Positive Effect

The utilization of wireless technology in traditional medical services provides patients with enhanced mobility. This has a positive effect on the recovery speed of a person after major surgical procedures or prolonged illness. Ultrawideband (UWB) radio signals have inherent characteristics that make them highly suitable for less invasive medical applications. This paper surveys our own and related recent research on UWB technology for medical sensing and communications. Some research perspectives in the aforementioned topics are suggested too.

Acoustic Wave Sensor

Research topics related to the production of nanocomposites are the most important directions of development of new semiconductor engineering, ensuring high nanocomposites obtaining useful properties in the scope of biophysical characteristics, biomedical and piezoelectric applications. We present two case studies as Hydroxyapatite are in medical applications and aluminum nitride as acoustic wave sensor. Hydroxyapatite, is the main inorganic structure of the tooth enamel and bone and is a biomaterial that is commonly used in biomedical applications that involve bone substitution, drug delivery and bone regeneration because of its excellent biocompatibility, high bioactivity and good osseoconductivity. Since the past decade. Aluminum nitride (AlN), an electrical insulating ceramic with a wide band gap of 6.3 eV, is a potentially useful dielectric material very important in fields such as optoelectronic and micro electronics.

Security Issues

Telemedicine is defined as the means of providing healthcare for people from a distance by the use of telecommunication and information technology. This technology is mainly useful in overcoming the obstacles of distance and provide enhancement in the access of medical services that would not be easily available in different rural areas. Telemedicine security includes issues such as confidentiality, integrity, and authentication that are also present in other systems involving information and data. Maintaining integrity of data stored and used is a huge problem for medical applications because it contains more sensitive medical records of patients which can cause severe ill effects on slight modification. In order to resolve the confidentiality and integrity issues of telemedicine applications, medical image encryption and watermarking comes into play. The security issues in telemedicine applications is to be given higher importance and thus choosing a reliable and effective approach or framework is more essential.

The work is devoted to the search for answers to the question: “Are there any differences in the public procurement of customers who provide services of different quality?”. The article identifies the stages of the hospital procurement process in the contract system and highlights the main customer strategies used in the auction. The results of an independent quality assessment are examined and comparative hospital characteristics with low and high quality rating are conducted. The hospital needs according to the types of purchases and their annual volumes of contracts are analyzed. The advantages of competitive procedures are determined and the key factors affecting the level of competition with possible risks of unreliable execution of contracts are identified. The empirical study is based on the database which includes 5390 contracts of 2 hospitals in Moscow for years of 2011–2017. Using the methods of econometric analysis, in particular, the method of least squares and the difference in the average, the hypothesis is tested the high competition has a positive effect on the quality of medical services. The constructed regression models show that the customer providing high quality services has low competition and small rebates at the auction. At the same time there are more contract terms, delays in the supply of goods and services as compared with the customer providing low quality services. Thus it was found that the underestimation of competition at the auction indicates the desire of the hospital to guarantee a higher quality of medical services to patients while as aggressive bids of participants lead to the supply of poor purchases. The results of the study may be useful for the competent authorities in the development of legal acts for the participants of the contract system in the field of health procurement.

Thanks to its physical characteristics, Ultra-wideband (UWB) is one of the most promising technologies for indoor pedestrian navigation. UWB radio localisation systems however experience multipath phenomena that decrease the precision and the reliability of the user's location. To cope with complex indoor environments, UWB radio signals are coupled with inertial measurements from Micro Electro Mechanical Sensors (MEMS) in an extended Kalman filter. Improved performances of the filter are presented and compared with reference trajectories and with pure inertial solutions. Only specific selection methods enable this improvement by detecting and removing outliers in the raw localisation data.

Human Robot Collaboration

Human-robot collaboration is being used more and more in industry applications and is finding its way into medical applications. Industrial robots that are used for human-robot collaboration, cannot detect obstacles from a distance. This paper introduced the idea of using wireless technology to connect a Time-of-Flight camera to off-the-shelf industrial robots. This way, the robot can detect obstacles up to a distance of five meters. Connecting Time-of-Flight cameras to robots increases the safety in human-robot collaboration by detecting obstacles before a collision. After looking at the state of the art, the authors elaborated the different requirements for such a system. The Time-of-Flight camera from Heptagon is able to work in a range of up to five meters and can connect to the control unit of the robot via a wireless connection.
