ADVANCED SIGNAL PROCESSING METHODS FOR EVALUATION OF HARMONIC DISTORTION CAUSED BY DFIG WIND GENERATOR

Intensified growth of wind power generation emphasizes the need for detailed evaluation of disturbances caused by wind generators. The paper presents a physical model of doubly fed induction generator (DFIG) connected to low voltage distribution grid. Harmonic distortions caused by wind generator under various operational conditions regarding wind speed, active and reactive power have been investigated. Fourier transform, ESPRIT and Prony analysis have been applied simultaneously to evaluate distortion levels.
Optimal Strategies for Phase Control of Wave Energy Devices

Phase control has previously been proposed for increasing energy output from wave power devices, and latching strategies have been tested for point absorbers and for pneumatic devices. Theoretical studies to determine optimal control strategies have not, however, been carried out until now. This paper provides a framework for the analysis of the problem, based essentially on L. S. Pontryagin's Maximum Principle. It indicates stable computational techniques for finding optimal solutions and summarize the results of studies on two devices - a point absorber and an oscillating water column.
Probabilistic Analysis of Nonlinear Structures Subjected to Transient Loads. Part 1.

Abstract : A technique for the analysis of reliability in linear and nonlinear systems that can be modeled as single-degree-of-freedom (SDF) structures is investigated and established. Transition probabilities are established using conditional probability and problems for stationary and nonstationary input are shown. Methods for computational enhancements are investigated. Multiple point failure analysis of multiple-degree-of-freedom (MDF) systems is addressed separately. Peak responses are expanded in a series involving the input and systems parameters and moments of the peak response are determined. Margins of survival are established using random failure levels and the probability of survival is computed. A second method using the equations of a numerical technique to form the joint probability density of the response measures is also presented. (Author)
Tactical Team Resource Management Effects on Combat Mission Training Performance.

Abstract : This report describes Tactical Team Resource Management (T2RM) behaviors exhibited by Special Operations Forces MC-I 30P aircrews (aircraft commander, copilot, left navigator, right navigator, flight engineer, loadmaster, and communication specialist) as they planned and executed a simulated combat mission during annual simulator refresher training Five crew process elements (situational awareness; function allocation; time management; tactics employment and communication) and several indices if mission performance were recorded for five specific mission phases (mission planning, low-level operations, airdrop, air refueling, and infiltration/exfiltration). Team process overall was highly related to mission performance (r = .86). All of the crew process elements except communication were also predictive of overall crew performance. The relative predictive value of the specific process elements varied across the five mission phases, but the predictive value of communication was consistently low. Several structural and crew demographic variables were also explored with crew size, focus, and squadron affiliation appearing to have large effects. We summarize our main findings within the context of past cockpit resource management (CRM) research and MC-13P operations. We conclude the report with several recommendations for the conduct of ORM training based on our findings and observations.
Custom Ontologies for Expanded Network Analysis

Abstract : This paper discusses a new approach to answering Requests for Information (RFIs) from military commanders, intelligence analysts, individual soldiers and others received by reach-back information and intelligence collection repositories. This new approach avoids the previous ideals of either searching out a set of a thousand documents or building one large all-encompassing ontology and instead embraces the concept of custom ontologies based on each users query and returns to that user a concise and organized knowledge set along with visualizations that invite exploration and facilitate assimilation.
The Eect of Mechanical Loading on the Frequency of an Oscillator Circuit

We investigate the effect of mechanical strain on the frequency of an electronic oscillator embedded in an integrated circuit. This analysis is aimed at explaining a 1% inaccuracy in the oscillator frequency under test conditions prescribed by a leading supplier of semi-conductor devices. During the test the package containing the oscillator was clamped to a circuit board by mechanical pressure. By considering the nature of the oscillator we show that tensile strains of the order of 10^-4 could explain the observations via the piezoresistance effect. Both a simple one-dimensional analysis based on the beam equation and an elastic finite element simulation show that strains of this magnitude can be generated during the test.
Full A Call for Consensus in Defining Efficacy in Clinical Trials for Opioid Addiction: Combined Results from a Systematic Review and Qualitative Study in Patients Receiving Pharmacological Assisted Therapy for Opioid Use Disorder

Background Given the complex nature of opioid addiction treatment and the rising number of available opioid substitution and antagonist therapies (OSAT), there is no ‘gold standard’ measure of treatment effectiveness, and each successive trial measures a different set of outcomes which reflect success in arbitrary or opportune terms.We sought to describe the variation in current outcomes employed across clinical trials for opioid addiction, as well as determine whether a discrepancy exists between the treatment targets that patients consider important and how treatment effectiveness is measured in the literature. Methods We searched nine commonly used databases (e.g. EMBASE, MEDLINE) from inception to August 1, 2015. Outcomes used across trials were extracted and categorized according to previously established domains. To evaluate patient reported goals of treatment, semi-structured interviews were conducted with 18 adults undergoing methadone treatment. Results We identified 60 trials eligible for inclusion. Once outcomes were categorized into eight broad domains (e.g. abstinence/substance abuse), we identified 21 specific outcomes with furthermore 53 subdomains and 118 measurements. Continued opioid use and treatment retention were the most commonly reported measures (46%, n=28). The majority of patients agreed that abstinence from opioids was a primary goal in their treatment, however they also stressed goals under-reported in clinical trials. Conclusion There is inconsistency in the measures used to evaluate the effectiveness of OSATs. Individual and population level decision making is being guided by a standard of effect considered useful to researchers yet in direct conflict with what patients deem important.

E-Metering and Fault Detection in Smart Water Distribution Systems using Wireless Network

Water distribution system is a network that supplies water to all the consumers through different means. Proper means of providing water to houses without compromising in quantity and quality is always a challenge. As it is a huge network keeping track of the utilization is difficult for the utility. Hence through this project we come up with a solution to solve this issue. Current technologies like Low Power Wide Area Networks, LoRa and sensor deployment techniques have been in research and were also tested in few rural areas but issues due to hardware deployment and large scale real time implementation was a challenge hence through this system we aim to create and simulate a real time scenario to test a sensor network model that could be implemented in large scale further. This project aims in building a wireless sensor network model for a smart water distribution system. In this system there is bidirectional communication between the consumer and the utility. Each house has a meter through which the amount of water consumed is sent to the utility board. The data has two fields containing the house ID and the data (water consumed); it is being sent to the data collection unit (DCU) which in-turn sends it to the central server so that the consumption is monitored in real time. All this is simulated using NETSIM and MATLAB
Crowdsourcing for Innovative Knowledge: effects of Knowledge Synthesis and Centralised Communication Position

ABSTRACT As innovation is increasingly generated via crowdsourcing, factors that enable or impede collective innovation deserve a closer examination. This study advances the literature by examining the roles of knowledge synthesis and communication positions in open innovation challenges. Analysing 3,200 posts generated from 21 organisation-sponsored online crowd-based open innovation challenges. This study showed that when knowledge contributors occupy centralised positions in online knowledge collaboration, they are less likely to generate innovative knowledge, and the benefit obtained from synthesised knowledge tends to be hampered by the contributor’s centralised position in the interaction. This study adds a new dimension to explaining crowdsourcing for innovation by incorporating a perspective of communication position into crowdsourcing and open innovation research. It also sheds light on the practice of crowdsourcing by highlighting the design of platforms that can promote the synthesis of crowd members’ shared knowledge while encouraging diverse voices from non-centralised members of the crowd.
MICA - Mobile Internet Connected Assistant

It is important that assistive devices adapt to the users personal needs and wishes. Technical and form designers need specialized knowledge about the user, that is why we need to build up knowledge and cooperation with the user. This means that we make tests in real environments such as homes and nursing homes. Users are diverse which means that they need diverse technical applications. Many users need wheelchairs in several life situations. In the MICA (Mobile Internet Connected Assistant) project we study an autonomous wheelchair that has the capability to navigate in complex environments. The vehicle is connected to the Internet using wireless technology. That makes it possible to tele-operate the wheelchair and support a user over a physical distance. Since the system gives an arbitrary user the ability to remote operate the vehicle it is possible for an assistant or relative to control, help or assist in difficult situations. The wheelchair has an Internet browser support where anyone can see live video taken from the camera onboard the vehicle. The technical aspect of the research focuses on autonomous navigation and how to develop technique to assist disabled users in their home environment. Design students from the University of Lapland suggested different devices to use the automatic technology of MICA. The aim was to correspond to different needs of diverse people. A second challenge for the devices are to fit the users, personalize them so that devices respect the individual and give life support and keeps the identity of the users. This challenge began to clear with knowledge about the single user.
Process assessment for the extended enterprise during early product development using novel computational techniques

Manufacturing practices have evolved over the last quarter of a century in the light of changes to manufacturing technology and demand. To sustain this growth companies are increasingly focused on better design and quicker time to market, to stay one step ahead of the competition. Expanding technology capabilities have included microcomputers and telecommunications. In particular the Internet has allowed businesses to trade with an extended customer base, resulting in a greater demand and perpetuating the cycle. To mirror this statement, businesses are looking increasingly far and wide for suitable suppliers. This work identifies a need in the market for an Internet based supplier selection function, during early product development. The development of this work differs significantly from other process selection methods by the use of the Internet to link companies. It has advantages for product development relating to the scope of the opportunities, diversity of possible manufacturing operations and rapid assessment of processes. In particular the system can be broken down into two main functions. Process Selection (PS) and Factory Selection (FS). The PS method presented enables many processes to be modelled, in multiple organisations for a single product. The Internet is used to gain access to supplier facilities by adopting the same principles as on-line banking, or shopping, for data input and access. The results of these assessments are retained by the system for later analysis. The FS method utilises this data to model and compare supplier attributes, allowing the user to manipulate the data to fit their requirements. Testing of the system has proved encouraging for many operations, including Injection Moulding and CNC Machining. It can be concluded that the identification of manufacturing operations outside the remit of companies' normal scope will create further opportunities for supplier integration.

The calcilytic drug Calhex-231 ameliorates vascular hyporesponsiveness in traumatic hemorrhagic shock by inhibiting oxidative stress and mitochondrial fission

Background The calcium-sensing receptor (CaSR) plays a fundamental role in extracellular calcium homeostasis in humans. Surprisingly, CaSR is also expressed in non-homeostatic tissues and is involved in regulating diverse cellular functions. The objective of this study was to determine if Calhex-231 (Cal), a negative modulator of CaSR, may be beneficial in the treatment of traumatic hemorrhagic shock (THS) by improving cardiovascular function, and investigated its relationship to oxidative stress and the mitochondrial fusion-fission pathway. Methods Rats that had been subjected to traumatic hemorrhagic shock were used as models in this study. Hypoxia-treated vascular smooth muscle cells (VSMCs) were also used. The effects of Cal on cardiovascular function, animal survival, hemodynamic parameters, and vital organ function in THS rats were observed, and the relationship to oxidative stress and mitochondrial fusion-fission was investigated. Results Cal significantly improved hemodynamics, elevated blood pressure, increased vital organ blood perfusion and local oxygen supply, and markedly improved the survival outcomes of THS rats. Furthermore, Cal significantly improved vascular reactivity after THS, including the pressor response of THS rats to norepinephrine (NE), and also the contractile response of superior mesenteric arteries, mesenteric arterioles, and isolated VSMCs to NE. Cal also restored the THS-induced decrease in myosin light chain (MLC) phosphorylation, which is the principal mechanism responsible for VSMC contraction and vascular reactivity. Inhibition of MLC phosphorylation antagonized the Cal-induced restoration of vascular reactivity following THS. Cal decreased oxidative stress indexes and increased antioxidant enzyme levels in THS rats, and also reduced reactive oxygen species levels in hypoxic VSMCs. In addition, THS induced expression of mitochondrial fission proteins Drp1 and Fis1, and decreased expression of mitochondrial fusion protein Mfn1 in vascular tissues. Cal reduced expression of Drp1 and Fis1, but did not affect Mfn1 expression. In hypoxic VSMCs, Cal inhibited hypoxia-induced mitochondrial fragmentation and preserved mitochondrial morphology. Conclusions Calhex-231 exhibits outstanding potential for effective therapy of traumatic hemorrhagic shock, due to its ability to improve hemodynamics, increase vital organ blood perfusion, and markedly prolong animal survival. These beneficial effects result from its protection of vascular function via inhibition of oxidative stress and mitochondrial fission.
Emerging run-time reconfigurable FPGA and CAD tools

Field-programmable gate array (FPGA) is a post fabrication reconfigurable device to accelerate domain specific computing systems. It offers offer high operation speed and low power consumption. However, the design flexibility and performance of FPGAs are severely constrained by the costly on-chip memories, e.g. static random access memory (SRAM) and FLASH memory. The objective of my dissertation is to explore the opportunity and enable the use of the emerging resistance random access memory (ReRAM) in FPGA design. The emerging ReRAM technology features high storage density, low access power consumption, and CMOS compatibility, making it a promising candidate for FPGA implementation. In particular, ReRAM has advantages of the fast access and nonvolatility, enabling the on-chip storage and access of configuration data. In this dissertation, I first propose a novel three-dimensional stacking scheme, namely, high-density interleaved memory (HIM). The structure improves the density of ReRAM meanwhile effectively reducing the signal interference induced by sneak paths in crossbar arrays. To further enhance the access speed and design reliability, a fast sensing circuit is also presented which includes a new sense amplifier scheme and reference cell configuration. The proposed ReRAM FPGA leverages a similar architecture as conventional SRAM based FPGAs but utilizes ReRAM technology in all component designs. First, HIM is used to implement look-up table (LUT) and block random access memories (BRAMs) for func- tionality process. Second, a 2R1T, two ReRAM cells and one transistor, nonvolatile switch design is applied to construct connection blocks (CBs) and switch blocks (SBs) for signal transition. Furthermore, unified BRAM (uBRAM) based on the current BRAM architecture iv is introduced, offering both configuration and temporary data storage. The uBRAMs provides extremely high density effectively and enlarges the FPGA capacity, potentially saving multiple contexts of configuration. The fast configuration scheme from uBRAM to logic and routing components also makes fast run-time partial reconfiguration (PR) much easier, improving the flexibility and performance of the entire FPGA system. Finally, modern place and route tools are designed for homogeneous fabric of FPGA. The PR feature, however, requires the support of heterogeneous logic modules in order to differentiate PR modules from static ones and therefore maintain the signal integration. The existing approaches still reply on designers’ manual effort, which significantly prolongs design time and lowers design efficiency. In this dissertation, I integrate PR support into VPR – an academic place and route tool by introducing a B*-tree modular placer (BMP) and PR-aware router. As such, users are able to explore new architectures or map PR applications to a variety of FPGAs. More importantly, this enhanced feature can also support fast design automation, e.g. mapping IP core, loading pre-synthesizing logic modules, etc.
Coupling plasmas and 3D passive structures in the JET tokamak

The impact of the 3D effects on the dynamic response of the plasma in the JET tokamak is assessed on the time scale of interest for plasma magnetic control and stabiliza tion. These effects are due to the limbs of the magnetic circuit and to the eddy currents in the 3D metallic structures. The plasma behaviour is taken into account by a specific matrix of modifi ed inductances interacting with the remaining part of the syst em via a virtual coupling surface.
The Use and Appropriation of the Mobile Telephony Technologies by the Rural Bangladeshi Farmers

This paper is based on the initial understandings gained from the first half of my doctoral research, that investigates how the mobile telephony technologies can be used and appropriated by the rural Bangladeshi farmers and what could be the potential impacts of such interaction. The research tries to find a relation between the issues raised by the ICT for development literatures and the theoretical underpinnings gained from information systems and marketing. This paper has been developed after the completion of the four month long doctoral fieldwork. An action research approach was undertaken through an intervention by providing the farmers’ groups with mobile telephones. The fieldwork project also provides a model for community based use of the mobile ICTs which can connect the rural farmers among themselves and with the local community based technology centres that have internet connectivity. The farmers’ perceptions about the mobile telephony technology before and after the intervention were collected through interviews and focus group discussions. Ethnographic tool in the form of diary notes describing researcher’s personal observations about the culture and social structure was used to complement the interviews and discussions. The paper provides a snapshot of the theoretical underpinning for the research and a description of the fieldwork. The paper also discusses how the data will be interpreted and analyzed.
