1. HAPTIC SEAT ALERT SYSTEM IN MOTORCYCLE TO REDUCE ACCIDENTS

Authors: L. JOSEPH MICHAEL

Abstract: We live in a world, where speed plays a more vital role. Though speed is more important safety is considered essential. India has recorded most number of road accident per Annam about 1,35,000 annually. The country has over taken China and now has the worst road traffic accident rate worldwide. It is found that 25 percent of the total death in the road accidents are two-wheelers. The statistics shows that, one serious road accident in the country occurs every minute and 16 die on Indian roads every hour.1214 road crashes occur every day in India. Thus an alerting system is necessary to alert the motorist, in any conditions such as over speed and rash driving also to indicate the approaching of the closer rear vehicles.The Haptic seat alert system in motorcycle is a combination of both Mechanical and Electronics operation. This system alerts the driver by producing vibration in the seat, with the help of dc vibrating motor. The system consist of Ultrasonic sensors, Electronic controllin

Authors: GEETHU VARGHESE , J.VIKRAM

Abstract: Multi-storeyed buildings are used for office, complex, residential flats, public centres, etc. There is need for multi-storeyed building due to overcrowding of cities. These multistoreyed buildings can be transformed into tall buildings in order to achieve more floor space but occupy less land space. In the design of tall buildings, lateral loads play predominant role. The lateral loads are wind load and seismic load. There are various lateral load resisting systems such as braced frame system, moment resisting frame system, frame truss-interacting system, shear wall system, core and outrigger system and tubular system. The tubular system comprises various types such as framed tube, trussed tube, tube in tube and bundled tube. In this project, a plan has been created for the bundled tube comprising four tubes using Auto-cad.The various loads such as dead load, live load and wind load are assigned using software. Analysis of the structure has been done using software. The components of

3. MECHANICAL CHARACTERIZATION OF NORMAL STRENGTH CARBON FIBERS REINFORCED CONCRETE

Authors: MANISH A. KEWALRAMANI

Abstract: Carbon fiber is a relatively new raw material which is confidently managing performance–cost trade off in construction sector. It is usually combined with other materials to form a composite. Owing to advantageous characteristics like high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion utilization of carbon fibers in construction sector is undeniably innovative. Besides, availability of various grades of carbon fibers with varying properties make it possible to be used for specific applications. The present work investigates the potential use of carbon fibers as reinforcement to normal strength concrete by studying important mechanical characteristics like compressive strength, splitting tensile strength, relationship between compressive strength and splitting tensile strength, and chord modulus of elasticity measured from stress-strain curves when high intensity long chain polymers primarily made of polyprop

Authors: SAMIR IBRAHIM SHALABY

Abstract: One of the most important problems are to construct on soft clay soil. The utilization of a cemented top layer increases bearing capacity, reduces displacement at failure, and change soil behavior to a brittle behavior. The objective of this research paper is directed towards investigating experimentally the effect of footing shapes on the bearing capacity and settlement of weak clay soil overlain by cemented or uncemented sandy soil. Two percent of cement are used as reinforcement for sandy soils. A laboratory experimental work program was carried out on circular, rectangular, and square model footings. The studied parameters include footing shape, thickness of replacement sand layer, and percent of added cement. Experimental results show that the shape of the footing has a pronounced improving effect on soil bearing capacity and its settlement. Circular footing gives the highest improvement while rectangular footing gives the least one. The critical depth of cementing upper sand laye

5. THE ROLE OF ORGANOSILICON POLYMERS IN THE FORMATION OF HYDROPHOBIC PROPERTIES OF SYNTHETIC PAINT COATINGS USED IN BUILDING RENOVATION

Authors: WACLAW BRACHACZEK

Abstract: The article studies the structure of protective coatings containing organosilicon polymers with different chemical structure, used in the building renovation. The relation between the contact angle of the cured coating and the type of the organosilicon polymer is analyzed. It has been found that the water-repellent properties of the coatings are influenced by the composition of these polymers. Using spectroscopic studies, the mechanism of hydrophobisation of coatings was explained. The analysis of spectral maps along the cross section of the coatings has shown polysiloxane additives migration from the substrate into the coating/air interface. The arrangement of polysiloxanes in cross-section of the coatings was varied and depended on the weight fraction of organic resin in the paint formulation and the chemical composition of polysiloxanes. Tests were carried out using an IR Continuum microscope. The analysis was conducted on cured coatings derived from acrylic paints containing polysi

6. ANALYSIS OF ERRORS IN RESTORATION OF SALTY AND DAMP WALLS

Authors: CEZARIUSZ MAGOTT , WACLAW BRACHACZEK

Abstract: This paper presents the study of the most common errors made in the restoration of salty and damp masonry structures. Analysis of the errors was based on site visits to 127 facilities where restoration treatment was carried out. A set of technical and technological activities aimed at permanent reduction of the moisture level in walls, usually to 3 - 6 percent of mass humidity, was evaluated in terms of correctness if their implementation. These activities included treatments related to the implementation of damp-proof membranes and a whole set of activities involving new sanitary, heating, electrical, ventilation or air conditioning installations, clearing of obstructions or changing rainwater drainage. Errors were studied in three areas: design, construction and usage. It was found that the basic errors arising during the building drying process are errors at the design stage, followed by construction and usage errors.

7. A SYSTEM MONITORING OPERATIONAL SAFETY OF STRUCTURES USED IN CIVIL ENGINEERING

Authors: JANUSZ JURASZEK

Abstract: The paper presents a system monitoring operational safety of structures used in civil engineering. The system is based on the fibre Bragg grating (FBG) sensors or sensors using the optical time domain reflectometry (OTDR) technology. The essence of the solution is to introduce FBG sensors into the structure to make them act as its “nervous system”. The system may be implemented in existing civil engineering structures made of steel, concrete, reinforced concrete, as well as in shells and new structures at the design stage. The paper presents an example of an actual system operating based on FBG sensors and analysing the safety of Poland's longest steel footbridge. The footbridge is 35 years old. Periodic inspections of the Technical Inspection Office allow the footbridge operation if the structure meets the requirements stipulated by relevant regulations, but the decision is not based on a continuous analysis of the footbridge safety. The applied monitoring system makes it possible to

8. A SYSTEM FOR MONITORING OF OPERATIONAL SAFETY OF FERROMAGNETIC STRUCTURES

Authors: JANUSZ JURASZEK

Abstract: The paper presents a system for monitoring of operational safety of ferromagnetic structures used in civil engineering, machine construction and power engineering. The system is based on sensors of the residual magnetic field (RMFM) distribution. A change in values of individual components of the residual magnetic field informs in advance about the appearance of areas with a raised level of stresses or stress concentration zones and identifies micro cracks. The paper presents numerous examples of identification of hazard areas both in machine construction (forging press drive shafts) and in civil engineering (transporter crane steel structure). The information obtained from the system for monitoring of operational safety of ferromagnetic structures has already made it possible to take appropriate preventive measures to avert a major catastrophe.

Authors: DRAGUTINOVIC SINISA , JOVANOVIC ZORAN

Abstract: In this paper some results concerning the effect of turbulence model variation onto flame propagation in a particular combustion chamber with four tilted valves were elucidated. Flame propagation was represented by the evolution of spatial distribution of temperature in various cut-planes within combustion chamber while the flame front location was determined by dint of zones with maximum temperature gradient. The results presented are only a small part of broader on-going research activity in the field of multidimensional modeling of reactive flows in combustion chambers with complicated geometries encompassing various models of turbulence, different fuels and combustion models. The effect of turbulence model variation was analyzed through comparison of results of flame propagation obtained with eddy-viscosity model i.e. standard k-ε model of turbulence and results obtained with k- ξ-f model of turbulence. In the case of combustion all differences ensuing from turbulence model variati

12. VISCOELASTIC KIRCHHOFF PLATE ANALYSIS VIA MIXED FINITE ELEMENT FORMULATION

Authors: FETHI KADIOGLU , GULCIN TEKIN

Abstract: In this study, a functional for the dynamic analysis of viscoelastic Kirchhoff plates is obtained through an efficient systematic procedure based on the Gâteaux Differential Method. For the solution of the derived functional, mixed finite element method in transformed Laplace-Carson space is used. In this functional, there exists four independent variables such as deflection (w), internal forces (Mx, My, Mxy) in addition to the dynamic and geometric boundary condition terms. For modeling the viscoelastic behavior, four parameter solid model is employed. For transformation of the solutions obtained in the Laplace- Carson domain to the time domain, different numerical inverse transform techniques are employed. The developed solution technique is applied to several dynamic example problems for the verification of the suggested numerical procedure.

Authors: ALI SAFARI , AMIR H. NIKSERESHT

Abstract: In recent years a great deal of research effort on ship hydrodynamics have been devoted to practical navigation problems in moving planing vessels safety in rivers and confined water. The important point of any analysis is the investigation of ship hydrodynamics in shallow water conditions. The purpose of this study is to investigate the resistance of a planing vessel model 4667-1 by using CFD software based on finite volume method to solve the RANS equations in different speed and depths including deep and shallow water conditions. Also the wave pattern and flow field around the vessel is investigated. For validating the method, at first the resistance results in deep water are compared with the experimental data and show good agreements. Simulations are performed in transient mode, using Volume of Fluid (VOF) and k -ε schemes to model the free surface turbulent flow. The results have shown that by decreasing the depth, the shallow water resistance of a planing vessel will be increase

Authors: RESAT ACAR , SEMET CELIK , SERKAN SENOCAK

Abstract: The use of artificial neural networks (ANNs) is becoming increasingly common in the analysis of hydrology and water resources problems. In this research, an ANN was developed and used to model the snowmelt runoff, in a catchment located in a semiarid climate in Turkey. The multilayer perceptron (MLP) neural network was chosen for use in the current study. The one year data (2009) obtained from the stations, located in Erzurum Kırkgöze (Çipak) basin, are integrated into daily average time series of temperature (T), solar radiation (R), snow-covered area (S), snow water equivalent (SWE), runoff coefficient for snow (Cs). The results indicate that the artificial neural network method is suitable to predict the river discharges by using some variables and parameters of snowmelt for the Kırkgöze Basin.

Authors: SANG PIL CHO , SEUNG YOON NOH , ZHE ZHU XU

Abstract: The traditional thermal error compensation system of ball screw feed drive is highly dependent on the feedback temperature or positioning data. Because of the overdependence to measuring technique, increasing of compensation system cost and decreasing of productivity level will be an inevitable trend in a machine tool. This paper presents a new approach in ball screw thermal error compensation system which can work without any temperature or positioning feedback. As the parts of the thermal error compensation system, component heat generation, compensation method, thermal model, mathematic model and calculation method were studied respectively. In order to discuss the correctness of the developed thermal error compensation system, a series of tests contains positioning accuracy and temperature distribution was carried out in the same working condition of prediction. As the results, the test data well confirmed the correctness of the developed ball screw thermal error compensation syste
