Method of Homomorphic Encryption

The existing homomorphie eneryption scheme is based on ring of the integer, and the possible operators are restricted to addition and multiplication only. In this paper, a new operation is defined Similar Modul. Base on the Similar Modul, the number sets of the homomorphic encryption scheme is extended to real number, and the possible operators are extended to addition, subtraction, multiplication and division. Our new approach provides a practical ways of implementation because of the extension of the operators and the number sets.

海口市番茄反季节栽培品种比较试验初报

海口市番茄生产的正常季节是冬种春收。其产量虽然较高,但产值较低。本试验是通过引进耐热番茄品种,将播种期推迟到二月春种夏收,即反季节栽培。试种结果初步表明:泰引3号、扬帆2号等引进品种,在气温较高的条件下,植株生长正常,座果率较高,产量与品质能达到当地正常季节栽培的水平。我们初步认为,泰引3号比较理想,可在海口市郊进一步试种。

Intelligent Control Mechanism of Part Picking Operations of Automated Warehouse

This paper studies the part picking operations of a ut omated warehouse. It assumed the demand of picking orders of automated warehouse are dynamic generated. Once the picking orders of certain period of time are kn own, it is necessary to decide an efficient order picking sequence and routing t o minimize the total travel distance to complete those orders. Assumed there are n i items to be picked in order O i. Each item in the picking ord er is located in different locations in the warehouse. Since i...     

Mechanism of Microwave Effects on Conductivity of Solution

The relation between microwave conductivity and normal conductivity of solution is compared in this thesis. By building mathematical model and theoretical analyses, it indicates that the relationship of in situ conductivity of solution in microwave field and temperature is similar to that in non-microwave field. It can be expressed by quadratic equation but the values of both conductivities are different. Microwave field has effect on the mean path δ or hot vibrational frequency v of ions in solution. In microwave field, the mean energy barrier, which ions must surmount as they transit, is the function relation to temperature.
