Evaluation of context awareness algorithms for recommending mobile content by Dong, Hong Liang

“…The experiment results indicated that the location-based generalized pre-filtering algorithm has higher accuracy than weight post-filtering algorithm; and for generalized pre-filtering, accuracy of usage increases when the range of generalized location increases reasonably. …”

Functional characterization of plasmodium falciparum reticulocyte binding like protein homologue 1 (PfRH1) by Yap, Sally Shu Lin

“…Merozoite surface exposure of PfNBR occurs when merozoites are in close contact to erythrocytes, suggesting that PfRH1 could act as an ATP sensor to detect near-membrane environmental ATP released from a deforming erythrocyte during invasion. …”

Development of localization algorithms for a WiFi based indoor positioning system with machine learning techniques by Lu, Xiaoxuan

“…Experimental results show that the DZ-ELM based IPS can not only provide higher accuracy, but also improve the repeatability of IPSs. Secondly, when assuming that noises lie in both input and output data, we exploit the fact that feature mapping in ELM is known to users to develop two kinds of robust ELM (RELM) based on second order cone programming. …”

Three essays on corporate finance by Fu, Kangkang

“…These results are more pronounced when customers’ environmental risk is lower. Collectively, our findings suggest that improving the trading relationship with principal customers is an important channel through which firms can benefit economically from being environmentally responsible. …”

Transition metal doped apatites as inert non-toxic pigments by Seah, Jasmine Si Han

“…This form of crystal structure is retained when apatite was doped with copper. The synthesized samples underwent phase characterisation using X-ray diffraction followed by Rietveld refinements of the data collected with the aid of the TOPAS4-1 software. …”

Customer co-creation in B2C e-commerce: does it lead to better new products? by Pee, Loo Geok

“…Based on the co-creation and innovation literature, it is hypothesized that idea co-creation has a stronger impact when there is also decision co-creation. Further, co-creation in the product design stage is expected to have a stronger effect on product innovativeness, while co-creation in the commercialization stage has a stronger effect on product sales. …”

Towards compressed sensing for ground-to-air monostatic radar by Dauwels, Justin, Kannan, Srinivasan

“…We provide numerical results for both scenarios, and demonstrate that a proportional reduction in reconstruction error is obtained if coherent integration is carried out before CS reconstruction, corresponding to an effective gain of SNRg = 10 log10 N. On the other hand, when coherent integration is performed after applying CS reconstruction to single pulse radar returns, there is negligible gain. …”

Novel Pd2Se3 Two-Dimensional Phase Driven by Interlayer Fusion in Layered PdSe2 by Lin, Junhao, Zuluaga, Sebastian, Yu, Peng, Liu, Zheng, Pantelides, Sokrates T., Suenaga, Kazu

“…Two-dimensional (2D) materials are easily fabricated when their bulk form has a layered structure. The monolayer form in layered transition-metal dichalcogenides is typically the same as a single layer of the bulk material. …”

Two kinds of phase transition in photonic systems with application to optical isolation by Zhou, Xin

“…The behavior of the Dirac modes can be described by a gyromagnetic effective medium model with near-zero refractive index. When two domains are subjected to opposite magnetic biases, there exist unidirectional edge states along the domain wall. …”

Stack sizing for optimal current drivability in subthreshold circuits by Kim, Tony Tae-Hyoung, Keane, John., Eom, Hanyong., Sapatnekar, Sachin., Kim, Chris H.

“…Subthreshold circuit designs have been demonstrated to be a successful alternative when ultra-low power consumption is paramount. However, the characteristics of MOS transistors in the subthreshold region are significantly different from those in strong inversion. …”

Bondi mass with a cosmological constant by Saw, Vee-Liem

“…Furthermore, with MΛ=MB, we show that for purely quadrupole gravitational waves given off by the isolated system (i.e., when the “Bondi news” σo comprises only the l=2 components of the spherical harmonics with spin-weight 2) the energy carried away is manifestly positive definite for the Λ>0 case. …”
