A High-Performance Vision System for Obstacle Detection (1997)

I have developed a method for obstacle detection in a highway environment using the CMU Video Rate Multi-Baseline Stereo Machine. One key feature of this method is the computation and output of a confidence measure at each pixel, so that regions of the scene with low reliability can be recognized and filtered out. This method has proven to be capable of detecting 3Oanhigh obstacles at distances of close to 100m. Unfortunately, the system requires significant of post-processing of the output data from the CMU stereo machine, and therefore cannot be run in realtime. Additionally, the design of the CMU stereo machine imposes several limitations on the system, both computationally (limited resolution, speed, and programmability) and practically (large size, cost, power consumption). I propose to construct a system, consisting of both hardware and software, to perform this obstacle detection task in real-time. In the process, I will develop a general-purpose stereo vision machine that improves upon the state-of-the-art. Furthermore, I will show that the system can perfom obstacle detection in real-world environments and thus improve vehicle safety.
Prevalence of motor‐skill impairment in preterm children who do not develop cerebral palsy: a systematic review (2009)

Children born preterm are at increased risk of motor impairment, with prevalence three to four times greater than in the general population. This highlights the need for improved surveillance and intervention strategies in this group of children.
Comprehensive Review on Alzheimer’s Disease: Causes and Treatment (2020)

Alzheimer's disease (AD) is a disorder that causes degeneration of the cells in the brain and it is the main cause of dementia, which is characterized by a decline in thinking and independence in personal daily activities. AD is considered a multifactorial disease: two main hypotheses were proposed as a cause for AD, cholinergic and amyloid hypotheses. Additionally, several risk factors such as increasing age, genetic factors, head injuries, vascular diseases, infections, and environmental factors play a role in the disease. Currently, there are only two classes of approved drugs to treat AD, including inhibitors to cholinesterase enzyme and antagonists to <i>N</i>-methyl d-aspartate (NMDA), which are effective only in treating the symptoms of AD, but do not cure or prevent the disease. Nowadays, the research is focusing on understanding AD pathology by targeting several mechanisms, such as abnormal tau protein metabolism, β-amyloid, inflammatory response, and cholinergic and free radical damage, aiming to develop successful treatments that are capable of stopping or modifying the course of AD. This review discusses currently available drugs and future theories for the development of new therapies for AD, such as disease-modifying therapeutics (DMT), chaperones, and natural compounds.
Markerless kinematic model and motion capture from volume sequences (2003)

An approach for model-free markerless motion capture of articulated kinematic structures is presented. This approach is centered our method for generating underlying nonlinear axes (or a skeleton curve) from the volume of an arbitrary rigid-body model. We describe the use of skeleton curves for deriving a kinematic model and motion (in the form of joint angles over time) from a captured volume sequence. Our motion capture method uses a skeleton curve, found in each frame of a volume sequence, to automatically determine kinematic postures. These postures are then aligned to determine a common kinematic model for the volume sequence. The derived kinematic model is then reapplied to each frame in the volume sequence to find the motion suited to this model. We demonstrate our method for several types of motion from synthetically generated volume sequences with arbitrary kinematic topology and human volume sequences captured from a set of multiple calibrated cameras.

Ruthenium complexes as precursors for chemical vapor-deposition (CVD) (2014)

The progress in precursor chemistry for the chemical vapor deposition of ruthenium containing thin films is reviewed.
The genetics of Parkinsonʼs disease (1999)

Since the first description of Parkinson's disease in 1817 there have been numerous attempts to clarify the relative contribution of hereditary and environmental factors in its aetiology. Epidemiological and case-control studies as well as the existence of families with monogenic Parkinson's disease point clearly to a genetic contribution. Insights into the genetic basis of Parkinson's disease will lead to a greater understanding of the condition at a molecular level which will in turn allow the development of new rational therapeutic option.
Phase Composition of Reduced and Reoxidized Barium Titanate (1969)

Reducing high‐purity BaTiO 3 in hydrogen for 1 h at 1275°C leads to an oxygen deficiency x = 0.0036 in BaTiO 3–x with maintenance of the tetragonal/cubic perovskite‐type structure. Reduction at 1325° C leads to x = 0.0073 and brings about transformation to the hexagonal modification. Up to 1500°C ( x = 0.0233) no further phase change occurs. Annealing the oxygen‐deficient hexagonal phase in oxygen at 850° C for 2 h produces stoichiometric samples which are still hexagonal, whereas the tetragonal/cubic structure is restored by heating for 1 h at 1350°C. The unit cell found for the hexagonal phase is somewhat smaller than previously reported.
ACOUSTIC WAVE MEASUREMENTS AT ELEVATED TEMPERATURE USING A PULSED LASER GENERATOR AND AN ELECTROMAGNETIC ACOUSTIC TRANSDUCER DETECTOR (1994)

A wide bandwidth non-contacting ultrasonic system is described For the measurements of acoustic wave velocities in metals at elevated temperatures. A Neodymium: Yttrium Aluminium Garnet (Nd:YAG) pulsed laser was used as the ultrasound generator and a water-cooled Electromagnetic Acoustic Transducer (EMAT) that is sensitive to radial motion in the plane of the sample surface, acts as the receiver. Various laser ultrasound generation mechanisms have been evaluated to obtain simultaneously both the longitudinal and shear wave signals. Measurements have been made on mild steel, a copper alloy and aluminium-silicon alloys to a maximum temperature of about 1100° C. The results obtained have demonstrated that the system can be used to make acoustic wave measurements not only at elevated temperature but also in the fully molten state.
Context Specific Next Location Prediction (2014)

The rapid evolution and proliferation of mobile devices, mobile Internet access and social networks facilitate the development of intelligent services that build on the knowledge of the next location of a mobile user. The prediction of the next location of a mobile user, among others based on spatial, temporal, and in particular social influence factors, is the subject of this dissertation.
Sub-Microwatt Analog VLSI Support Vector Machine for Pattern Classification and Sequence Estimation (2004)

An analog system-on-chip for kernel-based pattern classification and sequence estimation is presented. State transition probabilities conditioned on input data are generated by an integrated support vector machine. Dot product based kernels and support vector coefficients are implemented in analog programmable floating gate translinear circuits, and probabilities are propagated and normalized using sub-threshold current-mode circuits. A 14-input, 24-state, and 720-support vector forward decoding kernel machine is integrated on a 3mm×3mm chip in 0.5µm CMOS technology. Experiments with the processor trained for speaker verification and phoneme sequence estimation demonstrate real-time recognition accuracy at par with floating-point software, at sub-microwatt power. 1

Dither--a way to reduce undesirable fright behavior in ethological studies. (1968)

Zusammenfassung

Wie stark Fluchtstimmung (“Furcht”) das Verhalten von Versuchstieren in ethologischen Untersuchungen storen kann, ist zwar wohl vielen bekannt, wird aber selten erortert oder in Veroffentlichungen erwahnt.



Die Beobachter setzen die Tiere meist entweder der vollen Storung durch den Laborbetrieb aus oder schliesen sie weitestgehend von allen moglichen Storreizen ab. Im ersten Fall fehlt die Kontrolle uber wichtige Storfaktoren, im zweiten werden vor allem Wirbeltiere oft so furchtsam, das sie das meiste Verhalten unterdrucken.



In Untersuchungen an verschiedenen Fischarten hat sich folgender Ausweg sehr bewahrt: Man setzt zum Versuchstier hinter eine durchsichtige Trennwand andersartige Tiere, die sich standig gleichmasig bewegen, fur das Versuchstier aber ohne Interesse sind.
Nonlinear control applied to gearshifting in automated manual transmissions (2002)

In this paper the problem of automating the gearshift process of a manual transmission without synchronizers is investigated. The application is very interesting from an integrated powertrain control point of view, since it includes many different control tasks and encourages the use of the engine as an actuator to the rest of the powertrain. A model-based control law for the task of gearshifting is presented. The controller is designed based on the backstepping methodology. It includes control laws for transmission torque control as well as for engine speed control. Simulations have shown good results for the gearshift controller.
The emerging role of stimulator of interferons genes signaling in sepsis: Inflammation, autophagy, and cell death (2018)

Stimulator of interferons genes (STING) is an adaptor protein that plays a critical role in the secretion of type I interferons and pro-inflammatory cytokines in response to cytosolic nucleic acid. Recent research indicates the involvement of the STING pathway in uncontrolled inflammation, sepsis, and shock. STING signaling is significantly up-regulated in human sepsis, and STING agonists are suggested to contribute to the pathogenesis of sepsis and shock. Nevertheless, little is known about the consequences of activated STING-mediated signaling during sepsis. It has been shown that aberrant activation of the STING-dependent way can result in increased inflammation, type I interferons responses, and cell death (including apoptosis, necroptosis, and pyroptosis). In addition, autophagy modulation has been demonstrated to protect against multiple organs injuries in animal sepsis model. However, impaired autophagy may contribute to the aberrant activation of STING signaling, leading to uncontrolled inflammation and cell death. Here we present a comprehensive review of recent advances in the understanding of STING signaling, focusing on the regulatory mechanisms and the roles of this pathway in sepsis.

Current Assays to Determine Free 25-Hydroxyvitamin D in Serum (2017)

The 25-hydroxylated metabolite of vitamin D is the best clinical indicator of vitamin D status. For many years, emphasis has been on measuring total levels of 25-hydroxyvitamin D [25(OH)D], but recently, interest in measuring free 25(OH)D as a potentially better marker of vitamin D status has arisen. Since the 1980s when the first measurements of free 25(OH)D were made, little progress has been made in the development of rapid, reliable methods to determine the levels of free 25(OH)D. For many years, assessment of free 25(OH)D relied on calculations using levels of total 25(OH)D, albumin, and vitamin D binding protein (VDBP), for which many assays exist. However, because of vagaries in the measurement of VDBP in particular and the assumption of a constant affinity of VDBP for the vitamin D metabolites (which has been shown to be problematic), calculated values have proved suspect. This changed a few years ago when a new immunoassay was developed to measure free 25(OH)D directly. This review examines methods for determining free 25(OH)D, the different methods used in clinical studies, and the relationships between free 25(OH)D and other vitamin D metabolites and the physiologic functions affected by vitamin D metabolites, such as bone cell activity and turnover. The review also comments on the value of assessing free 25(OH)D and the efforts to standardize the assays.

Performance and Stability of Aerosol-Jet-Printed Electrolyte-Gated Transistors Based on Poly(3-hexylthiophene) (2013)

We report performance optimization and stability analysis of aerosol-jet-printed electrolyte-gated transistors (EGTs) based on the polymer semiconductor poly(3-hexylthiophene) (P3HT). EGTs were optimized with respect to printed P3HT thickness and the completed device annealing temperature. EGTs with relatively thin P3HT films (∼50 nm) annealed at 120 °C have the best performance and display an unusual combination of metrics including sub-1-V operation, ON/OFF current ratios of 10(6), OFF currents of <10(-10) A (<10(-6) A cm(-2)), saturation hole mobilities of 1.3 cm(2) V(-1) s(-1), threshold voltages of -0.3 V, and subthreshold swings of 70 mV decade(-1). Furthermore, optimized EGTs printed on polyester substrates are extremely robust to bias stress and repeated mechanical bending strain. Collectively, the results suggest that optimized P3HT-based EGTs are promising devices for printed, flexible electronics.
IRRADIATION BEHAVIOR OF HIGH-BURNUP URANIUM--PLUTONIUM ALLOY PROTOTYPE FUEL ELEMENTS. (1968)

did not appear to vary appreciably with minor changes in Zr or fissium content. Decreasing the Pu to 10 wt%, however, significantly improved the swelling behavior of the alloy. Both pourcast and thermally cycled material and pour-cast, extruded, and thermally cycled material appeared to be more stable under irradiation than injection-cast material. Under comparable irradiation conditions, the specimens of U-20 wt% Pu- 5 wt% Mo alloy were less dimensionally stable than the U-Pu-fissium alloys investigated. (auth)
NetVM: High Performance and Flexible Networking Using Virtualization on Commodity Platforms (2015)

NetVM brings virtualization to the Network by enabling high bandwidth network functions to operate at near line speed, while taking advantage of the flexibility and customization of low cost commodity servers. NetVM allows customizable data plane processing capabilities such as firewalls, proxies, and routers to be embedded within virtual machines, complementing the control plane capabilities of Software Defined Networking. NetVM makes it easy to dynamically scale, deploy, and reprogram network functions. This provides far greater flexibility than existing purpose-built, sometimes proprietary hardware, while still allowing complex policies and full packet inspection to determine subsequent processing. It does so with dramatically higher throughput than existing software router platforms. NetVM is built on top of the KVM platform and Intel DPDK library. We detail many of the challenges we have solved such as adding support for high-speed inter-VM communication through shared huge pages and enhancing the CPU scheduler to prevent overheads caused by inter-core communication and context switching. NetVM allows true zero-copy delivery of data to VMs both for packet processing and messaging among VMs within a trust boundary. Our evaluation shows how NetVM can compose complex network functionality from multiple pipelined VMs and still obtain throughputs up to 10 Gbps, an improvement of more than 250% compared to existing techniques that use SR-IOV for virtualized networking.
A Transform for Logic Networks (1969)

The transform presented in this paper applies to functions which describe logic network behavior. Given a function G defined over a finite domain, it is shown that G(u) = Et F(t)ut for each element u in the domain, where finite-field arithmetic is assumed. Here, function F is the transform of G, and it is shown that F(t) = Eu G(u)(-u)-t for each integer t in a finite set. Both form and development of this transform pair resembles the Fourier transform in harmonic analysis.
Hydrogel-Forming Microneedle Arrays Allow Detection of Drugs and Glucose In Vivo: Potential for Use in Diagnosis and Therapeutic Drug Monitoring (2015)

We describe, for the first time the use of hydrogel-forming microneedle (MN) arrays for minimally-invasive extraction and quantification of drug substances and glucose from skin in vitro and in vivo. MN prepared from aqueous blends of hydrolysed poly(methyl-vinylether-co-maleic anhydride) (11.1% w/w) and poly(ethyleneglycol) 10,000 daltons (5.6% w/w) and crosslinked by esterification swelled upon skin insertion by uptake of fluid. Post-removal, theophylline and caffeine were extracted from MN and determined using HPLC, with glucose quantified using a proprietary kit. In vitro studies using excised neonatal porcine skin bathed on the underside by physiologically-relevant analyte concentrations showed rapid (5 min) analyte uptake. For example, mean concentrations of 0.16 μg/mL and 0.85 μg/mL, respectively, were detected for the lowest (5 μg/mL) and highest (35 μg/mL) Franz cell concentrations of theophylline after 5 min insertion. A mean concentration of 0.10 μg/mL was obtained by extraction of MN inserted for 5 min into skin bathed with 5 μg/mL caffeine, while the mean concentration obtained by extraction of MN inserted into skin bathed with 15 μg/mL caffeine was 0.33 μg/mL. The mean detected glucose concentration after 5 min insertion into skin bathed with 4 mmol/L was 19.46 nmol/L. The highest theophylline concentration detected following extraction from a hydrogel-forming MN inserted for 1 h into the skin of a rat dosed orally with 10 mg/kg was of 0.363 μg/mL, whilst a maximum concentration of 0.063 μg/mL was detected following extraction from a MN inserted for 1 h into the skin of a rat dosed with 5 mg/kg theophylline. In human volunteers, the highest mean concentration of caffeine detected using MN was 91.31 μg/mL over the period from 1 to 2 h post-consumption of 100 mg Proplus® tablets. The highest mean blood glucose level was 7.89 nmol/L detected 1 h following ingestion of 75 g of glucose, while the highest mean glucose concentration extracted from MN was 4.29 nmol/L, detected after 3 hours skin insertion in human volunteers. Whilst not directly correlated, concentrations extracted from MN were clearly indicative of trends in blood in both rats and human volunteers. This work strongly illustrates the potential of hydrogel-forming MN in minimally-invasive patient monitoring and diagnosis. Further studies are now ongoing to reduce clinical insertion times and develop mathematical algorithms enabling determination of blood levels directly from MN measurements.
Flow cytometric analysis of chlorhexidine action (2006)

The mechanism by which chlorhexidine kills bacteria is still ill defined. We have investigated the action of chlorhexidine on Escherichia coli JM101/psb311 using a combination of flow cytometry and traditional methods. Chlorhexidine-induced uptake by E. coli cells of bis-(1,3-dibutylbarturic acid) trimethine oxonol and propidium iodide, which monitor membrane potential and membrane integrity respectively, was shown to be concentration dependent for the range 0.003-0.3 mmol-1. In addition, cells in log phase growth were more susceptible to 0.03 mmol-1 chlorhexidine than those in stationary phase. There was, however, no direct correlation between dye uptake and decline in colony forming units.
Tetramethoxysilane as a precursor for focused ion beam and electron beam assisted insulator (SiO<i>x</i>) deposition (1996)

Focused ion beams are intensively used for device modification by local material removal and ion beam induced metal deposition. With shrinking dimensions on modern multilayer devices, the need for ion beam induced insulator deposition is increasing. In this article, tetramethoxysilane as a precursor for ion beam induced deposition has been investigated. The influence of beam parameters dwell time and loop time on the material deposition rate will be discussed and compared to model calculations. For optimized scanning conditions, a maximum deposition rate of 0.33 μm3/nC was found. Insulating films were also deposited using an electron beam. The chemical composition and electrical properties of these films were compared with the films deposited by the ion beam. For electron beam deposition, the resistivity of the deposited films was 1×106 Ω cm which is two orders of magnitude higher than for ion beam deposited film.
The basic physics of radiation therapy (1976)

It has been thirteen years since the publication of the second edition and twenty-nine years since the first edition. In this third edition, all material has undergone rewriting (with few exceptions). All text type and tables have been completely reset. Illustrations have been revised and many new ones added and there is a larger page size to better accommodate them.
Development of the digital public address system (2012)

In this paper, we developed a digital, minimized and integrated PA system with speech recognition and sensor connection based on IP with an ID. It has facilities such as an external input, a microphone and a radio for a PA system and has speech recognition. If “fire” is spoken to the PA system then it can recognize the emergency situation and will broadcast information to the appropriate agency immediately. In addition to that, many sensors, such as temperature, humidity, and infrared, etc., can be connected to the PA system and can be integrated with the context awareness which contains many types of information about internal statuses. Also, developing the digital integrated PA system with operational MICOM will make it possible to control the facilities of the digital devices centrally. Finally, the digital PA system is designed for operation from a PC, which makes installation and setting of operating parameters very simple and user-friendly.
