Abstract

Nowadays, computational intelligence is frequently used in diagnosis and determination of the severity of various diseases. In fact, different tools of computational intelligence help physicians as an assistant to diagnose with fewer errors. In this article, a fuzzy Hopfield neural network has been used for determination of severity of the famous disease of hepatitis. This disease is one of the most common and dangerous diseases which endangers the lives of millions of people every year. Diagnosing this disease has always been a serious challenge for physicians and thus we hope this study to be helpful. The data was extracted from UCI and it has 19 fields and 155 records. After training and testing the fuzzy Hopfield neural network and the comparison of its performance with various neural networks Multilayer Perceptron (MLP) structure trained by standard back propagation, Radial Basis Function (RBF) network structure trained by OLS algorithm, GRNN, BNNF, BNND and HNN  , it was found that it has a good performance and was able to diagnose the severity of hepatitis with 92.05% accuracy.

Abstract

The studies that have been made to ensure the quality of engineering education accelerate all over the world and also in Turkey. Not only the cheapest or the most profitable solutions but also the optimal solutions which respond to demands of the students, who can be defined as customers of teaching activities, should be investigated for more valuable and qualifying engineering education. For this reason, the student's needs and consequently teaching strategies within the scope of value engineering have to be evaluated. In this study a survey was applied on 301 undergraduate students from 6 different civil engineering departments. Scientific development of the faculty and the department, quality of lectures and transportation opportunities of the city etc. were investigated. Surveying results were statistically evaluated and the assessments have been made about the higher education institutions utilizing by value engineering principles. According to the results, civil engineering education seems to be lacking suitable basis, physical places and equipment, except for a few qualified universities.

Abstract

The badlands topography of Nolia Nuagam Village, Ganjam District, Odisha, possesses red sediments. The typical red sediment fluvial placer deposit contain on average 83.2% total heavy minerals (THM), out of which 78.2% are ilmenite. The other heavy minerals contain sillimanite 4.9%,  zircon 0.8%, rutile 0.6%, garnet 0.7%, monazite and other minerals are present in small quantities. The quartz containing 12.1% by weight is the major gangue mineral. The ilmenite concentrate recovered using wet high-intensity magnetic separator followed by high tension separator from the THM concentrate which can be used in titanium pigment and iron-steel industries.

There are many approaches to recover titania from ilmenite mineral. Reduction of ilmenite and recovery of titania slag from conventional furnace or plasma process is one of the approaches. Microwave energy has potential for the efficient heating of minerals. On applying the electromagnetic field in microwave furnace, the mineral sample heat at different rates. Minerals or materials, which couple to microwave energy are called dielectrics and many valuable minerals are found to be dielectric. The placer ilmenite mineral is one which also shows good dielectric heating characteristics. In this present investigation, the effect of microwave reduction of oxidized ilmenite is attempted by using the microwave sintering furnace. The graphitic carbon as a heating agent is used for reduction of ilmenite. The results of preliminary investigations reveal that there is a titania phase formation by using microwave sintering furnace from oxidized ilmenite. These observations are confirmed from XRD studies and SEM -image mapping.

Abstract

Analyzing the nearly collapsed and broken structures gives a good insight in the possible architectural and engineering design mistakes, faults in the detailing and the mismanagement of the construction by the building contractors. Harmful vibration effects of construction operations occur frequently. The background reviews have demonstrated that the problem of vibration serviceability of long-span concrete floors in buildings is complex and interdisciplinary in nature. In public buildings, floor vibration control is required due to meet Serviceability Limit States that ensure comfort of users of a building. In industrial buildings, machines are often placed on floors. Machines generate vibrations of various frequencies which are transferred to supporting constructions. Precision machines require a stable floor with defined and known dynamic characteristics. In recent years there has been increasing interest in the motion of elastic bodies whose material properties (density, elastic moduli, etc.) are not constant, but vary with position, perhaps in a random manner. Concrete is a non-homogeneous and anisotropic material. Modeling the mechanical behavior of Reinforced Concrete (RC) is still one of the most difficult challenges in the field of structural engineering.

One of the several methods for determining of the dynamic modulus of elasticity of engineering materials is the vibration frequency procedure. In this method, the required variables except modulus of elasticity accurately and certainty determined.

In this research, uncertainly analysis of free vibration of inhomogeneous orthotropic reinforced concrete plates has been investigated. Due to the numerous outputs obtained, software package has been written in Matlab and analysis on the data and drawing related charts have been done.

How Construction Errors Affecting the Bearing Capacity of the Concrete Beams? Inelastic Deflection of Concrete I-Beams

Hussein Khalilimarda

aPhD. Student of Civil Engineering, AZUAC, Azerbaijan University of Architecture and Construction, Baku, Azerbaijan

Abstract

Reinforced concrete I-beams are widely used in bridge construction. The span length to beam height ratio in these decks is sometimes between 15 and 30. Due to the widespread utilization of these bridges and their heavy traffic loads, special attention must be directed at recognizing the behaviors that lead to construction errors associated with these structures. Because of various construction and environmental factors, construction faults might result in concrete quality or during concrete placement which can consequently lead to inhomogeneities in beam sections. This means that concrete density and compressive strength in the beam cross section might deteriorate along the section height.

Extensive research has been conducted on the non-linear and inhomogeneous behavior of concrete beams. However, few researchers have specifically addressed density and compressive strength variations along beam cross sections. The present research is aimed at estimating from elastic material parameters, the concrete I-beam inelastic deflection resulting from inhomogeneous behavior along the beam cross sectional height. The behavior of the beam under study was checked by comparing its relevant parameters with the results obtained from the OpenSees Software and the method proposed in the Concrete Code ACI318. Excellent agreement was observed in both cases. Moreover, a value of unity was proposed for parameter “n” in the relation set forth by Branson in the Concrete Code ACI318 for estimating section cracking moment in long span I-beams.

Abstract

Propeller aircrafts have seen many up and downs throughout their usage in aviation history. Due to current economic recession and fuel hikes, propeller aircraft are yet again a choice for aerial transport and thus re-emerged as an active area for future research. On modern aircraft old Aluminum type propellers are being replaced with Fiber Reinforced Composite propellers. On the other hand owing to their reliability, strength and integrity, Aluminum propellers are still being used in military aircrafts. One of the challenges that users of these aircraft type have to deal with is the non-availability of the engineering drawings of these propellers. Thus, it is practically impossible to carry out any study, research or modification on such propellers in the absence of correct CAD data. This article proposes a methodology wherein a CAD model of C-130 aircraft propeller blade are to be constructed using reverse engineering techniques. The CAD model to be developed would help in the future aerodynamic as well as structural analyses; this includes investigating structural integrity and studying fluid dynamics of propeller blades. Different steps involved in this process have been discussed; starting from laser scanning to getting a point cloud data and subsequently generating CAD model in a commercial CAD software. It was then imported in to analysis software where quality surfaces mesh is generated, using all tetrahedral elements. The purpose is to prepare a meshed model for future computational analysis including CFD (computational fluid dynamics) and FE (Finite Element) analysis.

Abstract

The microstructure, x ray diffractive study and simultaneous thermal analysis of the novel Ti50Ni48Nb2, Ti50Ni46Nb4, Ti50Ni44Nb6, Ti50Ni42Nb8, Ti50Ni40Nb10 and Ti50Ni38Nb12 shape memory alloys were investigated. The dominant phase is titanium nickelide TiNi (B2 phase) intermetallic compound with the ordered bcc CsCl lattice. There is a significant content of the bcc niobium phase. Along with these phases, it contains a strong line of the fcc Ti2Ni phase. STA results shows that there is no transformation change in this range of temperature. Due to the addition of Nb decreases the transformation temperature, so that these alloys have sub-zero transformation temperature. To find out the transformation temperature of these alloys further investigation is required. The identification of the phases in the Ti–Ni–Nb alloys shows that the dominant phase is TiNi (B2 phase) intermetallic compound, which is seen as coarse gray grains of rounded or dendrite shapes. In the present study Grain boundaries are decorated with white rounded pure niobium inclusions. A softer structural component, namely, the (Ti, Ni, Nb) eutectic, contains isolated dark gray inclusions of nickelide Ti2Ni alloyed with niobium.
