Morphological Texture Manipulation for The Evaluation of Human Visual Sensibility

Since the surface texture of materials often affects human visual impressions as much as or more than the design, shape, or color properties, texture characteristics have been studied as features of object identification. We have been investigating the effect of texture on visual impression and objective identification using black fabrics that do not exhibit any effects of color. Our studies showed that visual impressions of texture correspond to complex micro-components and global structures of image features of those textures. Our results also showed that some important elements influence human visual impressions and identification of textures. Because of a variety of fibrous structures, it is not easy to provide a systematic analysis of clothing materials. Nevertheless, developing the method and collecting data on these elements and their effects using these image features will be important. To make this research applicable for wider use, we have been studying precisely what it is about an arbitrary texture that influences human visual impressions and sensibility. As a new step, in this paper, a texture is altered and transformed using the parameter estimation method of texture based on mathematical morphology, which is often used for extracting image components that are useful for representation and description. A texture is decomposed into a primitive and grain arrangement which correspond to local and global characteristics, respectively. Different textures are created by modifying the primitive and the arrangement to investigate the effects of modifications of local and global features. The relationship between the parameters and visual impressions of the modified textures were evaluated. This study shows that influence of both local and global structures of the texture along with their combinations and mutual interactions are important for identification of human visual impression.
Comparing constructicons: A usage-based analysis of the causative construction with doen in Netherlandic and Belgian Dutch

In the constructionist view, the grammar of a language is represented by constructions organized in taxonomic networks. This paper addresses the question of how one should account for the differences and similarities in the organization of such networks in different varieties of a language. In particular, a corpus-driven quantitative methodology is developed that can provide evidence for modelling the relevant constructional networks. The method is based on hierarchical cluster analysis applied to multivariable data, and several statistical criteria of cluster stability. These points are demonstrated by means of a corpus study of the Netherlandic and Belgian variants of the Dutch causative construction with doen “do”. The paper describes the national differences in the structure of the constructicon and interprets them from a usage-based historical perspective.
Experiments with computer-controlled displays in second-language learning

Three displays were evaluated for their effectiveness in overcoming pronunciation problems that typically confront Spanish speakers attempting to learn English. One display shows tongue location and trajectory during vowels; another similar display isolates the vowels in multisyllabic words that should be reduced; the third display shows the amount of aspiration of initial consonants and the time lapse before voicing of the succeeding vowel. Other displays are being developed for teaching a tone language to English speakers.
Review: GaN growth by ammonia based methods – density functional theory study

Recent results in Density Functional Theory (DFT) simulations of ammonia‐based growth of gallium nitride on GaN (0001) are reviewed. These simulations are important to the following GaN growth methods that use ammonia as active nitrogen source: ammonothermal, MOVPE, HVPE and also ammonia‐source MBE. In the simulations of GaN growth, the two main approaches were discussed: (1) equilibrium, based on chemical potentials of the components, and (2) dynamic, based on consideration of atomistic processes on the surface. These two approaches are unified by the kinetic procedure of determination of the chemical potential levels for nitrogen and hydrogen as a function of partial pressure of ammonia. Here the DFT modeling of GaN(0001) surface employing the technique of the simulation of subsurface electric field is described and employed. The results of DFT modeling include the ammonia and molecular hydrogen adsorption on GaN(0001) surface that allows to determine some basic features of ammonia‐based growth of GaN.

TOOLS AND TECHNIQUES IN SIMULATION OF HIGHLY COMPLEX, DYNAMIC SYSTEMS

This paper will tell us some considerations on solution tools for highly complex problems usually unsolvable by classic exact tools. We are all surrounded by such complex problems even in our every-day life. Usually we should not deal with them in the merit, as we can manage them by intuitive steps and reactions. Other models cannot be handled so easily. There is a great need for qualitative simulating tools and techniques. A rural development system, product development processes, a university management or the solid waste system in New York cannot be investigated without sophisticated simulation tools. The subject of this paper is to develop tools for models, which consist of several parallel processes. Tools and techniques, that will be introduced in the following, have the goal to help the analysis of dynamic systems. Researchers need interactivity to see the behaviour of a system. Another issue is reliability. Double run estimations present a solution for this problem. All these features and more others are included in our simulation tool. The simplicity of experimenting has been utilized and new results have been reached in the models mentioned. Further steps have been taken to develop a well-usable interface.
Spatial decorrelation due to topography in the interferometric SAR coherence imagery

A modified spatial decorrelation function for SAR interferometry is derived as a function of both the baseline and the terrain slope. This function has been used to explain the total decorrelation phenomenon on slopes directly facing radar illumination, which is an obstacle for a side-looking radar interferometry. A zone of critical incidence angle (or, critical terrain slope) can be determined using the function. Within this zone, radar signals from two acquisitions separated by a baseline will become completely decorrelated regardless of any other conditions. The width of the critical incidence angle zone increases with the increase of baseline separation. An analytic method, ratio coherence imagery, is then introduced to identify the topographic total decorrelation of the radar-facing slope from other temporal decorrelation features and to analyse the nature of different coherence features effectively. An application of the new methodology in the east of Sahara desert, Algeria is presented.
The statistical analysis of series of events

Observations in the form of point events occurring in a continuum, space or time, arise in many fields of study. In writing this monograph on statistical techniques for dealing with such data, we have three objectives. First, we have tried to give a simple description, with numerical examples, of the main methods that have been proposed. We hope that by concentrating on the examples the applied statistician with a limited inclination for theory will find something of practical value in the monograph. Second, the monograph is intended as a survey, necessarily incomplete, of some of the problems in theoretical statistics that stem from this sort of data. A number of specialized subjects have, however, been dealt with only briefly, the main emphasis being placed on the problem of examining the structure of a series of events. Finally, we hope that the monograph will be of use to teachers and students of statistics, as illustrating applications of a range of tech niques in theoretical statistics. We are extremely grateful to the International Business Machines Corporation for providing programming assistance and a large amount of computer time. We wish to thank particularly Mr A. "
A new joint transmit and receive optimization scheme for OFDM-based MIMO systems

To approach the potential MIMO capacity while optimizing the system performance, a joint Tx/Rx MMSE design has been proposed. It is an optimal linear scheme for spatial multiplexing MIMO systems assuming a fixed number of parallel data streams as well as fixed modulation and coding across these streams. The use of OFDM enables a low-complexity implementation of this design for frequency-selective MIMO channels. In such a MIMO/OFDM set-up, the state-of-the-art joint Tx/Rx MMSE approach would arbitrarily choose and fix the number of space-frequency data streams p to be transmitted, which may lead to an inefficient power allocation strategy and a non-minimum bit-error-rate (BER). Therefore, in this paper, we propose to relax the fixed number of streams p constraint and address the issue of optimizing p for this design under fixed average total transmit power P/sub T/ and fixed global rate R constraints. In typical frequency-selective indoor channels, the resulting space-frequency optimized joint Tx/Rx MMSE design is shown to lead to a 10 dB SNR gain over the full spatial multiplexing conventional joint Tx/Rx MMSE design for a (2,2) MIMO/OFDM set-up at BER = 10/sup -3/ and an average spectral efficiency of 4 bits/carrier. Such a dramatic improvement is due to the better exploitation of the system's frequency and space diversity enabled by the proposed optimization.
Visualizing Japanese Co-Authorship Data

This paper reports a bibliometric analysis of evolving co-author networks. Using 5,009 articles covering the years 1993 to 2005 from Transactions D. (Information Systems) of the Institute of Electronics Information and Communication Engineers (IEICE), we attempt to compare the network characteristics for each year, the co-author network characteristics for the entire time span, and the four major components of the entire data set. Finally, we analyze each of these in contrast to extant co-authorship network data and find that the pattern of co-authorship within Information Systems does not change significantly over this time period.

We provided high image quality having an average peak signal‐to‐noise ratio (PSNR) > 45dB. We integrate a timing controller and SDRAM to a single package.
Image Classification Using Bag of Visual Words and Visual Saliency Model

As social multimedia sites are getting popular such as Flickr and Facebook, the amount of image information has been increasing very fast. So there have been many studies for accurate social image retrieval. Some of them were web image classification using semantic relations of image tags and BoVW(Bag of Visual Words). In this paper, we propose a method to detect salient region in images using GBVS(Graph Based Visual Saliency) model which can eliminate less important region like a background. First, We construct BoVW based on SIFT algorithm from the database of the preliminary retrieved images with semantically related tags. Second, detect salient region in test images using GBVS model. The result of image classification showed higher accuracy than the previous research. Therefore we expect that our method can classify a variety of images more accurately
A Performance Model of Highly Available Multicomputer Systems

Abstract Multicomputers are distributed memory systems in which independent computers are connected with each other by a network. Multicomputers are widely used in business and scientific applications. Due to their flexibility, scalability, and cost performance, multicomputer systems are considered preferable to multiprocessor systems. They are also gaining attraction in the area of Internet-based computing, in which delays or interruptions in client—server interactions may be equally costly to service providers and customers. Multicomputer systems attributed with high available (HA) solutions may be used to with stand service unavailability due to the web servers' failures. In this paper we investigate a Markov model-based approach to estimate the availability of multicomputer systems with and without HA. The availability is computed as a function of server failure rate and the number of surviving servers. This model can estimate the number of nodes needed for a required availability measure.
Efficient design of gallium arsenide Muller-C element

A Muller-C element is a fundamental building block of a handshake path in self-timed digital circuits. It is a basic event driven logic (EDL) gate, implementing the AND function for events. The authors present a new, improved design of the Muller-C element using GaAs MESFET technology. A static Muller-C gate is implemented that incorporates modifications of newly introduced, GaAs pseudodynamic latched logic family (PDLL) primitives. The circuit is characterised by very high speed and low power dissipation.
Null-field computations of radar cross sections of composite objects

The application of the null-field approach to radar cross section computations for composite objects is reviewed. The scattering problem is solved by means of a determination of the total transition matrix for the composite scatterer. It is noted that alternative approaches are usually available, which lead to different expressions for the transition matrix and which have different numerical characteristics. Results from the numerical implementation of these formulas are illustrated in a number of examples, and it is found that useful convergence can be achieved for a frequency interval that often extends into the resonance region. A number of ways of checking the quality of the results are also indicated. >
Recent developments in the design and synthesis of benzylpyridinium salts: Mimicking donepezil hydrochloride in the treatment of Alzheimer’s disease

Background: Alzheimer’s disease (AD) is an advanced and irreversible degenerative disease of the brain, recognized as the key reason for dementia among elderly people. The disease is related to the reduced level of acetylcholine (ACh) in the brain that interferes with memory, learning, emotional, and behavior responses. Deficits in cholinergic neurotransmission are responsible for the creation and progression of numerous neurochemical and neurological illnesses such as AD. Aim: Herein, focusing on the fact that benzylpyridinium salts mimic the structure of donepezil hydrochlorideas a FDA-approved drug in the treatment of AD, their synthetic approaches and inhibitory activity against cholinesterases (ChEs) were discussed. Also, molecular docking results and structure–activity relationship (SAR) as the most significant concept in drug design and development were considered to introduce potential lead compounds. Key scientific concepts: AChE plays a chief role in the end of nerve impulse transmission at the cholinergic synapses. In this respect, the inhibition of AChE has been recognized as a key factor in the treatment of AD, Parkinson’s disease, senile dementia, myasthenia gravis, and ataxia. A few drugs such as donepezil hydrochloride are prescribed for the improvement of cognitive dysfunction and memory loss caused by AD. Donepezil hydrochloride is a piperidine-containing compound, identified as a well-known member of the second generation of AChE inhibitors. It was established to treat AD when it was assumed that the disease is associated with a central cholinergic loss in the early 1980s. In this review, synthesis and anti-ChE activity of a library of benzylpyridinium salts were reported and discussed based on SAR studies looking for the most potent substituents and moieties, which are responsible for inducing the desired activity even more potent than donepezil. It was found that linking heterocyclic moieties to the benzylpyridinium salts leads to the potent ChE inhibitors. In this respect, this review focused on the recent reports on benzylpyridinium salts and addressed the structural features and SARs to get an in-depth understanding of the potential of this biologically improved scaffold in the drug discovery of AD.

The multichannel speech enhancement technology is studied in this paper, aiming at the Voice Interactive. The simulated results show the effectiveness and superiority of the improved algorithm proposed in the paper.
A Joint Coding Method Based on Rateless Coding and Channel Coding at Network Layer

Decoding overhead is a standard for measuring whether rateless coding is good or not. The product-code coding of Shifted RSD, a communication transmission scheme, is based on the joint decoding of rateless coding and channel coding at the network layer of feedback information, was proposed in this study in order to reduce the overhead of decoding in rateless coding in the wireless communication. This method combines rateless coding and channel coding at the network layer to decode, which results in multiple packets instead of one recovered by iterative decoding every time during decoding. The decoding is accomplished until all packets are decoded, and the original information of source is recovered. The decoding overhead used for recovering the original information can be reduced due to the increase in the number of packets recovered at a time. Experimental results show that the use of this method combining channel coding with rateless coding to decode requires less decoding overhead than using LT code or RSD code with feedback for decoding, thus improving the decoding capability of the receiving end.
Gas exchange rates in the tidal Hudson river using a dual tracer technique

Gas exchange rates have been determined in the tidal Hudson River by injecting 2 inert gases, 3 He and sulfur hexafluoride (SF 6 ) and monitoring their decline with time. Their distributions along the main axis of the river were approximately gaussian and maximum concentrations of excess 3 He and SF 6 observed during each transect decreased from about 6500 × 10 -16 cm 3 STP g -1 and 250 ppt (part per trillion by volume), respectively, to values close to atmospheric equilibrium concentrations over a period of 16 days. Throughout the experiment, vertical gradients in tracer concentration were observed. After 3 days of mixing, tracer concentrations in bottom samples were 0–19% greater than in surface samples. Gas transfer velocities were calculated from the temporal change in the depth averaged excess 3 He/SF 6 ratio from stations having maximum tracer concentrations. They ranged from 1.5 to 9.0 cm h -1 and correlated well with mean wind speed. DOI: 10.1034/j.1600-0889.1994. t01-2-00003.x

Complementing Self-Serve Technology with Service Relationships: The Customer Perspective

The adoption of self-service technology (SST) by customers is arguably the hallmark of a successful dot-com venture. * The more customers go online to fulfill their service needs themselves, the more scalable and cost-effective the business model. However, in the business-to-business environment, embedded relationships between customers and providers (e.g., sales representatives) have traditionally been key in generating repeat business and financial success (Anderson et al., 1994). This raises questions about the impact of using SSTs to complement service relationships, a strategy that an increasing number of firms is employing. This research relies on qualitative research methods, particularly interviews, to explore what factors determine the mode of service interaction (SST, representative, or a combination of the two) customers choose. Conceptualizing relationship-SST complementarity as a continuum with customers' exclusive use of service relationships as one pole and their exclusive use of SST as the other, this research examines the factors that impact how customers pick their location along this continuum. Understanding the reasons underlying the customers' mode of interacting with the firm helps service organizations determine the optimal zone along the relationship-SST continuum and ways of moving their customers to such a location.
When did ADDIE become addie

Training departments must earn the right to move from being training order-takers and providers to improvers of individual and organizational performance using human performance technology. The starting point for this transition is providing quality training that produces measurable results of value to the organizations the departments serve. To earn this right to truly focus on improving workplace performance, training departments must build a reputation for conducting rigorous analysis followed by improved design, development, and implementation of training solutions that produce measurable results. Only then will their organizations be ready to allow them to expand their role.
Design and modeling of clock and data recovery integrated circuit in 130 nm CMOS technology for 10 Gb/s serial data communications

This thesis describes the design and implementation of a fully monolithic 10 Gb/s phase and frequency-locked loop based clock and data recovery (PFLL-CDR) integrated circuit, as well as the Verilog-A modeling of an asynchronous serial link based chip to chip communication system incorporating the proposed concept. The proposed design was implemented and fabricated using the 130 nm CMOS technology offered by UMC (United Microelectronics Corporation). Different PLL-based CDR circuits topologies were investigated in terms of architecture and speed. Based on the investigation, we proposed a new concept of quarter-rate (i.e. the clocking speed in the circuit is 2.5 GHz for 10 Gb/s data rate) and dual-loop topology which consists of phase-locked and frequency-locked loop. The frequency-locked loop (FLL) operates independently from the phase-locked loop (PLL), and has a highly-desired feature that once the proper frequency has been acquired, the FLL is automatically disabled and the PLL will take over to adjust the clock edges approximately in the middle of the incoming data bits for proper sampling. Another important feature of the proposed quarter-rate concept is the inherent 1-to-4 demultiplexing of the input serial data stream. A new quarter-rate phase detector based on the non-linear early-late phase detector concept has been used to achieve the multi-Giga bit/s speed and to eliminate the need of the front-end data pre-processing (edge detecting) units usually associated with the conventional CDR circuits. An eight-stage differential ring oscillator running at 2.5 GHz frequency center was used for the voltage-controlled oscillator (VCO) to generate low-jitter multi-phase clock signals. The transistor level simulation results demonstrated excellent performances in term of locking speed and power consumption. In order to verify the accuracy of the proposed quarter-rate concept, a clockless asynchronous serial link incorporating the proposed concept and communicating two chips at 10 Gb/s has been modelled at gate level using the Verilog-A language and time-domain simulated.
