Design and assessment of a battery-supercapacitor hybrid energy storage system for remote area wind power systems

Recent advances in innovative energy storage devices such as supercapacitors have made battery-supercapacitor hybrid energy storage systems technically attractive. However the field of hybrid energy storage system control is relatively new, involving the major challenge of developing control techniques optimised for improved battery-life or other performance metrics. This thesis presents the design and analysis of an actively controlled hybrid energy storage system. Detailed information is given regarding the system implementation and dynamic controls developed as a part of the research. Novel use of the sliding-mode or hysteretic current-controlled DC/DC converter is shown to provide a versatile and robust power electronic building block for the power-control hardware implementation. Current state of the art in the field has converged around a frequency-domain approach to the overall power sharing strategy within hybrid energy storage systems employing batteries and high-power, low-energy density storage such as supercapacitors, with benefits in terms of reduced battery current maxima and an (un-quantified) increase in battery life having been reported. This research extends previous studies by considering the frequency-domain approach in further detail and providing quantitative simulation results confirming how an estimated increase in battery cycle-life of ~18% can be achieved. A systematic simulation framework used for the development and assessment of novel hybrid energy storage system control strategies is described and demonstrated in the context of a remote wind power application. The hardware design of all systems considered is described in detail and demonstrated by experiment.
Training in Information Management for Army Brigade and Battalion Staff: Methods and Preliminary Findings

Abstract : Training, training Support software, and measurement instruments were developed to help Army brigade and below staff manage information and overcome information overload in a digital messaging environment. Development of the training was guided by two theoretical models: a model of team adaptations to stress and a model of adaptive decision making. The instruction focused on selected skills concerning critical thinking and team coordination. The results of a pilot study suggest that training may have beneficial effects on the targeted skills. Measures of decision accuracy, decision making processes, information filtering, and information production were developed. Methods of automating the training and measures, and approaches to feedback and adaptation of instruction, practice, and testing are described. Concepts for a system architecture are presented.
Searchable Encrypted String for Query Support on Different Encrypted Data Types

Data encryption, particularly application-level data encryption, is a common solution to protect data confidentiality and deal with security threats. Application-level encryption is a process in which data is encrypted before being sent to the database. However, cryptography transforms data and makes the query difficult to execute. Various studies have been carried out to find ways in order to implement a searchable encrypted database. In the current paper, we provide a new encrypting method and querying on encrypted data (ZSDB) for different data types. It is worth mentioning that the proposed method is based on secret sharing. ZSDB provides data confidentiality by dividing sensitive data into two parts and using the additional server as Dictionary Server. In addition, it supports required operations on various types of data, especially LIKE operator functioning on string data type. ZSDB dedicates the largest volume of execution tasks on queries to the server. Therefore, the data owner only needs to encrypt and decrypt data.
Motion Sickness Prevention by Stroboscopic Environment during Simulated Military Transport

Abstract : Previous studies have shown stroboscopic illumination to reduce the severity of motion sickness symptoms when retinal slip is a significant factor. The present study assessed the use of a 4 and an 8 Hz stroboscopic environment as a countermeasure for visually-induced motion sickness. The motion profiles of an Army UH-60 Black Hawk helicopter and a Marine AAVC7A1 Amphibious Assault Vehicle were produced using the U.S. Army Aeromedical Research Laboratory's Multi Axis Ride Simulator. Participants who experienced the UH-60 motion profile subjectively reported the 8 Hz condition as significantly more effective in controlling motion sickness symptoms than the 4 Hz condition. In addition, the same participants reported a greater mean number of motion sickness symptoms (regardless of severity) after the no strobe condition than the 8 Hz condition; however this difference was not significant. Although there was no conclusive evidence of stroboscopic illumination as a motion sickness countermeasure in the objective performance measures, there was evidence of its effectiveness in subjective reports.
Mobile application for obtain information from our geolocation TRAVEL GUIDE

[ANGLES] In today's world, mobile technologies have an important role as they have been gaining ground in an excessive manner, and today it is hard to see someone who does not have mobile. In addition, these technologies have also evolved over the benefits offered by incorporating new features that facilitate daily, such as reading mail, take pictures, watch videos, communicate via chat with other friends, etc. All these advantages have made you think of developing new mobile applications to incorporate these devices, so to provide new and useful services to users who use them. The purpose of this project is to implement a mobile application developed for devices with Android system, we provide real-time information sites / events of interest that are close to the user's location. The application, which allows interaction with Google Maps, you get the user's position and display on screen the same location plan, along with points of interest that are in that location. When the user selects one point who wants to visit, the application will display a menu of options that will allow us to obtain information from these sites and the ability to get recommendations from others who have already visited the site before. The application is designed considering an interface make it user friendly and to include all possible options required, including the ability to make a blog on the distance traveled, store information and directions to the site of interest without the need for WI-FI, among others. As shown the results the average response time of real-time application will depend on the speed of communication between the remote server and application, but in average does not exceed 3 seconds using text as a communication medium for a response quick
Impact of Safe@Home on Placement and Permanency Outcomes: Results of a Quasi-Experimental Study

This study assessed the effectiveness of Safe@Home, an in-home intervention to (1) prevent out-of-home placement for children at imminent risk of placement, and (2) minimize time in out-of-home care for children already in foster care. Using Coarsened Exact Matching, children who received Safe@Home were matched to a comparison group of children served before Safe@Home was available in their community. All children were determined by the child welfare agency to be unsafe and in need of immediate intervention. The matched samples (Safe@Home n = 510, Comparison n = 851) showed strong baseline equivalence on child age, race/ethnicity, previous history of child welfare involvement, and safety threats. Children who received Safe@Home experienced lower rate of out-of-home placements, higher rate of permanency with a parent (sustained for 12 months after the end of Safe@Home), fewer days in out-of-home care, and shorter time to case closure relative to children who received treatment as usual. There was no effect of Safe@Home on post-permanency outcomes of maltreatment and entry or re-entry after case closure.
Optics in data center network architecture

Modern data center networks with their vast scale and bandwidth requirements are necessarily optical networks. Only optical communication technology has demonstrated capacities of 10 Gb/s, 40 Gb/s, and higher, over distances of more than 10 m. However, traditional data center network architectures limit the use of optics to the physical cables only, requiring wasteful electrical-optical-electrical conversions between every pair of switches. This dissertation presents three data center network architectures that use optics in novel ways for scaling the network, while simultaneously reducing CAPEX and OPEX, and managing cabling complexity. The first architecture is a single large electronic packet switch with enough ports and enough capacity to interconnect every host in the data center. This architecture uses a FatTree topology of merchant silicon switch ASICs, and manages the resulting cabling complexity using a combination of horizontal-vertical arrangements of circuit boards, and aggregation to higher bitrates for multiplexing over thin optical fiber cables. The second architecture is a hybrid electrical/optical network, with a smaller portion of the core switches being electrical packet switches and the remaining switches being optical circuit switches. Wavelength division multiplexing reduces the number of optical circuit switches and cables even further. This architecture has a lower CAPEX and OPEX than a traditional data center network, while also having a performance that approaches that of a traditional fully packet switched network. Measurements are presented from a fully working prototype network called Helios. The third architecture is a microsecond-scale optical circuit switch that is fast enough to completely replace electronic packet switches for bulk traffic. A novel circuit scheduling algorithm is presented called traffic matrix scheduling that can support arbitrary communication patterns and executes in polynomial time. Measurements are presented from a fully working prototype switch called Mordia. The combination of these architectures and their promise of less expensive bandwidth scaling will hopefully bring data center operators closer to the goal of treating the entire data center as a single computer.
PEMBUATAN PAPAN PARTIKEL BERBAHAN BAKU SABUT KELAPA DENGAN BAHAN PENGIKAT ALAMI (LEM KOPAL)

The side product of coconut plantation in Indonesia is coconut fiber which along that time only used as products such as doormat, broom, etc. Therefore, it needs to do the study to increase the addition value of it, where coconut fiber as the side product of coconut plantation exported to other countries to be used by them to be particle board or other products. For increasing addition value of coconut fiber, it was done the study of making particle board from raw material of coconut fiber by using copal glue as a binder. This study used a mix between coconut fiber and copal glue in comparison 1:5 and 1:6 with the comparison of compression was 4:1. The testing which was done to know physic and mechanic characters of this particle board were density and static bending test to obtain Modulus of Elasticity (MOE) and Modulus of Rupture (MOR). The density testing shows that particle board with fiber comparison 1:6 has little density, whereas the result of bending test for MOE is 1:5 =64.2672kg/mm2 ; 1:6 = 89.2009 kg/mm2, and the result of bending test MOR is 1:5 = 2.4555 kg/mm2 ; 1:6 = 1.7513 kg/mm2. Keywords: coconut fiber, particle board, MOE, MOR
Numerical modelling of electrodeposition process for printed circuit boards manufacturing

Printed circuit boards (PCBs) are used extensively in electronic products to connect assembled components within a system. The so-called vertical interconnect access (via) is a vertical hole or cavity in the PCB filled with metal to facilitate conductivity. The current trend, particularly for high technology products (e.g., 3D packaging), is to manufacture PCBs with high aspect ratio (AR) vias. Typically, the size of such a via is at the micrometer scale (this is why they are termed micro-vias). The most widely used technique for manufacturing micro-vias is electrodeposition of metal (e.g., copper), where the PCB is immersed into a plating cell filled with an electrolyte solution. Using standard conditions, electrodeposition usually does not produce micro-vias with the required quality. This is due to a lack of copper ion transport into the via. This has lead to studies of various ways of enhancing the ion transport. This thesis documents the results from a modelling study into the electrodeposition processes for fabricating high aspect ratio micro-vias. This includes basic electrodeposition and techniques that enhance ion transport such as forced convection (using a pump) and acoustic streaming (using transducers). In this work, a novel numerical method for explicitly tracking the interface between the deposited metal and the electrolyte is implemented and validated under the conditions of basic electrodeposition using experimental data. Results from a parametric study have established a set of design rules for micro-vias fabrication. When ion transport is enhanced by forced convection (e.g., pumping) in the plating cell, we apply a multi-scale modelling methodology that provides interaction between models at the macro level (the plating cell) and the micro level (the interior of a via). Numerical simulations can then be used to verify how ion transport into the micro-via is improved. These results can then be used to identify process conditions for the plating cell which will result in the required flow behaviour at the micro-via. Megasonic agitation can also be used to enhance electrolyte convection in the plating cell. This is achieved by placing megasonic transducers into the plating cell. This leads to several phenomena, one of which is known as the acoustic streaming. Models have been developed for predicting megasonic agitation both at the macro and micro-scales, and a number of designs have been investigated for both open and blind micro-vias.
Whole-vehicle radiated EMI immunity tests in automotive EMC: establishing and calibrating the test field

In EMI immunity testing, the test fields used to expose the device under test must be calibrated so that the levels of exposure can be controlled and maintained at the values required by the test specification. In testing a whole vehicle this can be particularly difficult; the large, usually metallic, structure of the vehicle can couple to the test antenna or field generator and change its characteristics, thus changing the exposure. The author discusses the difficulties of EMI immunity testing for whole vehicles. Calibration of the incident test field is discussed, including the advantages of precalibration rather than monitoring at the device under test; shielded enclosure effects; and calibration accuracy. Also discussed is incident field correction for field generators and radiators with EM field antennas, H-field generators and E-field generators all being dealt with. >

In blind, controlled field experiments, early Stage II zoeae of Dungeness crab (Cancer magister DANA) were exposed to sounds from single discharges of a 13.8-litre array of seven air guns. Their survival and development were followed during subsequent laboratory culture. Immediate mortality was low (0 to 2%) and showed no significant difference between control and exposed larvae ( alpha > 0.05). Across all treatments and blocks of the experiment, survival to the molt to Stage III averaged 88.8%. The conditional Stage IV survival rate averaged 69.8%. The times to the molts to Stage III and Stage IV averaged 14.4 and 34.9 days, respectively. For immediate and long-term survival and time to molt, the field experiment revealed no statistically significant ( alpha > 0.05) effects on zoeae for exposures as close as 1 m from the array, nor for mean sound pressure as high as 231 dB re 1 mu Pa and cumulative energy density up to 251 J/m sub(2). Post hoc power calculations showed that any reduction in zoeal survival as a result of sound exposure was less than 7% for survival to Stage III and less than 12% for Stage IV conditional survival (1beta = 0.90, alpha = 0.05 one-tailed). The sound exposures in our study were at the maximum levels likely to be experienced by a zoea during an actual survey.
Three‐dimensional visualization of cranial soft tissues in embryonic and early postnatal mice using phosphotungstic acid enhanced microCT

Acquiring three‐dimensional imaging of animal specimens utilized in genetic, developmental, and evolutionary studies has typically been based on microCT (bone and mineralized tissues) and magnetic resonance microscopy (soft and un‐mineralized tissues). However, recent advances in microCT imaging have allowed for 1–5 μm resolution for small biological specimens, while typical microMRI imaging can generally only produce data with a resolution of approximately 30–40 μm. In order to achieve high‐resolution 3D visualization of soft tissues, the use of various contrast agents have been proposed, including iodine, osmium, and phosphotungstic acid (PTA). We investigated protocols for using PTA to stain soft tissues of the head in embryonic and early postnatal mice to enhance visualization of soft tissues by microCT imaging. Protocols for mice between embryonic day 13.5 and postnatal day 7 have been developed that allow for the visualization, segmentation, quantification, and analysis of soft tissue structures. Stained specimens were mounted in a 50:50 mix of polyester and paraffin waxes within a small tube and scanned on the GE v|tome|x L300 scanner in the Center for Quantitative Imaging at Pennsylvania State University with voxel dimensions between 1 and 10 μm, depending on specimen size. Multiple soft tissue structures, including the eye, inner ear, cartilage, muscle, glandular tissue, and brain, are easily differentiated in the resultant scans. Images of PTA‐stained specimens can be superimposed with microCT images of the same specimen before PTA staining to enable the study of relationships between hard and soft tissues in the same individual. This approach to both 2D and 3D visualization of soft tissues in murine models has immediate implications for understanding developmental processes and integration between hard and soft tissues of the cranium.
Use of 3-D virtual environments to support the learning of pro- gramming

Departamento de Engenharias, Universidade de Tras-os-Montes e Alto Douro, Apartado 1013, 5001-801 Vila Real, Portugal The research and development of approaches to help students overcome the difficulties of acquiring good programming skills is a concern common to many institutions and researchers worldwide. One such ap-proach is the use of virtual learning environments that allow students to freely explore several contextual-ized learning activities provided to them. We propose the use of scriptable 3D collaborative virtual envi-ronments in particular, as a way to provide support and context for collaborative programming activities. One of the main problems regarding the use of such virtual environments in a formal educational envi-ronment is that of connection between real-world goals stemming from collaboration, and their execution in virtual environments. The coordination of efforts typically follows methods of communication amongst participants that are supplied by traditional systems, external to the environments where interactions are taking place. Here we analyze this problem and a pathway to its study.
Design and implementation of metamaterial based strain sensor using aperture coupled antenna

Strain sensors are used to convert the physical measured quantity of strain into an electrical signal suitable for processing by electronic equipment. Traditional strain sensors are comprised of a thin flexible film with a resistive pattern traced on the surface. As the sensor is deformed, the electrical resistance changes proportionally, giving a direct measure of the strain incurred. Metamaterials, particularly split ring resonators (SRR), lend themselves as a valuable tool for sensing applications due to their highly resonant nature and their very narrow bandwidth (high Q-factor). Due to very high field localization effects, they are extremely sensitive to both the dielectric properties of the materials they are deposited on and in close proximity to, allowing for a high degree of tunability. The benefit of using metamaterials as a sensor lies in the fact that as a microwave device, they can be used to realize passive wireless sensors as compared to the current technology which requires supporting circuitry to measure and transmit data. This thesis will address the feasibility of implementing a metamaterial based strain sensor that exploits the tunable nature of the SRR as it is calibrated with a traditional resistive strain sensor and then applied to quantify the strain incurred on a loaded cantilever beam. This thesis is approved for recommendation to the Graduate Council
Energy Efficiency of an Electric Vehicle Propulsion Inverter Using Various Semiconductor Technologies

In this Licentiate thesis, various solutions to improve the efficiency in the electrical vehicle drive drive line such as in the propulsion inverter and in the electric machine, are proposed and their benefits are quantified from an energy efficiency point of view. The efficiency analysis is based on modeling of a power electronics inverter, an electric machine and a battery in various drive cycles of an electric vehicle. A solution to improve the efficiency in the electric machine is proposed. A loss minimizing optimized current vector control is suggested for a PMSM which minimizes the total machine losses. The solution has for the investigated electric machine up to 8% efficiency improvement or 1.5% improvement in average efficiency of various drive cycles such as ECE, EUDC and US06. Several solutions are studied for the propulsion inverter. It is shown that by replacing the ordinary silicon pn freewheeling diodes in the propulsion inverter with SiC diodes, an average efficiency improvement of about 0.5 percent can be expected in various drive cycles. Furthermore by replacing the Silicon IGBTs in the inverter with SiC MOSFETs, the drive cycle efficiency in various drive cycles can be increased between 4 to 6 percents. Finally a controllable dc-link voltage for the propulsion inverter is investigated in order to qualify the energy efficiency gain for the inverter and the motor. Their drive cycle energy efficiency improvement is 0.5 to 1 percent when using a SiC based inverter and 4 to 6 percents for an IGBT based inverter.
