1. 21. Automated Gravel Road Condition Assessment : A Case Study of Assessing Loose Gravel using Audio Data

   Författare :Nausheen Saeed; Moudud Alam; Roger G. Nyberg; Diala Jomaa; Mirka Kans; Högskolan Dalarna; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Gravel roads; road maintenance; convolutional neural network CNN ; SVM; decision trees; ensemble bagged trees; GoogLeNet; ResNet50; ResNet18; sound analysis;

   Sammanfattning : Gravel roads connect sparse populations and provide highways for agriculture and the transport of forest goods. Gravel roads are an economical choice where traffic volume is low. In Sweden, 21% of all public roads are state-owned gravel roads, covering over 20,200 km. LÄS MER

3. 22. Cost-effective Communication and Control Architectures for Active Low Voltage Grids

   Författare :Mikel Armendáriz; Lars Nordström; Sami Repo; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active low voltage distribution grids; CAPEX OPEX; communication control architectures; cost-effectiveness; MPC; multiagent systems; photovoltaics; voltage control.; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : The monitoring and control of low voltage distribution grids has historically been disregarded due to the unidirectional flow of power. However, nowadays the massive integration of distributed energy resources into distribution grids, such as solar photovoltaics, distributed storage, electric vehicles and demand response programs, presents some challenges.

   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Negative effects; Internet-based cognitive behavior therapy; deterioration; non-response; adverse and unwanted events; qualitative content analysis; individual patient data meta-analysis; exploratory factor analysis; Negative Effects Questionnaire; Negativa effekter; Internetbaserad kognitiv beteendeterapi; försämring; oförändrat tillstånd; ogynnsamma eller oönskade händelser; kvalitativ innehållsanalys; individuell patient meta-analys; explorativ faktoranalys; Negative Effects Questionnaire; Psychology; psykologi;

   Sammanfattning : Internet-based cognitive behavior therapy (ICBT) has the potential of providing many patients with an effective form of psychological treatment. However, despite helping to improve mental health and well-being, far from everyone seem to benefit. In some cases, negative effects may also emerge. LÄS MER

5. 24. Addressing equality and diversity in the workplace through recruitment materials : an equality monitoring approach

   Författare :Amanda J. Heath; Jens Agerström; Magnus Carlsson; Ishbel McWha-Hermann; Linnéuniversitetet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; equality monitoring; equality diversity inclusion; job advertisements; organizational attraction; ethnicity; recruitment; diversity management; Psychology; Psykologi;

   Sammanfattning : Equality, diversity and inclusion (EDI) statements have been used as part of diversity management in human resources for some time and research suggests they are generally perceived positively and can increase organizational attraction in underrepresented groups, thus promoting diversity and inclusion. The main aim of this doctoral dissertation is to examine the effects of a particular diversity management practice called equality monitoring (EM) and investigate public perceptions of EM and effects on behaviour such as applications, intentions to pursue a job and organizational attraction.
