This paper deals with in developing an inventory model for time dependent decaying items as bread, food stuff, green vegetables and medicine etc. The rate of deterioration is time dependent and considers a linear function of time. Demand rate is stock dependent in linear form. It is a common phenomenon observed in the super market that a large pile of goods attracts more customers. Shortages are allowed and shortages are completely backlogged. The numerical example is given to illustrate the model developed. The model is solved analytically by maximizing the total profit. KeywordsInventory, EOQ Model, deteriorating items, stock dependent demand rate

Among various diseases cancer has become major threat in India. As per Indian population due to cancer the mortality rate was very high. Cancer is the second most disease responsible for death in India. In view of these facts, this paper will reviews that how CT scan screening technology is helpful for cancer prevention in early stages. In the end this paper will also discusses which techniques has to be adopted for better accuracy of cancer prevention system.

Throughout this study, a novel network model for massive machine-type communications (mMTC) is proposed using a compressive sensing (CS) algorithm and a non-orthogonal multiple access (NOMA) scheme. Further, physical-layer security (PLS) is applied in this network to provide secure communication. We first assume that all the legitimate nodes operate in full-duplex mode; then, an artificial noise (AN) signal is emitted while receiving the signal from the head node to confuse eavesdroppers (Eve). A convex optimization tool is used to detect the active number of nodes in the proposed network using a sparsity-aware maximum a posteriori (S-MAP) detection algorithm. The sensing-aided secrecy sum rate of the proposed network is analyzed and compared with the sum rate of the network without sensing, and the closed-form expression of the secrecy outage probability of the proposed mMTC network is derived. Finally, our numerical results demonstrate the impact of an active sensing algorithm in the proposed mMTC network; improvement in the secrecy outage of the proposed network is achieved through increasing the distance of the Eve node.
