Abstract: In-filled frame structures are commonly used in buildings, even in those located in seismically active regions. Present IS-codes and others unfortunately, do not have adequate guidance for treating the modeling, analysis and design of in-filled frame structures. In this study all theories (techniques for modeling the infill-frame interface) are described and then one method has been applied to study the seismic response of in-filled frame structures. In this study infill walls are modeled as an equivalent diagonal strut while analysis.........

Abstract: Semisolid metal processing is carried out at temperatures ranging between its liquidus and solidus temperatures of the metal. This process is also known as thixoforming or thixocasting depending on the initial condition of the billet and process adopted. Fluidity is an important process parameter which determines the quality of the end product. Simulation studies are carried out to determine the fluidity parameter using Taguchi's design of experiments. An attempt is made to develop a mathematical model using fuzzy logic approach to predict the fluidity parameter. Some of the process conditions that are used to study the process are billet temperature ram speed and die temperature. The model was validated by experimental study.

Abstract: In nuclear and radiationfacilities, the major construction inputs are steel and concrete, which compriseover 95% of the material inputs and the main purpose of the shields is to protect operating personnel from possible injury by nuclear radiation, and in some cases, to reduce radiation exposure. Gamma-ray absorption coefficient in some shielding materials, such as concrete, is measured experimentally in the present study using point isotropic ɤ-ray sources. It is concluded that the addition of SiO2 nanoparticles improves the mechanical and nuclear properties of concrete. The increase of SiO2 nanoparticles content up to 1.5 % increases the total γ-ray attenuation coefficient μ for all energies............

Abstract: Knowledge of aerodynamic properties in agricultural products is of vital importance. In order to design efficient equipment for the harvesting and post-harvesting of coffee, it is necessary to know its aerodynamic behavior. For this reason, a subsonic wind tunnel was used to determine its behavior during the drying phase of different coffee clones. For the study, samples of conilon coffee (Coffea canephora) were used in different stages of maturation clones 83 and 74 of the clonal variety EMCAPA 8141 and clone 31 of the clonal variety EMCAPA 8131. The samples were placed like cluster in the test section of the tunnel to obtain the drag coefficient. The terminal velocity of each of the samples in vertical wind tunnel was also determined..........

Abstract: Fiberglass reinforced plastic (FRP) grating is manufactured by combining a resin and fiberglass. That makes it a composite material. Fiberglass grating does not corrode like steel gratings. They are used in corrosive environments. Fiber glass grating is formed using continuous interwoven glass fibers as reinforcement material and epoxy resin as the matrix with continuous solidification through a mould system. The uniform construction provides excellent bi-directional mechanical properties. It is beneficial to all industries whether it be chemical, pharmaceutical, offshore or leisure to name just a few with many applications like platforms, floorings, walkways, trench covers, ramps and cable trough covers...........

Abstract: Presses work is important in industrial activities for development of products, thus requiring optimal performance at competitive costs. The effective use of materials manufactured machinery is directly related to an appropriate stress analysis, especially if the geometry of the components are not prismatic bars, such as the frame of a stamping press which has a stress distribution very irregular and is convenient to optimize its shape, which we do by analyzing photoelasticity efforts through numerical methods and what is presented in this paper.

Abstract: An electromagnetic braking system uses magnetic force to engage the brake, but the power required for braking is transmitted manually. The disc is connected to a shaft and the electromagnet is mounted on the frame .When electricity is applied to the coil a magnetic field is developed across the armature because of the current flowing across the coil and causes armature to get attracted towards the coil. As a result it develops a torque and eventually the vehicle comes to rest..........

Abstract: Cheap fillers are added to concrete mixes to improve sustainability. Durability of such mixes is investigated. In this paper the sulfate resistance of mortar mixes containing crushed limestone and crushed dolomite fillers is investigated and compared to that of conventional mortar. Mortar mixtures with different ratios of dolomite or limestone of 10, 20, and 30%, introduced as partial cement replacement by weight,were tested to evaluate the effect of sulfate attack according to ASTM C 1012. Six prisms of each mix were exposed to sulfate for 10 weeks. It was concluded that the introduction of lime filler greatly reduces sulfate resistancewhile mixes containing dolomite fillers have almost the same sulfate resistance as conventional mixes.
