 Abstract

Urban areas around the world are populating their streets with Vehicular Ad Hoc Network (VANET) in order to feed incipient smart city IT systems with metropolitan data. In the future smart cities, VANET technology will have a massive presence in the streets, and the operation of municipal services will be based to a great extent on data gathered with this technology. However, from an information security point of view, VANET can have failures and can be the target of many different types of attacks. The ability to route the packet to the next node is the foremost requirements of such vehicular networks. One of the main issues to be addressed in VANET is congestion. When a sudden burst of traffic is detected, the nodes need to forward it towards the destination. The node that is forwarding may also have some packets to be delivered from it. The outgoing packets and transitory packets lead to buffer overflows at a node which in turn lead to packet drops and finally degrades the overall network performance. Congestion control schemes are essential in such situations to increase network performance and ensure a fair use of the resources. This work proposes a congestion control scheme distributed across the transport, network and MAC layers that can detect and avoid congestion in the network. It provides priority based traffic scheduling with a dual queue scheduler which favors transitory packets. When congestion is detected based on the buffer occupancy, source sending rate is updated by the sink periodically with the help of dual queues and route the packets through less congested paths.

 Abstract

Everyone is in communication with the others in the social setting, which is a trait of socially defined persons. Individuals should trade and discuss views, news, and other information, in other words, they should communicate. Anything that inhibits us from receiving and understanding the messages others use to communicate their information, ideas, and thoughts is referred to as a communication barrier. Attitudinal Hurdles, Behavioural Barriers, Cultural Barriers, Language Barriers, and Environment Barriers are the five categories of barriers to effective communication. People with diverse attitudes, values, and prejudices are a common cause of workplace communication breakdown. In this regard, it is more important than ever in organizations where formal and informal communication coexist.

 Abstract

Diabetes mellitus is becoming a common metabolic disorder which has serious threat to public health in the world. There are chemicals and biochemical agent that helps in controlling diabetes but there is no permanent remedy available which helps to get recovered completely from this disorder. By conducting large number of research work, numerous traditional medicines have been found for diabetes. Substances and extracts isolated from different natural resources especially plants have always been a rich arsenal for controlling and treating diabetes problem and complication arising due to it. So this review helps the reader to understand the importance of various types of herbal and polyherbal formulations present traditionally which can be used to treat diabetes mellitus.

 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.
