1. IoT based fertilizer ratio detection and yield analysis using sensor statistics

The main objective of the project is to predict the NPK fertilizer ratio for plant growth and Yield analysis for various types of plants. For example, rice will be cultivated within 7 to 8 months then it will continue throughout the season. The remaining time the farm will be left empty without irrigation. This leads to loss of soil fertility. Some other crops can be cultivated for the remaining 4 months with less irrigation time thus loss of soil fertility can be reduced. Our process is to install various sensors in the farmland to identify the growth of the plants by analysing atmospheric temperature, humidity in air and moisture in the soil. All these sensors will work together to sense the data and those data will be transferred into PC for algorithm calculation. Analytical methods have been used for the best analysis result. The calculated result will produce various output for all types of soil with the irrigation details and also yield analysis can be calculated with the sensed data. The main aim is to reduce the wastage of fertilizer during cultivation and to increase the quality of the soil. Sensors used are Temperature sensor, Soil moisture sensor, Humidity sensor, PIC Microcontroller. In the proposed system collection of soil testing reports are pre-processed to check whether training data sets are available. The training data sets are subjected to data mining techniques like grouping and clustering methods. Finally, decisions tracked and implemented based on group characterization rules.Here two interfaces will be created, one for admin and another one for the user. Here the admin can upload the dataset for the data analytics process and the user can view all the analysed data by the user-defined input. Now the farmer can predict the cultivation and fertilizer ratio.

2. Health monitoring for coma patients

Internet of Things in “Health Monitoring for Coma Patients” is developed using IOT hardware kit as the transmitter and cloud server as the receiver. A hyper terminal tool has been used for PC interface. The main objective of this project is to develop a web-based application to communicate with an internet server in a secured manner for coma patients. The term net of Things typically refers to eventualities where network property and computing capability extends to things, sensors and everyday things not ordinarily thought-about computers, permitting these devices to generate exchange and consume knowledge with tokenish human intervention. In this project, a Dynamic Service Non-Dependency Verification for comma patients has been implemented using IOT. The first process of this project initiates with a hardware interface. The hardware has been designed using the 8051 microprocessor. All the sensors will be wired over the body of the coma patients. The sensors value will be uploaded in a centralized cloud server. A threshold value will be assigned for each sensor. In case of any abnormal condition, they warn immediately to the user interface end. Secure Service Virtualization in IoT by Dynamic Service Non-Dependency Verification is ensured by the hardware phase initially.

Survey Report

3. Technical survey on cloud computing and its security issues

Cloud computing also referred to as “Cloud” is one of the most growing branches of Computer Science. It has helped in storing and accessing data resources remotely over the Internet. This technology uses shared resources instead of storing resources individually on each computing machine. It offers several benefits such as anytime access, low cost, scalability, convenience, and availability. Despite having many features, cloud computing has some issues too. The most critical issue of Cloud Computing is its security. The security risks and privacy issues are higher when data is stored on individual machines compared to the data stored on “cloud”. These risks have to be considered by customers before moving to cloud service. In this paper, we have discussed the definition of cloud computing, its categories (IaaS, PaaS and SaaS), several clouds computing security issues and solutions against cloud computing security problems.

5. Experimental study of cactus extract on concrete

Natural polymers have been used in ancient times to improve the durability of concrete. The natural polymers used were locally available. We are expecting that cactus extract increase the plasticity and workability. In this investigation, the cactus extract is to be tested in Portland pozzolana cement (PPC). Calcium hydroxide produced by Portland pozzolana cement reacts with the components of cactus extract such as polysaccharides protein & fat and from complexes hence pores are reduced in the admixture modified concrete in comparison to the reference concrete. As the pores are reduced in the admixture modified cement concrete, the compression, flexural and split tensile strength of the concrete will be increased in the admixture modified concrete in comparison to the reference concrete. In this project we choose M30 grade of concrete and grade of cement is 43 for that we use 20 mm aggregate which is passed through the 20 mm sieve and also which are passed through 4.75mm sieve as a fine aggregate we decide to make cube and also cylinder , cube for compression test adding cactus extract 10%,15%, and 20%with water totally 15 cube we will be going to make 12 cubes for compression test and 3 cubes for self curing because the cactus having high water absorbing character and also it will absorb water from atmosphere and cylinder for split tensile test, here also 12 cylinders from those concrete 7 days 14 days and 28 days strength we will calculate. The cactus extract is used as a natural organic admixture in concrete It is seen that cactus extract improves the plasticity of the mortar, workability and compressive strength of the concrete Naturally cactus having water absorption character so we also make a test for self-curing in concrete.

6. Study on investigation of behavior of concrete by replacing the ceramic waste and rubber tyre waste

Ceramic waste is one of the most active research areas that encompass a number of disciplines including civil engineering and construction material. In this research study, the cement has been replaced by ceramic waste powder accordingly in the range of 0%, 10%, 20% & 30% by weight of concrete. The discarding of waste tyres is a serious concern all over the world as it causes environmental problems. Our main aim was to utilize the waste tyre rubber in concrete as a partial replacement instead of coarse aggregate. Tyres cut into pieces with a maximum size of 20mm to use as coarse aggregate in concrete. The use of waste tyre rubber chips in concrete makes it economical and moreover, it becomes environmentally friendly. The strength of concrete with partial replacement of waste tyre rubber at various percentages had been investigated carried out for three different percentages of rubber tyre say, 0%,5%, 10% and15% at 7 days curing period.

7. Comparative study of skew slab bridges using Grillage analogy and Finite element method

Presently constructed bridges are often skew. The configuration of such a structure is the result of natural or man-made obstacles such as complex intersections, space limitations, and/or mountainous terrains. Gravity loads in many skew bridges take a different path towards the support than right bridges. In skew bridges, this brings about significant torsion moments near the obtuse corner, changes in longitudinal as well as transverse bending moments and changes in support reactions. In this present study, a solid slab bridge deck studied using grillage and finite element method. The effect of different skew angles on same-span of reinforced concrete bridges using the finite-element method and the grillage analogy method is compared. Maximum and Minimum reactions forces, deflections, Bending moments in the central strip and edge strip calculated and compared for both analysis methods. A total of twenty different models prepared, five for each method on skew angles 00, 150, 300, 450 and 600 with rigid supports. The supports then changed to elastomeric bearing supports to compare the change in hogging bending moments. The prototype chosen for comparison is 11m long and 12m wide deck slab without footpath but with edge beam. The slab thickness chosen is 800mm. The longitudinal members aligned along a square direction so that reinforcement can be calculated directly without the need for resolution. The grillage properties are given as per book by E.C. Hambly and FEM elements modelled as per book by G. A. Rombach. It is observed that the finite element method (FEM) and Grillage method yield similar results and in a few cases FEM gives lesser results. Bending moments calculated by using grillage analogy method overestimates the results obtained by the FEM method.
