Robotic Remote Surveillance and Control through Speech Recognition

This paper deals with the remote based robotic surveillance system and control through speech processing. Robotic remote surveillance and control through speech recognition is a kind of simple Cyber Physical system. Cyber Physical system is connection between cyber world and physical world around us. Sensors in network map the physical parameters in digital, share the information with processors and CPS intelligently makes the decision after computing. Finally the decision command is translated into physical world by actuators. The speech commands from a user’s distant location are carried over wirelessly to a multifunctional robot unit. Robotic arm over a base will act for voice commands sent over media. Desired surveillance will be facilitated by movement of robot and installed surveillance unit. Video stream feed to user is sensing of physical environment while actions of arm represent the role of actuator. This system used in the heavy industry in any environment

Integrated multisectoral strategy to improve girls' and women's nutrition before conception, during pregnancy and after birth in India (Swabhimaan): protocol for a prospective, non-randomised controlled evaluation

INTRODUCTION: Swabhimaan is a community-based programme to improve adolescent girls’ and women’s nutrition in the rural areas of three Indian states—Bihar, Chhattisgarh and Odisha with high prevalence of undernutrition. METHODS AND ANALYSIS: Swabhimaan has a nested prospective, non-randomised controlled evaluation. Since 2017, five intervention sites receive community-led interventions through national government’s livelihood mission supported women’s self-help group federations and five control sites will initiate these activities 36 months later, in 2020. Community-led activities aim to improve coverage of 18 interventions including adequacy of food consumed, prevention of micronutrient deficiencies, access to basic health services and special care of nutritionally ‘at risk’ girls and women, improving hygiene and access to water and sanitation services and access to family planning services. The evaluation includes baseline (2016–2017), midline (2018–2019) and endline (2020–2021) surveys covering 6638 adolescent girls, 2992 pregnant women and 8755 mothers of children under 2. The final impact analysis will be by intention to treat, comparing primary and secondary outcomes in five intervention areas and five control areas. The primary outcomes are: (1) a 15% reduction in the proportion of adolescent girls with a body mass index (BMI) <18.5 kg/m2; (2) a 15% reduction in the proportion of mothers of children under two with a BMI <18.5 kg/m2 and (3) and a 0.4 cm improvement in mean mid-upper arm circumference among pregnant women. ETHICS AND DISSEMINATION: All procedures involving human subjects were approved by the Institutional Ethics Committee of the All India Institute of Medical Sciences, Bihar, Chhattisgarh and Odisha and in compliance with guidelines laid down in the Declaration of Helsinki. Evidence will inform maternal and preconception nutrition policy at national and state level. TRIAL REGISTRATION NUMBER: 58261b2f46876 and CTRI/2016/11/007482; Pre-results

Revisitando as extranets de projeto: uma análise dos processos de projeto

ResumoAs extranets de projeto foram amplamente investigadas há alguns anos. No entanto, pouco esforço tem sido dedicado à análise de como seu uso evoluiu nas empresas de AEC. Nesse sentido, o presente trabalho revisita as extranets de projeto com uma nova perspectiva, analisando evoluções em seu uso. A extranet objeto de estudo foi desenvolvida em parceria entre universidade e empresas, e seu uso foi analisado em dezenas de empreendimentos ao longo de oito anos. O método de pesquisa apresenta a forma de estudo de casos múltiplos. As funcionalidades da extranet foram desenvolvidas de maneira progressiva, e seu uso foi analisado por meio de observação direta de rotinas de trabalho, acesso a todos os documentos de dezenas de empreendimentos, análise do fluxo de trabalho nos empreendimentos e entrevistas com coordenadores de projeto. Entre os principais resultados destacam-se: a) o uso prolongado da ferramenta permitiu que as empresas consolidassem rotinas de gestão do processo de projeto, melhorando a gestão de documentos e as formas de comunicação; b) esse uso não implicou, na maioria dos casos, a criação de novos mecanismos de colaboração entre os usuários, com exceções pontuais; c) o amadurecimento no uso das extranets permitiu a ampliação de seu uso, estendendo-se a outros setores das empresas e fases dos empreendimentos. O trabalho discute como as extranets, com o uso consolidado nas empresas, podem servir como efetivos instrumentos de colaboração na etapa de projeto

Electrochemical Behavior of Ce(IV)/Ce(III) Couple in N,N‐Di(2‐ethylhexyl)‐n‐butanamide (DEHBA), N,N‐Di(2‐ethylhexyl)‐iso‐butanamide (DEHiBA), and N,N‐Di(2‐ethylhexyl)‐3,3‐dimethyl Butanamide (DEHDMBA)

International audienceIn this work we report on the electrochemical behavior of Ce(IV)/Ce(III) redox couple in pure N,N-dialkyl amides (N,N-DA), namely N,N-di(2-ethylhexyl)-n-butanamide (DEHBA), N,N-di(2-ethylhexyl)-iso-butanamide (DEHiBA), and N,Ndi(2-ethylhexyl)-3,3-dimethyl butanamide (DEHDMBA) equilibrated with nitric aqueous solutions as an entry to the direct electrochemical characterization of plutonium in these extractants. Ce(IV)/Ce(III) redox process was used as a model. Its potential (E 1/2 1.02 V/SCE) is not affected by the temperature and the nature of the N,N-DA and this clearly indicates that the functionalities of the these extractants produce the same relative effect on both +IV and +III oxidation states of the cerium cation. Linear variations of the current intensity of the reduction peak of Ce(IV) with the concentration of Ce(IV)/N,N-DAs/HNO 3 (5M) solutions were obtained from cyclic voltammograms recorded at 25°C and 40°C. Due to the poor definition of the voltammograms in DEHiBA and DEHDMBA, such characterization allows only the evaluation of the performances of the chemical extraction of Ce(IV) from aqueous nitric acid solution by the undiluted DEHBA. To our knowledge, the electrochemical behavior of Ce(IV)/Ce(III) in N,N-DAs was not previously studied and our findings will for sure open the door for further investigations in this field
