Data Mining of Social Media for Analysis of Product Review

Social media plays a crucial role in promoting different products. The data collected from the social media helps to improve the quality of products, and helps the customer to select the best product among available products. In this paper, an algorithm is developed based on text mining and TF-IDF (Term Frequency–Inverse Document Frequency) scores. In this paper, it is focused on removing unwanted words such as stop words, stemming words, then the processed data is used for finding sentiment words using NLTK (Natural Language Toolkit). The Stanford POS tagger is also used to tag the words into different categories like positive and negative. The proposed algorithm is implemented using JAVA NetBeans8.2 and achieved desired results. The proposed method can be expanded for the evaluation of different products based on customer reviews provided on the social media.
Contextualisation of ABAC Attributes through a Generic XACML Functionality Extension Mechanism

Authorisation solutions that exist today offer a broad range of functionality for defining complex access control policies. A common requirement that is not covered by these solutions is dynamically instantiated contexts in collaborative environments. This requirement is one of the research topics of the EU funded INTEGRATE project. This paper will focus on the solution proposed for the INTEGRATE project which is XACML based. The approach taken to make XACML context aware, is to enrich the XACML specification using a contextual extension through a generic mechanism, without changing the XACML language itself. This contextual extension operates on the XACML requests with ultimate goal to simplify the management of context aware policies.
Combining Features for Shape and Motion Trajectory of Video Objects for Efficient Content Based Video Retrieval

This paper proposes a system for content based video retrieval based on shape and motion features of the video object. We have used Curvature scale space for shape representation and Polynomial curve fitting for trajectory representation and retrieval. The shape representation is invariant to translation, rotation and scaling and robust with respect to noise. Trajectory matching incorporates visual distance, velocity dissimilarity and size dissimilarity for retrieval. The cost of matching two video objects is based on shape and motion features, to retrieve similar video shots. We have tested our system on standard synthetic databases. We have also tested our system on real world databases. Experimental results have shown good performance.
UvA-DARE ( Digital Academic Repository ) Energy Return on Energy Invested ( ERoEI ) for photovoltaic solar systems in regions of moderate insolation

A recent paper by Ferroni and Hopkirk (2016) asserts that the ERoEI (also referred to as EROI) of photovoltaic (PV) systems is so low that they actually act as net energy sinks, rather than delivering energy to society. Such claim, if accurate, would call into question many energy investment decisions. In the same paper, a comparison is also drawn between PV and nuclear electricity. We have carefully analysed this paper, and found methodological inconsistencies and calculation errors that, in combination, render its conclusions not scientifically sound. Ferroni and Hopkirk adopt ‘extended’ boundaries for their analysis of PV without acknowledging that such choice of boundaries makes their results incompatible with those for all other technologies that have been analysed using more conventional boundaries, including nuclear energy with which the authors engage in multiple inconsistent comparisons. In addition, they use out-dated information, make invalid assumptions on PV specifications and other key parameters, and conduct calculation errors, including double counting. We herein provide revised EROI calculations for PV electricity in Switzerland, adopting both conventional and ‘extended’ system boundaries, to contrast with their results, which points to an order-ofmagnitude underestimate of the EROI of PV in Switzerland by Ferroni and Hopkirk. http://dx.doi. org/10.1016/j.enpol. 2016.12. 042 Received 4 June 2016; Received in revised form 20 December 2016; Accepted 22 December 2016 DOI of original article: http://dx.doi. org/10.1016/j.enpol. 2016.03. 034 ⁎ Corresponding author.

The non-existence of (104, 22;3, 5)-arcs

Using some recent results about multiple extendability of arcs and codes, we prove the nonexistence of $(104,22)$-arcs in $PG(3,5)$. This implies the non-existence of Griesmer $[104,4,82]_5$-codes and settles one of the four remaining open cases for the main problem of coding theory for $q=5,k=4,d=82$.
Transcription Program of Murine Gammaherpesvirus 68

ABSTRACT Murine gammaherpesvirus 68 (MHV-68 [also referred to as γHV68]) is phylogenetically related to Kaposi's sarcoma-associated herpesvirus (KSHV [also referred to as HHV-8]) and Epstein-Barr virus (EBV). However, unlike KSHV or EBV, MHV-68 readily infects fibroblast and epithelial cell lines derived from several mammalian species, providing a system to study productive and latent infections as well as reactivation of gammaherpesviruses in vivo and in vitro. To carry out rapid genome-wide analysis of MHV-68 gene expression, we made DNA arrays containing nearly all of the known and predicted open reading frames (ORFs) of the virus. RNA obtained from an MHV-68 latently infected cell line, from cells lytically infected with MHV-68 in culture, and from the lung tissue of infected mice was used to probe the MHV-68 arrays. Using a tightly latent B-cell line (S11E), the MHV-68 latent transcription program was quantitatively described. Using BHK-21 cells and infected mice, we demonstrated that latent genes are transcribed during lytic replication and are relatively independent of de novo protein synthesis. We determined that the transcription profiles at the peak of lytic gene expression are similar in cultured fibroblast and in the lung of infected mice. Finally, the MHV-68 DNA arrays were used to examine the gene expression profile of a recombinant virus that overexpresses replication and transcription activator (RTA), C-RTA/MHV-68, during lytic replication in cell culture. The recombinant virus replicates faster then the parental strain and the DNA arrays revealed that nearly every MHV-68 ORF examined was activated by RTA overexpression. Examination of the gene expression patterns of C-RTA/MHV-68 over a time course led to the finding that the M3 promoter is RTA responsive in the absence of other viral factors.
Passive Phase Shifter for W-Band Applications using Liquid Crystals

In this paper a ridged waveguide phase shifter at W-band frequencies is presented. A taper matches the ridged waveguide phase shifter to the rectangular waveguide feed. Three different liquid crystals (LC) are used: a quasi-standard LC K15, a highly anisotropic mixture MDA-03-2844, and a dual-frequency switching LC MDA-05-1132, all synthesized by Merck KgaA. The return loss of the phase shifter device is always below -10dB in the whole W-band. The maximum achievable figure-of-merit of these materials is 78deg/dB at 108 GHz
Impact of a Cleft Lip and/or Palate on Maternal Stress and Attachment Representations

Objective The announcement, prenatally or at birth, of a cleft lip and/or palate represents a challenge for the parents. The purpose of this study is to identify parental working internal models of the child (parental representations of the child and relationship in the context of attachment theory) and posttraumatic stress disorder symptoms in mothers of infants born with a cleft. Method The study compares mothers with a child born with a cleft (n = 22) and mothers with a healthy infant (n = 36). Results The study shows that mothers of infants with a cleft more often experience insecure parental working internal models of the child and more posttraumatic stress symptoms than mothers of the control group. It is interesting that the severity or complexity of the cleft is not related to parental representations and posttraumatic stress disorder symptoms. The maternal emotional involvement, as expressed in maternal attachment representations, is higher in mothers of children with a cleft who had especially high posttraumatic stress disorder symptoms, as compared with mothers of children with a cleft having fewer posttraumatic stress disorder symptoms. Discussion Mothers of children with a cleft may benefit from supportive therapy regarding parent-child attachment, even when they express low posttraumatic stress disorder symptoms.
Developmental Time Course in Human Infants and Infant Monkeys, and the Neural Bases of, Inhibitory Control in Reaching a

Development appears to proceed by destruction and inhibition, as well as by construction and acquisition. For example, neural development involves, in part, pruning back an oversupply of neurons and an exuberance of axonal projections (see, e.g., Frost, this volume; Innocenti & Clarke, 1984). There are more nerve cells at birth in the neocortex of monkeys and humans than at any time thereafter (e.g., Rakic, 1974; 1985). Motor development and cognitive development, likewise, are made possible, in part, by the inhibition of reflexive and automatic reactions (e.g., Diamond & Gilbert, 1989). More and more regions of frontal cortex are being found to play a role in inhibition, although various subdivisions of frontal cortex appear to participate in different aspects of inhibition. Frontal cortex is by far the largest area of cortex in the human brain, it has increased the most in size (and in the proportion of brain mass devoted to it) over the course of evolution, and it takes longer to reach maturity than any other area of the brain (frontal cortex only becomes fully mature around puberty [e.g., Diamond, in press, a]). There is general agreement that the most anterior regions of frontal cortex (i.e., prefrontal cortex) subserve the highest cognitive abilities, the crowning intellectual achievements of the human race. The role of frontal cortex in inhibition is probably critical to its ability to subserve complex cognitive operations. Take, for example, the importance of prefrontal cortex for focusing attention. The role of frontal cortex in aiding attention appears to depend on the inhibitory functions of frontal cortex. Frontal cortex activity is critical to reduce distractibility

Crosslinking CD4 by human immunodeficiency virus gp120 primes T cells for activation-induced apoptosis

During human immunodeficiency virus (HIV) infection there is a profound and selective decrease in the CD4+ population of T lymphocytes. The mechanism of this depletion is not understood, as only a small fraction of all CD4+ cells appear to be productively infected with HIV-1 in seropositive individuals. In the present study, crosslinking of bound gp120 on human CD4+ T cells followed by signaling through the T cell receptor for antigen was found to result in activation-dependent cell death by a form of cell suicide termed apoptosis, or programmed cell death. The data indicate that even picomolar concentrations of gp120 prime T cells for activation-induced cell death, suggesting a mechanism for CD4+ T cell depletion in acquired immune deficiency syndrome (AIDS), particularly in the face of concurrent infection and antigenic challenge with other organisms. These results also provide an explanation for the enhancement of infection by certain antibodies against HIV, and for the paradox that HIV appears to cause AIDS after the onset of antiviral immunity.
Reliable and scalable technique with efficiency in hybrid Network

Next generation networks aim in omnipresent computing in which several networks which are homogeneous or heterogeneous in nature can be combined to obtain or access services which are present in other type of networks with seamless connectivity and without disruption in working. MANETs are used for maintaining connectivity with Multi Manet Gateway (MMGW) node. MMGW Node through which only, all remaining devices can communicate via gateways which are present in different networks. Modified AODV routing protocol with gateway initialization and selection is considered. In our work we proposed reliable, energy efficient and scalable technique using MMGW node concept and incorporated link stability and path stability factors in route selection and for a mobile device to maintain connectivity during movement a combination model is proposed. A simulation scenario is developed and performance analysis is done for that comparison of working of MMGW under diverse conditions.
Effect of Masked Hypertension on Aortic Elastic Properties

Aortic stiffness is increased in patients with sustained hypertension (SH). The aim of this study was to investigate the relationship between aortic elastic properties and masked hypertension (MH). We evaluated aortic elastic properties in 35 individuals with MH, 35 patients with SH, and 35 normotensive healthy volunteers using transthoracic Doppler echocardiography. All aortic distensibility values were carried out at the same time or immediately after the blood pressure (BP) measurement. Baseline clinical and demographic characteristics of the patients were similar in all three groups. Aortic stiffness index and elastic modulus values were higher in MH group compared to SH group and control group (8.9 ± 6.3 vs. 5.4 ± 2.2 vs. 4.2 ± 2.5, P < .001 and 9.0 ± 6.3 vs. 6.4 ± 2.5 vs. 4.1 ± 2.4, P < .001, respectively). Aortic strain values were lower in MH group compared to SH group and control group (7.4 ± 5.3 vs. 9.5 ± 4.1 vs. 14.6 ± 7.1, P < .001, respectively). Aortic distensibility values were lower in MH and SH groups compared to controls (3.1 ± 1.9 vs. 3.7 ± 1.6 vs. 6.4 ± 3.4, P < .001, respectively). Furthermore, diastolic aortic diameter, left ventricular mass index, interventricular septum, and posterior wall thickness were higher in MH and SH groups when compared to controls. This study shows that masked hypertensive patients are at higher risk of “aortic” stiffness, a risk factor for cardiovascular morbidity and mortality, than normotensive and sustained hypertensive patients.
Stabilization and H∞ control of switched stochastic systems

This paper is concerned with the stabilization and Hinfin control problems for continuous-time switched stochastic systems. By applying the average dwell time method and the piecewise Lyapunov function technique, sufficient conditions are first proposed, which guarantee the unforced switched stochastic system to be mean-square exponentially stable with a prescribed Hinfin performance. Then, the stabilization and Hinfin control problems are solved.
Optimal control of discrete-time linear fractional-order systems with multiplicative noise

ABSTRACT A finite horizon linear quadratic (LQ) optimal control problem is studied for a class of discrete-time linear fractional systems (LFSs) affected by multiplicative, independent random perturbations. Based on the dynamic programming technique, two methods are proposed for solving this problem. The first one seems to be new and uses a linear, expanded-state model of the LFS. The LQ optimal control problem reduces to a similar one for stochastic linear systems and the solution is obtained by solving Riccati equations. The second method appeals to the principle of optimality and provides an algorithm for the computation of the optimal control and cost by using directly the fractional system. As expected, in both cases, the optimal control is a linear function in the state and can be computed by a computer program. A numerical example and comparative simulations of the optimal trajectory prove the effectiveness of the two methods. Some other simulations are obtained for different values of the fractional order.

RETHINKING THE RESEARCH PARADIGMS FOR ANALYSING TAX COMPLIANCE BEHAVIOUR

In this paper we give our perspective on the different paradigms that have shaped – and seem likely to shape in the future – research in the field of tax compliance behavior. These research paradigms include viewing tax evasion as a decision under risk made by a single taxpayer, as a social dilemma in which there is a tension between individual interests (e.g., cheating on one's taxes) and collective goals (e.g., providing public goods), as a series of decisions made by many different types of taxpayers, and as a psychological contract between tax authorities and taxpayers. We argue that these different paradigms require that particular attention be paid to the main "actors in the field", which involves going beyond a focus on a single taxpayer to consider other taxpayers, tax accountants, the tax authorities, and the government. The ways in which these actors interact in different climates, especially the dynamics of power and trust between the actors, must also be considered. We conclude with a discussion of a framework – the "slippery slope framework" – that attempts to synthesize these different research paradigms. Throughout, we illustrate our arguments by reference to research that focuses especially on the European experience.
Photoaging of human skin

Chronic sun exposure causes photoaging of human skin, a process that is characterized by clinical, histological and biochemical changes which differ from alterations in chronologically aged but sun‐protected skin. Within recent years, substantial progress has been made in unraveling the underlying mechanisms of photoaging. Induction of matrix metalloproteinases as a consequence of activator protein (AP)‐1 and nuclear factor (NF)‐κB activation as well as mutations of mitochondrial DNA have been identified recently. This has increased our understanding of photoaging significantly and has led to new prophylactic and therapeutic strategies aimed at the prevention and repair of the detrimental effects of chronic sun‐exposure on the skin.
Relationship between social interaction bids and language in late talking children

Abstract Purpose: The aim of this paper is to explore the relationship between language development and the frequency of social interaction (SI) behaviours during language acquisition in late-talking (LT) children who exhibit delays in expressive vocabulary development but have age-appropriate cognitive skills. Method: The research consists of a longitudinal study with a first test followed by two re-tests 5 months apart, in which LT children were compared to 5-months-younger typically-developing (TD) children. Result: Data showed that LT children performed significantly fewer initiation of SI behaviours, but no differences between groups in responding to SI behaviours were observed. Furthermore, LT children who have lower language comprehension scores initiate social interaction more frequently. Conclusion: The results showed that LT children seem to be less active in starting social interaction and participation, but, once they get involved, they respond similarly to TD children of comparable expressive language competence. Additionally, the correlation pattern between the frequency of SI behaviours and language functions showed that LT toddlers with more prominent receptive language delay are more interested in initiating interaction with their partner, thus suggesting that they need a partner's “scaffolding” to overcome this lack.
On the modal resonant properties of microstrip antennas

The chosen rectangular and fractal microstrip patch antennas above an infinite ground plane are analyzed by the Theory of characteristic modes. The resonant frequencies and radiation Q are evaluated. An method by G. Vandenbosch for rigorous evaluation of the radiation Q is employed for modal currents on a Rao-Wilton-Glisson (RWG) mesh. It is found that the resonant frequency of a rectangular patch antenna with a dominant mode presents quite complicated behaviour including having a minimum at a specific height. Similarly, as predicted from the simple wire model, the radiation Q exhibits a minimum too. It is observed that the presence of out-of-phase currents flowing along the patch antenna leads to a significant increase of the Q-factor.
Feasibility of a new community-based geriatric intervention programme: An exploration of experiences of GPs, nurses, geriatricians, patients and caregivers

Purpose. To determine the feasibility of the Dutch Geriatric Intervention Programme (DGIP) in primary care. Within the DGIP, a nurse cooperates with a General Practitioner (GP) and a clinical geriatrician to assess and manage care for community-living older patients. The aim of this study was to describe both views of care receivers and those of professionals in order to identify facilitating factors and barriers for implementation of the DGIP. Method. Combined quantitative and qualitative data collection methods were used. Pre- and post-questionnaires were taken from GPs (n = 15), nurses (n = 6) and geriatricians (n = 2). These professionals were also interviewed. In addition patients (n = 11 out of total n = 54) and their carers (n = 37) were interviewed. Results. GPs appreciated the support by the DGIP for problems in cognition, mood and mobility. Lack of knowledge and time restriction was the cause of their incapability at that point. In the cooperation between professionals, nurses felt that they had to initiate the contact. Personal contact helped the mutual communication. Involving the carer of the patient proved very important. All disciplines found this of crucial importance in order to deliver a tailored intervention and create conditions for optimal care. Barriers, for which the programme was tailored during the implementation, were: resistance in referrals of patients to the programme, nurses' and GPs' knowledge of diagnostic tests, communication problems and insufficient involvement of caregivers. Conclusions. The implementation of the DGIP was feasible, but several barriers need ongoing attention by implementation, like communication between disciplines.
