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

Complete Study of Hadroproduction of a Meson Associated with a Prompt
We present the first complete study of and prompt
production from single-parton scattering, including the complete
color-singlet contribution, the
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 and 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 mb at
confidence level from the D0 measurement.Comment: 11 pages, 4 figures, 4 tables; v2: journal version, update the
