In this paper, we suggest a shortest trajectory planning algorithm for wheeled mobile robots with constraints; bounded curvature paths and moving forward only motion of robots; for example, aerial vehicles or moving forward car-like mobile robots. The main purpose of the paper is to find the optimal shortest path between a starting point and a goal point(More)
In this paper, we present Petri-nets (PN) based modeling of biological process. Carbohydrate metabolism, which plays an important role in the regulation of the glucose concentration in the blood, is modeled and analyzed. The breakdown of carbohydrate occurs in a series of steps and the final outcome of the carbohydrate anabolism is generation of ATP, water(More)

This paper presents a modified localization scheme of a mobile robot. When it navigates, the position error of a robot is increased and doesn 't go to a goal point where the robot intends to go at the beginning. The objective of localization is to estimate the position of a robot precisely. Many algorithms were developed and still are being researched for(More)
A new method of measuring blood pressure (BP) is presented. This technique involves automatic analysis of the wideband external pulse (WEP) recorded by a pressure sensor positioned over the brachial artery during standard BP cuff deflation. Three distinct components of this "K" or "WEP" signal can be defined: K1, K2, and K3 [1]. Each component has a(More)
In this paper, we introduce a new method of modeling tool for a biological process -central dogma. The deterministic Boolean Network (DBN) is used as a modeling tool of the whole process, which enables us to simulate, analyze, and manipulate (in the future) at our disposal. From DNA to protein via RNA is the one of most well-known biological process,(More)
The emphasis of this paper is on using finite automata (FA) as a modeling tool to model, simulate and analyze the process of protein production. There is tremendous potential for mathematical and computational approaches in leading to fundamental insights and important practical benefits in research on biological systems. Mathematical and computational(More)
In this paper, a new technique for measurement of SP(systolic pressure) and DP(diastolic pressure) in BP(blood pressure) using external pulse recording during cuff deflation is addressed. Frequency domain analysis such as DFT is used here and it shows three different patterns in three different `zones': above SP, between SP and DP, and below DP. As usual(More)

This paper addresses a modified localization scheme of a wheeled mobile robot. When it navigates in a square given by the operator, the position error of a robot accumulates and it never ends up with the goal position where the robot intends to go to initially. The objective of localization is to estimate the position of a robot precisely. Many algorithms(More)

In this paper, we introduce a new method of modeling tool for a biological process -central dogma. The data-flow diagram is used as a representation of the whole data input and output, which enables us to simulate, analyze, and manipulate (in the future) at our disposal.
