Handoff Latency Improvement using Multicasting Schemes in Heterogeneous Networks (2006)

Next generation wireless networks are characterized as heterogeneous networks, particularly in terms of its underlying technology. One of the challenges of these heterogeneous networks is to manage handoff. Mobile IP is chosen for managing the handoff to accommodate the all-IP vision of the future interconnected networks. However, the handoff management of the mobile IP is mainly for data services where delay is not of a major concern. Therefore, it would be considerable challenge to achieve low latency handoff for real-time services. In this paper, we propose a multicasting scheme for delay-sensitive applications. The proposed scheme is shown to reduce the latency introduced during the process of mobile IP-based handoff between heterogeneous networks. For low data rate applications, in which real-time voice services operate, the proposed scheme implements an adaptive packet size technique to reduce both the probability of packet loss and the handoff latency. We present simulation results to verify the improvements achieved using the proposed multicasting scheme as opposed to the standard mobile IP

Case Report about mammary analogous secretory carcinoma of Parotid Gland in Germany (2019)

We report about a 24-year-old male patient who was diagnosed with an initially sonographically non-malignant tumor of the right Parotid Gland and with histologically confirmed low grade secretory carcinoma (synonym: mammary analogous secretory carcinoma, MASC) of the Parotid Gland. The patient had no pre-existing conditions or a positive history of noxa. The patient did not complain of B-symptoms, facial paralysis or pain. Only an unclear lesion moderately sized for 4 months was noted, which did not respond to oral antibiotic therapy. After two surgical procedures the tumor could be resected R0. In the interdisciplinary tumor conference a biopsy of unclear hilar and mesenteric lymph nodes showed no malignant. There were no pathological findings. Due to the tumor stage and the tight R0-resection, a postoperative local radiotherapy for the patient has finally been provided.
An FPGA-Based Image Recognition with Remote Update Functions for Autonomous Driving on “ad-refkit” (2021)

This paper explains the ongoing development of an FPGA-based image recognition system for an autonomous driving robot car for the FPT'21 Design Competition. We are developing an FPGA-based image recognition on “ad-refkit” equipped with a Zybo-Z7 board to realize two main functionalities: 1) to provide recognition results in the actual environment of the contest through the Internet and 2) to be updated remotely based on the results. With these functionalities, we can realize high-performance and low-power systems using an FPGA.

these proxies may use the present Diameter rules.
Adaptive digital x-ray detector for high sensitivity medical fluoroscopy imaging (2015)

This work presents a new approach to increase the sensitivity of digital x-ray detectors used for medical fluoroscopy imaging by increasing the signal-to-noise ratio (SNR) of the detected x-ray image signal. The improvement is achieved by recognizing that in some medical imaging scenarios, the object or region of interest that needs to be x-rayed may only cover a fraction of the entire digital x-ray detector imaging array. Our new approach is designed to improve imaging sensitivity by reconfiguring the detector array to capture and display only the small localized portion of the array that the health care provider would like imaged, while simultaneously disabling the unused portion of the imaging array. Using transient TFT leakage current measurements, we show how the detector noise level can be lowered as a function of the number of rows disabled.
Investigation of an Automated Potting Process for High Volume Insert Assembly in Honeycomb Structures (2022)

&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;Threaded, potted inserts are commonly used as a standard connecting element for sandwich components, which are used for aircraft interior. Since they often offer the only detachable connection, they are used in very high quantities. To ensure a material bond between the inserts and the honeycomb structure, the joint is filled with adhesive. Despite the high number of inserts, this process is performed manually. Recent research has shown new approaches for automated gripping and placement of the inserts by an industrial robot that yield high potential for cost savings and increased productivity. Automated adhesive insertion, so-called potting, has not been considered so far but is an essential contribution to the full automation of the entire process chain. The amount of adhesive varies depending on the type of insert and its position on the honeycomb structure. During the potting process, it is also mandatory to prevent air inclusions, to fulfill safety requirements in the aviation industry. This paper presents an approach for automated potting to further increase the degree of automation during sandwich panel production. First, the range of insert types is analyzed and the joint geometries are investigated. Based on the derived requirements, an automation concept is introduced and a parameter study is carried out. Optimal parameters are derived which can be used for process control. Finally, the overall process capability is shown and evaluated using a flexible, automated system.&lt;/div&gt;&lt;/div&gt;
Integrated Interpretation of a Rich Data Set from a New-Generation LWD Tool (2005)

A new logging-while-drilling (LWD) tool combining traditional measurements of gamma ray, propagation resistivity, gamma-gamma density, and thermal-neutron porosity with measurements unique to the LWD arena opens up new opportunities for formation evaluation on LWD. Neutron capture spectroscopy provides elemental concentrations of major rock-forming elements; these can be translated into mineralogy and matrix properties such as matrix density and matrix capture cross section using well-established algorithms.The combination of continuous matrix properties from neutron capture spectroscopy with conventional gammagamma density and enhanced thermal-neutron porosity measurements, and a new capture cross section measurement provide the means to calculate porosity and saturation directly from nuclear measurements. The use of this multiplicity of direct measurements allows for the calculation of accurate porosity and fluid saturations with reduced uncertainty and subjectivity when compared to traditional triple-combo interpretation.The accurate clay fraction derived from neutron capture spectroscopy also allows for enhanced interpretation of saturation from resistivity in shaly sands. The availability of two independent saturation estimates from similar volumes of the formation allows for improved confidence in the water saturations obtained.
Robotic Telemedicine for Mental Health: A Multimodal Approach to Improve Human-Robot Engagement (2021)

COVID-19 has severely impacted mental health in vulnerable demographics, in particular older adults, who face unprecedented isolation. Consequences, while globally severe, are acutely pronounced in low- and middle-income countries (LMICs) confronting pronounced gaps in resources and clinician accessibility. Social robots are well-recognized for their potential to support mental health, yet user compliance (i.e., trust) demands seamless affective human-robot interactions; natural 'human-like' conversations are required in simple, inexpensive, deployable platforms. We present the design, development, and pilot testing of a multimodal robotic framework fusing verbal (contextual speech) and nonverbal (facial expressions) social cues, aimed to improve engagement in human-robot interaction and ultimately facilitate mental health telemedicine during and beyond the COVID-19 pandemic. We report the design optimization of a hybrid face robot, which combines digital facial expressions based on mathematical affect space mapping with static 3D facial features. We further introduce a contextual virtual assistant with integrated cloud-based AI coupled to the robot's facial representation of emotions, such that the robot adapts its emotional response to users' speech in real-time. Experiments with healthy participants demonstrate emotion recognition exceeding 90% for happy, tired, sad, angry, surprised and stern/disgusted robotic emotions. When separated, stern and disgusted are occasionally transposed (70%+ accuracy overall) but are easily distinguishable from other emotions. A qualitative user experience analysis indicates overall enthusiastic and engaging reception to human-robot multimodal interaction with the new framework. The robot has been modified to enable clinical telemedicine for cognitive engagement with older adults and people with dementia (PwD) in LMICs. The mechanically simple and low-cost social robot has been deployed in pilot tests to support older individuals and PwD at the Schizophrenia Research Foundation (SCARF) in Chennai, India. A procedure for deployment addressing challenges in cultural acceptance, end-user acclimatization and resource allocation is further introduced. Results indicate strong promise to stimulate human-robot psychosocial interaction through the hybrid-face robotic system. Future work is targeting deployment for telemedicine to mitigate the mental health impact of COVID-19 on older adults and PwD in both LMICs and higher income regions.

Revisiting the folding kinetics of bacteriorhodopsin (2011)

The elucidation of the physical principles that govern the folding and stability of membrane proteins is one of the greatest challenges in protein science. Several insights into the folding of α-helical membrane proteins have come from the investigation of the conformational equilibrium of H. halobium bacteriorhodopsin (bR) in mixed micelles using SDS as a denaturant. In an effort to confirm that folded bR and SDS-denatured bR reach the same conformational equilibrium, we found that bR folding is significantly slower than has been previously known. Interrogation of the effect of the experimental variables on folding kinetics reveals that the rate of folding is dependent not only on the mole fraction of SDS but also on the molar concentrations of mixed micelle components, a variable that was not controlled in the previous study of bR folding kinetics. Moreover, when the molar concentrations of mixed micelle components are fixed at the concentrations commonly employed for bR equilibrium studies, conformational relaxation in the transition zone is slower than hydrolysis of the retinal Schiff base. As a result, the conformational equilibrium between folded bR and SDS-denatured bR cannot be achieved under the conventional condition. Our finding suggests that the molar concentrations of mixed micelle components are important experimental variables in the investigation of the kinetics and thermodynamics of bR folding and should be accounted for to ensure the accurate assessment of the conformational equilibrium of bR without the interference of retinal hydrolysis.
A new algorithm for the alignment of inertial measurement units without external observation for land vehicle applications (2003)

Describes a real time, on-the-fly, roll and pitch alignment algorithm for inertial measurement units (IMUs) mounted on land vehicles. Unlike conventional strategies, the alignment is achieved without external observations. This is achieved by exploiting the nonholonomic constraints that govern the motion of a vehicle on a surface to obtain the roll and pitch of the IMU. The position of the vehicle along its path is still unobservable and the algorithm is effective only when there is sufficient excitation in all degrees of freedom. However, with the proposed alignment algorithm, the IMU is able to provide sufficiently accurate position information for substantially longer periods of time compared with conventional methods. Experimental results are provided along with a comparison of an IMU/GPS navigation loop showing the effectiveness of the algorithm.
Recommended Standard of Cerebrospinal Fluid Analysis in the Diagnosis of Multiple Sclerosis (2005)

New criteria for the diagnosis of multiple sclerosis (MS) were published as the result of an internationally formed committee. To increase the specificity of diagnosis and to minimize the number of false diagnoses, the committee recommended the use of both clinical and paraclinical criteria, the latter involving information obtained from magnetic resonance imaging, evoked potentials, and cerebrospinal fluid (CSF) analysis. Although rigorous magnetic resonance imaging requirements were provided, the “new criteria paper” fell short in terms of guidelines as to how the CSF analysis should be performed and simply equated the IgG index with isoelectric focusing, without any justification. The spectrum of parameters analyzed and methods for CSF analysis differ worldwide and often yield variable results in terms of sensitivity, specificity, accuracy, and reliability, with no decided “optimal” CSF test for the diagnosis of MS. To address this question specifically, an international panel of experts in MS and CSF diagnostic techniques was convened and the result was this article, representing a consensus of all the participants. These recommendations for establishing a standard for the evaluation of CSF in patients suspected of having MS should greatly complement the new criteria in ensuring that a correctdiagnosisofMSisbeingmade.
The Use of Thermogravimetry in Quantifying the Hydration Products in Cement-Stabilized Kaolinite (2017)

The study presented in this paper was aimed at investigating the use of thermogravimetry (TG) to quantify the amounts of various hydration products, particularly calcium silicate hydrate (CSH) and calcium hydroxide (CH), in stabilized soils and establish correlations between them and strength gain over time. For that purpose, a pure kaolinite was chosen as the soil for this study and Portland cement was the selected stabilizer. Kaolinite samples and cement-stabilized samples were compacted at their optimum conditions and cured for different periods of time up to 90 days. The unconfined compression test, which is a relatively simple and commonly used test, was performed to measure the unconfined compressive strength (UCS) for all the samples and record the macroscopic behavior. Then, a portion of soil from each set of samples was recovered and subsequently subjected to the TG test which was performed at a constant heating rate of 10 K/min until 1000 oC, while being connected to a mass spectrometer (MS) for simultaneous evolved gas analysis. The thermal decomposition was divided into four major regions i) desorption of adsorbed water below 105 oC, ii) dehydration of CSH phases between 105 and 440 oC, iii) dehydroxylation of kaolinite and CH between 440 and 580 oC, and iv) decarbonation of calcium carbonate at temperature between 580 and 1000 oC. The quantitative analysis revealed that strong linear correlations exist between the amounts of CSH and CH, and strength gain.

Metropolitan Segment Traffic Speeds from Massive Floating Car Data in 10 Cities (2023)

Traffic analysis is crucial for urban operations and planning, while the availability of dense urban traffic data beyond loop detectors is still scarce. We present a large-scale floating vehicle dataset of per-street segment traffic information, Metropolitan Segment Traffic Speeds from Massive Floating Car Data in 10 Cities (MeTS-10), available for 10 global cities with a 15-minute resolution for collection periods ranging between 108 and 361 days in 2019-2021 and covering more than 1500 square kilometers per metropolitan area. MeTS-10 features traffic speed information at all street levels from main arterials to local streets for Antwerp, Bangkok, Barcelona, Berlin, Chicago, Istanbul, London, Madrid, Melbourne and Moscow. The dataset leverages the industrial-scale floating vehicle Traffic4cast data with speeds and vehicle counts provided in a privacy-preserving spatio-temporal aggregation. We detail the efficient matching approach mapping the data to the OpenStreetMap road graph. We evaluate the dataset by comparing it with publicly available stationary vehicle detector data (for Berlin, London, and Madrid) and the Uber traffic speed dataset (for Barcelona, Berlin, and London). The comparison highlights the differences across datasets in spatio-temporal coverage and variations in the reported traffic caused by the binning method. MeTS-10 enables novel, city-wide analysis of mobility and traffic patterns for ten major world cities, overcoming current limitations of spatially sparse vehicle detector data. The large spatial and temporal coverage offers an opportunity for joining the MeTS-10 with other datasets, such as traffic surveys in traffic planning studies or vehicle detector data in traffic control settings.
Monte-Carlo Analysis of Asymmetry in Three-Site Relaxation Exchange: Probing Detailed Balance (2023)

Abstract. The question is investigated if three-site diffusive relaxation exchange in thermodynamic equilibrium can lead to exchange maps, which are asymmetric for fluids confined to pores. Asymmetry reports circular flow of particles between the relaxation sites which disagrees with detailed balance according to which the particle exchange between any pair of sites must be balanced. Vacancy diffusion and gas diffusion of particles confined to two-dimensional pores were modeled in Monte-Carlo simulations. For each particle move in vacancy diffusion on a 2D checkerboard grid, one of the eight neighboring destination cells was identified on the basis the jump probability calculated from an empirical approximation of the free energy. Gas diffusion was simulated without thermodynamic interaction on a simulation grid which was up to 104 times finer than the particle diameter. It was found that up to 1 % of all particles moves coherently in closed paths. This motion is attributed to pore resonance corresponding to diffusion eigenmodes. The study shows that detailed balance of multi-site exchange does not apply for a small fraction of particles when the exchange is impacted by topological constraints.
System-Dynamics Approach to Multireservoir Energy Generation under Climate Change (2022)

This paper evaluates several efficiency indexes of hydropower energy generation in Iran’s Karkheh Basin water reservoir system (i.e., Seymareh and Karkheh Rivers) under climate change based on the system dynamics approach. The climate change effects are investigated with simulations of surface temperature and rainfall driven by downscaled climate projections from atmosphere–ocean circulation models in the current literature, and the models with the highest correlation and lowest error for rainfall and temperature in the 1976–2005 baseline period are identified. Rainfall and temperature are projected over two future periods, 2040–2069 and 2070–2099, and are downscaled to basin scale. Results project that the basin temperature over future periods will be higher than in the baseline period. Downscaled results under climate change indicate that rainfall will not follow a specific pattern. An artificial neural network applied to predict runoff indicates that the runoff and flood peak will decrease. Software is implemented to simulate the operation of hydropower reservoirs in baseline and future periods. Five reservoir operation states are considered, with simulation results of energy production showing that runoff and energy production have a complex pattern. Seven indexes of hydropower reservoir efficiency are also calculated for the five operation states corresponding to targets of energy production.
The Effects of UV Light on the Chemical and Mechanical Properties of a Transparent Epoxy-Diamine System in the Presence of an Organic UV Absorber (2017)

Despite several excellent properties including low shrinkage, good chemical resistance, curable at low temperatures and the absence of byproducts or volatiles, epoxy resins are susceptible to ultra violet (UV) damage and their durability is reduced substantially when exposed to outdoor environments. To overcome this drawback, UV absorbers have been usually used to decrease the rate of UV degradation. In this present study, the effects of UV light on the chemical, mechanical and physical properties of cured epoxy structure, as well as the effect of an organic UV absorber, Tinuvin 1130, on the epoxy properties were investigated. Chemical changes in a cured epoxy system as a result of the presence and absence of Tinuvin 1130 were determined using Fourier transform infrared spectroscopy (FT-IR) analyses. The effect of Tinuvin 1130 on the surface morphology of the epoxy systems was also investigated by scanning electron microscopy (SEM) imaging. Additionally, the glass transition temperatures (<i>T</i><sub>g</sub>) before and during UV radiation were measured. After an 800 h UV radiation, mechanical test results revealed that the lack of the UV absorber can lead to a ~30% reduction in tensile strength. However, in the presence of Tinuvin 1130, the tensile strength was reduced only by ~11%. It was hypothesized that the use of Tinuvin 1130, as an organic UV absorber in the epoxy-amine system, could decrease the undesirable effects, arising from exposure to UV light.
A Regularized Method for Selecting Nested Groups of Relevant Genes from Microarray Data (2009)

Gene expression analysis aims at identifying the genes able to accurately predict biological parameters like, for example, disease subtyping or progression. While accurate prediction can be achieved by means of many different techniques, gene identification, due to gene correlation and the limited number of available samples, is a much more elusive problem. Small changes in the expression values often produce different gene lists, and solutions which are both sparse and stable are difficult to obtain. We propose a two-stage regularization method able to learn linear models characterized by a high prediction performance. By varying a suitable parameter these linear models allow to trade sparsity for the inclusion of correlated genes and to produce gene lists which are almost perfectly nested. Experimental results on synthetic and microarray data confirm the interesting properties of the proposed method and its potential as a starting point for further biological investigations.
