It can decode 162 instructions of the Java Virtual Machine (JVM)'s opcodes and it has a set of proprietary instructions. The pipeline has four instruction buffers and four decode queues to overcome the pipeline stalls on decoding the variable length instructions of the JVM. The processor also executes a restricted set of instruction folding and a restricted set of instruction reorder. In addition it has a caching scheme for the fast execution of the array instructions of the JVM.
Recording Techniques and their Effect on Sound Quality at Off-Center Listening Positions in 5.0 Surround Environments

Assessments of listener preferences for different multichannel recording techniques typically focus on the sweet spot, the spatial area where the listener maintains optimal perception of the reproduced sound field. The purpose of this study is to explore how multichannel recording techniques affect the sound quality at off-center (non-sweet spot) listening positions in medium-sized rooms. Listening impressions of two musical excerpts created by three different multichannel recording techniques for multiple off-center positions are compared with the impression at the sweet spot in two different listening room environments. The choice of a recording technique significantly affects the sound quality at off-center positions relative to the sweet spot, and this finding depends on the type of listening environment. In the studio grade listening room environment featuring a standard loudspeaker configuration, the two tested spaced microphone techniques were rated better at off-center positions compared to the coincident Ambisonics technique. For the less controlled room environment, the interaction between recording technique and musical excerpt played a significant role in listener preference.
A practical neural network for handwritten character recognition built by dynamics-based active learning and self-organization of feedback mechanism

A feedback mechanism which enhances similarity between recognition by a human and that by an artificial neural network we have proposed is introduced. A human may turn his attention to a particular portion of the object in order to classify it successfully. It is regarded as a feedback from the first rough classification to the final one. The proposed feedback mechanism is designed to simulate such attention. The recognition rates by a neural network with the feedback mechanism exceed those by a former neural network.

Amplificador MHEMT cascodo de bajo ruido a 100 GHz

We report the complete design of a Cascode Low Noise Amplifier (LNA) MMIC operating in a band between 94 and 100 GHz, based on microstrip technology using a process which employs 0.07 μm Metamorphic High Electron Mobility Transistors. A modified Cascode configuration combining resistive feedback and a lossy network to equalize gain and stabilize the circuit is used. Differences between electromagnetic simulation and circuital equivalent models of passive parts in these frequencies are discussed. Expected performance features small signal gain over 11 dB, a minimum Noise Figure of 2.2 dB, being below 2.5 dB in the whole band, input and output matching better than -15 dB/-8 dB. MonteCarlo analysis was done to ensure a robust design obtaining yield figures above 80% for the main specs.
Analysis And Implementation Of Multi-Rate Cascaded Integrator Comb (CIC) Interpolation & Decimation Filter With Compensation Filter For Software Defined Radio

I Abstract Software defined radio (SDR) is a radio in which the properties of carrier frequency, signal bandwidth, modulation ,and several other characteristics are defined by software. Normal FIR architectures and its variants fail to work at such high frequencies. Cascaded Integrator comb (CIC) decimation filter is useful to reduce the data sampling rate such high bandwidth applications The implementation of decimator & interpolator using MATLAB as standard FIR and cascaded integrator comb filter by using the multistage design techniques. The hardware saving can be achieved by using multistage Nyquist decimator design. It Reduces computational work load, lower filter order, lower coefficient sensitivity and noise and less stringent memory requirements. This paper also presents a simple design of compensation FIR filter for CIC decimation filter which will correct the passband droop. Compensation filter design consists of polynomial based design of FIR filter which are used in cascade with CIC filter. The resulting structure is multiplier less and exhibits small passband droop in comparison to CIC filter. It modifies the frequency response of CIC decimation filter while maintaining the linear phase
CAD Software Evaluation for Product Design to Exchange Data in a Supply Chain Network

The sharing information in a supply chain environment, especially CAD models and drawings are so important companies. So, the selection of the most satisfying computer-aided design (CAD) software which enables to exchange data through supply chain network has been major issues for companies in a supply chain. The selection process of CAD software among the raising number of alternatives in the market has been very vital and critical issue for companies that aim to make their design and engineering related activities automated towards computer integrated manufacturing (CIM) environment. Therefore, most companies have used various methods to successfully carry out this difficult and time-consuming process. Of these methods, Analytic Hierarchy Process (AHP) has been widely used for Multiple Criteria Decision Making (MCDM) problems in both academic researches and practices. But, in some cases, due to the vagueness and uncertainty on judgments of the decision- maker(s), the crisp pair wise comparison in the conventional AHP seems to be insufficient and imprecise to capture the right judgments of decision-maker(s). Therefore, a fuzzy logic is introduced in the pair wise comparison of AHP to make up for this deficiency in the conventional AHP, called as fuzzy AHP. In this paper, a fuzzy AHP-based approach is proposed to evaluate a set of CAD software alternatives in the market to reach the best satisfying one based on the needs of company.
Pilot-assisted technique on LDPC-coded COFDM-CDMA in frequency-selective multipath fading channels

The low-density parity-check code is known for a superior signal reception capability in AWGN and/or flat fading channels with respect to increased encoding rates, however, its performance degrades when the communication channel becomes multipath fading. In this paper we have investigated a novel approach applying a pilot-assisted LDPC coding to a coded OFDM-CDMA system, which operates in a multipath fading mobile channel. In a typical multipath fading mobile channel with a SNR of 16 dB or lower, however, it is a challenging problem to obtain a BER lower than 1 out of I0/sup 5/ when the LDPC encoding rate is about 1/4. In order to enhance the performance of the proposed system we have improve the LDPC decoding algorithm by incorporating the pilot information with the parity check bit. In contrast to the conventional 1/4-rate LDPC coded transmission symbol that is consisted of data bits and parity-check bits in 1 to 3 proportion, in the proposed method the same rate LDPC transmission symbol contains data bits, parity-check bits, and pilot bits in 1 to 2 to 1 proportion, respectively. The included pilot bits are effective not only for channel estimation and equalization but for LDPC symbol decoding by assisting the parity-check bits. The proposed system performance has been verified using computer simulations in multipath, Rayleigh fading channels, and the results show us usefulness of the proposed method over the conventional LDPC coding methods in terms of SNR vs BER measurements.
New Method to Optimize Initial Point Values of Spatial Fuzzy c-means Algorithm

Fuzzy based segmentation algorithms are known to be performing well on medical images. Spatial fuzzy C-means (SFCM) is broadly used for medical image segmentation but it suffers from optimum selection of seed point initialization which is done either manually or randomly. In this paper, an enhanced SFCM algorithm is proposed by optimizing the SFCM initial point values. In this method in order to increasing the algorithm speed first the approximate initial values are determined by calculating the histogram of the original image. Then by utilizing the GWO algorithm the optimum initial values could be achieved. Finally By using the achieved initial values, the proposed method shows the significant improvement in segmentation results. Also the proposed method performs faster than previous algorithm i.e. SFCM and has better convergence. Moreover, it has noticeably improved the clustering effect.

DEVELOPMENT OF A FORMAL FRAMEWORK FOR USABLE OPERATIONS SUPPORT IN E-HEALTH BASED SYSTEMS

This study uses advanced communications and computing technologies to support health care delivery and education. The automated e-Health-based system was designed to eliminate clumsy and tedious treatment procedures associated with manual treatment processes prevalent in care centres, especially in the developing countries. The operations support functionalities of the system are provided within a formal framework to eliminate system errors, improve dependability and enhance its usability. The framework presented in this thesis uses algebraic specifications in object constraint language (OCL) and Unified Modelling Language (UML) in the analysis and design of some subsystems in an e-Health based system. Wireless Markup Language (WML) and Java programming language were used to develop the operations support functionality with real-time access to medical information via hand-held devices. The application was deployed on a 3-tiered client / server architecture with hand-held devices as clients, providing mobile access to real-time information from server-based systems within a care centre. The system was evaluated empirically and analytically. The application’s usability evaluation was done using a questionnaire based on the attributes suggested by ISO, ANSI and ITU. The product was found to be usable with a mean rating above 4 on a scale of 5 for all attributes used for the measurement. The study revealed that 92% of the medical professionals who evaluated the application would like to see it deployed for use in medical centres in order to enhance health care delivery.
Analysis and Optimization of Cooperative Wireless Networks

Tran, Phuong T. Ph.D., Purdue University, December 2013. Analysis and Optimization of Cooperative Wireless Networks. Major Professor: James S. Lehnert. Recently, cooperative communication between users in wireless networks has attracted a considerable amount of attention. A significant amount of research has been conducted to optimize the performance of different cooperative communication schemes, subject to some resource constraints such as power, bandwidth, and time. However, in previous research, each optimization problem has been investigated separately, and the optimal solution for one problem is usually not optimal for the other problems. This dissertation focuses on joint optimization or cross-layer optimization in wireless cooperative networks. One important obstacle is the non-convexity of the joint optimization problem, which makes the problem difficult to solve efficiently. The first contribution of this dissertation is the proposal of a method to efficiently solve a joint optimization problem of power allocation, time scheduling and relay selection strategy in Decode-and-Forward cooperative networks. To overcome the non-convexity obstacle, the dual optimization method for non-convex problems [1], is applied by exploiting the time-sharing properties of wireless OFDM systems when the number of subcarriers approaches infinity. The second contribution of this dissertation is the design of practical algorithms to implement the aforementioned method for optimizing the cooperative network. The difficulty of this work is caused by the randomness of the data, specifically, the randomness of the channel condition, and the real-time requirements of computing. The proposed algorithms were analyzed rigorously and the convergence of the algorithms is shown.

User's manual for ZETUP, the set up program for the groundwater flow model ZOOMQ3D

ZETUP is the pre-processor for the finite difference groundwater flow model ZOOMQ3D. It is used to construct the model grid, which may contain multiple areas of local grid refinement, and to create rivers within these complex meshes. ZETUP produces the input files required by ZOOMQ3D that define the structure of the model mesh and the structure of rivers (Table 1). It also produces templates of all of the other files required by ZOOMQ3D (Table 2) in the correct format. These can subsequently be modified using a text editor to complete the model specification. Finally, it produces a set of files that enable the visualisation and checking of the model structure (Table 3). If modifications to the structure of the model are required, it can be reloaded into ZETUP for alteration. Only the checking files listed in Table 3 are described in detail within this manual. Detailed descriptions of the files listed in Table 1 and 2, which form input to ZOOMQ3D are presented in the ZOOMQ3D manual (Jackson & Spink, 2004).
Multimedia Applications for MANETs over Homogeneous and Heterogeneous Mobile Devices

Mobile Ad Hoc Networks (MANETs) are considered a vital part in beyond third generation wireless networks (Nicopolitidis et al., 2003). In the matter of fact, they present a new wireless networking paradigm. Any sort of fixed infrastructure is not used byMANETs. They are important sorts of WLANs, therefore, in a distributed and a cooperative environment, MANETs do efficiently function (Murthy and Mano, 2004) (Sarkar et al., 2008). MANETs are networks of self-creating since there is a lack of routers, configuration prior to the network setup, Access Points (APs) and predetermined topology (Wu et al., 2007). MANETs are as well networks of self-administering and self-organizing. This is because in the network creation process, there is no application for central control. On MANETs, it is extremely hard to apply any of the central administration types, for instance, congestion control due to the dynamic nature of the network topology in MANETs, authentication or central routing. In short, several important applications benefited from MANETs, for example, in military, ubiquitous, emergency and collaboration computing.
REACTION TIME MEASUREMENT APPLIED TO MULTIMODAL HUMAN CONTROL MODELING

The final goal of this research is to analyze the human visual and force sensory feedback integration related to a manipulation task and build a control model of a human operator. In this primary work the reaction time was measured to determine the time lag constant of each subject. During the measurement of the reaction time, fluctuations in the pupil size and heart beat were verified and the both had first order lag characteristics but there were no correlation with each other. In order to improve the human control model the identification and implementation of this kind of fluctuation will be discussed.

Spanish abstract. El computo de alto rendimiento es una necesidad para el desarrollo de investigaciones con grandes volumenes de datos. La creciente demanda de este tipo de resultados ha impulsado a varios centros de investigacion a poner en funcionamiento recursos de computo de alto rendimiento. En Cuba no existe una solucion definitiva que permita a todos los centros de investigacion disponer de los recursos de computo necesarios para desarrollar sus proyectos. Este trabajo propone el empleo de un cluster de computadoras de la Universidad de Griffith a traves de una interfaz basada en el correo electronico. Esta solucion permite disponer de recursos de computo de alto rendimiento sin necesidad de una alta conectividad. Como caso de estudio se analizan los resultados obtenidos en un proyecto de optimizacion global en grandes dimensiones desarrollado en la Universidad de La Habana. Para experimentos con un mes de duracion (en una computadora estandar) los resultados muestran que al utilizar el recurso de alto rendimiento es posible alcanzar un incremento en el rendimiento relativo superior al 1300%. English abstract. Research with large volumes of data usually require access to High Performance Computing. The increasing demand for this kind of research has led many institutions to develop their own computer clusters. However, in Cuba there is no definitive solution for the High Performance Computing requirements of institutions such as the University of Havana. The expenses of building a computer cluster disallows many institutions to have their own, while the low connectivity limits the use of international high performance computing services. This research presents an alternative solution based on the development of an email-based platform for accessing a computer cluster at Griffith University in Australia. This new communication interface has been successfully used on a Large Scale Optimization research project at the University of Havana. Computational results show that by using the remote cluster it is possible to improve upon the performance of a personal computer by up to 1300%.
