ROLE OF α-PSEUDO-UNIVEX FUNCTIONS IN VECTOR VARIATIONAL-LIKE INEQUALITY PROBLEMS

In this paper, we introduce a new class of generalized convex function, namely, a-pseudounivex function, by combining the concepts of pseudo-univex and α-invex functions. Further, we establish some relationships between vector variational-like inequality problems and vector optimization problems under the assumptions of α-pseudo-univex functions. Results obtained in this paper present a refinement and improvement of previously known results.     

A Brief Discussion on Streaming Teaching for Non-English Majors in Vocational & Technological Colleges

Streaming teaching is adopted gradually for non-English majors in some vocational & technological colleges,and in this thesis the advantages and problems of the method are discussed according to the teaching practice.Furthermore,as a consideration of the streaming teaching,much more progress is expected to be made in the future English teaching with the help of the thesis.

冬虫夏草菌丝体对小鼠体液免疫的影响

本文采用血清溶血素测定新方法,对兰州三爱堂解放军第一医院人工发酵培养的冬虫夏草菌丝体进行实验分析。结果表明,对正常小鼠的体液免疫功能无影响,但对由环磷酰胺引起的体液免疫功能低下有明显的恢复,说明该菌丝体与天然虫草有一致的功能。     

Channel Mismatching in Sidelobe Canceler: Limitations and Remedies

After a brief recall of the Sidelobe Canceler (SLC) working principle, including the derivation of a general formula for the Cancellation Ratio (CR), the effects of channel mismatching are investigated. In particular, curves providing CRvalues as a function of amplitude and phase channel mismatching, radar bandwidth, and jammer direction of arrival (JDOA) are provided for the cases of one and two auxiliary antennas. Subsequently, a time -space processor for performance restoration is analyzed in detail. In addition to the above mentioned quantities, the attainable CR value is expressed as a function of the space-time processor parameters. The contribution of the paper is related to the derivation of a number of mathematical equations of CR for several cases of practical interest for the radar engineer. In addition, several curves are presented to assist design of SLC systems.
