A cross-coupled-structure-based temperature sensor with reduced process variation sensitivity

An innovative, thermally-insensitive phenomenon of cascaded cross-coupled structures is found. And a novel CMOS temperature sensor based on a cross-coupled structure is proposed. This sensor consists of two different ring oscillators. The first ring oscillator generates pulses that have a period, changing linearly with temperature. Instead of using the system clock like in traditional sensors, the second oscillator utilizes a cascaded cross-coupled structure to generate temperature independent pulses to capture the result from the first oscillator. Due to the compensation between the two ring oscillators, errors caused by supply voltage variations and systematic process variations are reduced. The layout design of the sensor is based on the TSMC13G process standard cell library. Only three inverters are modified for proper channel width tuning without any other custom design. This allows for an easy integration of the sensor into cell-based chips. Post-layout simulations results show that an error lower than ±1.1 °C can be achieved in the full temperature range from −40 to 120 °C. As shown by SPICE simulations, the thermal insensitivity of the cross-coupled inverters can be realized for various TSMC technologies: 0.25 μm, 0.18 μm, 0.13 μm, and 65 nm.
ALLOCATION OF POWER QUALITY METERS FOR VOLTAGE SAG ESTIMATION USING EVOLUTIONARY ALGORITHMS

Voltage measurements in specific buses of the power system during events of voltage sags and swells might allow for the estimation of short duration voltage variation (SDVV) in buses where power quality is not monitored. The implementation of SDVV estimation relies on developed methods that make use of a least square error approach by comparing measurement data and simulated results so as to identify the event characteristics, e.g. fault location, fault type and fault impedances. The number of power quality meters and the best way to allocate them along the transmission system is dependent upon the electric network. This paper shows a method for the allocation of power quality meters, evaluating detection and estimation failure rates. In order to determine the best power quality meter allocation for a reliable voltage sag and swell estimation, one could think of an exhaustive search technique. This approach can be applied to small systems (few buses), but is unviable for real transmission systems, since the number of possible combinations of power quality meters is extremely high. Amongst the many optimization techniques applicable to this problem, evolutionary algorithms have proven as a very good alternative. The fitness function was carefully formulated to assess how each possible power quality meter allocation will behave for the estimation and monitoring of voltage sags and swells. The proposed algorithm was implemented and applied to a real transmission network. Some preliminary results are illustrated in this paper.
Voltage control magnetism and ferromagnetic resonance in an Fe19Ni81/PMN-PT heterostructure by strain

Voltage control magnetism has been widely studied due to its potential applications in the next generation of information technology. PMN-PT, as a single crystal ferroelectric substrate, has been widely used in the study of voltage control magnetism because of its excellent piezoelectric properties. However, most of the research based on PMN-PT only studies the influence of a single tensile (or compressive) stress on the magnetic properties due to the asymmetry of strain. In this work, we show the effect of different strains on the magnetic anisotropy of an Fe19Ni81/(011) PMN-PT heterojunction. More importantly, the (011) cut PMN-PT generates non-volatile strain, which provides an advantage when investigating the voltage manipulation of RF/microwave magnetic devices. As a result, a ferromagnetic resonance field tunability of 70 Oe is induced in our sample by the non-volatile strain. Our results provide new possibilities for novel voltage adjustable RF/microwave magnetic devices and spintronic devices.
The Convolutional Visual Network for Identification and Reconstruction of NOvA Events

In 2016 the NOvA experiment released results for the observation of oscillations in the vμ and ve channels as well as ve cross section measurements using neutrinos from Fermilab’s NuMI beam. These and other measurements in progress rely on the accurate identification and reconstruction of the neutrino flavor and energy recorded by our detectors. This presentation describes the first application of convolutional neural network technology for event identification and reconstruction in particle detectors like NOvA. The Convolutional Visual Network (CVN) Algorithm was developed for identification, categorization, and reconstruction of NOvA events. It increased the selection efficiency of the ve appearance signal by 40% and studies show potential impact to the vμ disappearance analysis.
Adaptive best effort protocols for video delivery

This thesis describes the design and implementation of transport level protocols running on top of the IP layer to transmit video data over packet switched networks. These protocols address the issues of meeting real-time deadlines of the video data when transmitted over best-eeort networks like the Internet. The protocols are end-to-end, and do not propose any modiications (like reservations) to the network infrastructure-hence, they can be used over the existing Internet. The design emphasis is on trying to obtain the best quality of video reception possible in the absence of any Quality of Service guarantees from the network. We have considered two kinds of media-Stored Media and Live Media. Stored Media is data stored in a server and transmitted to a client whenever requested (like a video le stored in a video server). Live Media is the live transmission of events; the video server retrieves data from a live source and transmits it to the clients. The performance of the protocol is measured by simulations. iv To my parents v ACKNOWLEDGMENTS

A compact system for two-dimensional readout of Gas Electron Multiplier detectors

There is a growing interest in the use of Gas Electron Multiplier (GEM) and other micro-pattern gas detectors (MPGD) for two-dimensional (2-D) position sensitive measurements of photons or charged particles. A Gas Electron Multiplier Readout Chip (GEMROC) is an Application Specific Integrated Circuit (ASIC) dedicated for 2-D strip readout of GEM detectors. The ASICs deliver the amplitudes and time coordinates of the signals recorded on two sets of orthogonal strips. Timing information is used for finding coincidences of signals on two spatial coordinates while amplitude information is used to find the center of gravity for the cluster of signals belonging to the same detection event. In this paper we present a Field Programmable Gate Array (FPGA) based compact readout system dedicated for these ASICs. The readout system consists of two synchronized FPGA-ADC boards connected to four front-end boards, each one equipped with two GEMROCs. Both FPGAs are connected to a DAQ PC using separate Gigabit Ethernet links. The DAQ PC is equipped with a dedicated C++ based software, which is responsible for configuration of the FPGAs and ASICs settings, storing all the incoming data as well as for on-line/off-line data processing and visualization. The performance of the system is illustrated by test bench measurements.
New developments within the no-core shell model

We review recent developments in the ab initio no-core shell model, such as the influence of 3NFs on the binding energies and excitation spectra of light nuclei. Our calculations permit us to compare the effect of different choices for the theoretical 3NF on the properties of light nuclei. This is of particular interest in determining the best choice of the values for the contact terms in 3NFs derived from Chiral Perturbation Theory. Other recent developments in the NCSM include an investigation of the renormalization properties of physical operators, besides the nuclear Hamiltonian, as well as the Lorentz integral transform approach to the description of select reaction observables in light nuclei.
A Review of hybridization of carbon nanotube into graphene for gas sensor application

Hybridization of two mechanically strong materials which is carbon nanotube and graphene can provide specific advantages over other materials in gas sensor research and can relate to the chemical properties. Consequently, graphene and carbon nanotube show extreme sensitivity towards changes in the local chemical environment that originates from the susceptibility of the electronic structure to interacting molecules. Furthermore, a sensitivity and chemical selectivity to a diverse array has made them perfect candidates for consolidation into the design of gas sensor. The development of hybridization of carbon nanotube and graphene based gas sensor still in its infancy, but attempts to make the gas sensor more quantitative are important for further advancement of gas sensor innovation.
Rapid Daignostic Lateral Flow Strip Test Reader

Non-invasive rapid diagnostic tests (RDT) are commonly used to detect some kind of viruses or bacteria instead of invasive methods. Helicobacter pylori ( H. Pylori ) which causes gastric cancer, peptic ulcer, gastritis, mucosa-associated lymphoid tissue lymphoma diseases can be detected easily with lateral flow strip (LFS) that is one of the RDT types. The tests are evaluated whether there are control line and test line at the region of interest (ROI) by users or microbiology technicians manually. Once the test line is tentative, despite the test must be reported positive, it can be resulted as negative incorrectly. This incorrect diagnose causes incorrect treatment planning. In this work, to mitigate this problem which will be able to occur by human based, an automatic LFS-RDT reading system is developed. The computer laptop based system firstly takes image utilizing the holders that are designed with 3D printer. Whether the test have the control-test lines or not are carried out by image processing techniques straightforwardly. After feature extraction from line areas, k- NN classification method is used to evaluate the test results automatically. 100 LFS-RDTs are tested and observed that all results are correct. The system is found quite useful and approved as a second reader by medical technicians.
A QUANTITATIVE ANALYSIS OF COUPLING FOR A WPT SYSTEM INCLUDING DIELECTRIC/MAGNETIC MATERIALS

Dielectric or magnetic materials introduced in a wireless power transfer (WPT) system affect the properties of WPT. This paper quantitatively studies the coupling between the transmitting and receiving elements for a WPT system including either dielectric or magnetic materials. The transmitting and receiving elements are open spirals and solenoid coils which are usually used in WPT systems. The analysis method is the perturbation method which can calculate the total coupling coefficient k, the electric coupling component ke and the magnetic coupling component km simultaneously. This paper gives quantitatively analyzed data on km and ke to indicate how much km and ke are affected by a dielectric or magnetic material introduced in a WPT system.
Tidally-induced thermonuclear supernovae

We discuss the results of 3D simulations of tidal disruptions of white dwarfs by moderate-mass black holes as they may exist in the cores of globular clusters or dwarf galaxies. Our simulations follow self-consistently the hydrodynamic and nuclear evolution from the initial parabolic orbit over the disruption to the build-up of an accretion disk around the black hole. For strong enough encounters (pericentre distances smaller than about 1/3 of the tidal radius) the tidal compression is reversed by a shock and finally results in a thermonuclear explosion. These explosions are not restricted to progenitor masses close to the Chandrasekhar limit, we find exploding examples throughout the whole white dwarf mass range. There is, however, a restriction on the masses of the involved black holes: black holes more massive than 2×105 M⊙ swallow a typical 0.6 M⊙ white dwarf before their tidal forces can overwhelm the star's self-gravity. Therefore, this mechanism is characteristic for black holes of moderate masses. The material that remains bound to the black hole settles into an accretion disk and produces an X-ray flare close to the Eddington limit of LEdd ≊ 1041erg/s (Mbh/1000 M⊙), typically lasting for a few months. The combination of a peculiar thermonuclear supernova together with an X-ray flare thus whistle-blows the existence of such moderate-mass black holes. The next generation of wide field space-based instruments should be able to detect such events.
Detection system for microimaging with neutrons

A new high-resolution detector setup for neutron imaging has been developed based on infinity-corrected optics with high light collection, combined with customized mounting hardware. The system can easily be installed, handled and fitted to any existing facility, avoiding the necessity of complex optical systems or further improved electronics (CCD). This is the first time optical magnification higher than 1:1 has been used with scintillator-based neutron detectors, as well as the first implementation of infinity corrected optics for neutron imaging, achieving the smallest yet reported effective pixel size of 3.375 μm. A novel transparent crystal scintillator (GGG crystal) has been implemented with neutrons for the first time to overcome limitations of traditional powder scintillators (Li6/ZnS, Gadox). The standardized procedure for resolution measurements with the Modulation Transfer Function (MTF) is summarized to facilitate comparison between instruments and facilities. Using this new detector setup, a resolution of 14.8 μm with a field of view of 6 mm × 6 mm has been achieved while maintaining reasonable count times. These advances open a wide range of new possible research applications and allow the potential for additional future developments.
Application of polymer-gel dosimetry in stereotactic radiosurgery

Stereotactic irradiation with the Leksell gamma knife (Elekta Instrument AB, Stockholm, Sweden) is one of the primary methods used for the stereotactic radiosurgery treatment of intracranial lesions. To assure the quality of the whole treatment procedure a proper dosimetric system is required. The polymer-gel dosimeter evaluated by nuclear magnetic resonance (NMR) is a promising tool to satisfy this requirement. The purpose of this study was to investigate the use of polymer-gel dosimeter as a dosimetric tool for the quality control of stereotactic radiosurgery procedures performed by the Leksell gamma knife.
Limited use only. How can the design of an everyday object help chronic stroke patients to overcome the learned nonuse of the upper limb?

Abstract Stroke causes significant damage to the brain and symptoms commonly affect one or both limbs on one side of the body. Compensatory movement is the preferential use of the non-affected limb and is a common phenomenon after a stroke, leading to a learned nonuse of the affected side. This learned nonuse of an upper limb can be overcome through constraint induced movement therapy (CIMT) during which the non-affected arm is physically restrained to enhance the use of the affected arm. This paper presents the outcomes of a design course with undergraduate students in which the students developed design solutions based on CIMT components that encourage the use of the affected arm. Six design solutions were evaluated by therapists with experience in stroke rehabilitation. Their feedback indicates that the designs have the potential to be used in a self-directed way by stroke survivors and that they contain a therapeutic value.
The HERMES recoil detector

For the final running period of HERA, a recoil detector was installed at the HERMES experiment to improve measurements of hard exclusive processes in charged-lepton nucleon scattering. Here, deeply virtual Compton scattering is of particular interest as this process provides constraints on generalised parton distributions that give access to the total angular momenta of quarks within the nucleon. The HERMES recoil detector was designed to improve the selection of exclusive events by a direct measurement of the four-momentum of the recoiling particle. It consisted of three components: two layers of double-sided silicon strip sensors inside the HERA beam vacuum, a two-barrel scintillating fibre tracker, and a photon detector. All sub-detectors were located inside a solenoidal magnetic field with a field strength of 1T. The recoil detector was installed in late 2005. After the commissioning of all components was finished in September 2006, it operated stably until the end of data taking at HERA end of June 2007. The present paper gives a brief overview of the physics processes of interest and the general detector design. The recoil detector components, their calibration, the momentum reconstruction of charged particles, and the event selection are described in detail. The paper closes with a summary of the performance of the detection system.
Software Benchmarking

In software, "benchmarking" usually compares two companies' practices and results, but, occasionally, it involves sets of companies. For example, there are benchmark comparisons of industry software, such as insurance software, military software, telecommunication software, commercial software, and the like. In other domains, "benchmark" usually means the collection of a substantial body of quantitative data. Benchmark comparisons of various computers, for example, rate their relative performance in at least half a dozen categories. Historically, software benchmarks have been qualitative rather than quantitative. Even the Software Engineering Institute's Capability Maturity Model (SEI CMM) is essentially a qualitative benchmark that ranks company performance on a five-point scale that lacks quantification for specific quality and productivity levels. >
Sustainable Design Futures: An open design vision for the circular economy in fashion and textiles

Abstract This paper explores the concept of the circular economy within the context of fashion and textile design in the UK, and does so from the textile and fashion perspectives to explore how this might be achieved. Within the UK alone, we dispose of approximately 10,000 garments every ten minutes (Kerr & Foster, 2011). This project focuses specifically on the practice of textile and fashion design in the UK to consider a more holistic approach for designing and manufacturing within these sectors. Our research aims are to explore the contribution open design can make in implementing the circular economy and thus a more sustainable material future. We ask what are the new models and systems of production that will support a circular economy in textiles? In this work we propose a vision for circular economic models of production in fashion and textiles that adopt open design approaches.
Visual communication interface for severe physically disabled patients

During the last years several interfaces have been developed to allow communication to those patients suffering serious physical disabilities. In this work, a computer based communication interface is presented. It was designed to allow communication to those patients that cannot use neither their hands nor their voice but they can do it through their eyes. The system monitors the eyes movements by means of a webcam. Then, by means of an Artificial Neural Network, the system allows the identification of specified position on the screen through the identification of the eyes positions. This way the user can control a virtual keyboard on a screen that allows him to write and browse the system and enables him to send e-mails, SMS, activate video/music programs and control environmental devices. A patient was simulated to evaluate the versatility of the system. Its operation was satisfactory and it allowed the evaluation of the system potential. The development of this system requires low cost elements that are easily found in the market.
CURIE: a new clear air doppler radar dedicated to the lower part of the atmospheric boundary layer (20 m- 750m)

A new X-band miniradar, the CURIE radar (Canopy Urban Research on Interactions and Exchanges), mainly adapted to low Atmospheric Boundary Layer sounding has been developed at CETP. After a brief description of the opportunity and working conditions in a turbulent atmosphere, main characteristics are presented. Though this radar works in presence of precipitation as all X-band radar can do, this paper is more dedicated to clear air used in the turbulent atmospheric boundary layer. We are presented comparisons with UHF observations and boundary layer information which can be inferred from CURIE as entrainment across the inversion layer.
Research on stress intensity factor of crack at intersection of crossbores

Circular crossbore as a common geometric construction exists widely in the engineering components. Its fatigue life is heavily decreased by the crack failure around the intersecting line. So, the typical analysis model of crossbores with mode I crack is built, and the influence of four main parameters, such as thickness–diameter ratio Y, crossbores diameter ratio Q, crack length a, and axis ratio of elliptical crack face b/a, on fracture parameter KI is presented. The results show that the distribution of KI is mainly influenced by Q and b/a, and the influence of b/a is more obvious. The value of KI is mainly influenced by Y, Q, and a, while the influence of b/a is not evident. For elliptical crack face, the KImax (maximum value of KI) located at the short axis leads to higher crack growth rate. KImax is a crucial factor of fracture criterion, and the significance of factors on it is also analyzed here. A variance analysis of four factors is performed and their order is Y > Q > a > b/a. In addition, a calculation function of KImax is built based on 294 sets’ data and the error is analyzed by mean absolute percentage error with maximum error being less than 7.2%.
