The slack-based measure (SBM) DEA model is a non-radial model used to calculate the relative efficiency, input, and output targets of the different decision-making units (DMUs) based on their best peers or efficient frontier. ...

Data Envelopment Analysis (DEA) is a multi-criteria technique based on linear programming to deal with many real-life problems, mostly in nonprofit organizations. The slacks-based measure (SBM) model is one of the DEA model ...

We propound a descent principle by which previously constructed equations over GF.qn/.X/ may be deformed to have incarnations over GF.q/.X/ without changing their Galois groups. Currently this is achieved by starting ...

Difference sets are subsets of a group satisfying certain combinatorial property with respect to the group operation. They can be characterized using an equality in the group ring of the corresponding group. In this paper, ...

Recently data broadcast has emerged as powerful tool for information dissemination to massive number of clients equipped with portable gadgets. Wireless communication use air as medium for transferring data to exchange ...

The supply chain inventory planning is well studied and analyzed in the literature considering various costs and other factors. However, social factor is largely overlooked although, it is important like cost factors which ...

In this paper, we study (N, L) switch-over policy for machine repair model with warm standbys and two repairmen. The repairman (R1) turns on for repair only when N-failed units are accumulated and starts repair after a set ...

In this paper the subrating channel assignment scheme is used to improve the performance of handoff packets. The subrating of a channel is done by dividing temporarily a full-rate channel into two half rate channels. ...

Due to its widespread application mobile computing has become reality. In real time broadcast, data management research community faces challenge from battery power and delay in data retrieval. The increasing populations ...

With the cutting edge technology advance in wireless computers data broadcast has emerged as powerful tool for information dissemination to massive number of clients equipped with portable gadgets. In such computing system ...
