Capturing, sharing, and discovering product data at a semantic level - moving forward to the semantic web for advancing the engineering product design process (2011)

Along with the greater productivity that CAD automation provides nowadays, the product data of engineering applications needs to be shared and managed efficiently to gain a competitive edge for the engineering product design. However, exchanging and sharing the heterogeneous product data is still challenging. This dissertation first presents a detailed exploration on semantic strategies based on ontology models for integrating product data between multiple engineering applications, including two typical CAD applications in Product Design Domain, and one CAE application in Assembly Simulation Domain. It is concluded that the semantic approach is superior for exchanging and sharing heterogeneous product data at a semantic level.
Further, this dissertation postulates an approach to introduce reasoning capability into the engineering ontologies in product assembly domain to truly exploit this logic-based and formal representation for product data. A layered architecture for semantic applications containing reasoning units is proposed. Retrieval specifications and inference rules in SWRL/SQWRL are defined in these reasoning units. It is concluded that the reasoning mechanism extends the semantic representation made possible through the ontology and holds promise for improving design knowledge understanding and discovery.
Finally, based on research achievements on ontology modeling and reasoning, this dissertation presents an online Product Design Semantic Knowledge Management System (PD-SKMS) for presenting, querying/reasoning, and authoring/updating product data semantics by incorporating Semantic Web technologies. The Product Semantic Repositories (PSR) in a Host Hybrid-Data Repository (HDR) preserves product data semantics for the product assembly domain. A Semantic Data Management Engine (SDME) provides querying/reasoning and authoring/updating services on PSRs. By linking to public linked data, the capability of PD-SKMS is extended to external data sources. It is concluded that the PD-SKMS delivers an interactive and knowledgecontextual design environment for the engineers on the Web and it greatly improves the traditional behaviors for exchanging and sharing product design knowledge.
In summary, this dissertation proposes, discusses, and implements semantic approaches to support design activities for capturing, sharing, and discovering product data semantics in a knowledge-contextual environment. Several practical scenarios successfully demonstrate the proposed approaches and reveal the great potential of semantic approaches for advancing the traditional engineering product design process.
A methodology for OLTP micro-architectural analysis (2017)

Micro-architectural analysis is critical to investigate the interaction between workloads and processors. While today's aggressive out-of-order processors provide a rich set of performance events for deep execution cycle analysis, OLTP characterization studies usually use a cache-miss-based method (CMBM). In this work, we investigate the validity and the functionality of CMBM by comparing it with Intel's state-of-the-art Top-down Micro-architecture Analysis Method (TMAM) for OLTP workloads. We show that, while CMBM and TMAM provide a similar high-level micro-architectural behavior, it is inadequate for a fine-grained micro-architectural analysis. We further show that TMAM underestimates memory stalls. We optimize TMAM's execution cycle breakdown, and improve its estimation of memory stalls up to 50%.
Twenty-Five Years of Signal Processing Advances for Multiantenna Communications: From theory to mainstream technology (2023)

Wireless communication technology has progressed dramatically over the past 25 years, in terms of societal adoption as well as technical sophistication. In 1998, mobile phones were still in the process of becoming compact and affordable devices that could be widely utilized in both developed and developing countries. There were “only” 300 million mobile subscribers in the world <xref ref-type="bibr" rid="ref1" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">[1]</xref> . Cellular networks were among the first privatized telecommunication markets, and competition turned the devices into fashion accessories with attractive designs that could be individualized. The service was circumscribed to telephony and text messaging, but it was groundbreaking in that, for the first time, telecommunication was between people rather than locations.
The pathogenesis of Yersinia enterocolitica gastroenteritis. (1979)

Of nine Y. enterocolitica serotypes examined by us, only type 3 was shown to be enteropathogenic. 3 of 16 strains recovered from clinical material, produced a heat-stable toxin similar to that reported in E. coli. A fourth isolate produced histological changes resembling those associated with salmonellae. The mechanism whereby the majority of Y. enterocolitica strains produce diarrhoea is uncertain. Our isolates may have lost a plasmid essential for enteropathogenicity, or they may resemble the 'classical' enteropathogenic strains of E. coli for which no satisfactory experimental model exists. Further studies on freshly isolated strains are in progress in order to determine the prevalence of enterotoxigenic Y. enterocolitica.
Maternal Effects on Fatty Acid Composition of Soybean Seed Oil (2010)

ABSTRACT The success of genetically altering the fatty acid composition of soybean ( Glycine max (L.) Merr.) seed oil is determined by the rate of genetic gain through selection. Maternal effects can influence genetic gain. Objectives of this study were to investigate the presence and magnitude of maternal effects on fatty acid content of soybean oil. Maternal effects for unsaturated fatty acid content were evaluated over 2 yr using reciprocal F 1 soybean seed from crosses between the mid‐oleic/low‐linolenic line ‘N98‐4445A’ and six cytoplasmically diverse cultivars. Maternal effects were significant across genetically diverse materials and likely the result of the phenotype of the maternal plant. The magnitude of the maternal effect was typically less when N98‐4445A was used as the maternal parent. These data suggest that selection based on the oil composition of single F 2 seeds might be ineffective but less so if the altered fatty acid parent is the maternal parent. Maternal effects on saturated fatty acid content were evaluated both in the field and in vitro using reciprocal F 1 soybean seed from the cross between the high‐palmitic line ‘N02‐4441’ and ‘Dare’. Maternal effects were significant when grown in the field. When reciprocal F 1 and parental 25 d old embryo seeds were grown in vitro, maternal effects between reciprocal crosses were not apparent, while significant differences between the parents were maintained. This suggests that factors translocated from the maternal plant may be causing the maternal effect on developing F 1 seeds.
Tissue-specific transcriptional profiles and heterogeneity of natural killer cells and group 1 innate lymphoid cells (2022)

Natural killer (NK) cells and type 1 innate lymphoid cells (ILC1s) are populations of non-T, non-B lymphocytes in peripheral tissues. Although NK and ILC1 subsets have been described, their identification and characteristics remain unclear. We performed single-cell RNA sequencing and CITE-seq to explore NK and ILC1 heterogeneity between tissues. We observed that although NK1 and NK2 subsets are conserved in spleen and liver, ILC1s are heterogeneous across tissues. We identified sets of genes expressed by related subsets or characterizing unique ILC1 populations in each organ. The syndecan-4 appeared as a marker discriminating murine ILC1 from NK cells across organs. Finally, we revealed that the expressions of EOMES, GZMA, IRF8, JAK1, NKG7, PLEK, PRF1, and ZEB2 define NK cells and that IL7R, LTB, and RGS1 differentiate ILC1s from NK cells in mice and humans. Our data constitute an important resource to improve our understanding of NK-ILC1 origin, phenotype, and biology.
An L1 Cache Design Space Exploration System for Embedded Applications (2009)

In an embedded system where a single application or a class of applications is repeatedly executed on a processor, its cache configuration can be customized such that an optimal one is achieved. We can have an optimal cache configuration which minimizes overall memory access time by varying the three cache parameters: the number of sets, a line size, and an associativity. In this paper, we first propose two cache simulation algorithms: CRCB1 and CRCB2, based on Cache Inclusion Property. They realize exact cache simulation but decrease the number of cache hit/miss judgments dramatically. We further propose three more cache design space exploration algorithms: CRMF1, CRMF2, and CRMF3, based on our experimental observations. They can find an almost optimal cache configuration from the viewpoint of access time. By using our approach, the number of cache hit/miss judgments required for optimizing cache configurations is reduced to 1/10-1/50 compared to conventional approaches. As a result, our proposed approach totally runs an average of 3.2 times faster and a maximum of 5.3 times faster compared to the fastest approach proposed so far. Our proposed cache simulation approach achieves the world fastest cache design space exploration when optimizing total memory access time.

A model predictive method for efficient power ramp rate control of wind turbines (2012)

A model predictive method is proposed to control the power ramp rate of a wind turbine system integrated with ultracapacitors as its high power, short-term, energy storage. In this method, it is assumed that the wind turbine output power can be predicted within a predefined horizon time interval. The proposed method involves two steps. First, the total stored energy required to maintain a preset power ramp rate during the prediction horizon time is calculated. Should the value of the calculated energy exceed the storage capacity, the power ramp rate is incremented gradually until the storage system can supply the required energy. Next, the prediction horizon is shifted forward by a desirable time interval and the previous step is repeated. It is shown that the expansion of the prediction time interval decreases the average power ramp, enhancing the efficiency of the proposed method.

Hamiltonian-Driven Adaptive Dynamic Programming With Approximation Errors (2021)

In this article, we consider an iterative adaptive dynamic programming (ADP) algorithm within the Hamiltonian-driven framework to solve the Hamilton-Jacobi-Bellman (HJB) equation for the infinite-horizon optimal control problem in continuous time for nonlinear systems. First, a novel function, "min-Hamiltonian," is defined to capture the fundamental properties of the classical Hamiltonian. It is shown that both the HJB equation and the policy iteration (PI) algorithm can be formulated in terms of the min-Hamiltonian within the Hamiltonian-driven framework. Moreover, we develop an iterative ADP algorithm that takes into consideration the approximation errors during the policy evaluation step. We then derive a sufficient condition on the iterative value gradient to guarantee closed-loop stability of the equilibrium point as well as convergence to the optimal value. A model-free extension based on an off-policy reinforcement learning (RL) technique is also provided. Finally, numerical results illustrate the efficacy of the proposed framework.
Antibacterial Narrow‐Band‐Gap Conjugated Oligoelectrolytes with High Photothermal Conversion Efficiency (2017)

Abstract Two conjugated oligoelectrolytes (COEs), WMG1 and WMG2, were designed with the goal of achieving near infrared absorption and high photothermal conversion efficiency. Specifically, electron‐rich thiophene and electron‐poor benzo[1,2‐c:4,5‐c′]bis[1,2,5]thiadiazole subunits were introduced into the conjugated core to modulate the optical gap and to reduce the fluorescence emission efficiency. WMG1 and WMG2 show absorption maxima at around 800 nm, which favors tissue penetration. Although relatively small in size, WMG1 and WMG2 exhibit photothermal conversion efficiencies of circa 60 % and 54 %, respectively. WMG1 shows dark toxicity to the Gram positive bacterium B. subtilis and good photothermal killing efficiency toward both B. subtilis and Gram negative E. coli , features that demonstrate the promising potential of the COE molecular design for photothermal applications.
On the transient phase of balanced SSFP sequences (2003)

The signal intensity of balanced steady-state free precession (SSFP) imaging is a function of the proton density, T(1), T(2), flip angle (alpha), and repetition time (TR). The steady-state signal intensity that is established after about 5*T(1)/TR can be described analytically. The transient phase or the approach of the echo amplitudes to the steady state is an exponential decay from the initial amplitude after the first excitation pulse to the steady-state signal. An analytical expression of the decay rate of this transient phase is presented that is based on a simple analysis derived from the Bloch equations. The decay rate is a weighted average of the T(1) and T(2) relaxation times, where the weighting is determined by the flip angle of the excitation pulses. Thus, balanced SSFP imaging during the transient phase can provide various contrasts depending on the flip angle and the number of excitation pulses applied before the acquisition of the central k-space line. In addition, transient imaging of hyperpolarized nuclei, such as (3)He, (129)Xe, or (13)C, can be optimized according to their T(1) and T(2) relaxation times.

Enhancing the solar still using immersion type water heater productivity and the effect of external cooling fan in winter (2012)

In the present work an attempt is made to enhance the of double slope solar stillproductivity by an immersion type water heaterusing. The effect of using an external fan to cool the glass surface is also examined. Experiments were carried out for winter season in Saudi Arabian climatic conditions at latitude 26° N. A solar still with 35° glass slope angle is chosen in our study. Since the yield of a solar still is more for low water depths, the water level in the base tank was maintained at 1 cm. The experimental results showed that the productivity increased by a significant 370% when two water heaters each having 500 W capacities was used. When external cooling fan was used the productivity was found to decrease by 4 and 8% for wind speeds of 7 and 9 m/s respectively. Thermal modeling was also doneby the heat and mass transfer relationsusing, and then numerical simulations were carried out to validate with the experimental results. A good agreement between experimental and numerical results was found. The present study is partial implementation of two patents submitted in this field.

Interactions of Platelet Factor 4 with the Vessel Wall (2004)

Platelet factor 4 (PF4) is a platelet-specific protein that is stored in platelet alpha granules and released following platelet activation. PF4 was the first chemokine that was isolated, but unlike other chemokines, it may not have a clear role in inflammation. Gathering evidence suggests that unlike other chemokines that bind to specific receptors, PF4's biology depends on its unusually high affinity for heparan sulfates and other negatively charged molecules at concentrations attained in the immediate vicinity of activated platelets. There has been one report that PF4 binds to CXCR3B, a chemokine receptor isoform that may be present in some vascular beds, but the biological relevance of this single observation is not clear. We propose that the main biological role of PF4 and the basis for its presence in the alpha granules of all known mammalian platelets is to neutralize surface heparan sulfate side-chains of glycosaminoglycans and to optimize thrombus development at sites of vascular injury. In addition, the binding of PF4 to surface glycosaminoglycans may also underlie its angiostatic and proatherogenic properties. Additionally, PF4 binds to several other proteins that are central to thrombosis, angiogenesis, and atherogenesis. These interactions may also contribute to its biological and pathobiological effects. Certainly, future studies using in vivo models to test biological relevance of each of these proposed mechanisms by which PF4 interacts with the vasculature are needed, as are studies to define the importance of PF4 binding to CXCR3B.

Thermal-aware sensor scheduling for distributed estimation (2013)

A sensor network is a distributed system where sensor nodes autonomously collect local data and collaborate to solve global problems. Recent work has shown that sensor functionality varies with node temperature. Extreme temperatures can decrease node/network lifetime by leading to premature hardware failure and reducing battery capacity. Furthermore, high temperatures can increase sensor measurement noise and disrupt communication between overheated sensor nodes, thereby interfering with their ability to contribute valuable information to collaborative tasks. In the past, sensor networks only consisted of low-end devices with limited power, computational capabilities, and available bandwidth. Such devices would only experience high temperatures in harsh environments. However, sensor networks are now envisioned for applications that require higher-end devices, such as smart cameras, smart phones, and laptops. The power dissipated by such devices is much larger than low-end sensors and can create thermal emergencies in sensor hardware even in calm environments. In this article, we present unique management opportunities for distributed estimation tasks in sensor networks consisting of high-end devices prone to thermal issues. We attempt to balance both thermal- and performance-related constraints by examining trade-offs between sensor sampling rate, number of sensors, node temperature, and state estimation error. Initially, we devise a scheduling algorithm which can achieve a desired real-time performance constraint while maintaining a thermal limit on temperature assuming identical nodes in the network. Then, we extend the concept to a network consisting of heterogeneous sensor nodes. Analytical results and simulation experiments are done for state estimation with a Kalman filter for simplicity, but our main contributions should easily extend to any form of estimation with measurable error. Results show that our policies can successfully balance the trade-offs between thermal- and performance-related constraints. Note that our analyses, schemes, and results are less applicable to low-end sensors whose operation does not cause high node temperature. This work is most suited for high-performance sensors and upper-tier sensors which experience greater workloads.
