A statistical approach is proposed to detect parametric fault in linear and weakly non-linear analog circuits by mapping faults to a statistical metric, Bhattacharyya distance which is measured from the Probability Density Function (PDF) of the outputs. The non-Gaussian Auto-regressive (AR) model is used to estimate the PDF. To validate the proposed statistical approach, we have simulated two benchmark...
Blind steganalysis is a method used to detect whether there is a hidden message in a media without having to know the steganography algorithm behind it. Digital image is converted into features using feature extraction algorithm subtractive pixel adjacency matrix. A model is built based on the resulting features using machine learning method support vector machine. The support vector machine method...
This paper presents results for numerical analysis of three electrostatic problems by using four MoM (method of moments) formulations while exploiting the rotational symmetry of the analyzed structures. These results are mutually compared, but also compared to the results obtained by the electrostatic solver where rotational symmetry is not considered. It is observed that exploiting the rotational...
This paper introduces how minimum variance control principles are applied to the control of human emotion - excitement signal. We use changing distance-between-eyes in a virtual 3D face as a control signal. A minimum variance control law is synthesized by minimizing control quality criterion in an admissible domain. Admissible domain is composed of input signal boundaries. Relatively high control...
In recent years statistical model checking (SMC) became increasingly popular, mainly because it does not suffer from one of the major problems that limits traditional model checking, the so called state-space-explosion problem. SMC solves this problem by simulating a stochastic model for finitely many executions. There exist a number of SMC tools, but they require the user to learn a specific modelling...
One of the most exciting applications of V2X technologies, that is envisioned, is the platooning of a series of autonomous vehicles led by a manually driven vehicle. However, the realization of this application depends entirely on the efficacy of a platoon control algorithm and the communication channel amongst the platoon members. There are many different control algorithms that are being considered...
In present paper, authors develop a model for estimation of earth slope stability based on the artificial neural networks. For this purpose, authors engage multi-layer feed-forward network with Levenberg-Marquardt learning algorithm and 14 hidden nodes, using existing experimental data, and the results of traditional limit equilibrium analyzes of 57 different cases according to the predefined experimental...
This paper introduces a probabilistic reliability management approach and describes a pilot test planned by the Icelandic transmission system operator, Landsnet, in early 2017, as part of the EU GARPUR project. The pilot test will assess the viability of the approach and criteria proposed by GARPUR, in the context of real-time system operation. The mathematical formulation of reliability assessment...
Unstable behavior of discrete-time systems cooperating with continuous-time sub-blocks is analyzed. Typical examples are the instabilities in convolution digital filters operating in feedback loops together with AD and DA converters, analog anti-aliasing and smoothing filters, and other application circuits. It is shown that the stability of such systems can, in linear cases, be tested via the location...
Spectral clustering is a suitable technique to deal with problems involving unlabeled clusters and having a complex structure, being kernel-based approaches the most recommended ones. This work aims at demonstrating the relationship between a widely-recommended method, so-named kernel spectral clustering (KSC) and other well-known approaches, namely normalized cut clustering and kernel k-means. Such...
The testability of equipment has become the key factor affecting equipment availability, and detracts from readiness and mission success. To overcome the current problems associated with the analysis of equipment testability, such as non-comprehensive failure mode coverage, low fault detection rate, and low fault location accuracy, this paper presents a system testability modeling and analysis method...
Seasional Autoregressive Integrated Moving Average (SARIMA) model was built to predict the number of tourists arrived via the Kualanamu International Airport in Medan, Indonesia. The data size was 72 periods, taken from January 2008 to December 2013 for determining models, and 23 periods from January 2014 until November 2015 for testing the model accuracy. Steps of SARIMA involve describing the data...
Nowadays, there are various types of search engines that have been developed according to the methods and the purposes of their use. In a text-based information retrieval domain, almost all search engines have similar flow and architecture which are actually reusable. Therefore, in this research we propose search application framework that developer do not have to start development from the scratch...
Having scientific publications is an evidence of a lecturer's efforts to fulfill the obligation to carry out research activities as one of the three obligations of Higher Education in Indonesia, i.e. education and teaching, research, and community service. The objective of this research is to evaluate the determinant factors of publication in Scopus by Institut Teknologi Sepuluh Nopember (ITS) lecturers...
During the performance test on site, the cooling fan speed is controlled with certain deviation from the rated condition of the cooling fan speed. This possible deviation of the fan speed is not covered in the related international standard such as VGB test guideline and etc. In order to provide a solution for this possible deviation factor on site test, a series of correction formulas are re-deduced...
In vitro fertilization technology is used to help couples get children. During the development of IVF, embryological will observe the process of cleavage embryo until it is determined which gives the highest probability to produce a pregnancy. During this division process, the observation is done manually by embryological which produce subjective assessment of an embryo and vulnerable reduced quality...
The aim of this research is to study behavior of numerical methods for solving one-dimensional stationary Schr¨odinger equation. Two testing tasks are taken for example: the probability tunneling of the square potential barrier and “hyperbolic” potential barrier. The precision and speed of various methods were evaluated.
Nowadays information retrieval based on specific queries is already used in computer system. One of the popular methods is document ranking using Vector Space Model (SVM) based on TF.IDF term-weighting. In this paper TF.IDF.ICSδF term-weighting based class-indexing is proposed, afterward comparing its effectiveness to TF.IDF and TF.IDF.ICF term weighting. Each method is investigated through Al-Qur'an...
In previous studies, no consensus has been reached on the existence of significant correlation between perception and production. A large number of empirical studies have been done upon first and second languages from different language families. However, few studies were carried out on the perception-production relation of Chinese English learners. Therefore, in the current study, under the theoretical...
Software test management is a hot field of software engineering both in academia and industry. However, traditional research are focused on software quality rather than test quality which could be evaluated by test management. Meanwhile, previous works on evaluating software test management were mostly based on statistical methods. In recently years, machine learning algorithms and techniques are...
