A SMARTPHONE-BASED 3D PIPELINE FOR THE CREATIVE INDUSTRY– THE REPLICATE EU PROJECT

Abstract. During the last two decades we have witnessed great improvements in ICT hardware and software technologies. Three-dimensional content is starting to become commonplace now in many applications. Although for many years 3D technologies have been used in the generation of assets by researchers and experts, nowadays these tools are starting to become commercially available to every citizen. This is especially the case for smartphones, that are powerful enough and sufficiently widespread to perform a huge variety of activities (e.g. paying, calling, communication, photography, navigation, localization, etc.), including just very recently the possibility of running 3D reconstruction pipelines. The REPLICATE project is tackling this particular issue, and it has an ambitious vision to enable ubiquitous 3D creativity via the development of tools for mobile 3D-assets generation on smartphones/tablets. This article presents the REPLICATE project’s concept and some of the ongoing activities, with particular attention being paid to advances made in the first year of work. Thus the article focuses on the system architecture definition, selection of optimal frames for 3D cloud reconstruction, automated generation of sparse and dense point clouds, mesh modelling techniques and post-processing actions. Experiments so far were concentrated on indoor objects and some simple heritage artefacts, however, in the long term we will be targeting a larger variety of scenarios and communities.
Evaluation of SEREX defined antigens by mRNA expression analysis in breast cancer tissues of Egyptian patients

The identification of human cancer antigens has opened new approaches to the development of cancer vaccines. Characterization of the defined antigens including mRNA expression analysis, protein analysis, antibody response and epitope identification are important to assess the value of those antigens.The aim of the present work is to identify tumor specific or tumor associated antigens by serological analysis of recombinant cDNA expression library (SEREX). Different cancer cell lines and normal testis were used as a source of cDNA library in this study including lung cancer, renal cancer, colon cancer and ovarian cancer in addition to a testicular library. For immunoscreening, autologous as well as allogeneic sera were obtained. By autologous immunoscreening, we previously reported the SEREX analysis of the lung adenocarcinoma cell line OU-LU-6 including the identification of the cancer/testis antigen XAGE-1b. We also reported the SEREX analysis of the lung adenocarcinoma cell lines OU-LU-17 and OU-LU-11. This work focused on the defined SEREX genes by autologous and allogeneic immunoscreening of the renal cancer cell line RC-1. The total number of defined clones was 51 representing 39 different genes named OYREN-1 through OY-REN-39. The vast majority of clones identified by SEREX are ubiquitously expressed genes. In the renal cancer cell line RC-1, OY-REN-1, 3, 18, 29 and 31 genes were the most frequently isolated (3 of 51), subsequently, OY-REN-2 and 30 were the second most frequent isolated genes, each was represented by 2 of 51 clones. All other genes were represented by a single clone. Within the isolated genes, protein kinase c, Iota (PKCI) which clones had a deletion compared to sequences in the database which might give the chance to identify a new isoform. mRNA expression analysis of PKCI in normal as well as breast cancer tissues showed no cancer specific characteristics compared to the cancer/testis antigen XAGE-1b and c variants. Very interestingly, XAGE-1b antigen showed a significantly high frequency of expression in breast cancer tissues (5/10) taken from Egyptian patients. Using the SEREX defined antigens for mRNA expression in breast cancer tissues may aid the development of diagnostic and immunotherapeutic agents for patients with breast cancer in Egypt.
Mechanical Characterization of Biomolecules in Liquid using Silicon Tweezers with Subnanonewton Resolution

Molecular biophysicists seek to understand how biological systems work through mechanical or electrical characterizations performed at the molecular scale. From this perspective, we have devised a silicon-based micromechanical tool for stress-strain measurements of molecular fibers and demonstrated micromanipulation and biomechanical characterization of DNA bundles in a liquid solution. By combining this instrument with a microscopic displacement measurement technique based on Fourier transform image processing, we could achieve a force resolution of 25 pN - a level which is within the single-molecule sensing range - and validate a novel approach for stress-strain measurements.
A Remark on Stabilization of Chua's Circuit

Chua's circuit has been a test-bed for studying various control problems such as chaos cancellation, synchronization, or stabilization. The circuit has been viewed as a lower triangular system and controlled as such by various state feedback control methods. In this note, we first point out that Chua's circuit can be viewed as a nonlinear system in output feedback form. Therefore, it can be controlled by output feedback control law using some well established control techniques for output feedback systems. As an illustration, we have designed a simple adaptive robust output feedback control law to globally stabilize the circuit with arbitrary variations of the parameters of the circuit.
Development of Precision Underwater Positioning System

The Shimonoseki Research and Engineering Office for Port and Airport, Kyushu Regional Development Bureau, Ministry of Land, Infrastructure and Transport in cooperation with the Oki Electric Co. Ltd, has developed the advanced underwater positioning system. A measurement of position x, y and z of underwater structure is needed to settle the structure in water, and to manage the construction in port area. A quality inspection of structures at port such as pier by the Remote of Vehicle (ROV) is also needed to grasp its exact 3 dimensional position in water for manipulating it. Presently, the above mentioned underwater measurement work, particularly required high accuracy, is needed many workers, surveyors work on land for measuring the scale of underwater-staff and divers work in water for supporting the underwater-staff, and is met highly risks of incident. Especially, in case of the offshore working, longer distance from land and deeper depth of water are cause of difficulty of its implementation. To cope with these issues, we have developed the system and have verified its effectiveness by demonstration on the sea. The system consists of 2 measurement technologies, the Global Positioning System (GPS) is utilized measuring on water and supersonic wave with ROV is for probing under water. Using the system can be readily available to high accuracy measurement without divers, even offshore working. This paper presents outline of the system and the result of the demonstration.
Distributed fault diagnosis of wireless sensor networks

In wireless sensor networks (WSN), faults occurring to sensor nodes are common due to the sensor device itself and the harsh deployment environment. In order to avoid degradation of service due to faults, it is necessary for the WSN to be able to detect faults early. In this paper we propose a localized fault diagnosis algorithm which executes in tree-like networks effectively. It is based on local comparisons of sensed data and dissemination of the test results to the remaining sensors. Furthermore, Times redundancy is used to diagnose the intermittent fault in sensing and communication. Simulation results show the proposed algorithm has high detection accuracy and low false alarm rate.
Secure Health Information in Mobile Applications

Implementing a mobile application secure enough to store personal medical information and properly enforce security policies is an important task. There is currently no good implementation of document level security for patient information, and there is no way to properly enforce HIPAA medical privacy law. To try to resolve this, we have created a granular, role-based access control model for XML schemas and applied this model to digital medical records. Using JAVA Eclipse IDE, the Android SDK and JavaScript Object Notation (JSON) we adapted a mobile application called the Personal Health Assistant (PHA). This application interacts with Microsofts HealthVault through JSON API calls. We split the application into two separate implementations, and modified each with different objectives. One application is designed for the medical provider, and the other for the patient. In the future, both applications can be transitioned to use XML and Open mHealth standards.
High resolution low power 0.6µm CMOS 40MHz dynamic latch comparator

In order to diminish circuit complexity and power dissipation, the simple configuration of the dynamic latch comparator is revisited. This paper proposes and analyzes a comparator that consists of a preamplifier using negative resistance as a load and a double regenerative dynamic latch. A discussion of the dynamic latch is presented and the effect of transistor sizes in the time constant and the offset voltage is explained briefly. The comparator is designed in a 0. 6µm CMOS technology. Monte Carlo simulation using Virtuoso® Spectre shows that the comparator has a resolution of 1.8mV and dissipates 750µW of power when working at 40MHz.
EFFECT OF RAW CAMEL MILK IN TYPE 1 DIABETIC PATIENTS : 1 YEAR RANDOMISED STUDY

The efficacy of camel milk consumption as an adjunct to routine diabetic management in maintaining long-term glycaemia control in type I diabetes was assessed during a 52 week randomised study. Throughout the duration of the study, 12 randomly assigned patients underwent routine diabetic management (diet, exercise and parental insulin supplementation) and 12 randomly assigned patients additionally undertook daily consumption of raw camel milk (500ml/day). In both groups, the dose of parenteral insulin administration was adjusted to maintain an euglycaemic state. Glycosylated haemoglobin (HbA1c) and body mass index (BMI) were measured at the initiation of the study and monitored at 3 monthly intervals. Additionally, plasma insulin, C-peptide and anti-insulin antibodies were measured at the beginning and end of the study. In the group receiving camel milk, there was a significant increase in MBI (17 ± 4.4 to 19.7 ± 2.97; p < 0.001) and a significant reduction in HbA1c (7.8 ± 1.38 to 6 ± 0.96; p < 0.001), mean blood glucose (119 ± 19 to 95.42 ± 15.70; p < 0.001) and necessary insulin dose (32 ± 12 to 17.88 ± 12.40; p < 0.005) compared to the values at the initiation of the study. There was no significant change in c-peptide (0.18 ± 0.04 to 0.24 ± 0.07) or antiinsulin antibodies (22.92 ± 5.45 to 21.84 ± 7.34). We have demonstrated that the consumption of camel milk in type I diabetes results in a significant reduction in the dose of insulin required to maintain long-term glycaemic control. Based on our results, camel milk consumption, may therefore, be considered as a useful adjunct to parenteral insulin administration in the management of type 1 diabetes.
Parallel evolutionary computation to solve combinatorial optimization problem

Grid computing and Peer-to-Peer (P2P) computing have become a real alternatives to traditional supercomputing for the development of applications that harness massive computational resources especially applications aiming to solve the NP-Complete problem such as metaheuristics. One the promising methods is parallel programming. This concept is a powerful and necessary way to reduce the computation time of metaheuristics and/or improve the quality of the provided solutions. Different models have been proposed to exploit the parallelism of metaheuristics. These models have been and are still being largely experimented on a wide range of metaheuristics and applied to a large variety of problems in different areas. In this paper. we have proposed a hybrid parallel implementation of Ant Colony Optimization (ACO) and Genetic Algorithm (AG) by using the MPJ Express approach.
Forecasting the electrical energy price in Iran power market: A comparison between single and multi hour models

This paper discusses the electrical energy price forecasting in Iran power market. Due to the day-time variations in load and thereby electrical energy price, it is wise to use different models for forecasting energy price at different hours. In this paper, three different single-hour models are used to forecast electricity price at off peak, plateau, and peak load. A 24-hour model is also used to forecast electricity price of all hours simultaneously. Analysis of autocorrelation and partial autocorrelation functions suggests different models for each single hour model as well as the 24-hour model. The best models for off peak, plateau, and peak load are obtained to be ARIMA(1,1,1), ARIMA(2,1,1) and ARIMA(0,1,1), respectively. In addition, the time-series analyses result in an AR(2) model with 24-hour period for the 24-hour model as the most suitable model. The models are compared from viewpoints of accuracy and time consuming. The comparison shows that the user should compromise between accuracy and speed, when selecting single-hour or 24-hour models.
Experimental study of rectenna coupling at low power level

The experimental results presented in this paper focus on the performance of a rectenna array by studying the effect of mutual coupling between two rectennas. The measurements in several planes of the space are investigated and used to help us to define the minimum distance for future rectenna arrays that can be used at a low power density level. The single element chosen for the array is composed of a rectifier circuit and a CSPA (Circular Slot Patch Antenna). This study shows that at a distance greater than 6cm (λ/2) between two rectennas in reception, we observe that the DC received voltage is constant in the Y plane, while in the X plane, the DC received voltage remains constant whatever the distance. We deduce that these rectennas are uncoupled in this case. We can consider each rectenna like an independent system.
Identity-Based Random Key Predistribution for Army MANETs

Abstract : We address a challenge to developing the Future Force -- Army tactical networks require cryptographic keys to implement security services such as encryption and authentication, but current pairwise key establishment approaches using interactive public key techniques are too time-consuming. This paper describes identity-based cryptographic solutions that enable strong security and significantly reduce bandwidth consumption and latency, and provides three main contributions: (a) a description of how identity-based random key predistribution (IBRKP) can be used as a secure and efficient component within an Army tactical mobile ad hoc network (MANET) key management infrastructure; (b) a description of an attack on IBRKP resulting from targeted node compromises as opposed to random node compromises; and (c) a technique that creates grainy pool keys that increases security against targeted and random node compromise attacks.
ROBUST CONTROL DESIGN OF A SINGLE DEGREE-OF-FREEDOM MAGNETIC LEVITATION SYSTEM BY QUANTITATIVE FEEDBACK THEORY

A magnetic levitation (maglev) system is inherently nonlinear and open-loop unstable because of the nature of magnetic force. Most controllers for maglev systems are designed based on a nominal linearized model. System variations and uncertainties are not accommodated. The controllers are generally designed to satisfy gain and phase margin specifications, which may not guarantee a bound on the sensitivity. To address these issues, this paper proposes a robust control design method based on Quantitative Feedback Theory (QFT) applied to a single degree-offreedom (DOF) maglev system. The controller is designed to successfully meet the stability requirement, robustness specifications, and bounds on the sensitivity. Experiments verify that the controller maintains stable levitation even with 100% load variation. Experiments prove that it guarantees the transient response design requirements even with 100% load change and 39% model uncertainties. The QFT control design method discussed in this paper can be applied to other open-loop unstable systems as well as systems with large uncertainties and variations to improve system robustness.
Design and Implementation of Sensorless Voltage Control of Front-End Rectifier for Power Quality Improvement in Telecom System

In this paper, a three-phase three-switch three-level boost (Vienna) type pulse-width modulation rectifier is proposed as an active front-end power factor correction (PFC) rectifier for power quality improvement in telecom load. A sensorless voltage control technique is proposed and it does not rely on any input voltage information results in reliable and robust operation. A brief description on the principle of operation and the most advantageous modulation method of the proposed system are discussed. The feasible switching states are identified for the proposed active front-end converter resulting in reduced switching stress and dc ripples. A triangular carrier based control logic is applied and the input current reaches sinusoidal shape without the need of sensing the input voltage. The detailed analysis of front-end PFC converter is carried out by equivalent circuit analysis. Also, the complete loss and efficiency calculation of the converter is explicitly carried out with the help of hardware design guidelines. The performance of the proposed system and its capability of operating satisfactorily in the event of failure of one phase of the mains is verified through MATLAB Simulation, and the results obtained are presented. The experimental setup rated for 9 kW is developed in the laboratory to validate the simulation results. From the simulation and hardware results, it is observed and recorded that the power quality parameters are improved and are well within the IEEE and IEC standards.
Gain and bandwidth enhancement of stacked H-shaped patch-open ring antenna

H-shape is used to miniaturize the patch antenna. However, the gain and bandwidth of the miniaturized antenna decrease significantly. In this paper, a stacked H-shaped patch antenna with an open ring is proposed to improve the antenna gain and bandwidth. The electrical length of the proposed antenna is 0. 12λ and has a gain, impedance bandwidth and radiation efficiency of 5.7 dBi, 10.15% and 91.67%, respectively.
Winter 2010 in Europe: A cold extreme in a warming climate

The winter of 2009/2010 was characterized by record persistence of the negative phase of the North‐Atlantic Oscillation (NAO) which caused several severe cold spells over Northern and Western Europe. This somehow unusual winter with respect to the most recent ones arose concurrently with public debate on climate change, during and after the Copenhagen climate negotiations. We show however that the cold European temperature anomaly of winter 2010 was (i) not extreme relative to winters of the past six decades, and (ii) warmer than expected from its record‐breaking seasonal circulation indices such as NAO or blocking frequency. Daily flow‐analogues of winter 2010, taken in past winters, were associated with much colder temperatures. The winter 2010 thus provides a consistent picture of a regional cold event mitigated by long‐term climate warming.
Perinatal exposure to high dietary advanced glycation end products in transgenic NOD8.3 mice leads to pancreatic beta cell dysfunction

ABSTRACT The contribution of environmental factors to pancreatic islet damage in type 1 diabetes remains poorly understood. In this study, we crossed mice susceptible to type 1 diabetes, where parental male (CD8+ T cells specific for IGRP206-214; NOD8.3) and female (NOD/ShiLt) mice were randomized to a diet either low or high in AGE content and maintained on this diet throughout pregnancy and lactation. After weaning, NOD8.3+ female offspring were identified and maintained on the same parental feeding regimen for until day 28 of life. A low AGE diet, from conception to early postnatal life, decreased circulating AGE concentrations in the female offspring when compared to a high AGE diet. Insulin, proinsulin and glucagon secretion were greater in islets isolated from offspring in the low AGE diet group, which was akin to age matched non-diabetic C57BL/6 mice. Pancreatic islet expression of Ins2 gene was also higher in offspring from the low AGE diet group. Islet expression of glucagon, AGEs and the AGE receptor RAGE, were each reduced in low AGE fed offspring. Islet immune cell infiltration was also decreased in offspring exposed to a low AGE diet. Within pancreatic lymph nodes and spleen, the proportions of CD4+ and CD8+ T cells did not differ between groups. There were no significant changes in body weight, fasting glucose or glycemic hormones. This study demonstrates that reducing exposure to dietary AGEs throughout gestation, lactation and early postnatal life may benefit pancreatic islet secretion and immune infiltration in the type 1 diabetic susceptible mouse strain, NOD8.3.
Spot-size converted polarization-insensitive SOA gate with a vertical tapered submicrometer stripe structure

To develop polarization-insensitive semiconductor optical amplifier (SOA) gates into more efficient and functional optical components by using hybrid integration with a planer lightwave circuit (PLC) platform, vertical tapered spot-size converters were integrated into a SOA gate with a narrow mesa-stripe structure of submicrometer width leading to low coupling loss (2.6 dB). Very-low polarization dependence of gain (<0.2 dB) and high extinction ratio (>30 dB) were achieved in a wide wavelength range (40 nm). High-speed (<1 us) gate operation was also demonstrated. These results indicate that the spot-size converted SOA integrated on a PLC platform will perform well in wavelength-division-multiplexing (WDM) applications.
FROM HAMILTONIAN SYSTEMS TO POISSON GEOMETRY

We introduce Hamiltonian systems and derive an important stability result, along with giving some physical motivation. We then move onto the generalization of these systems found in symplectic geometry. Next we consider symplectic geometry’s natural generalization, Poisson geometry. After giving some definitions we present the motivating example of the torqueless Euler equations. These motivate us to consider the abstract structure of Poisson geometry, but we first need to introduce some concepts from multivector calculus. Finally we arrive at some important results connecting symplectic geometry and Poisson geometry, including the Darboux-Weinstein theorem.
