Those essential destinations are to make a quality task, finished on schedule, inside spending plan, and in a protected workplace. In this investigation, I am contrasting a working undertaking and a recently finished task of same perspective, where we picked Nahar Industry new square, mandi deep, Bhopal, which is very nearly execution. Arranging, planning and asset assignment is finished utilizing venture the board instrument Primavera P6 8.3. From the investigation it is discovered, how the task is arranged, the succession of work and connecting connections between exercises for the entire venture. In end, it is gotten that, it is imperative to understand that there will be changes to the timetable rationale just as contrasts between the arranged advancement and genuine advancement. In view of the distinctions, the timetable should be ch...

Seagrass provide habitats for fish and invertebrates, provides food, purifies water, stabilize sediment so its sustainability needs to be maintained. Due to human activities like sewage input, dumping of solid waste on the shoreline and anchoring of boats, the population of seagrass has been decreasing continuously which has led to instability in the marine ecosystem. Maping and classifying the seagrass from the remote place and from satellite image is very complex task. Because seagrasses are live in the in depths of 3 to 9 ft (1 to 3 m) to at depths of 190 ft (58 m) in the oceans. Remote Sensing is a technique of mapping any place, whithout being making physical contact with that place. So this research uses Andaman & Nicobar’s remotely sensed high resolution satellite image, which has taken from Google Earth. The proposed research paper uses machine learning as a tool for mapping and classifying the Seagrass from ...

However, the search terms may contain sensitive information that must be kept secret from the database holder. Moreover, the privacy concerns apply to the relevant documents retrieved by the user in the later stage since they may also contain sensitive data and reveal information about sensitive search terms. Here privacy in both cases must be preserved. Data Owner privacy must be maintained in term of the documents as well as the keyword for each document uploaded. As for the data user, sensitive information in terms of the search results as wells a search history must be protected. Authors propose a practical privacy-preserving ranked keyword search scheme based that allows multi-keyword queries with ranking capability. The proposed scheme increases the security of the keyword search scheme while still satisfying requirements of both the...

Here represents the technology that proposed the working of robot for Floor cleaning. Households of today are becoming smarter and more automated. Home automation delivers convenience and creates more time for people. Domestic robots are entering the homes and people's daily lives, but it is yet a relatively new and immature market. However, a growth is predicted and the adoption of domestic robots is evolving. Several robotic vacuum cleaners are available on the market but only few ones implement wet cleaning of floors. The purpose of this project is to design and implement a Vacuum Robot for Autonomous dry and wet cleaning application using mop. Vacuum Cleaner Robot is designed to make cleaning process become easier rather than by using manual vacuum. The main objective of this project is to design and implement a vacuum robot prototype by using Arduino Uno, Motor, Ultrasonic Sensor, and IR Sensor and to achieve the goal of this project. The whole circuitry is connected with 12V battery. Vacuum Robot will have several criteria that are user-friendly.

This project focuses on the design and modelling of a 3KW residential PV system connected to a 240V single phase grid. The purpose of this study was to conduct an independent experiment on a photovoltaic system with microinverters, to determine their performance characteristics in shaded and unshaded conditions. The systems have fixed tilt angle and fixed azimuth angle. In order to analyse the performance of the systems, the Energy Yield, Performance Ratio, Capacity factor and Annual Energy have been used. This allowed to obtain reliable metrics even with different Irradiance values and different Peak Powers. In the conventional central inverters, several strings of PV modules are combined in order to achieve the power required from the inverter to operate. Strings are connected in parallel and then these strings are led to the inverter after running several meters of DC cables. These cables are often very thick and as a result are very expensive while at the same time, they add losses to the overall system. On the other hand, AC cables are much less expensive and they have fewer losses. A residential system was designed in SAM using specific weather data. The simulation results supported the fact that micro inverters perform well in both shaded and non-shaded conditions. A significant advantage of Micro Inverters is the avoidance of shading losses and mismatch among different PV technologies which consists a great challenge on PV installations. The String Inverter system produced an annual energy of 4763 kWh in the first year with no shading and 4286 kWh in the first year with shading losses.

The nano-capping of silver onto the Al NRs can concentrate the local electric field within the minimal volume that can serve as hotspots. The average size of the Ag nanocaps was 50 nm. The newly proposed nanoporous Ag capped Al NRs as SERS substrate could detect the Raman signal of rhodamine 6G (R6G) up to 10−15 molar concentration. The significant enhancement in the Raman signal of 107 was achieved for Ag capped Al NRs considering R6G as a probe molecule. Using the developed SERS substrate, we recorded Raman spectra for Escherichia coli bacteria with its concentration varying from 108 colony forming units per ml (CFU ml−1) up to 102 CFU ml−1. All the reported Raman spectra were acquired by a portable handheld Raman spectrometer. Hence, this newly proposed low cost, effective SERS substrate can be used commercially for the onsite detection of clinical pathogens. The 3D finite difference time domain simulation model was performed for Ag capped Al nanostructure to understand the generation of hotspots. The simulated results show excellent agreement with the experimental results. We fabricated uncapped Ag nanorods of similar dimensions and performed the experimental measurements and simulations for comparison. We found a significant enhancement in Ag capped Al NRs compared to the long Ag NRs. The description of the Raman signal enhancement has been elaborated.

Initially, secondary recycled HDPE, acrylonitrile butadiene styrene, and nylon 6 thermoplastic composites were investigated for melt flow index (MFI) according to ASTM D1238 standard. Based on the acceptable MFI, secondary recycled HDPE matrix was selected for second-stage processing on twin screw extrusion (TSE). The final process involves reinforcement of ZrO2 into HDPE matrix by TSE in 60:40 ratio (by weight %) for preparation of feedstock filament (for possible 3-D printing of bearings). The results of the study suggest that for processing of HDPE, 40% ZrO2 composite matrix, 50 r min−1 screw speed, 190°C barrel temperature, and 15 kg applied load are the best setting of TSE (for maximizing the tensile strength of feedstock filament). The results are also suppo...
