Abstract

Chronic inflammation is considered as one of the challenging diseases, and overproduction of reactive oxygen species (ROS) is strongly related to the onset of chronic inflammation. Therefore, antioxidant and anti-inflammatory approaches are particularly becoming suitable treatment and prevention of inflammation. Curcumin (CUR), a main component of turmeric extract, is well known as an effective agent in both antioxidant and anti-inflammatory activities; however, there are still some limitations of its use including poor water solubility, low bioavailability, and oxidation by ROS. Nanotechnology has been used as a drug delivery system, which is a promising approach in overcoming the aforementioned drawbacks of CUR; hence, it improves the antioxidant and anti-inflammatory effects of conventional medications. In this research, silica-containing redox nanoparticles (siRNP) were designed with the size of several tens of nanometers, prepared by self-assembly of an amphiphilic block copolymer consisting of drug absorptive silica moiety and ROS-scavenging nitroxide radical moiety in the hydrophobic segment. CUR was simply encapsulated into siRNP through the dialysis method, creating CUR-loaded siRNP (CUR@siRNP), which significantly improved the water solubility of CUR. The efficient antioxidant activity and anti-inflammatory effect of CUR@siRNP in vitro were also improved via 2,2-diphenyl-1-picrylhydrazyl assay and lipopolysaccharide-induced macrophage cell line activation, respectively. Oral administration of CUR@siRNP showed improvement in pharmacokinetic profile in vivo including AUC and Cmax values as compared to free CUR. Furthermore, the anti-inflammatory effect of nanoformulation was investigated in the colitis mouse model induced by dextran sodium sulfate.

Abstract

Obstacle region detection has been one of the most important tasks for detecting and classifying preceding vehicles moving along the road. Traditional U-V disparity-based obstacle detection methods consider only single disparity pixels to extract obstacle regions. They might fail to produce accurate obstacle regions when noise is encountered in the original disparity map. Recently, local patterns have been successfully applied to handle noise in many systems, such as texture classification and vehicle detection. Therefore, this paper introduces a new approach to compute U and V disparity using maximum local density encoding and ternary pattern features. Our method produced better performance than the existing U-V disparity methods in terms of detection rate and accuracy. In addition, we also evaluated the performance of the proposed method with the Faster RCNN-based object detection. Experimental results show that our method improved the detection rate of Faster RCNN by 1.65% on the KITTI dataset, and by 2.28% on the CCD dataset. In addition, the proposed method also improved the running time of Faster RCNN by 47% on the KITTI dataset.

Abstract

The performance of stereo matching algorithms strongly depends on the quality of the stereo data/matching cost. Most state-of-the-art data costs require expert knowledge for the design of a transformation function, such as census for handling gray-level changes monotonically, adaptive normalized cross correlation for handling Lambertian cases, guided filtering for preserving edge information, and local density encoding for handling illumination differences. However, it is difficult to design a complex transformation function to handle unknown factors that often occur in driving conditions such as snow, rain, and sun. Therefore, this paper has investigated the deep learning strategy to develop a novel stereo matching cost model without using much expert knowledge. Experimental results show that the proposed deep learning model obtains better results than the state-of-the-art stereo matching cost as judged by the standard KITTI benchmark, Middlebury, and HCI datasets.

Abstract

While it is a hot issue whether cars could drive by themselves in emergent situations without any kind of human interference, pedestrian detection is the key technology in autonomous driving cars. Though current pedestrian detection technologies have come to a point in which they are accurate in normal conditions and surroundings, existent systems are inaccurate in harsh situations, such as when there are too many pedestrians, when there is too much light or when it is too dark, or when it is raining or snowing heavily. This problem may be solved by integrating deep learning and combining a new type of local pattern with the RGB raw image as input, instead of using just the RGB image as input. We will introduce a new type of local pattern called Triangular Patterns, which is effective in extracting more detailed and stable features from local regions. Here in this paper, we propose a pedestrian detection system in which deep learning is used, along with combining the RGB raw image with Triangular Patterns for input.

Abstract

We propose a novel fuzzy encoding pattern that fuzzily encodes the relative orders between pixel pairs. An image window is divided into disjoint neighboring pixel sets for the window’s center pixel, and the relative order is established not only between the center pixel and its neighbors but also between the pixel pairs in each neighboring pixel set. The relative orders are fuzzily encoded to extract more detailed information from a local structure. We successfully apply the pattern as a matching cost function for stereo correspondence under severe radiometric variations. We conduct experiments using the proposed matching cost function and compare it with functions employing the census transform, supporting local binary pattern, and adaptive normalized cross correlation, as well as a mutual information-based matching cost function, using different stereo data sets. Compared with the census transform, the proposed function reduces the error from 33.1% to 16.9% in the Middlebury data set and from 17.6% to 9.5% in the Kitti data set. The experimental results indicate that the proposed function is superior to the state-of-the-art functions under radiometric variations. In addition, the proposed function is faster than recently developed functions, such as the adaptive normalized cross correlation, a mutual information-based function, and support local binary pattern.

Abstract

This paper introduces a general framework for detection, recognition, and tracking preceding vehicles and pedestrians based on a deep learning approach. The proposed framework combines a novel deep learning approach with the use of multiple sources of local patterns and depth information to yield robust on-road vehicle and pedestrian detection, recognition, and tracking. The proposed system is first based on robust obstacle detection to identify obstacles appearing along the road that are likely to be vehicles and pedestrians, implemented as an efficient adaptive U-V disparity algorithm. Second, the results from the obstacle detection stage are input into a novel vehicle and pedestrian recognition system based on a deep learning model that processes multiple sources of depth information and local patterns. Finally, the results from the recognition stage are used to track detected vehicles or pedestrians in the next frame by means of a proposed tracking and validation model. The proposed framework has been thoroughly evaluated by inputting several vehicle and pedestrian data sets that were collected under various driving conditions. Experimental results show that this framework provides robust vehicle and pedestrian detection, recognition, and tracking with high accuracy, and also satisfies the real-time requirements of driver assistance systems.

Abstract

Car detection is a crucial issue in self-driving cars. Numerous in-traffic car detection models have been proposed, each of which exhibits its own strengths and weaknesses; the high detection speeds of some models are not accompanied by high precision, while the precision of other models is shadowed by insufficient speeds. Our main goal in this paper is to introduce a model that utilizes the Recurrent Rolling Convolution (RRC). The model gives promising results on detection speed and precision, thereby mitigating the weaknesses of previously proposed models, which is exhibited in our extensive experiment.

Abstract

Pedestrian detection systems have become a crucial topic due to their contribution to numerous applications, such as surveillance, self-driving cars, tracking systems, and robotics. Therefore, we have developed an efficient pedestrian detection algorithm using a support vector machine (SVM) and a histogram of oriented gradients (HOG) feature. This paper introduces a system that is capable of reducing the set of candidate detection regions and classifying pedestrians and non-pedestrians in urban traffic by using the stixel world and HOG + SVM, respectively. The stixel world computation in this proposal is used to compute the region of interest of the input image. We also introduce our new human dataset, including more than 3100 human images, and a method used for classifying the dataset. By implementing on a CPU only, we reach high-quality detection at 56 fps in urban traffic scenarios. Our experimental results demonstrate the effectiveness of reducing the set of detection regions to improve the processing time of our system.

Packaging and Board assembly significantly reduce their RF and mm-Wave performances. A broadband experimental setup is developed for the qualification of packaged switch devices accounting for deembedding effects both with on-board/on-package and on-chip probing. Module-based switch devices have been measured then, plastic molding, Si cap, and bonding wires have been sequentially removed to investigate their influences. Different challenges with packaged switch devices are identified and effective solutions are proposed for their qualification. © 2016 IEEE.

Abstract

International audience; The work is related to an Agile Filter which is a specific RF block to be inserted between an antenna and a first stage of pre-amplification in future on board antenna systems or any future multi-purpose communications terminals. It will be able to process signals in the frequency range between 2 and 18 GHz with target insertion loss below 3dB. The basic idea of the demonstrator studied and developed in this project is to evaluate a SiP approach combining heterogeneous technologies and 3D integration and packaging. This paper presents the process flow used to design, fabricate and integrate in 3D a tunable RF filter which tunability is obtained by the use of MEMS varactors based on a copper on glass technology and stacked on micro-PCD for the electronic control functions. MEMS+ parameterized structures for RF MEMS varactor designs are presented with dimension constraints to be compatible with the space available at the end of each combline sub-filter. Indeed, the MEMS capacitors are composed of a mobile square membrane of 210μm by side and overall size of 600μm. In addition, these RF MEMS tunable capacitor models were automatically transferred into VerilogA for rapid system-level simulation usable further in ADS environment to verify the RF performances.

Goethite rod-like nanoparticles have been successfully synthesized in 10 min of microwave treating at 100 degrees C. Particle size is in the range from 30 to 60 nm in width and from 200 to 350 nm in length. BET analysis indicated that the surface area of the product is 158.31 m(2)g(-1). The feasibility of Cr(VI) removal fromaqueous solution depends on the pH of the solution and contact time. The maximum adsorptionis reached at pH 4.0 and 540 min of contact time. The adsorption kinetics was analyzedby the pseudo-first-and second-order models and the results reveal that the adsorption process obeys the pseudo-second-order model. The adsorption data were fitted well with the Langmuir adsorption isotherm.

Abstract

Clinoptilolite is a natural mineral with exceptional physical characteristics resulting from its special crystal structure, mainstreamed into a large zeolite group called heulandites. An overall view of the research related to the synthesis, modification and application of synthetic clinoptilolite is presented. A single phase of clinoptilolite can be hydrothermally synthesized for 1–10 days in an autoclave from various silica, alumina, and alkali sources with initial Si/Al ratio from 3.0 to 5.0 at a temperature range from 120 to 195 °C. Crystallization rate and crystallinity of clinoptilolite can be improved by seeding. The modification of clinoptilolite has received noticeable attention from the research community, since modified forms have specific properties and therefore their area of application has been broadening. This paper provides a review of the use of organic compounds such as quarter alkyl ammonium, polymer, amine and inorganic species used in the modification process, discusses the processes and mechanisms of clinoptilolite modification, and identifies research gaps and new perspectives.

Abstract

We present SESUB (Semiconductor Embedded in Substrate) and WLCSP (Wafer-Level-Chip-Scale Packaging) integration of Power Combiners for WLAN and 5G applications. The proposed technology solutions offer optimized Electromagnetic-Thermal-Mechanical performances for Energy-Efficient Chip-Package-PCB distributed Co-Design. PDK-Library oriented RLC Lumped-model topologies are compared to broadband distributed Layout design. Prototype demonstrators are designed and experimentally verified for emerging 5G and IoT applications both for frequencies below 6GHz and in the mm-Wave domain (28GHz, 39GHz). Innovative broadband physics-based RLC equivalent circuit models valid from DC to mm-Wave frequencies is proposed and verified against measurement.
