In this study, we construct quantum error correcting codes over Eisenstein-Jacobi integers by using the CSS code construction. Since there is an isomorphism between Eisenstein- Jacobi integers and finite fields, direct constructions of quantum codes over Eisenstein-Jacobi integers can be obtained. Therefore, we define error bases, error matrices and a new distance with giving illustrative examples...
Due to abundance of oil palm waste worldwide, it is a good candidate to be used as a feedstock for synthetic natural gas for vehicles (SNGV) production. Biomass gasification is one of the promising methods for SNGV production. This work focuses on the gasification with in-situ CO2 capture using CaO as absorbent materials for SNGV production from palm oil empty fruit bunch (EFB). Two parameters (temperature...
Data centers are experiencing tremendous growth in the number of servers and networking devices with an increase in traffic to cloud infrastructures. Data center network (DCN) topology plays an important role in providing acceptable level of performance to cloud applications. This paper presents the results of a simulation studies comparing the performance of several well-known DCN topologies under...
Human action/behavior classification plays an important role for controlling systems having interaction with human users. Safety and dependability of such systems are crucial especially for walking assist systems. In this paper, upper body joint model of a user of a walking assist system is extracted using a depth sensor and a probabilistic model is proposed to detect possible non-walking states that...
This paper presents a patient-specific seizure onset detector based on the fusion of classification decisions from a common spatial pattern (CSP)-enhanced energy based detector and a neural synchronization based detector. Specifically, one level of the detector evaluates the amount of neural synchrony present within the electroencephalography (EEG) channels by calculating the condition number (CN)...
Deposition is found in many engineering processes, such as the asphaltene deposition in oil pipelines/wellbores, and biological and chemical foulings in pipes or heat exchangers. These deposition processes usually occur in a two-phase flow environment. This study develops a model for two-phase flow with deposition in vertical pipes. The model consists of three modules: Fluid Transport, Particle Transport,...
A reasonable clamping form can effectively reduce the distortion and defect in wire and arc additive manufacturing. In this paper, a three-dimensional finite element model with verified weld-bead profile and heat source model is established. Using the Simufact.welding finite element analysis software, four typical clamping forms are compared in total distortion and residual stress distribution. The...
We present different properties of circulant graphs that includes (i) On the existence of self-complementary circulant graphs; (ii) Type-2 isomorphism, a new type of isomorphism other than already known Adam's isomorphism of circulant graphs and new abelian groups; (iii) Cartesian product and factorization of circulant graphs similar to the theory of product and factorization of natural numbers.
Due to their high latent heat content, phase change materials (PCMs) have gained an increasing use for thermal storage and temperature control in many engineering applications including buildings envelop. In this paper, a numerical study of a PCM integrated multilayer light weight building wall under UAE climate is examined. First, the formulation of the finite-volume numerical method as applied to...
It is shown that the hypergraph generated by a hexagonal system is conformal if and only if the hexagonal system is catacondensed. Also, it is shown that the chromatic index of the hypergraph generated by a catacondensed hexagonal system is five. Finally, a formula for the covering number of the hypergraph generated by a catacondensed hexagonal system is given.
This paper shows a detailed modeling process for a hexacopter, taking as a control variables, the force and torques actuating on the vehicle. It also shows the hexacopter equilibrium manifold, with some numerical results that evidence the symmetry along the x and y axis. Finally, a nonlinear optimal control problem is formulated in order to see the hexacopter maneuverability capabilities, showing...
The green traveling purchaser problem (GTPP) is a generalization of the Traveling Purchaser Problem which consists of selecting suppliers, allocating orders and choosing the best routes, while minimizing the purchasing and traveling costs and CO2 emissions. The two objective functions pertaining to minimization of CO2 emissions and purchasing costs are in some cases conflicting and are thus considered...
Xpert MTB/RIF (Cepheid) and GenoType MTBDRplus (Hain Lifescience) are two widely used tests for rapid diagnosis of tuberculosis. The aim of this study is to compare Xpert MTB/RIF and GenoType MTBDRplus to determine overall accuracy of diagnosis using these two tests. Based on search on PubMed, Embase and Google Scholar databases, publications were identified that compared Xpert MTB/RIF and GenoType...
This paper presents a real case analysis of a single machine subsystem of a cable plant using reliability modelling. Real maintenance data of a cable plant are collected for this purpose. Three types of maintenance are noted for the subsystem: repair, preventive maintenance random (PMR) and preventive maintenance scheduled (PMS). The subsystem is repaired upon failure, while preventive maintenance...
A parametric study to investigate the shear behavior of short concrete beams reinforced with glass fiber reinforced polymer (GFRP) bars is presented in this paper. The parametric analysis is conducted numerically by developing a three-dimensional finite element model considering both geometric and material nonlinearities. The FE model is verified against existing experimental results [1] then extended...
this paper presents results on the simulation, modeling and optimization of an off grid hybrid solar PV/diesel/battery/inverter power system for residential application. The principal objective is to design a standalone renewable energy system to meet the desired electric load with high renewable fraction, low excess power and low cost of energy. Hourly simulations and optimization were performed...
the aims of this study is to analyze staff scheduling in the Hotel X in Kuwait, as well as, reducing waiting time in queue and developing effective customer service through finding the optimal employees schedule without hiring new staff. The study will be approached by building a simulation model using Arena in order to optimize employees scheduling within reception and housekeeping department during...
The use of manipulator on quadrotor is highly restricted due to expected arising instability problems. This paper investigates a new approach in designing manipulators mounted on quadrotors that ensures maintaining maximum MM-UAV stability. In this approach, an algorithm is used to predict the payload's mass variation that results from catching or releasing objects. The ability of the manipulator...
In this paper, the proposed CANTrack solution is described and its implementation is thoroughly explained. CANTrack is a sophisticated Computer Aided Design (CAD) tool that supports the entire development process for automotive networked systems. CANTrack differentiates itself from other competitive tools; by not only supporting planning, development, testing and finally starting-up; but also incorporating...
