学位级别：硕士

the terms relational and social victimization are particularly similar with respect of the types of manipulative acts involved. they differ slightly in their emphasis in researcher’s conceptualization. Manipulative acts of relational and social victimization normally disrupts relationships, group acceptance and damaging others social standing through overt and covert forms. the current retrospective study investigated the perceptions of relational and social aggression and coping skills among 200 Africans and Western （Americans, Canadians, Australians and Europeans） students in Chinese Universities. the Social Experience Questionnaire on Relational and Social Victimization （SEQRSV） was used to assess perceived relational and social victimization effects whilst the Self-Report Coping Questionnaire assesses coping strategies from perceived relational and social victimization.

Design and Analysis of an Adaptive handover Protocol for 4G Networks

the future generation networks or 4G networks constitute of varied technologies converged over the Internet protocol version 6(IPv6) core. the 4G networks offer varied services over different interfaces to the user nodes. Mobility management in 4G networks is an issue that exists. the handover protocols for mobility management in 4G networks that currently exist, do not consider wireless signal degradation during handover operations. this paper introduces the Noise Resilient Reduced Registration time Care of Mobile IP(NR RRtC:MIP) protocol for handover management. A handover decision algorithm based on the signal strength measured by the user nodes is considered in the NR RRtC: MIP protocol. A simulation study is discussed in the paper to evaluate the performance of the NR RRtC: MIP protocol. the results obtained from the simulation study prove that the NR RRtC: MIP protocol effectively reduces handover latencies and improves network performance.

this paper offers a systematic literature review of real-time detection and classification of Power Quality Disturbances(PQDs).A particular focus is given to voltage sags and notches,as voltage sags cause huge economic losses while research on voltage notches is still very incipient.A systematic method based on scientometrics,text similarity and the analytic hierarchy process is proposed to structure the review and select the most relevant literature.A biblio-metric analysis is then performed on the bibliographic data of the literature to identify relevant statistics such as the evolution of publications over time,top publishing countries,and the distribution by relevant topics.A set of articles is subsequently selected to be critically *** critical review is structured in steps for real-time detection and classification of PQDs,namely,input data preparation,preprocessing,transformation,feature extraction,feature selec-tion,detection,classification,and *** associated with the type of disturbance(s)addressed in the literature are also explored throughout the review,including the perspectives of those studies aimed at multiple PQDs,or specifically focused on voltage sags or voltage *** real-time performance of the reviewed tools is also ***,unsolved issues are discussed,and prospects are highlighted.
