Performance of tcp and udp protocols for secure multipath aco communication in manet

The ACO (Ant Colony Optimization) isnovel concept to improves the routing performance of network because multiple choices of path available to deliver data to destination. The link capacity in network is limited and it is also not possible extend easily as wired network. The multipath protocol like AOMDV is balance the load by providing alternative path but not proficient at every condition. The problem of congestion in MANET is not possible to removes completely because of limited bandwidth capacity of link between the two nodes.

A conseptual approach to the implications of brexit on the social-economic aspects into the uk and the European Union

The purpose of this paper is to examine the effects of Brexit on social-economic aspects into UK and the European Union as well. It is mentioned that for the first time in a generation there is a serious prospect of a member state leaving the European Union. In Britain, the Conservative government, led by Prime Minister David Cameron, is committed to holding an in-out referendum by the end of 2017. If the UK leaves the EU the impact would depend on the new relationship between the UK and the EU. We consider five models.

Development and evaluation of taste masked clarithromycin oral suspension

Most  of the pharmaceuticals  are  administered  by  the oral route which is the  popular  route  of  drug  delivery. Taste is an essential and critical parameter in administering formulations which have relation with taste buds. Several drugs have bitter taste, consequently there is  a consistent  problem in the treatment of  the  patients  because of their inability to swallow such formulations.

Application of ahp method in the formation of a performance indicator for operational level professionals

The studied company is a major insurer that has experienced some operational problems due to an imbalance between the evaluation criteria of employess in the regulation sector of car accidents. The company evaluates each employee according to four indicators: cost, efficiency, productivity and professionalism. However, the scores of these criteria are aggregated in the form of a simple arithmetic mean, which does not align with the company’s strategic planning.

Solving lte handover problem using a new fuzzy logic optimization technique

In cellular networks, the contradiction between traffic demands and network resources is very prominent, also mobile users can move inside the heterogeneous networks from cell to another cell. Aiming at solving these issues, efficient handover (HO) mechanisms are more and more concerned to enhance mobility management. In this paper a new handover optimization algorithm for long term evaluation (LTE) network based on fuzzy logic is presented, named Fuzzy Logic for LTE Handover (FLLH).

Design and fabrication of self aiming and engaging gun (Saeg)

This project involves the complete system design and construction of a SAEG to replace an armed guard. We aimed to develop a compact and highly mobile defence system that allows operational flexibility. The SAEG can autonomously track and shoot at moving targets, while also allowing a user to remotely access and control the gun via computer. The mobility, hardiness, and functionality of this system allows a reliable replacement for human beings in harsh and hostile environments; ultimately sparing a life.

Experimental investigation on thermoelectric generator system for performance enhancement

Experimental Investigation on thermoelectric generator system consisting couple of Thermoelectric Generator modules using two different energy sources, one is solar water heater and the other is gas cartridge heating torch is carried out. Solar energy is used to heat the water through solar water heater to supply heat at the hot side of Thermo Electric Generator (TEG) creating the temperature difference for power generation. This concept is suitable for hot atmosphere like summer season in India, solar radiation is high.

Perovskite solar cells: a quantum leap in solar research

Organic–inorganic metal halide perovskites are recently proved to be suitable candidates for application in solar cells. Devices made of perovskite show efficiencies from 3.8% in 2009 to National Renewable Energy Laboratory (NREL) certified efficiency of 22.1% in 2016 making this the fastest-advancing solar technology to date. CH3NH3PbI3 and CH3NH3PbI3-xClx are currently the front-and-center materials for high efficiency perovskite solar cell.

Worrying and real risk for human papilloma virus-induced cervix lesions in cameroonian women: insight in a socioeconomically disadvantaged Muslim region

Cervical cancer is a real public health problem in developing countries especially in socioeconomically disadvantaged populations which are often very difficult-to-reach by health programs and mistrustful about these. We therefore carried out a pilot hospital-based cross-sectional study in the far north region, one of the poorest regions of Cameroon. This aimed at determining the prevalence of cervical pre-malignant and malignant lesions and of some main risk-increasing factors. Socio-demographical and risk factors for cervical abnormalities were documented.
