A survey on door access security control system via Raspberry Pi
In this paper, a control system for the door is being developed. A drastic growth and an increasing trend have been seen in the field of home automation control system. The person identification system is used as the basic design for the door control system. This technology is mostly preferred because of its enhanced security and the accuracy in the recognition of the individual. The main advantage of this system is that it can be accessed or controlled from any location in the world. At first, the images of the authorized individuals, for example, a particular family consisting of 7 or 8 members are being captured and made to store in the database. If the authorized person is not available at home and in case a third person or a visitor wants to visit his/her house, the system first captures the image of the visitor and compares it with the image stored in the database. If the match is found, then the person will be given access inside a house with door unlock. If the match is not found the access is denied and the alert notification is sent to the owner’s registered mail with the image captured. Then the owner decides to either provide access or deny it.

Productivity enhancement of pentagon type solar still and dryer in series using biomass energy
Desalination alludes to the methodology of expelling salt and different minerals from water. Water is desalinated with a specific end goal to change over salt water to new water so it is suitable for human utilization or watering system. In this paper, a novel design of pentagon still was designed and operated along with dryer using biomass energy to increase the productivity of desalination and drying efficiency of the dryer at THE same time. The basin plate of the conventional still was modified with wide area and double slope covers at the top to act as pentagon still the single basin dryer was operated in series. A biomass heater was connected in between these two to supply heat. The Pentagon still was operated with different depths of water, energy storing, exposure materials to strengthen its production. A heat exchanger was attached at the basin plate with extended surfaces to circulate heat. A conventional still was operated in the solar mode in the same location to compare the performances with modified still. Solar dryer was used to dry pineapple with the waste heat from biomass heart source. The productivity of pentagon still was 29%, 47% higher than conventional still when operated in solar, biomass heated modes. Addition of energy storage, exposure materials strengthen the productivity by 47%, 48%, and 41% respectively, adding extended surfaces in heat exchanger improves 20% in production. The drying efficiency was good in biomass mode when compared to solar mode. The payback period for the Pentagon still was very less. The energy balance for the boiler was also performed.

Geolocation using NodeMCU
Geolocation is defined as the identification/estimation of the real-world geographic location of an object, such as a radar source, mobile phone, or Internet-connected computer terminal or any other device. Apparently, geolocation involves the generation of a set of geographic coordinates and is closely related to the use of positioning systems, it is enhanced by the use of these coordinates which determine a meaningful location, such as specific area. In this project, we will be interfacing a GPS module with NodeMCU. A simple local web server is created using NodeMCU and the location details are updated in that server webpage. NodeMCU is an open source IoT platform. It includes firmware which runs on the ESP8266 module and hardware which is based on the ESP-12 module. ESP8266 can be used for geolocation by firstly obtaining nearby AP properties, and then using Google geolocation API to locate the user-device. To be able to obtain a fix on the location of the device that integrates the ESP8266 chip, we assume that the host controller first could obtain data from nearby Wi-Fi networks or cellular sub-systems. The data is consolidated into a data block that must be sent to an online geolocation API or service that will estimate the device location in terms of latitude, longitude, and accuracy.

Design improvements in heat exchanger using partial differential equations
In today’s world, where the loss of energy due to engineering applications is increasing at an alarming rate, therefore efficiency is much needed in order to save the energy. The aim of the paper is to propose a new design of heat exchanger which would result in a substantial increase in the efficiency of the heat exchanger. The basic principle used to increase the efficiency is to change the shape of the tube holding fluid. In this paper, instead of using conventional cylindrical tubes for heating fluid, a cone-shaped tube with cold fluid entering the pipe through the base end and hot fluid coming out of the vertex end is used. This is achieved by tweaking the surface area to volume (SAV) ratio of the fluid carrying tubes. Since the Gaussian curvature through the axis of the tubes is zero, it’s a Euclidean surface. Thus there will be no change in properties if the conical tube is bent in the form of a helix. For a given volume, the object with minimum SAV ratio is a sphere as a consequence of isoperimetric inequality in 3 dimensions. Efficiency can be further increased by bending the shape of the tubes in form of a spherical helix. This would create a central heat source and constant temperature at the contact surface. Therefore there is a gradual decrease in volume as we go from base to the vertex of the conical tube would mean that pressure of hot fluid would increase as temperature and degree of freedom is constant.

Collection of data through cookies and smart devices – A case study
Data is everywhere. Ubiquitously, companies and governments are collecting data. One simple visit to the world wide web leaves a wide digital footprint. One Google search about the best mutual funds in the market and you will be bombarded with mutual fund advisories anywhere you visit. The lines between the online world and the offline world are blurring, as the number of metadata increases. This paper looks at certain ways as to how our civilization is becoming smarter, with every device around us right from the mobile phone to electric bulb, becoming smarter with each passing day. This paper looks at the origins of the collection of metadata, as well as their use in customizing the world as per our needs and wants.

Study on strength and initial surface absorption of concrete using recycled steel fiber
Experimental investigation on Re-using Steel Wire from Tyres for Fibre Reinforced concrete was carried out by researchers. Steel Fibres are most popular metallic fibers used for the production of Steel Fibre Reinforced Concrete particularly from the point of view of strength and ductility in the present experimental investigation, attempts are made to study on the various strength properties like compressive strength, split tensile strength, an also durability properties ISAT test was held on long-term durability properties of tire steel fiber. Experiments were conducted for both Ordinary Concrete and steel Fibre Concrete with different percentages It was observed that as the addition of waste tyre steel fibers to concrete mix increases, the workability of the concrete mix was found to decrease as compared to control mix. At an optimum dosage of WTSF, the increase in compressive strength of glass fibre concrete mixes compared with control mix. The percentage increase of split tensile strength of WTSF concrete mixes compared with control mix by weight of the binder. The addition of waste tyre steel fibers into the concrete mixture marginally improves the compressive strength at 28 days. It is observed from the experimental results and its analysis, that the compressive strength of concrete, splitting tensile strength of concrete increases with the addition of 1% Percentage of waste tyre steel fibers.
