3D Face Recognition Based on Decision Fusion
Authors: Zhong Rongqing , Li Jing
Published: March 2012

In this paper, we propose the algorithm of 3D face recognition based on decision fusion. In the algorithm, firstly, it uses PCA or LPP to extract the features of 2D normalized grey image and compute Euclidean distance between the testing sample and the training sample as one matching score. We process the 3D depth image with multilevel B-splines approximation and ICP method correction. Then we can obtain another matching score by using PCA or LPP to extract the features of 3D depth image. Finally, decision fusion results can be gained by fusing the two scores. The experimental results indicate that the recognition rate of the decision fusion method which uses LPP to extract the 3D image features is higher than any single algorithm, and the recognition performance is improved greatly.

Adaptive Call Admission Control for Mobile Networks
Authors: Rajeswari S. , Chandrasekaran S.
Published: March 2012

Call admission protocols play a central role in determining both the performance of any network, and the revenue of the network. The call admission protocol must decide either to accept the call or reject it. An adaptive call admission control algorithm is proposed here. In non adaptive algorithms the call is allocated its maximum bandwidth and this bandwidth cannot be altered throughout the call's lifetime. But in the model proposed here the bandwidth is adaptive in nature and the bandwidth can be upgraded or degraded depending on the call type.

Published: March 2012

When Running Linux on a multi-core processor, all of the network processing is processed by the operating system and the processing efficiency is very poor. To solve this problem, we describe a Multi-core Network Processing System (MNPS) in this paper. The MNPS divides the cores of a multi-core processor into two groups. One group runs MNPS-Linux, which is a modified Linux only retaining the same socket interface to the user applications. The other group runs MNPS-Stack, which processes the network stack without operating system and directly operates the hardware resources. Because of the offloading of network processing and no interrupt in MNPS-Linux and the directly operating the hardware resources and no operating system in MNPS-Stack, MNPS is very efficient. We can see from the result of the experiment that MNPS can get high performance but consumes less CPU resource.

In particular, ZnO nanostructures were synthesised from Ar-O2 plasmas using a Zn(II) bis(ketoiminate) precursor at 300 °C and 1.0 mbar, with an RF-power of 20 W. Subsequently, Ag was sputtered on the obtained systems under mild conditions (Ar, total pressure = 0.3 mbar; substrate temperature = 60 °C; RF-power = 5 W). The structural, morphological and compositional features of the obtained nanosystems were analysed by Glancing Incidence X-ray Diffraction (GIXRD), Field Emission-Scanning Electron Microscopy (FE-SEM) and Energy Dispersive X-ray Spectroscopy (EDXS). To attain a detailed insight into the chemical characteristics of the Ag/ZnO nanocomposites, this contribution is devoted to the investigation of a representative specimen by X-ray Photoelectron (XPS) and X-ray Excited Auger Electron (XE-AES) Spectroscopies. In particular, the attention is focused on the analysis of the O 1s, Zn 2p3/2, Zn 3p and Ag 3d core levels, as well as zinc and silver Auger signals. The results highlight an appreciable silver surface oxidation and an electronic interplay between Ag/Ag2O and ZnO phases.

Purpose:

The purpose of this work is threefold: (1) to explore biological consequences of the multileaf collimator (MLC) calibration errors in intensity modulated radiotherapy (IMRT) of prostate and head and neck cancers, (2) to determine levels of planning target volume (PTV) and normal tissue under‐ or overdose flagged with clinically used QA action limits, and (3) to provide biologically based input for MLC QA and IMRT QA action limits.

Methods:

Ten consecutive prostate IMRT cases and ten consecutive head and neck IMRT cases were used. Systematic MLC offsets (i.e., calibration error) were introduced for each control point of the plan separately for X1 and X2 leaf banks. Offsets were from − 2 to 2 mm with a 0.5 mm increment. The modified files were imported into the planning system for forward dose recalculation. The original plan served as the reference. The generalized equivalent uniform dose (gEUD) was used as the biological index for the targets, rectum, parotid glands, brainstem, and spinal cord. Each plan was recalculated on a CT scan of a 27 cm diameter cylindrical phantom with a contoured 0.6 cc ion chamber. Dose to ion chamber and 3D gamma analysis were compared to the reference plan. QA pass criteria: (1) at least 95% of voxels with a dose cutoff of 50% of maximum dose have to pass at 3 mm/3% and (2) dose to chamber within 2% of the reference dose.

Results:

For prostate cases, differences in PTV and rectum gEUD greater than 2% were identified. However, a larger proportion of plans leading to greater than 2% difference in prostate PTV gEUD passed the ion chamber QA but not 3D gamma QA. A similar trend was found for the rectum gEUD. For head and neck IMRT, the QA pass criteria flagged plans leading to greater than 4% differences in PTV gEUD and greater than 5% differences in the maximum dose to brainstem. If pass criteria were relaxed to 90% for gamma and 3% for ion chamber QA, plans leading to a 5% difference in PTV gEUD and a 5%–8% difference in brainstem maximum dose would likely pass IMRT QA. A larger proportion of head and neck plans with greater than 2% PTV gEUD difference passed 3D gamma QA compared to ion chamber QA.

Conclusions:

For low modulation plans, there is a better chance to catch MLC calibration errors with 3D gamma QA rather than ion chamber QA. Conversely, for high modulation plans, there is a better chance to catch MLC calibration errors with ion chamber QA rather than with 3D gamma QA. Ion chamber and 3D gamma analysis IMRT QA can detect greater than 2% change in gEUD for PTVs and critical structures for low modulation treatment plans. For high modulation treatment plans, ion chamber and 3D gamma analysis can detect greater than 2% change in gEUD for PTVs and a 5% change in critical structure gEUD since either QA methods passes the QA criteria. For gEUD changes less than those listed above, either QA method has the same proportion of passing rate.

Objectives

To assess functional changes measured by cerebral blood flow (CBF) in the presymptomatic stage of frontotemporal dementia linked to chromosome 3 (FTD-3) caused by a truncating mutation inCHMP2B.

Design

Case–control study.

Setting

A memory clinic and tertiary referrals centre for dementia and inherited neurodegenerative disorders.

Participants

The authors included 11 presymptomaticCHMP2Bmutation carriers and seven first-degree-related family non-carriers. Participants were MRI scanned twice with an interval of 15 months.

Primary and secondary outcome measures

Local functional changes in brain tissue perfusion were measured as CBF with two different MR techniques, gradient echo (GRE) and spin echo (SE), focusing on CBF in all cerebral vessels (GRE) and cerebral capillaries (SE), respectively. As planned, data analysis included co-registration of perfusion images to structural T1 images. Perfusion data were then extracted from seven regions-of-interest, normalised to white matter and statistically compared between carriers and non-carriers.

Results

For SE, contrasts between carriers and non-carriers showed significant differences in temporal, occipital and parietal lobes and in hippocampus. There was no evidence of changes from baseline to follow-up. For GRE, there were no significant differences between carriers and non-carriers.

Conclusions

Significantly decreased CBF was found in presymptomaticCHMP2Bmutation carriers in occipital-and parietal lobes. Comparing SE with GRE, data indicate that FTD-3 vascular pathology might primarily affect brain capillaries.
A serial qualitative interview study of infant feeding experiences: idealism meets realism
Authors: Hoddinott Pat , Craig Leone C A , Britten Jane , McInnes Rhona M
Published: March 2012

Objective

To investigate the infant feeding experiences of women and their significant others from pregnancy until 6 months after birth to establish what would make a difference.

Design

Qualitative serial interview study.

Setting

Two health boards in Scotland.

Participants

72 of 541 invited pregnant women volunteered. 220 interviews approximately every 4 weeks with 36 women, 26 partners, eight maternal mothers, one sister and two health professionals took place.

Results

The overarching theme was a clash between overt or covert infant feeding idealism and the reality experienced. This is manifest as pivotal points where families perceive that the only solution that will restore family well-being is to stop breast feeding or introduce solids. Immediate family well-being is the overriding goal rather than theoretical longer term health benefits. Feeding education is perceived as unrealistic, overly technical and rules based which can undermine women's confidence. Unanimously families would prefer the balance to shift away from antenatal theory towards more help immediately after birth and at 3–4 months when solids are being considered. Family-orientated interactive discussions are valued above breastfeeding-centred checklist style encounters.

Conclusions

Adopting idealistic global policy goals like exclusive breast feeding until 6 months as individual goals for women is unhelpful. More achievable incremental goals are recommended. Using a proactive family-centred narrative approach to feeding care might enable pivotal points to be anticipated and resolved. More attention to the diverse values, meanings and emotions around infant feeding within families could help to reconcile health ideals with reality.
Study protocol: a cross-sectional survey of seasonal affective disorder in Danish populations with and without severe visual impairments: Table 1
Authors: Madsen Helle Østergaard , Dam Henrik , Hageman Ida
Published: March 2012

Introduction

People with seasonal affective disorder (SAD) experience recurrent seasonal fluctuations in energy, mood and appetite. Retinal light exposure is suggested to play an important role in the pathogenesis and treatment of SAD. The aim of the study is to determine the prevalence of SAD in persons with severe visual impairments or blindness and to compare the results to a control group without visual impairments. Moreover, the authors wish to investigate whether SAD is correlated to the degree of impairment or to the diagnosis.

Methods and analysis

2781 persons with visual impairments ranging from total blindness to Snellen visual acuity 6/60 receive information letter and questionnaire by post. Completed questionnaires can be returned by post, email or telephone. For each respondent, all eye-related diagnoses will be obtained from national registries. Normally sighted and demographically matched control respondents will be contacted in a similar manner the subsequent winter season. The Seasonal Pattern Assessment Questionnaire rates seasonal variation within the six items: sleep, appetite, social activity, mood, energy and body weight. The Seasonal Pattern Assessment Questionnaire yields a Global Seasonal Score and a prevalence of SAD. Outcomes from the two groups will be compared. Moreover, outcomes from subgroups of the visually impaired population will be compared.

Ethics and dissemination

The study is approved by the Danish Data Protection Agency. Results will be published in a relevant scientific journal and be communicated to respondents and relevant institutions through cooperation with the Danish Association of the Blind.
