Intelligent Packaging for Perishable Products
The preservation of perishable products to maintain their quality is of paramount importance for food safety and security, and is attracting more attention with the increasing concerns on food quality, healthcare and life. Advances in technology and materialsin recent years have led to the development and implementation of intelligent packaging for perishable products that can monitor or evencontrol their quality in supply chain. In this paper, the techniques used in intelligent packaging (i.e., indicators, sensors, and identification technology) and the major printing methods for fabricating electronics (i.e., inkjet printing, screen printing, and gravure printing) are reviewed with a focus on the packagingof perishable products. Althoughthehigh manufacturing costs pose a big challenge for their commercialization and large-scale deployment, it is expected that the technological progressesin printing electronicswill significantly reduce the manufacturing cost of intelligent packaging to a threshold of acceptance by markets and the broad applications of intelligent packaging can facilitate the traction and monitoring of perishable products for better control of the product quality and improved management of supply chain.

Human Emotion Recognition
Automated emotion recognition (AEE) is important issue in the various field of activities, which uses human emotional reaction as a signal for marketing, technical equipment or human-robot interaction. Paper analyzes vast layer of scientific research and technical papers for sensor use analysis, where various methods implemented or researched. Paper cover few classes of sensors, using contactless methods, contact and skin-penetrating electrodes with for human emotion detection and measurement of their intensity. Result of performed analysis in this paper presented applicable methods for each type of emotions or their intensity and proposed their classification. Provided classification of emotion sensors revealed area of application and expected outcome from each method as well as noticed limitation of them. This paper should be interested for researchers, needed to use of human emotion evaluation and analysis, when there is a need to choose proper method for their purposes or find alternative decision.

Fresh Fruit Supply Chain Optimization
The fresh fruit chain has been recognized as a very important and strategic part of the economic development of many countries. The planning framework for production and distribution is highly complex as a result. Mathematical models have been developed over the decades to deal with this complexity. This review focuses on the recent progress in mathematically based decision making to account for uncertainties in the fresh fruit supply chain

Enzyme Based Biosensors
Enzyme-based biosensors were the earliest biosensors. In 1962, Clark proposed the idea of enzyme electrodes for a glucose sensor. Subsequently, enzyme-based biosensors have been experimenting a massive growth in several applications.

Methods and Techniques for CO2 Capture
With the increase in electricity consumption around the world, electricity demands are increasing every day. During electricity generation using energy technologies based on fossil fuels, the emission of harmful pollutants into the environment (gaseous, liquid, and solid) occurs as the emission of NOx, SOx, dust, CO2, and wastewater (e.g., from flue-gas treatment installations). A great deal of effort in modern low-emission energy technologies was directed at activities leading to decreased gaseous pollutant emissions. The emission of carbon dioxide (CO2), treated as one of the main reasons for global warming when fossil fuel is burned, cannot be avoided. The carbon capture utilization and storage (CCUS) methods and technologies are among the many ways to reduce CO2 emissions.

Flux-Modulated Permanent Magnet Machines
High torque density is a desirable feature of electrical machines used in traction applications, such as electric vehicle (EV)/hybrid electric vehicle (HEV) propulsion, wind turbines, more electric air-crafts, etc. The flux-modulated permanent magnet (FMPM) machine is considered as one of the most promising candidates to achieve high torque density. The incorporated gearing effect is ideal in reducing the rotating speed and amplifying the output torque of the FMPM machines.
