using backward branch information to reduce the energy consumption in a embedded processor, since instruction caches consume a significant fraction of the on-chip energy. Proposed instruction cache is composed of two caches: a large main instruction cache and a small loop instruction cache. Proposed technique enables the selective access between the main instruction cache and the loop instruction cache to reduce the number of accesses to the main instruction cache, leading to good energy efficiency. We evaluated the energy efficiency by running cycle accurate simulator, SimpleScalar, with power parameters obtained from CACTI. Analysis results show that the proposed cache reduces the energy consumption by 20% on the average, compared to the traditional cache.
The caregiving context in institution-reared and family-reared infants and toddlers in Romania.

BACKGROUND We assess individual differences in the caregiving environments of young children being raised in institutions in Romania in relation to developmental characteristics such as physical growth, cognitive development, emotional expression, and problem and competence behaviors. METHOD Videotaped observations of the child and favorite caregiver in their 'home' environment were coded for caregiving quality, and this was related to child characteristics. Child emotional reactivity was assessed during responses to interactional tasks. Cognitive development was assessed from child responses to the Bayley Scales of Infant Development. Data regarding problem behaviors and competence were obtained from caregiver report. Children reared in institutions were compared on all of these measures to never institutionalized children to assist gauging degree of impairment. RESULTS Children raised in institutions demonstrated marked delays in cognitive development, poorer physical growth, and marked deficits in competence. Individual differences in caregiving environment were associated with cognitive development, competence, and negative behavior among these young children being reared in institutions. CONCLUSIONS These data confirm previous findings regarding deficits associated with institutional care and extend our understanding of the impact of individual differences in caregiving quality on the development of young children in institutions.
Robotic companion lead the way!

During last years, robotic research has explored Human-Robot interactions especially for the challenge of the robot companion. This type of robot would be equipped with perception, motion, and manipulation among other skills, to be help humans in daily tasks. Guidance is one of the tasks that the robot companion must perform. This paper describes Robbie, a wheeled robot companion uses for guiding missions. The Robbie combines visual clues, voice, distance and PC input to detect humans and features in the environment. To complete its task Robbie could receive extra information from smart beacons located in the building. The paper also explores two modalities to the guiding missions. Finally, experiments are presented in order to highlight the relevance of the approach.
Improving public auditability, data possession in data storage security for cloud computing

Cloud computing is Internet based technology where the users can subscribe high quality of services from data and software that resides solely in the remote servers. This provides many benefits for the users to create and store data in the remote servers thereby utilizing fewer resources in client system. However management of the data and software may not be fully trustworthy which possesses many security challenges. One of the security issues is the data storage security where frequent integrity checking of remotely stored data is carried out. RSA based storage security (RSASS) method uses public auditing of the remote data by improving existing RSA based signature generation. This public key cryptography technique is widely used for providing strong security. Using this RSASS method, the data storage correctness is assured and identification of misbehaving server with high probability is achieved. This method also supports dynamic operation on the data and tries to reduce the server computation time. The preliminary results achieved through RSASS, proposed scheme outperforms with improved security in data storage when compared with the existing methods.
An Omnidirectional Polarization Detector Based on a Metamaterial Absorber

The theory, design, simulation, fabrication, and performance of an omnidirectional polarization detector (PD) with two resonances located in the X and Ka ranges based on a metamaterial absorber (MMA) are presented in this paper. The sandwich structure of PD is composed of 0.1 μm periodic “I” shaped patches on the metasurface, a dielectric of 200 μm FR-4 on the interlayer, and a 0.3 μm copper film on the substrate. PD absorptivity is first used to reflect and describe the polarization of the incident wave. The numerical results, derived from the standard full wave finite integration technology (FIT) of CST 2015, indicates that the designed PD shows polarization sensitivity at all incidence angles. The effects on absorptivity produced by the incidence angles, polarization angles, and materials are investigated. The amplitude of absorptivity change caused by polarization reaches 99.802%. A laser ablation process is adopted to prepare the designed PD on a FR-4 board coated with copper on the double plane with a thickness that was 1/93 and 1/48 of wavelength at a resonance frequency of 16.055 GHz and 30.9 GHz, respectively. The sample test results verify the designed PD excellent detectability on the polarization of the incident waves. The proposed PD, which greatly enriches the applications of metamaterials in bolometers, thermal images, stealth materials, microstructure measurements, and electromagnetic devices, is easy to mass produce and market because of its strong detectability, ultrathin thickness, effective cost, and convenient process.
5WTAG: Detecting the Topics of Chinese Microblogs Based on 5W Model

A hash tag is an important metadata in micro blogs and used to mark topics or index messages. However, statistics show hash tags are absent from most of the micro blogs. It poses great challenges to the retrieve and analysis of these tagless micro blogs. In this paper, we summarize the similarity between micro blogs and short message news, and then propose an algorithm named 5WTAG for detecting micro blog topics based on 5W (When, Where, Who, What, how) model. Since 5W attributes are the core components in event description, it is guaranteed theoretically that 5WTAG can extract the semantics of the micro blogs properly. We introduce the detailed procedure of 5WTAG in this paper including the candidate hash tag construction and recommendation computation. Finally, we verify the semantical correctness of the candidate hash tags as well as the effectiveness of recommendation computation using the real data set from Sina Weibo.
CART: Communication-Aware Routing Technique for Application-Specific NoCs

Networks on Chip (NoCs) have been shown as an efficient solution to the complex on-chip communication problems derived from the increasing number of processor cores. One of the key issues in the design of NoCs is the reduction of both area and power dissipation. As a result, two-dimensional meshes have become the preferred topology, since it offers low and constant link delay. Unfortunately, manufacturing defects or even real-time failures often make the resulting topology to become irregular, preventing the use of traditional routing algorithms. This scenario shows the need for topology-agnostic routing algorithms that provide a valid routing solution when applied over any topology. Moreover, in order to deal with run-time failures, the routing algorithm should be able to fit runtime constraints. This paper proposes a new communication-aware routing technique, referred to as CART, that optimizes the network performance for application-specific NoCs. CART combines a flexible, topology-agnostic routing algorithm with a communication-aware mapping technique that matches the traffic generated by the application with the available network bandwidth. Since the mapping technique can be pruned as needed in order to fit either quality function values or time constraints, CART can be adapted to fit with different computational costs. The evaluation results show that CART significatively improves network performance in terms of both latency and power consumption.

An approach to automated reparation of failed proof attempts in propositional linear logic sequent calculus

In many application areas of automated reasoning it is not sufficient to show that a given assertion is true. A good reasoning system should include tools not only for the generation of proofs, but also for the analysis of and manipulations with unsuccessful proof attempts. This paper focuses on the development of automated techniques for the transformation of a finite, failed sequent proof attempt D (in one-sided propositional linear logic) into a complete proof which retains the order of sequent rules of D and whose conclusion contains the conclusion of D. An algorithm is developed which replaces each non-axiom leaf ⊢ Δ with a proof of ⊢ Δ, F where F is formula dependent on Δ.
VEGF164(165) as the pathological isoform: differential leukocyte and endothelial responses through VEGFR1 and VEGFR2.

PURPOSE Vascular endothelial growth factor (VEGF) induces angiogenesis and vascular permeability and is thought to be operative in several ocular vascular diseases. The VEGF isoforms are highly conserved among species; however, little is known about their differential biological functions in adult tissue. In the current study, the inflammatory potential of two prevalent VEGF isoform splice variants, VEGF(120(121)) and VEGF(164(165)), was studied in the transparent and avascular adult mouse cornea. METHODS Controlled-release pellets containing equimolar amounts of VEGF(120) and VEGF(164) were implanted in corneas. The mechanisms underlying this differential response of VEGF isoforms were explored. The response of VEGF in cultured endothelial cells was determined by Western blot analysis. The response of VEGF isoforms in leukocytes was also investigated. RESULTS VEGF(164) was found to be significantly more potent at inducing inflammation. In vivo blockade of VEGF receptor (VEGFR)-1 significantly suppressed VEGF(164)-induced corneal inflammation. In vitro, VEGF(165) more potently stimulated intracellular adhesion molecule (ICAM)-1 expression on endothelial cells, an effect that was mediated by VEGFR2. VEGF(164) was also more potent at inducing the chemotaxis of monocytes, an effect that was mediated by VEGFR1. In an immortalized human leukocyte cell line, VEGF(165) was found to induce tyrosine phosphorylation of VEGFR1 more efficiently. CONCLUSIONS Taken together, these data identify VEGF(164(165)) as a proinflammatory isoform and identify multiple mechanisms underlying its proinflammatory biology.
Shot aggregating strategy for near-duplicate video retrieval

In this paper, we propose a new strategy for near-duplicate video retrieval that is based on shot aggregation. We investigate different methods for shot aggregation with the main objective to solve the difficult trade-off between performance, scalability and speed. The proposed short aggregation is based on two steps. The first step consists of keyframes selection. And the second one is the aggregation of the keyframes per shot. The aggregation is performed by applying Fisher vector on the descriptors computed on the selected keyframes. We demonstrate that the scalability and the speed are tackled by a sparse video analysis approach (i.e. extracting only few keyframes) combined with shot aggregation, while the performance is discussed around the choice of the aggregation strategy. The performance is evaluated on the CC_WEB_VIDEO dataset that is designed for the near-duplicate video retrieval assessment and for which some experiments have been conducted by different authors.
A Phenomenological Study on Threshold Improvement via Spatial Coupling

Kudekar et al. proved an interesting result in low-density parity-check (LDPC) convolutional codes: The belief-propagation (BP) threshold is boosted to the maximum-a-posteriori (MAP) threshold by spatial coupling. Furthermore, the authors showed that the BP threshold for code-division multiple-access (CDMA) systems is improved up to the optimal one via spatial coupling. In this letter, a phenomenological model for elucidating the essence of these phenomenon, called threshold improvement, is proposed. The main result implies that threshold improvement occurs for spatially-coupled general graphical models.
Fill in Occlusion Regions on Remotely Sensed Images Using Texture Synthesis Technique

Texture synthesis is a technique of generate new large image, from a small sample, that different from the original but has the same visual appearance. This technique is very valuable for filling missing information in images. In this paper, we apply Markov Random Fields (MRF) based texture synthesis technology to fill in occlusion areas on remotely sensed images. In order to improve the quality of results, we use GIS vector data to help to fill in the occlusion regions. Experiments show that the proposed method can obtain satisfying results and is practical in remote sensing application.
Cotilting modules and bimodules

Cotilting theory is a generalization of Morita duality in a sense that is analogous to that in which tilting theory is a generalization of Morita equivalence. Indeed, cotilting modules first appeared as vector space duals of tilting modules over finite dimensional algebras (see, e.g., [H, IV, 7.8]), just as injective cogenerators are such duals of progenerators. Later, R.R. Colby [Cb1] studied finitely generated cotilting bimodules over noetherian rings, proving that they induce finitistic generalized Morita dualities, similar to the finite dimensional algebra case. More recently, in [Cb2] he investigated a more general class of representable dualities, namely (nonfinitistic) generalized Morita dualities. He proved that the existence of such a duality implies the existence of a second pair of functors between classes that complement the reflexive ones, obtaining a result which is close to a dual form of the celebrated Tilting Theorem [BrBu], [HaRi]. For arbitrary rings R and S, a Morita duality between left S-modules and right R-modules is given by the contravariant Hom functors induced by a so called Morita bimodule SWR, namely, one such that (i) the classes of W -reflexive modules contain RR, WR, SS and SW , and are closed under submodules, factor modules and extensions; or, equivalently, (ii) SWR is balanced, and WR and SW are injective cogenerators. Colby’s generalized Morita dualities in [Cb2] are those induced by a bimodule SUR such that a natural weakening of (i) holds (just closure under factor modules is left out). Generalizing the notion of injective cogenerator, the authors of [CpDeTo] and [CpToTr] defined a cotilting module UR over a ring R as one such that Cogen(UR) = Ker ExtR(−, UR). In [CpDeTo, Proposition 1.7] it is shown that this notion is dual to that of tilting module by means of the following
Non-photorealistic outdoor scene rendering: techniques and application

Many researches in non-photorealistic rendering (NPR) have been done to investigate a variety of techniques to simulate the styles of hand-drawn artists. Many applications in industrial, architectural animated film production, technical design, and computer graphics designs have focused on rendering 3D models to depict non-photorealism. Most of them are based on rendering characters and object-based. This paper investigates on non-photorealistic rendering techniques for 3D outdoor scenes. Outdoor scene composed of a large extent of natural phenomena of landscapes, plants, trees, mountains, buildings, and many more. Techniques discussed in this paper include silhouette and cartoon-shaded renderings. Silhouette rendering implements brute force approach to determine the silhouette edges. Cel-shading algorithm in cartoon rendering renders the objects in the scene by manipulating directional or positional lightings with texture-shaded to give the scene cartoon look.
Angiofil®‐mediated visualization of the vascular system by microcomputed tomography: A feasibility study

Visualization of the vascular systems of organs or of small animals is important for an assessment of basic physiological conditions, especially in studies that involve genetically manipulated mice. For a detailed morphological analysis of the vascular tree, it is necessary to demonstrate the system in its entirety. In this study, we present a new lipophilic contrast agent, Angiofil®, for performing postmortem microangiography by using microcomputed tomography. The new contrast agent was tested in 10 wild‐type mice. Imaging of the vascular system revealed vessels down to the caliber of capillaries, and the digital three‐dimensional data obtained from the scans allowed for virtual cutting, amplification, and scaling without destroying the sample. By use of computer software, parameters such as vessel length and caliber could be quantified and remapped by color coding onto the surface of the vascular system. The liquid Angiofil® is easy to handle and highly radio‐opaque. Because of its lipophilic abilities, it is retained intravascularly, hence it facilitates virtual vessel segmentation, and yields an enduring signal which is advantageous during repetitive investigations, or if samples need to be transported from the site of preparation to the place of actual analysis, respectively. These characteristics make Angiofil® a promising novel contrast agent; when combined with microcomputed tomography, it has the potential to turn into a powerful method for rapid vascular phenotyping.
