All about validity: an evaluation system for the quality of educational assessment

At all levels of education, tests and assessments are used to gather information about students’ skills and competences. This information can be used for decisions about groups of students or about individual students. When the stakes of these decisions are high, it becomes increasingly important that the assessments used are of good quality. In this dissertation, assessment quality is defined as the degree to which an assessment instrument is appropriate for its intended purpose. This definition entails a flexible view of quality: dependent on the intended interpretation and use of test scores, different quality criteria should be used for evaluation. This approach is also described as an argument-based approach to quality. It originates in validity theory, and our research project aimed to extend it to quality. This is done in a design-based research project whose aim was to develop an evaluation system, which incorporates an argument-based approach to quality, for the quality of educational assessments. In this design-based research project, a theoretical foundation is developed. This theoretical foundation describes the argument-based approach to quality for a single test. It also describes this approach in a context of an assessment program where multiple assessment instances are combined into one decision. From this theoretical foundation, design principles are formulated and then used to build a prototype of the evaluation system. This prototype is then evaluated and adjusted in an iterative process. This dissertation describes the theoretical foundation, the design principles, and several iterations in the development of the prototype.

TPMS Interference Suppression Based on Beamforming

The TPMS(Tire Pressure Monitoring System) is an electronic syst em designed to display the air pressure inside the pneumatic tires and report real-time tire-pressure information to the driver of the vehicle, either via a gange, a pictogram display, or a simple low-pressure warning light. Although the data measured by TPMS sensor is transmitted to internal signal processer in a vehicle through wireless communication, the receiver may suffers from various interferences such as amateur radio station, RFID(Radio-Frequency IDentification) for controlling container, RKE(Remote Keyless Entry) signal, and so on. In this paper, we consider beamforming technology to suppress various high-power interference signals for the TPMS wireless communications. Also, we propose the proper data structure and antenna arrangement for the beamformer inside the vehicle. The performance for the interference suppression is illustrated by computer simulation example.

Also current voltage relationship of the CNTFET with respect to gate oxide thickness and dielectric constant has been analyzed.
Novel FBG rosette for determining impact location in thin plate-like structure

The paper consists of two interdependent parts. The first part presents numerical simulations of output response of single Fibre Bragg Grating (FBG) sensor which is driven by homogeneous deformation along sensor length. The example of such sensor is FBG sensor glued at only two points. The grating length and modulation depth of the refractive index are the critical parameters contributing to performance of the FBG sensors. Numerical analysis allowed to select an appropriate FBG sensors which will be used in the impact detection problem. In the second part of the paper a novel strain rosette with specific sensor array used in impact localisation problem is discussed and presented. The experiment was carried out on thin composite plate with the use of pulse force excitation. The method is based on estimation of principal direction of perturbed travelling wave initiated at impact point and does not use any information about wave propagation velocity.
Keeping up to date: a current review of wearable cardioverter defibrillator use

Abstract The introduction of wearable cardioverter defibrillators (WCD) provides a novel means of protection in select patients at high risk for sudden cardiac death. The WCD can safely record and terminate life-threatening arrhythmias. In this review, we explore the data behind indications for WCD use and discuss its limitations. We searched PubMed, Google Scholar and Cochrane Central Register of controlled trials for relevant studies. The VEST trial, the first randomised controlled trial on WCD use, did not show statistical significance in utility of the WCD in post-myocardial infarction patients with low ejection fraction. While the use of WCD in this select patient population showed no benefit, the findings of the trial merit closer inspection. Various other indications of WCD use still exist and others require exploration. Select subsets of patients who stand to benefit for other indications include severely decreased left ventricular function post-revascularization with high arrhythmic burden, severe non-ischaemic cardiomyopathy, patients awaiting heart transplant and patients who have had their implantable cardioverter device temporarily removed. The role of the WCD is also being explored in children, peripartum cardiomyopathy, haemodialysis patients, and in syncope secondary to high-risk arrhythmias.
Removal efficiency of antibiotics from water through constructed wetlands, a review

Contamination in water bodies with antibiotics and resistance genes is becoming an increasing threat to global health. Overuse of antibiotics has become a serious ecological problem worldwide. There is growing concern that antibiotics are losing their effectiveness due to increased antibiotic resistance in bacteria. During the last twenty years, the consumption of antibiotics has increased rapidly, which has been cited as one of the world’s worst abusers of antibiotics. Several studies have been conducted to solve this issue. Developed countries have introduced several methods but constructed wetlands have been found low cost technology. Although constructed wetlands (CWs) offer a potential way to remove these antibiotics from water supplies, knowledge of their mechanisms is limited. In this review, we highlight important aspects of antibiotic pollution in waters, the removal efficiency of constructed wetlands for antibiotic removal and that antibiotic pollution affects many things which taken together poses several challenges for environmental scientists. It has been discovered that four main factors are affecting the performance of constructed wetlands used for the treatment of antibiotics in water supplies, the types configurations of constructed wetlands, hydraulic load rates, substrates, plants, and microorganisms. Further researches focusing on these factors are recommended to improve the removal efficiency of antibiotics in constructed wetlands. Outcomes of the study could help wastewater treatment plant engineers with providing reliable design data and outline a road map for future researches.
A Dual-Mode SIW Compact Monopulse Comparator for Sum and Difference Multibeam Radar Applications

In this letter, a compact wideband substrate integrated waveguide (SIW) monopulse comparator is proposed. The TE10 and TE20 modes of an SIW transmission line are used to generate in-phase and out-of-phase excitation fields for the sum and difference beams without complex phase shift network. The monopulse comparator can realize maximum 0.4-dB amplitude balance, 3.6° phase balance for both sum and difference ports, and −37.0-dB isolation coefficient within the operating bandwidth of 9.43–10.65 GHz. In addition, to integrate the monopulse comparator with a low-cost beam scanning capability, six monopulse comparators are used as the sources to excite a flat Luneburg lens. The experimental result demonstrates that ±58° beam coverage range with around −20.0-dB null depth and 15.0-dBi gain can be realized. The advantages of the proposed monopulse multibeam antenna, including low profile, low cost, wide beam scanning range, and wide operating bandwidth, make it a very promising solution for low-cost monopulse radar systems.

SWIFT-Tyre: an accurate tyre model for ride and handling studies also at higher frequencies and short road wavelengths

As is well known, Magic Formula tyre modelling (MF-Tyre is a part of ADAMS/Tire) allows an accurate and efficient description of tyre-road interaction forces required for any usual vehicle handling simulation. When it comes to modelling of tyre behaviour at higher frequencies and short road obstacles, which are important for vehicle ride assessment, advanced chassis control systems and chassis system vibrations, a more sophisticated approach is required. In close co-operation with the Delft University of Technology and with involvement of nine automotive companies, TNO has developed the SWIFT (Short Wavelength Intermediate Frequency Tyre) model, which is based upon a rigid ring type of tyre model. The SWIFT model is able to describe dynamic tyre behaviour for in-plane (longitudinal and vertical) and out-of-plane (lateral, camber and steering) motions up to about 60 Hz, and for road obstacles with short wavelength. For reasons of accuracy and calculation speed the SWIFT model has been programmed as a semi-empirical model which is derived using advanced physical models and dedicated high frequency tyre measurements to assess speed effects in tyre behaviour.
User-Level Reliability and Quality Monitoring in Satellite-Based Personal Navigation

High sensitivity receiver technology is necessary to ensure sufficient observation availability of satellite navigation in degraded signal environments. However, high sensitivity processing in the deteriorated line-of-sight conditions is susceptible to bringing about severely erroneous navigation observations. Therefore, when using a satellite navigation system, such as the Global Positioning System (GPS) or the future European Galileo in poor signal conditions, monitoring the reliability and the quality of the obtained user navigation solution is of great importance. This thesis assesses reliability testing and quality control procedures at the user-level in Global Navigation Satellite Systems (GNSS) with the aim of enhancing accuracy and reliability in poor signal conditions with failure detection and exclusion techniques. Reliability testing, namely receiver autonomous integrity monitoring (RAIM) and fault detection and exclusion (FDE), traditionally rely on statistical tests in order to isolate one erroneous measurement from position estimation. In this thesis, a slightly wider point of view is taken to the quality monitoring problem of both user position and velocity, and observation weighting, navigation geometry and accuracy estimation aspects, and statistical reliability theory with applications to personal satellite navigation are assessed. The principal focus of this thesis includes developing and analyzing different FDE schemes based on recursive statistical testing intended for challenging signal environments. The operating environment for the monitoring functions is therefore different from traditional safety-critical navigation, where the usual problem is the failure of only one satellite, and where the error is not necessarily due to obstructions in the propagation path as is the case in urban areas. The results of applying the developed FDE and quality control methods to highsensitivity GPS data from indoor and urban tests and simulated GPS/Galileo data demonstrate that reliability and quality monitoring yield a significant improvement in accuracy and are essential in enhancing the user navigation solution reliability.

Dual Stage Servo Controller for Image Tracking System

In this paper, a dual stage servo mechanism has been developed for image tracking system to improve control performances such as small rise time, small overshoot, small settling time, small stabilization error etc. A secondary stage, a platform, actuated by a pair of electro-magnets is mounted on a conventional elevation gimbal. In this mechanism, the gimbal provides large range but slow motion and the platform provides small range but fast positioning. A sliding mode control is applied to the platform positioning to attain robust performances and stability in the presence of the disturbance related to dynamic coupling of the gimbal and the platform. Results from experiments illustrate that the suggested dual stage mechanism controlled by the sliding mode control is effective in improving responses and attenuating the disturbance response related with dynamic coupling.
Social protest and the middle class in Ghana: a social movement approach of three cases

ABSTRACT This article examines the connection between middle class and social protest by three Ghanaian cases: A protest in the 1890s organised by members of the middle class laid the foundation for political action, which finally led to Ghana’s independence. In 1978, members of the middle class protested a model called Union Government by which the then military head of state Acheampong sought to perpetuate the military into government. In 2014, activists protested frequent power cuts, rising fuel prices and an economic crisis. Following this demonstration, several new middle-class groups evolved, among them ‘Occupy Ghana’. This article looks at the protests and its leadership: How does the activists’ class status relate to forms and practices of protest and resistance? By answering this question, the paper will discuss the specific interests and mobilisations for protest of middle-class activists in Ghana.
Chemical composition and volatility distribution of SOA formed by ozonolysis of β-caryophyllene between 213-313 K

<p>&#946;-Caryophyllene is the most common and abundant of the sesquiterpenes emitted into the atmosphere (Duhl et&#160;al., 2008). Although sesquiterpene emission rates were estimated to be only 9&#8211;16% of the total terpene emissions (Duhl et&#160;al., 2008), they are more reactive and larger in size than monoterpenes. Consequently, their aerosol mass yields are large and result in a significant contribution to the SOA budget in the atmosphere (Tasoglou and Pandis, 2015). Therefore, we studied the composition of both gas and particle phases as well as phase partitioning of SOA from ozonolysis of &#946;-caryophyllene in presence and absence of NOx at five temperatures (213 K, 243 K, 273 K, 298 and 313 K) in the AIDA aerosol simulation chamber. This work focusses on the characterization of the SOA by mass spectrometry employing a FIGAERO-HR-TOF-CIMS operated with iodide ions and a HR-TOF-AMS (both Aerodyne Inc.). Particle phase analysis shows three groups of compound masses with m/z 240-400, (C<sub>5-16</sub>),&#160; (m/z 400-560, (C<sub>20-34</sub>), and m/z 560-680, (C<sub>35-40</sub>) classified as monomers, dimers, and trimers, respectively. &#160; Trimeric compounds were observed preferentially in SOA formed at higher temperatures (273 K, 298 K, 313 K), while only monomeric and dimeric compounds were detected at lower temperatures (243 K and 213 K). Interestingly, dimeric compounds, including C<sub>x</sub>H<sub>y</sub>O<sub>z</sub> and C<sub>x</sub>H<sub>y</sub>O<sub>z</sub>N<sub>1</sub>, contribute more to SOA mass for the lower temperatures. Comparing volatility distributions for the five different temperatures using the Volatility Basis Set (VBS) and thermal desorption information from FIGAERO-CIMS (298-473 K) we find more compounds with lower volatility for lower SOA formation temperatures. This contribution will discuss the volatility distributions obtained with and without NOx as well as the abundance of specific reaction products. </p>

Brain metastasis from colorectal cancer: clinical characteristics, timing, survival and prognostic factors

Abstract Background: Brain metastasis (BM) from colorectal cancer (CRC) seriously affects the survival and quality of life of patients. However, this disease is not fully understood. It is not clear when follow-up monitoring should be conducted to achieve early diagnosis. Furthermore, the reported prognostic factors have varied among different studies. Our study aims to determine the clinicopathological, survival and prognostic factors, as well as the timing of BM occurrence. Methods: We retrospectively studied the patients with BM from CRC between January 2000 and July 2017. The clinicopathologic features were assessed, and the time from primary tumor surgery and extracranial metastases (lung, liver and bone) to the occurrence of BM was calculated, respectively. Survival time after BM was statistically analyzed. Multivariate Cox analysis was carried out to determine the independent factors that affected survival. Results: 52 patients were analyzed. Most of the patients (86.5%) had combined extracranial metastases when BM was diagnosed, and lung was the commonest extracranial metastasis location. The median time interval from CRC surgery to the diagnosis of BM was 20.5 months, and the median time interval from lung, liver and bone metastases to BM was 7, 5 and 2 months, respectively. After diagnosis of BM, the median survival was 9 months. Extracranial metastases (p =.012) and Karnofsky performance status (p =.025) were independent prognostic factors based on multivariate analysis. Conclusion: BM from colorectal cancer often occur in the late stage, and has an extremely poor prognosis. Identifying the timing of brain metastasis can help to detect this disease early.
Apparent limitations of head-up-displays and thermal imaging systems

A simulated helicopter flight through a slalom course was presented on a Silicon Graphics IRIS 3130. The display represented the major visual characteristics of thermal images. Subjects were asked to maintain a designated altitude, while flying a slalom course between regularly spaced pylons. The presence of some of the high frequency details in the image improved subjects' ability to reach and maintain the correct altitude. A head-up-display helped in maintaining altitude, but impaired maneuvering around the poles. The results are interpreted in terms of the competition for visual resources between the HUD and the world view.
Regrouped design in privacy analysis for multinomial microdata

In this paper, we are dealing with the dual goals for protecting privacy and making statistical inferences from the disseminated data using the regrouped design. It is not difficult to protect the privacy of patients by perturbing data. The problem is to perturb the data in such a way that privacy is protected, and also, the released data are useful for research. By applying the regrouped design, the dataset is released with the dummy groups associated with the actual groups via a pre‐specified transition probability matrix. Small stagnation probabilities of regrouped design are recommended to reach a small disclosure risk and a higher power of hypothesis testing. The power of test statistic in the released data increases as the stagnation probabilities depart from 0.5. The disclosure risk can be reduced further if more quasi‐identifiers are relocated. An example of National Health Insurance Research Database is given to illustrate the use of the regrouped design to protect the privacy and make the statistical inference.
