ACETABULAR RECONSTRUCTION WITH BONE IMPACTION GRAFTING AND A CEMENTED CUP FOR OSTEOARTHRITIS AFTER ACETABULAR FRACTURE IS ATTRACTIVE. A 3 TO 18 YEARS FOLLOW-UP STUDY. (2006)

Introduction The results of THA in patients with post-traumatic arthritis are inferior to those in nontraumatic arthritis, both after cemented and noncemented THA. This increased failure rate is caused by the bone stock loss and the abnormal anatomy. We studied the outcome of acetabular bone impaction grafting and a cemented cup in 20 cases at 3 to 18 years follow-up. Materials and Methods Between January 1984 and January 2000 in 20 consecutive patients bone impaction grafting was used for arthritis after previous acetabular fracture, grafting was done in all for bone stock loss. There were 14 men and 6 women. The average age at THA was 53.3 years (range, 35 to 75 years). Defects were classified according to the AAOS acetabular defect classification (3 type I defects, 10 type II defects, 5 type III defects and 2 type V). Metal meshes were used in 6 medial wall and in 3 peripheral wall defects. In 15 cases autograft bone chips were used, in 5 both auto- and allograft was used. Grafts were impacted using impactors and a hammer and a PE cup was cemented. At review in January 2003 no patient was lost. Results Two patients died during follow up after 3 and 4 years respectively, deaths were not related to surgery and data are included. The mean follow up was 9.5 years (range, 3 to 18 years). The pre-operative Harris hip score was 44 (32–61). During follow up a cup revision was performed in two cases; one for a culture proven septic loosening 14.5 years after surgery and the other for aseptic loosening at 15.3 years after surgery. Both revised cups were radiologically loose at revision. At review the 16 surviving hips had an aver. Harris hip score of 93 points (range, 62 to 100 points). Fourteen hips were free of pain, one patient had slight and one had mild pain. Radiologically, none of these 16 cups was loose. However, two of the cups migrated more than 5 mm (e.g. 6 and 8 mm) relative to the initial post-operative X-ray. At review, both patients were symptom free. The Kaplan-Meier survival rate of the cup with endpoint revision for any reason was 100% at ten years and 80% (95% CI, 62–98%) after 15 years; with endpoint cup revision for aseptic loosening the survival was 100% both at 10 and 15 years. Conclusion The acetabular bone impaction grafting technique with a cemented cup is a biologically attractive technique to reconstruct the bone stock loss after posttraumatic arthritis with good long-term survival, even after long follow-up.
Electrically controlled phases of partially polarized light and orientational Kerr effect in liquid crystal ferroelectrics (2017)

We study the electro-optic properties of subwavelength-pitch deformed-helix ferroelectric liquid crystals illuminated with partially polarized light. In an experimental setup based on the Mach-Zehnder interferometer, it is found that the interference pattern crucially depends on the degree of polarization of the incident light. We evaluate the electric field dependence of both the Pancharatnam relative phase and the geometric phase for the general case of nonunitarily evolving mixed polarization states.
Fast RFM Model for Customer Segmentation (2022)

With booming e-commerce and World Wide Web (WWW), a powerful tool in customer relationship management (CRM), called the RFM analysis model, has been used to ensure that major enterprises make more profit. Combined with data mining technologies, the CRM system can automatically predict the future behavior of customers to raise customer retention rate. However, a key issue is that the existing RFM analysis models are not efficient enough. Thus, in this study, a fast algorithm based on a compact list-based data structure is proposed along with several efficient pruning strategies to address this issue. The new algorithm considers recency (R), frequency (F), and monetary/utility (M) as three different thresholds to discover interesting patterns where the R, F, and M thresholds combined are no less than the user-specified minimum values. More significantly, the downward-closure property of frequency and monetary metrics are utilized to discover super-itemsets. Then, an extensive experimental study demonstrated that the algorithm outperforms state-of-the-art algorithms on various datasets. It is also demonstrated that the proposed algorithm performs well when considering the frequency metric alone.
Can bipartite classical information resources be activated? (2012)

Non-additivity is one of the distinctive traits of Quantum Information Theory: the combined use of quantum objects may be more advantageous than the sum of their individual uses. Non-additivity effects have been proven, for example, for quantum channel capacities, entanglement distillation or state estimation. In this work, we consider whether non-additivity effects can be found in Classical Information Theory. We work in the secret-key agreement scenario in which two honest parties, having access to correlated classical data that are also correlated to an eavesdropper, aim at distilling a secret key. Exploiting the analogies between the entanglement and the secret-key agreement scenario, we provide some evidence that the secret-key rate may be a non-additive quantity. In particular, we show that correlations with conjectured bound information become secret-key distillable when combined. Our results constitute a new instance of the subtle relation between the entanglement and secret-key agreement scenario.
Using Uplug and SiteSeeker to construct a cross language search engine for Scandinavian (2007)

This paper presents how we adapted a website search engine for cross language information retrieval, using the Uplug word alignment tool for parallel corpora.We first studied the monolingual search queries posed by the visitors of the website of the Nordic council containing five different languages. In order to compare how well different types of bilingual dictionaries covered the most common queries and terms on the website we tried a collection of ordinary bilingual dictionaries, a small manually constructed trilingual dictionary and an automatically constructed trilingual dictionary, constructed from the news corpus in the website using Uplug. The precision and recall of the automatically constructed Swedish-English dictionary using Uplug were 71 and 93 percent, respectively. We found that precision and recall increase significantly in samples with high word frequency, but we could not confirm that POS-tags improve precision. The collection of ordinary dictionaries, consisting of about 200 000 words, only cover 41 of the top 100 search queries at the website. The automatically built trilingual dictionary combined with the small manually built trilingual dictionary, consisting of about 2 300 words, and cover 36 of the top search queries.
Software Pulsewidth Modulation for μP Control of AC Drives (1986)

The on-line pulsewidth modulation (PWM) of a voltage source inverter for converter-fed ac drives is presented. The modulation is realized by software, thus allowing a direct interface between the microprocessor-based speed control and the on-off commands for the inverter. An efficient modulation technique is achieved by asynchronous switching of the inverter phases; a current control loop provides fast feedback, so that a fast step response of the stator currents can be obtained. All control functions, including field-oriented speed control of an induction motor, are performed by a 16-bit microprocessor. Experimental results obtained with a 22-kW induction motor prove that the proposed scheme provides a very good performance of the drive from standstill up to the field weakening range.

An Improved Adaptive Window Stereo Matching Algorithm (2020)

Abstract In order to solve the problem that the existing adaptive window stereo matching algorithms have insufficient feature extraction in low-texture regions, resulting in low matching accuracy. An adaptive window stereo matching algorithm based on the gradient is proposed. Firstly, the Sobel operator is used to extract the gradient value of each pixel in the image. Then, each pixel is divided into high, medium and low texture regions according to the gradient value. Next, different arm length thresholds are assigned to different region pixels, and matching windows are generated dynamically according to arm length and color threshold. Finally, the pixels closer to the center of the window are given higher weights by generating windows several times. It solves the problem that the stereo matching algorithm can not select a matching window dynamically. Experimental results on Middlebury dataset show that the proposed method improves the matching accuracy by 5.5% compared with the latest adaptive window stereo matching algorithm.
Effectiveness of a Matched Filter to Cope With Harsh Phase and Amplitude Modulated EMI (2020)

This article investigates the effectiveness of a matched filter to cope with continuous wave electromagnetic disturbances that are phase and amplitude modulated from wireless systems, e.g., binary phase shift keying and quadrature amplitude modulation. A wired communication channel between sender and receiver that uses nonreturn-to-zero-level data encoding is disturbed by those nearby wireless systems. A matched filter is used on the wired communication channel to filter out the additional unwanted wireless disturbance. The bit-error rate (BER) is calculated after filtering and decoding the received voltages and is used as a metric to compare different kinds of disturbances and different levels of sampling frequency. The results show that the matched filter is very effective when the carrier frequency of the disturbance is equal to an integer multiple of the bit frequency and when not equal to the sampling frequency. This sampling frequency is determined by the bit rate of the desired signal and the oversampling factor on which the matched filter is based. Finally, the filter gain at a BER of 0.1% is determined. This gain shows that an oversampling of 4 times per bit and using a matched filter already results in an average filter gain of 10-15 dB.
Photoconductivity in Discotic Liquid Crystals: A New Class of High-Mobility Materials (1994)

Abstract Using a time-of-flight technique, different transport mechanisms, deep trapping, multiple shallow trapping and Gaussian transport, can be observed in the different temperature and phase regions of the liquidcrystalline (LC) photoconductor hexapentyloxytriphenylene (HPT). Transient photocurrents and carrier mobilities for various temperatures, electric fields, and sample histories were examined. The ideal intrinsic Gaussian transport, observed for holes in the mesophase, puts HPT into a new class of highmobility materials with both hole mobilities on the order of 1.10−3cm2/Vs and a steplike current decay. These features result from the fact that there is obviously neither a positional disorder nor an energetic disorder, which would impair efficient charge transport. This is probably achieved by special molecular packing mechanisms in combination with the dynamical processes of the LC phase and due to favourable properties of the HPT molecule, which has a rigid and conjugated core, a symmetric structure, and no permanent dipole moment.

Wave power absorption: Experiments in open sea and simulation (2007)

A full scale prototype of a wave power plant based on a direct drive linear generator driven by a point absorber has been installed at the west coast of Sweden. In this paper, experimentally collected data of energy absorption for different electrical loads are used to verify a model of the wave power plant including the interactions of wave, buoy, generator, and external load circuit. The wave-buoy interaction is modeled with linear potential wave theory. The generator is modeled as a nonlinear mechanical damping function that is dependent on piston velocity and electric load. The results show good agreement between experiments and simulations. Potential wave theory is well suited for the modeling of a point absorber in normal operation and for the design of future converters. Moreover, the simulations are fast, which opens up for simulations of wave farms.
On the Particle-Contaminated GIS/GITL Systems with Dielectric Coated Electrodes (2001)

Conducting particles in transmission and switching equipment insulated by compressed sulphur hexafluoride (SF6) can re- sult in loss of as much as 90% of the gas dielectric strength. Particles in practical systems can exist in a wide variety of shapes and sizes, and of materials of different densities. In this letter, the effect of particle size on the probability of SF6 breakdown is discussed. Theoretical and ex- perimental results are presented.

Adaptive Through-Wall Indication of Human Target with Different Motions (2013)

Through-wall indication of human targets is highly desired in many applications. Generally, human targets behind wall are noncooperative, and rare prior knowledge about the circumstance behind wall could be available. Thus, it requires the ability to indicate human targets with different motions from clutters. To investigate this problem, we first examine the conventional time-domain indication methods, and find that their performances are controlled by the historical pulse number adopted to estimate background, which corresponds to the tap-length from the angle of filter. Then, based on an intermittent mode of human target echoes, we define the optimum tap-length as the shortest tap-length that makes the filter output signal-to-clutter-and-noise ratio reach maximum and develop an adaptive indication method with a gradient tap-length control scheme to search the optimum tap-length. Finally, through-wall experiments with an impulse through-wall radar demonstrate that the proposed method can obtain a good adaptive indication performance on human target with different motions.

Plant Oil-Based Supramolecular Polymer Networks and Composites for Debonding-on-Demand Adhesives (2019)

The stimuli responsiveness of supramolecular polymers has recently been exploited for the development of adhesives that can be (de)bonded on demand when heated or exposed to UV light. However, it remains difficult to combine competitive solid-state mechanical properties and very low melt viscosity in one material. Here we report a new supramolecular polymer adhesives platform based on soybean oil as a multifunctional low-molecular-weight monomer (∼1500 g/mol) and isophthalic acid (IPA) groups that show hydrogen bonding and promote the formation of a reversible network. The polarity difference between the triglyceride backbone and the IPA groups leads to microphase separation, and the crystalline IPA domains act as physical cross-links. Heating the polymer above the melting temperature of the IPA-rich domains results in a dramatic viscosity reduction to 8 Pa·s at 120 °C. Once cooled to room temperature, the material properties are fully recovered as a result of the reassembly of the supramolecular network. Single lap joint adhesive tests performed at room temperature using glass and stainless steel substrates reveal shear strength values of 1.2 and 1.7 MPa, respectively, and heat and UV light can be used as external stimuli to debond on command. In addition, composites were prepared by adding 5 or 10 wt % microcrystalline cellulose (MCC) to the polymer, and this led to an increase of strength and modulus below the glass transition by up to 80% and 170%, respectively. Because the introduction of MCC partially hinders the crystallization of the matrix, the stiffness and tensile strength are reduced above the glass transition, while the elongation at break is significantly increased.
A parallel hierarchical radiosity algorithm for complex scenes (1997)

The radiosity method is known for generating high quality images of diffuse environments. However it suffers from extensive computation and requires a large amount of memory, especially when the given scene is rather complex. As parallel computing becomes widely available, it is natural to exploit parallelism to speed up radiosity computations. The paper presents a general parallel radiosity algorithm for complex scenes based on a hierarchical method. To achieve the generality, the algorithm is primarily designed for a parallel model machine with distributed memory so that it can be realized easily on any set of homogeneous or heterogeneous machines with message passing capability. To cope with the huge volume of input data and to solve the task allocation problem in parallel computation, the complex scene is first subdivided into cells by axial occluders such as walls, floors and ceilings, and then every cell is augmented to form its cell-visible set according to cell visibility. Then the radiosity of these cell-visible sets are scheduled for parallel processing. In order to facilitate the parallel construction of visible sets, the notion of visible buffer is introduced. Moreover, by exploiting the principle of spatial coherence, a scheduling scheme for visible sets is incorporated so that both the communication and disk access overhead can be reduced. Finally the authors implement their algorithm on the PVM (Parallel Virtual Machine) programming environment over 8 DEC Alpha 3000 machines to investigate its performance. The experiment results show that the parallel algorithm achieves good speedup.
Real-time content-aware video retargeting for tunnel vision assistance (2013)

Image and video retargeting technologies are effective means of resizing media for aspect ratio constrained applications. In this paper, a real-time video retargeting model is proposed for smartphone implementation and potential application to low vision assistance for individuals with tunnel vision. Seam carving is a content-aware retargeting operator which defines 8-connected horizontal or vertical paths, or seams of pixels. The optimality of these seams is based on a specific energy function. Seam removal permits changes in the aspect ratio while simultaneously preserving important regions. This paper introduces a video retargeting model that incorporates spatial and temporal considerations to preserve visual integrity. Face detection masks and salience maps are used to achieve more comprehensive results. Additionally, formulation of a novel temporal coherence measure is presented that allows for retargeting on streaming video in real-time. Integration of the model with a mobile platform emphasizes its portability.

Cloning <i>Aspergillus fumigatus</i> Allergens by the pJuFo Filamentous Phage Display System (1996)

A cDNA library from Aspergillus fumigatus has been displayed on the surface of filamentous phage M13 and screened for gene products binding to human serum IgE. The physical linkage of cDNA gene products to the genetic information required for their production, achieved by exploiting the high-affinity interaction of the Jun and Fos leucine zippers, allows rapid and easier screening of large libraries in semifluid systems. The pJuFo cloning vector is designed to display proteins on the surface of phage and allows selective isolation of genes by gene product-ligand interaction. Thus the system is applicable to clone cDNA that encodes proteins for which a ligand is available. Herein we show that phage expressing IgE binding proteins from A. fumigatus can be enriched and separated from nonspecific phage by using serum IgE from A. fumigatus-allergic individuals coated to plastic dishes. Subsequently, the proteins can be produced in high amounts in Escherichia coli and purified for usage in allergy testing.
