Most impressive features of mobile cellular communication network are frequency reuse and handover. In any cell two types of arrival, new originating call and handoffcallfrom surrounding cells.These two arrivals follow two different types of traffic hence any cell in network experiences mixed traffic. This paper will deal with mixed traffic of a cell based on Markovian chain with numerical example. Finally mathematical expression of Probability State and call blocking is derived from two-dimensional state transition diagram to validate the result.

A new optimized bowl-shaped mono-core surface plasmon resonance based cancer sensor is proposed for the rapid detection of different types of cancer affected cell. By considering the refractive index of each individual cancer contaminated cell with respect to their normal cell, some major optical parameters variation are observed. Moreover, the cancerous cell concentration is considered at 80% in liquid form and the detection method is finite element method with 2 100 390 mesh elements. The variation of spectrum shift is obtained by plasmonic band gap between the silica and cancer cell part which is separated by a thin (35 nm) titanium film coating. The proposed sensor depicts a high birefringence of 0.04 with a maximum coupling length of 66 μm. However, the proposed structure provides an optimum wavelength sensitivity level between about 10 000 nm/RIU and 17 500 with a resolution of the sensor between 1.5 × 10 −2 and 9.33 × 10 −3 RIU. Also, the transmittance variance of the cancerous cell ranges from almost 3300 to 6100 dB/RIU and the amplitude sensitivity ranges nearly between −340 and −420 RIU −1 for different cancer cells in major polarization mode with the maximum detection limit of 0.025. Besides, the overall sensitivity performance is measured with respect to their normal cells which can be better than any other prior structures that have already proposed.

This paper is an attempt to identify various agency relationships that may exist in the economic & business life & the related problems that may arise due to such relationships. Corporate governance is a burning issue now a day. We have witnessed a paradigm shift in the corporate governance practices in different countries where audit committee has been addressed and accepted as a striking force. Likely, audit committees in the corporate sector in Bangladesh have a formidable challenge of effectively overseeing the company's financial reporting process in a dramatically changed but improperly regulated or unregulated corporate governance environment. It is also an effort to make a relationship between mitigating the agency problem and the role of audit committee in this respect. .

In this paper we consider a local area network (LAN) of dual mode service where one is a token bus and the other is a carrier sense multiple access with a collision detection (CSMA/CD) bus. The objective of the paper is to find the overall cell/packet dropping probability of a dual mode LAN for finite length queue M/G/1(m) traffic. Here, the offered traffic of the LAN is taken to be the equivalent carried traffic of a one-millisecond delay. The concept of a tabular solution for two-dimensional Poisson's traffic of circuit switching is adapted here to find the cell dropping probability of the dual mode packet service. Although the work is done for the traffic of similar bandwidth, it can be extended for the case of a dissimilar bandwidth of a circuit switched network.
