Searching Speech Keywords from Video

Video contains various types of data that can be extracted using various techniques and tools. The extracted data can be used in developing video retrieving and indexing systems. Video's speech is rich with information and can be used by students as a supporting tool in learning process. Video is divided into many parts depending on their content. Searching for the part of interest may require manual searching through the entire video which may be time consuming. Therefore, this study focuses on investigating the existing approaches of searching and retrieving videos and to develop a method to make video content more easily searchable. A web-application prototype was developed using Java and JSP for searching the video speech using keywords. Finally, the users' satisfaction of the developed prototype was measured using IBM CSUQ questionnaire

Adenosine A2A Receptor Blockade Prevents Rotenone-Induced Motor Impairment in a Rat Model of Parkinsonism

Pharmacological studies implicate the blockade of adenosine receptorsas an effective strategy for reducing Parkinson’s disease (PD) symptoms. The objective of this study is to elucidate the possible protective effects of ZM241385 and 8-cyclopentyl-1, 3-dipropylxanthine, two selective A2A and A1 receptor antagonists, on a rotenone rat model of PD. Rats were split into four groups: vehicle control (1 ml/kg/48 h), rotenone (1.5 mg/kg/48 h, s.c.), ZM241385 (3.3 mg/kg/day, i.p) and 8-cyclopentyl-1, 3-dipropylxanthine (5 mg/kg/day, i.p). After that, animals were subjected to behavioral (stride length and grid walking) and biochemical (measuring concentration of dopamine levels using high performance liquid chromatography, HPLC). In the rotenone group, rats displayed a reduced motor activity and disturbed movement coordination in the behavioral tests and a decreased dopamine concentration as foundby HPLC. The effect of rotenone was partially prevented in the ZM241385 group, but not with 8-cyclopentyl-1,3-dipropylxanthine administration. The administration of ZM241385 improved motor function and movement coordination (partial increase of stride length and partial decrease in the number of foot slips) and an increase in dopamine concentration in the rotenone-injected rats. However, the 8-cyclopentyl-1,3-dipropylxanthine and rotenone groups were not significantly different. These results indicate that selective A2A receptor blockade by ZM241385, but not A1 receptor blockadeby 8-cyclopentyl-1,3-dipropylxanthine, may treat PD motor symptoms. This reinforces the potential use of A2A receptor antagonists as a treatment strategy for PD patients

Značajke građe i optička svojstava otpuštenih tankih slojeva cdin2se4

CdIn2Se4 chalcogenides thin films were prepared by thermal evaporation process. The effect of thermal annealing in vacuum on the growth characteristics of the deposited films was studied using X-ray and transmission electron microscopy techniques. It was observed that the as deposited films (300 K) were poorly crystalline. The degree of crystallinity increases with increasing the annealing temperature from 300 to 500 K. The compositional elemental analysis of CdIn2Se4 thin films annealed at 500 K was found to be nearly stoichiometric, however, films annealed in vacuum at 575 K partially dissociated into two binary phases with CdIn2Se4 as the major phase. The effect of the annealing temperature on the dispersion of the refractive index of the deposited films was investigated and analyzed within the single effective-oscillator approach. Changes of the dispersion parameters were also investigated as a function of the annealing temperature. Analysis of the optical absorption data revealed the existence of allowed direct and indirect optical transitions, and both values of energy gaps decrease with increasing annealing temperature.Isparavanjem u vakuumu pripremali smo tanke slojeve halkogenida CdIn2Se4. Proučavali smo učinke toplinskog otpuštanja u vakuumu na strukturne značajke naparenih slojeva primjenom difrakcije X-zračenja i prolazne elektronske mikroskopije. Opaža se da su svježe (na 300 K) napareni slojevi slabo kristalinični. Stupanj kristaliničnosti povećava se s povišenjem temperature otpuštanja između 300 i 500 K. Analize elementalnog sastava tankih slojeva CdIn2Se4 otpuštenih do 500 K pokazale su gotovo točan stoihiometrijski sastav, međutim, slojevi otpušteni na 575 K djelomično se razlažu u dvije binarne faze, dok CdIn2Se4 ostaje glavna faza. Mjerili smo učinke otpuštanja na disperzivnost indeksa loma naparenih slojeva i analizirali ishode jedno-oscilatornim modelom. Promjene parametara disperzije također smo istraživali u ovisnosti o temperaturi otpuštanja. Analize podataka za optičku apsorpciju ukazuju na postojanje dozvoljenih izravnih i neizravnih optičkih prijelaza s padom širina procijepa za povećne temperature otpuštanja

Progressive ShallowNet for large scale dynamic and spontaneous facial behaviour analysis in children

COVID-19 has severely disrupted every aspect of society and left negative impact on our life. Resisting the temptation in engaging face-to-face social connection is not as easy as we imagine. Breaking ties within social circle makes us lonely and isolated, that in turns increase the likelihood of depression related disease and even can leads to death by increasing the chance of heart disease. Not only adults, children's are equally impacted where the contribution of emotional competence to social competence has long term implications. Early identification skill for facial behaviour emotions, deficits, and expression may help to prevent the low social functioning. Deficits in young children's ability to differentiate human emotions can leads to social functioning impairment. However, the existing work focus on adult emotions recognition mostly and ignores emotion recognition in children. By considering the working of pyramidal cells in the cerebral cortex, in this paper, we present progressive lightweight shallow learning for the classification by efficiently utilizing the skip-connection for spontaneous facial behaviour recognition in children. Unlike earlier deep neural networks, we limit the alternative path for the gradient at the earlier part of the network by increase gradually with the depth of the network. Progressive ShallowNet is not only able to explore more feature space but also resolve the over-fitting issue for smaller data, due to limiting the residual path locally, making the network vulnerable to perturbations. We have conducted extensive experiments on benchmark facial behaviour analysis in children that showed significant performance gain comparatively

Synthesis of New Formyl Halo N-methylimidazole Derivatives

Bromo-formyl imidazoles 16-20 have been prepared by three different ways. The first consisted of conversion of bromo or iodo imidazoles 1-6 into diethyl acetals 13-15, and subsequent hydrolysis into formyl derivatives 7-9. In the second, bromination of. formyl imidazoles with NBS afforded compounds 16-18 in 45-70°/o yield. The third method used direct formylation of bromo imidazoles 10-12 with n-BuLi/DMF reagent into compounds 16, 19, and 20

Proposed Hybrid Power System for Short Route Ferries

A fractional fuel consumption saving as well as pollution cuts will be a thinking pattern or a key concern in modern ship designs. Recent advances in technology for solar cells and photovoltaic (PV) modules have resulted in solar power being a cost-effective fuel reduction alternative for this objective. This paper is intended to provide a hybrid solar diesel power system for short-run ferries. This work proposes and emphasizes the energy efficiency, cost efficiency and minimal environmental impact of hybrid-powered ferries with solar diesel. The proposed system has been studied on the example of passenger-car ferry connecting the two banks of the Suez Canal at Port Said city - Egypt. Economic and environmental analyses have been conducted to determine and measure the advantages of the proposed system. The results show an economically viable and environmentally sustainable system if it were treated as a long-term investment. Compared to the equivalent diesel generator system, this system reduces exhaust emissions by about 375 tonnes per year. The fuel cost savings achieved are also significant

Planning internship programs: Tourism students\u27 perceptions

Internship programs bridge the gap between formal education and practical work experience. Designing internship programs and involving student interns are significant themes in tourism research whose inter-relationship has been largely neglected. This paper seeks to explore how tourism students\u27 perceptions can be used to develop successful industry-based internship (IBI) programs. This is a subject that has received relatively scant attention since the publication of a number of seminal papers produced in the mid to late 1970s and early 21th century. A number of key themes or issues will be highlighted, all central to the thinking of the internship program planners. These include an analysis of internship cycles and components and the need to add value and increase students\u27 ability to move theory into practice. Using a quantitative paper-based questionnaire survey of 47 items, the findings revealed that respondents had significantly different perceptions regarding their inclusion role and importance in designing internship programs. The paper presents a valuable conceptual and planning model called PPAF Cycle to achieve effective internship programs, which strengthen the interns\u27 input. The study concludes that innovative planning ways should be found to ensure the interns\u27 full involvement in building training program plans in an increasingly mature Egyptian educational tourism system
