Computational methods for post-translational modification (PTM) site prediction play important roles in protein function studies and experimental design. Most existing methods are based on feature extraction, which may result in incomplete or biased features. Deep learning as the cutting-edge machine learning method has the ability to automatically discover complex representations of PTM patterns...
A Lyapunov-based construction of a predefined-time stabilizing function (a function that stabilizes a system in fixed-time with settling time as function of the controller parameters) for scalar systems is considered in this paper. The constructed function involves the inverse incomplete gamma function, causing this function to be semi-global, i.e., the domain of definition of the function can be...
Accurate detection of cyber-attacks plays a central role in safeguarding computer networks and information systems. This paper addresses the problem of detecting SYN flood attacks, which are the most popular Denial of Service (DoS) attacks. Here, we compare the detection capacity of three commonly monitoring charts namely, a Shewhart chart, a Cumulative Sum (CUSUM) control chart and exponentially...
This paper presents a collaboration between the University of Puerto Rico-Mayaguez (UPRM) and a community to establish Puerto Rico's first solar community in the southern part of the Island. This community-university collaboration is leveraging on well-organized community leadership and their efforts towards community self-reliance. Electrical engineering capstone design projects have been used as...
A framework for hardware design and validation of face detection systems is discussed. The design begins at a high-level of abstraction by using a software library as the golden reference model. The golden reference model and the baseline model (model under validation) are converted to a transaction level (TLM) description or a register transfer level (RTL) description. The degree of similarity of...
This paper considers the observer design problem for the SISO Lur'e differential inclusion system. The feature of the observer lies that it does not hold any set-valued mappings. Different from the current works, the system with relative degree more than one is studied in this paper, and the observer is constructed by the filtering transformation method. A numerical example is simulated to show the...
Although quite recently our diversity and inclusion core values were challenged, we should not forget to recognize the importance and value of bringing together students from underrepresented minorities and their different perspectives into our various workplace processes one day. Unfortunately, most of the outreach efforts in Science, Technology, Engineering, Mathematics and Computer Science (STEM-C)...
The block oriented structure such as Hammerstein, Wiener, etc… became very popular for the non-linear system modelling due to its simplicity and parsimony. In this paper, fractional hammerstein system is considered; it consists of a static non-linear block followed by a fractional linear dynamical block. The particle swarm optimisation is used to estimate the system parameters as well as the fractional...
This article addresses the inverse kinematic problem of the general 6R serial robot via unit dual quaternion and Dixon resultant. Firstly, we show quaternion and dual-quaternion. Secondly, by the quaternion and dual quaternion theory, unit dual quaternion kinematics equations of 6R robots are derived. Thirdly, the solution process was constructed via elimination method and Dixon resultant; According...
This paper studies designing resilient asynchronous H∞ state feedback controller for Markov jump systems with transition probabilities partly unknown. By Finsler's Lemma, and with the help of three matrices with special structure, the problem of inter connection between the Lyapunov matrices and the system matrices is solved. In order to make the theory have more practical value, this paper considers...
This paper considers the non-fragile sampled-data (SD) control problem of semilinear parabolic partial differential equation (PDE) systems. By using a Lyapunov functional (LF), a non-fragile SD controller is proposed to stabilize exponentially the PDE system. The stabilization condition is presented by linear matrix inequalities (LMIs). Finally, simulation results are provided to control the the FitzHugh-Nagumo...
In this paper, we study the problem of moving target detection in video sequences. An improved frame difference target detection algorithm is proposed on the basis of the self updating average background model. By using numerical difference and logical operations between the average background and the current frame, the empty areas which are derived from traditional frame difference method can be...
Motivated by recent drastic advances in the study of linear-time invariant (ETI) positive systems, we explore analysis techniques of general, not necessarily positive ETI systems using positive system theory. Even though a positive system is characterized by its peculiar property that its impulse response is nonnegative, we often deal with nonnegative impulse responses even in general ETI system analysis...
This paper presents two constructions of Gaussian integer Z-periodic complementary sequence (ZPCS) sets. Construction I employs a ZPCS set as the original sequence set, however, the parameters of the resultant sequence sets cannot be flexibly chosen. Construction II generates Gaussian integer ZPCS sets using an orthogonal matrix, the ZCZ length and the flock size have flexible choices. The sequences...
Dynamical colony pattern formation in motile cyanobacteria Pseudanabaena sp. was investigated. Collectives of the bodies are self-organized and form various motile colony patterns on agar plates. The coexistence of collective movements of four types was observed: translationally moving single strands, bundles, comet-like colonies, and a rotating disk. Additionally, the colony patterns switch to others...
Dempster's rule of combination is a core part in evidence theory. However, it may generate an unreasonable result when fusing conflicting evidences. For the sake of dealing with such a problem, a novel discounting method is proposed. Minimum singular value of BPA (basic probability assignment) matrix consisting of two BPAs corresponding to two evidences can measure the dissimilarity between these...
This paper presents the first proposition of a method allowing the determination of a set of (A, B, C, D) realizations of the one-dimensional single-input multi-output (SIMO) dynamic system from created digraph. The algorithm presented is the extension of previously published algorithm that finds a complete set of all possible realizations, instead of only a few realizations, as was in case of canonical...
Feature selection has been studied widely in the literature. However, the efficacy of the selection criteria for low sample size applications is neglected in most cases. Most of the existing feature selection criteria are based on the sample similarity. However, the distance measures become insignificant for high dimensional low sample size (HDLSS) data. Moreover, the variance of a feature with a...
This paper elucidatesa new improved optimization algorithm for economic Load dispatch (ELD) problem using self-adaptive real coded genetic algorithm. The ELD dilemma is formulated as a single-objective on-linear constrained optimization problem gratifying both equality and inequality constraints. The regeneration of population practice is integrated to the conventional real coded genetic algorithm...
In this paper, finite-time synchronization (FTS) problems in an array of unified chaotic and hyperchaotic systems are mainly studied using some important control methods. First, FTS and finite-time transmission synchronization (FTTS) for N systems are realized in a finite time by designing the effective control schemes, and the stability criteria can be given. The corresponding examples are presented...
