Clothoid-based Lane Change Trajectory Computation for Self-Driving Vehicles

The subject of this paper is the efficient computation of lane change trajectories for self-driving vehicles. The paper first identifies that a certain type of clothoid-based bi-elementary paths can be used to represent lane change trajectories for vehicles. It is further highlighted that the curvature of such trajectories must be adjusted to the driving situation in order to...

Hypercyclic Weighted Composition Operators on ℓ^2 (Z)

A bounded linear operator T on a separable Hilbert space H is called hypercyclic if there exists a vector x ∈ H whose orbit {T n x : n ∈ N} is dense in H . In this paper, we characterize the hypercyclicity of the weighted composition operators Cu,ϕ on ℓ 2 (Z) in terms of their weight functions and symbols. First, a necessary and sufficient condition is given for Cu,ϕ to be...

Solid Oxide Fuel Cell Thermodynamic Study

The aim of this work is the solid oxide fuel cell (SOFC) thermodynamic study. Particular attention is given to the electric power optimization. The Nernst potential and the over-potentials that are due to the concentration polarization, activation polarization and to the Ohm polarization represent the fuel cell potential. A FORTRAN language program was developed locally for the...

Assessment of the Use of AutoCAD in Mechanical Engineering Technical Drawing Education

AutoCAD is one of the widely used software tools in engineering education. In this study, a general assessment of AutoCAD for the usage in the mechanical engineering technical drawing education is made. AutoCAD is assessed in terms of the fulfilment of the requirements defined for the main two technical drawing courses. AutoCAD is assessed in terms of its capability in meeting...

Hyper Lattice Implication Algebras and Some of Their Characterizations

In this paper, we introduce the concept of hyper lattice implication algebras which is established by combining the concept of hyper lattices and hyper implication algebras. We give some important examples of hyper lattice implication algebras and obtain some of their properties. Then, we characterize hyper lattice implication algebras in which 1 is an implication scalar element...

Dynamical Behavior of HBV in a Population

The present study investigates a mathematical model for HBV carried out in a district of Kerman. The statistical sample comprises all men and women living in that district. Two different mathematical models are introduced for HBV related to this population. Data analysis was carried out with MATLAB programming. The results indicate that there is a meaningful relationship between...

An Approach to Some Properties of Fuzzy Topological Spaces

In this manuscript, we use a specific definition of a fuzzy topological space. We define some basis structures of this topology and survey properties of them such as the concepts of F-closure, F-interior and F-limited points of a fuzzy subset of a topological space. Moreover, we redefine the concepts of the basis and subbasis of this topology and discuss about continuous related...

Evaluation of Range-Free Localization Algorithms Against Node Compromise Attack

Different range-free algorithms are proposed for location estimation in Wireless Sensor Networks. In these algorithms, the network is assumed to have no error and false data. This article attempts to evaluate and compare the effect of malicious data produced by node compromised attacks in some of the range-free algorithms: DV-hop, LSVM, and NN. The false data may be produced by...

Analysis of Hybrid Multilevel Inverters Using a Reduced Voltage Stress Switch

In this paper, a new multilevel inverter topology using a reduced number of switches, insulated gate driver circuits and voltage standing on switches is proposed. The presented topology is a hybrid modular multilevel inverter. The operation of the proposed inverter is the same as the conventional threelevel inverter. The proposed converter creates positive and zero voltages in...

Stepwise Solutions for Optimal Control Problems

A new stepwise method for solving optimal control problems is introduced. The main motivation for developing this new approach is the limitation of the continuous-time Pontryagin Maximum Principle (PMP) where all control functions must be continuous. However, in many real-world applications such as drug injection or resource allocation problems, it is not practical to...

On Some Properties of the Space Lpw(Rn) and Lqt(Rn)

Subsequently by using Fourier transform we have the exact solution of conformable Burgers’ equation with fractional order

On Graded 2-Absorbing and Graded Weakly 2-Absorbing Ideals of a Commutative Ring

Let G be a group with identity e and R be a G-graded commutative ring with 1 6= 0. In this paper, we study the graded versions of 2-absorbing and weakly 2-absorbing ideals which are generalizations of the graded prime and graded weakly prime ideals, respectively. A graded proper ideal I of R is called a graded 2- absorbing (resp. graded weakly 2-absorbing) ideal if whenever abc...

An Experimental Study Related to Dose Scattering on the Routinely Used Minerals with Comparison of Grain Sizes and Disks Materials

The determination of the dose rate of a 90Sr/90Y radiation source prevalently used for luminescence dating studies was investigated over quartz, feldspar and polymineral aliquots in different grain sizes. These minerals are deposited over commonly used stainless-steel and aluminium discs. Luminescence dating includes protocols incorporating artificial irradiation, which is a...
