 Abstract

The optimal allocation of resources to different project tasks involving different and usually conflicting objectives is one of the recurring challenges for a project manager. The main aim of this research is to optimize the time and cost of a project by analyzing their trade-off. Time cost optimization is one of the main obstacles in project scheduling. This paper proposes a new approach for time cost optimization with fuzzy logic in MATLAB. The project direct cost is altered by difference in resource utilization and Activity duration. The proposed model is formulated using fuzzy theory combining CPM computations, time-cost trade off analysis. By adopting the MATLAB software for ranking process, for each case facilitates obtaining the optimum result. Therefore, through this process now the decision-maker can quite precisely estimate the effect of the project deadline on a total project cost before the submission of a tender. The advantages of the proposed approach are demonstrated through an application example and with an example of the time-cost trade-off analysis.

 Abstract

A Road Traffic Accident (RTA) was defined as accident, which took place on the road between two or more objects, one of which must be any kind of a moving vehicle. The major causes for RTAs in our country are rapid increase in personalized modes of transport, a mixture of slow and fast moving vehicles, lack of road discipline, drunken driving and use of mobile phones while driving. Road traffic accidents (RTA) are increasing in an alarming ways. Globally nearly 1.2 million people killed in RTA during the year 2002. In India every year RTA accounts for over 1,00,000 deaths, 2 million hospitalization, 7.7 million minor injuries and an estimated loss of 55,000 cores or nearly 3 % of the GDP every year. The objectives were to assess the existing level of knowledge regarding road safety measures among high school students at Irwin Christian high school, Kolhapur.To prepare and provide Informational Booklet on road safety measures. A descriptive research design was used for the present study. Samples were selected by using Non- probability, purposive sampling technique. The result indicates that, Among 65 students Majority 47 (72.30%) were between student 15 to 16 years and 17 (26.15%) student between 13 to 14 years and 1 (1.53%) student between 17 and above. Majority of students 43 (66.15%) are male and remaining students (22) (33.84%) are female. Among 65 high school student�s 63 rides a bicycle (96.62%) and 2 does not ride bicycle. Majority of high school students knows to ride a bike (70.76%) and 19 (29.23%) high school students do not know how ride a bike. 24 (36.92%) met with an RTA and 41(63.07%) have not met with any RTA. Majority of high school students 56 (86.15%) are in average category and 9 (13.84%) are in poor category, none of the students are in good category. The knowledge scores distribution with a mean were 19.95, median 21, mode 21, standard deviation 6.35 and range were 11. Study concluded that there is an emerging need to provide information booklet on road safety measure. It is high time we should understand that all the high school students should know the need of road safety measures which will help them to prevent from road traffic accident.

 Abstract

The main aim of the project is to alleviate the water problems by using self-curing concrete. In this project the attempt has been made by the intention of developing the self-curing concrete by using Polyethylene glycol 400 & replace conventional steel by steel fiber. Because when we think about the use of conventional steel it requires more time for construction & skilled labor to apply reinforcement.Also, quantity of conventional steel required is more so, cost of construction of material also gets increases. Hence in order to reduce the labor cost we can replace conventional steel to steel fiber, because it is easy & quicker to apply so it can save time & cost of labor.This have a look at deals use of PEG-400 in concrete with 1% of metallic fiber by means of varying percent of 0%,0.5%,0.75%,1% and 1.25% by weight of cement for M30 mix. The concrete is examined to discover the mechanical properties for 7 days, 14 days & 28 days.

Abstract : Parkway snag location is one of the most testing task continuously for self-sufficient vehicle route System. In India the majority of the individuals are died in street mishaps as opposed to by illnesses. As indicated by an overview close about 45% of people are kicked the bucket in street mishaps in a year. Vehicle crash shirking and snag location framework is one in all the chief basic factors inside the car drove. Inside the present, the greater part of the vehicles empower a ready framework which goes about as a security include for the travelers. During this work, propelled the route framework distinguishes and demonstrates the thing is utilized in self-governing vehicles to sufficiently explore through the path in haze. This method distinguishes the hindrance before of the vehicle, cautions the framework. The camera is utilized to distinguish moving or fixed articles. The LIDAR is encased with this method to registering the space of constant moving and thusly the fixed article. The most work adds to the discovery of obstructions sooner than the vehicle. The caution is given to the framework inside the vehicle with respect to the obstruction before all together that the framework helps in impact evasion. During this work, the space between the vehicle and hindrance is estimated by the LIDAR and article identification is finished by the camera. By melding both these sensor esteems the snag is identified and subsequently the separation is furthermore precisely estimated.

 Abstract

Now a days, everyone is familiar with smartphones including farmers. Mobile phones play indispensable role in daily life of people. Use of traditional methods in farming results slow progress. People can see the advantages of using better approaches to cultivate the crops with the tools and technologies that supports farming are yet to move into agricultural field. Farmers are mainly not aware about the technical advancements in farming and also they are unable to know the rates of the crops and their products they sell. There are also many schemes for farmers which are not known to them. With the emergence of mobile phones and Internet, there is a high potential for giving essential information via this means. Hence, an Android application-AGRIO APP is designed to provide a solution to these problems. We are creating a platform for users which is considered either as a farmer or a customer who uses a smartphone through which they can get the updated rates of crops so that they can buy and sell their products at a rates. This application will have features such as, all the farming related information from the experts and necessary information about different schemes. It also provides a platform to sell crops on profits without marketing, finding the current market rate of crops, identifying the climate conditions, understanding the new methods and showing latest news and information from agricultural authority.

 Abstract

Traditional analog hearing aids is same as simple radio. They can be calibrated and adjusted for volume, bass and treble. But hearing loss is not just a technical loss of volume. Rather, hearing scantiness can intensify sensitivity and reduce tolerance to certain sounds while diminishing sensitivity to others. For instance, digital technology can tell the difference between speech and background noise, permitting one in while filtering out the other. More or less 10% of the world's population suffers from some type of hearing loss, yet only a small percentage of this statistic use a hearing aid. The stigma connected with wearing a hearing aid, customer disappointment with hearing aid performance, and the cost related with a high-performance solution are all causes of low market penetration. Through the use of digital signal processing, digital hearing aid now gives what the analog hearing aid cannot give. It suggests the possibility of performing signal-to noises strengthen, pliable gain-processing, digital feedback reduction, etc. In this paper, the simulation of simple digital hearing aid was developed using MATLAB programming language. The implementation of this configurable digital hearing aid system includes the noise reduction filter, frequency shaper function, and amplitude compacting function. This digital hearing aid system is design to adapt for mild and moderate hearing loss patient since different gain can be set to map different levels of hearing loss.
