Home buyers' purchase decision framework for Klang Valley, Malaysia

To solve the property overhang issues in Malaysian housing market, housing developers require answers and solutions for housing attributes and services to increase their sales. However, previous researchers only focused on one aspect while studying house buyers' purchase-decision. So, to overcome the problems of property overhang and low satisfaction-level, this research aims to investigate the housingpurchase factors, homebuyers' demographic, purchase decision and satisfaction. The chosen research method is Quantitative method as there is a large sample of population. Finally, it has developed a Home Buyers' Purchase Decision Framework for the home buyers in Klang Valley. The researcher has collected data using SurveyMonkey, an online survey tool and has developed a questionnaire specifically to Klang Valley residents for their opinions on housing purchase factors, purchase decision and post-purchase satisfaction. A total of 417 questionnaires were returned from the 2,000 distributed. Then, the data was analyzed using logistic regression, multivariate analysis of variance and multiple linear regression. This result is then validated by 24 respondents to increase the accuracy. The findings show that home buyers’ purchase decision are influenced by all house purchase factors: house structure, spaces, finance, location, and neighbourhood. However, gender, marital status, and family income of home buyer do not influence house purchase decision and financial factors do not have significant influence on home buyers' satisfaction. The results will make contributions to the Malaysian residential housing industry, give the housing developers a wider comprehension of their consumers and lay a foundation for the housing industry to improve. For the recent years, this research is the only known study that develops homebuyers' purchase-decision framework for Klang Valley housing market. Thus, this study contributes to the knowledge of homebuyers decision-making processes for the housing market in Malaysia

EMM: Energy-Aware Mobility Management for Mobile Edge Computing in Ultra Dense Networks

Merging mobile edge computing (MEC) functionality with the dense deployment of base stations (BSs) provides enormous benefits such as a real proximity, low latency access to computing resources. However, the envisioned integration creates many new challenges, among which mobility management (MM) is a critical one. Simply applying existing radio access oriented MM schemes leads to poor performance mainly due to the co-provisioning of radio access and computing services of the MEC-enabled BSs. In this paper, we develop a novel user-centric energy-aware mobility management (EMM) scheme, in order to optimize the delay due to both radio access and computation, under the long-term energy consumption constraint of the user. Based on Lyapunov optimization and multi-armed bandit theories, EMM works in an online fashion without future system state information, and effectively handles the imperfect system state information. Theoretical analysis explicitly takes radio handover and computation migration cost into consideration and proves a bounded deviation on both the delay performance and energy consumption compared to the oracle solution with exact and complete future system information. The proposed algorithm also effectively handles the scenario in which candidate BSs randomly switch on/off during the offloading process of a task. Simulations show that the proposed algorithms can achieve close-to-optimal delay performance while satisfying the user energy consumption constraint.Comment: 14 pages, 6 figures, an extended version of the paper submitted to IEEE JSA

Complete Study of Hadroproduction of a Υ\Upsilon Meson Associated with a Prompt J/ψJ/\psi

We present the first complete study of $\Upsilon$ and prompt $J/\psi$ production from single-parton scattering, including the complete $\mathcal{O}(\alpha_S^6)$ color-singlet contribution, the $\mathcal{O}(\alpha_S^2\alpha^2)$ electroweak contribution, the complete nonrelativistic S-wave and P-wave color-octet contribution as well as the feeddown contribution. Our study was motivated by the recent evidence reported by D0 Collaboration of prompt $J/\psi$ and $\Upsilon$ simultaneous production at the Tevatron. With our complete evaluation, we are able to refine the determination of the double parton scattering contribution made by D0 Collaboration. We find that the effective cross section characterizing the importance of double-parton scatterings is $\sigma_{\rm eff}\le 8.2$ mb at $68\%$ confidence level from the D0 measurement.Comment: 11 pages, 4 figures, 4 tables; v2: journal version, update the references and fix a few typo
