Although CA are envisioned as powerful deterministic computers, their intrinsic capabilities are expanded after the memristor’s probabilistic switching is introduced into CA cells, resulting in new hybrid deterministic and probabilistic memristor-based CA (MemCA). In the proposed MemCA hardware realization, memristor devices are incorporated in both the cell and rule modules, composing the very first all-memristor CA hardware, designed with mixed CMOS/Memristor circuits. The proposed implementation accomplishes high operating speed and reduced area requirements, exploiting also memristor as an entropy source in every CA cell. MemCA’s functioning is showcased in deterministic and probabilistic operation, which can be externally modified by the selection of programming voltage amplitude, without changing the design. Also, the proposed MemCA system includes a reconfigurable rule module implementation that allows for spatial and temporal rule inhomogeneity., Peer Reviewed, Postprint (published version)

While magnetic solid-state memory has found commercial applications to date, magnetic logic has rather remained on a conceptual level so far. Here, we discuss open challenges of different spintronic logic approaches, which use magnetic excitations for computation. While different logic gate designs have been proposed and proof of concept experiments have been reported, no nontrivial operational spintronic circuit has been demonstrated due to many open challenges in spintronic circuit and system design. Furthermore, the integration of spintronic circuits in CMOS systems will require the usage of transducers between the electric (CMOS) and magnetic domains. We show that these transducers can limit the performance as well as the energy consumption of hybrid CMOS-spintronic systems. Hence, the optimization of transducer efficiency will be a major step towards competitive spintronic logic system., Computer Engineering

The focal-plane module is the key component of the DEPFET sensor with signal compression (DSSC) mega-pixel X-ray imager and handles the data of 128 ×512 pixels. We report on assembly-related aspects, discuss the experimental investigation of bonding behavior of different adhesives, and present the metrology and electrical test results of the production. The module consists of two silicon (Si) sensors with flip-chip connected CMOS integrated circuits, a Si-heat spreader, a low-temperature co-fired ceramics circuit board, and a molybdenum frame. A low-modulus urethane-film adhesive fills the gaps between on-board components and frame. It is also used between board and heat spreader, reduces the misfit strain, and minimizes the module warpage very efficiently. The heat spreader reduces the on-board temperature gradient by about one order of magnitude. The placement precision of the bare modules to each other and the frame is characterized by a standard deviation below 10 and 65 μ m, respectively. The displacement due to the in-plane rotation and vertical tilting errors remains below 80 and 50 μm, respectively. The deflection of the sensor plane shows a mean value below 30 μm with a standard deviation below 15 μm. Less than 4% of the application-specified integrated circuits (ASICs) exhibit a malfunction. More than two-thirds of the sensors have a maximum leakage current below 1 μA. © 1963-2012 IEEE.

Microstrip antenna has attracted many researchers in the applications of wireless communications due to its high performance in terms of high gain, wideband, unidirectional radiation pattern and low cross polarization. This type of antenna can be used to process a function of multimode/multiband operations, high speed data transmission and long-distance communication. There are many techniques adopted to obtain these specifications on the printed microstrip antenna. In this thesis, high gain wideband grating bowtie microstip antenna has been designed. To achieve a unidirectional radiation pattern antenna, an electrical grating bowtie dipole and magnetic half ring dipole have been designed by using grating bowtie dipole, half ring dipole and a cavity backed. The cavity backed has been utilized here for two functions; first to work as an image to the dipoles so that the grating bowtie dipole with its image acts as an electric dipole and the half ring dipole with its image functions as magnetic dipole, in addition to reduce the back lobes. These dipoles were proposed to obtain an equal amplitude and phase in an electric and magnetic current. According to Huygens’ source theory, if the current sources are excited by the same amplitude and phase, unidirectional and low back radiation patterns can be obtained accordingly. However, the results of the bandwidth and gain were still need to be improve. So that a technology of enhancing the gain and bandwidth are required. In order to earn wider bandwidth, a multistage transformer is employed. Which enhance the bandwidth from 9 % (5.3 GHz to 5.8 GHz) to 52.9 % (5 GHz to 8.6 GHz). Whereas, the gain was from 8.4 dB to 14.3 dB. To improve the radiation pattern, a method of pattern radiation improvement is required.

Finite element (FE) models are often used to study the biomechanical effects of traumatic brain injury (TBI). Measures based on mechanical responses, such as principal strain or invariants of the strain tensor, are used as a metric to predict the risk of injury. However, the reliability of inferences drawn from these models depends on the correspondence between the mechanical measures and injury data, as well as the establishment of accurate thresholds of tissue injury. In the current study, a validated anisotropic FE model of the human head is used to evaluate the hypothesis that strain in the direction of fibers (axonal strain) is a better predictor of TBI than maximum principal strain (MPS), anisotropic equivalent strain (AESM) and cumulative strain damage measure (CSDM). An analysis of head kinematics-based metrics, such as head injury criterion (HIC) and brain injury criterion (BrIC), is also provided. Logistic regression analysis is employed to compare binary injury data (concussion/no concussion) with continuous strain/kinematics data. The threshold corresponding to 50% of injury probability is determined for each parameter. The predictive power (area under the ROC curve, AUC) is calculated from receiver operating characteristic (ROC) curve analysis. The measure with the highest AUC is considered to be the best predictor of mTBI.Logistic regression shows a statistical correlation between all the mechanical predictors and injury data for different regions of the brain. Peaks of axonal strain have the highest AUC and determine a strain threshold of 0.07 for corpus callosum and 0.15 for the brainstem, in agreement with previously experimentally derived injury thresholds for reversible axonal injury. For a data set of mild TBI from the national football league, the strain in the axonal direction is found to be a better injury predictor than MPS, AESM, CSDM, BrIC and HIC., QC 20190619

Heterogeneous multicores are envisioned to be a promising design paradigm to combat today's challenges of power, memory, and reliability walls that are impeding chip design using deep submicron technology. Future multicores are expected to integrate multiple different cores, including GPGPUs, custom accelerators and configurable cores. In this paper, we introduce an important dimension - technology - using which heterogeneity can be introduced in multicores to improve their energy-performance envelope. Specifically, we analyze the benefits of heterogenous technologies for processor cores and cache subsystems. We discuss two promising device candidates (Tunnel-FET and Magnetic-RAM) for introducing technological diversity in the multicores and analyze their integration in the processor and cache hierarchy in detail. Our analysis shows that introducing such a kind of heterogeneity can significantly enhance the performance and energy behavior of future multicore systems. ©

A hybrid spectral domain - UTD method (Uniform Theory of Diffraction) developed for the analysis of conformal antennas is presented in this paper. The basic idea behind the hybrid method is to combine different analysis methods for conformal antennas and, at the same time, preserve the advantages of the considered methods. More specifically, the considered hybrid SD - UTD method joins the possibility of analyzing multilayer structures (spectral domain method) and the possibility of analyzing electrically large structures (UTD method). Hence, using the developed method it is possible to analyze large multilayered conformal antennas with high accuracy and speed. This work has been made possible by the ACE program for structuring the research on conformal antennas in Europe. The developed method is a result of joining research activities of University of Zagreb, Croatia and the Royal Institute of Technology, Sweden., QC 20141125

This paper presents the theory, design procedure, and implementation of a dual-band planar quadrature hybrid with enhanced bandwidth. The topology of the circuit is a three-branch-line (3-BL) quadrature hybrid, which provides much larger flexibility to allocate the desired operating frequencies and necessary bandwidths than other previously published configurations. A performance comparison with other dual-band planar topologies is presented. Finally, a 3-BL quadrature hybrid for dual band (2.4 and 5 GHz) wireless local area network systems was fabricated, aimed to cover the bands corresponding to the standards IEEE802.11a/b. The measurements show a 16% and 18% bandwidth for the lower and upper frequency, respectively, satisfying and exceeding the bandwidth requirements for the above standards., Peer Reviewed

A new `circuit model' for converting between even and odd modes in asymmetric series impedances in the ground plane of a coplanar waveguide is presented. The model is based on the separation of modes into two input and two output ports. In contrast to previous work, it enables a quantitative analysis of the energy exchange between modes to be obtained., Peer Reviewed

Summary: The main objective of the research is to develop computationally efficient hybrid coding schemes for the low bit implementations of image frames and image sequences. The basic fractal block coding can compress a relatively low resolution image efficiently without blocky artifacts, but it does not converge well at the high frequency edges. This research proposes a hybrid multi-resolution scheme which combines the advantages of fractal and DCT coding schemes. The fractal coding is applied to get a lower resolution, quarter size output image and DCT is then used to encode the error residual between original full bandwidth image signal and the fractal decoded image signal. At the decoder side, the full resolution, full size reproduced image is generated by adding decoded error image to the decoded fractal image. Also, the lower resolution, quarter size output image is automatically given by the iteration function scheme without having to spend extra effort. Other advantages of the scheme are that the high resolution layer is generated by error image which covers the bandwidth loss of the lower resolution layer as well as the coding error of the lower resolution layer, and that it does not need a sophisticated classification procedure. A series of computer simulation experiments are conducted and their results are presented to illustrate the merit of the scheme. The hybrid fractal coding method is then extended to process motion sequences as well. A new scheme is proposed for motion vector detection and motion compensation, by judiciously combining the techniques of fractal compression and block matching. The advantage of this scheme is that it improves the performance of the motion compensation, while keeping the overall computational complexity low for each frame. The simulation results on realistic video conference image sequences support the superiority of the proposed method in terms of reproduced picture quality and compression ratio., College of Engineering and Computer Science, Collection: FAU Electronic Theses and Dissertations Collection, Thesis (Ph.D.)--Florida Atlantic University, 1995.

A system was developed to mass produce thick-film hybrid integrated circuits on ceramic substrate. This technology was tested successfully with the production of 3000 XM734 multioption fuze amplifier assemblies. The high-volume, continuous production applies to military environments and incorporates high component density. Nonrecurring costs in capital equipment and minimal labor are among the major economic advantages. (Author)

Running efficiency of LHR diesel has been confirmed by mean of well-known types of heat-insulating (HICs) or thermal barrier (TBCs) coatings. These materials are considered as a semitransparent media SHICs (STBCs) in the form of an ensemble of diffraction objects, forming own thermoradiative fields under the scattering theory laws. This problem is relevant for a diesel with combustion chamber (CC) in which intensive IR radiation reaches ~50% of total thermal flux. The authors indicate that predetermined selection of optical and thermoradiative parameters in the same spectrum for coatings (due to specific structural composition and porosity) can change their temperature fields inside its subsurface zone and hence in the CC gas volume. Previous author's research of optical parameters for ceramic semitransparent materials allowed offering SHIC (STBC) samples for rig testings. Optically simulated absorption and scattering indices for SHICs fix their thermoradiative fields which determine the formation of optimal temperature profile inside ceramic coatings at the type conditions of diesel CC operation. A number of the latest rig testings of diesel engines with coated piston by PSZ-ceramics were studied from the point of influence on the radiant heat exchange by semitransparent coatings deposited on the CC internal surfaces. Analysis and reasons of reducing the specific fuel consumption at high speeds using SHICs (STBCs) were carried out. In view of the known literature data on rig testings of LHR diesel and also experimentally measured optical parameters of semitransparent and opaque coatings it became possible for the first time to calculate correctly its temperature fields. Subsurface heating of semitransparent ceramic coats specifies the possibility of thermoregulation for the piston surface with SHICs (by varying its structure) in contrast to the use of opaque HICs. Such PSZ-ceramics were recommended for application and improvement of operating conditions of diesel C
