 Abstract

This paper reports an experimental study on the fabrication and parametric evaluation of non-woven textile material prepared from uni-fiber natural material. The test parameters on which these fabrics are evaluated are Thickness, Grams per Square meter (GSM), Air permeability, Mechanical properties, Pore size distribution, and Moisture Absorbency. These parameters have been studied and discussed for three types of non-woven fabrics, namely Sisal (100%), a blend of Sisal (70%) and Coir (30%), and a blend of Coir (70%) and Sisal (30%). Sisal (70%) and Coir (30%), blend has greater Air permeability and Bursting strength were specific treatment should be given for the material for future application such as noise control, sound proof lamination board, air conditioning, RCC curing material. The use of inexpensive and abundantly available raw materials to prepare a value-added product has been the aim of this study. The physical and chemical properties of fiber study and tangle of fiber by using web method process sisal 30%and coir 70% intrinsic lower air permeability and good in busting strength. Developed nonwoven fabrics using needle punching method can be converted as house hold wipes, geo textiles, mattress, and in agriculture. Specific treatment should be given for the material for future application such as noise control, false roofing material, printing, embossing wall hangings.

ABSTRACT: Schiff bases(BNTM,BCTM,BMOM) derived from 2-aminomethyl benzimidazole.2HCl and The metal ions proposed for the work include Mn(II), VO(II), Co(II), Ni(II), Cu(II) and Zn(IThe new Schiff base and the complexes were tested for in vitro antibacterial activity against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa using diffusion method. The Schiff base and the complexes exhibited varying degrees of inhibitory effect on the growth of the tested bacterial species. The values reveal that the Schiff base became more effective when coordinated to the metal ions. Among all the metal complexes, Co(II)-BNTM exhibited higher inhibitory effect on the growth of the tested bacterial species.

 Abstract

In rural and urban parts of India, burnt clay bricks are extensively used for housing purpose. Clay is obtained from agricultural land and bricks are manufactured from this clay. Overuse of clay cause loss of fertile soil and divert agricultural land for the purpose of brick manufacturing. It may be possible to produce clay bricks by replacing some percentage of conventional soil by Waste Foundry Sand and some percentage by Flyash.

Abstract -- In this paper, a compact frequency reconfigurable antenna is presented for WLAN applications. The proposed antenna consists of a partial ground, tuning fork shaped patch and two PIN diodes are integrated at the two corners of forks to obtain frequency reconfigurability. A 50-ohm microstrip line is used to feed the antenna. FR-4 epoxy substrate is used in design with dielectric constant 4.4 and loss tangent 0.02. The total size of antenna is 21mm x 13mm. The proposed antenna design and simulation carried out using HFSS Simulator. The proposed antenna is having two PIN diodes to provide multiple frequency bands in the range of 4-8 GHz. Using two PIN diodes three possible conditions are achieved. The proposed reconfigurable antenna can switch at multiple operating frequencies i.e., 5.14 GHz 8.60 GHz (both diodes ON), 4.57 GHz, 5.74 GHz (one diode ON and other diode OFF), and 5.86 GHz (both diodes OFF) based on conditions provided by PIN diodes. The antenna shows good characteristics at every operating frequency. The proposed antenna can work effectively for C-band applications.

 Abstract

This paper presents the design and the development of an interactive multimedia futuristic Smart Mirror for commercial uses in various industries. The project which would collect real world machine data and the data would be transmitted from the machine and would be managed by the Raspberry Pi. The Smart Mirror implemented as a personalized digital device equipped with peripherals such as Raspberry PI, microphone, buzzer , LED Monitor covered with a sheet of reflective one way mirror provides one of the most basic common amenities such as weather of the city, latest updates of news and headlines and local time corresponding to the location. A screen is placed behind a two-way mirror 1. By using a black and white graphical user interface (GUI) only the white colors will penetrate the mirror, resulting in an effect that makes it appear as if the mirror itself is a screen. Our lifestyle has evolved in such a way that optimizing time is the most important thing. Based on the user studies and prototype implementation, we present the development of an different application that integrate interactive services of information, offered through a user interface on the surface of a mirror. Our work is based on the idea that we all looks at the mirror when we go out, so why wouldn't the mirror become smart. The framework will offer basic services, like the presentation of personalized weather data, time, date and will incorporate some additional functionality, like reminder service by mobile synchronization and through social media. Our framework is based on detecting presence of human using Passive Infrared sensors and Wi-Fi connectivity. Once a person comes in front of the mirror, it displays the information that is being fed from the phone. This data or information includes calendar, time, weather, news feed, notifications and so on. Our framework also discusses about the face recognition and its application in control mechanism in home appliances and opening and closing of shelf. Our framework also introduces speech activated music player, and plays the music when a person gives a command.
