Pedestrian movement and behaviour depend on plentiful factors, among which are crossing of the lane in mid- block, movement on footpaths and at unsignalized intersections. While the previous has attracted significant research exertions for decades the later, pedestrian risk has newly become subject to collective research interest. Evidence from the 2018/19 Andhra Pradesh Police Data, is considered with further geographical context data. From this impact of parking and pedestrian movement where there is an enormous exchange of traffic c all day while controlling for various urban settings, and population density were analysed. In this study the walking ability of the pedestrians on the footpath instigated due to the impact of parking and built environment was analysed. From the study, therefore parking is an essential part of an urban developers toolbox. Providing a parking lot and collection of parking fees can be useful when stopping limit is bounteous, the pedestrian moment gets nearly multiplied. Partial access to parking at side of footpaths, mid-block and, intersections can reduce the time-lapse moment of pedestrians. The main theme of this thesis is to drive a decrease in walkability index with the provision of expanding strolling separation to the pedestrians, particularly in thickly developed zones.

This paper presents a brief introduction of composite materials followed by history, fabrication techniques, advantages and applications. A composite material (also called a composition material) is a material made from two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure. The new material may be preferred for many reasons: common examples include materials which are stronger, lighter, or less expensive when compared to traditional materials. More recently, researchers have also begun to actively include sensing, actuation, computation and communication into composites.[1] which are known as Robotic Materials. As the composite materials possess great properties, they are substituting various other conventional materials therefore, the research on composite materials must be developed further.

Random Forests are an ensemble learning method (also thought of as a form of nearest neighbor predictor) for classification and regression that construct a number of decision trees at training time and outputting the class that is the mode of the classes output by individual trees. Random Forests are a combination of tree predictors where each tree depends on the values of a random vector sampled independently with the same distribution for all trees in the forest. The basic principle is that a group of “weak learners” can come together to form a “strong learner”. Random Forests are a wonderful tool for making predictions considering they do not over fit because of the law of large numbers. Introducing the right kind of randomness makes them accurate classifiers and repressors. Single decision trees often have high variance or high bias. Random Forests attempts to mitigate the problems of high variance and high bias by averaging to find a natural balance between the two extremes. Considering that Random Forests have few parameters to tune and can be used simply with default parameter settings, they are a simple tool to use without having a model or to produce a reasonable model fast and efficiently. In this paper e proposed an efficient ensemble classifiers based on random forest using boosting and bagging.

Granite powder, one of the by-products in the granite stone crushing process, not being used for any applications other than filling up low lying areas is identified as a replacement material for cement in concrete. The quantities have been utilized and the rest has been unscrupulously dumped resulting in environmental problems. Presently, all the processing units are disposing this industrial waste by dumping it in open yards, that nearly occupying 25% of the total area of the industry. The reduction in waste generation by manufacturing value-added products from the granite stone waste will boost up the economy of the granite stone industry. The utilization of granite powder in high performance concrete could turn this waste material into a valuable resource with the added benefit of preserving the environment. Rice husk ash is found to be superior to other supplementary materials like slag, silica fume and fly ash. Due to its high pozzolanic activity, both strength and durability of concrete are enriched. Unlike other industrial by-products rice husk ash has to be produced out of the raw agricultural waste, husk. The increasing demand for producing durable construction materials is the outcome of the fast polluting environment. Supplementary cementitious materials prove to be effective to meet most of the requirements of durable concrete. In the present experimental investigation M40 grade concrete has been chosen as reference concrete specimen. Cement was partially replaced by granite powder with 10%, 15%, 20%, 25%, 30% and Rice husk ash was partial replaced by 5%,10%,15%,20%,25% and also in the combination of Granite powder and Rice husk ash was also partially replaced by cement in concrete. Compressive strength (cubes) was compared those of concrete made with natural aggregates. specific gravity of the materials was also studied .The test result indicates that it is possible to manufacture concrete containing with granite powder and rice husk ash with characteristics similar to those of cement concrete provided that percentage of granite powder and Rice husk ash is limited to 15% and combination of Granite powder and rice husk ash is partially replaced by cement is limited to 10% and 15% respectively.

An operating systems working framework carries amazing advantages to PC programming and programming improvement. Without a working framework, each application would need to incorporate its own UI, just as the complete code expected to deal with all low-level usefulness of the basic PC, for example, plate stockpiling, network interfaces, etc. Considering the huge swath of fundamental equipment accessible, this would incomprehensibly swell the size of each application and make programming improvement impractical. The OS recognizes and arranges physical and intelligent gadgets for administration and normally records them in a normalized structure, for example, Windows Registry. Gadget makers occasionally fix and update drivers, and the OS should refresh them to guarantee best gadget execution and security. At the point when gadgets are supplanted, the OS additionally introduces and arranges new drivers. A working framework is answerable for recognizing the right printer and introducing the fitting printer drivers so an application needs to just settle on decisions to the printer without utilizing codes or orders that are explicit to that printer that is the working frameworks activity.

In this modern era, most of the buildings all over the world are made up of RCC. The increasing incidents of fire in buildings have increased the importance of assessment; repairs and rehabilitation of such buildings as these buildings are very costly. This field needs special expertise in many areas viz. concrete technology, structural engineering, material testing, and repairs and maintenance etc. A continuous effort through research and development programmes all over the world is being made in this specialized field. This topic gives us immense pleasure as we deal with the real life problems in this research. In this research, we gain the knowledge which is being used as a strategy for the rehabilitation of fire damaged buildings and by conducting proper assessment procedures by non-destructive techniques. In this research, we did various experiments so as to find out the effect of fire on the reinforcing bars in RCC buildings by taking 6 samples at 110°, 310°,610°,900° each for 3 hours. After heating the samples, they are cooled quickly by quenching in water and normally by air cooling. It is seen that there is a change in the mechanical properties of samples which are studied under universal testing machine (UTM) and for close look at reinforcing bars in a fire damaged structure, scanning electron microscope (SEM) is used. From conclusions, it is seen that most of the fire damaged RCC are restorable. The mechanical properties of all common building materials decrease with the elevation of temperature. The behavior of a RCC in fire conditions is governed by properties of constituent materials, concrete and steel at high temperature. Both concrete and steel undergo considerable change in their strength, physical properties, and stiffness by the effects of heating. It is also seen that above 900°C some of these changes are not recoverable after subsequent cooling.

It is known that cement possesses the property of adhesion and is a substance that can fuse with other materials to solidify and get stiffen even independently. During ancient times, the binders used were of conventional type, such as sugarcane byproduct, silica dust, residual ash, to name a few. In the present world, cement is the main folder material. Aggregate generally represents 75% to 85% of the volume of concrete and this mainly consists of fine aggregate and coarse aggregate, though it is generally considered inert filler, which has little impact on the properties of the finished concrete. The proposed work is primarily aimed at improving the strength and durability properties of cement while maintaining the ecological balance. Therefore, utilizing the fact that when factory made derivatives such as silica dust, residual ash, and furnace steel residue derivatives are being used to fabricate an exclusive mixture of concrete mixes, for the early fabrication of high-capacity concrete, the percent rate of substitution is ideal for dual and ternary mixes. In addition to binary and ternary combinations to find out the bending properties of high capacity reinforced concrete beams, it can also be used with supplied factory made derivatives. The proposed research work utilizes the aforementioned ingredients that supply methodical and monetary payback, along with enhancing the strength and durability characteristics of concrete. The results seem to be very encouraging in case of SFC1, RAC1 and SSAC1 with 4.68, 1.53 and 13.68 % outperforming the other CC blends.
