This research is aimed at developing a traffic model that will predict a blocking probability for voice calls and handover calls blocking probability in mobile communication networks (GSM). The high number of block calls experience in mobile network, especially during the busy- hour as leads to poor Quality of Service (QOS) delivering in mobile network. The block calls experience in mobile network should be reduced (in line with NCC recommended value 2%) to a certain low values, to ensure good QOS. The developed traffic model is focused on new voice calls and handover calls in a cell. The developed traffic models are designed based on the number of channels resource available; these numbers of channels are partition into two segments in a cell network. The cell technology is homogenous in nature; therefore it is applicable to the entire mobile communication system. The analytical method is deployed, and the collection traffic data with equipment know as the Operation and Maintenance Center (OMC-counter) which is in built in the mobile communication network. The OMC-counter runs on Linux operation software, which helps to capture the number of arrival calls and service time in a specified interval. The arrival rate is assumed to be Poisson and the interarrival rate (the different between two arrival points or more) is also, assumed to be exponentially distributed and independence identical distributed. These parameters were assumed in the developed traffic model. The developed traffic models are blocking probability for voice calls and handover calls are shown in Equation (3) and (4). These traffic models are used to manage, a balance relationship between cost incurred in mobile communication by operators and service render to the mobile subscribers.

Ajayi","doi":"10.7176/cti/8-03","DOIUrl":"https://doi.org/10.7176/cti/8-03","url":null,"abstract":"A simulation approach for the assessment of variables interaction and consequent control structure selection of a fluid catalytic cracking unit (FCCU) is presented in this paper. The simulator which was implemented in Matlab draws from an earlier mathematical model of the FCCU, was used as a virtual FCCU for studying the dynamic response of the riser temperature (T rx ), the regenerator temperature (T rg ) and the regenerator flue gas oxygen concentration (O d ) to step changes in air flow rate (F a ), regenerated catalyst flow rate (F rc ), gas oil feed rate (F gr ). The results show strong interaction in FCCU variables, with F a affecting T rg and O d ; F rc affecting T rx, T rg and O d ; F gr affecting T rx , T rg and O d . A linearised state-space model based on the first-principle model was deduced and transformed to a 3x3 input-output model. Three channel interaction measures: Relative Gain Array (RGA), Effective Relative Gain Array (ERGA) and the Normalized Relative Gain Array (RNGA) were applied to the selection of FCCU control structure. All the measures point to a diagonal scheme with the following pairings: (T rx /F gr ), (T rg /F a ) and (O d /F rc ) ,for the decentralized control of the riser temperature, the regenerator temperature and the flue gas oxygen concentration respectively. The suggested control structure offers a high promise of stability, with a Niederlinski index (NI) of 101.79.

Adehi","doi":"10.7176/cti/8-02","DOIUrl":"https://doi.org/10.7176/cti/8-02","url":null,"abstract":"The need for fast, efficient and simple scanner generator that has the primary responsibility to perform efficiently gave rise to this paper. This is due to the fact that, on daily basis new technologies arise which brings a great improvement on the design of computer architecture. However, attention was given to speed, run time and resource availability of the design machine to be used since lexical analysis has an impact on how the compiler works. This paper seeks to develop a lexical analyzer (scanner generator) automatically by specifying the lexemes patterns to a lexical analyzer generator and compiling those patterns into a code that functions as a lexical analyzer. The scanner accepts characters as input and breaks them down to produce tokens by grouping the characters and not deviating from specifications. The project employs one of the different methods of lexical analyzer generator to perform pattern-matching on text using regular expression over a global character set. The paper shows how input is matched and specifies what to do when a pattern is matched. This was achieved with the use of regular expressions (RE) which were converted to non-deterministic finite automata (NFA) or deterministic finite automata (DFA). The regular expression and the regular grammar were thus joined together mathematically. Various results are presented and further work on micro compilers was proposed.

In this paper, we propose a novel hexapod robot design which involves the incorporation of a rotary encoder-embedded weight-bearing wheel to relax the stringent limitations on the choice of the robot’s joint actuator torques and the battery capacity. The results of the prototype implementation showed that our design inherits the merits of easy linear distance measurement via the embedded rotary encoder, low actuator torque and high payload capability from wheeled robots.

The kingdom of Saudi Arabia  (KSA) faces an acute water shortage due to arid climate and absence of permanent lakes and rivers. Ever-increasing imbalances are usually met by increasing water supplies, whereas the concepts of water-demand management have not been given due importance and weight age. Meeting the rapidly rising demand with scarce and depleting resources remains the critical issue. The main goal of this paper is showing; how Geographical Information Systems (GIS) can be used to support infrastructure  of demand water and waste-water. This paper places emphasizes on the urgency of adopting conservation and water-demand management initiatives to maintain demand supply relationship and achieve an acceptable balance between water needs and availability. Demand for water and waste-water infrastructure projects has remained  unaffected by the global financial crisis, and it continue to grow exponentially. Waste-water is a rapidly and globally expanding area of infrastructure development, that enables the sustainable re-use of scarce water resources for non-potable purposes in industry, agriculture, and greening. particularly in the agricultural sector-the largest and most inefficient user of water have been suggested. The paper suggests that the water-use-efficiency (WUE) in various sectors can be enhanced and improved in a local area of the kingdom of Saudi Arabia. The objective of this paper is to safeguard and conserve this precious natural resource through environmental enhancement  technologies for the future generations to come. It is presumed that water resources can be managed on sustainable basis by devising and employing environmental technologies including water conservation measures and develop water for sustainability and efficiency. To improve governance and management to the highest level. Provide water service to the Saudi people up to the level of developed countries whilst minimizing the fiscal burden. To develop and introduce technological and institutional innovations. To conserve and improve the environment.  The usefulness of these measures can be supplemented through the vibrant and viable extension and education initiatives and capacity building programs.
