In hierarchical multi-tier network, preventing unnecessary handover is one of the most important matters to prevent performance degradation. To do this, some recent handover approaches propose to delay the handover from macro to small scale cell. So, in this paper, we introduces a concept of delaying inter-tier handover techniques to prevent temporary visitor being handed over to small cell.

This study sought to examine the effects of Tier 2 intervention in a multitiered model on the performance of firstand secondgrade students who were identified as having mathematics difficulties. A regression discontinuity design was utilized. Participants included 126 (Tier 2, n = 26) first graders and 140 (Tier 2, n = 25) second graders. Tier 2 students received 15min intervention booster less...

Popular Internet applications deploy a multi-tier architecture, with each tier provisioning a certain functionality to its preceding tier. In this paper, we address the challenging session-based admission control issue for multi-tier Internet applications. The session-based admission control approach (SBAC) designed for a single Web server is not effective for a multi-tier architecture. This is...

Modern Internet services employ a multi-tier architecture. While facilitating flexible service deployment, the tiered architectures introduce several significant challenges. Complex inter-tier dependencies and dynamic bottleneck tier shift are challenges inherent to multi-tier architectures. Highly dynamics of session-oriented Internet workloads further magnifies the complexity of multi-tier In...

Many natural superhydrophobic structures have hierarchical two-tier roughness which is empirically known to promote robust superhydrophobicity. We report the wetting and dewetting properties of two-tier roughness as a function of the wettability of the working fluid, where the surface tension of water/ethanol drops is tuned by the mixing ratio, and compare the results to one-tier roughness. Whe...

In these days, Security is necessary for all the applications on the network. Number of mechanisms is used for the purpose of providing the security to many applications. But for the N-Tier architecture there is no such type of mechanism is implemented for security till now. N-tier architecture has number of levels or tier, and for each tier security is essential. For providing the security to ...

This article is inspired by a recent posting on the AISWorld listserv eliciting thoughts on the practice of self-citations by journals in the IS field. While emotions ran high in the ensuing online discussion, we try to provide an objective and informed analysis of the actual citation patterns of both top tier journals and non-top tier journals. Results show that the practice of selfcitation is...

This article summarizes our approach to the management of children and adults with primary immune thrombocytopenia (ITP) who do not respond to, cannot tolerate, or are unwilling to undergo splenectomy. We begin with a critical reassessment of the diagnosis and a deliberate attempt to exclude nonautoimmune causes of thrombocytopenia and secondary ITP. For patients in whom the diagnosis is affirm...

This paper proposes a preliminary prosodic annotation system for Taiwan Hakka, “Taiwan Hakka Tones and Break Indices” is called TWHK_ToBI. TWHK_ToBI includes five tiers: ortho, words, tones, breaks, and miscellaneous. The ortho tier contains Romanization of each syllable and dictionary-defined tones; the words tier includes alphabetized SAMPA spellings of each word; the tones tier includes the ...
