Linking roadway crashes and tire–pavement friction: a case study

Tire–pavement friction is a factor that can affect the rate of vehicle crashes. Several studies have suggested that reduced friction during wet weather conditions, due to water on the pavement surface reducing the contact area between the tire and the pavement, increases vehicle crashes. This study evaluates the effect of friction on both wet- and dry-condition crashes. The data for the study were provided by the New Jersey Department of Transportation. Regression analysis was performed to verify the effect of friction on the rate of wet- and dry-condition vehicle crashes for various types of urban roads. It was found that friction is not only associated with the rate of wet-condition vehicle crashes, but it also impacts the rate of dry-condition vehicle crashes. The analysis also suggested that the developed regression models could be used to define the friction demand for different road categories.
Effect of Deficit Irrigation on Yield, Quality, and Costs of the Production of Native Spearmint

AbstractWater-saving strategies aimed at improving water use efficiency need to be applied in agriculture today to ensure sustainable use of scarce water resources. This article presents results of a 2-year study done at Washington State University’s Irrigated Agriculture Research and Extension Center (IAREC) to determine the effect of various water stress levels applied at various times during the growth period to the yield quantity, quality, and production costs of drip-irrigated native spearmint (Mentha spicata L.). The field experiment included four irrigation levels (40, 54, 80, and 100% of ETc) and four stress timings: T1(the irrigation levels were applied throughout the growing season), T2, T3, and T4 where the irrigation levels were applied 21, 14, and 7 days before harvest, respectively. Hay yields decreased with increasing water stress; mean annual hay yield ranged from 47.2 Mg/ha under the driest treatment (40% irrigation level at timing T1) to 61.2 Mg/ha under 100% irrigation level. Mean ann.
Challenges in Modeling the Unsteady Aerodynamics of Wind Turbines

Many of the aerodynamic phenomena contributing to the observed effects on wind turbines are now known, but the details of the flow are still poorly understood and are challenging to predict accurately, issues discussed herein include the modeling of the induced velocity field produced by the vortical wake behind the turbine, the various unsteady aerodynamic issues associated with the blade sections, and the intricacies of dynamic stall. Fundamental limits exist in the capabilities of all models, and misunderstandings or ambiguities can also arise in how these models should be properly applied. A challenge for analysts is to use complementary experimental measurements and modeling techniques to better understand the aerodynamic problems found on wind turbines, and to develop more rigorous models with wider ranges of application.Copyright © 2002 by J.

Amoebiasis amongst the Orang Asli (aborigine) School Children at Kuala Kubu Bharu, Selangor, Malaysia

Introduction: Entamoeba histolytica is the protozoan parasite of human intestine which is responsible for amoebiasis. Amoebiasis still prevails in our country especially amongst the Orang Asli (aboriginal) communities. Objectives: This study was conducted to investigate the prevalence of amoebiasis amongst the Orang Asli (aboriginal) school children at a primary school in Kuala Kubu Bharu (SKTAR), Selangor, Malaysia. Materials & methods: Cross-sectional study was carried out among 92 volunteered aboriginal school children aged between 7 to 12 years old comprising 49 boys and 43 girls. The stool specimens were collected and screened for E. histolytica by the direct fecal smear method followed by formalin ether concentration technique. Results: The overall prevalence of amoebiasis in this population is 51.1%. The highest infection rate was observed in lower primary school children aged between 7 < 10 years (55.3%). Males (57.1%) have a higher rate of infection compared to females (44.2%). The formalin-ether concentration technique had shown a higher percentage of detection (85.1%) for E. histolytica compared to direct fecal smear (59.6%). Conclusion: E. histolytica infection amongst the aboriginal children at SKTAR still indicates a relatively low health standard of this indigenous community. Improving socioeconomic status, including enhanced access to quality health care and adequate sanitation has the potential to significantly reduce the prevalence and intensity of amoebiasis in this aboriginal community.
Real-time and robust visual tracking

Visual tracking has been extensively studied because of its importance in practical applications such as visual surveillance, human computer interaction, traffic monitoring, to name a few. Despite extensive research in this topic with demonstrated success, it is still a very challenging task to build a robust and efficient tracking system to deal with various appearance changes caused by pose variation, illumination changes, shape deformation and abrupt motion. In this thesis, we address these challenging factors by building several robust appearance models for visual tracking. To effectively select informative features to build an appearance model, we first present an online boosting feature selection approach via optimizing the Fisher information criterion. Recently, the multiple instance learning (MIL) method has been introduced into tracking to solve the sample ambiguity problems. The MIL tracker puts the positive and negative samples into bags, and then selects features with an online boosting method via maximizing the bag likelihood function. However, the features selected by the MIL tracker are less informative to tell target from background. To solve this problem, motivated by the active learning method, we propose an active feature selection approach which is able to select more informative features than MIL tracker by using the Fisher information criterion to measure the uncertainty of classification model, thereby resulting in more robust and efficient real-time object tracking performance. We further show that it is unnecessary to use bag likelihood loss functions for feature selection as proposed in the MIL tracker. Instead, we can directly select features on the instance level by using a supervised learning method which is more
A comparison between two current-fed push-pull DC-DC converters-analysis, design and experimentation

This paper compares two current-fed push-pull DC-DC power converters: the current-fed push-pull power converter or isolated boost and an alternative topology named here as the dual inductor push-pull power converter (DIC). Since this latter converter has just one primary winding, the voltage across the main switches is reduced to the half of that in the isolated boost topology; the average current in the input inductors is also halved and the RMS current in the output capacitor is smaller. The overall efficiency is increased and the power converter's volume is reduced in the DIC converter. These and other improved design characteristics make this alternative topology more attractive than the isolated boost for equivalent applications. Analytical equations, output characteristic curves and computer simulations of both power converters are compared. An experimental breadboard of 480 W power has been assembled in order to verify the performance of the DIC power converter. The main results are provided.
Dialectical Behavioral Therapy from the Lifespan Perspective

This overview outlines dialectical behavioral therapy and its research findings from a lifespan perspective. Dialectical behavioral therapy is an evidence-based therapy initially developed for adults with severe pathologies including borderline personlity disorder, self harm, and suicidality. However, it has since become a more comprehensive treatment model across wider populations. For example, standard dialectical behavioral therapy treatment has been successfully adapted for children and adolescents, and been used as a successful prevention programme as well for intervention. Furthermore, recent advances in the use of empirically-supported treatments through a transdiagnostic approach have made dialectical behavioral therapy dissemination and implementation practices more important. Focusing on current research and implementations of dialectical behavioral therapy from a lifespan perspective and use of dialectical behavioral therapy for interventional or preventional purposes will contribute to the interested researchers and practitioners on its implications across developmental stages.
Bit-Interleaved Coded Modulation with Iterative Decoding in Impulsive Noise

Power line communications (PLC) suffers performance degradation due mainly to impulsive noise interference generated by electrical appliances. This paper considers the application of bit-interleaved coded modulation with iterative decoding (BICM-ID) in the Class-A impulsive noise environment to improve the spectral efficiency and error performance of PLC. In particular, the soft-input soft-output demodulator is developed for an additive Class-A noise (AWAN) channel so that iterative demodulation and decoding can be performed at the receiver. The effect of signal mapping on the error performance of BICM-ID systems in impulsive noise is also thoroughly investigated, both with computer simulations and a tight error bound on the asymptotic performance
The Maturation of Hip-Hop's Menswear Brands: Outfitting the Urban Consumer

Abstract Hip-hop clothing brands emerged in the 1990s in response to a growing acknowledgment amongst its artists that fashion was an important part of the culture. From the 1980s into the 1990s, hip-hop fashion was an adopter of designer brands that represented an aspirational American lifestyle of its wearers. With the introduction of clothing brands in the 1990s, founded primarily by African-American men involved in the rap music industry, hip-hop clothing began to exert its own influence on American fashion. However, as the youth who followed hip-hop culture matured their clothing preferences began to change and few brands were able to quickly adapt. The most successful brands have proven to be those that were the earliest entrants into the market and managed to maintain a brand equity that likely associated them with authenticity among consumers. One of the most profitable brands was headed by hip-hop music entrepreneur Russell Simmons who was also interviewed for this article.
Factors associated with nurses' perceptions and self-confidence in relation to family presence during resuscitation: a cross-sectional study in Indonesia

Background: The presence of family during resuscitation attempts provides moral and religious support for the patient. It also strengthens the relationship between the family and the health care team, as well as the patients. However, the implementation of this practice remains unclear. Purpose: This study aimed to explore the nurses’ perception and their self-confidence in relation to family presence during resuscitation in Indonesia, in order to adapt the Indonesian version of the Family Presence Risk-Benefit Scale and Family Presence Self-Confidence Scale tools. Methods: The study was cross-sectional, using the Indonesian version of the Family Presence Risk-Benefit Scale and Family Presence SelfConfidence Scale tools. Results: 174 nurses working in the intensive care/intensive cardiac care unit and emergency room at a tertiary referral hospital in Riau Province of Indonesia completed the questionnaire, including the opinion-based questions. Our respondents had neither positive nor negative perceptions of family presence during resuscitation (mean score 3.37; SD 1.00). The Pearson r correlation test showed that nurses who perceived more benefits of this practice are more confident when it comes to implementing it (r = 0.618; P-value 0.000). We found that the only demographic factor determining the nurses’ attitudes toward family-witnessed resuscitation was the number of times they had been involved in a resuscitation scenario. Conclusions: A high self-confidence score in implementing family-witnessed resuscitation was found among our respondents. In fact, most of them had invited family members to witness the resuscitation attempt. However, the nurses had a neutral attitude toward family presence during resuscitation. This study also suggests that nurses will likely support this practice when other doctors also support it.
High prevalence of central hypothyroidism among patients with transfusion dependent thalassemia in Hospital Pulau Pinang: A cross sectional study

Results: There were 51 TDT patients, with 24 (47%) males and 27 (53%) females. Most of the patients were Malays (27, 53%) followed with Chinese (23, 45%) and Indonesian (1, 2%). Beta thalassemia major and HbE beta thalassaemia accounted for 35 (68.8%) and 14 (27.5%) TDT patients respectively, while two (3.9%) were HbH Constant Spring. Eleven (21.6%) had hypothyroidism; of which seven (63.6%) had central hypothyroidism, three (27.3%) had subclinical hypothyroidism, the remaining one (9.1%) had primary hypothyroidism. Three (27.3%) had concomitant hypogonadism, one (9.1%) had hypocortisolism and another (9.1%) had both diabetes mellitus and hypogonadism. There was no statistical relationship between the prevalence of hypothyroidism and age, serum ferritin, splenectomy history and iron chelation therapy.

The effect of investment, government expenditure and economic growth on community welfare

Welfare is a reflection of the development success in an area which can be measured with human development index (HDI). In reality, there has never been an equal distribution of the welfare of the people, including in Bali Province, this will not be separated from the influence of investment, government expenditure and economic growth in the area. Realization of investment in each region that is not evenly distributed and the allocation of government expenditure that is not well targeted has resulted in disparities in welfare between districts / cities. This study aims to analyze the effect of investment, government expenditure and economic growth simultaneously and partially on people's welfare. The data used in this study are secondary data from 2014-2019 which were obtained from the Central Bureau of Statistics and the Directorate General of Fiscal Balance. The method of collection was carried out by means of non-participant observation, then the data was processed using multiple linear regression analysis techniques. The test results with SPSS show that investment, government expenditure, and economic growth simultaneously have a significant effect on people's welfare. Government expenditure and economic growth partially have a positive and significant effect on people's welfare. Meanwhile, investment partially has a positive but insignificant effect on people's welfare. Based on the results of the research, it can be suggested that the government can improve regulations related to the ease of licensing and equitable distribution of infrastructure development in each district/city. Optimizing the expenditure function in the fields of human development such as health and education so that the benefits can be felt directly by the community.
Generalisation of a Theorem of Ankeny and Rivlin

International Journal of Instruction

The accessible Flipped classroom is a two-learning phase model that includes preclass and in-class learning phases accessible using standard information technology. The objectives of this study are to explore the effectiveness and investigate the students’ perceptions towards this model to see how the perceptions correlated with the success of the model. This study involved 59 sophomores (98.3% female and 1.7% male) between the ages of 20 to 21 from 2 English presentation classes at Walailak University. A pre-test / post-test were conducted to see the effectiveness, while a survey questionnaire of 22 closed-ended questions and 1 open-ended question was given to them at the end of the term of 12 weeks. The questions were classified into four aspects of perceptions: pre-class learning phase, in-class learning phase, word stress pronunciation, and the overall model. The results confirmed the effectiveness of this model as the average students’ posttest score (M: 8.38) was notably higher than their pre-test score (M: 7.47). Students’ perceptions of each of four aspects were also positively high. However, as bivariate correlations were performed to examine the relationships between the students’ perceptions and post-test results, no significant correlation was found. The study implied that even though the students improved by using the model, they might have needed more time to adapt to a more independent learning culture.
The Rise of Serial Memory and the Future of DDR

With no plans emerging to define a “DDR5” specification, it is certainly clear that the entire memory landscape is going to change profoundly over the coming years. The current DDR4 generation (including the mobile-focused LPDDR4 low-power model) continues to ramp up slowly, but it is essentially the last of its kind, the ultimate generation of memory technology based on the DDR model. LPDDR is being well-accepted in the wireless devices market, but with wireless technology evolving through a generation (or sometimes two) every year, the LPDDR model simply will not be able to keep up. As they become competitively viable, multiple memory technologies are already vying for dominance of this chunk of the memory market space. The current DDR market is expected to be split, and eventually taken over, by new serial memory technologies, like Hybrid Memory Cube (HMC) and other schemes still in the development pipeline. Programmable logic devices like FPGAs and SOCs must maintain support for these new memory schemes as they emerge into the marketplace. This white paper explains why the DDR model is now approaching the end of its useful lifetime, and how serial memory schemes can be expected to fill the memory needs of the future. Xilinx UltraScale devices and platforms have been engineered from the outset with the future in mind, providing a seamless transition to the newly emerging serial memory technologies.
Space vector PWM control of a split-phase induction machine using the vector classification technique

A new and effective space vector PWM control of six-phase voltage source inverters fed split-phase induction motors is presented in this paper. The proposed approach is based on three-phase space vector modulation (SVM) techniques, thereby, it inherently eliminates the 5th, 7th, 17th, 19th, . harmonic currents without extensive computations. Furthermore, the paper utilizes a classification algorithm for the implementation of the SVM which improves the simplicity, accuracy, and the construction execution speed. A comparison is made between the results obtained from the proposed approach, and those from the conventional space vector modulation and the space vector modulation based on a vector decomposition technique. Both feedforward (V/f control), and feedback (vector control) schemes are addressed. Simulation results provided verify the validity of the proposed scheme.

Geographies of Knowledge Sourcing and the Value of Knowledge in Multilocational Firms

A growing body of research in economic geography, international business management and related fields focuses on geographies of knowledge sourcing. This work examines the organizational structure of innovation activities within the firm, the mechanisms by which knowledge is extracted from various external sources and the geography of these different activities. We augment this literature by exploring knowledge sourcing within multilocational firms operating in the US using a unique dataset matching patent records to firm-level ownership and geographical data. The results add value to existing research in three ways. First, the establishments of multilocational corporations are shown to produce different kinds of knowledge in different locations. Second, the patents generated within a firm’s establishments are linked to the knowledge stocks of the cities where they operate, supporting a vision of geographical knowledge sourcing. Third, the complexity of knowledge produced within the firm as a whole is positively related to the number of establishments in which multilocational firms undertake innovation activities. In sum these data suggest that multilocational firms distribute their innovation activities across locations in order to secure access to local pools of tacit knowledge. The complexity value of firms’ knowledge production is enhanced as a result of this spatial strategy. 1 Department of International Business, HEC Montréal 2 Department of Geography, UCLA
