Abstract:
In the face of the fact that the development of traditional silicon-based electronic devices is increasingly limited, single molecule electronic device, which has been attracting more and more attention, is considered as one of the most hopeful candidates to realize the miniaturization of conventional electronic devices. In this paper, an overview of single molecule electronic devices is provided, including molecular electronic devices and electrode types. First, several molecular electronic devices are presented, including molecular diodes, molecular memories, molecular wires, molecular field effect transistors (FET) and molecular switches. Then the influence of different electrode types of the transport characteristics is introduced, showing that graphene is a promising electrode material for single molecule electronic devices. Moreover, other excellent characteristics of molecular devices are briefly introduced, such as potential thermoelectric effects, new thermally induced spin transport phenomena and negative differential resistance (NDR) behavior. Finally, the future challenges to the development of electronic devices based on single molecules are described.

Abstract:
The design features of medical electronic devices are considered. It is shown that the development of medical electronics is not an easy task and the designer must be prepared to face problems and regulations that are more strict than for household appliances, due to the fact that the failure of these devices to work properly can lead to tragic consequences, up to death. A number of difficulties that arise in the process of designing medical equipment is shown, which is presented in the form of a hierarchy of decisions. The main standards for designing devices of such type are given, among which there are IEC-60601-1-1 and IEC-60601-1-2 that deserve special attention, since compliance with their requirements is crucial for certification and release to the market of manufactured equipment. The use of a risk management matrix is proposed, which is used to provide quantitative indicators for each possible risk associated with a medical device in any mode of operation and possible malfunction.

Abstract:
A well-documented issue in healthcare is the unsatisfactory level of competence in the effective and safe use of medical devices among practicing healthcare professionals. The roots of the problem lie in the fact that medical devices are developing at a much faster rate than the requisite educational provision. As a result, undergraduate healthcare students carry out their medical device training under the supervision of practitioners-trainers who are themselves not sufficiently competent, creating a vicious circle where lack of competence breeds further incompetence. This circle can only be broken if the practitioner-trainers themselves are educated. However, owing to clinical workload the latter often cannot attend face-to-face educational programs. The problem can be resolved through online learning. This article expounds on the issue and describes an online programme by which the present author is attempting to address the problem.

Abstract:
In recent years, the piezoelectric jet and atomization devices have exhibited tremendous advantages including their simple construction, and the fact that they are discreet and portable as well as low cost. They have been widely used in cell printing, spray cooling, drug delivery, and other industry fields. First, in this paper, two different concepts of jet and atomization are defined, respectively. Secondly, based on these two concepts, the piezoelectric jet and atomization devices can be divided into two different categories: piezoelectric micro jet device and piezoelectric atomization device. According to the organizational structure, piezoelectric micro jet devices can be classified into four different models: bend mode, push mode, squeeze mode, and shear mode. In addition, their development history and structural characteristics are summarized, respectively. According to the location of applied energy, there are two kinds of piezoelectric atomization devices, i.e., the static mesh atomization device and the vibration mesh atomization device, and both their advantages and drawbacks are discussed. The research achievements are summarized in three aspects of cell printing, spray cooling, and drug delivery. Finally, the future development trends of piezoelectric jet and atomization devices are prospected and forecasted.

Abstract:
The paper describes the working principles for six types of separation devices mentioned in the literature, as well as two original types of separation devices devised by the author. In fact the functionality of each device presented in the paper is based on the difference between the friction coefficients – sliding friction for non-spherical particles and rolling friction for spherical ones, respectively. Due to this peculiarity, the two types of particles move along different trajectories, thus becoming separable. The paper also discusses the limit conditions ensuring the functionality of each separation device.

Abstract:
Bacterial biofilms are involved in most device-associated infections and remain a challenge for modern medicine. One major approach to addressing this problem is to prevent the formation of biofilms using novel antimicrobial materials, device surface modification or local drug delivery; however, successful preventive measures are still extremely limited. The other approach is concerned with treating biofilms that have already formed on the devices; this approach is the focus of our manuscript. Treating biofilms associated with medical devices has unique challenges due to the biofilm’s extracellular polymer substance (EPS) and the biofilm bacteria’s resistance to most conventional antimicrobial agents. The treatment is further complicated by the fact that the treatment must be suitable for applying on devices surrounded by host tissue in many cases. Nanomaterials have been extensively investigated for preventing biofilm formation on medical devices, yet their applications in treating bacterial biofilm remains to be further investigated due to the fact that treating the biofilm bacteria and destroying the EPS are much more challenging than preventing adhesion of planktonic bacteria or inhibiting their surface colonization. In this highly focused review, we examined only studies that demonstrated successful EPS destruction and biofilm bacteria killing and provided in-depth description of the nanomaterials and the biofilm eradication efficacy, followed by discussion of key issues in this topic and suggestion for future development.

Abstract:
In spite of the fact that risk management has developed into an essential component of the process of developing medical devices, as mandated by both domestic and international regulations and standards, there is still no all-encompassing model that describes how risk management in the development of medical devices ought to be approached, particularly in terms of the types of risks that ought to be addressed. This is due to the fact that risk management has developed into an essential component of the process, which is mandated by both domestic and international regulations and standards. The present focus of risk management in the industry of developing medical devices is on technical risks, such as product, usability, and development process hazards. This is done in compliance with the norms and laws of standards. On the other hand, non-technical risks, such as those associated with businesses and projects, are not given nearly enough consideration. This review focuses on the risk management in medical device industry.

Abstract:
This paper is about the interplay between multiple modes of valuation. The paper engages with the question of how a valuation device intersects with the working values of an organization. While the many studies of valuation practices have drawn attention to the pervasive effects of valuation devices, only a few studies have taken into account the fact that many spaces, including organizations, are already filled with practices and ideas that constitute what is valuable. Revisiting classical organization theory, this paper shows that organizations comprise multiple, more—or less—integrated modes of valuation. Empirically, the paper draws on an ethnographic study of Lean management at a children’s hospital, which is presented through analytical snapshots. The paper suggests that an organizational turn is relevant for valuation studies, as this fi rst allows an analytical expansion to include less ‘deviced’ valuations, contributes to the ongoing culture vs. device debate offering an alternative to the causal analysis of devices and effects without making the ‘ineffable culture’ what makes or breaks the causality.

Abstract:
Lokal politik har en viktig roll i samhället och dess faktakonstruktion kan ha en påverkan på individen. Lokalpolitikern konstruerar i sina anföranden beskrivningar av verkligheten som görs trovärdiga genom retoriskt arbete. Arbetet använder en diskurspsykologisk metod för att undersöka kommunpolitikers anförande i debatten rörande kommunens styrdokument, Inriktning, verksamhet och ekonomi (förkortat IVE) för åren 2015 till 2018. Studien kommer fram till att problem och lösningar görs till fakta genom användandet av offensiv och defensiv retorik. I konstruerandet av problemet finns också ett konstruerande av en politisk motståndare som föranlett problemet. Producerandet görs trovärdigt genom retoriska resurser som främst är av offensiv karaktär. I konstruerandet av lösningar positionerar kommunpolitiker sig nära lösningen och som kapabla och ansvarsfulla aktörer. I producerandet nyttjas retoriska resurser som främst är av defensiv karaktär.
Local government has an important role in society and their facts construction can have an impact on the individual citizen. In their speeches, local politicians construct descriptions of reality that are made credible by their rhetorical work. This study utilizes a discourse psychological method to investigate municipal politicians’ speech in the debate on the municipal policy regarding Orientation, Services and Economics (abbreviated IVE) for the years of 2015 throughout 2018. The study concludes that problems and solutions become facts through utilization of offensive and defensive rhetorical techniques. In the construction of the problem there is also a construction of the political opponent that has prompted the problem. The production is made credible through rhetorical resources of primarily offensive characteristics. In constructing the solution the municipal politicians position themselves close to the solution and as capable and responsible actors. In the production they use rhetorical resources that are mainly in defensive form.

Abstract:
Liquid crystal (LC) has been widely used for displays, spatial light modulators, variable optical attenuators (VOAs) and other tunable photonic devices. The response time of these devices is mainly determined by the employed liquid crystal material. How to obtain fast response for the LC devices is a fundamentally important and technically challenging task. In this dissertation, we investigate several methods to improve liquid crystal response time, for examples, using dual-frequency liquid crystals, polymer stabilized liquid crystals, and sheared polymer network liquid crystals. We discover a new class of material, denoted as sheared polymer network liquid crystal (SPNLC) which exhibits a submillisecond response time. First, dual-frequency liquid crystals and polymer network methods are demonstrated as examples for the variable optical attenuators. Variable optical attenuator (VOA) is a key component in optical communications. Especially, the sheared PNLC VOA shows the best result; its dynamic range reaches 43 dB while the response time is in the submillisecond range at 1550 nm wavelength, which is 50 times faster than the commercial LC-based VOA. Second, we report a new device called axially-symmetric sheared polymer network liquid crystals (AS-SPNLC) and use it as LC devices. An axially-symmetric sheared polymer network liquid crystal has several attractive features: 1) it is polarization independent, 2) it has gradient phase change, and 3) its response time is fast. It can be used for polarization converter and divergent LC lens. In addition, a new method for simultaneously measuring the phase retardation and optic axis of a compensation film is demonstrated using an axially-symmetric sheared polymer network liquid crystal. This simple technique can be used for simultaneously measuring the optic axis and phase retardations of both A- and C-plates. These compensation films have been used extensively in wide-view LCD industry. Therefore, this method will make an important impact to the LCD industry.

Abstract:
Waveguide discontinuities are frequently encountered in modern photonic structures. It is important to characterize the reflection and transmission that occurs at the discontinuous during the design and analysis process of these structures. Significant effort has been focused upon the development of accurate modelling tools, and a variety of modelling techniques have been applied to solve this kind of problem. Throughout this work, a Transmission matrix based Bidirectional Beam Propagation Method (T-Bi-BPM) is proposed and applied on the uncoated facet and the single coating layer reflection problems, including both normal and angled incident situations. The T-Bi-BPM method is developed on the basis of an overview of Finite Difference Beam Propagation Method (FD-BPM) schemes frequently used in photonic modelling including paraxial FD-BPM, Imaginary Distance (ID) BPM, Wide Angle (WA) BPM and existing Bidirectional (Bi) BPM methods. The T-Bi-BPM establishes the connection between the total fields on either side of the coating layer and the incident field at the input of a single layer coated structure by a matrix system on the basis of a transmission matrix equation used in a transmission line approach. The matrix system can be algebraically preconditioned and then solved by sparse matrix multiplications. The attraction of the T-Bi-BPM method is the potential for more rapid evaluation without iterative approach. The accuracy of the T-Bi-BPM is verified by simulations and the factors that affect the accuracy are investigated.

Abstract:
Liquid crystal (LC)-based adaptive optics are important for information processing, optical interconnections, photonics, integrated optics, and optical communications due to their tunable optical properties. In this dissertation, we describe novel liquid crystal photonic devices and their fabrication methods. The devices presented include inhomogeneous polymer-dispersed liquid crystal (PDLC), polymer network liquid crystals (PNLC) and phase-separated composite film (PSCOF). Liquid crystal/polymer composites could exist in different forms depending on the fabrication conditions. In Chap. 3, we demonstrate a novel nanoscale PDLC device that has inhomogeneous droplet size distribution. In such a PDLC, the inhomogeneous droplet size distribution is obtained by exposing the LC/monomer with a non-uniform ultraviolet (UV) light. An electrically tunable-efficiency Fresnel lens is devised for the first time using nanoscale PDLC. The tunable Fresnel lens is very desirable to eliminate the need of external spatial light modulator. Different gradient profiles are obtained by using different photomasks. The nanoscale LC droplets are randomly distributed within the polymer matrix, so that the devices are polarization independent and exhibit a fast response time. Because of the small droplet sizes, the operating voltage is higher than 100 Vrms. To lower the driving voltage, in Chap. 2 and Chap. 3, we have investigated a polymer-network liquid crystal (PNLC) using a rod-like monomer structure. Since the monomer concentration is only about 5%, the operating voltage is below 10 Vrms. The PNLC devices are polarization dependent. To overcome this shortcoming, stacking two cells with orthogonal alignment directions is a possibility. In Chap. 3, another approach to lower the operating voltage is to use phase-separated composite film (PSCOF) where the LC and polymer are separated completely to form two layers. Without multi-domain formed in the LC cell, PSCOF is free from light scattering. Using PNLC and PSCOF, we also demonstrated LC blazed grating and Fresnel lens. The diffraction efficiency of these devices is continuously controlled by the electric field. Besides Fresnel lens, another critical need for imaging and display is to develop a system with continuously tunable focal length. A conventional zooming system controls the lens distance by mechanical motion along the optical axis. This mechanical zooming system is bulky and power hungry. To overcome the bulkiness, in Chap. 4 we developed an electrically tunable-focus flat LC spherical lens which consists of a spherical electrode imbedded in the top flat substrates while a planar electrode on the bottom substrate. The electric field from the spherical and planar electrodes induces a centrosymmetric gradient refractive index distribution within the LC layer which, in turn, causes the focusing effect. The focal length is tunable by the applied voltage. A tunable range from 0.6 m to infinity is achieved. Microlens array is an attractive device for optical communications and projection displays. In Chap. 5, we describe a LC microlens array whose focal length can be switched from positive to negative or vise versa by the applied voltage. The top spherical electrode glass substrate is flattened with a polymer layer. The top convex substrate and LC layer work together like a zoom lens. By tuning the refractive index profile of the LC layer, the focal length of the microlens array can be switched from positive to negative or vise versa. The tunable LC microlens array would be a great replacement of a conventional microlens array which can be moved by mechanical elements. The fast response time feature of our LC microlens array will be very helpful in developing 3-D animated images. A special feature for LC/polymer composites is light scattering. The concept is analogous to the light scattering of clouds which consist of water droplets. In Chap. 6, we demonstrate polymer network liquid crystals for switchable polarizers and optical shutters. The PNLC can present anisotropic or isotropic light scattering behavior depending on the fabrication methods. The use of dual-frequency liquid crystal and special driving scheme leads to a sub-millisecond response time. The applications for display, light shutters, and switchable windows are emphasized. Although polymer networks help to reduce liquid crystal response time, they tend to scatter light. In Chap. 7, for the first time, we demonstrate a fast-response and scattering-free homogeneously-aligned PNLC light modulator. Light scattering in the near-infrared region is suppressed by optimizing the polymer concentration such that the network domain sizes are smaller than the wavelength. As a result, the PNLC response time is ~300X faster than that of a pure LC mixture except that the threshold voltage is increased by ~25X. The PNLC cell also holds promise for mid and long infrared applications where response time is a critical issue.

Abstract:
This thesis report details a project to extend the AdGateway product developed at Dohi Sweden with a framework that allows advertisers to create interactive advertisements. The key feature of this framework is to provide augmented reality capabilities by taking advantage of face recognition and webcams on smart TV systems. The interactive advertisements are created as applications in JavaScripts which get downloaded on the fly when a user clicks on a banner for that type of advertisement. This implementation will both extend the back-end system to support the distribution of this new type of advertisement as well as the front-end for the supported devices in order to set up the environment and run the JavaScript application. The Sony Google TV is the primary focus for the implementation but an extensive study is also included in the report to gather information about other possible platforms that could be supported. This report also studies in detail how the performance of face recognition can be improved by performing illumination normalization on input images. The project could not be completed on time due to limitations in both hardware and software regarding face detection. Nevertheless a framework has been implemented, and solutions for the impediments are discussed in the report

Abstract:
AbstractNowadays, infections associated with urinary tract medical devices, have become a common health issue. The fact that their surfaces are prone to microbial colonization and biofilm formation is certainly a problem. As a result, these medical devices usage can be a source of extreme concern, especially for critically ill patients. Urinary tract related infections are among the most frequent HAIs comprising 27% in Europe and 36–40% in the USA. Among multiple strategies to fight those infections, biosurfactants as glycolipids can be a valuable tool for biofilm inhibition or disruption. In particularly, multiple in vitro studies concerning sophorolipids and rhamnolipids confirms the antimicrobial activity of those compounds. Further, sophorolipids or rhamnolipids potential role to prevent biofilm associated infections, using different surfaces like medical grade silicone as an example of common material used in catheters and stents fabrication, shows the capacity of those biosurfactants in reducing the adhesion and biofilm formation. Overall, sophorolipids and rhamnolipids due to their multiple antimicrobial/anti-adhesive effects might be an interesting approach to fight urinary tract medical devices associated infections.

Abstract:
AbstractSide-channel attacks (SCAs) are powerful attacks based on the information obtained from the implementation of cryptographic devices. Profiling side-channel attacks has received a lot of attention in recent years due to the fact that this type of attack defines the worst-case security assumptions. The SCA community realized that the same approach is actually used in other domains in the form of supervised machine learning. Consequently, some researchers started experimenting with different machine learning techniques and evaluating their effectiveness in the SCA context. More recently, we are witnessing an increase in the use of deep learning techniques in the SCA community with strong first results in side-channel analyses, even in the presence of countermeasures. In this chapter, we consider the evolution of profiling attacks, and subsequently we discuss the impacts they have made in the data preprocessing, feature engineering, and classification phases. We also speculate on the future directions and the best-case consequences for the security of small devices.

Abstract:
Privacy and security are two items being woven into the fabric of American law concerning mobile devices. This chapter will review and analyze the associated laws and policies that are currently in place or have been proposed to ensure proper execution of security measures for mobile and other devices while still protecting individual privacy. This chapter will address the fact that as the American society significantly uses mobile devices, it is imperative to understand the legal actions surrounding these technologies to include their associated uses. This chapter will also address the fact that with 9/11 in the not so distant past, cyber security has become a forefront subject in the battle against global terrorism. Furthermore, this chapter will examine how mobile devices are not like the devices of the past as the computing power is on par with that of some desktops and the fact that these devices have the ability to execute malicious applications. In addition, this chapter will discuss the reality, significance, legal and practical affects of the fact that suspicious programs are being executed offensively and security based attacks can be performed as well with the use of programs such as Kali Linux running on Android.

Abstract:
Abstract We report on the development of a novel thermography technique, integrated Raman – IR thermography, illustrated here on AlGaN/GaN electronic devices. As it is a generic technique future application to Si, GaAs and other devices is anticipated. While IR thermography can provide fast temperature overviews, its current use for many of today’s technologies is complicated by the fact that it does not provide the spatial resolution needed to probe sub-micron/micron size active device areas. Integrating IR with micro-Raman thermography, providing temperature information with ~0.5 µm spatial resolution, enables unique thermal analysis of semiconductor devices to a level not possible before. This opens new opportunities for device performance and reliability optimization, and failure analysis of modern semiconductor technology, in research, development, and quality control / manufacturing environments.

Abstract:
The subject of fluid dynamics of microfluidic devices such as instability, droplet formation, and control has gained considerable momentum in recently years. This is due partially to the fact that modern developments in the design and utilization of microfluidic devices for fluid transport have found many applications such as drug design and diagnostic devices in biomedicine and microdrop generators for image printing. Furthermore, the new development of nonlinear dynamics of droplets has created a new paradigm of scaling and instability theory that opened a new approach to this classic phenomenon. The utility of a microfluidic device is linked directly to its ability to control microdroplets in precision and speed for desired functionalities. An example of such a device is Kodak’s Continuous Inkjet System, which is capable of stimulating drop breakup of jets of complex fluids with unprecedented precision, speed, and selectivity. We will utilize such a microfluidic device to discuss some of the fluid dynamics topics in microfluidic devices, and to illustrate that the fluid dynamic behavior of such a device is not only influenced by the device architecture, but also by the fluidic properties and by the way the fluid is energized to induce the drop formation and movement. The topics will include a discussion of fluid properties relative to jet modulation, wavelength dependencies, thermal modulation schemes, satellite drop formation, and aerodynamic effects.

Micro-electro-mechanical systems (MEMS) and its younger “brother” nano-electro-mechanical systems (NEMS) are fast growing fields. In fact, in many areas, it is now at a turning point from the initial phase of device concept research and prototyping to volume manufacturing. To large extent, this transition is due to better general understanding of MEMS devices, materials and processes, major advances in packaging methods, and, as a result, significantly improved reliability characteristics up to billions of operation cycles.

Abstract:
Environmental conditions can have major influence on the lifetimes and reliability of active implantable medical devices (e.g., neurostimulators, cochlear implants, internal cardioverter defibrillators). These environmental conditions can range from those encountered by the device in processing and production to transportation and storage to actual operation. Although one might argue that the environmental conditions found in the first two situations are harsher than those of the third, failures that result from those situations are screened before implantation. If we assume that the active medical device is in perfect operational form at the time it is implanted, it will still experience a host of environmental conditions that can affect reliability. In fact, the ultimate goal of these medical devices is to restore the patient, wherever they may reside, to normal activities. A list of some environmental conditions that may be experienced by a device implanted in a representative patient is found in Table 1.

Abstract:
Optoelectronic integrated circuits (OEICs) are expected to perform a broad range of high-performance functions in optical interconnects, optical signal processors, and, eventually, optical computers. Performance advantages are also expected for optical switching matrices and high-speed optoelectronic repeaters. The incompatibility of electronic and optical devices usually requires additive growth techniques, which the layer structures are grown in sequence (fabrication is by selective removal), or by multiple growth techniques, in which layer sequences are grown selectively by removal of the previous sequence. We describe a new approach in which a single high precision molecular-beam epitaxial growth provides a single-quantum-well inversion-channel structure from which lasers, detectors, and transistors are formed with a single device processing sequence. In this approach the optical source detector and transistor are, in fact, the same device structure which is used differently, depending on its application. The transistor is the heterostructure field-effect transistor (HFET) and the detector is the heterostructure field-effect detector (HFED). The laser is a bistable switching device with large optical and electrical gain or is the three-terminal HFET laser. The operation and latest results on all of these devices will be presented.

Abstract:
Abstract This paper addresses two questions related to electrical characterization of devices at the contact level in a semiconductor failure analysis: Is it possible to use scanning electron microscope/focused electron beam based probing system to do electrical characterization at device level despite the fact that there is beam induced device degradation? What are the effects to consider if a beam exposed sample has to be characterized by a nano-probing technique during the failure analysis flow? To answer these questions, an experimental setup with a drive transistor of a single port SRAM manufactured in a 90nm CMOS process was employed. Results confirmed the effect of electron beam induced alteration on integrated devices and it was shown that several parameters influence the investigated device, e.g., beam acceleration voltage and dose used for radiation. The alteration was due to trapped charge located in the gate oxide and also electrons trapped in interface states.

Abstract:
Currently, to evaluate the dynamic characteristics of objects, quite a large number of devices are used in the form of chronographs, which consist of various optical, thermal and laser sensors. Among the problems of these devices, the following can be distinguished: the lack of recording of the received data; the inaccessibility of taking into account the trajectory of the object flying in the sensor area, as well as taking into consideration the trajectory of the object during the approach to the device frame. The signal received from the infrared sensors is recorded in a separate document in txt format, in the form of a table. When you turn to the document, data is read from the current position of the input data stream in the specified list by an argument in accordance with the given condition. As a result of reading the data, it forms an array that includes N number of columns. The array is constructed in a such way that the first column includes time values, and columns 2...N- the value of voltage . The algorithm uses cycles that perform the function of deleting array rows where there is a fact of exceeding the threshold value in more than two columns, as well as rows where the threshold level was not exceeded. The modified array is converted into two new arrays, each of which includes data from different sensor frames. An array with the coordinates of the centers of the sensor operation zones was created to apply the Pythagorean theorem in three-dimensional space, which is necessary for calculating the exact distance between the zones. The time is determined by the difference in the response of the first and second sensor frames. Knowing the path and time, we are able to calculate the exact speed of the object. For visualization, the oscillograms of each sensor channel were displayed, and a chronograph model was created. The chronograph model highlights in purple the area where the threshold has been exceeded.
