Model of smart solar PV charge controller (2011)

The development of smart solar grids will help to provide concentration of power within the grid and eliminate the power losses seen when panels are working insufficiently. It will also allow switching between panels to provide optimal battery charging. Each panel will be characterized by their open circuit voltage and short-circuit currents. This paper presents approaches to implementation of this idea and various uses which will help analyze the functionality of a smart solar grid in the residential market. In particular, implementation of such a system would allow users to program switching between two, and eventually more, independently controlled solar cells, allowing for optimal battery charging according to the panels' electrical outputs. This platform therefore requires a large portion of programming to be integrated with the solar cells as well as the switching interface. Data will need to be stored and computations made to determine the optimal circuitry configuration. One constraint that is already a problem would be the number of cells which can be continually monitored by the program. More cells require either more time to compute data or a faster data processing center, either of which would cost money in the end. In the case of multiple solar cells producing similar output voltages, more than one switch may need to be turned on therefore allowing multiple solar cells, or panels, to take part in charging the battery. With a large portion of this design based solely on a software interface, it becomes hard to design hardware architecture that allows for faster processing. The limitations of the project are based on the limitations of the software developed. Overall performance increases in battery charging efficiency will help balance out any cost or time constraints that may occur during the implementation of such a project.

Venlafaxine in the treatment of borderline personality disorder. (1995)

A number of studies have indicated that selective serotonin reuptake inhibitors (SSRIs) are effective in reducing the symptomatology accompanying borderline personality disorder (BPD). The SSRIs have proven efficacious in reducing self-injury, suicidality, affective instability, rage, impulsivity, psychosis, and obsessionality. Fluoxetine and sertraline have been shown to be effective in clinical trials, although no single SSRI has emerged as the treatment of choice. Individuals failing one SSRI often respond to another. The data presented in this article indicate that venlafaxine is effective in treating borderline personality disorder (BPD) as an initial intervention and may benefit many individuals for whom fluoxetine or sertraline treatment has failed.
Infrared spectroscopy and transport of electrons in semiconductor superlattices (1995)

Infrared spectroscopy is a powerful tool for revealing some key properties of electrons in the minibands of semiconductor superlattices. Some theoretical foundations of superlattice physics as well as the experimental work on infrared absorption will be reviewed in this article. After a discussion of the energy levels (minibands, donor states) and the effect of external electric and magnetic fields on the miniband structure, a framework for the description of optical transitions between and within minibands is developed. Experiments on inter- and intraminiband as well as on cyclotron resonance absorption are presented in some detail. The most striking phenomena observed in this context are the van Hove singularities in the miniband joint density of states, the thermal quenching of miniband conductivity, and magnetic miniband breakdown. Finally, transport and infrared emission experiments are summarized.
Comments on "Design and analysis of arbitration protocols" by F. El Guibaly (1992)

In the above-titled paper by F. El Guibaly (see ibid., vol.38, p.161-71, (1989)), the (normalized) access time for various arbitration protocols was theoretically characterized. The commenter uses simulations to investigate single-bus multiprocessor arbitration protocols. Differences are found between the theoretical results and the simulation results. Theoretical formulae given by El Guibaly are corrected and modified to take into account that resubmitted requests increase the request rate. Closer agreement between theoretical and simulation results is then obtained.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

A Traffic Prediction Based Bandwidth Management Algorithm of a Future Internet Architecture (2010)

In a internet architecture called CABO, multiple routing architectures can run on a shared physical infrastructure, which is carried out with network virtualization. This paper presents the design and evaluation of a bandwidth allocation algorithm based on multi-commodity flow problem solver integrated with a traffic predictor: linear predictor with dynamic error compensation (L-PREDEC). The basic idea of our design is that some failure in the MFP computation implies that one or more links do not have enough available capacity, which violates the linear constraints on the commodities for each link when modeling MFP. To avoid producing bottleneck links, we employed traffic predictor. On one hand, MFP solver makes better resource utilization by making use of the thin pieces of available bandwidth, by which the virtual network can accept more service requests. On the other hand, the traffic predictor adjusts the link with the largest occupation (bottleneck link) by periodically monitoring the traffic rate of a user link and adjusting the reserved bandwidth based on the prediction made from the traffic history. Then we present the results of performance comparisons of the predictor-integrated algorithm and the allocation algorithm only by Solving MFP. The comparisons are based on the mean packet delay, the variance of the packet delay, and the buffer requirements. Our performance tests show that predictor-integrated algorithm works better than the allocation algorithm only by Solving MFP in terms of the three metrics listed above.
[Peripheral anterior synechiae overlying the haptics of posterior chamber lenses]. (1995)

To study the changes of the anterior chamber angle after intraocular lens implantation, 111 patients (130 eyes) with posterior chamber intraocular lens implantation at different post-operative periods were examined by gonioscopy. Peripheral anterior synechia overlying the position of the lens haptic (lens haptic PAS) was observed in up to 50.8% of eyes implanted with haptics vaulted anteriorly by 10%. The lens haptic PAS is easy to be identified, it is a broad based forward displacement of the peripheral iris adhesive to the anterior wall of the anterior chamber angle. The size of the PAS was of half to one o'clock position and occasionally it was of one and a half to two o'clock position. The differences between the rates of occurrence of lens haptic PAS were not significant at different post-operative periods (P > 0.05). 55.9% of the sulcus fixated and 42.3% of the capsular fixated eyes had lens haptic PAS (P > 0.05). There were more lens haptic PAS in eyes with horizontally oriented lens haptics (62.7%) than with lens haptics at vertical position (41.4%, P < 0.05). Regular gonioscopy for posterior chamber lens implantation was recommended.
MONITORING OF EUROPEAN CONCRETE PAVEMENTS (1995)

As part of the European Concrete Pavement Evaluation System (COPES) program, 77 concrete pavement sections from France, Italy, the United Kingdom, and Belgium are being monitored and the data evaluated with the objective of providing continual improvements to the design, construction, and maintenance of concrete pavements. An overview of the data collected under the European COPES program is presented, and a general look at overall performance trends is provided. The European sections are all characteristic of the wet-freeze environmental region. Because of higher legal axle weights and longer design periods, European pavements are often exposed to many more equivalent-single-axle-load applications than pavements in the United States. Of the sections evaluated, the most common pavement type is jointed plain concrete pavement. Extensive use of stabilized bases, positive drainage features, and dowel bars is also evident. A qualitative analysis was conducted using present serviceability rating (PSR), age, and traffic as the principal parameters. The use of lean concrete bases and incorporation of a greater number of modernity elements (e.g., dowel bars and positive drainage) were found to improve the performance of the sections. Models predicting the PSR of the pavement sections were also developed.

TDAN: Temporally-Deformable Alignment Network for Video Super-Resolution (2020)

Video super-resolution (VSR) aims to restore a photo-realistic high-resolution (HR) video frame from both its corresponding low-resolution (LR) frame (reference frame) and multiple neighboring frames (supporting frames). Due to varying motion of cameras or objects, the reference frame and each support frame are not aligned. Therefore, temporal alignment is a challenging yet important problem for VSR. Previous VSR methods usually utilize optical flow between the reference frame and each supporting frame to warp the supporting frame for temporal alignment. However, both inaccurate flow and the image-level warping strategy will lead to artifacts in the warped supporting frames. To overcome the limitation, we propose a temporally-deformable alignment network (TDAN) to adaptively align the reference frame and each supporting frame at the feature level without computing optical flow. The TDAN uses features from both the reference frame and each supporting frame to dynamically predict offsets of sampling convolution kernels. By using the corresponding kernels, TDAN transforms supporting frames to align with the reference frame. To predict the HR video frame, a reconstruction network taking aligned frames and the reference frame is utilized. Experimental results demonstrate that the TDAN is capable of alleviating occlusions and artifacts for temporal alignment and the TDAN-based VSR model outperforms several recent state-of-the-art VSR networks with a comparable or even much smaller model size. The source code and pre-trained models are released in https://github.com/YapengTian/TDAN-VSR.
Visual search and selective attention (2006)

Abstract Visual search is a key paradigm in attention research that has proved to be a test bed for competing theories of selective attention. The starting point for most current theories of visual search has been Treisman's "feature integration theory" of visual attention (e.g., Treisman & Gelade, Citation1980). A number of key issues that have been raised in attempts to test this theory are still pertinent questions of research today: (1) The role and (mode of) function of bottom-up and top-down mechanisms in controlling or "guiding" visual search; (2) in particular, the role and function of implicit and explicit memory mechanisms; (3) the implementation of these mechanisms in the brain; and (4) the simulation of visual search processes in computational or, respectively, neurocomputational (network) models. This paper provides a review of the experimental work and the—often conflicting—theoretical positions on these thematic issues, and goes on to introduce a set of papers by distinguished experts in fields designed to provide solutions to these issues.

Route to create large-area ordered polymeric nanochannel arrays (2006)

Depositing polymdimethylsiloxane (PDMS) from an isopropanol solution onto a glass slide surface by wiping with a fuzz-free wipe results in highly ordered structures. Dewetting of the highly diluted PDMS solution and evaporation of the solvent yields nanostructures. The structure is well characterized as polymer nanochannels, separated by a mean distance of 166nm. The mean height of the shallow channels is 3nm only. The proof of having aligned structures on very large surface areas with a well defined orientation is performed with a very high resolution grazing incidence small angle x-ray scattering setup.
Comparison of the thiamine level in blood and erythrocyte transketolase activity in hemodialyzed and nondialyzed patients during recombinant human erythropoietin therapy. (1997)

Thiamine and erythrocyte transketolase activity (ETKA) disturbances in end-stage renal disease are caused mainly by uremia and dialysis treatment. We examined whether recombinant human erythropoietin (rhEPO) can correct these abnormalities in uremic patients. Thirteen hemodialysis (HD) and 12 nondialyzed (ND) anemic patients showed decreased free and total thiamine levels in plasma and in erythrocytes and decreased ETKA when compared to 20 healthy subjects. Thiamine blood levels (mumol/l) were determined using a fluorimetric technique, and ETKA (mumol/l per minute) was assessed with a photocolorimetric method. Over 20 weeks of study, rhEPO was given intravenously for 8 weeks at 50 Ul/kg body weight (BW) three times a week, and subcutaneously for 4 weeks at 25 Ul/kg BW, twice a week, and for the last 8 weeks at 25 Ul/kg BW once a week. The correction of anemia was associated with an increase in plasma thiamine and erythrocyte total thiamine as well as ETKA in HD patients and with an increase in erythrocyte total thiamine in ND patients only during the period of intravenous infusions.
Progressive compression of PointTexture images (2004)

In this paper, we develop a tree-structured predictive partial matching (PPM) scheme for progressive compression of PointTexture images. By incorporating PPM with tree-structured coding, the proposed algorithm can compress 3D depth information progressively into a single bitstream. Also, the proposed algorithm compresses color information using a differential pulse coding modulation (DPCM) coder and interweaves the compressed depth and color information effciently. Thus, the decoder can reconstruct 3D models from the coarsest resolution to the highest resolution from a single bitstream. Simulation results demonstrate that the proposed algorithm provides much better compression performance than a universal Lempel-Ziv coder, WinZip.
Trusted Logging for Grid Computing (2008)

The rise of many kinds of grid systems, and associated security threats, makes very necessary the provision of trustworthy services for audit and logging. However, existing solutions tend to put little emphasis on the security of logging. We present a number of use cases where the logs have security properties in their own rights, and so the logs themselves are highly privileged: hence, these need to be integrity and confidentiality protected while being generated, accessed, reconciled and analysed with distributed services spanning across multiple administrative domains. We derive a common set of secure logging requirements to address the security gaps which exist between these use cases and existing solutions.From the requirements, we propose a novel logging architecture for the grid based on virtual machine (VM) isolation and trusted computing capabilities: a small number of privileged driver VMs trigger all trusted logging requests and forward them to the secure logging service running within the log security manager. The logging service verifies the integrity of the log data and the security configurations of these driver VMs (log generators) before storing the logs.
3D vision assisted flexible robotic assembly of machine components (2015)

Robotic assembly systems either make use of expensive fixtures to hold components in predefined locations, or the poses of the components are determined using various machine vision techniques. Vision-guided assembly robots can handle subtle variations in geometries and poses of parts. Therefore, they provide greater flexibility than the use of fixtures. However, the currently established vision-guided assembly systems use 2D vision, which is limited to three degrees of freedom. The work reported in this paper is focused on flexible automated assembly of clearance fit machine components using 3D vision. The recognition and the estimation of the poses of the components are achieved by matching their CAD models with the acquired point cloud data of the scene. Experimental results obtained from a robot demonstrating the assembly of a set of rings on a shaft show that the developed system is not only reliable and accurate, but also fast enough for industrial deployment.
125I-lysergic acid diethylamide binds to a novel serotonergic site on rat choroid plexus epithelial cells (1985)

125I-Lysergic acid diethylamide (125I-LSD) binds with high affinity to serotonergic sites on rat choroid plexus. These sites were localized to choroid plexus epithelial cells by use of a novel high resolution stripping film technique for light microscopic autoradiography. In membrane preparations from rat choroid plexus, the serotonergic site density was 3100 fmol/mg of protein, which is 10-fold higher than the density of any other serotonergic site in brain homogenates. The choroid plexus site exhibits a novel pharmacology that does not match the properties of 5-hydroxytryptamine-1a (5-HT1a), 5-HT1b, or 5-HT2 serotonergic sites. 125I-LSD binding to the choroid plexus site is potently inhibited by mianserin, serotonin, and (+)-LSD. Other serotonergic, dopaminergic, and adrenergic agonists and antagonists exhibit moderate to weak affinities for this site. The rat choroid plexus 125I-LSD binding site appears to represent a new type of serotonergic site which is located on non-neuronal cells in this tissue.
A new architecture for power network in 3D IC (2011)

Providing high vertical interconnection density between device tiers, through silicon via (TSV) offers a promising solution in 3D IC to reduce the length of global interconnection. However, some design issues hinder TSV from volumes of adoption, such as IR drop, thermal dissipation, current delivery per package pin and various voltage domains among tiers. To tackle these problems, the design of power network plays an important role in 3D IC. A new integrated architecture of stacked-TSV and power distributed network (STDN) is proposed in this paper. Our new STDN serves triple roles: power network to deliver larger current and reduce IR drop, thermal network to reduce temperature, and decoupling capacitor network to reduce power noise. As well, it helps to alleviate the limitation of the number of IO power pins. For both single and multiple power domains, the proposed STDN architecture demonstrates good performance in 3D floorplan, IR drop, power noise, temperature, area and even the total length of signal connections for selected MCNC benchmarks.
Role of heat transfer and thermal conductivity in the crystallization behavior of polypropylene‐containing additives: A phenomenological model (2003)

Abstract The thermal conductivity of a filler and the thermal conductivity of a composite made from that filler influence the heat‐transfer process during melt processing. The heat‐transfer process from the melt to the mold wall becomes an important factor in developing the skin–core morphology. These aspects were examined in this study. The thermal conductivity of polypropylene–filler composites was estimated with a standard model for various fillers such as calcium carbonate, talc, silica, wollastonite, mica, and carbon fibers. The rate of cooling under given conditions, including the melting temperature, mold wall temperature, mass of the composite, and filler content, was estimated with standard heat‐transfer equations. The time to attain the crystallization temperature for polypropylene was evaluated with a regression method with differential temperature steps. The crystallization curves were experimentally determined for the different fillers, and from them, the induction period for the onset of crystallization was estimated. These observations were correlated with the expected trends from the aforementioned formalism. The excellent fit of the curves showed that in all these cases, the thermal conductivity of the filler and composite played a dominant role in controlling the onset of the crystallization process. However, the nucleation effects became important in the later stages after the crystallization temperature was attained. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 89: 2994–2999, 2003
Aggregation of Rabbit Blood Platelets Produced in Vitro by Saline “Extract” of Tendons (1963)

Summary Rabbit blood platelet aggregates were produced in vitro by addition of rabbit tendon “extract” to citrated platelet-rich plasma. The aggregating activity was not due to presence of adenosine diphosphate in the “extracts” and was unrelated to blood coagulation. The aggregating principle was destroyed by heating of the “extract” to 60° C for 15 minutes or by incubation with collagenase for 1 hour at 37° C. The aggregating effect was associated with particles which were sedi- mented by centrifugation for 30 minutes at 10,000 G. By means of electron microscopy the particles were identified as cross-striated collagen fibrils.
