Abstract: The proposed work analyses there are many techniques already available for the soft handover region. Here the paper comes up with the new hook replacement technology for mobile receiver in the soft handover region. In our proposal, the receiver receive the signal from all available base station (BS) around the mobile and hooks to the base station which provides proper and strongest path while it comes to the fall of signal to noise ratio below pre-decided threshold level. Receiver compare the weakest hook of path concern with base station and remove it from the currently considerable hooks and with the sum of the strong and proper responsive hooks it creates proper and better group. Then after analysing all the hooks from the group it starts communicating with strongest hook. This paper describes this process in this paper by showing error performance, average no of considerable paths offered by this newly hook replacement scheme which is depend on Mobile Controlled Hand (MCHO). Which is applicable to GSM as well as CDMA (IS-95 and CDMA2000).

Abstract: In this paper, a new efficient syndrome-weight decoding algorithm (NESWDA) is presented to decode up to five possible errors in a binary systematic (47, 24, 11) quadratic residue (QR) code. The main idea of NESWDA is based on the property cyclic codes together with the weight of syndrome difference. The advantage of the NESWDA decoding algorithm over the previous table look-up methods is that it has no need of a look-up table to store the syndromes and their corresponding error patterns in the memory. Moreover, it can be extended to decode all five-error-correcting binary QR codes.

Abstract: By handling the one dimensional partial differential equation with three methods i.e. Adomain decomposition method(ADM), Variation iteration method(VIM) and the New iterative method(NIM) and applied logarithmic and exponential functions as initial condition. A general framework of these methods is presented for analytical treatment of fractional partial differential equation arises in fluid mechanics. The fractional derivatives are described in the Caputo sense. The equation used in this paper is fractional wave equation, fractional burgers equation and fractional Klein-Gordon equation. After comparison of the results, the series of solution are found which is very helpful. The basic idea described in this paper is accepted to be further in use to solve other similar linear problems in fractional calculus.

Abstract: The paper examines the functioning process of wireless communication channel. Queuing system with requests of complex structure and dispatching is used as a mathematic model. The paper provides the algorithm of statistical modelling of the system. The modelling considers the peculiar character where each request consists of a random number of operations with a random continuance.

Abstract: In this paper, Carbon dioxide emission from the liquid fuel supplied in Nigeria by the Nigerian National Petroleum Corporation (NNPC) from 2009 to 2013 is analysed. The CO2 emissions and CO2 emission per capita within the given period are computed and projected emission from 2013 to 2025 made using the greenhouse training equation, artificial neural network (ANN) model and polynomial interpolation method and nonlinear fitting method. The available data from the Nigerian National Petroleum Cooperation (NNPC) is extrapolate from 2013 to 2020 using the polynomial interpolation method and the nonlinear fitting method is utilised to fit the data from 2009 to 2030. It is found that CO2 emission and CO2 emission per capita into the air for Nigeria decreased from 2009 to 2011 but, however, increasing continuously from 2012 to 2025. The increase of carbon dioxide in the Nigerian air space with will pose potential problems in future. Policy must be put in place to reduce carbon dioxide emission by reducing of flaring of natural gasses, introduce electric railways and other energy sources that are based on renewable energy. Enforcement of afforestation and greenhouse gasses emission reduction policies on the country for ecological development. There are other sources of pollution of the atmosphere with CO2 such as flaring of gasses from refineries in Kaduna and Niger Delta areas of Nigeria and burning of bush and burning of solid fuel such as coal in the industries that our research did not cover. These other sources also contribute substantially to CO2 emission in Nigeria.
