3. 2. Exchanging 'Life' for Money? Overtime work culture and professional women's fertility intentions in China

   University essay from Lunds universitet/Graduate School

   Author : Jinxuan Lu; [2023]
   Keywords : Fertility intention; Overtime work; PLS-SEM; Vignette experiment; Theory of Planned Behavior; Social Sciences;

   Abstract : In the context of China’s concerning decline in fertility rates and the widespread normalization of the ‘996’ overtime culture, the connection between overtime work and fertility assumes considerable importance. This research is firmly grounded in the theoretical framework of the Theory of Planned Behavior (Ajzen, 1991), which investigates the complex relationship between overtime work and fertility intentions among working women of reproductive age in urban China.

4. 3. Visual Attention Guided Adaptive Quantization for x265 using Deep Learning

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Mikaela Gärde; [2023]
   Keywords : video encoding; deep learning; visual attention; adaptive quantization; videokodning; djupinlärning; visuellt fokus; adaptiv kvantisering;

   Abstract : The video on demand streaming is raising drastically in popularity, bringing new challenges to the video coding field. There is a need for new video coding techniques that improve performance and reduce the bitrates. READ MORE

5. 4. Design, Modeling, and Testing of a Force Feedback Haptic Device for Simulated Robot Interaction

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Patrik Lindström; [2023]
   Keywords : Force Feedback; Impedance Control; PD-gain; Dynamic Behavior; Closed-chain; Master-Slave; Parallel Manipulator; Kinematics Redundancy; Mass-Spring-Damper; Position Control; Current Control; Modeling; Design; Joints; Delta robot; Differential Equations; External Torques; Kinematics; Forward Kinematics; Inverse Kinematics; Dynamic Matrices; Jacobian; URDF; Haptics; Haptic Device; Solidworks; CAD; Maxon Motors; EtherCAT; Beckhoff;

   Abstract : Haptic feedback is a growing phenomenon that incorporates the sense of touch through tactile sensations such as vibrations, electrical signals, air pressure, and sound waves or through force feedback, which employs torques and/or forces to replicate the pressure and weight of a simulated object. Utilizing haptic technology establishes a communication bridge between the user and the technical component, enhancing the user's understanding of the technical component's surroundings. READ MORE

6. 5. Generating Perturbative Solutions for Slowly Rotating Perfect Fluids Using the Hartle Scheme

   University essay from Umeå universitet/Institutionen för fysik

   Author : Elin Johansson; [2023]
   Keywords : ;

   Abstract : In this thesis, we study slowly rotating relativistic stars by modeling them as perfect fluids. The Hartle formalism is used to perturb a spherically symmetric static solution into slow rotation and the corresponding field equations to second order are presented. READ MORE
