Video OCR is a technique that can greatly help to locate topics of interest in large digital news video archive via the automatic extraction and reading captions annotations. News generally provide vital search information about being presented, names people places or descriptions objects. In this paper, two difficult problems character recognition for videos are addressed: low resolution characters extremely complex backgrounds. We apply an interpolation filter, multi-frame integration...
Abstract Infrared absorption spectra of the systems silica gel - H216O,D216O,H218O, and some organic vapors were measured in order to assign bands senstive adsorption at 870 around 950 cm−1. Deuteration caused decrease cm−1 appearance a band 620 The appearing by not only water but also showed no shift on deuteration, shifted toward low frequency side 25 substitution 16O surface silanol groups with 18O. From these facts 870, assgned Si–OH bending, Si–OD bending Si–O stretching vibrations...
We developed a rapid method for concentrating and measuring radiocesium (134Cs 137Cs) dissolved in fresh water using nonwoven fabric impregnated with Prussian blue (PB) as absorber combination gamma-ray spectrometry germanium (Ge) detector. Utilizing this method, 20–100 L freshwater sample could be concentrated within period of 20–60 min by passing the through 10–12 columns, connected series, that had been fitted disks PB. Laboratory tests samples containing known amounts confirmed overall...
Disulfide-bridged binuclear ruthenium complexes, [{RuCl(P(OMe)3)2}2(μ-Cl)2(μ-S2)] (1), [{RuCl(P(OMe)3)2}(μ-Cl)2(μ-S2){Ru(CH3CN)(P(OMe)3)2]+ ([2]+), [{Ru(CH3CN)3(P(OMe)3)2}2(μ-S2)]3+ ([3]3+), [{Ru(CH3CN)(P(OMe)3)2}2(μ-Cl)2(μ-S2)]2+ ([4]2+), and [{Ru(CH3CN)3(P(OMe)3)2}2(μ-S2)]4+ ([5]4+), have been synthesized, their crystal structures solved.

The threat of terrorism has spread all over the world, and situation become grave. Suspicious object detection in Internet Things (IoT) is an effective way to respond global terrorist attacks. traditional solution requires performing security checks one by at entrance each gate, resulting bottlenecks crowding. In IoT paradigm, it necessary be able perform suspicious on moving people. Artificial intelligence (AI) millimeter-wave imaging are advanced technologies field. However, for persons...
Abstract The energy shifts of the SKα doublet have been measured in fifty sulfur compounds solid or liquid states, using rhombic as a standard. values were same those obtained by Faessler and Goehring, although slight discrepancy was observed on sulfites sulfates. mean number valence electrons, N, associated with atom has then calculated from according to theoretical correlation presented Coulson Zauli. N found be 6.7, 6.3, 5.2, 4.7, 4.3 for inorganic sulfides, organic sulfoxides, sulfites,...
In the non-terrestrial network (NTN) being considered for Beyond 5G (B5G), high-altitude platform systems (HAPS) and low earth orbit (LEO) satellites will be used as communication platforms. This paper proposes a feeder link in HAPS LEO using THz band from viewpoint of high speed capacity. has feature ensuring performance even cloudy or light rain compared to free space optical (FSO). this paper, budget is clarified by estimating propagation loss under various weather conditions based on...
The involvement of smart grid in home and building automation systems has led to the development diverse standards for interoperable products control appliances, lighting, energy management security. Smart enables a user usage according price demand. These have been developed parallel by different organizations, which are either open or proprietary. It is necessary arrange these such way that it easier potential readers easily understand select suitable standard their functionalities without...

This paper deals with the development of a method microanalysis inclusions by means ion microanalyzer. In this method, beam works not only to analyze inclusion fluid, but also sputter host mineral which encloses an inclusion. The fluid are kept frozen avoid rapid evaporation into vacuum. ionization properties aqueous solution in state were investigated, since such study had never been done. Semi-quantitative analysis is possible, using relative intensities and molarity Results reported on...
Abstract Reaction of [{Ru(CH3CN)3[P(OMe)3]2}2(μ-S2)](PF6)3 with a mixture acetylene and O2 gave novel ruthenium(IV) dimer complex [{Ru(IV)(PFO3)[P(OMe)3]2}2(μ-S)(μ-PF2O2)2]. The newly formed bridging terminal ligands PF2O2− PFO32− are produced from the reaction PF6− trace amounts H2O in solvent. Although is not incorporated final product, it necessary to accelerate reaction. Ruthenium(IV) complexes S2− ligand rare only two examples previously known. crystal...
A method of final confirmation methylmercury chloride (MMC) in waste water at the level 1 ppb has been established by a combination concentration technique and gas chromatographymass spectrometry (GC-MS).First, MMC sample 500 ml was concentrated about 175 times to benzene phase according solvent extraction developed Nishi. Further was, however, required for present purpose, because still lower sensitivity modern GC-MS apparatus.Various techniques were examined, but following evaporation...
複雑な試料中の酸性成分の分布を迅速に知る方法として,アルカリカラムにより混合物中の酸性成分を選択的に除去する方法を確立した.すなわち,石英粉末に115%カセイカリを担持させたカラムを分離カラムの後に接続し,分離条件と同一の温度,流速下でガスクロマトグラフィーを行なえば,カルボン酸類,フェノール類は混合物から分離されたのち完全に除去される.しかし中性成分はその保持時間,ピークの形,高さになんら影響を受けない.したがって,アルカリカラムを接続した時得られるクロマトグラムを,接続しない時に得られるクロマトグラムと比較することにより,混合物中の各成分ピークの迅速な類別ができる.また活性な水素を有するインデン,ピロール類やケトステロイドも除去されることがわかったので,活性な水素を有する化合物と安定な中性化合物との類別に本法を適用できる.
The pandemic of the COVID-19 [1] has reawakened people that viruses are still greatest threat to human society. Quarantining patients and tracking close contacts been used for hundreds years in battle between humans plague, which useful today. In information society, we can employ communications technology (ICT) suppress spread epidemics lower epidemic curve. By using spatiotemporal information, trace trajectories their contacts.

Transmission latency presents a significant challenge when operating remote equipment, such as robotic arm. To address this, we developed platform and conducted experiments to reduce transmission near-zero levels. These employed Long Short-Term Memory (LSTM) anticipate future motion trends, leveraging both the controller's movement variables Electromyography (EMG) data from operator's arm muscles. Our findings indicate potential decrease by approximately 500ms. Additionally, our research...
