Some Cautions on the Use of Panel Methods for Integrated Series of Macroeconomic Data

We show how the use of panel data methods such as those proposed in single equations by Kao and Pedroni or in systems by Larsson and Lyhagen to investigate economic hypotheses such as purchading power pariety or the term structure of interest rates may be affected by the existence of cross-unit cointegrating relations.
A New Algorithm for Computing Grobner Bases

Polynomial systems are ubiquitous in Mathematics, Sciences and En- gineerings, and Grobner basis theory is one of the most powerful tools for solving polynomial systems. Buchberger introduced in 1965 the first algorithm for computing Grobner bases and it has been imple- mented in most computer algebra systems (e.g. Maple, Mathematica, Magma, etc). Faugere presented two new algorithms: F4 (1999) and F5 (2002), with the latter being the faster algorithm known. Last semester, Frank Volny presented a new incremental algorithm (G2V) that is two to ten times faster than F5. In this talk, I shall present a generalization of G2V that matches Buchberger's algorithm in sim- plicity yet is several times faster than G2V. The talk will be accessible to a general audience.

Comments on "Critical Study on the Absorbing Phase Transition in a Four-State Predator-Prey Model in One Dimension"

In a recent article [arXiv:1108.5127] Park has shown that the four-state predatorprey model studied earlier in J. Stat. Mech, L05001 (2011) belongs to Directed Percolation (DP) universality class. It was claimed that predator density is not a reasonable order parameter, as there are many absorbing states; a suitably chosen order parameter shows DP critical behaviour. In this article, we argue that the configuration that does not have any predator is the only dynamically accessible absorbing configuration, and the predator density too settles to DP critical exponents after a long transient.
Plasma-Wall Interaction in Magnetically Confined Fusion Plasmas

Abstract The control of wall loads in fusion devices, in particular with respect to the life time limitations of wall components due to material erosion and migration, will be decisive for the realisation of a fusion power plant operating in steady state, while in a pulsed experiment like ITER the primary goal for plasma-wall interaction is the achievement of a high availability. The article describes the grand challenges of plasma-wall interaction research along the needs for ITER and the strategies of ongoing research for further optimization of the design. Addressed are questions related to material problems, erosion- and transport processes, tritium retention in deposited layers and transient heat loads.

Efficient Multiplication in GF(pk) for Elliptic Curve Cryptography

We present a new multiplication algorithm for the implementation of elliptic curve cryptography (ECC) over the finite extension fields GF(pk) where p is a prime number greater than 2k. In the context of ECC we can assume that p is a 7-to-10-bit number, and easily find values for k which satisfy: p > 2k, and for security reasons log2 ? k ? 160. All the computations are performed within an alternate polynomial representation of the field elements which is directly obtained from the inputs. No conversion step is needed. We describe our algorithm in terms of matrix operations and point out some properties of the matrices that can be used to improve the design. The proposed algorithm is highly parallelizable and seems well adapted to hardware implementation of elliptic curve cryptosystems.
High Q LTCC-based passive library for wireless system-on-package (SOP) module development

In this paper, we present the development and full characterization and modeling of a multilayer ceramic-based system-on-package component library. Compact high-Q three-dimensional inductor and capacitor topologies have been chosen and incorporated. A measured inductor Q factor as high as 100 and self-resonant frequency as high as 8 GHz have been demonstrated. The new vertically interdigitated capacitor topology occupies nearly an order of magnitude less of real estate while demonstrating comparable performance to the conventional topology. The low-temperature co-fired ceramic (LTCC) library has been incorporated into a 1.9-GHz CMOS power-amplifier design exhibiting a measured 17-dB gain, 26-dBm output power, and 48% power added efficiency. This power-amplifier module with fully integrated LTCC passives demonstrates a superior performance to those with full and partial on-chip passive integration.

Poisson brackets for orthogonal polynomials on the unit circle

The recently discovered connection of orthogonal polynomials on the unit circle (OPUC) to the defocusing Ablowitz-Ladik integrable system involves the definition of a Poisson structure on the space of Verblunsky coefficients. In this paper, we compute the complete set of Poisson brackets for the monic orthogonal and the orthonormal polynomials on the unit circle, as well as for the second kind polynomials and the Wall polynomials, thus answering a question posed by Cantero and Simon, [CanSim].
A mean field approximation approach to blind source separation with L p priors

In this paper we address the problem of Bayesian blind source separation with generalized p-Gaussian priors for the sources (also known as L p priors). These kind of priors are useful when modeling sparse sources (spiky signals, wavelet coefficients …) The corresponding posterior laws are non linear and either maximum a posteriori (MAP) or posterior mean estimates are computationally difficult to obtain especially for values of p approaching unity. In this work, we consider a mean field approximation approach to approximate the joint posterior distribution by a separable distribution on its parameters: unobservable sources, mixing matrix, noise covariance matrix and hyper-parameters (source scale parameters). This approach requires, however, marginalisation of the log-likelihood with respect to these parameters. With appropriate prior assignments, this can be done explicitly for the mixing matrix, the noise covariance matrix and the scale parameters. For the sources, we consider a Kullback distance based approximation in order to obtain estimates of the first two moments of the sources. Simulation results are presented to support the proposed approach.
Effects of physical processes of H2O on the general circulation of the atmosphere; part II

In Part 1 (Miyoshi and Morita, 1993), we investigated how the general circulation of the atmosphere was affected by all the physical processes of H 2 O. In this study, we divide all the physical processes of H 2 O into the radiative process of H 2 O and the hydrological cycle, and investigate the effect of both of the processes separately by a series of GCM experiments. Results are as follows. The north-to-south temperature gradient and the zonal wind distribution below 5 km height is strongly affected by the radiative process of H 2 O. The strength of the meridional circulation, the magnitude of the poleward energy transport, the magnitude of the sensible and latent heat fluxes and the magnitude of the diabatic heating rate in the atmosphere also depend on the radiative process of H 2 O. Thus, the differences of the general circulation between with and without all the physical processes of H 2 O is mostly caused by the radiative process of H 2 O. The zonal wind distributions above 5 km height, on the other hand, are affected by not only the radiative process of H 2 O but also by the hydrological cycle. Numerical experiments using a vertically one-dimensional radiative-convective equilibrium model are performed. By comparing the radiative-convective equilibrium temperature with the temperature in the GCM, the relation between the poleward heat transport by the dynamics and the physical processes of H 2 O is also examined. In the experiments without the radiative process of H 2 O, the temperature near the surface in the GCM is almost the same as the radiative-convective temperature. At low latitudes, the temperature difference between the GCM and the radiative-convective model is larger in the experiments with the radiative process of H 2 O than in the experiments without the radiative process of H 2 O.
Automatic software test data generation based on DWSPSO

An approach for generating structural test data based on modified simple particle swarm optimization using dynamically changing inertia weight(DWSPSO) is proposed.The algorithm discards the particle velocity and tracks the state of particle swarm by observing the overall changes in the fitness of all particles in the swarm.According to the changes of the fitness,updated the inertia weight of each particle after each iteration to achieved a self-adaptive adjustment of global search ability and local search capabilities.The result of experiment shows that the improved algorithm is better than the basic PSO and LDWPSO[1],when used to automated data generation.
MATCHING RULES AND SUBSTITUTION TILINGS

A substitution tiling is a certain globally defined hierarchical structure in a geometric space; we show that for any substitution tiling in Ed, d > 1, subject to relatively mild conditions, one can construct local rules that force the desired global structure to emerge. As an immediate corollary, infinite collections of forced aperiodic tilings are constructed. The theorem covers all known examples of hierarchical aperiodic tilings. On the left in Figure 1, L-shaped tiles are repeatedly "inflated and sub-divided. " (We define our terms more precisely in Section 1.) As this process is iterated, larger and larger regions of the plane are tiled with L-tiles hierarchically arranged into larger and larger images of inflated and subdivided L-tiles, as at right in Figure 1 (the thicker lines have been added to emphasize the hierarchy). We can then define a global structure-the "substitution tiling" induced by the inflation and division of the tiles. But L-tiles can tile the plane in myriad ways. Is there a set of local conditions-"matching rules"-that, if satisfied everywhere, force the hierarchical structure of the substitution tiling to emerge? One can show that no such rules exist for unmarked L-tiles. However, we can find a set of marked L-tiles, and matching rules that force the the original hierarchical structure to emerge. For example, in Figure 2, we tile with the two marked tiles at upper left, and require that the colors "black", "grey" and "white" match along the

Performance–energy trade-off in controllable servers with set-up delays

We develop queueing models for a single node in a server farm and analytically study the impact of set-up delay on the performance–energy trade-off. The objective is to compare how an optimized static speed scaling scheme performs against two (gated and linear) optimized dynamic speed scaling schemes, where the processor can be switched off when it is idle but the penalty is the set-up delay (time to wake up the processor from the off state and the energy consumed during the set-up delay). In the gated scheme, the processor speed is zero when the server is idle and constant otherwise, and in the linear scheme the processing speed scales linearly with the number of jobs. In our analysis, the set-up delay and the job sizes can have general distributions, except in the linear scheme. Our results demonstrate that the set-up delay has a considerable impact on the optimal trade-off. The linear scheme is always better than the gated scheme and, when the set-up delays are long, even the static scheme can be better. Also, we observe that greater variability in the job size distribution leads to higher gains. In practice, however, the trade-off is affected highly by the parameters.
Identification of Chinese Names Based on Statistics

Identification of Chinese names is one of important techniques to improve the accuracy of automatic word segmentation. This paper proposes an effective model based on statistics to identify Chinese names. It establishes rewards punishment mechanism and supervised learning mechanism, and presents the reliability for the word segmentation in the model. The experiments show that the precision and recall rate respectively reach 95.97% and 95.52% by close test, while the precision and recall rate are 92.37% and 88.62% by open test.
Exchange rate volatility and global shocks in Russia: an application of GARCH and APARCH models

This study examines global shocks and the volatility of the Russian rubble/United States dollar exchange rate using the symmetric Generalized Autoregressive Conditional Heteroscedasticity (GARCH), and Asymmetric Power Autoregressive Conditional Heteroscedasticity (APARCH) models. The GARCH and APARCH are employed under normal (Normal Gaussian) and non-normal (Student’s t and Generalized Error) distributions. Using monthly exchange rate data covering the period January 1994- December 2013, the study finds that the symmetric (GARCH) model has the best fit under the non-normal distribution, which improves the overall estimation for measuring conditional variance. Converse-ly, the APARCH model does not show asymmetric response in exchange rate volatility and global shocks, resulting in no presence of leverage effect. The GARCH model under the Student’s t distribution produces better fit for estimating exchange rate volatility and global shocks in Russia compared to the APARCH model.

evolution of case grammar

There are few linguistic phenomena that have seduced linguists so skillfully as grammatical case has done. Ever since Panini (4th Century BC), case has claimed a central role in linguistic theory and continues to do so today. However, despite centuries worth of research, case has yet to reveal its most important secrets. This book offers breakthrough explanations for the understanding of case through agent-based experiments in cultural language evolution. The experiments demonstrate that case systems may emerge because they have a selective advantage for communication: they reduce the cognitive effort that listeners need for semantic interpretation, while at the same time limiting the cognitive resources required for doing so.
An exploration of artefacts of remote desktop applications on Windows

Remote Desktop Applications (RDA) such as Virtual Network Computing (VNC), Cisco WebEx, GoToMeeting and LogMeIn have been adapted and utilised recently. This is because they facilitate tier-one support to configure computers, networks and solve application-related issues from a remote location. The direct benefit from the use of these applications, is the time (and therefore cost) saving for organisations. Unfortunately, “remoting” technology can also be used by criminals to perform illegal activities, hence remote applications are of key interest to law agencies and forensic investigators. The research outlined in this paper aims to identify any artefacts left behind by common remote applications and technologies used by many firms. These artefacts can be vital to government law enforcement agencies and forensic investigators, as they could be used as evidence in cyber-crime investigations. This research will focus on RealVNC, TightVNC, Cisco WebEx, GoToMeeting and LogMeIn applications. The findings from the research shows some artefacts left behind by the applications, which can be used by forensics investigators or law enforcement for possible evidence.
Estimation of Initial Position Using Line Segment Matching in Maps

While navigating in a typical traffic scene, with a drastic drift or sudden jump in its Global Positioning System (GPS) position, the localization based on such an initial position is unable to extract precise overlapping data from the prior map in order to match the current data, thus rendering the localization as unfeasible. In this paper, we first propose a new method to estimate an initial position by matching the infrared reflectivity maps. The maps consist of a highly precise prior map, built with the offline simultaneous localization and mapping (SLAM) technique, and a smooth current map, built with the integral over velocities. Considering the attributes of the maps, we first propose to exploit the stable, rich line segments to match the lidar maps. To evaluate the consistency of the candidate line pairs in both maps, we propose to adopt the local appearance, pairwise geometric attribute and structural likelihood to construct an affinity graph, as well as employ a spectral algorithm to solve the graph efficiently. The initial position is obtained according to the relationship between the vehicle's current position and matched lines. Experiments on the campus with a GPS error of dozens of metres show that our algorithm can provide an accurate initial value with average longitudinal and lateral errors being 1.68m and 1.04m, respectively.
Video looping of human cyclic motion

Video Looping of Human Cyclic Motion. (May 2004) Hye Mee Choi, B.S., Korean Sahmyook University; M.F. A. , Hongik University Chair of Advisory Committee: Dr. Ergun Akleman In this thesis, a system called Video Looping is developed to analyze human cyclic motions. Video Looping allows users to extract human cyclic motion from a given video sequence. This system analyzes similarities from a large amount of live footage to find the point of smooth transition. The final cyclic loop is created using only a few output images. Video Looping is useful not only to learn and understand human movements, but also to apply the cyclic loop to various artistic applications. To provide practical animation references, the output images are presented as photo plate sequences to visualize human cyclic motion similar to Eadweard Muybridge’s image sequences. The final output images can be used to create experimental projects such as composited multiple video loops or small size of web animations. Furthermore, they can be imported into animation packages, and animators can create keyframe animations by tracing them in 3D software.
