The littice designs have prove efficient but they are not alwasy available. This article proposes an alternative, an almost lattice design, of the triple lattice design (v=36, k=6, r=4) which is not available. Here, we compare the almost lattice design to the .alpha.-design (v=36, k=6, r=4) which is another alternative of the triple lattice design (v=36, k=6, r=4). Consequently, we show the almost lattice design is a more efficient alternative than the $\alpha$-design through A-, D-, and E-optimality.

This primary study describes some proposition of restoration and rehabilitation of rail station and station impact area for efficient use. Therefore, I reviewed the functions and roles about rail station and other railway facilities related with urban structures and development, and also analysed the case studies about realignment of rail station, and then, suggested primary management plan of efficient railway installation. This study has some bounds and limits owing to the descriptive reviews but not detailed analyses. Hereafter, I am planning to consider the management plan for efficient railway installation use as coinciding with specific city characteristic and comprehensive plan such as rearrangement of the station.

The normal basis has the advantage that the result of squaring an element is simply the right cyclic shift of its coordinates in hardware implementation over finite fields. In particular, the optimal normal basis is the most efficient to hardware implementation over finite fields. In this paper, we propose an efficient parallel architecture which transforms the Gaussian normal basis multiplication in GF($2^m$) into the type-I optimal normal basis multiplication in GF($2^{mk}$), which is based on the palindromic representation of polynomials.

Sensor networks consist of sensor nodes with small-size, low-cost, low-power, and multi-functions to sense, to process and to communicate. Minimizing power consumption of sensors is an important issue in sensor networks due to limited power in sensor networks. Clustering is an efficient way to reduce data flow in sensor networks and to maintain less routing information. In this paper, we propose a multi-hop clustering mechanism using global and local ID to reduce transmission power consumption and an efficient routing method for improved data fusion and transmission.

This paper proposes the demand-side management(DSM) monitoring system of high efficient end-use appliances considering demand-side bidding (DSB). The effect on the market propagation of high efficient appliances by demand side bidding is analysed. Seasonal Peak demand forecasting and propagation capacity of these appliances are analysed.

This paper has been proposed about the efficient ACL data transmission method by link quality for Bluetooth. By tile host tile HCI command confirm tile link quality values and change the packet type into several environment. And then we can analyze the data rate through this. From the construed result, after the suitable ACL packet type had been selected, the efficient data transmission method was proposed.

This paper presents tile efficient polling architecture for simple network management protocol (SNMP). Now a day, tile internet traffics have been increasing rapidly within a few years as the subscriber's network to connect internet is provided commonly. With this trend, the network management traffics also make the same phases. To provide numerous higher Quality services to the customers, the management traffic must be controlled within the permitted limit. This paper proposes the policy-based felling architecture for SNMP MIB with several parameters and suggests the data collecting layer architecture for the efficient polling.

An efficient method for thermal modeling of QFP is Proposed. Thermal measurement data are given to verify the method. In parallel with the experiment, an exact full 3-D model calculation is also provided. One fonds that there is an excellent agreement between validation data and the efficient model data.

Fuzzy approaches used to solve MONLP(Multiobjective Nonlinear Programming Problem) are based on the max-min method of fuzzy sets theory However, since the min operator noncompensatory, these approaches can not guarentee an efficient solution to the problem. In this paper, we presents an algorithm for finding the aggregation operator to find efficient solution. In particular, our presented algorithm is guarentee an efficient solution. On the basis of proposed algorithm, an illustrative numerical example is presented.

Exact $D_{s}$-efficient designs for the precise estimation of all the coefficients of the quadratic terms are studied in a quadratic response surface model. Efficient exact designs are constructed for 2 q 5 w.r.t. $D_{s}$-optimaity criterion based on Pesotchinsky's(1975) and approximate $D_{s}$-optimal design given in Lim & Studden(1988) . Moreover, they seem to have reasonably good D-efficiencies. Similar idea could apply to q$\geq$6 cases.
