Deep imitation reinforcement learning for self‐driving by vision
Authors: Zou Qijie , Xiong Kang , Fang Qiang , Jiang Bohan
Published: April 2021

Deep reinforcement learning has achieved some remarkable results in self‐driving. There is quite a lot of work to do in the area of autonomous driving with high real‐time requirements because of the inefficiency of reinforcement learning in exploring large continuous motion spaces. A deep imitation reinforcement learning (DIRL) framework is presented to learn control policies of self‐driving vehicles, which is based on a deep deterministic policy gradient algorithm (DDPG) by vision. The DIRL framework comprises two components, the perception module and the control module, using imitation learning (IL) and DDPG, respectively. The perception module employs the IL network as an encoder which processes an image into a low‐dimensional feature vector. This vector is then delivered to the control module which outputs control commands. Meanwhile, the actor network of the DDPG is initialized with the trained IL network to improve exploration efficiency. In addition, a reward function for reinforcement learning is defined to improve the stability of self‐driving vehicles, especially on curves. DIRL is verified by the open racing car simulator (TORCS), and the results show that the correct control strategy is learned successfully and has less training time.
Torque ripple suppression strategy of asynchronous motor for electric vehicle based on random pulse position space vector pulse width modulation with uniform probability density
Authors: Xie Fang , Wu Wenming , Hong Wenjie , Qiu Chenming
Published: April 2021

A random modulation strategy is proposed to suppress the torque ripple of asynchronous motor for electric vehicle in this article. First, the models of harmonic torque and torque ripple are established. The reason of harmonic generation and its effect on torque are analysed. Second, the random position pulse width modulation (PWM) strategy with different random quantities is introduced. The problem of the increasing harmonic content near the integer multiple of the switching frequency in the modulation process is solved. Subsequently, the influences of different random quantity distributions and random number ranges on harmonic suppression are studied. The different structures of random pulse position space vector PWM strategy based on uniform probability density are designed. The specific harmonic content is dispersed and the torque ripple is suppressed. Finally, the precise test platform based on cSPACE is established. The influence of different random PWMs on motor at various speeds is compared. Experimental results verify the validity of the proposed approach.
A bang‐bang control based water‐loop heat pump load aggregation method for power levelling dispatch
Authors: Si Chaoran , Wang Zhen , Ju Ping , Wu Hao
Published: April 2021

In this article, a bang‐bang control based water‐loop heat pump (WLHP) load aggregation method is proposed to facilitate its attending demand response service for the purpose of power levelling dispatch. A WLHP aggregation model is first established to determine its power limit, in which a priority list based on the state of temperature (SOT) index for each heat pump unit (HPU) is developed to measure the HPU's power regulation capability. Users' comfort is also well guaranteed by introducing a forced switching rule in the model. The proposed model is then applied for a power levelling dispatch problem with WLHP load and a bi‐section based bang‐bang control algorithm is developed to determine HPUs' ON/OFF states. A microgrid test system including wind and solar generation, WLHP load and a battery storage is used to validate the effectiveness of the proposed method. To further test its robustness, an influence analysis of initial operating conditions such as input power profiles and initial ON/OFF states as well as multiple operating‐condition simulations are both conducted.

Authors: Li Ying-Xuan , Zhang Yun-Qi
Published: April 2021

With the continuous increase of world’s population, rapid development of industrialization and urbanization, and rapid growth of economy, the fossil fuel consumption is also increasing continuously to meet growing energy demand. The unsustainability of fossil fuels and the issues of national energy security make it very urgent to develop the appropriate and sustainable replacement for fossil fuels. Biodiesel is one of appropriate alternatives for diesel engine due to its renewable and eco-friendly nature. This greener fuel has been used in many countries across the continents in a blending range up to 20% with petrodiesel. However, the high biodiesel production cost is still a major obstacle to market acceptance. Non-edible woody oils can be considered as low-cost substitutions for traditional edible vegetable oils for biodiesel production. In order to make biodiesel into reality in much wider scope, a growing number of relevant researches focused on: (1) evaluating the biodiesel properties; (2) optimizing the production process; and (3) assessing the environmental impact. This article reviews these three aspects in order to reflect the research status and development potential of non-edible woody oil-based biodiesel.

Authors: Chu Chenjing , Shao Mengying , Wang Xiao
Published: April 2021

As one of the frequently detected antibiotics in aqueous environment, the environmental behaviour of tetracycline has received increasing attention. Dissolved biochar (DBC) is an essential component of dissolved organic matter (DOM) in water enviroment. However, the effect of DBC on the photodegradation of tetracycline was unclear. This study investigated the impact of DBC on the photodegradation of tetracycline in aqueous solution under light illumination. The main components of DBC were humic acid-like and fulvic acid-like, accounting for 78.2% of the total components. The DBC surface had more oxygen-containing functional groups and aromatic functional groups. DBC increased the photodegradation of tetracyline by 46.9%, which was related to the component and structure of DBC. These findings would provid theoretical support for the environmental behaviour of DBC and tetracycline in aqueous environment.

Authors: Kunjie Zhang
Published: April 2021

Based on inter-provincial panel data from 2010 to 2018, the author conducted quantitative analysis on the decoupling of economic growth and industrial wastewater discharge as well as its driving factors in the Yangtze River Delta. The research shows during the study period, a high level of decoupling between economic growth and industrial wastewater discharge could be seen in the Yangtze River Delta, mainly in the form of strong decoupling, while at the same time, undesirable conditions such as growth linkages and expansive negative decoupling, still existed in a few years and certain regions. Among the studied regions, Anhui Province, Zhejiang Province and Jiangsu Province all share a similar decoupling pattern with a rather stable overall performance. Shanghai, however, performed poorly among the Yangtze River Delta, with undesirable decoupling states detected in a few years. In terms of driving factors, technology is the core factor that drives the decoupling of economic development to industrial wastewater discharge of the region. The structural effect, on the other hand, is another element worth paying attention to as the technology in the region gradually becomes saturated.

Authors: Fan Dongxuan
Published: April 2021

This paper selects panel data from 30 provinces in mainland China from 2003 to 2017, and empirically explores the role and impact of transportation infrastructure on regional tourism economic development. The results found that the national tourism economy was significantly negatively related to railway density and positively related to highway density, but not significant; the number of employees in travel agencies had little effect on the tourism economy; the urbanization rate, industrial structure, and per capita GDP were significantly positively related to the tourism economy. In terms of different regions, the tourism economy in the western region has a significant negative correlation with railway density and a significant positive correlation with highway density. The regression results of the core explanatory variables in the eastern and central regions are not significant. To promote the development of tourism economy, attention should be paid to the multi-factor synergy that affects regional tourism economic growths; transportation development planning should be integrated with regional macro development planning and the overall tourism development planning; promote urbanization development, upgrade the industrial structure to stimulate the level of tourism consumption and give play to its space spillover effect to promote regional cooperation.

Authors: Weimar Christian
Published: April 2021

Auch wenn die zerebrale Venen-/Sinusthrombose (CVST) eine seltene zerebrovaskuläre Erkrankung darstellt, wird sie zunehmend häufiger diagnostiziert aufgrund erhöhter klinischer Aufmerksamkeit, besserer Bildgebungsmöglichkeiten sowie einer höheren Überlebensrate von Patienten mit prädisponierenden Erkrankungen. Dieser Beitrag zeigt, wie die Diagnose effektiv gestellt werden kann und welche Therapieoptionen in der Akutphase und Sekundärprophylaxe bestehen.

Ziel der Studie Bestimmung der Wirksamkeit eines motivational-volitionalen Programms zur Bewegungsförderung (MoVo-BnB) zu Beginn der medizinischen Rehabilitation für Frauen nach Brustkrebs, die weniger als 60 min Sport treiben.

Methodik Es handelt sich um eine nicht randomisierte, prospektive, bi-zentrische und kontrollierte Studie in 2 Rehabilitationseinrichtungen (Messzeitpunkte: zu Beginn, am Ende sowie 6 und 12 Monate nach Abschluss der Rehabilitation). Die Kontrollgruppe (KG; n=266) erhielt die normale medizinische Rehabilitation und die Interventionsgruppe (IG; n=279) zusätzlich MoVo-BnB (4 von physiotherapeutischem und gesundheitspädagogischem Fachpersonal geleitete Gruppentermine). Die Erhebung der Daten erfolgte als standardisierte schriftliche oder online Befragung. Primäres Zielkriterium ist der zeitliche Umfang der sportlichen Aktivität (BSA-F). Sekundäre Zielkriterien sind gesundheitsbezogene Lebensqualität (QLQ-C30), brustkrebsspezifische Lebensqualität (QLQ-BR23) und Schulungszufriedenheit (HeiQ-Programm). Die Analyse der Interventionseffekte ist durch den Intergruppenvergleich zu den Follow-Up Messzeitpunkten mittels Kovarianzanalyse (ANCOVA) unter Kontrolle der Ausgangswerte erfolgt.

Ergebnisse Nach 12 Monaten sind die Frauen der IG 22 Minuten pro Woche länger sportlich aktiv als die Frauen der KG (95% CI: 2,6 to 41,5; p=0,02). Im Vergleich zur KG betreiben in der IG mehr Frauen mindestens 60 Minuten Sportaktivitäten pro Woche (49,1 vs. 37,6%; p≤0,01). Keine Unterschiede bestehen in der Lebensqualität. Die Bewertung der Intervention seitens der Teilnehmerinnen fällt positiv aus und unterscheidet sich nicht substanziell zwischen den Einrichtungen (p=0,3).

Schlussfolgerung Unsere Ergebnisse zeigen, dass ein auf dem Motivations-Volitionsmodell basierendes kognitives Verhaltensprogramm bei Brustkrebspatientinnen, die gar nicht oder nur minimal sportlich aktiv waren, zu einer langfristigen Verbesserung führen kann. Nach der Diagnose Brustkrebs sollten die Betroffenen noch besser hinsichtlich sportlicher Aktivität unterstützt werden. Praktiker, die in der Krebsnachsorge arbeiten, könnten möglicherweise ein motivational-volitionales Programm zur Verbesserung und Aufrechterhaltung des sportlichen Verhaltens für sedentäre Zielgruppen nutzen.

Ziele der Studie Eine Krebserkrankung im Kindesalter geht häufig mit körperlichen sowie psychosozialen Belastungen einher, die über die Behandlung hinaus bestehen können. Die familienorientierte Rehabilitation (FOR) adressiert Behandlungsfolgen und unterstützt Familien bei der Rückkehr in den Alltag. Ziele dieser Studie waren es, Reha-Ziele und Zielerreichung in der FOR abzubilden, den Zusammenhang von körperlicher Leistungsfähigkeit und körperlichem Wohlbefinden zu analysieren und Prädiktoren der Veränderung der körperlichen Leistungsfähigkeit im Verlauf der FOR zu untersuchen.

Methodik Im Rahmen einer prospektiven Beobachtungsstudie wurden ärztliche Angaben zu Reha-Zielen, Zielerreichung und körperlicher Leistungsfähigkeit bei 175 Kindern (<18 Jahre bei Diagnosestellung einer Leukämie oder eines Tumors des zentralen Nervensystems) zu Beginn und am Ende der FOR analysiert. Das körperliche Wohlbefinden der Kinder wurde aus Eltern- und Patientensicht eingeschätzt. Der Zusammenhang von körperlicher Leistungsfähigkeit und körperlichem Wohlbefinden wurde mithilfe von Korrelationskoeffizienten analysiert. Mittels einer multiplen Regressionsanalyse wurden Prädiktoren der Veränderung der körperlichen Leistungsfähigkeit untersucht.

Ergebnisse Die am häufigsten definierten Reha-Ziele sind die Steigerung der körperlichen Leistungsfähigkeit sowie die Integration in die Gleichaltrigengruppe. Insgesamt werden die Ziele bei 82 bis 100% der Kinder erreicht und die körperliche Leistungsfähigkeit erhöht sich signifikant im Verlauf der FOR. Ein signifikant positiver Zusammenhang besteht zwischen der ärztlichen Einschätzung der körperlichen Leistungsfähigkeit und der elterlichen Einschätzung des körperlichen Wohlbefindens zu Beginn der FOR. Ein weibliches Geschlecht des Patientenkindes sowie eine längere Zeit seit der Diagnosestellung sind mit einer geringeren Veränderung der körperlichen Leistungsfähigkeit assoziiert und ein höheres Ausmaß der körperlichen Folgeschäden geht mit einer größeren Veränderung einher.

Schlussfolgerung Das 4-wöchige multimodale Programm der FOR adressiert verschiedene körperliche und psychosoziale Einschränkungen und geht unter anderem einher mit einer deutlichen Verbesserung der körperlichen Leistungsfähigkeit der Kinder. Die Veränderung der körperlichen Leistungsfähigkeit hängt mit verschiedenen soziodemografischen und medizinischen Faktoren zusammen (u.a. Geschlecht). Die Betrachtung dieser Einflussfaktoren könnte zu einer Optimierung der FOR beitragen.
Venous Thromboembolism in Trauma: The Role of Anticoagulation and Inferior Vena Cava Filters
Authors: Xiao Nicholas , Desai Kush R.
Published: April 2021

Venous thromboembolism (VTE) is a significant contributor to morbidity and mortality among patients with severe trauma. Historically, prophylactic inferior vena cava filters (IVCFs) were used in high-risk trauma patients with suspected risk factors for VTE, including prolonged immobilization, and concurrent contraindication to anticoagulation. Mounting data regarding the efficacy of IVCF in this cohort, as well as concerns regarding morbidity of an in situ IVCF, have challenged this practice paradigm. In this review, we discuss the comanagement of VTE and trauma, including anticoagulation and the use of IVCF.
