Regional Innovation Measured by Patent Data—Does Quality Matter?

This paper devises a new way of measuring the geographical scope of innovation based on patent data and compares its geographical distribution with that of patents granted and production. Indicators of patent quality are used to form an index of regional innovation, which is argued to be an improvement over patent counts, which are seen as indicators of inventions. Innovations are more concentrated than inventions, which in turn are more concentrated than production, gauged by employment levels. Innovations are, moreover, concentrated to regions with already high production and invention levels. This indicates that the concentration of innovation is understated, as raw patent counts are used to proxy for innovation rather than quality patents. The results further point to the need for revaluing effect of R&D on local innovative activity.
Coplanar strip fed UWB antenna with a step cut

A novel compact coplanar strip fed dipole antenna with a step cut suitable for ultrawideband (UWB) application is developed. The antenna is evolved from an open ended slot line by symmetrically etching out two rectangular metallic parts from its upper inner corners. The antenna has −10 dB reflection coefficient from 3.1 to more than 12 GHz that covers the Federal Communication Commission (FCC) specified UWB frequency range. From the simulation and experimental studies, it is found that the proposed antenna delivers moderate gain and stable radiation patterns over the operating band. Time domain analysis on the proposed antenna has been conducted and was found that the antenna can be used for UWB applications. The proposed antenna occupies a compact size of 28.5 × 10 × 1.6 mm3. © 2014 Wiley Periodicals, Inc. Int J RF and Microwave CAE 24:665–672, 2014.
Off-Design Performance Analysis of a Hybrid System Based on an Existing Molten Fuel Cell Stack

This paper addresses the off-design analysis of a hybrid system (HS) based on the coupling of an existing Ansaldo Fuel Cells (formerly Ansaldo Ricerche) molten carbonate fuel cell (MCFC) stack (100 kW) and a micro gas turbine. The MCFC stack model at fixed design conditions has previously been presented by the authors. The present work refers to an off-design stack model, taking into account the influence of the reactor layout, current density, air and fuel utilization factor, CO 2 recycle loop, cell operating temperature, etc. Finally, the design and off-design model of the whole hybrid system is presented. Efficiency at part load condition is presented and discussed, taking into account all the constraints for the stack and the micro gas turbine, with particular emphasis on CO 2 recycle control.
Real‐time photoplethysmographic heart rate measurement using deep neural network filters

Photoplethysmography (PPG) is a noninvasive technique that can be used to conveniently measure heart rate (HR) and thus obtain relevant health‐related information. However, developing an automated PPG system is difficult, because its waveforms are susceptible to motion artifacts and between‐patient variation, making its interpretation difficult. We use deep neural network (DNN) filters to mimic the cognitive ability of a human expert who can distinguish the features of PPG altered by noise from various sources. Systolic (S), onset (O), and first derivative peaks (W) are recognized by three different DNN filters. In addition, the boundaries of uninformative regions caused by artifacts are identified by two different filters. The algorithm reliably derives the HR and presents recognition scores for the S, O, and W peaks and artifacts with only a 0.7‐s delay. In the evaluation using data from 11 patients obtained from PhysioNet, the algorithm yields 8643 (86.12%) reliable HR measurements from a total of 10 036 heartbeats, including some with uninformative data resulting from arrhythmias and artifacts.
PCA Feature Selection For Recognition of Chatter Gestation

A SVM(Support Vector Machine)-like framework provides a novel way to learn linear principal component analysis (PCA), which is easy to be solved and can obtain the unique global solution. SVM is good at classification and PCA features is introduced into SVM. So, a new recognition method based on hybrid PCA and SVM is proposed and used for a series of experiments on chatter gestation. The results of chatter gestation recognition and chatter prediction experiments are presented and show that the method proposed is effective.

Demonstration of first 9.2 kV 4H-SiC bipolar junction transistor

The first demonstration is reported of a high-voltage (9.2 kV) 4H-SiC bipolar junction transistor (BJT) based on a 50 µm, 7×1014 cm−3 doped drift layer, achieving an emitter current density of 150 A/cm2 at VCEO=5 V, suggesting a specific on-resistance (RSP_ON) of 33 mΩ cm2 without considering current spreading or 49 mΩ cm2 if current spreading is considered. The result far exceeds the previous 4H-SiC BJT record of 3.2 kV with RSP_ON=78 mΩ cm2.
Vidéo quantification appliquée a la topographie de la plage intertidale

La mise en place d'une gestion durable et pérenne de la problématique d'érosion nécessite d'appréhender toutes les échelles spatio-temporelles d'évolution morpho-sédimentaire. Depuis quelques années, l'utilisation de systèmes vidéo numériques pour quantifier ces évolutions constitue une alternative autonome et peu coûteuse [Holman and Stanley, 2007] aux méthodes traditionnelles telles que la topographie. Cet article présente une technique de mesure topographique basée sur la détection vidéo du trait de côte dans un environnement méso-tidal. Le principe de la vidéo quantification appliquée au suivi des environnements côtiers est basé sur une technique de photogrammétrie qui permet de transformer une " image oblique brute " en une " image métrique plan " [Trucco, 1998]. Une fois les images sélectionnées, une région d'intérêt est définie manuellement. Les pixels contenus à l'intérieur de cette zone vont être traités à partir d'un algorithme de détection de contour, basé sur une technique de segmentation [Morichon et al., 2007], qui va permettre de séparer les pixels en deux groupes distincts : un groupe concernant les pixels " secs " de la partie sableuse et un groupe concernant les pixels " humides " de la partie océanique. Il est ensuite possible de détecter de façon précise la position du trait de côte. Les coordonnées 2D du trait de côte sur l'image initiale vont ensuite être transformées en coordonnées 3D du monde réel. Cet article présente l'application de cette technique dans un environnement méso-tidal, la grande plage de Biarritz. La détection horaire de la position du trait de côte au cours d'un demi cycle de marée permet alors de mesurer la topographie de la zone intertidale. Cette mesure est ensuite comparée à un relevé topographique réalisé au DGPS centimétrique. La précision de la méthode, ses limitations et les perspectives de développement sont alors discutées.
A heat transfer model of a PV panel integrated with a "Rainscreen Cladding System"

The numerical model presented in the paper was formulated to describe heat transfer in a PV panel integrated with an opaque ventilated facade “Rainscreen Cladding System”. It was assumed that the external layer is not airtight and is adjacent to the air gap behind the PV panels. This means that air flows from both sides of the panel, but inside and outside the air speed and temperature are different. Dynamic, numerical methods are usually dedicated to describe the heat transfer in the whole building domain, including multilayer external wall construction. The results of specific panel temperature and incident solar radiation determine the electricity generated by the PV cell. As an example of the heat transfer analysis the numerical simulations were performed to examine the effect of air flow in a cavity on the temperature of the PV panel. The geometry and dimensions of the wall system were assumed as a constant. The optimum air flow speed was determined by the magnitude of the cracks between panels. Hourly values of weather parameters such as air temperature, solar radiation and wind speed were used to determine heat and mass flow as well as the temperature of the panel during the whole year. The results can be applied to determine the efficiency of solar radiation converted into electricity including changeable weather conditions and the temperature of the PV cell.
The six-minute stepper test is related to muscle strength but cannot substitute for the one repetition maximum to prescribe strength training in patients with COPD

Purpose There are many barriers to pulmonary rehabilitation, including a limited access to evaluation centers. To cope with these difficulties, field tests are often used to prescribe endurance training. As field tests are related to muscle strength, they could also be used to prescribe strength training and increase the access to pulmonary rehabilitation in rural area. However, their validity for this purpose has never been studied. Patients and methods The relationship between the 6-minute stepper test (6MST), 6-minute walk test, maximal workload achieved during cardiopulmonary exercise testing (Wpeak), and one repetition maximum (1RM) was assessed in 35 patients with COPD through a retrospective chart review to derive predictive equation of the 1RM from these tests. The effectiveness of these equations to prescribe strength training at 70% of the 1RM was assessed in an independent cross-validation group of 34 patients with COPD. Results There was a moderate relationship between the 6MST, Wpeak and the 1RM (r=0.44 and r=0.41, respectively, both P≤0.01). Whatever the test, the prescription of strength training using the estimated 1RM compared with the measured 1RM resulted in a mean absolute difference and a mean bias of about 30 kg. Conclusion The use of the 6MST and Wpeak for the prescription of strength training would result in a clinically not acceptable error. Therefore, they should not be used as a substitute for the 1RM to prescribe strength training.
Identification of Partial Discharges in Gas-insulated Switchgear by Ultra-high-frequency Technique and Classification by Adopting Multi-class Support Vector Machines

Abstract Ultra-high-frequency signals are generated due to particle movement, floating conductors, corona, and surface discharges in gas-insulated switchgear. The ultra-high-frequency signal generated due to particle movement is independent of operating pressure and applied voltage. The bandwidth of the ultra-high-frequency signal formed due to corona and surface discharges vary with applied voltage. In a ternary plot, each type of discharge has a unique location. If a variety of discharge occurs simultaneously, it is difficult to classify the type of discharges through the ternary plot. It is demonstrated that the type of discharge can be classified efficiently by adopting a multi-class support vector machine.
Implementing Project-Based Learning And E-Portfolio Assessment In an Undergraduate Course

Abstract In this case study, the aim was to implement project-based learning by utilizing e-portfolio assessment in a small-scale classroom (N = 8). The compulsory Design, Development, and Evaluation of Educational Software course in the curriculum of the Department of Computer Education and Instructional Technology was selected due to its strong relationship with real life while lending itself to addressing the major concern of project-based learning. Despite insufficient classroom size and students’ challenges on animation software, it was found that project-based learning was an appropriate choice for conducting such a course. Moreover, e-portfolio assessment proved to be valuable in project-based learning. In the rest of the paper, findings from other research studies evaluating project-based learning are discussed and recommendations are presented.
Improved quasi-static spectral domain analysis of microstrip lines on high-conductivity insulator-se

An improved quasi-static integral spectral domain analysis (SDA) for multistrips on a layered insulator-semiconductor substrate is proposed. This method of analysis significantly improves previous quasi-static SDA, accounting for the series resistance of the line in addition to the shunt conductance considered in the conventional quasi-TEM SDA. An excellent agreement with the full-wave analysis results is obtained with considerably less computation time.

The Money spent on football is on a large scale . In spite of this, scientific studies interested in the statistical, economical dimensions and performance evaluation for football are scarce in our country and even around the world. One of the reasons for this is because there is no recording of football statistics in our country. FIFA statistics can be held as a sample in this area. FIFA, holds about fifty different football statistics on the player basis or team level during the World Cup matches. It is obvious there is no debating that the performance of the players one by one and as an entire team is very important. The aim of this study is to pioneer for how the performance analysis is applied and how we can benefit from the results obtained in football, if the statistics existed. So, displaying the numerical size of defectiveness mathematically helps the trainers and players. On the other hand, the practical adaptation of data envelopment analysis such as the output oriented Charness, Cooper, Rhodes (CCR) and super efficiency Andersen-Petersen (AP) models are tested for a football performance evaluation.

A Novel Distributed Compressive Wideband Spectrum Sensing Method in Cognitive Radio Networks

In this paper, we present an optimum weighted approach for wideband spectrum sensing. Distributed compressive sensing technology is exploited to obtain dramatic rate reductions while differential procedure is deduced to extremely enhance the detection sensitivity. The measurements are collected from each SU at a fusion center, where a C-out-of-J method is proposed to dramatically heighten the detection performance. SCSMP recovery algorithm is utilized to reconstruct the signals, which are then weighted by the estimated SNRs. Corroborating simulation results show that the raised algorithm can effectively reduce sampling rates at each SU, substantially raise the detection performance and saliently improve system robustness against noise.
Control and measurement of ultrafast pulses for pump/probe-based metrology

In this thesis the control of ultrafast (10−13 s) optical pulses used for metrological applications has been investigated. Two different measurement set-ups have been considered, both based around the ‘pump-probe’ technique, where an optical pulse is divided into two parts, one to ‘pump’ or excite a physical system of interest, the other to ‘probe’ or measure the outcome. In both cases the measurement uses electro-optic sampling (EOS), where an electric field is measured by detecting changes in the optical probe pulse polarisation after interaction with the field. In the first study, a method for wavelength metrology in the terahertz (THz) region has been demonstrated by producing an optical pulse shaper and genetic algorithm to control pump pulses and so indirectly influence the THz spectra they generate. In the second study an OPO (optical parametric oscillator) has been developed to provide ultrafast optical pulses for the generation of < 100 fs electrical pulses for metrology using quantum interference control (QUIC). QUIC electrical signals have been demonstrated successfully by charge accumulation measurements and the QUIC electrical pulse temporally measured using EOS, though the low signal levels due to power restrictions mean the QUIC electrical pulse is unsuitable for metrology at this time. Finally, a portable optical pulse measurement device based around frequency-resolved optical gating (FROG) has been designed, built and tested. This has been shown to be capable of retrieving amplitude and phase information in both the temporal and spectral domains for optical pulses as short as 20 fs duration. The ability to characterise shaped pulses also has been demonstrated successfully, with the requirements for full automation identified.
Clinical characteristics and outcome of fistulizing Crohn's disease: One single‐center experience in Taiwan

Crohn's disease (CD) is characterized by chronic and/or relapsing immune activation and inflammation within the gastrointestinal tract. Approximately 35% of patients with CD are complicated by fistulae. However, little is known about the incidence and natural history of fistulizing CD in Asia, especially enterocutaneous fistulae (ECF). In this study, we aimed to investigate the clinical course and outcomes of patients with fistulizing CD. We performed a retrospective analysis using the database of Chang Gung Memorial Hospital to analysis the clinical characteristics, clinical course of CD, gender, age, medical and surgical treatment, complications, and long‐term outcomes. From January 1989 to November 2016, 97 patients were enrolled (73 males and 24 females) with a median age at diagnosis of CD of 32 years (average 36.28 ± 15.84 years). All of the patients were classified by Montreal classification. Montreal classifications A2 (age 16‐40 years; n = 56, 57.7%), L3 (ileocolonic type; n = 47, 48.5%), and B1 (nonstricturing and nonpenetrating type; n = 43, 44.3%) were the most common phenotypes. ECF occurred in five patients (5.1%), enterovaginal fistula in three patients (3.1%), and enterovesical fistula in two patients (2.0%). The duration of CD before the onset of ECF was 3.9 years, enterovaginal fistula was 2.5 years, and enterovesical fistula was 5 years, and most of the patients complicated with a fistula required surgical treatment.
