A 360-Degree View of a Hospital by Analysing Patient’s Online Reviews Using Fuzzy Sentiment Analysis

Millions of people use Internet for developing new skills, booking online tickets, socialising, etc. Out of the sundry activities, giving online reviews by customers has become very customary these days and the fastest medium to make one’s voice heard. With the advent of analytics, more specifically, text mining, the online reviews of the customers have made a huge difference in shaping the future strategies of the companies and have also helped them to study the customer responses of their rivals. In an effort to help hospitals analyse the patient’s reviews present online on various social media platforms, this paper analyses the 659 reviews of people across the nation, on one of the best medical college and hospital of India, All India Institute of Medical Sciences, New Delhi. An attempt is made in this article to develop fuzzy sentiment analysis model with integration of naïve base classifier, which helps to analyse reviews of different hospitals and can come up with their own social media competitive analysis strategy. The results reveal the value text mining can bring to the table for any hospital and the immense business value that it holds.

Review of Data Mining for Twitter Data Analysis

In today’s life Twitter, Facebook, Google are well known social sites that many uses for different purposes. Social sites are the fastest medium which delivers news to user as compared to the new paper and television. One among the online social networks like Twitter, has quickly gained fame as it provides people with the opportunity to communicate and share messages known as “tweets”. Tremendous value lies in automated analysis and data mining of such vast and diverse data to derive meaningful insights, which carries potential opportunities for businesses, consumers, product survey and political survey. In the proposed system of analysis of the tweets, a search query for topic is provided to extract required data using ‘clustering algorithm’ in machine learning. The unique advantage of using machine learning is that once an algorithm knows what to do with the information, it can do its job automatically. To deduce for a search query, the proposed system extracts feature from the tweets like keywords in tweets, number of words in tweets. The output tweet list can further be used for analysis for business improvement or for surveys.

Twitter Event Summarization Using Phrase Reinforcement Algorithm and NLP Features

Abstract-Now a day’s social networking sites are the fastest medium which delivers news to user as compare to the news paper and television. There so many social networking sites are present and one of them is Twitter. Twitter allows large no. of users to share/post their views, ideas on any particular event. According to recent survey daily 340 million Tweets are sent on Twitter which is on a different topic and only 4% of posts on Twitter have relevant news data. It is not possible for any human to read the posts to get meaningful information related to specific event. There is one solution to this problem i.e. we have to apply Summarization technique on it. In this paper we have used an algorithm which uses frequency count technique along with this we have also used some NLP features to summarize event specified by user. This automatic summarization algorithm handles the numerous, short, dissimilar, and noisy nature of tweets. We believe our novel approach helps users as well as researchers.

Current Summary of the Practical Using of Optical Correlators

Optical Computing has long been a reportable as the solution of real - time high resolution data processing. Optical processing uses the fastest medium (light) to same calculations as serial electronic systems so process time of these calculations is shorter. The best results in data processing can be obtained by using hybrid, digital – optical, processors as a Optical Correlators which use speed of light (optical part) in cooperation with the electronic components, (digital part). Optical Correlator is optical device to compare two images or two – dimensional data in real time. There are two main types of Optical Correlators, Match Filter and Joint Transform Correlator. In this paper are described both types of correlators and there are shown examples of realized Optical Correlators. Optical Correlators use Optical Fourier Transform to produce transformed image from input image and then second Fourier Transform to obtained correlations in correlation plane. Optical Fourier Transform vs. Fast Fourier Transform process time comparison will be discussed. Main components of Optical Correlators will be presented. Optical Correlators thanks its fast process time and recent advances in liquid crystal technology become more commercially available. Potential applications of these optical processors will be also presented and discussed.

A hybrid intelligent system to improve predictive accuracy for cache prefetching

Cache being the fastest medium in memory hierarchy has a vital role to play for fully exploiting available resources, concealing latencies in IO operations, languishing the impact of these latencies and hence in improving system response time. Despite plenty of efforts made, caches alone cannot comprehend larger storage requirements without prefetching. Cache prefetching is speculatively fetching data to restrain all delays. However, effective prefetching requires a strong prediction mechanism to load relevant data with higher degree of accuracy. In order to ameliorate the predictive performance of cache prefetching, we applied the hybrid of two AI approaches named case based reasoning (CBR) and artificial neural networks (ANN). CBR maintains the past experience and ANN are used in adaptation phase of CBR instead of employing static rule base. The novelty of technique in this domain is valued due to hybrid of two approaches as well as usage of suffix tree in populating the CBR’s case base. Suffix trees provide rich data patterns for populating case base and greatly enhanced the overall performance. A number of evaluations from different aspects with varying parameters are presented (along with some findings) where the efficacy of our technique is affirmed with improved predictive accuracy and reduced level of associated costs.

Ground Truth from the Grassroots (Innovations Case Discussion: Map Kibera)

Initiative, have been properly lauded as new media projects. But their greater accomplishment lies in executing media projects in a way that is both modern and ancient: by working through community. The history of media development is littered with big, ambitious projects that are incubated in the United States and delivered “in a box” to developing countries, ready for assembly without consultation with the recipients and without adjustment to the realities on the ground. American graduate students return from the field with tales to tell: shipments of computers whose plugs didn’t fit the outlets, Internet connections that were instantly monopolized by teenage boys looking for porn, flash-ridden websites that take hours to download for users without broadband. The commercially driven tech culture in the United States is currently undergoing a reexamination by educators and social critics. Is more, faster media always better? How do we match the powerful new tools to the actual needs of society without losing sight of our goals? Our traditional framework for media technology deserves even closer scrutiny when extended to developing countries. Information is vital to life, as vital as food. Each culture uses the same nutrients but in many different forms, depending on the local culture and environment. The same is true of information: positive results can come in many forms, depending on the situation. In 2009, Erica Hagen and Mikel Maron launched their media project in Kibera, a sprawling, impoverished district of Nairobi, Kenya, that has become a regular

패션에서 유행을 따르게 되는 내적 에너지에 대한 연구 -Masochism을 중심으로-

The remarkable tendency shown in recent fashion can be the customer`s passiveness, not only their feeling desire for product but also needs for product seem to be made by mass media. So this condition can be thought as the currency of energy for being subjected. The public of fashion eagerly want the fashion style to be suggested for following it. The late Freudian, Erich Fromm said that the reason why individuals demand themselves to follow the masses` move could be explained as the hope against the fear of feeling not being from staying isolated and having no direction. Escaping from this fear, individuals ought to believe the necessity of participation in public. The fashion is willing to be defined as the united condition by individuals in the hope being consolidate in masses against being solitude. Nowadays, people can share many informations with internet, the fastest medium, which makes the individuals impatient not to be isolate, thinking other people must contact the information and should feel pressure of taking part in the currency. Even though the style is considered to be awkward for following it, it`s frequent exposure on mass media by celebrities wearing the style could soon make a fashion. This is able to show that many customers should incline to consider less about their style or taste, whereas lean to pursue after masses` authority. Recent consumers have propensity to avoid feeling concern about others` criticism, on the other side, they try to chase of the fashion as masses` choice for feeling peaceful. The reason why people recognize not to have clothing to wear in spite of a large wardrobe, it must reflect their needs promoted from outside influence of introducing for new styles.

High-resolution Imaging of Fault Zone Structures with Seismic Fault Zone Waves

Large fault zone (FZ) structures with damaged rocks and material discontinuity interfaces can generate several indicative wave propagation signals. High crack density may produce prominent scattering and non-linear effects. A preferred crack orientation can lead to shear wave splitting. A lithology contrast can produce FZ head waves that propagate along the material interface with the velocity and motion polarity of the faster medium. A coherent low velocity layer may generate FZ trapped waves. These signals can be used to obtain high resolution imaging of the subsurface structure of fault zones, and to track possible temporal evolution of FZ material properties. Several results have emerged from recent systematic analyses of such signals. The trapped waves are generated typically by ~100-m-widem-wide-widewide layers that extend only to ~3–4 km depth and are characterized by 30�–�0� velocity reduction and strong attenu�–�0� velocity reduction and strong attenu–�0� velocity reduction and strong attenu

A PARABOLIC EQUATION AND A PEARCEY-TYPE INTEGRAL FOR THE WAVE FIELD IN THE VICINITY OF THE CRITICAL RAY

The high-frequency wave field of a point source situated near the interface of two homogeneous media and placed in a faster medium is considered. A description of the wave field in a neighborhood of the critical ray in a slower medium is found by the parabolic-equation method. The result involves a Pearcey-type integral. The approach is not based on the Fourier method and can be generalized to inhomogeneous media with curved interfaces. Bibliography: 14 titles.

A geometric optics model for high‐frequency electromagnetic scattering from dielectric cylinders

The cylinder is a fundamental shape for (2‐D) geophysical modeling, and cylindrical objects (e.g., pipes) are a common target for ground penetrating radar. This paper presents physical and theoretical model responses for a cylinder which provide insight into responses that can be anticipated in field data. We calculate the exact expressions for the scattered field components of an obliquely incident plane wave over an infinitely long homogeneous dielectric cylinder and express them in the time domain. We project the field on a horizontal plane over the dielectric cylinder and interpret them for a large range of permittivity contrasts. The high‐frequency approximation presented in this paper includes the processes of specular reflection and critical refraction, which satisfy Snell’s law. Assuming the velocity of the surface waves is equal to the velocity of the fastest medium, and assuming their travel path is the shortest one possible, we derive a geometric optics model which is valid over a wide range of permittivities. We show that the critically refracted response can be separated and measured from the specular reflections in the received signal. The identification and isolation of these different responses of the bistatic measurements enable a characterization of the target’s properties, such as its size, orientation, and formation. We confirm our theoretical results by comparison with measurements using a physical model.

A Ray Description of All Wavefields Generated by a High-Frequency Point Source near an Interface

We consider the wavefield of a point source situated near an interface between two homogeneous acoustic half-spaces and placed in the faster medium. A high-frequency asymptotic description of all waves present is given by an elementary approach avoiding the explicit solution. The basic tool is the ray method based on real rays though some of the waves (e.g., the so-called P* wave) have complex eikonals. For a description of field in the vicinity of the limiting ray, a parabolic-equation approach is employed.

Cagniard-de Hoop path perturbations with applications to nongeometric wave arrivals

Nongeometric wave arrivals are often important in seismology and elastic wave studies related to the nondestructive evaluation of structures. In particular, tunnelling signals caused by significant differences in the material parameters, and wavespeeds at interfaces, generate large responses that may often be dominant. This is common in elastic wave propagation, for instance, when a source is close to the interface of a faster medium with a slower medium, the response in the slower medium is dominated by a signal that has tunnelled through the faster medium. Other instances of tunnelling occur when a compressional source is close to a free surface. In this case the compressional to shear wave conversion at the surface, and the mismatch between compressional and shear wavespeeds, leads to a sharp nongeometric shear wave arrival. Equally, thin high velocity layers demonstrate tunnelling effects that are perturbations of the response brought about by a source in a surrounding slower medium. In the above close refers to the viewpoint of an observer some distance away. In all of the instances there is a common feature, namely, each problem contains a ratio of length scales, x/h, with h either the source depth or layer thickness and x the observer distance; this ratio of length scales characterises the nongeometric responses. Typically, the nongeometric response arises when the current problem is a perturbation away from one where the associated arrival has a direct geometric interpretation. Such problems are ideally suited to analysis by the Cagniard-de Hoop technique. Each tunnelling response is identified as a perturbation away from an exact solution; this leads to highly accurate and relatively simple explicit asymptotic solutions. The perturbation scheme is demonstrated here via the solution of two problems: a compressional source beneath a fluid-solid interface and beneath a thin high velocity layer. The first problem has separate nongeometric responses due to both the material mismatch and the wave conversion at the interface. The thin high velocity layer perturbs the field generated by a compressional source in a slower surrounding medium. In both cases the nongeometric arrivals are analysed in detail.

Explant, medium and vessel aeration affect the incidence of hyperhydricity and recovery of normal plantlets in triploid watermelon

SummaryHyperhydricity or glassiness was a frequent problem during the micropropagation of triploid watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai) `Arka Manik' and this was influenced by level of BA, explant, medium and vessel aeration. High BA (5±10 mM) gave multiple shoots and led to high incidence and intensity of hyperhydricity while the use of low BA (1 mM) facilitated single-shoot growth with relatively low hyperhydricity. Hyperhydric cultures generally exhibited varying degrees of glassiness on subculturing or failed to grow at all. Shoot tip and upper nodal segments from lowly hyperhydric shoots on 1 mM BA medium often showed normal growth on subculturing while lower nodes tended to give glassy growth. Delaying subculturing thus contributed to hyperhydricity. Rugini olive (RO) basal medium showed better culture growth and less hyperhydricity than MS medium. Use of more gelling agent (phytagel 2.5 g vs. 3 g l­1 or agar 8 vs. 10 g l21), substitution of agar (10 g l­1) for phytagel (3 g l­1), incorporation of osmotic agents mannitol and sorbitol (500 mg l­1 each) in the medium or improving vessel aeration using caps with a 1.25 or 2.5 cm diameter opening covered with cotton bunk or cellulose nitrate filter (0.2 mm pore size) individually helped in reducing hyperhydricity to some extent. Provision for aeration was relatively superior to other approaches but more aeration (2.5 cm diameter) led to faster medium dehydration and growth limitation. Hyperhydricity/glassiness could be checked effectively with satisfactory growth by adopting a combination of low BA (1 mM), osmotic agents, agar gelling and vessel aeration (1.25 cm diameter cotton bunks) using RO or MS basal medium. Hyperhydric stock cultures could be salvaged or reverted to give normal growth by employing this approach coupled with better aeration (1.25 cm filter or 2.5 cm bunks) and selective use of shoot tip and upper nodal segments. Attempts to improve the propagation rate through multiple shoot induction using 5–10 mM BA after solving the hyperhydricity problem indicated that single-shoot growth using shoot tip and nodal cuttings in the presence of low BA (1 mM) was superior to the former, giving better net multiplication and normal plants.

Wrinkle‐like Weertman pulse at the interface between two blocks of foam rubber with different velocities

We verify the existence of self‐sustaining wrinkle‐like Weertman velocity pulses along a pre‐stressed interface between two dissimilar (ΔV = 60%) blocks of foam rubber. Properties of the observed velocity pulses are similar to the theoretical prediction of Weertman (1980), and the numerical calculations of Andrews and Ben‐Zion (1997). Particle displacement, in the direction perpendicular to the fault, is much larger in the slower medium than in the faster medium, resulting in a separation of the interface during the passage of the slip pulse. The rupture velocity is near the shear wave velocity in the slower material, and the direction of propagation is nearly always in the direction of the shear particle motion in the slower block. The pulse is self‐maintaining, that is, it does not die out from radiation damping, obtaining the necessary energy by releasing locally stored shear potential energy.

Propagation and loss in layered viscoelastic composites

The acoustic response of a source in an anisotropic viscoelastic medium has not only a directionally dependent speed of propagation, but also a directionally dependent rate of attenuation. The long wavelength properties of a layered composite comprised of two alternating constituent layers, both of which are isotropic, but with one elastic and the other viscoelastic (modeled as a ‘‘standard solid’’), are investigated. Such a structure behaves as a homogeneous transversely isotropic viscoelastic medium. The plane-wave phase slowness and quality factor as a function of direction are shown for three cases. The first two are (a) when the slower medium is lossy and (b) when the faster medium is lossy. In these cases, the curves for loss versus angle are highly directional, but the actual patterns depend dramatically upon the choice of (a) or (b). The third case examines the behavior when the velocities of the constituents are approximately the same, but the loss is such that which constituent is fast and which is slow is dependent on frequency.
