The value of Artificial Neural Networks (ANNs) methods in performing complicated pattern recognition and nonlinear estimation tasks has been demonstrated across an impressive spectrum of applications. ANNs methods are also used in software development process, since it is a complex environment with many interrelated factors affecting development effort and productivity. Accurate forecasting has proved...
Bluetooth provides short range low power wireless communication popularly between laptops, cellular phones and media devices. The original security measurement for Bluetooth looks somewhat inadequate today to meet many important security requirements. In this paper a public key technology based key distribution for Bluetooth is proposed. Taking advantage of `RSA for paranoids', the proposed method...
Detection of the boundaries of electrocardiogram (ECG) characteristic waves with a reasonable accuracy has been a difficult task. As a classical statistical pattern recognition algorithm characterized with high accuracy and stability, KNN has been proposed for locating the waveform boundaries (the onsets and offsets of P, QRS, and T waves) in ECG signals. First, the QRS-complex of each beat is detected...
The concomitant effect of the cardiovascular regulating mechanisms known as heart rate variability (HRV) occurs over a large set of time scales. Multiscale entropy (MSE) is a promising technique for measuring the complexity based HRV of finite length time series at different time scales. Ectopic beats, originating from other than the normal site, are the artifacts that cause a serious limitation to...
Quad-rotor-typed UAV can perform multiple targets detection effectively by its controllability and agility. In this study, the ground multiple targets detection with stochastic distances between the different targets is considered. A target position is described as a two-dimensional coordinate. The all positions' coordinates and the start-point coordinate of UAV are the sources of the algorithm. After...
Network anonymization solutions were mostly designed with a single-user usage model in mind. Indeed, the usage of such solutions in collaboration scenarios, as this is the case for social networking, could lead to network as well as application level link ability (i.e. re-identification of the end-users in these networks). Furthermore, the usage of network anonymization is not applicable in some business...
With growing demands of decimal computations in scientific, financial and many other key applications, area-time efficient hardware implementation of decimal arithmetic is desired. In this paper, we present a parallel architecture for the fixed-point decimal multiplications based on the 8421 BCD representation. By reducing the entries of partial product pre-computations and using a tree structure...
Modern modelling languages provide dedicated features to support the detailed design of complex systems from different domains. Nevertheless, especially general-purpose languages provide extensive syntactical expressiveness that, in some cases, may be hard to align with well-defined semantics. This is often inevitable due to the fact that, in order for model-driven approaches to be fruitful, modelling...
The Oracle Application Development Framework (Oracle ADF) has become increasingly important as a platform/paradigm for the purpose of building current and future enterprise projects. Such projects can easily be developed by following books and manuals. However, the process of transforming existing projects from traditional platforms, to the Oracle ADF format requires considerable effort and high levels...
Nuclear Magnetic Resonance (NMR) spectroscopy is a technique for acquiring protein data at atomic resolution and determining the three-dimensional structure of large protein molecules. A typical structure determination process results in the deposition of a large data sets to the BMRB (Bio-Magnetic Resonance Data Bank). This data is stored and shared in a file format called NMR-Star. This format is...
A novel flash fast-locking digital phase-locked loop (DPLL) is presented and behaviorally modeled using Verilog-AMS. The DPLL operation includes two stages: (1) a novel coarse-tuning stage for frequency tracking which employs a flash algorithm leading to a thermometer code as done in flash A/D converters (ADCs) and (2) a fine-tuning stage similar to conventional (classical) DPLLs. The coarse-tuning...
This paper focuses on mastering the architecture development of hardware multi-processors for modern highly demanding applications. It presents the results of our analysis of the main issues to be addressed when designing multi-processors for such applications, and discusses our new multi-processor design method which developed to address these issues. We implemented the method in the form of an automatic...
Researchers are struggling for building high reliable and energy efficient parallel disk systems for years. With the times of high energy cost, conserving energy in parallel disk systems has large impact on reducing cost of disk systems and other related backup systems. In addition, it will conserve a lot of energy consumed by parallel disks in high performance computing systems. Moreover, Disk reliability...
jHISC is an object-oriented processor with RISC core and architectural support for object instructions. It is a threeaddressing machine instead of a stack machine as JVM. With instruction folding techniques, several JVM operations could be translated into fewer or one jHISC three-address machine code, and they execute more effectively. This paper presents an improved folding algorithm for jHISC V4...
Management of a large scale distributed system presents several issues such as managing a network of thousands of nodes, keeping the system up to date when nodes are added, deleted, changed and detecting and recovering from failures. With all these challenges, required features of a distributed system vary from organization to organization. Here we present 'GajaNindu', a distributed management framework,...
Human gait walking skeleton model is proposed together with its implementation for gender classifications. The proposed model is based on morphological operations and is similar to the conventional skeleton model which allows calculations of joint angles of human body. Also gender classification method based on the proposed human gait walking skeleton model is proposed. Through experiments with the...
The CS capstone (senior project) course has two primary goals: academic and practical. The academic goal is to integrate knowledge and skills developed in other courses in the context of a real-world project, while the practical goal is to carryout software development in a simulated real-world development environment. A one-semester capstone course presents a challenge to achieving these goals in...
Researchers in environmental sciences work with datasets that have a large variety of data structures and file formats. Consequently, for data and model interoperability, it is essential to have the right tools for converting from a given data structure to another, and from a specific file format to another. In this paper, we propose an original web-enabled approach for generating data processors...
