Analysis of a five phase electrical drive for the propulsion of all electric aircraft
Venue: 2016 AEIT International Annual Conference (AEIT)

In order to reduce the environment pollution and the oil dependence of the aeronautical industry, in the last years more electric or all electric aircraft are considered the most effective solutions for next future. As well known, an all electric aircraft uses a propulsion system based on electric motors in addition to the on board electromechanical actuators. For these new propulsion systems the presence of fault tolerant architectures is mandatory, together with high reliability and robustness of control. The aim of this paper is to point out some sizing considerations of a brushless drives based on a five phase permanent magnet synchronous motor devoted to the electric propulsion of a civil aircraft for the general aviation. With reference to a case study of a two propeller four seat aircraft, starting from the requested mechanical and dynamic performance, the main sizes of two sets of motors are obtained. A comparison is carried out among features and performance of the designed motors, with specific reference to power density and external diameter and length.
Cord blood collection and processing with hydroxyethyl starch or non hydroxyethyl starch.
Venue: Cytotherapy

Collection and processing characteristics influencing quality of cord blood (CB) units play an essential role to cord blood banks (CBBs) At many CBBs, volume reduction is performed using hydroxyethyl starch (HES) and the Sepax (Biosafe) automated cell processing system. Due to the withdrawal of HES from the European market, a validation of the nonHES protocol was performed.  This partially retrospective study identified CB characteristics such as gestational age and CB volume/cell count correlated with higher quality. For the nonHES validation, CB was analyzed for total nucleated cell (TNC) mononuclear cell (MNC) recovery, hematocrit (HCT) and colony forming units (CFUs) Viabilities of CD34( and CD45( cells were determined by 7 aminoactinomycin D (7 AAD) and AnnexinV (AnnV) staining and compared for 21 mL and 42 mL buffy coat (BC) samples applying the HES/nonHES protocol.  Factors affecting the potency of CB transplants were the gestational age and the volume reduction to a defined BC volume. High initial cell counts and CB volumes correlated negatively with post processing TNC recovery for lower BC volumes. Post processing HES and nonHES results were comparable, but nonHES revealed a significantly lower post thaw recovery of viable CD34( cells measured by 7 AAD/AnnV (21 mL: 45.4 16.4% 42 mL: 67.3 14.5% as compared with HES (21 mL: 72.7 14.4% P 0.0164; 42 mL: 83.4 14.7% P 0.0203) DISCUSSION Due to the lower post thaw CD34( cell viability (AnnV( /7 AAD( for nonHES samples, the use of HES is recommended, ideally combined with a high BC volume. The post processing HCT has no statistically significant impact on the post thaw CD34( cell viability (AnnV( /7 AAD(
Rotary Type Electromagnetic Power Generator Using a Cardiovascular System As a Power Source for Medical Implants
Venue: IEEE/ASME Transactions on Mechatronics

Power harvesting devices have received attention as power supplies for implantable medical devices. Power harvesting technologies can overcome the limitation of a battery, such as limited battery lifetime and repeated surgical interventions. However, micropower generators do not meet the energy requirements of medical implants such as neural recording, implantable hearing aids, and implantable wireless sensors. They require an electrical power from 1 to 10 mW. This paper introduces an electromagnetic power generator using blood flow and blood pressure to drive an implanted medical device. The fabricated power generator, which is composed of a tiny rotor with magnets and external coils with ferrite cores, operates within a wide blood pressure range from 6.75 to 54.75 mmHg. In addition, the total volume and weight of the generator are 3.16 cc and 24 g, respectively. Using animal and mock up tests, we verified the ability of the self powered device to drive the medical implants. In the animal test, we utilized a blood pump to control the blood flow and blood pressure. The generator generated a maximum electrical power of 3.4 mW (conversion efficiency of 1.04% at a blood pressure drop of 54.75 mmHg and blood flow of 2.68 L/min.
SEED: A Scalable Approach for Cyber Physical System Simulation
Venue: IEEE Transactions on Services Computing

Simulation is critical when studying real operational behavior of increasingly complex Cyber Physical Systems, forecasting future behavior, and experimenting with hypothetical scenarios. A critical aspect of simulation is the ability to evaluate large scale systems within a reasonable time frame while modeling complex interactions between millions of components. However, modern simulations face limitations in provisioning this functionality for CPSs in terms of balancing simulation complexity with performance, resulting in substantial operational costs required for completing simulation execution. Moreover, users are required to have expertise in modeling and configuring simulations to infrastructure which is time consuming. In this paper we present Simulation EnvironmEnt Distributor (SEED) a novel approach for simulating large scale CPSs across a loosely coupled distributed system requiring minimal user configuration. This is achieved through automated simulation partitioning and instantiation while enforcing tight event messaging across the system. SEED operates efficiently within both small and large scale OTS hardware, agnostic of cluster heterogeneity and OS running, and is capable of simulating the full system and network stack of a CPS. Our approach is validated through experiments conducted in a cluster to simulate CPS operation. Results demonstrate that SEED is capable of simulating CPSs containing 2,000,000 tasks across 2,000 nodes with only 6.89x slow down relative to real time, and executes effectively across distributed infrastructure.

The mediating role of organizational identification in the relationship between qualitative job insecurity, OCB and job performance

Employees need to feel secure to perform their job effectively, therefore job insecurity has an effect on organizational citizenship behaviour (OCB) and job performance; however, some organizational attitudes may reduce these negative effects. The purpose of this paper is to investigate the mediating role of organizational identification (OID) as a process underlying the relationship between qualitative job insecurity, OCB and job performance.  Using social exchange theory (SET) and social identification theory (SIT) this study reports the responses of 201 white and blue collar Italian employees. Data were collected through a self report questionnaire that used standard scales on qualitative job insecurity, OID, OCB and job performance.  Results of structural equation modelling revealed that the effect of job insecurity on OCB and job performance was completely mediated by OID. Fit indices of mediated model are very good and indirect effects, by bootstrap.
Employee Resilience and OCB: Mediating Effects of Organizational Commitment

With increased popularity of positive psychology, there is a greater emphasis on exploring positive human resource strengths to address the workplace challenges and augment organizational performance. Previous research suggests that resilience positively relates to desired employee attitudes, behaviours, and performance such as organizational citizenship behaviour (OCB) However, it would be intriguing to understand the underlying mechanism of resilience OCB relationship. Towards this, the study examines the mediating role of organizational commitment. In the light of identified research gaps, the study explores the mechanism of the relationship between resilience and OCB in the context of Indian organizations. The study sample comprised employees (N 345) working in the manufacturing industries of Uttarakhand and Himachal Pradesh in India. Data were collected with the help of self administered questionnaires through systematic random sampling. A model was developed and tested in which the effects of resilience on OCB were hypothesized to be mediated by organizational commitment. The hypotheses testing was done using hierarchical multiple regression and for testing the mediating effects, bootstrapping in SPSS was used. The results provide empirical evidence for the positive relationship between resilience and OCB. Also, the results emphasize that resilience influence organizational commitment as well. As hypothesized, results have also supported the mediating effect of organizational commitment in the relationship between resilience and OCB, explaining the underlying mechanism of resilience OCB relationship. The mediation is partial which means that resilience influences OCB directly as well as indirectly through organizational commitment. The study offers significant advancements for both resilience and OCB research. The results also offer direction to organizations which desire to stimulate and maintain employee outcomes in their organizations for competitive advantage. Employee outcomes in organizations can be improved by developing resilience among its employees. Implications of promoting resilience at workplace are discussed.
Team OCB, leader charisma, and organizational change: A multilevel study

This study examines individual level origins of team organizational citizenship behaviors (OCB) Building on the literature on trust and social exchange theory, we hypothesize that individual level leader charisma is indirectly related to team OCB through individual level trust in leader. Additionally, we propose that the positive relationship between leader charisma and trust in leader is stronger under conditions of high organizational change. Based on data from 142 team members and 33 leaders, results reveal an indirect bottom up relationship between individual level leader charisma and team OCB through trust in leader. High change impact at the team but not at the individual level facilitates the positive relationship of leader charisma with trust in leader. The findings show how individual level phenomenon can contribute to the emergence of team level OCB.
Voice Modulation: A Window into the Origins of Human Vocal Control?
Venue: Trends in Cognitive Sciences

An unresolved issue in comparative approaches to speech evolution is the apparent absence of an intermediate vocal communication system between human speech and the less flexible vocal repertoires of other primates. We argue that humans' ability to modulate nonverbal vocal features evolutionarily linked to expression of body size and sex (fundamental and formant frequencies) provides a largely overlooked window into the nature of this intermediate system. Recent behavioral and neural evidence indicates that humans' vocal control abilities, commonly assumed to subserve speech, extend to these nonverbal dimensions. This capacity appears in continuity with context dependent frequency modulations recently identified in other mammals, including primates, and may represent a living relic of early vocal control abilities that led to articulated human speech.
SDN Guard: DoS Attacks Mitigation in SDN Networks
Venue: 2016 5th IEEE International Conference on Cloud Networking (Cloudnet)

Software Defined Networking (SDN) has recently emerged as a new networking technology offering an unprecedented programmability that allows network operators to dynamically configure and manage their infrastructures. The main idea of SDN is to move the control plane into a central controller that is in charge of taking all routing decisions in the network. However, despite all the advantages offered by this technology, Deny of Service (DoS) attacks are considered a major threat to such networks as they can easily overload the controller processing and communication capacity and flood switch CAM tables, resulting in a critical degradation of the overall network performance. To address this issue, we propose in this paper SDN Guard, a novel scheme able to efficiently protect SDN networks against DoS attacks by dynamically (1) rerouting potential malicious traffic, (2) adjusting flow timeouts and (3) aggregating flow rules. Realistic experiments using Mininet show that the proposed solution succeeds in minimizing by up to 32% the impact of DoS attacks on~the controller performance, switch memory usage and control plane bandwidth and thereby maintaining acceptable network performance during such attacks.
Convex Hull Watchdog: Mitigation of Malicious Nodes in Tree Based P2P Monitoring Systems
Venue: 2016 IEEE 41st Conference on Local Computer Networks (LCN)

Monitoring the global state in peer to peer networks through decentralized mechanisms allows targeted optimization and improvement of the peer to peer network. However, malicious nodes could aim to distort the process of gathering the global state through monitoring. In this paper we propose DOMiNo, a security solution for tree based peer to peer monitoring mechanisms. It passively listens to incoming events, e.g. data, and rates its suspiciousness based on outlier detection, structural verification and sanity check mechanisms. For our main objective, which is to limit the monitoring error of the desired global view, we performed an extensive evaluation. Evaluation shows tolerance with normal fluctuations but effective filtering of outliers, that severely influence the global view. As our watchdog solution operates passively, we do not add any costs nor create new surface for attacks to the monitoring system.
Human Visual System as a Double Slit Single Photon Interference Sensor: A Comparison between Modellistic and Biophysical Tests
Venue: PloS one

This paper describes a computational approach to the theoretical problems involved in the Young's single photon double slit experiment, focusing on a simulation of this experiment in the absence of measuring devices. Specifically, the human visual system is used in place of a photomultiplier or similar apparatus. Beginning with the assumption that the human eye perceives light in the presence of very few photons, we measure human eye performance as a sensor in a double slit one photon at a time experimental setup. To interpret the results, we implement a simulation algorithm and compare its results with those of human subjects under identical experimental conditions. In order to evaluate the perceptive parameters exactly, which vary depending on the light conditions and on the subject's sensitivity, we first review the existing literature on the biophysics of the human eye in the presence of a dim light source, and then use the known values of the experimental variables to set the parameters of the computational simulation. The results of the simulation and their comparison with the experiment involving human subjects are reported and discussed. It is found that, while the computer simulation indicates that the human eye has the capacity to detect the corpuscular nature of photons under these conditions, this was not observed in practice. The possible reasons for the difference between theoretical prediction and experimental results are discussed.
Holocene delta evolution and sediment flux of the Pearl River, southern China

Delta progradation and sediment flux of the Pearl River Delta (PRD) southern China, during the Holocene are presented based on analyses of borehole data on the delta plain. Results indicate that the delta prograded into the drowned valley because of early Holocene inundation from 9 to 6 cal ka BP, as sea level rise decelerated. The sea level reached its present level at about 6 cal ka BP and, as a consequence, a large portion of the drowned valley was covered by the estuary, with more than 160 rock islands and platforms. The scattered landmasses promoted active deposition and acted as deposition nuclei during deltaic evolution. Consequently, apart from exhibiting a general tendency towards progression, PRD development occurred less regularly over time and space because of deposition around island boundaries. During the last 2 ka, mainly because of significantly increased human activities, which have trapped sediments in the encircled tidal flats along the front of delta plains, the shoreline has advanced rapidly. Estimated sediment fluxes for the three periods (9 6, 6 2 and 2 0 cal ka BP) based on the sediment volume analysis, were 17 25, 22 30 and 44 58 million t a( 1) respectively.
Recent advances in cellulose and chitosan based membranes for water purification: A concise review.
Venue: Carbohydrate polymers

Recently membrane technology has emerged as a new promising and pervasive technology due to its innate advantages over traditional technologies such as adsorption, distillation and extraction. In this article, some of the recent advances in developing polymeric composite membrane materials for water purification from natural polysaccharide based polymers namely cellulose derivatives and chitosan are concisely reviewed. The impact of human social, demographic and industrial evolution along with expansion through environment has significantly affected the quality of water by pollution with large quantities of pesticides, minerals, drugs or other residues. At the forefront of decontamination and purification techniques, we found the membrane materials from polymers as a potential alternative. In an attempt to reduce the number of technical polymers widely used in the preparation of membranes, many researchers have reported new solutions for desalination or retention of organic yeasts, based on bio renewable polymers like cellulose derivatives and chitosan. These realizations are presented and discussed in terms of the most important parameters of membrane separation especially water flux and retention in this article.
Diagnostic validity of self reported measures of sleep bruxism using an ambulatory single channel EMG device.
Venue: Journal of prosthodontic research

Self reported measures have been widely used to indicate the presence of possible and probable sleep bruxism (SB) in both research and clinical situations. However, few studies have attempted to assess the diagnostic validity of this approach. The aim of this study was to estimate the diagnostic validity of self reported measures of SB using an ambulatory single channel electromyographic (EMG) device.  A total of 115 participants were enrolled and examined by standardized Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) including two questions related to SB: self reported SB and morning jaw symptoms. An ambulatory single channel EMG device (GrindCare3(tm) Medotech A/S) was used for measuring jaw muscle EMG activity during sleep for seven consecutive nights. Cut off values for different measures of EMG activity (average, maximum and minimum) and the coefficient of variation (CV) were selected to divide participants into two groups, with higher or lower EMG activity or CV values. The sensitivity and specificity for each question and combination of them were calculated.  Self reported SB had the highest sensitivity (compared with morning jaw symptoms) for all measures of EMG activity and CV, although the values were low to modest (average: 76.0% maximum: 76.9% minimum: 77.3% CV: 61.0% The specificity was low for both the questions related to the different measures of EMG activity and CV (35.1 52.4%  This study indicated that the diagnostic validity of self reported measures of SB was low to modest using an ambulatory EMG device assessment as a reference. Using only self reported measures for the assessment of SB may not have a high validity, which should be taken into consideration in the clinical evaluation of patients.
The Promotion of ASEAN Regional Integration Through Open and Distance Higher Education

Technically, these three concerns may be addressed by Open, Distance and eLearning (ODeL) strategies. ODeL, by definition, is inclusive. ODeL programs transcend geographic boundaries and may be made available to learners from all ten countries in the ASEAN Region. Authentic open education is not bound by cumbersome academic traditions and may be nimbly designed to respond to the needs of the current labor market. Furthermore, regionally recognized ODeL certification and degrees will allow mobility among their holders to practice across the region. Additionally, ODeL provides innovative and alternative educational delivery systems for the marginalized such as online learning, blended learning, flipped classes and Massive Open Online Courses (MOOCs) By nature, these options should be industry driven and are thus responsive to labor markets. Using online delivery systems for capacity development make ODeL innovative and ubiquitous.
