COUPLED MISSION AND GNC ANALYSIS FOR SPACE ROBOTIC MISSIONS

Advance space missions, like orbital servicing missions, comprise a high degree of dependencies between subsystems and analysis procedures. Those dependencies are normally not very well represented by today's analysis tools as used for standard space missions. However, advanced space missions already required a high degree of confidence in early mission phases to keep the overall costs low. An efficient approach to achieve such confidence are highly flexible simulation environments, which allow coupled analysis of mission and GNC aspects at the same time already in Phase A of a project. A space robotics simulator will be presented, which combines mission analysis, GNC design and analysis, as well as realistic visualization of the scenario with OpenGL including detailed computation of environmental disturbances utilizing the geometrical knowledge within OpenGL. The ASTOS software provides the highly flexible mission analysis component and exports the real world representation to the GNC simulator, which is implemented in Simulink. The realistic visualization is done by VESTA. It computes the differential forces and moments due to solar pressure and air drag in high accuracy and faster than in real-time and feeds back this information to the GNC simulation. Moreover VESTA mimics the scenario as realistic as possible, which allows to verify the performance of visual sensors. Such sensors are essential for any rendezvous or planetary and lunar landing maneuvers and are normally difficult to test for complete space scenarios. Finally, an interface for a manipulator arm completes the list of feature. The combination of Simulink the most widely used software for GNC design and analysis with the COTS software ASTOS and the open source software VESTA provides an extremely flexible and powerful solution to investigate critical flight phases of advanced mission scenarios. The Space Robotics Simulator has been applied to the German Orbital Servicing Mission and has proven its added value for future space projects. Especially for close approach maneuvers, like berthing maneuvers, the coupled analysis is able to give full confidence in proposed strategies or to expose its weak points. The development of the Space Robotics Simulator has been co-funded by a grant of DLR/BMWi.
Complexity and organisational learning in NPD projects: An embedded case study

Project complexity is defined as an inherent characteristic of a project that results from the interrelations and the dynamics among its many parts, but also as something which is experienced by people working in projects, including both negative (in terms of difficulty to understand, to foresee and to keep under control) and positive aspects (emergence). The appropriate approaches and managerial actions to understand and address the increasing complexity of projects are a key determinant of the success of new product development (NPD), especially in the organisations where projects are the primary unit for innovation and competition, i.e. the project-based ones. This paper aims to provide new insights into how project-based organisations understand and face the complexity of their NPD projects from an organisational learning perspective. We conducted an exploratory, embedded case study research in a leading company in the shipbuilding industry. The contextual features of a project-based organisation allowed to investigate the dimensions of project complexity identified in literature (i.e. diversity, interdependence, dynamicity, uncertainty) and the patterns and mechanisms of organisational learning (processes, levels and issues linked to project constraints and distributed project management practices) within NPD projects embedded in a common organisational context. Results show that different levels in dimensions of complexity result in a prevalence of organisational learning processes. Overall, the complexity of NPD projects tends to bring to informal mechanisms of knowledge codification, to be properly shared and transferred in the upcoming projects. The results of the research can be of importance for both theory and practice as it provides a reference for the development of NPD projects in terms of definition, assessment and management of project complexity. Moreover, it suggests to innovation managers mechanisms and points of view to consider when dealing with the complexity of projects, especially considering the perspective of the organisational process that takes place within current and future NPD projects, aiming to realise the strategic objectives.
Ignazio Visco: Retirement saving and the payout phase – how to get there and how to get the most out of it

The implications of population ageing for financial markets have long been a subject of discussion for public authorities, financial intermediaries and academics. Over time we have become aware that ageing has a deep impact on the structure of financial markets and, at the same time, that this structure strongly affects the way in which demographic trends spread through the real economy. A leading role in this process has been played by the OECD.
A VIEW FROM THE PRESIDENT

The Ninth IMS/BS World Congress in Probability and Statistics was held in Toronto and is now part of our proud history. The First World Congress was in 1986 in Tashkent, with the ‘greetings’ of the great mathematician Andrey Kolmogorov who could not come in person due to illness. I believe he wasn't the only person not feeling well: the story goes that many people were not quite used to the Uzbekistan food.
A Non-Parametric Analysis

Competition and over-banking in the United Arab Emirates (UAE) indicates serious efficiency challenges facing the UAE banking sector prior to full compliance of the Bassel II capital accord in 2007. Using Data Envelopment Analysis (DEA), this paper investigates the relative efficiency measures. Six measures of efficiency performance are used: allocative, cost, pure technical, technical, scale and overall, using data from the annual financial reports from 1998 to 2002. Despite overall growing profits in the industry, results reveal evidence of over-banking and cost inefficiency in the money market. In particular, evidence suggests that regulatory and not managerial policy implications are attributed to poor cost efficiency results. Interestingly, and contrary to the benefits of economies of scale, the most efficient banks are not always the largest banks. Further evidence identifies contributory structural reasons for UAE banking inefficiency such as extensive capital adequacy ratios. At a time of growing global competition, data transparency and compliance with the World Trade Organisation, some individual banks need to address their financial positions to sustain high future profits.
Globalization and Top Income Shares

This paper presents a new piece of empirical evidence showing that access to the global market, either through exporting or through multinational production, is associated with a higher executive-to-worker pay ratio within the firm in the U.S. It then builds a model with heterogeneous firms, occupational choice, and executive compensation to analytically and quantitatively evaluate the impacts of globalization on within-firm inequality and top income shares. In the model the compensation of an executive grows with the size of the firm, while the wage paid to ordinary workers is determined in a country-wide labor market. As a result, the extra profits earned in the foreign markets benefit the executives more than the average worker. I calibrate the model to the U.S. economy and study the impacts of globalization on top income shares with simulations. Counterfactual exercises suggest that this new channel can potentially explain around half of the observed surge in top income shares in the U.S. between 1988 and 2008. JEL Codes: E25 F12 F62 J33
The Buyer-Supplier Exchange in the Presence of Design, Logistic and Quality Interactions: Results of an Empirical Research

On the basis of empirical research on a sample of Italian plants, this study: ' analyses the relationships between advanced buyer-supplier operational interaction practices (design link, logistic link, quality link) and the basic options of the buyer's purchasing strategy, such as: sources selection criteria, supply base reduction policies, long-tenn perspectives granted to suppliers (stability of procurement); ' compares these operational practices and purchasing policies in different performing plants. In other words, this study verifies if advanced buyer-supplier interaction practices and "cooperative" supply management policies exhibit a predictive validity of the plant performances. The survey involved 497 respondents in 52 plants of two industries (electronic and mechanical). The study demonstrates that the establishment of an advanced operational link with sources significantly influence the basic option of the buying firm's purchasing strategy. In addition, it demonstrates that better performing plants exhibit a higher level of design and logistic interactions and a better use of long-temi supply agreements with sources.
Customers Intention Towards Green Hotel Practice in Malaysia

Tourism industry in Malaysia has experienced continued growth due to Malaysia’s beautiful natural assets over decades. Tourism is largely depending on the clean environment, so the issues of operational hotel waste cannot be ignored. It is expected that customer behaviour while staying at the hotel can produce tonnes of waste. As a result, becoming a green customer is a step to cope with this problem. Green customers are people who committed about going green that will help to create a better environment. This concept is widely used in other countries but “limited” in Malaysia especially on green customers’ intention. Therefore, the theory of planned behaviour has been tested to define which factor is influencing the customer intention to practice green while staying at the hotel. This paper aimed to define which measurement items represent the factors of (attitude, subjective norm, perceived behaviour control and overall image). Confirmatory Factor Analysis (CFA) is used to validate the measurement model. The questionnaires are distributed and 210 respondents are received. The respondents are focussed to hotel customers in Malaysia. Data analysing is using Analysis of Moments Structures (AMOS) to confirm the unidimensional, validity and reliability for measurement model. Findings indicate most respondents perceived positive perception toward participating in green campaign favourably affect to practice green while staying at the hotel while the other factors were found no significantly generalise the finding. This highlighted the finding as to the emerging of group green customer in Malaysia still a long way to go.

FABRICATION AND TESTING OF DOUBLE- POLE FOUR-THROW SWITCH WITH N-MOSFETS

In this research work, a Double-Pole Four-Throw (DP4T) switch has been fabricated using n-MOSFET. This switch is beneficial in terms of the MIMO system and reduces the size, power, and hardware structure. This designed DP4T switch operates within the widely used frequency band up to 10 GHz applications. This makes the RF switch accomplished of selecting data streams to/from the two antennas for transmitting/receiving processes simultaneously. The simulated result gives the return loss 15.90 dB, insertion loss 1.68 dB, and off-isolation loss 39.34 dB, and for measured (after fabrication) these values are 11.96 dB, 2.53 dB, and 30.72 dB, respectively. It uses the MOSFETs, hence, it is also suitable for low power devices and nanotechnology devices.
Performance Evaluation of Real Time Spectrum Sensing in Cognitive Radio Networks

: Spectrum scarcity and congestion has motivated new communication paradigm to exploit the existing wireless spectrum opportunistically. An emerging technology based on Cognitive Radio (CR), has the potential to maximize spectrum usage efficiently. A key feature of cognitive radio technology is spectrum sensing, which is the detection of unused or vacant frequency bands i.e. spectrum holes. The paper presents an energy detection technique through Power Spectral Density (PSD) estimation for real time sensing of occupied and vacant spectrum bands. The Neyman-Pearson hypothesis is considered for detecting the presence and absence of user signal, over a bandwidth of 5MHz, with probability of detection and probability of false alarm as metrics. The real time implementation of algorithm has been done on Wireless open Access Research Platform (WARP) board with FPGA Virtex 6. The received Welch PSD estimates from the proposed technique is then used in energy detection process for identifying spectrum holes that can be used by CR systems to access opportunistically. The performance of various modulation schemes viz BPSK, QPSK and QAM are presented and discussed for improved signal quality.
In Vitro Detection of Biofilm Formation by Uropathogenic Escherichia Coli in A Tertiary Care Hospital

Introduction: Biofilm are surface associated bacterial communities surrounded by a matrix of exo-polymers and are responsible for development of clinical infections.Urinary tract infections are considered to be one of the most common bacterial infections.Uropathogenic strains of Escherichia coli account for 70-95% of the UTIs. The bacteria enclosed within the biofilm are extremely resistant to treatment. Objective: To study Biofilm formation of Uropathogenic Escherichia coli by Tube method and Tissue Culture Plate method.

Out of 200 samples, 100 isolates of Uropathogenic Escherichia coli were included in this study. They were identified by standard microbiological procedures. These isolates were subjected to biofilm production by Tube method and Tissue culture plate method. Results: Out of 102 Uropathogenic Escherichia coli isolates 40.19% were biofilm producers by Tube Method and 47.05% by Tissue culture Plate Method. Conclusion: Tube Method correlated well with Tissue Culture Plate method for strong biofilm detection in Uropathogenic Escherichia coli.
Integration of Fluid Dynamics and Solid Mechanics Models for FSI Simulation using GPU-based SPH Framework

In many engineering fields, pressure from fluid flow causes major deformation in the structure. This interaction is Fluid Structure Interaction (FSI). Among the many ways to describe the FSI are the Arbitrary Lagrangian Eulerian (ALE) typical. However, ALE has disadvantages in phenomena such as large deformation of the structure or rapid flow of fluid [1]. On the other hand, the Smoothed Particle Hydrodynamics (SPH) method, which is a Fully Lagrangian method, has advantage to this interpretation. FSI is a method used in many areas of nuclear engineering, such as the behavior of the fuel assembly flowing axially in the direction of coolant, pressure loads on the vessel internal structures in PWR during a LOCA, blowdown, Flow-Induced Vibration (FIV), flow-induced fluid-elastic vibrations, sloshing of pressurizer on a nuclear ship, rupture or swelling of fuel rods and InVessel Retention (IVR) failed due to broken vessel. This is because accurately simulating the interaction of fluid and structure can help design the plant and cope with accidents. In this study, the interaction of fluid with structure was added to the SOPHIA code to implement the FSI. The SOPHIA code is an SPH-based parallelization multiphysics code developed by Seoul National University [2]. To validation this, Benchmark experiment and numerical simulation were compared with simulation through SOPHIA code with FSI added.
REAL TIME STATISTICALLY BOUNDARY DETECTION

The first task for object detection and recognition is image segmentation. This process is initialized with boundary detection. In this paper we propose a boundary detection method based on standard deviation value of intensity within the window. We assume that the low value is similar colour where the computation process occur on the same object. While the high value, the computation process will occur on the object ’ s boundary or edge. In this research we compare to other methods to evaluate the performance of proposed method. The experimental result, by using window size of 3  3 pixels, our method ’ s computation time is 66.54 ms and using window size of 5  5 pixels, the computation time is 67.39 ms. Video rate is 15 fps. Processing with the proposed method yields less noise compared to other method, both for colour and grayscale processing.

The songs will consist chord, rhythm and melody at the same time. We will introduce the framework of our system and the kernel components of each part. In experiment, our system successfully generates many wonderful songs and convince a human about 30% of the time that it’s composed by human-being during the Turing test
Model driven testing distributed environment monitoring system

Distributed environment monitoring system is more and more widely used, especially the design and verification of embedded system in environmental monitoring is the guarantee of successful use of environmental monitoring. In this paper we demonstrate how test-case prioritization can be performed with the use of model-checkers. For this, different well known prioritization techniques are adapted for model-based use. New property based prioritization techniques are introduced. In addition it is shown that prioritization can be done at test-case generation time, thus removing the need for test-suite post-processing. Several experiments for embedded systems are used to show the validity of these ideas.

A predictive model of bacterial cell division

A mathematical model of the formation and contraction of the prokaryotic Z-ring in vivo was developed, based on the polymerisation and membrane anchor binding activity of the FtsZ protein as measured in vitro. From a set of kinetic parameters that are estimated from the experimental literature, the model, which is referred to as Critical Accumulation of Membrane-bound FtsZ Fibres (CAM-FF), predicts one of three cell division outcomes: i) division proceeds to completion, ii) division is initiated but stalls prior to completion, and iii) division is not initiated. CAM-FF was validated by the accurate prediction of the effect of deletion of the membrane anchor proteins ZipA and FtsA, and was used to predict an order of efficiency of the biochemical targets for antibacterial drug design as follows: FtsZ polymerisation > ZipA/FtsA availability > FtsZ GTP-binding. The temperature-sensitivity of the ftsZ84 mutant was also analysed using CAM-FF and it was found that an acquired ATPase activity of the FtsZ84 protein (FtsZ G105S) could explain the temperature-sensitivity of cell growth. At lower temperatures where the ATPase activity is low, a functional Z-ring is able to form and contract. However, at 42 °C the increase in the ATPase rate causes the Z-ring to disassemble and cell division is inhibited. On purification of the FtsZ G105S mutant protein, a significant ATPase activity was observed in vitro that was absent in the wild-type FtsZ protein. Therefore, the ATPase activity is not an experimental artifact, as was previously thought. The ZapA and ZipA roteins were also purified, and the FtsA protein was overexpressed for subsequent purification, in preparation for crystallography and in vitro cell division reconstitution studies. A set of linear DNA molecules with defined length and GC content was designed and produced for the investigation of polymer hysteresis in flow.
Service Quality and Customer Satisfaction: Experience of Customers’ in Postal Service

Providing great quality service is essential for a sustainable competitive advantage in today’s aggressive business environment. Organization’s success could positively influence by customer satisfaction. This study tried to examine the relationship between service quality elements towards customer satisfaction. Modified SERVQUAL model by Parasuraman et al. has been used to measure the four service quality dimensions. Data collection in this research was used quantitative method. Self-administered questionnaire focusses on customers of Pos Malaysia in Kuala Terengganu. Convenience sample of 322 Pos Malaysia customers were collected. Pearson correlation analysis reveals that all four service quality elements were positively associated with customer satisfaction with moderate correlation. Responsiveness and reliability were discovered to influenced customer satisfaction most compared to other elements. Therefore, this finding suggests that service industries particularly postal services should cultivate the key service quality elements thoroughly in order to enhance customers’ satisfaction without overlooking the remaining dimension.
Testing for Hysteresis in Unemployment in the Belgian Regions

As a consequence of the economic crisis, unemployment figures are soaring. Given the history of Belgian unemployment, it is a concern that these unemployed people will be lost for the labour market in the future. Albeit this observation on the Belgian level, the question is whether this persistence is also found in the three Belgian regions. In this paper regional unemployment series are analysed using different tests for the presence of hysteresis.
Mating system and two types of gametogenesis in the fresh water diatom Ulnaria ulna (Bacillariophyta)

Sexual reproduction and mating system of the freshwater diatom Ulnaria ulna (Nitzsch) Compère were studied by using clonal cultures. Mating system of the species involves homoand heterothallic modes of reproduction; and both male and female clones were capable of homothallic reproduction. Two types of gametogenesis corresponding to two mating types were investigated. Analysis of the crossing table, gamete morphology, and sex distribution in the progeny resulted from intraclonal reproduction provided evidences that anisogamy and two mating types were determined in U. ulna genetically; male and female clones were heteroand homogametic correspondently. Specific active movement of male gametes caused by the formation and retraction of pseudopodia-like structures on the gamete surface was described. The absence of reproductive isolation between clones gathered from geographically distant populations suggests continuity and broad distribution of the species. K e y w o r d s : Ulnaria ulna, mating system, sexual reproduction, gametogenesis, gametes movement, reproductive isolation.
