Tagging event image set using face identification

Events are organized by various Institutions round the year to encourage and enhance skills in academic and non-academic horizons. These events include seminar, workshop, cultural fest, product launch and the like. Event venues host digital devices to capture the proceedings. These devices generateenormous Video and Image data. These events are documented for auditing, evaluation and for future reference. Tagging these images based on the content and event context would facilitate and fasten the retrieval of these images. The tagged images could then be accessed based on a query. The objects of interest for tagging would include important personalities and key objects that describe a scene. Face detection based on training data set at large would aid in identifying persons.
Passive, transformerless coupling circuitry for narrow-band power-line communications

The field of power-line communications (PLC) has been maturing and therefore much research is aimed at making PLC technology cheaper. In this paper we investigate passive coupling circuits as an alternative to transformer-capacitor couplers, as the coupling transformer is a relatively expensive component. Various other sub-fields of PLC such as modulation and coding have received a lot of attention in recent years, whereas the sub-fields of coupling, filtering, impedance adaptation and protection have lagged behind. Most electronic circuits, especially filter circuits have been around for years and perhaps their design is sometimes viewed as exhausted. However, the nature of the power-line grid requires careful consideration, as sensitive modems are to be connected to the power-line network, via these coupling circuits. These couplers further have to withstand the strain of relatively large voltages and currents. Hence, sufficient time spent, designing and selecting coupling circuitry elements is essential to avoid unnecessary attenuation as well as possible damage to the more expensive communication circuitry.
A Fact of Life: Predictable Returns from an Equilibrium Model with Simple Fundamentals

We show that even when "fundamentals" are i.i. d. , a three-period OLG competitive model produces negatively autocorrelated expected returns, market risk premia, and prices. This negative autocorrelation arises out of market interactions between consumers that are ex-ante identical but differ by age. Conventional benchmark models do not exhibit any autocorrelation in such an i.i. d. world. The negative autocorrelation is pervasive in the model, and it remains regardless of the correlation structure of the "fundamentals". The generally agreed-upon properties of efficient markets depend heavily on conclusions from infinitely-lived representative consumer models. But these conclusions do not generalize to more complex trading environments.
Jam---designing a Java extension with mixins

In this paper we present Jam, an extension of the Java language supporting mixins, that is, parametric heir classes. A mixin declaration in Jam is similar to a Java heir class declaration, except that it does not extend a fixed parent class, but simply specifies the set of fields and methods a generic parent should provide. In this way, the same mixin can be instantiated on many parent classes, producing different heirs, thus avoiding code duplication and largely improving modularity and reuse. Moreover, as happens for classes and interfaces, mixin names are reference types, and all the classes obtained by instantiating the same mixin are considered subtypes of the corresponding type, and hence can be handled in a uniform way through the common interface. This possibility allows a programming style where different ingredients are "mixed" together in defining a class; this paradigm is somewhat similar to that based on multiple inheritance, but avoids its complication.The language has been designed with the main objective in mind to obtain, rather than a new theoretical language, a working and smooth extension of Java. That means, on the design side, that we have faced the challenging problem of integrating the Java overall principles and complex type system with this new notion; on the implementation side, it means that we have developed a Jam-to-Java translator which makes Jam sources executable on every Java Virtual Machine.
Shrinkage Optimized Directed Information using Pictorial Structures for Action Recognition

In this paper, we propose a novel action recognition framework. The method uses pictorial structures and shrinkage optimized directed information assessment (SODA) coupled with Markov Random Fields called SODA+MRF to model the directional temporal dependency and bidirectional spatial dependency. As a variant of mutual information, directional information captures the directional information flow and temporal structure of video sequences across frames. Meanwhile, within each frame, Markov random fields are utilized to model the spatial relations among different parts of a human body and the body parts of different people. The proposed SODA+MRF model is robust to view point transformations and detect complex interactions accurately. We compare the proposed method against several baseline methods to highlight the effectiveness of the SODA+MRF model. We demonstrate that our algorithm has superior action recognition performance on the UCF action recognition dataset, the Olympic sports dataset and the collective activity dataset over several state-of-the-art methods.
Modi ed Fourier Descriptors for ShapeRepresentation { A Practical

We propose a Modiied Fourier Descriptor and a new distance metric for describing and comparing closed planar curves. Our method accounts for the eeects of spatial discretization of shapes, an issue seldom mentioned, much less addressed in the literature. The motivating application is shape matching in a content based image retrieval system. The application requires a compact and reliable shape representation, and a feature distance measure which can be computed in real time. Experimental results suggest that our method is a feasible solution for on-line shape comparisons in such a system.

Ontology Maintenance : Quantifying the Conceptual Dynamics in Domain Ontologies

Most practically relevant domains include some degree of conceptual dynamics, i.e. new conceptual elements arise, and some old ones become irrelevant. In the products and services domain, for instance, corporations are continuously inventing new types of goods; and in physics, scientists may discover new types of particles or relations between them. This type of change imposes a substantial challenge on building up-to-date domain ontologies. While most research on ontology evolution has focused on technical solutions for managing such change that has already materialized in the ontology formalization, the order of magnitude of dynamics in real-world domains as the input variable to ontology engineering has not yet been studied. In this paper, we (1) provide a generic simulation model, based on a colored Petri-net, for measuring the conceptual dynamics and the resulting domain coverage of ontologies and (2) quantify the dynamics in three selected areas, i.e. for computer components, pharmaceuticals, and for methods, recipes, and procedures in the inorganic chemical technology sector. We can show that all three areas undergo a substantial conceptual dynamics and that this may lead to weak domain coverage in respective ontologies. Based on these findings, we (3) discuss approaches of how the engineering lag of building domain ontologies can be reduced.
The history of exergames: promotion of exercise and active living through body interaction

Exergames have become an important allied for many professionals of health field: physiotherapist, physical education teachers, physicians and many others. This new generation of video games has this special name because it combines exercise (with the prefix “exer”) and games. Also, exergames can be used as a resource to support the development of motor skills, promotion of an active living and healthy lifestyle, sports skills learning or simply as a tool to increase caloric expenditure. Indeed, the entertainment features presented as in any other digital game can hold a very important role to make the users more active during their leisure activities, instead of sedentary lifestyle, commonly perceived in the modern society. Within this innovation perspective for video games, this study aims to present the evolution of different interfaces, prototypes and patterns where exergames were designed with the focus on an Active Living development against the typical sedentary style of the former video games in the past. Through the conception of promotion of Exercise in this type of digital games, this paper will also show as results, how conceptions were invented since the decade of 1980 until the current era of exergames.

Bandwidth enhancement of coplanar waveguide fed disc monopole antenna for ultra-wideband communication applications

In this paper, a classically designed coplanar waveguide (CPW) fed disc monopole antenna is geometrically modified to obtain better performance in the frequency range 3.1–10.6 GHz. A tapered co-planar waveguide transmission line is adopted to improve the return loss performance in the required band. The complex radiation transfer function is simulated at three different directions to investigate the dispersive properties of the designed antenna. A prototype was fabricated and tested. The antenna was found to provide an ultra wide 10 dB return loss bandwidth with satisfactory omnidirectional radiation pattern.
Incremental Validity of Numerical Reasoning over Critical Thinking

This study was conducted to evaluate the incremental validity of numerical reasoning over critical thinking in predicting job performance and overall potential as measured by supervisors’ ratings. Results indicated significant incremental validity of numerical reasoning over and above critical thinking in the prediction of overall performance and overall potential. This paper presents the results of an examination of the incremental validity of numerical reasoning over critical thinking in the prediction of job performance and overall potential as measured by supervisors’ ratings. Professionals with responsibility for employee selection processes are faced with choosing from a broad array of assessment tools to help screen and select candidates. Making a correct choice has the potential to maximize the effectiveness of selection decisions while minimizing time and costs involved. Conversely, choosing the wrong set of assessment tools can lead to poor hiring decisions and wasted resources. Due to the relevance and importance of critical thinking across a wide range of jobs (O*Net OnLine, 2005), the use of tools and methods for evaluating critical thinking of job applicants has been a popular practice among HR practitioners, I/O Psychologists, and other professionals working in the area of employment selection.

Life on the Edge: A sociophonological analysis of diphthong variation and change

This paper presents an innovative socio-phonological analysis of dialect variation and change. The analysis uses sociolinguistic data regarding the diphthongs |au|, |ai| and |ei| in Mersea Island English, a variety of British English. The trajectory of change shown by the data, as well as certain aspects of contextual variation (namely Canadian Raising) will provide the basis for outlining a three-tiered model that represents both internal (linguistic) and external (sociolinguistic) factors on variation and, ultimately, change . The model draws on the mechanics of both Dispersion Theory and Optimality Theory. This allows for system optimisation in the underlying phonology to be represented alongside optimal candidate selections after phonetic contextual information becomes available. The outputs from these levels, together with other possible surface variants, are then shown to have sociolinguistic associations that influence which form is ultimately selected as the surface form.
Advancement to the Real Option Models in Valuing R&D

I. INTRODUCTION Merton (1987) asserted the importance of information cost and documented that an investor shall demand higher stock return if higher information cost is expensed. Following the context of Merton, Bellalah (1999a, 2003b) incorporated the information cost factor in valuing both options and RD its value could also be vanished overnight because of any unexpected evolution. These facts imply some other exogenous factors which influence the RD though this idea was not taken eventually. We are going to observe the individual effect of information costs; we are also going to actualize Bellalah's proposal to see what the real level of information cost could be and. To sum up, the existing ROM in valuing RD we are trying to reduce the mentioned inappropriateness through both statistical and mathematical means. II. RE-MODELING The factors of exponential decay [theta] and Poisson event [xi] are going to be considered. [mu] means the required rate of return which is the sum of expected capital gain [alpha] and dividend [delta]. While exponential decay and Poisson event are jointly considered, the project value can be: [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]. (1) The R&D project value can be deemed the function of product price 'P'. P follows the mean reverting process dPdt + [alpha]PdZ - [pi]P[xi]dt, [phi] represents the loss rate of the sudden death, [xi] represents the probability of sudden death. The revenue of an investment can be expressed as u = [alpha] + [delta], [alpha] is drift term, [delta] represents dividend yield, [mu] is the risk adjusted expected rate of return which equals to the risk free rate r under the premise of arbitrage free. The expected present value of cash flow will become: [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII], which is the integral base of the value of entire investment V. If the stochastic process of exponential decay is further considered, its p.d. f. function will be incorporated as the (1) showed. Through (1), a spiky event like [theta] and [xi] can be smoothened as an additional discount factor in the denominator. According to ROM, an R&D project value V can be seen as a combination of investment I and option value F therefore V(P)=I+F(P). We may utilize a portfolio [PHI] = F(P) - nP as to long one unit of option and to short n units output with price P and let its payoff be: r[F - nP]dt = dF - ndP - n[delta]Pdt (2) From (2) we can derive a corresponding Bellman equation: (1/2)[[sigma]. sup.2][P.sup.2][F.sub. PP] + (r - [delta])[PF.sub. p] - rF = 0 (3) In (3), we set n = F'(P) to eliminate the disturbance term dz. (3) is a Partial Differential Equation (PDE) and we can solve F by either analytical, if it has a close form solution, or numerical way. …
Hybrid storage architecture for video on demand server

Large-scale video on demand (VOD) services use hard disk drives (HDDs) to store large video files. However, VOD performance is limited by the relatively low bandwidth access and high HDD latency access, which increase dramatically when a VOD server receives a large number of simultaneous requests. By contrast, flash-based solid-state drives (SSDs) are an attractive alternative because these ensure fast access to an intensive reading system such as VOD. A flash-based SSD only stores popular videos to provide fast access for read-intensive workloads. Unfortunately, replacing the entire HDD with SSD is costly because of its high cost per gigabyte. Therefore, hybrid HDD storage and the small capacity of a flash-based SSD can provide high but cost-effective performance in relation to the storage subsystem of a VOD server. The main goal is to improve the performance of the VOD server by maximizing the number of concurrent user requests and minimizing startup latency in a cost-effective way. Experimental results show that the hybrid HDD storage with flash-based SSD provides better performance than the HDD-based system because it can reduce the average response time for a large-scale VOD storage server by approximately 52.44%.
Ju n 20 05 Conifold transitions and Mori theory

We show there is a symplectic conifold transition of a projective 3-fold which is not deformation equivalent to any Kähler manifold. The key ingredient is Mori’s classification of extremal rays on smooth projective 3-folds. It follows that there is a (nullhomologous) Lagrangian sphere in a projective variety which is not the vanishing cycle of any Kähler degeneration, answering a question of Donaldson.
Linguistic Linked Data in Chinese: The Case of Chinese Wordnet

The present study describes recent developments of Chinese Wordnet, which has been reformatted using the lemon model and published as part of the Linguistic Linked Open Data Cloud. While lemon suffices for modeling most of the structures in Chinese Wordnet at the lexical level, the model does not allow for finergrained distinction of a word sense, or meaning facets, a linguistic feature also attended to in Chinese Wordnet. As for the representation of synsets, we use the WordNet RDF ontology for integration’s sake. Also, we use another ontology proposed by the Global WordNet Association to show how Chinese Wordnet as Linked Data can be integrated into the Global WordNet Grid.
Skyrmions in a doped antiferromagnet.

Magnetization and magnetoresistance have been measured in insulating antiferromagnetic La2Cu0.97Li0. 03O4 over a wide range of temperatures, magnetic fields, and field orientations. The magnetoresistance step associated with a weak ferromagnetic transition exhibits a striking nonmonotonic temperature dependence, consistent with the presence of Skyrmions.
