Implementation and Improvement of the Total Productive Maintenance Concept in an Organization
Total Productive Maintenance (TPM) is an infrastructure-managing methodology that leads to improvements in production efficiency, quality, and safety. It includes a set of processes, techniques, and strategies based on forecasting, maintenance, the optimized cooperation of different company departments, and the minimization of costs related to downtime or accidents caused by equipment failure. This article discusses the history, assumptions of the TPM concept, and approach to implementing Total Productive Maintenance in organizations in detail. The right ingredients required for successful TPM implementation and barriers to implementation are also reviewed. The benefits of implementing TPM in organizations are presented and supported with examples of implementations in production and non-production organizations. The article is addressed to representatives of the manufacturing industry. TPM also indicates a high potential for implementation in non-production areas, which may be interesting, for example, for the service, medical, or laboratory industries.

Quality Assessment of Laser Welding Dual Phase Steels
Dual phase steels (DP) are one of the most studied steels in the automotive industry, especially after the 1990s when it was decided to reduce the cars’ weight to reduce volatile organic compounds (VOC) and other emissions. The assessment regarding welding DP steel parts should be able to prevent defects from occurring, using finite element method (FEM) analysis to study the material behavior considering the parameterization used during the welding process. It is also necessary to control the possible occurrence of defects during the process, such as porosities, cracks, lack of penetration, etc., controlling the parameters of the welding fixture and ensuring that the operator follows procedures and standards. A batch sample should be subjected to some tests after production to check if there are any defects, such as dimensional errors or porosities in the bead.

Intelligent Forklift Cargo Precision Transfer System
Labor shortage and increasing labor cost are serious problems in today’s society. With the concept of Industry 5.0, it is imperative to promote industrial transformation and accelerate the automation and intelligent development of equipment in order to reduce the pressure brought by the rapid rise in labor costs, so more and more intelligent equipment is used in factories and storage environments. Nowadays, the status of logistics equipment is increasing, and forklifts, as the main force of logistics handling equipment, have been widely used in many fields, such as factories, ports, and warehouses. However, as the requirements of the operating environment continue to increase, the handling equipment can no longer be operated by human hands, especially in special environments, such as high temperature, and hazardous and explosive environments. Along with the development of driverless technology, forklifts are also slowly approaching advanced technologies, such as intelligent identification, wireless transmission, and autonomous navigation and positioning. Intelligent forklifts can enhance the compound ability of forklifts, improve the overall operation level of forklifts, and gradually add more added value. Therefore, intelligent forklifts are the main development direction of forklifts in the future.

MEMS-Based Micro Sensors for Measuring Tiny Forces Acting
Small insects perform agile locomotion, such as running, jumping, and flying. Recently, many robots, inspired by such insect performance, have been developed and are expected to be smaller and more maneuverable than conventional robots. For the development of insect-inspired robots, understanding the mechanical dynamics of the target insect is important. However, evaluating the dynamics via conventional commercialized force sensors is difficult because the exerted force and insect itself are tiny in strength and size. As the force sensor, micro-force plates for measuring the ground reaction force and micro-force probes for measuring the flying force have mainly been developed. In addition, many such sensors have been fabricated via a microelectromechanical system (MEMS) process, due to the process precision and high sensitivity.

Structural Design and Analysis of Wind Turbine
This thesis presents a comprehensive exploration into the design, modeling, and analysis of a wind turbine, employing a multidisciplinary approach to optimize its performance. The blade geometry was generated using QBlade software, a robust tool for blade design in wind turbine applications. The 3D model was then meticulously crafted using SolidWorks, integrating aerodynamic principles and structural considerations. The heart of this project lies in the utilization of SolidWorks Flow Simulation for a detailed analysis of the aerodynamic characteristics of the designed wind turbine. The simulation facilitated a thorough examination of airflow patterns, turbulence effects, and pressure distributions around the blades, offering valuable insights into the efficiency and energy-capturing potential of the turbine under various wind conditions.

Factors Affecting Gecko Toe Adhesion
In real life, geckos’ dwell on a variety of environmental conditions, such as deserts and tropical forests, consisting of surfaces that are often hot, wet, and experience humid conditions. Considerable studies have worked to understand the mechanics of gecko adhesion, but the majority have been performed under highly controlled laboratory surfaces. Less information is available about how surrounding factors such as wet conditions, humid conditions, and surface roughness impact the adhesive abilities of geckos in their natural habitat. Hence, it is necessary to study how environmental factors impact the natural adhesion capabilities of geckos.

Microfluidic Separation and Detection Technologies
Separation and detection are ubiquitous in our daily life and they are two of the most important steps toward practical biomedical diagnostics and industrial applications. A deep understanding of working principles and examples of separation and detection enables a plethora of applications from blood test and air/water quality monitoring to food safety and biosecurity; none of which are irrelevant to public health. Microfluidics can separate and detect various particles/aerosols as well as cells/viruses in a cost-effective and easy-to-operate manner. There are a number of papers reviewing microfluidic separation and detection, but to the best of our knowledge, the two topics are normally reviewed separately. In fact, these two themes are closely related with each other from the perspectives of public health: understanding separation or sorting technique will lead to the development of new detection methods, thereby providing new paths to guide the separation routes.
