Robot-Assisted Endovascular Interventions Technologies and Application
Prior methods of patient care have changed in recent years due to the availability of minimally invasive surgical platforms for endovascular interventions. These platforms have demonstrated the ability to improve patients’ vascular intervention outcomes, and global morbidities and mortalities from vascular disease are decreasing.

Control Strategy for High Speed On/off Valves
Digital hydraulic technology is considered to be a potential solution to replace traditional hydraulic servo control technology in the “Industry 4.0” era. Digital valves mainly consist of incremental digital valves and high speed on/off valves (HSV), of which the former have been abandoned by academia and industry due to its low-frequency and tendency to become out-of-step.

Shale Oil Occurrence Mechanisms
Shale oil resources are important supplements for the gradually decreasing oil production from conventional reservoirs. The exploitation and development of shale oil have achieved considerable progress, the commercial extraction of hydrocarbons from shales is still difficult, especially in the lacustrine sedimentary basins of China.

Information Technologies in Transport Logistics
Efficient business in the field of transport requires knowledge based on logistics, logistics personnel and information technology which form an integrated system, which is called the logistics information system. Today, information systems are the ones who make the company more competitive, modern and efficient, so without their wide application it is impossible to survive on the market, which is very demanding in terms of optimization of logistic activities and processes. This paper presents the implementation of logistics information systems on the example of urban public transport company GSP „Belgrade“, whose main activity is the transport of passengers in urban and suburban traffic.

Extraction and Purification of Volatile Fatty Acids
Volatile fatty acids (VFA) are intermediary degradation products during anaerobic digestion (AD) that are subsequently converted to methanogenic substrates, such as hydrogen (H2), carbon dioxide (CO2), and acetic acid (CH3COOH). VFA recovered from the AAD fermentation can be further converted to sustainable biofuels and bioproducts. This text describes the latest developments in the extraction techniques of VFA from complex organic materials.

Fresh Fruit Bunch Ripeness Evaluation Methods
There are two types of methods to analyse the ripeness of fresh fruit bunches (FFBs), destructive methods and nondestructive methods. The destructive methods require physical contact in ways that affect the integrity of the FFBs and severely reduce the amount of oil that can be extracted from the tested FFBs. Meanwhile, the nondestructive techniques can involve noncontact features that are either visual or nonvisual. Nonvisual methods include using physicochemical, electrical, magnetic, and electromagnetic properties to determine fruit maturity such as fluorescence sensor, microwave sensor, inductive sensor, and thermal sensor. However, most nondestructive methods are visual, in which the selected sensor can evaluate through the morphology, colour, and other physical characteristics of the fruit to identify their maturity stages through the analysis of specific modalities such as colour vision, light detection and ranging, spectral image, and near-infrared spectroscopy.

Challenges in Sewer System Maintenance
A sewer system is an important infrastructure of every settlement. A sewer system is a set of construction facilities used for the quick removal of wastewater from the humans’ immediate environment and its transport to a wastewater treatment plant or direct discharge into an appropriate recipient. In order for the sewer system to perform its purpose properly, its proper maintenance is required. Maintenance of a sewer system is very demanding since the system is mostly underground which makes it difficult to be accessed and maintained. The maintenance of a sewer system can be preventive (regular) or corrective (reactive). The regular maintenance occurs at certain intervals, whereas the reactive maintenance occurs in the case of some unforeseen event. This paper presents the history of sewer systems, as well as basic and alternative types of sewer systems. Furthermore, challenges that arise during sewer system maintenance and difficulties that maintenance employees face in their work are presented in this paper, as well as the ways in which sewer systems are maintained.

Theoretical Framework of Thermoelectric Generation
The world’s growing energy demand poses several concerns regarding the rational and efficient use of energy resources. This is also the case for many industrial processes, where energy losses and particularly thermal losses are common. Thermoelectric generators offer an alternative to address some of these challenges by recovering wasted heat and thereby increasing the overall efficiency of these processes. The successful operation of the thermoelectrical modules meant to carry this process is only possible when pairing these to an external control system; such a system plays an important role in predicting and operating such modules at its maximum power point.

Resource Planning Systems Incorporation into Building Information Modelling
The latest industrial revolution 4 enabled significant performance improvement through technological advancements. Simultaneously, the industry is setting high-level expectations for changing business practices toward long-term benefits in all three sustainability dimensions. The concept of sustainability embraces all production and operation processes in the Architecture, Engineering, and Construction (AEC) industry.

Sustainable Desert Agriculture Systems with Saline Groundwater Irrigation
Agricultural land expansion is a solution to address global food security challenges in the context of climate change. However, the sustainability of expansion in arid countries is difficult because of scarce surface water resources, groundwater salinity, and the health of salt-affected soil. Developing expansion and sustainability plans for agriculture requires systems thinking, considering the complex feedback interactions between saline groundwater, salt-affected soil, plant growth, freshwater mixing with saline groundwater, irrigation systems, and the application of soil amendments to alleviate the salinity impacts.
