Sensor Selection in Distributed Multiple-Radar Architectures for Localization: A Knapsack Problem Formulation (2011)

Widely distributed multiple radar architectures offer parameter estimation improvement for target localization. For a large number of radars, with full resource allocation, the achievable localization minimum estimation mean-square error (MSE) may extend beyond the system predetermined performance goals. In this paper, performance driven resource allocation schemes for multiple radar systems are proposed. Two operational policies are considered. In the first, the number of transmit and receive antennas employed in the estimation process is minimized by effectively selecting a subset of active antennas such that the required MSE performance threshold is attained. In the second, an optimal subset of active antennas of predetermined size is selected such that the localization MSE is minimized. These problems are formulated in a combinatorial optimization framework as a knapsack problem (KP), where the goal is to obtain a performance level with the lowest cost, in terms of active system elements. The Cramer-Rao bound (CRB) is used as a performance metric. Cost parameters, representing operational cost or any other utilization constraints on the antennas, are associated with each of the radars. These are incorporated in the KP formulation, integrating decision making factors in the selection process. Antenna subset selection is implemented through a heuristic algorithm, by successively selecting antennas so as to minimize the performance gap between the temporal CRB and a given MSE goal or a given subset size. The proposed approximate algorithms offer considerable reduction in computational complexity when compared with an exhaustive search. By minimizing the number of operational antennas needed to complete the task, this concept introduces savings in both communication link needs and central processing load, in addition to the operational ones.
Stimulating effect of phosphate ions on the dissolution kinetics of iron oxides in an acidic medium (2013)

The dissolution kinetics of iron oxides FeO, Fe2O3, and Fe3O4 in orthophosphoric acid is studied. The dependence of the rate of Fe2O3 (iron(III) oxide) dissolution on the nature of inorganic acids is examined. The values of the stationary potential in a magnetite electrode-orthophosphoric acid solution system are determined. It is established from the experimental results that the stimulating effect of phosphate ions is related to their influence on the potential at the oxide/solution interface.
Adaptive Quantization Matrices for HD and UHD Display Resolutions in Scalable HEVC (2016)

HEVC contains an option to enable custom quantization matrices, which are designed based on the Human Visual System and a 2D Contrast Sensitivity Function. Visual Display Units, capable of displaying video data at High Definition and Ultra HD display resolutions, are frequently utilized on a global scale. Video compression artifacts that are present due to high levels of quantization, which are typically inconspicuous in low display resolution environments, are clearly visible on HD and UHD video data and VDUs. The default QM technique in HEVC does not take into account the video data resolution, nor does it take into consideration the associated display resolution of a VDU to determine the appropriate levels of quantization required to reduce unwanted video compression artifacts. Based on this fact, we propose a novel, adaptive quantization matrix technique for the HEVC standard, including Scalable HEVC. Our technique, which is based on a refinement of the current HVS-CSF QM approach in HEVC, takes into consideration the display resolution of the target VDU for the purpose of minimizing video compression artifacts. In SHVC SHM 9.0, and compared with anchors, the proposed technique yields important quality and coding improvements for the Random Access configuration, with a maximum of 56.5% luma BD-Rate reductions in the enhancement layer. Furthermore, compared with the default QMs and the Sony QMs, our method yields encoding time reductions of 0.75% and 1.19%, respectively.
Position-Based Adaptive Broadcast for Inter-Vehicle Communications (2008)

With the techniques of wireless communications growing mature, inter-vehicle communications provide an efficient way to improve traffic safety and prevent congestion through exchanging or disseminating the traffic information. Broadcast techniques are usually applied for delivering the emergency messages to drivers but often influenced by the hidden terminal, interference, and contention problems. The paper proposes a new broadcast algorithm which is an event- driven protocol and suitable for cooperative collision avoidance in two-way multi-lane highway. Its message-relaying decisions are made in receiver based on the position, direction, and velocity properties of transmitting and receiving vehicles. The simulation results show that the proposed algorithm delivers the emergency messages efficiently and it has the lower latency and less retransmission than other flooding based protocols.
A Fine-Grained Spatial-Temporal Attention Model for Video Captioning (2018)

Attention mechanism has been extensively used in video captioning tasks, which enables further development of deeper visual understanding. However, most existing video captioning methods apply the attention mechanism on the frame level, which only model the temporal structure and generated words, but ignore the region-level spatial information that provides accurate visual features corresponding to the semantic content. In this paper, we propose a fine-grained spatial-temporal attention model (FSTA), and the spatial information of objects appearing in the video will be our main concern. In the proposed FSTA, we achieve the spatial-hard attention at a fine-grained region level of objects through the mask pooling module and compute the temporal soft attention by using a two-layer LSTM network with attention mechanism to generate sentences. We test the proposed model on two benchmark datasets, namely, MSVD and MSR-VTT. The results indicate that our proposed FSTA model can achieve competitive performance against the state of the arts on both datasets.
High-power high-brightness 980-nm lasers based on the extended cavity surface emitting lasers concept (2003)

We describe design and performance of novel, electrically pumped, vertical compound cavity semiconductor lasers emitting at 980 nm. The laser combines a vertical cavity semiconductor laser with a partially reflecting output coupler and an external cavity for mode control. The concept is scalable and has been demonstrated in monolithic low power (few miliwatts) devices all the way to high power extended cavity devices which generate over 950 mW CW multimode power and 0.5 W CW power in a TEM<sub>00</sub> mode, the latter with 90% coupling efficiency into a single mode telecommunication fiber. The concept has been applied to the development of uncooled lasers, mounted in TO-56 cans, capable of producing 50 to 100 mW of fiber-coupled power. We have also demonstrated the extended cavity lasers at wavelengths of 920 nm and 1064 nm. We present reliability data for the chips used in the extended cavity lasers.
Plasma treatment of polymers: the effect of the plasma parameters on the chemical, physical, and morphological states of the polymer surface and on the metal-polymer interface (1994)

The results of the characterization of plasma-treated polypropylene (PP) and polymethylmethacrylate (PMMA) by X-ray photoelectron spectroscopic, atomic force microscopic (AFM), and surface resistivity measurements are presented. Chemical, physical, and morphological modifications of the polymer surface were investigated. The importance of the neutral gas of the electron cyclotron resonance-radio frequency (ECR-RF) plasma treatment is principally demonstrated. Large differences between the effects of noble and reactive gas plasmas were observed by AFM and surface resistivity measurements. However, the maximum sticking coefficient of evaporated Mg on PP is similar for both Ar and N2 plasma treatments.
Constrained video object segmentation by color masks and MPEG-7 descriptors (2003)

We present an automatic and computationally conservative boundary extraction method using available priori information in a framework consists of change detection mask, region growing, and trajectory motion. Instead of segmenting a entire video frame, only the regions belong to a target object specified by a set of rules are detected. One example of such rules is skin color features of a human body part. The processing domain is limited to the pixels that satisfy color or geometric rules. These rules are represented as a detection mask and implemented as a look-up table. As a result, significant computational reduction and real-time performance are achieved. The framework utilizes color consistency within a centroid-linkage growing technique to grow initial regions. Region seeds are selected among the pixels in the detection mask. The similarity thresholds are adapted from the MPEG-7 dominant color descriptors. The segmentation results of a frame diffused to the next frame and region statistics such as trajectory, percentage of the changed pixels, etc., are registered to determine the moving regions. A computational load comparison of the constrained region growing and regular region growing shows significant reduction in the complexity.
Novel ingestible capsule antenna designs for medical monitoring and diagnostics (2010)

This paper presents novel antenna designs for electronic digestible capsule pill systems. In the first part, a novel conformal planar offset meandered dipole capsule antenna for medical diagnostics is presented. The antenna performance is evaluated by studying the impedance, radiation, polarization and return loss characteristics inside the human body model. A link budget is evaluated to ensure wireless telemetry. In the second part, a novel RFID bio-capsule tag for medical monitoring is presented. The tag performance is evaluated by studying the impedance, radiation pattern and power reflection coefficient characteristics. Finally, a scheme for potential batch fabrication of these capsule antennas is presented.

A novel layout optimization technique has been proposed and adapted to an X-band LNA. The layout pattern of the amplifier has been optimized in only two days by using simple equivalent circuits derived from electromagnetic simulation results. The amplifier has achieved a gain of 35 dB with a noise figure of 1.7 dB. These results have good agreement with simulated results, and the effective chip area is miniaturized to 4.8 mm/sup 2/.
Optimizing Warehouse Forklift Dispatching Using a Sensor Network and Stochastic Learning (2011)

The authors report on a successful deployment of an inexpensive mobile wireless sensor network in a commercial warehouse served by a fleet of forklifts. The aim is to improve forklift dispatching and reduce the costs associated with the delays of loading/unloading delivery trucks. To that end, an integrated system including both hardware and software is constructed. First, the forklifts are instrumented with sensor nodes that collect an array of information, including the forklifts' physical location, usage time, bumping/collision history, and battery status. The hardware's capability is enhanced with a theoretically sound hypothesis testing technique to capture the rather elusive location information, and the collection of the data is done in an efficient event-driven manner. The information acquired combined with inventory information is fed into a sophisticated actor-critic type stochastic learning method to generate dispatching recommendations. Because noise is inevitable in such wireless sensor networks, the performance of the algorithm is investigated under different noise levels. In combining wireless sensing with state-of-the-art decision theory, this work extends beyond the standard use of wireless sensor networks as monitoring devices.
The state of enterprise network traffic in 2012 (2012)

Timely and accurate studies on the composition and nature of the Internet are crucial for continued research and innovation. The aim of this research is to aid and service emulated and simulated research methods where realism is dependent on the accuracy of Internet statistics. This study has captured anonymised, and analysed Internet traffic entering and exiting a university network. Passive measurement techniques are used to discover the mean and distribution of packet sizes. A range of Network and Transport layer statistics, such as DCSP, SACK, ECN, MSS usage, Window Scaling and Timestamps are also investigated. Active measurement techniques are used to determine Round Trip Times (RTTs) and the number of lost and misordered packets. Prior work is leveraged to explore changes in the composition and nature of the Internet over the last 10 years.
Multiview connection technique for 360-deg three-dimensional measurement (2003)

A new multiview connection technique for 360-deg three-dimensional (3-D) measurement is presented. The 3-D shape of a 360-deg object is usually obtained by two steps, first measuring the object from different views and afterward connecting all the views together. We determine the relationship between two adjacent views from their overlapping areas by a least-squares algorithm. To promote computability, the coordinate transform formula is expanded into a Taylor series, and a linear equation system is deduced, from which the relationship parameters between two adjacent views can be easily calculated. According to the resulting parameters, the connection of different views is performed by coordinate transformation in 3-D space. The two steps, parameter calculation and coordinate transformation, are iterated until the algorithm converges or the remaining error decreases below a given threshold. The 360-deg 3-D shape of a plaster statue is measured and reconstructed, thus experimentally demonstrating the validity of suggested method.
Exposing digital forgeries by detecting inconsistencies in lighting (2005)

When creating a digital composite of, for example, two people standing side-by-side, it is often difficult to match the lighting conditions from the individual photographs. Lighting inconsistencies can therefore be a useful tool for revealing traces of digital tampering. Borrowing and extending tools from the field of computer vision, we describe how the direction of a point light source can be estimated from only a single image. We show the efficacy of this approach in real-world settings.
Aging and Synaptic Plasticity: A Review (2002)

Aging affects all systems, but the brain seems to be particularly vulnerable to the action of negative, age‐dependent factors. A gradual loss of memory functions is one of the earliest and most widespread consequences of brain aging. The causes for such impairment are still unclear. Long‐term potentiation (LTP) is one form of neural plasticity, which has been proposed as the cellular correlate for memory. LTP is affected by aging, and such alteration might be causally related to memory dysfunction. In the present paper, we review the evidence sustaining the existence of a causal link between cognitive and LTP impairments, as well as the possible mechanisms involved. New results indicate a possible involvement of a deficient reinforcement of LTP by affective influences.
A Design Method to Improve Temperature Uniformity on Wafer for Rapid Thermal Processing (2018)

Single-wafer rapid thermal processing (RTP) is widely used in semiconductor manufacturing. Achieving temperature uniformity on silicon wafer is a major challenge in RTP control. In this work, a lamp configuration including five concentric lamp zones is designed to obtain uniform temperature distribution on the wafer. An optics-based model is developed to determine the optimal lamp design parameters, and a uniformity criterion is proposed to evaluate the effective irradiance distribution of the tungsten–halogen lamps on the wafer. This method can be used to determine geometric parameters of the lamp array in order to achieve uniform temperature distribution on the wafer. A realistic simulation of a cold wall RTP system with five lamp rings and a 200-mm wafer is performed. The proposed model makes way for a simple method for determining the optimal lamp design parameters in RTP systems.

A study of low-power crystal oscillator design (2013)

UWB backscatter RFID systems require high quality clock signals and crystal oscillator is one of the few candidates. A study of a low-power parallel-mode crystal oscillator for such applications is presented. A 7.8125 MHz Pierce crystal oscillator is realized in a TSMC 90 nm CMOS process. It has a frequency stability of ±7 ppm from 0 to 70°C and draws 36 μW from a 1.2 V supply.

[A case of meningoencephalitis caused by persistent Epstein-Barr (E-B) virus infection]. (1989)

A 44-year-old man had several episodes of tingling sensation in his lower extremities, head and face over 1 year and presented mental disturbance 2 months prior to admission. He additionally suffered from dysuria and acute onset of gait disturbance 18 days before admission. Physical and neurological examination revealed marked splenomegaly, stupor, abnormal behavior, spastic tetraparesis and sphincter disturbances, and meningoencephalitis was suspected. There was lymphocytosis in peripheral blood, some of which showed atypical morphology. CSF examination revealed increased protein content and mononuclear pleocytosis. The titers of antibodies against E-B virus were elevated as follows; VCA IgM (X320), VCA IgG (X20,480), EA (X10,240) and EBNA (X10) in serum, and VCA IgM (X4), VCA IgG (X160), EA (X40) and EBNA (less than 1) in CSF. CT and MRI examination revealed ring enhanced lesion adjacent to left lateral ventricle with surrounding diffuse edema. Administration of intravenous glycerol and oral prednisolone induced substantial improvement in sensory, mental and sphincter disturbances and brain CT findings but not in splenomegaly and pyramidal tract signs. Antibody titer against VCA IgM also decreased. After withdrawal of prednisolone, CSF and CT findings worsened, and the antibody titer became elevated again, and CSF and CT findings improved by readministration of prednisolone. From the above signs and laboratory data, especially continuous elevation of antibody titer against E-B VCA IgM for as long as 1 year, this case was considered to be a meningoencephalitis caused by persistent E-B virus infection.
Organization, regulatory sequences, and alternatively spliced transcripts of the mucosal addressin cell adhesion molecule-1 (MAdCAM-1) gene (1995)

The mucosal addressin cell adhesion molecule-1 (MAdCAM-1) is expressed selectively at venular sites of lymphocyte extravasation into mucosal lymphoid tissues and lamina propria, where it directs local lymphocyte trafficking. MAdCAM-1 is a multifunctional type l transmembrane adhesion molecule comprising two distal lg domains involved in alpha 4 beta 7 integrin binding, a mucin-like region able to display L-selectin-binding carbohydrates, and a membrane-proximal lg domain homologous to lgA. We show in this work that the MAdCAM-1 gene is located on chromosome 10 and contains five exons. The signal peptide and each one of the three lg domains are encoded by a distinct exon, whereas the transmembrane, cytoplasmic tail, and 3'-untranslated region of MAdCAM-1 are combined on a single exon. The mucin-like region and the third lg domain are encoded together on exon 4. An alternatively spliced MAdCAM-1 mRNA is identified that lacks the mucin/lgA-homologous exon 4-encoded sequences. This short variant of MAdCAM-1 may be specialized to support alpha 4 beta 7-dependent adhesion strengthening, independent of carbohydrate-presenting function. Sequences 5' of the transcription start site include tandem nuclear factor-kappa B sites; AP-1, AP-2, and signal peptide-1 binding sites; and an estrogen response element. Our findings reinforce the correspondence between the multidomain structure and versatile functions of this vascular addressin, and suggest an additional level of regulation of carbohydrate-presenting capability, and thus of its importance in lectin-mediated vs alpha 4 beta 7-dependent adhesive events in lymphocyte trafficking.
Social and Discourse Contributions to the Determination of Reference in Cross-Situational Word Learning (2012)

How do children infer the meanings of their first words? Even in infant-directed speech, object nouns are often used in complex contexts with many possible referents and in sentences with many other words. Previous work has argued that children can learn word meanings via cross-situational observation of correlations between words and their referents. While cross-situational associations can sometimes be informative, social cues to what a speaker is talking about can provide a powerful shortcut to word meaning. The current study takes steps toward quantifying the informativeness of cues that signal speakers' chosen referent, including their eye-gaze, the position of their hands, and the referents of their previous utterances. We present results based on a hand-annotated corpus of 24 videos of child-caregiver play sessions with children from 6 to 18 months old, which we make available to researchers interested in similar issues. Our analyses suggest that although they can be more useful than cross-situational information in some contexts, social and discourse information must also be combined probabilistically to be effective in determining reference.
